8 gzexe: port to macOS mktemp
9 Problem reported by Jeffrey Walton (Bug#30000).
10 * gzexe.in, zdiff.in, zgrep.in:
11 Don’t assume that mktemp works when given no arguments,
12 as this is not true for macOS. Instead, use a syntax
13 that should work with coreutils, NetBSD, and macOS.
14 While we’re in the neighborhood, be more consistent about how program
15 names are used in temporary file names. Also, watch out for TMPDIR
16 values that are not absolute file names, since they can cause problems

21 maint: update gnulib and copyright dates for 2018
22 * gnulib: Update to latest.
23 * bootstrap: Update from gnulib.
24 * all files: Run "make update-copyright".
26 2017-12-16 Jim Meyering <meyering@fb.com>
28 build: update gnulib to latest
30 2017-11-24 Paul Eggert <eggert@cs.ucla.edu>
32 maint: zforce and zmore exit status cleanup
33 Problem reported by Nelson H. F. Beebe.
34 * zforce.in, zmore.in: On failure, exit with status 1 instead of
35 with whatever failing status that printf or mv exited with.
37 2017-11-23 Paul Eggert <eggert@cs.ucla.edu>
39 gzexe: ensure file always exists
40 * gzexe.in: When in a filesystem that does not support symlinks,
41 use rm+cp rather than mv to make backups, so that the argument

46 build: update gnulib to latest
48 2017-11-16 Jim Meyering <meyering@fb.com>
50 gzexe: work even without the ability to make a hard link
51 * gzexe.in: When ln -f fails to create a "~"-style backup,
52 fall back to using mv -f.
53 Reported by Bruno Haible in http://debbugs.gnu.org/29266
55 2017-11-15 Jim Meyering <meyering@fb.com>
57 build: make each generated script unwritable
58 * Makefile.am (.in): Ensure that each generated script is unwritable.
59 This makes it less likely that someone (even me) will mistakenly
60 modify one of those generated files.
62 2017-11-13 Jim Meyering <meyering@fb.com>
64 zless, znew: exit 1 upon --help or --version write failure
65 * zless.in: Exit 1 upon --help or --version write error.
68 2017-11-12 Paul Eggert <eggert@cs.ucla.edu>
70 maint: script diagnostics status cleanup
71 Problem reported by Bruno Haible (Bug#29266#20).
73 * gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zforce.in:
74 * zgrep.in, zless.in, zmore.in, znew.in:
75 Use printf instead of echo if the argument might contain ‘\’, at
76 least in theory. Don’t assume printf exits with status 1 on
77 failure; it might be some other positive status.
78 * gzexe.in: Use printf consistently instead of echo, and
79 proscribe it instead of echo.
81 tests: don’t be so strict about timestamps
82 * tests/timestamp: We’ve had many false alarms about timestamps
83 that are not gzip problems, but instead are problems with ‘touch’.
84 Attempt to work around them by not trusting ‘touch’ so much.
85 Problems and parts of solutions proposed by Bruno Haible.
87 2017-11-10 Paul Eggert <eggert@cs.ucla.edu>
89 build: update gnulib submodule to latest
91 2017-11-09 Jim Meyering <meyering@fb.com>
93 gnulib: update to latest
95 maint: use noreturn, not ATTRIBUTE_NORETURN
96 Use gnulib's stdnoreturn module so we can include
97 <stdnoreturn.h> and the "noreturn" helper macro, thus
98 replacing the definition and uses of ATTRIBUTE_NORETURN.
99 * bootstrap.conf (gnulib_modules): Add stdnoreturn.
100 * gzip.h (ATTRIBUTE_NORETURN): Remove definition.
101 Include stdnoreturn.h and use "noreturn" for each
102 ATTRIBUTE_NORETURN-adorned function declaration.
103 * gzip.c (do_exit, try_help): Use "noreturn".
105 tests: unpack-invalid: correct and clean up a test
106 * tests/unpack-invalid: There was a logic error that would have
107 caused this test to ignore a failure if first iteration of the
108 loop set fail=1 and the second one reset it to 0. Also, use
109 "returns_ 1 ...", to require an exit status of 1.
111 2017-11-07 Paul Eggert <eggert@cs.ucla.edu>
113 gzip: diagnose out-of-range MTIME
114 This seems to be the problem reported by Bruno Haible for GNU/Hurd
115 i386 with touch 8.26 and glibc 2.24 (Bug#29033#20).
116 * NEWS: Document this.
117 * gzip.c (get_method): If MTIME is out of range for
118 this platform, warn and substitute the nearest in-range
119 value, instead of silently ignoring it.
120 (do_list): Remove no-longer-needed test for unknown time stamp.
122 2017-11-06 Paul Eggert <eggert@cs.ucla.edu>
124 misc: diagnose year-2038 configuration problems
125 * bootstrap.conf (gnulib_modules): Add year2038.
126 * m4/.gitignore: Add year2038.m4[
128 maint: remove IMPORT_FROM_GETTEXT
129 * bootstrap.conf (IMPORT_FROM_GETTEXT): Remove.
130 This is a relic from older Gnulib, and has no effect now.
132 2017-10-29 Jim Meyering <meyering@fb.com>
134 tests/unpack-valid: port to printf that do not grok hex
135 Many versions of printf do not handle hexadecimal in a format string,
136 so this test would fail.
137 * tests/init.cfg (hex_printf_): Copied from grep's tests/init.cfg.
138 * tests/unpack-valid: Use hex_printf_.
139 Reported by Bruno Haible in https://bugs.gnu.org/29033#26
141 gnulib: update to latest; also update tests/init.sh from gnulib
143 gzip: fix bug with any upper case custom ('-S'-specified) suffix
144 Any user-specified suffix with an upper case
145 letter would fail to match desired file.
146 * gzip.c (get_suffix): First, arrange to have only one return
147 point rather than two. Put a lower-cased (just-malloc'd) copy
148 of z_suffix in the suffix vector, and free it before returning.
149 * tests/upper-suffix: New file.
150 * tests/Makefile.am (TESTS): Add it.
152 Reported by meo@xenialab.it in https://bugs.gnu.org/29006
154 2017-10-16 Paul Eggert <eggert@cs.ucla.edu>
156 gzip: fix bug in unpack EOB check
157 Problem reported by Vidar Holen (Bug#28861).
159 * tests/unpack-valid: New test.
160 * tests/Makefile.am (TESTS): Add it.
161 * unpack.c (build_tree): Report an error if Huffman tree has
163 * unpack.c (unpack): Fix check for EOB.
164 Remove now-unnecessary check for code out of range.
166 2017-09-19 Jim Meyering <meyering@fb.com>
168 maint: fix "make syntax-check": remove useless HAVE_UTIME_H definitions
169 * tailor.h: Don't define HAVE_UTIME_H.
171 maint: avoid "make syntax-check" failure due to old-NEWS modification
172 * cfg.mk (old_NEWS_hash): Update, to reflect recent NEWS correction.
174 2017-09-19 Paul Eggert <eggert@cs.ucla.edu>
176 gzexe: improve usage diagnostic
177 * gzexe.in (usage): Reword for clarity (Bug#28514).
179 misc: update --version copyright
180 * gunzip.in, gzexe.in, gzip.c, zcat.in, zdiff.in, zforce.in, zgrep.in:
181 * zless.in, zmore.in, znew.in: Update copyright year in --version
184 maint: prefer HTTPS to HTTP, FTP in URLs
186 maint: copy bootstrap from Gnulib
188 maint: port to GCC 7.2
189 * configure.ac (WERROR_CFLAGS): Avoid -Wduplicated-branches.
190 * tailor.h (FALLTHROUGH): New macro, taken from Emacs.
191 * gzip.c (main): Use it.
193 maint: update .gitignore for recent Gnulib
195 build: update gnulib submodule to latest
197 2017-05-07 Jim Meyering <meyering@fb.com>
199 maint: also distribute a zip-compressed tarball
200 * configure.ac (AM_INIT_AUTOMAKE): Add dist-zip, for
201 those lacking gzip, 7zip, etc. Suggested by Karl Berry in
202 https://bugs.gnu.org/25538.
204 2017-03-13 Paul Eggert <eggert@cs.ucla.edu>
206 gzip: port zdiff, zless to Busybox
207 Problem reported by Denys Zagorui (Bug#26088).
208 * tests/zdiff: Check that diff uses POSIX-format output.
209 * zless.in (less_version): Don't exit merely because 'less -V'
210 fails; instead, assume 'less' is compatible with an old version of
211 the original 'less'. Busybox 'less -V' fails, but apparently its
212 'less' works anyway somehow.
214 2017-02-06 Jim Meyering <meyering@fb.com>
216 tests: avoid failure when running with no tty
217 * tests/help-version (zcat_setup): Export TERM=dumb, to avoid zless
218 malfunction. Reported by Assaf Gordon in https://bugs.gnu.org/25636#8
220 gnulib: update to latest; and tests/init.sh and bootstrap
222 maint: change "time stamp" to "timestamp" globally
223 This avoids a new syntax-check failure.
224 * ChangeLog-2007: Perform that change.
226 * algorithm.doc: Likewise.
227 * doc/gzip.texi: Likewise.
228 * gunzip.in: Likewise.
232 * m4/.gitignore: Likewise.
233 * sample/ztouch: Likewise.
234 * tests/timestamp: Likewise.
238 * cfg.mk: Update the old news hash accordingly.
240 2017-01-01 Jim Meyering <meyering@fb.com>
242 maint: tweak a distcheck rule
243 * dist-check.mk (my-distcheck): Don't use --disable-nls.
244 That option is now unrecognized.
246 maint: update gnulib and copyright dates for 2017
247 * gnulib: Update to latest.
248 * all files: Run "make update-copyright".
250 2016-11-08 Jim Meyering <meyering@fb.com>
252 maint: use "returns_" rather than explicit comparison with "$?"
253 * tests/zdiff: Use "returns_ 1" rather than testing $? = 1.
254 * tests/hufts: Likewise.
255 * tests/timestamp: Likewise, but s/1/2/.
257 2016-11-04 Paul Eggert <eggert@cs.ucla.edu>
259 gzip: minor time stamp cleanups
260 * NEWS: Document this.
261 * gzip.c (get_method): Do not warn about MTIME out of range.
262 This should avoid useless chatter on hosts with 32-bit time_t
263 after the year 2038 (!).
264 (do_list): Do not pass junk time stamp to localtime.
265 (copy_stat): Do not report "time stamp restored" if restoration
268 gzip: --no-time cleanup
269 Problem reported by Jim Meyering (Bug#24826).
270 * gzip.c (longopts): Remove non-working no-time entry.
271 (help) [UNDOCUMENTED]: Don't document it.
273 gzip --no-name: avoid spurious warning
274 Problem reported by Jim Meyering (Bug#24826).
275 * tests/timestamp: Add a test from Jim Meyering to exercise the fix
276 * zip.c (zip): Treat unknown time stamps as 0.
278 2016-10-24 Jim Meyering <meyering@fb.com>
280 maint: update .gitignore files to ignore more generated files
282 2016-10-02 Jim Meyering <meyering@fb.com>
284 maint: avoid unwarranted "make syntax-check" failure
285 * tests/timestamp: Reorder "rm" arguments so the doubled-word
286 syntax-check rule does not detect a false positive "in in" here.
288 gnulib: update to latest
290 2016-09-07 Paul Eggert <eggert@cs.ucla.edu>
292 * doc/gzip.texi: Fix off-by-one timestamp.
294 2016-09-06 Paul Eggert <eggert@cs.ucla.edu>
296 gzip: fix some Y2038 etc. bugs
297 * NEWS: Document this.
298 * gzip.c (get_method): Warn about out-of-range MTIME,
299 and ignore it instead of relying on possibly-undefined behavior.
300 * tests/Makefile.am (TESTS): Add timestamp.
301 * tests/timestamp: New test.
302 * zip.c (zip): Warn about out-of-range file time stamp.
304 2016-08-29 Jim Meyering <meyering@fb.com>
306 maint: fix gzip-specific syntax-check rule
307 * cfg.mk (sc_gzip_copyright_check): This rule had two problems.
308 It was failing erroneously (the copyright date in gzip.c is fine),
309 yet it was complaining. The first problem is that the rule's
310 diagnostic mentioned the wrong file: lib/version-etc.c, rather than
311 ./gzip.c. The second problem is that it specified this file name
312 via "in_files" rather than the "in_vc_files" variable.
314 2016-06-12 Paul Eggert <eggert@penguin.cs.ucla.edu>
316 gzip: fix port to Atari by not defining ASMV
317 Problem reported by Helmut Karlowski in: http://bugs.gnu.org/23751
318 * tailor.h (ASMV) [ATARI || atarist]: Do not define.
320 2016-06-12 Paul Eggert <eggert@cs.ucla.edu>
322 gzip: drop mentions of Amiga, VMS
323 These platforms were not supported anyway, and their code was
324 suffering from bitrot. This patch may also fix some file name
325 glitches on MS-Windowsish platforms.
326 * bootstrap.conf (gnulib_modules): Add dosname.
327 * gzip.c: Include dosname.h.
328 (shorten_name, treat_dir): Use last_component rather than looking
329 at path separators by hand.
330 * tailor.h: Remove sections on porting to VMS and to Amiga,
331 since dosname.h doesn't support these platforms anyway.
332 (PATH_SEP2, PATH_SEP3, STDC_HEADERS, SUFFIX_SEP, RECORD_IO)
333 (HAVE_CHOWN, HAVE_LSTAT, HAVE_SYS_DIR_H, direct): Remove. All
334 uses removed. Many uses replaced by calls to ISSLASH and/or
337 2016-04-29 Jim Meyering <meyering@fb.com>
339 maint: arrange for better URLs in generated announcement message
340 * cfg.mk (url_dir_list): Define. I had been correcting the generated
341 URLs by hand, just before the announcement. This is better.

355 2016-04-19 Paul Eggert <eggert@cs.ucla.edu>
357 gzip: simplify by closing ourselves
358 This simplifies the previous fix, by avoiding the use of the
359 closein module. That module was problematic, as gzip normally
360 does not use stdio for output and never uses it for input.
361 Also, it is a heavyweight module, as it drags many files into lib
362 (c-ctype.c, c-ctype.h, closein.c, closein.h, closeout.c, closeout.h,
363 close-stream.c, close-stream.h, config.charset, c-strcasecmp.c,
364 c-strcaseeq.h, c-strcase.h, c-strncasecmp.c, fpending.c, fpending.h,
365 freadahead.c, freadahead.h, localcharset.c, localcharset.h, mbrtowc.c,
366 mbsinit.c, quotearg.c, quotearg.h, quote.h, ref-add.sin, ref-del.sin,
367 streq.h, wctype-h.c, wctype.in.h) and into m4 (closein.m4, closeout.m4,
368 close-stream.m4, codeset.m4, configmake.m4, fpending.m4, freadahead.m4,
369 glibc21.m4, localcharset.m4, locale-fr.m4, locale-ja.m4, locale-zh.m4,
370 mbrtowc.m4, mbsinit.m4, mbstate_t.m4, quotearg.m4, wctype_h.m4),
371 and these files are thus no longer needed.
372 * bootstrap.conf (gnulib_modules): Remove closein.
373 * gzip.c: Don't include closein.h.
374 (stdin_was_read): New static var.
375 (main): Don't use close_stdin.
376 Invoke finish_out to exit after outputting via stdio's stdout.
377 Close stdin after reading it.
378 Restore previous way of closing stdout.
379 (treat_stdin): Record that stdin was read.
380 (finish_out): New function.
382 gzip: fix bug with -l output to pipes
383 Problem reported by Christian Franke via Eric Blake in:
384 http://bugs.gnu.org/23314
385 * NEWS: Mention this.
386 * gzip.c (main): Do not close stdout twice when given -l.
387 Instead, -l now just fflushes stdout, so that fdatasync
388 can synchronize it if --synchronize is also specified.
389 * tests/list: New test case.
390 * tests/Makefile.am (TESTS): Add it.
392 2016-03-28 Paul Eggert <eggert@cs.ucla.edu>
394 Port to Oracle Solaris Studio 12.4
395 Problem reported by Kiyoshi KANAZAWA in: http://bugs.gnu.org/23133
396 * NEWS: Document this.
397 * configure.ac (ASMV): Do not define if NO_ASM is
398 anywhere in DEFS; it doesn't need to be surrounded by white space.
399 * lib/match.c: Do not use x86 version if __x86_64__ is defined.

411 2016-03-26 Paul Eggert <eggert@cs.ucla.edu>
414 Problem reported by Assaf Gordon in: http://bugs.gnu.org/23107#13
415 * gzexe.in, zdiff.in, zgrep.in: Don't rely on mktemp -t,
416 as it has a different meaning in NetBSD.
418 * tests/init.sh: Sync from Gnulib.
420 Port to Alpine Linux which uses Busybox
421 * Makefile.am (check-local): Use plain diff rather than
423 2016-03-24 Jim Meyering <meyering@fb.com>
425 gzip: also honor GZIP=--rsyncable
426 * gzip.c (main): Also accept --rsyncable when it is specified
427 via the GZIP environment variable.
428 I noticed this when gzip's "make dist" failed because maint.mk
429 detected that gzip now honors --rsyncable, yet when it set GZIP_ENV
430 to include that, and that propagated via automake-generated code
431 to the GZIP setting used in the "make dist" rule, there, it was not
432 honored, and caused "make dist" to fail.
434 2016-03-21 Paul Eggert <eggert@cs.ucla.edu>
436 Fix typo in previous patch
438 Port to Solaris 11 /bin/sh
439 * m4/shell.m4 (AC_PROG_SHELL): Reject Solaris 11 /bin/sh.
440 A problem was reported by Nelson H. F. Beebe for OpenIndiana.
441 I reproduced a problem with different symptoms on Solaris 11.
442 Switching to Bash fixed it, and I hope this fixes it for
443 OpenIndiana too, since both problems appear to be shell-related.

448 Problem reported by Fulvio Scapin in: http://bugs.gnu.org/22945

451 Adjust a test to cover the case of more than one line in -f's input.

453 a regular file, copy it into a temporary and use the temporary.

457 gzip: port to AIX 7.1 + xlc V12.1
458 * inflate.c, unlzw.c, util.c: Include tailor.h after including any
459 system include file that might in turn include signal.h for the
460 first time, so that SIGPIPE is not #defined to 0 prematurely,
461 which clashes with signal.h's SIGPIPE.

475 as this is clearer anyway, and it pacifies Clang. Problem reported
476 by Assaf Gordon in: http://bugs.gnu.org/22900#40
478 2016-03-06 Jim Meyering <meyering@fb.com>
480 tests: port to systems for which ":" is not the PATH separator
481 * Makefile.am (new_path): New variable.
482 (check-local): Use $(PATH_SEPARATOR) rather than a literal ":",
483 to avoid "make syntax-check" failure.
485 2016-03-06 Paul Eggert <eggert@cs.ucla.edu>
487 doc: minor --rsyncable doc fixes
488 * doc/gzip.texi (Sample): Mention --rsyncable.
489 * gzip.c (help): Sort and do not capitalize the new --rsyncable
492 gzip: minor zgrep cleanup
493 * zgrep.in: Simplify previous change.
495 gzip: port zgrep to Solaris 11.2
496 Problem reported by Assaf Gordon in: http://bugs.gnu.org/22900#11
497 * zgrep.in: Port to Solaris 11.2 /bin/sh (ksh 93u 2011-02-08),
498 where $? is 256+SIG when a process was killed with signal SIG, and
499 where 'exit 257' is equivalent to 'exit 1'. Apparently some other
500 sh implementations use 256+128+SIG. So, instead of using plain
501 'exit $?', use the equivalent of 'exit ((128 * (128 <= $?)) + $? %
502 128)' within the script, and use the equivalent of 'kill -$($? %
503 128)' at the top level if the exit status is 128 or more.
505 gzip: remove --__bindir
506 * NEWS: Document this.
507 * gzexe.in, gunzip.in, zcat.in, zcmp.in, zdiff.in, zegrep.in:
508 * zfgrep.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
509 Remove support for undocumented --__bindir option. Callers can
510 set PATH instead; that's less error-prone. This fixes some
511 'make check' failures on my Solaris 11 box, which occurred
512 because the test scripts were mistakenly testing the installed
513 gzip rather than the gzip in the working directory.
514 * Makefile.am (.in): Don't replace bindir.
515 (check-local): Set PATH instead of using --__bindir.
516 * tests/help-version (gunzip_setuphelp, gzexe_setuphelp)

523 2016-03-04 Jim Meyering <meyering@fb.com>
525 tests: fix "make check" failure on AIX 7.1
526 * tests/Makefile.am (TESTS_ENVIRONMENT): Modernize:
527 remove unused shell_or_perl_ function, and use an

1111 zmore: rewrite to fix bugs and assume POSIX
1112 Problem reported for Solaris 9 by Daniel in
1113 <http://lists.gnu.org/archive/html/bug-gzip/2012-06/msg00007.html>.
1114 Rather than figure out what exactly went wrong in Solaris 9
1115 it was easier to rip out all the buggy compatibility and stty cruft.
1116 * zmore.in: Don't use stty or trap; simply pipe the output to 'more'
1117 and let it deal with signals and terminal control.
1118 Use printf, not 'echo', to avoid problems with backslashes.
1119 Don't assume ANS is not 's' in the environment.
1120 Use a 'more'-style header instead of rolling our own style.
1121 Paginate the header, too; the old behavior lost the header.

1475 is present at the end of the last line. All uses changed.

1484 A script went awry when updating copyright dates in gzip's shell
1485 scripts. It should update comments to look like "# Copyright (C)
1486 2007, 2010 Free Software Foundation, Inc." (with a set of years)
1487 and version messages to look like "Copyright (C) 2010 Free
1488 Software Foundation, Inc." (with just the most-recent year).
1489 Instead, it sometimes ignored one, sometimes the other, and
1490 typically put ranges into version messages. Fix all this stuff by
1491 hand, using dates that I divined from the change logs (so they're
1492 a bit more accurate than script-generated dates). We need to fix
1493 the script before it runs in 2011.

1543 zgrep: fix parsing of -Eh options
1544 * zgrep.in: Update list of single-letter options to match what's
1545 in GNU grep. Add -h as an alias for --no-filename. Bug reported
1546 by Vladimir Sidorenko in
1547 <http://lists.gnu.org/archive/html/bug-gzip/2010-09/msg00007.html>.
1549 2010-08-17 Paul Eggert <eggert@cs.ucla.edu>
1551 gzip: fix NO_SIZE_CHECK for VMS
1552 * gzip.c (do_list): Use if, not #if.
1553 * tailor.h (NO_SIZE_CHECK) [defined(VAXC) || defined(VMS)]: Define.
1554 * zip.c (zip): Simplify conditional, which was incorrect at any rate
1557 2010-08-15 Paul Eggert <eggert@cs.ucla.edu>
1559 algorithm.doc: mention Internet RFC 1952 and modernize a bit
1560 * algorithm.doc: Update to mention header-CRC and Internet RFC 1952.
1561 Also, remove the crypto stuff, which never worked.
1562 Inspired by that same suggestion of Greg Roelofs.
1564 gzip: Use 0x%04x instead of %x when printing 16-bit checksums
1565 * gzip.c (get_method): Use 0x%04x, not %x, to print 16-bit checksums.
1566 Inspired by a suggestion of Greg Roelofs in

1576 gzip: don't assume C99, and don't assume overlapping memcpy should work
1577 * tailor.h (NOMEMCPY): Remove. memcpy is entitled to not work
1578 on overlapping blocks.
1579 * inflate.c (inflate_codes): Don't put decl after statement.
1582 * gzip.c (get_method): don't assume size_t can be printed with %u
1584 2010-07-02 Paul Eggert <eggert@cs.ucla.edu>
1586 Mention that gzip -d now handles FHCRC.
1588 2010-07-02 Paul Eggert <eggert@cs.ucla.edu>

1591 Problem reported by Greg Roelofs in:
1592 http://lists.gnu.org/archive/html/bug-gzip/2010-06/msg00003.html
1594 * gzip.c (discard_input_bytes): New function.
1595 (get_method): Check header checksum, if given. We never generate it,
1596 but other programs may.
1597 * gzip.h (HEADER_CRC): Renamed from CONTINUATION. All uses changed.
1598 * tailor.h [defined __50SERIES]: Remove PRIMOS stuff that was obsolete
1599 anyway and would have made this patch harder to maintain.
1600 (get_char, put_char): Remove.
1601 * zip.c (zip): Use put_byte instead of the now-removed put_char.
1603 2010-07-01 Paul Eggert <eggert@cs.ucla.edu>

1647 * tests/Makefile.am (TESTS_ENVIRONMENT): Export VERSION=$(VERSION).
1649 tests: improve help-version
1650 * tests/help-version: Use fail_, rather than echo+Exit.
1652 tests: pull help-version from grep
1654 build: keep --version strictly up to date
1655 Before this change, in development, gzip's --version output could lag
1656 behind reality by a couple deltas or by a "-dirty" suffix. That would
1657 lead to spurious failure of the new --version-$VERSION PATH cross-check.
1658 * Makefile.am (version.c, version.h): New rules.

1699 tests: arrange for skip and failure notices to go to stderr, not .log
1700 * tests/init.cfg: New file. Make init.sh's stderr_fileno_ match
1701 what the "exec 9>&2" we use in TESTS_ENVIRONMENT.

1712 2010-04-05 Jim Meyering <meyering@redhat.com>
1714 build: use gnulib's lib-ignore module
1715 * bootstrap.conf (gnulib_modules): Add lib-ignore, in case it helps.
1716 * Makefile.am (AM_LDFLAGS): Define it.
1718 maint: let configure-invoked cpp emit diagnostics to config.log
1719 * configure.ac: Do not discard CPP's stderr.
1721 build: update gnulib submodule to latest, and adapt
1722 * cfg.mk: Update to use new _sc_search_regexp interface. Run this:
1723 perl -pi -e 's/\b_prohibit_regexp\b/_sc_search_regexp/;'
1724 -e 's/\bmsg=/halt=/; s/\bre=/prohibit=/;' cfg.mk
1725 and then adjust backslashes so they still line up.
1726 * cfg.mk (local-checks-to-skip): Add new sc_texinfo_acronym, to skip it.
1727 * msdos/tailor.c (fcalloc): Mark a diagnostic for translation, to
1728 placate stricter syntax-check, even though no one uses this file.
1730 use assembly code matcher when possible
1731 * configure.ac (ASCPPPOST): Backslash-escape "#" in AC_SUBST'd
1732 variable, to keep make from seeing it as a comment-introducer.
1733 Based on a patch by Petr Pisar.
1734 * lib/Makefile.am (match.$(OBJEXT)): Use AM_V_GEN and AM_V_at.
1735 * lib/match.c: Don't include <config.h>.
1736 It would impede configure-time assembler test.
1737 * .x-sc_require_config_h: Exempt lib/match.c from syntax-check.
1738 * .x-sc_require_config_h_first: Likewise.
1740 2010-03-20 Jim Meyering <meyering@redhat.com>
1742 do not use stat.st_mtime of a non-regular file
1743 * gzip.c: Include "timespec.h".
1744 (treat_stdin): Use st_mtime only from a regular file.
1745 This matters at least on Cygwin 1.7.1-1, for which a stdin-pipe has
1746 the mtime of /dev/null, rather than the gzip-documented-for-pipes
1747 "current time". Reported by Denis Excoffier.

1751 tests: exercise the fix for the decompression data-loss bug
1752 * tests/null-suffix-clobber: New file.
1753 * Makefile.am (TESTS): Add it.
1755 gzip: fix a data-loss bug when decompressing with --suffix=''
1756 * gzip.c (main): Disallow an empty --suffix=S also with -d.
1757 Otherwise, "gzip -d -S '' F.gz" would ask if it's ok to remove the
1758 existing file, "F.gz"; if you reply "yes", you'd lose all of that data.
1759 Use of an empty suffix was already rejected in compression mode.
1760 * gzip.1 (--suffix (-S)): Do not recommend to use "gunzip -S '' *".
1761 Describe how the suffix is used when decompressing, too.
1762 * NEWS (Bug fixes): mention the fix.
1763 Reported by Ripduman Sohan.
1765 tests: add ---presume-input-tty option, solely for testing
1766 * gzip.c: Include <stdbool.h>.

1778 * Makefile.am (TESTS): Add it.
1780 tests: make distcheck invoke "make syntax-check" and other tests
1781 * dist-check.mk: New file, from coreutils.
1782 * cfg.mk: Include it.
1783 * Makefile.am (distcheck-hook): New rule, to make us use it.
1785 zcmp: consistently indicate failure with exit status of 2
1786 * zcmp.in: Exit with status of 2 (not 1), when writing
1787 --help or --version output fails, to be more like cmp.

1800 2010-02-03 Mark Adler <madler@alumni.caltech.edu>
1802 gzip -cdf now handles concatenation of gzip'd and uncompressed data
1803 * util.c (copy): Change semantics so as to honor a decremented inptr.
1804 * gzip.c (get_method): When needed (-cdf), decrement inptr rather
1805 than clearing it -- and output the first magic byte.
1807 2010-02-03 Dmitry V. Levin <ldv@altlinux.org>
1809 zgrep: terminate gracefully when a pipeline is interrupted by a signal
1810 zgrep is not terminated gracefully when its grep/sed pipeline
1811 is terminated by a signal. For example, a command like
1812 zgrep -F .TH /usr/share/man/man1/*.gz | head
1813 continues working long after the "head" process completes.
1814 Another example, a command like
1815 zgrep unmatched-pattern /usr/share/man/man1/*.gz
1816 cannot be interrupted by sending a SIGQUIT with Ctrl-\ key, it outputs
1817 zgrep: line 221: test: : integer expression expected
1819 * zgrep.in: Terminate gracefully when the grep/sed pipeline is
1820 terminated by a signal.
1821 * tests/zgrep-signal: New test.
1822 * Makefile.am (TESTS): Add it.
1824 2010-02-03 Jim Meyering <meyering@redhat.com>
1826 maint: teach "make syntax-check" the space-only indentation rule

1829 * bootstrap: Remove "indent-tabs-mode: nil" directive.
1830 * .x-sc_prohibit_tab_based_indentation: New file.

1864 tests: begin moving tests into their own files
1865 * Makefile.am (TESTS): Add tests/stdin.
1866 (check-local): Move the stdin check to its own file:
1867 * tests/stdin: New script.
1869 tests: remove unnecessary use of "path_prepend_ ."
1870 It is unnecessary, since Makefile.am's TESTS_ENVIRONMENT setting
1871 already adds the top build directory, and besides, is only
1872 marginally useful when running stand-alone, since it presumes
1873 that the script is being run from the top build directory.
1874 * tests/helin-segv: Remove unnecessary use of path_prepend_.

1915 * NEWS (Bug fixes): Mention it.
1917 maint: avoid a minor "make syntax-check" failure

1919 from an old diagnostic.

1924 build: update gnulib submodule to latest
1926 2010-01-11 Yuxi Zhang <YZhang@qnx.com>
1928 gzip -d: use memcpy more often
1929 * inflate.c (inflate_codes): Use memcpy (rather than slower
1930 memcopy-like code) in more cases.
1932 2010-01-11 Jim Meyering <meyering@redhat.com>
1934 build: do not override gnulib-provided AM_CFLAGS options
1935 Avoid a warning from automake:
1936 lib/Makefile.am:24: AM_CFLAGS multiply defined in condition TRUE ...
1937 lib/gnulib.mk:30: ... `AM_CFLAGS' previously defined here
1938 lib/Makefile.am:20: `lib/gnulib.mk' included from here
1940 * lib/Makefile.am (AM_CFLAGS): Append $(WARN_CFLAGS) and
1941 $(WERROR_CFLAGS), i.e., use "+=", not "=".
1942 This was introduced via 2009-12-17 commit 0341fc22,
1943 "build: with --enable-gcc-warnings, use -Werror",
1944 but fortunately is not a bug, because the definition
1945 it would have overridden was always empty.
1947 2010-01-10 Jim Meyering <meyering@redhat.com>
1949 gzip -d would fail with a CRC error...
1950 ...for some inputs, and some memcpy implementations. It is possible
1951 that an offending input has to be compressed "from FAT filesystem
1952 (MS-DOS, OS/2, NT)", since the sole reproducer no longer evokes a
1953 CRC error when uncompressed and recompressed on a GNU/Linux system.
1954 Also, using an unpatched reverse-memcpy-gzip on over 100,000 inputs
1955 on a GNU/Linux system did not turn up another reproducer.
1956 * inflate.c (inflate_codes): Don't call memcpy with overlapping regions.
1957 Properly detect when source and destination overlap.
1958 * tests/memcpy-abuse: New test, to trigger misbehavior.
1959 * Makefile.am (TESTS): Add it.

2039 build: util.c: avoid warnings about add_envopt
2040 * util.c (add_envopt): The parameter "env" was used for two conflicting

2042 was used as an argument to free, which must not be "const".
2043 Rename the parameter and use a new local variable for the second role.
2045 build: avoid many const-related warnings

2112 build: do not use AC_PREFIX_PROGRAM
2113 * configure.ac: Do not use "AC_PREFIX_PROGRAM(gzip)".
2114 It would induce behavior that is so surprising that it is probably
2115 universally considered to be buggy, these days. Reported by Zube
2116 in http://thread.gmane.org/gmane.comp.gnu.gzip.bugs/273
2118 2009-10-10 Jim Meyering <meyering@redhat.com>

2138 Fail if we don't find a free file descriptor.
2139 (exists): New function; Use it in place of less portable "test -e".
2140 Testing for existence of /dev/fd/$fd doesn't work on Solaris 10,
2141 since all 256 always exist (as char devices), but testing for
2142 /proc/$$/fd/$fd does work, so do that instead.

2144 * tests/zgrep-f: New test; exercise this bug.
2145 * NEWS (Bug fixes): Mention it.

2151 * zgrep.in: When the pattern comes from stdin, redirect it to a
2152 different file descriptor, since we're about to use stdin.
2154 2009-10-09 Jim Meyering <meyering@redhat.com>

2168 zdiff would fail to print differences in two compressed inputs
2169 * zdiff.in: Don't let cmp output mix with echo'd gzip exit
2170 status values. Report and fix from Jörg-Volker Peetz via

2239 Throw in some "GNU"'s.
2240 Make direntries be what we actually want.
2243 2009-09-26 Jim Meyering <meyering@redhat.com>

2247 tests, to exempt them from "make syntax-check".
2249 gzip: don't use an uninitialized file descriptor
