Werner Lemberg f6aa089f12 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code. 2013-05-10 07:58:47 +02:00
Werner Lemberg 059bc335ce */*: Use `FT_THROW'.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

David Turner c0f9c4aadd introduce ft_mem_dup, ft_mem_strdup and ft_mem_strcpyn, and the corresponding
macros to use them (e.g. FT_STRDUP, FT_DUP and FT_STRCPYN)

modify the code to use them instead of raw mallocs/strcpy

David Turner ea4547ca03 * src/base/ftutil.c (ft_mem_qrealloc): fix the function
to accept 'item_size == 0' as well, though this sounds
  weird, it can theorically happen.

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.

David Turner c13e75fb1b * src/base/ftutil.c: ft_mem_alloc and related functions now return an
error if a negative size is passed in parameters.

    * src/cache/ftccache.c: make ftc_node_destroy FT_BASE_DEF, it needs to
    be exported for rogue clients

    * src/pshinter/pshglob.c: prevent problems with malformed fonts which
    have an odd number of blue values (these are broken according to the
    specs).

    * src/cff/cffload.c, src/type1/t1load.c: modify the loaders to force
    even-ness of 'num_blue_values'. Also change the CFF loader so that
    invalid entries in index files are ignored.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

David Turner e459d742e6 * include/freetype/internal/ftmemory.h, and a lot of other files !!:
changed the names of memory macros. Examples:

              MEM_Set   => FT_MEM_SET
              MEM_Copy  => FT_MEM_COPY
              MEM_Move  => FT_MEM_MOVE

              ALLOC     => FT_ALLOC
              FREE      => FT_FREE
              REALLOC   = >FT_REALLOC

            FT_NEW was introduced to allocate a new object from a _typed_
            pointer..

            note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
            by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
            arguments.

            This results in _lots_ of sources being changed, but makes the
            code more generic and less error-prone..

David Turner 53b3fa1da5 * renaming stream functions to the FT_Subject_Action scheme:
FT_Seek_Stream         => FT_Stream_Seek
          FT_Skip_Stream         => FT_Stream_Skip
          FT_Read_Stream         => FT_Stream_Read
          FT_Read_Stream_At      => FT_Stream_Read_At
          FT_Access_Frame        => FT_Stream_Enter_Frame
          FT_Forget_Frame        => FT_Stream_Exit_Frame
          FT_Extract_Frame       => FT_Stream_Extract_Frame
          FT_Release_Frame       => FT_Stream_Release_Frame
          FT_Get_XXXX            => FT_Stream_Get_XXXX
          FT_Read_XXXX           => FT_Stream_Read_XXXX

          note also that:

          FT_New_Stream( filename, stream ) =>
            FT_Stream_Open( stream, filename )

          (the function doesn't create the FT_Stream structure, it simply
           initializes it for reading)

          FT_New_Memory_Stream( library, FT_Byte*  base, size, stream ) =>
            FT_Stream_Open_Memory( stream, const FT_Byte* base, size )

          FT_Done_Stream => FT_Stream_Close

          note that the name of the stream methods, defined in
          "include/freetype/ftsystem.h" have also been changed without
          problems:

            FT_Stream_IO    => FT_Stream_IOFunc
            FT_Stream_Close => FT_Stream_CloseFunc
