1 2007-11-25 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/.cvsignore: Update to match current gnulib.
4 * m4/.cvsignore: Likewise.
6 * gzip.c (handled_sig): Move out of install_signal_handlers, and
7 move previous to all uses of SIGPIPE, to fix a bug encountered when
8 porting to mingw32. Reported by Robert Millan in
9 <https://lists.gnu.org/archive/html/bug-gzip/2007-11/msg00007.html>.
11 2007-10-04 Paul Eggert <eggert@cs.ucla.edu>
13 * doc/gzip.texi: Adjust to new fdl.texi format, in gnulib.
15 * Makefile.am (gzip.doc.gz, check-local): Depend on $(bin_PROGRAMS).
16 (gzip.doc.gz): Use our gzip, not the system-installed one.
17 Problem reported by Chris Staub in
18 <https://lists.gnu.org/archive/html/bug-gzip/2007-10/msg00000.html>.
20 2007-07-03 Paul Eggert <eggert@cs.ucla.edu>
22 * COPYING: Update to GPLv3. All uses changed.
24 2007-06-13 Paul Eggert <eggert@cs.ucla.edu>
26 * zless.1: Fix some troff typos mentioned in the latest Debian patch.
27 Also, give a workaround for the pipe problem.
29 * gzip.c (copy_stat): Adjust to gnulib's renaming of futimens to
30 gl_futimens.
32 2007-06-04 Paul Eggert <eggert@cs.ucla.edu>
34 * gzip.c (get_method): Fix typo: "a a" -> "a" in diagnostic. Reported
35 by Justin Pryzby in Debian bug 426965 <https://bugs.debian.org/426965>.
37 2007-05-07 Paul Eggert <eggert@cs.ucla.edu>
39 * NEWS: 'gzip -f foo.gz' now works instead of complaining.
40 * gzip.c (make_ofname): Implement this.
41 Problem reported by Sven Hartrumpf in
42 <https://lists.gnu.org/archive/html/bug-gzip/2007-05/msg00003.html>.
44 * NEWS, gzip.1: Document that case is ignored when looking at file name
45 extensions.
46 * doc/gzip.texi (Overview): Likewise.
48 2007-05-04 Paul Eggert <eggert@cs.ucla.edu>
50 * Makefile.am (.in): Substitute @bindir@, not BINDIR, for
51 consistency with other substitutions.
52 (check-local): Use --__bindir . rather than setting GZIP_BINDIR=.,
53 to allay security concerns voiced by Joerg Lehners in
54 <https://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00003.html>.
55 * gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zegrep.in, zfgrep.in:
56 * zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
57 Support --__bindir rather than GZIP_BINDIR.
59 * gunzip.in, zcat.in, zcmp.in: Support --help and --version
60 directly, to avoid some confusion in help and version output.
61 Problem reported by Eric Blake in
62 <https://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00006.html>.
64 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
66 * m4/shell.m4 (AC_PROG_SHELL): Check for old-fashioned shells that
67 don't allow "(" in front of case labels. Problem reported by midair
68 in <https://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00004.html>.
69 Also, check for buggy shells that require ";;" before "esac".
71 2007-04-13 Paul Eggert <eggert@cs.ucla.edu>
73 * NEWS: Version 1.3.12 released.
74 * configure.ac (AC_INIT): Likewise.
76 * README: Update year in copyright notice.
77 * m4/shell.m4: Add copyright notice.
79 * bootstrap (gnulib_tool_option_extras): Put this back; it was
80 inadvertently omitted from gnulib.
81 (gnulib_tool_option): Use it.
82 * .cvsignore: Add *._bootmp*.
83 * lib/.cvsignore: Add stdlib.h, stdlib_.h, time.h, time_.h, unistd.h.
84 Remove alloca.c, alloca.h, alloca_.h, exit.h, getdelim.c, getdelim.h,
85 getline.c, getline.h, malloc.c, mbchar.c, mbchar.h, mbuiter.h, memchr.c,
86 regcomp.c, regex.c, regex.h, regex_internal.c, regex_internal.h,
87 regexec.c, rpmatch.c, stdint.h, stdint_.h, strcase.h, strcasecmp.c,
88 strncasecmp.c, strnlen1.c, strnlen1.h, timespec.h, wcwidth.h.
89 * m4/.cvsignore: Add stdlib_h.m4, time_h.m4.
90 Remove alloca.m4, codeset.m4, getdelim.m4, getline.m4,
91 longlong.m4, mbchar.m4, mbiter.m4, mbrtowc.m4, memchr.m4, regex.m4,
92 rpmatch.m4, ssize_t.m4, stdint.m4 strcase.m4, timespec.m4, ulonglong.m4,
93 wchar_t.m4, wcwidth.m4, wint_t.m4.
95 2007-03-29 Paul Eggert <eggert@cs.ucla.edu> (tiny change)
97 * znew.in (tmp): Use $TMPDIR as temp directory, if given.
98 Suggested by Juan Manuel Guerrero.
100 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
102 * README-hacking: New file, renamed from README-cvs.
103 * README-cvs: Remove.
104 * bootstrap: Sync from today's gnulib.
105 * bootstrap.conf (gnulib_modules): Add 'time'.
106 * gzip.c: Don't include timespec.h; 'time' fixes time.h for that.
107 * zip.c: Likewise.
108 * gzip.c: Don't include time.h or sys/time.h; gzip.h now includes
109 time.h, which is now enough.
110 * gzip.h: Include <time.h>.
112 2007-03-14 Paul Eggert <eggert@cs.ucla.edu>
114 * README (WARNING): Reword to avoid mention of no-longer-existing
115 section in INSTALL file. Problem reported by Paul Townsend in
116 <https://lists.gnu.org/archive/html/bug-gzip/2007-03/msg00000.html>.
118 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
120 * gzip.c (foreground): Initialize to zero. This doesn't fix a bug
121 since C guarantees it's zero, but it's more consistent with the
122 rest of the code. Problem reported by Mark Adler.
124 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
126 * zdiff.in: Don't use '((' in a shell script, as it's not portable
127 to some ksh implementations, e.g., Solaris 10 ksh M-11/16/88i.
128 Problem reported by Nelson H. F. Beebe in
129 <https://lists.gnu.org/archive/html/bug-gzip/2007-02/msg00005.html>.
131 2007-02-05 Paul Eggert <eggert@cs.ucla.edu>
133 * NEWS: Version 1.3.11 released.
134 * configure.ac (AC_INIT): Likewise.
136 * doc/gzip.texi: Convert Texinfo format into a more modern style.
137 Put in current output samples.
139 * .cvsignore: Add *.gz, gunzip, zcat, zcmp, zegrep, zfgrep.
140 * lib/.cvsignore: Add sys_time_.h, unistd_.h.
141 * m4/.cvsignore: Add gnulib-common.m4, sys_time_h.m4.
143 * gunzip.in, zcat.in, zcmp.in, zegrep.in, zfgrep.in: New files.
144 * Makefile.am (EXTRA_DIST): Add them.
145 (bin_SCRIPTS, MOSTLYCLEANFILES): Add gunzip, zcat, zcmp, zdgrep, zfgrep.
146 (.in): Use GZIP_BINDIR as the location of gzip binaries, if it is set.
147 (check-local): Use GZIP_BINDIR.
148 (install-exec-hook, remove-installed-links): Make 'uncompress' an
149 alias for gunzip.
150 * gzexe.1: At least one arg is required. Don't give cat as an
151 example, since gzexe refuses to compress cat due to a bootstrapping
152 issue. List more utilities in this category.
153 * gzexe.in, zdiff.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
154 Report our name in usage.
155 * gzexe.in: Don't compress bash. Don't use rmdir, so it's
156 OK to compress rmdir.
157 * gzip.c: Now requires that you compile with -DGNU_STANDARD=0 to
158 get non GNU-standard behavior. We now build with GNU-standard
159 behavior by default, so that programs do not depend on the names
160 of their executables.
161 * zdiff.in: Don't depend on the name of the executable, as per
162 GNU standard. Instead, rely on an internal --__cmp option.
163 Support ' in options. Check for failures in subsidiary gzip
164 invocations.
165 * zgrep.1: Clarify compression issues.
166 * zgrep.in: Don't assume POSIX-style case syntax. Remove unused var
167 have_optarg.
168 * zless.1: zless sets LESSMETACHARS now.
170 2007-01-10 Paul Eggert <eggert@cs.ucla.edu>
172 * m4/shell.m4 (AC_PROG_SHELL): Test that $(...) works.
173 Problem reported for SGI IRIX 6 by Nelson H. F. Beebe in
174 <https://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00007.html>.
176 2007-01-04 Paul Eggert <eggert@cs.ucla.edu>
178 * zdiff.in (cmp0): New var.
179 Rewrite test for /dev/fd/3 to detect bugs in Solaris 8
180 /bin/bash 2.03. Problem reported by Nelson H. F. Beebe in
181 <https://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00001.html>.
182 Avoid "for file; do", which doesn't work with Solaris 8 /bin/sh.
184 2007-01-03 Paul Eggert <eggert@cs.ucla.edu>
186 * zdiff.in: Test /dev//fd/3, not /dev/fd/3, to work around a problem
187 with Tru64 4.0F ksh M-11/16/88f reported by Thomas Koutcher in
188 <https://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00000.html>.
190 2006-12-30 Paul Eggert <eggert@cs.ucla.edu>
192 * NEWS: Version 1.3.10 released.
193 * configure.ac (AC_INIT): Likewise.
195 * Makefile.am (check-local): Don't assume $(srcdir) is '.'.
196 (MAINTAINERCLEANFILES): Move gzip.doc.gz from here ...
197 (MOSTLYCLEANFILES): ... to here.
199 2006-12-29 Paul Eggert <eggert@cs.ucla.edu>
201 * zless.in: Work around a bug in less 394 and earlier; it
202 mishandles $%=~ in file names. Problem reported by
203 Sami Liedes in <https://bugs.debian.org/383358>.
205 * doc/gzip.texi: Swap order of dircategory entries, to pacify
206 Debian install-info 1.10.28. This should fix
207 <https://bugs.debian.org/404048>.
209 * zgrep.in (version): Fix bug: $grep wasn't evaluated.
211 * zgrep.in: Rewrite to make the option processing more
212 compatible with GNU and POSIX grep. Assume POSIX shell
213 for more stuff, since we're already assuming that.
214 * Makefile.am (check-local): Check zgrep -iV.
216 2006-12-26 Paul Eggert <eggert@cs.ucla.edu>
218 Fix Debian bug 367673 <https://bugs.debian.org/367673> plus several
219 other bugs discovered in the neighborhood.
220 * NEWS: gzip -q now exits with status 2 (not 1) on SIGPIPE.
221 zgrep has many bugs fixed with argument handling, special characters,
222 and exit status.
223 * gzip.c (abort_gzip_signal): Implement gzip -q change.
224 * zgrep.in: Implement zgrep change.
226 2006-12-23 Paul Eggert <eggert@cs.ucla.edu>
228 * NEWS: Fix bug reported by Martin Mares in
229 <https://bugs.debian.org/177942>.
230 * gzip.c (treat_stdin): Remove NO_STDIN_FSTAT and NO_PIPE_TIMESTAMP
231 stuff. It didn't work (led to syntax errors) and was confusing.
232 Report an error if stdin cannot be statted even if !list && no_time.
233 Get stdin's size if it is regular.
234 (treat_file): Do not report an error with setuid, setgid,
235 sticky, or non-regular, non-directory files if to_stdout.
236 Allow 'force' to override the caution about sticky files.
237 Use the same form for timestamps that treat_stdin uses.
239 * zdiff.in: Fix typo that broke most usages. Problem reported by
240 Jari Aalto in <https://bugs.debian.org/404114>. While we're at it,
241 fix a bunch of other problems. Handle "-" better. Send
242 diagnostics to stderr, not stdout. Use expr rather than echo |
243 sed, to handle special characters better. Report a diagnostic in
244 the 1-arg case, if the argument doesn't end in .gz or the like,
245 rather than having incomprehensible behavior. Do not require that
246 the inputs be regular files. Avoid creating a temporary entirely,
247 if /dev/fd works. If not, then resist denial-of-service attacks
248 better, by using mktemp.
249 * NEWS: Document this.
250 * Makefile.am (gzip.doc.gz): New rule.
251 (check-local): Depend on it, and test zdiff for Debian bug 404114.
253 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
255 * zdiff.1: Mention that these programs currently understand only
256 formats that gzip does. Problem reported by Jari Aalto in
257 <https://bugs.debian.org/404099>.
259 2006-12-20 Paul Eggert <eggert@cs.ucla.edu>
261 * inflate.c (huft_build): Fix regression that caused gzip to
262 refuse to uncompress null input (all zero length codes). Problem
263 reported by Yiorgos Adamopoulos. This regression was caused by
264 the security patch installed 2006-11-20, which in turn came from
265 Debian, which in turn apparently came from Thomas Biege of SuSe.
267 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
269 * NEWS, configure.ac (AC_INIT):
270 Version 1.3.9 released.
272 * Makefile.am (MOSTLYCLEANFILES): Add _match.i.
273 * configure.ac (for an assembler syntax supported by this package):
274 Remove _match.i.
276 * bootstrap (gnulib_tool_options_extras): New var.
277 (gnulib_tool_options): Use it.
278 * bootstrap.conf (gnulib_tool_options_extras): Avoid getline and
279 rpmatch. gzip doesn't need them, since it doesn't ENABLE_NLS.
281 2006-12-13 Bruno Haible <bruno@clisp.org>
283 * configure.ac: Use $CPPFLAGS everywhere $CPP is used, and use
284 $CPPFLAGS $CFLAGS everywhere $CC is used.
285 * lib/Makefile.am (match.$(OBJEXT)): Likewise.
286 * configure.ac: Test the exit code of the $CPP and $ASCPPPOST commands
287 separately.
289 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
291 * configure.ac (ASCPPPOST): Simplify to use just 'sed'.
292 * lib/Makefile.am (match.$(OBJEXT)): Check for CPP failure.
294 2006-12-11 Bruno Haible <bruno@clisp.org>
296 Cross-compilation support.
297 * configure.ac (ASCPP): Remove substituted variable.
298 (ASCPPPOST, ASCPPFLAGS): New substituted variables.
299 * lib/Makefile.am (ASCPP, LN_S): Remove unnecessary macro definitions.
300 (match.$(OBJEXT)): Use CPP, ASCPPFLAGS, ASCPPPOST instead of ASCPP.
301 * configure.ac: Add test for chown function.
302 * gzip.c (treat_file) [!HAVE_CHOWN]: Don't call chown.
303 * gzip.c: Include "timespec.h". This doesn't fix any bugs, but
304 it is clearer.
306 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
308 The SSIZE_MAX fix didn't work on NSK, so fix it in a more-reliable
309 (albeit more-complicated) way. Problem reported by Matthew Woehlke.
310 * gzip.h (read_buffer): New decl.
311 * unlzw.c (unlzw): Use read_buffer rather than read.
312 * zip.c (file_read): Likewise.
313 * util.c (copy, fill_inbuf): Likewise.
314 (read_buffer, write_buffer): New functions.
315 (write_buf): Use write_buffer rather than write.
317 Undo the previous SSIZE_MAX-related change; it didn't work.
318 * gzip.c: Include <limits.h>.
319 * util.c: Likewise.
320 * gzip.h: Don't include <limits.h>.
321 (INBUFSIZ): Don't worry about SSIZE_MAX here.
323 2006-12-08 Paul Eggert <eggert@cs.ucla.edu>
325 * NEWS, configure.ac (AC_INIT):
326 Version 1.3.8 released.
328 * gzexe.in (mktemp_status): New var, used to see whether
329 mktemp is a known command. Use this instead of confounding
330 mktemp's existence with its success.
332 * zdiff.in: Remove first line containing ":". This follows
333 up on the SEDCMD fix of 2006-12-01.
334 * zforce.in: Likewise.
335 * zgrep.in: Likewise.
336 * zless.in: Likewise.
337 * zmore.in: Likewise.
338 * znew.in: Likewise.
340 Fix problems in porting to NSK reported by Matthew Woehlke in
341 <https://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00025.html> and
342 <https://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00027.html>.
343 * gzip.h: Include <limits.h>, for SSIZE_MAX.
344 (INBUFSIZE): Don't make it any larger than SSIZE_MAX.
345 Problem reported by Matthew Woehlke in
346 <https://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
347 * gzip.c: Don't include <limits.h>, as gzip.h now does this.
348 * util.c: Likewise.
349 * gzip.c (main): Set exiting_signal before installing signal handlers.
350 (install_signal_handlers): Don't set exiting_signal here. This
351 fixes a C99ism.
352 * zip.c: Include timespec.h, for time_stamp type.
354 2006-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
356 * gzexe.in: Work around FreeBSD shell trap bug.
357 * gzip.1: Fix typo.
358 * doc/gzip.texi: Likewise.
360 2006-12-08 Paul Eggert <eggert@cs.ucla.edu>
362 * .cvsignore: Add .deps, gzexe, gzip, zdiff, zforce, zgrep,
363 zless, zmore, znew.
364 * doc/.cvsignore: Add Makefile.
365 * lib/.cvsignore: Add .deps, Makefile, alloca.h, config.h, fcntl.h,
366 stamp-h1, stdint.h, sys.
368 * configure.ac (for assembler): Set ASFLAGS_config to
369 -Wa,--noexecstack if this seems advisable on this platform.
370 Problem reported by Mike Frysinger in
371 <https://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00018.html>.
372 * lib/Makefile.am (match.$(OBJEXT)): Use ASFLAGS_config.
374 2006-12-07 Paul Eggert <eggert@cs.ucla.edu>
376 * Makefile.am (install-exec-hook): Fix bug when installing
377 symbolic links as aliases. Problem reported by Mike Frysinger.
379 * deflate.c (deflate_fast, deflate): Avoid core dump. Problem
380 originally reported by Jochen Friedrich and trivial patch supplied
381 by Anthony Towns; see <https://bugs.debian.org/184057>.
383 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
385 * NEWS, configure.ac (AC_INIT):
386 Version 1.3.7 released.
388 2006-12-06 Bruno Haible <bruno@clisp.org> (tiny change)
389 and Paul Eggert <eggert@cs.ucla.edu>
391 Fix build failure on case-insensitive file systems.
392 * configure.ac: Use match_.s instead of _match.s.
393 * Makefile.am (MOSTLYCLEANFILES): Likewise.
394 * lib/Makefile.am (match.$(OBJEXT)): Likewise.
395 (MOSTLYCLEANFILES): Likewise.
397 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
399 * NEWS: Document the fixes below.
400 * configure.ac (AC_CHECK_FUNCS_ONCE): Add siginterrupt.
401 * gzip.c (lstat) [!defined(HAVE_LSTAT) && !defined(lstat)]: Remove.
402 (SA_NOCLDSTOP, sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
403 New macros.
404 (siginterrupt) [!defined SA_NOCLDSTOP && ! HAVE_SIGINTERRUPT]:
405 New macro.
406 (HAVE_WORKING_O_NOFOLLOW): Define to 0 if not defined.
407 (caught_signals, exiting_signal, remove_ofname_fd): New vars.
408 (remove_ofname): Remove; all uses changed to remove_ofname_fd.
409 (same_file, name_too_long): Remove.
410 (install_signal_handlers): New function. It prefers sigaction,
411 which is more reliable in the presence of race conditions.
412 Catch SIGXCPU and SIGXFSZ, too.
413 (main): Use it instead of installing them by hand.
414 (treat_file): Check for read error when closing ifd.
415 (treat_file, create_outfile, remove_output_file):
416 Avoid race conditions with signals.
417 (create_outfile, check_ofname): Remove most of the gorp about
418 working around ENAMETOOLONG deficiencies. It's obsolete now, and
419 anyway it had race conditions. Just rely on O_EXCL and
420 ENAMETOOLONG. The worst that can happen is that a file name will
421 be silently truncated on an obsolete machine, but no data will be lost.
422 (open_and_stat): Use HAVE_WORKING_O_NOFOLLOW rather than O_NOFOLLOW
423 to work around some O_NOFOLLOW bugs. Otherwise, fall back on
424 lstat only if lstat is available, as symlinks don't exist otherwise.
425 (open_input_file): Use O_NONBLOCK and O_NOCTTY too, to avoid
426 hanging gzip on special files.
427 (abort_gzip_signal): If sigaction is not available, ignore
428 signals. If we get the exiting signal, exit with ERROR status
429 rather than raising a signal.
430 * tailor.h (NO_ST_INO): Remove; no longer used now that same_file
431 is gone.
433 2006-12-05 Paul Eggert <eggert@cs.ucla.edu>
435 Port to Tandem NSK/OSS, which lacks fchdir. Problem reported by
436 Matthew Woehlke in
437 <https://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
438 * bootstrap.conf (gnulib_modules): Remove openat, as it pulls in
439 fchdir.
440 * configure.ac: Check for fdopendir.
441 * gzip.c: Don't include openat.h; no longer needed.
442 (treat_dir) [!HAVE_FDOPENDIR]: Fall back on the old opendir method
443 since fdopendir is not available.
445 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
447 * NEWS: Describe the following change briefly.
448 * bootstrap.conf (gnulib_modules): Remove stat-macros; no longer
449 needed.
450 * gzip.c: Don't include stat-macros.h; no longer needed.
451 (treat_file): Refuse to compress files that are setuid, or setgid,
452 as this can in theory lead to security holes. Also, refuse to
453 compress files with the sticky bit set, on general principle.
454 (copy_stat): Don't copy the setuid, setgid, or sticky bits,
455 as (given the above change) they'll always be zero here.
456 Invoke chown before chmod, to close a race condition.
458 * .cvsignore: Add *.doc, build-aux.
459 * doc/.cvignore: New file.
460 * lib/.cvsignore: New file.
461 * m4/.cvsignore: New file.
463 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
465 * doc/gzip.texi (Overview): Mention limits of gzip format's
466 timestamps. Also, gzip doesn't always preserve timestamps.
468 * gzip.c (abort_gzip_signal): Don't call abort () as a "safeguard",
469 since it actually causes a core dump. Problem reported by
470 Jakub Bogusz.
472 * NEWS: Describe gzexe changes noted below.
473 * Makefile.am (.in): Don't bother with SEDCMD. This stuff isn't needed
474 any more (the hosts it caters to are long extinct), and was
475 questionable anyway since the code assumes the skip= line was line 2.
476 * configure.ac (AC_SYS_INTERPRETER, SEDCMD): Remove; no longer needed.
478 * gzexe.in: Sweep the code and fix some bugs.
479 My, what sharp teeth you have, gzexe!
480 The straw that broke this camel's back was Matthew Burgess's bug report
481 <https://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00012.html>.
483 (IFS): Set it to the standard value, both here and in the
484 script gzexe generates.
485 Check for missing operand after parsing options, not before.
486 This fixes the case for "cpexe --".
487 Check for tail -n problem separately in gzexe and in the executable
488 it generates, in case it's a different 'tail'.
489 (trap): Remove $tmp only if $tmp is not the empty string.
490 Preserve exit status.
491 Don't use the nonstandard (and rarely available) "cpmod" utility.
492 Don't use "set -C"; it's no longer useful and it breaks things
493 in some cases.
494 (main loop): Handle file names beginning with "-".
495 Exit with status of failing program, not with 1.
496 Fix some bugs in printing diagnostics, and in quoting.
497 Require the skip= line to have at least one digit.
498 Use test -u and test -g rather than using the (less-reliable) ls.
499 Refuse to compress more programs, e.g., sh.
500 Use mktemp rather than tempfile. Build a copy of
501 the compressed or uncompressed executable in the same
502 directory as the executable, as that's less likely to go wrong
503 if disk space is low. Have the executable exit with status 127,
504 not 1, if the decompression process fails; this is more compatible
505 with meta-programs like nohup. Have the executable
506 uncompress to a temp file with the same basename as the executable;
507 this is more likely to go right. Fix a race condition where the
508 executable temporarily did not exist (in either old or new forms).
509 Check for race conditions better when mv fails. Do not attempt
510 to use cp to do the real work, only to copy permissions to a temp
511 file, since we don't want to trash running executables.
513 2006-11-26 Paul Eggert <eggert@cs.ucla.edu>
515 * inflate.c (inflate_dynamic, inflate): Don't send output to
516 stderr unless DEBUG is defined and 'verbose'. Problem reported by
517 Santiago Vila.
519 * zgrep.in: If the file name contains newline, &, \, or |, escape
520 the character so that 'sed' doesn't mishandle it as a replacement.
521 Problem reported by Bdale Garbee.
523 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
525 * gzip.1 (OPTIONS): ouput -> output. Problem reported by Matt
526 Taggart.
527 * vms/gzip.hlp: Likewise.
529 * Makefile.am (FILES_TO_CHECK): New macro.
530 (check-local): Check only the files in FILES_TO_CHECK, since some
531 files under the working directory might be mutating as the test is
532 run, e.g., with "make check >log". Problem reported by Jim
533 Meyering.
535 2006-11-20 Paul Eggert <eggert@cs.ucla.edu>
537 * NEWS, configure.ac (AC_INIT):
538 Version 1.3.6 released.
540 * NEWS: Describe 1.3.6's changes.

545 * TODO: Add new tasks to remove porting cruft and
546 all those buggy scripts.
548 * configure.ac: Renamed from configure.in.
549 (AC_PREREQ): Bump to 2.60.
550 (AC_INIT): Bump version to 1.3.6.
551 (AC_CONFIG_AUX_DIR): New.
552 (AC_CONFIG_HEADERS): Move config.h to lib.

558 (gl_EARLY, gl_INIT): New.
559 match.c was moved to lib/match.c.
560 (AC_CHECK_HEADERS_ONCE): Replace AC_CHECK_HEADERS. Don't check
561 for sys/utime.h or utime.h.
562 (AC_CHECK_FUNCS_ONCE): Replace AC_CHECK_FUNCS. Check for fchmod
563 and fchown, not utime.
564 (AC_REPLACE_FUNCS): Remove; rpmatch is now done by gnulib.
565 (AC_CONFIG_FILES): Add doc/Makefile, lib/Makefile.
567 * bits.c: Use the more-usual form for copyright notices in source code.
568 * deflate.c: Likewise.
569 * gzip.c: Likewise.
570 * gzip.h: Likewise.
571 * inflate.c: Likewise.
572 * lzw.h: Likewise.
573 * revision.h: Likewise.
574 * tailor.h: Likewise.
575 * trees.c: Likewise.
576 * unpack.c: Likewise.
577 * unzip.c: Likewise.
578 * util.c: Likewise.
579 * crypt.c (dummy): Add decl so that pedantic compilers won't
580 complain about an empty file.
581 * gzip.c (license_msg): Use more-modern wording.
582 Include fcntl-safer.h, openat.h, stat-macros.h, stat-time.h.
583 Simply include <dirent.h> if !NO_DIR, removing a rats-nest of
584 #ifdefs.
585 Simply include <utimens.h> if !defined NO_UTIME, removing a
586 another rats-nest of #ifdefs.
587 (DIR_OPT, TIME_OPT): Remove.
588 (_D_EXACT_NAMLEN): Renamed from NAMLEN. All uses changed.
589 (S_ISDIR, S_ISREG, O_BINARY, O_CREAT, O_EXCL, S_IRUSR, S_IWUSR):
590 Remove; gnulib now does this.
591 (RETSIGTYPE): Remove; Autoconf does this.
592 (program_name): Renamed from progname, for compatibility with gnulib.
593 All uses changed.
594 (time_stamp): Now struct timespec, not time_t. All uses changd.
595 (remove_oftime): Now volatile.
596 (reset_times): Remove; now done by futimens.
597 (usage): Remove.
598 (try_help): New function.
599 (help, license): Don't output date as part of version.
600 A version number suffices.
601 (help): Redo help message to match style of coreutils etc.
602 (version): Don't bother printing compile-time configuration info
603 like STDC_HEADERS.
604 (main): Don't assume strlen (argv[0]) < INT_MAX (!).
605 On usage errors, suggest --help without outputting all the help.
606 (main, do_list): Remove unnecessary casts.
607 (treat_stdin, treat_file, get_method, copy_stat):
608 Support sub-second timestamp resolution.
609 (treat_file, copy_istat): Close some race conditions if files are
610 renamed as we read or write them.
611 (treat_file): Do not attempt to reset the access times of
612 directories that we read.
613 (open_and_stat, open_input_file): New functions.
614 (do_stat, get_istat): Remove; most of the contents went to these new
615 functions.
616 (make_ofname): Don't use WARN, as it affects exit status.
617 (get_method): When the original file name was truncated,
618 restore from its base name, not from its full name.
619 (do_list): Avoid undefined behavior with out-of-range timestamps.
620 ctime, for example, cannot be invoked on arbitrary timestamps safely,
621 since it might overrun an internal buffer. Do not assume that
622 localtime succeeds.
623 (copy_stat): Do not remove input file; that's now the caller's
624 responsibility. This avoids a problem if there is a write error
625 when the caller closes the output file.
626 (treat_dir): New arg FD, to avoid a race condition. All uses changed.
627 (remove_output_file): New function.
628 (abort_gzip): Use it.
629 (abort_gzip_signal): New function, which is async-signal-safe.
630 Exit with the signal that we got.
631 * gzip.h (program_name, time_stamp, abort_gzip): Adjust decls to
632 match gzip.c changes.
633 * inflate.c (huft_build): Return 2 if null input.
634 * tailor.h (HAVE_UTIME): Do not define; gnulib does this now.
635 (OPEN): Use open_safer, not plain open.
636 * unlzh.c (NPT): Set to 1<<TBIT, not to the maximum of NT and NP.
637 (make_table): Report an error if 1<<tablebits < nextcode.
638 (read_pt_len): Report an error if 16 < c.
639 * unpack.c (read_tree): Report an error if the tree has too many
640 leaves while reading it. Fix off-by-one error in final check.
641 * util.c: Include <xalloc.h>, for xalloc_die decl.
642 (gzip_base_name): Renamed from base_name, so we don't collide
643 with gnulib. All uses changed.
644 (add_envopt): Use xstrdup instead of xmalloc+strcpy.
645 Use xcalloc rather than calloc + check.
646 (gzip_error): Renamed from error, so we don't collide with gnulib.
647 All uses changed.
648 (xalloc_die): New function.
649 (xmalloc): Remove; no longer needed.
650 * zip.c (zip): Watch for timestamp overflow; the old code
651 mishandled negative timestamps.
653 * gzexe.in: Add support for --help, --version, --.
654 Don't call basename or sed if we can avoid it.
655 * zdiff.in: Likewise.
656 * zforce.in: Likewise.
657 * zgrep.in: Likewise.
658 * zless.in: Likewise.
659 * zmore.in: Likewise.
660 * znew.in: Likewise.
661 * zdiff.in: Protect against file names beginning with "-".
662 * zmore.in: Likewise.
663 * zgrep.in: Use printf rather than echo, to avoid problems with
664 leading "-" and backslash. Return status of subsidiary grep.
665 * zless.in: Add copyright notice.
667 * zless.1: We now pass "--" to LESSOPEN.
668 (BUGS): Mention that input file arguments are required.
669 Add copyright notice.
671 * COPYING: Update to current version.
673 * Makefile.am (SUBDIRS): New macro.
674 (AUTOMAKE_OPTIONS): Remove; now done in configure.ac.
675 (M4DIR, ACINCLUDE_INPUTS): Remove.
676 (EXTRA_DIST): Remove getopt.h.
677 (gzip_SOURCES): Remove getopt.c, getopt1.c, yesno.c.
678 (gzip_LDADD): Change from @LIBOBJS@ to lib/libgzip.a.

680 (match.$(OBJEXT)): Move to subdirectory makefiles.
681 (.in): Substitute @VERSION@, too.
682 (check-local): New rule.
683 (MOSTLYCLEANFILES): Add _match.S.
685 * doc/gzip.texi: Renamed from gzip.texi. Change to GNU FDL
686 without invariant sections or cover texts. Don't put
687 version number or date into sample gzip -h output.
688 * lib/match.c: Renamed from match.c. Add ia64 version
689 written by Sverre Jarp (HP Labs).
691 * INSTALL: Remove from CVS; now created automatically by
692 the bootstrap script.
693 * Makefile.in: Likewise.
694 * aclocal.m4: Likewise.
695 * config.h.in: Likewise.
696 * configure: Likewise.

699 * getopt.c: Likewise.
700 * getopt.h: Likewise.
701 * getopt1.c: Likewise.
702 * gzip.doc: Likewise.
703 * gzip.info: Likewise.
704 * install-sh: Likewise.
705 * mdate-sh: Likewise.
706 * missing: Likewise.
707 * mkinstalldirs: Likewise.
708 * rpmatch.c: Likewise.
709 * stamp-vti: Likewise.
710 * texinfo.tex: Likewise.
711 * version.texi: Likewise.
712 * yesno.c: Likewise.
714 2002-09-30 Paul Eggert <eggert@twinsun.com>
716 * NEWS, README, revision.h, configure.in (AM_INIT_AUTOMAKE):
717 Revision 1.3.5, dated today.
719 * util.c (fprint_off): Fix bug in printing values greater than
720 10 * 2**32 bytes. Bug reported by Bryan Andersen.
722 * Makefile.am (match.$(OBJEXT)): Use .S as extension for $(ASCPP),
723 to keep gcc happy.
724 * configure.in: Likewise.
725 Upgrade assembly-language checking for Autoconf 2.54, using cache vars.
726 (AC_PROG_CPP, AC_OBJEXT): Add.
728 * match.c: Accept __i386 and __i386__ as synonyms for i386.
729 Bug reported by "fork __" <bouloumag@hotmail.com>.
731 2002-09-29 Paul Eggert <eggert@twinsun.com>
733 * gzip.texi (Overview): Suggest how to use gunzip on zip files.
735 * zless.1, zless.in: Use LESSOPEN, not PAGER.
736 Suggested by <antos@MAST.queensu.ca>.
738 2002-09-28 Paul Eggert <eggert@twinsun.com>
740 * zforce.in: Use shell pattern matching instead of 'expr', which
741 mishandles names like "+". Remove old check for 14-byte file
742 names on hosts with broken "mv" implementations, as such systems
743 aren't in use any more and it's better nowadays to support file
744 names longer than 14 bytes. Rely on "mv"'s error-reporting.
745 This fixes a portability bug reported by Ralf Neubauer, along
746 with some other bugs.
748 Remove dangling output symlinks properly.
749 Bug reported by Kalle Olavi Niemitalo.
750 * gzip.c (lstat): New macro, for platforms lacking lstat.
751 (do_stat): Use it.
752 (name_too_long, check_ofname): Use lstat instead of stat.
754 2002-09-27 Paul Eggert <eggert@twinsun.com>
756 * zforce.in: Use "gzip -lv", not "gzip -v". Patch by Ralf
757 Neubauer.
759 * configure.in (ASCPP): Don't use test -a, as POSIX says it's
760 not portable.
761 * znew.in: Likewise.
762 * zmore.in: Likewise. Similarly, don't use test -o, or test -t
763 with no operand.
765 * gzexe.in (PATH): Set to same as other programs.
766 Don't assume "tail +22" works; POSIX removed this.
767 Check against compressing "tail".
768 Check against "skip=" line with no integer.
769 * zgrep.in: Exit with status 2 if trouble, for consistency with grep.
771 * gzip.c (main): Avoid core dump in diagnostic message if
772 incorrect suffix is given.
774 2002-09-26 Paul Eggert <eggert@twinsun.com>
776 * zdiff.in: Use "trap -" instead of "trap". Patch by Nicolas Boullis.
777 Use names, not numbers, for signals. Patch by Andrew Stribblehill.
779 * NEWS, README, revision.h, configure.in (AM_INIT_AUTOMAKE):
780 Revision 1.3.4, dated today.
782 * README-alpha: Upgrade to Autoconf 2.54 and Automake 1.7.

790 by Autoconf.
791 (AC_SUBST): Remove CFLAGS; now done by Autoconf.
793 * gzip.texi: Use the GNU FDL for distribution terms, following the
794 recipe in the Texinfo manual. Use Automake-generated variables
795 for date and version.
796 * fdl.texi, mdate-sh: New files.
797 * Makefile.am (AM_MAKEINFOFLAGS): Add --no-split.
798 (gzip_TEXINFOS): New macro.
800 * tailor.h (NO_DIR): Define to 1, not the empty string.
801 * gzip.c (NO_DIR): Define to 0 if not defined. All uses changed.
802 (usage): Don't put '#if' inside printf, as the C standard says
803 that it is not portable if printf is a macro.
805 Don't lose output when decompressing truncated input.
806 Bug reported by Nadav Har'El.
807 * inflate.c (GETBYTE): New macro.
808 (NEXTBYTE): Use it.
809 (inflate_dynamic, inflate_block): Add a local variable w, needed
810 by GETBYTE.
812 2002-03-08 Paul Eggert <eggert@twinsun.com>

815 configure.in (AM_INIT_AUTOMAKE): Revision 1.3.3, dated today.
817 * README-alpha: Now using latest stable GNU tools.
818 Using the latest tools allows gzip to build correctly on hosts
819 conforming to POSIX 1003.1-2001.
821 * configure.in (match): Use AC_LIBOBJ; Autoconf 2.53 requires it.
822 (LIBOBJS): No longer need to subst, since AC_LIBOBJ does it.
823 (AC_PREREQ): Bump to 2.53.
825 * Makefile.am (install-exec-hook, remove-installed-links):
826 Work even when configured with --program-transform-name.
828 * gzip.c (license_msg): Update copyright.
829 (z_len): Now of type size_t.
831 2001-11-03 Paul Eggert <eggert@twinsun.com>
833 * NEWS, README, revision.h, gzip.texi, configure.in (AM_INIT_AUTOMAKE):
834 Revision 1.3.2, dated today.

857 mkinstalldirs, texinfo.tex:
858 Sync with latest version in other packages.
860 * acinclude.m4, config.guess, config.sub: Remove.

877 * gzip.c (main):
878 Report error if -b operand is not a nonnegative integer.
879 (treat_file): Don't assume tab width is 8, or that characters are
880 one column wide.
881 (make_ofname): Use WARN to warn about unchanged files.
882 (get_method): "get newer version of gzip" -> "not supported"
883 (check_ofname): Use yesno instead of checking for 'y' ourselves.
884 (treat_file): Do not assume link count fits in int.
886 * gzip.h (yesno): New decl.
888 * util.c (display_ratio): Use floating point to compute ratio:
889 this avoids problems with integer overflow.
891 * zgrep.in: Add support for --, -H, -h, -L, -l, -C, -d, -m and
892 their long equivalents. Warn that -r and -d are not supported.
894 * zmore.in:
895 Check that file is readable before attempting to decompress it.
897 2000-10-09 Paul Eggert <eggert@twinsun.com>
899 * configure.in (AC_CHECK_FUNCS): Add lstat.
901 2000-07-20 Paul Eggert <eggert@twinsun.com>
903 Use a POSIX-compliant shell instead of /bin/sh.
904 Idea suggested by Albert Chin-A-Young <china@thewrittenword.com>.
906 * m4/shell.m4: New file.
907 * configure.in (AC_PROG_SHELL): Add it.
908 * Makefile.am (ACINCLUDE_INPUTS): Add $(M4DIR)/shell.m4.

927 * gzip.c (license_msg, usage, version, help, license):
928 Adjust to current GNU coding standards.
929 (total_in, total_out): Remove unnecessary initialization.
930 * zip.c (file_read): Report read errors.
931 * util.c (fill_inbuf): Likewise.
932 * gzip.c (main): Don't assume EOF == -1.
933 * unlzw.c (unlzw): Likewise.
