Pagesize no longer matters in architecture decisions, the entire cache file
is mmaped into the library. However, lots of intptr_t values are in use now,
so that value is important.
fc-lang now requires fcserialize.c, which has been added to the repository.
Replace all of the bank/id pairs with simple offsets, recode several
data structures to always use offsets inside the library to avoid
conditional paths. Exposed data structures use pointers to hold offsets,
setting the low bit to distinguish between offset and pointer.
Use offset-based data structures for lang charset encodings; eliminates
separate data structure format for that file.
Much testing will be needed; offsets are likely not detected everywhere in
the library yet.
(numbers_count); didn't strip duplicate numbers (langBankNumbers); and
leafidx_offset and numbers_offset in fcLangCharSets are wrong.
Removed leafidx_count and numbers_count since they are the same and
replaced them with offset_count.

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.
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.
clean up .spec file; perhaps this will be useful to somebody...
Update to 2.2.93
Make 'scanopen' static so GCC doesn't whine about lacking prototype
Add WARN_CFLAGS to pass -W flags for GCC systems
Change various char types around to match across function calls. Fixed bug
in using available_sizes[i].height which is in pixels, not 64ths of a
pixel.
but there are still failures long into the process dealing with docs
(as always).
The big changes here are mostly to make $(srcdir) != "." work correctly,
fixing the docbook related sections and fc-lang were particularily
tricky. Docbook refuses to load system entities from anywhere other
than where the original .sgml file was located, so no luck looking in
"." for the configure-generated version.sgml and confdir.sgml files.
fc-lang needed help finding .orth files; added a -d option to set the
directory as the least evil of many options.
Now to go use a faster machine and try and wring out the last issues.
