Paul Eggert 79c3261c8b * m4/shell.m4 (AC_PROG_SHELL): Check for old-fashioned shells that 
don't allow "(" in front of case labels.  Problem reported by midair
in <http://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00004.html>.
Also, check for buggy shells that require ";;" before "esac".

don't allow "(" in front of case labels. Problem reported by midair
in <http://lists.gnu.org/archive/html/bug-gzip/2007-04/msg00004.html>.
Also, check for buggy shells that require ";;" before "esac".
2007-04-13 Paul Eggert <eggert@cs.ucla.edu>

* configure.ac (AC_INIT): Likewise.
* README: Update year in copyright notice.
* m4/shell.m4: Add copyright notice.
* bootstrap (gnulib_tool_option_extras): Put this back; it was
inadvertently omitted from gnulib.
(gnulib_tool_option): Use it.
* .cvsignore: Add *._bootmp*.
* lib/.cvsignore: Add stdlib.h, stdlib_.h, time.h, time_.h, unistd.h.
Remove alloca.c, alloca.h, alloca_.h, exit.h, getdelim.c, getdelim.h,
getline.c, getline.h, malloc.c, mbchar.c, mbchar.h, mbuiter.h, memchr.c,
regcomp.c, regex.c, regex.h, regex_internal.c, regex_internal.h,

longlong.m4, mbchar.m4, mbiter.m4, mbrtowc.m4, memchr.m4, regex.m4,
rpmatch.m4, ssize_t.m4, stdint.m4 strcase.m4, timespec.m4, ulonglong.m4,
wchar_t.m4, wcwidth.m4, wint_t.m4.
2007-03-29 Paul Eggert <eggert@cs.ucla.edu> (tiny change)
* znew.in (tmp): Use $TMPDIR as temp directory, if given.
Suggested by Juan Manuel Guerrero.
2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
* README-hacking: New file, renamed from README-cvs.
* README-cvs: Remove.
* bootstrap: Sync from today's gnulib.
* bootstrap.conf (gnulib_modules): Add 'time'.
* gzip.c: Don't include timespec.h; 'time' fixes time.h for that.
* zip.c: Likewise.
* gzip.c: Don't include time.h or sys/time.h; gzip.h now includes
time.h, which is now enough.
* gzip.h: Include <time.h>.
2007-03-14 Paul Eggert <eggert@cs.ucla.edu>
* README (WARNING): Reword to avoid mention of no-longer-existing
section in INSTALL file. Problem reported by Paul Townsend in
<http://lists.gnu.org/archive/html/bug-gzip/2007-03/msg00000.html>.
2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
* gzip.c (foreground): Initialize to zero. This doesn't fix a bug
since C guarantees it's zero, but it's more consistent with the
rest of the code. Problem reported by Mark Adler.
2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
* zdiff.in: Don't use '((' in a shell script, as it's not portable
to some ksh implementations, e.g., Solaris 10 ksh M-11/16/88i.
Problem reported by Nelson H. F. Beebe in
<http://lists.gnu.org/archive/html/bug-gzip/2007-02/msg00005.html>.
2007-02-05 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Version 1.3.11 released.
* configure.ac (AC_INIT): Likewise.
* doc/gzip.texi: Convert Texinfo format into a more modern style.
Put in current output samples.
* .cvsignore: Add *.gz, gunzip, zcat, zcmp, zegrep, zfgrep.
* lib/.cvsignore: Add sys_time_.h, unistd_.h.
* m4/.cvsignore: Add gnulib-common.m4, sys_time_h.m4.
* gunzip.in, zcat.in, zcmp.in, zegrep.in, zfgrep.in: New files.
* 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.
2007-01-10 Paul Eggert <eggert@cs.ucla.edu>
* m4/shell.m4 (AC_PROG_SHELL): Test that $(...) works.
Problem reported for SGI IRIX 6 by Nelson H. F. Beebe in
<http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00007.html>.
2007-01-04 Paul Eggert <eggert@cs.ucla.edu>
* zdiff.in (cmp0): New var.
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.
2007-01-03 Paul Eggert <eggert@cs.ucla.edu>
* zdiff.in: Test /dev//fd/3, not /dev/fd/3, to work around a problem
with Tru64 4.0F ksh M-11/16/88f reported by Thomas Koutcher in
<http://lists.gnu.org/archive/html/bug-gzip/2007-01/msg00000.html>.
2006-12-30 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Version 1.3.10 released.
* configure.ac (AC_INIT): Likewise.
* Makefile.am (check-local): Don't assume $(srcdir) is '.'.
(MAINTAINERCLEANFILES): Move gzip.doc.gz from here ...
(MOSTLYCLEANFILES): ... to here.
2006-12-29 Paul Eggert <eggert@cs.ucla.edu>
* zless.in: Work around a bug in less 394 and earlier; it
mishandles $%=~ in file names. Problem reported by
Sami Liedes in <http://bugs.debian.org/383358>.
* doc/gzip.texi: Swap order of dircategory entries, to pacify
Debian install-info 1.10.28. This should fix
<http://bugs.debian.org/404048>.
* zgrep.in (version): Fix bug: $grep wasn't evaluated.
* zgrep.in: Rewrite to make the option processing more
compatible with GNU and POSIX grep. Assume POSIX shell
for more stuff, since we're already assuming that.
* Makefile.am (check-local): Check zgrep -iV.
2006-12-26 Paul Eggert <eggert@cs.ucla.edu>
Fix Debian bug 367673 <http://bugs.debian.org/367673> plus several
other bugs discovered in the neighborhood.
* NEWS: gzip -q now exits with status 2 (not 1) on SIGPIPE.
zgrep has many bugs fixed with argument handling, special characters,
and exit status.
* gzip.c (abort_gzip_signal): Implement gzip -q change.
* zgrep.in: Implement zgrep change.
2006-12-23 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Fix bug reported by Martin Mares in
<http://bugs.debian.org/177942>.
* gzip.c (treat_stdin): Remove NO_STDIN_FSTAT and NO_PIPE_TIMESTAMP
stuff. It didn't work (led to syntax errors) and was confusing.
Report an error if stdin cannot be statted even if !list && no_time.
Get stdin's size if it is regular.
(treat_file): Do not report an error with setuid, setgid,
sticky, or non-regular, non-directory files if to_stdout.
Allow 'force' to override the caution about sticky files.
Use the same form for time stamps that treat_stdin uses.
* zdiff.in: Fix typo that broke most usages. Problem reported by
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.
* NEWS: Document this.
* Makefile.am (gzip.doc.gz): New rule.
(check-local): Depend on it, and test zdiff for Debian bug 404114.
2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
* zdiff.1: Mention that these programs currently understand only
formats that gzip does. Problem reported by Jari Aalto in
<http://bugs.debian.org/404099>.
2006-12-20 Paul Eggert <eggert@cs.ucla.edu>
* inflate.c (huft_build): Fix regression that caused gzip to
refuse to uncompress null input (all zero length codes). Problem
reported by Yiorgos Adamopoulos. This regression was caused by
the security patch installed 2006-11-20, which in turn came from
Debian, which in turn apparently came from Thomas Biege of SuSe.
2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
* NEWS, configure.ac (AC_INIT):
Version 1.3.9 released.
* Makefile.am (MOSTLYCLEANFILES): Add _match.i.
* configure.ac (for an assembler syntax supported by this package):
Remove _match.i.
* bootstrap (gnulib_tool_options_extras): New var.
(gnulib_tool_options): Use it.
* bootstrap.conf (gnulib_tool_options_extras): Avoid getline and
rpmatch. gzip doesn't need them, since it doesn't ENABLE_NLS.
2006-12-13 Bruno Haible <bruno@clisp.org>
* configure.ac: Use $CPPFLAGS everywhere $CPP is used, and use
$CPPFLAGS $CFLAGS everywhere $CC is used.
* lib/Makefile.am (match.$(OBJEXT)): Likewise.
* configure.ac: Test the exit code of the $CPP and $ASCPPPOST commands
separately.
2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
* configure.ac (ASCPPPOST): Simplify to use just 'sed'.
* lib/Makefile.am (match.$(OBJEXT)): Check for CPP failure.
2006-12-11 Bruno Haible <bruno@clisp.org>
Cross-compilation support.
* configure.ac (ASCPP): Remove substituted variable.
(ASCPPPOST, ASCPPFLAGS): New substituted variables.
* lib/Makefile.am (ASCPP, LN_S): Remove unnecessary macro definitions.
(match.$(OBJEXT)): Use CPP, ASCPPFLAGS, ASCPPPOST instead of ASCPP.
* configure.ac: Add test for chown function.
* gzip.c (treat_file) [!HAVE_CHOWN]: Don't call chown.
* gzip.c: Include "timespec.h". This doesn't fix any bugs, but
it is clearer.
2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
The SSIZE_MAX fix didn't work on NSK, so fix it in a more-reliable
(albeit more-complicated) way. Problem reported by Matthew Woehlke.
* gzip.h (read_buffer): New decl.
* unlzw.c (unlzw): Use read_buffer rather than read.
* zip.c (file_read): Likewise.
* util.c (copy, fill_inbuf): Likewise.
(read_buffer, write_buffer): New functions.
(write_buf): Use write_buffer rather than write.
Undo the previous SSIZE_MAX-related change; it didn't work.
* gzip.c: Include <limits.h>.
* util.c: Likewise.
* gzip.h: Don't include <limits.h>.
(INBUFSIZ): Don't worry about SSIZE_MAX here.
2006-12-08 Paul Eggert <eggert@cs.ucla.edu>
* NEWS, configure.ac (AC_INIT):
Version 1.3.8 released.
* gzexe.in (mktemp_status): New var, used to see whether
mktemp is a known command. Use this instead of confounding
mktemp's existence with its success.
* zdiff.in: Remove first line containing ":". This follows
up on the SEDCMD fix of 2006-12-01.
* zforce.in: Likewise.
* zgrep.in: Likewise.
* zless.in: Likewise.
* zmore.in: Likewise.
* znew.in: Likewise.
Fix problems in porting to NSK reported by Matthew Woehlke in
<http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00025.html> and
<http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00027.html>.
* gzip.h: Include <limits.h>, for SSIZE_MAX.
(INBUFSIZE): Don't make it any larger than SSIZE_MAX.
Problem reported by Matthew Woehlke in
<http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
* gzip.c: Don't include <limits.h>, as gzip.h now does this.
* util.c: Likewise.
* gzip.c (main): Set exiting_signal before installing signal handlers.
(install_signal_handlers): Don't set exiting_signal here. This
fixes a C99ism.
* zip.c: Include timespec.h, for time_stamp type.
2006-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
* gzexe.in: Work around FreeBSD shell trap bug.
* gzip.1: Fix typo.
* doc/gzip.texi: Likewise.
2006-12-08 Paul Eggert <eggert@cs.ucla.edu>
* .cvsignore: Add .deps, gzexe, gzip, zdiff, zforce, zgrep,
zless, zmore, znew.
* doc/.cvsignore: Add Makefile.
* lib/.cvsignore: Add .deps, Makefile, alloca.h, config.h, fcntl.h,
stamp-h1, stdint.h, sys.
* configure.ac (for assembler): Set ASFLAGS_config to
-Wa,--noexecstack if this seems advisable on this platform.
Problem reported by Mike Frysinger in
<http://lists.gnu.org/archive/html/bug-gzip/2006-12/msg00018.html>.
* lib/Makefile.am (match.$(OBJEXT)): Use ASFLAGS_config.
2006-12-07 Paul Eggert <eggert@cs.ucla.edu>
* Makefile.am (install-exec-hook): Fix bug when installing
symbolic links as aliases. Problem reported by Mike Frysinger.
* deflate.c (deflate_fast, deflate): Avoid core dump. Problem
originally reported by Jochen Friedrich and trivial patch supplied
by Anthony Towns; see <http://bugs.debian.org/184057>.
2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
* NEWS, configure.ac (AC_INIT):
Version 1.3.7 released.
2006-12-06 Bruno Haible <bruno@clisp.org> (tiny change)
and Paul Eggert <eggert@cs.ucla.edu>
Fix build failure on case-insensitive file systems.
* configure.ac: Use match_.s instead of _match.s.
* Makefile.am (MOSTLYCLEANFILES): Likewise.
* lib/Makefile.am (match.$(OBJEXT)): Likewise.
(MOSTLYCLEANFILES): Likewise.
2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Document the fixes below.
* configure.ac (AC_CHECK_FUNCS_ONCE): Add siginterrupt.
* gzip.c (lstat) [!defined(HAVE_LSTAT) && !defined(lstat)]: Remove.
(SA_NOCLDSTOP, sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
New macros.
(siginterrupt) [!defined SA_NOCLDSTOP && ! HAVE_SIGINTERRUPT]:
New macro.
(HAVE_WORKING_O_NOFOLLOW): Define to 0 if not defined.
(caught_signals, exiting_signal, remove_ofname_fd): New vars.
(remove_ofname): Remove; all uses changed to remove_ofname_fd.
(same_file, name_too_long): Remove.
(install_signal_handlers): New function. It prefers sigaction,
which is more reliable in the presence of race conditions.
Catch SIGXCPU and SIGXFSZ, too.
(main): Use it instead of installing them by hand.
(treat_file): Check for read error when closing ifd.
(treat_file, create_outfile, remove_output_file):
Avoid race conditions with signals.
(create_outfile, check_ofname): Remove most of the gorp about
working around ENAMETOOLONG deficiencies. It's obsolete now, and
anyway it had race conditions. Just rely on O_EXCL and
ENAMETOOLONG. The worst that can happen is that a file name will
be silently truncated on an obsolete machine, but no data will be lost.
(open_and_stat): Use HAVE_WORKING_O_NOFOLLOW rather than O_NOFOLLOW
to work around some O_NOFOLLOW bugs. Otherwise, fall back on
lstat only if lstat is available, as symlinks don't exist otherwise.
(open_input_file): Use O_NONBLOCK and O_NOCTTY too, to avoid
hanging gzip on special files.
(abort_gzip_signal): If sigaction is not available, ignore
signals. If we get the exiting signal, exit with ERROR status
rather than raising a signal.
* tailor.h (NO_ST_INO): Remove; no longer used now that same_file
is gone.
2006-12-05 Paul Eggert <eggert@cs.ucla.edu>
Port to Tandem NSK/OSS, which lacks fchdir. Problem reported by
Matthew Woehlke in
<http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00013.html>.
* bootstrap.conf (gnulib_modules): Remove openat, as it pulls in
fchdir.
* configure.ac: Check for fdopendir.
* gzip.c: Don't include openat.h; no longer needed.
(treat_dir) [!HAVE_FDOPENDIR]: Fall back on the old opendir method
since fdopendir is not available.
2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Describe the following change briefly.
* bootstrap.conf (gnulib_modules): Remove stat-macros; no longer
needed.
* gzip.c: Don't include stat-macros.h; no longer needed.
(treat_file): Refuse to compress files that are setuid, or setgid,
as this can in theory lead to security holes. Also, refuse to
compress files with the sticky bit set, on general principle.
(copy_stat): Don't copy the setuid, setgid, or sticky bits,
as (given the above change) they'll always be zero here.
Invoke chmod before chown, to close a race condition.
* .cvsignore: Add *.doc, build-aux.
* doc/.cvignore: New file.
* lib/.cvsignore: New file.
* m4/.cvsignore: New file.
2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
* doc/gzip.texi (Overview): Mention limits of gzip format's
time stamps. Also, gzip doesn't always preserve time stamps.
* gzip.c (abort_gzip_signal): Don't call abort () as a "safeguard",
since it actually causes a core dump. Problem reported by
Jakub Bogusz.
* NEWS: Describe gzexe changes noted below.
* Makefile.am (.in): Don't bother with SEDCMD. This stuff isn't needed
any more (the hosts it caters to are long extinct), and was
questionable anyway since the code assumes the skip= line was line 2.
* configure.ac (AC_SYS_INTERPRETER, SEDCMD): Remove; no longer needed.
* gzexe.in: Sweep the code and fix some bugs.
My, what sharp teeth you have, gzexe!
The straw that broke this camel's back was Matthew Burgess's bug report
<http://lists.gnu.org/archive/html/bug-gzip/2006-11/msg00012.html>.
(IFS): Set it to the standard value, both here and in the
script gzexe generates.
Check for missing operand after parsing options, not before.
This fixes the case for "cpexe --".
Check for tail -n problem separately in gzexe and in the executable
it generates, in case it's a different 'tail'.
(trap): Remove $tmp only if $tmp is not the empty string.
Preserve exit status.
Don't use the nonstandard (and rarely available) "cpmod" utility.
Don't use "set -C"; it's no longer useful and it breaks things
in some cases.
(main loop): Handle file names beginning with "-".
Exit with status of failing program, not with 1.
Fix some bugs in printing diagnostics, and in quoting.
Require the skip= line to have at least one digit.
Use test -u and test -g rather than using the (less-reliable) ls.
Refuse to compress more programs, e.g., sh.
Use mktemp rather than tempfile. Build a copy of
the compressed or uncompressed executable in the same
directory as the executable, as that's less likely to go wrong
if disk space is low. Have the executable exit with status 127,
not 1, if the decompression process fails; this is more compatible
with meta-programs like nohup. Have the executable
uncompress to a temp file with the same basename as the executable;
this is more likely to go right. Fix a race condition where the
executable temporarily did not exist (in either old or new forms).
Check for race conditions better when mv fails. Do not attempt
to use cp to do the real work, only to copy permissions to a temp
file, since we don't want to trash running executables.
2006-11-26 Paul Eggert <eggert@cs.ucla.edu>
* inflate.c (inflate_dynamic, inflate): Don't send output to
stderr unless DEBUG is defined and 'verbose'. Problem reported by
Santiago Vila.
* zgrep.in: If the file name contains newline, &, \, or |, escape
the character so that 'sed' doesn't mishandle it as a replacement.
Problem reported by Bdale Garbee.
2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
* gzip.1 (OPTIONS): ouput -> output. Problem reported by Matt
Taggart.
* vms/gzip.hlp: Likewise.
* Makefile.am (FILES_TO_CHECK): New macro.
(check-local): Check only the files in FILES_TO_CHECK, since some
files under the working directory might be mutating as the test is
run, e.g., with "make check >log". Problem reported by Jim
Meyering.
2006-11-20 Paul Eggert <eggert@cs.ucla.edu>

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.

(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.

* zless.1, zless.in: Use LESSOPEN, not PAGER.
Suggested by <antos@MAST.queensu.ca>.
2002-09-28 Paul Eggert <eggert@twinsun.com>
* zforce.in: Use shell pattern matching instead of 'expr', which
mishandles names like "+". Remove old check for 14-byte file
names on hosts with broken "mv" implementations, as such systems
aren't in use any more and it's better nowadays to support file
names longer than 14 bytes. Rely on "mv"'s error-reporting.

with some other bugs.
Remove dangling output symlinks properly.
Bug reported by Kalle Olavi Niemitalo.

(NEXTBYTE): Use it.
(inflate_dynamic, inflate_block): Add a local variable w, needed
