This is a bugfix release for the 2.3 series, which brings considerable
improvements for b/w rasterizing of hinted TrueType fonts at
small sizes. All users should upgrade.
changes:
-important bugfixes
-improved CID support
There was an ABI breakage between 2.3.7 and 2.3.8 which was reverted
in 2.3.9. The public 'PS_FontInfoRec' structure was expanded and
then shrunk. Applications compiled against 2.3.8 should work fine
with 2.3.9. Applications compiled against the new 2.3.9 can
theoretically exhibit problems if run against a 2.3.8 binary, if
some PS_FontInfo stuff is used. See the freetype release notes
for details. I didn't find any suspects for now. If one is found,
it should be changed to require 2.3.9, and PKGREV bumped.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
changes:
-improvements for fonts in an SFNT wrapper (used on Mac)
-FT_MulFix is now an inlined function; by default, assembler code
is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX
and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more
-handling of `tricky' fonts has been generalized and changed slightly
-API additions
-bugfixes
X.Org found in NetBSD-current.
Thanks a lot to all who helped, especially Matthias Scheler who did
repeated tests on Mac OS X and older versions of NetBSD to make sure the
support for those platforms wouldn't be broken (or at least, not fatally,
as I would still expect a few hiccups here and there, because there is
only so much one can test in such limited time).
On the infrastructure side, this branch brings pkgconfig-builtin.mk, in
order to write very easily new builtin.mk files. It can actually handle
more than just pkgconfig files, but it will provide a version if it finds
such a file. x11.builtin.mk has also been made more useful and now all
existing (and future!) native-X11-related builtin.mk files should include
it.
This is a bugfix release for the 2.3 series which provides some important
fixes for bugs which were introduced in version 2.3.6. Additionally, native
bytecode hinting for TrueType fonts has been improved.
* src/cff/cffobjs.c (cff_face_init): Compute final
`dict->units_per_em' value before assigning it to
`cffface->units_per_EM'. Otherwise, CFFs without subfonts are be
scaled incorrectly if the font matrix is non-standard. This fixes
Savannah bug #23630
This fixes the problem that text set in a font embedded as type 1C subset
was rendered unreadably small.
bump PKGREVISION
This fixes some integer overflow/memory corruption/heap overflow
security problems: CVE-2008-1806, CVE-2008-1807, CVE-2008-1808
other changes:
-new function `FT_Get_CID_Registry_Ordering_Supplement' gives
access to those fields in a CID-keyed font
-code to validate the new `MATH' OpenType table
-API for cmap 14 support
-A new face flag FT_FACE_FLAG_CID_KEYED
-misc bugfixes and other improvements
changes:
-Some subglyphs in TrueType fonts were handled incorrectly due to
a missing graphics state reinitialization.
-Large .Z files (as distributed with some X11 packages) weren't
handled correctly, making FreeType increase the heap stack in an
endless loop.
-A large number of bugs have been fixed to avoid crashes and
endless loops with invalid fonts.
-API extensions for caching, TT handling
-autohinter improvement for non-Latin scripts
-Support for Windows FON files in PE format
* src/bdf/bdflib.c (setsbit, sbitset): Handle values >= 128
gracefully.
(_bdf_set_default_spacing): Increase `name' buffer size to 256 and
issue an error for longer names.
(_bdf_parse_glyphs): Limit allowed number of glyphs in font to the
number of code points in Unicode.
This fixes CVE-2007-1351.
This switches to the new stable branch. There are too many API additions
and other changes to list here -- see the changelog.
Some notes:
-There is an unpatented hinter built in per default. The "truetype"
pkgsrc option does still enable another one -- the documentation here
is inconsistent, so I've left this alone for now. I couldn't find
a visible effect with my fonts on my display.
-New pkgsrc option "subpixel". Enables subpixel rendering for LCDs.
Not default because there are patent issues.
-There is sone strange effect of the CONFIG_SHELL environment valiable
on the "configure" script. Worked around this by overriding the
env var in the pkg Makefile. Someone understanding shell quoting might
be able to locate the underlying problem.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
pkg-config file.
This fixes problem where non-pkgsrc software builds using this info
can also find the ft2build.h header. (Not noticed in pkgsrc itself
because that include file is already known.)
This is also done in upstream version in the 2.2 release candidates.
The commit log message upstream is:
builds/unix/freetype2.in (CFlags): Add missing directory.
Bump PKGREVISION.
I. IMPORTANT BUG FIXES
- The size comparison for BDF and PCF files could fail sometimes.
- Some CFF files were still not loaded correctly. Patch from
Derek Noonburg.
- The stroker still had some serious bugs.
- FreeType didn't properly parse empty Type 1 glyphs.
- An unbound dynamic buffer growth was fixed in the PFR loader.
- Several bugs have been fixed in the cache sub-system.
- The auto-hinter didn't work properly for fonts without a Unicode
charmap -- it even refused to load the glyphs.
II. IMPORTANT CHANGES
- Many fixes have been applied to drastically reduce the amount of
heap memory used by FreeType, especially when using
memory-mapped font files (which is the default on Unix systems
which support them).
- The auto-hinter has been replaced with a new module, called the
`auto-fitter'. It consumes less memory than its predecessor,
and it is prepared to support non-latin scripts better in next
releases.
- George Williams contributed code to read kerning data from PFM
files.
III. MISCELLANEOUS
- The BDF driver no longer converts all returned bitmaps with a
depth of 2bpp or 4bpp to a depth of 8bpp.
- A new option `--ftversion' has been added to freetype-config to
return the FreeType version.
- The memory debugger has been updated to dump allocation
statistics on all allocation sources in the library.
the X11 distribution using imake into mk/buildlink3/imake-check.mk.
imake-check.mk calls out to a helper shell script mk/buildlink3/imake-check
that generates the required Imakefiles and runs imake. Remove the
now extraneous builtin-imake.mk files as the builtin.mk files can now
contain the name of the imake symbol to check.
contain a command plus arguments. We use the standard idiom to extract
the first word of a list stored in a make variable:
VAR_CMD= ${VAR:C/^/_asdf_/1:M_asdf_*:S/^_asdf_//}
XXX This can be replaced with a more succinct use of variable modifiers
XXX when we update the bootstrap bmake to match the latest NetBSD make
XXX sources, i.e.:
XXX
XXX VAR_CMD= ${VAR:[1]}
Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.
