Package: fontconfig
Version: 2.6.0-1
Severity: wishlist
So I just installed a bunch of fonts and BOY IS IT SLOW.
There are two things going on.
(1) "Updating fontconfig cache for /usr/share/fonts/..."
(2) "Regenerating fonts cache"
#2 is done independently by a very large number of font packages calling
HOME=/root fc-cache -f -v 1>/var/log/fontconfig.log 2>&1
#1 is done by a large number of packages calling
defoma-font --reregister-all /etc/defoma/hints/XXX.hints
which ends up calling /usr/share/defoma/scripts/fontconfig.defoma, which
calls
fc-cache -f
and
fc-cache -s *TWICE*.
So fc-cache can be run four or more times *per font installation*. And
it actually needs to be run precisely once per apt-get run.
The obvious way to fix this is dpkg triggers. fontconfig should have a
trigger on any change to /usr/share/fonts which causes it to regenerate
the cache. fontconfig.triggers would look like this:
interest /usr/share/fonts
And fontconfig.postinst would be patched like this:
--- fontconfig.postinst 2008-09-14 12:52:55.000000000 -0400
+++ fontconfig.postinst.new 2008-09-14 12:54:27.000000000 -0400

done
printf "done.\n"
fi
+fi
+if [ "$1" = "configure" ] || [ "$1" = "triggered" ]
# Force regeneration of all fontconfig cache files.
mkdir -p /var/cache/fontconfig
printf "Regenerating fonts cache... "
This would allow bugs to be filed on all packages (except fontconfig and
defoma) which run fc-cache in postinst, to just remove those explicit
invocations. That would speed things up quite a bit. This should be
done *now*.
---
The interaction with defoma is much trickier and a much larger problem.
First of all, defoma *could* be invoked on a nonstandard directory,
which would require a hand run of fc-cache. It could also be invoked by
hand for locally installed fonts in /usr/local or the user's home
directory.
Second, the current fontconfig.defoma script does something very ugly in
its 'term' subroutine. It runs fc-cache, then blows away
/var/lib/defoma/fontconfig.d/fonts.conf, then runs fc-list to determine
the accessible font directories "without" defoma, then rebuilds
/var/lib/defoma/fontconfig.d/fonts.conf, then runs fc-cache AGAIN.
This is hideous and very, very slow. I don't see any way to avoid this
when using locally installed fonts, for which it is pretty much doing
the right thing. There's got to be some way to bypass this for packaged
fonts, however. I figure we can simply detect whether we're dealing
with a subdirectory of /usr/share/fonts, and assume that we're in a
'packaged' situation then, and if not, assume that we're not. I almost
finished a patch to do exactly this, but I hit a problem.
The problem is that the rebuilding of
/var/lib/defoma/fontconfig.d/fonts.conf *both* rebuilds the directory
list (which we can just skip for fonts in the standard directories under
/usr/share/fonts), *and* the aliases and substitutes lists (which I
believe we *can't* skip -- if we can skip them, tell me and I'll attach
the patch for fontconfig.defoma). I'm not currently seeing how to
preserve the directory list while rebuilding the aliases and substitutes
lists.
If you could break the file into two pieces, one for the directories and
one for the aliases and substitutions, it would be quite straightforward
to rewrite fontconfig.defoma to skip all the tedious cache rebuilds when
it's dealing with a font in /usr/share/fonts. (All such fonts should be
handled by dpkg, and therefore we can rely on the trigger to rebuild the
cache.)
