Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg c09a90a2 2016-01-12T22:28:14 Don't use macro names that start with `_[A-Z]' [3/3]. Such macro names are reserved for both C and C++. * src/cache/ftccache.h: s/_FTC_FACE_ID_HASH/FTC_FACE_ID_HASH/. Update all callers. (FTC_CACHE_LOOKUP_CMP): Replace `_XXX' with `XXX_'. * src/cache/ftcmru.c (FTC_MRULIST_LOOKUP_CMP): Ditto.
Werner Lemberg 2e9d2660 2016-01-12T21:40:53 Don't use macro names that contain `__' [2/2]. Such macro names are reserved for both C and C++. * src/cache/*: s/__/_/.
Werner Lemberg 37412ff9 2016-01-12T21:37:13 Don't use macro names that contain `__' [1/2]. Such macro names are reserved for both C and C++. */*: Replace macros of the form `__XXX_H__' with `XXX_H_'.
Werner Lemberg 3aaebe3a 2015-02-23T08:20:27 [cache] Replace `FT_PtrDist' with `FT_Offset'. * src/cache/ftccache.h (FTC_NodeRec): `FT_Offset' (a.k.a. `size_t') is a better choice for `hash' to hold a pointer than `FT_PtrDist' (a.k.a. `ptrdiff_t'), especially since the latter is signed, causing zillions of signedness warnings. [Note that `hash' was of type `FT_UInt32' before the change to `FT_PtrDist.] Update all users. * src/cache/ftcbasic.c, src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcglyph.c, src/cache/ftcglyph.h: Updated.
Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
Werner Lemberg f6aa089f 2013-05-10T07:58:47 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code.
Werner Lemberg 89f50647 2013-03-14T17:50:49 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.

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 875439cf 2010-10-25T15:43:01 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.
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.

David Turner dad2a2de 2006-03-20T11:48:13 * src/cache/ftccache.h, src/cache/ftcglyph.h, src/cache/ftcimage.h, src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h, src/cache/ftcmru.h: copying the cache's internal header files which were located in 'include/freetype/cache' to the 'src/cache' directory instead. Note that these files are not used by FreeType clients, all cache public APIs have been already moved to include/freetype/ftcache.h, and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it. the move is to allow us to modify the internals without intereference from rogue clients. Note that there are no known client that accesses the cache internals at the moment.
