+
+ version 1.10
+ * NEWS: Record release date.
+
+2018-12-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ build: enable -Wunreachable-code
+ * configure.ac (nw): Remove -Wunreachable-code from the list of
+ disabled warnings, now that all offending statements have been removed.
+
+ maint: remove unreachable code
+ Problem reported by Oracle Developer Studio 12.6.
+ In the old days we needed a return statement at the end of
+ the gzip main function to pacify traditional 'lint', but
+ lint checkers nowadays are smarter.
+ * gzip.c (main):
+ * zip.c (file_read): Remove unreachable code.
+
+2018-12-23 Jim Meyering <meyering@fb.com>
+
+ maint: use a slightly cleaner expression
+ * gzip.c (do_list): Simplify an expression:
+ - int positive_off_t_width = INT_BUFSIZE_BOUND (off_t) - 2;
+ + int positive_off_t_width = INT_STRLEN_BOUND (off_t) - 1;
+
+2018-12-22 Jim Meyering <meyering@fb.com>
+
+ build: avoid build failure with --enable-gcc-warnings and latest gcc
+ * gzip.c (do_list): There was a loop to compute the maximum width
+ of a decimal positive off_t value. Replace it with assignment to a
+ constant. Noticed because gcc 9.0.0 20181219 warned about its use
+ as a printf format-width value.
+ (OFF_T_MAX): Remove now-unused definition.
+
+2018-12-21 Jim Meyering <meyering@fb.com>
+
+ maint: improve a comment
+ * trees.c (flush_block): Fix grammar/spelling in a comment.
+
+ maint: update gnulib to latest; also update bootstrap and init.sh
+
+ build: make the autoconf-2.63 requirement explicit
+ * configure.ac: AC_PREREQ: Require 2.63, not 2.59.
+ Autoconf-2.63 has been required for some time via gnulib.
+ This merely makes it explicit.
+
+2018-11-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ gzip: fix use of uninitialized memory
+ Problem reported by Hanno Böck (Bug#33501).
+ * NEWS: Mention this.

+ Fix by Mark Adler.
+ * tests/hufts: Add test case for the bug.
+
+2018-08-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * gzip.c (remove_output_file): Fix typo.
+
+ gzip: fix bug in signal-handling fix
+ Problem reported by Johannes Przybilla (Bug#32375#26).
+ * gzip.c (volatile_strcpy): Source is now pointer-to-volatile too.
+ (remove_output_file): Copy remove_ofname to a private nonvolatile
+ copy so that it can be passed to xunlink safely.
+
+2018-08-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix some theoretical races in signal handling
+ Problem reported by Johannes Przybilla (Bug#32375).
+ * NEWS: Mention this.
+ * bootstrap.conf (gnulib_modules): Add sigaction.
+ * gzip.c (SA_NOCLDSTOP, sigprocmask, sigset_t)
+ (siginterrupt) [!SA_NOCLDSTOP]: Remove; Gnulib not supplies these.
+ (remove_ofname): New var.
+ (volatile_strcpy): New function.
+ (create_outfile): Use it.
+ (install_signal_handlers, abort_gzip_signal): Assume sigaction.
+ (remove_output_file): New arg SIGNALS_ALREADY_BLOCKED.
+ All uses changed. Avoid unnecessary (and racy) call
+ to sigprocmask if this new arg is set.
+ (abort_gzip_signal): Assume C89 or better for signal handler type.
+ * gzip.h (RETSIGTYPE): Remove.
+ * lib/.gitignore, m4/.gitignore:
+ Add files brought in by Gnulib sigaction module. Sort.
+
+2018-08-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ gzip: port better to mingw again
+ Problem reported by Bdale Garbee (Bug#32305#8).
+ * gzip.c (do_chown): Use HAVE_FCHOWN || HAVE_CHOWN,
+ which is configured, instead of DO_CHOWN, which is not.
+
+2018-08-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ gzip: make the output more reproducible
+ Problem reported by Bernhard M. Wiedemann (Bug#32342).
+ * NEWS: Mention this.
+ * doc/gzip.texi (Overview, Invoking gzip): Document this.
+ * gzip.c (get_input_size_and_time): New function,
+ which implements the change.
+ (treat_stdin, treat_file): Use it.
+ * tests/reproducible: New test.
+ * tests/Makefile.am (TESTS): Add it.
+
+2018-07-29 Paul Eggert <eggert@cs.ucla.edu>

+
+2018-06-30 Jim Meyering <meyering@fb.com>
+
+ build: remove -Wformat-truncation=2 to avoid avoid false-positive
+ * configure.ac (GNULIB_WARN_CFLAGS): Add -Wformat-truncation=2,
+ to disable it when building gnulib with --enable-gcc-warnings.
+ This avoids what looks like a false positive from GCC 9:
+ strerror_r.c: In function 'rpl_strerror_r':
+ strerror_r.c:453:35: error: 'Unknown error ' directive output \
+ truncated writing 14 bytes into a region of size 2 \

+
+ gzexe: port to macOS mktemp
+ 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 "-").

+
+2017-11-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ maint: zforce and zmore exit status cleanup
+ Problem reported by Nelson H. F. Beebe.
+ * zforce.in, zmore.in: On failure, exit with status 1 instead of
+ with whatever failing status that printf or mv exited with.
+
+2017-11-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ gzexe: ensure file always exists
+ * gzexe.in: When in a filesystem that does not support symlinks,
+ use rm+cp rather than mv to make backups, so that the argument
+ file always exists.

+ fall back to using mv -f.
+ Reported by Bruno Haible in http://debbugs.gnu.org/29266
+
+2017-11-15 Jim Meyering <meyering@fb.com>
+
+ build: make each generated script unwritable
+ * Makefile.am (.in): Ensure that each generated script is unwritable.
+ This makes it less likely that someone (even me) will mistakenly
+ modify one of those generated files.
+
+2017-11-13 Jim Meyering <meyering@fb.com>
+
+ zless, znew: exit 1 upon --help or --version write failure
+ * zless.in: Exit 1 upon --help or --version write error.
+ * znew.in: Likewise.
+
+2017-11-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ maint: script diagnostics status cleanup
+ 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.
+
+ tests: don’t be so strict about timestamps
+ * tests/timestamp: We’ve had many false alarms about timestamps
+ that are not gzip problems, but instead are problems with ‘touch’.
+ Attempt to work around them by not trusting ‘touch’ so much.
+ Problems and parts of solutions proposed by Bruno Haible.
+
+2017-11-10 Paul Eggert <eggert@cs.ucla.edu>
+
+ build: update gnulib submodule to latest
+
+2017-11-09 Jim Meyering <meyering@fb.com>
+
+ gnulib: update to latest
+
+ maint: use noreturn, not ATTRIBUTE_NORETURN
+ Use gnulib's stdnoreturn module so we can include
+ <stdnoreturn.h> and the "noreturn" helper macro, thus
+ replacing the definition and uses of ATTRIBUTE_NORETURN.
+ * bootstrap.conf (gnulib_modules): Add stdnoreturn.
+ * gzip.h (ATTRIBUTE_NORETURN): Remove definition.
+ Include stdnoreturn.h and use "noreturn" for each
+ ATTRIBUTE_NORETURN-adorned function declaration.
+ * gzip.c (do_exit, try_help): Use "noreturn".
+
+ tests: unpack-invalid: correct and clean up a test
+ * tests/unpack-invalid: There was a logic error that would have
+ caused this test to ignore a failure if first iteration of the
+ loop set fail=1 and the second one reset it to 0. Also, use
+ "returns_ 1 ...", to require an exit status of 1.
+
+2017-11-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ gzip: diagnose out-of-range MTIME
+ This seems to be the problem reported by Bruno Haible for GNU/Hurd
+ i386 with touch 8.26 and glibc 2.24 (Bug#29033#20).
+ * NEWS: Document this.
+ * gzip.c (get_method): If MTIME is out of range for
+ this platform, warn and substitute the nearest in-range
+ value, instead of silently ignoring it.
+ (do_list): Remove no-longer-needed test for unknown time stamp.
+
+2017-11-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ misc: diagnose year-2038 configuration problems
+ * bootstrap.conf (gnulib_modules): Add year2038.
+ * m4/.gitignore: Add year2038.m4[
+
+ maint: remove IMPORT_FROM_GETTEXT
+ * bootstrap.conf (IMPORT_FROM_GETTEXT): Remove.
+ This is a relic from older Gnulib, and has no effect now.
+
+2017-10-29 Jim Meyering <meyering@fb.com>
+
+ tests/unpack-valid: port to printf that do not grok hex
+ Many versions of printf do not handle hexadecimal in a format string,
+ so this test would fail.
+ * tests/init.cfg (hex_printf_): Copied from grep's tests/init.cfg.
+ * tests/unpack-valid: Use hex_printf_.
+ Reported by Bruno Haible in https://bugs.gnu.org/29033#26
+
+ gnulib: update to latest; also update tests/init.sh from gnulib
+
+ gzip: fix bug with any upper case custom ('-S'-specified) suffix
+ Any user-specified suffix with an upper case
+ letter would fail to match desired file.
+ * gzip.c (get_suffix): First, arrange to have only one return
+ point rather than two. Put a lower-cased (just-malloc'd) copy
+ of z_suffix in the suffix vector, and free it before returning.
+ * tests/upper-suffix: New file.
+ * tests/Makefile.am (TESTS): Add it.

+ 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,

+ (stdin_was_read): New static var.
+ (main): Don't use close_stdin.

+ * NEWS: Mention this.
+ * gzip.c (main): Do not close stdout twice when given -l.

+ can synchronize it if --synchronize is also specified.
+ * tests/list: New test case.
+ * tests/Makefile.am (TESTS): Add it.

+ 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.

+ 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.

+ * 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 <= $?)) + $? %

+ 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
