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. (init_html_pager): Only define if `TROFF_IS_GROFF` is defined. (format_display): Mark `man_file` as unused if `TROFF_IS_GROFF` is not defined. * configure.ac: Substitute `troff_is_groff`. * src/tests/Makefile.am (TESTS_ENVIRONMENT): Export `troff_is_groff`. * src/tests/man-language-specific-requests: Adjust expected language-specific requests if `troff_is_groff` is not `yes`. * NEWS.md: Document this. 2022-11-29 Seong-ho Cho Update Korean manual page translation * man/po4a/po/ko.po: Update from Translation Project. 2022-11-28 Yuri Kozlov Update Russian manual page translation * man/po4a/po/ru.po: Update from Translation Project. 2022-11-15 Colin Watson Release man-db 2.11.1 2022-11-15 Colin Watson Tweak README for better readability * README.md: Add blank line for improved Markdown rendering. 2022-11-14 Colin Watson web: Fix man.png width/height * web/index.html: Update width and height for man.png. 2022-11-14 Colin Watson web: Update man(1) image * web/man.png: Replace with a fresh screenshot. 2022-11-14 Colin Watson Link to project home page * README.md: Add home page link (https://man-db.gitlab.io/man-db/). 2022-11-14 Colin Watson Add GitLab Pages site * .gitlab-ci.yml (stages): Add deploy. (pages): New job. * web/development.html, web/index.html, web/man.png, web/standard.css, web/white.css: New files. 2022-11-14 Colin Watson Transfer Git repository to new group * README.md, docs/HACKING.md, man/man1/apropos.man1, man/man1/lexgrog.man1, man/man1/man-recode.man1, man/man1/man.man1, man/man1/manconv.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: Change GitLab URL to https://gitlab.com/man-db/man-db. * NEWS.md: Document this. 2022-11-12 Colin Watson Remove unused include * src/manconv_client.c: Remove unused `#include "idpriv.h"`. 2022-11-05 Colin Watson Fix distribution of Korean manual page translation Accidentally omitted from 8f12d39bbb6748a1257358269028ef919f9c92e6. * man/Makefile.am (DIST_SUBDIRS): Add ko. 2022-11-05 Colin Watson Replace $ in page names rather than trying to escape it Jakub Wilk points out in Debian bug #1021951 that attempting to use the `--use-backslash` option has a number of complications. Just replace dollar signs with question marks instead. * include/manconfig.h (LESS_OPTS): Revert addition of `--use-backslash`. * src/man.c: Replace `$` characters with `?` rather than trying to escape them. * NEWS.md: Document this. 2022-11-05 Colin Watson Add Korean manual page translation * man/po4a/po/ko.po: New from Translation Project (thanks, Seong-ho Cho). * configure.ac (AC_CONFIG_FILES): Add man/ko/Makefile. * man/LINGUAS.po4a: Add ko. * man/Makefile.am (DIST_SUBDIRS): Add ko. * man/ko/Makefile.am, man/ko/translator.add: New files. * man/po4a/Makefile.am (POFILES): Add po/ko.po. * man/po4a/po4a.cfg (po4a_langs): Add ko. * man/THANKS: Update translator credit. * .gitignore: Add man/ko/man1, man/ko/man5, and man/ko/man8. 2022-10-28 Seong-ho Cho Add Korean translation * po/ko.po: New from Translation Project. * po/LINGUAS: Add ko. * man/THANKS: Add translator credit. 2022-10-28 Sebastian Rasmussen Update Swedish manual page translation * man/po4a/po/sv.po: Update from Translation Project. 2022-10-18 Colin Watson zsoelim_open_file: Fix use of uninitialized value In the case where `filename` has no directory part and does not contain a dot, we could reach the decision of whether to emit a "can't open %s" error message without initializing `decomp`. Noticed by `gcc -Og`. * src/zsoelim.l (zsoelim_open_file): Initialize `decomp` to NULL. 2022-10-18 Colin Watson 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. Update all callers. * lib/compression.h (comp_info): Update prototype. * lib/sandbox.c (seccomp_filter_unavailable): Change type to bool. Update all references.

Update all callers. * lib/util.h (remove_directory): Update prototype. * libdb/db_gdbm.c (opening): Change type to bool. Update all references. * libdb/db_store.c (compare_ids): Change `promote_links` parameter type to bool. Update all callers. * libdb/db_storage.h (compare_ids): Update prototype. * src/catman.c (parse_for_sec): Change `message` local variable type to bool. (check_access): Change return type to bool. (purge_whatis): Change `cat` parameter type to bool. Update all callers. (check_multi_key): Change return type to bool. * src/descriptions.c (parse_descriptions): Change `seen_base` local variable type to bool. * src/globbing.c (look_for_file): Change `cat` parameter type to bool. Update all callers. * src/globbing.h (look_for_file): Update prototype. * src/lexgrog.l (fill_mode, waiting_for_quote): Change types to bool. Update all references. * src/man.c (skip, created_tmp_cat): Change types to bool. Update all references. (run_mandb): Change `create` parameter type to bool. Update all callers. (squeeze_blank_lines): Change `in_blank_line` and `got_blank_line` local variable types to bool. (display): Change `format` and `printed` local variable types to bool. (convert_name): Change `fsstnd` parameter type to bool. Update all callers. (add_candidate): Change `dupcand` local variable type to bool. (main): Change `maybe_section` local variable type to bool. * src/manp.c (add_sections): Change `user` parameter type to bool. Update all callers. (add_def): Likewise. (add_mandb_map): Likewise. (add_to_dirlist): Likewise. (read_config_file): Change `done` local variable type to bool. (get_manpath_from_path): Change `mandatory` parameter type to bool. Update all callers. * src/manp.h (get_manpath_from_path): Update prototype. * src/whatis.c (do_apropos): Change `matched` local variable type to bool. * src/zsoelim.l (no_newline): Change type to bool. Update all references. (zsoelim_open_file): Change return type to true. * src/zsoelim.h (zsoelim_open_file): Update prototype. 2022-10-07 Colin Watson Remove unused variable * src/man.c (found_a_stray): Remove; it was set but no longer used. (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. However, the compiler probably had a hard time proving that, so the use-after-free warning issued by recent versions of GCC seems fair enough. * src/mandb.c (cleanup): Don't free dbpaths. (process_manpath): Free it here instead, after calling pop_cleanup. 2022-08-11 Colin Watson Make CATWIDTH override MINCATWIDTH/MAXCATWIDTH Otherwise setting `CATWIDTH` to something larger than 80 confusingly doesn't work unless you also set `MAXCATWIDTH`. Fixes https://gitlab.com/cjwatson/man-db/-/issues/9. * src/man.c (add_roff_line_length): Skip terminal width range check if `cat_width` is set. * man/man5/manpath.man5 (FORMAT): Remove note that `CATWIDTH` should be within the range set by `MINCATWIDTH` and `MAXCATWIDTH`, and instead say that it overrides them. * NEWS.md: Document this. 2022-07-22 Colin Watson Add more case variants of localized versions of NAME * src/lexgrog.l (bg_name, lt_name, ru_name, sr_name, srlatin_name, tr_name, uk_name, vi_name): Add more case variants. * NEWS.md: Document this. 2022-07-18 Colin Watson Update pre-commit hooks * .pre-commit-config.yaml (pre-commit-hooks): Update to v4.3.0. 2022-07-18 Colin Watson Update to Gnulib 20220717 Fixes https://gitlab.com/cjwatson/man-db/-/issues/6. * bootstrap: Sync to Gnulib df336dc1ae60d8ad9f452f2234951133fe617bb0. * bootstrap.conf (GNULIB_REVISION): Set to df336dc1ae60d8ad9f452f2234951133fe617bb0. * NEWS.md: Document build fix. 2022-07-15 Colin Watson Merge branch 'drop-lsm' into 'main' Drop LSM file See merge request cjwatson/man-db!4 2022-07-13 Pino Toscano Drop LSM file The LSM format is a very old format for software, and it is dead for many years already. Since keeping the .lsm up-to-date is basically not much of use, simply drop it altogether. * docs/Makefile.am (dist_noinst_DATA): Remove man-db.lsm. * docs/HACKING.md: Stop mentioning man-db.lsm. * docs/man-db.lsm: Remove file. 2022-07-05 Stéphane Aulery Update French manual page translation * man/po4a/po/fr.po: Update from Translation Project. 2022-06-02 Joe Hansen Update Danish translation * po/da.po: Update from Translation Project. 2022-05-18 Colin Watson Cache filters alongside whatis information `mandb` needs to cache filters together with whatis information, as otherwise pages were incorrectly recorded with no filters if `mandb` happened to use cached whatis information for them rather than reading it from scratch. * src/check_mandirs.c (struct whatis): Add filters. (whatis_free): Free whatis->filters. (test_manfile): Store and use whatis->filters. * NEWS.md: Document this. 2022-04-27 Andika Triwidada Update Indonesian translation * po/id.po: Update from Translation Project. * man/THANKS: Add translator credit. 2022-04-23 Colin Watson Stop GitLab from getting confused about licences GitLab uses https://github.com/licensee/licensee to detect the project's licence, and if that finds multiple matching files then it throws up its hands and refuses to make a licence assertion, with no apparent way to override it. To avoid this problem, move the secondary licence files (those that apply only to some files, rather than to the project as a whole) back into a subdirectory, so that `licensee` doesn't notice them. * COPYING.GPLv2: Move to ... * docs/COPYING.GPLv2: ... here. Update all references. * COPYING.LIB: Move to ... * docs/COPYING.LIB: ... here. Update all references. * Makefile.am (dist_noinst_DATA): Remove COPYING.GPLv2. * docs/Makefile.am (dist_noinst_DATA): Add COPYING.GPLv2 and COPYING.LIB. 2022-04-23 Colin Watson Clarify effective GPLv3 licensing While man-db's own files are individually licensed under GPLv2 (or in a few cases LGPLv2.1), the project as a whole is effectively GPLv3 due to Gnulib. This was already explained in README.md, but make it a bit clearer by having the top-level COPYING file be a copy of GPLv3. * COPYING: Move to ... * COPYING.GPLv2: ... here. * COPYING: New file. * Makefile.am (dist_noinst_DATA): Add COPYING.GPLv2. * lib/README, man/it/man1/apropos.man1, man/it/man1/man.man1, man/it/man1/manpath.man1, man/it/man1/whatis.man1, man/it/man1/zsoelim.man1, man/it/man5/manpath.man5, man/it/man8/accessdb.man8, man/it/man8/catman.man8, man/it/man8/mandb.man8, man/man1/apropos.man1, man/man1/lexgrog.man1, man/man1/man-recode.man1, man/man1/man.man1, man/man1/manconv.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, manual/comp.me, manual/db.me, manual/files.me, manual/format.me, manual/glossary.me, manual/intro.me, manual/leader.me, manual/man_db.me, manual/misc.me, manual/sec.me: Refer to COPYING.GPLv2 rather than COPYING. 2022-04-23 Colin Watson Update pre-commit hooks * .pre-commit-config.yaml (pre-commit-hooks): Update to v4.2.0. 2022-04-17 Emir SARI Update Turkish manual page translation * man/po4a/po/tr.po: Update from Translation Project. * man/THANKS: Update translator credit. 2022-04-16 Colin Watson Recognize another Turkish translation of NAME Emir SARI reports that "AD" is the de facto standard technical terminology for "NAME" in Turkish, rather than "İSİM" which sounds slightly colloquial. Recognize it as well. * src/lexgrog.l (tr_name): Add "AD". 2022-04-12 Emir SARI Update Turkish translation * po/tr.po: Update from Translation Project. * man/THANKS: Add translator credit. 2022-03-17 Colin Watson Release man-db 2.10.2 NEWS.md: Fix typo for 2.7.6 2022-03-08 Colin Watson pre-commit: Avoid need for multiple shellcheck runs * .shellcheckrc: Set `external-sources=true`. * src/tests/lexgrog-backslash-dash-rhs, src/tests/lexgrog-basic, src/tests/lexgrog-multiple-whatis, src/tests/man-deleted-directory, src/tests/man-exact-section-matches, src/tests/man-executable-page-on-path, src/tests/man-invalid-db-entry, src/tests/man-language-specific-requests, src/tests/man-mandatory-manpath, src/tests/man-missing-locales, src/tests/man-override-dir, src/tests/man-recode-in-place, src/tests/man-recode-suffix, src/tests/man-so-links-same-section, src/tests/man-suffixed-extension, src/tests/man-symlinks-with-matching-names, src/tests/manconv-coding-tags, src/tests/manconv-guess-from-encoding, src/tests/manconv-incomplete-char-at-eof, src/tests/manconv-odd-combinations, src/tests/mandb-basic, src/tests/mandb-bogus-symlink, src/tests/mandb-cachedir-tag, src/tests/mandb-empty-page, src/tests/mandb-purge-updates-timestamp, src/tests/mandb-regular-file-symlink-changes, src/tests/mandb-symlink-beats-whatis-ref, src/tests/mandb-symlink-target-timestamp, src/tests/mandb-whatis-broken-link-changes, src/tests/whatis-path-to-executable, src/tests/zsoelim-so-includes: Add `shellcheck source-path=SCRIPTDIR` directive before sourcing testlib.sh. * .pre-commit-config.yaml: Consolidate the two shellcheck hooks into one. 2022-03-08 Colin Watson pre-commit: Add shellcheck * .pre-commit-config.yaml: Add shellcheck. We need separate hooks for `src/tests/` and for everything else, since shellcheck needs a `-P` option to correctly handle sourced files in `src/tests/`. * .shellcheckrc: New file. 2022-03-08 Colin Watson Refactor use of cd in shell scripts shellcheck warns about unchecked uses of `cd` (SC2164). Either check it or refactor to avoid changing directory. * src/tests/man-deleted-directory: Check `cd` call. * src/tests/man-suffixed-extension: Avoid changing directory. * tools/mkcatdirs: Likewise. 2022-03-08 Colin Watson mkcatdirs: Skip nonexistent man directories * tools/mkcatdirs: `manpath -qg` may return man directories that are mentioned in the configuration file but that don't exist on the filesystem. Skip these. 2022-03-08 Colin Watson mkcatdirs: Refactor using install(1) I'm not sure this script is widely-used, but it might as well work. It previously relied on `mkinstalldirs`, which is a build tool not typically installed on end-user systems. * tools/mkcatdirs: Refactor cat directory creation using install(1). 2022-03-08 Colin Watson Apply various minor shell syntax improvements * manual/print-options: Explicitly set `LANGUAGE=''` rather than `LANGUAGE=`, pacifying shellcheck SC1007 which notes that this construction might otherwise be misread. * src/tests/manconv-odd-combinations: Use `printf %b` to pacify shellcheck SC2059. * src/tests/testlib.sh: Tell shellcheck which shell syntax to assume, since this file has no `#!` line. (run): Disable shellcheck SC2154; `abs_top_builddir` is always set by the test runner. (report): Remove unnecessary `$` before variable in arithmetic context. (tools/checkman): Use `$(...)` for command substitution. Quote variables properly where possible, and ignore shellcheck SC2068 in a couple of other places. 2022-03-07 Colin Watson tests: Pacify shellcheck SC2188 The previous construction resulted in: SC2188 (warning): This redirection doesn't have a command. Move to its command (or use 'true' as no-op). * src/tests/man-mandatory-manpath, src/tests/testlib.sh: Avoid redirections without a command. 2022-03-07 Colin Watson tests: Make pass/fail reporting more shellcheck-friendly * src/tests/testlib.sh (report): New function, similar to expect_pass but taking an exit code rather than a command string to evaluate. (expect_pass): Remove.

Apply it only when all paths have been gathered instead. Also look for override dir when sorting candidates. Fixes src/tests/man-override-dir failing when --with-override-dir=od is passed to ./configure. [cjwatson: Refactored candidate comparison to use a strcmp-style function, and simplified the addition of override directories a little more.] * src/man.c (compare_override_dir): New function. (compare_candidates): Compare override directory status between comparing section extensions and comparing locale elements. * src/manp.c (insert_override_dir): Remove. (get_manpath_from_path, add_man_subdirs): Remove calls to insert_override_dir. (create_pathlist): Add OVERRIDE_DIR at the canonicalization stage instead. * NEWS.md: Document this. Reported-by: Nikola Forró Tested-by: Nikola Forró 2022-03-06 Colin Watson Update to Gnulib 20220301 In line with Gnulib, we now require Automake 1.14. * bootstrap.conf (GNULIB_REVISION): Set to 8c4f4d7a3c28f88b64fce2fb1d0dc0e570d1a482.

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.

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.

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.

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.

If directive is non-NULL by the time these are used then they're always initialized, but cppcheck didn't manage to spot that. 2022-01-16 Colin Watson Update to Gnulib 20220116 * bootstrap: Sync to Gnulib 1eae0f7ea3c220d054025f2c9211700665f9f4a0. * bootstrap.conf (GNULIB_REVISION): Set to 1eae0f7ea3c220d054025f2c9211700665f9f4a0. 2022-01-16 Colin Watson Move some more declarations out of manconfig.h Header includes should be in the same translation unit as the code that uses them rather than being ambient across the whole project. * include/manconfig.h: Remove obsolete header comment about program paths. * include/manconfig.h: Remove includes of "xvasprintf.h", , "xalloc.h", and "xstrndup.h", as well as "struct pipeline" declaration. Update all files that relied on these to include/declare them directly instead as needed. * include/manconfig.h (MAN_DB, mkdbname): Move to ... * libdb/mydbm.h: ... here. 2022-01-16 Colin Watson Move appendstr out of manconfig.h * include/manconfig.h (appendstr): Move to ... * lib/appendstr.h: ... here (new file). * lib/Makefile.am (libman_la_SOURCES): Add appendstr.h. * lib/README: Update file names. * lib/appendstr.c, libdb/db_delete.c, src/catman.c, src/check_mandirs.c, src/compression.c, src/filenames.c, src/globbing.c, src/man.c, src/manconv_client.c, src/manconv_main.c, src/manp.c, src/straycats.c, src/whatis.c, src/zsoelim.l: Include appendstr.h. 2022-01-16 Colin Watson Move debug-related declarations out of manconfig.h * include/manconfig.h (debug_level, init_debug, debug, debug_error): Move to ... * lib/debug.h: ... here (new file). * lib/Makefile.am (libman_la_SOURCES): Add debug.h. * lib/README: Update file names. * lib/debug.c, lib/encodings.c, lib/sandbox.c, lib/security.c, lib/util.c, libdb/db_btree.c, libdb/db_delete.c, libdb/db_gdbm.c, libdb/db_lookup.c, libdb/db_store.c, libdb/db_ver.c, src/accessdb.c, src/catman.c, src/check_mandirs.c, src/descriptions.c, src/descriptions_store.c, src/filenames.c, src/globbing.c, src/globbing_test.c, src/lexgrog_test.c, src/man-recode.c, src/man.c, src/manconv.c, src/manconv_main.c, src/mandb.c, src/manp.c, src/manpath.c, src/straycats.c, src/ult_src.c, src/whatis.c, src/zsoelim.l, src/zsoelim_main.c: Include debug.h. 2022-01-16 Colin Watson Move create_tempdir out of manconfig.h * include/manconfig.h (create_tempdir): Move to ... * lib/tempfile.h: ... here (new file). * lib/Makefile.am (libman_la_SOURCES): Add tempfile.h. * lib/tempfile.c, src/man.c: Include tempfile.h. 2022-01-16 Colin Watson Move util.c-related declarations out of manconfig.h * include/manconfig.h (is_changed, is_directory, escape_shell, remove_directory, trim_spaces, lang_dir, init_locale): Move to ... * lib/util.h: ... here (new file). * lib/Makefile.am (libman_la_SOURCES): Add util.h. * lib/util.c, src/accessdb.c, src/catman.c, src/check_mandirs.c, src/descriptions.c, src/globbing.c, src/globbing_test.c, src/lexgrog.l, src/lexgrog_test.c, src/man-recode.c, src/man.c, src/manconv_main.c, src/mandb.c, src/manp.c, src/manpath.c, src/straycats.c, src/whatis.c, src/zsoelim_main.c: Include util.h. 2022-01-16 Colin Watson Move comp_info and comp_file out of manconfig.h * include/manconfig.h (comp_info, comp_file): Move to ... * src/compression.h: ... here (new file). * src/Makefile.am (lexgrog_SOURCES, man_SOURCES, man_recode_SOURCES, mandb_SOURCES): Add compression.h. * src/compression.c, src/filenames.c, src/man-recode.c, src/man.c, src/straycats.c, src/ult_src.c: Include compression.h. 2022-01-16 Colin Watson Move straycats out of manconfig.h * include/manconfig.h (straycats): Move to ... * src/straycats.h: ... here (new file). * src/Makefile.am (mandb_SOURCES): Add straycats.h. * src/mandb.c, src/straycats.c: Include straycats.h. 2022-01-16 Colin Watson Use lexgrog type definitions consistently * include/manconfig.h (MANPAGE, CATPAGE): Move to ... * src/lexgrog.h (MANPAGE, CATPAGE): ... here. * src/lexgrog.l (find_name, find_name_decompressed): Compare p_lg->type against CATPAGE rather than testing its truth value. * src/lexgrog_test.c (main): Set type to MANPAGE/CATPAGE rather than 0/1. 2022-01-16 Colin Watson Update translation files * po/man-db.pot, po/*.po: Update. 2022-01-16 Colin Watson Fix build system following changes to include/*.h * Makefile.am (noinst_HEADERS): Add include/comp_src.h and include/manconfig.h. * lib/Makefile.am (libman_la_CPPFLAGS): Replace -I$(top_builddir)/include with -I$(top_srcdir)/include. * libdb/Makefile.am (libmandb_la_CPPFLAGS): Likewise. * src/Makefile.am (AM_CPPFLAGS): Likewise. * src/tests/Makefile.am (AM_CPPFLAGS): Likewise. 2022-01-16 Colin Watson Remove Checker support The GNU Checker package was last released in 2005, and its web page (https://www.gnu.org/software/checker/) says that it has been decommissioned in favour of Valgrind. * include/manconfig.h (chkr_garbage_detector): Remove. * src/man.c (main): Remove call to chkr_garbage_detector. * src/mandb.c (main): Likewise. * src/whatis.c (search): Likewise. 2022-01-16 Colin Watson Remove obsolete include/README * include/README: Remove; it claimed that this directory contains files created by configure, which is no longer true, and it said nothing else useful. * Makefile.am (dist_noinst_DATA): Remove include/README. 2022-01-16 Colin Watson Stop generating include/*.h from configure This was inconvenient when making changes to those central header files. All `configure`-generated preprocessor symbols are now in `config.h`. * configure.ac: Define various PROG_* symbols. Remove AC_SUBST calls for compressors and decompressors. (AC_CONFIG_FILES): Remove include/comp_src.h and include/manconfig.h. * m4/man-arg-override-dir.m4: Define OVERRIDE_DIR symbol. * include/manconfig.h.in: Rename to ... * include/manconfig.h: ... this. Remove PROG_*, OVERRIDE_DIR, and COMPRESS_EXT definitions. * include/comp_src.h.in: Rename to ... * include/comp_src.h: ... this. * README.md: Update references to include/manconfig.h. * .gitignore: Remove include/*.h. 2022-01-16 Colin Watson Rename program preprocessor symbols to PROG_* This is mainly in order to avoid potential confusion with `PIC` (defined when building position-independent code), but I renamed all these variables for consistency. * include/manconfig.h.in (PAGER, CAT, WEB_BROWSER, TR, GREP, TROFF, NROFF, EQN, NEQN, TBL, COL, VGRIND, REFER, GRAP, PIC, COMPRESSOR, GUNZIP, UNCOMPRESS, BUNZIP2, UNLZMA, UNXZ, LZIP, UNZSTD): Rename to ... (PROG_PAGER, PROG_CAT, PROG_BROWSER, PROG_TR, PROG_GREP, PROG_TROFF, PROG_NROFF, PROG_EQN, PROG_NEQN, PROG_TBL, PROG_COL, PROG_VGRIND, PROG_REFER, PROG_GRAP, PROG_PIC, PROG_COMPRESSOR, PROG_GUNZIP, PROG_UNCOMPRESS, PROG_BUNZIP2, PROG_UNLZMA, PROG_UNXZ, PROG_LZIP, PROG_UNZSTD): ... these (respectively). Update all references. 2022-01-16 Colin Watson Move lexgrog-related bits out of manconfig.h It's generally cleaner for things like this to be in a dedicated header file. * include/manconfig.h.in (struct lexgrog, find_name, find_name_decompressed): Move to ... * src/lexgrog.h: ... here (new file). Simplify declarations slightly. * include/manconfig.h.in (lexgrog filter enum): Move to ... * src/lexgrog.l: ... here. * src/Makefile.am (lexgrog_SOURCES, mandb_SOURCES): Add lexgrog.h. * src/check_mandirs.c, src/lexgrog.l, src/lexgrog_test.c, src/straycats.c: Include lexgrog.h. 2022-01-16 Martin man-db.timer: Use RandomizedDelaySec Avoids congesting resources, otherwise this runs daily at 12:00 and 00:00 https://www.freedesktop.org/software/systemd/man/systemd.timer.html 2022-01-09 Colin Watson Recognize Arabic and Persian translations of NAME * src/lexgrog.l (ar_name, fa_name): Add.

Pointed out by Steinar H. Gunderson in https://bugs.debian.org/1003089. * lib/sandbox.c (make_seccomp_filter): Return NULL early if can_load_seccomp returns false. (_sandbox_load): Return early if the relevant context is NULL. (sandbox_free): Only call seccomp_release if the relevant context is non-NULL. 2022-01-03 Colin Watson Indicate that merge requests are preferred * docs/HACKING.md (Sending patches): Describe merge request workflow and indicate that it is preferred. 2022-01-03 Colin Watson Reformat hacking documentation as Markdown * docs/HACKING: Move to ... * docs/HACKING.md: ... here. Reformat as Markdown. * docs/Makefile.am (dist_noinst_DATA): Replace HACKING with HACKING.md. 2022-01-03 Colin Watson Add release automation When a tag is pushed to GitLab, upload the bootstrapped source tarball to the package registry, and create a release in GitLab associated with the tag. * .gitlab-ci.yml (stages): Remove test, since it had no jobs. Add upload and release. (build-distcheck:script): Configure with --enable-maintainer-mode, to ensure that flex-generated scanners are fresh. (upload, release): New jobs. * release.sh: Remove. GitLab CI handles building releases now. * Makefile.am (EXTRA_DIST): Remove release.sh. * docs/HACKING: Update for GitLab-based release process. 2022-01-03 Colin Watson Reformat release notes as Markdown * NEWS: Move to ... * NEWS.md: ... here. Reformat as Markdown. * Makefile.am (dist_noinst_DATA): Remove NEWS; Automake automatically includes this file (or NEWS.md) in the distribution without help. * README.md, docs/HACKING: Refer to NEWS.md instead of NEWS. 2022-01-02 Colin Watson Remove superfluous quotes * Makefile.am (gen_start_date): Remove superfluous quotes. 2022-01-02 Colin Watson Add build-distcheck CI artifact This should eventually allow publishing release tarballs built by a CI process rather than on my laptop. * .gitlab-ci.yml (variables): Set GIT_DEPTH to 0; we need full history in order to build the ChangeLog file. (bootstrap:before_script): Add wget, needed to fetch Gnulib PO files. (build-distcheck:before_script): Add git, needed by gitlog-to-changelog. (build-distcheck:artifacts): Add bootstrapped/*.tar.xz. 2022-01-02 Colin Watson 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.

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. (display): In gxditview mode, call the ordinary "display formatted page" logic, without saving a cat page. 2020-05-31 Colin Watson * NEWS: Move misplaced entry to "Fixes". 2020-05-31 Colin Watson Fix document font size for -X75-12 and -X100-12 Reported by Konrad Schwarz. * src/man.c (make_roff_command): Add the "-rS12" argument if the argument to -X contains "-12". * NEWS: Document this. 2020-05-17 Stéphane Aulery Update French manual page translation * man/po4a/po/fr.po: Update from Translation Project. * man/THANKS: Update translator credit. 2020-04-12 Mario Blättermann Update German manual page translation Fixes Debian bug #955320. * man/po4a/po/de.po: Update from Translation Project. 2020-04-12 Colin Watson NEWS: Remove superfluous ")" 2020-04-03 Boyuan Yang <073plan@gmail.com> Update Simplified Chinese manual page translation * man/po4a/po/zh_CN.po: Update from Translation Project. 2020-04-02 Мирослав Николић Update Serbian translation * po/sr.po: Update from Translation Project. 2020-03-29 Colin Watson Add bug tracker link to manual pages Fixes Savannah bug #58039. * man/man1/apropos.man1 (BUGS), man/man1/lexgrog.man1 (BUGS), man/man1/man-recode.man1 (BUGS), man/man1/man.man1 (BUGS), man/man1/manconv.man1 (BUGS), man/man1/manpath.man1 (BUGS), man/man1/whatis.man1 (BUGS), man/man1/zsoelim.man1 (BUGS), man/man8/accessdb.man8 (BUGS), man/man8/catman.man8 (BUGS), man/man8/mandb.man8 (BUGS): New section, containing a link to the bug tracker. * man/man5/manpath.man5 (BUGS): Add a link to the bug tracker. * NEWS: Document this. 2020-03-28 Bjarni Ingi Gislason man/man8/*: Fix misuse of two-fonts macros Correct the misuse of a two-fonts macro, which function is to 1) use the first font for each odd numbered argument and the second font for all others. 2) join (output) the arguments without an intervening space.

Remove extra newline before "using %s as pager". * src/manp.c (describe_flag, print_list): Remove: everything that adds items to this list already emits a more human-friendly debugging message. Remove caller of print_list. (add_sections): Squash debugging output onto one line, and indent it by two spaces. (add_def, add_manpath_map, add_mandb_map, add_mandatory): Indent debugging output by two spaces. (read_config_file): Remove extra newline after "From the config file %s:". (get_manpath_from_path): Remove extra newlines before "path directory %s" and "adding mandatory man directories". (add_expanded_dir_to_list): Remove noisy "%s is already in the manpath" debugging output. Indent "adding %s to manpath" by two spaces. (add_man_subdirs): Remove noisy "and doesn't have ../man, man, ../share/man, or share/man subdirectories" debugging output. 2019-09-08 Colin Watson 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.

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. (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.

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

(bootstrap_post_import_hook): Merge temporary gl/ref-po directory into gl/po. 2018-07-27 Colin Watson Upgrade to Gnulib 20180726 * bootstrap: Sync to Gnulib 900ca5c0b092e50f9f17329feea3fbfe2b6e2139. * bootstrap.conf (GNULIB_REVISION): Set to 900ca5c0b092e50f9f17329feea3fbfe2b6e2139. 2018-07-18 Colin Watson Distribute man/es/translator.add * man/es/Makefile.am (EXTRA_DIST): Add translator.add. 2018-07-16 Colin Watson sandbox: Improve ESET compatibility further * lib/sandbox.c (make_seccomp_filter): If libesets_pac.so is preloaded, then allow msgset (second argument 0) and msgsnd. * NEWS: Document this. 2018-07-15 Colin Watson sandbox: Allow some shared memory operations These were previously only allowed when ESET File Security is in use, but the Astrill VPN seems to require something similar, there are doubtless other such preload hacks, and they're relatively harmless. * lib/sandbox.c (make_seccomp_filter): Allow shmat (third argument SHM_RDONLY), shmctl (second argument IPC_STAT), shmdt, and shmget regardless of preloads. * NEWS: Document this. 2018-06-08 Colin Watson Check for external formatter in correct directory Check for mandb_nfmt and mandb_tfmt in the manual page hierarchy as documented, not in the current directory. This was broken by the working-directory-handling changes in 2.8.3. Reported by Josh Triplett. Fixes Debian bug #901007. * src/man.c (NFMT_PROG, TFMT_PROG): Remove leading "./". (make_roff_command): Refactor confusing #ifdef forest. Prefix dir to TFMT_PROG/NFMT_PROG rather than looking in the current directory. Don't look for an external formatter at all if dir is NULL. * NEWS: Document this. 2018-06-08 Colin Watson Define an access(2) wrapper with clearer semantics As usual for system calls, access(2) returns zero on success. However, I generally think of it as "can we access this file in this way", where boolean semantics would be more convenient, and find it too easy to invert logic by accident when using the system call directly. Define a CAN_ACCESS wrapper with boolean semantics. * include/manconfig.h.in (CAN_ACCESS): New macro. * lib/tempfile.c (path_search): Use CAN_ACCESS. * src/catman.c (check_access): Likewise. * src/filenames.c (make_filename): Likewise. * src/man.c (make_roff_command, display): Likewise. * src/ult_src.c (find_include): Likewise. * src/whatis.c (use_grep): Likewise. 2018-06-07 Felipe Castro Update Esperanto translation * po/eo.po: Update from Translation Project. 2018-06-01 Francisco Javier F.

(GNULIB_REVISION): Set to 90f289f249a266b1afb9c63e182f5d979d17df5f. (gnulib_modules): Replace gettext with gettext-h. (gnulib_tool_option_extras): Remove --no-cache-modules (accidental leftover from earlier testing). (local_gl_dir): Set to 'gnulib-local' to avoid confusion with 'gl' as the local output directory. Remove 'rm -rf gl' hack, now superseded. (buildreq): Bump minimum autopoint and gettext versions to 0.18.3, matching previous change to configure.ac. * configure.ac (AM_PROG_AR, LT_INIT): Move below gl_EARLY. * patches/argp-domain.patch: Rebase. * src/tests/Makefile.am (TESTS_ENVIRONMENT): Remove use of @LOCALCHARSET_TESTS_ENVIRONMENT@, which is no longer needed by Gnulib. 2018-05-28 Colin Watson Switch to bootstrap We no longer keep autogenerated files in git. * .gitignore: Add **/Makefile, **/Makefile.in, /ABOUT-NLS, /aclocal.m4, /build-aux, /config.h.in, /configure, /gl, /gnulib, docs/INSTALL.autoconf, po/Makefile.in.in, po/Makevars, po/Rules-quot, po/boldquot.sed, po/en@boldquot.header, po/en@quot.header, po/insert-header.sin, po/quot.sed, and po/remove-potcdate.sin.

Unfortunately, the way this works in argp (separating the two sections using a '\v' character) means that this results in argp trying to translate the empty string, which produces gettext catalog headers. The easiest way to suppress this odd behaviour seems to be to use a help filter function, so do that. Reported by Rafael Fontenelle. * src/accessdb.c (help_filter): Return NULL for ARGP_KEY_HELP_PRE_DOC. * src/lexgrog_text.c (help_filter): New function.

Fixes Debian bug #894792. * gnulib/m4/gnulib-cache.m4 (gl_MODULES): Remove save-cwd. * src/man.c (make_display_command): Remove now-unnecessary code to run the pager in the original working directory. (chdir_commands): New function. (format_display): Change directory just for format_cmd and disp_cmd rather than in-process. (display): Change directory just for format_cmd rather than in-process.

Based on a patch by Paul Wise. Fixes Debian bug #892309. * lib/sandbox.c (make_seccomp_filter): Allow kill and tgkill unconditionally. (adjust_seccomp_filter): Remove. (_sandbox_load): Remove call to adjust_seccomp_filter. * NEWS: Document this. 2018-03-17 Colin Watson sandbox: Allow madvise Reported by Tobias Klausmann. * lib/sandbox.c (make_seccomp_filter): Allow madvise. * NEWS: Document this. 2018-03-02 Francisco Javier Serrador Update Spanish translation * po/es.po: Update from Translation Project. * man/THANKS: Add translator credit. 2018-02-28 Colin Watson * Version: 2.8.2. 2018-02-28 Colin Watson sandbox: Handle qemu-user returning EFAULT Fixes Debian bug #891109. * lib/sandbox.c (_sandbox_load): Interpret EFAULT from seccomp_load as meaning that seccomp is unavailable, since this can be returned by some versions of qemu-user. * NEWS: Document this. 2018-02-28 Colin Watson sandbox: Add some more ESET affordances * lib/sandbox.c (make_seccomp_filter): If libesets_pac.so is preloaded, then allow some shared memory calls and checking for the existence of other processes. 2018-02-25 Colin Watson sandbox: Work around snoopy Fixes Debian bug #890861. * lib/sandbox.c (search_ld_preload): Cache /etc/ld.so.preload contents between calls. (make_seccomp_filter): Allow some socket-related system calls if libsnoopy.so is preloaded. 2018-02-25 Colin Watson sandbox: Generalise libesets_pac.so check slightly * lib/sandbox.c (make_seccomp_filter): LD_PRELOAD or /etc/ld.so.preload can just contain "libesets_pac.so" without an explicit path, so make the search slightly more permissive. 2018-02-20 Colin Watson sandbox: Handle /etc/ld.so.preload At least ESET File Security may be configured using /etc/ld.so.preload rather than the LD_PRELOAD environment variable, so unfortunately we need to check that too. * lib/sandbox.c (search_ld_preload): New function, handling both LD_PRELOAD and /etc/ld.so.preload. (can_load_seccomp, make_seccomp_filter): Use search_ld_preload. 2018-02-19 Colin Watson sandbox: Work around ESET File Security This is a proprietary antivirus program, so this is only a best guess from strace output. The choices are to disable the sandbox entirely or to allow a few socket-related system calls if this antivirus program is detected, and the latter is probably slightly better. Reported by John Sivak. * lib/sandbox.c (make_seccomp_filter): If LD_PRELOAD contains the substring "/libesets_pac.so", then allow some socket-related system calls so that the preload wrapper can talk to its daemon. * NEWS: Document this. 2018-02-19 Colin Watson sandbox: Allow ioctl(fd, TIOCGWINSZ) Patch from the anonymous reporter of https://savannah.nongnu.org/bugs/?53183 (though I think is obvious for copyright purposes given knowledge of the failing system call). Fixes Savannah bug #53183 (maybe). * lib/sandbox.c (make_seccomp_filter): Allow ioctl(fd, TIOCGWINSZ). * NEWS: Document this. 2018-02-14 Colin Watson sandbox: Allow kill/tgkill for current process xz is multithreaded, so the threading library may need to use tgkill to pass signals between threads, for example when it receives SIGPIPE. Fixes Savannah bug #53143. * lib/sandbox.c (SC_ALLOW, SC_ALLOW_ARG_1, SC_ALLOW_ARG_2): Move macro definitions out of make_seccomp_filter. (adjust_seccomp_filter): New function.

The default is unchanged from before this patch. If no --with(out)-libseccomp has been given on the command line, the macro looks for presence of libseccomp and uses that if found. * m4/man-libseccomp.m4: Guard pkg-config test with a command-line option. 2018-02-07 Colin Watson * NEWS: Document changes since 2.8.0. 2018-02-07 Colin Watson Reduce number of MAN_OWNER ifdefs * lib/security.c (init_security, running_setuid): Define unconditionally, with stub behaviour if MAN_OWNER is undefined. * lib/security.h (get_man_owner): Only declare prototype if MAN_OWNER is defined. * src/check_mandirs.c (chown_if_possible) [!MAN_OWNER]: Mark path argument as unused. * src/lexgrog_test.c (main): Call init_security unconditionally. * src/man.c (main): Likewise. * src/manconv_client.c (manconv_pre_exec): Define unconditionally.

Use get_man_owner rather than equivalent inline code. * src/manp.c (get_def): Define unconditionally. * src/manp.h (get_def): Drop macro alternative. 2018-02-07 Colin Watson Fix manconv under seccomp when man is setuid We must drop privileges before loading the sandbox. Reported by Lars Wendler. * src/manconv_client.c (manconv_pre_exec): New function. (manconv_stdin): Move setuid hack to ... (add_manconv): ... here, now implemented using a custom pre-exec hook. We no longer have a fall-through if dropping privileges fails, since that's now harder to do and wasn't really necessary in the first place. 2018-02-07 Colin Watson Refactor do_system_drop_privs Now that we have pipecmd_pre_exec, this can be simplified quite a bit. * lib/security.c (drop_privs): New function. (do_system_drop_privs_child, do_system_drop_privs): Remove. * lib/security.h (drop_privs): Add prototype. (do_system_drop_privs): Remove prototype. * src/man.c (make_browser): Add drop_privs pre-exec hook to browser command. (format_display): Call browser using pipeline_run rather than do_system_drop_privs, since it now has a pre-exec hook to drop privileges. 2018-02-07 Colin Watson Refactor sandbox attachment to be more composable The sandbox interface now exposes the necessary load/free primitives, and callers use them directly with pipecmd_pre_exec.

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.

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.

(finish_up, do_chown, cleanup_sigsafe, cleanup, mandb): Take dbpaths argument. (process_manpath): Allocate dbpaths on the stack, zero it, and pass it to functions that need it. 2015-12-07 Colin Watson Remove lots of unnecessary inline qualifiers It's 2015. The compiler almost certainly knows better than we do. * lib/security.c (gripe_set_euid): Remove inline qualifier. * libdb/db_btree.c (btree_findkey): Likewise. * libdb/mydbm.h (gdbm_exists): Likewise. * src/catman.c (catman): Remove obsolete comment.

Thanks to Nikola Forró; fixes Fedora bug #1263930. * man/Rules.man: Declare dependency of $(MANS) on replace.sed separately rather than trying to do so in suffix rules. * NEWS: Document this. 2015-09-22 Colin Watson Fix crash in manpath deduplication * src/manp.c (create_pathlist): Handle NULL return from canonicalize_file_name. * NEWS: Document this. 2015-09-22 Colin Watson Upgrade config.guess/config.sub * build-aux/config.guess, build-aux/config.sub: Upgrade to 2015-08-20. 2015-09-21 Nikola Forró Fix typos in italian manpath man page 2015-09-16 zwpwjwtz Update Simplified Chinese manual page translation * man/po4a/po/zh_CN.po: Update from Translation Project. * man/THANKS: Add translator credit. 2015-09-09 Colin Watson * Version: 2.7.3. 2015-09-09 Colin Watson Pacify gcc -Wlogical-not-parentheses * src/man.c (find_cat_file): Add extra parentheses around logical-not on the LHS of a comparison. * lib/util.c (is_changed): Likewise in header comment. 2015-09-09 OGAWA Hirofumi Restore the ability to use 'man -a' noninteractively Fixes Debian bug #798094. * src/man.c (do_prompt): Return 0 immediately (i.e. view) if neither stdin nor stdout is a tty. * NEWS: Document this. 2015-09-09 Mike Frysinger Fix crash when current directory is unreadable Fixes Savannah bug #45861. * src/man.c (make_display_command): Check have_cwd before trying to use cwd. * NEWS: Document this. 2015-09-09 Colin Watson Document squeeze-blank-lines fix * NEWS: Document Rafael's squeeze-blank-lines fix. 2015-09-09 Colin Watson Fix use-after-free in ult_src Reported by Hanno Boeck. Fixes Savannah bug #45854. * src/ult_src.c (ult_src): Take a copy of base when recursing rather than passing it directly as the new name argument, since it may be freed by the recursive call. * NEWS: Document this. 2015-09-09 Colin Watson Remove unnecessary check before free * src/ult_src.c (ult_src): Don't check whether base is non-NULL before freeing it. 2015-08-30 Rafael Kitover Squeeze blank lines internally instead of pager -s Add a pipecmd in make_display_command to combine multiple blank lines in the output into one, which is what e.g. less -s does. Stop automatically appending -s to pager command in configure.

Fixes Fedora bug #1249377. * man/man1/man.man1 (EXAMPLES): "man -k" and "man -f" are equivalent to "apropos" and "whatis" respectively, not "apropos -r" and "whatis -r". * man/po4a/po/man-db-manpages.pot, man/po4a/po/*.po: Update; unfuzzy all translations. 2015-08-02 Lauri Nurmi * po/fi.po: Update from Translation Project. 2015-04-08 Colin Watson Allow using GDBM's NDBM compatibility layer This isn't very useful in practice since anyone using this could just use GDBM directly instead, but it's helpful for testing. * configure.ac: Check for gdbm-ndbm.h and libgdbm_compat. 2015-04-08 Colin Watson Clean up freeing of datum structures * libdb/mydbm.h (MYDBM_FREE): Remove. (MYDBM_FREE_DPTR): New macro.

(parse_for_sec): ... here. 2015-03-05 Colin Watson man: Avoid dubious use of freopen to reopen base streams freopen doesn't actually work properly when base streams have been closed (at least with glibc), and it seems better to simply refuse to operate in such a non-conforming environment. * src/man.c (check_standard_fds): New function. (main): Call it rather than using freopen. 2014-11-16 Colin Watson 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.

(format_display, main): Save current working directory using save_cwd rather than xgetcwd. (format_display, local_man_loop, main): Restore previous working directory using restore_cwd rather than chdir. * src/tests/man-10: New file. * src/tests/Makefile.am (TESTS_ENVIRONMENT): Insert the parent directory into $PATH using an absolute path rather than a relative one. Export abs_top_builddir rather than top_builddir. (ALL_TESTS): Add man-10. * src/tests/testlib.sh (init): Set abstmpdir. Adjust tests to use this where applicable. (run): Call libtool using an absolute path. (skip): Remove abstmpdir.

(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.

(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.
