a few fonts that require the automatic unpatented loader

Jens Claudius a787f45580 2006-08-27 Jens Claudius <jens.claudius@yahoo.com>
Fix miscellaneous compiler warnings.

	* freetype2/include/freetype/internal/ftobjs.h: close
	comment with `*/' to avoid `/* in comment' compiler warning.

	* freetype2/src/base/ftdbgmem.c (ft_mem_table_get_source): Turn
	cast `(FT_UInt32)(void*)' into `(FT_UInt32)(FT_PtrDist)(void*)'
	since on 64-bit platforms void* is larger than FT_UInt32.

	* freetype2/src/base/ftobjs.c (t_validator_error): cast
	away volatileness of argument to ft_longjmp. Spotted by
	Werner `Putzfrau' Lemberg.

	* freetype2/src/bdf/bdflib.c (bdf_load_font): initialize
	local variable `lineno'.

	* freetype2/src/gxvalid/gxvmod.c (classic_kern_validate):
	mark local variable `error' volatile.

Fix for previous commit, which caused many compiler warnings/errors
	about addresses of volatile objects passed as function arguments
	as non-volatile pointers.


	* freetype2/include/freetype/internal/ftvalid.h: Make
	FT_Validator typedef a pointer to a volatile object.

	* freetype2/src/gxvalid/gxvmod.c (gxv_load_table): Make function
	argument `table' a pointer to a volatile object.

	* freetype2/src/otvalid/otvmod.c (otv_load_table): Make function
	argument `table' a pointer to a volatile object.

* freetype2/src/gxvalid/gxvmod.c (GXV_TABLE_DECL): Mark local

	(classic_kern_validate): Same for local variables `memory',
	`ckern', and `valid'.

2006-06-26 19:12:51 +00:00
Werner Lemberg c011f4cba1 The Type 1 parser now skips over top-level procedures as required
for a `Simplified Parser'.  This makes the parser more robust as it
doesn't poke around in PostScript code.  Additionally, it makes the
FontDirectory hackery in src/type1/t1load.c unnecessary.

* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
(skip_literal_string): Add FT_Error as return value.
Handle escapes better.
(skip_string): Add FT_Error as return value.
Don't set `parser->error' but return error code directly.
(skip_procedure): New function.
(ps_parser_skip_PS_token): Handle procedures.
Update code.
(ps_parser_to_token): Update code.
(ps_parser_load_field_table): Handle bbox entries also.

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

David Turner 9482ba50b7 * include/freetype/ftstream.h, src/base/ftstream.c: modifying
various frame-related functions to report the place where the
    frames were entered/extracted/exited/released in the memory debugger.
2006-05-02 10:21:28 +00:00
David Turner 9ca782569c * include/freetype/internal/ftmemory.h, src/base/ftbitmap.c,
src/base/ftmac.c, src/base/ftrfork.c, src/lzw/ftzopen.c,
    src/raster/ftrend1.c, src/sfnt/ttpost.c, src/truetype/ttgxvar.c,
    src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
    against out-of-bounds conditions when allocating arrays. This is
    for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
    already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
    macros.

David Turner 264f307e66 * include/freetype/fterrdef.h, include/freetype/config/ftconfig.h,
include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
    src/base/ftutil.c: udpating the memory management functions and
    macros to safely deal with array size buffer overflows, this
    corresponds to attemps to allocate arrays that are too large. For
    an example, consider the following code:

         count = read_uint32_from_file();
         array = malloc( sizeof(Item) * count );
         for ( nn = 0; nn < count; nn++ )
           array[nn] = read_item_from_file();

    if 'count' is larger than FT_UINT_MAX/sizeof(Item), the multiplication
    will overflow and the array allocated will be smaller than the data
    read from the file. In this case, the heap will be trashed, and this
    can be used as a denial-of-service, or make the engine crash later.

    the FT_ARRAY_NEW and FT_ARRAY_RENEW macro now check that the new
    count is no more than FT_INT_MAX/item_size, otherwise, a new error,
    named 'FT_Err_Array_Too_Large' will be returned.

    note that the memory debugger now works again when FT_DEBUG_MEMORY
    is defined, and FT_STRICT_ALIASING has disappeared, the corresponding
    code being now the default.
