+
+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.

+
+2007-03-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README (WARNING): Reword to avoid mention of no-longer-existing

+
+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>.

+ (.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.

+ 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>.

+
+2006-12-29 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.

+
+2006-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)

+ Problem reported by Mike Frysinger in

+
+2006-12-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Makefile.am (install-exec-hook): Fix bug when installing

+
+2006-12-06 Paul Eggert <eggert@cs.ucla.edu>

+
+2006-12-06 Bruno Haible <bruno@clisp.org> (tiny change)

+ * 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

+ run, e.g., with "make check >log". Problem reported by Jim
+ Meyering.

+ 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.
+ Exit with the signal that we got.
+ * gzip.h (program_name, time_stamp, abort_gzip): Adjust decls to
+ match gzip.c changes.
+ * inflate.c (huft_build): Return 2 if null input.
+ * tailor.h (HAVE_UTIME): Do not define; gnulib does this now.
+ (OPEN): Use open_safer, not plain open.
+ * unlzh.c (NPT): Set to 1<<TBIT, not to the maximum of NT and NP.
+ (make_table): Report an error if 1<<tablebits < nextcode.
+ (read_pt_len): Report an error if 16 < c.
+ * unpack.c (read_tree): Report an error if the tree has too many
+ leaves while reading it. Fix off-by-one error in final check.
+ * util.c: Include <xalloc.h>, for xalloc_die decl.
+ (gzip_base_name): Renamed from base_name, so we don't collide
+ with gnulib. All uses changed.
+ (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, --.
+ Don't call basename or sed if we can avoid it.
+ * zdiff.in: Likewise.
+ * zforce.in: Likewise.
+ * zgrep.in: Likewise.
+ * zless.in: Likewise.
+ * zmore.in: Likewise.
+ * znew.in: Likewise.
+ * zdiff.in: Protect against file names beginning with "-".
+ * zmore.in: Likewise.
+ * zgrep.in: Use printf rather than echo, to avoid problems with
+ leading "-" and backslash. Return status of subsidiary grep.
+ * zless.in: Add copyright notice.
+
+ * zless.1: We now pass "--" to LESSOPEN.
+ (BUGS): Mention that input file arguments are required.
+ Add copyright notice.
+
+ * COPYING: Update to current version.
+
+ * Makefile.am (SUBDIRS): New macro.
+ (AUTOMAKE_OPTIONS): Remove; now done in configure.ac.
+ (M4DIR, ACINCLUDE_INPUTS): Remove.
+ (EXTRA_DIST): Remove getopt.h.
+ (gzip_SOURCES): Remove getopt.c, getopt1.c, yesno.c.
+ (gzip_LDADD): Change from @LIBOBJS@ to lib/libgzip.a.
+ (AM_MAKEINFOFLAGS, info_TEXINFOS, gzip_TEXINFOS, ASCPP, LN_S):
+ (match.$(OBJEXT)): Move to subdirectory makefiles.
+ (.in): Substitute @VERSION@, too.
+ (check-local): New rule.
+ (MOSTLYCLEANFILES): Add _match.S.
+
+ * doc/gzip.texi: Renamed from gzip.texi. Change to GNU FDL
+ without invariant sections or cover texts. Don't put
+ version number or date into sample gzip -h output.
+ * lib/match.c: Renamed from match.c. Add ia64 version
+ written by Sverre Jarp (HP Labs).
+
+ * INSTALL: Remove from CVS; now created automatically by
+ the bootstrap script.
