- 2012-03-03 Werner Lemberg <wl@gnu.org>
- Fix Savannah bug #35660.

- [psaux] Fix Savannah bug #35657.
- If in function `skip_spaces' the routine `skip_comment' comes to the
- end of buffer, `cur' is still increased by one, so we need to check
- for `p >= limit' and not `p == limit'.
- * src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
- PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.
- 2012-03-01 Werner Lemberg <wl@gnu.org>

- modify twilight points.
- 2012-03-01 Werner Lemberg <wl@gnu.org>
- [bdf] Fix Savannah bug #35643.
- * src/bdf/bdflib.c (_bdf_list_ensure): Bring code in sync with
- comment before `_bdf_list_split', this is, really allocate at least
- five `field' elements.
- 2012-03-01 Werner Lemberg <wl@gnu.org>
- [bdf] Fix Savannah bug #35641.
- * src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if

- [autofit] Fix the inclusion of `aflatin2.h' in PIC file.
- * src/autofit/afpic.c: Include `aflatin2.h' when
- FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
- Unconditionally inclusion causes declared but unimplemented
- warning by GCC 4.6.
- 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
- * src/cff/cffpic.c: The declarations of
- FT_Init_Class_cff_cmap_encoding_class_rec() and
- FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
- They can be obtained by the inclusion of cffcmap.h.
- cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
- FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
- 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Fix redundant declaration warning in PIC mode.
- Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
- designed to declare xxx_pic_{free,init} by themselves.
- Because these macros are used at the end of the module
- interface (e.g. ttdriver.c) and the wrapper source to build
- a module as a single object (e.g. truetype.c) includes
- the PIC file (e.g. ttpic.c) before the module interface,
- these macros are expanded AFTER xxx_pic_{free,init} body
- when the modules are built as single object.
- The declaration after the implementation causes the redundant
- declaration warnings, so the declarations are moved to module
- PIC headers (e.g. ttpic.h). Separating to other header files
- are needed for multi build.
- * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
- Remove class_##_pic_free and class_##_pic_init declarations.
- * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
- FT_DEFINE_MODULE): Ditto.
- * src/base/basepic.h: Insert a comment and fix coding style.
- * src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
- init}.
- * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
- * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
- init}.
- * src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
- init}.
- * src/raster/rastpic.h: Declare
- ft_raster{1,5}_renderer_class_pic_{free,init}
- * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
- * src/smooth/ftspic.h: Declare
- ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
- * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
- 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Make pspic.c to include module error header to fix multi build.
- * src/psnames/pspic.c: Include `psnamerr.h'.
- 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [base] Fix a dereference of uninitialized variable in PIC mode.
- * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
- set before derefering to obtain `library'. The initialization
- of `clazz', `glyph', `library' and NULL pointer check are
- reordered to minimize PIC conditonals.
- 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [base] Insert explicit cast for GCC 4.6 in PIC mode.
- * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
- configuration, FT_DEFAULT_MODULES_GET returns
- FT_Module_Class** pointer, GCC 4.6 warns that
- const FT_Module_Class* const* variable is warned as
- inappropriate to store it. To calm it, explicit cast is
- inserted. Also `library' is checked to prevent the NULL
- pointer dereference in FT_DEFAULT_MODULES_GET.
- 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
- Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
- take no arguments but derefer the variable named `library'
- internally.
- * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
- set it if non-NULL driver is passed.
- * src/truetype/ttdriver.c (tt_get_interface): Ditto.
- * src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library'
- under PIC configuration, and set it if non-NULL module is given.
- * src/psnames/psmodule.c (psnames_get_interface): Ditto.
- 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

- properly.
- 2012-01-02 Werner Lemberg <wl@gnu.org>
- Fix tracing message for `loca' table.
- * src/truetype/ttpload.c (tt_face_get_location): Don't emit a
- warning message if the last `loca' entry references an empty glyph.
- 2011-12-10 Werner Lemberg <wl@gnu.org>
- Add some variable initializations.
- Reported by Richard COOK <rscook@unicode.org>.

- * src/smooth/ftgrays.c (gray_render_conic): Initialize `levels'
- earlier.
- 2011-12-08 Werner Lemberg <wl@gnu.org>

- * src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by
- `FT_Load_Glyph' must be simply multiplied by 1024.
- 2011-12-08 Werner Lemberg <wl@gnu.org>
- * src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing.
- 2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
- Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
- was a configurable macro to disable Carbon-dependent code. Because
- now configure script sets DARWIN_NO_CARBON by default and disables
- Darwin & Carbon-dependent codes, these macros can be unified.
- FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
- (defined by default) is removed, because DARWIN_NO_CARBON violates
- FT_XXX naming convention of public macros, and a macro configured by

- make devel).
- * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
- old Mac font support is requested and Carbon is available.
- * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support

- * src/tools/apinames.c (names_add): Change the type of `h' from
- int to unsigned int, to prevent undefined behaviour in the

- 2011-11-27 Werner Lemberg <wl@gnu.org>
- [bdf] Fix Savannah bug #34896.
- ENCODING now covers the whole Unicode range.
- Note, however, that this change is quite expensive since it
- increases the size of three arrays by almost 400kByte in total. The
- right fix is to replace the logic with something smarter.
- Additionally, there exist very old BDFs for three-byte CCCII
- encoding which exceeds the range of Unicode (another reason to have
- a smarter logic).

- [smooth] Slightly optimize conic and cubic flatterners.
- * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move
- out some code from the main loop to speed it up.
- 2011-09-11 Tomas Hoger <thoger@redhat.com>
- Slightly improve LZW_CLEAR handling.
- * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
- Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
- handled as clear codes. This also re-sets old_code and old_char to
- predictable values, which is a little better than using `random'
- ones if the code following LZW_CLEAR is invalid.
- 2011-09-11 Tomas Hoger <thoger@redhat.com>
- Add explicit LZW decompression stack size limit.
- Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
- constructed correctly. It's even less than that, see e.g.
- libarchive code comment for a better size upper bound:
- http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
- This patch adds explicit stack size limit, enforced when stack is
- realloced.
- An alternative is to ensure that code < state->prefix[code - 256]
- when traversing prefix table. Such check is less efficient and
- should not be required if prefix table is constructed correctly in
- the first place.
- * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
- 2011-09-11 Tomas Hoger <thoger@redhat.com>
- Protect against loops in the prefix table.
- LZW decompressor did not sufficiently check codes read from the
- input LZW stream. A specially-crafted or corrupted input could
- create a loop in the prefix table, which leads to memory usage
- spikes, as there's no decompression stack size limit.
- * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
- code in valid LZW stream must be 0..255.
- <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
- code > free_ent is invalid.
- 2011-09-09 Werner Lemberg <wl@gnu.org>

- o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
- joins (not bevel joins) were generated. Indeed, the meanings of
- `miter' and `bevel' were incorrectly reversed (consistently) in
- both the code and comments.
- o The way bevel joins were constructed (whether specified
- explicitly, or created as a result of exceeding the miter limit)
- did not match what is required for stroked text in PostScript or
- PDF.
- The main fixes
- --------------
- o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
- o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
- introduced to support PostScript and PDF miter joins.
- o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
- alias for FT_STROKER_LINEJOIN_MITER.
- Additionally, a variety of stroking errors have been fixed. These
- would cause various artifacts (including points `at infinity'),
- especially when stroking poor quality fonts.
- See
- http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
- for example documents. The FreeType stroker now produces results
- very similar to that produced by GhostScript and Distiller for these
- fonts.
- Other problems
- --------------
- The following problems have been resolved:
- o Inside corners could be generated incorrectly. Intersecting the
- inside corner could cause a missing triangular area and other
- effects.
- The intersection point can only be used if the join is between
- two lines and both lines are long enough. The `optimization'
- condition in `ft_stroker_inside' has been corrected; this
- requires the line length to be passed into various functions and
- stored in `FT_StrokerRec'.
- o Incorrect cubic curves could be generated. The angle
- calculations in `FT_Stroker_CubicTo' have been corrected to
- handle the case of the curve crossing the +/-PI direction.
- o If the border radius was greater than the radius of curvature of
- a curve, then the negative sector would end up outside (not
- inside) the border. This situation is now recognized and the
- negative sector is circumnavigated in the opposite direction.
- (If round line joins are being used, this code is disabled
- because the line join will always cover the negative sector.)
- o When a curve is split, the arcs may not join smoothly (especially
- if the curve turns sharply back on itself). Changes in
- direction between adjacent arcs were not handled. A round
- corner is now added if the deviation from one arc to the next is
- greater than a suitable threshold.
- o The current direction wasn't retained if a the outline contained
- a zero length lineto or a curve that was determined to be
- `basically a point'. This could cause a spurious join to be
- added.
- o Cubics with close control points could be mishandled. All eight
- cases are now distinguished correctly.
- Other improvements
- ------------------
- o Borders for cubic curves could be too `flat'.
- FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
- this.
- o The handling and use of movable points has been simplified a
- little.
- o Various values are now computed only if the results are actually
- needed.
- o The directions of the outer and inner borders have been swapped,
- as recommended by Graham Asher.

- [autofit] Blur CJK stems if too many to preserve their gaps.
- When there are too many stems to preserve their gaps in the
- rasterization of CJK Ideographs at a low resolution, blur the
- stems instead of showing clumped stems. See

- * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
- the previous stem by `has_last_stem' and `last_stem_pos', and skip

- Previously, signed integers were converted to unsigned integers, but
- this can fail because of sign extension. For example, 0xa344a1eb

- Fix ARM assembly code in include/freetype/config/ftconfig.h.
- * include/freetype/config/ftconfig.h (FT_MulFix_arm):
- Copy the maintained code from builds/unix/ftconfig.in.
- Old GNU binutils could not accept the reduced syntax
- `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
- `orr %0, %0, %2, lsl #16' is better. Reported by

- 2011-01-15 Werner Lemberg <wl@gnu.org>
- [raster] Make bbox handling the same as with Microsoft's rasterizer.

- 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.

- 2011-01-13 Werner Lemberg <wl@gnu.org>
- [raster] Add undocumented drop-out rule to the other bbox side also.
- * src/raster/ftraster.c (Vertical_Sweep_Drop,

- 2011-01-13 Werner Lemberg <wl@gnu.org>
- [raster] Reduce jitter value.
- This catches a rendering problem with glyph `x' from Tahoma at
- 10ppem. It seems that the increase of the precision in the change
- from 2009-06-11 makes a larger jitter value unnecessary.
- * src/raster/ftraster.c (Set_High_Precision): Implement it.
- 2011-01-13 Werner Lemberg <wl@gnu.org>
- [raster] Handle drop-outs at glyph borders according to Microsoft.
- If a drop-out rule would switch on a pixel outside of the glyph's
- bounding box, use the right (or top) pixel instead. This is an
- undocumented feature, but some fonts like `Helvetica Neue LT Com 65
- Medium' heavily rely on it.
- Thanks to Greg Hitchcock who explained this behaviour.
- * src/raster/ftraster.c (Vertical_Sweep_Drop,
- Horizontal_Sweep_Drop): Implement it.

- [cache] Fix Savannah bug #31923, patch drafted by Harsha.
- When a node comparator changes the cached nodes during the
- search of a node matching with queried properties, the
- pointers obtained before the function should be updated to
- prevent the dereference to freed or reallocated nodes.
- To minimize the rescan of the linked list, the update is
- executed when the comparator notifies the change of cached
- nodes. This change depends previous change:
- 38b272ffbbdaae276d636aec4ef84af407d16181
- * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
- top node if the cached nodes are changed.
- * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
- 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] Notice if a cache query induced the node list change.
- Some node comparators (comparing the cache node contents and the
- properties specified by the query) can flush the cache node to
- prevent the cache inflation. The change may invalidate the pointers
- to the node obtained before the node comparison, so it should be
- noticed to the caller. The problem caused by the cache node
- changing is reported by Harsha, see Savannah bug #31923.
- * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
- `FT_Bool* list_changed' to indicate the change of the cached nodes
- to the caller.
- (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
- `_list_changed'.
- (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
- and update it when `FTC_Manager_FlushN' flushes any nodes.
- * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
- FTC_Node_CompareFunc type.
- (ftc_gnode_compare): Ditto.
- * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
- list_changed' to indicate the change of the cache nodes (anyway, it
- is always FALSE).
- * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (ftc_cmap_node_remove_faceid): Ditto.
- * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
- `FTC_CACHE_TRYLOOP_END', because the result is not needed.
- (FTC_Cache_Lookup): Watch the change of the cache nodes by
- `list_changed'.
- (FTC_Cache_RemoveFaceID): Ditto.
- * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_gnode_compare): New argument `FT_Bool* list_changed' to
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
- passed to `ftc_gnode_compare'.
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
- * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
- list_changed' to indicate the change of the cache nodes, anyway. It
- is updated by `FTC_CACHE_TRYLOOP'.
- (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
- passed to `ftc_snode_compare'.
- * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
- 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
- argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
- prototype.
- * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
- `cache' is not used by its child `ftc_gnode_compare'.
- 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] Deduplicate the code to get the top node by a hash.
- There are several duplicated code fragments getting the top node
- from a cache by a given hash, like:
- idx = hash & cache->mask;
- if ( idx < cache->p )
- idx = hash & ( cache->mask * 2 + 1 );
- pnode = cache->buckets + idx;
- To remove duplication, a cpp-macro to do same work
- `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
- configuration, non-`ftc_get_top_node_for_hash' is also introduced.
- * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
- and implement inlined version.
- (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
- * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
- version.
- (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
- (ftc_node_hash_link): Ditto.
- (FTC_Cache_Lookup): Ditto.
- 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] inline-specific functions are conditionalized.
- * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
- inlined configuration. This function is a thin wrapper of
- `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
- `nodecmp' argument). Under non-inlined configuration,
- `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
- `FTC_Cache->clazz.node_compare'.
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
- * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
- `ftc_snode_compare'.
- * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
- 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] Correct a type mismatch under non-inlined config.
- * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
- takes the node via a pointer `FTC_Node*', differently from cpp-macro
- `FTC_CACHE_LOOKUP_CMP'.
- 2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Update Jamfile to include Bzip2 support.

- 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Update Symbian project files to include Bzip2 support.

- * builds/unix/freetype2.in: Ditto.
- 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
- SYSTEM_ZLIB is used to switch the builtin zlib source
- or system zlib source out of FreeType2. But ftbzip2
- module has no builtin bzip2 library and always requires
- system bzip2 library. Thus SYSTEM_BZ2LIB is always yes,

- 2010-12-25 Harsha <mm.harsha@gmail.com>
- Apply Savannah patch #7422.
- If we encounter a space in a string then the sbit buffer is NULL,
- height and width are 0s. So the check in ftc_snode_compare will
- always pass for spaces (comparision with 255). Here the comments
- above the condition are proper but the implementation is not. When
- we create an snode I think it is the proper way to initialize the
- width to 255 and then put a check for being equal to 255 in snode
- compare function.

- 2010-11-01 Alexei Podtelezhnikov <apodtele@gmail.com>
- [ftsmooth] Improve rendering.
- * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
- cubic deviations have been estimated _after_ UPSCALE, whereas
- conic ones have been evaluated _before_ UPSCALE, which produces

- 2010-10-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'.
- * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert
- the type of `_idx' from FT_PtrDist (by previous change)
- to original FT_UFast, to match with FT_CacheRec.
- 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] Change the hash types to FT_PtrDist.
- On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
- variables are inappropriate to calculate hash values
- from the memory address (64-bit). The hash variables
- are extended from FT_ULong to FT_PtrDist and new
- hashing macro functions are introduced. The hash
- values on 16-bit memory platforms are changed, but
- ILP32 and LP64 are not changed. The hash value in
- the cache subsystem is not reverted to the memory
- address, so using signed type FT_PtrDist is safe.
- * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
- function to replace `FTC_FACE_ID_HASH' for portability.
- * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
- `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.
- * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
- * src/cache/ftccache.h (FTC_NodeRec): The type of the
- member `hash' is changed from FT_UInt32 to FT_PtrDist.
- * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
- argument `hash' is changed from FT_UInt32 to FT_PtrDist.
- (FTC_Cache_NewNode): Ditto.
- * src/cache/ftccache.c (ftc_cache_add): Ditto.
- (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
- * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
- * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
- * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
- of the internal variable `hash' is changed to FT_PtrDist
- from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
- (FTC_SBitCache_Lookup): Ditto.
- (FTC_SBitCache_LookupScaler): Ditto.
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
- * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
- Also the type of the internal variable `_idx' is changed to
- FT_PtrDist from FT_UFast for better pointer calculation.
- 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cache] Hide internal macros incompatible with LLP64.
- `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and
- `FTC_IMAGE_TYPE_HASH' are enclosed by
- FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
- normal clients.
- For the history of these macros, see the investigation:
- http://lists.gnu.org/archive/html/freetype/2010-10/msg00022.html
- 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.
- On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
- cannot cover the memory address (64-bit). `FT_MEM_VAL' is
- used for hashing only and not dereferred, so using signed
- type FT_PtrDist is safe.
- * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
- return value from FT_ULong to FT_PtrDist.
- (ft_mem_table_resize): The type of hash is changed to
- FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
- 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Replace "%lx" for memory address by "%p", LLP64 platforms.
- On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
- the memory address (64-bit). Also the casts from the pointer
- type to long int should be removed to preserve the address
- correctly.
- * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
- (End_Profile) Ditto.
- * src/truetype/ttinterp.c (Init_Context): Ditto.
- 2010-10-15 Alexei Podtelezhnikov <apodtele@gmail.com>
- Fix thinko in spline flattening.
- FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL.
- * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and
- replace it everywhere with ONE_PIXEL/8.
- 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [raccess] Skip unrequired resource access rules by Darwin VFS.
- When a resource fork access rule by Darwin VFS could open the
- resource fork but no font is found in it, the rest of rules
- by Darwin VFS are skipped. It reduces the warnings of the
- deprecated resource fork access method by recent Darwin kernel.
- Fix MacPorts ticket #18859:
- http://trac.macports.org/ticket/18859
- * src/base/ftobjs.c (load_face_in_embedded_rfork):
- When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
- means that the file is possible to be `fopen'-ed but zero-sized.
- Also there is a case that the resource fork is not zero-sized,
- but no supported font exists in it. If a rule by Darwin VFS
- falls into such cases, there is no need to try other Darwin VFS
- rules anymore. Such cases are marked by vfs_rfork_has_no_font.
- If it is TRUE, the Darwin VFS rules are skipped.
- 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [raccess] Grouping resource access rules based on Darwin VFS.
- MacOS X/Darwin kernel supports a few tricky methods to access
- a resource fork via ANSI C or POSIX interface. Current resource
- fork accessor tries all possible methods to support all kernels.
- But if a method could open a resource fork but no font is found,
- there is no need to try other methods older than tested method.
- To determine whether the rule index is for Darwin VFS, a local
- function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
- To use this function in ftobjs.c etc but it should be inlined,
- it is exposed by ftbase.h.
- * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
- the rules to access the resource fork.
- (raccess_guess_rec): New structure to bind the rule function and
- rule enum type.
- (FT_Raccess_Guess): The list of the rule functions is replaced by
- (raccess_guess_table): This. This is exposed to be used by other
- intra module functions.
- (raccess_rule_by_darwin_vfs): A function to return a boolean
- if the rule specified by the rule index is based on Darwin VFS.
- 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- Prevent to open a FT_Stream for zero-sized file on non-Unix.
- builds/unix/ftsystem.c prevents to open an useless stream from
- zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
- stream drivers for ANSI C, Amiga and VMS return useless streams.
- For cross-platform consistency, all stream drivers should act
- same.
- * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
- file is zero, FT_Err_Cannot_Open_Stream is returned.
- * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
- * src/vms/ftsystem.c (FT_Stream_Open): Ditto.

- 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cff] Truncate the element length at the end of the stream.
- See Savannah bug #30975.
- * src/cff/cffload.c (cff_index_access_element): `off2', the offset
- to the next element is truncated at the end of the stream to prevent
- invalid I/O. As `off1', the offset to the requested element has
- been checked by `FT_STREAM_SEEK', `off2' should be checked
- similarly.
- 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
- [cff] Ignore CID > 0xFFFFU.
- See Savannah bug #30975.

- See Savannah bug #31040 for detail.
- * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
- FT_GlyphZoneRec size->twilight to be freed. If duplicated,
- `FT_FREE' erases the duplicated pointers only and leave original
- pointers. They can cause the double-free crash when the burst
- errors occur in TrueType interpreter and `free_buffer_in_size' is
- invoked repeatedly.
- 2010-09-15 Werner Lemberg <wl@gnu.org>
- Make bytecode debugging with FontForge work again.

- [truetype] Prevent bytecode reuse after the interpretation error.
- * src/truetype/ttinterp.c (free_buffer_in_size): New function to
- free the buffer allocated during the interpretation of this glyph.
- (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
- an error occurs in the bytecode interpretation. The interpretation
- of invalid bytecode may break the function definitions and referring
- them in later interpretation is danger. By unsetting these flags,
- `fpgm' and `prep' tables are executed again in next interpretation.

- [cff] Allow SIDs >= 65000.
- * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:

- Force hinting when the font lacks its familyname.
- In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
- stream may lack `name' table because they are not required. Hinting
- for nameless fonts is safer for PDFs including embedded Chinese
- fonts. Written by David Bevan, see:

- 2010-05-10 Ken Sharp <ken.sharp@artifex.com>
- Fix Savannah bug #29846.
- Previously we discovered fonts which used `setcurrentpoint' to set
- the initial point of a contour to 0,0. This caused FreeType to
- raise an error, because the `setcurrentpoint' operator is only
- supposed to be used with the results from an OtherSubr subroutine.
- This was fixed by simply ignoring the error and carrying on.
- Now we have found a font which uses setcurrentpoint to actually
- establish a non-zero point for a contour during the course of a
- glyph program. FWIW, these files may be produced by an application
- called `Intaglio' on the Mac, when converting TrueType fonts to
- Type 1.
- The fix allows the new invalid behaviour, the old invalid behaviour
- and real proper usage of the operator to work the same way as Adobe
- interpreters apparently do.
- (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
- two elements of the stack to establish unconditionally the current x
- and y coordinates.
- Make the `flex' subroutine handling (OtherSubr 0) put the current
- x,y coordinates onto the stack, instead of two dummy uninitialised
- values.
