some manuals containing overzealous escaping in their NAME section.
|
|
For .Sh, i wasn't even needed at all.
For .Dd, .Nm, and .Os, use the new mdoc_deroff() instead.
This gets rid of the last limited-size static buffers in this file,
hence eliminates the last explicit MANDOCERR_MEM throwers here,
and it shortens the code by 50 lines.

instead use the .Nd content recursively.
Improves a couple of index entries in base.
|
|
entries for .Nd in mandocdb(8), instead use the macro content
recursively. This improves indexing of more than 200 manuals
in Xenocara, i.e. more than 15%, in particular GL and some Xkb.
|
|
|
|
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.

|
macros to be cleared during .Dd and .TH because clearing them at that
point defeats the purpose of backup implementations provided in the
manual page itself, some of which _do_ work with mandoc(1).
While here, add the new .%C macro to the list to be cleared.

This doesn't affect /usr/share/man, but improves /usr/X11R6/man:
* Eliminates multiple apropos(1) output for such pages.
* Reduces X11R6 database size from 450 kB to 240 kB (-47%).
* Reduces X11R6 database build time from 1.68s to 1.00s (-40%).

single .so request, do not read the file pointed to, but instead
let mparse_result() provide the file name pointed to as a return
value. To be used by makewhatis(8) in the future.

them an "options" argument, replacing the existing "inttype" and
"quick" arguments, preparing for a future MPARSE_SO option.
Store this argument in struct mparse and struct roff, replacing the
existing "inttype", "parsetype", and "quick" members.
No functional change except one tiny cosmetic fix in roff_TH().

permission on the databases, as requested by espie@ quite some time ago.
But make sure to not slow database generation down when you do have write
permission, and to not delay error reporting in -Q mode.

length even when they are breakable. Before this, a line containing N
breakable hyphens could get up to N characters wider than the right margin
in -Tutf8 output mode.
Issue reported by tedu@ on bugs@.

instead of the man_node line member. This is required to preserve
line breaks contained in user-defined macros called in .nf mode.
Found in a code audit triggered by fixing a similar issue in .TP.
|
|
use the MAN_LINE flag instead of the man_node line member.
This is required such that user-defined macros wrapping .TP work correctly.
Issue found by Havard Eidnes in Tcl_NewStringObj(3), reported via
the NetBSD bug tracking system and Thomas Klausner <wiz at NetBSD>.

* Support string comparisons.
* Support negation not only for numerical, but for all conditions.
* Switch the `o' condition from false to true.
* Handle the `c', `d', and `r' conditions as false for now.
* Use int for boolean data instead of rolling our own "enum roffrule";
needed such that we can use the standard ! and == operators.
Havard Eidnes reported via the NetBSD bug tracking system that some
Tcl*(3) manuals need this, and Thomas Klausner <wiz at NetBSD>
forwarded the report to me. This doesn't make the crazy Tcl*(3)
macrology maze happy yet, but brings us a bit closer.

when found on a macro line, does not close a conditional block.
The companion function roff_cond_text() already did this correctly,
but make the code more readable without functional change.
While here, report the correct column number in related error messages.

1. Handle more than one `\}' on macro lines, as it was already done
for text lines.
2. Do not treat `\}' as a macro invocation after a dot at the beginning
of a line. That allows more than one `\}' to work on lines starting
with `.\}'. It also simplifies the code.
3. Do not complain about characters following `\}'. Those are not lost,
but handled normally both on text and macro lines.

have to render as non-combining accents; if you want combining accents,
you have to explicitly specify them using the Unicode character numbers
for combining accents, or you can use character escape sequences for
accented characters. This lets mandoc behave like groff.
Additionally, both the Ossanna/Kernighan/Ritter troff manual and
the GNU troff manual say that \' and \` are equivalent to \(aa and
\(ga, respectively, so do the same for these. This mitigates issues
with man(7) code autogenerated by texinfo2man(1), which mistranslates
TeX ` and ' to \` and \' instead of \(oq and \(cq as reported by
sthen@ and as analyzed by bentley@.

page template contained in groff_mdoc(7), catch up with our own stuff.
In particular, allow ERRORS in section 4 and DIAGNOSTICS in section 9.

fixes a crash reported by blambert@ and a few other, similar ones

We even parse and ignore the .ad request (adjustment mode),
and it doesn't make sense to more prominently warn about
temporary than about permanent adjustment changes.
Request found by naddy@ in xloadimage(1) and by juanfra@ in racket(1).

Missing feature found by jca@ in ratpoison(1).
The ratpoison(1) manual still doesn't work because it uses .shift
and .while, too (apparently, ratpoison is so complex that it
needs a Turing-complete language to even format its manual :-).

In particular, this improves handling of the pod2man(1) preamble;
for examples of the effect, see some author names in perlthrtut(1).

somewhat similar to what mdoc_term.c already does for -Tascii.

documented in the Ossanna-Kernighan-Ritter troff manual
and also supported by groff.

This doesn't hurt normal manual display
and makes the mandocdb(8) database more useful.

Reduces database size by ~0.5%, and by ~1.5% with -Q.

i need that for debugging, in particular to be used with -t.
To be able to do so, provide a global table of key names, for reuse.

mask size. No functional change.
This shrinks the standard /usr/share/man database by 7%, now at 10.3x
the size of whatis.db, and with -Q even by 11%, now at 3.0x of whatis.db.
Now i'm out of ideas to easily shrink the size of the database.

They are completely unused, and i cannot imagine what they *could*
ever be used for; but apparently, they are expensive to generate.
Standard DB build time goes down by 10%, now at 1.9x of makewhatis.
Standard DB size goes down by 4%, now at 11x of makewhatis.
DB build time with -Q goes down by 15%, now at 0.28x of makewhatis.
DB size with -Q goes down by 3%, now at 3.35x of makewhatis.
Optimization found somewhere above the Southern Balochistan desert,

creating an index for the keys table on apropos(1) search times;
apparently, adding that index was premature optimization in the first
place; so, stop adding that index.
Its root gone, the following evil is reduced (/usr/share/man on my notebook)
- DB build time with -Q goes down by 15%, now at 1/3 of makewhatis
- DB size with -Q goes down by 35%, now at 3.5x of makewhatis
- full DB build time goes down by 12%, now at 2.1x of makewhatis
- full DB size goes down by 42%, now at 11.5x of makewhatis

over and over again for each manual; found with gprof(1).
Speeds up mandocdb(8) -Q by 3%, now at 39.5% of makewhatis(8).
|
|
Another 10% speedup for mandocdb(8) -Q, and even 3% without -Q.
With -Q, we are now at 41% of the time required by makewhatis(8).
Do not copy predefined strings into the dynamic string table, just
leave them in their own static table and use that one as a fallback
at lookup time. This saves us copying and deleting them for each manual.
No functional change.
|
|
In -Q mode, refrain form validating and normalizing the format
of the date given in .Dd or .TH, as it won't be used anyway.
For /usr/share/man, mandocdb -Q now takes 45% of the time of makewhatis(8).
|
|
For /usr/share/man, we only need 56% of the time of makewhatis(8) now.
In groff, user-defined macros clashing with mdoc(7) or man(7)
standard macros are cleared when parsing the .Dd or .TH macro,
respectively. Of course, we continue doing that in standard mode
to assure full groff bug compatibility.
However, in -Q mode, full groff bug compatibility makes no sense
when it's unreasonably expensive, so skip this step in -Q mode.
Real-world manuals hardly ever redefine standard macros,
that's terrible style, and if they do, it's pointless to do so
before .Dd or .TH because it has no effect. Even if someone does,
it's extremely unlikely to break mandocdb(8) -Q parsing because we
abort the parse sequence after the NAME section, anyway.
So if you manually redefine .Sh, .Nm, .Nd, or .SH in a way that doesn't
work at all and rely on .Dd or .TH to fix it up for you, your broken
manual will no longer get a perfect apropos(1) entry until you re-run
mandocdb(8) without -Q. It think that consequence is acceptable
in order to get a 25% speedup for everyone else.

only sync to disk one single time when all data is ready.
Rebuild times for /usr/share/man/mandoc.db shrink on my notebook:
In standard mode from 45 seconds to 11 seconds (75% reduction)
In -Q mode from 25 seconds to 3.1 seconds (87% reduction)
For comparison: makewhatis(8): 4.2 seconds
That is, in -Q mode, we are now *faster* than the existing makewhatis(8),
and careful profiling shows there is still a lot of room for improval.

It was broken by recent optimizations.
|
|
The concept of an index file is gone since the switch to SQLite.
No functional change.
|
|
The contents can easily be reconstructed from sec, arch, name, form.
Shrinks the database by another 3% in standard mode and 9% in -Q mode.
