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".

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 chown before chmod, 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".
