2024-08-27  Colin Watson  <cjwatson@debian.org>

	Recommend nullptr for varargs termination

	This is safer than `NULL`, which some platforms define to be `0` rather
	than `(void *) 0` (see
	https://thephd.dev/c23-is-coming-here-is-what-is-on-the-menu#n3042---introduce-the-nullptr-constant).
	If it isn't available, `(void *) 0` is a better fallback than `NULL`.

	* README.md, man/libpipeline.3, web/index.html: Recommend `nullptr` or
	`(void *) 0` rather than `NULL` where used to terminate variadic
	argument lists.

2024-08-27  Colin Watson  <cjwatson@debian.org>

	Fixes Savannah bug #62355 (in man-db).

	* lib/pipeline.c (argstr_get_word): Skip whitespace at the start of

	* NEWS.md: Document this.

2022-04-23  Colin Watson  <cjwatson@debian.org>

	Simplify static analysis of fatal errors

	The usual idiom for fatal error reporting in libpipeline is `error
	(FATAL, ...)` (there are a few cases using different exit codes, but
	they're less common).  Unfortunately, there's no easy way to tell the
	compiler that this call doesn't return, because `error (0, ...)` *does*
	return.  As a result, some call sites required extra work to give the
	compiler this information, which can sometimes make a difference to
	static analysis.

	To simplify this, add a new `fatal` helper function which always exits
	`FATAL` (i.e. 2) and never returns.  This is declared with
	`PIPELINE_ATTR_NORETURN` so that the compiler can straightforwardly know
	what's going on.

	* bootstrap.conf (gnulib_modules): Add verror.
	* lib/fatal.c, lib/fatal.h: New files.
	* lib/Makefile.am (libpipeline_la_SOURCES): Add fatal.c and fatal.h.

	* lib/pipeline.c (pipecmd_new_argstr, pipecmd_exec,
	pipeline_install_sigchld, pipeline_start, pipeline_wait_all,
	pipeline_pump): Use fatal.

2022-01-02  Colin Watson  <cjwatson@debian.org>

	Trim down direct Gnulib dependencies slightly

	* bootstrap.conf (gnulib_modules): Replace signal with signal-h, since
	we use the corresponding header file directly but not the corresponding
	function.

2022-01-02  Colin Watson  <cjwatson@debian.org>

	Update to Gnulib 20211231

	(--enable-gcc-warnings): New option, based on code in coreutils.  Use
	this to enable -fanalyzer only if --enable-gcc-warnings=expensive is
	used; it's useful but slow.

2022-01-02  Colin Watson  <cjwatson@debian.org>

	Add build-distcheck CI artifact

	This should eventually allow publishing release tarballs built by a CI
	process rather than on my laptop.

	* .gitlab-ci.yml (variables): Set GIT_DEPTH to 0; we need full history
	in order to build the ChangeLog file.
	(build-distcheck:before_script): Add git, needed by gitlog-to-changelog.
	(build-distcheck:artifacts): Add bootstrapped/*.tar.gz.

2022-01-02  Colin Watson  <cjwatson@debian.org>

	(pre-commit:before_script): Explicitly install git.
	(bootstrap:before_script): Explicitly install git and pkg-config.

2022-01-01  Colin Watson  <cjwatson@debian.org>

	Use Gnulib attribute.h properly

2021-11-07  Colin Watson  <cjwatson@debian.org>

	Ignore the "clang-format" commit for "git blame"

	Developers should apply the following config setting:

	    git config blame.ignoreRevsFile .git-blame-ignore-revs

2021-11-07  Colin Watson  <cjwatson@debian.org>

	Introduce clang-format

	This relieves me of the cognitive burden of having to think about
	trivial formatting details (especially when reviewing code from others,
	but also for myself).  In most cases the reformatted code is equivalent
	or superior in terms of my preferred style to what I wrote myself; there
	was one exception (in pipeline_dump) where I disabled formatting.

	* .clang-format: New file.
	* .pre-commit-config.yaml: Add clang-format hook.
	* lib/*, tests/*: Reformat using clang-format.

2021-11-07  Colin Watson  <cjwatson@debian.org>

	Simplify conditional SIGPIPE handling

	* lib/pipeline.c (IS_SIGPIPE): New macro.
	(pipecmd_exec, pipeline_wait_all): Use IS_SIGPIPE, thereby avoiding
	needing to put parts of an if/else chain inside #ifdef.

2021-09-19  Colin Watson  <cjwatson@debian.org>

	Update some obsolete Autoconf macros

	* configure.ac: Replace AC_GNU_SOURCE and AC_ISC_POSIX with
	AC_USE_SYSTEM_EXTENSIONS.  Replace AC_CONFIG_HEADER with
	AC_CONFIG_HEADERS.

2021-09-19  Colin Watson  <cjwatson@debian.org>

	Stop using obsolete AC_TRY_RUN

	This has been obsolete since Autoconf 2.55.  Use its AC_RUN_IFELSE
	expansion instead.

	* m4/pipeline-socketpair.m4 (PIPELINE_SOCKETPAIR_PIPE): Expand
	AC_TRY_RUN calls using AC_RUN_IFELSE.

2021-06-05  Colin Watson  <cjwatson@debian.org>

	* README.md (Installation): Update URLs for pkg-config and check.
	(Note on GPL versions): Update GNU licence compatibility URL to use
	HTTPS.
	* lib/pipeline.c (clearenv): Update dovecot reference; the old URL used
	HTTP and had gone stale.

2020-11-25  Colin Watson  <cjwatson@debian.org>

	Upgrade to Gnulib 20201125

	In line with Gnulib, we now require Autoconf 2.64.

	* bootstrap.conf (GNULIB_REVISION): Set to
	f2a67f071d170920314c9a3b8de3e85259b4e010.
	(buildreq): Bump required autoconf version to 2.64.

	* configure.ac: Test for check >= 0.9.10.
	* tests/argstr.c, tests/basic.c, tests/exec.c, tests/inspect.c,
	tests/pump.c, tests/read.c, tests/redirect.c: Replace uses of
	fail_unless and fail_if with appropriate ck_assert_* calls.  In most
	cases these now use more specific equality etc. tests rather than just
	passing arbitrary predicates.
	* README: Document updated dependency.
	* NEWS: Document this.

2020-07-04  Colin Watson  <cjwatson@debian.org>

	Fix handling of read/write errors

	safe_read and safe_write return size_t and define SAFE_READ_ERROR and
	SAFE_WRITE_ERROR as error return values.  We had previously been
	assigning their result to a signed value.  As a result, whether
	passthrough, pipeline_pump, and get_block would detect read/write errors
	was implementation-defined.

	* lib/pipeline.c (passthrough, get_block): Assign safe_read return value
	to a size_t rather than a signed integer type, and check for
	SAFE_READ_ERROR rather than negative values.
	(pipeline_pump): Assign safe_write return value to a size_t rather than
	an ssize_t, and check for SAFE_WRITE_ERROR rather than negative values.
	* NEWS: Document this.

2020-01-01  Colin Watson  <cjwatson@debian.org>

	Version: 1.5.2

	* NEWS: Document pipeline_start doc change

2020-01-01  Colin Watson  <cjwatson@debian.org>

	pipecmd_exec: Flush stdio in PIPECMD_FUNCTION case

	This fixes a regression in eceb4fc9c1a800739f3876a5c9538376adc77876
	where we could lose some output from functions that write to standard
	output but don't explicitly flush.

	* lib/pipeline.c (pipecmd_exec): Flush output streams before exiting in
	the PIPECMD_FUNCTION case.

2020-01-01  Colin Watson  <cjwatson@debian.org>

	pipeline_start: Document that standard FDs must be open

	Fixes Ubuntu bug #992271.

	* lib/pipeline.h (pipeline_start): Document that FDs 0, 1, and 2 must be
	open before calling this function.
	* man/libpipeline.3 (pipeline_start): Likewise.

2019-12-27  Colin Watson  <cjwatson@debian.org>

	Use _exit rather than exit in pipecmd_exec

	This avoids bugs such as functions registered using atexit being called
	multiple times.

	* lib/pipeline.c (pipecmd_exec): Call _exit rather than exit.
	* NEWS: Document this.

2019-08-30  Colin Watson  <cjwatson@debian.org>

	Enable many more GCC warnings

	* bootstrap.conf (gnulib_modules): Add manywarnings.<Paste>
	* configure.ac: Add gl_MANYWARN_ALL_GCC, with some refinements to disable
	-Wsystem-headers, -Wmissing-field-initializers, and -Winline.

2019-08-30  Colin Watson  <cjwatson@debian.org>

	Add several function attributes suggested by GCC

	* lib/debug.c (vdebug): Mark first argument as a printf format string.
	* lib/pipeline.c (pipecmd_get_nargs, pipeline_get_ncommands,
	pipeline_get_command, pipeline_get_pid, pipeline_peek_size): Mark as
	pure.

2017-07-10  Colin Watson  <cjwatson@debian.org>

	* lib/pipeline.c (get_line): A short read isn't a reliable way to detect
