	Upstream-Status: Submitted [https://gitlab.com/man-db/man-db/-/merge_requests/13]

2025-02-13  Colin Watson  <cjwatson@debian.org>

	manpath(5): Fix minor formatting issues

	Reported by Bjarni Ingi Gislason.  Fixes Debian bug #1095890.

	* man/man5/manpath.man5 (DESCRIPTION): Use `.I` rather than `.IR` where
	there is only one argument.  Use `\:` to indicate where a long search
	path string may be broken across lines.

2025-01-23  Colin Watson  <cjwatson@chiark.greenend.org.uk>

	Merge branch 'flex' into 'main'

	configure: check for shipped generated sources in source directory

	See merge request man-db/man-db!12

2025-01-22  Ross Burton  <ross.burton@arm.com>

	configure: check for shipped generated sources in source directory

	The configure script fails if it can't find flex and the pregenerated
	source code isn't available, as is the case in builds from git whereas
	tarballs include the code.

	However this breaks with out-of-tree builds, where cwd during configure
	is the build directory not the source directory, and the pregenerated
	sources will always be inside the source directory.

2025-01-19  Colin Watson  <cjwatson@debian.org>

	Tolerate additional spaces in preprocessor strings

	Fixes https://bugs.debian.org/1093431.

	* src/man.c (get_preprocessors_from_file): Skip over extra spaces after
	`PP_COOKIE`.

	man/man1/manpath.man1 (BUGS), man/man1/whatis.man1 (BUGS),
	man/man1/zsoelim.man1 (BUGS), man/man5/manpath.man5 (BUGS),
	man/man8/accessdb.man8 (BUGS), man/man8/catman.man8 (BUGS),
	man/man8/mandb.man8 (BUGS): Use `\-` instead of `-` when a literal
	U+002D HYPHEN-MINUS is required.

2024-10-27  Bjarni Ingi Gislason  <bjarniig@simnet.is>

	man(1): Fix minor formatting issues

	Fixes https://bugs.debian.org/1085485.

	* man/man1/man.man1 (EXAMPLES): Use matching font for both quote
	characters in `man 'man(7)'`.
	(Controlling formatted output): Avoid unnecessary centring of table
	headers.  Use `.B` instead of `.BR` when there is only a single
	argument.
	(ENVIRONMENT, BUGS): Use `\-` instead of `-` when a literal U+002D
	HYPHEN-MINUS is required.

2024-09-24  Rafael Fontenelle  <rafaelff@gnome.org>

	Update Brazilian Portuguese translation

2024-08-29  Colin Watson  <cjwatson@debian.org>

	Add sbindir to PATH when testing an installed package

	* src/tests/Makefile.am (TESTS_ENVIRONMENT): Add `sbindir`.
	* src/tests/testlib.sh: If `MAN_TEST_INSTALLED` is non-empty, also
	prepend `$sbindir` to `PATH`.

2024-08-29  Colin Watson  <cjwatson@debian.org>

	Release man-db 2.13.0

2024-08-28  Colin Watson  <cjwatson@debian.org>

	README.md: Update my copyright notice

2024-08-28  Colin Watson  <cjwatson@debian.org>

	Further improve table formatting in description of --ascii

	Fixes https://bugs.debian.org/1073530, again.

	The use of text blocks here was an attempt (in
	6000c56fb621b454185b04d0d718ede9a87eadf4) to make this page more robust
	against the possibility of translations that were long enough to cause
	the table to be overly wide otherwise.  However, in the 13 years since I
	added them, no language has produced long enough translations for this
	to be a problem, and this defence against a hypothetical problem causes
	real formatting issues because `tbl` formats text blocks in a diversion
	whose width is calculated in advance and is difficult to set
	appropriately.

	If a translation comes along in future that pushes the column limits
	harder, then one option would be to drop the "Octal" column, which
	arguably provides an excessive level of detail.

	* man/man1/man.man1 (Controlling formatted output): In the description
	of `--ascii`, abandon text blocks and drop workarounds that attempted to
	improve their formatting.

2024-08-28  Colin Watson  <cjwatson@debian.org>

	Document clang-format and pre-commit

	* docs/HACKING.md (Coding style): Replace description of manual code
	formatting with mentions of `clang-format` and `pre-commit`.

2024-08-28  Colin Watson  <cjwatson@debian.org>

	Use nullptr in a couple more places

	* docs/HACKING.md (Facilities and portability): Advise terminating
	variadic argument lists with `nullptr` rather than `NULL`.
	* src/zsoelim.l (try_compressed): Terminate `appendstr` argument list
	with `nullptr` rather than `NULL`.

2024-08-28  Colin Watson  <cjwatson@debian.org>

	Support running the test suite against an installed package

	To do this, run `make check MAN_TEST_INSTALLED=1` from a built tree.
	This is useful for systems such as Debian's autopkgtest framework, which
	run packages' tests when their dependencies change.

	* man/check-man: If `MAN_TEST_INSTALLED` is non-empty, run `man` from
	the installed system rather than from the build tree.
	* src/tests/Makefile.am (TESTS_ENVIRONMENT): Sort lexicographically.
	Remove `PATH`.  Add `pkglibexecdir`.
	* src/tests/testlib.sh: If `MAN_TEST_INSTALLED` is non-empty, prepend
	`$pkglibexecdir` to `PATH` and run programs from the installed system
	rather than from the build tree.
	* NEWS.md: Document this.

2024-08-28  Colin Watson  <cjwatson@debian.org>

	Fix -Wflex-array-member-not-at-end warning with GCC 14

	* lib/orderfiles.c (order_files) [HAVE_LINUX_FIEMAP_H]: Avoid relying on

	member to be a member of another structure but not the last field.
	* NEWS.md: Document this.

2024-08-28  Colin Watson  <cjwatson@debian.org>

2024-08-05  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

2024-08-05  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.

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

2024-05-23  Colin Watson  <cjwatson@debian.org>

	Drop support for groff < 1.21

	groff 1.21 was released at the end of 2010, and to support older
	versions we were carrying some awkward code which is probably no longer
	relevant on any system where people install current versions of man-db.

	default behaviour on systems using groff.
	* docs/INSTALL.quick: Document nroff/troff requirement.
	* lib/encodings.c (directory_table, charset_table,
	fallback_default_device, device_table, less_charset_table): Remove
	`MULTIBYTE_GROFF` conditionals and consolidate entries into main tables
	where relevant.
	(compatible_encodings): Remove `MULTIBYTE_GROFF` case, which was only
	relevant to the old Debian multibyte patch.
	(get_roff_encoding): Likewise.  Add `ATTRIBUTE_PURE`.
	* m4/man-gnu-nroff.m4: Check for `preconv` (previously checked in
	configure.ac).
	* src/man.c (locale_macros): Remove groff version check.
	* src/tests/man-language-specific-request: Adjust expected spacing.
	* NEWS.md: Document this.

	* .pre-commit-config.yaml (shellcheck-py): Update to v0.10.0.1.
	* src/tests/mandb-purge-updates-timestamp: Disable shellcheck SC2319;
	the use of `$?` here is not problematic.
	* tools/checkman: Use `find -newer` rather than non-POSIX `test -nt`.

2024-03-28  Colin Watson  <cjwatson@debian.org>

	* NEWS.md: Document this.

2024-03-19  Colin Watson  <cjwatson@debian.org>

	Move setting of seccomp attributes earlier

	This doesn't need to be done every time we load the filter; it can be
	done when constructing the filter instead.

	* lib/sandbox.c (_sandbox_load): Move `seccomp_attr_set` call to ...
	(make_seccomp_filter): ... here.

2024-03-18  Colin Watson  <cjwatson@debian.org>

	web: Update bootstrapping instructions

	* web/development.html: Bootstrapping from git now requires
	`./bootstrap` rather than `./autogen.sh`.

2024-03-18  Colin Watson  <cjwatson@debian.org>

	Tighten up several declarations

2024-03-03  Colin Watson  <cjwatson@debian.org>

	Speed up seccomp filter slightly

	Thanks to systemd for the idea.  With a couple of hundred entries in the
	filter (depending on architecture and permissiveness), using a binary-tree
	search should be worth it.

	* lib/sandbox.c (_sandbox_load): Set `SCMP_FLTATR_CTL_OPTIMIZE` to 2 if
	available.
	* NEWS.md: Document this.

2024-03-03  Colin Watson  <cjwatson@debian.org>

	Update syscall lists from systemd 85b774de49

	* lib/sandbox.c (make_seccomp_filter): Add `fchmodat2`.

	* NEWS.md: Document this.

2024-01-28  Colin Watson  <cjwatson@debian.org>

	return statements at end.
	(translate): Unpack `@_` first in a way that perlcritic recognizes.

2024-01-28  Colin Watson  <cjwatson@debian.org>

	Remove obsolete chconfig tool

	The FHS transition took place almost 25 years ago (at least in Debian),
	so it's not worth keeping this around now.

	* tools/chconfig: Remove.
	* tools/Makefile.am (dist_noinst_SCRIPTS): Remove chconfig.
	* tools/README: Likewise.
	* NEWS.md: Document this.

	man: enforce a single-column right margin

	Under groff, tbl consistently overruns the page width by one column,
	so accommodate this.

	Ref: https://gitlab.com/man-db/man-db/-/merge_requests/11#note_1708513108

	man: match the display width to the configured width

	Currently, the line length is:
	  if w ≤ 40: w - 2
	  else     : ⌊w*(39/40)⌋
	i.e.
	  if w ≤ 40: w - 2
	  else     : w - ⌈w/40⌉
	(this is equivalent to a ≤80 condition).

	This was originally originally introduced in commit
	f139e8273d5f3754f0d0dacb890e515b30c2d28b ("Add terminal line length
	 detection to man.") from 2001-06-28, which did
	  if w ∈ [66, 80]: 80    (via default)
	  else           : ⌊.9w⌋
	then tracked the default in
	commit cac2ef84fe626f112de7537c20dfe29c35a71b96 ("Update default
	 line length in line with groff 1.18.") from 2002-07-06,
	which updates it to the current formula,
	then commit 39cdee4ada59d711d066628ec827508070d90a70 ("Always pass a
	 line length to nroff") from 2023-08-06 removes any defaulting.

	This is ideologically quite weird, because this behaves like a
	stochastic best-effort fit so there is always a blank margin, growing
	with size, derived from a 21-year-old default which was only relevant
	because catpages were vaguely relevant, even though we perfectly
	know how large we need to display the manual by virtue of perfectly
	knowing the size of the teletype! There is no such margin on the
	left, and why would there be?

	Fixes Debian bug #1059537.

2023-12-28  наб  <nabijaczleweli@nabijaczleweli.xyz>

	man: simplify the right-margin condition

	As it stands, this is
	  ⌊line_length*(39/40)⌋ > line_length - 2
	which works out to
	  line_length ≤ 40
	Is that obvious? No (I analysed it to line_length < 80),
	but the way the result is used makes it equivalent to
	  line_length ≤ 80
	anyway.

	This currently blames to commit cac2ef84fe626f112de7537c20dfe29c35a71b96
	("Update default line length in line with groff 1.18.") dated
	2002-07-06 20:30:34 +0000(!) with a diff of
	  -       if (!troff && (line_length < 66 || line_length > 80))
	  -               return line_length * 9 / 10;
	  +       /* groff >= 1.18 defaults to 78. */
	  +       if (!troff && line_length != 80) {
	  +               int length = line_length * 39 / 40;
	  +               if (length > line_length - 2)
	  +                       return line_length - 2;

	In commit bbf7701c4f, 19 July, I got the sense of the tests that

	run groff's automated tests on them.

	Include .lf corrections in debugging output

	The pipeline command names in `PIPELINE_DEBUG` output are deliberately
	abbreviated in the cases where the command is inserting data into the
	`*roff` input stream, in an attempt to convey the essential parts
	without overwhelming the reader.  However, it probably does make sense
	to include `.lf` corrections there, since if you're relying on the
	debugging output to construct a manual shell pipeline when debugging an
	issue with a page, you'll want the `.lf` corrections so that line
	numbers still come out correctly.

2023-07-19  G. Branden Robinson  <g.branden.robinson@gmail.com>

	Improve lexgrog(1) portability

	This fixes a test failure in man1/lexgrog.1 when building against groff
	1.23.0.

	Borrow code from groff 1.23.0's "an-ext.tmac" file (licensed as
	permissively as a decadent society) to implement `EX` and `EE` extension
	macros from Ninth Edition Research Unix (1986) (and groff) to get
	monospaced code displays in a more portable way.  There is no way to
	portably change font families in pure man(7) itself, and the names of
	troff typefaces aren't very portable either.  There is also no portable
	way to test for the _existence_ of a font.  FTW.

	("Portable" here largely means "to AT&T device-independent troff
	implementations", for which there has been no official source since the
	mid-1990s.[1]  Several AT&T Unix System V licensees/descendants have
	continued to ship their own vendored versions, but these have enjoyed
	little or no development for the past 3 decades.)

	* Define a string `mC` to store the name of a presumed monospaced roman
	  typeface.  Use "CW", which is portable to AT&T device-independent
	  troff of the early 1980s before it occurred to anyone that Courier
	  might someday be available in italic and bold styles (and budget
	  available to purchase them).
	* Define `mC` as "CR" if using a typesetting device and the formatter is
	  groff, or claims groff compatibility by the setting the `.g` register.
	  This is reasonably portable to modern implementations given
	  traditional troff font naming practices and the pervasive influence of
	  Adobe Software and the "base fonts" of its PostScript and PDF
	  specifications.
	* If not typesetting (i.e., if using nroff), define `mC` as "R", which
	  is certain to be available.
	* Define `EX` and `EE` macros as groff does, if the formatter does not
	  set the `.g` register.
	* Migrate from `ft CW` and `nf` requests to `EX` macro calls.
	* Migrate from `ft P` and `fi` requests to `EE` macro calls.
	* Replace an inline use of `\f(CW` with a change to inline bold.  There
	  is to date no portable way to inline a font family change.

	Test passes now.  Tested as-is and with the `EX` and `EE` macro
	definitions forcibly enabled.

	spelling errors.

2022-10-18  Colin Watson  <cjwatson@debian.org>

	zsoelim_open_file: Fix use of uninitialized value

	In the case where `filename` has no directory part and does not contain
	a dot, we could reach the decision of whether to emit a "can't open %s"
	error message without initializing `decomp`.  Noticed by `gcc -Og`.

	* src/zsoelim.l (zsoelim_open_file): Initialize `decomp` to NULL.

	Fixes Debian bug #780235.

	* src/man.c (compare_candidates): Compare IDs before comparing sections.
	* NEWS.md: Document this.

2022-10-17  Colin Watson  <cjwatson@debian.org>

	Fixes https://gitlab.com/cjwatson/man-db/-/issues/8.

	* src/check_mandirs.c (ensure_db_open): Don't call `gripe_rwopen_failed`
	before returning false (since it only makes sense for one of the two
	callers).
	(testmandirs): Call `gripe_rwopen_failed` if `ensure_db_open` returns
	false.

2022-10-17  Colin Watson  <cjwatson@debian.org>

	Add 3type to default section list

	This is used by the Linux man-pages package, and should be lower
	priority than section 2.  Suggested by Alejandro Colomar.

	Fixes https://gitlab.com/cjwatson/man-db/-/issues/5.

	* include/manconfig.h (STD_SECTIONS): Add `3type` between sections `2`
	and `5`.

	* NEWS.md: Document this.

2022-10-15  Colin Watson  <cjwatson@debian.org>

	Release man-db 2.11.0

2022-10-13  Colin Watson  <cjwatson@debian.org>

	ult_src: Fix possible NULL dereference

	`gcc -fanalyzer` noticed that `canonicalize_file_name` can return NULL,
	therefore `find_include` could return NULL, and therefore it was
	possible for `ult_src` to attempt to dereference NULL in the `stat
	(base, &st)` call.  Push more work down to `find_include` so that we can
	consistently treat it as an error if it returns NULL.

	* src/ult_src.c (ult_softlink): Move error messages to ...
	(gripe_canonicalize_failed): ... here (new function).
	(find_include): Replace simple suffix globbing with `comp_file`, and use
	this approach in both the relative-to-mantree and
	relative-to-dirname-of-page cases; we previously only tried it in the
	latter case.  Call `gripe_canonicalize_failed` if the final
	canonicalization step fails; print a "can't resolve %s" error if we
	can't even find anything to canonicalize.
	(ult_src): Remove `comp_file` processing, now done by `find_include`.
	* src/ult_src.h (gripe_canonicalize_failed): Add prototype.
	* src/straycats.c (check_for_stray): Use `gripe_canonicalize_failed`.

2022-10-11  Colin Watson  <cjwatson@debian.org>

	Fix regression in preprocessor string handling

	We need to stop looking for characters that identify preprocessors after
	the first space or dash, as otherwise encoding declarations of the kind
	specified in man-recode(1) may break.

	* src/man.c (make_roff_command): Only consider the part of the
	preprocessor string up to the first space or dash, if any.

2022-10-11  Colin Watson  <cjwatson@debian.org>

	match_in_directory: Split into multiple functions

	`match_in_directory` had two almost entirely disjoint code paths, one
	for regex patterns and one for wildcard patterns; but its structure made
	it difficult for `gcc -fanalyzer` to understand that, and it was a bit
	unclear for humans too.  Split it up for clarity.

	* src/globbing.c (match_in_directory): Split out the
	regex/wildcard-handling parts to ...
	(match_regex_in_directory, match_wildcard_in_directory): ... here,
	respectively.

2022-10-11  Colin Watson  <cjwatson@debian.org>

	Assert that another xasprintf call returns non-NULL

	As with commit a22f140354c80a7c5c52c4a413f1c929e105a24c, `gcc
	-fanalyzer` notices that `xasprintf` can return NULL in some situations.
	I believe those situations would all amount to programming errors here,
	so add an assert.

	* src/mandb.c (main): Assert that `xasprintf` returns non-NULL.

2022-10-09  Colin Watson  <cjwatson@debian.org>

	Fix error message

	* src/straycats.c (check_for_stray): If canonicalizing `catdir` returns
	NULL, then substitute `catdir` into the "warning: %s is a dangling
	symlink" message, not `fullpath` (which at this point must be NULL).

2022-10-08  Colin Watson  <cjwatson@debian.org>

	Convert many more ints to bools

	I don't expect this to make a significant runtime difference, but it
	makes some things easier to analyse visually.

	Default to --disable-cache-owner on systems without getuid

	* m4/man-arg-cache-owner.m4 (MAN_ARG_CACHE_OWNER): If the system doesn't

	and issue a warning if `--enable-cache-owner` was given.

2022-10-07  Colin Watson  <cjwatson@debian.org>

	Fix build on systems without SIGPIPE

	* bootstrap.conf (gnulib_modules): Add sigpipe.
	* src/mandb.c (main): Drop `#ifdef SIGPIPE` guards, as Gnulib now
	ensures that it's defined.

2022-10-07  Colin Watson  <cjwatson@debian.org>

	Fix build on systems without getuid

	* lib/tempfile.c (running_setid): New function; always returns false if

	able to drop privileges either.

2022-10-07  Colin Watson  <cjwatson@debian.org>

2022-10-07  Colin Watson  <cjwatson@debian.org>

	Fix build on systems without SIGHUP

	* lib/cleanup.c (trap_abnormal_exits, untrap_abnormal_exits): Guard uses

2022-10-06  Colin Watson  <cjwatson@debian.org>

	Run preprocessors in the correct order

	We have no particular reason to trust the order of filters in a
	preprocessor string specified in a page; it's easy for authors to get
	this wrong by accident.  Do as groff(1) does and run them in a
	canonicalized order.

	Fixes Debian bug #1012078.

	* src/man.c (add_filter): New function, split out from
	`make_roff_command`.
	(make_roff_command): Iterate through possible preprocessors and add each
	one depending on whether it's present in the preprocessor string, rather
	than iterating through the preprocessor string and acting on each of its
	characters.  Turn several `int` variables into `bool` variables in
	passing.

	in practice identical but are semantically distinct.)

2022-10-02  Colin Watson  <cjwatson@debian.org>

	Reformat option declarations using macros

	The previous tabular presentation had some advantages, but it only

	mandb: Fully reorganize databases

	This allows us to produce bitwise-identical databases regardless of the
	order in which pages were scanned (at least with GDBM).
	`gdbm_reorganize` isn't enough for this, probably because entries end up
	in different positions in hash buckets depending on insertion order; but
	reading in the entire database and writing it back out in sorted order
	seems to do the job with negligible cost.

	Fixes Debian bug #1010957.

	* src/mandb.c (reorganize): New function: read all the items from a
	database in sorted order and write them back out.
	(mandb): Stop calling `MYDBM_REORG`, which saved space after deletions
	but didn't help with reproducibility.
	(process_manpath): Call `reorganize` if any changes were made to a
	database.
	* libdb/mydbm.h (MYDBM_REORG): Remove macro.
	* NEWS.md: Document this.

	mandb: Rearrange database path operations

	Moving these into "methods" of `struct dbpaths` makes the control flow
	clearer by avoiding lots of inlined `#ifdef`s.

	I fixed a possible crash in `mandb -f` in the process, exposed by the
	clearer control flow.

	* src/mandb.c (dbpaths_init, dbpaths_copy_to_tmp, dbpaths_remove_tmp):
	New functions.
	(finish_up): Rename to ...
	(dbpaths_rename_from_tmp): ... this.
	(do_chown): Rename to ...
	(dbpaths_chown_if_possible): ... this.
	(cleanup_sigsafe): Rename to ...
	(dbpaths_unlink_tmp): ... this, and take a `struct dbpaths *` argument
	rather than `void *`.
	(cleanup): Rename to ...
	(dbpaths_free_elements): ... this, and take a `struct dbpaths *`
	argument rather than `void *`.
	(mandb, process_manpath): Use new `dbpaths_*` functions.  Only call
	`dbpaths_rename_from_tmp` if `run_mandb` is set (in practice this was
	always true anyway but this makes it clearer).  Only call
	`dbpaths_chown_if_possible` if `run_mandb` is set and
	`dbpaths_rename_from_tmp` was called (this may have caused a crash in
	some edge cases involving `mandb -f`).

2022-10-01  Colin Watson  <cjwatson@debian.org>

	test_manfile: Remove "already exists" check

	This produced inconsistent results in some unusual cases.  For example,
	if `/usr/share/man/man5/inetd.conf.5.gz` was a symlink to
	`/usr/share/man/man8/inetd.8.gz` and had `NAME` entries for both `inetd`
	and `inetd.conf`, then if `inetd.8.gz` was scanned first we would
	include a `WHATIS_MAN` entry in section 8 for `inetd.conf`, while if
	`inetd.conf.5.gz` was scanned first we'd skip that due to hitting the
	already-exists check when scanning `inetd.8.gz`.

	This was originally a performance optimization.  Now that we cache the
	results of `ult_src` and `find_name`, this optimization no longer helps
	us much, so it can go.

	* src/check_mandirs.c (test_manfile): Don't return early if the page
	already exists with matching details.
	* NEWS.md: Document this.

2022-10-01  Colin Watson  <cjwatson@debian.org>

	Further improve name selection for whatis targets

	In commit 9aff3c30b0, I used the rule "first name in the trace out of
	those that have the best ID".  However, a better rule turns out to be to
	pick the last entry in the trace that has the same section and extension
	as the starting page.  This is already guaranteed to have at least as
	good an ID as the starting page, and since whatis pointers don't include
	the target section and extension we need to ensure that they don't cross
	sections/extensions; otherwise we just end up with database entries that
	man(1) refuses to use, which isn't particularly useful.

	* src/descriptions_store.c (store_descriptions): Parse and cache all the
	filenames in the trace at the start.  Use the last entry in the trace
	with the same section/extension as the starting page as the pointer for
	`WHATIS_*` entries.

2022-10-01  Colin Watson  <cjwatson@debian.org>

	test_manfile: Stop caching ult_src traces

	Now that `test_manfile` always calls `ult_src` before adding database
	entries, there's no need for it to cache the resulting traces, and doing
	so had some confusing consequences since `store_descriptions` could end
	up seeing cached traces that didn't include the initial path.

	* src/check_mandirs.c (struct whatis): Remove `trace` element.
	(whatis_free): Stop freeing `whatis->trace`.
	(test_manfile): Stop caching `ult->trace`; pass it directly to
	`store_descriptions` instead.

2022-10-01  Colin Watson  <cjwatson@debian.org>

	Restructure ult_src to add caching

	* src/ult_src.c (struct ult_key): New structure.
	(ult_key_new, ult_key_equals, ult_key_hash, ult_key_free, ult_value_new,
	ult_value_free): New functions.
	(ult_cache): New map.
	(ult_src): Instead of returning a path as a string and taking `trace` as
	an output parameter, return a `struct ult_value *` containing both path
	and trace.  Cache the return value in a hash map (indexed by a composite
	key consisting of `name` and `flags`), and return cached values where
	possible rather than repeating the same work.  Update all callers to
	reflect the new signature.
	* src/ult_src.h (struct ult_value): New structure.
	(ult_src): Update prototype.

	* src/check_mandirs.c (test_manfile): Simplify `ult_src` calling
	arrangements now that repeated calls with the same `name` and `flags`
	arguments are cheap.  At the moment this may end up doing a little more
	work in some rare cases (links to already-scanned pages with `.so`
	links), but that doesn't seem to be very significant at the moment, and
	caching could be improved inside `ult_src` if it proves to be a problem.
	* src/descriptions_store.c (store_descriptions): `trace` is now always
	set.  Add an assertion of this and drop a couple of conditionals.

2022-09-25  Colin Watson  <cjwatson@debian.org>

	ult_src: Remove recursion

	The use of recursion for `.so` handling in `ult_src` is somewhat
	inconvenient, and it's relatively easy to convert it to an iterative
	implementation.

	There should be no functional change from this commit, except to some
	details of debug messages.

	* src/ult_src.c (find_include_directive): New function, extracted from
	`ult_src`.
	(ult_src): Handle `.so` links using a loop rather than recursion.  Check
	for compression extensions towards the end of the loop rather than at
	the beginning, to avoid nonexistent files showing up in the trace.

2022-09-25  Colin Watson  <cjwatson@debian.org>

	mandb: Improve debugging

	* src/check_mandirs.c (test_manfile): Log the file under consideration
	on entry.  Log when we return early due to an existing database entry.
	Remove some unnecessary parentheses from debug messages.
	* src/ult_src.c (ult_src): Remove leading newline from debug message.

2022-09-25  Colin Watson  <cjwatson@debian.org>

	Don't skip adding a database entry due to SO_MAN

	An existing `SO_MAN` entry shouldn't stop us considering a page for
	insertion into the database, because until we run `ult_src` we don't yet
	know whether that page will be `ULT_MAN` (which should replace the
	existing entry) or `SO_MAN` (which shouldn't).

	* src/check_mandirs.c (test_manfile): Don't return early due to an
	existing matching `SO_MAN` entry, but only due to an `ULT_MAN` entry.
	* NEWS.md: Document this.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Fix section/extension for whatis entries in database

	* src/descriptions_store.c (store_descriptions): Use the
	section/extension of the best name for whatis entries, since we don't
	have anything better.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	store_descriptions: Improve debugging

	* src/descriptions_store.c (store_descriptions): Log the extension of
	each entry being stored.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Extend database entry replacement rules

	These rules were previously ambiguous such that the targets of whatis
	entries depended on the order in which files were scanned.

	* libdb/db_store.c (enum replace_action): Add.
	(replace_if_necessary): Extend rules for greater stability.  We now also
	take mtimes and pointers into account, as well as including a case for
	when the new ID is weaker than the old one (there was already a case for
	when it was stronger).
	(dbstore): Use `replace_if_necessary` when considering replacing multi
	keys.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Fix section/extension for links in database

	In some cases this resulted in spurious database entries.  For example,
	if `man5/inetd.conf.5` was a symlink to `man8/inetd.8` and that page had
	a `NAME` entry for `inetd`, then as well as entries for `inetd` in
	section 8 and `inetd.conf` in section 5, we would also store a spurious
	entry for `inetd` in section 5.  We no longer do that.

	* src/descriptions_store.c (store_descriptions): For names corresponding
	to entries in the ultimate source trace and not to the base name of the
	file, use the section and extension of the trace entry rather than of
	the ultimate source.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Pick a more consistent name for whatis targets

	We don't want the targets of whatis entries in the database to depend on
	the order in which files were scanned.  Prefer the first name in the
	trace out of those that have the best ID.

	* src/descriptions_store.c (store_descriptions): Defer adding names that
	don't appear in the ultimate source trace (i.e. whatis entries) until we
	know the best name to use as the target, and use that best name as the
	pointer for each of them.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Fix stored ID for links

	Database entries for links were often incorrectly stored as `ULT_MAN`,
	depending on the exact order in which pages were scanned.  They are now
	stored more consistently as `SO_MAN`.

	* src/descriptions_store.c (store_descriptions): Override the ID from
	`ULT_MAN` to `SO_MAN` if the name is not the last entry in the trace.
	(Previously we overrode from `SO_MAN` to `ULT_MAN` if the name was the
	last entry in the trace, but not the converse.)
	* NEWS.md: Document this.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Simplify struct mandata memory allocation

	The arrangement where most of the fields of `struct mandata` were
	constant pointers into the `addr` field was a bit more memory-efficient,
	but it made some kinds of analysis and reorganization very difficult,
	and we don't actually need to be quite that frugal about memory.
	Reorganize this to allocate each field independently instead.

	* lib/filenames.c (filename_info): Allocate each field independently.
	Use Gnulib's `base_name` and `dir_name` functions to parse paths.  Stop
	setting `info->addr`.
	(free_mandata_struct): Free the `ext`, `sec`, `pointer`, `comp`,
	`filter`, and `whatis` fields.  Stop freeing `addr`.
	* lib/filenames.h (struct mandata): Remove `addr`.  Make `ext`, `sec`,
	`pointer`, `comp`, `filter`, and `whatis` non-`const`.
	* libdb/db_lookup.c (split_content): Copy the `ext`, `sec`, `pointer`,
	`filter`, `comp`, and `whatis` fields.  Stop setting `addr`.
	* libdb/db_store.c (make_content): Copy the `pointer`, `comp`, `filter`,
	and `whatis` fields.
	* src/descriptions_store.c (store_descriptions): Copy `pointer` and
	`whatis` fields.
	* src/straycats.c (check_for_stray): Copy `comp`, `ext`, `sec`, and
	`filter` fields.

	* libdb/db_lookup.c (dblookup): Always free `cont`'s data pointer, since
	it's no longer sometimes borrowed.
	* libdb/db_store.c (dbstore): Free `cont`'s and `oldcont`'s data
	pointers, since they're no longer borrowed.
	* src/check_mandirs.c (purge_missing): Free `content`'s data pointer,
	since it's no longer borrowed.

	* libdb/db_lookup.c (dblookup_pattern): Stop freeing `info->addr`.
	* src/catman.c (parse_for_sec): Stop freeing `entry->addr`.
	* src/whatis.c (do_apropos): Stop freeing `info->addr`.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Stop using the addr field of struct mandata

	The `addr` field of `struct mandata` is just intended as an internal
	buffer, but some functions were extracting information from it in
	complicated ways, which made it difficult to refactor the memory
	allocation here.  Use different approaches.

	* src/check_mandirs (test_manfile): Calculate `len` using `comp_info`.
	This duplicates some of what `filename_info` does, but it's just some
	cheap string manipulation, and it expresses what we want in a less
	confusing way (the length of the file name with any compression
	extension removed).
	* src/descriptions_store.c (store_descriptions): Check whether `path` is
	a prefix of `trace_name` rather than of `trace_info->addr`.
	`trace_info->addr` is always itself a prefix of `trace_name`, so if
	`path` is not a prefix of `trace_name` then it can't be a prefix of
	`trace_info->addr`.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	is_prefix: Improve parameter naming

	The second parameter doesn't have to be a directory, so stop implying
	that in the parameter name.

	* src/descriptions_store.c (is_prefix): Rename `path` to `parent`; rename
	`dir` to `child`.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Simplify split_content interface

	Now that `struct mandata` is always allocated on the heap, we might as
	well just have `split_content` return a freshly-allocated `struct
	mandata` rather than taking a pointer to one as a parameter.

	* libdb/db_lookup.c (split_content): Allocate and return a `struct
	mandata`; remove `pinfo` parameter.  Update all callers.
	* libdb/db_storage.h (split_content): Update prototype.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	Always allocate struct mandata on the heap

	This means we no longer need two slightly different functions for
	freeing it.

	* libdb/db_lookup.c (dblookup_pattern): Allocate `struct mandata` on the
	heap.  Simplify arrangements for adding to the `infos` list.
	(dbstore): Allocate `struct mandata` on the heap.
	* src/catman.c (parse_for_sec): Likewise.
	* src/check_mandirs.c (purge_pointers, purge_missing): Likewise.
	* src/straycats.c (check_for_stray): Likewise.
	* src/whatis.c (do_apropos): Likewise.

	* lib/filenames.c (free_mandata_elements): Remove function and move its
	contents to ...
	(free_mandata_struct): ... here, if `pinfo` is set.
	* lib/filenames.h (free_mandata_elements): Remove prototype.

2022-09-24  Colin Watson  <cjwatson@debian.org>

	filename_info: Always allocate info->name

	Only one call site has any interest in this being unset (in order to
	pass the result to `dbstore`), and even there it's easier for the caller
	to deal with unsetting it.  Otherwise, it's strictly more convenient if
	the structure returned by `filename_info` always includes the name of
	the page.

	* lib/filenames.c (filename_info): Remove `req_name` parameter; update
	all callers.  Always set `info->name` before returning successfully.
	* lib/filenames.h (filename_info): Update prototype.
	* src/check_mandirs.c (test_manfile): Use `info->name` for
	`manpage_base` rather than poking around in `info->addr`.
	(count_glob_matches): Remove `name` parameter; update all callers.
	* src/descriptions_store.c (store_descriptions): Drop now-unnecessary
	check for `trace_info->name`.
	* src/man.c (do_global_apropos_section): Build `title` using
	`info->name` rather than poking around in `info->addr`.
	* src/mandb.c (update_one_file): Drop now-unnecessary check for
	`info->name`.

2022-09-23  Colin Watson  <cjwatson@debian.org>

	Reduce indentation in store_descriptions a bit

	* src/descriptions_store.c (store_descriptions): Use an early-continue
	construction to save a level of indentation.

2022-09-23  Colin Watson  <cjwatson@debian.org>

	Simplify the filename_info interface

	This interface is a bit less confusing.

	* libdb/db_lookup.c (free_mandata_elements, free_mandata_struct): Move
	to ...
	* lib/filenames.c (free_mandata_elements, free_mandata_struct): ...
	here.
	* libdb/db_storage.h (free_mandata_elements, free_mandata_struct): Move
	to ...
	* lib/filenames.h (free_mandata_elements, free_mandata_struct): ...
	here.

	* lib/filenames.c (filename_info): Return a `struct mandata` with the
	`addr` element set to the buffer containing the fields, rather than
	returning the buffer and taking a pointer to a `struct mandata` as a
	parameter.  Update all callers.
	* lib/filenames.h (filename_info): Update prototype.

2022-09-23  Colin Watson  <cjwatson@debian.org>

	Move manual page file name utilities to lib/

	* src/filenames.c: Move to ...
	* lib/filenames.c: ... here.
	* src/filenames.h: Move to ...
	* lib/filenames.h: ... here.  Update positioning of all includes.
	* lib/Makefile.am (libman_la_SOURCES): Add `filenames.c` and
	`filenames.h`.
	* src/Makefile.am (man_recode_LDADD): Link with `$(LIBMAN)` instead of
	`$(LIBMANDB)`.
	(lexgrog_SOURCES, man_SOURCES, mandb_SOURCES): Remove `filenames.c` and
	`filenames.h`.
	* po/POTFILES.in: Rename `src/filenames.c` to `lib/filenames.c`.

	* lib/filenames.c (gripe_bogus_manpage): Remove `quiet < 2` condition.
	(filename_info): Add `warn_if_bogus` parameter; only call
	`gripe_bogus_manpage` if it is set.  Update all callers.
	* lib/filename.h (filename_info): Update prototype.

	* libdb/db_storage.h (struct mandata): Move to ...
	* lib/filenames.h (struct mandata): ... here.  Add includes where
	necessary.

2022-09-23  Colin Watson  <cjwatson@debian.org>

	Fix distcheck

	* po/POTFILES.in: Rename `src/compression.c` to `lib/compression.c`.

2022-09-23  Colin Watson  <cjwatson@debian.org>

	Move compression file name utilities to lib/

	This makes more sense as a home for plain file name manipulation
	utilities.  I also merged `include/comp_src.h.in` into
	`lib/compression.c`, because structure definitions (as opposed to
	declarations) don't belong in header files.

	* src/compression.c: Move to ...
	* lib/compression.c: ... here.  Remove unnecessary `pipeline.h` include.
	* src/compression.h: Move to ...
	* lib/compression.h: ... here.  Update positioning of all includes.
	* lib/Makefile.am (libman_la_SOURCES): Add `compression.c` and
	`compression.h`.
	* lib/README: Add `compression.*`.
	* src/Makefile.am (lexgrog_SOURCES, man_SOURCES, man_recode_SOURCES,
	mandb_SOURCES): Remove `compression.c` and `compression.h`.

	* include/comp_src.h (comp_list): Move to ...
	* lib/compression.c (comp_list): ... here.  Update all references.
	* include/manconfig.h (struct compression, comp_list): Move to ...
	* lib/compression.h (struct compression, comp_list): ... here.  Add
	includes where necessary.
	* Makefile.am (noinst_HEADERS): Remove `include/comp_src.h`.

2022-09-23  Colin Watson  <cjwatson@debian.org>

	Remove infoalloc macro

	It doesn't really pull its weight.

	* libdb/db_lookup.c (dblookup, dblookup_pattern): Call `XZALLOC (struct
	mandata)` rather than `infoalloc ()`.
	* src/man.c (try_section, do_global_apropos_section): Likewise.
	* libdb/db_storage.h (infoalloc): Remove.

2022-09-19  Colin Watson  <cjwatson@debian.org>

	Maintain multi key references in sorted order

	This is a step towards being able to reproduce the same database given
	the same manual page tree.

	* bootstrap.conf (gnulib_modules): Add stpcpy.
	* libdb/db_lookup.c (name_ext_equals): Remove static; add pure
	attribute.
	(name_ext_compare): New function.
	(list_extensions): Add entries in sorted order.
	* libdb/db_storage.h (name_ext_equals, name_ext_compare): Add
	prototypes.
	* libdb/db_store.c (make_extensions_reference): New function.
	(dbstore): When building or updating multi key references, maintain them
	in sorted order.
	* NEWS.md: Document this.

2022-09-19  Colin Watson  <cjwatson@debian.org>

	Remove some excessive debugging output

	This hasn't been of any practical use for many years.

	* lib/security.c (drop_effective_privs, regain_effective_privs): Remove
	debug messages emitted when increasing or decreasing the privilege drop
	count.

2022-08-11  Colin Watson  <cjwatson@debian.org>

	Fix use of pointer (address only) after free

	I don't believe this was technically undefined behaviour, since we
	didn't actually dereference the dangling pointer, merely compared its
	value (the pointer address itself) against entries in the cleanup stack.
	However, the compiler probably had a hard time proving that, so the
	use-after-free warning issued by recent versions of GCC seems fair
	enough.

	* src/mandb.c (cleanup): Don't free dbpaths.
	(process_manpath): Free it here instead, after calling pop_cleanup.

2022-08-11  Colin Watson  <cjwatson@debian.org>

	Make CATWIDTH override MINCATWIDTH/MAXCATWIDTH

	Otherwise setting `CATWIDTH` to something larger than 80 confusingly
	doesn't work unless you also set `MAXCATWIDTH`.

	Fixes https://gitlab.com/cjwatson/man-db/-/issues/9.

	* src/man.c (add_roff_line_length): Skip terminal width range check if
	`cat_width` is set.
	* man/man5/manpath.man5 (FORMAT): Remove note that `CATWIDTH` should be
	within the range set by `MINCATWIDTH` and `MAXCATWIDTH`, and instead say
	that it overrides them.
	* NEWS.md: Document this.

	Add more case variants of localized versions of NAME

	Stop GitLab from getting confused about licences

	GitLab uses https://github.com/licensee/licensee to detect the project's
	licence, and if that finds multiple matching files then it throws up its
	hands and refuses to make a licence assertion, with no apparent way to
	override it.

	To avoid this problem, move the secondary licence files (those that
	apply only to some files, rather than to the project as a whole) back
	into a subdirectory, so that `licensee` doesn't notice them.

	* COPYING.GPLv2: Move to ...
	* docs/COPYING.GPLv2: ... here.  Update all references.
	* COPYING.LIB: Move to ...
	* docs/COPYING.LIB: ... here.  Update all references.

	Clarify effective GPLv3 licensing

	While man-db's own files are individually licensed under GPLv2 (or in a
	few cases LGPLv2.1), the project as a whole is effectively GPLv3 due to
	Gnulib.  This was already explained in README.md, but make it a bit
	clearer by having the top-level COPYING file be a copy of GPLv3.

	* COPYING: Move to ...
	* COPYING.GPLv2: ... here.
	* COPYING: New file.
	* Makefile.am (dist_noinst_DATA): Add COPYING.GPLv2.

	Recognize another Turkish translation of NAME

	Emir SARI reports that "AD" is the de facto standard technical
	terminology for "NAME" in Turkish, rather than "İSİM" which sounds
	slightly colloquial.  Recognize it as well.

2022-03-08  Colin Watson  <cjwatson@debian.org>

	pre-commit: Add shellcheck

	* .pre-commit-config.yaml: Add shellcheck.  We need separate hooks for

2022-03-08  Colin Watson  <cjwatson@debian.org>

	Refactor use of cd in shell scripts

	shellcheck warns about unchecked uses of `cd` (SC2164).  Either check it
	or refactor to avoid changing directory.

	* src/tests/man-deleted-directory: Check `cd` call.
	* src/tests/man-suffixed-extension: Avoid changing directory.
	* tools/mkcatdirs: Likewise.

2022-03-08  Colin Watson  <cjwatson@debian.org>

	mkcatdirs: Skip nonexistent man directories

	* tools/mkcatdirs: `manpath -qg` may return man directories that are
	mentioned in the configuration file but that don't exist on the
	filesystem.  Skip these.

2022-03-08  Colin Watson  <cjwatson@debian.org>

	mkcatdirs: Refactor using install(1)

	I'm not sure this script is widely-used, but it might as well work.  It
	previously relied on `mkinstalldirs`, which is a build tool not
	typically installed on end-user systems.

	* tools/mkcatdirs: Refactor cat directory creation using install(1).

2022-03-08  Colin Watson  <cjwatson@debian.org>

	Apply various minor shell syntax improvements

	* manual/print-options: Explicitly set `LANGUAGE=''` rather than
	`LANGUAGE=`, pacifying shellcheck SC1007 which notes that this
	construction might otherwise be misread.
	* src/tests/manconv-odd-combinations: Use `printf %b` to pacify
	shellcheck SC2059.
	* src/tests/testlib.sh: Tell shellcheck which shell syntax to assume,
	since this file has no `#!` line.
	(run): Disable shellcheck SC2154; `abs_top_builddir` is always set by
	the test runner.
	(report): Remove unnecessary `$` before variable in arithmetic context.
	(tools/checkman): Use `$(...)` for command substitution.  Quote
	variables properly where possible, and ignore shellcheck SC2068 in a
	couple of other places.

2022-03-07  Colin Watson  <cjwatson@debian.org>

	tests: Pacify shellcheck SC2188

	The previous construction resulted in:

	  SC2188 (warning): This redirection doesn't have a command. Move to its
	  command (or use 'true' as no-op).

	* src/tests/man-mandatory-manpath, src/tests/testlib.sh: Avoid
	redirections without a command.

2022-03-07  Colin Watson  <cjwatson@debian.org>

	tests: Make pass/fail reporting more shellcheck-friendly

	* src/tests/testlib.sh (report): New function, similar to expect_pass

	man(1): Fix override dir handling

	Previously, override dir was affecting only some cases of manpath
	determination.  Apply it only when all paths have been gathered instead.

	Also look for override dir when sorting candidates.

	Fixes src/tests/man-override-dir failing when --with-override-dir=od is
	passed to ./configure.

	[cjwatson: Refactored candidate comparison to use a strcmp-style
	function, and simplified the addition of override directories a little
	more.]

	* src/man.c (compare_override_dir): New function.
	(compare_candidates): Compare override directory status between
	comparing section extensions and comparing locale elements.
	* src/manp.c (insert_override_dir): Remove.
	(get_manpath_from_path, add_man_subdirs): Remove calls to
	insert_override_dir.

	Add some hardening options to the systemd service

	Based on a patch by Johannes Segitz in the openSUSE packaging, although
	I added `PrivateTmp=true` and `LockPersonality=true` as well.

	Fix showing HTML, as firefox runs into background too fast

	[cjwatson: I'm not 100% keen on this approach, since it randomly depends
	on how long the browser happens to take to launch and might be a bit
	annoying for users of light browsers such as w3m, but there doesn't seem
	to be any other good alternative for the more common case of people
	using typical graphical browsers.]

	Fixes Debian bug #335411 and Savannah bug #59542.

	* src/man.c (format_display): Sleep for a few seconds after starting the
	browser, since it may background itself before loading files.
	* NEWS.md: Document this.

2022-02-08  Colin Watson  <cjwatson@debian.org>

	Fix building on Cygwin

	Achim reported that 2.10.0 no longer builds on Cygwin, while 2.9.4 did.
	This was magnificently obscure, at least to this Unix-head.  Initially
	it appeared to be an issue with inter-library linking between libman and
	libmandb, but 2.9.4 relied on that too, just slightly less so.

	The actual problem was that libman only exported
	`gl_get_setlocale_null_lock` and not all the other symbols it's supposed
	to export, which is because that was explicitly marked for export and no
	other symbols were.  Building libman with `-Wl,--export-all-symbols`
	fixes this; libman is intended as an aggregation of various helper
	functions, including those from Gnulib, and it doesn't make sense to be
	especially selective since it's only installed as a private library
	anyway.

	(I'm still not exactly sure why 2.9.4 didn't do the same thing, but this
	seems to be a good enough fix.)

	* configure.ac: Set LIBMAN_EXPORT_LDFLAGS to '-Wl,--export-all-symbols'
	when linking with GNU ld on Windows platforms.
	* lib/Makefile.am (libman_la_LDFLAGS): Add $(LIBMAN_EXPORT_LDFLAGS).
	* src/Makefile.am (LIBMAN): Remove $(top_builddir)/gl/lib/libgnu.la; as
	a convenience library, this is already incorporated into libman.la, and
	specifying it again causes multiple-definition errors on Cygwin.
	* src/tests/Makefile.am (get_mtime_LDADD): Likewise.
	* NEWS.md: Document this.

	* src/man.c (make_roff_command, make_display_command): Likewise.

	Revert "Reduce indentation depth using C99"

	This reverts commit c4d20840f3487588c4a0da4397b1acb6dc83a1e5.  Even in
	C99, a declaration isn't valid immediately after a label; this didn't
	become valid until C2x, although gcc allows it as an extension.

	Fixes https://gitlab.com/cjwatson/man-db/-/issues/2.

2022-01-31  Colin Watson  <cjwatson@debian.org>

	man: Avoid spurious error messages due to subpages

	Since man-db 2.4.2, `man` has behaved as if the `-l` option was given if
	a manual page argument contains a slash.  Since man-db 2.5.6, this has
	interacted slightly poorly with the subpage feature, emitting spurious
	error messages if given multiple manual page arguments some of which
	include a slash.  `man` no longer emits spurious error messages in this
	case.

	Fixes Savannah bug #53708.

	* src/man.c (man): Move name-contains-slash case to ...
	(man_maybe_local): ... here (new function).
	(main): Call man_maybe_local instead of man where checking for names
	containing slashes is acceptable.
	* NEWS.md: Document this.

	mandb: Fix handling of link target mtimes

	Depending on directory iteration order, mandb sometimes incorrectly
	stored the mtime of a symlink as the mtime of its target as well.

	Fixes Debian bug #691643.

	* src/descriptions_store.c (store_descriptions): When adding entries
	based on an ult_src trace, use the mtime of the target file if possible
	rather than the mtime of the base entry.
	* src/tests/Makefile.am (ALL_TESTS): Add mandb-symlink-target-timestamp.
	* src/tests/get-mtime.c (main): Use lstat rather than stat.

2022-01-30  Colin Watson  <cjwatson@debian.org>

	Simplify static analysis of fatal errors

	The usual idiom for fatal error reporting in man-db 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 `_Noreturn`

	mandb: Don't modify DB without changing its mtime

	In d9ebedad15 (man-db 2.7.0), mandb started relying on the modification
	times of database files themselves rather than using a special row, in
	order to make databases reproducible between otherwise-identical
	installations (subject to predictable behaviour from the underlying
	database).

	There was a difficulty with this change.  Because purging deleted pages
	from the database opened and closed the database in a separate phase
	before the main phase of looking for updated manual pages, and because
	the main phase relies on comparing against the mtime of the database to
	find changed files, I had to arrange to restore the original mtime at
	the end of the purge phase in order to avoid confusing the main phase
	into being a no-op.  However, in some cases (perhaps due to other bugs,
	but nevertheless), it's possible for the purge phase to find work to do
	without the main phase ever finding any modified directories, which
	meant that the net effect of mandb would be to modify its database
	without changing its mtime.  This is bad form, and confused some backup
	systems into believing that the filesystem had been corrupted, since
	files having their contents changed without updating their mtime is
	indeed a likely symptom of filesystem corruption.

	To avoid this, restructure our database-handling code so that a given
	mandb run opens any given database at most once.  This means that we no
	longer need to modify mtimes manually, so the usual filesystem rules
	apply.

	Fixes Debian bug #1004355 and Ubuntu bug #1411633.

	Significantly improve mandb performance

	Forking large numbers of subprocesses is slow.  An ideal fix would
	involve work in libpipeline (e.g. generator functions or
	multithreading), but in the meantime we can do much better in the common
	case of moderately-sized pages compressed using zlib by doing in-process
	decompression.  On my test system, this takes `mandb -c` from 344
	seconds (or 152 seconds with `MAN_DISABLE_SECCOMP=1` before 50200d151d,
	or 78 seconds with `MAN_DISABLE_SECCOMP=1` after 50200d151d) to 10

	to implement decompression in some other way.

	Since it's only used by one function, and not all of man-db's tools need
	libpipeline in their own right (e.g. accessdb), it seems worth pushing
	this up a layer.

	* lib/encodings.c (struct conversion_entry, conversion_table,
	convert_encoding, check_preprocessor_encoding): Move to ...
	* src/manconv.c: ... here.
	* lib/encodings.h (check_preprocessor_encoding): Move to ...
	* src/manconv.h: ... here.
	* lib/Makefile.am (libman_la_CPPFLAGS): Remove $(libpipeline_CFLAGS).
	(libman_la_LDFLAGS): Remove $(libpipeline_LIBS).
	* src/man-recode.c, src/man.c, src/manconv.c: Include manconv.h.

2022-01-17  Colin Watson  <cjwatson@debian.org>

	Pacify cppcheck in check_preprocessor_encoding

	* lib/encoding.c (check_preprocessor_encoding): Explicitly initialize
	directive_end and ppsearch.  If directive is non-NULL by the time these
	are used then they're always initialized, but cppcheck didn't manage to
	spot that.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Update to Gnulib 20220116

	* bootstrap: Sync to Gnulib 1eae0f7ea3c220d054025f2c9211700665f9f4a0.
	* bootstrap.conf (GNULIB_REVISION): Set to
	1eae0f7ea3c220d054025f2c9211700665f9f4a0.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Move some more declarations out of manconfig.h

	Header includes should be in the same translation unit as the code that
	uses them rather than being ambient across the whole project.

	* include/manconfig.h: Remove obsolete header comment about program
	paths.

	* include/manconfig.h: Remove includes of "xvasprintf.h", <stddef.h>,
	"xalloc.h", and "xstrndup.h", as well as "struct pipeline" declaration.
	Update all files that relied on these to include/declare them directly
	instead as needed.

	* include/manconfig.h (MAN_DB, mkdbname): Move to ...
	* libdb/mydbm.h: ... here.

2022-01-16  Colin Watson  <cjwatson@debian.org>

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Use lexgrog type definitions consistently

	* include/manconfig.h (MANPAGE, CATPAGE): Move to ...
	* src/lexgrog.h (MANPAGE, CATPAGE): ... here.
	* src/lexgrog.l (find_name, find_name_decompressed): Compare p_lg->type
	against CATPAGE rather than testing its truth value.
	* src/lexgrog_test.c (main): Set type to MANPAGE/CATPAGE rather than
	0/1.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Update translation files

	* po/man-db.pot, po/*.po: Update.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Fix build system following changes to include/*.h

	* Makefile.am (noinst_HEADERS): Add include/comp_src.h and
	include/manconfig.h.
	* lib/Makefile.am (libman_la_CPPFLAGS): Replace
	-I$(top_builddir)/include with -I$(top_srcdir)/include.
	* libdb/Makefile.am (libmandb_la_CPPFLAGS): Likewise.
	* src/Makefile.am (AM_CPPFLAGS): Likewise.
	* src/tests/Makefile.am (AM_CPPFLAGS): Likewise.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Remove Checker support

	The GNU Checker package was last released in 2005, and its web page
	(https://www.gnu.org/software/checker/) says that it has been
	decommissioned in favour of Valgrind.

	* include/manconfig.h (chkr_garbage_detector): Remove.
	* src/man.c (main): Remove call to chkr_garbage_detector.
	* src/mandb.c (main): Likewise.
	* src/whatis.c (search): Likewise.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Remove obsolete include/README

	* include/README: Remove; it claimed that this directory contains files
	created by configure, which is no longer true, and it said nothing else
	useful.
	* Makefile.am (dist_noinst_DATA): Remove include/README.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Stop generating include/*.h from configure

	This was inconvenient when making changes to those central header files.
	All `configure`-generated preprocessor symbols are now in `config.h`.

	* configure.ac: Define various PROG_* symbols.  Remove AC_SUBST calls
	for compressors and decompressors.
	(AC_CONFIG_FILES): Remove include/comp_src.h and include/manconfig.h.
	* m4/man-arg-override-dir.m4: Define OVERRIDE_DIR symbol.

	* README.md: Update references to include/manconfig.h.
	* .gitignore: Remove include/*.h.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Rename program preprocessor symbols to PROG_*

	This is mainly in order to avoid potential confusion with `PIC` (defined
	when building position-independent code), but I renamed all these
	variables for consistency.

	* include/manconfig.h.in (PAGER, CAT, WEB_BROWSER, TR, GREP, TROFF,
	NROFF, EQN, NEQN, TBL, COL, VGRIND, REFER, GRAP, PIC, COMPRESSOR,
	GUNZIP, UNCOMPRESS, BUNZIP2, UNLZMA, UNXZ, LZIP, UNZSTD): Rename to ...
	(PROG_PAGER, PROG_CAT, PROG_BROWSER, PROG_TR, PROG_GREP, PROG_TROFF,
	PROG_NROFF, PROG_EQN, PROG_NEQN, PROG_TBL, PROG_COL, PROG_VGRIND,

	PROG_UNCOMPRESS, PROG_BUNZIP2, PROG_UNLZMA, PROG_UNXZ, PROG_LZIP,
	PROG_UNZSTD): ... these (respectively).  Update all references.

2022-01-16  Colin Watson  <cjwatson@debian.org>

	Move lexgrog-related bits out of manconfig.h

	It's generally cleaner for things like this to be in a dedicated header
	file.

	* include/manconfig.h.in (struct lexgrog, find_name,
	find_name_decompressed): Move to ...
	* src/lexgrog.h: ... here (new file).  Simplify declarations slightly.
	* include/manconfig.h.in (lexgrog filter enum): Move to ...
	* src/lexgrog.l: ... here.
	* src/Makefile.am (lexgrog_SOURCES, mandb_SOURCES): Add lexgrog.h.
	* src/check_mandirs.c, src/lexgrog.l, src/lexgrog_test.c,
	src/straycats.c: Include lexgrog.h.

2022-01-03  Colin Watson  <cjwatson@debian.org>

	Reduce overhead of MAN_DISABLE_SECCOMP=1

	If MAN_DISABLE_SECCOMP=1 is set (or if seccomp is otherwise
	unavailable), then there's no need to call seccomp_init and friends,
	which can have significant overhead even if we never actually load the
	resulting filter.

	Pointed out by Steinar H. Gunderson in https://bugs.debian.org/1003089.

	* lib/sandbox.c (make_seccomp_filter): Return NULL early if
	can_load_seccomp returns false.
	(_sandbox_load): Return early if the relevant context is NULL.
	(sandbox_free): Only call seccomp_release if the relevant context is
	non-NULL.

	Add release automation

	When a tag is pushed to GitLab, upload the bootstrapped source tarball
	to the package registry, and create a release in GitLab associated with
	the tag.

	* .gitlab-ci.yml (stages): Remove test, since it had no jobs.  Add
	upload and release.
	(build-distcheck:script): Configure with --enable-maintainer-mode, to
	ensure that flex-generated scanners are fresh.

	* Makefile.am (gen_start_date): Remove superfluous quotes.

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.
	(bootstrap:before_script): Add wget, needed to fetch Gnulib PO files.
	(build-distcheck:before_script): Add git, needed by gitlog-to-changelog.
	(build-distcheck:artifacts): Add bootstrapped/*.tar.xz.

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

	Switch CI image to debian:unstable

	This gives us newer versions of various dependencies such as the

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

	Pacify gcc -fanalyzer in manconv

	* src/manconv_main.c (main): Assert that from_code is non-NULL; this is

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

	Fix crash in globbing if run with no arguments

	* src/globbing_test.c (parse_opt): Emit a usage message if there are no

	* NEWS: Document this.

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

	Pacify gcc -fanalyzer in catman

	It isn't actually possible for sections to be NULL after argp parsing
	has finished, but "gcc -fanalyzer" can't easily determine that, and it's
	easy enough to arrange for it not to matter.

	* src/catman.c (main): Handle case where sections is NULL.

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

	Pacify gcc -fanalyzer in some database functions

	In GCC 11.2.0, -fanalyzer seems to get confused by copies by assignment
	of "struct datum", and thinks that there are use-after-free or
	double-free possibilities with multiple loop iterations.  These seem to
	be false positives, so ignore them for now.

	* libdb/db_lookup.c (dblookup_pattern): Ignore false use-after-free
	diagnostic.
	* src/accessdb.c (main): Ignore false double-free diagnostics.
	* src/catman.c (parse_for_sec): Ignore false use-after-free diagnostics.
	* src/check_mandirs.c (sanity_check_db): Ignore false double-free
	diagnostics.
	(purge_pointers, purge_missing): Ignore false use-after-free
	diagnostics.
	* src/whatis.c (do_apropos): Ignore false use-after-free and double-free
	diagnostics.

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

	Pacify gcc -fanalyzer in dbdelete

	The refs list can't in fact be empty by this point (because we checked
	earlier that we could look up this_ref in it), but it's hard for "gcc
	-fanalyzer" to prove that, so help it understand that multi_content can
	never end up being NULL.

	* libdb/db_delete.c (dbdelete): Initialize multi_content before looping
	over refs.

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

	Assert that some xasprintf calls return non-NULL

	"gcc -fanalyzer" notices that xasprintf can return NULL in some
	situations (string length > INT_MAX, invalid format string, or multibyte
	conversion error), and that we weren't handling this in various cases
	where we use the return value in contexts that require non-NULL values.
	The situations seem obscure enough for simple asserts to be appropriate.

	* lib/pathsearch.c (pathsearch): Assert that xasprintf returns non-NULL.
	* lib/tempfile.c (create_tempdir): Likewise.
	* lib/util.c (remove_directory): Likewise.

	Fix path searching crash if getcwd fails

	xgetcwd can return NULL if getcwd returns NULL for reasons other than
	ENOMEM, so we should handle this.  Found by "gcc -fanalyzer".

	* lib/pathsearch.c (pathsearch, directory_on_path): Emit a fatal error
	if xgetcwd returns NULL.
	* po/POTFILES.in: Add lib/pathsearch.c.
	* NEWS: Document this.

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

	Update to Gnulib 20211231

	In line with Gnulib, we now require Autoconf 2.64.

	* bootstrap: Sync to Gnulib 14db2b71b5bd05b94ec6126617fd32cd5f1016cd.
	* bootstrap.conf (GNULIB_REVISION): Set to

	(buildreq): Bump required autoconf version to 2.64.
	* configure.ac (AC_PREREQ): Bump to 2.64.
	(--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.
	* include/manconfig.h.in (create_tempdir, appendstr): Move NODISCARD to
	the start of these function declarations, required by draft C2x.
	* patches/argp-domain.patch: Rebase.
	* NEWS: Document this.

	"ANSI_X3.4-1968" if locale_charset returned NULL or the empty string.

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

	Trim down direct Gnulib dependencies a little

	* bootstrap.conf (gnulib_modules): Add c99 (already used indirectly, but
	seems like a good idea to request directly now).  Remove getopt-gnu,
	lock, and unsetenv, none of which we use directly.  Replace fcntl with
	fcntl-h and signal with signal-h, since we use the corresponding header
	files directly but not the corresponding functions.
	* .gitignore: Remove lib/getopt.h.

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

	Fix warnings with Autoconf >= 2.70

	Use Gnulib attribute.h properly

	manconfig.h previously used _GL_ATTRIBUTE_FORMAT_PRINTF_SYSTEM without

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

	Simplify interface to container iterator macros

	The Gnulib container iterator macros (GL_LIST_FOREACH_* and
	GL_MAP_FOREACH_*) have to run code both before and after a chunk of
	user-supplied code.  This previously required a START/END macro pair
	used something like this:

	    GL_LIST_FOREACH_START (names, name) {
	        ...
	    } GL_LIST_FOREACH_END (names);

	This doesn't look natural in C, and so it was easy to get it wrong.

	It's possible to do better, at the cost of some tricky macros.
	Fortunately, Simon Tatham has already done the hard work in
	https://www.chiark.greenend.org.uk/~sgtatham/mp/, and the necessary
	header file is MIT-licensed, so we can incorporate it.  Now these
	iterator macros are used more like this, which is a much more natural C
	style:

	    GL_LIST_FOREACH (names, name) {
	        ...
	    }

	* lib/mp.h: New file.
	* lib/Makefile.am (libman_la_SOURCES): Add mp.h.
	* lib/README: Add mp.h.  Rephrase introductory text about licensing to
	account for an MIT-licensed file.

	Rewrite as ...
	(GL_LIST_FOREACH): ... this.  Update all callers.
	(GL_MAP_FOREACH_START, GL_MAP_FOREACH_END): Rewrite as ...

	(appendstr): Use _GL_ATTRIBUTE_SENTINEL rather than ATTRIBUTE_SENTINEL.

	Allow clock_gettime64; return ENOSYS so libcs can engage fallbacks

	libcs such as musl expect ENOSYS to be returned (not EPERM) in their
	fallback code, so change the seccomp filter to be more agreeable to
	them.

	At the same time, clock_gettime is permitted in the filter, so permit
	clock_gettime64 as well -- it will be needed by 2038 in any case.

	* lib/sandbox.c (make_seccomp_filter): Set default action to
	SCMP_ACT_ERRNO (ENOSYS).  Allow clock_gettime64.

	Remove "Type" column from DB table in mandb(8)

	The database types table in mandb(8) has always been a bit
	dubiously-placed; it's really more about how man-db is configured, and
	as such makes more sense in manual/db.me (which indeed has an extended
	version of the same table).  It causes particular problems in translated
	versions of this page, where it's very easy for it to become too wide
	and cause "make check" failures.

	A proper fix for this would probably require updating existing
	translations, but an easy improvement is to remove the "Type" column: it
	has negligible relevance here, and removing it makes it much easier for
	translated versions to stay within page width limits.

	* man/man8/mandb.man8 (DATABASE CACHES): Remove "Type" column from
	table.

2020-07-02  Colin Watson  <cjwatson@debian.org>

	Avoid po4a confusion with \c

	po4a >= 0.58 (I think) changes its handling of \c slightly, resulting in
	incorrect output for the admittedly awkward uses of \c in man(1).
	Rearrange markup to avoid this.

	* man/man1/man.man1 (OVERVIEW): Recast description of the syntax of
	locale environment variables using \f[BIR] rather than .B/.RI and \c.
	(Controlling formatted output): Coalesce markup for the default prompt
	into a single .BI macro, avoiding the need for \c.  Unfuzzy most
	translations.
	* NEWS: Document this.

2020-06-22  Colin Watson  <cjwatson@debian.org>

	Fix po4a version comparison

	po4a's versions don't quite conform to Perl's standard versioning
	arrangements, producing very confusing results when trying to compare
	two-component and three-component versions (because "0.47" is equivalent
	to "v0.470.0").  Perhaps we should use some other version comparison
	system instead, but in the meantime patch things up so that what we
	currently use behaves more sensibly.

	* man/po4a/Locale/Po4a/Manext.pm (_parse_version): New subroutine.
	(shiftline, pushline, translate): Use _parse_version, and always use a
	leading "v" on the right-hand side.

2020-05-31  Colin Watson  <cjwatson@debian.org>

	Make gxditview work with seccomp sandbox

	"man -X" and friends used to work by running groff with -X, causing it
	to run gxditview itself.  This didn't work with the seccomp sandbox: the
	sorts of system calls that a text processor needs to make are not very
	much related to the sorts of system calls that an X client needs to
	make.

	Instead, run groff with -X -Z to pass the appropriate options to troff
	but stop it from running gxditview, and then run gxditview ourselves
	without sandboxing.  This also lets us set a better window title.

	* src/man.c (make_roff_command): In gxditview mode, run groff with -Z as
	well as -X.
	(make_display_command): In gxditview mode, add an appropriate gxditview
	process.

	logic, without saving a cat page.

	Release man-db 2.9.0-pre1

2019-09-30  Colin Watson  <cjwatson@debian.org>

	Add a new man-recode program

	This has an interface designed for bulk conversion, and so can be much
	faster than running "man --recode" on each page.

	lexgrog, zsoelim: Suppress more compiler warnings

	-Wsuggest-attribute=malloc was added in GCC 8, so don't try to ignore it

	Suggested by Tanguy Ortolo and Paul Wise.  Fixes Debian bug #677350.

	* src/man.c (split_page_name): Accept "page(section)" form as well as
	"page.section".
	* src/tests/man-suffixed-extension: Test the "page(section)" form.
	* man/man1/man.man1 (SYNOPSIS): Don't mention the "page.section" form
	here; it gets too unwieldy to try to express all the possibilities in a
	synopsis.
	(EXAMPLES): Document "page(section)" form.
	(OPTIONS): Hyphenate "Non-argument options" thus.
	* NEWS: Document this.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Make some debugging output less verbose

	Also indent some sections of debugging output, which allows removing
	some blank lines.

	Fixes Debian bug #863920.

	* src/catman.c (main): Remove unnecessary debugging output of manp
	before calling create_pathlist.
	* src/manp.c (main): Likewise.
	* src/mandb.c (main): Likewise.

	* src/man.c (main): Remove debugging output of ruid and euid, which was
	redundant with init_security.  Remove extra newline before "using %s as
	pager".
	* src/manp.c (describe_flag, print_list): Remove: everything that adds
	items to this list already emits a more human-friendly debugging
	message.  Remove caller of print_list.
	(add_sections): Squash debugging output onto one line, and indent it by
	two spaces.
	(add_def, add_manpath_map, add_mandb_map, add_mandatory): Indent
	debugging output by two spaces.
	(read_config_file): Remove extra newline after "From the config file
	%s:".
	(get_manpath_from_path): Remove extra newlines before "path directory
	%s" and "adding mandatory man directories".
	(add_expanded_dir_to_list): Remove noisy "%s is already in the manpath"
	debugging output.  Indent "adding %s to manpath" by two spaces.
	(add_man_subdirs): Remove noisy "and doesn't have ../man, man,
	../share/man, or share/man subdirectories" debugging output.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Refactor deduplication in create_pathlist

	This is more efficient, and also has the useful side-effect of reducing
	noise in debug output.

	* src/manp.c (struct canonicalized_path): New structure.
	(canonicalized_path_new, canonicalized_path_equals,
	canonicalized_path_hash, canonicalized_path_free): New functions.
	(add_dir_to_path_list): Canonicalize the given path and (if it exists)
	add both the original and canonicalized versions as a pair.
	(create_pathlist): Simplify: rather than doing a second quadratic-time
	pass to eliminate duplicates, we now avoid inserting them in linear time
	as we go along.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	man(1): Explain interactions between -w/-W and -a

	Reported by Bjarni Ingi Gislason.  Fixes Debian bug #803712.

	* man/man1/man.man1 (Main modes of operation): Explain that the -w and
	-W options only print a single match by default, but that -a can be used
	to print all matches.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Suggest "man man" if run with no arguments

	Fixes Debian bug #869798.

	* src/man.c (gripe_no_name): Suggest running "man man".
	* NEWS: Document this.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	* NEWS: Document recent manual page improvements.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Mention where other manual pages come from

	* man/man1/man.man1 (OVERVIEW): Explain that individual manual pages
	normally come with whatever they document.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Revamp man(1) to be a more accessible introduction

	Fixes Savannah bug #53050.

	* man/man1/man.man1 (SYNOPSIS): Delete details of most options, as it
	had got much too long and indigestible.  The OPTIONS section below
	remains, and is better-organised and easier to read.  Delete the "man
	-c" form entirely, as it's only for internal use by catman.
	(DESCRIPTION): Move list of default sections to ...
	(DEFAULTS): ... here.
	(EXAMPLES): Use a real example rather than the peculiar "alias"
	terminology for "man -t".
	(OVERVIEW): Various minor editorial improvements.  Remove discussion of
	index database caches: it's mostly irrelevant to users, and is already
	better-documented in mandb(8), apropos(1), and whatis(1).  Simplify
	discussion of where pages are stored.  Briefly describe what cat pages
	are.  Rewrite description of localisation support to read more fluently
	and to take into account that most users will already have a suitable
	locale set up.  Drop discussion of translations of this package's own
	messages: this should be standard rather than something that we
	explicitly need to call out here, and the term "message catalogues" was
	opaque.
	(DEFAULTS): Remove discussion of index database caches, as above.
	Remove discussion of cat pages, since this is an implementation detail
	and confused matters here too much.
	(Finding manual pages): Tighten up language in description of
	--sections.  Simplify description of --update, and tell readers that it
	is normally better to run mandb(8) instead.
	(FILES): Remove mention of index database caches from here.  While
	man(1) does use them, they're an implementation detail and are
	better-documented elsewhere.
	(SEE ALSO): Remove overly-detailed cross-references to setlocale(3),
	ascii(7), latin1(7), the man-db manual, and the FSSTND.  Add a paragraph
	mentioning documentation in other formats, such as info(1) or HTML.
	* man/man5/manpath.man5 (FORMAT): Remove stray quote before the FSSTND
	keyword.
	* man/man8/mandb.man8 (DESCRIPTION): Remove claim that index database
	caches are usually maintained by man(1).

	* man/man1/man.man1, man/man1/manpath.man1: Use the "..." style of
	quoting rather than the `...' style.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Improve documentation of MANROFFOPT

	Reported by Bjarni Ingi Gislason.  Fixes Debian bug #914938.

	* man/man1/man.man1 (ENVIRONMENT): Rephrase description of MANROFFOPT to
	make it clear that it is added to the formatter's command line, rather
	than to man's command line.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Remove confusing use of "on-line"

	Nowadays "on-line" tends to be understood as "on the internet" rather
	than "on a screen", so avoid the term.

	Reported by Dan Jacobson.  Fixes Debian bug #774402.

	* docs/man-db.lsm: Say "system help files" rather than "on-line help
	files".
	* man/man1/man.man1 (NAME): Say "system reference manuals" rather than
	"on-line reference manuals".
	* manual/intro.me (Introduction): Say "information" rather than "online
	information".
	* manual/man_db.me: Say "manual page system" rather than "online manual
	page system".

	* man/man1/lexgrog.man1 (EXAMPLES): Update examples quoting man(1)'s
	description.
	* manual/db.me (Example database): Likewise.
	* manual/intro.me (Introduction): Likewise.
	* src/tests/man-mandatory-manpath: Update test quoting man(1)'s
	description.

	(OPTIONS): Change .BR to .B if there is only one argument.
	(FILES): Add a space around "|" to increase readability.
	(AUTHOR): Protect "." with "\&" if it is followed by a space and does
	not mean the end of a sentence.

2019-09-08  Colin Watson  <cjwatson@debian.org>

	Apply italic corrections

	Partly based on suggestions from Bjarni Ingi Gislason in Debian
	bug #892421, although I had to take a slightly different approach to
	avoid confusing po4a.

	* man/man1/apropos.man1 (OPTIONS): Apply italic corrections to
	descriptions of --sections and --systems.  Simplify three-font handling
	for --systems.
	* man/man1/man.man1 (Finding manual pages): Likewise.
	* man/man1/whatis.man1 (OPTIONS): Likewise.

	man(1): Minor typographic changes

	Fixes Debian bug #892230.

	* man/man1/man.man1 (DESCRIPTION, HISTORY): Protect "." with "\&" if it
	is followed by a space and does not mean the end of a sentence.
	(EXAMPLES): Use a macro to change to the italic font instead of \fI if
	possible.  The macros have the italic corrections.
	(EXAMPLES, Controlling formatted output, Getting help, SEE ALSO): Change
	.BR/.IR to .B/.I if there is only one argument, or else separate the
	second argument from the first if needed.
	(DEFAULTS): Begin each sentence on a new line.
	(FILES): Add a space around "|" to increase readability.

	%sections% on its own line.

2019-09-07  Colin Watson  <cjwatson@debian.org>

	Escape %troff% expansion correctly in manual pages

	Fixes part of Debian bug #892230.

	* configure.ac: Substitute troff_as_troff_input, which is the same as
	troff but with suitable escaping so that "groff -mandoc" turns into
	"groff \-mandoc".
	* man/replace.sin.in (%troff%): Substitute @troff_as_troff_input@ rather
	than @troff@.

	Order results manually for NDBM as well as GDBM

	Commit 3a753221a3dddaf4870a86a4dca4771ed2cd80b3 in 2003 (!) worked
	around the fact that GDBM's firstkey/nextkey interface doesn't return
	ordered results.  However, at least when using GDBM's NDBM compatibility
	interface, this may be true for NDBM too.  Extend the manual result
	ordering code to cover both of these backends.

	* libdb/db_gdbm.c (parent_keys, datum_compare, datum_equals, datum_hash,
	datum_free, empty_datum, man_gdbm_firstkey, man_gdbm_nextkey,

2019-08-23  Colin Watson  <cjwatson@debian.org>

	Pass database file name in function parameters

	Storing it in a global variable with an unresolved symbol from libmandb
	was never very clean, and caused linking complications on some
	platforms.

	Fixes Savannah bug #56734.

	* libdb/mydbm.h (database): Remove external symbol.
	* src/accessdb.c: Remove obsolete comment.
	* src/catman.c (database): Remove global variable.

	* NEWS: Document this.

2019-08-23  Colin Watson  <cjwatson@debian.org>

	Use MYDBM_FILE->name for error messages

	We previously used the global "database" variable, but we were either
	also passing a MYDBM_FILE around already or could easily do so, and it's
	cleaner to get the file name from there now that it's consistently
	available on all backends.

	* libdb/db_lookup.c (gripe_corrupt_data): Add dbf parameter.  Get file
	name from dbf->name rather than from the global database variable.
	Update all callers.
	(gripe_replace_key, split_data, split_content): Add dbf parameter.
	Update all callers.
	(dblookup_pattern): Get file name from dbf->name rather than from the

	* src/whatis.c (do_apropos): Likewise.

2019-08-23  Colin Watson  <cjwatson@debian.org>

	Store database file name alongside its handle

	The GDBM backend already did things this way, but it's convenient to do
	it the same way for all backends.

	Rename libmandb's various backend-specific functions to be uniformly
	man_<backend>_<operation>.  In the cases of btree and ndbm there was
	already no clash with the libraries they depend on, but this makes them
	match the gdbm backend.

	* libdb/db_btree.c (btree_close): Rename to ...
	(man_btree_close): ... this.
	(btree_flopen): Rename to ...
	(man_btree_open): ... this.  Wrap the returned file handle in a

	(btree_set_time): Rename to ...
	(man_btree_set_time): ... this.
	Update all prototypes and callers for all renames.
	(man_btree_close, man_btree_replace, man_btree_insert, man_btree_fetch,
	man_btree_exists, man_btree_findkey, man_btree_firstkey,
	man_btree_nextkey, man_btree_nextkeydata, man_btree_get_time,
	man_btree_set_time): Take man_btree_wrapper parameter rather than DB *.
	Update all callers.

	* libdb/db_ndbm.c (ndbm_flclose): Rename to ...
	(man_ndbm_close): ... this.
	(ndbm_flopen): Rename to ...
	(man_ndbm_open): ... this.  Copy the given file name before passing it
	to dbm_open, since at least GDBM's compatibility implementation declares
	that parameter as non-const.  Wrap the returned file handle in a
	man_ndbm_wrapper structure that remembers the file name.
	(ndbm_get_time): Rename to ...
	(man_ndbm_get_time): ... this.
	(ndbm_set_time): Rename to ...
	(man_ndbm_set_time): ... this.

	(MYDBM_FILE) [NDBM]: Change to man_ndbm_wrapper.
	(man_btree_wrapper): New structure.
	(MYDBM_FILE) [BTREE]: Change to man_btree_wrapper.

	* libdb/db_lookup.c (gripe_lock): Constify filename parameter.
	* libdb/db_storage.h (gripe_lock): Update prototype.

	sandbox: Reorganise using @system-service set

	systemd defines a @system-service set now which covers some of the ones
	that were previously isolated here, so reorganise to take account of
	that.  No functional change.

	* lib/sandbox.c (make_seccomp_filter): Reorganise using systemd's new
	@system-service set.

2019-08-21  Colin Watson  <cjwatson@debian.org>

	sandbox: Set default action to EPERM, not TRAP

	Returning EPERM rather than raising SIGSYS is no less secure, and it's
	more likely that code injected via LD_PRELOAD will be able to recover
	from this somehow.

	* lib/sandbox.c (make_seccomp_filter): Set default action to
	SCMP_ACT_ERRNO (EPERM), not SCMP_ACT_TRAP.

2019-08-14  Colin Watson  <cjwatson@debian.org>

	Improve manual build portability slightly

	* manual/Makefile.am ($(MANUAL).pp, .pp.dvi, .pp.ps, .pp.tdvi,
	.tdvi.tps, .pp.cat, .pp.html): Use "mv -f" rather than just "mv", since
	Automake seems to prefer that for its own rules.

2019-05-02  Colin Watson  <cjwatson@debian.org>

	Make manual build more robust against failures

	Fixes Savannah bug #56254.

	* manual/Makefile.am ($(MANUAL).pp, .pp.dvi, .pp.ps, .pp.tdvi,

	Simplify case-insensitivity in word_fnmatch

	Using FNM_CASEFOLD saves us from having to lower-case the pattern
	manually, and it also fixes the behaviour of "apropos -w" when given a
	non-lower-case pattern.

	* lib/wordfnmatch.c (word_fnmatch): Use isalpha and FNM_CASEFOLD rather
	than manually lower-casing string or expecting pattern to have already
	been lower-cased.
	* NEWS: Document this.

2019-02-05  Colin Watson  <cjwatson@debian.org>

	Simplify case-insensitive comparisons in whatis

	We can just use strcasecmp and similar functions rather than
	lower-casing comparands manually.

	In some corner cases this may result in matches that would not
	previously have been returned (e.g. "whatis -w" with a non-lower-case
	pattern).

	* src/whatis.c (parse_name): Use strcasecmp and FNM_CASEFOLD rather than
	manually lower-casing dbname or expecting pages to have already been

	whatis or expecting page to have already been lower-cased.
	(parse_whatis): Remove lowpages parameter; pass pages directly to match

	need it.

	Use bool type where appropriate

	sandbox: Work around Microsoft SCEP

	This is a proprietary antivirus program and I've only been able to guess
	at how to handle it.  Note that it is no longer supported by Microsoft

	Automake conditional (true unless --with-systemdsystemunitdir=no).

	Fix incorrect error message

	Reported by Julian Gilbey.  Fixes Debian bug #913721.

	* src/man.c (check_standard_fds): Correct error message if stdout is not
	open for writing (not "for reading", as previously claimed).

2018-11-09  Colin Watson  <cjwatson@debian.org>

	release.sh: Simplify Lex handling

	release.sh had a hack to ensure that flex-generated scanners are fresh
	in release tarballs.  This is more easily achieved by configuring with
	--enable-maintainer-mode, which causes Automake to enable the Lex
	rebuild rule.

	* release.sh: Configure with --enable-maintainer-mode; drop conditional
	removals of src/lexgrog.c and src/zsoelim.c.

2018-11-09  Colin Watson  <cjwatson@debian.org>

	lexgrog: Fix handling of \- in RHS of NAME section

	Fixes Debian bug #913351.

	* src/lexgrog.l (MAN_NAME): Split into MAN_NAME (left-hand side) and
	MAN_DESC (right-hand side).  Most rules remain as before, except that \-
	and similar are only handled specially in MAN_NAME and transition to
	MAN_DESC, and rules that add a 0x11 marker (indicating the start of a
	new whatis definition) transition to MAN_NAME.
	(MAN_NAME_AT, MAN_NAME_BSX, MAN_NAME_BX, MAN_NAME_BX_RELEASE,
	MAN_NAME_DQ, MAN_NAME_FX, MAN_NAME_NX, MAN_NAME_OX): Rename to
	MAN_DESC_*.
	(mdoc_text): Transition to MAN_DESC rather than MAN_NAME.
	(newline_found): If adding 0x11, transition to MAN_NAME.
	* src/tests/lexgrog-3: New file.
	* src/tests/Makefile.am (ALL_TESTS): Add lexgrog-3.
	* NEWS: Document this.

	No functional change.

	* src/lexgrog.l: Make more use of start condition scopes.  Reindent
	rules somewhat to make better use of vertical space.

2018-11-03  Nikola Forró  <nforro@redhat.com>

	Fix several resource and memory leaks

	* lib/decompress.c (decompress_zlib): Fix fd leak if gzdopen fails.

	man-arg-config-file: fix to use config_file

	* m4/man-arg-config-file.m4: Compute config_file_basename based on
	config_file, not withval.

2018-08-20  Colin Watson  <cjwatson@debian.org>

	Fail to configure if flex is needed but missing

	Fixes Savannah bug #54541.

	* configure.ac: Issue an error if AC_PROG_LEX didn't find a lexer
	generator and either src/lexgrog.c or src/zsoelim.c is missing (as may
	be the case when building from a git clone rather than a released
	tarball).

2018-08-02  Colin Watson  <cjwatson@debian.org>

	Fix warning from gcc -Wcast-function-type

	This exposed the fact that errors from unlink in the cleanup path were
	previously ignored.  We now issue a warning in the same way that
	commit_tmp_cat does.

	* src/man.c (cleanup_unlink): New function.
	(open_cat_stream, close_cat_stream, display_catman): Use cleanup_unlink
	rather than an incorrect cast of unlink.

	* Version: 2.8.4.

2018-07-27  Colin Watson  <cjwatson@debian.org>

	Work around Gnulib/gettext mismatch

	The versions of gettext infrastructure files installed by gnulib-tool
	don't necessarily match our configured AM_GNU_GETTEXT_VERSION, so we
	need to fix things up in bootstrap.

	* bootstrap.conf (gnulib_tool_option_extras): Set --po-base to gl/ref-po
	rather than gnulib/po.
	(bootstrap_post_import_hook): Merge temporary gl/ref-po directory into
	gl/po.

2018-07-27  Colin Watson  <cjwatson@debian.org>

	Upgrade to Gnulib 20180726

	then allow msgset (second argument 0) and msgsnd.
	* NEWS: Document this.

2018-07-15  Colin Watson  <cjwatson@debian.org>

	sandbox: Allow some shared memory operations

	These were previously only allowed when ESET File Security is in use,
	but the Astrill VPN seems to require something similar, there are
	doubtless other such preload hacks, and they're relatively harmless.

	* lib/sandbox.c (make_seccomp_filter): Allow shmat (third argument
	SHM_RDONLY), shmctl (second argument IPC_STAT), shmdt, and shmget
	regardless of preloads.
	* NEWS: Document this.

2018-06-08  Colin Watson  <cjwatson@debian.org>

	Check for external formatter in correct directory

	Check for mandb_nfmt and mandb_tfmt in the manual page hierarchy as
	documented, not in the current directory.  This was broken by the
	working-directory-handling changes in 2.8.3.

	Reported by Josh Triplett.  Fixes Debian bug #901007.

	* src/man.c (NFMT_PROG, TFMT_PROG): Remove leading "./".
	(make_roff_command): Refactor confusing #ifdef forest.  Prefix dir to
	TFMT_PROG/NFMT_PROG rather than looking in the current directory.  Don't
	look for an external formatter at all if dir is NULL.
	* NEWS: Document this.

2018-06-08  Colin Watson  <cjwatson@debian.org>

	Define an access(2) wrapper with clearer semantics

	As usual for system calls, access(2) returns zero on success.  However,
	I generally think of it as "can we access this file in this way", where
	boolean semantics would be more convenient, and find it too easy to
	invert logic by accident when using the system call directly.  Define a
	CAN_ACCESS wrapper with boolean semantics.

	* include/manconfig.h.in (CAN_ACCESS): New macro.
	* lib/tempfile.c (path_search): Use CAN_ACCESS.
	* src/catman.c (check_access): Likewise.

	that's no longer necessarily done up-front.
	* src/whatis.c (main): Run program_name through base_name before

	(gnulib_tool_option_extras): Remove --no-cache-modules (accidental
	leftover from earlier testing).
	(local_gl_dir): Set to 'gnulib-local' to avoid confusion with 'gl' as

	(buildreq): Bump minimum autopoint and gettext versions to 0.18.3,

2018-04-05  Colin Watson  <cjwatson@debian.org>

	Suppress spurious gettext headers in --help output

	Some of man-db's commands have post-options help text but no pre-options
	help text.  Unfortunately, the way this works in argp (separating the
	two sections using a '\v' character) means that this results in argp
	trying to translate the empty string, which produces gettext catalog
	headers.  The easiest way to suppress this odd behaviour seems to be to
	use a help filter function, so do that.

	Reported by Rafael Fontenelle.

	* src/accessdb.c (help_filter): Return NULL for ARGP_KEY_HELP_PRE_DOC.
	* src/lexgrog_text.c (help_filter): New function.
	(argp): Add help_filter.

	sandbox: Allow kill and tgkill outright

	This is unfortunate but unavoidable: groff uses kill to explicitly pass
	on SIGPIPE to its child processes, and we can't do any more
	sophisticated filtering in seccomp.

	Based on a patch by Paul Wise.  Fixes Debian bug #892309.

	* lib/sandbox.c (make_seccomp_filter): Allow kill and tgkill

	sandbox: Generalise libesets_pac.so check slightly

	* lib/sandbox.c (make_seccomp_filter): LD_PRELOAD or /etc/ld.so.preload
	can just contain "libesets_pac.so" without an explicit path, so make the
	search slightly more permissive.

2018-02-20  Colin Watson  <cjwatson@debian.org>

	sandbox: Handle /etc/ld.so.preload

	At least ESET File Security may be configured using /etc/ld.so.preload
	rather than the LD_PRELOAD environment variable, so unfortunately we
	need to check that too.

	* lib/sandbox.c (search_ld_preload): New function, handling both
	LD_PRELOAD and /etc/ld.so.preload.
	(can_load_seccomp, make_seccomp_filter): Use search_ld_preload.

2018-02-19  Colin Watson  <cjwatson@debian.org>

	sandbox: Work around ESET File Security

	This is a proprietary antivirus program, so this is only a best guess
	from strace output.  The choices are to disable the sandbox entirely or
	to allow a few socket-related system calls if this antivirus program is
	detected, and the latter is probably slightly better.

	Reported by John Sivak.

	* lib/sandbox.c (make_seccomp_filter): If LD_PRELOAD contains the
	substring "/libesets_pac.so", then allow some socket-related system
	calls so that the preload wrapper can talk to its daemon.

2018-02-07  Colin Watson  <cjwatson@debian.org>

	Refactor do_system_drop_privs

	Now that we have pipecmd_pre_exec, this can be simplified quite a bit.

	Refactor sandbox attachment to be more composable

	The sandbox interface now exposes the necessary load/free primitives,

	Add fallback pager if the compile-time default is not executable

	A problem with man-db's man is that in the case of the user giving no
	configuration via conf files, argv, or environment variables; man
	defaults to less as pager (PAGER); but less may not be present on the
	system. Sure, other pagers may be selected in aforementioned ways, but
	then the defaults are overridden, making that unsuitable for
	install-time configuration.

	This patch makes man check (if that becomes relevant) if PAGER is
	executable, further defaulting to cat (which is basically ubiquitous,
	being in original Unix, POSIX, and GNU Coreutils) if it is not. Thus
	the poor beginner Unix users without less installed will be able to
	get man pages.

	* src/man.c (sh_lang_first_word): New function.

	Fix locale macro loading for Chinese

	The intent was always that we should load the macro file corresponding

	src/tests: Use /tmp for temporary directories

	Reduces disk reads/writes made by 'make check -C src'.

	Fall back to ./tmp-* if 'mktemp -d' fails.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Eliminate dangerous setgid-root directories

	man-db has created its cache directories as setgid root for nearly 20
	years.  This seems to have originated in https://bugs.debian.org/26002.
	However, this has some dangerous consequences, such as:

	  http://www.halfdog.net/Security/2015/SetgidDirectoryPrivilegeEscalation/

	It seems best to arrange for cache files and directories to be man:man
	rather than man:root.  To do this reliably, as well as adjusting various
	chown and chmod calls, we make man and mandb be setgid man as well as
	setuid man (except in the --disable-setuid case).  This is a much
	simpler and safer solution to the original problem, and doesn't
	introduce any interesting new privilege since the man group's only real
	purpose is to be the man user's primary group and nothing in cache
	directories is group-writeable.

	* configure.ac (AC_CHECK_FUNCS): Add lchown.
	* lib/security.c (init_security): Record initial real and effective
	group IDs as well as user IDs.
	(drop_effective_privs, regain_effective_privs): Update gid.
	* lib/xchown.c (xlchown) [HAVE_LCHOWN]: New function.
	* lib/xchown.c (xlchown) [HAVE_LCHOWN]: Add prototype.
	* m4/man-arg-setuid.m4: Set man_mode to 6755 rather than 4755 in the
	--enable-setuid case.
	* src/Makefile.am (install-exec-hook): Check for man_mode being 6755
	rather than 4755.  Set the group of man and mandb as well as their
	owner.
	* src/check_mandirs.c (chown_if_possible): New function.  This is
	somewhat more careful than previous implementations, changes the group
	as well as the user if possible, and prefers lchown if it is available.
	(mkcatdirs): Drop S_ISGID from cat directories.  Use chown_if_possible.
	(fix_permissions, fix_permissions_tree): New functions to remove setgid
	bit from existing cat directories.
	(testmandirs): Call fix_permissions_tree.
	* src/check_mandirs.h (chown_if_possible): Add prototype.
	* src/man.c (commit_tmp_cat): Set cat file group as well as owner.
	* src/mandb.c (check_chown): Remove.
	(do_chown): Stop taking a uid parameter.  Use chown_if_possible.
	(mandb): Use chown_if_possible for CACHEDIR.TAG.  Set ownership and
	permissions of CACHEDIR.TAG even if it already exists.
	(process_manpath): Set ownership of database files even if they have not
	been changed.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Make --disable-cache-owner imply --disable-setuid

	* m4/man-arg-setuid.m4: Set man_mode="755" if --disable-cache-owner was
	given and neither --enable-setuid nor --disable-setuid was given.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Update manual for cache-owner/setuid changes

	* manual/intro.me (Arguments to configure): Add --enable-cache-owner and
	--disable-cache-owner.  Remove --enable-setuid[=ARG].  Adjust
	description of --disable-setuid.
	* manual/misc.me (Modes of operation): Add --disable-cache-owner to the
	non-setuid modes.  Mention --enable-setuid rather than
	--enable-setuid=USER.
	* README (Non-generic arguments to configure): Update.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Allocate dbpaths on the heap rather than the stack

	process_manpath's stack may have gone out of scope by the time cleanup
	functions are called.

	* src/mandb.c (cleanup): Free dbpaths.
	(process_manpath): Allocate dbpaths on the heap.

2016-12-10  Colin Watson  <cjwatson@debian.org>

	Handle cleanup stack more safely

	If push_cleanup was called unexpectedly between a
	push_cleanup/pop_cleanup pair, then the pop_cleanup would remove the
	wrong cleanup function and chaos could ensue.  Avoid this by being more
	precise about which cleanup function should be popped.

	* lib/cleanup.c (pop_cleanup): Take "fun" and "arg" arguments.  Pop the
	topmost matching function from the stack, rather than just the topmost
	function.  Update all callers and prototypes.

2016-12-09  Colin Watson  <cjwatson@debian.org>

	Separate cache owner from --enable-setuid option

	It's useful to have a notion of the cache owner even when man is not
	installed setuid.  --enable-setuid no longer takes an argument, and the
	owner is now set by the --enable-cache-owner option instead.

	* m4/man-arg-cache-owner.m4: New file.
	* m4/man-arg-setuid.m4: Stop accepting an argument.  Only set man_mode,
	not man_owner.
	* configure.ac: Call MAN_ARG_CACHE_OWNER.
	* src/Makefile.am (install-exec-hook): Only chown man and mandb if
	man_mode is 4755 (as well as the existing test for man_owner being
	non-empty).

2016-11-21  Colin Watson  <cjwatson@debian.org>

	Rename some anomalous x* functions

	The usual (though not universal) pattern in gnulib is for xfoo to mean
	"foo or exit".  Rename x* to check_* so that they don't conflict with
	this.

	Fix use-after-free in ult_src

	Reported by Hanno Boeck.  Fixes Savannah bug #45854.

	* src/ult_src.c (ult_src): Take a copy of base when recursing rather
	than passing it directly as the new name argument, since it may be
	freed by the recursive call.
	* NEWS: Document this.

2015-09-09  Colin Watson  <cjwatson@debian.org>

	Remove unnecessary check before free

	* src/ult_src.c (ult_src): Don't check whether base is non-NULL
	before freeing it.

2015-08-30  Rafael Kitover  <rkitover@gmail.com>

	Squeeze blank lines internally instead of pager -s

	Add a pipecmd in make_display_command to combine multiple blank lines in
	the output into one, which is what e.g. less -s does.

	Stop automatically appending -s to pager command in configure.

	Fixes Debian bug #796584.

	* configure.ac: Stop automatically appending -s to pager command.
	* src/man.c (squeeze_blank_lines): New function.

2015-04-08  Colin Watson  <cjwatson@debian.org>

	Allow using GDBM's NDBM compatibility layer

	This isn't very useful in practice since anyone using this could just
	use GDBM directly instead, but it's helpful for testing.

	* configure.ac: Check for gdbm-ndbm.h and libgdbm_compat.

2015-04-08  Colin Watson  <cjwatson@debian.org>

	man: Avoid dubious use of freopen to reopen base streams

	freopen doesn't actually work properly when base streams have been
	closed (at least with glibc), and it seems better to simply refuse to
	operate in such a non-conforming environment.

	* src/man.c (check_standard_fds): New function.
	(main): Call it rather than using freopen.

2014-11-16  Colin Watson  <cjwatson@debian.org>

	Allow building from git without gnulib-tool

	Since we don't want to keep Gnulib translations in revision control,
	we need gnulib-tool on $PATH when generating the build system in
	order to fetch them, but it's unnecessarily awkward to require
	everyone to have this just in order to build man-db from git.  Allow
	building without this, although it is still required for "make
	dist".

	* configure.ac: No longer issue an error if gnulib/po/Makefile.in.in
	is missing.  Instead, set the Automake conditional HAVE_GNULIB_PO to
	true if and only if gnulib/po/POTFILES.in exists, and only create
	gnulib/po/Makefile.in if gnulib/po/Makefile.in.in exists.
	* Makefile.am (SUBDIRS): Only include gnulib/po if HAVE_GNULIB_PO is
	true.

2014-11-14  Colin Watson  <cjwatson@debian.org>

	this where applicable.
	(run): Call libtool using an absolute path.

2014-09-18  Colin Watson  <cjwatson@debian.org>

	Move zsoelim to pkglibexecdir

	This avoids clashes with other packages; for example, Slackware's groff
	package installs zsoelim as a symlink to soelim.

2014-09-17  Colin Watson  <cjwatson@debian.org>

	Don't store canonicalised versions of manpath elements

	We still compare canonicalised versions, but don't store them.
	Storing them results in looking up the wrong catpath in the case
	where one of the configured MANDB_MAP entries is a symlink.

	Broken by commit 01e5a4febfc7b6cd53991455315ae7744c8f31dd; fixes
	Fedora bug #1043401.

	* src/manp.c (create_pathlist): Compare canonicalised versions of
	manpath elements, but don't store them.
	* NEWS: Document this.

2014-09-16  Colin Watson  <cjwatson@debian.org>

	Don't use pointed-to name as title for database-located pages

	For a pointer record, the pointed-from name is a legitimate alias
	for the located page, and is likely to be closer to the name that
	the user requested.

	Fixes Debian bug #709405.

	* src/man.c (display_database): Don't use the pointed-to name to
	construct the title for display.

2014-09-16  Colin Watson  <cjwatson@debian.org>

2014-09-16  Colin Watson  <cjwatson@debian.org>

	Order files by first physical extent before reading

	Inspired by a similar change in dpkg.  This takes 'mandb -c' from
	104 to 32 seconds in a test installation, and 'man -K' from 74 to 38
	seconds.  On non-Linux systems where FIEMAP is not available, use
	posix_fadvise instead to preload files.

	* gnulib: Import nonblocking and openat modules.
	* configure.ac: Check for <linux/fiemap.h> and posix_fadvise.

	associated global declarations.

2014-09-15  Colin Watson  <cjwatson@debian.org>

	Reorder functions in man to remove need for header file

	man.h was only needed because of some poor function ordering in man.c.
	Reorder functions so that definition comes before use, except in one
	case of mutual recursion.

	* src/man.c (main): Move to end of file.
	(local_man_loop): Move to immediately before man.
	(man): Add a prototype declaration just before local_man_loop, to

	Use high-precision timestamps for manual pages

	* lib/util.c (is_changed): Compare high-precision timestamps.
	* libdb/db_storage.h (FIELDS): Increment to 10.

2014-09-10  Colin Watson  <cjwatson@debian.org>

	Move database mtime out of the database into file metadata

	This makes the database reproducible between installations, as long
	as the underlying database has predictable behaviour and the set of
	installed manual pages (including their timestamps) remains
	identical.  As a bonus, we now use high-precision times in several
	places.

	Fixes Debian bug #760895.

	* gnulib: Import futimens and timespec modules.
	* libdb/db_btree.c (btree_get_time, btree_set_time): New functions.
	* libdb/db_gdbm.c (man_gdbm_get_time, man_gdbm_set_time): New
	functions.
	* libdb/db_ndbm.c (ndbm_get_time, ndbm_set_time): New functions.
	* libdb/mydbm.h (man_gdbm_get_time, man_gdbm_set_time,
	ndbm_get_time, ndbm_set_time, btree_get_time, btree_set_time): Add
	prototypes.
	(MYDBM_GET_TIME, MYDBM_SET_TIME): New macros.
	* src/check_mandirs.c (testmandirs, create_db, count_glob_matches,
	purge_normal, purge_whatis, purge_missing): Use high-precision
	times.
	(update_db_time): Set file modification times rather than updating a
	database row.
	(create_db, purge_missing): Get database file modification times
	rather than fetching a database row.
	(purge_missing): If the new will_run_mandb argument is true, reset
	the database mtime to its value before purging; this ensures that
	mandb will still run as expected afterwards.
	* src/check_mandirs.h (purge_missing): Update prototype.
	* src/mandb.c (xcopy): Copy access and modification times.
	(process_manpath): Work out in advance of purging whether we will
	need to run mandb, and pass that to purge_missing.
	* include/manconfig.h.in (VER_ID): Bump to 2.5.0.
	(KEY): Remove.

	* man/man8/accessdb.man8 (DESCRIPTION), man/it/man8/accessdb.man8
	(DESCRIZIONE): Remove sample output, as it is of limited usefulness
	compared to how awkward it is to maintain, especially in text
	intended for translation.
	* man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update.
	* manual/db.me (Contents of an index database): Remove mention of
	$mtime$.
	(Example database): Remove $mtime$.  Update $version.

	* NEWS: Document this.  Bump version to 2.7.0 to correspond to the
	database version change.

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Make update_db_time static

	* src/check_mandirs.c (update_db_time): Make this static; its only
	uses are within the same file.
	* src/check_mandirs.h (update_db_time): Remove prototype.

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Remove unused reset_db_mtime function

	* src/check_mandirs.c (reset_db_mtime): Remove.  This function has
	been unused since man-db 2.4.2.
	* src/check_mandirs.h (reset_db_mtime): Remove prototype.
	* src/man.c: Stop including "check_mandirs.h".

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Don't purge entries from databases that fail sanity checks

	* src/check_mandirs.c (purge_missing): Return early if
	sanity_check_db fails, for instance in the case of a version
	mismatch.

2014-09-09  Colin Watson  <cjwatson@debian.org>

	Switch away from obsolescent utime function

	POSIX.1-2008 marks utime as obsolescent.  Switch to variants of the
	futimens/utimensat family instead, via Gnulib.  Use higher-precision
	times for cat pages.

	* gnulib: Import stat-time and utimens modules.
	* src/man.c (man_modtime): Change type to struct timespec.
