Only sort the result array if it contains more than one element, making the mansearch() function easier to read for human auditors. No functional change on OpenBSD. As observed by Mark Millard <marklmi at yahoo dot com>, neither the latest version of POSIX 2008 nor C11 defines what qsort(3) should do for base == NULL && nmemb == 0. My impression is it is indeed undefined behaviour because the standards say that base shall point to an array, NULL does not point to an array, and while there is special wording saying that compar() shall not be called if nmemb == 0, i fail to see any similar wording stating that base shall not be accessed if nmemb == 0. Consequently, this patch is also likely to improve standard conformance and portability. Minor issue found by Stefan Esser <se at FreeBSD> with UBSAN. He sent a patch to bugs@, but my patch differs in a minor way.

In man(1) mode, i.e. when asking for a single manual page by name, prefer file name matches over .Dt/.TH matches over first NAME matches over later NAME matches, but do not change the ordering for apropos(1) nor for man -a. This reverts main.c rev. 1.213 and mansearch.h rev. 1.23 and includes a partial revert of mansearch.c rev. 1.62. Regression reported by Lorenzo Beretta <loreb at github> as part of https://github.com/void-linux/void-packages/issues/9868 .

Cleanup, no functional change: Split the top level parser interface out of the utility header mandoc.h, into a new header mandoc_parse.h, for use in the main program and in the main parser only. Move enum mandoc_os into roff.h because struct roff_man is the place where it is stored. This allows removal of mandoc.h from seven files in low-level parsers and in formatters.

In apropos(1) output, stop sorting .Nm search results by name priorities (bits). The obscure feature wasn't documented and merely confused people - for example Edward Tomasz Napierala <trasz at FreeBSD>, see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227408. Smaller patch provided by Yuri Pankov <yuripv at FreeBSD>, but i'm also retiring the now unused "bits" member from struct manpage. Simplification is good.

Improve POSIX compliance by making case-insensitive extended regular expressions the default in man(1) -k searches, also matching what the man-db package used by many Linux distributions does. Originally requested by Wolfram Schneider <wosch at FreeBSD> via Yuri Pankov <yuripv at FreeBSD>. Feedback and OK cheloha@, and no objections when shown on tech@. Thanks to cheloha@ for pointing out that POSIX requires this behaviour and for the suggestion to explicitly say that *extended* regular expressions are used here. While here, unify spelling of case-[in]sensitive, fix a typo, update the EXAMPLES, and add a STANDARDS section.

No longer use names that only occur in the SYNOPSIS section as names for man(1) lookup. For OpenBSD base and Xenocara, that functionality was never intended to be required, and i just fixed the last handful of offenders using it - not counting the horribly ill-designed interfaces engine(3) and lh_new(3) which are impossible to properly document in the first place. Of course, apropos(1) and whatis(1) continue to use SYNOPSIS .Nm, .Fn, and .Fo macros, so "man -k ENGINE_get_load_privkey_function" still works. This change also gets rid of a few bogus warnings "cross reference to self" which actually are *not* to self, like in yp(8). This former functionality was intended to help third-party software in the ports tree and on non-OpenBSD systems containing manual pages with incomplete or corrupt NAME sections. But it turned out it did more harm than good, and caused more confusion than relief, specifically for third party manuals and for maintainers of mandoc-portable on other operating systems. So kill it. Problems reported, among others, by Yuri Pankov (illumos). OK jmc@

Prefer arch-dependent over arch-independent pages if the name priority, the section number, and all names match. Changes little on installed systems except the ordering of apropos(1) results, because we install base and Xenocara manuals in different trees, but fixes lookup of pages like apm(4) vs. apm(4/amd64) in man.cgi(8). Issue discovered by martian67 on freenode and reported via tj@.

Basic reporting of .Xrs to manual pages that don't exist in the base system, inspired by mdoclint(1). We are able to do this because (1) the -mdoc parser, the -Tlint validator, and the man(1) manual page lookup code are all in the same program and (2) the mandoc.db(5) database format allows fast lookup. Feedback from, previous versions tested by, and OK jmc@. A few features will be added to this in the tree, step by step.

Finally use __progname, err(3) and warn(3). That's more readable and less error-prone than fumbling around with argv[0], fprintf(3), strerror(3), perror(3), and exit(3). It also shortens the code by 50 lines. It's a bad idea to boycott good interfaces merely because standards committees ignore them. Instead, it's the job of the portable distribution to provide compatibility modules for archaic systems (like commercial Solaris) that still don't have them. Actually, the compat code for the portable distribution already exists and will be committed right after this.

Make the man(1) and apropos(1) options -s and -S much less expensive:
Do not append an SQL clause looking into the large "keys" table.
Instead, filter the result of the SQL query in buildnames() where
equivalent data from the much smaller "mlinks" table is already
available for free.
This is relevant because man(1) uses the equivalent of "-S ${MACHINE}"
by default since main.c rev. 1.122, to make sure that manuals for
the current architecture are shown. With many ports installed, this
patch can speed up man(1) by a factor of more than a hundred.

In man(1) mode, change to the right directory before starting the parser, just like traditional man(1) does, such that .so links have a chance to work. After this point, we don't need the current directory for anything else before exit, so we don't need to worry about getting back and we can safely ignore failure. This lets man(1) find more Xenocara manuals, but not all of them yet. Other issues remain that need to be fixed, too.

Add an implementation of man(1) into the /usr/bin/mandoc binary and provide a unified set of command line options for mandoc(1), man(1), apropos(1), and whatis(1), each option doing the same for all four. Not adding any completely new options, only extending exiting ones from one tool to the others. New options are: * apropos & whatis -acfkw (in the past, these were man(1) only) * apropos & whatis -a -IOTW (in the past, mandoc(1) only) * mandoc -ac (in the past, man(1) only) * man -IOTW (in the past, mandoc(1) only) Before we can decide whether or not we want to replace src/usr.bin/man with this implementation, considerable bugfixing, testing, and performance measurements are needed, which i'd rather do in the tree than outside. Note that these bugs only affect the new man(1) mode, existing mandoc(1), apropos(1), and whatis(1) is fine. The new functionality in mandoc(1), apropos(1), and whatis(1) is fully enabled. To play with the new man(1), you can try: # mv /usr/bin/man /usr/bin/oman # ln -s /usr/bin/mandoc /usr/bin/man Positive feedback about the general direction from sthen@ and jmc@, and deraadt@ is not against it.

At the end of mansearch(), fchdir() back to where we started from; this is cleaner and helps to not scatter gmon.out files all over the place when profiling.

Further apropos(1) speed optimization was trickier than anticipated. Contrary to what i initially thought, almost all time is now spent inside sqlite3(3) routines, and i found no easy way calling less of them. However, sqlite(3) spends substantial time in malloc(3), and even more (twice that) in its immediate malloc wrapper, sqlite3MemMalloc(), keeping track of all individual malloc chunk sizes. Typically about 90% of the malloced memory is used for purposes of the pagecache. By providing an mmap(3) MAP_ANON SQLITE_CONFIG_PAGECACHE, execution time decreases by 20-25% for simple (Nd and/or Nm) queries, 10-20% for non-NAME queries, and even apropos(1) resident memory size as reported by top(1) decreases by 20% for simple and by 60% for non-NAME queries. The new function, mansearch_setup(), spends no measurable time. The pagesize chosen is optimal: * Substantially smaller pages yield no gain at all. * Larger pages provide no additional benefit and just waste memory. The chosen number of pages in the cache is a compromise: * For simple queries, a handful of pages would suffice to get the full speed effect, at an apropos(1) resident memory size of about 2.0 MB. * For non-NAME queries, a large pagecache with 2k pages (2.5 MB) might gain a few more percent in speed, but at the expense of doubling the apropos(1) resident memory size for *all* queries. * The chosen number of 256 pages (330 kB) allows nearly full speed gain for all queries at the price of a 15% resident memory size increase.

Next speed optimization step for the new apropos(1). Split manual names out of the common "keys" table into their own "names" table. This reduces standard apropos(1) search times (i.e. searching for names and descriptions only) by typically about 70% for the full /usr/share/man database. (Yes, that multiplies with the previous optimization step, so both together have reduced search times by a factor of more than six. I'm not done yet, expect more to come.) Even with the minimal databases built with makewhatis(8) -Q, this step still reduces search times by 15-20%. For both cases, database sizes and build times hardly change (+/-2%).

After careful gprof(1)ing of the new apropos(1), move the descriptions back from the keys table to the mpages table: I found a good way to still use them in searches, without complication of the code. On my notebook, this reduces typical apropos(1) search times by about 40%, it reduces /usr/share/man database size by 6% in makewhatis(8) -Q mode and by 2% in standard mode (less overhead storing pointers to mpages), and it doesn't measurably change database build times (may even be going down by a percent or so because less data is being copied around in ohashes).

Properly initialize malloc(3)ed memory. With this bug fix, partly unitialized memory could sometimes be returned, sometimes causing crashes by bogus free(3)s in apropos(1).

The files mandoc.c and mandoc.h contained both specialised low-level functions used for multiple languages (mdoc, man, roff), for example mandoc_escape(), mandoc_getarg(), mandoc_eos(), and generic auxiliary functions. Split the auxiliaries out into their own file and header. While here, do some #include cleanup.

Reimplement apropos -s NUM -S ARCH EXPR by internally converting it to apropos \( EXPR \) -a 'sec~^NUM$' -a 'arch~^(ARCH|any)$' in preparation for removal of sec and arch from the mpage table.

Experimental feature to let apropos(1) show different keys than .Nd. This really takes us beyond what grep -R /usr/*/man/ can do because now you can search for pages by *one* criterion and then display the contents of *another* macro from those pages, like in $ apropos -O Ox Fa~wchar to get an impression how long wide character handling is available.

Replace the Berkeley-DB based mandocdb(8) by an SQLite3-based version, aiming for more flexible development and optimization options. Kristaps started this during the summer 2012, i did some very heavy bugfixing during t2k13 and finally, during the last few days, got it to a state where it is ripe for in-tree development. Beware, neither the user interfaces nor the database formats are expected to be stable just yet. Will not be installed or activated until further discussion. No functional change to mandoc(1). "As long as it remains off until we decide the cost, fine." deraadt@
