* include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare FT_QAlloc_Debug and FT_QRealloc_Debug. * src/base/ftutil.c (FT_QAlloc): Fix error and debug messages. (FT_QRealloc): Call FT_QAlloc if original pointer is NULL. Fix error message.

- * include/freetype/internal/ftmemory.h, src/base/ftutil.c,
- src/base/ftmemdbg.c: introducing the new FT_QAlloc and FT_QRealloc
- functions that do perform allocation without zero-ing out the
- corresponding blocks. Corresponding macros like FT_QALLOC, FT_QNEW,
- etc.. have been defined too
+ * include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare
+ FT_QAlloc_Debug and FT_QRealloc_Debug.
- * include/freetype/config/ftmodule.h: changed the order of modules
- in order to _dramatically_ improve the performance of face open/close
- operations. For example, putting the TrueType driver first in the
- list results in a 5X speedup when opening Vera.ttf !!
+ * src/base/ftutil.c (FT_QAlloc): Fix error and debug messages.
+ (FT_QRealloc): Call FT_QAlloc if original pointer is NULL.
+ Fix error message.
- The problem is really that the PCF and/or BDF drivers are broken
- and do a lot more than necessary simply to detect that they
- cannot handle the font file.
+2004-06-23 David Turner <[email protected]>
- * src/sfnt/ttload.c: small optimization in the kerning table
- verifier, speeds up TrueType face opening by about 7%.
+ * include/freetype/internal/ftmemory.h, src/base/ftutil.c
+ (FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,
+ FT_QRealloc_Debug): New functions that perform allocation without
+ zero-ing out the corresponding blocks.
- Also changed code to use the new FT_QNEW_ARRAY call when
- appropriate to slightly improve performance.
+ * include/freetype/internal/ftmemory.h (FT_MEM_QALLOC,
+ FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY,
+ FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY,
+ FT_QRENEW_ARRAY): New macros.
+
+ * src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC.
+ * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use FT_QNEW_ARRAY.
+ * src/sfnt/sfobjs.c (tt_face_get_name): Use FT_QNEW_ARRAY.
+
+ * src/sfnt/ttload.c (tt_face_load_directory, tt_face_load_metrics,
+ tt_face_load_gasp): Use FT_QNEW_ARRAY.
+ (tt_face_load_kern): Use FT_QNEW_ARRAY.
+ Small optimization in the kerning table verifier; this speeds up
+ TrueType face opening by about 7%.
+ (tt_face_load_hdmx): Use FT_QNEW_ARRAY and FT_QALLOC.
+
+ * include/freetype/config/ftmodule.h: Changed the order of modules,
+ putting TrueType and Type 1 first. This dramatically improves the
+ performance of face open/close operations. For example, putting the
+ TrueType driver first in the list results in a 5x speedup when
+ opening `Vera.ttf'.
+
+ The very problem is that both the PCF and BDF drivers do a lot more
+ than necessary to detect that they cannot handle a font file.
