After the change of d6a5cc665a
we have a lot of code points in FcBlanks. doing the linear search
on the array isn't comfortable anymore.
So re-implementing FcBlanksIsMember() to use the binary search.
Figuring out how much improved after this change depends on
how many fonts proceed with fc-cache say though, it's about 20 times
faster here on testing. which sounds good enough for
improvement.
Assuming that d_name is the last member of struct dirent.
In POSIX, the maximum length of d_name is defined as NAME_MAX
or FILENAME_MAX though, that assumption may be wrong on some
platforms where defines d_name as the flexible array member
and allocate the minimum memory to store d_name.
Patch from Raimund Steger
A while back we removed Apple Roman encoding support. This broke
symbol fonts (Wingdings, etc) because those fonts come with two
cmaps:
1) platform=1,encoding=0, aka Apple Roman, which maps identity,
2) platform=3,encoding=0, aka MS Symbol font
Now, the reason the Apple Roman removal "broke" these fonts is
obvious, and for the better: these fonts were mapping ASCII and
other Latin chars to symbols.
The reason the fonts didn't work anymore, however, is that we were
mishandling the MS symbol-font cmaps. In their modern incarnation
they are like regular non-symbol-font cmap that map PUA codepoints
to symbols. We want to expose those as such. Hence, this change
just removes the special-handling for that.
Now, the reason this confusion happened, if I was to guess, is either
that FreeType docs are wrong saying that FT_ENCODING_MS_SYMBOL is
the "Microsoft Symbol encoding, used to encode mathematical symbols":
http://www.kostis.net/charsets/symbol.htm
or maybe it started that way, but turned into also mapping MS symbol-
font cmaps, which is a completely different thing. At any rate, I
don't know if there are any fonts that use this thing these days, but
the code here didn't seem to produce charset for any font. By now I'm
convinced that this change is the Right Thing to do. The MS Symbol
thing was called AdobeSymbol in our code by the way.
This fixes the much-reported bug that windings, etc are not usable
with recent fontconfig:
https://bugs.freedesktop.org/show_bug.cgi?id=58641
Now I see PUA mappings reported for Wingdings.
This also fixes:
Bug 48947 - Drop the non-Unicode cmap support gradually
https://bugs.freedesktop.org/show_bug.cgi?id=48947
since the AdobeSymbol was the last non-Unicode cmap we were
trying to parse (very incorrectly).
Lots of code around this change can be simplified. I'll push those
out (including removing the table itself) in subsequent changes.
All color fonts are designed to be scaled, even if they only have
bitmap strikes. Client is responsible to scale the bitmaps. This
is in constrast to non-color strikes...
Clients can still use FC_OUTLINE to distinguish bitmap vs outline
fonts. Previously FC_OUTLINE and FC_SCALABLE always had the same
value. Now FC_SCALABLE is set to (FC_OUTLINE || FC_COLOR).
Fixes:
https://bugs.freedesktop.org/show_bug.cgi?id=87122
This reverts commit a5a384c5ff.
I don't remember what I had in mind for "We will use this property later.", but
the change was wrong. If a font pattern doesn't have any value for element,
it must be interpretted as "it matches any value perfectly. And "perfectly"
must have a score of 0 for that to happen.
This was actually affecting bitmap fonts (in a bad way), as the change made
an outline font to always be preferred over a (otherwise equal) bitmap font,
even for the exact size of the bitmap font. That probably was never noticed
by anyone, but with the font range support this has become clear (and worked
around by Akira). To clean that up, I'm reverting this so I can land the
rest of patches for bug 80873.
https://bugs.freedesktop.org/show_bug.cgi?id=80873#c10
Previously, if the patten didn't request, eg, style, then the style
and stylelang were fully copied from the font, even though the pattern
had a stylelang. Eg:
$ fc-match 'Apple Color Emoji:stylelang=en'
Apple Color Emoji.ttf: "Apple Color Emoji" "標準體"
This change both fixes that and makes the code much more readable. Now:
$ fc-match 'Apple Color Emoji:stylelang=en'
Apple Color Emoji.ttf: "Apple Color Emoji" "Regular"
iconv support was turned off by default in f30a5d76.
Some fonts, like Apple Color Emoji, only have their English
name in a MacRoman entry. As such, decode MacRoman ourselves.
Previous format was unusable. New format is ranges of hex values.
To choose space character and Latin capital letters for example:
$ fc-pattern ':charset=20 41-5a'
Pattern has 1 elts (size 16)
charset:
0000: 00000000 00000001 07fffffe 00000000 00000000 00000000 00000000 00000000
(s)
It was added without proper measurement and a fuzzy possible
use-case (font servers) in mind, but reality check shows that
this significantly slows down caching. As such, deprecate it
and do NOT compute hash during caching.
Makes caching two to three times faster (ignoring the 2 second
delay in fc-cache).
This is more robust but introduces a small change in behavior:
For .pcf.gz fonts, the new code calculates the hash of the uncompressed
font data whereas the original code was calculating the hash of the
compressed data.
No big deal IMO.
FcTypeVoid is likely to happen when 'lang' and 'charset'
is deleted by 'delete' or 'delete_all' mode in edit.
Without this change, any modification on them are simply
ignored.
This is useful to make a lot of changes, particularly
when one wants to add a few and delete a lot say.
This feature requires the FreeType 2.5.1 or later at the build time.
Besides <range> element allows <double> elements with this changes.
This may breaks the cache but not bumping in this change sets at this moment.
please be aware if you want to try it and run fc-cache before/after to
avoid the weird thing against it.
Let me show it with an example.
Currently:
$ fc-match symbol
symbol.ttf: "Symbol" "Regular"
$ fc-match symbol --sort | head -n 1
Symbol.pfb: "Symbol" "Regular"
$ fc-match symbol --sort --all | head -n 1
symbol.ttf: "Symbol" "Regular"
I want to make sure the above three commands all return the same font.
Ie. I want to make sure FcFontMatch() always returns the first font
from FcFontSort(). As such, never trim first font.

Patch from Maxim Iorsh
Add two edit mode, "delete" and "delete_all".
what values are being deleted depends on <test> as documented.
if the target object is same to what is tested, matching value there
will be deleted. otherwise all of values in the object will be deleted.
so this would means both edit mode will not take any expressions.
e.g.
Given that the testing is always true here, the following rules:
<match>
<test name="foo" compare="eq">
<string>bar</string>
</test>
<edit name="foo" mode="delete"/>
</match>
will removes "bar" string from "foo" object. and:
<match>
<test name="foo" compare="eq">
<string>foo</string>
</test>
<edit name="bar" mode="delete"/>
</match>
will removes all of values in "bar" object.
This changes allows to have multiple mathcing rules in one <match> block
in the same order.
After this changes, the following thing will works as two matching rules:
<match>
<!-- rule 1 -->
<test name="family" compare="eq">
<string>foo</string>
</test>
<edit name="foo" mode="append">
<string>foo</string>
</edit>
<!-- rule 2 -->
<test name="foo" compare="eq">
<string>foo</string>
</test>
<edit name="foo" mode="append">
<string>bar</string>
</edit>
</match>
In FcStrListCreate() we were increasing reference count of set,
however, if set had a const reference (which is the case for list

Here's the valgrind error, which took me quite a few hours of

Thread test is running happily now. Will add the test in a moment.
We used to have a shared-str pool. Removed to make thread-safety
work easier. My measurements show that the extra overhead is not
significant by any means.
These never worked as intended. The problem is, if Fontconfig tries to
read config files when these new types / constants are not registered,
it errs. As a result, no defined types / constants are usable from
config files. Which makes these really useless. Xft was the only user
of this API and even there it's not really used. Just kill it.
One inch closer to thread-safety since we can fix the object-type hash
table at compile time.
The type will be resolved at runtime...
For example, we can do this now without getting a warning:
<match target="font">
<test name="scalable" compare="eq">
<bool>false</bool>
</test>
<edit name="pixelsizefixupfactor" mode="assign">
<divide>
<name target="pattern">pixelsize</name>
<name target="font" >pixelsize</name>
</divide>
</edit>
<edit name="matrix" mode="assign">

</times>
</edit>
<edit name="size" mode="assign">
<divide>
<name>size</name>
<name>pixelsizefixupfactor</name>
</divide>
</edit>
</match>
Previously the last edit was generating:
Fontconfig warning: "/home/behdad/.local/etc/fonts/conf.d/00-scale-bitmap-fonts.conf", line 29: saw unknown, expected number
Based on idea from Raimund Steger.
For example, one can do something like this:
<match target="font">
<test name="scalable" compare="eq">
<bool>false</bool>
</test>
<edit name="pixelsizefixupfactor" mode="assign">
<divide>
<name target="pattern">pixelsize</name>

Previously a <matrix> element could only accept four <double> literals.
It now accepts full expressions, which can in turn poke into the
pattern, do math, etc.
After 7587d1c99d applied, family,
style, and fullname is localized against current locale or lang
if any though, the string in other languages were dropped from
the pattern. this caused unexpected mismatch on the target="font"
rules.
This fix adds other strings at the end of the list.
X_OK checking was added back in 8ae1e3d5dc

Windows does not update mtime of directory on FAT filesystem when
file is added to it or removed from it. Fontconfig uses mtime of
directory to check cache file aging and hence fails to detect
newly added or recently removed files.
This changeset detects FAT filesystem (currently implemented for
Linux) and adds generating checksum of directory entries instead
of using mtime which guarantees proper cache rebuild.
For non-FAT filesystems this patch adds single syscall per directory
which is negligeable overhead.

the old directories are still in the configuration files for

Add a new attribute `ignore-blanks' to <test>.

on comparison. This takes effects for compare="eq" or "not_eq" only.
Also changed the behavior of the comparison on <alias> too.
This patch isn't really tested as I don't have such a machine, but I

Add "namelang" object to obtain the localized name in the font regardless

This is a reasonably conservative increase in the number of buckets in the hash
table to 251. After FcInit(), there are 240 shared strings in use on my system
(from configuration files I assume). The hash value is stored in each link in
the chains so comparison are actually not very expensive. This change should
reduce the average length of chains by a factor of 8. With the reference
counted strings, it should keep the average length of chains to about 2. The
number of buckets is prime so as not to rely too much on the quality of the
hash function.

Patch from Karl Tomlinson
In the previous code, the result of 'result' in the argument for
FcFontSetSort() and FcFontSetMatch() wasn't predictable and not reliable to
check if the return value is valid or not. this change is to ensure if it's
performed successfully.
$< isn't supported in BSD make say. $(RM) is pre-defined in GNU make
though, not in BSD make say. so changed to check on configure if it's
pre-defined by make, otherwise set the appropriate command to $(RM).
This would be a workaround until it has the certain pre-defined value.
When adding new functions, if the actual definition doesn't match the
header (say due to a typo), the regeneration of the internal headers
get confused and output bad cpp logic. This causes gcc to barf due
to mismatched #ifdef/#endif. Which is a pain to figure out due to
the sheer voulme of generated code.
So tweak the makealias script to detect this case and error out.
While we're here, improve the cpp output a bit to indent, include
comments, and merge similar ifdef blocks.

I broke FcFontSort() language handling at the end of 2008 with this
commit: c7641f28
G-d knows how many of the lang-matching bugs in bugzilla will be
fixed by this changed...
I'm really sorry, everyone!
- Do not throw away FC_FILE in FcNameUnparse
- Update the builtin "fclist" format to remove FC_FILE properly instead
- Switch fc-list to use FcPatternFormat()
Note that I had previously broken fc-list and it was not showing the
file name anymore. No one noticed that it seems! Now fixed.
Do not remove blacklisted fonts during cache generation. We already
apply the blacklist when reading the caches. The idea always has been
that the config should not affect caches built, although that design
was tarnished with the introduction of target="scan" configurations.
The syntax to add any characters to the charset table looks like:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="charset" mode="assign">
<plus>
<name>charset</name>
<charset>
<int>0x3220</int> <!-- PARENTHESIZED IDEOGRAPH ONE -->
</charset>
</plus>
</edit>
</match>
To remove any characters from the charset table:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="charset" mode="assign">
<minus>
<name>charset</name>
<charset>
<int>0x06CC</int> <!-- ARABIC LETTER FARSI YEH -->
<int>0x06D2</int> <!-- ARABIC LETTER YEH BARREE -->
<int>0x06D3</int> <!-- ARABIC LETTER YEH BARREE WITH HAMZA ABOVE -->
</charset>
</minus>
</edit>
</match>
You could also use the range element for convenience:
...
<charset>
<int>0x06CC</int> <!-- ARABIC LETTER FARSI YEH -->
<range>
<int>0x06D2</int> <!-- ARABIC LETTER YEH BARREE -->
<int>0x06D3</int> <!-- ARABIC LETTER YEH BARREE WITH HAMZA ABOVE -->
</range>
</charset>
...
The OT spec says:
"When building a Unicode font for Windows, the platform ID should be 3 and the
encoding ID should be 1. When building a symbol font for Windows, the platform
ID should be 3 and the encoding ID should be 0."
We were ignoring the SYMBOL_CS entry before. It's UTF-16/UCS-2 like the
UNICODE_CS.
Also, always use UTF-16BE instead of UCS-2BE. The conversion was doing
UTF-16BE anyway.
Last night in between my dreams I also noticed that we support Unicode
values up to 0x01000000 and not 0x00100000 which I thought before.
This covers the entire Unicode range.
Protect cache against future expansions of FcLangSet (adding new
orth files). Previously, doing so could change the size of
that struct. Indeed, that happened between 2.6.0 and 2.7.3, causing
crashes. Unfortunately, sizeof(FcLangSet) was not checked in fcarch.c.
This changes FcLangSet code to be able to cope with struct size changes.
And change cache format, hence bumping from 2 to 3.
Before a NULL config was passed down adn essentially FcFileScan was
equivalent to FcFreeTypeQuery. Now fc-scan tool correctly applies
the configuration to the scanned patterns.
The East Asian double-byte codepages have characters with backslash as
the second byte, so we must use _mbsrchr() instead of strrchr() when
looking at pathnames in the system codepage.
Must not call FcStrFree() on a value returned by
FcStrBufDoneStatic(). In the Windows code don't bother with dynamic
allocation, just use a local buffer.
Fontconfig assigns an index number to each language it knows about.
The index is used to index a bit in FcLangSet language map. The bit
map is stored in the cache.
Previously fc-lang simply sorted the list of languages and assigned
them an index starting from zero. Net effect is that whenever new
orth files were added, all the FcLangSet info in the cache files would
become invalid. This was causing weird bugs like this one:
https://bugzilla.redhat.com/show_bug.cgi?id=490888
With this commit we fix the index assigned to each language. The index
will be based on the order the orth files are passed to fc-lang. As a
result all orth files are explicitly listed in Makefile.am now, and
new additions should be made to the end of the list. The list is made
to reflect the sorted list of orthographies from 2.6.0 released followed
by new additions since.
This fixes the stability problem. Needless to say, recreating caches
is necessary before any new orthography is recognized in existing fonts,
but at least the existing caches are still valid and don't cause bugs
like the above.
The format '%{[]family,familylang{expr}}' expands expr once for the first
value of family and familylang, then for the second, etc, until both lists
are exhausted.
The '%{=unparse}' format expands to the FcNameUnparse() result on the
pattern. Need to add '%{=verbose}' for FcPatternPrint() output but
need to change that function to output to a string first.
Also added the '%{=fclist}' and '%{=fcmatch}' which format like the
default format of fc-list and fc-match respectively.
The format '%{family|delete( )}' expands to family values with space removed.
The format '%{family|translate( ,-)}' expands to family values with space
replaced by dash. Multiple chars are supported, like tr(1).
The format '%{family|escape(\\ )}' expands to family values with space
escaped using backslash.
The format '%{family|downcase}' for example prints the lowercase of
the family element. Three converters are defined right now:
'downcase', 'basename', and 'dirname'.
The conditional '%{?elt1,elt2,!elt3{expr1}{expr2}}' will evaluate
expr1 if elt1 and elt2 exist in pattern and elt3 doesn't exist, and
expr2 otherwise. The '{expr2}' part is optional.
The filtering, '%{+elt1,elt2,elt3{subexpr}}' will evaluate subexpr
with a pattern only having the listed elements from the surrounding
pattern.
The deletion, '%{-elt1,elt2,elt3{subexpr}}' will evaluate subexpr
with a the surrounding pattern sans the listed elements.
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.
To only work on writable charsets. Also, return a bool indicating whether
the merge changed the charset.
Also changes the implementation of FcCharSetMerge and FcCharSetIsSubset
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.
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.
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.
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.
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.
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
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).
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.
The fact that we now drop final slashes from all filenames without
checking that the file name represents a directory may surprise some,
but it doesn't bother me really.
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.
It seems indices in _FcMatchers array are slightly mixed up, MATCH_DECORATIVE
should be 10, not 11.
And MATCH_RASTERIZER_INDEX should be 13, not 12, right?
Libtool-2.2 introduces new restrictions. So now it does not allow LT_*
variables as it includes marcros:
m4_pattern_forbid([^_?LT_[A-Z_]+$])
Rename the LT_ variables to LIBT_ to work around this restriction.
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.
If the /usr/bin/head program is missing or unusable, or if an unusable head
program is listed first in the PATH, fontconfig fails to build
using "sed -n 1p" instead of "head -1" would be a suitable workaround.
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.
David Turner has modified FreeType to be able to render sub-pixel decimated
glyphs using different methods of filtering. Fontconfig needs new
configurables to support selecting these new filtering options. A patch
follows that would correspond to one available for Cairo in bug 10301.
Bitmap-only TrueType fonts without a glyf table will not load a glyph when
FT_LOAD_NO_SCALE is set. Work around this by identifying TrueType fonts that have no
glyphs and select a single strike to measure the glyph map with.
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".
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.
This reverts commit b607922909.

Xft still uses the macros that are in fcprivate.h. Document those macros and
include fcprivate.h in the published header files.
These two names are typos of the correct names. Instead of simply changing
them, the correct thing to do is leave them in the library, add the correct
functions and mark them as deprecated so any source packages will be updated.
This requires bumping the minor version of the library (for adding APIs)
instead of bumping the major version of the library (for removing APIs).
