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.
'object' table (strings pointed to by FcPatternElt->object and used as
keys) and loading of object table from cache file if more strings are
present in cache file than in current version of fontconfig. Hash the
object table in memory.
and distribute bytes for each directory from a single malloc for that
directory. Store pointers as differences between the data pointed to
and the pointer's address (s_off = s - v). Don't serialize data
structures that never actually get serialized. Separate strings used
for keys from strings used for values (in FcPatternElt and FcValue,
respectively). Bump FC_CACHE_VERSION to 2.
cache. Add *Read and *Write procedures which mmap in and write out the
fontconfig data structures to disk. Currently, create cache in /tmp,
with different sections for each architecture (as returned by uname's
.machine field. Run the fc-cache binary to create a new cache file;
fontconfig then uses this cache file on subsequent runs, saving lots of
memory. Also fixes a few bugs and leaks.
ids can be positive (for static strings) or negative (for dynamic
strings). Static strings belong to a single buffer, while dynamic
strings are independently allocated.
This patch allows the fundamental fontconfig data structures to be
serialized. I've converted everything from FcPattern down to be able to
use *Ptr objects, which can be either static or dynamic (using a union
which either contains a pointer or an index) and replaced storage of
pointers in the heap with the appropriate *Ptr object. I then changed
all writes of pointers to the heap with a *CreateDynamic call, which
creates a dynamic Ptr object pointing to the same object as before.
This way, the fundamental fontconfig semantics should be unchanged; I
did not have to change external signatures this way, although I did
change some internal signatures. When given a *Ptr object, just run *U
to get back to a normal pointer; it gives the right answer regardless
of whether we're using static or dynamic storage.
I've also implemented a Fc*Serialize call. Calling FcFontSetSerialize
converts the dynamic FcFontSets contained in the config object to
static FcFontSets and also converts its dependencies (e.g. everything
you'd need to write to disk) to static objects. Note that you have to
call Fc*PrepareSerialize first; this call will count the number of
objects that actually needs to be allocated, so that we can avoid
realloc. The Fc*Serialize calls then check the static pointers for
nullness, and allocate the buffers if necessary. I've tested the
execution of fc-list and fc-match after Fc*Serialize and they appear to
work the same way.
memoize strings and share a single copy for all uses. Note that this could
be improved further by using statically allocated blocks and gluing
multiple strings together, but I'm basically lazy. In my environment
with 800 font files, I get a savings of about 90KB.
Add detection of iconv
Document new selectfont elements
Switch to UTF-8 in comment
Add fullname, and family/style/fullname language entries
Respect selectfont/*/glob
Add support for selectfont
Add multi-lingual family/style/fullname support
Expose FcListPatternMatchAny (which selectfont/*/pattern uses)
Add new FcPatternRemove/FcPatternAppend. FcObjectStaticName stores computed
pattern element names which are required to be static.
