* Merge with Debian testing. Remaining Ubuntu changes:
- debian/{control,rules}: Remove the Win32 build and mingw64
build-dependency, since mingw is in universe, and will remain so for
the forseeable future.

62
<http://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00006.html>.

65
66

Also, check for buggy shells that require ";;" before "esac".
70

72
73
* NEWS: Version 1.3.12 released.

75
76
* README: Update year in copyright notice.
77
* m4/shell.m4: Add copyright notice.
78
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,

94
95
2007-03-29 Paul Eggert <eggert@cs.ucla.edu> (tiny change)
96
97
* znew.in (tmp): Use $TMPDIR as temp directory, if given.

Suggested by Juan Manuel Guerrero.
99
100
2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
101
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>.
111
112
2007-03-14 Paul Eggert <eggert@cs.ucla.edu>
113
114
* README (WARNING): Reword to avoid mention of no-longer-existing
115
section in INSTALL file. Problem reported by Paul Townsend in
116
<http://lists.gnu.org/archive/html/bug-gzip/2007-03/msg00000.html>.
117
118
2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
119
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.
123
124
2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
125
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
<http://lists.gnu.org/archive/html/bug-gzip/2007-02/msg00005.html>.
130
131
2007-02-05 Paul Eggert <eggert@cs.ucla.edu>
132
133
* NEWS: Version 1.3.11 released.
134
* configure.ac (AC_INIT): Likewise.
135
136
* doc/gzip.texi: Convert Texinfo format into a more modern style.
137
Put in current output samples.
138
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.
142
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.
169
170
2007-01-10 Paul Eggert <eggert@cs.ucla.edu>
171
172
* m4/shell.m4 (AC_PROG_SHELL): Test that $(...) works.
173
Problem reported for SGI IRIX 6 by Nelson H. F. Beebe in
174
<http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00007.html>.
175
176
2007-01-04 Paul Eggert <eggert@cs.ucla.edu>
177
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
<http://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.
183
184
2007-01-03 Paul Eggert <eggert@cs.ucla.edu>
185
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
<http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00000.html>.
189
190
2006-12-30 Paul Eggert <eggert@cs.ucla.edu>
191
192
* NEWS: Version 1.3.10 released.
193
* configure.ac (AC_INIT): Likewise.
194
195
* Makefile.am (check-local): Don't assume $(srcdir) is '.'.
196
(MAINTAINERCLEANFILES): Move gzip.doc.gz from here ...
197
(MOSTLYCLEANFILES): ... to here.
198
199
2006-12-29 Paul Eggert <eggert@cs.ucla.edu>
200
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 <http://bugs.debian.org/383358>.
204
205
* doc/gzip.texi: Swap order of dircategory entries, to pacify
206
Debian install-info 1.10.28. This should fix
207
<http://bugs.debian.org/404048>.
208
209
* zgrep.in (version): Fix bug: $grep wasn't evaluated.
210
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.
215
216
2006-12-26 Paul Eggert <eggert@cs.ucla.edu>
217
218
Fix Debian bug 367673 <http://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.
225
226
2006-12-23 Paul Eggert <eggert@cs.ucla.edu>
227
228
* NEWS: Fix bug reported by Martin Mares in
229
<http://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 time stamps that treat_stdin uses.
238
239
* zdiff.in: Fix typo that broke most usages. Problem reported by
240
Jari Aalto in <http://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.
252
253
2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
254
255
* zdiff.1: Mention that these programs currently understand only
256
formats that gzip does. Problem reported by Jari Aalto in
257
<http://bugs.debian.org/404099>.
258
259
2006-12-20 Paul Eggert <eggert@cs.ucla.edu>
260
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.
266
267
2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
268
269
* NEWS, configure.ac (AC_INIT):
270
Version 1.3.9 released.
271
272
* Makefile.am (MOSTLYCLEANFILES): Add _match.i.
273
* configure.ac (for an assembler syntax supported by this package):
274
Remove _match.i.
275
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.
280
281
2006-12-13 Bruno Haible <bruno@clisp.org>
282
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 $ASCPPPOST commands
287
separately.
288
289
2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
290
291
* configure.ac (ASCPPPOST): Simplify to use just 'sed'.
292
* lib/Makefile.am (match.$(OBJEXT)): Check for CPP failure.
293
294
2006-12-11 Bruno Haible <bruno@clisp.org>
295
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.
305
306
2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
307
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.
316
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.
322
323
2006-12-08 Paul Eggert <eggert@cs.ucla.edu>
324
325
* NEWS, configure.ac (AC_INIT):
326
Version 1.3.8 released.
327
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.
331
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.
339
340
Fix problems in porting to NSK reported by Matthew Woehlke in
341
<http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00025.html> and
342
<http://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
<http://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.
353
354
2006-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
355
356
* gzexe.in: Work around FreeBSD shell trap bug.
357
* gzip.1: Fix typo.
358
* doc/gzip.texi: Likewise.
359
360
2006-12-08 Paul Eggert <eggert@cs.ucla.edu>
361
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.
367
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
<http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00018.html>.
372
* lib/Makefile.am (match.$(OBJEXT)): Use ASFLAGS_config.
373
374
2006-12-07 Paul Eggert <eggert@cs.ucla.edu>
375
376
* Makefile.am (install-exec-hook): Fix bug when installing
377
symbolic links as aliases. Problem reported by Mike Frysinger.

385
* NEWS, configure.ac (AC_INIT):
386
Version 1.3.7 released.
387
388
2006-12-06 Bruno Haible <bruno@clisp.org> (tiny change)
389
and Paul Eggert <eggert@cs.ucla.edu>
390
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

398
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.
432
433
2006-12-05 Paul Eggert <eggert@cs.ucla.edu>
434
435
Port to Tandem NSK/OSS, which lacks fchdir. Problem reported by
436
Matthew Woehlke in
437
<http://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.
444
445
2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
446
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.
457
458
* .cvsignore: Add *.doc, build-aux.
459
* doc/.cvignore: New file.
460
* lib/.cvsignore: New file.
461
* m4/.cvsignore: New file.
462
463
2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
464
465
* doc/gzip.texi (Overview): Mention limits of gzip format's
466
time stamps. Also, gzip doesn't always preserve time stamps.
467
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.
471
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.
477
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
<http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00012.html>.
482
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.
512
513
2006-11-26 Paul Eggert <eggert@cs.ucla.edu>
514
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.
518
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.
522
523
2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
524
525
* gzip.1 (OPTIONS): ouput -> output. Problem reported by Matt
526
Taggart.
527
* vms/gzip.hlp: Likewise.
528
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.
534
535
2006-11-20 Paul Eggert <eggert@cs.ucla.edu>
536

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.
553
Input is now lib/config.hin.
554
(AM_INIT_AUTOMAKE): Add gnits, dist-shar.
555
(AC_PROG_CC_STDC): New, replacing AC_PROG_CC.
556
(AM_PROG_CC_C_O, AC_PROG_RANLIB): New.
557

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.
566
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 time stamp 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 time stamps.
620
ctime, for example, cannot be invoked on arbitrary time stamps 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 time stamp overflow; the old code
651
mishandled negative time stamps.
652
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.

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.
666
667
* zless.1: We now pass "--" to LESSOPEN.
668
(BUGS): Mention that input file arguments are required.
669
Add copyright notice.
670
671
* COPYING: Update to current version.
672
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.
679
(AM_MAKEINFOFLAGS, info_TEXINFOS, gzip_TEXINFOS, ASCPP, LN_S):
680
(match.$(OBJEXT)): Move to subdirectory makefiles.
681
(.in): Substitute @VERSION@, too.
682
(check-local): New rule.
683
(MOSTLYCLEANFILES): Add _match.S.
684
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).
690
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.

715
716
* NEWS, README, revision.h, configure.in (AM_INIT_AUTOMAKE):
717
Revision 1.3.5, dated today.
718
719
* util.c (fprint_off): Fix bug in printing values greater than
720
10 * 2**32 bytes. Bug reported by Bryan Andersen.
721
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.
727
728
* match.c: Accept __i386 and __i386__ as synonyms for i386.
729
Bug reported by "fork __" <bouloumag@hotmail.com>.
730
731
2002-09-29 Paul Eggert <eggert@twinsun.com>
732
733
* gzip.texi (Overview): Suggest how to use gunzip on zip files.
734
735
* zless.1, zless.in: Use LESSOPEN, not PAGER.
736
Suggested by <antos@MAST.queensu.ca>.
737
738
2002-09-28 Paul Eggert <eggert@twinsun.com>
739
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.
747
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.
753
754
2002-09-27 Paul Eggert <eggert@twinsun.com>
755
756
* zforce.in: Use "gzip -lv", not "gzip -v". Patch by Ralf
757
Neubauer.
758
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.
764
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.
770
771
* gzip.c (main): Avoid core dump in diagnostic message if
772
incorrect suffix is given.
773
774
2002-09-26 Paul Eggert <eggert@twinsun.com>
775
776
* zdiff.in: Use "trap -" instead of "trap". Patch by Nicolas Boullis.
777
Use names, not numbers, for signals. Patch by Andrew Stribblehill.
778
779
* NEWS, README, revision.h, configure.in (AM_INIT_AUTOMAKE):
780
Revision 1.3.4, dated today.
781
782
* README-alpha: Upgrade to Autoconf 2.54 and Automake 1.7.
783
* configure.in (AC_PREREQ): Move to start, and increase to 2.54.
784
(AC_INIT, AM_INIT_AUTOMAKE, AC_CONFIG_SRCDIR, AC_CONFIG_FILES,
785
AC_OUTPUT): Use modern style.
786
(AC_OBJEXT, AC_EXEEXT): Remove; obsolete.
787
(AC_GNU_SOURCE): Add.
788
(AC_HEADER_STDC): Renamed from AC_STDC_HEADERS.
789
(AC_CHECK_HEADERS): Remove stdlib.h, string.h, unistd.h; now done
790
by Autoconf.
791
(AC_SUBST): Remove CFLAGS; now done by Autoconf.
792
793
* gzip.texi: Use the GNU FDL for distribution terms, following the
794
recipe in the Texinfo manual. Use Automake-generated variables
