+
+2011-01-03 Jim Meyering <meyering@redhat.com>

+ * NEWS: The "gzip -f foo.gz" change occurred in 1.3.13, not 1.3.12
+
+2010-11-10 Paul Eggert <eggert@cs.ucla.edu>
+
+ zgrep: don't assume traditional behavior with signal numbers
+ * zgrep.in: Don't assume the exit status is the signal number plus
+ 128, as POSIX doesn't require this. No need to kill self; exiting
+ with large status is enough. Propagate all exit statuses greater
+ than 1, not merely those in the range 129..143, as there's no need
+ to treat that range specially (and it's not portable anyway).
+
+2010-11-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ zgrep: fix shell portability bug with -f; fix mishandling of "-e -"
+ * tests/zgrep-f: Check for "zgrep -e -" bug, too.
+ * zgrep.in: Don't assume that if the shell redirects fd 6, then
+ this redirection is visible to the subsidiary grep. POSIX doesn't
+ guarantee this visibility except for file descriptors 0, 1, and 2,
+ and ksh does not support it. Problem reported by Thomas Schulz in
+ <http://lists.gnu.org/archive/html/bug-gzip/2010-11/msg00000.html>.
+ Also, fix a related bug: "-e -" was mishandled. These two bugs
+ were introduced by commit 5b54db4546b84ec97ff57a62f8ddb98faacf77f2
+ dated 2009-10-09.
+ (escape): Change the convention: do not assume that a stray X
+ is present at the end of the last line. All uses changed.
+ There was no longer any need for this convention, and fixing this
+ made it a bit easier to use 'sed' in a later part of the fix.
+
+2010-11-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ maint: fix copyright dates that were munged by a maintenance script
+ * 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.

+ build: use gnulib's lib-ignore module
+ * bootstrap.conf (gnulib_modules): Add lib-ignore, in case it helps.
+ * Makefile.am (AM_LDFLAGS): Define it.
+
+ maint: let configure-invoked cpp emit diagnostics to config.log
+ * configure.ac: Do not discard CPP's stderr.
+
+ build: update gnulib submodule to latest, and adapt
+ * cfg.mk: Update to use new _sc_search_regexp interface. Run this:
+ perl -pi -e 's/\b_prohibit_regexp\b/_sc_search_regexp/;'
+ -e 's/\bmsg=/halt=/; s/\bre=/prohibit=/;' cfg.mk
+ and then adjust backslashes so they still line up.
+ * cfg.mk (local-checks-to-skip): Add new sc_texinfo_acronym, to skip it.
+ * msdos/tailor.c (fcalloc): Mark a diagnostic for translation, to
+ placate stricter syntax-check, even though no one uses this file.
+
+ use assembly code matcher when possible
+ * configure.ac (ASCPPPOST): Backslash-escape "#" in AC_SUBST'd
+ variable, to keep make from seeing it as a comment-introducer.
+ Based on a patch by Petr Pisar.
+ * lib/Makefile.am (match.$(OBJEXT)): Use AM_V_GEN and AM_V_at.
+ * lib/match.c: Don't include <config.h>.
+ It would impede configure-time assembler test.
+ * .x-sc_require_config_h: Exempt lib/match.c from syntax-check.
+ * .x-sc_require_config_h_first: Likewise.
+
+2010-03-20 Jim Meyering <meyering@redhat.com>
+
+ do not use stat.st_mtime of a non-regular file
+ * gzip.c: Include "timespec.h".
+ (treat_stdin): Use st_mtime only from a regular file.
+ This matters at least on Cygwin 1.7.1-1, for which a stdin-pipe has
+ the mtime of /dev/null, rather than the gzip-documented-for-pipes
+ "current time". Reported by Denis Excoffier.
+
+2010-02-22 Jim Meyering <meyering@redhat.com>
+
+ tests: exercise the fix for the decompression data-loss bug
+ * tests/null-suffix-clobber: New file.
+ * Makefile.am (TESTS): Add it.
+
+ gzip: fix a data-loss bug when decompressing with --suffix=''
+ * gzip.c (main): Disallow an empty --suffix=S also with -d.
+ Otherwise, "gzip -d -S '' F.gz" would ask if it's ok to remove the
+ existing file, "F.gz"; if you reply "yes", you'd lose all of that data.
+ Use of an empty suffix was already rejected in compression mode.
+ * gzip.1 (--suffix (-S)): Do not recommend to use "gunzip -S '' *".
+ Describe how the suffix is used when decompressing, too.
+ * NEWS (Bug fixes): mention the fix.
+ Reported by Ripduman Sohan.
+
+ tests: add ---presume-input-tty option, solely for testing
+ * gzip.c: Include <stdbool.h>.
+ (presume_input_tty): New global.
+ (main): Set it.
+ (treat_stdin, check_ofname): Use it.
+
+2010-02-07 Jim Meyering <meyering@redhat.com>
+
+ doc: minor adjustment to README-release
+ * README-release: Tweak description, to sync from coreutils.
+
+ tests: add the help-version sanity tests from coreutils
+ * tests/help-version: New file, from coreutils.
+ * Makefile.am (TESTS): Add it.
+
+ tests: make distcheck invoke "make syntax-check" and other tests
+ * dist-check.mk: New file, from coreutils.
+ * cfg.mk: Include it.
+ * Makefile.am (distcheck-hook): New rule, to make us use it.
+
+ zcmp: consistently indicate failure with exit status of 2
+ * zcmp.in: Exit with status of 2 (not 1), when writing
+ --help or --version output fails, to be more like cmp.
+
+2010-02-04 Jim Meyering <meyering@redhat.com>
+
+ tests: add more tests of gzip -cdf
+ * tests/mixed: Test "gzip -cdf" for a range of small uncompressed files.
+
+ tests: flip and adjust mixed test, now that the bug is fixed
+ * NEWS (Bug fixes): Mention the fix.
+ * Makefile.am (XFAIL_TESTS): Move tests/mixed from here...
+ (TESTS): ...to here.
+ * tests/mixed: Comment out the currently (always?) failing part.
+
+2010-02-04 Mark Adler <madler@alumni.caltech.edu>
+
+ gzip -cdf now handles concatenation of gzip'd and uncompressed data
+ * util.c (copy): Change semantics so as to honor a decremented inptr.
+ * gzip.c (get_method): When needed (-cdf), decrement inptr rather
+ than clearing it -- and output the first magic byte.
+
+2010-02-04 Dmitry V. Levin <ldv@altlinux.org>
+
+ zgrep: terminate gracefully when a pipeline is interrupted by a signal
+ zgrep is not terminated gracefully when its grep/sed pipeline
+ is terminated by a signal. For example, a command like
+ zgrep -F .TH /usr/share/man/man1/*.gz | head
+ continues working long after the "head" process completes.
+ Another example, a command like
+ zgrep unmatched-pattern /usr/share/man/man1/*.gz
+ cannot be interrupted by sending a SIGQUIT with Ctrl-\ key, it outputs
+ zgrep: line 221: test: : integer expression expected
+ and goes on.
+ * zgrep.in: Terminate gracefully when the grep/sed pipeline is
+ terminated by a signal.
+ * tests/zgrep-signal: New test.
+ * Makefile.am (TESTS): Add it.
+
+2010-02-03 Jim Meyering <meyering@redhat.com>
+
+ maint: teach "make syntax-check" the space-only indentation rule
+ * cfg.mk (sc_prohibit_tab_based_indentation): New rule, from coreutils.
+ (sc_prohibit_emacs__indent_tabs_mode__setting): Likewise.
+ * bootstrap: Remove "indent-tabs-mode: nil" directive.
+ * .x-sc_prohibit_tab_based_indentation: New file.
+
+ global: convert indentation-TABs to spaces
+ Transformed via this shell code:
+ t=$'\t'
+ git ls-files \
+ | grep -vE '(^|/)((GNU)?[Mm]akefile|ChangeLog)|\.(am|mk)$' \
+ | grep -vE 'tests/pr/|help2man' \
+ | xargs grep -lE "^ *$t" \

+
+2010-02-03 Dmitry V. Levin <ldv@altlinux.org>
+
+ wrapper scripts: write diagnostics to stderr, not to stdout
+ * zforce.in: In case of usage error, output short error diagnostics to
+ stderr instead of printing help text to stdout.
+ * zmore.in: Likewise.
+ * znew.in: Likewise.
+
+2010-02-03 Jim Meyering <meyering@redhat.com>
+
+ gzip -cdf mishandles some concatenated input streams: test it
+ * tests/mixed: Exercise "gzip -cdf" bug.
+ * Makefile.am (XFAIL_TESTS): Add it.
+ Mark Adler reported the bug.
+
+ tests: move the hufts-segv test to its own file
+ * tests/hufts: New test.
+ * Makefile.am (TESTS): Add tests/
+ (check-local): Remove the hufts-segv test from this rule.
+
+ tests: begin moving tests into their own files
+ * Makefile.am (TESTS): Add tests/stdin.
+ (check-local): Move the stdin check to its own file:
+ * tests/stdin: New script.
+
+ tests: remove unnecessary use of "path_prepend_ ."
+ It is unnecessary, since Makefile.am's TESTS_ENVIRONMENT setting
+ already adds the top build directory, and besides, is only
+ marginally useful when running stand-alone, since it presumes
+ that the script is being run from the top build directory.
+ * tests/helin-segv: Remove unnecessary use of path_prepend_.
+ * tests/memcpy-abuse: Likewise.
+ * tests/trailing-nul: Likewise.
+ * tests/zdiff: Likewise.
+ * tests/zgrep-f: Likewise.
+
+ tests: note that znew-k test depends on length of temp file name
+ * tests/znew-k: Tweak diagnostic, factor and add a surprising comment.
+
+2010-02-01 Jim Meyering <meyering@redhat.com>
+
+ build: update gnulib submodule to latest
+
+2010-02-01 Dmitry V. Levin <ldv@altlinux.org>
+
+ fix "znew -K" to work without use of compress utility
+ * znew.in: Change -K option to imply -t, do not use compress(1).
+ * znew.1: Document it.
+ * tests/znew-k: New test.
+ * Makefile.am (TESTS): Add it.
+
2010-01-20 Jim Meyering <meyering@redhat.com>
+ maint: update README-release procedure
+ * README-release: sync from coreutils.
+
+ post-release administrivia
+ * NEWS: Add header line for next release.
+ * .prev-version: Record previous version.
+ * cfg.mk (old_NEWS_hash): Auto-update.
+
version 1.4
* NEWS: Record release date.

gzip -d would fail with a CRC error...
...for some inputs, and some memcpy implementations. It is possible
that an offending input has to be compressed "from FAT filesystem

Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug. Until the bug is fixed you can use this workaround:
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

+* Noteworthy changes in release 1.5 (2012-06-17) [stable]
+
+** Bug fixes
+
+ gzip -d now decodes and checks header CRC16 checksums as specified by
+ the FHCRC section of Internet RFC 1952.
+
+ "gzip -d -S '' precious.gz" is now rejected immediately. Before,
+ that command would emulate "rm -i precious.gz", but with an easily-
+ misunderstood prompt. I.e., gzip would ask if it's ok to remove the
+ existing file, "precious.gz". If you made the mistake of saying "yes",
+ it would remove that input file before attempting to uncompress it.
+
+ gzip -cdf now properly handles input consisting of gzip'd data followed
+ by uncompressed data. Before it would output raw compressed input, too.
+ For example, now "(printf x|gzip; echo y)|gzip -dcf" prints "xy\n",
+ while before it would print "x<compressed data>y\n".
+
+ gzip -rf no longer compresses files more than once (e.g., replacing
+ FOO with FOO.gz.gz) on file systems such as ZFS where a readdir
+ loop that unlinks and creates files can revisit output files.
+
+
* Noteworthy changes in release 1.4 (2010-01-20) [stable]
** Bug fixes
* Noteworthy changes in release 1.3.13 (2009-09-30) [stable]
+** 'gzip -f foo.gz' now creates a file foo.gz.gz instead of complaining.
+
** Bug fixes
gzip -d no longer fails with "-" as 2nd or subsequent argument
* znew now uses $TMPDIR (default /tmp) instead of always using /tmp.
-* 'gzip -f foo.gz' now creates a file foo.gz.gz instead of complaining.
-
* It is now documented that gzip ignores case when examining file name
extensions; for example, 'gzip test.Gz' (without -f) fails because
the file name ends in '.Gz'.

+Here are most of the steps we (maintainers) follow when making a release.
+
+* Start from a clean, up-to-date git directory on "master":
+
+ make -k maintainer-clean || { ./configure && make maintainer-clean; }
+ git checkout master
+ git pull origin master
+
+* Ensure that the latest stable versions of autoconf, automake, etc.
+ are in your PATH. See the buildreq list in bootstrap.conf for
+ the complete list of tools.
+
+* Ensure that you have no uncommitted diffs. This should produce no
+ output:
+
+ git diff
+
+* Ensure that you've pushed all changes that belong in the release:
+
+ git push origin master
+
+* Check that the NixOS/Hydra autobuilder is reporting all is well:
+
+ http://hydra.nixos.org/jobset/gnu/gzip-master
+
+* Run the following command to download any new translations:
+
+ ./bootstrap && ./configure
+
+* Pre-release testing: ensure that the following command succeeds:
+
+ make check syntax-check distcheck
+
+* From top_srcdir, run:
+
+ build-aux/do-release-commit-and-tag X.Y stable
+
+ in order to (i) set the date, version number, and release type
+ [stable/alpha/beta] on line 3 of NEWS, (ii) commit that, and (iii) tag the
+ release. See --help if you need options such as:
+
+ build-aux/do-release-commit-and-tag --branch=maint -C _build X.Y.Z stable
+
+* Run the following to create release tarballs. Your choice selects the
+ corresponding upload-to destination in the emitted gnupload command.
+ The different destinations are specified in cfg.mk. See the definitions
+ of gnu_ftp_host-{alpha,beta,stable}.
+
+ # "TYPE" must be stable, beta or alpha
+ make TYPE
+
+* Test the tarball. Copy it to a few odd-ball systems and ensure that
+ it builds and passes all tests.
+
+* While that's happening, write the release announcement that you will
+ soon post. Start with the template, $HOME/announce-gzip-X.Y
+ that was just created by that "make" command.
+
+Once all the builds and tests have passed,
+
+* Run the gnupload command that was suggested by your "make TYPE" run above.
+
+* Wait a few minutes (maybe up to 30?) and then use the release URLs to
+ download all tarball/signature pairs and use gpg --verify to ensure
+ that they're all valid.
+
+* Push the NEWS-updating changes and the new tag:
+
+ v=$(cat .prev-version)
+ git push origin master tag v$v
+
+* Announce it on Savannah first, so you can include the savannah.org
+ announcement link in the email message.
+
+ From here:
+ https://savannah.gnu.org/projects/gzip/
+ click on "submit news", then write something like the following:
+ (If there is no such button, then enable "News" for the project via
+ the Main -> "Select Features" menu item, or via this link:
+ https://savannah.gnu.org/project/admin/editgroupfeatures.php?group=gzip)
+
+ Subject: gzip-X.Y released [stable]
+ +verbatim+
+ ...paste the announcement here...
+ -verbatim-
+
+ Then go here to approve it:
+ https://savannah.gnu.org/news/approve.php?group=gzip
+
+* Send the announcement email message.
+
+* After each non-alpha release, update the on-line manual accessible via
+
+ http://www.gnu.org/software/gzip/manual/
+
+ by running this from top_srcdir:
+
+ build-aux/gnu-web-doc-update
+
+ possibly with "-C <BUILDDIR>"

+The deflation algorithm used by zip and gzip is a variation of
+Lempel-Ziv 1977 [LZ77]. It finds duplicated strings in
the input data. The second occurrence of a string is replaced by a
pointer to the previous string, in the form of a pair (distance,
length). Distances are limited to 32K bytes, and lengths are limited
2. gzip file format
+The gzip file format was standardized in Internet RFC 1952 [RFC1952].
+This section briefly describes the format and comments on some
+implementation details.
+
The pkzip format imposes a lot of overhead in various headers, which
are useful for an archiver but not necessary when only one file is
compressed. gzip uses a much simpler structure. Numbers are in little
1 byte compression method (0..7 reserved, 8 = deflate)
1 byte flags
bit 0 set: file probably ascii text
- bit 1 set: continuation of multi-part gzip file
+ bit 1 set: header CRC-16 present
bit 2 set: extra field present
bit 3 set: original file name present
bit 4 set: file comment present
- bit 5 set: file is encrypted
- bit 6,7: reserved
+ bit 5,6,7: reserved
4 bytes file modification time in Unix format
1 byte extra flags (depend on compression method)
1 byte operating system on which compression took place
? bytes optional extra field
? bytes optional original file name, zero terminated
? bytes optional file comment, zero terminated
-12 bytes optional encryption header
+2 bytes optional 16-bit header CRC
? bytes compressed data
4 bytes crc32
4 bytes uncompressed input size modulo 2^32
data. If the compressed data cannot fit in one file (in particular for
diskettes), each part starts with a header as described above, but
only the last part has the crc32 and uncompressed size. A decompressor

+may prompt for additional data for multi-part compressed files. It is
desirable but not mandatory that multiple parts be extractable
independently so that partial data can be recovered if one of the
parts is damaged. This is possible only if no compression state is
or an expansion ratio of 0.015% for large files. Note that the actual
number of used disk blocks almost never increases.
-The encryption is that of zip 1.9. For the encryption check, the
-last byte of the decoded encryption header must be zero. The time
-stamp of an encrypted file might be set to zero to avoid giving a clue

-# Some notes on gzip for the Amiga:
-# Due to a strange implementation of the RAM-Disk on Commodore's part

-# gzip ram:dir/#? ram:dir/#?/#? ...

-# Alas, the program has it's full functionality only if you have
-# Kickstart 2.0 or higher installed. This affects the expansion of
-# wildcards and the preservation of file access times. You should use
-# a shell that does wildcard expansion under Kickstart 1.3.

OPTIONS:
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
--since=DATE convert only the logs since DATE;
the default is to convert all log entries.
--format=FMT set format string for commit subject and body;
see 'man git-log' for the list of format metacharacters;
the default is '%s%n%b%n'
-
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
--help display this help and exit

+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:
+

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+ for FUNCTION which will then trigger a compiler warning containing
+ the text of "literal string" anywhere that function is called, if
+ supported by the compiler. If the compiler does not support this
+ feature, the macro expands to an unused extern declaration.
+
+ This macro is useful for marking a function as a potential
+ portability trap, with the intent that "literal string" include
+ instructions on the replacement function that should be used
+ instead. However, one of the reasons that a function is a
+ portability trap is if it has the wrong signature. Declaring
+ FUNCTION with a different signature in C is a compilation error, so
+ this macro must use the same type as any existing declaration so
+ that programs that avoid the problematic FUNCTION do not fail to
+ compile merely because they included a header that poisoned the
+ function. But this implies that _GL_WARN_ON_USE is only safe to
+ use if FUNCTION is known to already have a declaration. Use of
+ this macro implies that there must not be any other macro hiding
+ the declaration of FUNCTION; but undefining FUNCTION first is part
+ of the poisoning process anyway (although for symbols that are
+ provided only via a macro, the result is a compilation error rather
+ than a warning containing "literal string"). Also note that in
+ C++, it is only safe to use if FUNCTION has no overloads.
+
+ For an example, it is possible to poison 'getline' by:
+ - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+ [getline]) in configure.ac, which potentially defines
+ HAVE_RAW_DECL_GETLINE
+ - adding this code to a header that wraps the system <stdio.h>:
+ #undef getline
+ #if HAVE_RAW_DECL_GETLINE
+ _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+ "not universally present; use the gnulib module getline");
+ #endif
+
+ It is not possible to directly poison global variables. But it is
+ possible to write a wrapper accessor function, and poison that
+ (less common usage, like &environ, will cause a compilation error
+ rather than issue the nice warning, but the end result of informing
+ the developer about their portability problem is still achieved):
+ #if HAVE_RAW_DECL_ENVIRON
+ static inline char ***rpl_environ (void) { return &environ; }
+ _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");

-/* _GL_WARN_ON_USE(function, "literal string") issues a declaration
- for FUNCTION which will then trigger a compiler warning containing
- the text of "literal string" anywhere that function is called, if
- supported by the compiler. If the compiler does not support this
- feature, the macro expands to an unused extern declaration.
-
- This macro is useful for marking a function as a potential
- portability trap, with the intent that "literal string" include
- instructions on the replacement function that should be used
- instead. However, one of the reasons that a function is a
- portability trap is if it has the wrong signature. Declaring
- FUNCTION with a different signature in C is a compilation error, so
- this macro must use the same type as any existing declaration so
- that programs that avoid the problematic FUNCTION do not fail to
- compile merely because they included a header that poisoned the
- function. But this implies that _GL_WARN_ON_USE is only safe to
- use if FUNCTION is known to already have a declaration. Use of
- this macro implies that there must not be any other macro hiding
- the declaration of FUNCTION; but undefining FUNCTION first is part
- of the poisoning process anyway (although for symbols that are
- provided only via a macro, the result is a compilation error rather
- than a warning containing "literal string"). Also note that in
- C++, it is only safe to use if FUNCTION has no overloads.
-
- For an example, it is possible to poison 'getline' by:
- - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
- [getline]) in configure.ac, which potentially defines
- HAVE_RAW_DECL_GETLINE
- - adding this code to a header that wraps the system <stdio.h>:
- #undef getline
- #if HAVE_RAW_DECL_GETLINE
- _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
- "not universally present; use the gnulib module getline");
- #endif
-
- It is not possible to directly poison global variables. But it is
- possible to write a wrapper accessor function, and poison that
- (less common usage, like &environ, will cause a compilation error
- rather than issue the nice warning, but the end result of informing
- the developer about their portability problem is still achieved):
- #if HAVE_RAW_DECL_ENVIRON
- static inline char ***rpl_environ (void) { return &environ; }
- _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
- # undef environ
- # define environ (*rpl_environ ())
- #endif

+ 4mGzip24m reduces the size of the named files using Lempel-Ziv coding

consists of small parts only, the longest parts are truncated. For
example, if file names are limited to 14 characters, gzip.msdos.exe is
compressed to gzi.msd.exe.gz. Names are not truncated on systems which
do not have a limit on file name length.

Compression is always performed, even if the compressed file is
slightly larger than the original. The worst case expansion is a few

- When writing compressed data to a tape, it is generally necessary to
- pad the output with zeroes up to a block boundary. When the data is
- read and the whole block is passed to gunzip for decompression, gunzip
- detects that there is extra trailing garbage after the compressed data
- and emits a warning by default. You have to use the --quiet option to
- suppress the warning. This option can be set in the GZIP environment

+ For each time stamp T, this code assumes that either:
+
+ * T.tv_nsec is in the range 0..999999999; or
+ * T.tv_sec corresponds to a valid leap second on a host that supports
+ leap seconds, and T.tv_nsec is in the range 1000000000..1999999999; or
+ * T.tv_sec is the minimum time_t value and T.tv_nsec is -1; or
+ T.tv_sec is the maximum time_t value and T.tv_nsec is 2000000000.
+ This allows for special struct timespec values that are less or
+ greater than all possible valid time stamps.
+
+ In all these cases, it is safe to subtract two tv_nsec values and
+ convert the result to integer without worrying about overflow on
+ any platform of interest to the GNU project, since all such
+ platforms have 32-bit int or wider.
+
+ Replacing "(int) (a.tv_nsec - b.tv_nsec)" with something like
+ "a.tv_nsec < b.tv_nsec ? -1 : a.tv_nsec > b.tv_nsec" would cause
+ this function to work in some cases where the above assumption is
+ violated, but not in all cases (e.g., a.tv_sec==1, a.tv_nsec==-2,
+ b.tv_sec==0, b.tv_nsec==999999999) and is arguably not worth the

+ detecting some invalid cases on platforms that detect integer

But this has the problem that two invocations of verify from
within the same macro would collide, since the __LINE__ value
- would be the same for both invocations.

+ macro solves this problem, but is not portable.)
A solution is to use the sizeof operator. It yields a number,
getting rid of the identity of the type. Declarations like
Which of the following alternatives can be used?
extern int dummy [sizeof (struct {...})];
- extern int dummy [sizeof (struct verify_type__ {...})];
+ extern int dummy [sizeof (struct _gl_verify_type {...})];
extern void dummy (int [sizeof (struct {...})]);
- extern void dummy (int [sizeof (struct verify_type__ {...})]);
+ extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
extern int (*dummy (void)) [sizeof (struct {...})];
- extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
+ extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
In the second and sixth case, the struct type is exported to the
outer scope; two such declarations therefore collide. GCC warns
extern int (*dummy (void)) [sizeof (struct {...})];
- * This implementation exploits the fact that GCC does not warn about
- the last declaration mentioned above. If a future version of GCC
- introduces a warning for this, the problem could be worked around
- by using code specialized to GCC, e.g.,:
+ * GCC warns about duplicate declarations of the dummy function if
+ -Wredundant_decls is used. GCC 4.3 and later have a builtin
+ __COUNTER__ macro that can let us generate unique identifiers for
+ each dummy function, to suppress this warning.
- #if 4 <= __GNUC__
- # define verify(R) \
- extern int (* verify_function__ (void)) \
- [__builtin_constant_p (R) && (R) ? 1 : -1]
- #endif
+ * This implementation exploits the fact that older versions of GCC,
+ which do not support _Static_assert, also do not warn about the
+ last declaration mentioned above.
* In C++, any struct definition inside sizeof is invalid.
Use a template type to work around the problem. */

+# libc.so.1 => /lib/libc.so.1

+# libm.so.2 => /lib/libm.so.2

+# Note that the option works only for the C compiler, not for the C++

+# - Sun C likes '-Wl,-z,ignore'.

+# - IGNORE_UNUSED_LIBRARIES_CFLAGS for C
+# - IGNORE_UNUSED_LIBRARIES_CXXFLAGS for C++
+# - IGNORE_UNUSED_LIBRARIES_FFLAGS for Fortran

+# Note that the option works only for direct invocation of the compiler, not
+# through libtool: When libtool is used to create a shared library, it will

+dnl gl_THREADLIB
+dnl ------------
+dnl Tests for a multithreading library to be used.
+dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
+dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
+dnl default is 'no', otherwise it is system dependent. In both cases, the user
+dnl can change the choice through the options --enable-threads=choice or
+dnl --disable-threads.
+dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
+dnl USE_PTH_THREADS, USE_WINDOWS_THREADS
+dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
+dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
+dnl libtool).
+dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
+dnl programs that really need multithread functionality. The difference
+dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
+dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
+dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
+dnl multithread-safe programs.

-To build GZIP for PRIMOS you should just have to type:
-
- r *>primos>build
-
-while standing in the directory above this PRIMOS subdirectory.
-
-If the files in these directories looks strange, then it might be
-because they are in normal ASCII. You'll need to convert them into
-PASCII before you will be able to build the GZIP executable.
-
-You can find a simple ASCII to PASCII converter via anonymous FTP
-from "ftp.lysator.liu.se" in the directory "pub/primos/run" as
-the file "topascii.run".
-
-You can reach me at a number of places in case there are any bugs
-in this port to report...

-README file for gzip on VMS
-written by Klaus Reimann <kr@cip.physik.uni-stuttgart.de>
-
-Here is a list of the files in [.vms]:
-
-GZIP.HLP ! Help-file, how to use gzip
-MAKEFILE.GCC ! Description for (vms-)make, using gcc
-MAKEFILE.MMS ! Description for MMS-utility, using vaxc
-MAKEFILE.VMS ! Description for (vms-)make, using vaxc
-MAKEGZIP.COM ! simple and robust DCL-Script, using vaxc
-README.VMS ! this file, how to install gzip
-VMS.C ! VMS-specific functions in gzip
-
-This file describe, how to compile and install the VMS-Port of gzip.
->>For restrictions or bugs due to the structure of the vms-file system
-refer to gzip.hlp.<<
-
-Installing gzip
-
-Since there are many makefiles there are many possibilities
-compiling and installing gzip. For most of them, it is important,
-that you start them from the SOURCE-Directory (that is where
-gzip.c is), not from the [.vms]-directory. Otherwise the compiler
-won't find the source-files.
-
-Using gcc saves disk-space, but needs longer to compile
- VAXC gzip.exe 95/96 Blocks
- gcc2.3.3 gzip.exe 86/87 Blocks
-
-To install gzip one has to perform the following steps:
- 1. compile sources (*.c, [.vms]*.c)
- 2. link executable gzip.exe
- 3. Make entries gunzip.exe and zcat.exe to gzip.exe.
- These are similar to hardlinks in UNIX
- >>If You wish to do this by hand, see for example makegzip.com.<<
- The Entries can't be simply deleted, use 'set file /remove' .
-
- 4. Rename executables (*.exe) to Your prefered exe-directory. If it is on
- another Device, then you should only copy gzip.exe and do the
- entries gunzip.exe and zcat.exe by hand (3.).
-
- 5. Setting up Symbols for the executables:
- Place the following lines in Your login.com
- Change "disk:[directory]" as appropriate.
- $ gzip == "$disk:[directory]gzip.exe"
- $ gunzip == "$disk:[directory]gunzip.exe"
- $ zcat == "$disk:[directory]zcat.exe"
- 6. insert help-file gzip.hlp in any Help-library,
- for example in sys$help:helplib.
- this can be done by $lib sys$help:helplib/help gzip
- (I did not try this command)
-
-Steps (4.)5. through 6 must be done by hand.
-Steps 1 through 3(4.) may be done by one of the makefiles:
-
-a) MAKEGZIP.COM
-This was crated from MAKEFILE.VMS and later on edited. It uses the
-VAXC-Compiler and does compiling, linking and making the entries.
-Usage:
-- change to the Source-Directory
-- copy vms.c
- $copy [.vms]vms.c []
-- start compiling, linking, entries
- $@[.vms]makegzip
-if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
-continue at Step 4.
-
-b) MAKEFILE.VMS
-Makefile for a vms-make utility (NOT gnu-make).
-Is uses the VAXC-Compiler and has the Advantage over MAKEGZIP.COM
-that make checks dependencies. This is helpfull if You have to
-recompile several times, for example after editing the sources.
-- change to the Source-Directory
-- copy vms.c
- $copy [.vms]vms.c []
-- start compiling, linking, entries
- $make /input=[.vms]makefile.vms
-if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
-Continue at Step 4.
-
-c) MAKEFILE.GCC
-Same as MAKEFILE.VMS, but uses gcc
-- Use $make /input=[.vms]makefile.gcc instead of make ....
-
-d) MAKEFILE.MMS
-Makefile for the MMS-utility. Similar to MAKEFILE.VMS
-- Use $mms /description=[.vms]makefile.mms instead of make ....

-1 GZIP
-NAME
- gzip, gunzip, zcat - compress or expand files
-
-SYNOPSIS
- gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]
- gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]
- zcat [ -fhLV ] [ name ... ]
-
-2 DESCRIPTION
- Gzip reduces the size of the named files using Lempel-Ziv
- coding (LZ77). Whenever possible, each file is replaced by
- one with the extension .gz, while keeping the same ownership
- modes, access and modification times. (The default exten-
- sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT
- and Atari.) If no files are specified, or if a file name is
- "-", the standard input is compressed to the standard out-
- put. Gzip will only attempt to compress regular files.
-
- If the compressed file name is too long for its file system,
- gzip truncates it. Gzip attempts to truncate only the parts
- of the file name longer than 3 characters. (A part is del-
- imited by dots.) If the name consists of small parts only,
- the longest parts are truncated. For example, if file names
- are limited to 14 characters, gzip.msdos.exe is compressed
- to gzi.msd.exe.gz. Names are not truncated on systems which
- do not have a limit on file name length.
-
- By default, gzip keeps the original file name and timestamp
- in the compressed file. These are used when decompressing
- the file with the -N option. This is useful when the
- compressed file name was truncated or when the time stamp
- was not preserved after a file transfer.
-
- Compressed files can be restored to their original form
- using gzip -d or gunzip or zcat. If the original name saved
- in the compressed file is not suitable for its file system,
- a new name is constructed from the original one to make it
- legal.
-
- gunzip takes a list of files on its command line and
- replaces each file whose name ends with .gz, -gz, .z, -z, _z
- or .Z and which begins with the correct magic number with an
- uncompressed file without the original extension. gunzip
- also recognizes the special extensions .tgz and .taz as
- shorthands for .tar.gz and .tar.Z respectively. When
- compressing, gzip uses the .tgz extension if necessary
- instead of truncating a file with a .tar extension.
-
- gunzip can currently decompress files created by gzip, zip,
- compress, compress -H or pack. The detection of the input
- format is automatic. When using the first two formats,
- gunzip checks a 32 bit CRC. For pack, gunzip checks the
- uncompressed length. The standard compress format was not
- designed to allow consistency checks. However gunzip is
- sometimes able to detect a bad .Z file. If you get an error
- when uncompressing a .Z file, do not assume that the .Z file
- is correct simply because the standard uncompress does not
- complain. This generally means that the standard uncompress
- does not check its input, and happily generates garbage out-
- put. The SCO compress -H format (lzh compression method)
- does not include a CRC but also allows some consistency
- checks.
-
- Files created by zip can be uncompressed by gzip only if
- they have a single member compressed with the 'deflation'
- method. This feature is only intended to help conversion of
- tar.zip files to the tar.gz format. To extract zip files
- with several members, use unzip instead of gunzip.
-
- zcat is identical to gunzip -c. (On some systems, zcat may
- be installed as gzcat to preserve the original link to
- compress.) zcat uncompresses either a list of files on the
- command line or its standard input and writes the
- uncompressed data on standard output. zcat will uncompress
- files that have the correct magic number whether they have a
- .gz suffix or not.
-
- Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP.
- The amount of compression obtained depends on the size of
- the input and the distribution of common substrings. Typi-
- cally, text such as source code or English is reduced by
- 60-70%. Compression is generally much better than that
- achieved by LZW (as used in compress), Huffman coding (as
- used in pack), or adaptive Huffman coding (compact).
-
- Compression is always performed, even if the compressed file
- is slightly larger than the original. The worst case expan-
- sion is a few bytes for the gzip file header, plus 5 bytes
- every 32K block, or an expansion ratio of 0.015% for large
- files. Note that the actual number of used disk blocks
- almost never increases. gzip preserves the mode, ownership
- and timestamps of files when compressing or decompressing.
-
-2 OPTIONS
- -a --ascii
- Ascii text mode: convert end-of-lines using local con-
- ventions. This option is supported only on some non-
- Unix systems. For MSDOS, CR LF is converted to LF when
- compressing, and LF is converted to CR LF when
- decompressing.
-
- -c --stdout --to-stdout
- Write output on standard output; keep original files
- unchanged. If there are several input files, the out-
- put consists of a sequence of independently compressed
- members. To obtain better compression, concatenate all
- input files before compressing them.
-
- -d --decompress --uncompress
- Decompress.
-
- -f --force
- Force compression or decompression even if the file has
- multiple links or the corresponding file already
- exists, or if the compressed data is read from or writ-
- ten to a terminal. If the input data is not in a format
- recognized by gzip, and if the option --stdout is also
- given, copy the input data without change to the stan-
- dard output: let zcat behave as cat. If -f is not given,
- and when not running in the background, gzip prompts to
- verify whether an existing file should be overwritten.
-
- -h --help
- Display a help screen and quit.
-
- -l --list
- For each compressed file, list the following fields:
-
- compressed size: size of the compressed file
- uncompressed size: size of the uncompressed file
- ratio: compression ratio (0.0% if unknown)
- uncompressed_name: name of the uncompressed file
-
- The uncompressed size is given as -1 on VMS because it
- it is not possible to seek reliably to the end of the
- compressed file, where this size is stored.
-
- In combination with the --verbose option, the following
- fields are also displayed:
-
- method: compression method
- crc: the 32-bit CRC of the uncompressed data
- date & time: time stamp for the uncompressed file
-
- The compression methods currently supported are
- deflate, compress, lzh (SCO compress -H) and pack. The
- crc is given as ffffffff on VMS for the reason given
- above about the uncompressed size.
-
- With --name, the uncompressed name, date and time are
- those stored within the compress file if present.
-
- With --verbose, the size totals and compression ratio
- for all files is also displayed, unless some sizes are
- unknown. With --quiet, the title and totals lines are
- not displayed.
-
- -L --license
- Display the gzip license and quit.
-
- -n --no-name
- When compressing, do not save the original file name
- and time stamp by default. (The original name is always
- saved if the name had to be truncated.) When
- decompressing, do not restore the original file name if
- present (remove only the gzip suffix from the
- compressed file name) and do not restore the original
- time stamp if present (copy it from the compressed
- file). This option is the default when decompressing.
-
- -N --name
- When compressing, always save the original file name
- and time stamp; this is the default. When decompress-
- ing, restore the original file name and time stamp if
- present. This option is useful on systems which have a
- limit on file name length or when the time stamp has
- been lost after a file transfer.
-
- -q --quiet
- Suppress all warnings.
-
- -r --recursive
- Travel the directory structure recursively. If any of
- the file names specified on the command line are direc-
- tories, gzip will descend into the directory and
- compress all the files it finds there (or decompress
- them in the case of gunzip ).
-
- -S suf --suffix suf
- Use suffix suf instead of -gz. Any suffix can be
- given, but suffixes other than -z and -gz should be
- avoided to avoid confusion when files are transferred
- to other. A null suffix forces gunzip to try
- decompression on all given files regardless of suffix,
- as in:
-
- gunzip --suffix "" *.*
-
- Previous versions of gzip used the -z suffix. This was
- changed to avoid a conflict with pack on Unix.
-
- -t --test
- Test. Check the compressed file integrity.
-
- -v --verbose
- Verbose. Display the name and percentage reduction for
- each file compressed or decompressed.
-
- -V --version
- Version. Display the version number and compilation
- options then quit.
-
- -# --fast --best
- Regulate the speed of compression using the specified
- digit #, where -1 or --fast indicates the fastest
- compression method (less compression) and -9 or --best
- indicates the slowest compression method (best compres-
- sion). The default compression level is -6 (that is,
- biased towards high compression at expense of speed).
-
-2 ENVIRONMENT
- The environment variable GZIP_OPT can hold a set of default
- options for gzip. These options are interpreted first and
- can be overwritten by explicit command line parameters. For
- example:
- define GZIP_OPT "-8 -v"
-
-2 SEE ALSO
- compress, zip, unzip
-
-2 DIAGNOSTICS
- Exit status is normally 0; if an error occurs, exit status
- is 1. If a warning occurs, exit status is 2.
-
- Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
- Invalid options were specified on the command line.
- file: not in gzip format
- The file specified to gunzip has not been
- compressed.
- file: Corrupt input. Use zcat to recover some data.
- The compressed file has been damaged. The data up to
- the point of failure can be recovered using
- define /user sys$output file.recover
- zcat file
- file: compressed with xx bits, can only handle yy bits
- File was compressed (using LZW) by a program that
- could deal with more bits than the decompress code
- on this machine. Recompress the file with gzip,
- which compresses better and uses less memory.
- file: already has -gz suffix -- no change
- The file is assumed to be already compressed.
- Rename the file and try again.
- file already exists; do you wish to overwrite (y or n)?
- Respond "y" if you want the output file to be
- replaced; "n" if not.
- gunzip: corrupt input
- A SIGSEGV violation was detected which usually means
- that the input file has been corrupted.
- xx.x%
- Percentage of the input saved by compression.
- (Relevant only for -v and -l.)
- -- not a regular file or directory: ignored
- When the input file is not a regular file or direc-
- tory, it is left unaltered.
-
-2 CAVEATS
- On VMS:
- - upper case options need quotes: gzip "-V".
- - restoration of timestamps and version numbers is not supported
- - If a compressed file already exists, gzip -f overwrites it, it
- does not create a new version.
- - multi-part gzip files are not supported.
- - gunzip does not preserve the input file format. You can use a
- separate utility to restore the original format.
- - gunzip and zcat can be used only if you have created the
- links to gzip as documented in makegzip.com. Otherwise
- you must use explicit parameters ("gzip -c" or "gzip -dc").
- - gzip --list cannot give the uncompressed size and crc.
-
- When writing compressed data to a tape, it is generally
- necessary to pad the output with zeroes up to a block boun-
- dary. When the data is read and the whole block is passed to
- gunzip for decompression, gunzip detects that there is extra
- trailing garbage after the compressed data and emits a warn-
- ing by default. You have to use the --quiet option to
- suppress the warning. This option can be set in the GZIP_OPT
- environment variable as in:
- define GZIP_OPT "-q"
-
-2 BUGS
- On VMS, files in VFC record format are not correctly handled by
- the C runtime library (the linefeed character is suppressed).
-
- In some rare cases, the --best option gives worse compres-
- sion than the default compression level (-6). On some highly
- redundant files, compress compresses better than gzip.
