* maint: update --version copyright datesPaul Eggert2022-04-071-1/+1
| | | | | | | | | | * cfg.mk (srcdirslash): New macro. (in_vc_files): Use it to avoid problems when srcdir is '.'. Also look for copyright dates in shell script *.in files, so that ‘zgrep --version’ etc. outputs current dates. * gunzip.in, gzexe.in, gzip.c, zcat.in, zcmp.in, zdiff.in: * zforce.in, zgrep.in, zless.in, zmore.in, znew.in: Update copyright date in --version output to 2022.
* maint: use C locale more oftenPaul Eggert2022-04-071-2/+2
| | | | | | | | * gzexe.in, zdiff.in, zgrep.in: Run expr and sed in the C locale when it might help to avoid undefined behavior on non-GNU platforms. * sample/zfile, znew.in: Run in the C locale, for simplicity and to avoid undefined behavior on non-GNU platforms.
* build: support --program-prefix etc.Paul Eggert2022-04-041-8/+8
| | | | | | | | | | | | | | | | Problem reported by Antonio Diaz Diaz via Dagobert Michelsen in: https://bugs.gnu.org/16876 * Makefile.am (.in): Substitute for 'gzip', 'zdiff', 'zgrep'. ($(GZIP_TRANSFORMED), $(ZDIFF_TRANSFORMED), $(ZGREP_TRANSFORMED)): New rules to build forwarding shell scripts, if needed. Add these files to BUILT_SOURCES and MOSTLY_CLEANFILES if needed. * configure.ac (GZIP_TRANSFORMED, ZDIFF_TRANSFORMED, ZGREP_TRANSFORMED): New substituted vars. (GZIP_IS_TRANSFORMED, ZDIFF_IS_TRANSFORMED, ZGREP_IS_TRANSFORMED): New Automake conditions. * gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zegrep.in: * zfgrep.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in: Quote possibly-transformed subcommand names.
* zdiff: fix another arg-handling bugPaul Eggert2022-03-081-52/+75
| | | | | Also allow args after file names. Problem reported by Lv Ying <https://bugs.gnu.org/54290#12>.
* zdiff: fix arg handling bugPaul Eggert2022-03-071-1/+10
| | | | | Problem reported by Lv Ying (Bug#54291). * zdiff.in (escape): Handle args like '-C 5'.

* maint: update all copyright dates via "make update-copyright"Jim Meyering2019-01-011-1/+1
| | | | * gnulib: Also update submodule for its copyright updates.
* misc: update --version copyrightPaul Eggert2018-01-151-1/+1
| | | | | | | * 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 output to 2018. This part of the year-number update isn’t automated yet.
* gzexe: port to macOS mktempPaul Eggert2018-01-061-3/+8
| | | | | | | | | | | | 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 "-").
* maint: update gnulib and copyright dates for 2018Jim Meyering2018-01-031-1/+1
| | | | | | * gnulib: Update to latest. * bootstrap: Update from gnulib. * all files: Run "make update-copyright".
* maint: script diagnostics status cleanupPaul Eggert2017-11-121-4/+5
| | | | | | | | | | | | 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.
* misc: update --version copyrightPaul Eggert2017-09-191-1/+1
| | | | | | * 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 output to 2017.

* maint: update gnulib and copyright dates for 2017Jim Meyering2017-01-011-1/+1
| | | | | * gnulib: Update to latest. * all files: Run "make update-copyright".
* Port to NetBSD 7.0Paul Eggert2016-03-261-2/+2
| | | | | | 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.
* gzip: remove --__bindirPaul Eggert2016-03-061-6/+0
| | | | | | | | | | | | | | | | | | | * 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) (zgrep_setuphelp, zless_setuphelp, zmore_setuphelp) (znew_setuphelp): Remove. All uses removed. (lbracket_setup): Default args to empty.
* misc: update --version copyrightPaul Eggert2016-02-281-1/+1
| | | | | | * gunzip.in, gzexe.in, zcat.in, zdiff.in, zforce.in, zgrep.in: * zless.in, zmore.in, znew.in: Update copyright year in --version output to 2016.
* maint: update copyright year, bootstrap, init.shJim Meyering2016-01-011-2/+1
| | | | | | | | | Run "make update-copyright" and then... * gzip.c: Transform the copyright notice via s/2015/2016/. * gnulib: Update to latest. * tests/init.sh: Update from gnulib. * bootstrap: Likewise.
* maint: adjust copyright notices in *.in files to be consistentJim Meyering2015-08-241-1/+2
| | | | | | | | | | | | | | | | The copyright year ranges in *.in files were not being updated, because of a missing ", Inc." suffix. Add that, run run "make udpate-copyright", and ensure 2010..2015 year ranges are covered. * gunzip.in: Update copyright notice and year ranges. * gzexe.in: Likewise. * zcat.in: Likewise. * zdiff.in: Likewise. * zforce.in: Likewise. * zgrep.in: Likewise. * zless.in: Likewise. * zmore.in: Likewise. * znew.in: Likewise.
* maint: update copyright year ranges to include 2015; update gnulibJim Meyering2015-01-011-1/+1

| | | | Run "make update-copyright".
* maint: update all copyright year number rangesJim Meyering2012-01-011-1/+1
| | | | Run "make update-copyright".
* maint: update copyright year ranges to include 2011Jim Meyering2011-01-031-1/+1
| | | | Run "make update-copyright", so "make syntax-check" works in 2011.
* maint: fix copyright dates that were munged by a maintenance scriptPaul Eggert2010-11-081-1/+1
| | | | | | | | | | | | | | | * gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zforce.in: * zgrep.in, zless.in, zmore.in, znew.in: A script went awry when updating copyright dates in gzip's shell scripts. It should update comments to look like "# Copyright (C) 2007, 2010 Free Software Foundation, Inc." (with a set of years) and version messages to look like "Copyright (C) 2010 Free Software Foundation, Inc." (with just the most-recent year). Instead, it sometimes ignored one, sometimes the other, and typically put ranges into version messages. Fix all this stuff by hand, using dates that I divined from the change logs (so they're a bit more accurate than script-generated dates). We need to fix the script before it runs in 2011.

* zdiff would exit 2 (error) rather than 1 for differencesJim Meyering2009-10-091-0/+2
| | | | | | | | | | | | * zdiff.in: Save and restore cmp's exit status around a case statement that would otherwise clobber its value. * NEWS (Bug fixes): Mention it. * tests/zdiff: New test; exercise both bugs. * tests/test-lib.sh: New file. From coreutils. * Makefile.am (EXTRA_DIST): Add tests/test-lib.sh. (TESTS): Add tests/zdiff. (TESTS_ENVIRONMENT): Define. From coreutils. (EXTRA_DIST): Append all $(TESTS).
* zdiff: fix malfunction when operating on two gzip'd inputsJim Meyering2009-10-091-2/+2
| | | | | | | | zdiff would fail to print differences in two compressed inputs * zdiff.in: Don't let cmp output mix with echo'd gzip exit status values. Report and fix from Jörg-Volker Peetz via <http://bugs.debian.org/434275> * NEWS (Bug fixes): Mention it.
* maint: update existing copyright year lists to include 2009Jim Meyering2009-09-261-1/+1

* * Makefile.am (.in): Substitute @bindir@, not BINDIR, forPaul Eggert2007-05-041-1/+5
| | | | | | | | | | | | | | | consistency with other substitutions. (check-local): Use --__bindir . rather than setting GZIP_BINDIR=., to allay security concerns voiced by Joerg Lehners in <http://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00003.html>. * gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zegrep.in, zfgrep.in: * zforce.in, zgrep.in, zless.in, zmore.in, znew.in: Support --__bindir rather than GZIP_BINDIR. * gunzip.in, zcat.in, zcmp.in: Support --help and --version directly, to avoid some confusion in help and version output. Problem reported by Eric Blake in <http://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00006.html>.
* * zdiff.in: Don't use '((' in a shell script, as it's not portablePaul Eggert2007-02-081-1/+1

* * gunzip.in, zcat.in, zcmp.in, zegrep.in, zfgrep.in: New files.Paul Eggert2007-02-051-35/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Makefile.am (EXTRA_DIST): Add them. (bin_SCRIPTS, MOSTLYCLEANFILES): Add gunzip, zcat, zcmp, zdgrep, zfgrep. (.in): Use GZIP_BINDIR as the location of gzip binaries, if it is set. (check-local): Use GZIP_BINDIR. (install-exec-hook, remove-installed-links): Make 'uncompress' an alias for gunzip. * gzexe.1: At least one arg is required. Don't give cat as an example, since gzexe refuses to compress cat due to a bootstrapping issue. List more utilities in this category. * gzexe.in, zdiff.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in: Report our name in usage. * gzexe.in: Don't compress bash. Don't use rmdir, so it's OK to compress rmdir. * gzip.c: Now requires that you compile with -DGNU_STANDARD=0 to get non GNU-standard behavior. We now build with GNU-standard behavior by default, so that programs do not depend on the names of their executables. * zdiff.in: Don't depend on the name of the executable, as per GNU standard. Instead, rely on an internal --__cmp option. Support ' in options. Check for failures in subsidiary gzip invocations. * zgrep.1: Clarify compression issues. * zgrep.in: Don't assume POSIX-style case syntax. Remove unused var have_optarg. * zless.1: zless sets LESSMETACHARS now.
* * zdiff.in (cmp0): New var.Paul Eggert2007-01-041-4/+9
| | | | | | | Rewrite test for /dev/fd/3 to detect bugs in Solaris 8 /bin/bash 2.03. Problem reported by Nelson H. F. Beebe in <http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00001.html>. Avoid "for file; do", which doesn't work with Solaris 8 /bin/sh.
* * zdiff.in: Test /dev//fd/3, not /dev/fd/3, to work around a problemPaul Eggert2007-01-041-1/+3

* * zdiff.in: Fix typo that broke most usages. Problem reported byPaul Eggert2006-12-241-26/+48
| | | | | | | | | | | | | | Jari Aalto in <http://bugs.debian.org/404114>. While we're at it, fix a bunch of other problems. Handle "-" better. Send diagnostics to stderr, not stdout. Use expr rather than echo | sed, to handle special characters better. Report a diagnostic in the 1-arg case, if the argument doesn't end in .gz or the like, rather than having incomprehensible behavior. Do not require that the inputs be regular files. Avoid creating a temporary entirely, if /dev/fd works. If not, then resist denial-of-service attacks better, by using mktemp. * Makefile.am (gzip.doc.gz): New rule. (check-local): Depend on it, and test zdiff for Debian bug 404114.
* * zdiff.in: Remove first line containing ":". This followsPaul Eggert2006-12-091-1/+0

Add Sverre Jarp. * TODO: Add new tasks to remove porting cruft and all those buggy scripts. * configure.ac: Renamed from configure.in. (AC_PREREQ): Bump to 2.60. (AC_INIT): Bump version to 1.3.6. (AC_CONFIG_AUX_DIR): New. (AC_CONFIG_HEADERS): Move config.h to lib. Input is now lib/config.hin. (AM_INIT_AUTOMAKE): Add gnits, dist-shar. (AC_PROG_CC_STDC): New, replacing AC_PROG_CC. (AM_PROG_CC_C_O, AC_PROG_RANLIB): New. (AC_AIX, AC_GNU_SOURCE, AC_MINIX): Remove; gnulib does them now. (gl_EARLY, gl_INIT): New. match.c was moved to lib/match.c. (AC_CHECK_HEADERS_ONCE): Replace AC_CHECK_HEADERS. Don't check for sys/utime.h or utime.h. (AC_CHECK_FUNCS_ONCE): Replace AC_CHECK_FUNCS. Check for fchmod and fchown, not utime. (AC_REPLACE_FUNCS): Remove; rpmatch is now done by gnulib. (AC_CONFIG_FILES): Add doc/Makefile, lib/Makefile. * bits.c: Use the more-usual form for copyright notices in source code. * deflate.c: Likewise. * gzip.c: Likewise. * gzip.h: Likewise. * inflate.c: Likewise. * lzw.h: Likewise. * revision.h: Likewise. * tailor.h: Likewise. * trees.c: Likewise. * unpack.c: Likewise. * unzip.c: Likewise. * util.c: Likewise. * crypt.c (dummy): Add decl so that pedantic compilers won't complain about an empty file. * gzip.c (license_msg): Use more-modern wording. Include fcntl-safer.h, openat.h, stat-macros.h, stat-time.h. Simply include <dirent.h> if !NO_DIR, removing a rats-nest of #ifdefs. Simply include <utimens.h> if !defined NO_UTIME, removing a another rats-nest of #ifdefs. (DIR_OPT, TIME_OPT): Remove. (_D_EXACT_NAMLEN): Renamed from NAMLEN. All uses changed. (S_ISDIR, S_ISREG, O_BINARY, O_CREAT, O_EXCL, S_IRUSR, S_IWUSR): Remove; gnulib now does this. (RETSIGTYPE): Remove; Autoconf does this. (program_name): Renamed from progname, for compatibility with gnulib. All uses changed. (time_stamp): Now struct timespec, not time_t. All uses changd. (remove_oftime): Now volatile. (reset_times): Remove; now done by futimens. (usage): Remove. (try_help): New function. (help, license): Don't output date as part of version. A version number suffices. (help): Redo help message to match style of coreutils etc. (version): Don't bother printing compile-time configuration info like STDC_HEADERS. (main): Don't assume strlen (argv[0]) < INT_MAX (!). On usage errors, suggest --help without outputting all the help. (main, do_list): Remove unnecessary casts. (treat_stdin, treat_file, get_method, copy_stat): Support sub-second time stamp resolution. (treat_file, copy_istat): Close some race conditions if files are renamed as we read or write them. (treat_file): Do not attempt to reset the access times of directories that we read. (open_and_stat, open_input_file): New functions. (do_stat, get_istat): Remove; most of the contents went to these new functions. (make_ofname): Don't use WARN, as it affects exit status. (get_method): When the original file name was truncated, restore from its base name, not from its full name. (do_list): Avoid undefined behavior with out-of-range time stamps. ctime, for example, cannot be invoked on arbitrary time stamps safely, since it might overrun an internal buffer. Do not assume that localtime succeeds. (copy_stat): Do not remove input file; that's now the caller's responsibility. This avoids a problem if there is a write error when the caller closes the output file. (treat_dir): New arg FD, to avoid a race condition. All uses changed. (remove_output_file): New function. (abort_gzip): Use it. (abort_gzip_signal): New function, which is async-signal-safe.

(add_envopt): Use xstrdup instead of xmalloc+strcpy. Use xcalloc rather than calloc + check. (gzip_error): Renamed from error, so we don't collide with gnulib. All uses changed. (xalloc_die): New function. (xmalloc): Remove; no longer needed. * zip.c (zip): Watch for time stamp overflow; the old code mishandled negative time stamps. * gzexe.in: Add support for --help, --version, --.
