suzuki toshiya 0ae3271814 Restrict the number of the charmaps in a rogue-compatible mode.
Fix for Savannah bug #30059.

* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the
minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This.  It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).

* src/cff/cffobjs.c (cff_face_init): Abort the automatic
selection or synthesis of Unicode cmap subtable when the charmap
index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message

is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search
earlier one.
(find_variant_selector_charmap): When UVS charmap is found after
FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
(FT_Select_Charmap): When a charmap matching with requested
encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Set_Charmap): When a charmap matching with requested
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Get_Charmap_Index): When a requested charmap is found
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
index.

2010-07-03 15:31:38 +02:00
suzuki toshiya b2ea64bcc6 Additional fix for Savannah bug #30306.
* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type
of the POST fragment is 0, the segment is completely ignored.
The declared length of the segment is not cared at all.
According to Adobe Technical Note 5040, type 0 segment is
comment only and should not be loaded for the interpreter.
Reported by Robert Swiecki.
