If in function `skip_spaces' the routine `skip_comment' comes to the
end of buffer, `cur' is still increased by one, so we need to check
for `p >= limit' and not `p == limit'.
* src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.
* src/truetype/ttinterp.c (Ins_MIRP): Typo, present since ages. The
code is now in sync with the other operators (e.g. MSIRP) which
modify twilight points.
* src/bdf/bdflib.c (_bdf_list_ensure): Bring code in sync with
comment before `_bdf_list_split', this is, really allocate at least
five `field' elements.
* src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if
_BDF_ENCODING isn't set. We need this because access to the `glyph'
variable might be undefined otherwise.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Use `FT_Pos'
instead of `FT_UInt' for some variables and update comparisons
accordingly. A detailed analysis can be found in the bug report.
* src/type1/t1load.c (parse_subrs): Add proper guards for `strncmp'.
* src/psaux/psobjs.c (ps_parser_skip_PS_token): Emit error message
only if cur < limit.
Jump instructions are now bound to the current function. The MS
Windows rasterizer behaves the same, as confirmed by Greg Hitchcock.
* src/truetype/ttinterp.h (TT_CallRec): Add `Cur_End' element.
* src/truetype/ttobjs.h (TT_DefRecord): Add `end' element.
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF): Check upper
bound of jump address.
(Ins_FDEF, Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns): Updated.
* include/freetype/internal/ftobjs.h (FT_ModuleRec, FT_LibraryRec):
Remove `generic' field since users can't access it.
* src/base/ftobjs.c (FT_Done_GlyphSlot): Call `generic.finalizer' as
advertised in the documentation of FT_Generic.
(Destroy_Module, FT_Done_Library): Updated to changes in `ftobjs.h'.
Patch submitted by anonymous reporter.
* src/gxvalid/gxvcommn.c (gxv_XStateTable_subtable_setup):
gxv_set_length_by_ulong_offset() must be called with 3, not 4,
the number of the subtables in the state tables; classTable,
stateArray, entryTable.
Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html
Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
are renamed with `ft_' suffixes.
* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
to `ft_raccess_rule_by_darwin_vfs()'.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Declarations of FT_RFork_Rule,
raccess_guess_rec, are moved to...
* include/freetype/internal/ftrfork.h: Here.
* include/freetype/internal/ftrfork.h:
FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
to replace raccess_guess_table[] in both of PIC and non-PIC
modes.
* src/base/ftrfork.c: raccess_guess_table[] array is rewritten
by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.
* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
the function pointer from `ft_raccess_guess_table' storage in
`BasePIC' structure.
* src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
FT_RACCESS_GUESS_TABLE_GET.
(raccess_get_rule_type_from_rule_index): Add `library' as the
first argument to the function, to retrieve the storage of
`ft_raccess_guess_table' from it. Also `raccess_guess_table'
is replaced by FT_RACCESS_GUESS_TABLE_GET.
(ft_raccess_rule_by_darwin_vfs): Ditto.
* src/autofit/afpic.c: Include "aflatin2.h" when
FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
Unconditionally inclusion causes declared but unimplemented
warning by GCC 4.6.
* src/cff/cffpic.c: The declarations of
FT_Init_Class_cff_cmap_encoding_class_rec() and
FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
They can be obtained by the inclusion of cffcmap.h.
cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
designed to declare xxx_pic_{free,init} by themselves.
Because these macros are used at the end of the module
interface (e.g. ttdriver.c) and the wrapper source to build
a module as a single object (e.g. truetype.c) includes
the PIC file (e.g. ttpic.c) before the module interface,
these macros are expanded AFTER xxx_pic_{free,init} body
when the modules are built as single object.
The declaration after the implementation causes the redundant
declaration warnings, so the declarations are moved to module
PIC headers (e.g. ttpic.h). Separating to other header files
are needed for multi build.
* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
Remove class_##_pic_free and class_##_pic_init declarations.
* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
FT_DEFINE_MODULE): Ditto.
* src/base/basepic.h: Insert a comment and fix coding style.
* src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
init}.
* src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
init}.
* src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
init}.
* src/raster/rastpic.h: Declare
ft_raster{1,5}_renderer_class_pic_{free,init}
* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
* src/smooth/ftspic.h: Declare
ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
* src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
set before derefering to obtain `library'. The initialization
of `clazz', `glyph', `library' and NULL pointer check are
reordered to minimize PIC conditonals.
* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
configuration, FT_DEFAULT_MODULES_GET returns
FT_Module_Class** pointer, GCC 4.6 warns that
const FT_Module_Class* const* variable is warned as
inappropriate to store it. To calm it, explicit cast is
inserted. Also `library' is checked to prevent the NULL
pointer dereference in FT_DEFAULT_MODULES_GET.
Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
take no arguments but derefer the variable named `library'
internally.
* src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
set it if non-NULL driver is passed.
* src/truetype/ttdriver.c (tt_get_interface): Ditto.
* src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library'
under PIC configuration, and set it if non-NULL module is given.
* src/psnames/psmodule.c (psnames_get_interface): Ditto.
error codes with per-module prefix.
* src/autofit/afpic.c: Include `aferrors.h'.
* src/cff/cffpic.c: Include `cfferrs.h'.
* src/pshinter/pshpic.c: Include `pshnterr.h'.
* src/raster/rastpic.c: Include `rasterrs.h'.
* src/sfnt/sfntpic.c: Include `sferrors.h'.
* src/smooth/ftspic.c: Include `ftsmerrs.h'.
* src/truetype/ttpic.c: Include `tterrors.h'.
