        mandb: Check for stray cats even if the manpath is unchanged

        * src/mandb.c (mandb): Require the database file to be open before
        calling `straycats`, but don't require `create_db` or
        `update_db_wrapper` to have made any changes to it.

        mandb: Fix crash when processing stray cats

        Regression introduced in man-db 2.11.0.  Fixes Debian bug #1027487.

        * src/straycats.c (check_for_stray): Pass a basic trace list to
        `store_descriptions`, since that's required as of commit

        Pacify gcc -Wanalyzer-use-of-uninitialized-value

        It incorrectly thought that `outleft` could be uninitialized in some
        cases.  Restructure code slightly to simplify its analysis.

        * src/manconv.c (try_iconv): Initialize `outptr` in all branches of the
        conditional beginning with `if (handle_iconv_errors)`.

2022-12-31  Colin Watson  <cjwatson@debian.org>

        Fix segfault when nroff is not installed

        * src/man.c (try_section): Only free the `names` list if it is non-NULL
        due to `NROFF_MISSING` being defined, and return early if options are
        set such that cat files cannot be used either.
        * NEWS.md: Document this.

2022-11-05  Colin Watson  <cjwatson@debian.org>

        Replace $ in page names rather than trying to escape it

        Jakub Wilk points out in Debian bug #1021951 that attempting to use the

        dollar signs with question marks instead.

        * include/manconfig.h (LESS_OPTS): Revert addition of `--use-backslash`.
        * src/man.c: Replace `$` characters with `?` rather than trying to

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.

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

        Recognize more Hungarian translations of the NAME section

        as "\('E" or "\('e".
        * NEWS.md: Document this.

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

        Sort whatis references below real pages more aggressively

        I think this makes more sense in most cases, and it definitely fixes
        some observed odd behaviour.

        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>

        Silence error for empty mandir with missing catdir

        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`

        * src/man.c (escape_less): Also escape `$` characters.
        * 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

        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.

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

        Bump next version to 2.11.0

        There are quite a few substantial changes here that I think justify an

        * libdb/db_xdbm.c (man_xdbm_firstkey): Cast `gl_list_free` to
        `gl_mapvalue_dispose_fn`, not `gl_listelement_dispose_fn`.  (These were
        in practice identical but are semantically distinct.)

        Reformat option declarations using macros

        The previous tabular presentation had some advantages, but it only
        looked reasonable in wide terminals, was often quite cumbersome to
        maintain, and played poorly with `clang-format`.

        * include/manconfig.h (OPT, OPT_FULL, OPT_ALIAS, OPT_HIDDEN,
        OPT_GROUP_HEADER, OPT_HELP_COMPAT): New macros.

        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`).

        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.

        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`.

        Reduce indentation in store_descriptions a bit

        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.

        * 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.

        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 ...

        Remove infoalloc macro

        It doesn't really pull its weight.

        * libdb/db_lookup.c (dblookup, dblookup_pattern): Call `XZALLOC (struct
        mandata)` rather than `infoalloc ()`.

        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.

        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.

        Drop LSM file

        The LSM format is a very old format for software, and it is dead for
        many years already. Since keeping the .lsm up-to-date is basically not
        much of use, simply drop it altogether.

        Cache filters alongside whatis information

        `mandb` needs to cache filters together with whatis information, as
        otherwise pages were incorrectly recorded with no filters if `mandb`
        happened to use cached whatis information for them rather than reading
        it from scratch.

        * src/check_mandirs.c (struct whatis): Add filters.

        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.

        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.

        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.

        mkcatdirs: Skip nonexistent man directories

        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.

        Apply various minor shell syntax improvements

        `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>

        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.
        (create_pathlist): Add OVERRIDE_DIR at the canonicalization stage

        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.

        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

        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`
        so that the compiler can straightforwardly know what's going on.

        * bootstrap.conf (gnulib_modules): Add verror.

        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.

        man: Make dbdelete_wrapper use the correct database

        Even if it has permissions to delete stale entries from the database,
        dbdelete_wrapper can't assume that the most recently opened database is

        database to which the candidate in question belongs.

        Optimize manconv_inprocess for UTF-8 target encoding

        If the target encoding is UTF-8, then manconv's first stage (trial
        conversion from UTF-8) can more efficiently be replaced with UTF-8
        validation, leaving the original decompressed buffer unchanged on

        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
        seconds.

        Thanks to Steinar H. Gunderson for a proof of concept, which I reworked
        extensively.

        Add a layer of abstraction to decompression

        It would be useful to have an optimized version of the common case of
        zlib decompression that doesn't involve forking subprocesses.  As
        preparation for this, insert an abstraction layer around code that reads
        from decompressors.  This abstraction layer looks almost identical to
        the `libpipeline` API except for name changes, but having it allows us
        to implement decompression in some other way.

        Code that requires `libpipeline`-based decompression can use
        `decompress_get_pipeline` to assert that the decompressor uses
        `libpipeline` and return the underlying `pipeline *`.

        Remove AM_MAINTAINER_MODE

        I enabled this in fb4afb0b75, saying that timestamps were too fragile
        for the rebuild rules to work well.  However, I've changed my mind: git
        is good at making sure that file modification times are updated when
        checking out a different commit, and tarballs include timestamp
        information.  Moreover, with `AM_MAINTAINER_MODE` and without passing
        `--enable-maintainer-mode`, flex output isn't automatically regenerated,
        which is impossibly annoying and has tripped me up countless times since

        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.

        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.

        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.

        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

        "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.

        fcntl-h and signal with signal-h, since we use the corresponding header
        files directly but not the corresponding functions.

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.

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

        Gnulib-provided macros.

        ATTRIBUTE_WARN_UNUSED_RESULT.

        libcs such as musl expect ENOSYS to be returned (not EPERM) in their

        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.

        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.

        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.

        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

        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.

        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.

        Fixes Debian bug #933576.

        * bootstrap.conf (gnulib_modules): Add renameat, tempname, and unlinkat.

        * src/tests/man-suffixed-extension: Test the "page(section)" form.
        * man/man1/man.man1 (SYNOPSIS): Don't mention the "page.section" form

        synopsis.

        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.

        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.

        -W options only print a single match by default, but that -a can be used
        to print all matches.

        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

        (FILES): Add a space around "|" to increase readability.
        (AUTHOR): Protect "." with "\&" if it is followed by a space and does

        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

        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

        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

        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

        Returning EPERM rather than raising SIGSYS is no less secure, and it's

        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.

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.
        (match): Use strcasestr and isalpha rather than manually lower-casing
        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.

        Now that we're using <stdbool.h> anyway due to gl_list (with Gnulib

        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

        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_*.
        (mdoc_text): Transition to MAN_DESC rather than MAN_NAME.
        (newline_found): If adding 0x11, transition to MAN_NAME.

        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

        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

        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

        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.

        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.

        Use Gnulib progname module

        This lets us produce more accurate error messages when programs are

        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.

        This is a proprietary antivirus program, so this is only a best guess

        to allow a few socket-related system calls if this antivirus program is

        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):

        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.

        Fix locale macro loading for Chinese

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

        See: https://savannah.gnu.org/bugs/?44941

        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

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

        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.

        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.

        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.

        Rename some anomalous x* functions

        The usual (though not universal) pattern in gnulib is for xfoo to mean

        Build text manual with LC_ALL=C

        fine.

        * manual/Makefile.am (.pp.cat): Set LC_ALL=C.

2015-11-05  Colin Watson  <cjwatson@debian.org>

        ditroff is set.
        (make_roff_command): Try add_roff_line_length regardless of troff.
        The line length is passed to the macro package, not to the output
        device, although get_roff_line_length will still sometimes not use
        it (e.g. if using the "ps" device).  Fixes Debian bug #801241.
        * NEWS: Document 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.

        Try to get terminal width from /dev/tty

        If man is running within something like lesspipe, then there may be
        a current tty that neither stdin nor stdout points to.  Try to get
        hold of it using /dev/tty.  Fixes Fedora bug #1255930.

        * lib/linelength.c (get_line_length): Try /dev/tty before either
        stdout or stdin.

        * man/man1/man.man1 (EXAMPLES): "man -k" and "man -f" are equivalent to
        "apropos" and "whatis" respectively, not "apropos -r" and "whatis -r".

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>

        Clean up freeing of datum structures

        * libdb/mydbm.h (MYDBM_FREE): Remove.

        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

        Move zsoelim to pkglibexecdir

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

        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.

        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.

        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.

        Fixes Debian bug #574410.

        * gnulib: Import nonblocking and openat modules.

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

        Make various functions static

        These functions are only used within the same compilation unit, so
        have no need for external linkage.

        * src/check_mandirs.c (sanity_check_db): Make static.
        * src/mandb.c (is_lang_dir, tried_catdirs_free, purge_catdir,

        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

        Remove old and broken FAST_BTREE code

        This was marked as experimental and broken when I took over man-db
        13 years ago, and I've hardly touched it.  There's no point in
        keeping it around.

        * include/manconfig.h.in (FAST_BTREE): Remove commented definition.
        * libdb/db_btree.c (test_insert, gripe_get, dbstore, dblookup):

        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.

        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.

        (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
        $mtime$.

        * 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
