2023-09-23 Colin Watson Release man-db 2.12.0 2023-09-19 Colin Watson systemd: Avoid duplicate cleanup of old cat pages Thanks to Ferenc Wágner. Fixes https://bugs.debian.org/1052221. * init/systemd/man-db.service.in: Remove call to `find`; this is already handled equivalently by `init/systemd/man-db.conf.in`, and having both can result in error messages due to the two cleanups running concurrently. * NEWS.md: Document this. 2023-08-20 Colin Watson bootstrap: Make --skip-po disable Gnulib downloads too Fixes https://bugs.debian.org/1050089. * bootstrap.conf: If the `--skip-po` option is explicitly passed, then don't pass `--po-base` or `--po-domain` options to `gnulib-tool`, and don't merge `gl/ref-po/` into `gl/po/`. 2023-08-07 Colin Watson README.md: Update my copyright notice 2023-08-07 Colin Watson Update URLs for libpipeline and flex * NEWS.md, docs/INSTALL.quick: Update libpipeline URLs to . * docs/INSTALL.quick: Update flex URL to . 2023-08-07 Colin Watson Update to Gnulib stable-202307 as of 20230728 * bootstrap.conf (GNULIB_REVISION): Set to d1b40e09c9c04d5c1ff120373397c6180bc16beb. 2023-08-07 Colin Watson Update syscall lists from systemd ab9617a766 * lib/sandbox.c (make_seccomp_filter): Add `futex_waitv`, `riscv_hwprobe`, and `arm_fadvise64_64`. 2023-08-07 Petr Pisar Update Czech translation * po/cs.po: Update from Translation Project. 2023-08-07 Mario Blättermann Update German manual page translation * man/po4a/po/de.po: Update from Translation Project. 2023-08-07 Boyuan Yang <073plan@gmail.com> Update Simplified Chinese manual page translation * man/po4a/po/zh_CN.po: Update from Translation Project. 2023-08-07 Boyuan Yang <073plan@gmail.com> Update Simplified Chinese translation * po/zh_CN.po: Update from Translation Project. 2023-08-07 Remus-Gabriel Chelu Update Romanian manual page translation * man/po4a/po/ro.po: Update from Translation Project. 2023-08-07 Seong-ho Cho Update Korean manual page translation * man/po4a/po/ko.po: Update from Translation Project. 2023-08-07 Seong-ho Cho Update Korean translation * po/ko.po: Update from Translation Project. 2023-08-06 Colin Watson Release man-db 2.12.0-pre2 2023-08-06 Colin Watson Update translation files * man/po4a/po/*.pot, man/po4a/po/*.po, po/*.pot, po/*.po: Update. 2023-08-06 Remus-Gabriel Chelu Update Romanian manual page translation * man/po4a/po/ro.po: Update from Translation Project. 2023-08-06 Colin Watson man(1): Document handling of file names without -l more accurately Fixes https://gitlab.com/man-db/man-db/-/issues/18. * man/man1/man.man1: Without `-l`, we only fall back to interpreting arguments as local file names if they contain a slash. Explain this more accurately. * NEWS.md: Document this. 2023-08-06 Colin Watson Merge branch 'cjwatson/man-negative-warnings' into 'main' man: Allow disabling warnings enabled by default in groff See merge request man-db/man-db!8 2023-08-06 Colin Watson man: Allow disabling warnings enabled by default in groff 2023-08-06 Colin Watson man(1): Fix typography in STANDARDS Reported by Mario Blättermann. * man/man/man.man1 (STANDARDS): Use `\-`, not a mix of Unicode hyphens and unescaped ASCII hyphens. * man/po4a/po/*.pot, man/po4a/po/*.po: Update. 2023-08-06 Remus-Gabriel Chelu Update Romanian translation * po/ro.po: Update from Translation Project. 2023-08-06 Mario Blättermann Update German manual page translation * man/po4a/po/de.po: Update from Translation Project. 2023-08-06 Mario Blättermann Update German translation * po/de.po: Update from Translation Project. 2023-08-06 Yi-Jyun Pan Update Traditional Chinese translation * po/zh_TW.po: Update from Translation Project. 2023-08-06 Colin Watson Declare variable as const * lib/util.c (init_locale): Declare `locale` as const. 2023-08-06 Colin Watson Merge branch 'guess_manpath_fix' into 'main' Fixed add_man_subdirs to correctly add PATH elements with trailing paths See merge request man-db/man-db!10 2023-08-06 Jan Seeger Fixed add_man_subdirs to correctly add PATH elements with trailing paths 2023-08-06 Colin Watson Release man-db 2.12.0-pre1 * man/po4a/po/*.pot, man/po4a/po/*.po, po/man-db.pot, po/*.po: Update. * NEWS.md: Bump next version to 2.12.0. * configure.ac: Update version and date. 2023-08-06 Colin Watson Always pass a line length to nroff Fixes https://bugs.debian.org/1041704. * src/man.c (get_roff_line_length): Remove `line_length != 80` condition. * NEWS.md: Document this. 2023-08-01 Colin Watson Merge branch 'branden-lexgrog-thinko' into 'main' lexgrog.1: Fix thinko in my recent contribution See merge request man-db/man-db!9 2023-07-28 G. Branden Robinson lexgrog.1: Fix thinko in my recent contribution In commit bbf7701c4f, 19 July, I got the sense of the tests that governed the macro definitions backwards. I fooled myself because I use a more complex test in groff's an-ext.tmac file (written in a non-intuitive way due to AT&T troff limitations) so that it's easy to run groff's automated tests on them. 2023-07-22 Colin Watson Ensure that time_t can go past 2038 * bootstrap.conf (gnulib_modules): Add `year2038-recommended`. * NEWS.md: Document this. 2023-07-22 Colin Watson man: Pass --regex/--wildcard on to whatis/apropos Fixes https://gitlab.com/man-db/man-db/-/issues/13. * src/man.c (do_extern): Pass `-r` or `-w` options to the external program if necessary. * man/man1/man.man1 (Main modes of operation): Document that `-f` and `-k` are still only approximately equivalent to `whatis` and `apropos` respectively (since `man` accepts slightly different options). * NEWS.md: Document this. 2023-07-22 Colin Watson Update pre-commit hooks * .pre-commit-config.yaml (shellcheck-py): Update to v0.9.0.5. 2023-07-22 Colin Watson Upgrade to Gnulib stable-202307 * bootstrap: Sync to Gnulib b7f7ed06961454cdf77b93c6c00c3e3f26202663. * bootstrap.conf (GNULIB_REVISION): Set to b7f7ed06961454cdf77b93c6c00c3e3f26202663. * src/tests/Makefile.am (fspause_LDADD): Link with `$(NANOSLEEP_LIB)` instead of `$(LIB_NANOSLEEP)`. * NEWS.md: Document this. 2023-07-21 Colin Watson Include .lf corrections in debugging output The pipeline command names in `PIPELINE_DEBUG` output are deliberately abbreviated in the cases where the command is inserting data into the `*roff` input stream, in an attempt to convey the essential parts without overwhelming the reader. However, it probably does make sense to include `.lf` corrections there, since if you're relying on the debugging output to construct a manual shell pipeline when debugging an issue with a page, you'll want the `.lf` corrections so that line numbers still come out correctly. * src/man.c (add_roff_line_length, display): Include `echo .lf 1` in command names where appropriate. 2023-07-20 Colin Watson Take advantage of groff's AD string and HY register Fixes https://gitlab.com/man-db/man-db/-/issues/23. Thanks to G. Branden Robinson for assistance. * src/man.c (make_roff_command) [TROFF_IS_GROFF]: Implement `--no-hyphenation` using `-rHY=0`. This requires groff >= 1.19, released in 2003. (disable_hyphenation): Only define if `TROFF_IS_GROFF` is not defined. (display): Only use the more complex hyphenation-control mechanism if `TROFF_IS_GROFF` is not defined. * src/man.c (disable_justification): Implement using `.ds AD l` if groff is at least version 1.23.0. (display): Adjust debugging output to reflect this (more or less). * NEWS.md: Document this. 2023-07-20 Colin Watson Document false negatives from "man -K" Fixes https://gitlab.com/man-db/man-db/-/issues/14. * man/man1/man.man1 (Main modes of operation): Document false negatives due to things like `\-`. * NEWS.md: Document this. 2023-07-20 Colin Watson man(1): Add a STANDARDS section Fixes https://gitlab.com/man-db/man-db/-/issues/20. * man/man1/man.man1 (STANDARDS): New section. * NEWS.md: Document this. 2023-07-19 Colin Watson Change "CONFORMING TO" to "STANDARDS" This is in line with `man-pages(7)`. See https://gitlab.com/man-db/man-db/-/issues/20. * man/man1/man.man1 (DESCRIPTION): Recommend `STANDARDS` rather than `CONFORMING TO`. * NEWS.md: Document this. 2023-07-19 Colin Watson Fix test failures when a working iconv is not available Part of https://gitlab.com/man-db/man-db/-/issues/25. * configure.ac: Substitute `HAVE_ICONV`. * src/tests/Makefile.am (TESTS_ENVIRONMENT): Export `HAVE_ICONV`. * src/tests/testlib.sh (report_skip): New function to skip an individual test out of several in a file. (skip): Refactor slightly to call `report_skip`. * src/tests/man-recode-in-place, src/tests/man-recode-suffix, src/tests/manconv-coding-tags, src/tests/manconv-guess-from-encoding, src/tests/manconv-incomplete-char-at-eof, src/tests/manconv-odd-combinations: Skip several tests if `HAVE_ICONV` is not `yes`. * NEWS.md: Document this. 2023-07-19 Colin Watson NEWS.md: Document some recent commits 2023-07-19 Colin Watson Update warning regex for groff 1.23.0 Part of https://gitlab.com/man-db/man-db/-/issues/25. * man/check-man: groff 1.23.0 says "cannot break line" rather than "can't break line"; update regular expression. 2023-07-19 Colin Watson Avoid translation fallout from lexgrog(1) fix * man/man1/lexgrog.man1: Protect `.ds mC CW` with `.if !'po4a'hide'`, to avoid "CW" showing up as a string for translation. 2023-07-19 G. Branden Robinson Improve lexgrog(1) portability This fixes a test failure in man1/lexgrog.1 when building against groff 1.23.0. Borrow code from groff 1.23.0's "an-ext.tmac" file (licensed as permissively as a decadent society) to implement `EX` and `EE` extension macros from Ninth Edition Research Unix (1986) (and groff) to get monospaced code displays in a more portable way. There is no way to portably change font families in pure man(7) itself, and the names of troff typefaces aren't very portable either. There is also no portable way to test for the _existence_ of a font. FTW. ("Portable" here largely means "to AT&T device-independent troff implementations", for which there has been no official source since the mid-1990s.[1] Several AT&T Unix System V licensees/descendants have continued to ship their own vendored versions, but these have enjoyed little or no development for the past 3 decades.) * Define a string `mC` to store the name of a presumed monospaced roman typeface. Use "CW", which is portable to AT&T device-independent troff of the early 1980s before it occurred to anyone that Courier might someday be available in italic and bold styles (and budget available to purchase them). * Define `mC` as "CR" if using a typesetting device and the formatter is groff, or claims groff compatibility by the setting the `.g` register. This is reasonably portable to modern implementations given traditional troff font naming practices and the pervasive influence of Adobe Software and the "base fonts" of its PostScript and PDF specifications. * If not typesetting (i.e., if using nroff), define `mC` as "R", which is certain to be available. * Define `EX` and `EE` macros as groff does, if the formatter does not set the `.g` register. * Migrate from `ft CW` and `nf` requests to `EX` macro calls. * Migrate from `ft P` and `fi` requests to `EE` macro calls. * Replace an inline use of `\f(CW` with a change to inline bold. There is to date no portable way to inline a font family change. Test passes now. Tested as-is and with the `EX` and `EE` macro definitions forcibly enabled.

Reorganize positions of some other syscalls according to their positions in systemd's sets. * NEWS.md: Document this. 2023-01-08 Colin Watson Release man-db 2.11.2 2023-01-01 Colin Watson 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. * src/tests/mandb-whatis-broken-link-changes: Update expected output. * NEWS.md: Document this. 2023-01-01 Colin Watson 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 d3e4b5522ae8152f10db0bb98e6873c9cc17ed59. * NEWS.md: Document this. 2022-12-31 Colin Watson 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 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. 2022-12-31 Colin Watson Fix compile and test failures when troff is not groff Fixes https://gitlab.com/man-db/man-db/-/issues/12. * src/man.c (ONLY_TROFF_IS_GROFF): Only define if `HAS_TROFF` is defined.

Noticed by `gcc -Og`. * src/zsoelim.l (zsoelim_open_file): Initialize `decomp` to NULL. 2022-10-18 Colin Watson Recognize more Hungarian translations of the NAME section * src/lexgrog.l (hu_name): Handle the case where "É" or "é" is written as "\('E" or "\('e". * NEWS.md: Document this. 2022-10-18 Colin Watson 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 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 Add 3type to default section list This is used by the Linux man-pages package, and should be lower priority than section 2. Suggested by Alejandro Colomar. Fixes https://gitlab.com/cjwatson/man-db/-/issues/5. * include/manconfig.h (STD_SECTIONS): Add `3type` between sections `2` and `5`. * m4/man-arg-sections.m4 (MAN_ARG_SECTIONS): Likewise. * man/man5/manpath.man5 (FORMAT): Update documentation of SECTION. * src/tests/man-exact-section-matches: Update default section order. * src/man_db.conf.in (SECTION): Update documentation. * NEWS.md: Document this. 2022-10-17 Colin Watson Escape $ in page names when constructing less prompts Fixes Debian bug #1021951. * include/manconfig.h (LESS_OPTS): Add `--use-backslash`. * src/man.c (escape_less): Also escape `$` characters. * NEWS.md: Document this. 2022-10-15 Colin Watson Release man-db 2.11.0 2022-10-13 Colin Watson 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 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 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 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 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 Convert many more ints to bools I don't expect this to make a significant runtime difference, but it makes some things easier to analyse visually. * lib/cleanup.c (do_cleanups_sigsafe): Change `in_sighandler` parameter type to bool. Update all callers. (push_cleanup): Change `handler_installed` local variable type to bool. * lib/cleanup.h (do_cleanups_sigsafe): Update prototype. * lib/compression.c (comp_info): Change `want_stem` parameter type to bool.

(display_database): Remove setting of `found_a_stray`. 2022-10-07 Colin Watson Add some more pure function attributes * lib/encodings.c (compatible_encodings): Mark as pure. * src/man.c (is_section): Likewise. * src/manp.c (get_config, get_def, get_def_user, is_global_mandir): Likewise. 2022-10-07 Colin Watson Default to --disable-cache-owner on systems without getuid * m4/man-arg-cache-owner.m4 (MAN_ARG_CACHE_OWNER): If the system doesn't have `getuid`, force cache files to have unconstrained cache ownership, and issue a warning if `--enable-cache-owner` was given. 2022-10-07 Colin Watson Fix installation on systems with non-empty EXEEXT * src/Makefile.am (install-exec-hook): Add `$(EXEEXT)` to `chown`/`chmod` calls. * NEWS.md: Document MinGW portability work. 2022-10-07 Colin Watson Fix build on systems without SIGPIPE * bootstrap.conf (gnulib_modules): Add sigpipe. * src/mandb.c (main): Drop `#ifdef SIGPIPE` guards, as Gnulib now ensures that it's defined. 2022-10-07 Colin Watson Fix build on systems without getuid * lib/tempfile.c (running_setid): New function; always returns false if the system doesn't have `getuid`, since in that case we won't have been able to drop privileges either. 2022-10-07 Colin Watson Fix build on systems without * lib/security.h: Only include `` if `MAN_OWNER` is defined. 2022-10-07 Colin Watson Fix build on systems without * bootstrap.conf (gnulib_modules): Add termios. * src/man.c (get_term): Replace with a no-op stub if the system has no `` (Gnulib tests for it and can replace some functions, but its replacement isn't sufficient here). 2022-10-07 Colin Watson Fix build on systems without SIGHUP * lib/cleanup.c (trap_abnormal_exits, untrap_abnormal_exits): Guard uses of `SIGHUP` with an `#ifdef`. 2022-10-06 Colin Watson 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. * NEWS.md: Document this. 2022-10-06 Emir SARI Update Turkish translation * po/tr.po: Update from Translation Project. 2022-10-06 Emir SARI Update Turkish manual page translation * man/po4a/po/tr.po: Update from Translation Project. 2022-10-06 Boyuan Yang <073plan@gmail.com> Update Simplified Chinese manual page translation * man/po4a/po/zh_CN.po: Update from Translation Project. 2022-10-06 Remus-Gabriel Chelu Update Romanian manual page translation * man/po4a/po/ro.po: Update from Translation Project. 2022-10-06 Remus-Gabriel Chelu Update Romanian translation * po/ro.po: Update from Translation Project. 2022-10-03 Mario Blättermann Update German manual page translation * man/po4a/po/de.po: Update from Translation Project. 2022-10-02 Colin Watson Release man-db 2.11.0-pre1 2022-10-02 Colin Watson Bump next version to 2.11.0 There are quite a few substantial changes here that I think justify an updated minor number. * NEWS.md: Bump to 2.11.0. 2022-10-02 Colin Watson Update translation files * po/man-db.pot, po/*.po: Update. 2022-10-02 Colin Watson Fix harmless but incorrect cast * 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.) 2022-10-02 Colin Watson 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. * src/accessdb.c (options): Rewrite using `OPT*` macros. * src/catman.c (options): Likewise. * src/globbing_test.c (options): Likewise. * src/lexgrog_test.c (options): Likewise. * src/man-recode.c (options): Likewise. * src/man.c (options): Likewise. * src/manconv_main.c (options): Likewise. * src/mandb.c (options): Likewise. * src/manpath.c (options): Likewise. * src/whatis.c (options): Likewise. * src/zsoelim_main.c (options): Likewise. 2022-10-02 Colin Watson Add CI checks for Berkeley DB and NDBM * .gitlab-ci.yml (build-berkeley-db, build-ndbm): New jobs. 2022-10-02 Colin Watson 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. 2022-10-02 Colin Watson mandb: Rearrange database path operations Moving these into "methods" of `struct dbpaths` makes the control flow clearer by avoiding lots of inlined `#ifdef`s. I fixed a possible crash in `mandb -f` in the process, exposed by the clearer control flow. * src/mandb.c (dbpaths_init, dbpaths_copy_to_tmp, dbpaths_remove_tmp): New functions. (finish_up): Rename to ... (dbpaths_rename_from_tmp): ... this. (do_chown): Rename to ... (dbpaths_chown_if_possible): ... this. (cleanup_sigsafe): Rename to ... (dbpaths_unlink_tmp): ... this, and take a `struct dbpaths *` argument rather than `void *`. (cleanup): Rename to ... (dbpaths_free_elements): ... this, and take a `struct dbpaths *` argument rather than `void *`. (mandb, process_manpath): Use new `dbpaths_*` functions. Only call `dbpaths_rename_from_tmp` if `run_mandb` is set (in practice this was always true anyway but this makes it clearer). Only call `dbpaths_chown_if_possible` if `run_mandb` is set and `dbpaths_rename_from_tmp` was called (this may have caused a crash in some edge cases involving `mandb -f`). 2022-10-01 Colin Watson 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 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 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 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 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 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 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 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 store_descriptions: Improve debugging * src/descriptions_store.c (store_descriptions): Log the extension of each entry being stored. 2022-09-24 Colin Watson 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 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 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 Fix stored ID for links Database entries for links were often incorrectly stored as `ULT_MAN`, depending on the exact order in which pages were scanned. They are now stored more consistently as `SO_MAN`. * src/descriptions_store.c (store_descriptions): Override the ID from `ULT_MAN` to `SO_MAN` if the name is not the last entry in the trace. (Previously we overrode from `SO_MAN` to `ULT_MAN` if the name was the last entry in the trace, but not the converse.) * NEWS.md: Document this. 2022-09-24 Colin Watson 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 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 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 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 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 filename_info: Always allocate info->name Only one call site has any interest in this being unset (in order to pass the result to `dbstore`), and even there it's easier for the caller to deal with unsetting it. Otherwise, it's strictly more convenient if the structure returned by `filename_info` always includes the name of the page. * lib/filenames.c (filename_info): Remove `req_name` parameter; update all callers. Always set `info->name` before returning successfully. * lib/filenames.h (filename_info): Update prototype. * src/check_mandirs.c (test_manfile): Use `info->name` for `manpage_base` rather than poking around in `info->addr`. (count_glob_matches): Remove `name` parameter; update all callers. * src/descriptions_store.c (store_descriptions): Drop now-unnecessary check for `trace_info->name`. * src/man.c (do_global_apropos_section): Build `title` using `info->name` rather than poking around in `info->addr`. * src/mandb.c (update_one_file): Drop now-unnecessary check for `info->name`. 2022-09-23 Colin Watson Reduce indentation in store_descriptions a bit * src/descriptions_store.c (store_descriptions): Use an early-continue construction to save a level of indentation. 2022-09-23 Colin Watson Simplify the filename_info interface This interface is a bit less confusing. * libdb/db_lookup.c (free_mandata_elements, free_mandata_struct): Move to ... * lib/filenames.c (free_mandata_elements, free_mandata_struct): ... here. * libdb/db_storage.h (free_mandata_elements, free_mandata_struct): Move to ... * lib/filenames.h (free_mandata_elements, free_mandata_struct): ... here. * lib/filenames.c (filename_info): Return a `struct mandata` with the `addr` element set to the buffer containing the fields, rather than returning the buffer and taking a pointer to a `struct mandata` as a parameter. Update all callers. * lib/filenames.h (filename_info): Update prototype. 2022-09-23 Colin Watson Move manual page file name utilities to lib/ * src/filenames.c: Move to ... * lib/filenames.c: ... here. * src/filenames.h: Move to ... * lib/filenames.h: ... here. Update positioning of all includes. * lib/Makefile.am (libman_la_SOURCES): Add `filenames.c` and `filenames.h`. * src/Makefile.am (man_recode_LDADD): Link with `$(LIBMAN)` instead of `$(LIBMANDB)`. (lexgrog_SOURCES, man_SOURCES, mandb_SOURCES): Remove `filenames.c` and `filenames.h`. * po/POTFILES.in: Rename `src/filenames.c` to `lib/filenames.c`. * lib/filenames.c (gripe_bogus_manpage): Remove `quiet < 2` condition. (filename_info): Add `warn_if_bogus` parameter; only call `gripe_bogus_manpage` if it is set. Update all callers. * lib/filename.h (filename_info): Update prototype. * libdb/db_storage.h (struct mandata): Move to ... * lib/filenames.h (struct mandata): ... here. Add includes where necessary. 2022-09-23 Colin Watson Fix distcheck * po/POTFILES.in: Rename `src/compression.c` to `lib/compression.c`. 2022-09-23 Colin Watson Move compression file name utilities to lib/ This makes more sense as a home for plain file name manipulation utilities. I also merged `include/comp_src.h.in` into `lib/compression.c`, because structure definitions (as opposed to declarations) don't belong in header files. * src/compression.c: Move to ... * lib/compression.c: ... here. Remove unnecessary `pipeline.h` include. * src/compression.h: Move to ... * lib/compression.h: ... here. Update positioning of all includes. * lib/Makefile.am (libman_la_SOURCES): Add `compression.c` and `compression.h`. * lib/README: Add `compression.*`. * src/Makefile.am (lexgrog_SOURCES, man_SOURCES, man_recode_SOURCES, mandb_SOURCES): Remove `compression.c` and `compression.h`. * include/comp_src.h (comp_list): Move to ... * lib/compression.c (comp_list): ... here. Update all references. * include/manconfig.h (struct compression, comp_list): Move to ... * lib/compression.h (struct compression, comp_list): ... here. Add includes where necessary. * Makefile.am (noinst_HEADERS): Remove `include/comp_src.h`. 2022-09-23 Colin Watson Remove infoalloc macro It doesn't really pull its weight. * libdb/db_lookup.c (dblookup, dblookup_pattern): Call `XZALLOC (struct mandata)` rather than `infoalloc ()`. * src/man.c (try_section, do_global_apropos_section): Likewise. * libdb/db_storage.h (infoalloc): Remove. 2022-09-19 Colin Watson Maintain multi key references in sorted order This is a step towards being able to reproduce the same database given the same manual page tree. * bootstrap.conf (gnulib_modules): Add stpcpy. * libdb/db_lookup.c (name_ext_equals): Remove static; add pure attribute. (name_ext_compare): New function. (list_extensions): Add entries in sorted order. * libdb/db_storage.h (name_ext_equals, name_ext_compare): Add prototypes. * libdb/db_store.c (make_extensions_reference): New function. (dbstore): When building or updating multi key references, maintain them in sorted order. * NEWS.md: Document this. 2022-09-19 Colin Watson Remove some excessive debugging output This hasn't been of any practical use for many years. * lib/security.c (drop_effective_privs, regain_effective_privs): Remove debug messages emitted when increasing or decreasing the privilege drop count. 2022-08-11 Colin Watson 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.

This was magnificently obscure, at least to this Unix-head. Initially it appeared to be an issue with inter-library linking between libman and libmandb, but 2.9.4 relied on that too, just slightly less so. The actual problem was that libman only exported `gl_get_setlocale_null_lock` and not all the other symbols it's supposed to export, which is because that was explicitly marked for export and no other symbols were. Building libman with `-Wl,--export-all-symbols` fixes this; libman is intended as an aggregation of various helper functions, including those from Gnulib, and it doesn't make sense to be especially selective since it's only installed as a private library anyway. (I'm still not exactly sure why 2.9.4 didn't do the same thing, but this seems to be a good enough fix.) * configure.ac: Set LIBMAN_EXPORT_LDFLAGS to '-Wl,--export-all-symbols' when linking with GNU ld on Windows platforms. * lib/Makefile.am (libman_la_LDFLAGS): Add $(LIBMAN_EXPORT_LDFLAGS). * src/Makefile.am (LIBMAN): Remove $(top_builddir)/gl/lib/libgnu.la; as a convenience library, this is already incorporated into libman.la, and specifying it again causes multiple-definition errors on Cygwin. * src/tests/Makefile.am (get_mtime_LDADD): Likewise. * NEWS.md: Document this. 2022-02-08 Colin Watson Document fix for building without iconv * NEWS.md: Document previous change. 2022-02-08 Colin Watson Fix building without iconv * src/convert.c (convert_to_locale) [!HAVE_ICONV]: Declare a function rather than a macro.

Since man-db 2.5.6, this has interacted slightly poorly with the subpage feature, emitting spurious error messages if given multiple manual page arguments some of which include a slash. `man` no longer emits spurious error messages in this case. Fixes Savannah bug #53708. * src/man.c (man): Move name-contains-slash case to ... (man_maybe_local): ... here (new function).

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.

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.

Suggested by Steinar H. Gunderson. * src/manconfig.h (UNLIKELY): New macro. * src/decompress.c (decompress_inprocess_buf): New function. * src/decompress.h (decompress_inprocess_buf): Add prototype. * src/utf8.c, src/utf8.h: New files, based on glib's UTF-8 validation code. * src/manconv_client.c (manconv_inprocess): Optimize case where source_encoding is not UTF-8 and target_encoding is UTF-8 by returning early if UTF-8 validation passes. * src/Makefile.am (lexgrog_SOURCES, man_SOURCES, man_recode_SOURCES, mandb_SOURCES): Add utf8.c and utf8.h. 2022-01-24 Colin Watson 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. Fixes Debian bugs #630799 and #1003089, and Ubuntu bug #1858777. * NEWS.md: Document this. Bump version to 2.10.0. * src/decompress.c (enum decompress_tag): Add DECOMPRESS_INPROCESS. (struct decompress_inprocess): New structure. (struct decompress): Add an inprocess element.

Gunderson. * src/manconv_client.c (add_manconv): Return early if the source and target encodings are equal, not just if they're both UTF-8. 2022-01-22 Colin Watson Make manconv error handling less abrupt Exiting immediately on errors works OK if manconv is only ever used in a subprocess, but that approach makes it hard to use in an in-process context. * src/manconv.c (add_output): New function, factored out of try_iconv and manconv. (tried_iconv): New enumeration. (try_iconv): Use add_output. Return TRIED_ICONV_FATAL where we would previously have exited the process. (manconv): Use add_output. Return non-zero if add_output returns non-zero or try_iconv returns TRIED_ICONV_FATAL. * src/manconv.h (manconv): Update prototype. * src/manconv_client.c (manconv_stdin): Exit with FATAL if manconv returns non-zero. * src/manconv_main.c (main): Likewise. 2022-01-22 Colin Watson Clarify argument naming in add_manconv Suggested by Steinar H. Gunderson. * src/manconv_client.c (add_manconv): Rename source to source_encoding, and target to target_encoding. * src/manconv_client.h (add_manconv): Update prototype. 2022-01-19 Colin Watson 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 *`. * src/decompress.c (enum decompress_tag, struct decompress, decompress_new_pipeline, decompress_get_pipeline, decompress_start, decompress_read, decompress_peek, decompress_peek_skip, decompress_readline, decompress_peekline, decompress_wait, decompress_free): Add.

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 2010. * configure.ac (AM_MAINTAINER_MODE): Remove. 2022-01-17 Colin Watson NEWS.md: Document previous commit 2022-01-17 Colin Watson Merge branch 'C0rn3j-main-patch-74046' into 'main' man-db.timer: Use RandomizedDelaySec over AccuracySec See merge request cjwatson/man-db!1 2022-01-17 Colin Watson Avoid libpipeline linkage in libman Since it's only used by one function, and not all of man-db's tools need libpipeline in their own right (e.g. accessdb), it seems worth pushing this up a layer. * lib/encodings.c (struct conversion_entry, conversion_table, convert_encoding, check_preprocessor_encoding): Move to ... * src/manconv.c: ... here. * lib/encodings.h (check_preprocessor_encoding): Move to ... * src/manconv.h: ... here. * lib/Makefile.am (libman_la_CPPFLAGS): Remove $(libpipeline_CFLAGS).

(build-distcheck:artifacts): Add bootstrapped/*.tar.xz. 2022-01-02 Colin Watson Switch CI image to debian:unstable This gives us newer versions of various dependencies such as the autotools. * .gitlab-ci.yml (default:image): Switch from gcc to debian:unstable. (pre-commit:before_script, bootstrap:before_script): Explicitly install git. 2022-01-02 Colin Watson Pacify gcc -fanalyzer in manconv * src/manconv_main.c (main): Assert that from_code is non-NULL; this is guaranteed by the argp state machine, but the compiler can't prove that. 2022-01-02 Colin Watson Fix crash in globbing if run with no arguments * src/globbing_test.c (parse_opt): Emit a usage message if there are no non-option arguments. (main): Assert that remaining_args is non-NULL; this is now guaranteed by the argp state machine, but the compiler can't prove that. * NEWS: Document this. 2022-01-02 Colin Watson Pacify gcc -fanalyzer in catman It isn't actually possible for sections to be NULL after argp parsing has finished, but "gcc -fanalyzer" can't easily determine that, and it's easy enough to arrange for it not to matter. * src/catman.c (main): Handle case where sections is NULL. 2022-01-02 Colin Watson Pacify gcc -fanalyzer in some database functions In GCC 11.2.0, -fanalyzer seems to get confused by copies by assignment of "struct datum", and thinks that there are use-after-free or double-free possibilities with multiple loop iterations. These seem to be false positives, so ignore them for now. * libdb/db_lookup.c (dblookup_pattern): Ignore false use-after-free diagnostic. * src/accessdb.c (main): Ignore false double-free diagnostics. * src/catman.c (parse_for_sec): Ignore false use-after-free diagnostics. * src/check_mandirs.c (sanity_check_db): Ignore false double-free diagnostics. (purge_pointers, purge_missing): Ignore false use-after-free diagnostics. * src/whatis.c (do_apropos): Ignore false use-after-free and double-free diagnostics. 2022-01-02 Colin Watson Pacify gcc -fanalyzer in dbdelete The refs list can't in fact be empty by this point (because we checked earlier that we could look up this_ref in it), but it's hard for "gcc -fanalyzer" to prove that, so help it understand that multi_content can never end up being NULL. * libdb/db_delete.c (dbdelete): Initialize multi_content before looping over refs. 2022-01-02 Colin Watson Assert that some xasprintf calls return non-NULL "gcc -fanalyzer" notices that xasprintf can return NULL in some situations (string length > INT_MAX, invalid format string, or multibyte conversion error), and that we weren't handling this in various cases where we use the return value in contexts that require non-NULL values. The situations seem obscure enough for simple asserts to be appropriate. * lib/pathsearch.c (pathsearch): Assert that xasprintf returns non-NULL. * lib/tempfile.c (create_tempdir): Likewise. * lib/util.c (remove_directory): Likewise. * libdb/db_lookup.c (make_multi_key): Likewise. * libdb/db_store.c (make_content, dbstore): Likewise. * src/check_mandirs.c (add_dir_entries, fix_permissions_tree): Likewise. * src/compression.c (comp_file): Likewise. * src/globbing.c (look_for_file): Likewise. * src/man.c (main): Likewise. * src/mandb.c (mandb, purge_catsubdirs): Likewise. * src/manp.c (pathappend): Likewise. * src/ult_src.c (find_include): Likewise. * src/whatis.c (use_grep): Likewise. * src/zsoelim.l (zsoelim_open_file): Likewise. 2022-01-02 Colin Watson Fix path searching crash if getcwd fails xgetcwd can return NULL if getcwd returns NULL for reasons other than ENOMEM, so we should handle this. Found by "gcc -fanalyzer". * lib/pathsearch.c (pathsearch, directory_on_path): Emit a fatal error if xgetcwd returns NULL. * po/POTFILES.in: Add lib/pathsearch.c. * NEWS: Document this. 2022-01-02 Colin Watson Update to Gnulib 20211231 In line with Gnulib, we now require Autoconf 2.64. * bootstrap: Sync to Gnulib 14db2b71b5bd05b94ec6126617fd32cd5f1016cd. * bootstrap.conf (GNULIB_REVISION): Set to 14db2b71b5bd05b94ec6126617fd32cd5f1016cd. (buildreq): Bump required autoconf version to 2.64. * configure.ac (AC_PREREQ): Bump to 2.64. (--enable-gcc-warnings): New option, based on code in coreutils. Use this to enable -fanalyzer only if --enable-gcc-warnings=expensive is used; it's useful but slow. * include/manconfig.h.in (create_tempdir, appendstr): Move NODISCARD to the start of these function declarations, required by draft C2x. * patches/argp-domain.patch: Rebase. * NEWS: Document this. 2022-01-02 Colin Watson Fix NULL dereference in get_locale_charset callers * lib/encodings.c (get_canonical_charset_name): Declare argument and return value as non-NULL. (get_locale_charset): Declare return value as non-NULL. Fall back to "ANSI_X3.4-1968" if locale_charset returned NULL or the empty string. 2022-01-02 Colin Watson Trim down direct Gnulib dependencies a little * bootstrap.conf (gnulib_modules): Add c99 (already used indirectly, but seems like a good idea to request directly now). Remove getopt-gnu, lock, and unsetenv, none of which we use directly. Replace fcntl with fcntl-h and signal with signal-h, since we use the corresponding header files directly but not the corresponding functions. * .gitignore: Remove lib/getopt.h. 2022-01-01 Colin Watson Fix warnings with Autoconf >= 2.70 * configure.ac (AC_PROG_LEX): Add noyywrap argument (new in Autoconf 2.70, but ignored in previous versions). * m4/man-bdb.m4 (MAN_CHECK_BDB): Autoconf 2.70 warns about non-literal arguments to AC_CHECK_HEADERS. Refactor loops so that the header and library names are visible to m4. 2022-01-01 Colin Watson Add an SC_ALLOW_PERMISSIVE macro This plays slightly better with clang-format. * lib/sandbox.c (SC_ALLOW_PERMISSIVE): New macro. (make_seccomp_filter): Use SC_ALLOW_PERMISSIVE instead of forms such as "if (permissive) SC_ALLOW (name);". 2022-01-01 Colin Watson Use Gnulib attribute.h properly manconfig.h previously used _GL_ATTRIBUTE_FORMAT_PRINTF_SYSTEM without first including "stdio.h", which caused build failures. We should be using the public names anyway. * bootstrap.conf (gnulib_modules): Add attribute. * include/manconfig.h.in (create_tempdir, appendstr): Use NODISCARD rather than _GL_ATTRIBUTE_NODISCARD. * include/manconfig.h.in (debug, debug_error): Use ATTRIBUTE_FORMAT rather than _GL_ATTRIBUTE_FORMAT_PRINTF_SYSTEM. * lib/debug.c (vdebug): Likewise. * include/manconfig.h.in (appendstr): Use ATTRIBUTE_SENTINEL rather than _GL_ATTRIBUTE_SENTINEL. * lib/encodings.c (get_page_encoding): Use ATTRIBUTE_MALLOC rather than _GL_ATTRIBUTE_MALLOC. * lib/util.c (trim_spaces): Likewise. * lib/encodings.c (is_roff_device, get_output_encoding, get_less_charset, get_jless_charset): Use ATTRIBUTE_PURE rather than _GL_ATTRIBUTE_PURE. * lib/glcontainers.c (string_equals, string_hash): Likewise. * lib/security.c (running_setuid): Likewise. * src/manp.c (canonicalized_path_equals, canonicalized_path_hash): Likewise. * src/whatis.c (match): Likewise. * libdb/db_lookup.c (dash_if_unset): Use ATTRIBUTE_CONST rather than _GL_ATTRIBUTE_CONST. * libdb/db_store.c (compare_ids): Likewise. 2022-01-01 Colin Watson Reduce indentation depth using C99 * src/man.c (parse_opt): Remove an enclosing block and associated indentation level, since C99 allows mixing declarations and code. 2022-01-01 Colin Watson Pacify pre-commit * lib/mp.h: Remove trailing whitespace. 2022-01-01 Colin Watson Simplify interface to container iterator macros The Gnulib container iterator macros (GL_LIST_FOREACH_* and GL_MAP_FOREACH_*) have to run code both before and after a chunk of user-supplied code. This previously required a START/END macro pair used something like this: GL_LIST_FOREACH_START (names, name) { ... } GL_LIST_FOREACH_END (names); This doesn't look natural in C, and so it was easy to get it wrong. It's possible to do better, at the cost of some tricky macros. Fortunately, Simon Tatham has already done the hard work in https://www.chiark.greenend.org.uk/~sgtatham/mp/, and the necessary header file is MIT-licensed, so we can incorporate it. Now these iterator macros are used more like this, which is a much more natural C style: GL_LIST_FOREACH (names, name) { ... } * lib/mp.h: New file. * lib/Makefile.am (libman_la_SOURCES): Add mp.h. * lib/README: Add mp.h. Rephrase introductory text about licensing to account for an MIT-licensed file. * lib/glcontainers.h (GL_LIST_FOREACH_START, GL_LIST_FOREACH_END): Rewrite as ... (GL_LIST_FOREACH): ... this. Update all callers. (GL_MAP_FOREACH_START, GL_MAP_FOREACH_END): Rewrite as ... (GL_MAP_FOREACH): ... this. Update all callers. * NEWS, README.md, docs/HACKING: Document C99 compiler requirement. 2022-01-01 Colin Watson Simplify some GCC attribute handling * include/manconfig.h.in (ATTRIBUTE_FORMAT_PRINTF, ATTRIBUTE_WARN_UNUSED_RESULT, ATTRIBUTE_SENTINEL): Remove in favour of Gnulib-provided macros. (create_tempdir, appendstr): Use _GL_ATTRIBUTE_NODISCARD rather than ATTRIBUTE_WARN_UNUSED_RESULT. (debug, debug_error): Use _GL_ATTRIBUTE_FORMAT_PRINTF_SYSTEM rather than ATTRIBUTE_FORMAT_PRINTF. (appendstr): Use _GL_ATTRIBUTE_SENTINEL rather than ATTRIBUTE_SENTINEL. * lib/debug.c (vdebug): Use _GL_ATTRIBUTE_FORMAT_PRINTF_SYSTEM rather than ATTRIBUTE_FORMAT_PRINTF. 2022-01-01 Colin Watson Introduce pre-commit * .pre-commit-config.yaml: New file. * .gitlab-ci.yml (stages): Add bootstrap. (pre-commit): New job. (bootstrap): Move to bootstrap stage. Remove trailing whitespace from all files. 2022-01-01 Colin Watson Update licence texts There are no substantive licensing changes here, only formatting adjustments and referring to the "GNU Lesser General Public License" rather than the "GNU Library General Public License". * docs/COPYING: Update from current contents of https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt. * docs/COPYING.LIB: Update from current contents of https://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt. 2021-12-31 Colin Watson Document migration to GitLab * README.md: Add link to GitLab repository.

Reformat as Markdown. * Makefile.am (dist_noinst_DATA): Replace README with README.md. * docs/INSTALL.quick: Likewise. 2021-11-16 Colin Watson Add .gitlab-ci.yml 2021-09-19 Colin Watson Update some obsolete Autoconf macros * configure.ac: Replace AC_GNU_SOURCE and AC_ISC_POSIX with AC_USE_SYSTEM_EXTENSIONS. Replace AC_CONFIG_HEADER with AC_CONFIG_HEADERS. Remove an obsolete comment. 2021-09-19 Colin Watson Stop using obsolete AC_TRY_LINK This has been obsolete since Autoconf 2.55. Use its AC_LINK_IFELSE expansion instead. * m4/man-bdb.m4 (MAN_CHECK_BDB): Expand AC_TRY_LINK call using AC_LINK_IFELSE. 2021-09-18 Mario Blättermann Update German manual page translation * man/po4a/po/de.po: Update from Translation Project. 2021-09-18 Mario Blättermann Update German manual page translation * man/po4a/po/de.po: Update from Translation Project. 2021-07-11 Colin Watson Fix mishandling of suffix matches in manpath Fixes Savannah bug #60906. * src/manp.c (pathappend): strstr might return matches that are not at the start of a manpath element, resulting in incorrect truncation. Skip any such matches. 2021-02-08 Colin Watson Release man-db 2.9.4 2021-02-08 Colin Watson Fix distribution of Romanian manual page translation Accidentally omitted from 1c7b46aecbed76c9833e0a5c833fc2ffd1a7a85a. * man/Makefile.am (DIST_SUBDIRS): Add ro. 2021-02-08 Мирослав Николић Update Serbian manual page translation * man/po4a/po/sr.po: Update from Translation Project. 2020-12-11 Mario Blättermann Update German manual page translation * man/po4a/po/de.po: Update from Translation Project. 2020-09-13 Colin Watson Handle \[en] escapes in NAME section Fixes Debian bug #970122. * src/lexgrog.l (MAN_NAME): Treat "\[en]" (and similar) as another synonym for "\-", and thus as a separator. (This spelling is groff-specific; the older "\(en" spelling was already accepted.) * NEWS: Document this. 2020-08-22 Colin Watson Fix gcc -Wzero-length-bounds warning * lib/orderfiles.c (order_files): Avoid accessing an element of a zero-length array. 2020-08-22 S. Gilles Allow clock_gettime64; return ENOSYS so libcs can engage fallbacks libcs such as musl expect ENOSYS to be returned (not EPERM) in their fallback code, so change the seccomp filter to be more agreeable to them. At the same time, clock_gettime is permitted in the filter, so permit clock_gettime64 as well -- it will be needed by 2038 in any case. * lib/sandbox.c (make_seccomp_filter): Set default action to SCMP_ACT_ERRNO (ENOSYS). Allow clock_gettime64. * NEWS: Document this. 2020-07-04 Colin Watson Add Romanian manual page translation * man/po4a/po/ro.po: New from Translation Project (thanks, Florentina Mușat). * configure.ac (AC_CONFIG_FILES): Add man/ro/Makefile. * man/LINGUAS.po4a: Add ro. * man/Makefile.am (DIST_SUBDIRS): Add ro. * man/ro/Makefile.am, man/ro/translator.add: New files. * man/po4a/Makefile.am (POFILES): Add po/ro.po. * man/po4a/po4a.cfg (po4a_langs): Add ro. * man/THANKS: Update translator credit. * .gitignore: Add man/ro/man1, man/ro/man5, and man/ro/man8. 2020-07-04 Colin Watson Remove "Type" column from DB table in mandb(8) The database types table in mandb(8) has always been a bit dubiously-placed; it's really more about how man-db is configured, and as such makes more sense in manual/db.me (which indeed has an extended version of the same table). It causes particular problems in translated versions of this page, where it's very easy for it to become too wide and cause "make check" failures. A proper fix for this would probably require updating existing translations, but an easy improvement is to remove the "Type" column: it has negligible relevance here, and removing it makes it much easier for translated versions to stay within page width limits. * man/man8/mandb.man8 (DATABASE CACHES): Remove "Type" column from table. 2020-07-02 Colin Watson Recognise Romanian translations of NAME * src/lexgrog.l (ro_name): Add. (name): Add ro_name. * NEWS: Document this. 2020-06-24 Florentina Mușat Update Romanian translation * po/ro.po: Update from Translation Project. * man/THANKS: Add translator credit. 2020-06-22 Colin Watson Release man-db 2.9.3 2020-06-22 Colin Watson 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 Fix po4a version comparison po4a's versions don't quite conform to Perl's standard versioning arrangements, producing very confusing results when trying to compare two-component and three-component versions (because "0.47" is equivalent to "v0.470.0"). Perhaps we should use some other version comparison system instead, but in the meantime patch things up so that what we currently use behaves more sensibly. * man/po4a/Locale/Po4a/Manext.pm (_parse_version): New subroutine. (shiftline, pushline, translate): Use _parse_version, and always use a leading "v" on the right-hand side. 2020-06-01 Colin Watson Clarify description of zstd in configure Suggested by crabbed halo ablution in Savannah bug #57558. * configure.ac: Describe zstd as "LZ77/entropy-coding compression utility". 2020-06-01 Colin Watson Release man-db 2.9.2 2020-06-01 Colin Watson Update to Gnulib 20200531 * bootstrap: Sync to Gnulib d4429157c13b49d1749f5ea18fb30e24ffa646aa. * bootstrap.conf (GNULIB_REVISION): Set to d4429157c13b49d1749f5ea18fb30e24ffa646aa. 2020-06-01 Bernhard Rosenkränzer Add support for zstd-compressed manual pages * configure.ac: Check for zstd. * include/comp_src.h.in (comp_list): Add zstd. * include/manconfig.h.in: Define UNZSTD. * NEWS: Document this. 2020-05-31 Colin Watson 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. 2020-05-31 Colin Watson 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.

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.

(get_manpath_from_path): Remove extra newlines before "path directory %s" and "adding mandatory man directories". (add_expanded_dir_to_list): Remove noisy "%s is already in the manpath" debugging output. Indent "adding %s to manpath" by two spaces. (add_man_subdirs): Remove noisy "and doesn't have ../man, man, ../share/man, or share/man subdirectories" debugging output. 2019-09-08 Colin Watson Refactor deduplication in create_pathlist This is more efficient, and also has the useful side-effect of reducing noise in debug output. * src/manp.c (struct canonicalized_path): New structure. (canonicalized_path_new, canonicalized_path_equals, canonicalized_path_hash, canonicalized_path_free): New functions. (add_dir_to_path_list): Canonicalize the given path and (if it exists) add both the original and canonicalized versions as a pair. (create_pathlist): Simplify: rather than doing a second quadratic-time pass to eliminate duplicates, we now avoid inserting them in linear time as we go along. 2019-09-08 Colin Watson man(1): Explain interactions between -w/-W and -a Reported by Bjarni Ingi Gislason. Fixes Debian bug #803712. * man/man1/man.man1 (Main modes of operation): Explain that the -w and -W options only print a single match by default, but that -a can be used to print all matches. 2019-09-08 Colin Watson Suggest "man man" if run with no arguments Fixes Debian bug #869798. * src/man.c (gripe_no_name): Suggest running "man man". * NEWS: Document this. 2019-09-08 Colin Watson * NEWS: Document recent manual page improvements. 2019-09-08 Colin Watson Mention where other manual pages come from * man/man1/man.man1 (OVERVIEW): Explain that individual manual pages normally come with whatever they document. 2019-09-08 Colin Watson 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 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 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. 2019-09-08 Colin Watson Tidy up formatting of Wilf's name Based on similar changes elsewhere by Bjarni Ingi Gislason. * man/man1/lexgrog.man1 (AUTHOR): Protect "." with "\&" if it is followed by a space and does not mean the end of a sentence. * man/man1/manpath.man1 (AUTHOR): Likewise. * man/man1/whatis.man1 (AUTHOR): Likewise. * man/man1/zsoelim.man1 (AUTHOR): Likewise. * man/man8/accessdb.man8 (AUTHOR): Likewise. * man/man8/catman.man8 (AUTHOR): Likewise. * man/man8/mandb.man8 (AUTHOR): Likewise. 2019-09-08 Bjarni Ingi Gislason manpath(1): Correct some typographic mistakes Fixes Debian bug #927452. * man/man1/manpath.man1 (DESCRIPTION): Use \(en for a dash where appropriate. (OPTIONS): Change .BR to .B if there is only one argument. 2019-09-08 Bjarni Ingi Gislason apropos(1): Minor typographic changes Fixes Debian bug #892421. * man/man1/apropos.man1 (DESCRIPTION): Use "\e" to print the escape character instead of "\\" (which is interpreted in copy mode). (OPTIONS): Change .BR to .B if there is only one argument. (FILES): Add a space around "|" to increase readability. (AUTHOR): Protect "." with "\&" if it is followed by a space and does not mean the end of a sentence. 2019-09-08 Colin Watson Apply italic corrections Partly based on suggestions from Bjarni Ingi Gislason in Debian bug #892421, although I had to take a slightly different approach to avoid confusing po4a. * man/man1/apropos.man1 (OPTIONS): Apply italic corrections to descriptions of --sections and --systems. Simplify three-font handling for --systems. * man/man1/man.man1 (Finding manual pages): Likewise. * man/man1/whatis.man1 (OPTIONS): Likewise. * man/man1/manpath.man1 (OPTIONS): Apply italic corrections to description of --systems, and simplify three-font handling. 2019-09-07 Colin Watson man(1): Adjust description of section 5 * man/man1/man.man1 (DESCRIPTION): Add a comma before "e.g.". 2019-09-07 Bjarni Ingi Gislason man(1): Minor typographic changes Fixes Debian bug #892230. * man/man1/man.man1 (DESCRIPTION, HISTORY): Protect "." with "\&" if it is followed by a space and does not mean the end of a sentence. (EXAMPLES): Use a macro to change to the italic font instead of \fI if possible. The macros have the italic corrections. (EXAMPLES, Controlling formatted output, Getting help, SEE ALSO): Change .BR/.IR to .B/.I if there is only one argument, or else separate the second argument from the first if needed. (DEFAULTS): Begin each sentence on a new line. (FILES): Add a space around "|" to increase readability. 2019-09-07 Colin Watson Make long lines in man(1) less likely Fixes part of Debian bug #892230. * man/man1/man.man1 (DESCRIPTION, ENVIRONMENT): Put the expansion of %sections% on its own line. 2019-09-07 Colin Watson Escape %troff% expansion correctly in manual pages Fixes part of Debian bug #892230. * configure.ac: Substitute troff_as_troff_input, which is the same as troff but with suitable escaping so that "groff -mandoc" turns into "groff \-mandoc". * man/replace.sin.in (%troff%): Substitute @troff_as_troff_input@ rather than @troff@. 2019-09-07 Colin Watson Remove trailing whitespace from manual pages * man/man1/apropos.man1, man/man1/lexgrog.man1, man/man1/man.man1, man/man1/manpath.man1, man/man1/whatis.man1, man/man1/zsoelim.man1, man/man5/manpath.man5, man/man8/accessdb.man8, man/man8/catman.man8, man/man8/mandb.man8: Remove trailing whitespace. 2019-09-07 Sebastian Rasmussen Fix trivial typo in man manpage Fixes Savannah bug #48663. * man/man1/man.man1: an -> and. 2019-09-07 Colin Watson Remove stray words from man(1) Reported by Bjarni Ingi Gislason.

However, at least when using GDBM's NDBM compatibility interface, this may be true for NDBM too. Extend the manual result ordering code to cover both of these backends. * libdb/db_gdbm.c (parent_keys, datum_compare, datum_equals, datum_hash, datum_free, empty_datum, man_gdbm_firstkey, man_gdbm_nextkey, man_gdbm_close): Move to ... * libdb/db_xdbm.c (parent_keys, datum_compare, datum_equals, datum_hash, datum_free, empty_datum, man_xdbm_firstkey, man_xdbm_nextkey, man_xdbm_close): ... here (new file). * libdb/db_xdbm.h: New file. * libdb/db_gdbm.c (unsorted_firstkey, unsorted_nextkey, raw_close): New functions, wrapping gdbm_firstkey, gdbm_nextkey, and gdbm_close respectively.

Rename libmandb's various backend-specific functions to be uniformly man__. In the cases of btree and ndbm there was already no clash with the libraries they depend on, but this makes them match the gdbm backend. * libdb/db_btree.c (btree_close): Rename to ...

No functional change. * lib/sandbox.c (make_seccomp_filter): Reorganise using systemd's new @system-service set. 2019-08-21 Colin Watson sandbox: Set default action to EPERM, not TRAP Returning EPERM rather than raising SIGSYS is no less secure, and it's more likely that code injected via LD_PRELOAD will be able to recover from this somehow. * lib/sandbox.c (make_seccomp_filter): Set default action to SCMP_ACT_ERRNO (EPERM), not SCMP_ACT_TRAP. 2019-08-14 Colin Watson sandbox: Allow sendmsg in the ESET case * lib/sandbox.c (make_seccomp_filter): If libesets_pac.so is preloaded, then allow sendmsg. * NEWS: Document this. 2019-08-05 Colin Watson * Version: 2.8.6.1. 2019-08-04 Colin Watson Fix missing memory copies in ult_src Fixes Debian bug #933802. * src/ult_src.c (ult_src): Copy strings before adding them to trace. 2019-08-03 Colin Watson * Version: 2.8.6. 2019-08-03 Colin Watson Update syscall lists from systemd bca5a0eacc * lib/sandbox.c (make_seccomp_filter): Add rseq (see https://github.com/systemd/systemd/issues/12127). 2019-05-02 Colin Watson Improve manual build portability slightly * manual/Makefile.am ($(MANUAL).pp, .pp.dvi, .pp.ps, .pp.tdvi, .tdvi.tps, .pp.cat, .pp.html): Use "mv -f" rather than just "mv", since Automake seems to prefer that for its own rules. 2019-05-02 Colin Watson Make manual build more robust against failures Fixes Savannah bug #56254. * manual/Makefile.am ($(MANUAL).pp, .pp.dvi, .pp.ps, .pp.tdvi, .tdvi.tps, .pp.cat, .pp.html): Write output to *.new files and rename into place, so that failures are properly retried in future runs. 2019-03-03 Colin Watson Avoid configure error message if nroff is broken * m4/man-gnu-nroff.m4 (MAN_PROG_GNU_NROFF): Adjust test arguments slightly to avoid a spurious error message if nroff is sufficiently broken that it doesn't produce numeric output for "\n(.g". 2019-03-03 Colin Watson Fix warnings when configuring --without-libseccomp * lib/sandbox.c (_sandbox_load): Mark sandbox and permissive parameters unused when HAVE_LIBSECCOMP is undefined, to avoid warnings from "gcc -Wunused-parameter". 2019-03-03 Colin Watson Add configure option to disable building manual * m4/man-arg-manual.m4: New file. * configure.ac: Add MAN_ARG_MANUAL. * manual/Makefile.am: Perform most rules only if BUILD_MANUAL is true. * manual/intro.me (Arguments to configure): Add --disable-manual. * README (Non-generic arguments to configure): Update. * NEWS: Document this. 2019-03-03 Colin Watson * NEWS: Document container type changes. 2019-02-05 Colin Watson Add some missing entries to lib/README * lib/README: Add glcontainers.*, orderfiles.*, and sandbox.*. 2019-02-05 Colin Watson Remove pipeline.* from lib/README It's been a separate library since 2010. * lib/README: Remove pipeline.*. 2019-02-05 Colin Watson Inline lower into name_to_key With only one remaining user, it wasn't pulling its weight. * libdb/db_lookup.c (name_to_key): Inline the implementation of lower. * lib/Makefile.am (libman_la_SOURCES): Remove lower.c and lower.h. * lib/README: Remove lower.*. * lib/lower.c, lib/lower.h: Remove. 2019-02-05 Colin Watson 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 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.

Fixes Debian bug #913721. * src/man.c (check_standard_fds): Correct error message if stdout is not open for writing (not "for reading", as previously claimed). 2018-11-09 Colin Watson release.sh: Simplify Lex handling release.sh had a hack to ensure that flex-generated scanners are fresh in release tarballs. This is more easily achieved by configuring with --enable-maintainer-mode, which causes Automake to enable the Lex rebuild rule. * release.sh: Configure with --enable-maintainer-mode; drop conditional removals of src/lexgrog.c and src/zsoelim.c. 2018-11-09 Colin Watson 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).

We now issue a warning in the same way that commit_tmp_cat does. * src/man.c (cleanup_unlink): New function.

This was broken by the working-directory-handling changes in 2.8.3. Reported by Josh Triplett. Fixes Debian bug #901007. * src/man.c (NFMT_PROG, TFMT_PROG): Remove leading "./". (make_roff_command): Refactor confusing #ifdef forest. Prefix dir to TFMT_PROG/NFMT_PROG rather than looking in the current directory. Don't look for an external formatter at all if dir is NULL. * NEWS: Document this. 2018-06-08 Colin Watson 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.

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.

Sure, other pagers may be selected in aforementioned ways, but then the defaults are overridden, making that unsuitable for install-time configuration. This patch makes man check (if that becomes relevant) if PAGER is executable, further defaulting to cat (which is basically ubiquitous, being in original Unix, POSIX, and GNU Coreutils) if it is not. Thus the poor beginner Unix users without less installed will be able to get man pages. * src/man.c (sh_lang_first_word): New function.

Fix this. See: https://savannah.gnu.org/bugs/?44941 * src/man.c (display): Pass bits.language rather than page_lang to locale_macros. Adjust memory allocation. 2016-12-13 Colin Watson Rename SECURE_MAN_UID to MAN_OWNER The latter had always been defined to the former anyway, and now that the cache owner can be changed without actually installing setuid the latter is more descriptive. * m4/man-arg-cache-owner.m4: Define MAN_OWNER rather than SECURE_MAN_UID.

Simplify "GNU gdbm v >= 1.6" to "GNU gdbm". Update all translations. 2016-12-11 Colin Watson Fix table rendering with po4a 0.47 * man/po4a/Locale/Po4a/Manext.pm (initialize): Drop unused assignment. (shiftline, pushline): Pass through to superclass if po4a version >= 0.47.

Instead, configure with --disable-setuid during distcheck. * Makefile.am (AM_DISTCHECK_CONFIGURE_FLAGS): Add --disable-setuid. 2016-12-11 Colin Watson Update translation files * po/man-db.pot, po/*.po: Update. * man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update. 2016-12-11 Colin Watson * NEWS: Document changes since 2.7.5. 2016-12-11 Mihail Konev src/tests: Use /tmp for temporary directories Reduces disk reads/writes made by 'make check -C src'. Fall back to ./tmp-* if 'mktemp -d' fails. 2016-12-10 Colin Watson 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 Make --disable-cache-owner imply --disable-setuid * m4/man-arg-setuid.m4: Set man_mode="755" if --disable-cache-owner was given and neither --enable-setuid nor --disable-setuid was given. 2016-12-10 Colin Watson Update manual for cache-owner/setuid changes * manual/intro.me (Arguments to configure): Add --enable-cache-owner and --disable-cache-owner. Remove --enable-setuid[=ARG]. Adjust description of --disable-setuid. * manual/misc.me (Modes of operation): Add --disable-cache-owner to the non-setuid modes. Mention --enable-setuid rather than --enable-setuid=USER. * README (Non-generic arguments to configure): Update. 2016-12-10 Colin Watson 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 Handle cleanup stack more safely If push_cleanup was called unexpectedly between a push_cleanup/pop_cleanup pair, then the pop_cleanup would remove the wrong cleanup function and chaos could ensue. Avoid this by being more precise about which cleanup function should be popped. * lib/cleanup.c (pop_cleanup): Take "fun" and "arg" arguments. Pop the topmost matching function from the stack, rather than just the topmost function. Update all callers and prototypes. 2016-12-09 Colin Watson Upgrade config.guess/config.sub * build-aux/config.guess: Upgrade to 2016-10-02. * build-aux/config.sub: Upgrade to 2016-11-04. 2016-12-09 Colin Watson Separate cache owner from --enable-setuid option It's useful to have a notion of the cache owner even when man is not installed setuid. --enable-setuid no longer takes an argument, and the owner is now set by the --enable-cache-owner option instead. * m4/man-arg-cache-owner.m4: New file. * m4/man-arg-setuid.m4: Stop accepting an argument. Only set man_mode, not man_owner. * configure.ac: Call MAN_ARG_CACHE_OWNER. * src/Makefile.am (install-exec-hook): Only chown man and mandb if man_mode is 4755 (as well as the existing test for man_owner being non-empty). 2016-11-21 Colin Watson Restore ylwrap to distribution * Makefile.in (am__DIST_COMMON): Regenerate to add build-aux/ylwrap back again, since it mysteriously went missing in the last regeneration. 2016-11-21 Colin Watson Update translation files * po/man-db.pot, po/*.po: Update. 2016-11-21 Colin Watson Upgrade to Libtool 2.4.6-2 (from Debian) 2016-11-21 Colin Watson Upgrade config.guess/config.sub * build-aux/config.guess: Upgrade to 2016-04-02. * build-aux/config.sub: Upgrade to 2016-03-30. 2016-11-20 Mihail Konev src/tests: Fix testsuite * src/tests/man-9: Set MANPATH. 2016-11-20 Mihail Konev man(1): Fix gcc warnings * lib/xchown.c: New file. * lib/xchown.h: New file. * lib/Makefile.am (libman_la_SOURCES): Add xchown.c and xchown.h. * po/POTFILES.in: Add lib/xchown.c. * src/check_mandirs.c (mkcatdirs): Call xchown instead of chown. * src/man.c (format_display): Ignore errors from chdir ("/"). 2016-11-20 Colin Watson Make split_page_name allocate its own memory * src/man.c (split_page_name): Allocate *ret_name and *ret_section here.

(main): Call it rather than using freopen. 2014-11-16 Colin Watson Allow building from git without gnulib-tool Since we don't want to keep Gnulib translations in revision control, we need gnulib-tool on $PATH when generating the build system in order to fetch them, but it's unnecessarily awkward to require everyone to have this just in order to build man-db from git. Allow building without this, although it is still required for "make dist". * configure.ac: No longer issue an error if gnulib/po/Makefile.in.in is missing. Instead, set the Automake conditional HAVE_GNULIB_PO to true if and only if gnulib/po/POTFILES.in exists, and only create gnulib/po/Makefile.in if gnulib/po/Makefile.in.in exists. * Makefile.am (SUBDIRS): Only include gnulib/po if HAVE_GNULIB_PO is true. 2014-11-14 Colin Watson apropos/whatis: Don't truncate names if long output was requested * src/whatis.c (display): Leave page_name intact if long_output is true.

(AM_CPPFLAGS): Adjust ZSOELIM definition to match. * NEWS: Document this. 2014-09-18 Colin Watson Rename SOELIM definition to ZSOELIM for clarity * src/Makefile.am (AM_CPPFLAGS): Define ZSOELIM rather than SOELIM. * src/man.c (make_roff_command): Use ZSOELIM rather than SOELIM. 2014-09-17 Colin Watson Make sure that generated shared libraries have no undefined symbols Based on a change found in https://github.com/Alexpux/MSYS2-packages/tree/master/man-db. * lib/Makefile.am (libman_la_LDFLAGS): Add -no-undefined. * libdb/Makefile.am (libmandb_la_LDFLAGS): Add -no-undefined. 2014-09-17 Colin Watson Correct a couple of comments in m4/man-arg-*.m4 * m4/man-arg-automatic-update.m4: Correct header comment. * m4/man-arg-systemdtmpfilesdir.m4: Likewise. 2014-09-17 Colin Watson Fix "cannot adjust line" warning when formatting db.me * manual/db.me (Contents of an index database): Insert several zero-width break points in descriptions of entry formats. 2014-09-17 Colin Watson Show a better error message if no browser is configured Fixes Savannah bug #37814. * src/man.c (format_display): Adjust error message if html_pager is NULL or the empty string. * NEWS: Document this. 2014-09-17 Colin Watson Don't store canonicalised versions of manpath elements We still compare canonicalised versions, but don't store them. Storing them results in looking up the wrong catpath in the case where one of the configured MANDB_MAP entries is a symlink. Broken by commit 01e5a4febfc7b6cd53991455315ae7744c8f31dd; fixes Fedora bug #1043401. * src/manp.c (create_pathlist): Compare canonicalised versions of manpath elements, but don't store them. * NEWS: Document this. 2014-09-16 Colin Watson Don't use pointed-to name as title for database-located pages For a pointer record, the pointed-from name is a legitimate alias for the located page, and is likely to be closer to the name that the user requested. Fixes Debian bug #709405. * src/man.c (display_database): Don't use the pointed-to name to construct the title for display. 2014-09-16 Colin Watson * Version: 2.7.0-pre1. 2014-09-16 Colin Watson Fix distcheck following addition of systemd tmpfiles snippet * Makefile.am (AM_DISTCHECK_CONFIGURE_FLAGS): Add --with-systemdtmpfilesdir=\$${prefix}/lib/tmpfiles.d. 2014-09-16 Bjarni Ingi Gislason Formatting improvements to man(1) Fixes Debian bug #726266. * man/man1/man.man1: Protect "." at beginning or end of strings with "\&". Start sentences on new lines. Insert italic corrections between adjacent italic and roman characters. Use double quotation marks around arguments rather than placing "\ " between strings. * man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update. 2014-09-16 Colin Watson Prioritise COLUMNS above TIOCGWINSZ Fixes Ubuntu bug #1315282. * lib/linelength.c (get_line_length): Prioritise COLUMNS above TIOCGWINSZ. * man/man1/apropos.man1 (DESCRIPTION): Describe new terminal width priorities. * man/man1/man.man1 (DESCRIPTION): Likewise. * man/man1/whatis.man1 (DESCRIPTION): Likewise. * man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update. * NEWS: Document this. 2014-09-16 Colin Watson Use xnrealloc rather than xrealloc in a few more places * src/catman.c (parse_opt): Use xnrealloc rather than xrealloc. * src/globbing.c (update_directory_cache): Likewise. * src/ult_src.c (ult_trace): Likewise. 2014-09-16 Colin Watson 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.

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 cope with mutual recursion. (do_prompt): Move to immediately above display. * src/man.h: Remove. * src/Makefile.am (man_SOURCES): Remove man.h. 2014-09-15 Colin Watson Move argument handling out of configure to new MAN_ARG_* macros * m4/man-arg-automatic-create.m4, m4/man-arg-automatic-update.m4, m4/man-arg-cats.m4, m4/man-arg-config-file.m4, m4/man-arg-db.m4, m4/man-arg-device.m4, m4/man-arg-mandirs.m4, m4/man-arg-override-dir.m4, m4/man-arg-sections.m4, m4/man-arg-setuid.m4, m4/man-arg-systemdtmpfilesdir.m4, m4/man-arg-undoc.m4: New files. * configure.ac: Call new macros rather than inlining argument handling. 2014-09-15 Colin Watson * build-aux/config.sub: Upgrade to 2014-09-11. 2014-09-12 Colin Watson Simplify handling using Gnulib * gnulib: Import dirent module. * configure.ac: Remove obsolescent AC_HEADER_DIRENT macro. * src/check_mandirs.c: Simplify a large conditional block to "#include ". * src/straycats.c: Likewise. * src/ult_src.c: Likewise. 2014-09-12 Colin Watson 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): Remove. (btree_flopen): Expand B_FLAGS macro.

(Example database): Update example output. * NEWS: Document this. 2014-09-10 Colin Watson Move database mtime out of the database into file metadata This makes the database reproducible between installations, as long as the underlying database has predictable behaviour and the set of installed manual pages (including their timestamps) remains identical. As a bonus, we now use high-precision times in several places. Fixes Debian bug #760895. * gnulib: Import futimens and timespec modules. * libdb/db_btree.c (btree_get_time, btree_set_time): New functions. * libdb/db_gdbm.c (man_gdbm_get_time, man_gdbm_set_time): New functions. * libdb/db_ndbm.c (ndbm_get_time, ndbm_set_time): New functions. * libdb/mydbm.h (man_gdbm_get_time, man_gdbm_set_time, ndbm_get_time, ndbm_set_time, btree_get_time, btree_set_time): Add prototypes.

(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 $mtime$.

Switch to variants of the futimens/utimensat family instead, via Gnulib. Use higher-precision times for cat pages. * gnulib: Import stat-time and utimens modules. * src/man.c (man_modtime): Change type to struct timespec. (commit_tmp_cat): Use utimens rather than utime. (display): Store a higher-precision modification timestamp for man_file. 2014-09-09 Colin Watson catman: Honour program name transformations * src/catman.c (parse_for_sec): Execute MAN rather than "man". 2014-09-08 Colin Watson * man/po4a/po/da.po: Fix po4a syntax error. 2014-09-08 Colin Watson Various autotools upgrades * aclocal.m4: Upgrade to pkg-config 0.28. * build-aux/config.guess: Upgrade to 2014-03-23. * build-aux/config.sub: Upgrade to 2014-05-01. * build-aux/ltmain.sh: Upgrade to Libtool 2.4.2-1.10 (from Debian). 2014-08-30 Joe Hansen * man/po4a/po/da.po: Update from Translation Project. 2014-08-12 Arif E.
