FcCharSetSerialize was computing the offset to the unserialized leaf,
which left it pointing at random data when the cache was reloaded.
fc-cat has been updated to work with the new cache structure.
Various debug messages extended to help diagnose serialization errors.
Make fontconfig compile under MinGW:
1) remove unneeded #includes;
2) make use of mmap and sysconf conditional;
3) replace rand_r by srand/rand if needed;
4) use chsize instead of ftruncate; and
5) update libtool exports file
Minor change to global cache file format to fix fc-cat bug reported by
Frederic Crozat, and buglet with not globally caching directories with
zero fonts cached.
helps make fontconfig FHS-compliant, but requires that all caches get
rebuilt.
Also, autogen.sh now needs the additional parameter
--localstatedir=/var.
fully-qualified font names for clients' benefit. Clients only pay for
the font names once they request the FC_FILE property from an
FcPattern, but the font name is malloc'd at that point (i.e. not
mmapped: that's impossible, since it may vary between machines.)
Clients do have to pay for a copy of the path name per cache file.
Note that FcPatternGetString now does some rewriting if you ask for an
FC_FILE, appending the pathname as appropriate.
fonts.cache-1 files (e.g. for grepping and validation of the mmap
codepath), as per James Cloos' request.
Remove done 'TODO' comment.
Updates for development release 2.3.90.
