FcStrCopyFilename constructs a canonical path for any argument, including
expanding leading ~ and editing '.' and '..' elements out of the resulting
path.
FcConfigUptoDate only checks whether files have been modified since the
configuration was created. Any changes to the configuration through the API
since then are not considered.
fcprivate.h was supposed to extend the fontconfig API for the various
fontconfig utilities. Instead, just have those utilities use the internal
fcint.h header file (which they already do), removing fcprivate.h from the
installation and hence from the defacto public API.
If the provided style value doesn't match any available font, fall back to
using the weight and slant values by ensuring that those are in the pattern.
This adds the missing orth files for Ndebele (South) (nr), Northern Sotho
(nso), Swati (ss) and Southern Sotho (st). It also fixes the Tswana (tn)
orth file.
If the generated header files are included in the distribution, a build
outside of the source directory will use them. For machine-specific files,
this generates the wrong result (fcarch.h). Leaving them out of the
distribution forces them to be built.
Glyph names (now used only for dingbats) were using many relocations,
causing startup latency plus per-process memory usage. Replace pointers with
table indices, shrinking table size and elimninating relocations.
The cache was inserted into the hash table before the timestamps in the
cache were verified; if that verification failed, an extra pointer to the
now freed cache would be left in the hash table. FcFini would fail an
assertion as a result.
If ~/.fonts.conf contains:
<edit mode="assign_replace" name="spacing">
<int>mono</int>
</edit>
fontconfig crashes:
mfabian@magellan:~$ fc-match sans
Fontconfig error: "~/.fonts.conf", line 46: "mono": not a valid
integer
セグメンテーション違反です (core dumped)
mfabian@magellan:~$
Of course the above is nonsense, “mono” is no valid integer indeed.
But I think nevertheless fontconfig should not crash in that case.
The problem was caused by partially truncated expression trees caused by
parse errors -- typechecking these walked the tree without verifying the
integrity of the structure. Of course, the whole tree will be discarded
shortly after being loaded as it contained an error.
Old cache file versions, or corrupted cache files should be removed when
cleaning cache directories with fc-cache. This only affects filenames which
match the fontconfig cache file format, so other files will be left alone.
Some mingw versions have broken X_OK checking; instead of trying to work
around this in a system-depedent manner, simply don't bother checking for
X_OK along with W_OK as such cases are expected to be mistakes, and not
sensible access control.
fc-cache would say 'skipping: %d fonts, %d dirs' or 'caching: %d fonts, %d
dirs', which could easily mislead the user. Add 'existing cache is valid' or
'new cache contents' to these messages to explain what it is doing.
This call was followed by a call to stat(2) which provided the necessary
information. This call to access(2) was necessary when cache files were
stored in the font directory as that would check for write permission
correctly.
