Werner Lemberg f6aa089f 2013-05-10T07:58:47 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
suzuki toshiya ae6d1d7b 2011-02-20T19:13:25 [cache] Fix an off-by-one bug in FTC_Manager_RemoveFaceID(). Found by <ychen1392001@yahoo.com.cn>, see detail in http://lists.gnu.org/archive/html/freetype/2011-01/msg00023.html * src/cache/ftccache.c (FTC_Cache_RemoveFaceID): Check the node buckets[cache->p + cache->mask] too.
Werner Lemberg 3757b1e1 2011-01-13T10:33:04 Cleanup/formatting.
suzuki toshiya 5e7ad208 2011-01-09T23:09:36 [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 functon 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.
suzuki toshiya 38b272ff 2011-01-09T22:49:07 [cache] Notice if a cache query induced the node list change. Some node comparators (comparing the cache node content 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 the change 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.
suzuki toshiya 9a2e255b 2011-01-09T21:09:58 [cache] Deduplicate the code to get the top node by a hash. There are several duplicated codes 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 deduplicate them, a cpp-macro to do same work FTC_NODE__TOP_FOR_HASH( cache, hash ) is introduced. For non-inlined config, 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.
suzuki toshiya 3512a712 2010-10-25T02:07:52 [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_UInt32 for better pointer calculation.
Teijo Kinnunen ebaeb642 2010-08-17T07:40:55 Fix Savannah bug #30788. * src/cache/ftccache.c (FTC_Cache_Clear): Check `cache->buckets' for NULL too.
Werner Lemberg f765e440 2010-06-24T10:34:29 */*: Use module specific error names where appropriate.
Werner Lemberg ca87cd0b 2009-10-06T11:09:29 Fix `make multi'. * src/cache/ftccache.c, src/cache/ftcsbits.c (FT_COMPONENT): Define. * src/sfnt/sfdriver.c: Include FT_INTERNAL_DEBUG_H.
suzuki toshiya b566d42a 2009-08-01T00:30:19 cache: Fix some data types mismatching with their sources.
Werner Lemberg 858abbed 2009-06-26T06:15:41 For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings.

Werner Lemberg 98d6a3ac 2006-02-27T19:49:34 * src/cache/ftccache.c (ftc_node_destroy) [!FT_CONFIG_OPTION_OLD_INTERNALS]: Mark as FT_LOCAL_DEF. This should now fix all possible compilation options.
David Turner c13e75fb 2006-02-27T13:14:42 * src/base/ftutil.c: ft_mem_alloc and related functions now return an error if a negative size is passed in parameters. * src/cache/ftccache.c: make ftc_node_destroy FT_BASE_DEF, it needs to be exported for rogue clients * src/pshinter/pshglob.c: prevent problems with malformed fonts which have an odd number of blue values (these are broken according to the specs). * src/cff/cffload.c, src/type1/t1load.c: modify the loaders to force even-ness of 'num_blue_values'. Also change the CFF loader so that invalid entries in index files are ignored.
Werner Lemberg ae1e4b15 2006-02-25T17:11:04 * src/cache/ftccache.c (ftc_node_destroy): Use FT_LOCAL_DEF (again).

David Turner 6a681fa8 2006-01-27T12:11:22 * src/autofit/afwarp.c: simple #ifdef to prevent compilation when the warp hinter isn't active (it shouldn't, still experimental) * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid" and "otvalid" from the list of modules that are linked statically to a given FreeType library. Functionality has been moved to the "ftvalid" CVS module. note also that current Make-based build system still compiles the modules though... * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING, which controls the definitions of the memory management functions to avoid warnings with recent versions of GCC. this macro is only here to be disabled, in case we detect problems with the new scheme. NOTE: disable macro to use the memory debugger. this will be fixed later !!
Werner Lemberg d829ff76 2005-11-12T17:07:11 * src/cache/ftccache.c (FTC_Cache_Clear), src/cache/ftcmanag.c (FTC_Manager_Check): Remove FT_EXPORT_DEF tag. * src/base/ftcalc.c (FT_Add64): Remove FT_EXPORT_DEF tag.

Werner Lemberg 92aa527a 2005-05-23T21:33:02 * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk (CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove -fno-strict-aliasing. Say you have `(Foo*)x' and want to assign, pass, or return it as `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler would warn you that type casting incompatible pointer types breaks strict-aliasing. The solution is to cast to `(void*)' instead which is the generic pointer type, so the compiler knows that it should make no strict-aliasing assumption on `x'. But the problem with `(void*)x' is that seems like in C++, unlike C, `void*' is not a generic pointer type and assigning `void*' to `Bar*' without a cast causes an error. The solution is to cast to `Bar*' too, with `(Bar*)(void*)x' as the result -- this is what the patch does. * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove cast on lvalue, use a temporary pointer instead. Cast temporarily to (void*) to not break strict aliasing. * include/freetype/internal/ftmemory.h (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE), src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*) to not break strict aliasing. * src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information. * builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c -- it is currently loaded from ttsbit.c.

Further optimizations to come shortly anyway... - the FTC_CMapCache_Lookup function has changed its signature, charmaps can now only be retrieved by index - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in private header for the moment)

(FNT_Size_Set_Pixels): To find a strike, first check pixel_height only, then try to find a better hit by comparing pixel_width also. Without this fix it isn't possible to access all strikes. Also compute metrics.max_advance to be in sync with other bitmap drivers. * src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code. (FT_Set_Pixel_Size): Assign value to `metrics' after validation of arguments. Synchronize computation of height and width for bitmap strikes. The `width' field in the FT_Bitmap_Size structure is now only useful to enumerate different strikes.

See the description of "FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX" in DEBUG.TXT * src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c, ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory conditions. * src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a small memory leak * src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that only happened when trying to resize an array would end in an OOM. * src/smooth/ftgrays.c: removed compiler warnings / volatile bug * src/truetype/ttobjs.c: removed segmentation fault that happened in tight memory environments.
David Turner 20e33158 2003-01-07T22:54:02 * src/base/ftstroker.c: probably the last bug-fixes to the stroker, the API is likely to change however. * src/base/fttrigon.c (FT_Angle_Diff): fixing function, it returned invalid values for large negative angle differences (resulting in incorrect stroker computations, among other things) * src/cache/ftccache.c (ftc_node_unlink): removing incorrect assertion, and changing code to avoid hash table size contraction * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: adding "ftstroker.obj" to default build, as optional component
Werner Lemberg 3c403e4c 2002-08-06T21:47:40 Some formatting. * src/cff/cffcmap.c: Remove compiler warnings. * src/cache/ftccache.c, src/cache/ftccache.i, src/pfr/pfrload.c, src/pfr/pfrgload.c: s/index/idx/. * src/cff/cffload.c: s/select/fdselect/. * src/raster/ftraster.c: s/wait/waiting/.

David Turner 957fa856 2002-06-08T13:48:41 - removing a typo in ftccache.i that prevented it from compiling correctly - fixed the infamous bug that caused the cache to crash with large fonts. the hash table buckets array wasn't shrinked correctly during cache flushes..
Werner Lemberg 8c90c22d 2002-06-08T06:47:18 * src/cache/ftccache.c (ftc_node_hash_unlink, ftc_node_hash_link) [FTC_CACHE_USE_LINEAR_HASHING]: Fix returned error code. Fix debugging messages. * src/type42/t42error.h: New file. * src/type42/t42drivr.c, src/type42/t42objs.c, src/type42/t42parse.c: Use t42 error codes. * src/type42/rules.mk: Updated. * src/base/ftnames.c: Include FT_INTERNAL_STREAM_H. Formatting, adding copyright messages.

David Turner e459d742 2002-03-22T13:52:37 * include/freetype/internal/ftmemory.h, and a lot of other files !!: changed the names of memory macros. Examples: MEM_Set => FT_MEM_SET MEM_Copy => FT_MEM_COPY MEM_Move => FT_MEM_MOVE ALLOC => FT_ALLOC FREE => FT_FREE REALLOC = >FT_REALLOC FT_NEW was introduced to allocate a new object from a _typed_ pointer.. note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer arguments. This results in _lots_ of sources being changed, but makes the code more generic and less error-prone..
