1 1999-12-28 Gary Houston <ghouston@arglist.com>
3 * posix.c (scm_waitpid): move the HAVE_WAITPID test out of the
4 procedure body, so that the procedure is left undefined if waitpid
5 is not available. previously in this case the procedure was
6 defined but would raise a system-error when called, which is
7 pointless. I intend to make the same change for other procedures
8 and deprecate SCM_SYSMISSING and scm_sysmissing.
10 1999-12-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
12 * feature.c (s_scm_add_hook_x): Call scm_wrong_type_arg instead of
13 scm_misc_error when add-hook! is passed a procedure of wring
14 arity. (Thanks to Greg Harvey.)
16 1999-12-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
18 * macros.c (scm_make_synt): Use scm_make_subr_opt to make the
19 transformer subr. (Thanks to Bill Schottstaedt.)
21 1999-12-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
23 * objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR
24 setting struct table class.
26 Sun Dec 19 10:22:34 1999 Greg J. Badros <gjb@cs.washington.edu>
28 * threads.c, mit-pthreads.c, list.c, coop.c: Remove K&R
29 prototypes; just use ANSI C prototypes. I'm not sure how
30 mit-pthreads.c ever compiled -- it still doesn't for me, but the
31 normal make procedure does not try to build it anyway (even
32 --with-threads I get the other threads code building) so I'm not
35 Sat Dec 18 16:58:34 1999 Greg J. Badros <gjb@cs.washington.edu>
37 * tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of
38 SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
39 in terms of SCM_SLOPPY_NCONSP instead of repeating the
42 * symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
43 define latter in terms of sloppy variant.
45 * strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
46 define latter in terms of sloppy variant.
48 * scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
49 out the commonality of the various basic SCM_VALIDATE_foop
50 macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
51 SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
52 coercion to an integer which is more advanced than desired and
53 SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
54 appropriately for the various _MIN, _MAX, _RANGE macros. Drop
55 some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
56 SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
57 part of its SCM_CONSP test).
59 * socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
60 SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
62 Sat Dec 18 15:33:05 1999 Greg J. Badros <gjb@cs.washington.edu>
64 * dynl.c: Added #include "scm_validate.h"
66 Sat Dec 18 15:22:10 1999 Greg J. Badros <gjb@cs.washington.edu>
68 * alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use
69 SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of
70 scm_num2long; SCM_WTA instead of scm_wta. Only done for when
71 FUNC_NAME was used as an argument of the macro and the formal
72 argument name was the explicit argument in the old function call.
73 These were just missed in my first pass of changes.
75 1999-12-18 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
77 * guile-doc-snarf.in (filename): Strip path to source dir before
78 touching the .x-files.
80 1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
82 * debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP.
84 * eval.c (SCM_CEVAL): Removed check for unbound slot in
85 SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.)
87 1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
89 * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
90 (SCM_ECONSP): Version which doesn't mix && and || without
92 (SCM_NECONSP): Bugfree version.
94 Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu>
96 * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
97 SCM_NIMP test integrated into an || clause that I'd missed before
98 and was causing a segfault in the regression tests.
100 * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
101 (char *); fixes a problem reported by the regression test
104 * ports.c: Fixed a couple of arg/number mismatches in
105 SCM_VALIDATE_ macros.
107 Now passes the (not-comprehensive) guile-modules test-suite again!
109 Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu>
111 * coop-threads.c: Remove K&R function headers.
113 * scm_validate.h: Added SCM_VALIDATE_THREAD.
115 * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
116 that SCM_FOOP macros all now include SCM_NIMP in their expansion.
117 This simplifies lots of code, making it far more readable.
119 Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu>
121 * *.h: Use SCM_NIMP(X) && in all the FOOP macros.
123 * *.[ch]: Use do { ... } while (0) idiom in macros that expanded
126 Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu>
128 * snarf.h: Put SCM_PROC and SCM_PROC1 back in for
129 backward-compatibility of packages that use Guile. Internally
130 Guile should not use them, though. (Maybe enforce this with a new
131 -DBUILDING_GUILE compile-time flag?).
133 Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu>
135 * backtrace.c (scm_set_print_params_x): Renamed from
138 * guile-doc-snarf.in: Use guile-snarf.awk, not
139 guile-doc-snarf.awk. Pass the basename of $filename
141 * load.h: Added prototypes for scm_sys_library_dir,
144 * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these
145 functions, and took out the old scm_library_dir, scm_site_dir,
146 scm_pkgdata_dir. Now the primitives are %package-data-dir
147 (already existed), %library-dir, and %site-dir.
149 * debug.c: Use SCM_MISC_ERROR when possible instead of using
150 s_scm_* in a scm_misc_error() call.
152 * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make
153 using guile-doc-snarf send stdout to $@ to create the .x file like
156 * guile-snarf.awk.in: Added.
158 * guile-doc-snarf.awk.in: Removed (sorry to back out a recent
159 commit; if we're going to switch to guile-snarf I figure it makes
160 sense to get this right now-- I'd already had the change in my
161 working copy when the below commit happened).
163 1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
165 * guile-doc-snarf.awk: Removed.
167 * guile-doc-snarf.awk.in: Added.
169 * ports.c (s_scm_pt_member): Fixed validation.
171 * guile-doc-snarf.in (filename): Use basename in order to strip
174 * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
176 (scm_memcons, scm_memcons, mem_to_proc): Renamed function name
179 * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
181 * tags.h (SCM_UNBOUND): New iflag which is needed for some time to
182 mark the unboundness of a GOOPS slot. (Added now in order to
183 correct a oversight. Should probably be removed again and
184 replaced with SCM_UNDEFINED when the corresponding code in GOOPS
187 * print.c (scm_isymnames): Added printed representation for
190 * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
193 Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
195 * strings.c: Fixed mistaken default value in
196 scm_make_shared_substring; thanks Eric Moore!
198 Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu>
200 * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
201 replacement for docstrings. Fixes problem Ryan Yeske observed
202 with using mawk on his system. Thanks Ryan!
204 Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu>
206 * guile-doc-snarf.in: Do not echo to stdout since the output now
207 gets stuck directly in the files instead of redirected from
210 * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
211 Yeske. Use print instead of printf to prime the .x file since
212 AIX's cpp has problems with #include-ing empty files (according to
213 the old guile-snarf.in file).
215 Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu>
217 * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
218 GUILE_PROC1. Build guile-procedures.txt, and add that file to
221 * load.c: Added `pkgdata-dir', `site-dir', `library-dir'
224 * guile-doc-snarf.awk: Drop trailing space when no arguments:
225 e.g., "(foo )" is now "(foo)".
227 * *.c, alist.c: moved all the documentation for primitives from
228 guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
229 This leaves about half of the primitives undocumented. Also, all
230 the markup is currently still texinfo. I don't have a problem
231 with texinfo per se, but the markup is not very descriptive or
234 Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu>
236 * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
237 SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
238 argument mismatches (along with the FUNC_NAME macro checking) by a
239 static tool that runs directly over the .c files.
241 * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The
242 docstring is still missing from the .doc file; it just gives the
243 name of the C function that gets called instead.
245 * guile-doc-snarf.awk: Be sure to touch the output files to help
246 make out. Also handle SCM_REGISTER_PROC better, and change the
247 output format slightly.
249 Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu>
251 * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
252 guile-doc-snarf script.
254 * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
255 extraction system. Builds foo.x, foo.doc from foo.{c,cc}.
256 There are dependencies between these files and snarf.h. This
257 replaces guile-snarf.
259 * guile-snarf.in: Drop everything after $$$ for the new snarf.h
260 macros. This is obsoleted by guile-doc-snarf, but kept here for
261 now for good measure.
263 * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
264 bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating
265 .doc files to use guile-doc-snarf. Update the rule for creating
266 .x files to use guile-doc-snarf.
268 Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu>
270 * *.c: Finish replacing K&R style prototypes with ANSI C
273 * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
274 char *. ANSI prototypes caught this.
276 * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
279 * scm_validate.h: Use SCM_BOOLP for validating bools. Do not
280 expand macros if SCM_DOCSTRING_SNARF.
282 Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
284 * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
285 SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
288 Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu>
290 * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
293 * scm_validate.h: Moved above out into boolean.h, fix typo in
294 SCM_VALIDATE_NIM macro.
296 Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu>
298 * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
299 (none of the other validate macros have the trailing P).
301 Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu>
303 * scm_validate.h: Added the FSF copyright to the top.
305 * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of
306 SCM_ASSERT w/ SCM_OUT_OF_RANGE.
308 Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu>
310 * Makefile.am: Added scm_validate.h to modinclude_HEADERS.
312 * *.c: Pervasive software-engineering-motivated rewrite of
313 function headers and argument checking. Switched SCM_PROC,
314 SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
315 later, but was useful to keep old versions around while migrate)
316 that has docstrings and argument lists embedded in the GUILE_PROC
317 macro invocations that expand into a function header. Use lots of
318 new SCM_VALIDATE_* macros to simplify error checking and reduce
319 tons of redundancy. This is very similar to what I did for Scwm.
321 Note that none of the extraction of the docstrings, nor software
322 engineering checks of Scwm is yet added to Guile. I'll work on
323 that tomorrow, I expect.
325 * chars.c: Added docstrings for the primitives defined in here.
327 * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
328 SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
329 still remains for now. Changed naming convention for the s_foo
330 string name of the primitive to be s_scm_foo for ease of use with
333 * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
334 argument checking through guile. Maybe some of these should be
335 folded into the header file for the types they check, but for now
336 it was easiest to just stick them all in one place.
338 1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)
340 * smob.c (scm_smob_prehistory): initialize allocated smob
342 * tags.h: new tag: scm_tc16_allocated
344 * gc.c (scm_gc_for_newcell): set the car of the new cell
345 to scm_tc16_allocated
346 * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
347 (scm_gc_mark): mark allocated cells.
349 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
351 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
352 thanks to Dirk Hermann.
354 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
355 gh_eval_str_with_standard_handler,
356 gh_eval_str_with_stack_saving_handler): Fix constness. Some
357 thanks to Dirk Hermann.
359 * gh_data.c (gh_str02scm): Fix constness.
361 * gh.h: Fix constness of prototypes for the above.
363 * vectors.c: Include "unif.h" to avoid a warning about missing
364 prototype for scm_uniform_element_size().
366 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
368 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
369 Turned into primitive generics.
371 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
373 * ports.c (scm_port_closed_p): new procedure, implements
374 "port-closed?" suggested by Bernard Urban.
375 ports.h: added prototype, removed the SCM_P macros.
377 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
379 * unif.h: added some comments, removed the SCM_P macros.
381 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
383 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
384 (thanks to Daniel Skarda).
386 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
388 * gscm.c, gscm.h: Deleted. They were unused.
390 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
392 * unif.c (scm_list_to_uniform_array): call
393 scm_dimensions_to_uniform_array with a third argument of
394 SCM_UNDEFINED instead of SCM_EOL.
396 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
398 * the following changes allow guile to be built with the array
399 "module" omitted. some of this stuff is just tc7 type support,
400 which wouldn't be needed if uniform array types were converted
403 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
405 (scm_tag): don't check array types unless HAVE_ARRAYS.
407 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
408 remove the unused array types.
409 * (scm_stable_sort, scm_sort): don't support vectors if not
410 HAVE_ARRAYS. a bit excessive.
412 * random.c (vector_scale, vector_sum_squares,
413 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
414 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
416 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
417 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
418 gh_uniform_vector_length, gh_uniform_vector_ref):
419 don't define unless HAVE_ARRAYS.
420 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
422 don't check vector types if not HAVE_ARRAYS.
424 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
425 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
426 don't support the array types unless HAVE_ARRAYS is defined.
428 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
430 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
431 defined (this should use read-hash-extend).
433 * ramap.c, unif.c: don't check whether ARRAYS is defined.
435 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
436 scm_uniform_element_size if HAVE_ARRAYS.
437 vectors.h: prototype too.
439 * unif.c (scm_uniform_element_size): new procedure.
441 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
442 scm_init_unif unless HAVE_ARRAYS is defined.
444 * __scm.h: don't define ARRAYS.
446 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
447 moved here from libguile_la_SOURCES.
449 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
451 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
452 functions for network data conversion.
454 * numbers.c (scm_num2long, scm_num2longlong):
455 throw out-of-range instead of wrong-type-arg if appropriate.
456 (scm_iint2str): handle -2^31 correctly.
457 (scm_num2long): handle -2^31 bignum correctly.
458 (scm_num2long_long): rewrite the bigdig case: basically copied
460 numbers.h: (SCM_BITSPERLONGLONG): deleted.
462 * unif.c (rapr1): use sprintf instead of intprint for unsigned
463 longs: intprint can't cope with large values.
465 * numbers.c (scm_num2ulong): check more consistently that the
466 input is not negative. if it is, throw out-of-range instead of
469 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
470 uvect, ivect or llvect.
471 Check that fill doesn't overflow short uniform array.
473 * __scm.h: add another long to the definition of long_long and
476 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
477 print representation of llvect. read can't handle more than
479 (scm_dimensions_to_uniform_array): make "fill" an optional argument
480 instead of a rest argument.
482 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
485 * __scm.h: don't mention LONGLONGS.
487 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
488 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
490 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
492 * net_db.c (scm_inet_aton): throw errors using the misc-error key
493 instead of system-error. inet_aton doesn't set errno.
494 system-error isn't right in gethost either, since it's throwing
495 the value of h_errno instead of errno. so:
496 (scm_host_not_found_key, scm_try_again_key,
497 scm_no_recovery_key, scm_no_data_key): new error keys.
498 (scm_resolv_error): new procedure, use the new keys.
499 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
501 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
503 * error.c: (various): use scm_cons instead of scm_listify
504 to build short lists.
506 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
508 * socket.c (scm_fill_sockaddr): zero the address structure before
509 use, in case it has a sin_len field and the OS doesn't like random
510 values (thanks to Bertrand Petit).
512 1999-10-26 Mark Galassi <rosalia@lanl.gov>
514 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
515 a const char * argument, upon suggestion from Lynn Winebarger.
517 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
519 * strports.c (st_end_input): avoid dubious pointer arithmetic.
521 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
523 * Move the responsibility for resetting port buffers from the
524 caller of the ptob seek procedure to the implementation. This
525 gives more control in general to the ptob seek: in particular the
526 change of 1999-10-20 can be made to work without breaking seek on
527 string ports. There's a comment in NEWS about upgrading port
530 * ports.c (scm_seek): don't reset the port buffers here.
532 * fports.c (fport_seek): reset the buffers, except for the
535 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
536 offset. check that it's not less than read_buf.
537 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
538 case and currently reading.
540 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
542 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
543 so that unread chars are not needlessly discarded. (thanks to
546 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
548 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
549 random access. rw_active needs to be maintained even for single
550 directional ports, otherwise scm_seek and probably other things are
551 broken. (thanks to Roland Orre).
553 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
555 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
557 * ports.h (scm_port): change the comments on rw_random and rw_active.
559 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
561 * ioext.c: Added #include "feature.h".
563 These changes turns `delay' into a memoizing macro. This is
564 because it may be expanded before evaluation if it occurs at the
565 beginning of a body. (Thanks to Lauri Alanko.)
567 * eval.c, eval.h (scm_sym_delay): New global symbol.
569 * tags.h (SCM_IM_DELAY): New immediate symbol.
571 * print.c (scm_isymnames): Printed representation.
573 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
574 (scm_m_delay): Turned into a memoizing macro.
576 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
578 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
580 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
581 protected from GC while building the vector. (Thanks to Bernard
582 Urban and Greg Harvey.)
584 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
586 * throw.c (handler_message): Display backtrace if backtraces
589 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
591 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
592 the autogen.sh script to create generated files like these.
594 * numbers.c (scm_string_to_number): Signal an error if radix is
595 less than two. (Thanks to Jorgen Schaefer.)
597 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
598 Don't assume that the current output port is valid. Somebody
599 might close it. (Thanks to Bernard Urban.)
601 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
603 * scmconfig.h.in: Regenerated.
605 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
607 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
609 * __scm.h: Fix a bunch of macros that were missing do-while(0)
612 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
613 semicolon) exposed by the above change.
615 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
617 * stacks.c: Avoid compiler warning re: unitialized var.
619 * scmconfig.h.in: Added DEBUG_FREELIST
621 * pairs.h: Fix macro that was not do-while(0) sandwiched.
623 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
626 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
628 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
629 instead of in scm_init_filesys.
631 * init.c (scm_boot_guile_1): don't call scm_init_posix or
632 scm_init_filesys unless HAVE_POSIX is defined.
633 don't call scm_init_netdb or scm_init_socket unless
634 HAVE_NETWORKING is defined.
636 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
637 net_db.c, socket.c: moved here from libguile_la_SOURCES.
639 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
641 * root.c (scm_make_root): Initialize all the fields of the new
642 root. GC could happen any time, you know. (Thanks to Greg
645 * numbers.c (scm_number_to_string): Signal an error if radix is
646 less than two. (Thanks to Jorgen Schaefer.)
648 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
649 so automake will actually generate rules for it.
650 * Makefile.in: Regenerated.
652 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
654 * backtrace.c: #include "_scm.h" before testing whether
655 HAVE_UNISTD_H is #defined.
657 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
659 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
660 * ports.c (scm_read_char): Same.
661 * ioext.c (scm_read_line): Same.
662 (Thanks to Bernard Urban.)
664 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
666 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
668 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
669 checking may invoke a generic. (Thanks to Michael Livshin.)
671 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
673 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
674 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
675 generic function if the asubr is called with only one arg.
677 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
679 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
680 HAVE_RESTARTABLE_SYSCALLS.
681 (scm_init_scmsigs): use siginterrupt if it's available. not
682 everyone who has restartable syscalls has SA_RESTART it seems.
684 (scm_sigaction): use scm_num2long/scm_long2num when converting
685 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
686 scm_integer_p to test the type.
688 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
690 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
691 HAVE_RESTARTABLE_SYSCALLS.
693 * strports.c (scm_strport_to_string): create the string from
694 pt->read_buf instead of an expression that evaluates to the
697 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
698 from the port: the port's buffer may not be NUL terminated.
700 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
702 * Makefile.am (.c.x): Added missing semicolon after `false'.
704 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
706 * print.c (scm_iprin1): Turn `write' and `display' into
707 primitive generics and use their associated generic functions in
708 scm_iprin1 for GOOPS objects.
710 * backtrace.c: #include <unistd.h> if present.
712 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
714 * Makefile.am (.c.x): Don't create a subshell just to delete the
715 .x file and return false.
716 * Makefile.in: Regenerated.
718 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
720 * feature.c (scm_create_hook): New function. Replaces
721 scm_make_named_hook which is now deprecated.
722 (scm_make_hook_with_name): New primitive.
723 (print_hook): Hooks now print in a fancy way.
725 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
727 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
728 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
729 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
730 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
731 struct.h: Updated copyright notices.
733 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
734 of SCM_NCONSP. (Thanks to Greg Badros.)
736 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
739 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
741 * backtrace.c: Keep backtraces within specified width by
742 adaptively adjusting fancy printing parameters and cut output if
744 (scm_display_application): Check args.
746 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
748 Change the name of the objects returned by OPENDIR from
749 "directory" to "directory stream". A predicate named "directory?"
751 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
752 At the Scheme level, "directory?" -> "directory-stream?".
753 (scm_dir_print): Use the phrase "directory stream" in printed form.
754 * filesys.h (scm_directory_stream_p): Prototype renamed
757 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
758 be removed by `make distclean', since it's generated by configure.
759 * Makefile.in: Regenerated.
760 (Thanks to Robert Bihlmeyer.)
762 * strop.c (scm_substring_move_x): Signal an error if start1
763 doesn't come before end1. (Thanks to Karoly Lorentey).
765 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
766 calling SCM_NIMP. (Thanks to Karoly Lorentey).
768 * version.c (scm_libguile_config_stamp): Deleted. See
769 corresponding change to ../ice-9/boot-9.scm.
770 * versiondat.h.in: Remove definition for GUILE_STAMP.
771 * version.h: Delete prototype.
772 * Makefile.in: Regenerated.
774 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
776 * filesys.c (scm_directory_p): new procedure "directory?" Returns
777 a boolean indicating whether its argument is a directory
778 port as returned by opendir (thanks to Dirk Herrmann for the
781 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
783 * backtrace.c (display_frame_expr): Don't print a newline.
784 (display_frame): Print the newline here instead.
785 (display_backtrace_body): Don't print "Backtrace:".
786 (scm_backtrace): Print "Backtrace:" here instead.
788 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
790 * procs.c (scm_setter): Signal WTA if handed an entity or operator
793 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
794 primitives. (Thanks to Greg Badros);
795 (scm_hook_to_list): New primitive; Hooks are now smobs.
797 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
799 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
800 of #f for the 10th vector element to avoid an exception
801 seen by Bernard Urban.
802 (scm_mktime): unneeded ASSERT removed.
804 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
806 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
809 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
811 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
813 * numbers.c: Converted comparison operations to dispatch on
814 generic if args don't match.
816 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
818 1999-09-06 James Blandy <jimb@mule.m17n.org>
820 * guile-snarf.c: Deleted. Snarfing should respect CPP
821 conditionals, so it needs to actually run CPP. Bleah.
823 1999-09-05 James Blandy <jimb@mule.m17n.org>
825 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
826 * guile-snarf.in: Be sure to exit with an error if CPP does.
827 * Makefile.am (.c.x): Delete the .x file and exit with an error
828 status if guile-snarf exits with an error status.
829 * Makefile.in: Regenerated.
831 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
832 scm_makekey, which doesn't exist any more. Guess nobody's using
835 * guile-snarf.c: New implementation of guile-snarf, meant to be
836 more robust than the shell script. I think it's complete, but I
837 haven't tested it at all, and I haven't changed the build process
838 to actually use it. We should compare its output against that of
839 the existing shell script, for all source files.
841 * guile-snarf.c (parse_args): Abort if we haven't handled some
844 1999-09-03 James Blandy <jimb@mule.m17n.org>
846 * load.c (scm_search_path): If the filename has any extension at
847 all, ignore the entire list of extensions. Also, don't check whether
848 the file is accessible. If the file exists, accessible or not, we
849 should return it. Inaccessible files should cause an error later.
850 (Thanks to Keisuke Nishida for the suggestions.)
852 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
854 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
855 atexit not available. (sunos4.1.4 needs it.)
857 1999-09-01 James Blandy <jimb@mule.m17n.org>
859 I take it all back --- bcopy does handle overlapping source and
860 destination areas correctly. At least on every system I could
861 find. But it is better to use AC_REPLACE_FUNCS than to introduce
862 new CPP conditionals.
863 * memmove.c: New file, implementing memmove in terms of bcopy.
864 * scmconfig.h.in: Regenerated.
866 Allocators should use the `void *' type for generic pointers.
867 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
868 argument and return types.
869 * gc.h: Corresponding changes to prototypes.
872 1999-08-31 James Blandy <jimb@mule.m17n.org>
874 * numbers.c (scm_init_numbers): Claim to support the `complex'
875 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
877 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
878 find (ice-9 boot-9) when Guile was compiled in a separate
879 directory from the source. (Thanks to Rodney Brown.)
880 * Makefile.in: Regenerated.
882 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
883 table lengths by the size of a single element when growing the
884 table. (Thanks to Bill Schottstaedt.)
886 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
888 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
889 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
890 since that cuts down the time for type dispatch by 50%.
892 1999-08-30 James Blandy <jimb@mule.m17n.org>
894 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
895 not a correct substitute for memmove, because it doesn't handle
896 overlapping source and destination areas on many platforms.
897 Overlaps are the primary reason to use memmove in the first place.
898 * ports.c (scm_ungetc): Same.
899 * strop.c (scm_substring_move_x): Same.
901 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
903 * gc.c (scm_init_storage): Skip registration of cleanup on systems
904 which lack atexit. (Is it important that cleanup is made
905 properly? Maybe we should replace all `exit' with `scm_exit' and
908 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
909 scm_struct_free_standard, scm_struct_free_entity): Declared to
910 return scm_sizet instead of size_t.
912 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
913 there on sunos4.1.4.)
915 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
917 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
918 Account for the case when second argument is unbound.
920 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
921 (Thanks to Karoly Lorentey.)
923 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
924 isn't present. (Thanks to Suzuki Toshiya.)
926 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
929 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
932 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
933 Bernard Urban and Ian Grant.)
935 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
936 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
937 change in the representation of entities and operators.)
939 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
941 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
942 don't allocate zero bytes (thanks to Bill Schottstaedt).
944 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
946 * procs.c (scm_setter): Converted to use generic dispatch.
948 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
951 * load.c (scm_search_path): Don't try extensions which already are
952 present at the end of the filename.
953 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
955 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
957 Cleanup and simplification of generic method dispatch.
958 Also, the quadruple representation of entity and operator
959 procedures has been replaced with single.
961 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
963 * print.c (scm_isymnames): Removed #@hash-dispatch.
965 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
966 from eval.c; Support 0 arity methods.
967 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
968 (scm_apply_generic_env): Removed.
969 Replaced slots proc0-3 with procedure.
971 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
972 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
973 SCM_OPERATOR_PROCEDURE.
974 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
975 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
977 * struct.c, struct.h: Replace 4 procedure slots with one.
978 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
980 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
983 * eval.c (scm_sym_args): Removed.
984 (SCM_CEVAL): Simplified entity application.
985 Moved dispatch code to objects.c.
987 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
989 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
991 * sort.c (closureless): Use scm_eval_body.
993 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
994 with a symbol as last form was first called normally and then via
995 `map' or some other mechanism using primitive apply, an ILOC was
998 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1000 This change extends the representation of primitive procedures
1001 with more data fields, e.g. a place for documentation and true
1002 procedure properties.
1004 * procs.c, procs.h (scm_subr_entry): New type: Stores data
1005 associated with subrs.
1006 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
1007 SCM_SUBR_DOC): New macros.
1008 (scm_subr_table): New variable.
1009 (scm_mark_subr_table): New function.
1011 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
1013 * gc.c (scm_gc_mark): Don't mark subr names here.
1014 (scm_igc): Call scm_mark_subr_table.
1017 This change implements a scheme for letting a generic work as a
1018 shadow for a primitive procedure. If the primitive procedure
1019 can't dispatch on its arguments, control is left over to the
1020 generic. Normal wrong type arg errors will be generated until the
1021 user has hung the first method on the primitive.
1023 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
1025 * procs.c, procs.h (scm_subr_p): New function (used internally).
1027 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
1029 * objects.c, objects.h (scm_primitive_generic): New class.
1031 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
1033 * print.c (scm_iprin1): Print primitive-generics.
1035 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
1036 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
1038 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
1039 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
1040 primitives). NOTE: This means that it is now *required* to use
1041 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
1042 obscured representation that will be removed in the future anyway,
1043 so backward compatibility is no problem here).
1045 * numbers.c: Converted most numeric primitives (all but bit
1046 comparison operations and bit operations) to dispatch on generic
1047 if args don't match.
1050 Better support for applying generic functions.
1052 * eval.c, eval.h (scm_eval_body): New function.
1054 * objects.c (scm_call_generic_0, scm_call_generic_1,
1055 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
1059 Optimization of the generic function dispatch mechanism.
1061 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
1062 called scm_memoize_method instead of doing a second lookup.
1064 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
1069 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
1070 scm_sysintern so that the binding connected with the subr name
1071 isn't cleared when we give set = 0.
1074 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1076 More transparent handling of ports with print states.
1078 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
1079 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
1080 instead of a pair of a port and a print state. We'll need to cons
1081 once extra in scm_printer_apply but the type system will be
1082 cleaner, it will mix better with GOOPS, and, it will be even more
1083 transparent to the user.
1085 * print.c (scm_get_print_state): New procedure: Given an output
1086 port, return the print state associated to it in the current print
1087 chain, if one exists;
1088 (scm_port_with_print_state): New procedure: Associate a
1089 print-state with a port.
1090 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
1091 (scm_printer_apply): Wrap port and pstate as a smob;
1092 (print_state_printer): Removed.
1094 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
1096 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
1099 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
1100 testing (otherwise the port-print-state trick won't be transparent
1101 to the user; one example where this caused problems was in the
1102 (ice-9 format) module).
1104 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1106 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
1107 SCM_UNSPECIFIED instead of the set value.
1109 1999-08-20 James Blandy <jimb@mule.m17n.org>
1111 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
1113 * ports.h (enum scm_port_rw_active): New enum, containing
1114 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
1115 zero). The debugger knows about enums, but doesn't know about
1117 (typedef scm_port): Declare rw_active member to be an enum
1119 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
1121 * ports.c (scm_add_to_port_table): Same.
1122 * strports.c (st_flush, st_end_input): Same.
1124 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
1125 scm_must_realloc, and scm_done_malloc as appropriate.
1127 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1129 * sort.c (quicksort): Added condition to protect the algorithm
1130 from crashing the interpreter if the less predicate is buggy.
1132 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
1134 * fports.c (fport_write): fix line-buffering mode again.
1135 (scm_open_file): recognise 'l' for line-buffering.
1136 (scm_setvbuf): recognise _IOLBF for line-buffering.
1138 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1140 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
1143 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
1144 evaluating closures.
1146 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
1148 * fports.c (fport_write): use memcpy instead of strncpy, in case
1149 the data contains NUL.
1151 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1153 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
1155 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
1156 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
1157 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
1158 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
1159 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
1160 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
1161 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
1162 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
1163 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
1164 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
1165 scm_sym_ as prefix for symbols.
1167 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
1169 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
1170 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
1171 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
1172 scm_sym_atcall_cc): Made global.
1174 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1176 * eval.c (scm_sym_args): Made global.
1178 * objects.c (scm_set_object_procedure_x): Disallow setting of
1179 procedures for pure generic functions.
1181 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
1183 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
1184 Scheme name from lseek to seek, but lseek was added recently so
1185 it shouldn't be a big problem.
1186 * ports.c, gdbint.c, ioext.c: changed callers.
1188 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
1190 * fports.c (fport_input_waiting): if select is used, return 1
1191 instead of whatever FD_ISSET expands to. maybe it will be useful
1192 to interpret the value from the input_waiting ptob procedure as a
1193 lower bound on the number of bytes available.
1195 * Mikael asked for a few names to be changed...
1197 * ports.c (scm_make_port_type): take the write procedure as the
1198 second argument instead of the flush procedure.
1199 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
1200 fflush -> flush, read_flush -> end_input, fclose -> close,
1201 fill_buffer -> fill_input, ftruncate -> truncate,
1202 input_waiting_p -> input_waiting.
1204 * ports.c (end_input_void_port): was read_flush_void_port.
1205 (scm_set_port_end_input): was scm_set_port_flush_input.
1206 (scm_set_port_flush): was scm_set_port_write.
1207 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
1208 (scm_end_input): was scm_read_flush.
1209 (scm_fill_input): was scm_fill_buffer.
1210 (scm_flush): was scm_fflush.
1211 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
1212 (fport_end_input): was local_read_flush.
1213 (fport_flush): was local_fflush.
1214 (fport_close): was local_fclose.
1215 (fport_truncate): was local_ftruncate.
1216 (fport_seek): was local_seek.
1217 (fport_free): was local_free.
1218 (fport_fill_input): was fport_fill_buffer.
1219 * strports.c (st_end_input): was st_read_flush.
1220 (st_truncate): was st_ftruncate.
1221 * vports.c: (sf_flush): was sfflush.
1222 (sf_close): was sfclose.
1223 (sf_fill_input): was sf_fill_buffer.
1225 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
1228 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1230 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
1231 forms now contain the expressions to be dispatched upon instead of
1232 depending on a surrounding lambda or let; Generic function
1233 dispatch has been optimized; `apply' on a generic function now
1234 works a little bit strangely. It uses a trick so that the type
1235 dispatch code in SCM_CEVAL can be reused.
1237 * objects.h, objects.c (scm_apply_generic_env): Added (used by
1239 (scm_operator_p): Added.
1240 (scm_sym_atdispatch): Added.
1241 (scm_set_object_procedure_x): Modified to handle the new style
1243 (scm_object_procedures): New debugging procedure.
1245 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1247 * eval.c, eval.h (scm_sym_args): Added.
1249 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
1251 * feature.c, feature.h (scm_c_run_hook): Added.
1253 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
1254 cdrxnoap and loopnoap instead of begin and loop.
1256 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
1258 * ports.c (scm_putc, scm_puts),
1259 * unif.c (scm_uniform_array_write): use scm_lfwrite.
1260 * ports.c (scm_putc): change type of first argument from int to char.
1262 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1264 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
1265 SCM_IM_HASH_DISPATCH.
1267 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
1268 (scm_si_redfined, scm_si_hashsets): Moved.
1270 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
1271 flag which combines type and status info so that the class
1272 redefinition protocol has zero cost during normal execution.
1274 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
1276 * ports.h (scm_ptob_descriptor): include a write procedure again.
1277 it's more efficient for unbuffered fports (e.g., sockets.)
1279 * ports.c (scm_puts): use ptob->write.
1280 * vports.c (scm_make_sfptob): set write proc in ptob.
1281 * strports.c (scm_make_stptob): set write proc in ptob.
1282 * ports.c (write_void_port): new procedure.
1283 * vports.c (sf_write): new procedure.
1284 * ports.c (scm_lfwrite): use ptob->write.
1285 * strports.c (st_write): new procedure.
1286 * fports.c (fport_write): new procedure.
1287 (scm_make_fptob): set write in ptob to fport_write.
1288 * ports.h: prototype for scm_set_port_write.
1289 * ports.c (scm_make_port_type): initialise ptob write procedure.
1290 (scm_set_port_write): new proc.
1292 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
1294 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
1295 until we've verified that it is actually a port. (Thanks to
1298 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1300 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
1301 code, particularly an unnecessary test (len != size, where len ==
1302 size). (Was this leftovers from debugging code, or have I missed
1303 something profound?)
1305 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
1306 size. (Thanks to James Dean Palmer.)
1308 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
1309 (Thanks to Lorentey Karoly.)
1311 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1313 * eval.c (scm_m_expand_body): Use scm_cons_source.
1315 * struct.c (scm_print_struct): Use vtable name.
1317 * print.c (scm_init_print): Set name of print state type.
1319 * stacks.c (scm_init_stacks): Set name of stack type.
1321 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1323 * eval.c (SCM_CEVAL): Removed old implementation of internal
1326 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
1328 * debug.c, debug.h (scm_reverse_lookup): Added.
1329 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
1330 internal procedure definitions; Don't use scm_i_inner_name.
1332 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
1333 New isym operations.
1335 * eval.h: Added prototypes for multi language support functions.
1337 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
1338 improper lists in the low-level representation, since that will
1339 cause a begin to be prepended at macro expansion.
1341 * eval.c (scm_cons_source): Version of cons which copies source
1342 properties from an existing cell.
1343 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
1345 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
1346 procedure source before calling scm_unmemocopy instead of faking
1349 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1351 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1353 1998-07-09 Radey Shouman <radey@colorage.com>
1355 * eval.c (ceval_1): Modifications to allow rewriting of interal
1356 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1357 body of which it is the CAR is macro expanded by m_expand_body,
1358 which rewrites internal DEFINE.
1360 (m_expand_body): Added.
1362 (m_macroexp1): Added argument to control error checking:
1363 m_expand_body may speculatively expand forms in the wrong
1364 environments. Made argument number checks conditional on
1367 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1369 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1372 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1373 changing their argument forms. Since m_expand_body
1374 speculatively macro expands forms the process must be
1377 (m_ident_eqp): Fixed to use proper environment.
1379 (renamed_ident): Added DEFER_INTS_EGC.
1381 Added prototypes for static functions.
1387 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1388 is false, do not produce an error for unbound variables, return a
1389 pointer to cell_undef instead.
1391 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1395 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1396 destructively changing their argument forms. Since m_expand_body
1397 speculatively macro expands forms the process must be reversible.
1399 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1400 SCM_IM_LET introduced by named lets.
1402 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1404 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1405 scm_letrec. scm_letrec1 does not check for a null binding and
1406 takes an additional argument to specify the ISYM of the body. Use
1407 scm_m_body instead of bodycheck.
1409 (scm_m_let): Use scm_m_body instead of bodycheck.
1411 (scm_m_expand_body, scm_macroexp): New.
1413 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1415 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1416 check=1. Throw error for internal defined that have not been
1417 rewritten by scm_m_expand_body.
1419 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1420 Removed prototype for SCM_APPLY.
1422 * tags.h: Added extern declaration of scm_isymnames.
1424 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1426 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1428 * lang.c: New file: Beginning of multi-language support.
1430 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1432 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1433 (scm_dynamic_wind): Added argument checking for the after guard so
1434 that we don't add garbage on the dynwind chain.
1435 (scm_swap_bindings): Added.
1437 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1438 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1439 (scm_isymnames): New isyms for multi-language support.
1441 * eval.c (scm_nil, scm_t): New symbols.
1442 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1443 forms for multi-language support.
1445 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1447 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1449 Renamed functions in the random function library interface
1450 from scm_i_XXX --> scm_c_XXX.
1452 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1454 * ports.c (scm_putc): fix line-buffering.
1456 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1458 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1459 scm_set_ptob_XXX --> scm_set_port_XXX.
1461 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1463 * ports.c, ports.h (scm_make_port_type): New interface for
1464 creation of port types (replaces scm_newptob). Just as for the
1465 smobs, we need to separate the internal representation of smob
1466 types from the interface, so that we easily can add new fields and
1467 rearrange things without caring about backward compatibility.
1468 This change was forced by the need in GOOPS to create classes
1469 representing port types.
1470 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1471 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1472 scm_set_ptob_seek, scm_set_ptob_truncate,
1473 scm_set_ptob_input_waiting_p): New setters.
1474 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1476 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1477 (scm_prinport): Removed.
1478 (scm_port_print): Added.
1479 (scm_print_port_mode): Added.
1480 (void_port_ptob, print_void_port, close_void_port, noop0):
1481 Removed. Removed #include "genio.h" Added #include "objects.h",
1484 * fports.c (prinfport): Moved code from ports.c.
1485 (local_free): Added.
1486 (scm_fptob): Removed. Instead use new interface.
1487 (scm_make_fptob): Added. (Need to create basic ports in a
1488 specific order in ports.c.)
1490 * strports.c (scm_stptob, prinstpt, noop0): Removed
1491 (scm_make_stptob): Added.
1493 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1494 (scm_make_sfport): Added.
1496 * filesys.c (scm_dir_print): Don't use the port printing code.
1497 Instead provide specific directory printer.
1499 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1501 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1502 scm_ptob_descriptor.
1504 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1505 Removed #include "genio.h"
1507 * objects.c (scm_make_port_classes): New function ptr.
1509 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1511 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1513 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1514 allow the 1st argument to be a fdes or filename as well as a
1515 port (as in the filesys.c version).
1517 * filesys.c (scm_truncate_file): removed.
1519 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1521 * readline.c, readline.h: Removed.
1523 * objects.c, objects.h (scm_port_class): Added.
1524 (scm_class_of): Look up port class in scm_port_class.
1525 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1526 SCM_INOUT_PCLASS_INDEX): Added.
1529 * Makefile.am: Removed genio.c, genio.x.
1533 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1535 * init.c: Make sure that scm_post_boot_init_modules is called only
1536 once. (Important when using a dumped image.; Thanks to Bernard
1539 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1541 * guardians.c (scm_guardian_zombify): Separate scanning for
1542 zombies from marking the pairs of the free list.
1544 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1545 use the macros. (Thanks to Michael Livshin.)
1547 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1548 lambda. Let your sins be purified by the blood of the lambda.
1549 (Thanks to Eric Hanchrow.)
1551 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1552 (Thanks to Valdis Kletnieks.)
1554 Fixes for EMX from Mikael Ståldal.
1556 * filesys.c: #include <io.h>, if we have it.
1557 * scmconfig.h.in: Regenerated.
1559 * stime.c (ftime): Delete declaration for this function --- let
1560 the system supply it.
1562 Cleanups from John Bley.
1564 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1566 * gsubr.c: Don't include "gsubr.h" twice.
1568 Cleanups for compilation on Irix 6, from David Kaelbling.
1570 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1571 regex_t pointer. This is what the callers have, mostly.
1572 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1573 scm_regexp_error_msg.
1575 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1576 int. That way, if we get a warning on this line, it's more likely
1577 that we're really missing bits we care about.
1579 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1582 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1583 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1584 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1585 cast at all is more appropriate in every case. At the moment, we
1586 assume everywhere that SCM is an integral type anyway.
1588 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1590 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1591 read_pos after scm_fill_buffer.
1593 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1596 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1597 fports.c (fport_fill_buffer): implement the interface change.
1599 * ports.c (scm_fill_buffer): interface change: no longer increments
1600 read_pos past the character that's returned. it seems clearer to
1601 leave it to the caller to decide what to do (thanks Jim).
1603 * vports.c (sf_fill_buffer): put the read char into the buffer
1604 as well as returning it.
1606 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1618 * strports.c (st_seek): change the resize checks.
1620 * ports.c (scm_ftruncate): throw error if offset works out negative.
1622 * strports.c (st_flush): increase string size in blocks of

1624 it's greater and reset read_buf_size.
1625 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1626 to be maintained for output ports too (it holds the written
1627 part of the string, while write_buf may have unwritten buffer
1629 (st_truncate): rewritten.
1630 (top of file): added a few notes.
1632 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1634 Patch from Greg Badros:
1635 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1636 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1637 (function pointer) argument to scm_make_gsubr and scm_make_subr
1638 calls. This avoids warnings in C++ programs using guile-snarf.
1640 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1642 * strports.c (st_grow_port): set pt->read_pos. set
1643 pt->read_buf_size one less than pt->write_buf_size if there's
1644 an unwritten char at the end of the string. similarly for
1646 (st_resize_port): renamed from st_grow_port.
1647 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1648 seek from read_end instead of write_end for SEEK_END.
1649 (st_ftruncate): calculate current length using readbuf, not write
1651 (scm_strport_to_string): use read_buf_size for length.
1652 (stfill_buffer): don't re-initialise the readbuf.
1654 1999-07-05 Gary Houston <ghouston@easynet.co.uk>

1667 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1668 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1669 and "bigneg" smob types.
1671 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1672 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1675 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1676 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1677 SCM_NEWCELL and setting the CAR/CDR by hand.

1761 trinary conditional in order for the flag computation to be
1764 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1766 * struct.c, struct.h:
1768 In order to support different kinds of deallocation, a destructor
1769 slot has been added to struct vtables. This allows for structs
1770 containing pointers to other memory blocks.
1772 (scm_struct_i_free): New hidden struct slot. Holds destructor for

1786 scm_struct_i_size which holds the size of light structs.
1787 (scm_struct_i_n_words): This slot has changed meaning. Previously

1841 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1843 Patch from Greg Harvey:
1844 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1845 around the condition of an `if', `while', etc., even if the
1846 condition is a macro invocation that expands to something
1847 surrounded by parens. It's more readable.
1849 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1850 proper lists, and of the appropriate lengths.
1851 (check_map_args): New function. (Thanks to Greg Harvey for the
1854 1999-06-19 Michael Livshin <mike@olan.com>

1873 (scm_igc): Check for underflow by seeing if this is negative.
1875 * gc.h (scm_mallocated): Fix declaration.
1876 (Thanks to Greg Harvey.)
1878 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.
1880 1999-06-15 Jim Blandy <jimb@savonarola.red-bean.com>
1882 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1883 sbd_time. (Thanks to Eric Hanchrow.)
1885 Fix from Ken Raeburn <raeburn@raeburn.org>:

1887 vector contents, to be used only during garbage collection.
1888 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1889 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1891 (scm_weak_size, scm_n_weak): Deleted.
1892 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1893 vectors without allocating new storage during GC, using
1894 scm_weak_vectors as the head of the chain.
1895 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1896 instead of stepping through an array.
1897 (scm_gc_sweep): Update offset used to find start of weak vector to
1899 (scm_init_storage): Set scm_weak_vectors to EOL.
1901 Fix from Ken Raeburn <raeburn@raeburn.org>:
1902 * gc.c (already_in_gc): New variable.
1903 (scm_igc): Set and clear already_in_gc; abort if it's set at
1906 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1908 Fix from Gary Houston:
1909 * fports.c (local_seek): Signal an error if the seek fails.
1910 * ports.c (scm_lseek): Don't check return value of port's seek
1911 function; it's its job to signal an error if there's a problem.
1913 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1915 * strports.c (scm_call_with_output_string): Don't include the

1920 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1921 scmsigs.c, strports.c, vports.c: Install the sources which
1922 actually correspond to the changes described below. I got the
1923 ChangeLog entries and the patch from two different places...
1925 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1927 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1928 it shows up as terrible performance, as we GC constantly.
1930 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1931 newline. A bit faster, and definitely hairier.
1932 (scm_read_line): Count newlines here instead.
1934 * strings.c (scm_take_str): New function.
1935 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1936 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1937 scm_take_str, to avoid copying the string.
1939 Add some simple-minded support for line buffered ports.
1940 * ports.h (SCM_BUFLINE): New flag for ports.
1941 * init.c (scm_init_standard_ports): Request line-buffering on
1942 the standard output port.
1943 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1945 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1946 and there's a newline to be written, flush the port.
1948 Gary Houston's open-buffer port patches:
1950 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1952 * ports.c: (scm_lseek): clear buffers even if just reading current
1955 * fports.c (local_fclose): call local_fflush unconditionally.

1963 strports.c (scm_mkstrport): check that pos is reasonable.
1964 ioext.c (scm_ftell, scm_fseek): use lseek.
1965 (SCM_CLEAR_BUFFERS): macro deleted.

1967 ports.h (scm_ptobfuns): add ftruncate.
1968 ports.c (scm_newptob): set ftruncate.
1970 ports.c (scm_ftruncate): new procedure.
1971 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1972 strports.c (st_seek, st_grow_port): new procs.
1973 fports.h (scm_port): change size types from int to off_t.
1974 ports.c (scm_init_ports): initialise the seek symbols here
1975 instead of in ioext.c.
1976 strports.c (scm_call_with_output_string): start with an empty
1977 string, so seek and ftruncate can be used.
1979 gdbint.c: adjust string port usage.
1981 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1983 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1984 equivalent to fflush for the read buffer.
1985 * ports.c (scm_newptob): set read_flush.
1986 ports.c (void_port_ptob): set read_flush.
1987 fports.c (local_read_flush): new proc. add to ptob.
1988 strport.c (st_read_flush): likewise.
1989 vport.c (sf_read_flush): likewise.
1990 fports.h (struct scm_fport): remove random member. there's nothing
1991 left but fdes. leaving it as a struct to allow for future changes.
1992 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1993 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1994 ptob proc if the read buffer is filled.
1996 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1998 * ports.h (scm_port): add a rw_random member and replace
1999 reading and writing members with rw_active member.
2000 SCM_PORT_READ/SCM_PORT_WRITE: new values.
2002 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
2004 * ports.h (struct scm_port_table): add writing and reading members
2005 to replace write_needs_seek: it isn't good enough for non-fports.
2006 ports.c, ioext.c, fports.c: corresponding changes.
2007 (struct scm_port_table): give it a typedef and rename to scm_port.
2008 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
2009 corresponding changes.
2011 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
2013 * ports.c (scm_newptob): bugfix: set seek member.
2014 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
2015 and generalised to all port types.
2017 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
2019 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
2020 signals (it was only being done for handlers installed from Scheme).
2021 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
2022 waiting for input caused an EINTR error from read.
2024 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
2026 * ports.h (struct scm_port_table): make all the char members
2027 unsigned, so they convert to int without becoming negative if large.
2029 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
2031 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
2032 with threads enabled. rename this procedure to
2033 fport_wait_for_input and take a port instead of a fdes.
2034 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
2036 * readline.c (scm_readline): Applied a patch from Greg Harvey to
2037 get readline support working again: use fdopen to get FILE objects.
2039 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
2041 * gc.c (scm_init_storage): install an atexit proc to flush the
2043 (cleanup): the new proc. it sets a global variable which can be
2044 checked by the ptob flush procs to avoid trying to throw
2045 exceptions during exit. not very pleasant but it seems more reliable.
2046 * fports.c (local_fflush): check terminating variable and if set
2047 don't throw exception.
2048 * CHECKME: that the atexit proc is installed if unexec used.
2050 * throw.c (scm_handle_by_message): don't flush all ports here.
2051 it still causes bus errors.
2053 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
2054 and move to ioext.c.
2056 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
2058 * ports.c (scm_char_ready_p): check the port buffer and call the
2059 ptob entry if needed.
2061 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
2062 ptob initialisers. use it in char-ready
2064 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
2066 * vports.c (sfflush): modified to write a char (since softports
2067 currently use shortbuf.)
2069 * fports.c (scm_standard_stream_to_port): moved to init.c and
2072 * init.c (scm_init_standard_ports): make stdout and stderr
2073 unbuffered if connected to a terminal. with stdio they
2074 were line-buffered by default.
2076 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
2079 * ports.h (scm_ptobfuns): change fflush return to void.
2080 change flush proc definitions.
2082 * strports.c (scm_call_with_output_string): get size from
2083 buffer instead of port stream.
2084 (st_flush): new proc.
2086 * ports.h (struct scm_port_table): added write_end member,
2087 as an optimisation. set it where write_buf_size is set.
2089 * ports.h (struct scm_port_table): change stream from void *
2090 back to SCM. SCM presumably must be large enough to hold a
2091 pointer (and probably vice versa but who knows.)

2464 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2466 Most of this batch of changes is about how to deal with extended
2467 types when an object system is loaded into Guile. A nice object
2468 system is capable of representing Guile's types as class objects.
2470 For example, we want a regular expression to be of class <regex>.
2471 But regular expressions are smobs which aren't under direct
2472 control of the object system, so there has to be some mechanism
2473 which informs the object system that a new class should be created
2474 which can represent the smob type. I call this a "wrapper class".
2476 * objects.c: #include "smob.h";
2477 (scm_class_keyword): Removed. (Class is automatically created by
2479 (scm_smob_class): Array of smob classes indexed by smobnum.
2480 (scm_make_extended_class): "Plugin" function pointer for creation
2481 of wrapper classes for smob and struct types.
2482 (scm_class_of): Handle compiled closures. (Currently regarded as
2484 Use scm_smob_class to handle smob types;
2485 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2486 through scm_smob_class;
2489 * smob.c (scm_newsmob): Also create a wrapper class if
2490 scm_smob_class has been initialized.
2492 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2493 type code and smobnum.
2495 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2496 (scm_struct_table): Weak key table with auxilliary information for
2497 struct types. Currently used for names and wrapper classes.
2498 (scm_struct_ihashq): Hash function for structs.
2499 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2500 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2501 for accessing names of vtables. The record implementation in
2502 boot-9.scm currently uses the setter to record the name of record
2503 types. When the object system is initialized, it can use this
2504 information to create wrapper classes with suitable names.
2505 (scm_init_struct): Allocate scm_struct_table.
2506 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2507 (struct tags are a finite resource and we might want to restrict
2508 the use of tags to vtables only. E.g., Goops only uses tags for
2510 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2512 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2515 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2516 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2517 Used for access of struct table entries.
2519 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2520 (scm_hash_fold): New procedure. Used to process all entries in a
2521 hash table (in no particular order).
2523 Argh! For the umpteenth time I got compilation errors because of
2524 the "intuitive" name `kw'. This has to have an end:
2526 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2527 "kw" --> "keywords" everywhere.
2528 (I doubt that this will cause big compatibility problems since the
2529 application interface is unaffected.)
2531 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2533 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2535 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2536 column inums to native form.
2538 Improvement of backtraces: Introduces a new stack narrowing
2539 specifier, #t, for the inner cut. (See further in the comments in
2540 stacks.c:narrow_stack ().)

2543 (Used to flag certain system procedures which shouldn't turn up in
2546 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2547 modules which aren't "user" modules and the code of which
2548 shouldn't turn up in backtraces.)

2551 Extract the lookup closure from an environment.
2552 (scm_system_module_env_p): New function: Return non-#f if MODULE
2555 * stacks.c: #include "eval.h"; #include "procprop.h";
2556 (narrow_stack): Handle new narrowing specifier #t.
2558 * debug.c (scm_procedure_name): Use name property in the default
2561 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2563 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2565 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2566 procedure throughout.
2568 * print.c (scm_iprin1): Removed extraneous space when printing
2569 procedure-with-setters.
2571 Entity and operator setter slots were introduced as a complement
2572 to the <procedure-with-setter> type in order to support entities
2573 and operators with setters in a reasonable and efficient way.
2574 * procs.c (scm_procedure, scm_setter): Handle entity and operator
2577 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

2587 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2589 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
2590 directly through the instance.
2592 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2594 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2595 scm_struct_i_flags instead of scm_vtable_index_layout!

2618 Readline paren matching from Greg Harvey, with modifications from
2621 * readline.c (in_readline, reentry_barrier_mutex): Make these
2624 * readline.c: #include <sys/time.h> and "iselect.h", so we can
2625 control how long we're paused, and threads will run while we're
2627 (match_paren, find_matching_paren, init_bouncing_parens): New
2629 (scm_init_readline): Call init_bouncing_parens.

2680 SYMB now point to const.
2682 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2684 * print.c (scm_iprin1): Use scm_procedure_name instead of
2685 scm_procedure_property for compiled closures.
2687 * tags.h (scm_tc7_pws): New procedure type. Four representations
2688 for procedure-with-setters were considered before selecting this
2691 1. A closure where the CODE and ENV slots are used to represent
2692 the getter and a new SETTER slot is used for the setter. The
2693 original getter is stored as a `getter' procedure property. For
2694 closure getters, the CODE and ENV slots contains a copy of the
2695 getter's CODE and ENV slots. For subr getters, the CODE contains
2698 2. A compiled closure with a call to the getter in the cclo
2699 procedure. The getter and setter are stored in slots 1 and 2.
2701 3. An entity (i.e. a struct with an associated procedure) with a
2702 call to the getter in the entity procedure and the setter stored
2703 in slot 0. The original getter is stored in slot 1.
2705 4. A new primitive procedure type supported in the evaluator. The
2706 getter and setter are stored in a GETTER and SETTER slot. A call
2707 to this procedure type results in a retrieval of the getter and a
2708 jump back to the correct eval dispatcher.
2710 Representation 4 was selected because of efficiency and
2713 Rep 1 has the advantage that there is zero penalty for closure
2714 getters, but primitive getters will get considerable overhead
2715 because the procedure-with-getter will be a closure which calls
2718 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2719 <procedure-with-setter>, but together with rep 2 it suffers from a
2720 three level dispatch for non-GOOPS getters:
2722 cclo/struct --> dispatch proc --> getter
2724 This is because the dispatch procedure must take an extra initial
2725 argument (cclo for rep 2, struct for rep 3).
2727 Rep 4 has the single disadvantage that it uses up one tc7 type
2728 code, but the plan for uniform vectors will very likely free tc7
2729 codes, so this is probably no big problem. Also note that the
2730 GETTER and SETTER slots can live directly on the heap, using the
2731 new four-word cells.
2733 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2734 SCM_SETTER): New macros.

2813 * random.c: Removed alloca includes.
2815 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2817 * Makefile.in: This changed, for some reason I don't really
2818 understand, when I ran automake in the top level directory. This
2819 may be contamination by Cygnus internal releases. If you re-run
2820 automake and this change gets reverted, don't worry about it.

2850 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2851 scm_get_one_zombie, scm_init_guardian): This is an implementation
2852 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2853 David Eby (1993) "Guardians in a Generation-Based Garbage
2854 Collector" ACM SIGPLAN Conference on Programming Language Design
2855 and Implementation, June 1993 ftp://ftp.cs.indiana.edu

2866 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2868 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2871 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2873 Move the procedure slots of entities to invisible slots (so that
2874 we can have operator class objects which themselves are entities).
2875 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2876 SCM_STRUCTF_ENTITY): New constants.
2878 * struct.c (scm_make_struct): Allocate "invisible" room for
2879 procedures if SCM_STRUCTF_ENTITY is set in vtable.

2889 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2891 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2893 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2894 of syntactic forms, similar to SCM_PROC.
2895 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2896 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2897 for the name symbols when needed.
2899 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2901 * Makefile.in: Regenerated.
2903 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2905 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2906 take the address of _into; it might be a register. Just have
2907 scm_debug_newcell return the new cell.
2908 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2909 taking the address of a place to store it as an argument.
2910 * gc.h (scm_debug_newcell): Change declaration.
2911 (Thanks to Greg Harvey.)
2913 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2926 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2928 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2929 error if no source properties can be found for a frame. (Thanks
2930 to Christian Lynbech.)
2932 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2934 * objects.h: Removed slots direct_supers and direct_slots from the
2935 definitions of the rudimentary classes described by objects.h.
2937 * objects.c, objects.h (scm_entity_p): New procedure. Together
2938 with the predicates scm_procedure_p and scm_struct_p, this
2939 predicate makes it possible to differ between structs, entities
2942 * modules.c, modules.h (scm_resolve_module): New function.
2944 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2946 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2947 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2950 * objects.c (scm_entity_p): New procedure.

2955 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2957 * procprop.h (scm_i_procedure_arity): Added declaration.
2959 * procprop.c (scm_i_procedure_arity): Made global; New code to
2960 handle operators and entities.
2961 (scm_procedure_property): No need to call scm_procedure_p since
2962 scm_i_procedure_arity now does all necessary type checking.
2963 Added #include "objects.h".
2965 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2966 s_add_hook_x --> s_remove_hook_x.
2967 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.

2971 (scm_make_hook): Optional argument defines number of arguments to
2973 (scm_make_named_hook): Take number of args as second arg.
2974 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2975 boot-9.scm for a while); First arg is the hook. The rest are
2976 arguments passed on to the hook procedures.
2978 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2980 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2981 scm_logbit_p): Do the computation in ulongs. This is not as nice
2982 as doing it in bignums, but at least it's good enough for
2983 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2985 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2986 subexpressions. (Thanks to Charbel Jacquin.)
2988 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2990 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2991 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2992 (scm_make_named_hook): New function.
2994 * feature.c: Added #include "eval.h".
2996 * modules.c (scm_make_module): Beautify the module.
2998 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3000 * modules.c, modules.h: New files: C interface to modules. (This
3001 is necessary in order to interface the object system to Guile
3002 properly. The guts of these modules will be replaced by the new
3003 module system in the future.)
3005 * init.c: Added #include "modules.h"
3006 (scm_boot_guile_1): Call scm_init_modules.
3007 (invoke_main_func): Call scm_post_boot_init_modules.
3009 * Makefile.am: Added modules.c, modules.x, modules.h.
3011 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
3013 * procs.c: #include "objects.h"
3014 (scm_procedure_p): Return #t also on structs which are operators.
3016 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
3017 <operator-metaclass> and <entity-class> to <standard-class>,
3018 <operator-class> and <entity> in order to conform with STKlos
3021 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
3022 which isn't an operator.
3023 (SCM_APPLY): Ditto, but jump to badproc.
3025 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
3027 * eval.c (SCM_CEVAL): Allow structs implanted in code.
3028 Previously, structs implanted in code were interpreted as forms
3029 the operator of which was a gloc. We solve this by checking for
3030 the zero in the emulated vcell in the struct vtable. Since
3031 implanted structs always will look like forms with a gloc
3032 operator, execution will only be slowed down by maximally one
3033 extra test-and-branch per application.
3035 * evalext.c (scm_definedp): Removed check for isyms; Added a
3036 second optional argument: It is now possible to supply an
3037 evaluation environment in which to look for the symbol.
3039 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3041 * readline.c (scm_init_readline): Set
3042 rl_basic_word_break_characters. (Thanks to Ian Grant.)
3044 * coop.c (coop_condition_variable_wait): Removed
3045 (coop_condition_variable_wait_mutex): Folded logic of
3046 coop_mutex_unlock into coop_condition_variable_wait_mutex to
3047 prevent condvar signal lossage. Previously, another thread could
3048 start to run after unlocking the mutex but before putting the
3049 current thread on the wait queue. If that thread then would
3050 signal the first, the signal would be lost. (Thanks to Christian
3053 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3055 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
3058 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3060 * objects.c (scm_i_make_class_object): Renamed from
3061 make_class_object; exported; error checking moved to
3062 scm_make_class_object and scm_make_subclass_object.
3063 (scm_make_class_object, scm_make_subclass_object): Use
3064 scm_i_make_class_object.
3065 (scm_make_subclass_object): Let the subclass have same metaclass
3068 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3070 * debug.c (scm_debug_options): Bugfix: Set the value of
3071 scm_stack_checking_enabled_p after setting debug options;
3072 #include "stackchk.h". (Thanks to Richard Polton.)
3074 1998-11-13 Radey Shouman <rshouman@metro2000.com>
3076 * unif.c (scm_array_contents): removed unnecessary test for 0
3079 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3081 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
3082 Replaced by macro `collect' in boot-9.scm.
3084 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3086 * eval.c (scm_copy_tree): Copy source properties if existent.
3088 * debug.c (scm_start_stack): Copy source when evaluating. (If we
3089 don't, we may end up passing memoized source to a transformer.)
3091 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3093 * stack.c (get_applybody): Help function which lookups the first
3094 body form of the apply closure.
3095 (read_frames): Prevent the source of the first form of the apply
3096 closure from being recorded. This would only be confusing.
3098 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
3099 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
3101 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
3103 * stacks.c (read_frame): Bugfix: Removed lingering `else'
3105 (read_frames): Use SCM_MACROEXPP.
3107 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3109 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
3110 don't contain interesting information since all arguments are
3111 present in the frame which applies the compiled closure anyway.);
3112 Skip the transformer application frames.
3114 * print.c (scm_iprin1): Print gsubrs as primitives.
3116 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3118 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
3120 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
3121 that we can identify these in a backtrace. (This change doesn't
3122 introduce any significant speed penalty.)
3124 * eval.c: Added note about `serial-map' using scm_map.
3126 * read.c, read.h (scm_read_options, scm_read_opts): Removed
3127 readline options. They should reside in their own options array.
3129 * readline.c, readline.h (scm_readline_options,
3130 scm_readline_opts): Moved readline options here.
3132 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3134 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
3135 SCM_ROCHARS instead of SCM_CHARS.
3137 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
3138 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
3140 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3142 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
3143 This is quite important since the latter clears the
3144 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
3145 every single character read...
3147 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3149 * print.c (scm_iprin1): Removed suspect looking (and indeed
3150 malevolent) semicolon after test for user supplied closure print
3151 procedure. (Thanks to Telford Tendys.)
3153 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
3154 (scm_memq, scm_memv, scm_member): Do argument checking *before*
3155 starting to search the list. Removed call to sloppy_mem_check.
3157 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
3158 procedures: Same as scm_delq_x et al, but delete maximally one
3161 * options.c (scm_options, scm_init_options): GC-protect option
3162 values of type SCM. (Thanks to Telford Tendys.)
3164 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3166 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
3167 make sure that there always is a "real" scm_lookupcar.
3169 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3171 * read.c, read.h (scm_read_opts): New read options
3172 "history-length" and "history-file".
3173 (scm_read_options): Stifle history to history length.
3175 * readline.c (scm_read_history, scm_write_history): New procedures.
3177 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3179 * eval.h (scm_macro_eval_x): Removed declaration.
3181 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
3182 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
3183 Renamed and made global.
3185 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
3186 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
3188 * evalext.c, evalext.h: New files. Contain non-R5RS things
3189 having to do with evaluation.
3191 * evalext.c (scm_serial_map): New procedure: Version of `map'
3192 which guarantees that the procedure is applied to the lists in
3194 (scm_m_sequence_to_list): New syntax: Version of `begin' which
3195 returns a list of the results of the body forms instead of the
3196 result of the last body form.
3197 (scm_definedp, scm_m_undefine): Moved from eval.c
3199 * evalext.h (scm_m_sequence_to_list): Added declaration.
3201 * macros.c, macros.h: New files.
3202 (scm_procedure_to_syntax, scm_procedure_to_macro,
3203 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
3204 scm_macro_name, scm_macro_transformer): Moved from eval.c
3205 (scm_make_synt): Moved from eval.c
3207 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
3209 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
3212 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
3214 * debug.c, print.c: Added #include "macros.h".
3216 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3218 This change adds the ability to use `unread-char' multiple times
3219 without interspersed reads and adds the new procedure
3220 `unread-string'. The change is optimized for the common case of
3221 unreading a single character. This is also the reason behind the
3222 choice to store characters in the port itself: in most cases no
3223 extra malloc is required.
3225 The amount of code in some macros in ports.h has been increased to
3226 the extent that they would fit better as C functions, but, since
3227 this code belongs to the port representation, such functions
3228 should be placed in ports.c which would cause calls back and forth
3229 between ports.c and genio.c. That is not good for performance.
3230 Also, keeping them as macros allows the compiler to do some
3231 optimizations which are needed to make the current interface
3232 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
3234 One benchmark (Guile startup time) indicates an increase of
3235 loading speed of 1%. Another (reading (using `read') boot-9.scm
3236 10 times) shows no change in performance.
3238 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
3239 made to find a beautiful solution.)
3241 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
3242 (SCM_TRY_CLRDY): New macro: Only clear the first unread
3243 character. (SCM_CLRDY clears all.)
3244 (SCM_N_READY_CHARS): New macro: Returns number of unread
3245 characters in a port. Returns wrong answer if SCM_CRDYP is false.
3246 (struct scm_port_table): New fields: `entry' contains port table
3247 index, `cp' points to last unread char, `cbuf' is the buffer for
3248 unread chars, `cbufend' points after end of the character buffer.
3250 * ports.h, ports.c (scm_unread_string): New procedure.
3251 (scm_grow_port_cbuf): New function.
3253 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
3255 (scm_generic_fgets), fports.c (local_fgets): Use a loop
3256 to read unread characters. Use SCM_TRY_CLRDY instead of
3259 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
3261 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
3263 * genio.c, genio.h (scm_ungets): New function.
3265 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
3268 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3270 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
3271 declarations. (Thanks to Russ McManus.)
3273 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3275 * numbers.c (num2long): As a software archeologist, I'm proud of
3276 this finding! :) Preliminary dating suggests an almost 4 year old
3277 remnant from the SCM ancestor. The sample has been removed from
3278 the finding site and is now safely stored in the repository.
3280 * numbers.h: Removed prototype for num2long.
3282 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
3284 * gh_data.c (gh_scm2doubles): Make it possible to pass result
3285 array as second arg.
3286 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
3287 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
3288 * gh.h: Updated and added prototypes.
3290 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
3292 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
3294 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
3296 * guile-snarf.in: Never generate an empty file. (Thanks to
3299 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
3300 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
3301 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
3302 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
3303 gh_new_procedure5_0): Specify argument types, to appease C++
3304 compilers. (Thanks to Brad Bowman.)
3306 Bug reports from Russ McManus:
3307 * guile-snarf.in: If the CPP environment variable is set, use that
3308 as the C preprocessor, instead of the preprocessor autoconf
3310 * snarf.h (SCM_PROC): Cast the function pointer passed to
3311 scm_make_gsubr, to satisfy C++.
3313 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
3314 Use the handler passed, instead of ignoring it and using
3315 gh_standard_handler. (Thanks to Etienne Bernard.)
3317 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
3319 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
3322 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

3339 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
3342 * script.c (scm_compile_shell_switches): Define
3343 use-emacs-interface in the root module, so the repl code can see
3344 it. See today's change to top-repl in ice-9/boot-9.scm.
3346 * filesys.c (set_element, get_element): Make sure that `element'
3347 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3348 Boekemeier and Jorgen "forcer" Schaefer.)
3350 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3352 * chars.c (scm_charnames): In ASCII character name table, make
3353 newlines print as #\newline by default, not #\nl.
3355 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3356 alphabetical order. Oh thrills. But it helps me know how far
3357 along in the compilation I am.
3358 * Makefile.in: Regenerated.
3360 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3362 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3363 #bytes(...) to #y(...), and syntax for short vectors from
3364 #short(...) to #h(...). This may seem nutty, but, like the other
3365 uniform vectors, byte vectors and short vectors want to have the
3366 same print and read syntax (and, more basic, want to have read
3367 syntax!). Changing the read syntax to use multiple characters
3368 after the hash sign breaks with the conventions used in R5RS and
3369 the conventions used for the other uniform vectors. It also
3370 introduces complexity in the current reader, both on the C and
3371 Scheme levels. (The Right solution is probably to change the
3372 syntax and prototypes for uniform vectors entirely.)
3374 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3376 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3377 (Thanks to Jorgen "forcer" Schaefer.)
3378 * ports.h (SCM_NOFTELL): New flag.
3379 * fports.c (local_fgets): If it's set, use the generic fgets.
3380 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3382 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3384 * script.c (scm_compile_shell_switches): Add handling of -q switch
3385 (inhibit loading of user init file).
3386 (scm_shell_usage): Add usage text for -q switch.
3387 (scm_compile_shell_switches): Always load user init file first if
3388 it is loaded at all.
3390 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3392 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3393 and is now broken under NetBSD. I can't fathom what it's trying
3394 to do, so I've replaced it with something that I do understand,
3395 which seems to work, and which isn't broken on NetBSD. "Progress?
3396 You Decide." (Thanks to Perry Metzger.)
3398 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3399 signed/unsigned comparison.
3401 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3403 Warning fixes from Greg Harvey:
3404 * unif.c (scm_array_set_x): initializer for pos
3405 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3406 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3407 initializers for field_type, since EGCS so desparately wants to
3409 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3410 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3411 when GUILE_DEBUG is defined.
3412 * dynwind.h (scm_wind_chain): Same.
3413 * ports.h (scm_pt_size, scm_pt_member): Same.
3414 * print.h (scm_current_pstate): Same.
3415 * procs.h (scm_make_cclo): Same.
3417 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3419 Handle short and long long uniform arrays properly. (Thanks to
3421 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3422 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3423 scm_tc7_llvect (long long vectors).
3425 Change the way libguile and boot-9.scm are timestamped, to try to
3426 get rid of these spurious mismatch warnings. Now both
3427 libguile/versiondat.h and ice-9/version.scm are generated directly
3428 by the configuration process, rather than having version.scm
3429 generated directly, and libguile/versiondat.h generated by the
3430 Makefile, which is generated by configure. It seems that
3431 sometimes the Makefile would change, but versiondat.h depends on
3432 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3433 * Makefile.am (versiondat.h): Target removed; this is generated
3434 directly by the configure script now.
3435 (BUILT_SOURCES): Remove versiondat.h.
3436 * versiondat.h.in: New file, transformed by the configure script
3438 * Makefile.in: Regenerated.
3440 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3441 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3442 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3443 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3444 if we want to use them in a header file some day, we can. (Thanks
3445 to Michael Livshin.)
3447 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3448 SCM numbers, so we won't have rollover problems; the range of a
3449 signed long in milliseconds is about 25 days. (Thanks to Karl
3452 Don't redefine sleep and usleep; fix this problem now.
3453 * coop.c (sleep, usleep): Remove declarations; we don't use or
3454 redefine these any more.
3455 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3456 job of usleep and sleep in a thread-friendly way. We can use
3457 these in the rest of Guile. Define versions for systems both with
3458 and without iselect.
3459 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3460 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3461 we're just using it, not redefining it, we can use a K&R style
3463 (sleep): Declare this, too, if the system hasn't.
3464 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3465 scm_uthread_sleep if they're available; otherwise, just call the
3467 * scmconfig.h.in: Regenerated.
3469 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3471 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3473 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3475 * threads.c: Doc fix.
3477 The argument type of usleep varies from system to system,
3478 as does the return type. We really shouldn't be redefining usleep
3479 at all, but I don't have time to clean that up before the 1.3.
3480 release. It's on the schedule for afterwards. (Thanks to Julian
3482 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3484 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3485 * scmconfig.h: Regenerated.
3487 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3488 right way to handle system variation. Autoconf's approach is the
3490 * simpos.h (scm_software_type): Declaration deleted.
3492 * script.c (scm_find_executable): Don't test if unix is #defined
3493 here; first, NetBSD doesn't #define it, and second, it's the wrong
3494 way to go about these things. (Thanks to Perry Metzger.)
3495 (dld_find_executable): Delete this MSDOS support code. This isn't
3496 the way we want to support this; it needs to be rethunk at a
3499 * genio.c (scm_do_read_line): Don't just politely check that the
3500 line was either non-empty or EOF. Abort if it's empty and not
3503 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3505 * scmconfig.h.in: Regenerated.
3507 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3510 * genio.c (scm_do_read_line): Count lines correctly when the file
3511 doesn't end in a newline.
3513 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3515 * genio.c (scm_do_read_line): Maintain the line count correctly.
3516 (Thanks to Harvey J. Stein and Greg Harvey.)
3518 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3521 * numbers.c (big2str): Protect t from garbage collection until
3522 we're done. (Thanks to Gary Houston.)
3524 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3526 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3528 * Makefile.in: Regenerated.
3530 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3531 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3534 Do magic to mix reads and writes on stdio FILE-based ports.
3535 (Thanks to Christian Lynbech.)
3536 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3538 (pre_read, pre_write): New functions.
3539 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3540 local_fputs): Call them.
3541 (local_fflush): Mark the port as ready for reading and writing.
3542 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3543 flags on new port objects. This might not be accurate --- who
3544 knows what state the FILE * is in when we get it --- but it won't
3545 do extraneous calls to fflush or fseek, so it's no worse than the
3546 behavior before this change.
3547 * ports.h: Add comment.
3549 Centralize the creation of port objects based on stdio FILE * in
3550 fports.c; don't just throw them together anywhere.
3551 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3552 what the rest of Guile wants. Don't set the revealed count;
3553 that's only appropriate for stdin, stdout, stderr.
3554 (scm_standard_stream_to_port): This function does set the revealed
3556 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3557 not scm_stdio_to_port.
3558 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3559 * fports.c (scm_open_file): Same.
3560 * posix.c (scm_pipe): Same.
3561 * socket.c (scm_sock_fd_to_port): Same.
3562 * ioext.c (scm_fdopen): Same.
3563 (scm_freopen): Moved from here to...
3564 * fports.c (scm_freopen): ... here. This is really something that
3565 munges the internals of an fport, so it should go here.
3566 * fports.h (scm_stdio_to_port): Adjust prototype.
3567 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3568 * ioext.h (scm_freopen): Prototype removed.
3570 * filesys.c (set_element, get_element): This can work on both pipe
3571 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3574 * scmconfig.h.in: Regenerated.
3576 Change the definition of the functions in scm_ptobfuns so that
3577 they get passed the port object, not the port's stream.
3578 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3579 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3580 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3581 Pass the port itself to the scm_ptobs function.
3582 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3583 scm_generic_fgets): Same.
3584 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3585 getc_void_port, fgets_void_port, close_void_port): Just change the
3586 argument names; these functions don't really do anything.
3587 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3588 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3589 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3590 Also, use prototyped definitions, and get rid of the extra
3592 (scm_fptob, scm_pipob): We don't need casts here any more.
3593 * strports.c (prinstpt): Use prototype declarations.
3594 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3595 and use SCM_STREAM to get the string info. Also, use prototyped
3596 definitions, and get rid of the extra declarations.
3597 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3600 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3601 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3603 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3604 scm_fgets, for consistency.
3605 (scm_fptop, scm_pipob): References updated.
3607 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3609 Include the source location in error messages for scripts.
3610 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3611 stack is still there when we catch the error.
3612 * throw.c (handler_message): If we are handling an error with a
3613 message, then put together the proper arguments and call
3614 scm_display_error, instead of scm_display_error_message. That
3615 displays source location, if it can find it.
3617 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3619 * gc.c (scm_unprotect_object): Change this so that calls to
3620 scm_protect_object and scm_unprotect_object nest properly.
3621 (scm_protect_object): Doc fixes.
3623 * strings.c (scm_string_set_x): Require the argument to be a
3624 writable string, not a substring or a symbol.
3625 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3626 (Thanks to John Redford and Charbel Jacquin.)
3628 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3630 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3632 * eval.c (safe_setjmp): Remove this misunderstanding.
3633 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3636 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3638 * libguile.h: Mark these as C declarations, for compilation by C++
3641 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3642 __cplusplus clause. I seriously doubt this ever worked the way
3643 the author seems to have intended.
3645 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3647 Utterly needless cleanups to hopelessly messy code.
3648 * ports.c: Doc fixes.
3649 (scm_fflush): Moved to ...
3650 * genio.c (scm_fflush): ... here, amongst all the other port
3651 method invocation functions.
3652 * genio.h, ports.h: The prototype moves too.
3654 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3656 * backtrace.c (display_error_body): The current frame does not
3657 always have a parent frame; consider a function called directly
3658 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3661 * alloca.c (alloca): Undo yesterday's changes, and simply call
3662 malloc directly for storage, and abort if we don't get what we
3663 want. The situation is much simpler --- just call malloc. Emacs
3664 has bizarre/evil requirements (signal handlers might malloc unless
3665 you set this global flag, so you have to set the flag around all
3666 calls to malloc) which we are certainly not going to conform to,
3667 so we can do the simple and obvious thing.
3669 * coop.c (coop_condition_variable_wait): Make this function
3670 static. It's only useful internally --- you should never just
3671 wait on a condition variable.
3672 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3674 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3676 * unif.c (scm_array_set_x): Accept any kind of number as an
3677 element for a uniform vector of doubles. This is more consistent
3678 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3680 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3681 works; I can't conveniently test it myself. (Thanks to Dvid
3682 Tillman for the bug report.)
3684 * init.c: Doc fixes.
3686 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3687 from here, not from scm_compile_shell_switches (which is a pretty
3688 dumb place to do it).
3689 (scm_load_startup_files): New function.
3690 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3691 * script.c (scm_compile_shell_switches): Don't load the startup
3693 (scm_ice_9_already_loaded): Variable moved.
3694 * init.c (scm_load_startup_files): Prototype for new function.
3695 * gh_init.c (gh_enter): Doc fix.
3697 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3699 Some anti-warning changes from Greg Harvey.
3700 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3701 warnings when it doesn't understand our NORETURN declarations in
3703 * posix.c (scm_mknod): Similar.
3705 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3707 * posix.c (scm_getpwuid): If we can't find an entry, return our
3708 own message, instead of using scm_syserror --- the getpwMUMBLE
3709 functions don't set `errno' to anything interesting.
3711 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3713 Get rid of warnings from the cooperative threading system.
3714 * threads.h (scm_single_thread_p, scm_yield,
3715 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3716 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3717 scm_wait_condition_variable, scm_signal_condition_variable): Add
3718 prototypes for these Scheme-visible functions.
3719 * coop-defs.h (coop_next_runnable_thread,
3720 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3721 Prototypes for these here, even though they're from iselect.c.
3722 (coop_condition_variable_wait, coop_join): Add prototypes.
3723 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3724 scm_threads_free_condvar): Make these smob functions static.
3725 * coop-threads.h (coop_init): Give this a real prototype.
3726 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3727 (coop_next_runnable_thread): No need to provide prototype; it's in
3730 * scmconfig.h.in: .detarenegeR
3732 * iselect.c, threads.c: Doc fixes.
3734 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3736 * Makefile.in: Regenerated with a patched automake, to get
3737 dependency generation right when using EGCS.
3739 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3740 warning. (Thanks to Robert Pluim.)
3742 * inet_aton.c (inet_aton): Reassure the compiler that the
3743 arguments to the <ctype.h> macros are all unsigned characters, not
3746 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3748 Getting rid of more warnings...
3749 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3750 today's change to ../configure.in.
3751 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3752 * scmconfig.h.in: Regenertaded.de.,.__
3753 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3754 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3757 * readline.c: Doc fix.
3758 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3759 * readline.h (scm_filename_completion_function): Add prototype.
3760 (scm_init_readline): Make this into a prototype.
3762 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3763 declare this, instead of calling scm_make_subr manually.
3765 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3767 * readline.h (scm_init_readline): Add prototype for this.
3768 (scm_init_readline): Make this a real prototype.
3770 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3772 Warning fixes from Maciej Stachowiak:
3773 * backtrace.h (scm_display_application, scm_backtrace): Add
3775 * debug.c (scm_m_start_stack): Make this function static.
3776 * fluids.h (scm_fluid_p): Add prototype.
3777 * procprop.c (scm_i_procedure_arity): Make this function static.
3778 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3779 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3780 * root.h (scm_dynamic_root): Add external prototype.
3781 * scmsigs.h (scm_usleep): Add external prototype.
3782 * script.h (scm_init_script): Use prototype, not K&R decl.
3783 * stacks.h (scm_stack_id): Add external prototype.
3784 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3786 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3788 * gh.h: took out the definitions of vset and vref, since they are
3789 replaced by the proper vector routines that correspond to the R4RS
3792 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3794 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3795 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3796 third argument, a C expression that should result in a SCM value,
3797 which is used to initialize the variable. Reimplemented
3798 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3801 * version.h (scm_libguile_config_stamp): Add prototype.
3802 (From Maciej Stachowiak.)
3804 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3806 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3807 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3809 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3811 * print.c (scm_iprin1): Rather than having one i, and using it in
3812 several places, declare a fresh i local to each block where it is
3813 used, and give it a signedness appropriate to its use in each case.
3814 (scm_iprlist): Same.
3816 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3817 comparison warnings.
3819 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3820 signed/unsigned clashes.
3822 * posix.h (scm_tmpnam): Added prototype.
3824 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3825 scm_make_subclass_object): Add external prototypes.
3827 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3828 comparison is okay here.
3830 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3832 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3833 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3835 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3838 * load.c (swap_port): Make this function static.
3840 * load.c (scm_search_path): Make max_path_len and max_ext_len
3841 unsigned, since they're compared against string sizes.
3843 * load.c (init_build_info): Make i unsigned.
3845 * ioext.h (scm_read_line): Add prototype.
3847 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3848 scm_hash_fn_remove_x): Make hash bucket index local variable k
3849 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3850 accurately as possible.
3852 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3853 comparisons, and range checking to make sure those casts are
3856 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3857 signed/unsigned comparisons.
3859 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3860 avoid signed/unsigned comparisons.
3861 * smob.h (scm_numsmob): Change extern declaration to match.
3863 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3864 avoid signed/unsigned comparisons.
3865 * ports.h (scm_numptob): Change extern declaration to match.
3866 (scm_current_load_port, scm_set_port_line_x,
3867 scm_set_port_column_x): New prototypes.
3869 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3870 test code, and it causes warnings.
3872 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3873 gh_uniform_vector_ref): Added prototypes.
3875 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3876 debugging support unconditionally. That's backtrace.c, stack.c,
3877 debug.c, and srcprop.c.
3878 (EXTRA_libguile_la_SOURCES): Omit those from here.
3879 * Makefile.in: Regenerated.
3881 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3883 * options.c (scm_options): Bugfix: Allow empty list of options!
3885 * debug.c, debug.h (scm_single_step): Removed.
3886 (scm_with_traps): New procedure. This procedure could easily be
3887 written in Scheme but needs to be highly optimized.
3889 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3891 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3892 Check SCM_TRAPS_P before trapping.
3894 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3896 Changes to avoid signed/unsigned comparison warnings.
3897 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3898 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3899 so they can have appropriate types for each application. Make i
3900 signed. Use initializers in some spots. I'll probably pay for
3902 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3903 (scm_must_realloc): Make nm unsigned.
3904 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3905 (scm_init_storage): Use prototype-style definition, and make the
3907 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3908 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3910 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3911 avoid signed/unsigned comparison warnings, and because the return
3912 value of readlink may be -1. Don't bother casting the third
3913 argument to readlink.
3915 * filesys.c (scm_dirname, scm_basename): Move these to their own
3916 page, at the end of the file.
3917 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3919 * eval.h (scm_eval_options_interface): Add external prototype for this.
3920 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3922 * eval.c (scm_lookupcar1): Make this static.
3924 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3925 Make these prototype declarations, not K&R-style.
3927 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3928 unsigned comparison warning.
3930 * appinit.c: File removed. It had a single function in it, empty,
3931 whose reason for existence is explained in no documentation or
3932 comment. I think it's there as a default for some Tcl-style
3933 initialization, but Tcl abandoned that approach a while ago.
3934 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3935 (BUILT_SOURCES): Remove appinit.x.
3936 * Makefile.in: Regenerated.
3938 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3940 * Makefile.in: Regenerated using the last public version of
3941 automake, not the hacked Cygnus version.
3943 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3945 Remove Totoro kludge.
3946 * Makefile.in, scmconfig.h.in: Regenerated.
3947 * init.c, readline.c: Don't check if TOTORO is #defined.
3949 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3951 * Makefile.am: Adjust for new thread configuration system.
3952 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3953 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3955 (THREAD_LIBS): Definition deleted; automake will generate such
3956 things automatically.
3957 * Makefile.in: Regenerated.
3959 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3961 Simplify smob and port marking; set the mark bit in the generic
3962 marking code, and make marker routines only responsible for
3963 turning up outgoing pointers.
3964 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3965 before calling the marking function. Don't call the marking
3966 function if it's zero.
3967 * markers.c (scm_mark0): Just return #f. This function isn't
3968 necessary at all now, but it's harmless to call it. We'll leave
3969 it in so other folks' code doesn't croak at link time.
3970 (scm_markcdr): Don't call SCM_SETGC8MARK.
3971 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3972 * dynl.c (mark_dynl_obj): Same.
3973 * root.c (mark_root): Same.
3974 * srcprop.c (marksrcprops): Same.
3975 * unif.c (markra): Same.
3976 * variable.c (scm_markvar): Same.
3977 * ports.c (scm_markstream): Same.
3978 (void_port_ptob): Specify zero for our marking function.
3979 * debug.c (debugobjsmob): Same.
3980 * dynwind.c (guardsmob): Same.
3981 * filesys.c (dir_smob): Same.
3982 * fluids.c (fluid_smob): Same.
3983 * fports.c (scm_fptob, scm_pipob): Same.
3984 * mallocs.c (mallocsmob): Same.
3985 * regex-posix.c (regex_t_smob): Same.
3986 * smob.c (freecell, flob, bigob): Same.
3987 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3988 * throw.c (jbsmob, lazy_catch_funs): Same.
3990 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3992 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3993 scm_copy_tree on code in order not to let memoized code to leak
3994 out. Thus, scm_copy_tree needs to copy vectors as well since
3995 quasiquote can introduce evaluated code also inside vector
3998 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4000 * eval.c (scm_copy_tree): Removed ability to copy vectors.
4002 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
4003 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
4006 * unif.c: Say that ivect and uvect are of type signed and unsigned
4007 long instead of int in commentary so that it correctly describes
4010 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4012 * stime.c: Removed declaration of strptime. (It should be
4013 declared by the system headers. If it turns out that some systems
4014 don't, we'll handle that then.) (Thanks to Greg Troxel.)
4016 * stime.h: Renamed TIMEH --> STIMEH
4018 * backtrace.c (scm_display_error, scm_display_backtrace): In order
4019 to increase portability, don't use structure assignment.
4020 (Thanks to Nicolas Neuss.)
4022 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
4024 (finalize_fd_sets): Added empty statement after last case label.
4025 (Thanks to Nicolas Neuss.)
4027 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
4030 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
4032 * init.c, readline.c: OK, I won't have these readline.x bug
4033 reports anymore. We've had them since April. The current reason
4034 is a completely unintelligible failure of totoro.red-bean.com to
4035 do the test for rl_getc_function in libreadline correctly. This
4036 kludge overrides the test if we're on totoro so that the snapshot
4037 generation process can work.
4039 * readline.c: Define a strdup replacement if not existent on system.
4041 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4043 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
4044 This change makes scm_make_vector R5RS compatible. We cannot keep
4045 the third argument since people want to be able to deduce the form
4046 of the C function call only by looking at R5RS. (At the same time
4047 we have removed some unnecessary complexity!)
4049 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
4050 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
4051 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
4052 argument in call to scm_make_vector.
4054 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4056 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
4057 This macro is useful in applications.
4059 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4061 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
4062 (scm_parse_path, scm_search_path): New Scheme level procedures.
4064 * load.h (scm_internal_parse_path, scm_parse_path,
4065 scm_search_path): Declared.
4067 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4069 * filesys.c (dirname, basename): New procedures.
4071 * init.c (scm_boot_guile_1): Removed condition around
4074 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
4075 new data type (guards) for representation of C level guards and
4076 data on the wind chain.
4077 (scm_internal_dynamic_wind): New function.
4079 * dynwind.h: Declare scm_internal_dynamic_wind.
4081 * root.h (scm_root_state): Added scm_cur_loadp.
4083 * root.c (mark_root): Added comment about cur_loadp.

4089 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
4091 * ports.c (current-load-port): New procedure.
4093 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4095 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
4096 not a tty, return #f.
4098 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
4099 to Julian Satchell and Roland Kaufmann.)
4101 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
4102 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
4104 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4106 * debug.h, debug.c (scm_start_stack): New function. Implements
4107 the guts of old scm_m_start_stack.
4109 * debug.c (scm_m_start_stack): Use scm_start_stack.
4111 * init.c (scm_start_stack, scm_restart_stack): Renamed to
4112 start_stack and restart_stack. (These have static scope.)
4114 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4116 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
4117 readline functions to come in release 2.3. (Thanks to Chet
4119 (handle_errors): Use the above functions.
4121 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4123 * readline.c: Improvements for readline support: Handle errors
4124 better; Implement before-read-hook.
4126 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4128 * init.c (scm_boot_guile_1), readline.c: Test for
4129 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
4130 assure that we have version >= 2.1.)
4132 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
4134 * readline.c (scm_readline): Defer interrupts while we're calling
4137 * readline.c (scm_add_history): Bugfix: Do strdup before giving
4138 away the string to add_history.
4139 (completion_function): Do completion for readline. (Thanks to
4141 (scm_filename_completion_function): New procedure: Filename
4143 (current_input_getc): New function. Use this one instead of
4144 standard getc from readline.
4146 * throw.c, throw.h (scm_handle_by_throw): New function: This
4147 handler throws errors to next handler on the dynwind chain.
4149 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
4151 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
4154 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4156 * procprop.c (scm_i_procedure_arity): New function. Returns arity
4158 (scm_procedure_properties): Modified to return arity together with
4160 (scm_procedure_property): Added the read-only property `arity'.
4161 (scm_set_procedure_property_x): It is an error to set the `arity'
4164 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
4165 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
4167 * procprop.h (scm_sym_arity): New symbol.
4169 * objects.c (scm_set_object_procedure_x): New procedure: Use this
4170 to set the dispatch procedure of an operator or entity object.
4172 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
4173 Made procedure slots read-only.
4175 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
4176 scm_tcs_cons_gloc case in zero args switch; Fixed args
4177 construction for operators in scm_tcs_cons_gloc case in two args
4180 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4182 * fluids.c: Removed use of assert.h (in order to avoid
4185 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
4187 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
4189 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
4190 change makes the evaluator safer at the cost of evaluation speed.
4191 It handles the case when the user has added a non-immediate
4192 improper end of the application form, e.g., `(+ 0 . x)'.
4193 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
4194 minimize the extra cost as much as possible. The new code is
4195 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
4196 problem with structs planted directly in the code (e.g. by a
4197 macro). This no longer causes segmentation fault. (Thanks to
4200 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
4201 arg `proc' in order to be able to throw errors; New argument
4204 * Removed extra #include "debug.h"
4206 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
4208 * scmsigs.c: Declare usleep as returning void on some systems.
4209 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
4212 * coop.c (usleep): Return void on some systems.
4214 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4216 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
4218 * coop.c: Changed return type of usleep to int.
4220 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
4221 isn't found in the OS.
4223 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
4224 isn't enabled. (Thought that I had made this change ages ago...)
4226 * iselect.c: Declare bzero if not defined by OS.
4228 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4230 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
4231 condition. (Thanks to John Tobey.)
4233 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
4234 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
4237 * __scm.h: Start the long-term project of moving to POSIX threads.
4238 Phase 1: Classification of all critical sections.
4239 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
4240 for A sections. (See comments in __scm.h for details.)
4242 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
4243 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
4245 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4247 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
4248 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
4249 (libpath.h, versiondat.h): Replaced dependency on Makefile with
4250 dependencies on $(srcdir)/Makefile.in
4251 $(top_builddir)/config.status in order to avoid circularity.
4253 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
4254 from argc if argc was 0 initially.
4256 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
4257 in generation of libpath.h.
4259 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
4261 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
4262 libguile from 2 to 3.
4264 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
4266 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
4268 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
4270 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
4271 scm_set_port_column_x, scm_port_filename,
4272 scm_set_port_filename_x): Removed optional arguments. Added
4273 proper argument checking.
4275 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
4276 stack size in machine words.
4278 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
4279 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
4280 to Ole Myren Röhne.)
4282 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
4284 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
4285 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
4287 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
4290 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
4291 procedure apply: Copy argument lists before pushing them unto the
4292 environment so that the environment won't get mutated due to
4293 manipulation of procedure arguments. This should perhaps be
4294 regarded as a temporary solution until someone finds a more
4295 efficient one. (Thanks to Maciej Stachowiak.)
4297 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
4299 * script.c (scm_compile_shell_switches): Use "guile" as default
4300 zero arg if argc is NULL.
4302 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
4304 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
4305 is zero. (Thanks to Dirk Herrmann.)
4307 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
4309 * ports.c (scm_add_to_port_table): First line is now line 0
4310 (was 1). (Interface changed according to suggestion by Per
4313 * backtrace.c (display_header): Add 1 to line and column numbers
4314 when presenting them to the user.
4316 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
4317 from debug.c --> eval.c
4319 * eval.h, eval.c (scm_eval_options_interface): New options
4321 (SCM_EVAL_STACK): New option: Size of newly created stacks,
4322 i.e. stacks for new threads.
4324 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
4326 * eval.c (unsafe_setjmp): Removed with #if 0.
4328 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
4331 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
4332 to avoid compiler warnings.
4334 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
4336 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
4338 * throw.c (handler_message): Print message on current error port
4339 instead of default error port. (Thanks to Maciej Stachowiak.)
4341 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
4343 * ports.c (scm_add_to_port_table): allocate in units of
4344 struct scm_port_table *, not struct scm_port_table.
4345 * posix.c (scm_close_pipe): remove the port from the port table
4347 Thanks to Rob Engle for both fixes.
4349 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4351 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4352 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4354 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4356 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4358 * backtrace.c (display_error_body, display_backtrace_body),
4359 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4360 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4361 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4362 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4365 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4366 don't receive the jmpbuf arg anylonger.
4367 (scm_catch): Don't accept a #f tag.
4368 (scm_throw): Check that key is a symbol.
4369 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4371 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4373 * async.c (async_pending): Removed declaration.
4375 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4377 * dynwind.c (scm_wind_chain): New debug function.
4379 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4380 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4381 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4382 extra layer of functions around the body and handler of a thread.
4383 This extra layer makes sure that the handler is called in the
4384 dynamic context of the surround (= empty dynwind list), but under
4385 the *dynamic root* of the body. We can not use the dynamic root
4386 of the surround since that root belongs to another thread => stack
4387 is not handled correctly. It may seem ugly to use this extra
4388 layer, but the extra cost in terms of execution time is really
4389 negligible compared to the total amount of time required to create
4390 a thread, and it would reduce maintainability to duplicate the
4391 crucial and complicated steps performed by cwdr.
4393 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4394 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4395 get re-enabled. The important effect of this is that interrupts
4396 are blocked during thread switching so that thread data structures
4397 don't risk getting messed up by an unfortunate signal.
4398 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4399 seems to do more aggressive optimization which actually move
4400 instructions around in these macros in a fatal way. Therefore:
4401 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4402 just superstitious...)
4403 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4404 This macro should be used instead of SCM_ASYNC_TICK since the
4405 latter doesn't do context switches any more.
4407 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4408 instead of SCM_ASYNC_TICK.
4410 * coop.c, iselect.c: Since thread switches are now performed with
4411 interrupts masked, we can't use the old mechanism of delivering
4412 signals immediately when they arrive. Signals must instead be
4413 delivered when the asyncs run *after* the end of the critical
4414 section in scm_internal_select. But this also means after context
4415 switch so that the signal will be delivered to a different thread.
4416 To avoid this, I have changed the protocol of
4417 coop_wait_for_runnable_thread and friends so that they are allowed
4418 to return the original thread. So, if a signal arrives during
4419 scm_internal_select, we won't any longer be forced do a context
4420 switch, but can remain in the same thread and deliver the signal
4423 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4424 scm_asyncs_pending and made it global.
4426 * iselect.c: Small fixes.
4428 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4429 coop_condition_variable_init, coop_condition_variable_wait,
4430 coop_condition_variable_signal): Changed return type from `void'
4431 to `int'. This is to adhere closer to the pthreads interface.
4432 This, in turn, is part of an attempt to provide C versions of the
4433 mutex and condition variable primitives which can be part of a
4434 frontend to COOP or pthreads.
4436 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4437 coop_condition_variable_destroy): New functions.
4439 * coop-threads.c (scm_wait_condition_variable): Use
4440 coop_condition_variable_wait_mutex.
4442 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4443 Definitions moved to coop-defs.h.
4445 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4446 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4447 scm_cond_destroy): New C interface to mutecis and cond vars.
4449 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4451 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4453 * iselect.c: Now several threads can wait on the same file
4454 descriptor. The behaviour is compatible with OS select: All
4455 threads waiting for the fd return with the same status.
4457 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4459 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4460 Can spawn a thread from application C code.
4462 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4464 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4465 gh_doubles2scm): New functions.
4467 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4469 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4470 commented-out version of gh_eval_str()
4472 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4474 * socket.c (scm_bind): free soka after use.
4476 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4478 * stime.c (tzvar): new variable.
4479 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4480 avoid memory leaks when allocating.
4482 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4484 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4487 * gc.c, tags.h: Doc fixes.
4489 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4491 * eval.c (macro-eval!): Removed. This function was a design bug.
4492 It allowed memoized code to leak out to the scheme level. Most
4493 things that you could do with `macro-eval!' can be done with
4496 1997-12-20 Tim Pierce <twp@skepsis.com>
4498 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4499 scm_fgets now depends on ftell(3) to know how many bytes were
4502 1997-12-15 Tim Pierce <twp@skepsis.com>
4504 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4505 dealing with strings.
4507 1997-12-13 Tim Pierce <twp@skepsis.com>
4509 Make %read-line more suitable for implementing read-line efficiently.
4510 * ioext.c (scm_read_line): Strip the terminating newline from a
4511 string, and return a cons of the string and its terminator.
4513 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4514 of the string that is read is stored in this memory location.
4515 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4516 * genio.c, genio.h (scm_do_read_line): Update caller.
4517 * ports.h (scm_ptobfuns): Update typedef.
4518 * fports.c (scm_fptob, scm_pipob): Update struct.
4520 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4522 * filesys.c (set_element): Return file descriptor.
4523 (fill_select_type): Return the highest file descriptor.
4524 (scm_select): Tell select about the highest file descriptor. On
4525 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4526 Therefore the extra overhead for calculating the maximum fd seems
4527 to be more than compensated. Is this correct? In any case,
4528 scm_internal_select will be much faster with this info.
4529 (scm_select, fill_select_type, set_element): Don't accept any kind
4530 of object in the file descriptor list or vector.
4532 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4534 * iselect.c (finalize_fd_sets): Bugfix.
4536 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4538 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4539 when using scm_internal_select (since we might switch to another
4542 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4544 * simpos.c (scm_system): always define: use sysmissing if not
4545 available. Check for HAVE_SYSTEM instead of _Windows (does
4546 Windows lack system or does it have an unusable one?).
4547 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4548 Let the argument be optional: if not supplied, call system(NULL).
4550 * ports.c (scm_close_port): relax the type check from OPPORTP to
4551 PORTP; closing a closed port is allowed.
4553 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4555 * fports.c (scm_fgets): Return if the last char in a chunk is
4556 newline. When fgets returns a string whose length is `size-1', it
4557 is ambiguous whether a whole line was retrieved, so we must check
4558 explicitly whether a line terminator is present.
4560 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4562 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair

4643 replacement in iselect.c.
4644 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4645 coop_join): If GUILE_ISELECT enabled, use
4646 coop_wait_for_runnable_thread instead of
4647 coop_next_runnable_thread.
4648 (usleep, sleep): New replacements for system functions if
4649 GUILE_ISELECT is enabled.
4651 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4653 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

4668 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4669 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4670 and scm_must_free, since ultimately the string returned will be copied
4671 by scm_makfrom0str anyway. Also, read any characters that may have
4672 been pushed onto the port with scm_ungetc.
4673 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4674 * ioext.c (scm_read_line): Free string after Guilifying it.

4690 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4691 and to invoke scm_shell().
4692 (gh_launch_pad): took out the loading of boot-9.scm from here,
4693 since it is probably best to let the user control that. In fact,
4694 gh_repl() now invokes scm_shell() which does that.
4696 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4698 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4725 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

4733 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4735 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4736 OPORT is an `open' port, not an output port.

4745 scm_close_all_ports_except, scm_set_current_output_port,
4746 scm_set_current_error_port): Likewise
4747 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4748 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4762 exactly what we want to leave in to detect substrings.
4763 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4764 * tags.h: Fix diagrams and comments describing the S tag bit;
4765 remove vestigial remarks about the D tag bit.

4788 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4790 * gh_data.c (gh_vector_set_x): changed name to make it consistent

4819 * tags.h (scm_tc7_substring): Changed the comment and code to
4820 conform with the changes below. Folks! We have suddenly two new

4885 * gh_test_c.c (c_vector_test): some improvements on the vector
4888 * gh.h (gh_vector): this used to exist but do the wrong thing.
4889 Now it (almost) does the right thing, though it takes a list
4890 instead of the individual arguments. I need to see how it could
4892 (gh_list_to_vector): added this function as a macro. Corresponds
4893 to Scheme's (list->vector ...).

4901 (gh_make_vector): this used to be (stupidly) called gh_vector().
4902 This is the right name, since it does the same thing as the Scheme

4939 printing: Also output hex code of vtable so that type identity
4940 will be indicated as well.

4952 transformers. (They are always: exp env.); Bugfix: Unmemoize
4953 transformer source with correct environment.

4962 (cwdr_handler): New function.
4963 (scm_internal_cwdr): New function to perform the function of cwdr
4964 but take args that are more useful to C code. Also, the handler
4965 is now invoked *outside* of the new dynamic root, like the docs

4967 is responsible for using a handler that does not throw, if he
4969 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4970 * root.h (scm_internal_cwdr): New prototype.
4972 Even more but risky streamlining:
4974 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4975 allocation of the jumpbuf of a root continuation. The changes
4976 below are controlled by it. They are now deactivated.
4977 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4978 the JMPBUF of the scm_rootcont to NULL before returning.
4980 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4981 when they are non-NULL.

5002 one or when it returns #f.
5003 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
5004 Accept a port/print-state pair in addition to just a port.
5005 (scm_prin1): Don't return the print_state to the pool when it has
5007 (scm_printer_apply): Set `revealed' field of print_state to true.
5008 (scm_init_print): Set scm_print_state_vtable.

5018 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
5020 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
5021 was looping endlessly.
5023 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
5025 * strports.c (scm_eval_string): Don't close the port.
5027 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
5028 former returns a nice normal integer. (Thanks to Daniel
5031 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
5033 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
5034 makefile variable as a build parameter called LIBS. The
5035 build-guile program will use this, for the time being.
5036 * Makefile.in: Regenerated.
5038 Thanks to Shiro Kawai:
5039 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
5040 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
5043 * Makefile.in: Regenerated with automake 1.2a.
5045 * script.c (scm_compile_shell_switches): If we hit the -c or --
5046 arguments, don't set the car of (command-line) to scm_usage_name,
5047 the prettified name of the guile executable; give it the full
5048 path, the way shells usually handle $0.
5050 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5052 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
5053 Scheme-level name `array-map' and renamed `serial-array-map' to
5054 `serial-array-map!'.
5056 * backtrace.c: Introduced exception handlers which now enclose
5057 `display-error' and `display-backtrace' so that error reporting
5058 won't get into infinite loops if an error occurs during displaying
5059 of the error. This can very easily happen with user supplied
5060 print call-back routines.
5062 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5064 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
5065 the names `serial-array-map' and `array-map' should be removed.)
5067 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
5069 * init.c (scm_boot_guile_1): Added scm_init_objects ().
5070 Added #include "objects.h"
5072 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
5073 Add #include "feature.h".
5075 * Makefile.am (libguile_la_SOURCES): Added objects.c.
5076 (modinclude_HEADERS): Added objects.h.
5078 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
5079 This test is needed at many places in the code and should be
5080 abstracted. (Motivated by the need of this test in libguiletk.)
5082 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
5083 (scm_eval_string), load.c (scm_primitive_load,
5084 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
5085 Use SCM_EOF_OBJECT_P.
5087 * eval.c (scm_init_eval): Add feature `delay'.
5089 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5091 * scmhob.h: Removed.
5093 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5095 * list.h (SCM_LISTn): New macros. Make list creation in C code
5096 prettier. The idea comes from STk.
5098 * sequences.h, sequences.c, append.h, append.c: Removed. These
5099 files implemented non-R4RS operations which would encourage
5100 non-portable programming style and less easy-to-read code.
5102 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
5105 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
5106 sequences.h, #include append.h.
5108 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
5111 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
5113 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
5115 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
5117 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5119 * eval.c: Added #include "objects.h"
5121 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
5124 * smob.c (scm_smob_prehistory): Create two objectsmobs with
5125 adjacent smob numbers.
5127 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5129 * procprop.h: Added declaration of scm_i_inner_name.
5131 * gsubr.c: New global symbol scm_i_inner_name.
5133 * debug.c (scm_procedure_name): Try procedure property
5134 `inner-name' if `name' fails.
5136 * print.c (scm_iprin1): Use scm_macro_name.
5138 * eval.c (scm_m_define): Give names to macros as well; Only the
5139 first top-level definition gives a procedure/macro a name.
5140 Otherwise confusing names can turn up in backtraces.
5141 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
5142 `name'; Give names to macros as well.
5144 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
5145 (scm_macro_transformer): Use SCM_CLOSUREP instead of
5148 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5150 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
5152 (prinmacro): Removed. The code has been moved/merged into print.c
5153 in order to decrease code redundancy. We want macros to print in
5154 a way equivalent to procedures, and it would be silly to duplicate
5155 the required code. (We don't want to maintain two places.)
5156 (macrosmob): Print field is now a NULL pointer.
5158 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
5159 scm_macro_transformer): New prototypes.
5160 (scm_tc16_macro): Declared.
5162 * print.c (scm_iprin1): Added code for printing of macros. Macros
5163 are now printed in a way equivalent to procedures.
5165 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
5167 * procs.h (scm_closure_p): Added declaration.
5169 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5171 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
5172 Shouldn't pass "heap" as the subr name.
5174 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
5176 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
5177 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
5178 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
5179 gh_equal_p): Use SCM_NFALSEP, instead of testing against
5180 SCM_BOOL_T. Any non-false value is true.
5182 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5184 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
5185 scm_gensym): Added prototypes.
5187 * symbols.c (scm_gensym): New function. This will speed up
5188 certain types of applications (such as macro systems) which
5189 generate lots of symbols.
5191 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5193 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
5195 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
5197 * unif.c (scm_shap2ra): tighten the checking of the array dimension
5198 specifier, since (2) or (2 . 3) would cause SEGV.
5199 (scm_transpose_array): more argument checking fixes.
5201 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
5203 * Makefile.in: Regenerated.
5205 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
5207 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
5209 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5211 * error.c, error.h (scm_error_callback): Removed (see NEWS).
5213 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
5215 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
5216 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
5219 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
5220 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
5221 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
5222 scm_array_p, scm_array_rank, scm_array_dimensions,
5223 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
5224 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
5225 scm_array_prototype): Added case scm_tc7_wvect.
5227 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
5229 * errno.h: prototype for scm_strerror.
5230 * error.c (scm_strerror): new procedure.
5232 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5234 * list.c (scm_list_append_x): Allow non-pair as last argument.
5235 This is consistent with the R4RS append and is probably the
5236 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
5238 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5240 * stime.h: prototype for scm_times.
5241 * stime.c (scm_times): new procedure.
5242 * ioext.c (scm_fseek): if the first argument is a file descriptor
5244 (scm_ftell): if the first argument is a file descriptor call lseek
5246 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
5247 * filesys.c (scm_chmod): if the first argument is a file descriptor,
5249 (scm_chown): if the first argument is a port or file descriptor,
5251 (scm_truncate_file): new procedure.
5252 Add DEFER/ALLOW INTS to a few other procedures.
5253 (scm_fsync): new procedure.
5254 (scm_open_fdes): new procedure.
5255 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
5257 (scm_fcntl): the first argument can now be a file descriptor. The
5258 third argument is now optional.
5260 * posix.c (scm_execl, scm_execlp): make the filename argument
5261 compulsory, since omitting it causes SEGV.
5262 (scm_sync): return unspecified instead of #f.
5263 (scm_execle): new procedure.
5264 (environ_list_to_c): new procedure.
5265 (scm_environ): use environ_list_to_c. disable interrupts.
5266 (scm_convert_exec_args): take pos and subr arguments and
5267 improve error checking.
5269 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5271 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
5272 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
5273 argument to SCM_ASSERT. Furthermore, the name of the function
5274 should be passed as first argument when signalling
5275 SCM_WNA. (Thanks to Thomas Morgan)
5277 * gsubr.c (scm_gsubr_apply): From Radey Shouman
5278 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
5279 dispatches on the number of actual args has a default case
5280 reporting an internal error. This is a vestige from a version
5281 that mallocated a SCM vector to hold the arguments. In the
5282 current version this check is too late: if it ever happens we will
5283 have already overstepped the bounds of the array.
5285 Also, the patch [...] adds a check for too many actual arguments."
5287 mdj: Removed check for "internal programming error".
5289 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5291 * gh_io.c (gh_write): New function.
5293 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
5294 throw.c (scm_internal_stack_catch): New sibling to the other catch
5295 functions. Code moved from gh_eval.c.
5296 throw.h: Added header.
5297 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
5298 scm_internal_stack_catch.
5300 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5302 * ioext.h: fix up prototypes.
5303 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
5304 Scheme name is now dup->fdes.
5305 (scm_dup_to_fdes): make the second argument optional and
5306 fold in the functionality of scm_primitive_dup.
5307 (scm_primitive_dup): deleted.
5309 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5311 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
5312 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
5313 ultrix are defined. Use setvbuf instead of setbuf.
5314 (scm_setvbuf): new procedure.
5315 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
5316 (scm_setfileno): moved from ioext.c.
5317 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
5318 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
5320 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5322 * fluids.c (scm_fluid_p): New function.
5323 * fluids.h (scm_fluid_p): New prototype.

5327 * print.c (scm_iprin1): Enter printed structures into the print
5328 state as nested data while they are printed.
5329 (print_state_fluid, print_state_fluid_num): New variables.
5330 (scm_init_print): Initialize them.
5331 (scm_iprin): If print_state_fluid carries a print_state, use that
5332 instead of creating a new one.
5333 (scm_printer_apply, apply_stub, struct apply_data): New
5334 definitions to help with calling printer functions written in
5336 * print.h (scm_printer_apply): New prototype.
5338 * struct.c (scm_print_struct): Use scm_printer_apply to call the
5339 user defined struct printer.
5341 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
5342 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

5347 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
5349 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5350 SCM_ASSERT: arg comes before pos.
5352 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5354 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5355 to a list of length zero correctly.
5357 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5359 Supply an `fgets' method for port objects to do fast line i/o.
5360 * ioext.c (scm_read_line): New function.
5361 * genio.c (scm_gen_read_line): New function.
5362 * fports.c (scm_fgets): New function.
5363 (scm_fptob, scm_pipob): Add scm_fgets method.

5371 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5373 * ioext.h: removed scm_duplicate_port prototype.
5375 * ioext.c (scm_primitive_dup2): return the new file descriptor
5376 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5378 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5379 stream has been set.
5380 (scm_duplicate_port): deleted, there's now an implementation in
5382 (scm_primitive_dup2): do nothing if newfd == oldfd.
5384 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5386 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5389 * ioext.h: new prototypes.
5390 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5392 * fluids.c (next_fluid_num): don't do
5393 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5395 * ports.h: prototypes too.
5396 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5398 * fports.h: prototype too.
5399 * fports.c (scm_evict_ports): moved from ioext.c.
5401 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5403 * ports.c (scm_close_port): return a boolean instead of unspecified.
5404 throw an error if an error other than EBADF occurs.
5406 * filesys.h: scm_close prototype.
5407 * filesys.c (scm_close): new procedure, can close file descriptors
5408 and ports (scsh compatible).
5410 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5413 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5415 * fluids.c, fluid.h: New files.
5416 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5417 (modinclude_HEADERS): Added "fluids.h"
5419 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
5420 scm_init_fluids to initialize the fluid machine.
5421 (scm_start_stack): Initialize the fluids of the first root with
5422 scm_make_initial_fluids.

5425 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5426 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5427 unique for the new root when it has a parent.
5429 * smob.h: Include "libguile/print.h" to make scm_print_state
5432 * dynl.c (free_dynl_obj): New function to free the dynamic object
5433 data. (dynl_smob): Use it.
5434 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5435 the dynamic object data below the linking of the object to avoid
5436 memory leak when the linking code throws an error. Now the code
5437 leaks a whole dynamically linked library when must_malloc throws,
5438 but that should be much less likely.
5440 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5442 Changes to compile under gnu-win32, from Marcus Daniels:
5443 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5444 (scm_localtime): Change SCM_EOF to SCM_EOL.
5445 (scm_mktime): Likewise.
5446 * socket.c: Don't include sys/un.h unless autoconf tells
5447 us Unix domain sockets are available.
5448 (scm_fill_sockaddr): Ignore Unix domain code.
5449 (scm_addr_vector): Likewise.
5450 (scm_init_addr_buffer): Likewise.
5451 (scm_socketpair): Don't include unless socketpair was

5454 * scmsigs.c (scm_pause): Don't include unless pause was found
5456 * posix.c (scm_getgroups): Don't include unless support function
5457 was found during autoconf (in this case, getgroups).
5458 (scm_setpwent): For setpwent.
5459 (scm_setegid): For setegid.
5460 * net_db.c (scm_inet_netof): Don't include unless support
5461 function was found during autoconf (in this case, inet_netof).
5462 (scm_lnaof): For inet_lnaof.
5463 (scm_inet_makeaddr): For inet_makeaddr.

5475 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5476 scm_misc_error, not SCM_EOF.
5478 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5479 arguments for formatting the error message, not SCM_BOOL_F. I
5480 think this is left over from the (eq? '() #f) days.
5482 * read.c (recsexpr): Give this a dummy definition if
5483 DEBUG_EXTENSIONS isn't #defined.
5485 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5487 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5490 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

5495 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5497 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5498 alloca.lo will be included in @LIBLOBJS@. Something better than
5499 this should be possible.
5500 * Makefile.in: Regenerated.
5502 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5504 * simpos.h: prototype for scm_primitive_exit.
5505 * simpos.c (scm_primitive_exit): new procedure, terminates the
5506 process without unwinding the stack.
5508 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5510 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5511 argument and logior its components together, so the user doesn't
5512 have to do this explicitly. Also, if regexp/basic is supplied, then
5513 turn off REG_EXTENDED.
5514 (scm_init_regex_posix): New regexp/basic symbol.
5515 (REG_BASIC): #define this if it is not already present.
5517 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5519 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5520 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5521 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5522 (DISTCLEANFILES): New target, clean *.x.
5523 * Makefile.in: Regenerated.

5527 * script.c (scm_compile_shell_switches): Add 1997 to copyright
5528 years in usage message.
5530 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5531 * Makefile.in: Regenerated.
5533 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5534 flag; I don't think we support it.
5535 (scm_make_regexp): Make sure the user doesn't pass the
5538 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5540 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5541 name them according to the SCSH convention: regexp/mumble.
5543 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5545 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5547 * Makefile.am (libpath.h): Include the values of all the standard
5548 Makefile directory variables. Print a message, but don't print
5550 (versiondat.h): Print a message, but don't print all the commands.
5551 * load.c: #include "alist.h".
5552 (init_build_info): New function.
5553 (scm_init_load): Call it.
5554 * Makefile.in: Regenerated.
5556 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5558 * root.c: Establish a reliable catch-all handler for the new root.
5559 After all the Scheme handler function might signal an error too,
5560 and we don't want to lose that.
5561 (cwdr_inner_body): Renamed from cwdr_body.
5562 (cwdr_outer_body): New function, to establish the user's handler,
5563 and pass control to cwdr_inner_body.
5564 (cwdr): Establish the reliable catch-all handler here, and pass
5565 control to cwdr_outer_body.
5566 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5567 the user's handler through to cwdr_outer_body.
5568 * throw.c (scm_handle_by_message): Move guts into....
5569 (handler_message): New static function.
5570 (scm_handle_by_message_noexit): New function.
5571 * throw.h (scm_handle_by_message_noexit): New prototype.
5573 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5574 across this. Only works on GCC. Otherwise, we hope for the best.
5575 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5576 the feeling that real thread systems will not need this...
5578 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5580 Try to detect when people are using one version of libguile and a
5581 different version of ice-9. People have been skewing things and
5582 sending in bug reports.
5583 * Makefile.am (versiondat.h): New file to generate.
5584 * version.c: #include "versiondat.h", to get version info.
5585 (scm_libguile_config_stamp): New function.
5586 * script.c: #include "version.h".
5587 (scm_compile_switches): Call scm_version to get version number.
5588 * scmconfig.h.in, Makefile.in: Regenerated.
5589 * Makefile.in: Regenerated.
5591 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5592 primitive definitions under their Scheme names.
5594 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5595 1:2. Helps avoid confusion between installed and uninstalled libs.
5597 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5600 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5601 backslash from definition; this should be used like: GDB_INTERFACE;
5603 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5605 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5606 new port unbuffered until its stream has been set.
5608 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5610 * ports.h: new prototype.
5611 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5613 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5615 Make things compile neatly under Sun's C compiler.
5616 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5617 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5618 unsigned, because that's what the ANSI function takes.
5619 * extchrs.h (xmbtowc): Corresponding change to prototype.
5620 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5622 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5623 argument plain char *.
5624 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5626 * tag.c (scm_tag): Remove unreachable statement.
5627 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5628 top of the word, it should be unsigned.
5630 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5631 is defined, to avoid warnings; it's only used in the
5632 conflict-checking code. Which might go away anyway.
5633 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5634 conditionals; put the label definition in an #if too, to stifle
5637 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5638 ChangeLog-threads in the distribution.
5639 * Makefile.in: Regenerated.
5641 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5643 * guile-snarf.in: Changed regexp to support CPPs that insert
5644 whitespace between lexical tokens (which munges the `%%%' snarf
5647 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5649 * load.c (scm_init_load_path): Append $(datadir)/guile to
5650 %load-path, so modules do not have to be installed in Guile's
5651 current version directory.
5653 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5655 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5656 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5657 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5658 call the sysdep functions with deferred ints.
5659 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5660 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5661 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5664 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5667 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5669 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5671 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5673 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5676 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5678 * eval.c (scm_lookupcar1): New procedure to cope with a race
5679 condition during lookup (when using threads).
5680 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5681 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5684 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5686 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5687 supplied. (Change from Tim Pierce.)
5689 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5691 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5692 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5693 default and not `()'. `#f' is the canonical non-value in Scheme,
5696 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5698 * struct.c (struct_printer): New variable that holds a handle on
5699 the Scheme variable *struct-printer*. This variable can be set by
5700 Scheme code to override the printing of structures.
5701 (scm_print_struct): If struct_printer is set, call it. If it is
5702 not set, or returns #f, print the structure in the old fashion.
5703 Include "eval.h" for scm_apply.
5705 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5707 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5708 scm_struct_i_n_words to get the number of fields, not
5709 -scm_struct_n_extra_words.
5711 On the route to fancier struct printing:
5712 * struct.c (scm_print_struct): New function to print a structure.
5713 Include "genio.h" to support it. This function doesn't do
5714 anything interesting right now, but I think it should be here
5716 * struct.h: Include "print.h" and add prototype for
5718 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5719 print structures ourself.
5721 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5723 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5724 before applying the handler in case it doesn't return.
5726 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5728 * scmsigs.h, async.h: updated.
5730 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5733 * posix.c (scm_uname): interpret only negative values as an error.
5734 Solaris normally returns a positive value.
5736 * script.c (scm_compile_shell_switches): if we are not going into
5737 an interactive repl, set scm_mask_ints to zero so that asyncs can
5740 * simpos.c (scm_system): don't ignore/unignore signals around
5743 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5746 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5747 done in boot-9.scm instead.
5749 * scmsigs.c, async.c: Major rewriting of signal handling code.
5750 (scm_sigaction): new procedure.
5751 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5753 (scm_raise): return unspecified, throw error on failure.
5755 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5757 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5758 feature, to help boot-9.scm decide whether to import the regex
5761 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5763 * eval.c: Include scmconfig.h at the beginning of the file so that
5764 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5767 * regex-posix.c: #include "_scm.h" before conditionally #including
5768 <regex.h>; the former defines HAVE_REGCOMP.
5770 * regex-posix.c: #include <regex.h> conditionally, so the file is
5771 CPP'able (for dependency scanning) even on systems that don't have
5774 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5776 Add new R4RS-compliant syntax for keywords.
5777 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5778 regardless of the setting of the `keywords' read option.
5779 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5780 can be re-read no matter what the setting of the `keywords' read
5783 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5785 Add support for POSIX regular expressions.
5787 * regex-posix.c, regex-posix.h: New files. (Some code
5788 is taken liberally from rx/rgx.c in the old Guile dist.)
5790 * init.c: Include regex-posix.h.
5791 (scm_boot_guile_1): Call scm_init_regex_posix.
5793 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5794 Add regex-posix.[ch] sources.
5795 * Makefile.in: Regenerated.
5797 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5798 to do this automatically? It didn't for me, bleh.)
5800 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5802 * fports.c (print_pipe_port): New function.
5803 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5804 latter doesn't even take the right arguments.
5806 * Makefile.am: Increment shared lib revision number. I think
5807 sometimes the uninstalled Guile finds the installed shared lib;
5808 Gord says doing this might help. As things turned out, I can't
5809 say whether it does.
5810 * Makefile.in: Regenerated.
5812 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5813 passing it as the closure argument to scm_boot_guile. (Bill
5816 * ports.c (print_void_port, putc_void_port, puts_void_port,
5817 write_void_port, flush_void_port, getc_void_port, close_void_port,
5818 noop0): Use ANSI prototypes instead of K&R declarations, so the
5819 initialization of void_port_ptob gets aggressively type-checked.
5820 Fix arguments of print_void_port and write_void_port. (Bill

5854 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5856 * script.c (scm_find_executable): Use prototype-style definition
5857 here; apparently it's not quite right to have const in a prototype
5858 and then use a K&R declaration. I wonder if stuff like this will
5859 go away if we compile with -Wrequire-prototypes, or whatever that
5860 is... (Bernard URBAN)
5862 * scmhob.h: New text from Bernard URBAN.
5864 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5866 * script.c: Don't #define const on hpux. Configure takes care of
5867 this. (Thanks to Larry Schwimmer.)
5869 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5870 decide whether to #include <unistd.h>, instead of listing a bunch
5871 of systems. Don't #include stdio twice. Removed dyked-out
5872 definition of scm_find_impl_file.
5874 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5876 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5877 library version info to 1:0.
5878 * Makefile.in: Regenerated.
5880 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5884 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5885 throw.c: Update copyright years; these files have been worked on
5886 significantly in 1997, but only had copyright years for 1996.
5887 Also, change name of copyright holder on some from Mikael
5888 Djurfeldt to Free Software Foundation; he has signed papers
5889 assigning the changes to the FSF.
5891 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5892 reason not to give the user the option.
5894 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5895 Return #f on end-of-file when scanning table (i.e. when called
5896 with no arguments). Try to catch errors, when we can.
5897 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5899 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5900 external declarations. These are useful.
5902 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5904 * posix.c: don't include <sys/select.h> or define macros for
5905 select, since they were not used in this file.
5907 * filesys.c (scm_select): make the fifth parameter microseconds,
5908 not milliseconds. let the fourth parameter be either a real value
5909 or an integer or #f. The first, second and third arguments can
5910 now be vectors: the type of the corresponding return set will be
5912 (set_element, get_element): new static procedures.
5914 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5916 * strports.c (scm_eval_string): New function.
5917 (scm_eval_0str): Trivially re-implemented in terms of
5919 * strports.h (scm_eval_string): New extern decl.
5921 * net_db.c (h_errno): Add extern decl for this.
5923 * fports.c (local_pclose): New function.
5924 (scm_pipob): Use it in the initializer here.
5927 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5928 Use a meaningful error message when signalling an error. For
5929 this, scm_gethost must check h_errno rather than errno.
5931 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5933 * Makefile.in: Regenerated, using automake-1.1p.
5935 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5937 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5938 not SCM_UNSPECIFIED.
5940 * script.c (scm_compile_shell_switches): don't append (quit) if
5942 (scm_shell): call scm_exit_status and exit on the result of the
5945 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5947 Ensure that shared substrings are handled properly when passed to
5948 a system call or other foreign function. Many thanks to Tim
5950 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5951 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5952 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5953 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5964 scm_strftime), vports.c (scm_make_soft_port): use
5965 SCM_COERCE_SUBSTR to make sure shared substrings are

5970 * error.c (scm_error): Add newline to error message.
5972 * init.c (scm_init_standard_ports): Doc fix.
5974 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5976 * dynl-shl.c: Completely replaced with new code from Bernard
5979 * script.c (scm_ice_9_already_loaded): New variable.
5980 (scm_compile_shell_switches): Use it.
5982 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5984 * filesys.c (scm_input_waiting_p): add missing third argument to
5987 * stime.c (scm_localtime): copy the result of localtime before
5988 calling gmtime in case they share a buffer.
5989 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5992 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5994 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5996 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5998 * Makefile.am (check-local): New target, which causes 'make check'
5999 to run gh_test_c and gh_test_repl, with some trivial input.
6000 * Makefile.in: Rgnrtd.
6002 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
6004 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
6007 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
6009 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
6010 sure how this was supposed to work.
6011 (scm_async_click): don't send SCM_TICK_SIGNAL.
6012 (scm_init_async): don't initialize %tick-thunk.
6014 * the following change doesn't affect the Scheme interface:
6015 gc-thunk is called at the end of garbage collection. however it's
6016 no longer implemented by pretending it's a signal.
6018 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
6019 system async corresponding to scm_gc_thunk.
6020 * async.h: declare scm_gc_async.
6021 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
6022 gc-thunk directly, instead of going through a signal handler.
6023 (scm_gc_async): new variable, points to the GC system-async.
6024 (scm_init_async): save the GC async as scm_gc_async instead
6025 of using system_signal_asyncs.
6026 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
6028 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
6030 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
6031 Don't screw up if we're interrupted.
6032 * Makefile.in: Regeneradet.
6034 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
6036 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
6038 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
6039 we're not using AM_INIT_GUILE_MODULE any more.
6040 * Makefile.in: Reneregated.
6042 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
6044 Functions for finding variable bindings, grace à Tim Pierce.
6045 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
6046 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
6048 Get 'make dist' to work again.
6049 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
6050 * Makefile.in: Regenerated, like a surry without a fringe on top.
6052 Changes for reduced Guile distribution: one configure script,
6054 * configure.in, configure: Removed.
6055 * acconfig.h, acinclude.m4: Moved to parent directory, where the
6056 real configure script lives.
6057 * Makefile.in, scmconfig.h.in: Regenerated.
6059 * init.c: #include "script.h", to get prototype for script.c's
6062 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
6064 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
6065 scm_must_malloc, not raw malloc.
6067 * script.c (scm_compile_shell_switches): Dyke out debugging output
6070 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6072 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
6074 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
6075 system has them. Hope this is safe. Previously
6076 sys/timeb.h was included if HAVE_FTIME was defined or if
6077 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
6078 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
6080 * ioext.c (scm_setfileno): add missing third argument to
6081 scm_misc_error call.
6083 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
6085 * eq.c (scm_equal_p): Correctly compare strings of different
6086 varieties. (Thanks to Tim Pierce.)
6088 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
6090 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
6091 #! block comment must occur on a line all by itself.
6093 Move most of the guts of shell command processing into libguile,
6094 so guile.c can be very small (and eventuallly auto-generated. (I
6095 mean, generated mechanically, not self-generated. Hmm.))
6096 * guile.c, script.c, script.h: New source files.
6097 * init.c (scm_boot_guile_1): Call scm_init_script.
6098 * libguile.h: #include "script.h".
6099 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
6100 targets, for new executable.
6101 (libguile_la_SOURCES): Mention script.c.
6102 (modinclude_HEADERS): Add script.h.
6103 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
6104 not dynamic linking is enabled. This is because we're generating
6105 executables now. Move CY_AC_WITH_THREADS call after those, so the
6106 values of cy_cv_threads_libs captures the libs chosen above.
6107 * Makefile.in, configure, aclocal.m4: Regenerated.
6109 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
6110 We don't maintain this interface any more, and it just confuses
6113 * alloca.c: #include <scmconfig.h>, not <config.h>.
6114 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
6115 it'll get included in disties.
6117 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
6119 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
6120 be distributed, because they confuse people.
6121 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
6123 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
6125 * configure.in: check for presence of gethostent (not present on
6126 OpenBSD by default).
6127 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
6128 * configure, scmconfig.h.in: Regenerated.
6130 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
6132 * backtrace.c (scm_backtrace): Split message string across
6133 newlines properly. GCC is more tolerant of this than other
6136 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
6138 Merge threads directory into libguile.
6139 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
6140 threads.h: New source files.
6141 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
6142 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
6144 (modinclude_HEADERS): Add threads.h, coop-defs.h.
6145 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6146 coop-threads.c.cygnus, coop-threads.h.cygnus.
6147 * configure.in: If we're using threads, include threads.o in
6149 * _scm.h, libguile.h: threads.h lives in this directory now.
6150 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6151 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
6152 currently used, but brought along for information's sake.
6153 * ChangeLog-threads: log from old 'threads' directory.
6154 * Makefile.in, configure: Rebuilt.
6156 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
6158 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
6161 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
6163 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
6165 Merge GH interface library into libguile.
6166 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
6167 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
6168 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
6169 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
6171 (EXTRA_libguile_la_SOURCES): ... here.
6172 (pkginclude_HEADERS): Add variable, to get gh.h installed.
6173 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
6174 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
6175 New variables, describing how to build the gh test programs.
6176 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
6177 build the test programs, and we probably should have been linking
6178 libguile.la against them all along, to support AIX shared libs.
6179 Add cflags for threads to CFLAGS; add libs for threads to new
6180 variable THREAD_LIBS, used in Makefile.am.
6181 * ChangeLog-gh: log from old `gh' subdirectory.
6182 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
6184 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
6186 * acconfig.h: Undo change of Apr 9; including the definition of
6187 PACKAGE in the guile headers conflicts with applications' own
6189 * scmconfig.h.in: Regenerated.
6191 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

6197 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
6198 when PROC is receiving no arguments.
6200 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
6202 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
6203 have S_IFSOCK. This is the case under Ultrix.
6205 * posix.c (scm_status_exit_val, scm_status_exit_val,
6206 scm_status_term_sig, scm_status_stop_sig): Modified to work with
6207 Ultrix versions of WIFSTOPPED, etc., which assume that their
6208 arguments are lvalues (hmm).
6210 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
6212 * eval.c: Doc fixes.
6214 * throw.c: Doc fixes; rearranged.
6216 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
6218 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
6220 * acconfig.h: Added entry for PACKAGE.
6221 * scmconfig.h.in: Regenerated.
6223 Changes to work with automake-1.1n, which has better libtool support.
6224 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
6225 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
6227 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
6229 * Makefile.in: Rebuild.
6231 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6233 * stime.c (scm_mktime): take an optional zone argument.
6234 (scm_localtime): check putenv return value.
6235 (scm_strftime, scm_strptime): moved from posix.c. move #include
6237 stime.h, posix.h: update prototypes.
6238 (bdtime2c, setzone, restorezone): new static procedures.
6239 (scm_mktime, scm_strftime): use them.
6240 (scm_strftime): don't call mktime before strftime. Use
6241 filltime for return value.
6242 (filltime): convert NULL zname to #f.
6243 (scm_strptime): return a count of characters consumed, not
6244 the remaining string.
6246 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6248 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
6249 (scm_mktime): likewise.
6251 Uncomment localtime and mktime.
6253 * configure.in: add AC_STRUCT_TIMEZONE.
6255 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6257 * stime.c (scm_init_stime): don't define ticks/sec.
6258 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
6259 return value problem and is still portable.)
6261 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6263 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
6264 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
6265 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6266 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
6267 cpp_err_symbols.c): Corresponding changes.
6268 * Makefile.in: Regenerated.
6270 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6272 * posix.c (scm_putenv): don't check HAVE_PUTENV.
6273 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
6274 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6275 * putenv.c: new file, from sh-utils 1.12.
6277 * posix.c (scm_environ): use malloc in place of scm_must_malloc
6278 since allocation isn't for Scheme objects.
6279 (scm_putenv): copy strings before placing in the environment.
6281 * stime.c (scm_current_time): throw an error if time returns -1,
6282 instead of returning #f.
6283 (scm_get_internal_real_time, scm_get_internal_real_time): use
6284 scm_long2num for return value instead of SCM_MAKINUM.
6286 * stime.h: prototypes updated.
6288 * stime.c (scm_time_in_msec): apparently unused, deleted.
6290 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
6292 * configure.in: check for gettimeofday.
6294 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
6295 which may be more usefully portable than a gettimeofday interface.
6297 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
6299 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
6301 * Makefile.in: Regenerated.
6303 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6305 * stime.c (filltime): recovered static procedure.
6306 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
6309 * posix.h: add prototype for scm_close_pipe, remove prototypes for
6310 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
6312 * posix.c (scm_mknod): split the mode argument into type and perms
6313 arguments, like the extra fields returned by stat.
6315 * fports.c (scm_pipob): set the close, free and print procedures.
6316 (scm_close_pipe): new procedure.
6318 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
6319 define them in boot-9.scm
6321 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6323 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
6324 wan't defined. Don't include fd.h.
6326 * Previously fd.h was regenerated whenever configure was run,
6327 forcing a couple of files to be recompiled.
6329 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
6330 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
6331 Check for _fileno as well as _file.
6333 * ioext.c: don't fd.h.
6334 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
6337 * Change the stratigy for getting information about errno
6338 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
6339 generating lists of symbols during the build process, which will
6340 not always work, include comprehensive lists in the distribution.
6341 To help keep the lists up to date, the "check_signals" and
6342 "check_errnos" make targets can be used.
6344 * configure.in: don't check for a command to extract errno codes.
6345 * Makefile.am: update file lists, remove errnos.list and errnos.c
6346 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
6347 check_errnos targets.
6348 (CLEANFILES): remove errnos.c and errnos.list, add
6349 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6350 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6351 * errnos.default: deleted.
6352 * cpp_signal.c: new file.
6353 * cpp_errno.c: renamed from errnos_get.c.
6354 * cpp_err_symbols, cpp_sig_symbols: new files.
6355 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6356 * error.c (scm_init_error): #include cpp_err_symbols instead of
6358 * posix.c (scm_init_posix): don't intern signal symbols. #include
6361 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6363 * strop.c (scm_i_index): allow the lower bound to be equal to the
6364 length of the string, so a null string doesn't always give an error.
6366 * posix.h: new prototypes.
6367 * posix.c (scm_status_exit_val, scm_status_term_sig,
6368 scm_status_stop_sig): new functions, as in scsh. They break down
6369 process status values as returned by waitpid.
6371 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6373 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6374 configure doesn't know about it.
6376 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6378 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6380 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6381 which defines C variables with global linkage.
6383 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6385 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6388 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6390 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6391 has time to check why this doesn't work well with continuations.
6393 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6395 * Fix shell syntax error; some shells won't tolerate
6396 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6398 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6400 * posix.c (scm_uname): throw an error if uname fails instead
6403 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6405 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6408 * async.c (scm_ints_disabled): definition moved from error.c.
6410 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6412 * acconfig.h: Removed PACKAGE.
6414 * scmconfig.h.in: Regenerated.
6416 * snarf.h: g++ says it's non-portable not to specify the first
6417 argument in a varargs declaration. I introduced the first
6418 argument by using preprocessor conditionals.
6420 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6422 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6423 (scm_freopen): use RO string macros for filename and modes.
6424 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6426 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6427 (scm_mknod): use RO string macros for path.
6429 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6430 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6432 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6433 use SCM_ROSTRINGP and SCM_ROCHARS.
6435 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6437 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6440 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6441 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6442 support for byte vectors.
6444 * print.c (scm_iprin1): Limit number of vector elements printed
6445 according to pstate->length.
6447 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6449 * backtrace.c (scm_display_error_message): don't segv if message
6452 * error.h: prototype for scm_error_scm.
6454 * error.c (scm_error_scm): new procedure, reimplements scm-error
6455 in C and uses scm_error.
6457 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6459 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6460 pointer to the Scheme variable read-hash-procedures and intern it
6461 in scm_init_read. Modify scm_read_hash_extend and
6462 scm_get_hash_procedure to use the pointer.
6464 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6466 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6467 (SCM_KEYWORD_STYLE): defined.
6469 * read.c (scm_read_opts): add a keywords option. This isn't a
6470 boolean option, in case someone wants to add support for DSSSL
6472 Setup scm_keyword_prefix symbol.
6473 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6475 I've left keyword support disabled by default, since it doesn't
6476 seem to break the module system and it gives R4RS standard behaviour.
6477 It can be reactivated with (read-set! keywords 'prefix).
6479 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6481 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6482 before constructing arbiter.
6484 * eval.c (scm_m_define): Bugfix: Check that the object is a
6485 closure before setting the procedure property!
6487 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6489 * ports.c: Removed `ungetc-char-ready?'.
6491 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6493 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6494 (idea from Mikael: make it a pair so scm_permanent object only
6496 (scm_read_hash_extend): don't call scm_permanent_object.
6497 (ideas from Mikael): if chr is already in the list, replace its
6498 procedure instead of appending it again. If proc is #f, remove
6500 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6502 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6504 * gdbint.c (gdb_read): update scm_lreadr usage.
6506 * load.h: update prototypes.
6508 * load.c (scm_primitive_load, scm_read_and_eval_x,
6509 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6511 * read.h: add prototype for scm_read_hash_extend. Change args for
6514 * read.c (scm_read_hash_procedures): new variable.
6515 (scm_read_hash_extend): new procedure.
6516 (scm_get_hash_procedure): new procedure.
6517 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6518 for extended # processing.
6519 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6520 scm_read_token): remove case_i, sharp arguments. Change callers.
6522 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6524 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6525 (SCM_CASE_INSENSITIVE_P): define.
6527 * read.c: add case-insensitive option to scm_read_opts.
6528 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6529 to determine whether to convert symbol case.
6530 (default_case_i): definition removed.
6531 * read.c (scm_read_token): if case_i, downcase ic before doing
6534 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6536 * configure.in: Added configuration option `guile-debug'.
6537 Configure with --enable-guile-debug if you want a bunch of extra
6538 functions used for debugging when developing Guile.
6540 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6542 * procs.c (make-cclo): New undocumented debugging procedure: Make
6543 compiled closure with internal procedure PROC and length LENGTH.
6544 Only compiled if GUILE_DEBUG is defined.
6546 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6548 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6550 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6552 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6553 with 3 or more args internally to the evaluator.
6555 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6557 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6558 with 3 or more args internally to the evaluator. This is mainly
6559 because we don't want to pass entry and exit points of the
6560 debug support twice, but it also seems to increase the speed of
6561 the evaluator for such calls (e. g. (+ 1 2 3)).
6563 * backtrace.c (scm_display_application): New procedure:
6564 display-application; Set fancy printing parameters individually
6565 for different types of display (backtrace, error, application).
6566 (These should of course be customizable!)
6568 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6569 clear the CHECK-flags.
6571 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6573 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6575 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6577 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6578 from pairs with a GLOC in the car.
6580 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6581 otherwise `symbol-hash' will behave badly.
6582 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6583 we get segmentation fault!
6585 * symbols.c: Added #include "weaks.h". New functions:
6586 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6587 moved to an extraneous library when we split libguile.)
6589 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6591 * filesys.c (scm_stat): stat now takes fport arguments too as
6592 documented in the manual.
6594 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6596 * debug.c (scm_single_step): Bugfix: Call continuation with
6597 scm_call_continuation instead of throwing to it.
6599 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6601 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6602 argument wasn't declared to be optional.
6604 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6606 * stime.c (scm_init_stime): Add feature "current-time".
6608 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6610 * throw.h: prototype for scm_exit_status.
6611 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6612 args to derive an exit status. Allows (quit) to work from a
6614 (scm_exit_status): new function.
6617 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6619 * eval.c (scm_deval): Removed some old code.
6620 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6622 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6625 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6628 * procs.c: Introduce the existent C function scm_thunk_p at the
6629 Scheme level as well.
6631 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6633 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6634 used from C to easily lookup the value of a symbol in the current
6637 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6639 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6640 scm_init_unif in this file. This will also fix a previous problem
6643 * configure.in: Added AM_MAINTAINER_MODE
6645 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6647 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6650 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6652 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6653 source files that are not always included in libguile but should
6654 have their dependencies calculated by automake. This variable is
6655 recognized by automake, no further magic is needed.
6656 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6657 to deal exclusively with *.lo files, as it seems. The *.o files
6658 are built automatically when the corresponding *.lo file gets
6661 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6663 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6666 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6668 * unif.c (scm_array_set_x): minor change to argument error checking.
6670 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6672 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6673 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6674 They should only be included in the library at configure.in's
6676 (libguile_la_LDADD): Include the appropriate .lo files here.
6677 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6678 so we know when to build them (and their .lo bretheren).
6679 * configure.in (LIBLOBJS): New substituted variable. We let
6680 configure decide which .o files to include in LIBOBJS, and then
6681 put the corresponding list of .lo files in LIBLOBJS. The latter
6682 is what we pass to libtool.
6683 * Makefile.in, configure: regenerated.
6685 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6687 * symbols.c (scm_sysintern0): New function. Contains the core of
6688 old scm_sysintern but doesn't take a second value argument.
6689 (scm_sysintern): Now uses scm_sysintern0.
6690 (scm_sysintern_no_module_lookup): Renamed to
6691 scm_sysintern0_no_module_lookup and doesn't take a second value
6692 argument any longer.
6694 * symbols.h (scm_sysintern0: Added declaration.
6696 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6697 scm_sysintern when interning option keys. Otherwise we risk
6698 destroying the values of already interned variables.
6700 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6701 scheme-level boolean (use SCM_NFALSEP).
6703 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6705 (scm_backtrace): New function. (C version of old function from
6706 boot-9.scm) Motivation: Make it possible to display backtraces
6707 without depending on boot-9.scm. (I'm uncertain if this
6708 motivation is good enough...)
6710 * root.h (scm_root_state): Add member the_last_stack_var.
6711 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6713 * root.c (mark_root): Mark scm_the_last_stack_var.
6715 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6718 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6720 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6721 1. mark_lazy_catch didn't mark the smob.
6722 2. Both functions above have standard variants:
6723 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6724 free_lazy_catch --> scm_free0.
6726 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6728 * throw.c (scm_internal_lazy_catch): New function.
6729 (scm_lazy_catch): Rewritten to use it.
6730 (scm_ithrow): Handle the new lazy catch representation.
6731 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6732 that doesn't have a jmpbuf is a lazy catch clause.
6733 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6734 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6735 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6737 (scm_init_throw): Register the new lazy-catch smob type.
6738 * throw.h (scm_internal_lazy_catch): decl for new function.
6740 * throw.c (scm_internal_catch): Doc fixes.
6742 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6743 configure.in. Including this might cause problems if applications
6744 that link against libguile include their own copies of alloca, but
6745 if they're using autoconf, they should be adding libguile to LIBS
6746 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6747 the copy in libguile, and things will be okay. (I think.)
6749 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6751 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6753 strop.h: move prototypes too.
6755 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6757 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6760 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6761 etc. I deleted them from filesys.c long ago, but didn't
6762 notice they were here too (although ineffective since
6763 sys/stat.h wasn't included).
6765 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6767 * eval.c: Don't define alloca in GCC case. gcc will automatically
6768 use __builtin_alloca if appropriate.
6770 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6772 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6773 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6774 that values of automatic variables are preserved. See comments
6775 for safe_setjmp for details.
6777 Change from Thomas Morgan:
6778 * variable.c: Include eq.h.
6779 (var_equal): New function.
6780 (variable_smob): Use var_equal as the discriminator for variables.
6782 * throw.c (s_throw): Remove extraneous declaration.
6784 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6785 * eval.c: Add necessary CPP cruft to support that.
6786 * configure, Makefile.in, scmconfig.h.in: regenerated.
6788 Change from Thomas Morgan:
6789 * procprop.c (scm_procedure_properties): Convert the Scheme
6790 boolean returned by scm_procedure_p into a C boolean before using
6791 it as a condition for SCM_ASSERT.
6792 (scm_procedure_property): Likewise.
6794 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6795 indications of Unixness.
6798 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6800 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6802 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6804 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6805 "unknown # object" error messages.
6807 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6808 (scm_i_index) and declare it static. Add a 'direction' argument
6809 to indicate what way the search should go.
6810 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6812 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6813 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6815 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6817 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6819 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6820 to avoid clash with various scsh forks.
6822 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6824 The following two changes (ramap.c, throw.c) are motivated by the
6825 apparent unportability of forward declarations of static arrays of
6826 the form `static foo bar[];'.
6828 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6829 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6831 * throw.c (scm_throw): Moved above scm_ithrow.
6833 * options.h: Removed the extern declarations of scm_yes_sym and
6834 scm_no_sym since these are static.
6836 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6838 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6840 * Makefile.am: remove AWK=@AWK@.
6841 Add a rule for generating errnos.list.
6842 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6844 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6845 don't extract errnos, just set a variable (avoids the
6846 need to recompile error.c just because configure is run.)
6848 * unif.h: update prototypes.
6849 * unif.c (scm_uniform_array_read,write): change the offset and
6850 length arguments to start and end, for consistency.
6852 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6854 * ioext.h: update prototypes.
6855 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6856 scm_read_line_x, it's a more general procedure using an
6857 interface from scsh. read-line and read-line! are now defined
6859 Note that the new read-line trims the terminator
6860 by default, previously it was appended to the returned string. An
6861 optional argument specifies how to process the terminator (scsh
6862 compatible). For the old behaviour: (read-line port 'concat).
6863 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6864 returns a pair, but is converted to multiple values if the scsh
6867 socket.h: update prototypes.
6868 * socket.c (scm_recvfrom): for consistency with other procedures,
6869 take start and end as separate optional arguments.
6870 (scm_recv, scm_recvfrom): don't allow the second argument
6871 to be a size, only a buffer. Change the scheme names to
6872 recv! and recvfrom!. Don't return the buffer.
6874 * ioext.h, posix.h: move prototypes too.
6875 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6876 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6877 "read.h" and "unif.h".
6878 * ioext.c: include "chars.h"
6880 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6882 * dynl.c: The dynamic linking and module registration functions
6883 are now defined even when dynamic linking is not available for the
6884 host system. Some of their functionality can be done without
6885 dynamic linking; when it's really needed, they throw errors.
6887 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6889 * configure.in: Only define DYNAMIC_LINKING when one of the system
6890 dependent functions is detected.
6891 * dynl.c (scm_dynamic_func): New function to get the address of a
6892 function in a dynamic object.
6893 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6894 produced by scm_dynamic_func as the thing to call.
6896 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6898 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6899 (scm_register_module_xxx, scm_registered_modules,
6900 scm_clear_registered_modules): New functions.
6902 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6904 * symbols.c (scm_sysintern): Renamed to
6905 scm_sysintern_no_module_lookup.
6906 (scm_sysintern): New function to take the place of the old
6907 scm_sysintern. It uses the current toplevel lookup closure to give
6908 the symbol its value. This is a temporary hack to put packages
6909 like gtcltk into their own module.
6910 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6911 us whether `scm_top_level_lookup_closure_var' has been initialized
6913 * eval.c (scm_init_eval): Set it.
6915 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6917 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6918 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6920 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6922 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6923 scm_sys_dup): deleted: FD capability will be added to other
6925 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6926 scm_fd_free, fd_smob, scm_intern_fd.
6927 (scm_open): renamed from scm_sys_open. Return a port instead of
6928 an FD object. Make the mode argument optional.
6929 (scm_sys_create): deleted, it's just a special case of open.
6930 (scm_init_filesys): move interning of constants O_CREAT etc.,
6931 here (were previously using SCM_CONST_LONG macro).
6932 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6934 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6935 include "fports.h" and <stdio.h>
6936 (scm_stat, scm_select): don't support FD objects.
6938 * error.h: adjust scm_syserror_msg prototype.
6939 * error.c (scm_syserror_msg): take an extra argument for errno.
6940 Using the global value didn't always work, since it could be
6941 reset by procedure calls in the message or args arguments.
6943 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6944 I don't understand why the check was there (and what about the
6947 * strop.c (scm_string_copy): allow shared substrings to be copied.
6949 * unif.h: corresponding change to prototypes.
6950 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6951 recognize two new optional arguments: offset and length. Allow
6952 the port argument to be an integer (file descriptor, for scsh).
6953 Include <unistd.h> for "read" prototype.
6955 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6957 * socket.c: don't include filesys.h.
6959 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6961 * Makefile.am: add AWK=@AWK@ (?)
6963 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6965 Add a rule to generate errnos.c from errnos.
6966 * error.c (scm_init_error): include errnos.c.
6967 * errnos_cnvt.awk: new file, converts the list of errno codes to
6969 * errnos_get.c: new file.
6970 * errnos.default: new file, contains errnos to try if they can't
6971 be extracted from errno.h.
6972 * configure.in: if using GCC, try and extract errno codes from
6976 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6978 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6979 * Makefile.am: Made libguile into a libtool library.
6980 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6981 Set libtool_libs to indicate that libguile is a libtool library.
6982 See guile/ChangeLog for details.
6983 * .cvsignore: ignore "*.lo", the libtool library objects.
6985 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6987 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6988 use htons in getservbyport argument.
6990 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6992 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6993 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6996 * objprop.c (scm_object_property): No need to take the CDR of the
6997 value returned by scm_object_properties, since Aug 20 change.
6999 * configure.in: When checking for struct linger, #include
7000 <sys/types.h> as well as <sys/socket.h>. I've never known
7001 <sys/types.h> to cause any portability problems, and Solaris's
7002 <sys/socket.h> needs it.
7003 * configure: Rebuilt.
7005 I think the Sun compiler has chosen a perverse way to interpret
7006 ANSI declarations combined with K&R definitions. We'll
7007 appease it a little bit. But when it invades France, we fight.
7008 * print.c (scm_iprlist): Change 'tlr' argument to an int.
7009 * print.h (scm_iprlist): Here too.
7010 * numbers.c (scm_divbigdig): Change definition to match
7011 declaration in numbers.h.
7012 * unif.c (scm_makflo): Change definition to match declaration in
7015 * init.c (scm_boot_guile): Don't return the value of
7016 scm_boot_guile_1. This function doesn't return a value;
7017 scm_boot_guile_1 doesn't return a value (or return at all).
7019 * eval.c (unmemocopy): Add a semicolon to appease the Sun
7022 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
7023 compile. I have a feeling this function is a bad idea anyway ---
7024 one should always test for features, not systems.
7026 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
7027 semicolons. Only pure luck kept this from being noticed earlier.
7029 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
7031 * socket.c (scm_recvfrom): Added missing semicolon.
7033 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
7035 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
7036 the buffer and start and end positions for scsh networking
7039 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
7041 * configure.in: Revert previous change to this file; the problem
7042 is due to transient automake weirdness.
7043 * configure: Rebuilt.
7045 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
7046 PLUGIN/guile.libs. configure generates the latter from the former.
7047 * Makefile.in: Rebuilt.
7049 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
7050 need this if we install scripts, like guile-snarf.
7051 * configure: Rebuilt.
7053 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
7055 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
7057 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
7059 * socket.c (scm_addr_vector): fix faulty scm_listify.
7061 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
7063 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
7064 style block comment is no longer considered an error.
7066 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
7068 * PLUGIN/guile.libs.in: New file.
7069 * PLUGIN/guile.libs: Removed from repository.
7070 * configure.in: Create PLUGIN/guile.libs from
7071 PLUGIN/guile.libs.in. This is for including additonal libraries
7072 needed for dynamic linking.
7073 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
7074 instead of PLUGIN/guile.libs.
7076 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
7078 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
7080 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
7081 occurrences of the given element from the list, not just the
7082 first. This is how the Emacs Lisp functions behave, how the
7083 analogous Common Lisp functions behave, and (I believe) how the
7084 older Maclisp functions worked. I realize that this change may
7085 break code, but it seemed better to break it before the Guile
7088 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
7089 Their prototypes were already present in gc.h, but they weren't
7091 (scm_init_storage): Initialize scm_protects.
7092 * root.c (scm_protects): New element of scm_sys_protects.
7094 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
7096 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7098 * libguile.h: Added #include "libguile/net_db.h".
7100 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
7101 30 change. That file is only meant for communication between the
7102 configuration process and load.c. If code linked against libguile
7103 wants to get at the paths mentioned in libpath.h, it can call
7104 functions declared in load.h.
7106 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7108 * libguile.h: Removed #include "libguile/fdsocket.h"
7110 * net_db.c: Added #include <sys/socket.h>.
7112 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
7114 * filesys.c (scm_input_waiting_p): use select in preference to
7115 FIONREAD, since the latter doesn't detect EOF.
7116 Throw error if neither select nor FIONREAD available.
7118 * socket.c (scm_connect): take a port, not a fd object.
7119 (scm_fill_sockaddr): throw an error if fam is not recognised.
7120 (scm_bind): use scm_fill_sockaddr.
7121 (scm_listen): take a port, not a fd object.
7122 (scm_accept): take and return a port. return #f in the car if
7123 address can't be got
7124 (scm_sock_fd_to_port): new procedure.
7125 (scm_socket): use scm_sock_fd_to_port.
7126 (scm_addr_vector): throw error if unrecognised address type.
7127 take an extra argument with the calling procedure name.
7128 (scm_getsockname): take a port. return #f if address can't be got.
7129 (scm_getpeername): take a port. return #f if address can't be got.
7130 (scm_recvfrom): take a port. return #f for address component if can't
7132 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
7133 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
7135 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
7137 * throw.c (scm_internal_catch): Make body funcs and handler funcs
7138 use separate data pointers, to allow them to be designed
7139 independently and reused.
7140 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
7141 Renamed from catch_body, catch_handler, and uncaught_throw; made
7143 (struct scm_catch_body_data): Renamed from catch_body_data; moved
7145 (scm_catch): Use the above.
7146 (scm_throw): Don't bother printing a message for an uncaught
7147 throw; we establish a default handler in init.
7148 * throw.h (scm_internal_catch): Prototype updated.
7149 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
7151 (struct scm_body_thunk_data): New structure, used as data
7152 argument to scm_body_thunk.
7153 * init.c (struct main_func_closure): New structure, packaging up
7154 the data to pass to the user's main function.
7155 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
7156 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
7157 scm_internal_catch to establish a catch-all handler, using
7158 scm_handle_by_message. This replaces the special-case code in
7160 (invoke_main_func): Body function for scm_internal_catch; invoke
7161 the user's main function, using the main_func_closure pointer to
7162 decide what to pass it.
7163 * root.c (struct cwdr_body_data): Remove handler_proc member.
7164 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
7165 (cwdr_handler): Removed.
7167 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7169 * socket.h (SCM_P): update bind prototype.
7170 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
7171 include "feature.h".
7172 (scm_socket): return a port, not a file descriptor object.
7173 include "fports.h" and <unistd.h>
7174 (scm_bind): take a port, not a file descriptor object.
7175 take an extra argument for address args.
7177 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
7178 INADDR_NONE, INADDR_LOOPBACK.
7180 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7182 * init.c: include net_db.h and not fdsocket.h.
7183 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
7185 * Makefile.am: corresponding changes.
7186 * socket.h: renamed from fdsocket.h, fix names.
7187 * net_db.h: renamed from socket.h, fix names.
7188 * socket.c: renamed from fdsocket.c.
7189 remove _sys from procedure names.
7190 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
7191 add "socket" to features list.
7192 * net_db.c: renamed from socket.c.
7193 remove _sys from procedure names.
7194 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
7195 add "net-db" to features list.
7196 include "net_db.h". don't include <sys/socket.h> or
7199 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7201 * tags.h (scm_tags): Removed comma at end of last enumerator.
7203 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
7205 Don't use GCC extensions to allocate space for debugging frames.
7206 (Here he goes again! Why do we put up with this?!)
7207 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
7208 an scm_debug_info structure, not an in-line array of them. Add
7209 'info' member, to say how many vect elements we've used, for eval
7211 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
7212 a new variable debug_info_end to mark the end of vect, instead of
7213 the address of the 'info' pointer itself.
7214 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
7215 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
7216 (SCM_APPLY): Explicitly allocate space for debug.vect.
7217 * debug.c (scm_m_start_stack): Same, for vframe.vect.
7218 * stacks.c: Adjusted for new debug frame structure.
7219 (RELOC_INFO, RELOC_FRAME): New macros.
7220 (stack_depth, read_frames): Use them, and new scm_debug_frame
7221 element 'info', instead of magically knowing that eval frames have
7222 an info pointer sitting after vect.
7223 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
7225 (scm_init_stacks): Formatting tweaks.
7227 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
7229 Give GCC more control flow information, so it can be sure that
7230 variables aren't used uninitialized.
7231 * error.h (scm_error, scm_syserror, scm_syserror_msg,
7232 scm_sysmissing, scm_num_overflow, scm_out_of_range,
7233 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
7234 scm_misc_error): Tell GCC that these functions never return.
7235 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
7236 out the field type, call abort if SCM_ASSERT returns, to placate
7238 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
7239 scm_wta ever returns. We can't handle this case anyway, and this
7240 gives the optimizer more information.
7241 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
7242 scm_wta ever returns.
7244 In some cases, the code is fine, but GCC isn't smart enough to
7245 figure that out; this usually happens when one variable is only
7246 initialized and used when a particular condition holds true, and
7247 we know that condition will never change within a given invocation
7248 of the function. In this case, we simply initialize the variables
7249 to placate the compiler, hopefully to a value which will cause a
7250 crash if it is ever actually used.
7251 * print.c (scm_iprin1): Initialize mw_pos.
7252 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
7253 * throw.c (scm_ithrow): Initialize dynpair.
7254 * unif.c (scm_uniform_vector_ref): Initialize cra.
7255 * struct.c (init_struct): Initialize prot.
7256 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
7258 * strports.c (scm_eval_0str): Don't return uninitialized garbage
7259 if EXPR contains no expressions.
7261 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7263 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
7264 cause an infinite loop (???). So much for the algebraic
7265 equivalency of variable-sized arrays and alloca...
7267 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
7269 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
7270 a SCM boolean, not a C boolean.
7272 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
7274 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
7275 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
7276 rules for raising scm_mtrigger. Previously, unfortunate but not
7277 unlikely circumstances could result in almost constant invokation
7278 of the gc. Now, this situations should be less likely, but they
7279 are not prevented completely.
7281 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
7283 * numbers.c (scm_fuck): Procedure removed; looks like old test
7285 * numbers.h: Prototype removed.
7287 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
7289 * debug.h (scm_debug_frame): Change `vect' member from an in-line
7290 array to a pointer, to match my Nov 21 change in eval.c.
7292 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7294 * libguile.h: Added #include "libguile/backtrace.h", #include
7295 "libguile/stacks.h".
7297 * strings.c (scm_string scm_make_string scm_string_ref
7298 scm_string_set_x scm_string_equal_p scm_string_append):
7299 Bugfix according to scm patch from Aubrey Jaffer:
7300 Corrected long-standing
7301 (not (eqv? (integer->char 128)
7302 (string-ref (make-string 1 (integer->char 128)) 0)))
7303 bug found by John Kozak <jk@noontide.demon.co.uk>.
7305 * strports.c, strports.h: Make scm_eval_0str return the value of
7306 the last expression evaluated (previously, it returned void).
7308 * strports.c, strports.h: New function: scm_read_0str. Does what
7311 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7313 * simpos.c (scm_getenv): return #f if string can't be found in the
7314 environment instead of throwing an exception, for compatibility
7315 with numerous other systems.
7317 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
7319 * Makefile.am (.c.x): Use guile-snarf.
7320 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
7322 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
7324 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7326 * backtrace.c (scm_display_error_message): Made non-static, and
7327 renamed from display_error_message.
7328 * backtrace.h (scm_display_error_message): Added extern decl.
7329 * throw.c (uncaught_throw): Use it to display the error message.
7331 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
7333 * inet_aton.c: Use #if 0, not #ifdef 0.
7335 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
7337 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
7338 to convert the returned value.
7339 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
7340 the offset argument.
7342 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7344 Add new interface to catch/throw, usable from C as well as
7346 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
7347 (scm_internal_catch): New function, replaces...
7348 (scm_catch_apply): Deleted.
7349 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7350 mechanism which is a bit more code, but can be used nicely from C
7351 and implement the Scheme semantics as well.
7352 (scm_internal_catch): This is the replacement; it's named after
7353 the analogous function in Emacs.
7354 (scm_catch): Reimplemented in terms of the above.
7355 (struct catch_body_data, catch_body, catch_handler): New
7356 functions, used by scm_catch.
7357 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7358 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7359 support for new cwdr.
7361 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7364 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7366 * acconfig.h: Added DYNAMIC_LINKING symbol.
7367 * configure.in: Add option and checks for dynamic linking.
7368 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7369 dynl.h: New files for dynamic linking support.
7370 * Makefile.am (libguile_a_SOURCES):
7372 (modinclude_HEADERS): Added "dynl.h".
7373 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7375 * init.c (scm_boot_guile_1): Call
7376 scm_init_dynamic_linking to initialize dynamic linking support.
7378 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7380 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7381 (as we Schemers say). It needs to be global, so that I can tweak
7382 it for the proper operation of unexec.
7383 (scm_boot_guile_1_live): New variable, see above.
7385 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7387 * guile-snarf.sh: Removed.
7388 * PLUGIN/guile.libs: Added dependency for -lm.
7389 * acinclude.m4: Renamed from aclocal.m4.
7390 * PLUGIN/greet: Removed.
7391 * Makefile.am, aclocal.m4: New files.
7392 * configure.in: Updated for Automake.
7394 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7396 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7397 and not top_level_lookup_thunk_var.
7399 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7401 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7403 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7405 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7406 Scheme function, instead of syntax. Single argument is now a
7409 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7411 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7412 scm_ra_divide): Properly terminate statements passed as arguments
7413 to IVDEP macros. (Thanks to Bernard Urban.)
7415 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7416 with non-constant sizes. (Thanks to Bernard Urban.)
7418 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7420 It's an "eval closure", not an "eval thunk." A thunk is a
7421 function of no arguments.
7422 * root.h (struct scm_root_state): Renamed
7423 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7424 (scm_top_level_lookup_closure_var): Renamed from
7425 scm_top_level_lookup_thunk_var.
7426 * root.c (mark_root): Uses changed.
7427 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7428 * init.c (scm_start_stack): Uses changed.
7429 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7430 Change scheme-visible name to *top-level-lookup-closure* from
7431 *top-level-lookup-thunk*.
7433 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7435 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7436 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7438 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7440 * gc.c (struct scm_heap_seg_data): Doc fixes.
7442 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7443 sweeping. Then, prepend each segment's free cells to its
7444 freelist, rather than wiping out the old value. (Thanks to Marius
7447 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7448 scm_check_freelist, scm_debug_newcell): New functions and
7449 variables, for debugging freelist problems.
7450 * pairs.h (SCM_NEWCELL): New debugging version added.
7451 * gc.h (scm_debug_newcell): Added extern declaration, used by
7452 debugging version of SCM_NEWCELL.
7454 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7456 On some systems <libc.h> conflicts with <unistd.h>, and should not
7457 be #included at all.
7458 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7459 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7460 * configure.in: Call it.
7461 * posix.c, filesys.c: Use its results to decide whether or not to
7463 * configure, scmconfig.h.in: Rebuilt with autoconf and
7466 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7468 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7469 pointer to the stdio stream before calling scm_setbuf0, so the
7470 latter will be able to retrieve it. I'm surprised this didn't
7471 segfault earlier. (Thanks to Christopher Lee.)
7473 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7475 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7478 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7480 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7481 number of stack narrowing specifier pairs. The first specifier in
7482 a pair controls inner border, the second the outer border. A
7483 number means cut that number of frames, a procedure object means
7484 cut until that object is found in operator position in a frame.
7486 * root.c (cwdr): Bugfix.
7488 * read.c: Recording of positions disabled by default.
7490 * procs.c (scm_closure_p): New function.
7492 * posix.c (scm_tmpnam): New function.
7494 * load.c: Added #include "throw.h".
7495 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7498 * load.c, load.h (scm_read_and_eval_x): New function.
7500 * eval.c: Renamed debug option "deval" to "debug".
7502 (scm_eval_x): `eval!' is no longer accessible from the scheme
7503 level. Motivation: We can't allow operations which introduce
7504 glocs into the scheme level. Guile's type system can't handle
7505 these as data. Use `eval' or `read-and-eval!' as replacement.
7507 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7508 SCM_CONSP since this is a macro!; Set vframe.prev to
7509 scm_last_debug_frame instead of 0. In this way we can look
7510 "above" the virtual start stack frame if we wish.
7511 (scm_debug_hang): New function: Useful for debugging Guile in
7512 certain tricky situations. Will probably be removed later...
7514 * debug.h: Changed semantics of debug option "backtrace". This
7515 option now only indicates whether we want automatic backtrace at
7518 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7520 * ports.c: #include "filesys.h"
7521 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7523 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7524 Motivation: This is system specific code which is related to file
7525 I/O. It also may use select. Added code by Gary Houston to
7526 detect presence of character in stdio buffers.
7528 * libguile.h: #include "libguile/libpath.h"
7530 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7531 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7532 SCM_SITE_DIR; Install libpath.h among the other include files.
7534 * load.c, load.h (scm_sys_package_data_dir): New function.
7536 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7538 * stacks.h: Bugfix: Don't use tail-array length field as stack
7539 length field! This screwed GC.
7541 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7543 * _scm.h: Added #ifndef around definition of macros min and max.
7545 * __scm.h: Added hooks for threads to plugin to in ints protection
7546 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7547 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7548 the main code in these macros duplicated and spread over multiple
7549 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7550 SCM_THREAD_SWITCHING_CODE.
7552 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7554 * snarf.h: New file.
7555 * guile-snarf.sh: New file.
7556 * Makefile.in (inner_h_files): Added snarf.h
7557 (ancillary, install, uninstall, distclean): Added actions for
7559 (.c.x): Use guile-snarf.
7560 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7561 (gen_c_files): Note that these depend on guile-snarf.
7562 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7563 now in "snarf.h". Added #include "snarf.h" to get them.
7564 * libguile.h: Added #include "snarf.h".
7565 (Patches applied and tweaked by Jim Blandy.)
7567 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7569 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7570 standards suggest against providing prototypes for system
7571 functions. Thanks to Greg Troxel.
7573 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7575 * strports.c (scm_eval_0str): New function.
7576 #include "read.h", to get prototype for scm_read.
7577 * Makefile.in (strports.o): Update dependencies.
7578 * strports.h: New prototype.
7580 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7581 scheme name from "int?" to "integer?". It seems to do the job.
7582 * numbers.h: Rename prototype too.
7583 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7586 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7587 scm_num_eq_p): Rename these according to R4RS conventions: call
7588 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7589 to making libguile R4RS compliant without ice-9...
7591 * load.c (scm_sys_search_load_path): Search for files under all
7592 extensions listed in the %load-extensions variable. If FILENAME
7593 is absolute, return it unchanged, without searching the load path.
7594 (scm_loc_load_extensions): New variable, pointing to
7595 %load-extensions' value cell.
7596 (scm_init_load): Initialize it, and the value it points to.
7597 (scm_primitive_load_path): Improve error reporting.
7599 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7600 of new Scheme variable %load-hook.
7601 (scm_primitive_load): Apply %load-hook to filename.
7603 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7605 * configure.in: add tests for figuring out whether buffered data
7606 is available in a FILE structure, which is needed by char-ready.
7608 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7611 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7612 exceptions using misc_error instead of syserror. It seems a bit
7613 odd to throw an exception if a string can't be found in the
7614 environment, but it's consistent with open-file, stat etc.
7615 (simpos.h): remove sys_ from getenv.
7617 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7618 occurs, throw an error instead of returning errno. Return value
7620 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7622 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7624 * filesys.c (scm_stat2scm): derive file type and permissions from
7625 the stat mode and append them to the returned vector.
7626 There isn't much overhead in doing this and it avoids the need to
7627 work with S_IRUSR et al. in Scheme.
7628 Define symbols scm_sym_regular etc.
7629 (scm_init_filesys): don't intern S_IRUSR etc.
7631 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7632 and s_primitive_load_path.
7634 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7636 * error.h: don't declare error symbols. prototype for scm_misc_error.
7638 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7641 * error.c: use SCM_SYMBOL to set up error keys.
7642 scm_misc_error: new procedure.
7644 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7646 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7647 between `#!' and `!#' is ignored.
7648 (skip_scsh_block_comment): New function.
7650 * feature.c (scm_set_program_arguments): New argument, FIRST.
7651 * feature.h: Update prototype.
7652 * init.c (scm_boot_guile_1): Pass new argument to
7653 scm_set_program_arguments.
7655 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7657 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7658 (scm_boot_guile): Call scm_set_program_arguments here, later than
7659 the old initialization.
7661 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7662 initialization procedure.
7663 - Delete in, out, err arguments; there are other perfectly good
7664 ways to override these when desired.
7665 - Delete result argument; this function shouldn't ever return.
7666 - Rename init_func argument to main_func, for less confusion.
7667 - Delete boot_cmd argument; main_func is more general.
7668 -Add 'closure' argument, to help people pass data to main_func
7669 without resorting to global variables.
7670 - Abort if reentered; don't bother returning an error code.
7671 - Call scm_init_standard_ports to set up the default/current
7672 standard ports; no need to pass them to scm_start_stack.
7673 - Remove code to evaluate the boot_cmd, and start the repl; let
7674 the user do something like that in main_func if they want.
7675 - Remove code to package up a return value; main_func can do any
7677 - Call exit (0), instead of returning.
7678 (scm_start_stack): Don't initialize the I/O ports here; that's
7679 weird. Delete in, out, err arguments. Move guts to
7680 scm_init_standard_ports, scm_stdio_to_port.
7681 (scm_init_standard_ports): New function, to set up current and
7682 default standard ports.
7683 (scm_start_stack, scm_restart_stack): Make these static.
7684 * init.h (scm_boot_guile): Adjust declaration.
7685 (scm_start_stack, scm_restart_stack): Remove externally
7686 visible declarations for these.
7687 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7689 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7690 written out several times in scm_start_stack.
7691 * fports.h: New declaration for the above.
7693 * feature.c (scm_set_program_arguments): New function.
7694 * feature.h: New declaration for the above.
7696 * ports.c: Formatting tweak.
7698 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7700 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7701 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7702 for obtaining the address of a car or cdr field. Motivation:
7703 &SCM_CXR make assumptions about the internal structure of the
7706 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7707 Motivation: see SCM_CXRLOC.
7709 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7710 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7711 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7712 Motivation: Safer use. Some other macros are defined in terms of
7713 these operations. If these are defined using the SCM_SETCXR
7714 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7715 to inefficiency and an <e1> with side-effects could potentially
7716 break. Also, these particular operations are heavily utilized in
7717 the garbage collector. In unoptimized code there will be a
7720 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7721 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7722 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7723 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7724 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7725 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7726 vports.c: Cleaned up use of pairs: Don't make any special
7727 assumptions about the internal structure of selectors and
7728 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7729 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7730 (Among other things, this change makes it easier to build Guile
7731 with certain compilers which have problems with casted lvalues.)
7733 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7735 * stacks.c: Improve selection of relevant stack frames when making
7736 a stack object. Introduce one level of indirection in the stack
7737 object to make it possible to "narrow" to a certain region of the
7738 stack. This facilitates making use of more clever algorithms (not
7739 implemented) for selecting relevant frames and gives a cleaner
7740 design since selection of frames can be done independently of
7741 extraction of frames from the real stack.
7742 (scm_stack_id): Also take #t as argument which means look at
7745 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7746 Turn n_tail into an integer directly representing current number
7747 of frames in stack. Add field tail.
7749 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7751 * debug.c (scm_make_memoized): Made it available at scheme level.
7752 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7753 SCM_NIMP before applying heavier predicates in argument checking.
7754 (scm_local_eval): Also take memoized object as argument.
7756 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7757 aren't created with zero length, but should such a strange
7758 creature suddenly turn up...
7760 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7762 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7763 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7765 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7767 * variable.c (scm_make_variable): Make the name hint optional, as
7769 (anonymous_variable_sym): Renamed from variable_sym. All uses
7772 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7773 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7774 of scm_primitive_load_path was also changed to
7775 "primitive-load-path", from "%try-load-path". Callers changed.
7776 We'd like to respect the convention that a function named
7777 "try-mumble" should behave just like the function called "mumble",
7778 but return #f instead of signalling some error.
7779 * load.h: Rename prototypes.
7781 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7783 * print.c (make_print_state, grow_print_state), print.h: Modified
7784 the print state representation: Don't use a tail array for
7785 recording of circular references. Resizing of the print state
7786 structure invalidates the print state pointer. To avoid passing
7787 around an indirect print state reference to all printing
7788 functions, we instead let the print state reference a resizable
7791 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7793 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7794 Don't crash when passed an improper list terminated by a
7795 non-immediate value.
7797 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7799 Allocate data for structures on an eight-byte boundary, as
7800 required by the tagging system.
7801 * struct.c (alloc_struct): New function.
7802 (scm_make_struct, scm_make_vtable_vtable): Call it.
7803 * struct.h (scm_struct_n_extra_words): Bump to 3.
7804 (scm_struct_i_ptr): New "field".
7805 * gc.c (scm_gc_sweep): When we need to free the data, use the
7806 information stored by alloc_struct to find the beginning of the
7807 block allocated to the structure, so we can free it.
7809 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7811 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7814 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7815 (scm_debug_info): New member: id.
7817 * stacks.c: Stacks are now represented as structs; Stacks have an
7818 id given to them by `start-stack'.
7819 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7821 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7822 Changed stack representation.
7824 * debug.c (scm_procedure_name): Try procedure property `name' for
7825 compiled closures aswell.
7827 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7829 * eval.c: scm_i_name moved to gsubr.c
7830 (scm_m_define): Record names of all kinds of procedure
7831 objects. (Earlier, only closures were recorded.)
7833 * procprop.h: Added declaration of scm_i_name.
7835 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7836 (scm_make_gsubr): Record names of compiled closures.
7838 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7840 * debug.c, debug.h: Removed obsolete code.
7842 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7843 stacks.c: Renamed regs --> scm_contregs.
7845 * print.c (scm_free_print_state): Cleanup print state before
7846 returning it to pool. It is better to do it here than in
7847 scm_prin1 since scm_prin1 is called often.
7849 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7850 s_set_source_property_x): Check that first argument is a pair or a
7853 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7854 scm_i_line, scm_i_column and scm_i_breakpoint global.
7856 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7857 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7860 * debug.h: Added debug object smob declaration and macro
7863 * configure.in: Build with backtrace.o and stacks.o if debug
7866 * Makefile.in: Added entries for new files: backtrace.c,
7867 backtrace.h, stacks.c and stacks.h.
7869 * symbols.c (scm_sym2ovcell): Fixed documentation.
7871 * _scm.h (min, max): Added.
7873 * async.c: Moved `min' macro to _scm.h.
7875 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7876 SCM_BACKTRACE_INDENT.

7882 * print.h: Added selector SCM_PRINT_STATE.
7884 * print.c: New functions: scm_make_print_state,
7885 scm_free_print_state.
7887 * print.h: Added declarations for scm_make_print_state,
7888 scm_free_print_state.
7890 * debug.c (scm_m_start_stack): New acro.
7892 * debug.h: Small cleanup.
7894 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7922 More prototype-related changes from Marius Vollmer:
7923 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7924 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7925 * ports.h (ptobfuns): Added prototypes. This means some casting in
7927 * fports.c: Added casts for initializations, since the functions
7928 are defined to take FILE * as their stream argument, not SCM.
7929 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7930 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7931 to `char *str_data' to conform to prototype.
7933 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7935 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7937 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7939 * stime.c, stime.h: use SCM_P method.
7941 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7943 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7944 be given at least two arguments. Insist that lst's last element
7945 be a list, but don't make any requirements of its predecessors.
7947 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7949 * eval.c (scm_nconc2last): Revert last change; there seems to be
7950 other stuff going on here.
7952 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7954 * eval.c (scm_nconc2last): Make sure that each element of lst
7955 (which is a list of argument lists, except for the tail) is a
7956 proper list, i.e., finite and terminated by '().
7958 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7960 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7963 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7964 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7967 * vectors.c (scm_make_vector): Fill vectors with the undefined
7968 value, to help make Guile Scheme code more portable to other
7971 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7972 * symbols.h, tags.h: Doc fixes.
7974 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7976 * async.c (scm_take_signal): Doc fixes.
7978 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7980 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7981 want to subtract it from the modulus; we just want to leave it
7984 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7986 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7989 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7991 * throw.c (scm_catch_apply): Finished implementation of
7994 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7996 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7998 (scm_init_filesys): set "i/o-extensions" feature.
8001 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
8003 * Makefile.in (root.o): Correct dependencies.
8005 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
8007 * Makefile.in: Added dependency entry for root.o.
8009 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
8010 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
8012 * init.c (scm_start_stack): Set initial root continuation number
8015 * procs.c: New function: scm_thunk_p.
8017 * procs.h: Added declarations of scm_thunk_p.
8019 * root.c: Renamed `call-with-new-root' -->
8020 `call-with-dynamic-root'.
8021 (cwdr): Removed allocation of new root state. This should be done
8022 separately by use of scm_make_root.
8023 (scm_apply_with_dynamic_root): New function: Does what it
8024 sounds like. Needed when spawning threads.
8026 * root.h: Added member last_debug_frame to root state.
8027 Added #include "libguile/debug.h"
8029 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
8030 arguments. The motivation is that code in root.c needs catch
8031 functionality, and we want to avoid code duplication.
8032 New functions: scm_catch, scm_lazy_catch. These are wrappers for
8033 scm_catch_apply. scm_lazy_catch is intended to introduce catch
8034 handlers that run without popping the stack into the dynwind
8037 * throw.h: Added prototypes for scm_catch_apply and
8040 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8042 * root.h (scm_root, scm_set_root): Decouple thread support details
8043 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
8044 SCM_SET_THREAD_LOCAL_DATA.
8046 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
8047 and tortoise scanning loop.
8049 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
8051 * Makefile.in: Rebuild dependencies.
8053 * libguile.h: #include "libguile/print.h" before "smob.h", since
8054 the latter uses the print_state structure.
8056 * throw.c (scm_ithrow): Use the correct variable when checking to
8057 see if a given element of scm_dynwinds is a valid catch.
8059 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
8060 structure, abort; don't just silently ignore the garbage.
8062 * _scm.h: #include "print.h" here, since it seems to be used just
8064 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
8065 strports.c, unif.h: Don't #include "print.h".
8067 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8069 * feature.h (scm_loc_features): Removed external declaration.
8070 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
8072 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8074 * feature.c (scm_init_feature): Added threads feature (needs to be
8075 initialized here, since features doesn't exist when
8076 scm_init_threads is called).
8078 * libguile.h: Added #include "libguile/../threads/threads.h".
8079 (This is a kludge to get thread support working. This should be
8082 * configure.in, acconfig.h: Added flags for thread support.
8084 * scmsigs.c: Define `signal' to be `pthread_signal' if using
8087 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
8088 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
8091 * _scm.h: Added conditional #include "threads.h"
8093 * __scm.h (SCM_ASYNC_TICK): Added call to macro
8094 SCM_THREADS_SWITCHING_CODE.
8096 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
8097 allocate the basic dynamic root object.
8098 (scm_boot_guile): Added call to scm_init_root.
8100 * root.c, root.h: Added root smob.
8101 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
8102 functions: Implements dynamic roots mostly according to spec in
8103 SCM manual. Main difference is that the second argument is a
8104 throw handler rather than an error "thunk".
8106 * root.h: Added declaration of scm_init_root.
8108 * root.c: Added #include "genio.h", #include "smob.h", #include
8109 "pairs.h", #include "throw.h", #include "dynwind.h", #include
8111 (scm_init_root): Added #include "root.x".
8113 * throw.c: Added #include "stackchk.h"
8114 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
8115 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
8116 can be used in scm_call_with_new_root; Added reenabling of stack
8117 checking when catching a throw.
8119 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
8121 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
8123 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
8124 element is not found, as per R4RS.
8126 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8128 * list.c: Doc fixes throughout.
8130 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
8132 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
8133 declare the char * to be const. Avoids a warning in rgx.c.
8135 * ports.h: spelling fix.
8137 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
8140 * load.c (scm_sys_try_load_path): throw an error if file not found
8141 (like it says it in NEWS).
8143 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8145 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
8146 PROPS slot to '(), not #f; it's an empty alist.
8148 * throw.h, throw.c: Use SCM_P instead of #if hair.
8150 Remove special support for uncaught throws; see throw.c for
8152 * throw.c (uncaught_throw): New function.
8153 (scm_ithrow): Call uncaught_throw if we don't find a throw
8154 target; don't mess with scm_bad_throw_vcell.
8155 (scm_bad_throw_vcell): Variable deleted.
8156 (scm_init_throw): Don't initialize it.
8158 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
8161 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
8163 * numbers.c (scm_istr2int): If the number is short (as most
8164 numbers are), just call scm_small_istr2int to deal with it.
8165 (scm_small_istr2int): New function, created by un-#ifdefing the
8166 non-bignum version of scm_istr2int and renaming it.
8168 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
8170 * load.c (scm_sys_try_load): don't check whether value returned
8171 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
8172 Change the Scheme name from %try-load to primitive-load.
8174 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
8175 Can avoid passing a message, allowing it to be derived in the
8176 error handler (e.g., if we want to throw to the key both from
8179 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
8181 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
8182 references now have a new appearance which is more compact and
8183 also gives a clue about what the target of the reference is.
8184 By setting parameters in the print state, more fancy printing can
8185 be achieved. This is used by the (not yet commited) backtrace
8188 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
8190 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
8193 * print.c: Added #include "struct.h". Removed function
8196 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
8197 scm_iprin1. Removed prototype for scm_prlist.
8199 * arbiters.c (prinarb),
8200 async.c (print_async),
8201 debug.c (prindebugobj, prinmemoized),
8202 eval.c (prinprom, prinmacro),
8203 filesys.c (scm_fd_print, scm_dir_print),
8205 mallocs.c (prinmalloc),
8206 numbers.c, numbers.h (scm_floprint, scm_bigprint),
8207 smob.h (scm_smobfuns),
8208 srcprop.c (prinsrcprops),
8210 unif.c, unif.h (scm_raprin1, rapr1),
8211 variable.c (prin_var): Changed argument `int writing' to
8212 `scm_print_state *pstate'.
8214 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
8215 that it will be called before scm_init_print.
8217 * print.c (scm_prin1): Print states are now allocated when calling
8218 scm_prin1 and then passed around to all printing functions as an
8219 argument. A cache `print_state_pool' enables reuse of print
8221 (scm_make_print_state): New function.
8222 (scm_iprin1): Adaption to print states.
8223 (scm_iprlist): An initial "hare and tortoise" scan brings down
8224 time complexity to O (depth * N). (Better time complexity will be
8225 achieved when the printing code is completely rewritten.)
8227 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
8229 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
8230 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
8231 it gets done whether or not the cache variable has a value.
8233 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8235 Distinguish #f and ().
8236 * __scm.h: #undef SICP.
8237 * pairs.h (SCM_EOL): Delete this definition, equating it with
8239 * tags.h (SCM_EOL): Give it a new definition here; I think I found
8240 the value it used to have. Doc fixes, too.
8242 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
8244 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
8245 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
8246 Lord's implementation of structs, allowing for tail arrays as
8247 described in the manual. Also fixed some bugs. (Both the interface
8248 and the implementation should be improved.)
8250 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
8252 * print.c, print.h: Closures now print like #<procedure foo (x)>.
8253 People who whish to see the source can do `(print-enable 'source)'.
8254 Removed #ifdef DEBUG_EXTENSIONS.
8256 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8258 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
8259 integer (assuming for now accepting an integer is a good thing).
8261 * error.c, fports.c: replace use of %S in lgh_error args with %s.
8262 %S will be used instead for write'ing arguments.
8264 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
8265 asserts. fix a few other asserts.
8266 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
8267 scm_uniform_vector_ref, scm_array_set_x,
8268 scm_dimensions_to_unform_array): change args in
8269 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
8270 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
8271 scm_substring_fill_x): likewise.
8272 gsubr.c (scm_gsubr_apply): likewise.
8273 eval.c (SCM_APPLY): likewise.
8275 * eval.c (4 places): replace scm_everr with lgh_error or
8278 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
8279 scm_memory_error): new procedures.
8280 scm_everr: deleted. can use scm_wta, dropping first two args.
8281 scm_error: convert NULL subr to SCM_BOOL_F.
8283 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
8286 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
8289 * error.c, error.h: new error keys: scm_arg_type_key,
8290 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
8292 scm_wta: reimplement using lgh_error instead of scm_everr.
8294 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
8296 * gdbint.c: scm_lread now has one more argument.
8298 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
8299 scm_port_\1; Added mutator scm_set_port_filename_x (used when
8300 loading source from non-file ports, which, e. g., happens when
8301 using the Emacs interface).
8303 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
8306 * read.c: Added code for recording of positions of source code
8307 expressions; New functions: recsexpr, scm_lreadrecparen;
8308 _scm_make_srcprops --> scm_make_srcprops
8309 (scm_flush_ws): Removed updating of positions counters. This work
8310 is already done by scm_gen_getc
8312 * read.h: Added prototype for scm_lreadrecparen
8314 * print.c: Added #include "alist.h"
8316 * eval.c: Added #include "hash.h"
8318 * eq.c: Added #include "ramap.h"
8320 * options.c: Documentation fixes.
8322 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
8323 (scm_init_srcprop): Adjusted size of initial source-whash. Name
8324 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
8325 --> scm_make_srcprops
8327 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
8328 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
8329 function calls in the definition of the whash access macros.
8331 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
8333 * init.c (scm_boot_guile): Add level of indirection to
8334 scm_boot_guile_1() to ensure that stack base pointer is properly
8335 initialized. There was no guarantee that variable i was the
8336 highest/lowest variable on stack (i.e. the call frame of
8337 scm_boot_guile was not completely protected from gc).
8339 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
8341 * ports.h (scm_port_table): put back file_name, it will be used to
8342 support debugging. Undo related changes in fports.c, ioext.c,
8345 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8347 * ports.h (scm_port_table): remove file_name member for now, it seems
8349 * fports.c (scm_open_file): don't set file_name in PTAB.
8350 (prinfport): don't use file_name in PTAB.
8351 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8352 * ports.c (scm_add_to_port_table): don't intialize file_name.
8353 (scm_port_file_name): remove for now.
8354 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8356 * fports.h (scm_mkfile): prototype deleted.
8357 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8359 * debug.c, unif.c: use scm_out_of_range instead of
8360 wta for range errors (ASSERT still needs work).
8362 * error.c, error.h (scm_out_of_range): new procedure.
8364 * error.c, error.h (scm_out_of_range_key): new key.
8366 * posix.c (scm_sync): #else was missing.
8368 * error.c, error.h: append _key to names scm_num_overflow and
8371 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8372 of consing an empty list.
8373 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8374 of macros, saves code and string space.
8375 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8376 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8377 lower case. Rename scm_syserror_m to scm_syserror_msg.
8378 error.h: prototypes for new procedures.
8380 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8382 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8384 * error.c, error.h: setup scm_num_overflow key.
8386 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8387 Remove definition of SCM_OVSCM_FLOW.
8389 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8391 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8392 explicit message and args.
8394 * error.c, error.h, __scm.h: change system_error_sym to
8397 * error.c (system_error_sym): remove leading %% from the Scheme name
8400 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8402 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8404 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8405 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8406 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8407 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8408 renamed. (These were introduced by unsupervised name
8411 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8413 * print.c: Added code for detection of circular references during
8414 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8415 a hook for printing of closures (accessible via print options).
8416 This leads to a split of calls to scm_iprin1 into two classes:
8417 elementary print operations (e. g. the code which prints a smob)
8418 still use scm_iprin1 while top level calls (like scm_display) use
8419 scm_prin1. scm_prin1 begins by clearing the data structure used
8420 to record reference information.
8422 * print.h: Added declarations of scm_prin1 and scm_prlist.
8424 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8426 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8428 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8430 * error.c (err_head): scm_iprin1 --> scm_prin1
8432 * debug.c: Adjusted header comment.
8436 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8438 * strerror.c: Doc fix.
8440 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8442 * gdbint.c (gdb_read): Now possible to run during GC.
8443 (unmark_port, remark_port): New functions.
8445 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8447 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8448 of allocating a new string object. Also, increase size by
8449 the factor 2 instead of 1.5.
8451 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8453 * __scm.h (SCM_P): Corrected to run under traditional C.
8455 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8458 * async.c: Calls to scm_sysintern corrected.
8460 * async.h (scm_async_clock): Redundant declaration removed.
8462 * continuations.c (scm_dynthrow): Redundant declaration removed.
8464 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8465 Definition typos corrected.
8467 * debug.h: Missing declarations of functions in debug.c added
8470 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8471 Missing declarations to functions in eval.c added.
8473 * filesys.c: Possibly uninitialized variable rv.
8475 * gc.h (scm_object_addr, scm_unhash_name): Missing
8476 declarations of functions defined in gc.c added.
8478 * genio.c: Possible typos str_data -> wstr_data. ???
8480 * genio.c: Possibly unintended shadowing of local variable
8481 `int c' (gotos out of scope of inner `c'). ???
8483 * init.c: Uninitialized `SCM last' may be used.
8485 * ioext.h: (scm_sys_isatty_p): Typo.
8487 * list.h (scm_list_head): Missing prototype for function in
8490 * numbers.c (scm_two_doubles): Changed from extern to static
8491 (is used only within numbers.c).
8493 * numbers.h: Repeated declarations removed.
8495 * ports.h (scm_close_all_ports_except): Declaration for the
8496 function defined in ports.c added.
8498 * posix.h: Missing declarations added.
8500 * procs.h (scm_make_subr_opt): Missing declaration added.
8502 * socket.h (scm_sys_gethost): Missing declaration added.
8504 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8506 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8507 Missing declarations added.
8509 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8511 * struct.c: Uninitialized variable `SCM answer' may be used.
8513 * unif.c (l2ra): Declaration prototype.
8515 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8516 defined in ramap.c).
8518 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8519 Redundant declarations removed (they are in ramap.h).
8521 * variable.h (scm_make_udvariable,
8522 scm_make_undefined_variable): Declaration corrected to
8523 correspond variable.c.
8525 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8526 Missing declarations added.
8528 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8530 * Makefile.in (distclean): Don't forget to delete fd.h.
8532 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8534 * fd.h.in, tags.h: Trivial cleanups.
8536 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8537 marksweep.h just declared functions from gc.c.
8538 * gc.h, libguile.h: Don't #include "marksweep.h".
8539 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8540 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8541 dependencies updated.
8543 * libguile.h: Don't #include "files.h"; it's been deleted.
8545 * files.c (scm_sys_delete_file): Moved to filesys.c.
8546 File is now empty; deleted.
8548 * filesys.c: scm_sys_delete_file is now here. Remove
8549 #if's; they seem to rely on remnants of an old portability
8550 regimen. If the problems come up again, solve them properly,
8551 using autoconf. Specifically: Don't test M_SYSV, and #define
8552 remove to be unlink if it's #defined; don't use remove just
8553 because HAVE_STDC_HEADERS is #defined.
8554 * filesys.h: Add declarations for scm_sys_delete_file.
8555 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8556 files.o, files.h, files.c, and files.x.
8557 * init.c: Don't #include "files.h", and don't call scm_init_files.
8559 Use SCM_P instead of PROTO; the latter intrudes on the user's
8561 * params.h: Deleted; definition of SCM_P moved to...
8562 * __scm.h: ... here, where it replaces PROTO macro.
8563 * libguile.h, smob.h: Don't #include "params.h".
8564 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8565 smob.h: Fix prototypes accordingly.
8566 * Makefile.in: Update dependencies.
8567 (inner_h_files): Remove params.h.
8569 * gc.c: #include "gc.h"; every module should include its header,
8570 to let the compiler cross-check the declarations against the
8573 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8574 simpos.h: #include "libguile/__scm.h".
8576 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8578 * init.c: Don't forget to #include smob.h and init.h.
8579 * Makefile.in: Dependencies updated.
8581 * smob.h: Use PROTO instead of #if __STDC__.
8583 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8585 * __scm.h: Doc fixes.
8587 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8588 <angles>; this allows `make depends' to work properly.
8590 * libguile.h: #include smob.h and pairs.h before the others; they
8591 define typedefs used by other headers.
8593 C files should #include only the header files they need, not
8594 libguile.h (which #includes all the header files); the pointless
8595 recompilation was wasting my time.
8596 * Makefile.in (all .o dependency lists): Regenerated.
8597 * libguile.h: Don't try to get a definition for size_t here...
8598 * __scm.h: Do it here.
8599 * _scm.h: Since this is the internal libguile header, put things
8600 here that all (or a majority) of the libguile files will want.
8601 Don't #include <libguile.h> here; that generates dependencies on
8602 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8603 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8604 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8701 * weaks.c: Get "weaks.h".
8703 * stackchk.h: #include "libguile/debug.h",
8705 * print.h, read.h: #include "options.h", since everyone who uses
8706 either of these files will need that.
8708 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8709 anyone who uses this file will need them to define the smob
8710 printing functions. Also, get markers.h, since people will need
8711 to #define the mark functions.
8713 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8714 * ports.h: ... to here.
8716 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8717 don't rely on archaic C default type rules.
8719 * fports.h: #include "libguile/ports.h", since you need that in
8720 order to parse this.
8722 * genio.h: #include "libguile/print.h", because you need that to
8723 parse this; don't bother #including "ports.h", since print.h gets
8726 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8728 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8729 this; it's now a reference to an element of *scm_root.
8731 * debug.h: Don't #include "options.h"; the compiler won't be able
8732 to find that once the headers are installed; instead, #include
8733 "libguile/options.h".
8734 * gc.h: Same, with marksweep.h.
8735 * mbstrings.h: Same, with symbols.h.
8736 * scmhob.h: Same, with _scm.h.
8737 * smob.h: Same, with params.h.
8739 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8740 C files; there's no need for this, and it forces recompilations
8743 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8745 * error.c (scm_error): declare scm_error_callback.
8747 * error.h: prototype for scm_error_callback.
8749 * __scm.h: define lgh_error.
8750 (SCM_SYSERROR): redefine using lgh_error.
8752 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8754 * error.c (scm_error): new procedure.
8756 * error.h: prototype for scm_error.
8758 * Makefile.in (install): install scmconfig.h from the current
8759 directory, not $(srcdir).
8761 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8763 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,

8771 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8772 vports.h, weaks.h: #include "libguile/__scm.h", not
8773 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8774 dependencies are within libguile properly.
8776 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8778 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8779 when scmconfig.h doesn't exist.
8781 * load.c (scm_sys_try_load): Correct spelling.
8783 * feature.c (scm_loc_features): Make this static.
8785 * Makefile.in (libpath.h): Omit trailing slash from path. We
8786 shouldn't require it of users, so why put it here?
8788 Move code to initialize and search %load-path from ice-9 to C
8789 code, so we can use the load-path to find the ice-9 boot code;
8790 this makes it easier to run Guile without installing it. See
8791 corresponding changes in guile/Makefile.in.
8792 * feature.c: Move stuff concerned with the load path to load.c.
8793 (scm_compiled_library_path): Deleted.
8794 Don't #include libpath.h here.
8795 * feature.h: Don't mention scm_compiled_library_path.
8796 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8797 <sys/stat.h>, and <unistd.h> (if present).
8798 (R_OK): #define if the system hasn't deigned to.
8799 (scm_loc_load_path): New variable.
8800 (scm_init_load_path, scm_sys_search_load_path,
8801 scm_sys_try_load_path): New functions.
8802 (scm_init_load): Initialize scm_loc_load_path to point to the
8803 value cell of the Scheme %load-path variable.
8804 * load.h: Add declarations for scm_sys_search_load_path,
8805 scm_sys_try_load_path.
8806 * init.c: Call scm_init_load_path.
8807 * Makefile.in (feature.o, load.o): Dependencies updated.
8809 * load.c, load.h: Rewrite using PROTO macro.
8811 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8813 * gc.c (scm_cellp): New function: C predicate to determine if an
8814 SCM value can be regarded as a pointer to a cell on the heap.
8816 * gc.h: Added declaration of scm_cellp.
8818 * gdb_interface.h: New file: The GDB interface header from the GDB
8821 * gdbint.c: New file: GDB interface.
8823 * gdbint.h: New file: GDB interface.
8825 * libguile.h: Added #include <libguile/gdbint.h>.
8827 * init.c (scm_boot_guile): Added scm_init_gdbint.
8829 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8830 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8831 found if object files and source are kept separate).
8833 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8835 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8837 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8839 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8840 TK_SRC_DIR; they're not relevant any more.
8842 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8843 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8845 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8847 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8848 search path, so we can find the <libguile/MUMBLE.h> headers.
8850 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8852 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8853 implicit in the .c.o rule.
8854 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8857 Put the library path in a header file, instead of passing it on
8858 the command line in every compilation.
8859 * Makefile.in (libpath.h): New target.
8860 (feature.o): Depend on libpath.h.
8861 (clean): Delete libpath.h.
8862 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8863 * feature.c: ... #include "libpath.h" here.
8864 * .cvsignore: Ignore libpath.h.
8866 Don't install the unwashed masses of Guile header files in the
8867 main #include path; put most of them in a subdirectory called
8868 'libguile'. This avoids naming conflicts between Guile header
8869 files and system header files (of which there were a few).
8870 * Makefile.in (pkgincludedir): Deleted.
8871 (innerincludedir): New variable; this and $(includedir) are enough.
8872 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8873 (installed_h_files): Divide this up. Now this variable lists
8874 those header files which should go into $(includedir) (i.e. appear
8875 directly in the #include path), and ...
8876 (inner_h_files): ... this new variable says which files appear in
8877 a subdirectory, and are referred to as <libguile/mumble.h>.
8878 (h_files): List them both.
8879 (install): Create innerincludedir, not pkgincludedir. Put
8880 the installed_h_files and inner_h_files in their proper places.
8881 (uninstall): Corresponding changes.
8882 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8883 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8884 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8885 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8886 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8887 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8888 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8889 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8890 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8891 vports.h, weaks.h: Find __scm.h in its new location.
8892 * __scm.h: Find scmconfig.h and tags.h in their new locations
8893 (they're both "inner" files).
8895 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8897 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8899 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8901 * posix.c: Doc fixes.
8903 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8905 * socket.c: Don't include a prototype for inet_aton; just use a
8906 K&R style declaration, to avoid warnings but minimize the chance
8907 of conflicts with the system.
8909 On NextStep, <utime.h> doesn't define struct utime, unless we
8910 #define _POSIX_SOURCE before #including it.
8911 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8912 * acconfig.h: New comment text for above CPP symbol.
8913 * configure.in: Call it.
8914 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8916 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8918 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8919 testing for __EMX__.
8921 * posix.c: #include <libc.h>, if it exists.
8923 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8924 don't even know if the latter exists.
8926 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8927 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8928 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8930 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8932 (scm_init_posix): Use them when initializing the Scheme constants
8935 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8937 * Makefile.in (libdir, includedir, bindir): Use the
8938 autoconf-supplied values, instead of deriving them ourselves.
8939 (pkgincludedir, datadir, pkgdatadir): New variables.
8940 (install, uninstall): Put the header files in a special
8941 subdirectory, not in the main search path.
8943 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8944 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8946 * Makefile.in (IMPLPATH): Deleted; never used.
8948 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8949 on the Tcl/Tk source any more.
8950 (INCLUDE_CFLAGS): Remove references to the above.
8952 * Makefile.in (version.o): Corrected dependencies.
8954 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8956 * libguile.h: #include "version.h"
8958 * init.c (scm_boot_guile): Call scm_init_version.
8959 * gscm.c (gscm_run_scm): Call scm_init_version.
8961 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8962 GUILE_VERSION): AC_DEFINE these.
8963 (acconfig.h): #undef the above symbols.
8965 * Makefile.in (libobjs): Add version.o.
8966 (installed_h_files): Add version.h.
8967 (c_files): Add version.c.
8968 (gen_c_files): Add version.x.
8969 (version.o): New rule.
8970 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8971 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8972 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8973 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8974 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8975 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8976 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8977 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8978 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8979 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8980 weaks.o): Add version.h to dependency lists.
8981 (markers.o): Remove duplicate rule.
8983 * version.h: New file.
8985 * version.c: New file.
8987 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8989 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8990 array; use it appropriately. Since GCC is quite happy to
8991 subscript functions, it never warned us about this; we should use
8992 -Wpointer-arith in the future. I guess we never tested
8995 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8997 * socket.c: Doc and copyright fixes.
8999 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9001 * debug.c: Fixed and improved gdb support.
9003 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9005 * socket.c: Added declaration of inet_aton to avoid compiler
9006 warning. (Hope this solution is correct.)
9008 * stime.c: Added declaration of ftime. (This is missing in
9011 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
9013 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9015 * Makefile.in (c_files): add strerror.c.
9017 * strerror.c: new file from Emacs' sysdep.c.
9018 maybe configure should also check for sys_errlist.
9020 * configure.in (AC_REPLACE_FUNCS): add strerror.
9022 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9024 * debug.c (scm_init_debug): Added initialization for
9025 scm_evaluator_traps.
9027 * debug.h, debug.c: Various name changes.
9028 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
9029 "debug-options-interface". See commentary in options.c.
9031 * options.h, options.c: Options now have documentation strings.
9032 Also added a long explanatory commentary.
9034 * eval.c, print.h, print.c, read.h, read.c: Modifications to
9037 * gscm.c, init.c, root.c, throw.c: Bug fixes:
9038 last_debug_info_frame is now updated in all cases.
9040 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
9043 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9045 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
9046 Added option STACK_CHECKING.
9048 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
9050 * Makefile.in: Added {debug,options,srcprop}.{h,c}
9052 * __scm.h: Removed symbols for debugging support.
9054 * acconfig.h: Added symbols for debugging support.
9056 * configure.in: Added user option for debugging support.
9057 --enable-debug will include the debugging code into libguile.a.
9059 * continuations.c (scm_make_cont): Enlarged the #if 0 around
9060 scm_relocate_chunk_to_heap.
9062 * debug.c: New file: low-level debugging support. It also
9063 includes support for debugging with gdb. (The extensions to gdb
9064 are written by Per Bothner at Cygnus.)
9066 * debug.h: New file: low-level debugging support.
9068 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
9069 argument pairs. Extensive modifications to the debugging
9070 evaluator. Added "SECTION:" commentaries to clarify what happens
9071 when, during double compilation. Renamed EVALIMP --> EVALIM.
9072 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
9073 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
9074 the beginning of the file. New procedure: scm_unmemocopy.
9075 Added some global state variables needed by the debugging
9076 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
9077 check_entry, check_apply, check_exit, debug_options and
9078 evaluator_traps. New acro: undefine.
9080 * eval.h: Renamed EVAL --> XEVAL.
9082 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
9083 --> scm_make_weak_key_hash_table.
9085 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
9086 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
9088 * libguile.h: Conditionally include debug.h
9090 * objprop.c (scm_object_properties, scm_set_object_properties_x):
9091 scm_object_properties shouldn't return handle. `handle' now gets
9092 initialized in scm_set_object_properties_x. scm_object_properties
9093 doesn't any longer create an entry in scm_object_whash.
9095 * options.c: New file: handling of run time options.
9097 * options.h: New file: handling of run time options.
9099 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
9101 * print.c: New procedure: scm_print_options
9103 * print.h: Defines for print options.
9105 * read.c: New procedure: scm_read_options
9107 * read.h: Defines for reader options.
9109 * root.h: Added scm_source_whash among scm_sys_protects.
9111 * srcprop.c: New file: source properties.
9113 * srcprop.h: New file: source properties.
9115 * throw.c (jbsmob): Jump buffers are now correctly allocated.
9116 (Bug found by A. Green.)
9118 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9120 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9122 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
9124 * libguile.h: #include "objprop.h"; I guess this was forgotten.
9126 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
9127 and should be called by the final client.
9129 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
9131 * gc.h: Use the PROTO macro when declaring functions.
9132 * gc.c: Use the PROTO macro when declaring static functions.
9133 Remove the CPP hair around function definitions.
9135 * gc.c (scm_init_storage): Initialize scm_asyncs.
9137 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
9138 preprocessor symbol; "__scm.h" is where it might get #defined.
9139 * __scm.h: Similar: #include <scmconfig.h> before testing
9142 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
9144 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
9146 * init.c (scm_boot_guile): Add init_func argument; call
9147 (*init_func) instead of calling scm_appinit; it's ucky to
9148 hard-code names for the user's procedures.
9149 * init.h (scm_boot_guile): Adjust declaration.
9151 * __scm.h (PROTO): New macro, for declaring functions with
9154 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
9155 eliminate all the __STDC__ conditionals.
9156 (scm_boot_guile): Add declaration.
9157 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
9158 Remove __STDC__ conditionals around function definitions; the
9159 declarations in init.h will provide the same information, more
9162 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
9163 complain about it in the error message; the error message is
9164 adequate without that note, and there's nothing the user can do
9167 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
9169 * Makefile.in (ancillary): Drop def.sed.
9171 * posix.c (scm_init_posix): Use numeric values, rather than
9172 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
9173 F_OK. The symbols aren't available on some systems, and I'm
9174 pretty sure their values are fixed by common widespread practice.
9175 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
9177 More functions unavailable on some systems.
9178 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
9179 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
9181 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9182 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
9183 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
9184 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
9185 stub that signals an error as the #else.
9187 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
9189 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
9191 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
9193 * unif.c: include ramap.h.
9195 * read.c (endif): case_insensative_p renamed case_insensitive_p.
9197 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
9199 * ports.c: include sys/ioctl.h.
9201 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
9203 * configure.in: check for sys/ioctl.h.
9205 * ports.c: include <malloc.h> not "malloc.h".
9207 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9209 * fports.c: remove ttyname and tmpnam declarations.
9211 * posix.c: fewer ttyname declarations.
9213 * fports.c: include <string.h> not "string.h".
9215 * init.c, ioext.c: include string.h and unistd.h.
9217 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9219 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
9220 genio.c, simpos.c, vports.c: include string.h.
9222 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
9224 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
9226 (scm_addr_buffer_size): change type from scm_sizet to int.
9227 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
9228 from scm_sizet to int.
9230 * error.c: include unistd.h.
9232 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
9235 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
9237 * __scm.hd, def.sed: deleted.
9239 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
9241 Changes for NeXT, suggested by Robert Brown.
9242 * configure.in: Call AC_TYPE_MODE_T.
9243 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
9244 NeXT. Put header file list in alphabetical order.
9245 * configure, scmconfig.h.in: Regenerated.
9246 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
9248 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
9251 * acconfig.h: New file, providing documentation for the CPP
9252 symbols defined in configure.in
9253 * acconfig-1.5.h: Removed; superceded by the above.
9255 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
9257 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
9259 * fports.c (scm_open_file): don't return #f, throw error.
9261 * ioext.c (fileno): renamed from %fileno.
9262 (soft-fileno): deleted.
9264 * ports.c (scm_port_revealed): don't need to check for -1 from
9266 (scm_set_port_revealed_x): return unspecified, not #f.
9268 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
9270 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
9272 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
9274 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
9276 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
9278 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
9279 This is necessary on Ultrix, and doesn't hurt portability.
9281 * Makefile.in (dist-dir): New target, implementing a new dist system.
9282 (installed_h_files): Put in alphabetical order.
9283 Remove duplicate entries for markers.h and unif.h.
9284 (c_files): Remove duplicate entries for markers.c.
9285 (ancillary): Renamed from anillery; all uses changed. Remove

9289 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
9291 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
9292 every if must have an else, or else the whole command has a

9362 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
9364 * gscm.h: gscm_mkarray eliminated (presumably was not being used

9371 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
9373 * ports.c: removed functions relating to the mapping between ports

9382 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
9383 handled correctly (SCM_FREEP was applied to them) -- test for

9552 initialization to fix a race condition.
9554 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

9581 The weird symbol syntax is also a bit bogus (emacs doesn't quite
