FcStrCanonFilename eliminates ./ and ../ elements from pathnames through
simple string editing. Also, relative path names are fixed by prepending the
current working directory.
With the removal of the in-directory cache files, and the addition of
per-user cache directories, there is no longer any reason to preserve the
giant global cache file. Eliminating of this unifies the cache structure
and simplifies the overall caching strategies greatly.
Normalized directory names offer protection against looped directory trees
but cost enormous numbers of system calls (stat per file in the hierarchy).
Also, cache file directory name contents are validated each time the
directory is modified, don't re-validate every time the cache file is loaded
with an access and stat call.
Save subdirectory names in cache files to save time. This completely
restores the original fontconfig API, BTW. Note that directories
without fonts don't get a cache file; but then how many files would it
have in that directory...
The global cache now uses the same mmap-based cache infrastructure as the
per-directory caches. Furthermore, the global cache is automatically
updated (if possible) whenever fontconfig is used. Rip out remnants of
the old cache infrastructure.
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.
wherever the X fonts are located).
Document new <include>directory-name</include> semantics
add <include ignore_missing="yes">conf.d</include>
Add selectfont to ignore bitmap fonts, add comment for selectfont which
accepts bitmap fonts.
Allow <include> configuration elements to reference directories. Parse and
load all files of the form [0-9]* in sorted order.
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.
