+
+ * threads.c (fat_mutex_lock): Resolve a deadlock caused by not
+ checking mutex state after calling `SCM_TICK'.
+
+2008-08-20 Ludovic Courtès <ludo@gnu.org>
+
+ * eval.c, filesys.c, gc.c, numbers.c, posix.c, srfi-14.c,
+ stime.c, threads.c: Don't define `_GNU_SOURCE' explicitly as
+ it's now defined in <config.h> thanks to
+ `AC_USE_SYSTEM_EXTENSIONS'.
+
+2008-08-19 Han-Wen Nienhuys <hanwen@lilypond.org>
+ Ludovic Courtès <ludo@gnu.org>
+
+ * goops.c (scm_init_goops_builtins, go_to_hell): Fix allocation
+ of `hell' by passing "hell_size * sizeof (*hell)" instead of
+ "hell_size" to `scm_malloc ()' and `scm_realloc ()'.
+
+2008-08-02 Neil Jerram <neil@ossau.uklinux.net>
+
+ * numbers.c (scm_rationalize): Update docstring to match the
+ manual (which is more correct). Change argument "err" to "eps",
+ also to match the manual.
+
+2008-07-17 Neil Jerram <neil@ossau.uklinux.net>
+
+ From Thiemo Seufer <ths@networkno.de>:
+
+ * gc_os_dep.c (CPP_WORDSZ, ALIGN_DOUBLE, DATAEND,
+ DYNAMIC_LOADING): Added #defines.
+ (_fdata, _end): Added declarations.
+ (DATASTART): Use _fdata instead of __data_start.
+ (STACKBOTTOM): Changed from 0x80000000 to 0x7fff8000.
+
+2008-07-16 Ludovic Courtès <ludo@gnu.org>
+
+ * gen-scmconfig.h.in (SCM_I_GSC_HAVE_STRUCT_DIRENT64): New.
+ * gen-scmconfig.c (main): Produce definitions of
+ `SCM_HAVE_STRUCT_DIRENT64' and `SCM_HAVE_READDIR64_R'.
+ * _scm.h (dirent_or_dirent64): Depend on
+ `SCM_HAVE_STRUCT_DIRENT64', for the sake of HP-UX 11.11.
+ (readdir_r_or_readdir64_r): Depend on `SCM_HAVE_READDIR64_R',
+ for HP-UX 11.11.
+
+2008-07-05 Ludovic Courtès <ludo@gnu.org>
+
+ * strings.c (scm_c_symbol_length): New function.
+ * strings.h (scm_c_symbol_length): New declaration.
+
+2008-06-28 Ludovic Courtès <ludo@gnu.org>
+
+ * Makefile.am (INCLUDES): Renamed to...
+ (AM_CPPFLAGS): this, to match current Automake conventions.
+ Users updated.
+
+ * tags.h (SCM_UNPACK): Disable type-checking for `__DECC' and
+ `__HP_cc'. Reported by Peter O'Gorman <pogma@thewrittenword.com>.
+
+2008-06-02 Ludovic Courtès <ludo@gnu.org>
+
+ * deprecated.c (maybe_close_port): Rename EXCEPT to EXCEPT_SET
+ to workaround `#define except' on Tru64. Reported by Peter
+ O'Gorman <pogma@thewrittenword.com>.
+
+2008-05-12 Neil Jerram <neil@ossau.uklinux.net>
+
+ * discouraged.c: Expand DEFFROM and DEFTO macros, to avoid
+ compiler warnings about excess semicolons. (Reported by Didier
+ Godefroy.)
+
+2008-05-08 Neil Jerram <neil@ossau.uklinux.net>
+
+ * throw.c (scm_ithrow): For IA64 add a return statement, to
+ appease GCC.
+
+ * threads.h (scm_i_thread): New IA64 fields:
+ register_backing_store_base and pending_rbs_continuation.
+
+ * threads.c (guilify_self_1): For IA64: cap RBS base address at
+ the current value of scm_ia64_ar_bsp, and store the capped value
+ in thread state.
+ (SCM_MARK_BACKING_STORE): Use thread->register_backing_store_base
+ instead of scm_ia64_register_backing_store_base().
+ (scm_threads_mark_stacks): Add "&" in "&t->regs", so that the code
+ works both for jmp_buf defined as an array, and jmp_buf defined as
+ a struct.
+
+ * continuations.h (scm_t_contregs): Remove `fresh' and `ctx'
+ fields; these are now inside the IA64 definition of `jmp_buf'.
+
+ * continuations.c (scm_make_continuation): Simplify, by moving
+ some of the IA64 code inside the definition of "setjmp", and by
+ some obvious commonizations. For IA64 register backing store
+ (RBS) stack base, use thread->register_backing_store_base instead
+ of scm_ia64_register_backing_store_base().
+ (copy_stack): For IA64, store pointer to continuation being
+ invoked in thread state, so we can restore the continuation's RBS
+ stack just before the next setcontext call.
+ (copy_stack_and_call): Don't restore RBS stack explicitly here.
+ It will be restored, if appropriate, inside the longjmp call.
+ (scm_ia64_longjmp): New function.
+
+ * __scm.h (setjmp, longjmp, jmp_buf): For IA64, implement using
+ getcontext and setcontext.
+
+2008-05-07 Ludovic Courtès <ludo@gnu.org>
+
+ * numbers.c (scm_from_complex_double): Mark as `SCM_UNUSED'.
+ This fixes compilation with `-Werror' on FreeBSD 6.2 (i386).
+
+2008-05-05 Neil Jerram <neil@ossau.uklinux.net>
+
+ * c-tokenize.lex: #define YY_NO_INPUT.
+
+2008-04-26 Ludovic Courtès <ludo@gnu.org>
+
+ * read.c (scm_read_sexp): Remove extraneous semi-colon at
+ end-of-line, which broke compilation with GCC 2.7. Reported by
+ Alain Guibert <alguibert+bts@free.fr>.
+
+2008-04-24 Ludovic Courtès <ludo@gnu.org>
+
+ * Makefile.am (DEFAULT_INCLUDES): New. Fixes compilation on
+ Tru64 where our "random.h" would shadown libc's one.
+ (INCLUDES): Add "-I$(top_buildir)", which is normally in
+ `DEFAULT_INCLUDES'.
+ * gen-scmconfig.c: Include <libguile/gen-scmconfig.h>, not
+ "gen-scmconfig.h" since that file is under `$(builddir)'.
+
+2008-04-16 Ludovic Courtès <ludo@gnu.org>
+
+ Copy Han-Wen's srcprop reimplementation from the 1.9 branch,
+ dated 2007-01-19. Fixes a deadlock with `scm_make_srcprops ()':
+ http://lists.gnu.org/archive/html/guile-devel/2008-03/msg00014.html .
+
+ * srcprop.c: use double cell for storing source-properties. Put
+ filename in the plist, and share between srcprops if possible.
+ Remove specialized storage.
+ * srcprop.h: remove macros without SCM_ prefix from
+ interface. Remove specialized storage/type definitions.
+
+2008-04-16 Ludovic Courtès <ludo@gnu.org>
+
+ * ports.c (scm_getc, scm_putc, scm_puts): Moved...
+ * inline.h: ... here. Noticeably improves `read' performance.
+
+2008-04-15 Ludovic Courtès <ludo@gnu.org>
+ Julian Graham <joolean@gmail.com>
+
+ * read.c (scm_keyword_postfix): New.
+ (scm_read_opts): Update docstring for `keywords'.
+ (scm_read_mixed_case_symbol): Add support for postfix keywords.
+
+2008-04-13 Ludovic Courtès <ludo@gnu.org>
+
+ * inline.h (SCM_C_USE_EXTERN_INLINE): New macro. Use it to make
+ sure "extern" declarations are produced when "extern inline" is
+ used. Simplify macrology around inline definitions.
+
+2008-04-10 Ludovic Courtès <ludo@gnu.org>
+
+ * inline.h (SCM_C_EXTERN_INLINE): Special-case Apple's GCC
+ 4.0-based compiler, which doesn't support GNU inline semantics
+ at all in C99 mode but doesn't define `__GNUC_STDC_INLINE__'.
+ See http://thread.gmane.org/gmane.network.gnutls.general/1135 .
+
+2008-04-10 Andy Wingo <wingo@pobox.com>
+
+ * struct.c (scm_struct_ref, scm_struct_set_x): "Light" structs
+ have no hidden words (members of the SCM_STRUCT_DATA(x) array
+ accessed with negative indices). In that case, determine the
+ number of fields from the length of the struct layout
+ descriptor. (Most GOOPS instances are light structs.)
+
+ * goops.c (wrap_init): Initialize 'u' slots to 0, not some random
+ SCM value.
+
+ * goops.c (get_slot_value, set_slot_value): In the struct
+ allocation case, don't poke the slots array directly -- we should
+ go through struct-ref/struct-set! code so that we get the
+ permissions and allocation ('u' versus 'p') correct.
+
+2008-04-03 Ludovic Courtès <ludo@gnu.org>
+
+ * inline.h (SCM_C_EXTERN_INLINE): New macro, addresses the
+ "extern inline" semantic change in C99 mode with GCC 4.3 and
+ later and the warning in C99 mode with GCC 4.2. Use it in the
+ inline function definitions.
+
+2008-03-10 Ludovic Courtès <ludo@gnu.org>
+
+ * eval.c, filesys.c: Enclose `alloca' blob in `#ifndef alloca',
+ as per Gnulib's `alloca'. This should fix compilation on
+ FreeBSD 6.
+
+2008-03-09 Neil Jerram <neil@ossau.uklinux.net>
+
+ * numbers.c: Only define scm_from_complex_double if it will
+ actually be used.
+
+2008-03-06 Ludovic Courtès <ludo@gnu.org>
+
+ * eval.c (scm_eval): If MODULE_OR_STATE is not a dynamic state,
+ make sure it's a module. Reported by David I. Lehn.
+
+2008-03-02 Ludovic Courtès <ludo@gnu.org>
+
+ * pairs.h (scm_is_pair): Moved declaration to `inline.h'.
+ * inline.h: Make sure `extern' declarations are not produced
+ when `inline' is supported but GCC is not used. This
+ fixes "mixed linkage" errors with compilers such as
+ DEC/Compaq/HP CC.
+
+2008-02-27 Neil Jerram <neil@ossau.uklinux.net>
+
+ * _scm.h (errno): Remove declarations that have been there
+ forever, and are known to conflict on some platforms with that
+ provided by <errno.h>, which we include unconditionally. If
+ <errno.h> doesn't provide a errno declaration, what is the point
+ of it?
+
+2008-02-23 Ludovic Courtès <ludo@gnu.org>
+
+ * numbers.c (scm_make_rectangular): Rename argument to
+ `real_part' and `imaginary_part' to work around Solaris 2.10
+ headers which define `imaginary' as a macro. Patch by Tim
+ Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>.
+
+2008-02-22 Ludovic Courtès <ludo@gnu.org>
+
+ * read.c (strncasecmp): Add declaration when
+ `HAVE_DECL_STRNCASECMP' is undefined. Fixes compilation on
+ NetBSD 1.6.
+
+ * gc.c (scm_ia64_ar_bsp)[linux]: Don't discard `const' qualifier
+ of OPAQUE.
+
+2008-02-21 Ludovic Courtès <ludo@gnu.org>
+
+ Fix bug #22369.
+
+ * goops.c (scm_add_slot): Add `SCM_UNDEFINED' as last argument
+ to `scm_list_n ()'. Thanks to René Köcher
+ <shirk87@googlemail.com>.
+
+2008-02-17 Ludovic Courtès <ludo@gnu.org>
+
+ * script.c (scm_compile_shell_switches): Update copyright year.
+
+2008-02-16 Ludovic Courtès <ludo@gnu.org>
+
+ * gc_os_dep.c: Add NetBSD/alpha support. Patch by Greg Troxel
+ <gdt@ir.bbn.com>.
+
+2008-02-12 Ludovic Courtès <ludo@gnu.org>
+
+ * guile-snarf.in (tempdir): Honor `$TMPDIR'.
+
+2008-02-11 Neil Jerram <neil@ossau.uklinux.net>
+
+ * numbers.c (SCM_COMPLEX_VALUE): Use GUILE_I instead of _Complex_I
+ directly, and only if GUILE_I was defined by the configure step.
+ (scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
+ code only if SCM_COMPLEX_VALUE is defined.
+
+2008-02-07 Ludovic Courtès <ludo@gnu.org>
+
+ Fix bug #21378.
+ Thanks to David Diffenbaugh <davediff@nbcs.rutgers.edu>.
+
+ * read.c (scm_read_quote): Don't use `__FUNCTION__' since it is
+ not supported by Sun CC on Solaris 9.
+ (scm_read_keyword): Likewise.
+ * strings.c (scm_take_locale_stringn): Remove
+ `SCM_C_INLINE_KEYWORD' to allow compilation with Sun CC.
+
+2008-02-07 Julian Graham <joolean@gmail.com>
+
+ * throw.c (make_jmpbuf): Don't enter critical section during thread
+ spawn -- there is a possibility of deadlock if other threads are
+ exiting.
+
+2008-02-06 Neil Jerram <neil@ossau.uklinux.net>
+
+ * gc-malloc.c (scm_gc_malloc): Return NULL if requested size is 0.
+ (scm_gc_free): Don't call `free' if mem is NULL.
+
+2008-02-06 Ludovic Courtès <ludo@gnu.org>
+
+ * numbers.c (scm_i_mkbig, scm_i_long2big, scm_i_ulong2big,
+ scm_i_clonebig, scm_i_bigcmp, scm_i_dbl2big, scm_i_dbl2num,
+ scm_i_normbig): Remove `SCM_C_INLINE_KEYWORD' since these are
+ declared as `extern' in `numbers.h'. This precluded compilation
+ on Solaris 9 with Sun CC (reported by David Halik
+ <dhalik@nbcs.rutgers.edu>).
+
+2008-02-05 Neil Jerram <neil@ossau.uklinux.net>
+
+ * fports.c (fport_seek): Make dependent on GUILE_USE_64_CALLS.
+
+ * _scm.h: Make definition of CHOOSE_LARGEFILE depend on
+ GUILE_USE_64_CALLS.
+
+2008-02-01 Neil Jerram <neil@ossau.uklinux.net>
+
+ * modules.c (the_root_module): Moved before scm_current_module.
+ (scm_current_module): Return the root module if `the-module' fluid
+ gives #f.
+
+2008-01-22 Neil Jerram <neil@ossau.uklinux.net>
+
+ * COPYING: Removed.
+
+ * __scm.h, _scm.h, weaks.c: Update copyright statement to LGPL.
+
+2008-01-18 Neil Jerram <neil@ossau.uklinux.net>
+
+ * hashtab.c (scm_hash_fn_create_handle_x): If supplied assoc_fn
+ returns neither a pair nor #f, signal a wrong-type-arg error.
+ (Thanks to Gregory Marton for reporting this.)
+
+2007-12-29 Neil Jerram <neil@ossau.uklinux.net>
+
+ * gc.c (mark_gc_async): Change "func_data" to "fn_data", to avoid
+ clash with AIX header file.
+ * hooks.c (scm_c_hook_add, scm_c_hook_remove): Same again.
+ * hooks.h (scm_t_c_hook_function, scm_c_hook_add,
+ scm_c_hook_remove): Same again.
+
+2007-12-08 Ludovic Courtès <ludo@gnu.org>
+
+ * __scm.h (SCM_EXPECT, SCM_LIKELY, SCM_UNLIKELY): New macros.
+ (SCM_ASSERT, SCM_ASSERT_TYPE, SCM_ASRTGO, SCM_GASSERT0,
+ SCM_GASSERT1, SCM_GASSERT2, SCM_GASSERTn): Use them.
+ * eval.c (ASSERT_SYNTAX, ASSERT_SYNTAX_2): Likewise.
+ (CEVAL): Use branch prediction hints for syntax errors, wrong
+ number of arguments and similar.
+ * numbers.c (scm_sum): Use `SCM_LIKELY' for the sum of two
+ immediate numbers.
+ (scm_difference, scm_product, scm_i_divide): Likewise.
+ * validate.h (SCM_ASSERT_RANGE): Use `SCM_UNLIKELY'.
+
+2007-12-04 Ludovic Courtès <ludo@gnu.org>
+
+ * ports.c (scm_c_read): Validate PORT as an open input port.
+ (scm_c_write): Validate PORT as an open output port.
+
+ * socket.c (scm_accept): Leave guile mode using
+ `scm_std_select ()' before calling `accept(2)'. Reported by
+ dskr <dskr@mac.com>.
+
+2007-10-19 Neil Jerram <neil@ossau.uklinux.net>
+
+ * eval.c (unmemoize_delay): Extend the environment before
+ unmemoizing the promise thunk. This fixes a segmentation fault
+ reported by Frank Schwidom.
+
+2007-10-17 Ludovic Courtès <ludo@gnu.org>
+
+ * read.c (CHAR_IS_BLANK_): Add `\r' (ASCII 0x0d). This fixes a
+ regression compared to 1.8.2. Reported by Puneet
+ <schemer@gmail.com>.
+
+2007-10-10 Ludovic Courtès <ludo@gnu.org>
+
+ * pthread-threads.h (SCM_I_PTHREAD_MUTEX_INITIALIZER): Check
+ `SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
+ * gen-scmconfig.h.in
+ (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER): New.
+ * gen-scmconfig.c (main): Define
+ `SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
+
+2007-10-02 Ludovic Courtès <ludo@gnu.org>
+
+ * threads.c (on_thread_exit): Don't call `scm_leave_guile ()'
+ since we're already in non-guile mode. Reported by Greg Toxel
+ for NetBSD.
+
+2007-09-11 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_putenv): Confine the putenv("NAME=") bit to mingw, use
+ putenv("NAME") as the fallback everywhere else. In particular this is
+ needed for solaris 9. Reported by Frank Storbeck.
+
+2007-09-03 Ludovic Courtès <ludo@gnu.org>
+
+ * read.c (flush_ws): Handle SCSH block comments.
+
+2007-09-03 Ludovic Courtès <ludo@gnu.org>
+
+ Fix alignment issues which showed up at least on SPARC.
+
+ * socket.c (scm_t_max_sockaddr, scm_t_getsockopt_result): New.
+ (scm_inet_pton): Change DST to `scm_t_uint32' for correct
+ alignment.
+ (scm_getsockopt): Change OPTVAL to `scm_t_getsockopt_result' for
+ correct alignment.
+ (_scm_from_sockaddr): Change ADDRESS to `scm_t_max_sockaddr *'.
+ (scm_from_sockaddr): Cast ADDRESS to `scm_t_max_sockaddr *'.
+ (MAX_SIZE_UN, MAX_SIZE_IN6): Removed.
+ (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
+ Use `scm_t_max_sockaddr' instead of "char max_addr[MAX_ADDR_SIZE]".
+
+2007-09-03 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE
+ before using clog(). It's possible for gcc to provide the "complex
+ double" type, but for the system not to have the complex funcs.
+ (scm_exp): Ditto HAVE_CEXP for cexp().
+
+2007-09-02 Ludovic Courtès <ludo@gnu.org>
+
+ * socket.c (scm_make_socket_address): Free C_ADDRESS after use.
+ This fixes a memory leak.
+
+2007-08-23 Ludovic Courtès <ludo@gnu.org>
+
+ * read.c (scm_read_quote): Record position and copy source
+ expression when asked to. Reported by Kevin.
+
+ * stime.c: Define `_REENTRANT' only if not already defined.
+
+2007-08-21 Kevin Ryde <user42@zip.com.au>
+
+ * gc-card.c (scm_i_card_statistics): Record scm_tc7_number types as
+ tc16 values so big, real, complex and fraction can be distinguished.
+
+ (scm_i_tag_name): Return "number" for scm_tc7_number, not NULL. NULL
+ was making numbers come out as "type 23" in gc-live-object-stats.
+ Fix tests of the tc16 number types, they were checked under
+ scm_tc7_number, but the values went down the tag>=255 smob case.
+ Put smob case under scm_tc7_smob instead of using tag>=255, per
+ recommendation in comments with scm_tc7_smob to use symbolic values.
+ Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
+ code. Lose some unnecessary "break" statements.
+
+ (scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
+ element returned, rather than two lookups scm_hashq_ref and
+ scm_hashq_set_x.
+
+2007-08-17 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c: Add #define _REENTRANT, to get gmtime_r() prototype on
+ solaris 2.6. Reported by anirkko.
+
+2007-08-11 Ludovic Courtès <ludo@gnu.org>
+
+ Overhauled the reader, making it faster.
+
+ * gdbint.c (tok_buf, tok_buf_mark_p): Removed.
+ (gdb_read): Don't use a token buffer. Use `scm_read ()' instead
+ of `scm_lreadr ()'.
+
+ * read.c: Overhauled. No longer use a token buffer. Use a
+ on-stack C buffer in the common case and use Scheme strings when
+ larger buffers are needed.
+ * read.h (scm_grow_tok_buf, scm_flush_ws, scm_casei_streq,
+ scm_lreadr, scm_lreadrecparen): Removed.
+ (scm_i_input_error): Marked as `SCM_NORETURN'.
+
+2007-07-25 Ludovic Courtès <ludo@gnu.org>
+
+ * eval.c (macroexp): When `scm_ilength (res) <= 0', return
+ immediately. This used to produce a circular memoized
+ expression, e.g., for `(set (quote x) #t)'.
+
+2007-07-15 Ludovic Courtès <ludo@gnu.org>
+
+ * script.c (scm_compile_shell_switches): Updated copyright year.
+
+2007-07-11 Ludovic Courtès <ludo@gnu.org>
+
+ * goops.c (scm_sys_method_more_specific_p): Added docstring.
+ Make sure LEN is greater than or equal to the minimum length of
+ specializers of M1 and M2. This fixes a segfault later on in
+ `more_specificp ()' if TARGS is too small. Reported by Marco
+ Maggi <marco.maggi-ipsu@poste.it>.
+
+2007-06-26 Ludovic Courtès <ludo@gnu.org>
+
+ * fluids.c (next_fluid_num): When growing ALLOCATED_FLUIDS, make
+ sure to free the previous array after the new one has been
+ installed. This leak is made visible by running
+ "(define l (map (lambda (i) (make-fluid)) (iota 255)))"
+ from the REPL within Valgrind.
+
+2007-06-13 Ludovic Courtès <ludo@chbouib.org>
+
+ * eval.c (scm_m_define): Updated comment. Changed order for value
+ evaluation and `scm_sym2var ()' call, which is perfectly valid per
+ R5RS. This reverts the change dated 2004-04-22 by Dirk Herrmann.
+
+2007-06-12 Ludovic Courtès <ludo@chbouib.org>
+
+ * socket.c (scm_inet_ntop): In the `AF_INET' case, declare `addr4'
+ as an `scm_t_uint32' rather than re-using `addr6'. This fixes a
+ bus error on SPARC (and possibly others) due to unaligned access.
+
+2007-06-07 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * posix.c (scm_ttyname): Check whether RESULT is NULL before
+ making a string from it (reported by Dan McMahill). Don't call
+ `scm_from_locale_string ()' before the mutex is released.
+
+2007-03-08 Kevin Ryde <user42@zip.com.au>
+
+ * struct.c, struct.h (scm_make_vtable): New function, providing
+ `make-vtable'.
+ * stacks.c (scm_init_stacks): Use it.
+
+2007-03-06 Kevin Ryde <user42@zip.com.au>
+
+ * struct.c (scm_make_struct): Check for R,W,O at end of layout when
+ allocating a tail array. If there's no such then those tail fields
+ are uninitialized and garbage SCMs there can cause a segv if printed
+ (after fetching with struct-ref).
+
+2007-02-22 Kevin Ryde <user42@zip.com.au>
+
+ * scmsigs.c (scm_sleep): In docstring, cross refence usleep.
+ (scm_usleep): Update docstring per manual, cross reference sleep.
+
+ * struct.c (scm_make_struct): Move SCM_CRITICAL_SECTION_END up so that
+ scm_struct_init is not within that section. scm_struct_init can
+ thrown an error, which within a critical section results in an
+ abort().
+
+2007-01-28 Neil Jerram <neil@ossau.uklinux.net>
+
+ IA64 HP-UX GC patch from Hrvoje Nikšić. (Thanks!)
+
+ * threads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp() and
+ scm_ia64_register_backing_store_base() instead of Linux-specific
+ implementations.
+
+ * gc.h (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp):
+ New declarations.
+
+ * gc.c (__libc_ia64_register_backing_store_base): Declaration
+ removed.
+ (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp): New, with
+ implementations for Linux and HP-UX.
+
+ * coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
+ and scm_ia64_register_backing_store_base() instead of
+ Linux-specific implementations.
+
+ * continuations.h (__libc_ia64_register_backing_store_base):
+ Declaration removed.
+ (scm_t_contregs): New "fresh" field.
+
+ * continuations.c (ia64_getcontext): Removed.
+ (scm_make_continuation): Use continuation fresh field instead of
+ interpreting getcontext return values (which isn't portable). Use
+ scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
+ instead of Linux-specific implementations.
+ (copy_stack_and_call): Use scm_ia64_register_backing_store_base()
+ instead of Linux-specific implementation.
+
+ * _scm.h (__ia64__): Also detect __ia64.
+
+2007-01-27 Kevin Ryde <user42@zip.com.au>
+
+ * ports.c (scm_port_line, scm_set_port_line_x), read.c
+ (scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
+ port line number type, should be "long" not "int", as per line_number
+ field of scm_t_port. (Makes a difference only on 64-bit systems, and
+ only then for a linenum above 2Gig.)
+
+2007-01-25 Kevin Ryde <user42@zip.com.au>
+
+ * sort.c (scm_stable_sort): Return empty list for input empty list, as
+ done in guile 1.6 and as always done by plain `sort'. Was falling
+ through to SCM_WRONG_TYPE_ARG. Reported by Ales Hvezda.
+
+2007-01-23 Han-Wen Nienhuys <hanwen@lilypond.org>
+
+ * gc.c (s_scm_gc_stats): return total cells allocated in a run as
+ 'total-cells-allocated in gc-stats output. This allows profiling
+ of a program's memory use.
+
+ * gc-segment.c (scm_i_sweep_some_cards): update
+ scm_gc_cells_allocated_acc when sweeping happens.
+
+ * gc.h: add scm_gc_cells_allocated_acc, scm_last_cells_allocated.
+
+
+2007-01-19 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * struct.c (scm_i_struct_equalp): Skip comparison if both FIELD1
+ is equal to S1 and FIELD2 is equal to S2. This avoids infinite
+ recursion when comparing `s' fields, as the REQUIRED_VTABLE_FIELDS
+ added by `make-vtable-vtable'. Reported by Marco Maggi.
+
+2007-01-16 Kevin Ryde <user42@zip.com.au>
+
+ * feature.c, feature.h (scm_set_program_arguments_scm): New function,
+ implementing `set-program-arguments'.
+
+ * filesys.c (scm_init_filesys): Use scm_from_int rather than
+ scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
+ O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
+ O_LARGEFILE. These are all int not long, per arg to open().
+ (scm_init_filesys): Use scm_from_int rather than scm_from_long for
+ F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
+ are all ints (per command arg to fcntl). Likewise FD_CLOEXEC which is
+ an int arg to fcntl.
+
+ * posix.c (scm_putenv): Correction to "len" variable, was defined only
+ for __MINGW32__ but used under any !HAVE_UNSETENV (such as solaris).
+ Move it to where it's used. Reported by Hugh Sasse.
+
+ * regex-posix.c (scm_regexp_exec): Remove SCM_CRITICAL_SECTION_START
+ and SCM_CRITICAL_SECTION_END, believe not needed. Their placement
+ meant #\nul in the input (detected by scm_to_locale_string) and a bad
+ flags arg (detected by scm_to_int) would throw from a critical
+ section, causing an abort().
+
+ * regex-posix.c (scm_init_regex_posix): Use scm_from_int for
+ REG_BASIC, REG_EXTENDED, REG_ICASE, REG_NEWLINE, REG_NOTBOL,
+ REG_NOTEOL; they're all ints not longs (per args to regcomp and
+ regexec).
+
+2007-01-04 Kevin Ryde <user42@zip.com.au>
+
+ * deprecated.h (scm_create_hook), version.h.in (scm_major_version,
+ scm_minor_version, scm_micro_version, scm_effective_version,
+ scm_version, scm_init_version): Use SCM_API instead of just extern,
+ for the benefit of mingw. Reported by Cesar Strauss.
+
+2006-12-27 Kevin Ryde <user42@zip.com.au>
+
+ * threads.c (get_thread_stack_base): In mingw with pthreads we can use
+ the basic scm_get_stack_base. As advised by Nils Durner.
+
+ * threads.c (get_thread_stack_base): Add a version using
+ pthread_get_stackaddr_np (when available), for the benefit of MacOS.
+ As advised by Heikki Lindholm.
+
+ * scmsigs.c (signal_delivery_thread): Restrict scm_i_pthread_sigmask
+ to HAVE_PTHREAD_SIGMASK, it doesn't exist on mingw. Reported by Nils
+ Durner.
+
+2006-12-24 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_kill): When only raise() is available, throw an ENOSYS
+ error if pid is not our own process, instead of silently doing nothing.
+
+ * print.c (scm_write, scm_display, scm_write_char): Disable port close
+ on EPIPE. This was previously disabled but introduction of HAVE_PIPE
+ check in configure.in unintentionally enabled it. Believe that
+ testing errno after scm_prin1 or scm_putc is bogus, a long ago error
+ can leave errno in that state. popen.test "no duplicates" output test
+ provoked that.
+
+2006-12-23 Han-Wen Nienhuys <hanwen@lilypond.org>
+
+ * numbers.c (scm_i_fraction_reduce): move logic into
+ scm_i_make_ratio(), so fractions are only read.
+ scm_i_fraction_reduce() modifies a fraction when reading it. A
+ race condition might lead to fractions being corrupted by reading
+ them concurrently.
+
+ Also, the REDUCED bit alters the SCM_CELL_TYPE(), making
+ comparisons between reduced and unreduced fractions go wrong.
+
+ * numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
+ SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
+ SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
+ SCM_FRACTION_REDUCED.
+
+2006-12-16 Kevin Ryde <user42@zip.com.au>
+
+ * scmsigs.c (scm_raise): Use raise() rather than kill(), as this is
+ more direct for a procedure called raise.
+ (kill): Remove mingw fake fallback.
+
+2006-12-15 Kevin Ryde <user42@zip.com.au>
+
+ * scmsigs.c: Conditionalize process.h, add io.h believe needed for
+ _pipe on mingw.
+
+2006-12-14 Kevin Ryde <user42@zip.com.au>
+
+ * threads.c (thread_print): Cope with the case where pthread_t is a
+ struct, as found on mingw. Can't just cast to size_t for printing.
+ Reported by Nils Durner.
+
+ * scmsigs.c: Add <fcntl.h> and <process.h> needed by mingw. Copy the
+ fallback pipe() using _pipe() from posix.c. Reported by Nils Durner.
+
+2006-12-13 Kevin Ryde <user42@zip.com.au>
+
+ * eval.c (scm_m_define): Set 'name procedure property on any
+ scm_procedure_p, not just SCM_CLOSUREP. In particular this picks up
+ procedures with setters as used in srfi-17.
+
+ * posix.c (scm_crypt): Check for NULL return from crypt(), which the
+ linux man page says is a possibility.
+
+2006-12-12 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * libguile/unif.c (read_decimal_integer): Let RESP be SIGN * RES
+ instead of RES (reported by Szavai Gyula). This allows the use of
+ negative lower bounds.
+ (scm_i_read_array): Make sure LEN is non-negative (reported by
+ Szavai Gyula).
+
+ (scm_array_in_bounds_p): Iterate over S instead of always
+ comparing indices with the bounds of S[0]. This fixes
+ `array-in-bounds?' for arrays with a rank greater than one and
+ with different lower bounds for each dimension.
+
+2006-12-05 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_product): For flonum*inum and complex*inum, return
+ exact 0 if inum==0. Already done for inum*flonum and inum*complex,
+ and as per R5RS section "Exactness".
+
+2006-12-03 Kevin Ryde <user42@zip.com.au>
+
+ * Makefile.am (.c.doc): Remove the "test -n" apparently attempting to
+ allow $AWK from the environment to override. It had syntax gremlins,
+ and the presence of a $(AWK) variable set by AC_PROG_AWK in the
+ Makefile stopped it having any effect. Use just $(AWK), which can be
+ overridden with "make AWK=xxx" in the usual way if desired.
+
+2006-11-29 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * libguile/vectors.c (scm_vector_to_list): Fixed list
+ construction: elements were not copied when INC is zero (see
+ "shared array" example in `vectors.test'). Reported by
+ Szavai Gyula.
+
+2006-10-03 Kevin Ryde <user42@zip.com.au>
+
+ * eval.c (SCM_APPLY): For scm_tc7_subr_2o, throw wrong-num-args on 0
+ arguments or 3 or more arguments. Previously 0 called proc with
+ SCM_UNDEFINED, and 3 or more silently used just the first 2.
+
+2006-09-28 Kevin Ryde <user42@zip.com.au>
+
+ * fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
+ for chsize fallback, instead of hard-coding mingw. Mingw in fact
+ supplies ftruncate itself these days.
+
+ * ports.c (fcntl.h): Can include this unconditionally, no need for
+ __MINGW32__.
+
+ * ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
+ HAVE_TRUNCATE" so as not to hard-code mingw. Use "const char *" and
+ "off_t" for parameters, per usual definition of this function, rather
+ than "char *" and "int". Use ftruncate instead of chsize. Check for
+ error on final close.
+
+2006-09-27 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
+ in mingw.
+
+ * posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
+ const *" for mingw to suppress warnings from gcc (which are errors
+ under the configure default -Werror). Reported by Nils Durner.
+
+2006-09-26 Kevin Ryde <user42@zip.com.au>
+
+ * _scm.h (scm_to_off64_t, scm_from_off64_t): New macros.
+ * fports.c (scm_open_file): Use open_or_open64.
+ (fport_seek_or_seek64): New function, adapting fport_seek.
+ * fports.c, fports.h (scm_i_fport_seek, scm_i_fport_truncate): New
+ functions.
+ * ports.c (scm_seek, scm_truncate_file): Use scm_i_fport_seek and
+ scm_i_fport_truncate to allow 64-bit seeks and truncates on fports.
+
+ * ports.c (scm_truncate_file): Update docstring per manual.
+
+2006-09-23 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c, numbers.h (scm_log, scm_log10, scm_exp, scm_sqrt): New
+ functions.
+
+2006-09-20 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * srfi-14.c: Include <config.h>. Define `_GNU_SOURCE'.
+ (make_predset, define_predset, make_strset, define_strset, false,
+ true): Removed.
+ (SCM_CHARSET_UNSET, CSET_BLANK_PRED, CSET_SYMBOL_PRED,
+ CSET_PUNCT_PRED, CSET_LOWER_PRED, CSET_UPPER_PRED,
+ CSET_LETTER_PRED, CSET_DIGIT_PRED, CSET_WHITESPACE_PRED,

+ CSET_LETTER_AND_DIGIT_PRED, CSET_GRAPHIC_PRED, CSET_PRINTING_PRED,
+ CSET_TRUE_PRED, CSET_FALSE_PRED, UPDATE_CSET): New macros.
+ (define_charset, scm_srfi_14_compute_char_sets): New functions.
+ (scm_init_srfi_14): Use `define_charset ()' instead of
+ `define_predset ()' and `define_strset ()'.
+
+ * srfi-14.h (scm_c_init_srfi_14): Removed.
+ (scm_srfi_14_compute_char_sets): New declaration.
+
+ * posix.h: Include "srfi-14.h".
+ (scm_setlocale): Invoke `scm_srfi_14_compute_char_sets ()' after a
+ successful `setlocale ()' call.
+
+2006-09-08 Kevin Ryde <user42@zip.com.au>
+
+ * socket.c (scm_init_socket): Add MSG_DONTWAIT.
+ (scm_recvfrom): Update docstring from manual.
+
+2006-08-31 Rob Browning <rlb@defaultvalue.org>
+
+ * ports.c (scm_c_port_for_each): Add a
+ scm_remember_upto_here_1(ports) at the end of the function to fix
+ a GC bug.
+
+2006-08-12 Kevin Ryde <user42@zip.com.au>
+
+ * gen-scmconfig.h.in (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_ONCE_INIT):
+ New, set from configure.
+ * gen-scmconfig.c (SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT): New output
+ to scmconfig.h.
+ * pthread-threads.h (SCM_I_PTHREAD_ONCE_INIT): Use
+ SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT to cope with Solaris.
+ Reported by Claes Wallin.
+
+2006-07-25 Kevin Ryde <user42@zip.com.au>
+
+ * threads.c (get_thread_stack_base): Restrict HAVE_PTHREAD_GETATTR_NP
+ on pthreads version, since pthread_getattr_np not available on solaris
+ and macos. Reported by Claes Wallin.
+
+2006-07-24 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (dirfd): Test with #ifndef rather than HAVE_DIRFD, since
+ it's a macro on MacOS X. Reported by Claes Wallin.
+
+ * posix.c (sethostname): Give prototype if not HAVE_DECL_SETHOSTNAME,
+ for the benefit of Solaris 10. Reported by Claes Wallin.
+
+ * socket.c (scm_htonl, scm_ntohl): Use scm_to_uint32 rather than
+ NUM2ULONG, to enforce 32-bit range check on systems with 64-bit long.
+
+2006-07-21 Kevin Ryde <user42@zip.com.au>
+
+ * eval.c, filesys.c (alloca): Update <alloca.h> etc blob, per current
+ autoconf recommendation. Should fix Solaris 10 reported by Claes
+ Wallin.
+
+ * threads.c: Include <string.h>, needed for memset() which is used by
+ FD_ZERO() on Solaris 10. Reported by Claes Wallin.
+
+2006-07-18 Rob Browning <rlb@defaultvalue.org>
+
+ * continuations.c: Add __attribute__ ((returns_twice)) to the
+ ia64_getcontext prototype so that gcc will make the right
+ arrangements and avoid an illegal instruction during
+ call-with-current-continuation.
+
+2006-07-12 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * numbers.c (guile_ieee_init): Use regular ANSI C casts rather
+ than C++-style `X_CAST ()'. Patch posted by by Mike Gran.
+
+2006-07-08 Kevin Ryde <user42@zip.com.au>
+
+ * environments.c (core_environments_unobserve): Use if/else rather
+ than ?: for "SET" bits, avoiding complaints from AIX xlc compiler
+ about them not being rvalues. Reported by Mike Gran.
+
+ * Makefile.am (version.h): Don't use $< in an explicit rule, it's not
+ portable and in particular fails on OpenBSD and AIX (see autoconf
+ manual too). Reported by Mike Gran.
+
+2006-06-25 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c (bdtime2c): tm_gmtoff is seconds East, so take negative of
+ tm:gmtoff which is seconds West. Reported by Aaron VanDevender.
+ (bdtime2c): Test HAVE_STRUCT_TM_TM_GMTOFF for tm_gmtoff, rather than
+ HAVE_TM_ZONE.
+ (scm_strptime): Use tm_gmtoff from the strptime result when that field
+ exists, it's set by glibc strptime "%s".
+
+2006-06-13 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * eq.c: Include "struct.h", "goops.h" and "objects.h".
+ (scm_equal_p): Invoke `scm_i_struct_equalp ()' on structures that
+ are not GOOPS instances.
+ * struct.c: Include "eq.h".
+ (scm_free_structs): Use `SCM_STRUCT_VTABLE_DATA ()' instead of
+ hand-written code.
+ (scm_i_struct_equalp): New.
+ * struct.h (scm_i_struct_equalp): New declaration.
+
+2006-06-06 Kevin Ryde <user42@zip.com.au>
+
+ * Makefile.am (BUILT_SOURCES): Remove guile.texi, only used by

+ reported by Mattias Holm.
+
+2006-06-03 Kevin Ryde <user42@zip.com.au>
+
+ * read.c (s_vector): Conditionalize on SCM_ENABLE_ELISP, to avoid
+ unused variable warning when elisp disabled. Reported by Ryan
+ VanderBijl.
+
+ * throw.c (scm_handle_by_message): Add dummy return value to avoid
+ compiler warning on cygwin. Reported by Ryan VanderBijl.
+
+ * Makefile.am (EXTRA_DOT_X_FILES): Typo in dependency rule, was a
+ duplicate of EXTRA_DOT_DOC_FILES.
+ (DOT_X_FILES, EXTRA_DOT_X_FILES, DOT_DOC_FILES, EXTRA_DOT_DOC_FILES):
+ Add scmconfig.h to dependencies, since these all run cpp. Helps a
+ parallel "make -j2". Reported by Mattias Holm.
+
+2006-05-30 Kevin Ryde <user42@zip.com.au>
+
+ * ports.c, ports.h (scm_set_port_mark, scm_set_port_free,
+ scm_set_port_print, scm_set_port_equalp, scm_set_port_flush,
+ scm_set_port_end_input, scm_set_port_close, scm_set_port_seek,
+ scm_set_port_truncate, scm_set_port_input_waiting): Use scm_t_bits for
+ port type descriptor, same as scm_make_port_type return value.
+
+2006-05-30 Marius Vollmer <mvo@zagadka.de>
+
+ * eq.c (scm_equal_p): Use scm_array_equal_p explicitely when one
+ of the arguments is a array. This allows vectors to be equal to
+ one-dimensional arrays.
+
+2006-05-29 Marius Vollmer <mvo@zagadka.de>
+
+ * throw.c (scm_ithrow): When looking for the jmpbuf, first test
+ that we have a pair before accessing its cdr. Thanks to Bill
+ Schottstaedt!
+
+2006-05-28 Kevin Ryde <user42@zip.com.au>
+
+ * eval.c, filesys.c: Add malloc.h to get alloca() on mingw. Reported
+ by "The Senator".
+
+2006-05-27 Marius Vollmer <mvo@zagadka.de>
+
+ * srfi-4.c, strings.c: Replace SCM_C_INLINE with
+ SCM_C_INLINE_KEYWORD. Thanks to Mark Gran!
+
+2006-05-26 Kevin Ryde <user42@zip.com.au>
+
+ * fports.c (fport_input_waiting): For ioctl, check HAVE_IOCTL as well
+ as defined(FIONREAD), since mingw has FIONREAD but not ioctl().
+ Reported by "The Senator".
+ For select and ioctl, move fdes into those conditionals, to avoid
+ unused variable warning when neither of those used.
+
+2006-05-23 Kevin Ryde <user42@zip.com.au>
+
+ * fports.c: Remove "fwrite" declaration under "! HAVE_UNISTD_H".
+ It's unused and will be in stdio.h anyway (if it's anywhere).
+
+2006-05-20 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_stat2scm): Test #ifdef S_ISLNK directly, rather than
+ HAVE_S_ISLNK from configure (it was only a #ifdef test anyway).
+
+ * posix.c (scm_mknod): Test #ifdef S_IFLNK before using that (for
+ symlink). Probably can't create symlinks with mknod anyway though.
+
+ * inline.h (scm_is_pair): Add a workaround for i386 gcc 2.95 bad code
+ generation.
+
+2006-05-15 Kevin Ryde <user42@zip.com.au>
+
+ * simpos.c, simpos.h (scm_primitive__exit): New function.
+ (scm_primitive_exit): Update docstring, no longer the best exit after
+ a fork.
+
+2006-05-09 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_i_divide): For big/big wanting inexact, use mpq_get_d
+ rather than converting to doubles, to avoid inf or nan when the inputs
+ are too big for a double but the quotient does fit. This affects
+ conversions exact->inexact of big fractions.
+
+ * filesys.c (scm_open_fdes): Use open64.
+ (scm_init_filesys): Add O_LARGEFILE.
+
+ * ports.c (scm_seek): Use lseek64.
+ (scm_truncate_file): Use ftruncate64.
+
+2006-05-08 Marius Vollmer <mvo@zagadka.de>
+
+ * private-gc.h (CELL_P): Also check that the potential pointer is
+ correctly aligned for a cell. Thanks to Miroslav Lichvar!
+
+2006-04-18 Rob Browning <rlb@defaultvalue.org>
+
+ * _scm.h: Add back error if the size of off_t is unknown. The bug
+ was actually in guile-readline's configuration.
+
+2006-04-18 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_mkstemp): Update docstring from the manual, in
+ particular file mode 0600 is not guaranteed.
+
+2006-04-17 Kevin Ryde <user42@zip.com.au>
+
+ * _scm.h (scm_to_off_t, scm_from_off_t): No error if unknown off_t
+ size, to help the guile-readline build where off_t is unused.
+
+2006-04-16 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_stat2scm, scm_stat, scm_lstat): Use stat or stat64.
+ (scm_readdir): Use readdir64.
+ (scm_copy_file): Use open64 and fstat64, to cope with >2Gb files.
+ * ports.c (scm_truncate_file): Use truncate64. Correction truncate
+ and ftruncate take off_t not size_t.
+ * _scm.h (stat_or_stat64 etc): Macros for selecting LFS64 when
+ available.
+
+2006-04-06 Kevin Ryde <user42@zip.com.au>
+
+ * fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
+ instead of toggling it. Reported by Ludovic Courtès.
+
+2006-03-26 Marius Vollmer <mvo@zagadka.de>
+
+ * threads.c (get_thread_stack_base): Use scm_get_stack_base
+ instead of accessing __libc_stack_end directly, and only do this
+ when pthread_attr_getstack is known not to work for the main
+ thread or when not using pthreads at all.
+
+ * gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
+ unknown instead of returning NULL.
+
+2006-03-21 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * numbers.c (scm_i_mem2number): Renamed to
+ scm_c_locale_stringn_to_number.
+ * numbers.c, print.c, read.c: Updated callers.
+ * numbers.h: Update function declaration.
+
+2006-03-11 Neil Jerram <neil@ossau.uklinux.net>
+
+ * unif.c (string_set): Don't return in a void function. (Reported
+ by Mike Gran.)
+
+ * srfi-4.c (scm_uniform_vector_read_x): Declare base as char*
+ rather than void*, so we can do pointer arithmetic on it.
+ (Reported by Mike Gran.)
+ (s_scm_uniform_vector_write): Ditto.
+
+2006-03-10 Neil Jerram <neil@ossau.uklinux.net>
+
+ * unif.c (scm_make_shared_array): Don't use SCM_I_ARRAY_BASE when

+
+ * threads.c (do_unlock): Renamed from "unlock", which is defined
+ in unistd.h on QNX. (Reported by Matt Kraai.)
+
+2006-03-04 Kevin Ryde <user42@zip.com.au>
+
+ * deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,

+ * eval.c, posix.c: Change comments from C++ to C style. Reported by
+ Mike Gran.
+
+2006-02-28 Kevin Ryde <user42@zip.com.au>
+
+ * unif.c (bitvector_set): Use h->writable_elements not h->elements.
+
+2006-02-26 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_readdir): Use fpathconf for the dirent size when
+ NAME_MAX is not available, which is so on Solaris 10. Report and help
+ by Bill Schottstaedt.
+
+ * srfi-13.c (MY_VALIDATE_SUBSTRING_SPEC_UCOPY): New macro.
+ (scm_string_compare, scm_string_compare_ci, scm_string_lt,
+ scm_string_gt, scm_string_le, scm_string_ge, scm_string_ci_lt,
+ scm_string_ci_gt, scm_string_ci_le, scm_string_ci_ge): In comparisons
+ use "unsigned char", not signed char. This ensures comparisons are
+ the same as `char<?' etc, and is also the same as guile 1.6 did.
+ Reported by Sven Hartrumpf.
+
+2006-02-19 Mikael Djurfeldt <mdj@neurologic.cc>
+
+ * random.c: Test for SCM_HAVE_T_UINT64 instead of

+ scm_t_int32.
+
+2006-02-14 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of
+ LEN. Without this, too much collectable memory gets unregistered,
+ which results in an underflow of SCM_MALLOCATED in
+ `decrease_mtrigger()'.
+
+ * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or
+ equal to SCM_MALLOCATED.
+
+2006-02-13 Marius Vollmer <mvo@zagadka.de>
+
+ * eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock

+ configured --without-threads.
+ (SCM_APPLY, CEVAL): Likewise. Thanks to Han-Wen Nienhuys!
+
+2006-02-12 Marius Vollmer <mvo@zagadka.de>
+
+ * unif.c (scm_dimensions_to_uniform_array): Use the prototype for
+ filling when the fill parameter is omitted, as documented, but
+ turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
+ can not store characters.
+
+2006-02-09 Neil Jerram <neil@ossau.uklinux.net>
+
+ * socket.c (scm_c_make_socket_address): Pass address_size pointer

+
+ * throw.h (scm_c_catch, scm_c_with_throw_handler,
+ scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New.
+
+ * throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New.
+ (struct pre_unwind_data): New, replaces struct lazy_catch.
+ (scm_c_catch): New, replaces scm_internal_catch as the primary
+ catch API for C code; adds pre-unwind handler support.
+ (scm_internal_catch): Now just a wrapper for scm_c_catch, for back
+ compatibility.
+ (tc16_pre_unwind_data, pre_unwind_data_print,
+ make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from
+ "lazy_catch" equivalents.
+ (scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch
+ as the primary C API for a "lazy" catch.
+ (scm_internal_lazy_catch): Now just a wrapper for
+ scm_c_with_throw_handler, for back compatibility.
+ (scm_catch_with_pre_unwind_handler): Renamed from scm_catch; adds
+ pre-unwind handler support.
+ (scm_catch): Now just a wrapper for
+ scm_catch_with_pre_unwind_handler, for back compatibility.
+ (scm_with_throw_handler): New.
+ (scm_lazy_catch): Update comment to say that the handler can
+ return, and what happens if it does.
+ (toggle_pre_unwind_running): New.
+ (scm_ithrow): When identifying the throw target, take running
+ flags into account. In general, change naming of things from
+ "lazy_catch" to "pre_unwind". When throwing to a throw handler,
+ don't unwind the dynamic context first. Add dynwind framing to
+ manage the running flag of a throw handler. If a lazy catch or
+ throw handler returns, rethrow the same exception again. Add
+ pre-unwind support to the normal catch case (SCM_JMPBUFP).
+
+ * root.c (scm_internal_cwdr): Add NULL args to
+ scm_i_with_continuation_barrier call.
+
+ * dynwind.c: Change comment mentioning lazy-catch to mention
+ pre-unwind data and throw handler also.
+
+ * continuations.h (scm_i_with_continuation_barrier): Add
+ pre-unwind handler args.
+
+ * continuations.c (scm_i_with_continuation_barrier): Add

+ (scm_handler): Remove scm_handle_by_message_noexit call.
+ (s_scm_with_continuation_barrier): Call
+ scm_i_with_continuation_barrier with scm_handle_by_message_noexit

+
+2006-02-03 Kevin Ryde <user42@zip.com.au>
+
+ * list.c, list.h (scm_list): Restore this function for use from C.
+ It's a complete no-op but in theory might used by someone.
+
+2006-01-30 Marius Vollmer <mvo@zagadka.de>
+
+ * eval.c (scm_eval_body): Lock source_mutex with a dynwind context
+ so that it gets unlocked in all cases.
+ (SCM_APPLY, CEVAL): Likewise.
+
+2006-01-29 Marius Vollmer <mvo@zagadka.de>
+
+ * ramap.c: (scm_array_map_x): Don't use scm_array_p, use
+ scm_is_typed_array instead.
+
+ Renamed the "frames" that are related to dynamic-wind to "dynamic
+ contexts. Renamed all functions from scm_frame_ to scm_dynwind_.
+ Updated documentation.
+
+ Disabled "futures":
+
+ * futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif".
+ * eval.c, init.c: Comment out all 'future' related things.
+
+2006-01-28 Marius Vollmer <mvo@zagadka.de>

+ * symbols.c (lookup_interned_symbol): New function.
+ (scm_i_c_mem2symbol): New function.
+ (scm_i_mem2symbol): Use `lookup_symbol ()'.
+ (scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'. This avoids

+
+ * load.c (the_reader, the_reader_fluid_num): New.
+ (scm_primitive_load): Support custom reader.
+ (scm_init_load): Init the_reader and the_reader_fluid_num; export
+ the_reader as `current-reader'.
+
+ * scmsigs.c (do_read_without_guile): Use the "raw_data" passed in
+ (rather than an uninitialized pointer on the stack).
+
+2005-12-07 Marius Vollmer <mvo@zagadka.de>
+
+ Reported by Bruce Korb:
+
+ * init.c (invoke_main_func): Don't call exit here. Throws that
+ are only caught by scm_with_guile will bypass us and would cause
+ scm_boot_guile to return erroneously.
+ (scm_boot_guile): Expect scm_with_guile to return and call exit
+ here, passing it an appropriate exit code.
+
+ From Andy Wingo:
+
+ * script.c (scm_find_executable): Compile fix -- fgetc returns an
+ unsigned char cast to an int, or -1 for EOS.
+
+2005-12-06 Marius Vollmer <mvo@zagadka.de>
+
+ * srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer

+
+ From Stephen Compall:
+
+ * eval.c (scm_m_cond): Recognize SRFI 61 cond syntax.
+ (CEVAL): Evaluate SRFI 61 cond clauses.
+
+2005-12-06 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL.
+ This was typically hit when running `gc-live-object-stats' right

+
+2005-11-30 Kevin Ryde <user42@zip.com.au>
+
+ * srfi-13.c (scm_string_append_shared): No copying if just one

+
+ * random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for
+ scm_malloc returning NULL, it never does that.
+ * putenv.c (putenv): Likewise.
+
+ * socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is

+
+2005-11-17 Ludovic Courtès <ludovic.courtes@laas.fr>
+
+ * print.c (EXIT_NESTED_DATA): Before popping from the stack, reset

+
+2005-11-12 Ludovic Courtès <ludovic.courtes@laas.fr>

+
+2005-11-07 Marius Vollmer <mvo@zagadka.de>
+
+ * stime.c (scm_mktime): Use scm_frame_critical_section instead of

+
+ New marking algorithm for weak hashtables that fixes the problem
+ that references from the non-weak value to the associated weak

+
+ Guardians have been changed back to their original semantics and

+
+ * gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak

+ directly.
+
+ * guardians.h, guardians.c, deprecated.h,
+ deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,

+
+2005-07-12 Kevin Ryde <user42@zip.com.au>

+ Reported by Ken Raeburn.
+
+ * gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to

+ changes.
+
+2005-07-10 Kevin Ryde <user42@zip.com.au>
+
+ * socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
+ for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
+ (scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,

+
+2005-07-01 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc-card.c (scm_i_card_statistics): init tag.

+
+2005-06-25 Kevin Ryde <user42@zip.com.au>
+
+ * srfi-13.c (scm_string_filter, scm_string_delete): Partial revert

+
+ * strings.c (scm_take_locale_stringn): Use realloc to make room for

+
+2005-06-12 Marius Vollmer <mvo@zagadka.de>
+
+ * ramap.c (scm_array_index_map_x): First test for real arrays,
+ then check for generalized vectors. This ensures that the
+ generalized vector case need only work with zero-origin ranges.
+ (scm_ra_eqp, scm_ra_compare): Use the new array handle functions
+ to access the target array, making these functions work with all
+ kinds of arrays, not just bit arrays.
+
+ * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
+ gh_list.c, gh_predicates.c: Deprecated everything.

+
+2005-06-10 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * modules.c (s_scm_eval_closure_module): new function. Return the
+ module inside an eval-closure.
+
+ * gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
+ table. This means that procedure properties are GC'd if the
+ procedure dies.
+
+2005-06-11 Kevin Ryde <user42@zip.com.au>
+
+ * srfi-13.c (scm_string_filter, scm_string_delete): For char and
+ charset cases, count chars kept and build a string in a second pass,
+ rather than using a cons cell for every char kept. Use a shared
+ substring when nothing removed (such sharing is allowed by the srfi).
+
+2005-06-09 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
+ string, so live object stats can be sorted with string<?.
+
+2005-06-06 Marius Vollmer <mvo@zagadka.de>
+
+ * print.c (iprin1): When writing a string, collect all characters
+ that can be printed directly into one call to scm_lfwrite.
+ Previously, every character was output with its own call to
+ write(2) on unbuffered ports.
+
+ * eval.c (scm_eval_options_interface): Use
+ scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
+ and SCM_CRITICAL_SECTION_END.
+
+ * unif.c (scm_array_in_bounds_p): First test for real arrays, then
+ check for generalized vectors. This ensures that the generalized
+ vector case need only work with zero-origin ranges.
+
+2005-06-06 Kevin Ryde <user42@zip.com.au>
+
+ * srfi-13.c (scm_string_split): Compare char/char in scan. Mixing an
+ unsigned int SCM_CHAR and a char string meant an 8-bit char was never

+
+ * ramap.c (scm_array_map_x): Allow no source args, add num args checks
+ to subr_1, subr_2, subr_2o and dsubr cases. No source args only has a
+ few sensible uses (like filling with a random number generator say),
+ but has been allowed in the past and so should be kept.
+
+2005-04-23 Kevin Ryde <user42@zip.com.au>
+
+ * hashtab.c (scm_hashx_remove_x): Need to pass "closure" to

+
+2005-04-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>

+
+ * hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
+ argument; always use scm_delq_x. The delete_fn function works on

+ (scm_hash_clear): Accept plain vectors as hashtables.
+ (scm_delx_x): Removed.

+ srfi-60.
+
+ * numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,

+
+ * numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
+ casting inum to double since that can lose precision.
+
+2005-03-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>

+ (scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
+ Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
+ scm_gc_running_p. Do not run the scm_after_gc_c_hook.
+ (scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
+ scm_after_gc_c_hook here.

+ scm_gc_running_p while the scm_i_sweep_mutex is locked.
+
+ * inline.h (scm_cell, scm_double_cell): Do not check

+ not set scm_block_gc.
+
+ * init.c (scm_i_init_guile): Do not set scm_block_gc.

+
+2005-03-08 Marius Vollmer <mvo@zagadka.de>

+ SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
+ they also block/unblock execution of asyncs and call
+ scm_async_click which is declared in async.h but threads.h can not
+ include async.h since async.h already includes threads.h.
+ (scm_i_critical_section_level): New, for checking mistakes in the
+ use of the SCM_CRITICAL_SECTION_* macros.
+ (scm_i_critical_section_mutex): Make it a recursive mutex so that

+ (display_header): Print FNAME when it is true, not

+2004-08-06 Kevin Ryde <user42@zip.com.au>
+
+ * ramap.c (scm_array_fill_x): For byvect char fill, force signed char

+
+ * filesys.c (scm_copy_file): Use fstat on the input fd rather than
+ stat on the filename, to be certain a file rename can't mean we get

+ similar to Emacs copy-file.
+
+ * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
+
+ * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on

+
+2004-07-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * tags.h (scm_is_eq): New.
+
+ * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
+ SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
+ "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
+ scm_from_bool, and scm_is_bool, respectively.
+
+ * boolean.h (scm_is_bool): Fix bug in prototype.
+ (scm_from_bool): The argument is "x" not "f", stupid.
+
+ * boolean.c (scm_is_bool): Fix typo.
+
+ * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
+ scm_is_unsigned_integer, scm_to_signed_integer,

+
+ * boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
+ scm_to_bool): New.
+
+2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * backtrace.c (display_expression, display_frame): Call
+ scm_i_unmemoize_expr for unmemoizing a memoized object holding a
+ single memoized expression.
+
+ * debug.c (memoized_print): Don't try to unmemoize the memoized
+ object, since we can't know whether it holds a single expression
+ or a body.
+
+ (scm_mem_to_proc): Removed check for lambda expression, since it
+ was moot anyway. Whoever uses these functions for debugging
+ purposes should know what they do: Creating invalid memoized code
+ will cause crashes, independent of whether this check is present
+ or not.
+
+ (scm_proc_to_mem): Take the closure's code as it is and don't
+ append a SCM_IM_LAMBDA isym. To allow easier debugging, the
+ memoized code should not be modified.
+
+ * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
+ scm_unmemoize from public use, but made scm_i_unmemoize_expr
+ available as a guile internal function instead. However,
+ scm_i_unmemoize_expr will only work on memoized objects that hold
+ a single memoized expression. It won't work with bodies.
+
+ * debug.c (scm_procedure_source), macros.c (macro_print), print.c
+ (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
+ i. e. a list of expressions.
+
+ * eval.c (unmemoize_exprs): Drop internal body markers from the
+ output during unmemoization.
+
+ * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
+ scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
+ but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
+ as guile internal functions instead. scm_i_unmemoize_expr will
+ only work on a single memoized expression, while
+ scm_i_unmemocopy_body will only work on bodies.
+
+2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (unmemoize_exprs): Handle semi-memoized code.
+
+ (scm_cons_source, scm_primitive_eval): Prefer higher level
+ predicate SCM_FALSEP over SCM_IMP.
+
+2004-06-15 Rob Browning <rlb@defaultvalue.org>
+
+ * script.c (scm_shell_usage): minor phrasing change.
+
+ * gc_os_dep.c: update ifdefery for macosx.
+ (scm_get_stack_base): separate result initialization from
+ declaration to slience warnings with macosx and hp-ux using gcc
+ 3.3. Thanks to Andreas Vögele.
+
+2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
+
+2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * list.[ch] (scm_i_finite_list_copy): New internal function to
+ copy lists that are known to be finite (though not necessarily
+ proper).
+
+ * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
+ a closure's argument list like an expression of a body.
+
+ * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
+ unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
+ unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,

+ unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
+ unmemoize_builtin_macro): New static functions and symbols.
+
+ (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
+ now has a slightly different meaning: The memoized form that is
+ receives as its argument is now interpreted as a sequence of
+ expressions from a body.
+
+ (unmemocar, scm_unmemocar): Since the whole functionality of
+ unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
+ has its old content back and is deprecated, while unmemocar has
+ been removed.
+
+ (SCM_BIT7): Removed.
+
+ (CEVAL): For unmemoizing a single expression, call
+ unmemoize_expression instead of scm_unmemocopy, which now expects
+ a sequence of body expressions. Eliminated unnecessary empty
+ environment frame when executing let* forms. Eliminated
+ unmemoization step from evaluator.
+
+2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
+ macroexp and made static. Added new version of scm_macroexp that
+ emits a deprecation warning and then calls macroexp.
+ (scm_m_undefine): Issue deprecation warning.
+
+2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
+ Modified to make set! work on symbols that represent syntactic
+ keywords.
+
+2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
+ compound expression as lvalue errors.
+
+2004-05-24 Marius Vollmer <mvo@zagadka.de>
+
+ * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
+ WINDER_DATA to a SCM.
+
+2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * goops.c (compute_getters_n_setters, create_standard_classes,
+ scm_add_slot): Compute closures by calling scm_i_eval_x on a
+ lambda expression rather than creating them with scm_closure.
+
+2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
+ misplaced syntactic keywords. This will not work unless guile's
+ defmacro feature is deprecated.
+
+ (scm_m_case): Fixed a bug that caused the list of labels to grow
+ with every case form.
+
+2004-05-19 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_round_number): For inum and big, just return x. For
+ real, use scm_round for 2^54-1 etc problems covered there.
+
+ * numbers.c (trunc): Remove #define to scm_truncate when the C library
+ doesn't provide trunc. This was for when `truncate' was done as a
+ scm_tc7_dsubr, no longer required.
+
+ * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
+ to stack marking call, two parameters and no cast on t->base.
+
+2004-05-18 Marius Vollmer <mvo@zagadka.de>
+
+ * hashtab.c (rehash_after_gc): Bug fix: properly link the
+ processed hashtables back into the weak_hashtables list. Thanks
+ to Bill Schottstaedt!
+
+2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (unmemoize_quote): New static function.
+
+ (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
+ representation of 'quote' and '@slot-ref' to an improper list.
+ This reduces execution time, the number of cells used to hold the
+ memoized code, and thus also reduces garbage collection time.
+
+ (scm_unmemocopy): Use unmemoize_quote for quote expressions.
+
+ (SCM_CEVAL): Changed macro handling to also work with macros that
+ return improper lists. Added an assertion, that the code returned
+ by a macro transformer will not lead to cycles in the memoized
+ code.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ No functional change, just rearrangements of functions within the
+ file.
+
+ * eval.c (scm_ilookup, scm_unbound_variable_key,
+ error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
+ the definitions used for execution, since that's where they will
+ belong to later.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
+ throughout guile, has not been part of an official release yet,
+ and the concept of sloppy predicates has never been a good idea.
+
+ (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
+ SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
+ Simplified.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
+ to make explicit what happens.
+
+2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
+ explicit what happens.
+
+ * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
+ SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
+
+2004-05-11 Marius Vollmer <mvo@zagadka.de>
+
+ * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
+ is indeed a procedure when it isn't a number.
+
+2004-05-10 Marius Vollmer <mvo@zagadka.de>
+
+ Convert floating point numbers into strings with an arbitrary
+ radix. Thanks to Richard Todd!
+
+ * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
+ fit.
+ (fx): Removed.
+ (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
+ number_chars): New, to support variable radices.
+ (idbl2str): Use above instead of the old base-10 only tables.
+ (iflo2str): Pass on new RADIX argument to idbl2str.
+ (scm_number_to_string): Pass radix to iflo2str.
+ (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
+ iflo2str.
+ (scm_init_numbers): Call init_dblprec and init_fx_radix for all
+ possible radices.
+
+2004-05-10 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_logbit_p): Correction to test above the end of an
+ inum. Reported by Jan Konecny.
+
+2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * gc.h (scm_t_cell): Fields are now of type SCM instead of
+ scm_t_bits. Updated all users.
+ (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
+ duplicating the code.
+ (SCM_CELL_OBJECT_LOC): New.
+ (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
+ (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
+
+ * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
+ SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,

+ SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
+ SCM_SMOB_OBJECT_3_LOC): New.
+ * smob.c (scm_i_set_smob_flags): New function.
+
+ * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
+ hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
+ random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
+ Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
+ SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
+ zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
+
+ * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
+ taking the address of SCM_CELL_WORD_1, the latter being no longer
+ an lvalue.
+
+ * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
+ of casting SCM_CELL_WORD_LOC.
+
+2004-05-02 Kevin Ryde <user42@zip.com.au>
+
+ * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
+ --disable-deprecated. Reported by Andreas Vögele.
+
+ * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
+ particular on HP-UX). Reported by Andreas Vögele.
+
+ * list.c (varargs.h): Remove, leave just stdarg.h which is all the
+ code has support for. Fixes building with AIX cc, which is ansi but
+ doesn't define __STDC__. Reported by Keith Crane.
+ (var_start): Remove macro, this variation no longer required.
+ (scm_list_n): Use va_start directly.
+
+2004-05-01 Kevin Ryde <user42@zip.com.au>
+
+ * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
+ is now gone. Reported by Andreas Vögele.
+
+2004-04-28 Kevin Ryde <user42@zip.com.au>
+
+ * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
+ mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
+ ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
+ subscript. Reported by Andreas Vögele.
+ Also cast through unsigned char to avoid passing negatives to those
+ macros if input contains 8-bit values.
+
+ * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
+ corrections to range check for signed numbers. Remove
+ scm_remember_upto_here_1(num) from these checks, since num is used
+ subsequently anyway.
+
+ * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
+ avoid warning from gcc 3.4. Reported by Hyperdivision.
+
+ * numbers.c (scm_bit_extract): Use min instead of MIN.
+ (MIN): Remove, this conflicts with similar macro defined by limits.h
+ on HP-UX. Reported by Andreas Vögele.
+
+ * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
+ particular on HP-UX). Reported by Andreas Vögele.
+
+ * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
+ Reported by Andreas Vögele.
+
+ * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
+ for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
+ by Andreas Vögele.
+
+2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (s_macro_keyword): New static identifier.
+
+ (scm_m_define): Change order to first create binding and
+ evaluating the expression afterwards.
+
+ (scm_m_set_x): Memoize complete set! expression. Only leave
+ symbols if no binding exists at memoization time. Throw error if
+ assigning to a syntactic keyword.
+
+ (lazy_memoize_variable): New function.
+
+ (CEVAL): When execution set!, perform lazy memoization if
+ unmemoized symbol is detected.
+
+ * modules.c (module_variable): Return variables with unbound
+ value.
+
+ * tags.h: Fix comment.
+
+2004-04-25 Kevin Ryde <user42@zip.com.au>
+
+ * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
+ scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
+ in 8-bit locales, and ensures consistency with char-upper-case? and
+ char-lower-case? which already use ctype.h.
+ (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
+ Remove.
+ * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
+
+ * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
+ call. Reported by Hyperdivision.
+
+ * threads.c (scm_yield): Correction, actually call scm_thread_yield.
+ Reported by Hyperdivision.
+
+ * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
+ Hyperdivision.
+
+2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ Hide the implementation of ilocs and isyms in eval.c.
+
+ * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
+ SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
+ SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
+ SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
+ eval.h to eval.c.
+
+ * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
+ SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
+ scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
+ (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
+ scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
+ deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
+ renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
+ renamed to ISYMNUM.
+
+ * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
+ (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
+ Extracted printing of ilocs and isyms to guile internal functions
+ scm_i_print_iloc, scm_i_print_isym of eval.c.
+
+2004-04-22 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
+
+ * numbers.c (scm_round): Test for x already an integer, to avoid bad
+ rounding in x+0.5 when x is a big value already an integer. In
+ certain hardware rounding cases x+0.5 can give an adjacent integer,
+ leading to that as the result, when we really just wanted x itself.
+
+2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
+
+ (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
+ added const qualifiers, cast intentionally unused expressions to
+ void for emphasis, improved comment.
+
+2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
+ scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
+ scm_tc9_flag to scm_tc8_flag. Introduced new identifier
+ scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
+ Defined the tc8-tag for flags to be 0x04, which will mean that
+ SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
+ to the reduced number of bits and the simpler bit pattern for
+ SCM_BOOL_F, certain machines may be able to use more efficient
+ processor instructions to deal with SCM_BOOL_F.
+
+ (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
+ never been defined in a released version, thus no need to
+ deprecate them.
+
+ (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
+ instead of tc9 tags.
+
+ (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
+ of tc9 tags.
+
+ (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
+ could have used this definition.
+
+ (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
+ SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
+ SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
+ as isyms, as special isyms don't exist any more.
+
+2004-04-18 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_readdir): Use readdir_r when available, for thread
+ safety.
+
+ * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
+ explicit swapping code.
+
+2004-04-15 Kevin Ryde <user42@zip.com.au>
+
+ * cpp_sig_symbols.in: Add SIGSYS.
+
+ * list.c (scm_append_x): Use iterative style, to avoid non-tail
+ recursion.
+
+ * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
+ frac/big and frac/frac, use scm_less_p for exact comparison.
+
+ * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
+ with big/inum.
+
+ * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
+
+2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
+
+ * chars.h (scm_init_chars): change scm_{upcase,downcase} to
+ scm_c_{up,down}case.
+ (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
+ when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
+
+2004-04-06 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_ash): Remove stray "}" in docstring.
+
+ * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
+ x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
+ calling mpz_cmp_ui in most cases.
+
+ * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
+ for big == abs(most-negative-fixnum) special case.
+ (abs_most_negative_fixnum): Remove, no longer used.
+
+ * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
+ test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
+ calling (sigaction NSIG).
+
+ * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
+ and fork error cases to do this.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (CEVAL): Don't distinguish between short and long
+ instructions when dispatching - just always dispatch on the
+ instruction code, which is common for short and long instructions.
+ Further, removed unnecessary goto statements and added comment.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_unmemocopy): Don't distinguish between short and

+
+ * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
+ comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
+ 'checkmacro'.
+
+2004-03-31 Kevin Ryde <user42@zip.com.au>
+
+ * simpos.c: Include <signal.h> for SIG_IGN and friends.
+
+2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
+ SCM_DEBUGGINGP:
+
+ * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
+ eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
+ SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
+ single interface that also matches the naming conventions.
+ Probably scm_debug_mode_p should be part of the private interface
+ anyway.
+
+ * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
+ eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
+ scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
+ to scm_debug_mode_p.
+
+
+ Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
+
+ * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
+ (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
+ from debug.h to eval.h.
+
+ * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
+ more, just leave it with setting scm_debug_mode_p, which is
+ equivalent for practical purposes.
+
+ * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
+ instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
+
+ * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
+
+ * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
+ static and renamed it to ceval throughout. Provide a new exported
+ but deprecated function scm_ceval as a wrapper for backwards
+ compatibility. The same is done for the deval/scm_deval pair of
+ functions.
+
+ * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
+ throughout. Defined CEVAL to ceval or deval, based on compilation
+ phase.
+
+ * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
+ to ceval and deval instead of calling *scm_ceval_ptr.
+
+ * eval.c (dispatching_eval): New deprecated static function.
+
+ * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
+ to emulate its old behaviour as closely as possible.
+
+
+ Change the evaluator such that only expressions for which pair? is
+ true are passed to CEVAL, and such that all other expressions are
+ evaluated outside of CEVAL:
+
+ * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
+ expression that is assumed to be memoized already. All but
+ expressions of the form '(<form> <form> ...)' are evaluated inline
+ without calling an evaluator.
+
+ * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
+ expressions of the form '(<form> <form> ...)' inline without
+ calling an evaluator.
+
+ * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
+ the special case of unmemoized symbols passed on the top level.
+
+ * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
+ is known that the expression passed to CEVAL is of the form
+ '(<form> <form> ...)'. Remove handling of the tc7-objects, since
+ now it is known that the input expression of CEVAL is a pair.
+
+2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (is_self_quoting_p): New static function.
+
+ (scm_m_quote): Use is_self_quoting_p.
+
+ (copy_tree): Corrected typo in comment.
+
+2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * eval.c (s_scm_copy_tree): idem.
+
+ * list.c (s_scm_filter): remove "pointer" from doc string.
+
+ * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
+
+ * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
+
+ * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
+ (display_frame): idem.
+ (display_backtrace_file_and_line): idem.
+
+ * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
+ arguments.
+
+2004-03-26 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
+
+ * numbers.c (scm_modulo): For inum/big and big/big, remove test of
+ big==0 since that never occurs.
+
+ * numbers.c, numbers.h (scm_modulo_expt): Renamed from
+ scm_modular_expt, matching scheme level name `modulo-expt'.
+
+ * numbers.c (scm_modular_expt): Return a negative remainder for a
+ negative divisor, the same as `modulo' does.
+
+2004-03-26 Eric Hanchrow <offby1@blarg.net>
+
+ * numbers.c, numbers.h (scm_modular_expt): New function.
+
+2004-03-25 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
+ return inexact as required by r5rs.
+
+2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c: Separated some definitions relevant for execution from
+ the memoization part of the file.
+
+ (copy_tree): New static function
+
+ (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
+ structures are detected now and will lead to an exception instead
+ of forcing guile to run in an endless loop, using up all the
+ system's memory. Second, arrays in the cdr of an improper list
+ are now copied. See the new test cases in eval.test.
+
+2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * posix.c (scm_gethostname): Make sure len is initialised before
+ it is used. Restructured to (hopefully) represent possible
+ configurations more clearly in the code. Added unwind handler.
+
+2004-03-23 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
+ MAXHOSTNAMELEN when available.
+
+2004-03-21 Marius Vollmer <mvo@zagadka.de>
+
+ * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
+ terminator. Rewritten the logic as a state machine, I must have
+ been doing too much VHDL lately...
+
+ * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
+ themselves. Thanks to Han-Wen Nienhuys!
+
+ * list.c: Changed docstrings so that they no longer talk about
+ returning 'pointers' to something.
+
+2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.c: remove set_debug_cell_accesses! when
+ SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
+ use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
+ debugging conditionally.
+
+2004-03-21 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
+
+2004-03-20 Kevin Ryde <user42@zip.com.au>

+ * posix.c (scm_gethostname): Preserve errno across free() call.
+
+2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
+ free cells.
+
+2004-03-14 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
+ (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
+
+2004-03-07 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
+ than "GMT" always.
+ (filltime): Make zname parameter "const".
+
+2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
+
+ * threads.c, threads.h (scm_c_scm2thread): New function.
+
+2004-02-29 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
+ available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
+ particular don't assume "defined (__alpha__) && ! defined (linux)"
+ means OSF. Remove "SCO" code, which was not really SCO specific and
+ which John W. Eaton advises should be long past being needed.
+
+ * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
+ error throw.
+
+2004-02-24 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
+
+2004-02-22 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
+ complex, same as for two args. (Handle only inum, big, real, frac).
+
+2004-02-21 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_crypt): Use new HAVE_CRYPT.
+ (<crypt.h>): Remove HAVE_LIBCRYPT condition.
+ Reported by Andreas Voegele.
+
+2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
+
+ * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
+ validation.
+
+ * read.c (scm_lreadparen): Removed.
+ (scm_lreadparen1): Renamed scm_i_lreadparen.
+
+2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * list.c (scm_list_n): validate non-immediate arguments;
+ this will catch forgotten a SCM_UNDEFINED.
+
+2004-02-18 Marius Vollmer <mvo@zagadka.de>
+
+ * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
+ Thanks to Bill Schottstaedt!
+
+ * socket.h (scm_gethost): Removed prototype it is already in
+ "net_db.h". Thanks to Bill Schottstaedt!
+
+2004-02-18 Kevin Ryde <user42@zip.com.au>
+
+ * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
+ order parameter to mpz_import, in fact with just one word there's no
+ order to worry about at all.
+
+ * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
+ and frac==complex, make an exact comparison rather than converting
+ with fraction2double.
+
+ * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
+ shared library, since environ is not directly available there.
+
+ * script.c (scm_shell_usage): Print to stdout for --help, per GNU
+ standard.
+
+ * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
+ errno EINVAL in case localtime and gmtime don't set it.
+ (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
+ SCM_SYSERROR, since mktime and strptime generally don't set errno.
+
+2004-02-16 Kevin Ryde <kevin@swox.se>
+
+ * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
+ which were permitted in the past for these.
+
+ * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
+ previous change to numbers.c.
+
+ * script.c (scm_shell_usage): Print bug-guile email address, as per

+ code in order to avoid compiler used uninitialized warnings.
+
+ * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
+ scm_hash_map.
+ (scm_hash_fold): Use scm_call_3 directly in the call to
+ scm_internal_hash_fold instead of going via fold_proc (which is
+ now removed).
+ (scm_hash_for_each): Use a trampoline +
+ scm_internal_hash_for_each_handle.
+ (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
+ functions.
+
+2004-02-12 Kevin Ryde <user42@zip.com.au>
+
+ * ports.c (scm_port_line): In docstring, note first line is 0.
+ (scm_set_port_line_x): In docstring, note first line is 0.
+ (scm_port_column): In docstring, there's no default to current input
+ port, and remove shared port-line @defun.
+ (scm_set_port_column_x): In docstring, there's no default to current
+ input port, note first column is 0, remove shared set-port-line!
+ @defun.
+
+ * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
+ convert args the same way that array-set! does.
+
+ * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
+ for dvect.
+ (scm_array_p): Add missing "break"s in switch, fix llvect test look
+ for "l" not "s", fix dvect to be false for singp(prot) since such a
+ value is for fvect.
+ (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
+ (exactly_one_third): New variable.
+ (scm_init_unif): Initialize it.
+
+2004-02-10 Neil Jerram <neil@ossau.uklinux.net>
+
+ * read.c (scm_read_opts): Change `escaped-parens' to
+ `elisp-strings'.
+
+2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
+
+ * read.c (scm_read_opts): New opts `elisp-vectors' and
+ `escaped-parens'.
+ (s_vector): New.
+ (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
+ handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
+ `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
+ Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
+ `escaped-parens' option set.
+ (scm_read_token): If elisp vector syntax active, disallow [ and ]
+ in tokens.
+ (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
+ (scm_lreadparen1): New.
+
+ * read.h: Remove conditionally compiled last arg to
+ scm_lreadparen.
+ (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
+
+2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * eval.c (m_expand_body): remove stray variable new_body.
+
+2004-01-22 Marius Vollmer <mvo@zagadka.de>
+
+ * eval.c (m_expand_body): Rewrite the expression in place (by
+ overwriting FORMS) also when a letrec is constructed, not only
+ when no definitions are found. Do not return rewritten expression
+ to emphasize the in-place rewriting. Changed all users.
+
+2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.c: add protected_object_count, a number that is dumped from
+ gc_stats()
+
+2004-01-11 Marius Vollmer <mvo@zagadka.de>
+
+ * dynwind.h, dynwind.c (scm_frame_unwind,

+ (scm_frame_rewind, scm_frame_rewind_handler): Likewise.
+
+2004-01-11 Kevin Ryde <user42@zip.com.au>
+
+ * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
+ s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
+ changes made to scheme-compound.texi.
+
+2004-01-10 Marius Vollmer <mvo@zagadka.de>
+
+ * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
+ #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
+
+ * guile-snarf.in: Use mkdir to create a unique temporary directory
+ that we can safely use. Thanks to Stefan Nordhausen!
+
+2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
+ argument since it is always zero now. Changed all callers.
+ Removed code for handling fluids.
+
+ * fluids.c (scm_c_with_fluids): Use frames instead of adding to
+ the wind chain explicitely. Use scm_c_with_fluid for the common
+ case of only one fluid.
+ (scm_with_fluid): New.
+ (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
+
+ * fluids.h, fluids.c (scm_frame_fluid): New.
+ (scm_with_fluid): New.
+ (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
+
+ * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
+ do the unwinding directly. It is simple enough.
+
+ * dynwind.h, dynwind.c: Did the following renamings:
+ scm_begin_frame -> scm_frame_begin,
+ scm_end_frame -> scm_frame_end,
+ scm_on_unwind -> scm_frame_unwind,
+ scm_on_rewind -> scm_frame_rewind,
+ scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
+ scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
+ Changed all uses.
+
+ * aync.h, async.c: Did the follwing renamings:
+ scm_with_blocked_asyncs -> scm_frame_block_asyncs,
+ scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
+ Changed all uses.
+
+ * ports.h, ports.c: Did the follwing renamings:
+ scm_with_current_input_port -> scm_frame_current_input_port,
+ scm_with_current_output_port -> scm_frame_current_output_port,

+ Changed all uses.

+2004-01-07 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (s_bignum): Remove, not used since gmp bignums.
+ Reported by Richard Todd.
+
+ * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
+ for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
+
+ * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
+ traversing the args list, fixes segv if an improper list is given.
+ Reported by Rouben Rostamian.
+
+2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
+ swap_data on stack, use a 'malloc obj'.
+
+ * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
+ scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
+ scm_i_... since they are internal. Changed all uses.
+
+ * dynwind.c (frame_print): Removed, use the default printer.
+ (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
+ (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
+ to protect SCM values.
+
+ * dynwind.h (SCM_F_WIND_EXPLICITELY,
+ SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
+ Changed all uses.
+ (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
+
+2004-01-05 Marius Vollmer <mvo@zagadka.de>
+
+ * ports.h, ports.c (scm_with_current_input_port,
+ scm_with_current_output_port, scm_with_current_error_port): New.
+
+ * async.h, async.c (scm_with_blocked_asyncs,
+ scm_with_unblocked_asyncs): New.
+
+2004-01-03 Marius Vollmer <mvo@zagadka.de>
+
+ * dynwind.h, scm_dynwind.c (scm_t_frame_flags, scm_t_wind_flags,
+ scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
+ New.
+ (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
+ scm_i_dowinds and extended to handle frames and to invoke a 'turn'
+ function when the outermost wind point has been reached. The
+ latter is used to copy a continuation stack at the right time.
+ scm_dowinds remains available.
+ (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
+ tc16_guard, guards_print): Removed.
+ (scm_internal_dynamic_wind): Reimplemented using frames.
+
+ * continuations.c (copy_stack): New, do only the stack copying
+ part of copy_stack_and_call.
+ (copy_stack_and_call): Copy the stack after unwinding and before
+ rewinding.
+ (scm_dynthrow): Do not call scm_dowinds, this is now done by
+ copy_stack_and_call.
+
+2004-01-04 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_less_p): Don't convert frac to float for compares,
+ can give bad results due to rounding.
+
+ * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
+ setzone/restorezone protection for DOS.
+
+2003-12-26 Marius Vollmer <mvo@zagadka.de>
+
+ * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax
+ and scm_t_uintmax to be defined in scmconfig.h
+
+2003-12-03 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
+
+ * numbers.c (scm_make_ratio): Check for numerator equal to
+ SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
+ giving integer -1.
+
+ * numbers.c (scm_real_part): Return fraction unchanged rather than
+ converting to flonum.
+
+2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * modules.c (module_variable): Fixed (and thus simplified) the
+ definition of SCM_BOUND_THING_P to reflect the fact that since
+ after the 1.4 series of guile, obarrays only hold variable
+ objects.
+
+2003-11-30 Marius Vollmer <mvo@zagadka.de>
+
+ * numbers.c (scm_logand): It's "#b...", not "#\b...".
+
+ From Paul Jarc:
+
+ * read.c (scm_lreadr): Signal an error for invalid escape
+ sequences in strings. Code cleanups too.
+
+ * print.c (scm_iprin1): use \xNN hexadecimal sequences when
+ writing control characters in strings.
+
+2003-11-21 Marius Vollmer <mvo@zagadka.de>
+
+ * ports.c (scm_drain_input): Bug fix: only access the port after
+ checking that it indeed is one.
+
+2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * eval.c (s_bad_define): New static identifier.
+
+ (m_body): Fixed comment.
+
+ (scm_m_define): Don't generate memoized code for definitions that
+ are not on the top level. As a consequence, no memoized code at
+ all is generated for definitions any more: Top level definitions
+ are executed immediately during memoization and internal
+ definitions are handled separately in m_expand_body.
+
+ (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
+ definitions. Consequently, there is no unmemoizing code any more
+ that might modify the environment. Thus, the old scm_unmemocopy
+ is removed and the old unmemocopy is renamed to scm_unmemocopy.
+
+ (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
+ memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
+ over SCM_NIMP in places, where the argument is known to be part of
+ a proper list.
+
+2003-11-21 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_abs): Allocate a new real only for negatives, as done
+ for bignums.
+
+ * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
+ to share some shifting.
+
+ * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
+ scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
+ since gc does this.
+
+2003-11-19 Marius Vollmer <mvo@zagadka.de>

+ specific. The goal is to remove definitions of evaluator

+
+ * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.

+
+2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * tags.h: Reduced the number of short instructions from 14 to 13.
+ The typecode of the former 14th short instruction is now used to

+
+ (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
+ previously used by SCM_IM_DEFINE.
+
+ (SCM_IM_DEFINE): Turned into a long instruction.
+
+ * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long

+
+ * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
+ 0.0==some_expression to some_expression==0.0. The latter is
+ better readable. The former is preferred by some people, since it
+ leads to a compiler error when confusing == with =. However, when

+ assigment appears. Since many Guile developers are using gcc,
+ such errors will not remain unnoticed anyway. We can therefore
+ focus on better readability.

+2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * __scm.h: Reformulated the architecture and compiler properties

+ This set of patches separates the representation of the cxr family

+ * posix.c (s_scm_putenv): Disable use of unsetenv() for the
+ mingw32 build.

+ The purpose of this patch is to make guile's internal memoizers
+ distinguishable from memoizing macros created on the scheme level
+ or from user provided primitive memoizing macros. The reason is,
+ that the internal memoizers are the only ones that are allowed to
+ transform their scheme input into memoizer byte code, while all
+ other memoizing macros may only transform scheme code into new
+ scheme code.
+
+ To achieve this, a new macro type 'builtin-macro!' is introduced.
+ Currently, 'builtin-macro!'s are handled as memoizing macros, but
+ this will change when the memoizer and executor are separated.
+
+ * macros.[ch] (scm_i_makbimacro): New.

+ * macros.h (SCM_BUILTIN_MACRO_P): New.
+
+ * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.

+ primitive builtin-macros now.
+
+ * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
+ builtin-macros are handled equally to memoizing macros.
+
+2003-05-04 Marius Vollmer <mvo@zagadka.de>

+
+ This fixes a serious GC bug, introduced during the latest

+ GOOPS objects:
+
+ * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
+ SCM_EOL.
+ (scm_struct_prehistory): Move scm_free_structs to
+ scm_before_mark_c_hook.
+
+ * gc-card.c (sweep_card): Check that we haven't swept structs on
+ this card before. That can happen if scm_i_sweep_all_segments has
+ been called from some other place than scm_igc.
+
+2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
+ (since hash tables now adapt their size).
+
+ * modules.c (scm_modules_prehistory): Changed from 2001 to 1533

+
+ The following changes introduce the use of resizable hash tables
+ throughout Guile. It also renames the old *-hash-table* functions
+ to *-alist-vector* and places them, together with the rest of the
+ weak vector support, in the module (ice-9 weak-vector). We should
+ probably introduce a new, better, API for weak references, for
+ example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
+ look like and are used like ordinary pairs.)
+
+ * environments.c (obarray_enter, obarray_retrieve, obarray_remove,

+ SCM_WVECT_NOSCAN_P): New macros.
+
+ * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
+ and SCM_WVECT_WEAK_VALUE_P.
+
+ * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from

+
+2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ * hashtab.c: Undid thread safety. (We decided that it's better to

+ is suitable for the application.)
+
+2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made

+ SCM_DEFER/ALLOW_INTS.
+
+2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+

+
+ * weaks.c (scm_make_weak_key_hash_table,

+ futures.
+ (scan_futures, cleanup_undead): Be smarter about marking
+ futures---avoid unnecessary passes through future lists.
+
+ * futures.h, futures.c: New files; Introduced recycling of

+ is not currently defined, and there isn't even a configure switch
+ to enable it yet.)
+
+2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
+ builds work.
+ (EXTRA_DIST): Added version.h.in.
+
+2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ This change makes it possible for one thread to do lazy sweeping
+ while other threads are running. Now only the mark phase need to
+ have all threads asleep. We should look further into this issue.
+ Presently, I've put the locking of scm_i_sweep_mutex at
+ "conservative" places due to my current lack of knowledge about
+ the garbage collector. Please feel free to restrict these regions
+ further to allow for maximal parallelism!
+
+ * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
+
+ * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
+ scm_gc_register_collectable_memory): Substitute locking of
+ scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
+ (scm_igc): Lock sweep mutex here instead of in callers; Calls to
+ scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
+ the single-thread section (which now only contains the mark
+ phase).
+ (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
+ Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
+
+ * threads.c (gc_section_mutex): Removed.

+ (scm_trampoline_1, scm_trampoline_2): Use them.
+
+2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
+
+ Partial introduction of real plugin interface.
+
+ * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
+ (EXTRA_DIST): Added threads-plugin.c.
+
+ * threads-plugin.h, threads-plugin.c: New files.
+
+ * threads.h: #include "libguile/threads-plugin.h".
+
+ * threads.c: #include "libguile/threads-plugin.c".
+
+ * pthread-threads.c: Temporarily remove debugging functions.
+
+ * threads.c, threads.h (scm_yield): Added back.
+
+2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
+
+ * threads.c (really_launch): Detach before unlocking
+ thread_admin_mutex in order not to risk being joined.
+ (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
+ thread_admin_mutex locked during GC.
+
+ * pthread-threads.c, pthread-threads.h: Improvements to debugging

+ (scm_all_threads): Return copy of thread list (to prevent
+ unintended destruction).
+ (scm_threads_prehistory): Initialize heap_mutex of fake thread.
+
+ * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
+ pthread "native" recursive mutex support.
+
+2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
+ Simply lock a thread C API recursive mutex.
+ (SCM_NONREC_CRITICAL_SECTION_START,
+ SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
+ SCM_REC_CRITICAL_SECTION_END): Removed.
+
+ * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
+ direct calls to scm_rec_mutex_lock / unlock around the three calls
+ to scm_m_expand_body.
+
+ * eval.c, eval.h (promise_free): New function.
+ (scm_force): Rewritten; Now thread-safe; Removed
+ SCM_DEFER/ALLOW_INTS.
+
+ * pthread-threads.h: Added partially implemented plugin interface
+ for recursive mutexes. These are, for now, only intended to be
+ used internally within the Guile implementation.
+
+ * pthread-threads.c: New file.
+
+ * threads.c: Conditionally #include "pthread-threads.c".
+
+ * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
+ thread-safe;
+
+ * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,

+
+ * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section

+ committed by mistake.
+
+2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
+
+ * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
+ 2002-12-10.
+
+ * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
+
+ * gc.c (scm_gc_sweep): Call it here instead, which is a more
+ logical place.
+
+ * threads.c (create_thread): Remember root object until the handle
+ of the new thread is on all_threads list.
+
+ * root.c (scm_make_root): Moved copying of fluids until after
+ creation of root handle so that the fluids are GC protected. Also
+ removed the critical section.
+
+2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
+
+ * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.

+ (scm_gc_malloc_prehistory): Initialize it.
+ (scm_realloc): Serialize call to realloc

+
+ * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
+
+ * threads.c (really_launch): Release heap (to prevent deadlock).

+
+2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
+

+ in srcdir.
+
+2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ These changes remove scm_ints_disabled (which hasn't has any
+ effect in Guile for quite some time).
+
+ * async.c, error.h (scm_ints_disabled): Removed.
+
+ * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
+ root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
+ SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.

+ * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
+ critical section.
+ (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
+ SCM_ALLOW_INTS.
+
+2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
+ Removed accidental #if 0 around these functions.
+
+ These changes are the start of support for preemptive
+ multithreading. Marius and I have agreed that I commit this code
+ into the repository although it isn't thoroughly tested and surely
+ introduces many bugs. The bugs should only be exposed when using
+ threads, though. Signalling and error handling for threads is
+ very likely broken. Work on making the implementation cleaner and
+ more efficient is needed.
+
+ * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
+ (SCM_NONREC_CRITICAL_SECTION_START,
+ SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
+ SCM_REC_CRITICAL_SECTION_END): New macros.
+ (SCM_CRITICAL_SECTION_START/END): Defined here.
+
+ * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
+ the three calls to scm_m_expand_body.
+
+ * gc.h: #include "libguile/pthread-threads.h";
+ (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
+
+ * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
+ scm_t_key;
+
+ * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
+ access.
+
+ * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
+
+ * gc-freelist.c, threads.c (really_launch): Use
+ SCM_FREELIST_CREATE.
+
+ * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
+
+ * gc.c (scm_i_expensive_validation_check, scm_gc,
+ scm_gc_for_newcell): Put threads to sleep before doing GC-related
+ heap administration so that those pieces of code are executed
+ single-threaded. We might consider rewriting these code sections
+ in terms of a "call_gc_code_singly_threaded" construct instead of
+ calling the pair of scm_i_thread_put_to_sleep () and
+ scm_i_thread_wake_up (). Also, we would want to have as many of
+ these sections eleminated.
+
+ * init.c (scm_init_guile_1): Call scm_threads_prehistory.
+
+ * inline.h: #include "libguile/threads.h"
+
+ * pthread-threads.h: Macros now conform more closely to the
+ pthreads interface. Some of them now take a second argument.
+
+ * threads.c, threads.h: Many changes.
+
+2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
+
+ * Makefile.am (version.h): Changed $^ --> $< in rule for

+
+ * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
+ (SCM_MINOR_VERSION): use @--@ substitution now.
+ (SCM_MICRO_VERSION): use @--@ substitution now.
+ (scm_effective_version): new function prototype.
+
+ * version.c (scm_effective_version): new function, also add
+ effective-version.
+
+ * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
+ (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
+ SCM_LIBRARY_DIR.
+ (version.h): generate this here rather than configure.in. This
+ approach tracks source edits better (i.e. more immediately).
+ Might be worth considering for other .in files too.
+
+2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Reorganized thread package selection. A thread package now only
+ implements a small set of pthread like functions and Guile
+ implements the rest on top of that. Guile's implementation is
+ what the "coop-pthreads" package has been previously. Support for
+ "coop" threads has been removed until I get time to add it again.
+
+ * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
+ (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
+ null-threads.c, coop-pthreads.c.
+ (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
+ pthread-threads.h.
+
+ * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
+
+ * threads.h: Do not include "libguile/coop-defs.h". Include
+ "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
+ (previously deprecated) C level thread API prototypes. They are
+ now in the thread package specific headers, "null-threads.h" and
+ "pthread-threads.h".
+ (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
+ New.
+ (scm_threads_init): Removed.
+ (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
+ SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
+ SCM_I_THREAD_SWITCH_COUNT): Define here.
+ (scm_single_thread_p): Removed.
+ (scm_call_with_new_thread): Take two args directly instead of list
+ of two args.
+ (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
+ SCM_SET_THREAD_LOCAL_DATA): Define here.
+
+ * threads.c: Merged with "coop-pthreads.c".
+
+ * null-threads.h: Implement pthread-like API as a set of macros.
+
+ * pthread-threads.h: New, implement pthread-like API by deferring
+ to pthread itself.
+
+ * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
+ has been lost in the reorganization.
+
+2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
+
+ The following change makes it possible to move procedure
+ application dispatch outside inner loops. The motivation was
+ clean implementation of efficient replacements of R5RS primitives
+ in SRFI-1.
+
+ The semantics is clear: scm_trampoline_N returns an optimized
+ version of scm_call_N (or NULL if the procedure isn't applicable
+ on N args).
+
+ Applying the optimization to map and for-each increases efficiency
+ noticeably. For example, (map abs ls) is 8 times faster than
+ before.
+
+ * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
+
+ * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
+
+ * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
+ (map, for-each): Handle also application on two args as a special
+ case; Use trampolines.
+
+ Other changes:
+
+ * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
+ (subr2oless): Removed.
+ (scm_restricted_vector_sort_x): Use scm_return_first to keep the
+ vector GC protected.
+
+ * eval.c (check_map_args): Use scm_out_of_range_pos instead of
+ scm_out_of_range.
+
+2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
+
+2002-11-17 Mikael Djurfeldt <mdj@linnaeus>
+
+ * debug.c (scm_make_iloc): Added missing "return".
+
+2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * strports.c (scm_eval_string_in_module): Validate second arg to
+ be a module. Thanks to Arno Peters!

+ module_variable, scm_module_lookup_closure,
+ scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
+ scm_system_module_env_p): Don't compare SCM values with C
+ operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
+ over SCM_NFALSEP.
+
+2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * eval.h (SCM_MAKE_ILOC): New macro.
+
+ * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing
+ the iloc bitpattern here.
+
+2002-11-14 Mikael Djurfeldt <mdj@linnaeus>
+
+ * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
+ part of the API, otherwise it's difficult to write Guile
+ extensions using non-blocking I/O => moved #include
+ "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
+
+ * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
+ s_unlock_mutex.
+
+2002-11-10 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They
+ are defined in configure.in.
+
+ * threads.c: Removed SCM_API from function definitions. SCM_API
+ is only for declarations.
+
+2002-11-07 Mikael Djurfeldt <mdj@linnaeus>
+
+ * coop-pthreads.h: Added support for thread specific data to the
+ generic C API for the coop-pthreads case.
+
+ * threads.c, threads.h (scm_cond_init): Undo unintentional API
+ change.
+ (scm_cond_broadcast): Added missing function.
+
+2002-11-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
+
+ * coop.c (coop_next_runnable_thread): Removed, wich should have
+ happened when GUILE_ISELECT was hard-wired.
+
+2002-11-03 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * Makefile.am (libguile_la_SOURCES): Added threads.c
+ (DOT_DOC_FILES): Added threads.doc.
+ (DOT_X_FILES): Added threads.x.
+ (EXTRA_libguile_la_SOURCES): Removed threads.c.
+ (noinst_HEADERS): Added coop-pthreads.c.
+ (modinclude_HEADERS): Added coop-pthreads.h.
+
+ * __scm.h (USE_THREADS, GUILE_ISELECT): Define when
+ SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile.
+
+ * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
+ Thanks to Bill Schottstaedt!
+
+ * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.
+
+ * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
+ SCM_COPT_THREADS is defined.
+ (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS
+ is defined.
+
+ * coop-pthreads.c: Some harmless renamings of internal stuff.
+ (create_thread): New, generalized version of
+ scm_call_with_new_thread.
+ (scm_call_with_new_thread): Use it.
+ (scm_spawn_thread): New, use create_thread.
+
+2002-11-02 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * coop-pthreads.c, coop-pthreads.h: Redone completely, you might
+ start testing it now.
+
+ * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
+ defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
+ (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
+ is defined.
+
+2002-10-27 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * scmsigs.c (signal_cell_handlers, install_handler_data,

+ (scm_sigaction_for_thread): Use new Scheme. Validate that thread
+ hasn't exited yet.

+ * async.c (scm_async_click): Reset pending_asyncs, handle
+ signal_asyncs. Don't set cdr of a non-signal async to #f.
+ (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
+ always. Set pending_asyncs.
+ (scm_system_async_mark_for_thread): Check that thread has not
+ exited.
+ (scm_unmask_signals, decrease_block): Call scm_async_click after
+ block_asyncs becomes zero.
+
+ * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of
+ active_asyncs.
+
+ * root.h (scm_root_state): Added pending_asyncs and signal_asyncs
+ fields.
+ * root.c (root_mark): Mark them.

+ one for USE_NULL_THREADS.
+ (scm_init_iselect): Likewise.
+
+ * inline.h (scm_cell, scm_double_cell): Also allow
+ USE_COPT_THREADS to not protect the slot initializers.
+
+ * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
+ because threads need to be initialized before the stack, but
+ gsubrs such as scm_timed_condition_variable_wait can only be
+ created later.
+
+ * threads.h: Include "coop-pthreads.h" when requested.
+ (scm_threads_make_mutex, scm_threads_lock_mutex,

+ Deprecated the special kind of built-in dynamic syntax transformer

+
+2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
+

+
+2002-07-12 Gary Houston <ghouston@arglist.com>
+
+ * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
+ defined. They don't do anything useful, especially since the

+ when --with-modules=no is given to configure, which is basically
+ requesting that the "dynamic linking module" be omitted.
+
+ * Makefile.am (libguile_la_SOURCES): move dynl.c from

+
+ * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to

+
+ * posix.c (scm_convert_exec_args), dynl.c
+ (scm_make_argv_from_stringlist): static procs: 1) renamed both to

+ strings, just make an array of pointers 3) avoid memory leaks on
+ error 4) let the procedure report errors in its own name.
+ Consequences: 1) the procedures now assume that SCM strings are
+ nul-terminated, which should always be the case. 2) Since strings
+ are not reallocated, it's now possible for strings passed to
+ dynamic-args-call to be mutated.
+
+2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * __scm.h, eval.c, eval.h: Removed compile time option
+ MEMOIZE_LOCALS to clean up the code. Now, caching of local
+ variable positions during memoization is mandatory. However, the
+ option to disable the caching has most probably not been used
+ anyway.
+
+2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>

+ (scm_even_p, scm_odd_p): Treat infinity as even and odd.
+ (iflo2str): Don't output a '+' for negative numbers or for Inf and

+
+2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * guile-snarf.in: Do not clean input file. This would write to
+ the $(srcdir) during a VPATH build, which is not allowed. It also
+ isn't needed since it only works when an output filename has been

+ because the output file will already exist.
+
+2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>

+ stdout. When no "-o" option is given, use "-" as the output

+
+2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>

+ (scm_eval_options_interface), read.c (scm_read_options): Change
+ incorrect @var in docstring to @code.
+
+2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.

+
+2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

+ configure time.
+
+ * num2integral.i.c: Adapt to new interface.
+ (NUM2INTEGRAL): Test whether a fixnum can be represented in the
+ target type by casting it and checking whether it is still the
+ same. Do not try to handle bignums for integral types that are
+ smaller than fixnums. When handling bignums, collect the
+ magnituse first into a unsigned type, and correctly check for
+ overflow.
+ (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
+ only -MIN_VALUE can still be negative of all negative numbers (in
+ twos-complement).
+
+ * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
+
+ * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and

+
+2001-11-07 Stefan Jahn <stefan@lkcc.org>
+
+ * win32-socket.[ch]: New files. Defines Winsock-API error codes
+ and makes them available through Guile. That is because the
+ Winsock-API does not store its errors in `errno' and thus cannot
+ return error messages via `strerror (errno)'.
+
+ * socket.c (scm_init_socket): Initialize `win32-socket' part
+ here under M$-Windows.
+
+ * numbers.h: Added missing declaration of
+ `scm_sys_check_number_conversions()'.
+
+ * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
+ and use in `(strerror)' and `(system-error)'.
+
+ * Makefile.am (EXTRA_libguile_la_SOURCES): Added
+ `win32-socket.[ch]' to extra source and header files.
+
+2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
+ a call to turn-on-debugging when --debug has been given instead of
+ turning it on directly. Also, handle new `--no-debug' option,
+ which might suppress the call to turn-on-debugging.
+
+2001-11-05 Stefan Jahn <stefan@lkcc.org>
+
+ * struct.c (s_scm_struct_vtable_p): Corrected docstring.
+
+2001-11-04 Stefan Jahn <stefan@lkcc.org>
+
+ * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
+ here (was at guile_LDADD) which describes the dependency
+ correctly and allows a clean build on Win32.
+
+ * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
+ into FOO.
+
+ * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
+ import macros for external libraries (libcrypt, libqthreads,
+ libreadline and libregex).
+
+ * coop-defs.h: Include <winsock2.h> for `struct timeval'.
+
+ * posix.c (flock): Added support for flock() in M$-Windows.
+
+ * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead

+
+ * fports.c (getflags): Differentiate reading and writing pipes
+ descriptors.
+
+ * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
+ M$-Windows.
+
+ * coop.c (coop_condition_variable_timed_wait_mutex): Use
+ conditionalized error code if `ETIMEDOUT' is not available.
+ (scm_thread_usleep): Remove bogus declaration of `struct timeval
+ timeout'.
+
+ * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
+ belongs. That is because NO_PREPRO_MAGIC gets undefined after
+ each inclusion of `num2integral.i.c'.
+ (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
+
+2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>

+
+2001-11-02 Mikael Djurfeldt <mdj@linnaeus>

+2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Support for native Win32. Thanks to Stefan Jahn!
+
+ * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
+ and win32-dirent.h to extra source and header files. These
+ include the uname() and the POSIX dirent interface implementation
+ for M$-Windows. Put `-no-undefined' into LDFLAGS to support
+ linkers which do not allow unresolved symbols inside shared
+ libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
+ dependency.
+
+ * __scm.h: Defined SCM_API. This macro gets prepended to all
+ function and data definitions which should be exported or imported
+ in the resulting dynamic link library in the Win32 port.
+
+ * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
+ chars.h, continuations.h, coop-defs.h, coop-threads.h,

+ Prefixed each each exported symbol with SCM_API.
+
+ * continuations.c: Added comment about the use of the extern
+ declarations of {get,set}context() functions used in the ia64 port.
+
+ * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
+ is meant to be a `unsigned long *'.
+
+ * filesys.c: Include `direct.h' if possible. Use local
+ `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
+ macros for M$-Windows. Implementation of `fstat_Win32()' which is
+ able to differentiate between sockets and other file descriptors.
+ Use this function as wrapper in `scm_fstat()'. Fixed typo in
+ `scm_dirname()'.
+
+ * fports.c: Include `io.h' is possible. Put `*fp' into referring
+ statement block in `scm_fport_buffer_add()'.
+ Some corrections in `getflags()'.
+
+ * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
+
+ * guile.c: Make sure to define __SCM_IMPORT__ for shared library
+ build on Win32. Disable preloaded symbols on Win2 platforms.
+
+ * ioext.c, ports.c: Include `io.h' is possible.
+
+ * mkstemp.c: Include `process.h' is possible.
+
+ * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
+ too.
+ Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
+
+ * posix.c: Remove unnecessary dirent includes and defines. Include
+ local `win32-uname.h' for MinGW. Extern declaration of
+ `mkstemp()' for systems where it does not exists. Make
+ `getlogin()' available on M$-Windows.
+
+ * scmsigs.c: Made `usleep()' avalable on MinGW.
+
+ * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
+
+ * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
+
+ * win32-uname.c: Include "win32-uname.h", not "uname.h".
+
+2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
+
+ * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
+ Don't apply scm_uniform_vector_length on arrays.
+
+2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
+ scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
+ scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
+ SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer

+
+ (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
+ scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
+ SCM_C[AD][AD]R instead of explicit form.
+
+ (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
+ comparison parameters.
+
+ (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
+ !SCM_NULLP instead of SCM_NIMP.
+
+ (scm_m_case): Don't copy the form. Renamed proc to clause and
+ minimized its scope. Renamed x to clauses. Removed side
+ effecting operation from macro call.
+
+ (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
+ minimized its scope. Renamed x to clauses. Minimized the scope
+ of variable 'len'. Make sure the else clause is treated specially
+ even in case of '=>' occurences. Don't change the else to #t in
+ order to be able to distinguish this case in the evaluator. Leave
+ type checking of the recipient to the evaluator.
+
+ (scm_c_improper_memq): Made the comment somewhat clearer.
+
+ (scm_m_lambda): Renamed proc to formals. Removed unnecessary
+ test for SCM_IM_LET at the place of the formal parameters.
+ Simplified the formal parameter checking.
+
+ (scm_m_letstar): Added Comment. Renamed proc to bindings.
+ Renamed arg1 to binding and minimized its scope. Eliminated
+ unnecessary consing.
+
+ (scm_m_do): Renamed proc to bindings. Minimized the scope of
+ variable 'len'.
+
+ (build_binding_list): New static function.
+
+ (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
+ Further, split up the 'letrec' unmemoizing code to the
+ corresponding parts for 'do', 'let' and 'letrec', adding comments
+ to each form. Cleanup the handling of the do form (This removes
+ some *real* code :-).
+
+ (SCM_CEVAL): Removed side effecting operation from macro call.
+ Handle the 'else clause of the 'cond form specially - the symbol
+ 'else is not replaced with #t any more.
+
+2001-10-14 Gary Houston <ghouston@arglist.com>
+
+ * version.c (scm_version): use sprintf instead of snprintf,
+ for portability. thanks to Bill Schottstaedt.
+
+2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
+
+ * read.c (scm_lreadr): When user-defined hash procedure returns
+ SCM_UNSPECIFIED: Fall back to standard handling instead of raising
+ an exception. (This prevents parsing of uniform vectors from
+ interfering with parsing of numbers.)
+
+2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
+ PTRDIFF_MIN. Thanks to Ken Raeburn.
+
+2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
+
+ * eval.c (scm_m_atbind): First try to find the variable without
+ defining it locally; when it has not been found, define it
+ locally.
+
+ * modules.c (module_variable): Pass over variables that exist but
+ are unbound.
+
+2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * backtrace.c (display_backtrace_file_and_line): Only use
+ scm_basename when POSIX support is compiled in. Thanks to Chris
+ Cramer.
+
+2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.c (mem2uinteger): Return number read so far when coming
+ across a hexdigit after having read a # or if not reading a hex
+ value. This will enable the calling code to correctly handle
+ forms like 1e2. (The background is, that the exponent markers d,
+ e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
+ providing this patch.
+
+ (mem2complex): Fix erroneous double-negation. Now, numbers like
+ 1-i will be read correctly.
+
+2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
+
+ * debug.c (scm_mem_to_proc): Fixed typo in previous change.
+
+ * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
+
+2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * print.c (scm_print_state_vtable, print_state_pool):
+ Initialize. These variables are now registered as gc roots.
+
+ (scm_current_pstate): Update documentation.
+
+ (scm_current_pstate, scm_make_print_state, scm_free_print_state,
+ scm_prin1, scm_init_print): print_state_pool is registered as a
+ gc root and thus does not need to be protected by a surrounding
+ pair any more.
+
+ (make_print_state): The car of print_state_pool no longer holds
+ the scm_print_state_vtable.
+
+ (scm_current_pstate, scm_make_print_state, print_circref,
+ scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
+ SCM_N<foo>.
+
+ (scm_prin1): When building lists, prefer scm_list_<n> over
+ scm_cons[2]?.
+
+ (scm_iprlist): Removed a redundant SCM_IMP test.
+
+ (scm_simple_format): Use SCM_EQ_P to compare SCM values.
+
+2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
+
+ (scm_memcons, scm_mem_to_proc): When building lists, prefer
+ scm_list_<n> over scm_cons[2]?.
+
+ (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
+
+ (scm_procedure_name): Use SCM_CADR instead of explicit form.
+
+ (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
+ Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
+ for some reason his patch didn't make it into the cvs.
+
+2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
+ little bit - should even be somewhat more accurate now.
+
+2001-10-08 Rob Browning <rlb@defaultvalue.org>
+
+ * gc.c: support ia64 register backing store.
+ (SCM_MARK_BACKING_STORE): new macro.
+
+ * continuations.h: support ia64 register backing store.
+ (struct scm_t_contregs): add ia64 register backing store.
+
+ * continuations.c: support ia64 register backing store.
+ (continuation_mark): mark ia64 register backing store.
+ (continuation_free): free ia64 register backing store.
+ (scm_make_continuation): capture ia64 register backing store.
+ (copy_stack_and_call): copy ia64 register backing store.
+
+2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
+ is known to be #f if no entry is found. Thus, use !SCM_FALSEP
+ instead of SCM_NIMP to test for that case.
+
+ * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
+ scm_t_bits instead of long.
+
+2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
+ SCM_T_SIGNED_BITS_MIN): New.
+ * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
+ Use them to make these macros computable by the preprocessor.
+
+ * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
+ whether the integral type fits in a fixnum, not the compiler.
+ This removes a spurious compiler warning. Also, honor the
+ NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
+ needed for `long long's.
+
+ * numbers.c: Define NO_PREPRO_MAGOC when including
+ num2integral.c.i for `long long' and `signed long long'.
+
+2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
+
+ These changes fixes a race condition in the Guile coop - pthread
+ compatibility code.
+
+ * coop.c (mother_awake_p): New variable.
+ (coop_create): Set mother_awake_p before creating or signalling
+ mother; wait until mother is going to sleep before returning.
+ (mother): Reset mother_awake_p before going to sleep.
+
+2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * options.c (protected_objects, scm_init_options): The content of
+ protected_objects is now protected from garbage collection using
+ scm_gc_register_root instead of scm_permanent_object.
+
+ (get_option_setting): New static function that computes an option
+ setting as it was formerly done in the function scm_options.
+
+ (get_documented_option_setting): New static function that
+ returns option documentation as it was formerly done in the
+ function scm_options. Note that documentation C strings are no
+ longer precomputed into SCM objects. Instead, they are converted
+ into SCM strings every time get_documented_option_setting is
+ called.
+
+ (change_option_setting): New static functions that modifies the
+ option setting as it was formerly done in the function
+ scm_options. The function is now exception safe, i. e. won't
+ cause a memory leak when interrupted. Further, only non-immediate
+ option values are added to the protection list.
+
+ (scm_options): This function now has only the purpose to dispatch
+ to to get_option_setting, get_documented_option_setting or
+ change_option_setting, depending on the arguments given to
+ scm_options.
+
+ (scm_init_opts): Don't convert documentation C strings into SCM
+ strings. Further, don't protect any object values: They _must_
+ be immediate values, otherwise there is no guarantee that they
+ have not been collected before anyway.
+
+ * options.[ch] (scm_t_option): Made type unsigned, name into a
+ constant char* and val into a scm_t_bits type.
+
+ (scm_options, scm_init_opts): The number of options is guaranteed
+ to be larger or equal to zero. Thus, the type is changed to
+ unsigned.
+
+2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
+ testing an unsigned value for being >= 0.
+
+2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.h: Removed old comment about using SCM_CAR to access
+ non-pair cells.
+
+ (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
+ the return value is signed. Thanks to Brian Crowder for the bug
+ report.
+
+ (SCM_SRS): Avoid unnecessary casting and don't unpack input
+ values. With this patch, SCM_SRS can be safely used for other
+ types than scm_t_signed_bits. However, it should still better be
+ an internal macro and thus be renamed to SCM_I_SRS.
+
+ (SCM_MAKINUM, SCM_INUM): Use proper casting.
+
+2001-10-03 Gary Houston <ghouston@arglist.com>
+
+ * continuations.h, unif.h: in the descriptions of the bit patterns
+ of the heap cells, make bit 0 the least significant.
+
+2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
+
+ * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
+ Thanks to Golubev I. N.
+
+2001-09-25 Gary Houston <ghouston@arglist.com>
+
+ * ports.c (scm_drain_input): extended the docstring. thanks to
+ Alex Schroeder and Thien-Thi Nguyen.
+
+2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
+
+ * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
+ SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
+ macros. (The NUM names might soon change.)
+
+ * numbers.h: Added missing declarations.
+
+2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
+
+ * Makefile.am: Distribute num2float.i.c.
+
+ * num2float.i.c: New file, multiply included by numbers.c, used
+ to "templatize" the float <-> num conversion routines.
+
+ * numbers.c: New functions: scm_num2float, scm_float2num,
+ scm_num2double, scm_double2num.
+
+2001-09-21 Rob Browning <rlb@defaultvalue.org>
+
+ * .cvsignore: really add version.h
+
+ * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
+ Otherwise it fails on the alpha. However, we might rather choose
+ this size conditionally.
+
+ * numbers.c (scm_gcd): change "k" to a long from an int.
+ Otherwise it fails on the alpha. However, we might rather choose
+ this size conditionally.
+
+ * error.c (scm_wta): coerce char* to intptr_t before int
+ assignment.
+
+ * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
+ int.
+
+ * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
+
+2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
+

+
+2001-09-20 Rob Browning <rlb@defaultvalue.org>
+
+ * .cvsignore: add version.h
+
+ * versiondat.h.in: removed (obsolete).
+
+ * version.h.in: renamed from version.h.
+ (SCM_GUILE_MAJOR_VERSION): new public macro.
+ (SCM_GUILE_MINOR_VERSION): new public macro.
+ (SCM_GUILE_MICRO_VERSION): new public macro.
+
+ * version.h: renamed to version.h.in.
+
+ * version.c
+ (scm_major_version): support integer *_VERSION macros.
+ (scm_minor_version): support integer *_VERSION macros.
+ (scm_micro_version): support integer *_VERSION macros.
+ (scm_version): support integer *_VERSION macros.
+
+2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
+
+ * error.c, error.h: Made error keys globally accessible.
+ Applications might want to test for these or use them in a direct
+ call to scm_error.
+
+ * num2integral.i.c (NUM2INTEGRAL): Report an error when these
+ routines are passed an inexact. This change in behavior is
+ motivated by concordance with R5RS: It is more common that a
+ primitive doesn't want to accept an inexact for an exact.
+
+2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ The following patch partially undoes my patch from 2001-06-30,
+ where I added the function scm_gc_mark_cell_conservatively. The
+ function is buggy, since it breaks guile during conservative
+ marking if a pointer on the stack points directly into the list of
+ free cells on the heap: With conservative cell marking this will
+ cause the whole free list to be scanned and marked - boom!
+
+ * gc.c (allocated_mark, MARK, heap_segment,
+ scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
+ (scm_gc_mark_cell_conservatively): Remove function
+ scm_gc_mark_cell_conservatively and update the corresponding
+ comments and uses accordingly. Thanks to Christopher Cramer for
+ the patch. (Minor corrections by me.)
+
+2001-09-15 Gary Houston <ghouston@arglist.com>
+
+ * root.h (scm_root_state): removed the continuation_stack and
+ continuation_stack_ptr members, which have no apparent purpose.
+ (scm_continuation_stack, scm_continuation_stack_ptr): #defines
+ removed.
+
+ * root.c (root_mark), init.c (restart_stack, start_stack), gc
+ (scm_igc): remove all references to contination_stack and
+ continuation_stack_ptr, avoiding allocation of a vector and
+ useless processing during gc.
+
+2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
+
+ (TCONC_IN): Make sure that the cell word 0 is initialized last.
+
+ (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
+
+ (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
+
+ (guardian_apply, scm_get_one_zombie, scm_make_guardian,
+ mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
+
+2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * guardians.c (mark_dependencies_in_tconc,
+ whine_about_self_centered_zombies, scm_init_guardians): Register
+ the static global variable `self_centered_zombies' via
+ scm_gc_register_root, to make some cdr-ing unnecessary.
+
+2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * backtrace.c (display_backtrace_file,
+ display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM

+ Thanks to Rob Browning for the bug report.
+
+2001-09-12 Martin Baulig <martin@home-of-linux.org>
+
+ * strings.[ch] (scm_str2string): New function.
+
+2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gc.c (scm_done_free): Always subtract size from scm_mallocated
+ when computing nm, even if it's negative.
+ (scm_must_malloc): Abort on overflow of scm_mtrigger.
+ (scm_must_realloc): Likewise.
+
+2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
+
+ * numbers.c (scm_sys_check_number_conversions): new function,
+ defined if Guile is compiled in debugging mode. currently checks
+ `scm_num2ulong', should check much much more.
+
+ * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
+ unsigned, ensure that it's positive. thanks to Martin Baulig!
+
+2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * __scm.h: Added new section about compile time selectable

+
+ (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,

+
+ (scm_gc_sweep): Weak vectors don't have extra fields any more.
+
+ * weaks.c (allocate_weak_vector): New static function. It does

+ off interrupts during vector creation.
+
+ (scm_make_weak_vector, scm_make_weak_key_hash_table,

+
+ * read.c (scm_lreadr): When reading a hash token, check for a
+ user-defined hash procedure first, so that overriding the builtin
+ hash characters is possible (this was needed for implementing
+ SRFI-4's read synax `f32(...)').
+
+ * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
+ because the latter is unsigned now and breaks comparisons like
+ (n < (scm_t_signed_bits)MIN_VALUE).
+
+2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
+
+ * eval.h, eval.c (scm_call_4): New function.

+
+ The purpose of this set of changes is to regularize Guile's usage
+ of ANSI C integral types, with the following ideas in mind:
+
+ - SCM does not nesessarily have to be long.

+ The changes are incomplete and possibly buggy. Please test on
+ something exotic.

+ * backtrace.c (display_backtrace_body): since the `print_state'
+ variable is not used (instead its data field is used directly as
+ `pstate'), protect it from the hungry compiler optimizations.
+ thanks to Bill Schottstaedt for the report.
+
+2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
+ It is only defined and used if guile is compiled with
+ SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
+ let cells with a free_cell type tag be visible outside of the
+ garbage collector when in debug mode.
+
+ * gc.c (scm_debug_cell_accesses_p): Set to true as default.
+
+ (scm_assert_cell_valid): Use a local static variable to avoid
+ recursion.
+
+ (MARK): Only check for rogue cell pointers in debug mode. Use
+ scm_cellp for this purpose and place all checks for rogue pointers
+ into that function. Further, since due to conservative scanning
+ we may encounter free cells during marking, don't use the standard
+ cell type accessor macro to determine the cell type.
+
+ (scm_cellp): Check if the cell pointer actually points into a
+ card header.
+
+ (scm_init_gc): Initalize scm_tc16_allocated.
+
+ * gc.h (GCH): Renamed to SCM_GC_H.
+
+ (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
+ might be unnecessary, but I feel better this way :-)
+
+ (SCM_GC_CELL_TYPE): New macro.
+
+ (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
+ in guile, and it is unlikely that they will be applied to real
+ pairs anyway.
+
+ (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
+
+ (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
+ compiled with SCM_DEBUG_CELL_ACCESSES set to true.
+
+ (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
+ make sure that in debug mode no free cell will ever be visible
+ outside of the garbage collector.

+ in macros.h.
+
+ * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h

+ SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
+ SCM_VARIABLE_H. Even the macros that are used to inhibit
+ including a header file twice should be in the SCM_ namespace.
+
+ * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),

+ * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
+ use SCM_SET_C[AD]R for uninitialized cells.
+
+ * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
+ If the hashtable has no slots, return #f instead of '(). This
+ unifies the return value with most assoc-functions.
+
+ (scm_hash_fn_ref): Use proper type check.
+
+ (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
+ Removed references to non-existing functions from documentation.

+2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
+

+ (scm_socket, scm_socketpair): cosmetic changes.

+ (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
+ substitute. free the sockaddr structure before throwing an error.
+ (scm_init_add_buffer): procedure removed, together with its static

+ define a macro MAX_ADDR_SIZE and declare the buffer where needed.
+ (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
+ scm_sendto): use a local buffer instead of scm_addr_buffer.
+ adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
+ not size_t.
+ (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
