Hash : 3512a712

Date : 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.

Special notes to Unix users =========================== Please read the file `docs/UPGRADE.UNIX'. It contains important information regarding the installation of FreeType on Unix systems, especially GNU based operating systems like GNU/Linux. FreeType 2's library is called `libfreetype', FreeType 1's library is called `libttf'. They are *not* compatible! FreeType 2.4.3 ============== Please read the docs/CHANGES file, it contains IMPORTANT INFORMATION. Read the files `docs/INSTALL' for installation instructions. The FreeType 2 API reference is located in `docs/reference'; use the file `ft2-doc.html' as the top entry point. Additional documentation is available as a separate package from our sites. Go to http://download.savannah.gnu.org/releases/freetype/ and download one of the following files. freetype-doc-2.4.3.tar.bz2 freetype-doc-2.4.3.tar.gz ftdoc243.zip Bugs ==== Please report bugs by e-mail to `freetype-devel@nongnu.org'. Don't forget to send a detailed explanation of the problem -- there is nothing worse than receiving a terse message that only says `it doesn't work'. Alternatively, you may submit a bug report at https://savannah.nongnu.org/bugs/?group=freetype Enjoy!
