2004-06-23 Werner Lemberg <wl@gnu.org>
* 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 <david@freetype.org>
* 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.
