+
+ 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 Oracle Solaris Studio 12.4
+ Problem reported by Kiyoshi KANAZAWA in: http://bugs.gnu.org/23133
+ * NEWS: Document this.
+ * configure.ac (ASMV): Do not define if NO_ASM is
+ anywhere in DEFS; it doesn't need to be surrounded by white space.
+ * lib/match.c: Do not use x86 version if __x86_64__ is defined.

+
+ 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 <meyering@fb.com>
+
+ 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 <eggert@cs.ucla.edu>
+
+ 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.
+
+2016-03-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ zgrep: with -f SPECIAL, read SPECIAL just once
+ Problem reported by Fulvio Scapin in: http://bugs.gnu.org/22945
+ * NEWS: Document this.
+ * tests/zgrep-f: Add a test.
+ Adjust a test to cover the case of more than one line in -f's input.
+ * zgrep.in (with_filename): With -f FILE, if FILE is stdin or not
+ a regular file, copy it into a temporary and use the temporary.
+
+2016-03-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ 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.
+

+
+ gnulib: update to latest
+
+ maint: don't ignore gitlog-to-changelog failure

+ gitlog-to-changelog. This syncs to coreutils' copy of this rule.
+
+2016-03-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ gzip: pacify clang
+ * gzip.c (do_list): Use 2D array of char for month abbreviations,
+ as this is clearer anyway, and it pacifies Clang. Problem reported
+ by Assaf Gordon in: http://bugs.gnu.org/22900#40
+
+2016-03-06 Jim Meyering <meyering@fb.com>
+
+ tests: port to systems for which ":" is not the PATH separator
+ * Makefile.am (new_path): New variable.
+ (check-local): Use $(PATH_SEPARATOR) rather than a literal ":",
+ to avoid "make syntax-check" failure.
+
+2016-03-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ doc: minor --rsyncable doc fixes
+ * doc/gzip.texi (Sample): Mention --rsyncable.
+ * gzip.c (help): Sort and do not capitalize the new --rsyncable
+ help string.
+
+ gzip: minor zgrep cleanup
+ * zgrep.in: Simplify previous change.
+
+ 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.
+ (check-local): Set PATH instead of using --__bindir.
+ * tests/help-version (gunzip_setuphelp, gzexe_setuphelp)
+ (zcat_setuphelp, zcmp_setuphelp, zdiff_setuphelp)
+ (zegrep_setuphelp, zfgrep_setuphelp, zforce_setuphelp)

+ (znew_setuphelp): Remove. All uses removed.
+ (lbracket_setup): Default args to empty.
+
+2016-03-04 Jim Meyering <meyering@fb.com>
+
+ tests: fix "make check" failure on AIX 7.1
+ * tests/Makefile.am (TESTS_ENVIRONMENT): Modernize:
+ remove unused shell_or_perl_ function, and use an
+ export_with_values function as grep does, to remove
+ a lot of duplication.

+ * lib/.gitignore, m4/.gitignore: Add new gnulib files.

+ section, as this stuff would not work anyway now, and circa 2001
+ Apple stopped supporting Mac OS 9 and earlier.
+ * zip.c: Do not include unistd.h and fcntl.h, as this file does
+ not directly use any symbols defined by those headers.

Compilers and Options

Documentation and other data files still use the regular prefix.

-kinds of files. Run `configure --help' for a list of the directories

The most portable way to affect installation locations is to pass the

both of the following shortcuts of passing variable assignments to the

having to reconfigure or recompile.
The first method involves providing an override variable for each

prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
-`${prefix}'. Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated. The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.

- The second method involves providing the `DESTDIR' variable. For

-`/alternate/directory' before all installation names. The approach of

GNU gzip NEWS -*- outline -*-
+* Noteworthy changes in release 1.8 (2016-04-26) [stable]
+
+** Bug fixes
+
+ gzip -l no longer falsely reports a write error when writing to a pipe.
+ [bug introduced in gzip-1.7]
+
+ Port to Oracle Solaris Studio 12 on x86-64.
+ [bug present since at least gzip-1.2.4]
+
+ When configuring gzip, ./configure DEFS='...-DNO_ASM...' now
+ suppresses assembler again. [bug introduced in gzip-1.3.5]
+
+
+* Noteworthy changes in release 1.7 (2016-03-27) [stable]
+
+** Changes in behavior
+
+ The GZIP environment variable is now obsolescent; gzip now warns if
+ it is used, and rejects attempts to use dangerous options or operands.
+ You can use an alias or script instead.
+
+ Installed programs like 'zgrep' now use the PATH environment variable
+ as usual to find subsidiary programs like 'gzip' and 'grep'.
+ Previously they prepended the installation directory to the PATH,
+ which sometimes caused 'make check' to test the wrong gzip executable.
+ [bug introduced in gzip-1.3.13]
+
+** New features
+
+ gzip now accepts the --synchronous option, which causes it to use
+ fsync and similar primitives to transfer output data to the output
+ file's storage device when the file system supports this. Although
+ this option makes gzip safer in the presence of system crashes, it
+ can make gzip considerably slower.
+
+ gzip now accepts the --rsyncable option. This option is accepted in
+ all modes, but has effect only when compressing: it makes the resulting
+ output more amenable to efficient use of rsync. For example, when a
+ large input file gets a small change, a gzip --rsyncable image of
+ that file will remain largely unchanged, too. Without --rsyncable,
+ even a tiny change in the input could result in a totally different
+ gzip-compressed output file.
+
+** Bug fixes
+
+ gzip -k -v no longer reports that files are replaced.
+ [bug present since the beginning]
+
+ zgrep -f A B C no longer reads A more than once if A is not a regular file.
+ This better supports invocations like 'zgrep -f <(COMMAND) B C' in Bash.
+ [bug introduced in gzip-1.2]
+
+
* Noteworthy changes in release 1.6 (2013-06-09) [stable]

-`gzip' reduces the size of the named files using Lempel-Ziv coding
+‘gzip’ reduces the size of the named files using Lempel–Ziv coding
(LZ77). Whenever possible, each file is replaced by one with the
-extension `.gz', while keeping the same ownership modes, access and
-modification times. (The default extension is `-gz' for VMS, `z' for
-MSDOS, OS/2 FAT and Atari.) If no files are specified or if a file
-name is "-", the standard input is compressed to the standard output.
-`gzip' will only attempt to compress regular files. In particular, it
-will ignore symbolic links.
-
- If the new file name is too long for its file system, `gzip'
-truncates it. `gzip' attempts to truncate only the parts of the file
-name longer than 3 characters. (A part is delimited by dots.) If the
-name consists of small parts only, the longest parts are truncated.
-For example, if file names are limited to 14 characters, gzip.msdos.exe
-is compressed to gzi.msd.exe.gz. Names are not truncated on systems
-which do not have a limit on file name length.
-
- By default, `gzip' keeps the original file name and time stamp in
-the compressed file. These are used when decompressing the file with
-the `-N' option. This is useful when the compressed file name was
-truncated or when the time stamp was not preserved after a file
-transfer. However, due to limitations in the current `gzip' file
-format, fractional seconds are discarded. Also, time stamps must fall
-within the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15 UTC,
-and hosts whose operating systems use 32-bit time stamps are further
-restricted to time stamps no later than 2038-01-19 03:14:07 UTC. The
-upper bounds assume the typical case where leap seconds are ignored.
-
- Compressed files can be restored to their original form using `gzip
--d' or `gunzip' or `zcat'. If the original name saved in the
-compressed file is not suitable for its file system, a new name is
-constructed from the original one to make it legal.
-
- `gunzip' takes a list of files on its command line and replaces each
-file whose name ends with `.gz', `.z' `-gz', `-z', or `_z' (ignoring

+file whose name ends with ‘.gz’, ‘.z’ ‘-gz’, ‘-z’, or ‘_z’ (ignoring
case) and which begins with the correct magic number with an
-uncompressed file without the original extension. `gunzip' also
-recognizes the special extensions `.tgz' and `.taz' as shorthands for
-`.tar.gz' and `.tar.Z' respectively. When compressing, `gzip' uses the
-`.tgz' extension if necessary instead of truncating a file with a `.tar'

- `gunzip' can currently decompress files created by `gzip', `zip',

-When using the first two formats, `gunzip' checks a 32 bit CRC (cyclic
-redundancy check). For `pack', `gunzip' checks the uncompressed
-length. The `compress' format was not designed to allow consistency
-checks. However `gunzip' is sometimes able to detect a bad `.Z' file.
-If you get an error when uncompressing a `.Z' file, do not assume that
-the `.Z' file is correct simply because the standard `uncompress' does
-not complain. This generally means that the standard `uncompress' does

+Multiple compressed files can be concatenated. In this case, ‘gunzip’
will extract all members at once. If one member is damaged, other

decompressed and then recompressed in a single step.

-`gzip'. These options are interpreted first and can be overwritten by
-explicit command line parameters. For example:
+The obsolescent environment variable ‘GZIP’ can hold a set of default
+options for ‘gzip’. These options are interpreted first and can be

+‘gzip’.
- for sh: GZIP="-8v --name"; export GZIP
- for csh: setenv GZIP "-8v --name"
- for MSDOS: set GZIP=-8v --name

+this can cause problems when using scripts, this feature is supported
+only for options that are reasonably likely to not cause too much
+harm, and @command{gzip} warns if it is used. This feature will be
+removed in a future release of @command{gzip}.
+
+You can use an alias or script instead. For example, if
+@command{gzip} is in the directory @samp{/usr/bin} you can prepend
+@file{$HOME/bin} to your @env{PATH} and create an executable script
+@file{$HOME/bin/gzip} containing the following:
@example
-for sh: GZIP="-8v --name"; export GZIP
-for csh: setenv GZIP "-8v --name"
-for MSDOS: set GZIP=-8v --name

+export PATH=/usr/bin
+exec gzip -9 "$@@"

@chapter Using @command{gzip} on tapes
the whole block is passed to @command{gunzip} for decompression,
@command{gunzip} detects that there is extra trailing garbage after the
compressed data and emits a warning by default if the garbage contains
-nonzero bytes. You have to use the

-@env{GZIP} environment variable, as in:
-

+ 1m--rsyncable0m
+ When you synchronize a compressed file between two computers,
+ this option allows rsync to transfer only files that were
+ changed in the archive instead of the entire archive. Normally,
+ after a change is made to any file in the archive, the compres-
+ sion algorithm can generate a new version of the archive that
+ does not match the previous version of the archive. In this
+ case, rsync transfers the entire new version of the archive to
+ the remote computer. With this option, rsync can transfer only
+ the changed files as well as a small amount of metadata that is
+ required to update the archive structure in the area that was
+ changed.
+
1mADVANCED USAGE0m
Multiple compressed files can be concatenated. In this case, 4mgunzip0m
will extract all members at once. For example:
ently. gzip is designed as a complement to tar, not as a replacement.
1mENVIRONMENT0m
- The environment variable 1mGZIP 22mcan hold a set of default options for
- 4mgzip24m. These options are interpreted first and can be overwritten by
- explicit command line parameters. For example:
- for sh: GZIP="-8v --name"; export GZIP
- for csh: setenv GZIP "-8v --name"
- for MSDOS: set GZIP=-8v --name
+ The obsolescent environment variable 1mGZIP 22mcan hold a set of default
+ options for 4mgzip24m. These options are interpreted first and can be over-
+ written by explicit command line parameters. As this can cause prob-
+ lems when using scripts, this feature is supported only for options
+ that are reasonably likely to not cause too much harm, and 4mgzip24m warns
+ if it is used. This feature will be removed in a future release of
+ 4mgzip24m.
+
+ You can use an alias or script instead. For example, if 4mgzip24m is in the
+ directory 1m/usr/bin 22myou can prepend 1m$HOME/bin 22mto your 1mPATH 22mand create an
+ executable script 1m$HOME/bin/gzip 22mcontaining the following:
- On Vax/VMS, the name of the environment variable is GZIP_OPT, to avoid
- a conflict with the symbol set for invocation of the program.
+ #! /bin/sh
+ export PATH=/usr/bin
+ exec gzip -9 "$@"
+
+ On VMS, the name of the obsolescent environment variable is GZIP_OPT,
+ to avoid a conflict with the symbol set for invocation of the program.

pad the output with zeroes up to a block boundary. When the data is
read and the whole block is passed to 4mgunzip24m for decompression, 4mgunzip0m
detects that there is extra trailing garbage after the compressed data
- and emits a warning by default. You have to use the --quiet option to
- suppress the warning. This option can be set in the 1mGZIP 22menvironment
- variable as in:
- for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0
- for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0
-
- In the above example, gzip is invoked implicitly by the -z option of
- GNU tar. Make sure that the same block size (-b option of tar) is used
- for reading and writing compressed data on tapes. (This example
- assumes you are using the GNU version of tar.)
+ and emits a warning by default. You can use the --quiet option to sup-
+ press the warning.
1mBUGS0m
The gzip format represents the input size modulo 2^32, so the --list
4mpress24m compresses better than 4mgzip24m.

- than stdin, stdout, and stderr before exiting, since the call to

- # Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is
- # useless:
- # - It returns the empty string when LANG is set to a locale of the
- # form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
- # LC_CTYPE file.
- # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
- # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
- # - The documentation says:
- # "... all code that calls BSD system routines should ensure
- # that the const *char parameters of these routines are in UTF-8
- # encoding. All BSD system functions expect their string
- # parameters to be in UTF-8 encoding and nothing else."
- # It also says
- # "An additional caveat is that string parameters for files,
- # paths, and other file-system entities must be in canonical
- # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
- # characters are decomposed ..."
- # but this is not true: You can pass non-decomposed UTF-8 strings
- # to file system functions, and it is the OS which will convert
- # them to decomposed UTF-8 before accessing the file system.
- # - The Apple Terminal application displays UTF-8 by default.
- # - However, other applications are free to use different encodings:
- # - xterm uses ISO-8859-1 by default.
- # - TextEdit uses MacRoman by default.
- # We prefer UTF-8 over decomposed UTF-8-MAC because one should
- # minimize the use of decomposed Unicode. Unfortunately, through the
- # Darwin file system, decomposed UTF-8 strings are leaked into user
- # space nevertheless.
- # Then there are also the locales with encodings other than US-ASCII
- # and UTF-8. These locales can be occasionally useful to users (e.g.
- # when grepping through ISO-8859-1 encoded text files), when all their
- # file names are in US-ASCII.
