17 # Revision 1.51 1999/07/08 09:43:21 ftplinux
18 # Bumped release number to 0.9
20 # Revision 1.50 1999/07/07 16:17:30 ftplinux
21 # Signatures can now also be created by GnuPG; in pgp_check, also try
23 # In several messages, also mention GnuPG.
25 # Revision 1.49 1999/07/07 16:14:43 ftplinux
26 # Implemented new upload methods "copy" and "ftp" as alternatives to "ssh".
27 # Replaced "master" in many function and variable names by "target".
28 # New functions ssh_cmd, ftp_cmd, and local_cmd for more abstraction and
29 # better readable code.
31 # Revision 1.48 1998/12/08 13:09:39 ftplinux
32 # At the end of process_changes, do not remove the @other_files with the same
33 # stem if a .changes file is in that list; then there is probably another
34 # upload for a different version or another architecture.
36 # Revision 1.47 1998/05/14 14:21:44 ftplinux
37 # Bumped release number to 0.8
39 # Revision 1.46 1998/05/14 14:17:00 ftplinux
40 # When --after a successfull upload-- deleting files for the same job, check
41 # for equal revision number on files that have one. It has happened that the
42 # daemon deleted files that belonged to another job with different revision.
44 # Revision 1.45 1998/04/23 11:05:47 ftplinux
45 # Implemented $conf::chmod_on_master. If 0, new part to change mode locally in
48 # Revision 1.44 1998/04/21 08:44:44 ftplinux
49 # Don't use return value of debian_file_stem as regexp, it's a shell pattern.
51 # Revision 1.43 1998/04/21 08:22:21 ftplinux
52 # Also recogize "read-only filesystem" as error message so it triggers assuming
53 # that incoming is unwritable.
54 # Don't increment failure count after an upload try that did clear
56 # Fill in forgotten pattern for mail addr in process_commands.
58 # Revision 1.42 1998/03/31 13:27:32 ftplinux
59 # In fatal_signal, kill status daemon only if it has been started (otherwise
60 # warning about uninitialized variable).
61 # Change mode of files uploaded to master explicitly to 644 there, scp copies the
62 # permissions in the queue.
64 # Revision 1.41 1998/03/31 09:06:00 ftplinux
65 # Implemented handling of improper mail addresses in Maintainer: field.
67 # Revision 1.40 1998/03/24 13:17:33 ftplinux
68 # Added new check if incoming dir on master is writable. This check is triggered
69 # if an upload returns "permission denied" errors. If the dir is unwritable, the
70 # queue is holded (no upload tries) until it's writable again.
72 # Revision 1.39 1998/03/23 14:05:14 ftplinux
73 # Bumped release number to 0.7
75 # Revision 1.38 1998/03/23 14:03:55 ftplinux
76 # In an upload failure message, say explicitly that the job will be
77 # retried, to avoid confusion of users.
78 # $failure_file was put onĀ @keep_list only for first retry.
79 # If the daemon removes a .changes, set SGID bit on all files associated
80 # with it, so that the test for Debian files without a .changes doesn't
82 # Don't send reports for files without a .changes if the files look like
83 # a recompilation for another architecture.
84 # Also don't send such a report if the list of files with the same stem
85 # contains a .changes.
86 # Set @keep_list earlier, before PGP and non-US checks.
87 # Fix recognition of -k argument.
89 # Revision 1.37 1998/02/17 12:29:58 ftplinux
90 # Removed @conf::test_binaries used only once warning
91 # Try to kill old daemon for 20secs instead of 10
93 # Revision 1.36 1998/02/17 10:53:47 ftplinux
94 # Added test for binaries on maybe-slow NFS filesystems (@conf::test_binaries)
96 # Revision 1.35 1997/12/16 13:19:28 ftplinux
97 # Bumped release number to 0.6
99 # Revision 1.34 1997/12/09 13:51:24 ftplinux
100 # Implemented rejecting of nonus packages (new config var @nonus_packages)
102 # Revision 1.33 1997/11/25 10:40:53 ftplinux
103 # In check_alive, loop up the IP address everytime, since it can change
104 # while the daemon is running.
105 # process_changes: Check presence of .changes on master at a later
106 # point, to avoid bothering master as long as there are errors in a
108 # Don't view .orig.tar.gz files as is_debian_file, to avoid that they're
109 # picked for extracting the maintainer address in the
110 # job-without-changes processing.
111 # END statement: Fix swapped arguments to kill
112 # Program startup: Implemented -r and -k arguments.
114 # Revision 1.32 1997/11/20 15:18:47 ftplinux
115 # Bumped release number to 0.5
117 # Revision 1.31 1997/11/11 13:37:52 ftplinux
118 # Replaced <./$pattern> contruct be cleaner glob() call
119 # Avoid potentially uninitialized $_ in process_commands file read loop
120 # Implemented rm command with more than 1 arg and wildcards in rm args
122 # Revision 1.30 1997/11/06 14:09:53 ftplinux
123 # In process_commands, also recognize commands given on the same line as
124 # the Commands: keyword, not only the continuation lines.
126 # Revision 1.29 1997/11/03 15:52:20 ftplinux
127 # After reopening the log file write one line to it for dqueued-watcher.
129 # Revision 1.28 1997/10/30 15:37:23 ftplinux
130 # Removed some leftover comments in process_commands.
131 # Changed pgp_check so that it returns the address of the signator.
132 # process_commands now also logs PGP signator, since Uploader: address
133 # can be choosen freely by uploader.
135 # Revision 1.27 1997/10/30 14:05:37 ftplinux
136 # Added "command" to log string for command file uploader, to make it
137 # unique for dqueued-watcher.
139 # Revision 1.26 1997/10/30 14:01:05 ftplinux
140 # Implemented .commands files
142 # Revision 1.25 1997/10/30 13:05:29 ftplinux
143 # Removed date from status version info (too long)
145 # Revision 1.24 1997/10/30 13:04:02 ftplinux
146 # Print revision, version, and date in status data
148 # Revision 1.23 1997/10/30 12:56:01 ftplinux
149 # Implemented deletion of files that (probably) belong to an upload, but
150 # weren't listed in the .changes.
152 # Revision 1.22 1997/10/30 12:22:32 ftplinux
153 # When setting sgid bit for stray files without a .changes, check for
154 # files deleted in the meantime.
156 # Revision 1.21 1997/10/30 11:32:19 ftplinux
157 # Added quotes where filenames are used on sh command lines, in case
158 # they contain metacharacters.
159 # print_time now always print three-field times, as omitting the hour if
160 # 0 could cause confusing (hour or seconds missing?).
161 # Implemented warning mails for incomplete uploads that miss a .changes
162 # file. Maintainer address can be extracted from *.deb, *.diff.gz,
163 # *.dsc, or *.tar.gz files with help of new utility functions
164 # is_debian_file, get_maintainer, and debian_file_stem.
166 # Revision 1.20 1997/10/13 09:12:21 ftplinux
167 # On some .changes errors (missing/bad PGP signature, no files) also log the
170 # Revision 1.19 1997/09/25 11:20:42 ftplinux
171 # Bumped release number to 0.4
173 # Revision 1.18 1997/09/25 08:15:02 ftplinux
174 # In process_changes, initialize some vars to avoid warnings
175 # If first consistency checks failed, don't forget to delete .changes file
177 # Revision 1.17 1997/09/16 10:53:35 ftplinux
178 # Made logging more verbose in queued and dqueued-watcher
180 # Revision 1.16 1997/08/12 09:54:39 ftplinux
181 # Bumped release number
183 # Revision 1.15 1997/08/11 12:49:09 ftplinux
184 # Implemented logfile rotating
186 # Revision 1.14 1997/08/11 11:35:05 ftplinux
187 # Revised startup scheme so it works with the socket-based ssh-agent, too.
188 # That watches whether its child still exists, so the go-to-background fork must be done before the ssh-agent.
190 # Revision 1.13 1997/08/11 08:48:31 ftplinux
191 # Aaarg... forgot the alarm(0)'s
193 # Revision 1.12 1997/08/07 09:25:22 ftplinux
194 # Added timeout for remote operations
196 # Revision 1.11 1997/07/28 13:20:38 ftplinux
197 # Added release numner to startup message
199 # Revision 1.10 1997/07/28 11:23:39 ftplinux
200 # $main::statusd_pid not necessarily defined in status daemon -- rewrite check
201 # whether to delete pid file in signal handler.
203 # Revision 1.9 1997/07/28 08:12:16 ftplinux
204 # Again revised SIGCHLD handling.
205 # Set $SHELL to /bin/sh explicitly before starting ssh-agent.
206 # Again raise ping timeout.
208 # Revision 1.8 1997/07/25 10:23:03 ftplinux
209 # Made SIGCHLD handling more portable between perl versions
211 # Revision 1.7 1997/07/09 10:15:16 ftplinux
212 # Change RCS Header: to Id:
214 # Revision 1.6 1997/07/09 10:13:53 ftplinux
215 # Alternative implementation of status file as plain file (not FIFO), because
216 # standard wu-ftpd doesn't allow retrieval of non-regular files. New config
217 # option $statusdelay for this.
219 # Revision 1.5 1997/07/09 09:21:22 ftplinux
220 # Little revisions to signal handling; status daemon should ignore SIGPIPE,
221 # in case someone closes the FIFO before completely reading it; in fatal_signal,
222 # only the main daemon should remove the pid file.
224 # Revision 1.4 1997/07/08 11:31:51 ftplinux
225 # Print messages of ssh call in is_on_master to debug log.
226 # In ssh call to remove bad files on master, the split() doesn't work
227 # anymore, now that I use -o'xxx y'. Use string interpolation and let
228 # the shell parse the stuff.
230 # Revision 1.3 1997/07/07 09:29:30 ftplinux
231 # Call check_alive also if master hasn't been pinged for 8 hours.
233 # Revision 1.2 1997/07/03 13:06:49 ftplinux
234 # Little last changes before beta release
