Release man-db 2.9.3

2020-06-22  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.

Clarify description of zstd in configure

Suggested by crabbed halo ablution in Savannah bug #57558.

	utility".

	* NEWS: Document this.

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

Fix configure logic for enabling COMP_CAT

Only enable COMP_CAT if a compressor is defined.  (We don't have all
	possible decompression utilities set up to be compressors too.)

* configure.ac: Only enable COMP_CAT if $compressor is non-empty.

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.
	(display): In gxditview mode, call the ordinary "display formatted page"
	logic, without saving a cat page.

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

Fix document font size for -X75-12 and -X100-12

Reported by Konrad Schwarz.

	argument to -X contains "-12".

Fix language/territory candidate comparison logic

When I extracted the COMPARE_LOCALE_ELEMENTS macro, I apparently left in
	an explicit reference to territory that should have been the "elt"
	parameter.  As a result, some cases of language and territory comparison
	went wrong, in particular resulting in pt_BR users seeing pt pages ahead
	of pt_BR pages.

Reported by Rafael Fontenelle.

Add a new man-recode program

This has an interface designed for bulk conversion, and so can be much

	message.  Remove caller of print_list.
	(add_sections): Squash debugging output onto one line, and indent it by

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.

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.

	make it clear that it is added to the formatter's command line, rather
	than to man's command line.

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.

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.

Pass database file name in function parameters

Storing it in a global variable with an unresolved symbol from libmandb

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.

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_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

Don't save cat pages if --nh/--nj is used

Fixes Savannah bug #55731.

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

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.

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,

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

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
	lower-cased.

	whatis or expecting page to have already been lower-cased.
	(parse_whatis): Remove lowpages parameter; pass pages directly to match
	instead.
	(do_apropos): Remove lowpages; parse_name and parse_whatis no longer
	need it.

Use Gnulib's lchown function

Also remove lib/xchown.*; with only one call site, they don't pull their
	weight over equivalent inline code.

* bootstrap.conf (gnulib_modules): Add lchown.
	* configure.ac (AC_CHECK_FUNCS): Remove check for lchown.
	* lib/Makefile.am (libman_la_SOURCES): Remove xchown.c and xchown.h.

2019-01-26  Colin Watson  <cjwatson@debian.org>

Use bool type where appropriate

Now that we're using <stdbool.h> anyway due to gl_list (with Gnulib
	providing <stdbool.h> if necessary), it makes sense to use it for our
	own functions that have essentially boolean semantics.

Automatically add more man directories to manpath

Will Starms reported that, if both ../man and ../share/man directories
	(for example) exist relative to a directory on $PATH, then only the
	first was considered.

	rather than returning them, and continue even if some have been found.

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
	and so users should probably replace it with something else, but I still
	want to minimise the number of support requests I get related to it.

* lib/sandbox.c (make_seccomp_filter): If libscep_pac.so is preloaded,
	then allow some system calls related to sockets and System V message
	queues.
	* NEWS: Document this.

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.

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_*.

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).

Fix warning from gcc -Wcast-function-type

This exposed the fact that errors from unlink in the cleanup path were

	(open_cat_stream, close_cat_stream, display_catman): Use cleanup_unlink

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

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.

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.

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.
	* src/whatis.c (help_filter): New function.
	(apropos_argp): Add help_filter.
	* NEWS: Document this.

* lib/sandbox.c (make_seccomp_filter, _sandbox_load): Declare as static.

2018-03-17  Colin Watson  <cjwatson@debian.org>

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
	unconditionally.
	(adjust_seccomp_filter): Remove.
	(_sandbox_load): Remove call to adjust_seccomp_filter.

sandbox: Handle qemu-user returning EFAULT

Fixes Debian bug #891109.

* lib/sandbox.c (_sandbox_load): Interpret EFAULT from seccomp_load as
	meaning that seccomp is unavailable, since this can be returned by some
	versions of qemu-user.
	* NEWS: Document this.

2018-02-28  Colin Watson  <cjwatson@debian.org>

sandbox: Add some more ESET affordances

* lib/sandbox.c (make_seccomp_filter): If libesets_pac.so is preloaded,
	then allow some shared memory calls and checking for the existence of
	other processes.

2018-02-25  Colin Watson  <cjwatson@debian.org>

sandbox: Work around snoopy

Fixes Debian bug #890861.

* lib/sandbox.c (search_ld_preload): Cache /etc/ld.so.preload contents
	between calls.
	(make_seccomp_filter): Allow some socket-related system calls if
	libsnoopy.so is preloaded.

2018-02-25  Colin Watson  <cjwatson@debian.org>

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.
	* NEWS: Document this.

sandbox: Allow kill/tgkill for current process

xz is multithreaded, so the threading library may need to use tgkill to

	* src/man.c (make_browser): Add drop_privs pre-exec hook to browser

	privileges.

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.
	(main): Skip configured pager if it is not executable.
	* man/man1/man.man1 (Controlling formatted output, ENVIRONMENT):
	Document fallback to cat.

Fix preprocessor handling after insertions

If man has added prefixes to a page to handle such things as disabling
	hyphenation, then it also needs to take account of that when looking for
	a preprocessor line at the start of the page.

Reported by Bjarni Ingi Gislason.  Fixes Debian bug #867857.

* src/man.c (get_preprocessors_from_file): Skip over as many blocks
	ending with an .lf macro as there are prefixes.
	(get_preprocessors): Pass the number of prefixes through to
	get_preprocessors_from_file.
	(make_roff_command): Take pp_string as an argument rather than
	dbfilters; callers should now call get_preprocessors themselves.
	(display): Rename seq_ncmds to prefixes.  Call get_preprocessors before
	calling make_roff_command.

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.

Make --disable-cache-owner imply --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.

Allocate dbpaths on the heap rather than the stack

process_manpath's stack may have gone out of scope by the time cleanup

* 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.

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).

	ditroff is set.
	(make_roff_command): Try add_roff_line_length regardless of troff.

Fix use-after-free in ult_src

Reported by Hanno Boeck.  Fixes Savannah bug #45854.

Allow using GDBM's NDBM compatibility layer

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.

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.

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

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

	seconds.  On non-Linux systems where FIEMAP is not available, use
	posix_fadvise instead to preload files.

Fixes Debian bug #574410.

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.

	* src/tests/Makefile.am (TESTS_ENVIRONMENT): Export STAT_HAS_NSEC to
	tests.
	* src/tests/testlib.sh (next_second): Do nothing if STAT_HAS_NSEC is
	"yes".

2014-09-11  Colin Watson  <cjwatson@debian.org>

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.

	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>

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

Remove unused reset_db_mtime function

	* 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.

Switch away from obsolescent utime function
