The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + +1.1 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. Installers may use special +options at configuration time for changing the default behaviour. The +command: + + ./configure --disable-nls + +will _totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl' library +and will decide to use it. If not, you may have to to use the +`--with-libintl-prefix' option to tell `configure' where to look for it. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.2 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. If you happen to have the `LC_ALL' or some other +`LC_xxx' environment variables set, you should unset them before +setting `LANG', otherwise the setting of `LANG' will not have the +desired effect. Here `LL' is an ISO 639 two-letter language code, and +`CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.3 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `coordinator@translationproject.org' to +reach the coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.4 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of June +2010. The matrix shows, in regard of each package, for which languages +PO files have been submitted to translation coordination, with a +translation percentage of at least 50%. + + Ready PO files af am an

preceding matrix are higher than the number of +visible blocks let us expect. This is because a few extra PO files are +used for implementing regional variants of languages, or language +dialects. + + For a PO file in the matrix above to be effective, the package to +which it applies should also have been internationalized and +distributed as such by its maintainer. There might be an observable +lag between the mere existence a PO file and its wide availability in a +distribution. + + If June 2010 seems to be old, you may fetch a more recent copy of +this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date +matrix with full percentage details can be found at +`http://translationproject.org/extra/matrix.html'. + +1.5 Using `gettext' in new packages +=================================== + +If you are writing a freely available program and want to +internationalize it you are welcome to use GNU `gettext' in your +package. Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`coordinator@translationproject.org' to make the `.pot' files available +to the translation teams. + diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 0000000..65e7855 --- /dev/null +++ b/ChangeLog @@ -0,0 +1,5179 @@ +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 МироÑлав Ðиколић + + 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.

The original goal +of man-db was, as indicated by the name, to add database caching to manual +page searches. The increase in computer performance has considerably +outpaced the growth of manual page collections, so some people now ask what +the point is of using man-db rather than man. + +These days, the database is indeed not such an important difference between +man-db and man, but there are several other areas where man-db does a +significantly better job than man: + + * Internationalisation + + man uses the obsolete catgets system for translations of the messages + emitted by its programs, which cannot deal with the user using a + different output encoding (e.g. UTF-8) from that provided by the + translators. man-db uses gettext, which is more correct and robust. + + In order to support many cases of non-English manual pages, man requires + manual hardcoding of iconv pipelines (or similar) and *roff device names + in its configuration file, and cannot operate correctly in environments + involving a variety of encodings. man-db handles all this out of the + box. + + * Security and code quality + + Security matters because both man and man-db can be installed setuid to + a special user, and also because man is sometimes used in semi-trusted + or untrusted contexts, such as from CGI scripts. + + Both man and man-db spend a lot of time calling external programs, often + in pipelines. man does so by assembling strings which it then feeds to + the shell; this approach is nowadays well-known to be fragile and prone + to security vulnerabilities. man-db has been redesigned from top to + bottom to have safe and correct command execution, using a special + "libpipeline" library. + + * Performance + + Happily, dealing with manual pages is not normally a + performance-critical task these days; manual pages can normally be found + and rendered comfortably within expected interactive response times. + However, there are a few cases that are still more difficult, such as + 'man -K' to perform a full-text search on all manual pages. Neither man + nor man-db includes a proper full-text search engine, but there is + nevertheless a significant performance difference here: man-db performs + this search at least three times as quickly as man, and in some cases + much better than that. (On the test system, man took five minutes to + search all manual pages, severely degrading interactive performance of + the rest of the system for that time; man-db took around 40 seconds.) + + * Maintenance + + At the time of writing (February 2012), man-db has had ten full releases + since the start of 2008 with substantial feature work, while man has had + one release with a few minor changes. + +I have great respect for the people who maintain man, but as a project it +has fallen badly behind. Rather than continuing to struggle along with +complicated patch sets, those distributions that still use man would +probably be better off switching to man-db. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..8670d04 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,88 @@ +## Process this file with automake to produce Makefile.in +## +## Copyright (C) 1994, 1995 Graeme Wilford. +## Copyright (C) 2001, 2002, 2003, 2005, 2006, 2007, 2009, 2010, 2011, 2012 +## Colin Watson. +## +## This file is part of man-db. +## +## man-db is free software; you can redistribute it and/or modify it +## under the terms of the GNU General Public License as published by +## the Free Software Foundation; either version 2 of the License, or +## (at your option) any later version. +## +## man-db is distributed in the hope that it will be useful, but +## WITHOUT ANY WARRANTY; without even the implied warranty of +## MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

) form on its command + line, so for example "man 'chmod(2)'" is now the same as "man 2 + chmod". While this requires more quoting, it may also be more + convenient when copying and pasting cross-references to manual + pages. + + * manconv now guesses the input encoding based on the file name if + it is not explicitly specified. + + * There is a new "man-recode" program. It fulfils a purpose similar + to "man --recode", but has an interface designed for bulk + conversion and so can be much faster when used on a large number + of pages. + + Compatibility notes: + -------------------- + + * Remove the ability to undefine COMP_SRC at build-time to disable + reading compressed manual pages. This was always only a + micro-optimisation, and it wasn't worth the extra code complexity. + You can still configure without any compressors (either by not + having them available at build time, or by configuring with + "--with-gzip=" etc.) to achieve much the same practical effect, + although the test suite still requires at least gunzip. + +man-db 2.8.7 (26 August 2019) +============================= + +Major changes since man-db 2.8.6.1: + + Fixes: + ------ + + * Further workarounds for ESET File Security: allow sendmsg when it + is in use. + + * The seccomp sandbox now causes disallowed system calls to return + EPERM rather than raising SIGSYS, in the hope of being less + disruptive to preload hacks. + + * Make seccomp sandbox allow getrandom, used by Hardened Malloc. + + * man no longer saves cat pages if --no-hyphenation or + --no-justification is used. + + * Move decompression code out of libman. This should really fix a + link failure using the Darwin linker (unsuccessfully attempted in + 2.8.6), and possibly on other platforms too. + + * Pass the database file name around in function parameters, rather + than storing it in a global variable with an unresolved symbol + from libmandb. Like the previous item, this fixes a link failure + using the Darwin linker, and possibly on other platforms too. + + * Return database entries in sorted order when using NDBM. (This is + based on a similar fix to the GDBM backend in man-db 2.4.2.) + + Improvements: + ------------- + + * Recognise Esperanto, Tamil, and Ukrainian translations of the NAME + section. + +man-db 2.8.6.1 (5 August 2019) +============================== + +Major changes since man-db 2.8.6: + + Fixes: + ------ + + * Fix missing memory copies in ult_src that caused segfaults in + mandb. + +man-db 2.8.6 (3 August 2019) +============================ + +Major changes since man-db 2.8.5: + + Fixes: + ------ + + * If more than one of "../man", "man", "../share/man", and + "share/man" exist relative to a directory on $PATH, then all of + them are now added to the automatically-determined manpath; + previously, only the first was considered. + + * Remove arbitrary limit on manpath size. + + * The systemd database maintenance service now runs mandb with the + --quiet option, avoiding excess log messages. + + * Default to --without-systemdsystemunitdir and + --without-systemdtmpfilesdir on non-Linux systems. + + * Fix failure to link libman using the Darwin linker. + + * "apropos -w" now works when given a non-lower-case pattern. + + Improvements: + ------------- + + * Convert most list and hash table code to Gnulib's container types: + these are more flexible and normally more concise than home-grown + equivalents. + + * There is a new configure option --disable-manual, which causes the + man-db manual not to be built or installed. + +man-db 2.8.5 (5 January 2019) +============================= + +Major changes since man-db 2.8.4: + + Building man-db now requires Autoconf >= 2.63 and Automake >= + 1.11.2. + + Fixes: + ------ + + * Fix build with Berkeley DB. + + * Fail to configure if flex is needed but missing. + + * Fix the comment in the first line of the configuration file in the + case where configure was not given a --with-config-file option. + + * Fix several resource and memory leaks. + + * Fix handling of \- in the right-hand side of a NAME section. + + * Work around Microsoft's proprietary "System Center Endpoint + Protection" antivirus program in the seccomp sandbox. + + Improvements: + ------------- + + * Ship a systemd timer to perform daily database maintenance. + + * Allow disabling the installation of the systemd tmpfiles snippet + and the systemd timer by configuring with + --with-systemdtmpfilesdir=no and --with-systemdsystemunitdir=no + respectively. + +man-db 2.8.4 (27 July 2018) +=========================== + +Major changes since man-db 2.8.3: + + Fixes: + ------ + + * Rely on decompressors reading from their standard input rather + than redundantly passing them the input file on their command + line. This works better with downstream AppArmor confinement of + decompressors. + + * Fix invalid syntax in tmpfiles.d/man-db.conf when configured with + --disable-cache-owner. + + * Make seccomp sandbox allow sched_getaffinity, sometimes used by + xz. + + * 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. Note that this + change means that "man -l" will never use an external formatter + (which was never documented behaviour and was surely a bad idea). + + * Make seccomp sandbox allow some shared memory operations across + the board rather than just when ESET File Security is in use; the + Astrill VPN seems to require something similar, and there are + doubtless other such preload hacks. + + * Some versions of ESET File Security call msgget and msgsnd; if + this program is in use, then allow those. + +man-db 2.8.3 (5 April 2018) +=========================== + +Major changes since man-db 2.8.2: + + Fixes: + ------ + + * Make seccomp sandbox allow madvise, since that's used by lbzip2. + + * Make seccomp sandbox allow kill and tgkill outright, since groff + uses kill to pass on signals to its child processes. + + * Make seccomp sandbox allow sibling architectures on + x86/x86_64/x32, since people sometimes mix and match architectures + there for performance reasons. + + * Fix version check in locale macro loading to tolerate groff + release candidates. + + * man now only changes working directory in child processes, so + never fails due to being unable to change back to its original + working directory. + + * accessdb, apropos, and lexgrog no longer emit spurious gettext + headers in their --help output when localised. + +man-db 2.8.2 (28 February 2018) +=============================== + +Major changes since man-db 2.8.1: + + Fixes: + ------ + + * Make seccomp sandbox allow kill and tgkill when the signal is + directed at the current process or one of its threads; this is + needed by xz. + + * Make seccomp sandbox allow ioctl(fd, TIOCGWINSZ), since that's used + by musl. + + * Work around the proprietary "ESET File Security" antivirus program in + seccomp sandbox: if this is in use then we need to allow some + socket-related system calls. + + * Work around the "snoopy" execve() wrapper and logger in seccomp + sandbox: if this is in use then we need to allow some + socket-related system calls. + + * Interpret EFAULT from seccomp_load as meaning that seccomp is + unavailable, since this can be returned by some versions of + qemu-user. + +man-db 2.8.1 (9 February 2018) +============================== + +Major changes since man-db 2.8.0: + + Fixes: + ------ + + * Fix seccomp sandbox build on Linux/POWER. + + * Fix manconv execution under seccomp when man is installed setuid. + + * Make seccomp sandbox allow mremap (used by iconv, for example). + + Improvements: + ------------- + + * configure now has a --without-libseccomp option to disable the use + of seccomp even if the library is available. + +man-db 2.8.0 (4 February 2018) +============================== + +Major changes since man-db 2.7.6.1: + + Fixes: + ------ + + * Fix locale macro loading for Chinese to load the macro file + corresponding to just the language part of the user's locale. + + * Honour --enable-cache-owner in generated systemd tmpfiles snippet + rather than hardcoding "man". + + * If man adds prefixes to a page to handle such things as disabling + hyphenation, then take account of those when looking for a + preprocessor line at the start of the page. + + * Fix a segfault in 'man -D --help'. + + Improvements: + ------------- + + * Treat "\(en" as another synonym for "\-" in NAME sections. + + * Confine most subprocesses that handle untrusted data using + seccomp. This mainly deals with subprocesses that perform + encoding conversions, (de)compressors, groff programs, and a few + other odds and ends. groff programs use a slightly more + permissive filter since they need to create temporary files, so + additional path-based confinement (e.g. using AppArmor) is still + useful. + + If this goes wrong, then MAN_DISABLE_SECCOMP=1 can be set in the + environment to disable it, but please report any such problem as a + bug. + + * man now falls back to cat if the compile-time default pager is not + executable. + +man-db 2.7.6.1 (12 December 2016) +================================= + +Major changes since man-db 2.7.6: + + Fixes: + ------ + + * Don't chmod CACHEDIR.TAG if it doesn't exist. + + * Correct installation of Swedish manual pages. + +man-db 2.7.6 (11 December 2016) +=============================== + +Major changes since man-db 2.7.5: + + Fixes: + ------ + + * Fix build warnings with Perl 5.22. + + * Document that 'man -K' searches page source, not rendered text. + + * Fix a long-standing bug in man-db's internal cleanup stack + mechanism: if a cleanup function was pushed unexpectedly between a + push/pop pair, then popping the stack would remove the wrong + cleanup function and chaos could ensue. Avoid this by being more + precise about which cleanup function should be popped. + + * SECURITY: Eliminate dangerous setgid-root directories. In the + default configuration, cache files and directories are now owned + by man:man rather than man:root; man and mandb are now 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 that + caused my predecessor to make directories setgid root, 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. + + Maintainers of distribution packagers should take care to review + their installation rules in light of this change. + + As far as I know this has no CVE ID, but it is described here: + + https://www.halfdog.net/Security/2015/SetgidDirectoryPrivilegeEscalation/ + + * Fix manual page translation infrastructure to render tables + correctly with po4a 0.47. + + Improvements: + ------------- + + * man now understands the .

(As a result of this fix, man-db now requires + libpipeline >= 1.4.0.) + + * 'man -a' sends its prompts to /dev/tty rather than to stderr, and + likewise reads replies from /dev/tty rather than from stdin. + +man-db 2.7.0.2 (28 September 2014) +================================== + +Major changes since man-db 2.7.0.1: + + Fixes: + ------ + + * Be more careful to avoid using or double-closing closed database + handles.

This was broken by the LANGUAGE-handling fixes in + 2.5.4. + + Improvements: + ------------- + + * Ship a systemd tmpfiles snippet to clean up old cat files after a + week. + + * The modification time of manual databases is now simply stored in + the mtime of the database files themselves, rather than using a + special row. This makes databases reproducible between + otherwise-identical installations, as long as the underlying + database has predictable behaviour. As a bonus, man-db now uses + high-precision timestamps to determine whether it needs to update + databases. + + * Timestamps of manual pages are also now stored in the database + with high precision and compared accordingly. + + * Files are now ordered by first physical extent before reading + them, for substantial performance improvements in operations such + as mandb and 'man -K'. + + * 'man -H' shows a better error message if no browser is configured. + + * zsoelim is now installed in $pkglibexecdir, to avoid clashes with + other packages. + +man-db 2.6.7.1 (10 April 2014) +============================== + +Major changes since man-db 2.6.7: + + Fixes: + ------ + + * Remove test suite dependency on realpath(1). + +man-db 2.6.7 (10 April 2014) +============================ + +Major changes since man-db 2.6.6: + + Fixes: + ------ + + * Fix a test failure when configured with --enable-undoc. + + * Run the pager in man's original working directory rather than in + the manual hierarchy. (As a result of this fix, man-db now + requires libpipeline >= 1.3.0.) + + * mandb only creates a cache directory tag if the catpath is + different from the manpath, since it should only be created in + directories that consist entirely of cached information. + +man-db 2.6.6 (23 January 2014) +============================== + +Major changes since man-db 2.6.5: + + man-db is now revision-controlled using git (https://git-scm.com/). + See docs/HACKING for the location of the repository. + + Fixes: + ------ + + * apropos's --and option now works again; it was broken by the + optimisations in 2.6.2. + + * Restore compatibility with Automake 1.10. + + * Improve support for translation of common elements of help + messages. + + * Don't issue error messages when the database refers to a page that + no longer exists. + + * Pass macro and hyphenation language tags to groff again (broken in + 2.6.5). + + Improvements: + ------------- + + * ./configure --with-override-dir=OVERRIDE arranges to look for + manual pages in DIR/OVERRIDE before each path element DIR. + +man-db 2.6.5 (27 June 2013) +=========================== + +Major changes since man-db 2.6.4: + + Fixes: + ------ + + * man's --warnings option works again on systems with versions of + groff that support it (broken in 2.6.4). + + * man automatically falls back to C.UTF-8 and then en_US.UTF-8 if + trying to find a UTF-8 locale on a system without + /usr/share/i18n/SUPPORTED. + +man-db 2.6.4 (23 June 2013) +=========================== + +Major changes since man-db 2.6.3: + + Fixes: + ------ + + * man(1) and catman(8) now document the default section list set at + configure time. + + * Build fixes for Automake 1.13. + + * man-db 2.6.0 arranged to search the full manpath when expanding + .so directives in manual pages (so that ".so name.1" works as well + as ".so man1/name.1"), but this incorrectly did not take effect + for manual pages that consist only of a .so directive. This is + now fixed. + + Improvements: + ------------- + + * The MANLESS environment variable is now treated as if it were a + default value for the -r option to man: occurrences of the text + "$MAN_PN" are expanded, and explicitly using the -r option + overrides the default. + + * The (unfortunately still hardcoded) maximum length for paths to + manual page hierarchies in the configuration file is now 511 + characters rather than 49. + + * MANPATH entries now undergo glob(7)-style wildcard expansion, + allowing entries such as "/opt/*/man". + +man-db 2.6.3 (17 September 2012) +================================ + +Major changes since man-db 2.6.2: + + Fixes: + ------ + + * Build fixes for glibc 2.16 and Automake 1.12. + +man-db 2.6.2 (18 June 2012) +=========================== + +Major changes since man-db 2.6.1: + + Fixes: + ------ + + * apropos prints an error message and returns non-zero when it finds + no matches.

You must build and install + that library separately. + + * Search the full manpath when expanding .so directives in manual + pages. As part of this, '.so name.1' should now work as well as + '.so man1/name.1'. + + * lexgrog handles roff named glyphs and perldoc strings in NAME + sections. + + * man no longer starts a pager if standard output is not a tty. + + * The -s option to whatis and apropos now takes a colon- or + comma-separated list of sections, similar to 'man -S'. + + * mandb error output is neater when stderr is not a terminal. + + * Add basic support for the implementation of nroff/troff in the + Heirloom Documentation Tools. Title lengths are not properly set + as yet, and many features are untested. + + * mandb removes cat* and NLS subdirectories of cat directories whose + corresponding man directories no longer exist. + + * mandb forces SIGPIPE back to its default disposition on startup, + to avoid noisy output in case it was started in a context where + SIGPIPE was ignored. + + * SECTION entries in a user configuration file now override those in + the system configuration file, rather than appending to them. + + * The default less prompt now includes "(press h for help or q to + quit)" to help novices find their way around. + + * man-db may now be built to use Berkeley DB version 5 + (--with-db=db5). + +man-db 2.5.9 (17 November 2010) +=============================== + +Major changes since man-db 2.5.8: + + Fixes: + ------ + + * Fix test failures on some systems. A change made in 2.5.8 was + overly sensitive to directory ordering. + + * Configuring with --disable-nls works again. + +man-db 2.5.8 (15 November 2010) +=============================== + +Major changes since man-db 2.5.7: + + Fixes: + ------ + + * Fix assertion failure on 'man -l' with an uncompressed page and + any of --no-hyphenation, --no-justification, or a non-English + page. + + * 2.5.7 introduced a regression when running catman in some locales, + most notably in the C locale: while converting the output to + UTF-8, iconv was run after the compressor rather than before it. + This release fixes that. + + Improvements: + ------------- + + * Add support for XZ-compressed manual pages, thanks to Darren Salt. + + * Try underscore-separated subpages as well as hyphen-separated + ones, thanks to Tanguy Ortolo. + + * Build libman and libmandb as shared libraries, reducing installed + footprint by about 200K (at least on GNU/Linux). + + * libintl is no longer shipped with man-db. If your system does not + already have GNU libintl installed and you want man-db's messages + to be translated, then please install GNU libintl separately + (https://www.gnu.org/software/gettext/). + + * Warnings about unrecognised locales are now suppressed if the + DPKG_RUNNING_VERSION environment variable is set (i.e. man-db is + running within a Debian package's maintainer script), since the + system locales are often out of sync with the C library in that + context. Thanks to the Debian Perl maintainers for the idea. + + * Allow building with an external libpipeline + (https://nongnu.org/libpipeline/), which has been split out from + man-db. This is a transitional measure: a future version of + man-db will stop shipping its own copy of libpipeline. + + * mandb should no longer repeatedly rescan manual page hierarchies + when a whatis entry turns into a broken link. + +man-db 2.5.7 (16 February 2010) +=============================== + +Major changes since man-db 2.5.6: + + Fixes: + ------ + + * If a subprocess exits before man manages to read all the output + from it, it now drains the output file descriptor rather than + immediately discarding it. + + * If /usr/share/i18n/SUPPORTED is available, man attempts to use it + to ensure that LC_CTYPE is set to an appropriate locale for the + selected character set when invoking col. This fixes 'LANG=C man + -E UTF-8', as used by lintian. + + * Don't run tests if cross-compiling. + + * Fix possible mandb crash when MAN_MUST_CREATE is unset. + + Improvements: + ------------- + + * man can now tell nroff to disable justification if the + --no-justification option is used. + + * If the full path to an executable is given as an argument, man + will try looking up the corresponding manual page in the + appropriate part of the manpath, rather than just trying to format + the text of the executable as a manual page. + + * In the GNU manual hierarchy layout, search man + directories as well as just man (e.g. /usr/share/man/man3p as + well as /usr/share/man/man3). + + * By request, man now prefers getting a page from the best manual + section over getting a page in the correct language. + + * All programs now support a MAN_DEBUG environment variable which + can be used in place of the -d/--debug option. This is useful in + some situations where a program is being called deep in a process + tree. + + * man-db now builds with heirloom-doctools, thanks to Diego Pettenò + of Gentoo. + + * Add support for emulating pipe() with socketpair(), which is + faster on some systems; thanks to Werner Fink of SUSE. + + * Cat pages are now always saved in UTF-8, and converted to the + proper encoding at display time, which means that cat pages can + now be saved regardless of locale. Note that a consequence of this + is that cat pages now include formatting information (e.g. + overstriking) and need to be run through col(1) before display. + +man-db 2.5.6 (26 August 2009) +============================= + +Major changes since man-db 2.5.5: + + Fixes: + ------ + + * Exact-section database lookups were incorrectly returning all + database entries whose section names were prefixes of the + requested section name. In some cases this could confuse mandb + into never believing that the database was up to date. + + * Fix handling of pages with comma-separated names ("foo, bar, + baz") in their NAME sections, broken by a change in 2.5.0 (!) + to ignore manual page names containing spaces. + + * Fixed a buffer overflow in the pipeline library's line-reading + functions. I don't believe this to be exploitable: at worst we + might believe that there's some garbage at the end of manual pages + (whose contents are untrusted anyway) and this bug typically + resulted in a failed assertion the next time anything tried to + read a line. + + * Plugged two substantial memory leaks in the pipeline library. + + * whatis and apropos only display any given manual page, or pointers + to it, once. + + * man now sets less(1)'s environment up correctly for manual pages + encoded in CP1251. + + * manconv no longer confuses situations such as "this UTF-8 + character is not representable in the target encoding" with "this + text is not in UTF-8". + + Improvements: + ------------- + + * The default configuration file now includes section 0, used on + some systems to document C library header files. + + * 'make check' now passes in the presence of a UTF-8-aware col, such + as that in util-linux-ng. + + * The 'man -K' option is now supported to search the full text of + all manual pages. This was inspired by a similar option in the + other man package (currently at version 1.6f) currently maintained + by Federico Lucifredi and formerly by Andries Brouwer, but I took + advantage of man-db's pipeline library to implement it entirely + in-process, without having to start a separate grep process for + every manual page. In my tests with fairly typical searches across + variously all manual pages or just one section, man-db's + implementation ran between 3 and 10 times faster. + + * Database directories are now only created when there are + corresponding manual page directories, not just because they're + mentioned in the configuration file. + + * By default, man will now try to interpret pairs of manual page + names given on the command line as equivalent to a single manual + page name containing a hyphen (e.g. 'man foo bar' => foo-bar(1)). + This supports the common pattern of programs that implement a + number of subcommands, allowing them to provide manual pages for + each that can be accessed using similar syntax as would be used to + invoke the subcommands themselves. Suggested by H. Peter Anvin, + Federico Lucifredi, and others on the git mailing list. + + * The build process is now quieter by default. Use './configure + --disable-silent-rules' or 'make V=0' if you don't like this or + your make(1) doesn't support the non-standard extension required. + + * 'make install' now installs the manual. + + * manconv understands a wider range of Emacs-style coding tags. + + * Recommendations to change MAN_DB_CREATES, MAN_DB_UPDATES, and + MAN_CATS #define options in manconfig.h have been replaced by new + configure options --enable-automatic-create, + --disable-automatic-update, and --disable-cats respectively. Note + that automatic user database creation is now off by default, as it + is often too slow for the usefulness it adds; use + --enable-automatic-create to enable it. + +man-db 2.5.5 (14 March 2009) +============================ + +Major changes since man-db 2.5.4: + + Fixes: + ------ + + * Pages that declare a non-default encoding in their preprocessor + lines are now handled correctly. + + * Fix an uninitialised variable when sorting manual page candidates + that could lead to excessive memory allocation and possible + crashes. + + Improvements: + ------------- + + * man-db's 'make check' now tests that all its own manual pages + format without errors or warnings from groff, to ensure a + better-quality release. + +man-db 2.5.4 (24 February 2009) +=============================== + +Major changes since man-db 2.5.3: + + Fixes: + ------ + + * Build fixes for systems without GNU Make, and for systems without + gettext; this successfully covers at least FreeBSD. + + * The distclean target now works if po4a isn't installed. + + * Exit as soon as possible if database writes return ENOSPC. + + * lexgrog now stops on any unrecognised roff request, rather than + continuing and often littering the database with garbage. + + * man no longer requires both standard input and standard output to + be terminals in order to use the terminal line length. The line + length from standard output is preferred if available. + + * The manpath was built completely wrongly when multiple entries + were present in LANGUAGE: duplicates were handled strangely, and + languages were effectively iterated in reverse order. It should be + rather more sensible now. + + Improvements: + ------------- + + * The MAN_KEEP_STDERR environment variable can now be used to + override man's default of discarding stderr when stdout is a + terminal. + + * Handling of terminal widths for cat pages is now configurable, + using the MINCATWIDTH, MAXCATWIDTH, and CATWIDTH configuration + file directives. + + * 'man -a' now detects duplicate manual page candidates more + reliably, and sorts them better. + + * Belarusian, Estonian, Greek, Latvian, Lithuanian, Macedonian, + Romanian, Slovenian, and Ukrainian pages are now supported. + + * man can now search for pages using regular expressions (with + --regex) or shell wildcards (with --wildcard). By default this + searches both page names and descriptions, like apropos, but if + the --names-only option is used then it searches page names only, + like whatis. + + * man can now tell nroff to disable hyphenation if the + --no-hyphenation option is used. + + * man-db already searched for manual pages in ../man and man + directories relative to each $PATH component; it now searches in + ../share/man and share/man directories too. + + * Groff 1.20 was recently released, including the 'preconv' + preprocessor. Although man-db has supported preconv to some extent + since 2.4.4, man-db's configure now detects its presence and + infers that groff supports Unicode input using it; man also now + takes slightly better advantage of preconv than before. + + * Per-locale groff macros are now loaded if possible, allowing us to + take advantage of such things as localised versions of predefined + strings and language-aware hyphenation. This only works with Groff + 1.20.2 or better (not yet released), since earlier versions did + not allow us to suppress warnings in the event that the + appropriate macro file is not available. + +man-db 2.5.3 (17 November 2008) +=============================== + +Major changes since man-db 2.5.2: + + Fixes: + ------ + + * Cleaned up a number of possible crashes, memory leaks, and missing + error checks found by the Coverity Scan project. + + * Fix build if MAN_CATS is undefined. + + * If the LINGUAS environment variable is set while running + configure, it now controls building and installation of localised + manual pages as well as program translations. + + * The LANGUAGE environment variable is now tokenised properly, + rather than only taking the first two characters of each element. + + * Fix build if --disable-nls is used or iconv is not available. + + * man now correctly propagates the exit code of whatis or apropos + when called with the -f or -k option respectively. + + Improvements: + ------------- + + * A number of inconsistencies and readability problems with man-db's + own manual pages have been cleaned up, thanks mainly to Yuri + Kozlov. + + * Reduce the number of warnings emitted when using an unrecognised + locale. + + * manconv and zsoelim are now called internally rather than by + executing external programs, to improve performance. + + * man-db now uses GDBM (--with-db=gdbm) in preference to Berkeley DB + (--with-db=db or --with-db=dbN where N is 1, 2, 3, or 4) by + default, since hardware improvements have rendered Berkeley DB's + speed advantages negligible for our purposes and the relatively + frequent SONAME and on-disk format changes are not worth the + hassle. Distributors should note that if they follow this change + then they will need to arrange for databases to be rebuilt on + upgrade to this version. + + * Manual pages may now be compressed with LZMA (although this is + probably only worth it for very large pages). + + * Duplicate manual page hierarchies due to symlinks (e.g. /usr/man + -> /usr/share/man) are detected and removed from the search order. + + * A locale modifier (e.g. @latin) in a directory name must now match + the locale if the former is set, in addition to the language and + territory. + + * Bare .so includes (e.g. ".so foo.1" rather than ".so man1/foo.1") + now work, although only within the same manual page hierarchy for + now. + +man-db 2.5.2 (5 May 2008) +========================= + +Major changes since man-db 2.5.1: + + Fixes: + ------ + + * 'man -H' (without a browser argument) was completely broken in + 2.5.1 and is now fixed. + + * man no longer breaks in Japanese locales when using less as a + pager. + + Improvements: + ------------- + + * The --encoding option to man can now take a true character + encoding rather than a *roff device; the latter was an unreliable, + inflexible, and awkward way to select an output encoding. The old + semantics are still supported for backward compatibility. + + * Whatis parsing stops at .ie or .if conditionals. + + * CJK locale specifications where the codeset component is + equivalent to but not stringwise-identical to UTF-8 (e.g. + zh_CN.utf8) are handled better. + + * man(1)'s OPTIONS section is ordered more comprehensibly. + + * apropos, lexgrog, man, mandb, and whatis ignore encoding + conversion errors for the last possible encoding of the source + page. This helps, for example, with pages including misencoded + non-ASCII names of authors; it usually seems better to allow these + pages to pass with small errors than to break them entirely. + +man-db 2.5.1 (28 January 2008) +============================== + +Major changes since man-db 2.5.0: + + Fixes: + ------ + + * The manual is now built automatically, avoiding some ordering + problems on 'make distclean'. + + * Manual pages are converted to the proper input encoding for troff + output as well as nroff output. + + * The -t, -T, -X, and -Z options to man work again; in 2.5.0, they + read input from stdin rather than from the manual page. + + * apropos and whatis no longer segfault when given an explicit + locale using -L. + + * man now understands that groff's ascii device takes ASCII input, + not ISO-8859-1. + + * man no longer discards stderr when writing to a file or a pipe; + this was broken by an overenthusiastic change in 2.5.0. + + * manconv now falls back to the next encoding in its list if any + characters in an entire 64KB block fail to decode using the + current encoding, as was originally intended. + + * manconv is more careful about extracting coding: directives from + manual pages. + + * Ctrl-C and Ctrl-\ now work again at the prompt issued by 'man -a'. + + Improvements: + ------------- + + * There is a new --with-sections configure option to change the + default value of SECTION in the configuration file. + + * Automake is now used to generate Makefiles. Among other things, + this fixes VPATH builds and some bugs in dependency generation, + and should allow building with non-GNU versions of make. + + * man-db now uses the Gnulib portability library, allowing the + removal of earlier haphazard portability code. While this results + in a somewhat larger source distribution, it makes man-db easier + to maintain and should make it easier to build on systems to which + the maintainer does not have access. + + * In the process of switching to Gnulib, the last vestiges of + pre-C89 support have been removed; they were documented to be + broken anyway. + + * If the MANROFFOPT environment variable is set, man now appends its + value to the *roff command line. + + * man now accepts a --recode option to output a source manual page + converted to a specified encoding. + + * For compatibility with System V, man accepts -s as an alias for + -S, and permits sections to be comma-separated as well as + colon-separated. + + * All programs, except the obsolete 'wrapper', now accept a --debug + option. (accessdb, lexgrog, and zsoelim were lacking it.) + + * man now accepts a --warnings option to enable groff warnings. + +man-db 2.5.0 (7 October 2007) +============================= + +Major changes since man-db 2.4.4: + + Fixes: + ------ + + * mandb --quiet now suppresses several more warnings. + + * The output of apropos no longer includes duplicates when multiple + search terms are used. + + Improvements: + ------------- + + * Databases are now created for non-English manual hierarchies. All + database entries should be encoded in UTF-8; man-db converts from + the character set of the manual hierarchy and to the character set + specified in the user's locale as necessary. + + * Per-locale directory handling has been improved. Directories such + as "fr.UTF-8" may be used for occasions when it is appropriate to + specify the character set but not the country, and so a full + locale name is inconvenient. + + * There is a new "manconv" program which can try multiple possible + encodings for a file, thus allowing UTF-8 manual pages to be + installed in any directory even without an explicit encoding + declaration. + + * A decompression library is now in place. This allows man-db to use + zlib to decompress gzipped files, and allows most of its uses of + temporary files to be removed. The only remaining exceptions are + cat file creation (which uses a temporary file in the cat tree + rather than in /tmp) and viewing HTML manual pages (which uses a + temporary directory). Otherwise, man-db should now work fine even + with a read-only /tmp during system recovery. + + * Cat pages are now saved in the background while the pager is + active, so man will only need to block afterwards if the pager is + exited very quickly. + + * --with-* options are now available at configure time for most of + the auxiliary program locations that you might want to override. + + * man now supports the MANPAGER environment variable, overriding + PAGER. + + * apropos/whatis output is now truncated to the terminal width by + default. As with man, this may be overridden using the MANWIDTH + environment variable. + + * lexgrog now ignores alleged manual page names containing spaces, + as these usually indicate parsing errors or ill-formed NAME + sections and they clutter up apropos output badly. I'm only aware + of one legitimate counterexample, the Intercal compiler "oo, ick", + which no longer appears to be known by that name anyway; let me + know if there are any others. + + * man now discards stderr from formatting subprocesses when + outputting to a pager, to avoid visual corruption from any error + messages. + + * If the MAN_KEEP_FORMATTING environment variable is set to any + non-empty value, then man will preserve formatting characters in + its output even when standard output is not a terminal. This may + be useful for programs such as pinfo that call man and can + interpret its formatted output. + + * Setting NOCACHE in the configuration file now prevents man from + ever creating cat pages automatically. + + * apropos now accepts the --and option to display only items that + match all the supplied keywords. + +man-db 2.4.4 (12 February 2007) +=============================== + +Major changes since man-db 2.4.3: + + man-db is now revision-controlled using bzr + (https://bazaar.canonical.com/). See docs/HACKING for the location + of the archive (including all CVS history, imported by Canonical). + + Fixes: + ------ + + * SECURITY: Fix a buffer overrun if using -H and the designated web + browser (argument to -H or $BROWSER) contains multiple %s + expansions. This is CVE-2006-4250. + + * Ignore SIGINT and SIGQUIT while running subprocesses, so that + typing Ctrl-C doesn't kill less (broken in 2.4.3). + + * Similarly, ignore SIGPIPE in subprocesses. + + * Various fixes to SIGCHLD handling in pipeline library, preventing + "waitpid failed: No child processes" errors. + + * Skip "exec" in configuration file commands (perhaps left over from + old installations), which the pipeline execution library cannot + handle directly. + + Improvements: + ------------- + + * Add support for Chinese in the --enable-mb-groff case. + + * lexgrog now handles pages with multiple descriptions more + usefully, by displaying one description per output line. + +man-db 2.4.3 (3 July 2005) +========================== + +Major changes since man-db 2.4.2: + + Fixes: + ------ + + * Avoid problems creating databases on systems with badly broken + clocks set before the Unix epoch. + + * Fix detection of decompression programs, so that man doesn't + attempt to execute man pages when it doesn't have a corresponding + decompression program. + + Improvements: + ------------- + + * apropos and whatis now accept a --section option to restrict their + search to a particular manual section. + + * The pipeline execution library is now used for most calls to + external programs, avoiding use of the shell. + + * When stdout is not a terminal, man pages will be formatted in + plain text without the use of backspace or ANSI formatting + characters. + + * When invoking apropos (man -k) or whatis (man -f) as external + programs, man now only passes through command-line options + understood by the respective programs. + + * Improve handling of locales with versions and/or modifiers. + + * Add support for Croatian, Galician, Indonesian, Slovak, and + Turkish pages. + + * man-db may now be built to use Berkeley DB version 4 + (--with-db=db4). + + Compatibility notes: + -------------------- + + * Setting the line length of manual pages now requires groff 1.18 or + later. + +man-db 2.4.2 (20 September 2003) +================================ + +Major changes since man-db 2.4.1: + + Fixes: + ------ + + * SECURITY: Fix a number of buffer overruns in configuration file + handling, ultimate source location, and MANPATH processing. This + is CVE CAN-2003-0620. + + * SECURITY: Restrict the use of the DEFINE directive in ~/.manpath + to code running with dropped privilege. Previously, the + 'compressor' variable could be used to run arbitrary code with + raised privilege. This is CVE CAN-2003-0645. + + * Make sure to initialize mandata structures to zero. The uses of + uninitialized memory resulting from this had been leading to + random segfaults. + + * Drop privileges in order to be able to read pages in + non-world-readable user manpaths while setuid. + + * man can be built with --disable-setuid again. + + * man's locale support has been revamped. The encoding of source + manual pages is no longer related to the encoding of the input + passed to *roff or to *roff's terminal output device. These + frequently differ, especially in UTF-8 locales but in other + circumstances as well, and a "just send 8-bit data" approach is no + longer adequate. If you are using a version of groff with the + Debian multibyte patch applied, pass the --enable-mb-groff option + to configure. + + * When using GDBM, accessdb and apropos did not return database + entries in sorted order, since GDBM's key traversal interface is + not lexicographically ordered. The database layer has been + corrected to cope with this. + + * Directories found in strange places in manual hierarchies don't + crash mandb. + + Improvements: + ------------- + + * man now calls mandb to update databases rather than doing it + itself. This leaves cat pages as the sole remaining reason for man + to be setuid. + + * The "undocumented" message is only displayed if a corresponding + executable is found on the $PATH. + + * All programs that read ~/.manpath now take a -C option to cause + them to read a different user configuration file instead. + + * The --enable-debug option to configure has been removed. man-db's + Makefiles now always calculate full dependencies for C files. + + * mandb caches the contents of directories, significantly speeding + up the purging of obsolete entries. + + * mandb now knows how to purge database entries corresponding to + removed stray cat pages. + + In addition, a pipeline execution library has been written, which + will make it possible to eliminate all or almost all use of the + shell in a future release. Unfortunately, time pressures due to the + security issues above meant that the pipeline library was not well + enough tested for use in this release, so it is present but unused. + That will be the first item for 2.4.3. + +man-db 2.4.1 (22 December 2002) +=============================== + +Major changes since man-db 2.4.0: + + The man-db CVS repository has moved from sourceforge.net to + savannah.nongnu.org. + + Fixes: + ------ + + * Don't enter an infinite loop when the SYSTEM environment variable + is set. + + * man doesn't segfault when trying to follow a broken symlink. + + * mandb no longer corrupts databases when deleting entries that are + part of multi keys. + + * Prevent a possible buffer overflow when encountering large multi + keys. + + * Man page names are escaped when globbing, so [(1) can now be found + even if the database is not up to date. + + * Correct an access() check that led to 'man -X -l -' producing no + output. + + * lexgrog can now cope with man pages containing only a .so link. + + * Manual hierarchies with a specific encoding are put into the + search path in the correct order. A bug in $LANGUAGE handling had + formerly meant that 'de' would take precedence over 'de_DE.UTF-8'. + + Improvements: + ------------- + + * man's behaviour when searching for page names that begin with a + digit has been made more intuitive, as has its treatment of + section names that are extensions of ones mentioned in the + configuration file but are not themselves explicitly named as + sections. + + * The default line length for pages formatted for terminal output + has been increased (reducing margin size) to match the default in + groff 1.18. + + * Proofread the manual. + + * The -w flag to man has been changed to display the name of only + the source nroff file. A -W flag has been introduced which + displays the name of the cat file as well. If both flags are given + to man, it will behave as before. + + * If bzip2 is installed, pages compressed with bzip2 can now be + displayed. + + * Add support for displaying an additional message when no man page + is found, which can be used to direct users to a generic + "undocumented" page. + + * The manual hierarchy layout will now be guessed where possible if + an explicit --enable-mandirs argument is not passed to configure. + +man-db 2.4.0 (26 June 2002) +=========================== + +Major changes since man_db-2.3.20: + + I have changed the package name to man-db, as the underscore was + awkward. + + Upgrading from version 2.3.x: + ----------------------------- + + The database format has changed slightly, so you will need to run + 'mandb --create' after installing the new version to rebuild your + databases from scratch. (Distribution packages should do this + automatically for system databases.) + + Fixes: + ------ + + * The GNU nroff test in configure now works when /bin/sh is ash. + + * When scanning pages for NAME sections, lexgrog and mandb no longer + accidentally eat the line after each occurrence of the no-op + request '.'. + + * 'man --local' drops privileges throughout to avoid problems with + non-world-readable home directories. + + * Newly created cat directories are chowned to the man user when + running as root. + + * 'man --html' no longer creates its temporary file with raised + privileges, so that it now works with a setuid man. + + * man detects preprocessors correctly when setuid. + + * Various segfault fixes: explicitly null-terminate data returned by + the Berkeley DB library to avoid some rare crashes; don't reuse a + freed pointer in some cases of pages with multiple names; handle + MANPATHs containing '::' more safely. + + * Correctly parse manual pages using DOS line-ending conventions. + + * Work around a misfeature in Berkeley DB: it pauses for several + seconds if asked to read a zero-length database, on the assumption + that somebody is still writing the metadata page. man is generally + better off just ignoring the database in this case. + + * Work around corrupted databases in the case where the nextkey + pointer chain contains a loop. + + Improvements: + ------------- + + * man looks in the filesystem followed by the database, rather than + the other way round. Unix filesystems are quite good databases for + this purpose, and the man database is only superior when looking + up names that don't have associated links in the filesystem. + + * 'apropos --wildcard --exact' makes sure wildcards match an entire + description or page name, unlike 'apropos --wildcard' which may + match on word boundaries too. + + * man's page-searching code has been substantially rearranged, and + now only starts displaying pages when it has finished searching + for candidates. This allows pages to be sorted more sensibly. + + * Manual pages are formatted in UTF-8 if that is the current + locale's character set. The -E option is now available to force a + particular encoding. Note that some versions of (e.g.) less have + problems displaying UTF-8 in conjunction with backspace + characters; groff 1.18 should alleviate this by using ANSI colour + escapes instead. + + * The less prompt string sets -PM as well as -Pm. + + * Invoking man from within less now sets the correct page title in + the inner less. + + * Unless the --match-case option is used, man will search for pages + case-insensitively. + + * Update the mechanism for setting the line length so that it also + works with groff 1.18. + + * The -R switch is added to the less prompt string, which is needed + to display the ANSI colour escapes generated by groff 1.18 + correctly. + + * The $MANLESS environment variable may be used to override the + normal creation of the less prompt string. + + * Translation updates for French, German, and Spanish, and a new + Catalan translation. See man/THANKS. + +man_db-2.3.20 (7 September 2001) +================================ + +Major changes since man_db-2.3.19: + + Fixes: + ------ + + * A typo in 2.3.19 caused character sets for many languages to be + detected incorrectly. This especially affected multibyte + languages. + + * Long options in the environment variable LESS are handled + correctly. + + * When checking if cat pages need to be updated, check for different + timestamps rather than whether the cat page is newer, as otherwise + we were confused by tools like tar that preserve timestamps in + their archives. Each cat page is now set to have the same mtime as + its corresponding man page. + + * Look up the correct character set each time a page is displayed + rather than just the first time, in case pages in several + different character sets are viewed in a single session. + + * groff requests are no longer assumed to be case-insensitive when + scanning for preprocessors, so for example mdoc's .Eq request + isn't mistaken for the .EQ which introduces eqn commands. + + * Escape arguments passed to the shell that might contain dangerous + characters. + + * Avoid an infinite loop if the LANGUAGE environment variable is set + but empty. + + * The --create option to mandb now implies --no-purge. + + * Temporary files are handled with more secure permissions. + + Improvements: + ------------- + + * Use a variant of mkstemp() rather than tempnam(), to avoid classic + race conditions. (I don't believe the races were usefully + exploitable.) + + * Tolerate whatis entries in a database that point to themselves. + + * Detect more translations of the NAME section. + + * Add examples of man pages written in POD and SGML. + + * lexgrog is now installed in /usr/bin by default, with proper + argument parsing, an improved output format, and a man page. It is + expected to be used by programs that need to validate man pages. + + * The -H (--html) option to man is now compiled in by default, and + supports the BROWSER specification (as documented at + http://www.tuxedo.org/~esr/BROWSER/ and amended at + https://www.dwheeler.com/browse/secure_browser.html). + +man_db-2.3.19 (5 July 2001) +=========================== + +Major changes since man_db-2.3.18: + + Fixes: + ------ + + * The user configuration file ~/.manpath is no longer trusted when + deciding whether to drop privileges. In the process, user cat + directory handling has been improved. + + * Commands of the form 'man -S "" foo' formerly emptied the list of + acceptable sections and then searched the database anyway, and + commands of the form 'man -S ::: foo' segfaulted. Both now use the + standard list of sections. + + * The HUP and TERM signals are now handled better. + + * straycats processing invokes 'col -bx' rather than 'col-bx'. + + * The root user is now correctly allowed to update databases in + system manpaths. + + * apropos and whatis no longer enter infinite recursion if a + database contains an entry pointing to itself. + + Improvements: + ------------- + + * When compiled with --enable-setuid, man and mandb can be installed + non-setuid. In this mode, they will be unable to write cat pages + in system directories or to modify system databases, but will + otherwise operate correctly. This allows a single binary package + to support setuid and non-setuid modes of operation. + + * The ordering of manual sections is read from SECTION directives in + the configuration file rather than being hard-coded. + + * The MANDB_MAP configuration file directive is documented more + clearly. + + * Multiple whatis entries separated by commas, break requests, + and/or paragraph requests are handled more intelligently. + + * Fill control requests (.nf and .fi) cause lexgrog to assume a + break at each newline. + + * Duplicate manpath entries (often generated in the course of + national language support) are removed, so that 'man -a' works + better. + + * man_db's binaries are installed unstripped by default. + + * Since supporting certain layouts of manual page hierarchies causes + problems for others, the layout is now selectable via configure. + The default is to try all layouts. + + * man only does an on-the-fly update of the database caches when the + --update option is given. + + * Manual pages are displayed with a line length appropriate to the + current terminal. If a non-standard line length is used (i.e. the + terminal is not between 66 and 80 characters wide) then cat pages + will not be saved. + + * mandb tries to purge obsolete entries from its databases. Using + the --create flag should now usually only be necessary in cases of + database corruption. + +man_db-2.3.18 (14 May 2001) +=========================== + +Major changes since man_db-2.3.11: + + man_db-2.3.18 is an interim release under new maintenance by Colin + Watson, merging much of the work done by former maintainers (Graeme + Wilford and Fabrizio Polacco). It incorporates several years of + changes made in the Debian GNU/Linux distribution's package of + man_db. + + Here are a few highlights, with the names of the maintainers + responsible for them. As I am documenting after the fact of other + people's changes of a few years ago, I have undoubtedly missed a + number of fixes and improvements; I promise to keep track of these + as I go along in future. + + Fixes: + ------ + + * Multiple security fixes, including better handling of temporary + files, a format string vulnerability fix, and more careful + dropping of privileges when running setuid. [Fabrizio, Colin] + + * Databases no longer disappear temporarily while they are being + regenerated. [Fabrizio] + + * Corrected handling of locale environment variables. Setting + several colon-separated locales in $LANGUAGE also works now. + [Colin] + + * whatis and apropos are more careful about the possibility of a + corrupted database. [Fabrizio, Colin] + + Improvements: + ------------- + + * If root has private manual hierarchies, cat pages generated from + them are no longer chowned to a less-privileged user. [Wilf] + + * Rewrote configuration file handling, adding DEFINE directives to + set paths to external programs. The configuration file is now + called man_db.conf. [Wilf] + + * Support FHS paths (/usr/share/man and /var/cache/man) in + preference to FSSTND paths (/usr/man and /var/catman). [Fabrizio] + + * Converted from catgets to GNU gettext for national language + support. [Fabrizio, Colin] + + * Several new and improved localized message catalogues and + translated man pages. [Fabrizio, Colin, other contributors] + + * Added accessdb utility, which displays the contents of a manual + page database. [Fabrizio] + + * Added user configuration file ~/.manpath, with the same syntax as + the global configuration file. [Fabrizio] + + * Leading or trailing colons in the MANPATH environment variable + cause the manpath derived from configuration files to be prepended + or appended respectively. A double colon in the middle of the + environment variable causes the configuration file manpath to be + inserted between the colons. [Fabrizio] + + * Added experimental -H and -Thtml options to take advantage of + groff's new HTML driver. [Fabrizio] + + * lexgrog now scans manual pages to guess which preprocessors are + needed. [Fabrizio] + + * Create cat directories on the fly if necessary. [Fabrizio] + + * Supply a wrapper which explicitly drops privileges to uid man if + man or mandb is run as root. In the future, splitting out setuid + functions into a separate helper process may remove the need for + this paranoia. [Fabrizio] + + * Add --test option to mandb, which merely reports errors in manual + page hierarchies rather than actually creating or updating a + database. [Fabrizio, Colin] + + * Manual pages may now be symlinks outside the mantree. This should + pose no significant security concerns, and utilities such as GNU + stow create such symlinks. [Colin] + + * Deprecate whatis references for man, and display a warning if + displaying a page relies on going through a whatis reference. They + often lead to confusingly non-obviously-deterministic behaviour, + and guaranteeing that man will honour them even when the database + is out of date causes performance problems. [Colin] + +man_db-2.3.11 (21 September 1995) +================================= + +Major changes since man_db-2.3.10: + + * The man_db manual is bundled in source form. + + * Components of $PATH not in the config file were checked for + `man' subdirectories. Now they are also checked for `../man'. + + * Untarring a new manual page (with a timestamp older than the + relative cat file) over the original did *not* cause man/catman + to reformat the replacement. This is changed. As a side effect, + untarring an unchanged man file over the original will also cause + a reformat. + +man_db-2.3.10 (13 July 1995) +============================ + +Major changes since man_db-2.3.5: + + Fixes: + ------ + + * Global databases were not owned by setuid owner (if applicable). + As a consequence only mandb could update the databases unless + man was run by superuser. Stupid bug. + + * The keyword passed to apropos _never_ matched the first word + of any whatis line. + + * FAVOUR_STRAYCATS code (if enabled), did not work properly. + + * zsoelim did not work as advertised. + + Improvements: + ------------- + + * Man removes its temporary files upon abnormal termination. + + * apropos does proper word matching rather than the fuzzy + matching of 2.3.5. eg. supplying any of the keywords: + `ld.so', `a.out', `dynamic', `linker' or `loader' will match + the following entry: + + ld.so (8) - a.out dynamic linker/loader + + whereas `a.out' and `loader' used to fail. + + * man/whatis/apropos return with exit code 16 if manual + page/file or keyword is not matched. Previously exit code 0 + was used making it difficult for callers to know if the lookup + was successful. + + * addition of German message catalogue. + + * `apropos' and `man -k' do POSIX specified regex matching rather + than keyword searches if the environment variable POSIXLY_CORRECT + is defined. + + * added glob-only support of native system manual hierarchies + on HP-UX, OSF and Solaris operating systems. Improved the + whatis parsing code to cope with majority of HP-UX manual pages. + + * ported to NeXTstep. + +man_db-2.3.5 (21 April 1995) +============================ + +Major changes since man_db-2.2.1: + + Added support for... + -------------------- + + * Non-standard section names i.e. multi-character + + * Compressed manual pages. + A new utility `zsoelim' is included to correctly handle nroff + .so requests that point to a file which has been compressed. + + * Compressed stray cats. + By definition, stray cats are not re-creatable as they have no + relative source manual page. As they may have non-default + compression extensions and may reside on read-only media, + stray cats have the same compression support as manual pages. + + * FSSTND proposed `extension' support. + Specific package manual pages may be installed in the standard + sections but with a package-unique extension appended as in + exit(3tcl) - ../man/man3/exit.3tcl. Using the command + + `man -e tcl exit' + + would then display an exit manual page with a tcl extension, if + available. Of course, `man 3tcl exit' works as always. + + * FSSTND proposed NLS man subdirectories. + Of the form .../man//man/ + + * NLS message catalogue hooks. + Provision has been made for the programs to emit their messages in + a language dependent form. + + * `whatis' referred manual pages. + Some manual pages contain relevant information for commands or + programs that would not otherwise reference the page. + The `whatis' part of the manual page is used to create virtual + links to these pages by all of the names mentioned within it. + Examples include names such as `.' and `:' referencing the local + shell manual page. + + * Catman utility. + Used to pre-format the manual pages into cat pages. + + * Operating systems other than Linux. + man_db has been reported to compile on the following platforms: + + Linux, SunOS, Solaris, Ultrix, OSF, HP-UX, AIX, IRIX + + (although portability does not extend to support of native + manual tree structures on some of these systems, eg.

Unless you take special +pains to remove the GPL v3 portions, you must therefore follow the terms and +conditions of the GPL v3 or later when distributing man-db. + + +Notice regarding current state of FHS (Linux/?BSD) +================================================== + +As of May 13th, 2001, the last public release of the Filesystem Hierarchy +Standard proposed the root of the manual page hierarchy as `/usr/share' and +the root of the writable cat hierarchy as `/var/cache/man' for the purposes +of man->cat filename translation. As such, the following are defined in +./include/manconfig.h.in: + +#define FHS_CAT_ROOT "/var/cache/man" /* required by fsstnd() */ +#define FHS_MAN_ROOT "/usr/share" /* required by fsstnd() */ + +For compatibility with the old FSSTND, the following locations are also +defined: + +#define CAT_ROOT "/var/catman" /* required by fsstnd() */ +#define MAN_ROOT "/usr" /* required by fsstnd() */ + +Should these locations change, simply define the paths accordingly and +recompile. Other FHS changes relating to man/cat paths will not be +compatible with this version of man-db. + +Non-generic arguments to configure +================================== + +To allow the configuration program, configure, to be non-interactive, it can +be passed various options to alter the default settings. Generic configure +options are discussed in docs/INSTALL.autoconf. The following list of +options is extracted from the man-db manual. It is strongly recommended +that relevant sections of the manual are read if any of these options are +used. + +--enable-cache-owner[=ARG] + By default, system-wide cache files will be owned by user man. Use this + option with an argument to change the cache file owner. + +--disable-cache-owner + Use this option to leave the ownership of system-wide cache files + unconstrained. Users will be allowed to modify them. + +--disable-setuid + By default, man will be installed as a setuid program to the user that + owns the system-wide cache files. Use this option to install man as a + non-setuid program instead. + +--enable-mandirs=OS + By default, man-db supports manual page directories in any of several + layouts used by free and proprietary versions of UNIX. However, in + certain cases, this can cause man-db to find the wrong page by mistake, + especially when the names of some manual pages on the system contain + periods. Use this option with an argument of GNU, HPUX, IRIX, Solaris, + or BSD (or more than one of these, separated by commas) to support only + the layouts typically used on each of those systems. Note that man-db is + not currently capable of writing cat pages in the proper BSD layout. + +--with-device=DEVICE + Use this flag to alter the default output device used by NROFF. DEVICE is + passed to NROFF with the -T option. configure will test that NROFF will + run with the supplied device argument. + +--with-db=LIBRARY + configure will look for database interface libraries in the order gdbm, + Berkeley DB and finally ndbm and will #define appropriate variables + relative to the first one found. To override the built-in order on + platforms having a choice of interface library, use this option to + specify which library to use. + +--enable-automatic-create + If this flag is used, man will automatically create index databases for + users' private manual page hierarchies. + +--disable-automatic-update + Normally, man will update entries in index databases if it finds newly + installed manual pages (if the --update flag is used) or delete entries + if manual pages are removed. This flag suppresses this behaviour. + +--disable-cats + Normally, man will automatically try to create cat files corresponding to + manual files when a manual page is read. This flag suppresses this + behaviour. + +--disable-manual + Don't build or install the man-db manual. This may be useful when + cross-compiling, or to reduce the installation size. + + +INSTALL +======= + +Running configure. + + * READ `docs/INSTALL.autoconf' regarding ./configure options + + * RUN `./configure --help' to see what --enable and --with + options may be useful. + + * RUN `./configure' with the appropriate options and environment + variable settings + +BROWSE or EDIT the following files that were created by the configuration +process. + + * `include/manconfig.h' regarding paths to support programs, + the default section list and other specific definitions. + + * `include/comp_src.h' if the default compressor support is + inadequate for your requirements. (usually .Z [compress], + .z, .gz [gzip]) + +configure will determine your system's ability to use native language +support (NLS) message catalogues. You may set the environment variable +LINGUAS to limit the set of translations installed. LINGUAS should contain +a space-separated list of two-letter language identifiers. To compile +man-db with no support for message catalogues, simply pass the --disable-nls +option to configure. N.B. This is not related to man's ability to display +NLS manual pages, support for which is compiled in by default. + +Running make. + + * RUN `make' to compile man-db with the set of translations chosen + when running `./configure'. + +Sort out the man-db configuration file. + + * RUN `./src/man -l man/man5/manpath.5' from the root of this + distribution to read the man-db configuration file details. + + * EDIT `./src/man_db.conf' to your local requirements. + +Install the package. + + * (gain superuser privileges for the rest of the steps) + + * RUN `make install' to install the utilities and manual pages. + +Initialise the `index' databases for all manpaths marked as global in the +man-db configuration file. + + * RUN `mandb' (This step is equivalent to running straycats and + makewhatis too). + +The following steps are optional / dependent on local conventions. + + * ACKNOWLEDGE any warnings emitted by mandb. Bogus manual pages + are not included in the database and may be a waste of space. + Those pages without correctly formatted `whatis' lines are + included, but will have a whatis entry of "(unknown)" + + * CD tools and RUN `mkcatdirs -t' to see if you have all of the + required cat directories. `mkcatdirs' without an option will + display a usage message. + + * CD tools and RUN `checkman' with an argument of colon separated + manual page hierarchies to cross check for duplicated manual + pages. If no argument is given, your default $MANPATH will be + used. + + The output of checkman may be piped into a file and used as an + argument to `rm', the `is newer than' messages are directed to + standard error. e.g. `checkman > dups' + + If you are confident that the duplicates found are indeed + duplicates, you can back them up and delete them to save space. + + At this point, running checkman again may yield further duplicates + that were ignored the first time. + + * RUN `catman' with appropriate options to create any/all cat files + that you would like pre-formatted. + + +Multiple build directories +========================== + +It is possible to build man-db in a directory other than the directory +containing this file (and all of the program sources). This is particularly +useful if compiling on multiple architectures or testing various +configuration options as only a single copy of the sources is required. + +To enable this support, simply change directory to where you would like to +build the package and run the configure program in this directory +*from there*. Further information about this support can be found in the +generic install document `docs/INSTALL.autoconf'. + + +Makefile targets and variables +============================== + +The standard GNU Makefile targets: all, install, uninstall, mostlyclean, +clean, distclean, realclean and TAGS are available in every Makefile- +supported directory. In addition, the master Makefile has the dist target +to create a compressed and tarred distribution file. + +During the configuration process, `configure' sets the installation +variables, `prefix' and `exec_prefix'. These are then used to form other +variables such as `bindir' and `sysconfdir'. To change any of these or +other standard GNU install variables dynamically, issue the `make' command +with variable expressions as arguments, eg. `make prefix=/usr/local/packages' + +N.B. If prefix=/usr (either statically or dynamically), then sysconfdir=/etc +instead of the usual $(prefix)/etc. To force sysconfdir to be /usr/etc, set +it on the make command line. + + +Default preprocessors +===================== + +man-db uses a manual page directed preprocessor system, that is, each manual +page may request preprocessing by a selection of preprocessors. Some +systems' manual pages do not come with this information built in. In such +circumstances, it is advisable to set a default list of preprocessors that +each manual page should be passed through, so that those requiring special +processing are readable. To achieve this, set DEFAULT_MANROFFSEQ (found in +include/manconfig.h) to the appropriate preprocessor string, after running +configure, but prior to compilation. This is not necessary for the +following systems whose default preprocessing requirements are known. + + Known not to require DEFAULT_MANROFFSEQ: + Linux, SunOS + Known to require #define DEFAULT_MANROFFSEQ "t": + Ultrix + Known to require #define DEFAULT_MANROFFSEQ "te": + HP-UX, OSF/1 + +If unsure of the default preprocessors required by a system, the standard +system's man(1) manual page may provide an answer. + + +Contacting the maintainer +========================= + +The current maintainer of man-db is Colin Watson . +Please feel free to contact me with any queries or problems you may have. +You can report bugs here: + + https://savannah.nongnu.org/bugs/?group=man-db diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 0000000..a5e4ac6 --- /dev/null +++ b/aclocal.m4 @@ -0,0 +1,1747 @@ +# generated automatically by aclocal 1.16.3 -*- Autoconf -*- + +# Copyright (C) 1996-2020 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, +[m4_warning([this file was generated for autoconf 2.69. +You have another version of autoconf.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE.

Here's a very brief +guide on how to get started. + + +Directory layout +---------------- + +The source tree looks something like this, ignoring some directories added +by autoconf, automake, gettext, and gnulib: + + docs/ + Assorted documentation. + man/ + Man pages for man-db's programs. + manual/ + The man-db manual, written in troff. + include/ + Header files used throughout the package. + lib/ + Basic library files, some of which supplement inadequate C libraries on + various systems and some of which implement utility functions used + throughout the package. + libdb/ + The database access library. Code outside this directory should not know + about specific back-end database implementations. + src/ + Source code to the man-db programs themselves. + tools/ + Miscellaneous add-on scripts. + po/ + Translations. + + +Coding style +------------ + +Each indent is a single tab. Brace style is K&R. Each function name is +separated from the following opening parenthesis by a single space. (All +this is almost certainly controversial somewhere, but it's as close as +you'll get to a prevailing style here.) + +Keep all code within 80 columns (counting tabs as 8). This can sometimes be +a little tight with the deep indent; think of it as a useful discipline to +stop indentation levels getting out of hand. :-) (This rule is currently +broken for argp option declarations, for the sake of other kinds of +readability. This may change.) + +If you're editing existing code and it differs from any of the above, stick +with whatever the existing code does. Likewise, if in doubt, find similar +code and use its style. Maintaining a consistent style is important for +general readability, and is more important than any individual point. It's +also the easiest way to avoid long and tedious debates about "correct" +style. + + +Facilities and portability +-------------------------- + +man-db uses Gnulib to provide portability support and utility functions +common to many GNU packages (although man-db is not itself a GNU package), +while the lib/ directory provides some other utility functions specific to +man-db. Please make use of these facilities where available. In particular, +there are various functions beginning with 'x' which check the return values +from the system's memory allocation calls, which you should use instead of +their non-'x' siblings. + +appendstr() provides manageable string concatenation. Use it where +appropriate. Remember to terminate its argument list with a NULL. In many +cases, xasprintf() from Gnulib may be more readable. + +If you're calling any of the is*() or to*() functions in , please +do so via the CTYPE() macro in include/manconfig.h to ensure that the +argument type is correct. + +You may assume C89 (e.g. no need to support K&R-style function definitions), +but please do not assume C99 (e.g. do not use nested functions or // +comments). However, it's OK to use C99 runtime facilities that are provided +by Gnulib, such as . + + +Testing +------- + +There is a small test suite in src/tests/, as well as basic tests in man/ to +ensure that man-db's own manual pages format without errors. Tests for new +bug fixes are not *required*, but are generally a good idea. + +Various test library facilities are available in src/tests/testlib.sh. Feel +free to extend this as necessary. + + +Things to do +------------ + +docs/TODO has a number of outstanding projects. Things near the bottom are +usually more detailed and accurate. + +The Debian bug tracking system has a number of outstanding reports on man-db +at . + +Much of the work needed on man-db is for maintainability. Patches that take +difficult-to-understand code with hairy memory allocation and replace it +with clean, obvious, and reliable code are most welcome, especially if they +introduce new abstractions which are of more general use. The replacement of +splitline() with the page_description interface is a good example of this. + +Work on porting to platforms other than GNU/Linux is welcome. It's been a +while since serious effort in that direction has been invested in man-db. +Most of the code should be quite portable, but the occasional teething +problem would not be a surprise. + + +Sending patches +--------------- + +Please send patches in unified diff format (use 'git diff', or GNU diff with +the -u option) to man-db-devel@nongnu.org. See +https://lists.nongnu.org/mailman/listinfo/man-db-devel for subscription +instructions. + + +Revision control +---------------- + +man-db is revision-controlled using git (https://git-scm.com/). The archive +may be fetched from here using 'git clone': + + https://git.savannah.gnu.org/git/man-db.git + +To browse changes or source code in a web browser, use this URL instead: + + https://git.savannah.gnu.org/cgit/man-db.git + +Members of the man-db project on Savannah can commit directly by pushing to +this URL: + + ssh://git.sv.gnu.org/srv/git/man-db.git + +Otherwise, since git is a distributed revision control system, you are of +course free to make and publish branches which can then be merged into the +main tree. See the git documentation for further details. + +Generated files should be added to .gitignore and should not be committed to +revision control. + + +Release process +--------------- + +1. Update the AC_INIT version number in configure.ac to "x.y.z-pre1". Commit + and tag. + +2. Run ./release.sh to produce a preliminary tarball for translators. This + doesn't have to be particularly well-tested or even compile; it's only + there to provide context for po/man-db.pot. Send this to the Translation + Project robot. + +3. Wait a couple of weeks for a reasonable number of translation updates to + arrive. During this time, test until your eyeballs fall out, but try to + avoid changing any translated messages. + +4. Ensure that NEWS and docs/man-db.lsm are up to date. Commit. + +5. Update the AC_INIT version number and 'date' in configure.ac, but don't + commit yet. + +6. Run ./release.sh, which will spit out a tarball. Test it. + +7. Commit the changes from step 5. + +8. Tag everything. + +9. Run ./release.sh. This is the distribution tarball; test it as thoroughly + as you can. + +10. Upload the tarball to Savannah. + +11. Announce to wherever seems appropriate. diff --git a/docs/INSTALL.autoconf b/docs/INSTALL.autoconf new file mode 100644 index 0000000..8865734 --- /dev/null +++ b/docs/INSTALL.autoconf @@ -0,0 +1,368 @@ +Installation Instructions +************************* + + Copyright (C) 1994-1996, 1999-2002, 2004-2016 Free Software +Foundation, Inc. + + Copying and distribution of this file, with or without modification, +are permitted in any medium without royalty provided the copyright +notice and this notice are preserved. This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same time stamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options. Run +'configure --help' for more details. diff --git a/docs/INSTALL.quick b/docs/INSTALL.quick new file mode 100644 index 0000000..dd9410d --- /dev/null +++ b/docs/INSTALL.quick @@ -0,0 +1,45 @@ +Full installation details are included in ../README.
