Behdad Esfahbod c493c3b770 [fcformat] Add support for width modifiers
One can do '%30{family}' for example.  Or '%-30{family}' for the
left-aligned version.

Behdad Esfahbod b697fa2523 [cache] After writing cache to file, update the internal copy to reflect this
Only do it for small caches though.  For large cache we'd better off loading
the cache file again, mmap()ing it.

Based on patch from Diego Santa Cruz.

Behdad Esfahbod e62058abb9 [win32] Fix usage of GetFullPathName()
Diego Santa Cruz pointed out that we are using that API wrongly.
The forth argument is a pointer to a pointer.  Turns out we don't
need that arugment and it accepts NULL, so just pass that.

Behdad Esfahbod 6d764a3f9b [fcmatch] Move FcFontSetMatch() functionality into FcFontSetMatchInternal()
Except for the final FcFontRenderPrepare().  This way we have more
flexibility to do caching in FcFontMatch() while leaving FcFontSetMatch()
intact.

Behdad Esfahbod a5a384c5ff [fcmatch] When matching, reserve score 0 for when elements don't exist
Previously an index j was added to element score to prefer matches earlier
in the value list to the later ones.  This index started from 0, meaning
that the score zero could be generated for the first element.  By starting
j from one, scores for when the element exists in both pattern and font
can never be zero.  The score zero is reserved for when the element is
NOT available in both font and pattern.  We will use this property later.

This shouldn't change matching much.  The only difference I can think of
is that if a font family exists both as a bitmap font and a scalable
version, and when requesting it at the size of the bitmap version,
previously the font returned was nondeterministic.  Now the scalable
version will always be preferred.
2009-02-13 16:54:05 -08:00
Behdad Esfahbod c7641f2872 [fcmatch] Use larger multipliers to enforce order
Previously the matcher multiplied comparison results by 100 and added
index value to it.  With long lists of families (lots of aliases),
reaching 100 is not that hard.  That could result in a non-match early
in the list to be preferred over a match late in the list.  Changing
the multiplier from 100 to 1000 should fix that.

To keep things relatively in order, the lang multiplier is changed
from 1000 to 10000.

Behdad Esfahbod a291cfc710 Fix comparison of family names to ignore leading space properly
Previously fc-match "xxx,nazli" matched Nazli, but "xxx, nazli" didn't.
This was because of a bug in FcCompareFamily's short-circuit check
that forgot to ignore spaces.

Behdad Esfahbod f9806ab4b9 Remove special-casing of FC_FILE in FcPatternPrint()
I can't understand why the special case is needed.  Indeed, removing it
does not make any difference in the "fc-match --verbose" output, and
that's the only time fc-match uses FcPatternPrint.

Behdad Esfahbod 8ae1e3d5dc Explicitly chmod() directories (bug #18934)
Two changes:

  - after mkdir(), we immediately chmod(), such that we are not affected
    by stupid umask's.

  - if a directory we want to use is not writable but exists, we try a
    chmod on it.  This is to recover from stupid umask's having affected
    us with older versions.

Behdad Esfahbod 799691c901 Don't leak FcValues string loaded through fcxml.c (#17661)
Patch from Caolan McNamara.
2009-02-13 16:54:00 -08:00
Chris Wilson 311da2316f Reduce number of allocations during FcSortWalk().
The current behaviour of FcSortWalk() is to create a new FcCharSet on
each iteration that is the union of the previous iteration with the next
FcCharSet in the font set. This causes the existing FcCharSet to be
reproduced in its entirety and then allocates fresh leaves for the new
FcCharSet. In essence the number of allocations is quadratic wrt the
number of fonts required.

By introducing a new method for merging a new FcCharSet with an existing
one we can change the behaviour to be effectively linear with the number
of fonts - allocating no more leaves than necessary to cover all the
fonts in the set.

For example, profiling 'gedit UTF-8-demo.txt'
    Allocator		    nAllocs	    nBytes
Before:
    FcCharSetFindLeafCreate 62886	    2012352
    FcCharSetPutLeaf        9361	    11441108
After:
    FcCharSetFindLeafCreate 1940	    62080
    FcCharSetPutLeaf        281		    190336

The savings are even more significant for applications like firefox-3.0b5
which need to switch between large number of fonts.
Before:
    FcCharSetFindLeafCreate 4461192	    142758144
    FcCharSetPutLeaf	    1124536	    451574172
After:
    FcCharSetFindLeafCreate 80359	    2571488
    FcCharSetPutLeaf	    18940	    9720522

Out of interest, the next most frequent allocations are
    FcPatternObjectAddWithBinding 526029    10520580
    tt_face_load_eblc	    42103	    2529892

Behdad Esfahbod 03dcaaa08f Document when config can be NULL (#17105)
Note that this also fixes a bug with FcFontList() where previously
it was NOT checking whether the config is up-to-date.  May want to
keep the old behavior and document that ScanInterval is essentially
unused internally (FcFontSetList uses it, but we can remove that
too).

Behdad Esfahbod 2987409853 Implement fc-list --verbose (#13015)
A private FcObjectGetSet() is implemented that provides an
FcObjectSet of all registered elements.  FcFontSetList() is
then modified to use the object set from FcObjectGetSet() if
provided object-set is NULL.

Alternatively FcObjectGetSet() can be made public.  In that
case fc-list can use that as a base if --verbose is included,
and also add any elements provided by the user (though that has
no effect, as all elements from the cache are already registered).
Currently fc-list ignores user-provided elements if --verbose
is specified.

Sayamindu Dasgupta ad3fc66791 FcConfigUptoDate breaks if directory mtime is in the future. Bug 14424.
At OLPC, we came across a bug where the Browse activity (based on xulrunner)
took 100% CPU after an upgrade/. It turns out the Mozilla uses
FcConfigUptoDate() to check if new fonts have been added to the system, and
this function was always returning FcFalse since we have the mtimes of some
font directories set in the future. The attached patch makes
FcConfigUptoDate() print a warning and return FcTrue if mtime of directories
are in the future.

Keith Packard 3322ca8553 Use of ":=" in src/Makefile.am is unportable (bug 14420)
Building 2.5.91 on Solaris with the native make(1) yields

...
Making all in src
make: Fatal error in reader: Makefile, line 313: Unexpected end of line seen
Current working directory /tmp/fontconfig-2.5.91/src
*** Error code 1

This is due to the following line (src/Makefile.am:143):

    CLEANFILES := $(ALIAS_FILES)

Changing that to a standard assignment ("=") fixes the problem.

I believe the ":=" is a typo. ALIAS_FILES is just a statically assigned
variable; it's not like evaluating it more than once would be a problem.

Dennis Schridde 6d65081e35 Proper config path for static libraries in win32
Since fontconfig didn't have special handling for paths in static Windows
libraries, I've created a patch which should fix this.

Basically it does this:
fccfg.c:
If fontconfig_path was uninitialised it tries to get the directory the exe is
in and uses a fonts/ dir inside that.
fcxml.c:
In case the fonts.conf lists a <dir>CUSTOMFONTDIR</dir>, it searches for a
fonts/ directory where the exe is located.

Hongbo Zhao 0f7870887a Not_contain should use strstr, not strcmp on strings. (bug 13632)
For Version 2.5.0, (same for previous version 2.4.2), in source file fccfg.c,
on line 700,

Original:
      ret = FcStrCmpIgnoreCase (left.u.s, right.u.s) == 0;

Should change to:
      ret = FcStrStrIgnoreCase (left.u.s, right.u.s) == 0;

I think this is just a mistake when copy-n-paste similar codes in the same
function. Apparently, return for "Not_contain" should be just the inverse of
"Contain", not the same as "Equal".
2007-12-12 21:48:10 -08:00
Tor Lillqvist 8a3dc4880c Workaround for stat() brokenness in Microsoft's C library (bug 8526)
Fix a couple of longstanding problems with fontconfig on Windows that
manifest themselves especially in GIMP. The root cause to the problems is in
Microsoft's incredibly stupid stat() implementation. Basically, stat()
returns wrong timestamp fields for files on NTFS filesystems on machines
that use automatic DST switching.

See for instance http://bugzilla.gnome.org/show_bug.cgi?id=154968 and
http://www.codeproject.com/datetime/dstbugs.asp

As fccache.c now looks at more fields in the stat struct I fill in them all.
I noticed that fstat() is used only on a fd just after opening it, so on
Win32 I just call my stat() replacement before opening instead...
Implementing a good replacement for fstat() would be harder because the code
in fccache.c wants to compare inode numbers. There are no (readily
accessible) inode numbers on Win32, so I fake it with the hash of the full
file name, in the case as it is on disk. And fstat() doesn't know the full
file name, so it would be rather hard to come up with a inode number to
identify the file.

The patch also adds similar handling for the cache directory as for the fonts
directory: If a cachedir element in fonts.conf contains the magic string
"WINDOWSTEMPDIR_FONTCONFIG_CACHE" it is replaced at runtime with a path under
the machine's (or user's) temp folder as returned by GetTempPath(). I don't
want to hardcode any pathnames in a fonts.conf intended to be distributed to
end-users, most of which who wouldn't know how to edit it anyway. And
requiring an installer to edit it gets complicated.

These two names are typos of the correct names. Instead of simply changing

This requires bumping the minor version of the library (for adding APIs)
instead of bumping the major version of the library (for removing APIs).

Keith Packard 96925b99c0 Eliminate relocations for glyph name table.
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.

Keith Packard bc5e8adb4d Must not insert cache into hash table before completely validating.
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.

Keith Packard e85789a997 Place language name in constant array instead of pointer.
Constant char array of 8 bytes is the same size as a pointer plus a short
string, so this actually saves memory and eliminates a pile of relocations.

Mike FABIAN 07e646cc84 Avoid crashes if config files contain junk.
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.

Keith Packard 238489030a Don't use X_OK bit when checking for writable directories (bug 12438)
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.

Keith Packard f7da903d37 Make FC_FULLNAME include all fullname entries, elide nothing. [bug 12827]
The old policy of eliding fullname entries which matched FC_FAMILY or

font foundry set as the fullname of the font. Hiding information is not
helpful.

Keith Packard 144ca87831 Comment about mmaping cache files was misleading. 2007-10-18 04:29:13 -07:00
Keith Packard db6f19f13b Store font directory mtime in cache file.
Instead of relying on mtime ordering between a directory and its associated
cache file, write the directory mtime into the cache file itself. This makes
cache file checks more reliable across file systems.

This change is made in a way that old programs can use new cache files, but
new programs will need new cache files.

Stephan Kulow 9b74b78fe8 Make FcPatternDuplicate copy the binding instead of always using Strong.
I noticed that Qt always uses a different font than fc-match advertises.
Debugging the issue, I found that a call that looks pretty innocent is

semantic of the match: FcPatternDuplicate.

Keith Packard 64d7e303df Warn (and recover) from config file without <cachedir> elements.
When updating from older fontconfig versions, if the config file
is not replaced, it will not contain <cachedir> elements. Lacking these,
fontconfig has no place to store cached font information and cannot operate
reasonably.

Add code to check and see if the loaded configuration has no cache
directories, and if so, warn the user and add both the default system cache
directory and the normal per-user cache directory.
2006-12-02 12:14:49 -08:00
Keith Packard 253ec7609c Use explicit platform/nameid order when scanning ttf files.
Instead of accepting whatever order names appear in the font file,
use an explicit ordering for both platform and nameid.

Platforms are high precedence than nameids.

The platform order is:

	microsoft, apple unicode, macintosh, (other)

The family nameid order is:

	preferred family, font family

The fullname nameid order is:

	mac full name, full name

The style nameid order is

	preferred subfamily, font subfamily

This will change the names visible to users in various application UIs, but
should not change how existing font names are matched as all names remain
present in the resulting database. The hope is that family names will, in
general, be less ambiguous. Testing here shows that commercial fonts
have longer names now while DejaVu has a shorter family name, and moves more
of the font description to the style name.

Han-Wen Nienhuys 1de7a4cc09 FcStrCanonFileName buggy for mingw. (bug 8311)
FcStrCanonFileName checks whether s[0] == '/', and recurses if not.

This only works on POSIX. On dos, this crashes with a stack overflow.

The patch attached splits this functionality in two functions
(FcStrCanonAbsoluteFilename) and uses GetFullPathName on windows to get an
absolute path.  It also fixes a number of other issues. With this patch,
LilyPond actually produces output on Windows.

Keith Packard 17389539a0 Make cache reference counting more efficient.
Eliminate need to reference cache object once per cached font, instead

efficient enough for use.
2006-09-04 22:26:24 -07:00
Keith Packard 9e612141df Reference count cache objects.
Caches contain patterns and character sets which are reference counted and
visible to applications. Reference count the underlying cache object so that
it stays around until all reference objects are no longer in use.

This is less efficient than just leaving all caches around forever, but does
avoid eternal size increases in case applications ever bother to actually
look for changes in the font configuration.
2006-09-04 22:20:25 -07:00
Keith Packard 8fe2104a1e Leave cache files mapped permanently.
Without reference counting on cache objects, there's no way to know when
an application is finished using objects pulled from the cache. Until some
kinf of cache reference counting can be done, leave all cache objects mapped
for the life of the library (until FcFini is called). To mitigate the cost
of this, ensure that each instance of a cache file is mapped only once.

Borrowing header stuff written for cairo, fontconfig now exposes in the

Keith Packard c2c6976d1a Add FcMatchScan to resolve Delicious font matching issues (bug #6769)
The Delicious family includes one named Delicious Heavy, a bold variant
which is unfortunately marked as having normal weight. Because the family
name is 'Delicious', fontconfig accidentally selects this font instead of
the normal weight variant. The fix here rewrites the scanned data by running
the scanned pattern through a new substitution sequence tagged with
<match target=scan>; a sample for the Delicious family is included to
demonstrate how it works (and fix Delicious at the same time).

Also added was a new match predicate -- the 'decorative' predicate which is
automatically detected in fonts by searching style names for key decorative
phrases like SmallCaps, Shadow, Embosed and Antiqua. Suggestions for
additional decorative key words are welcome. This should have little effect
on font matching except when two fonts share the same characteristics except
for this value.

Validate cache contents and skip broken caches, looking down cache path for
valid ones.

Every time a directory is scanned, it will be written to a cache file if
possible, so fc-cache doesn't need to re-write the cache file. This makes
detecting when the cache was generated a bit tricky, so we guess that if the
cache wasn't valid before running and is valid afterwards, the cache file
was written.

Also, allow empty charsets to be serialized with null leaves/numbers.

Keith Packard 7ce1967331 Rework cache files to use offsets for all data structures.
Replace all of the bank/id pairs with simple offsets, recode several
data structures to always use offsets inside the library to avoid

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.
