version 1.9
* NEWS: Record release date.
2018-01-06 Paul Eggert <[email protected]>
gzexe: port to macOS mktemp
Problem reported by Jeffrey Walton (Bug#30000).
* gzexe.in, zdiff.in, zgrep.in:
Don’t assume that mktemp works when given no arguments,
as this is not true for macOS. Instead, use a syntax
that should work with coreutils, NetBSD, and macOS.
While we’re in the neighborhood, be more consistent about how program
names are used in temporary file names. Also, watch out for TMPDIR
values that are not absolute file names, since they can cause problems
(e.g., leading "-").
2018-01-03 Jim Meyering <[email protected]>
maint: update gnulib and copyright dates for 2018
* gnulib: Update to latest.
* bootstrap: Update from gnulib.
* all files: Run "make update-copyright".
2017-12-16 Jim Meyering <[email protected]>
build: update gnulib to latest
2017-11-24 Paul Eggert <[email protected]>
maint: zforce and zmore exit status cleanup
Problem reported by Nelson H. F. Beebe.
* zforce.in, zmore.in: On failure, exit with status 1 instead of
with whatever failing status that printf or mv exited with.
2017-11-23 Paul Eggert <[email protected]>
gzexe: ensure file always exists
* gzexe.in: When in a filesystem that does not support symlinks,
use rm+cp rather than mv to make backups, so that the argument
file always exists.
2017-11-23 Jim Meyering <[email protected]>
build: update gnulib to latest
2017-11-16 Jim Meyering <[email protected]>
gzexe: work even without the ability to make a hard link
* gzexe.in: When ln -f fails to create a "~"-style backup,
fall back to using mv -f.
Reported by Bruno Haible in http://debbugs.gnu.org/29266
2017-11-15 Jim Meyering <[email protected]>
build: make each generated script unwritable
* Makefile.am (.in): Ensure that each generated script is unwritable.
This makes it less likely that someone (even me) will mistakenly
modify one of those generated files.
2017-11-13 Jim Meyering <[email protected]>
zless, znew: exit 1 upon --help or --version write failure
* zless.in: Exit 1 upon --help or --version write error.
* znew.in: Likewise.
2017-11-12 Paul Eggert <[email protected]>
maint: script diagnostics status cleanup
Problem reported by Bruno Haible (Bug#29266#20).
* NEWS: Mention this.
* gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zforce.in:
* zgrep.in, zless.in, zmore.in, znew.in:
Use printf instead of echo if the argument might contain ‘\’, at
least in theory. Don’t assume printf exits with status 1 on
failure; it might be some other positive status.
* gzexe.in: Use printf consistently instead of echo, and
proscribe it instead of echo.
tests: don’t be so strict about timestamps
* tests/timestamp: We’ve had many false alarms about timestamps
that are not gzip problems, but instead are problems with ‘touch’.
Attempt to work around them by not trusting ‘touch’ so much.
Problems and parts of solutions proposed by Bruno Haible.
2017-11-10 Paul Eggert <[email protected]>
build: update gnulib submodule to latest
2017-11-09 Jim Meyering <[email protected]>
gnulib: update to latest
maint: use noreturn, not ATTRIBUTE_NORETURN
Use gnulib's stdnoreturn module so we can include
<stdnoreturn.h> and the "noreturn" helper macro, thus
replacing the definition and uses of ATTRIBUTE_NORETURN.
* bootstrap.conf (gnulib_modules): Add stdnoreturn.
* gzip.h (ATTRIBUTE_NORETURN): Remove definition.
Include stdnoreturn.h and use "noreturn" for each
ATTRIBUTE_NORETURN-adorned function declaration.
* gzip.c (do_exit, try_help): Use "noreturn".
tests: unpack-invalid: correct and clean up a test
* tests/unpack-invalid: There was a logic error that would have
caused this test to ignore a failure if first iteration of the
loop set fail=1 and the second one reset it to 0. Also, use
"returns_ 1 ...", to require an exit status of 1.
2017-11-07 Paul Eggert <[email protected]>
gzip: diagnose out-of-range MTIME
This seems to be the problem reported by Bruno Haible for GNU/Hurd
i386 with touch 8.26 and glibc 2.24 (Bug#29033#20).
* NEWS: Document this.
* gzip.c (get_method): If MTIME is out of range for
this platform, warn and substitute the nearest in-range
value, instead of silently ignoring it.
(do_list): Remove no-longer-needed test for unknown time stamp.
2017-11-06 Paul Eggert <[email protected]>
misc: diagnose year-2038 configuration problems
* bootstrap.conf (gnulib_modules): Add year2038.
* m4/.gitignore: Add year2038.m4[
maint: remove IMPORT_FROM_GETTEXT
* bootstrap.conf (IMPORT_FROM_GETTEXT): Remove.
This is a relic from older Gnulib, and has no effect now.
2017-10-29 Jim Meyering <[email protected]>
tests/unpack-valid: port to printf that do not grok hex
Many versions of printf do not handle hexadecimal in a format string,
so this test would fail.
* tests/init.cfg (hex_printf_): Copied from grep's tests/init.cfg.
* tests/unpack-valid: Use hex_printf_.
Reported by Bruno Haible in https://bugs.gnu.org/29033#26
gnulib: update to latest; also update tests/init.sh from gnulib
gzip: fix bug with any upper case custom ('-S'-specified) suffix
Any user-specified suffix with an upper case
letter would fail to match desired file.
* gzip.c (get_suffix): First, arrange to have only one return
point rather than two. Put a lower-cased (just-malloc'd) copy
of z_suffix in the suffix vector, and free it before returning.
* tests/upper-suffix: New file.
* tests/Makefile.am (TESTS): Add it.
* NEWS: Mention it.
Reported by [email protected] in https://bugs.gnu.org/29006
2017-10-16 Paul Eggert <[email protected]>
gzip: fix bug in unpack EOB check
Problem reported by Vidar Holen (Bug#28861).
* NEWS: Mention fix.
* tests/unpack-valid: New test.
* tests/Makefile.am (TESTS): Add it.
* unpack.c (build_tree): Report an error if Huffman tree has
too few leaves.
* unpack.c (unpack): Fix check for EOB.
Remove now-unnecessary check for code out of range.
2017-09-19 Jim Meyering <[email protected]>
maint: fix "make syntax-check": remove useless HAVE_UTIME_H definitions
* tailor.h: Don't define HAVE_UTIME_H.
maint: avoid "make syntax-check" failure due to old-NEWS modification
* cfg.mk (old_NEWS_hash): Update, to reflect recent NEWS correction.
2017-09-19 Paul Eggert <[email protected]>
gzexe: improve usage diagnostic
* gzexe.in (usage): Reword for clarity (Bug#28514).
misc: update --version copyright
* gunzip.in, gzexe.in, gzip.c, zcat.in, zdiff.in, zforce.in, zgrep.in:
* zless.in, zmore.in, znew.in: Update copyright year in --version

Problem reported by Denys Zagorui (Bug#26088).
* tests/zdiff: Check that diff uses POSIX-format output.
* zless.in (less_version): Don't exit merely because 'less -V'

maint: fix gzip-specific syntax-check rule
* cfg.mk (sc_gzip_copyright_check): This rule had two problems.
It was failing erroneously (the copyright date in gzip.c is fine),
yet it was complaining. The first problem is that the rule's
diagnostic mentioned the wrong file: lib/version-etc.c, rather than
./gzip.c. The second problem is that it specified this file name
via "in_files" rather than the "in_vc_files" variable.

gzip: drop mentions of Amiga, VMS
These platforms were not supported anyway, and their code was
suffering from bitrot. This patch may also fix some file name
glitches on MS-Windowsish platforms.
* bootstrap.conf (gnulib_modules): Add dosname.
* gzip.c: Include dosname.h.
(shorten_name, treat_dir): Use last_component rather than looking
at path separators by hand.
* tailor.h: Remove sections on porting to VMS and to Amiga,
since dosname.h doesn't support these platforms anyway.
(PATH_SEP2, PATH_SEP3, STDC_HEADERS, SUFFIX_SEP, RECORD_IO)
(HAVE_CHOWN, HAVE_LSTAT, HAVE_SYS_DIR_H, direct): Remove. All

gzip: simplify by closing ourselves
This simplifies the previous fix, by avoiding the use of the
closein module. That module was problematic, as gzip normally
does not use stdio for output and never uses it for input.
Also, it is a heavyweight module, as it drags many files into lib
(c-ctype.c, c-ctype.h, closein.c, closein.h, closeout.c, closeout.h,
close-stream.c, close-stream.h, config.charset, c-strcasecmp.c,
c-strcaseeq.h, c-strcase.h, c-strncasecmp.c, fpending.c, fpending.h,
freadahead.c, freadahead.h, localcharset.c, localcharset.h, mbrtowc.c,
mbsinit.c, quotearg.c, quotearg.h, quote.h, ref-add.sin, ref-del.sin,
streq.h, wctype-h.c, wctype.in.h) and into m4 (closein.m4, closeout.m4,
close-stream.m4, codeset.m4, configmake.m4, fpending.m4, freadahead.m4,
glibc21.m4, localcharset.m4, locale-fr.m4, locale-ja.m4, locale-zh.m4,
mbrtowc.m4, mbsinit.m4, mbstate_t.m4, quotearg.m4, wctype_h.m4),
and these files are thus no longer needed.
* bootstrap.conf (gnulib_modules): Remove closein.
* gzip.c: Don't include closein.h.
(stdin_was_read): New static var.
(main): Don't use close_stdin.
Invoke finish_out to exit after outputting via stdio's stdout.
Close stdin after reading it.
Restore previous way of closing stdout.
(treat_stdin): Record that stdin was read.
(finish_out): New function.
gzip: fix bug with -l output to pipes
Problem reported by Christian Franke via Eric Blake in:
http://bugs.gnu.org/23314
* NEWS: Mention this.
* gzip.c (main): Do not close stdout twice when given -l.
Instead, -l now just fflushes stdout, so that fdatasync
can synchronize it if --synchronize is also specified.
* tests/list: New test case.
* tests/Makefile.am (TESTS): Add it.

Port to NetBSD 7.0
Problem reported by Assaf Gordon in: http://bugs.gnu.org/23107#13
* gzexe.in, zdiff.in, zgrep.in: Don't rely on mktemp -t,
as it has a different meaning in NetBSD.
* tests/init.sh: Sync from Gnulib.
Port to Alpine Linux which uses Busybox
* Makefile.am (check-local): Use plain diff rather than
2016-03-24 Jim Meyering <[email protected]>
gzip: also honor GZIP=--rsyncable
* gzip.c (main): Also accept --rsyncable when it is specified
via the GZIP environment variable.
I noticed this when gzip's "make dist" failed because maint.mk
detected that gzip now honors --rsyncable, yet when it set GZIP_ENV
to include that, and that propagated via automake-generated code
to the GZIP setting used in the "make dist" rule, there, it was not
honored, and caused "make dist" to fail.
2016-03-21 Paul Eggert <[email protected]>
Fix typo in previous patch
Port to Solaris 11 /bin/sh
* m4/shell.m4 (AC_PROG_SHELL): Reject Solaris 11 /bin/sh.
A problem was reported by Nelson H. F. Beebe for OpenIndiana.
I reproduced a problem with different symptoms on Solaris 11.
Switching to Bash fixed it, and I hope this fixes it for
OpenIndiana too, since both problems appear to be shell-related.

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

gzip: port zgrep to Solaris 11.2
Problem reported by Assaf Gordon in: http://bugs.gnu.org/22900#11
* zgrep.in: Port to Solaris 11.2 /bin/sh (ksh 93u 2011-02-08),
where $? is 256+SIG when a process was killed with signal SIG, and
where 'exit 257' is equivalent to 'exit 1'. Apparently some other
sh implementations use 256+128+SIG. So, instead of using plain
'exit $?', use the equivalent of 'exit ((128 * (128 <= $?)) + $? %
128)' within the script, and use the equivalent of 'kill -$($? %
128)' at the top level if the exit status is 128 or more.
gzip: remove --__bindir
* NEWS: Document this.
* gzexe.in, gunzip.in, zcat.in, zcmp.in, zdiff.in, zegrep.in:
* zfgrep.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
Remove support for undocumented --__bindir option. Callers can
set PATH instead; that's less error-prone. This fixes some
'make check' failures on my Solaris 11 box, which occurred
because the test scripts were mistakenly testing the installed
gzip rather than the gzip in the working directory.
* Makefile.am (.in): Don't replace bindir.

I.e., on systems that let users give files away.
* gzip.c (do_chown): New function.
(copy_stat): Use it, to change the group, then the permissions,
then the owner. Idea suggested by Vladimir Marek in
<http://bugs.gnu.org/15672#11>

znew: avoid denial-of-service issue
Reported by Rich Burridge in <http://bugs.gnu.org/15522>.
* znew.in: Rewrite to avoid the need for a temporary file in /tmp.
That way, we avoid the need for set -C
and worrying about denial of service.
Use touch -r and chmod --reference rather than cpmod.
Assume cp -p works, as it's now universal.
Quote 'echo' args better, while we're at it.
(warn, tmp, cpmod, cpmodarg): Remove.
(GZIP): Unset, so that we needn't test for gzip extension.
(ext): Now always '.gz'.
* znew.1: Document the change of implementation assumptions.

Fix spelling typo in newly-added comment.
tests: zgrep-signal race condition fix
* tests/zgrep-signal: Check that Perl supports dup2.
(exec_with_SIGPIPE_SIGDFL): Remove.
(write_to_dangling_pipe): Simplify by moving more of it into Perl.
Fix race condition, where subcommand writes to a pipe before the ":"
command exits. Problem reported by Thorsten Glaser in
<http://lists.gnu.org/archive/html/bug-gzip/2013-06/msg00028.html>.

zgrep: usage should say which grep options are not supported
* zgrep.in (usage): Document which grep options are not supported.
Problem reported by Liron Paryente in
<http://lists.gnu.org/archive/html/bug-grep/2013-06/msg00005.html>.

gzip: port util.c to Compaq C V6.5-303
* util.c (crc_32_tab): Move definition to front, since this
compiler doesn't allow declarations of static arrays with
incomplete types. Problem reported by Steven M. Schweda in
<http://lists.gnu.org/archive/html/bug-gzip/2013-06/msg00010.html>.
tests: zgrep-context assumes grep knows context
* tests/Makefile.am (TESTS_ENVIRONMENT): Pass GREP too.
* tests/zgrep-context: Check that the underlying grep supports
context options. Problem reported by Steven M. Schweda in
<http://lists.gnu.org/archive/html/bug-gzip/2013-06/msg00010.html>.
doc: zgrep exit status, unsupported options
* zgrep.1 (EXIT STATUS, BUGS): New sections.
Problem reported by Bdale Garbee in
<http://lists.gnu.org/archive/html/bug-gzip/2013-06/msg00007.html>.
maint: port to platforms lacking SIGPIPE
* tailor.h (SIGPIPE): Define to 0 if not defined. This fixes a
porting bug introduced as part of 2012-11-16 syntax-check cleanup.
Problem reported by Bdale Garbee in
<http://lists.gnu.org/archive/html/bug-gzip/2013-06/msg00006.html>.

build: avoid automake warning that suggests use of subdir-objects
* configure.ac (AM_INIT_AUTOMAKE): Use the subdir-objects option.
build: avoid warning about deprecated use of automake's ACLOCAL_AMFLAGS
* Makefile.am (ACLOCAL_AMFLAGS): Don't use this deprecated variable.
* configure.ac: Do this instead: AC_CONFIG_MACRO_DIR([m4]).
build: use more portable shell syntax in search of working shell
* m4/shell.m4: Adjust sh/case syntax not to evoke a syntax
error from Solaris 10's /bin/sh.
build: update gnulib to latest, and bootstrap
2013-05-28 Jim Meyering <[email protected]>
tests: exercise the new --keep option
* tests/keep: New file.
* tests/Makefile.am (TESTS): Add it.
2013-05-28 Rodrigo Campos <[email protected]>
gzip: add "--keep" option to retain (don't delete) input files
gzip now accepts the --keep (-k) option, for consistency with tools
like xz, lzip and bzip2. With this option, gzip no longer removes
named input files when compressing and decompressing.
* doc/gzip.texi: Document it.
* gzip.1: Likewise.
* gunzip.in: Likewise.
* NEWS: Likewise.
* gzip.c: Add support for "--keep".

tests: redo patch for non-GNU gzip installed in /usr/local/bin
Problem with previous patch reported by Antonio Diaz Diaz in
<http://lists.gnu.org/archive/html/bug-gzip/2013-04/msg00011.html>.
* tests/help-version (gunzip_setuphelp, gzexe_setuphelp)
(zcat_setuphelp, zcmp_setuphelp, zdiff_setuphelp)
(zegrep_setuphelp, zfgrep_setuphelp, zforce_setuphelp)
(zgrep_setuphelp, zless_setuphelp, zmore_setuphelp)
(znew_setuphelp): New functions, used when testing even --help.
(zdiff_setup, zcat_setup, znew_setup, zgrep_setup, gzexe_setup):
Use gzip_setuphelp to set --__bindir.

tests: work even if non-GNU gzip is installed in /usr/local/bin
Problem reported by Antonio Diaz Diaz in
<http://lists.gnu.org/archive/html/bug-gzip/2013-04/msg00004.html>.
* tests/help-version (zdiff_setup, zcat_setup, znew_setup, zgrep_setup)
(gzexe_setup): Pass --__bindir so that subsidiary programs are our
own's, not /usr/local/bin's. This requires using 'eval' on the result.
(zcmp_setup, gunzip_setup, zmore_setup, zless_setup, zforce_setup)
(zegrep_setup, zfgrep_setup): Invoke one of the other setup functions,
to make the patterns more obvious and simplify future maintenance.
* zcmp.in, zegrep.in, zfgrep.in: Pass __bindir to subsidiary program.
maint: adjust to Gnulib, Automake changes
* .gitignore: Add *.trs.
* lib/.gitignore: Add unused-parameter.h.
tests: port to Solaris 10 /bin/sh
* tests/Makefile.am (TESTS_ENVIRONMENT):
Use "FOO=val; export FOO" rather than "export FOO=val",
as the latter form doesn't work with Solaris /bin/sh.

gzip: port to DMF file systems
* util.c (read_buffer): When reading a file with O_NONBLOCK, if
the read fails with errno==EAGAIN, clear O_NONBLOCK and try again.
Problem reported by Vitezslav Cizek in
<http://lists.gnu.org/archive/html/bug-gzip/2013-02/msg00030.html>.
