12007-02-05 Paul Eggert <eggert@cs.ucla.edu>
2
3 * NEWS: Version 1.3.11 released.
4 * configure.ac (AC_INIT): Likewise.
5
6 * doc/gzip.texi: Convert Texinfo format into a more modern style.
7 Put in current output samples.
8
9 * .cvsignore: Add *.gz, gunzip, zcat, zcmp, zegrep, zfgrep.
10 * lib/.cvsignore: Add sys_time_.h, unistd_.h.
11 * m4/.cvsignore: Add gnulib-common.m4, sys_time_h.m4.
12
13 * gunzip.in, zcat.in, zcmp.in, zegrep.in, zfgrep.in: New files.
14 * Makefile.am (EXTRA_DIST): Add them.
15 (bin_SCRIPTS, MOSTLYCLEANFILES): Add gunzip, zcat, zcmp, zdgrep, zfgrep.
16 (.in): Use GZIP_BINDIR as the location of gzip binaries, if it is set.
17 (check-local): Use GZIP_BINDIR.
18 (install-exec-hook, remove-installed-links): Make 'uncompress' an
19 alias for gunzip.
20 * gzexe.1: At least one arg is required. Don't give cat as an
21 example, since gzexe refuses to compress cat due to a bootstrapping
22 issue. List more utilities in this category.
23 * gzexe.in, zdiff.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
24 Report our name in usage.
25 * gzexe.in: Don't compress bash. Don't use rmdir, so it's
26 OK to compress rmdir.
27 * gzip.c: Now requires that you compile with -DGNU_STANDARD=0 to
28 get non GNU-standard behavior. We now build with GNU-standard
29 behavior by default, so that programs do not depend on the names
30 of their executables.
31 * zdiff.in: Don't depend on the name of the executable, as per
32 GNU standard. Instead, rely on an internal --__cmp option.
33 Support ' in options. Check for failures in subsidiary gzip
34 invocations.
35 * zgrep.1: Clarify compression issues.
36 * zgrep.in: Don't assume POSIX-style case syntax. Remove unused var
37 have_optarg.
38 * zless.1: zless sets LESSMETACHARS now.
39
402007-01-10 Paul Eggert <eggert@cs.ucla.edu>
41
42 * m4/shell.m4 (AC_PROG_SHELL): Test that $(...) works.
43 Problem reported for SGI IRIX 6 by Nelson H. F. Beebe in
44 <http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00007.html>.
45
462007-01-04 Paul Eggert <eggert@cs.ucla.edu>
47
48 * zdiff.in (cmp0): New var.
49 Rewrite test for /dev/fd/3 to detect bugs in Solaris 8
50 /bin/bash 2.03. Problem reported by Nelson H. F. Beebe in
51 <http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00001.html>.
52 Avoid "for file; do", which doesn't work with Solaris 8 /bin/sh.
53
542007-01-03 Paul Eggert <eggert@cs.ucla.edu>
55
56 * zdiff.in: Test /dev//fd/3, not /dev/fd/3, to work around a problem
57 with Tru64 4.0F ksh M-11/16/88f reported by Thomas Koutcher in
58 <http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00000.html>.
59
602006-12-30 Paul Eggert <eggert@cs.ucla.edu>
61
62 * NEWS: Version 1.3.10 released.
63 * configure.ac (AC_INIT): Likewise.
64
65 * Makefile.am (check-local): Don't assume $(srcdir) is '.'.
66 (MAINTAINERCLEANFILES): Move gzip.doc.gz from here ...
67 (MOSTLYCLEANFILES): ... to here.
68
692006-12-29 Paul Eggert <eggert@cs.ucla.edu>
70
71 * zless.in: Work around a bug in less 394 and earlier; it
72 mishandles $%=~ in file names. Problem reported by
73 Sami Liedes in <http://bugs.debian.org/383358>.
74
75 * doc/gzip.texi: Swap order of dircategory entries, to pacify
76 Debian install-info 1.10.28. This should fix
77 <http://bugs.debian.org/404048>.
78
79 * zgrep.in (version): Fix bug: $grep wasn't evaluated.
80
81 * zgrep.in: Rewrite to make the option processing more
82 compatible with GNU and POSIX grep. Assume POSIX shell
83 for more stuff, since we're already assuming that.
84 * Makefile.am (check-local): Check zgrep -iV.
85
862006-12-26 Paul Eggert <eggert@cs.ucla.edu>
87
88 Fix Debian bug 367673 <http://bugs.debian.org/367673> plus several
89 other bugs discovered in the neighborhood.
90 * NEWS: gzip -q now exits with status 2 (not 1) on SIGPIPE.
91 zgrep has many bugs fixed with argument handling, special characters,
92 and exit status.
93 * gzip.c (abort_gzip_signal): Implement gzip -q change.
94 * zgrep.in: Implement zgrep change.
95
962006-12-23 Paul Eggert <eggert@cs.ucla.edu>
97
98 * NEWS: Fix bug reported by Martin Mares in
99 <http://bugs.debian.org/177942>.
100 * gzip.c (treat_stdin): Remove NO_STDIN_FSTAT and NO_PIPE_TIMESTAMP
101 stuff. It didn't work (led to syntax errors) and was confusing.
102 Report an error if stdin cannot be statted even if !list && no_time.
103 Get stdin's size if it is regular.
104 (treat_file): Do not report an error with setuid, setgid,
105 sticky, or non-regular, non-directory files if to_stdout.
106 Allow 'force' to override the caution about sticky files.
107 Use the same form for time stamps that treat_stdin uses.
108
109 * zdiff.in: Fix typo that broke most usages. Problem reported by
110 Jari Aalto in <http://bugs.debian.org/404114>. While we're at it,
111 fix a bunch of other problems. Handle "-" better. Send
112 diagnostics to stderr, not stdout. Use expr rather than echo |
113 sed, to handle special characters better. Report a diagnostic in
114 the 1-arg case, if the argument doesn't end in .gz or the like,
115 rather than having incomprehensible behavior. Do not require that
116 the inputs be regular files. Avoid creating a temporary entirely,
117 if /dev/fd works. If not, then resist denial-of-service attacks
118 better, by using mktemp.
119 * NEWS: Document this.
120 * Makefile.am (gzip.doc.gz): New rule.
121 (check-local): Depend on it, and test zdiff for Debian bug 404114.
122
1232006-12-22 Paul Eggert <eggert@cs.ucla.edu>
124
125 * zdiff.1: Mention that these programs currently understand only
126 formats that gzip does. Problem reported by Jari Aalto in
127 <http://bugs.debian.org/404099>.
128
1292006-12-20 Paul Eggert <eggert@cs.ucla.edu>
130
131 * inflate.c (huft_build): Fix regression that caused gzip to
132 refuse to uncompress null input (all zero length codes). Problem
133 reported by Yiorgos Adamopoulos. This regression was caused by
134 the security patch installed 2006-11-20, which in turn came from
135 Debian, which in turn apparently came from Thomas Biege of SuSe.
136
1372006-12-15 Paul Eggert <eggert@cs.ucla.edu>
138
139 * NEWS, configure.ac (AC_INIT):
140 Version 1.3.9 released.
141
142 * Makefile.am (MOSTLYCLEANFILES): Add _match.i.
143 * configure.ac (for an assembler syntax supported by this package):
144 Remove _match.i.
145
146 * bootstrap (gnulib_tool_options_extras): New var.
147 (gnulib_tool_options): Use it.
148 * bootstrap.conf (gnulib_tool_options_extras): Avoid getline and
149 rpmatch. gzip doesn't need them, since it doesn't ENABLE_NLS.
150
1512006-12-13 Bruno Haible <bruno@clisp.org>
152
153 * configure.ac: Use $CPPFLAGS everywhere $CPP is used, and use
154 $CPPFLAGS $CFLAGS everywhere $CC is used.
155 * lib/Makefile.am (match.$(OBJEXT)): Likewise.
156 * configure.ac: Test the exit code of the $CPP and $ASCPPPOST commands
157 separately.
158
1592006-12-11 Paul Eggert <eggert@cs.ucla.edu>
160
161 * configure.ac (ASCPPPOST): Simplify to use just 'sed'.
162 * lib/Makefile.am (match.$(OBJEXT)): Check for CPP failure.
163
1642006-12-11 Bruno Haible <bruno@clisp.org>
165
166 Cross-compilation support.
167 * configure.ac (ASCPP): Remove substituted variable.
168 (ASCPPPOST, ASCPPFLAGS): New substituted variables.
169 * lib/Makefile.am (ASCPP, LN_S): Remove unnecessary macro definitions.
170 (match.$(OBJEXT)): Use CPP, ASCPPFLAGS, ASCPPPOST instead of ASCPP.
171 * configure.ac: Add test for chown function.
172 * gzip.c (treat_file) [!HAVE_CHOWN]: Don't call chown.
173 * gzip.c: Include "timespec.h". This doesn't fix any bugs, but
174 it is clearer.
175
1762006-12-11 Paul Eggert <eggert@cs.ucla.edu>
177
178 The SSIZE_MAX fix didn't work on NSK, so fix it in a more-reliable
179 (albeit more-complicated) way. Problem reported by Matthew Woehlke.
180 * gzip.h (read_buffer): New decl.
181 * unlzw.c (unlzw): Use read_buffer rather than read.
182 * zip.c (file_read): Likewise.
183 * util.c (copy, fill_inbuf): Likewise.
184 (read_buffer, write_buffer): New functions.
185 (write_buf): Use write_buffer rather than write.
186
187 Undo the previous SSIZE_MAX-related change; it didn't work.
188 * gzip.c: Include <limits.h>.
189 * util.c: Likewise.
190 * gzip.h: Don't include <limits.h>.
191 (INBUFSIZ): Don't worry about SSIZE_MAX here.
192
1932006-12-08 Paul Eggert <eggert@cs.ucla.edu>
194
195 * NEWS, configure.ac (AC_INIT):
196 Version 1.3.8 released.
197
198 * gzexe.in (mktemp_status): New var, used to see whether
199 mktemp is a known command. Use this instead of confounding
200 mktemp's existence with its success.
201
202 * zdiff.in: Remove first line containing ":". This follows
203 up on the SEDCMD fix of 2006-12-01.
204 * zforce.in: Likewise.
205 * zgrep.in: Likewise.
206 * zless.in: Likewise.
207 * zmore.in: Likewise.
208 * znew.in: Likewise.
209
210 Fix problems in porting to NSK reported by Matthew Woehlke in
211 <http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00025.html> and
212 <http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00027.html>.
213 * gzip.h: Include <limits.h>, for SSIZE_MAX.
214 (INBUFSIZE): Don't make it any larger than SSIZE_MAX.
215 Problem reported by Matthew Woehlke in
216 <http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
217 * gzip.c: Don't include <limits.h>, as gzip.h now does this.
218 * util.c: Likewise.
219 * gzip.c (main): Set exiting_signal before installing signal handlers.
220 (install_signal_handlers): Don't set exiting_signal here. This
221 fixes a C99ism.
222 * zip.c: Include timespec.h, for time_stamp type.
223
2242006-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
225
226 * gzexe.in: Work around FreeBSD shell trap bug.
227 * gzip.1: Fix typo.
228 * doc/gzip.texi: Likewise.
229
2302006-12-08 Paul Eggert <eggert@cs.ucla.edu>
231
232 * .cvsignore: Add .deps, gzexe, gzip, zdiff, zforce, zgrep,
233 zless, zmore, znew.
234 * doc/.cvsignore: Add Makefile.
235 * lib/.cvsignore: Add .deps, Makefile, alloca.h, config.h, fcntl.h,
236 stamp-h1, stdint.h, sys.
237
238 * configure.ac (for assembler): Set ASFLAGS_config to
239 -Wa,--noexecstack if this seems advisable on this platform.
240 Problem reported by Mike Frysinger in
241 <http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00018.html>.
242 * lib/Makefile.am (match.$(OBJEXT)): Use ASFLAGS_config.
243
2442006-12-07 Paul Eggert <eggert@cs.ucla.edu>
245
246 * Makefile.am (install-exec-hook): Fix bug when installing
247 symbolic links as aliases. Problem reported by Mike Frysinger.
248
249 * deflate.c (deflate_fast, deflate): Avoid core dump. Problem
250 originally reported by Jochen Friedrich and trivial patch supplied
251 by Anthony Towns; see <http://bugs.debian.org/184057>.
252
2532006-12-06 Paul Eggert <eggert@cs.ucla.edu>
254
255 * NEWS, configure.ac (AC_INIT):
256 Version 1.3.7 released.
257
2582006-12-06 Bruno Haible <bruno@clisp.org> (tiny change)
259 and Paul Eggert <eggert@cs.ucla.edu>
260
261 Fix build failure on case-insensitive file systems.
262 * configure.ac: Use match_.s instead of _match.s.
263 * Makefile.am (MOSTLYCLEANFILES): Likewise.
264 * lib/Makefile.am (match.$(OBJEXT)): Likewise.
265 (MOSTLYCLEANFILES): Likewise.
266
2672006-12-06 Paul Eggert <eggert@cs.ucla.edu>
268
269 * NEWS: Document the fixes below.
270 * configure.ac (AC_CHECK_FUNCS_ONCE): Add siginterrupt.
271 * gzip.c (lstat) [!defined(HAVE_LSTAT) && !defined(lstat)]: Remove.
272 (SA_NOCLDSTOP, sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
273 New macros.
274 (siginterrupt) [!defined SA_NOCLDSTOP && ! HAVE_SIGINTERRUPT]:
275 New macro.
276 (HAVE_WORKING_O_NOFOLLOW): Define to 0 if not defined.
277 (caught_signals, exiting_signal, remove_ofname_fd): New vars.
278 (remove_ofname): Remove; all uses changed to remove_ofname_fd.
279 (same_file, name_too_long): Remove.
280 (install_signal_handlers): New function. It prefers sigaction,
281 which is more reliable in the presence of race conditions.
282 Catch SIGXCPU and SIGXFSZ, too.
283 (main): Use it instead of installing them by hand.
284 (treat_file): Check for read error when closing ifd.
285 (treat_file, create_outfile, remove_output_file):
286 Avoid race conditions with signals.
287 (create_outfile, check_ofname): Remove most of the gorp about
288 working around ENAMETOOLONG deficiencies. It's obsolete now, and
289 anyway it had race conditions. Just rely on O_EXCL and
290 ENAMETOOLONG. The worst that can happen is that a file name will
291 be silently truncated on an obsolete machine, but no data will be lost.
292 (open_and_stat): Use HAVE_WORKING_O_NOFOLLOW rather than O_NOFOLLOW
293 to work around some O_NOFOLLOW bugs. Otherwise, fall back on
294 lstat only if lstat is available, as symlinks don't exist otherwise.
295 (open_input_file): Use O_NONBLOCK and O_NOCTTY too, to avoid
296 hanging gzip on special files.
297 (abort_gzip_signal): If sigaction is not available, ignore
298 signals. If we get the exiting signal, exit with ERROR status
299 rather than raising a signal.
300 * tailor.h (NO_ST_INO): Remove; no longer used now that same_file
301 is gone.
302
3032006-12-05 Paul Eggert <eggert@cs.ucla.edu>
304
305 Port to Tandem NSK/OSS, which lacks fchdir. Problem reported by
306 Matthew Woehlke in
307 <http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
308 * bootstrap.conf (gnulib_modules): Remove openat, as it pulls in
309 fchdir.
310 * configure.ac: Check for fdopendir.
311 * gzip.c: Don't include openat.h; no longer needed.
312 (treat_dir) [!HAVE_FDOPENDIR]: Fall back on the old opendir method
313 since fdopendir is not available.
314
3152006-12-04 Paul Eggert <eggert@cs.ucla.edu>
316
317 * NEWS: Describe the following change briefly.
318 * bootstrap.conf (gnulib_modules): Remove stat-macros; no longer
319 needed.
320 * gzip.c: Don't include stat-macros.h; no longer needed.
321 (treat_file): Refuse to compress files that are setuid, or setgid,
322 as this can in theory lead to security holes. Also, refuse to
323 compress files with the sticky bit set, on general principle.
324 (copy_stat): Don't copy the setuid, setgid, or sticky bits,
325 as (given the above change) they'll always be zero here.
326 Invoke chmod before chown, to close a race condition.
327
328 * .cvsignore: Add *.doc, build-aux.
329 * doc/.cvignore: New file.
330 * lib/.cvsignore: New file.
331 * m4/.cvsignore: New file.
332
3332006-12-01 Paul Eggert <eggert@cs.ucla.edu>
334
335 * doc/gzip.texi (Overview): Mention limits of gzip format's
336 time stamps. Also, gzip doesn't always preserve time stamps.
337
338 * gzip.c (abort_gzip_signal): Don't call abort () as a "safeguard",
339 since it actually causes a core dump. Problem reported by
340 Jakub Bogusz.
341
342 * NEWS: Describe gzexe changes noted below.
343 * Makefile.am (.in): Don't bother with SEDCMD. This stuff isn't needed
344 any more (the hosts it caters to are long extinct), and was
345 questionable anyway since the code assumes the skip= line was line 2.
346 * configure.ac (AC_SYS_INTERPRETER, SEDCMD): Remove; no longer needed.
347
348 * gzexe.in: Sweep the code and fix some bugs.
349 My, what sharp teeth you have, gzexe!
350 The straw that broke this camel's back was Matthew Burgess's bug report
351 <http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00012.html>.
352
353 (IFS): Set it to the standard value, both here and in the
354 script gzexe generates.
355 Check for missing operand after parsing options, not before.
356 This fixes the case for "cpexe --".
357 Check for tail -n problem separately in gzexe and in the executable
358 it generates, in case it's a different 'tail'.
359 (trap): Remove $tmp only if $tmp is not the empty string.
360 Preserve exit status.
361 Don't use the nonstandard (and rarely available) "cpmod" utility.
362 Don't use "set -C"; it's no longer useful and it breaks things
363 in some cases.
364 (main loop): Handle file names beginning with "-".
365 Exit with status of failing program, not with 1.
366 Fix some bugs in printing diagnostics, and in quoting.
367 Require the skip= line to have at least one digit.
368 Use test -u and test -g rather than using the (less-reliable) ls.
369 Refuse to compress more programs, e.g., sh.
370 Use mktemp rather than tempfile. Build a copy of
371 the compressed or uncompressed executable in the same
372 directory as the executable, as that's less likely to go wrong
373 if disk space is low. Have the executable exit with status 127,
374 not 1, if the decompression process fails; this is more compatible
375 with meta-programs like nohup. Have the executable
376 uncompress to a temp file with the same basename as the executable;
377 this is more likely to go right. Fix a race condition where the
378 executable temporarily did not exist (in either old or new forms).
379 Check for race conditions better when mv fails. Do not attempt
380 to use cp to do the real work, only to copy permissions to a temp
381 file, since we don't want to trash running executables.
382
3832006-11-26 Paul Eggert <eggert@cs.ucla.edu>
384
385 * inflate.c (inflate_dynamic, inflate): Don't send output to
386 stderr unless DEBUG is defined and 'verbose'. Problem reported by
387 Santiago Vila.
388
389 * zgrep.in: If the file name contains newline, &, \, or |, escape
390 the character so that 'sed' doesn't mishandle it as a replacement.
391 Problem reported by Bdale Garbee.
392
3932006-11-25 Paul Eggert <eggert@cs.ucla.edu>
394
395 * gzip.1 (OPTIONS): ouput -> output. Problem reported by Matt
396 Taggart.
397 * vms/gzip.hlp: Likewise.
398
399 * Makefile.am (FILES_TO_CHECK): New macro.
400 (check-local): Check only the files in FILES_TO_CHECK, since some
401 files under the working directory might be mutating as the test is
402 run, e.g., with "make check >log". Problem reported by Jim
403 Meyering.
404
4052006-11-20 Paul Eggert <eggert@cs.ucla.edu>
406

428 (gl_EARLY, gl_INIT): New.
429 match.c was moved to lib/match.c.
430 (AC_CHECK_HEADERS_ONCE): Replace AC_CHECK_HEADERS. Don't check
431 for sys/utime.h or utime.h.
432 (AC_CHECK_FUNCS_ONCE): Replace AC_CHECK_FUNCS. Check for fchmod
433 and fchown, not utime.
434 (AC_REPLACE_FUNCS): Remove; rpmatch is now done by gnulib.
435 (AC_CONFIG_FILES): Add doc/Makefile, lib/Makefile.
436
437 * bits.c: Use the more-usual form for copyright notices in source code.
438 * deflate.c: Likewise.
439 * gzip.c: Likewise.
440 * gzip.h: Likewise.
441 * inflate.c: Likewise.
442 * lzw.h: Likewise.
443 * revision.h: Likewise.
444 * tailor.h: Likewise.
445 * trees.c: Likewise.
446 * unpack.c: Likewise.
447 * unzip.c: Likewise.
448 * util.c: Likewise.
449 * crypt.c (dummy): Add decl so that pedantic compilers won't
450 complain about an empty file.
451 * gzip.c (license_msg): Use more-modern wording.
452 Include fcntl-safer.h, openat.h, stat-macros.h, stat-time.h.
453 Simply include <dirent.h> if !NO_DIR, removing a rats-nest of
454 #ifdefs.
455 Simply include <utimens.h> if !defined NO_UTIME, removing a
456 another rats-nest of #ifdefs.
457 (DIR_OPT, TIME_OPT): Remove.
458 (_D_EXACT_NAMLEN): Renamed from NAMLEN. All uses changed.
459 (S_ISDIR, S_ISREG, O_BINARY, O_CREAT, O_EXCL, S_IRUSR, S_IWUSR):
460 Remove; gnulib now does this.
461 (RETSIGTYPE): Remove; Autoconf does this.
462 (program_name): Renamed from progname, for compatibility with gnulib.
463 All uses changed.
464 (time_stamp): Now struct timespec, not time_t. All uses changd.
465 (remove_oftime): Now volatile.
466 (reset_times): Remove; now done by futimens.
467 (usage): Remove.
468 (try_help): New function.
469 (help, license): Don't output date as part of version.
470 A version number suffices.
471 (help): Redo help message to match style of coreutils etc.
472 (version): Don't bother printing compile-time configuration info
473 like STDC_HEADERS.
474 (main): Don't assume strlen (argv[0]) < INT_MAX (!).
475 On usage errors, suggest --help without outputting all the help.
476 (main, do_list): Remove unnecessary casts.
477 (treat_stdin, treat_file, get_method, copy_stat):
478 Support sub-second time stamp resolution.
479 (treat_file, copy_istat): Close some race conditions if files are
480 renamed as we read or write them.
481 (treat_file): Do not attempt to reset the access times of
482 directories that we read.
483 (open_and_stat, open_input_file): New functions.
484 (do_stat, get_istat): Remove; most of the contents went to these new
485 functions.
486 (make_ofname): Don't use WARN, as it affects exit status.
487 (get_method): When the original file name was truncated,
488 restore from its base name, not from its full name.
489 (do_list): Avoid undefined behavior with out-of-range time stamps.
490 ctime, for example, cannot be invoked on arbitrary time stamps safely,
491 since it might overrun an internal buffer. Do not assume that
492 localtime succeeds.
493 (copy_stat): Do not remove input file; that's now the caller's
494 responsibility. This avoids a problem if there is a write error
495 when the caller closes the output file.
496 (treat_dir): New arg FD, to avoid a race condition. All uses changed.
497 (remove_output_file): New function.
498 (abort_gzip): Use it.
499 (abort_gzip_signal): New function, which is async-signal-safe.
500 Exit with the signal that we got.

502 match gzip.c changes.
503 * inflate.c (huft_build): Return 2 if null input.
504 * tailor.h (HAVE_UTIME): Do not define; gnulib does this now.
505 (OPEN): Use open_safer, not plain open.
506 * unlzh.c (NPT): Set to 1<<TBIT, not to the maximum of NT and NP.
507 (make_table): Report an error if 1<<tablebits < nextcode.
508 (read_pt_len): Report an error if 16 < c.
509 * unpack.c (read_tree): Report an error if the tree has too many
510 leaves while reading it. Fix off-by-one error in final check.
511 * util.c: Include <xalloc.h>, for xalloc_die decl.
512 (gzip_base_name): Renamed from base_name, so we don't collide
513 with gnulib. All uses changed.
514 (add_envopt): Use xstrdup instead of xmalloc+strcpy.
515 Use xcalloc rather than calloc + check.
516 (gzip_error): Renamed from error, so we don't collide with gnulib.
517 All uses changed.
518 (xalloc_die): New function.
519 (xmalloc): Remove; no longer needed.
520 * zip.c (zip): Watch for time stamp overflow; the old code
521 mishandled negative time stamps.
522
523 * gzexe.in: Add support for --help, --version, --.
524 Don't call basename or sed if we can avoid it.
525 * zdiff.in: Likewise.

531 * zdiff.in: Protect against file names beginning with "-".
532 * zmore.in: Likewise.
533 * zgrep.in: Use printf rather than echo, to avoid problems with
534 leading "-" and backslash. Return status of subsidiary grep.
535 * zless.in: Add copyright notice.
536
537 * zless.1: We now pass "--" to LESSOPEN.
538 (BUGS): Mention that input file arguments are required.
539 Add copyright notice.
540
541 * COPYING: Update to current version.
542
543 * Makefile.am (SUBDIRS): New macro.
544 (AUTOMAKE_OPTIONS): Remove; now done in configure.ac.
545 (M4DIR, ACINCLUDE_INPUTS): Remove.
546 (EXTRA_DIST): Remove getopt.h.
547 (gzip_SOURCES): Remove getopt.c, getopt1.c, yesno.c.
548 (gzip_LDADD): Change from @LIBOBJS@ to lib/libgzip.a.

550 (match.$(OBJEXT)): Move to subdirectory makefiles.
551 (.in): Substitute @VERSION@, too.
552 (check-local): New rule.
553 (MOSTLYCLEANFILES): Add _match.S.
554
555 * doc/gzip.texi: Renamed from gzip.texi. Change to GNU FDL
556 without invariant sections or cover texts. Don't put
557 version number or date into sample gzip -h output.

559 written by Sverre Jarp (HP Labs).
560

585
586 * NEWS, README, revision.h, configure.in (AM_INIT_AUTOMAKE):
587 Revision 1.3.5, dated today.
588
589 * util.c (fprint_off): Fix bug in printing values greater than
590 10 * 2**32 bytes. Bug reported by Bryan Andersen.
591
592 * Makefile.am (match.$(OBJEXT)): Use .S as extension for $(ASCPP),
593 to keep gcc happy.
594 * configure.in: Likewise.
595 Upgrade assembly-language checking for Autoconf 2.54, using cache vars.
596 (AC_PROG_CPP, AC_OBJEXT): Add.
597
598 * match.c: Accept __i386 and __i386__ as synonyms for i386.

600
6012002-09-29 Paul Eggert <eggert@twinsun.com>
602
603 * gzip.texi (Overview): Suggest how to use gunzip on zip files.
604
605 * zless.1, zless.in: Use LESSOPEN, not PAGER.
606 Suggested by <antos@MAST.queensu.ca>.
607
6082002-09-28 Paul Eggert <eggert@twinsun.com>
609
610 * zforce.in: Use shell pattern matching instead of 'expr', which
611 mishandles names like "+". Remove old check for 14-byte file
612 names on hosts with broken "mv" implementations, as such systems
613 aren't in use any more and it's better nowadays to support file
614 names longer than 14 bytes. Rely on "mv"'s error-reporting.
615 This fixes a portability bug reported by Ralf Neubauer, along
616 with some other bugs.
617
618 Remove dangling output symlinks properly.
619 Bug reported by Kalle Olavi Niemitalo.

625
626 * zforce.in: Use "gzip -lv", not "gzip -v". Patch by Ralf
627 Neubauer.
628
629 * configure.in (ASCPP): Don't use test -a, as POSIX says it's
630 not portable.
631 * znew.in: Likewise.
632 * zmore.in: Likewise. Similarly, don't use test -o, or test -t
633 with no operand.
634
635 * gzexe.in (PATH): Set to same as other programs.
636 Don't assume "tail +22" works; POSIX removed this.
637 Check against compressing "tail".
638 Check against "skip=" line with no integer.
639 * zgrep.in: Exit with status 2 if trouble, for consistency with grep.
640
641 * gzip.c (main): Avoid core dump in diagnostic message if
642 incorrect suffix is given.
643
6442002-09-26 Paul Eggert <eggert@twinsun.com>
645
646 * zdiff.in: Use "trap -" instead of "trap". Patch by Nicolas Boullis.

658 (AC_HEADER_STDC): Renamed from AC_STDC_HEADERS.
659 (AC_CHECK_HEADERS): Remove stdlib.h, string.h, unistd.h; now done
660 by Autoconf.
661 (AC_SUBST): Remove CFLAGS; now done by Autoconf.
662
663 * gzip.texi: Use the GNU FDL for distribution terms, following the
664 recipe in the Texinfo manual. Use Automake-generated variables
665 for date and version.
666 * fdl.texi, mdate-sh: New files.
667 * Makefile.am (AM_MAKEINFOFLAGS): Add --no-split.
668 (gzip_TEXINFOS): New macro.
669
670 * tailor.h (NO_DIR): Define to 1, not the empty string.
671 * gzip.c (NO_DIR): Define to 0 if not defined. All uses changed.
672 (usage): Don't put '#if' inside printf, as the C standard says
673 that it is not portable if printf is a macro.
674
675 Don't lose output when decompressing truncated input.
676 Bug reported by Nadav Har'El.
677 * inflate.c (GETBYTE): New macro.
678 (NEXTBYTE): Use it.

688 Using the latest tools allows gzip to build correctly on hosts
689 conforming to POSIX 1003.1-2001.
690
691 * configure.in (match): Use AC_LIBOBJ; Autoconf 2.53 requires it.
692 (LIBOBJS): No longer need to subst, since AC_LIBOBJ does it.
693 (AC_PREREQ): Bump to 2.53.
694
695 * Makefile.am (install-exec-hook, remove-installed-links):
696 Work even when configured with --program-transform-name.
697

720
7212001-09-30 Paul Eggert <eggert@twinsun.com>
722
723 * NEWS, README, revision.h, gzip.texi, configure.in (AM_INIT_AUTOMAKE):
724 Revision 1.3.1, dated today.
725

744 (AC_AIX, AC_MINIX): Move earlier.
745 (AC_REPLACE_FUNCS): Add rpmatch.
746
747 * gzip.c (main):
748 Report error if -b operand is not a nonnegative integer.
749 (treat_file): Don't assume tab width is 8, or that characters are
750 one column wide.
751 (make_ofname): Use WARN to warn about unchanged files.
752 (get_method): "get newer version of gzip" -> "not supported"
753 (check_ofname): Use yesno instead of checking for 'y' ourselves.
754 (treat_file): Do not assume link count fits in int.
755
756 * gzip.h (yesno): New decl.
757

774 Idea suggested by Albert Chin-A-Young <china@thewrittenword.com>.
775
776 * m4/shell.m4: New file.
777 * configure.in (AC_PROG_SHELL): Add it.
778 * Makefile.am (ACINCLUDE_INPUTS): Add $(M4DIR)/shell.m4.

7812000-04-17 Bruno Haible <haible@clisp.cons.org>
782
783 * Makefile.am (install-exec-hook): If hard links fail, try symlinks.

807
808 * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS):
809 Work around a bug in the QNX shell, which doesn't
810 propagate exit status of failed commands inside shell assignments.
811
8121999-10-07 Paul Eggert <eggert@twinsun.com>
813
814 * NEWS, README, revision.h, gzip.texi:

843 unlzw.c, unpack.c, unzip.c, util.c, zip.c: Include <config.h>
844 first; this is needed for proper large-file support, given the new
845 way of configuring large files.

8521999-06-25 Paul Eggert <eggert@twinsun.com>
853
854 * inflate.c (huft_build):

857
8581999-06-24 Paul Eggert <eggert@twinsun.com>
859
860 * Makefile.in (check): Update texinfo.tex size.
861
862 * configure.in (ASMV):
863 Define with AC_DEFINE; do not manipulate DEFS directly,
864 as this doesn't work with recent autoconf versions.
865
8661999-02-06 Paul Eggert <eggert@twinsun.com>
867
868 * NEWS, README, revision.h, gzip.texi: Revision 1.2.4.4294967305,

1326
1327 * version 1.0.5
1328 For VMS, restore the file type for variable record format, otherwise
