f1a981b5	2011-01-31T22:26:53	[truetype] Protect jump instructions against endless loops. * src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error if offset is zero.
d6a213f8	2011-01-31T18:51:07	[truetype] Improve handling of invalid references. * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference error codes only if pedantic hinting is active. At the same time, try to provide sane values which hopefully allow useful continuation. Exception to this is CALL and LOOPCALL – due to possible stack corruption it is necessary to bail out.
96f04564	2011-01-31T10:24:32	[truetype] Improve handling of stack underflow. * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, Ins_DELTAC): Exit with error only if `pedantic_hinting' is set. Otherwise, try to do something sane.
0682251e	2011-01-30T16:38:09	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message.
c61b3596	2011-01-30T16:29:45	[truetype]: Fix behaviour of MIAP for invalid arguments. * src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in case of error.
dcdb3167	2011-01-18T07:35:26	[truetype] Fix handling of MIRP instruction. Thanks to Greg Hitchcock who explained the issue. * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with `>' since the description in the specification is incorrect. This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 65 medium' at 15ppem.
9073e7ce	2010-11-26T11:58:08	[truetype] Better multi-threading support. * src/truetype/ttinterp.c (TT_Load_Context): Reset glyph zone references.
46c371c2	2010-10-25T00:14:13	Replace "%lx" for memory address by "%p", LLP64 platforms. On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover the memory address (64-bit). Also the casts from the pointer type to long int should be removed to preserve the address correctly. * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". (End_Profile) Ditto. * src/truetype/ttinterp.c (Init_Context): Ditto.
0edf0986	2010-10-06T11:52:27	[truetype] Improve error handling of `SHZ' bytecode instruction. Problem reported by Chris Evans <scarybeasts@gmail.com>. * src/truetype/ttinterp.c (Ins_SHZ): Check `last_point'.
5edc2f33	2010-10-01T08:15:55	Fix Savannah bug #31040. * src/truetype/ttinterp.c (free_buffer_in_size): Remove. (TT_RunIns): Updated.
db053ec9	2010-09-17T23:20:00	[truetype] Don't duplicate size->twilight structure to be freed. * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate FT_GlyphZoneRec size->twilight to be freed. If duplicated, FT_FREE() erases the duplicated pointers only and leave original pointers. They can cause the double-free crash when the burst errors occur in TrueType interpreter and free_buffer_in_size() is invoked repeatedly. See Savannah bug #31040 for detail.
afd89d30	2010-09-15T13:02:35	Make bytecode debugging with FontForge work again. * src/truetype/ttinterp.c (TT_RunIns): Don't call `free_buffer_in_size' in case of error if a debugger is active.
6abb9232	2010-09-14T09:02:10	Improve tracing messages. * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing message. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add tracing message. * src/truetype/ttgload.c (tt_loader_init): Add tracing message. * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if glyph doesn't fit into a small bitmap container.
5220ef58	2010-09-13T07:32:22	Fix minor issues reported by <muktha.narayan@wipro.com>. * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove redundant conditional check. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto. * src/cff/cffload.c (cff_encoding_load): Remove conditional check which always evaluates to `true'. * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points): Ditto. * src/truetype/ttinterp.c (Ins_IUP): Ditto. * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if value is already dereferenced. * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
0eb657b0	2010-08-31T13:29:05	[truetype] Decrease the trace level catching the interpreter error. * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level showing the error when the interpreter returns with an error, from FT_TRACE7() to FT_TRACE1().
29e044a4	2010-08-31T01:23:30	[truetype] Prevent bytecode reuse after the interpretation error. * src/truetype/ttinterp.c (free_buffer_in_size): New function to free the buffer allocated during the interpretation of this glyph. (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if an error occurs in the bytecode interpretation. The interpretation of invalid bytecode may break the function definitions and referring them in later interpretation is danger. By unsetting these flags, `fpgm' and `prep' tables are executed again in next interpretation. Fix Savannah bug #30798, reported by Robert Swiecki.
346f1867	2010-08-06T00:47:57	Fix Savannah bug #30657. * src/truetype/ttinterp.c (BOUNDSL): New macro. Change `BOUNDS' to `BOUNDSL' where appropriate. * src/truetype/ttinterp.h (TT_ExecContextRec): Fix type of `cvtSize'.
888cd184	2010-07-08T07:29:42	Fix Savannah bug #30361. * src/truetype/ttinterp.c (Ins_IUP): Fix bounds check.
a2d225e3	2010-07-01T11:37:09	[truetype] Protect against code range underflow. * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF): Don't allow negative IP values.
462ddb40	2010-07-01T11:28:43	[truetype] Add rudimentary tracing for bytecode instructions. * src/truetype/ttinterp.c (opcode_name) [FT_DEBUG_LEVEL_TRACE]: New array. (TT_RunIns): Trace opcodes.
370aea80	2010-06-08T08:37:11	Formatting.
6da023d1	2010-05-20T15:38:00	TrueType: Make FreeType ignore maxSizeOfInstructions in `maxp'. Acroread does the same. * src/truetype/ttgload.c (TT_Process_Composite_Glyph): Call `Update_Max' to adjust size of instructions array if necessary and add a rough safety check. (load_truetype_glyph): Save `loader->byte_len' before recursive call. * src/truetype/ttinterp.h, src/truetype/ttinterp.c (Update_Max): Declare it as FT_LOCAL.
a1151420	2009-08-01T00:32:18	truetype: Check invalid function number in IDEF instruction.
d1c23082	2009-08-01T00:32:17	truetype: Check invalid function number in FDEF instruction.
6dc27526	2009-08-01T00:32:15	truetype: Cast the numerical operands to 32-bit for LP64 systems.
3b56c4d3	2009-08-01T00:32:15	truetype: Cast the project vector to 32-bit for LP64 system.
c6788a38	2009-06-07T13:09:21	Fix some potential out-of-memory crashes. * src/base/ftobjs.c (ft_glyphslot_done): Check `slot->internal'. * src/base/ftstream.c (FT_Stream_ReleaseFrame): Check `stream'. * src/truetype/ttinterp.c (TT_New_Context): Avoid double-free of `exec' in case of failure.
1e5e7aa0	2009-01-25T16:27:04	Fix SCANCTRL handling in TTFs. Problem reported by Alexey Kryukov <anagnost@yandex.ru>. * src/truetype/ttinterp.c (Ins_SCANCTRL): Fix threshold handling.

ce8853af	2008-06-24T11:19:03	* src/truetype/ttinterp. (Ins_SCANTYPE): Don't check rendering mode. * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph, Draw_Sweep): No-dropout mode is value 2, not value 0. (Draw_Sweep): Really skip dropout handling for no-dropout mode.
5df5dbb7	2008-06-22T13:40:08	Enable access to the various dropout rules of the B&W rasterizer. Pass dropout rules from the TT bytecode interpreter to the rasterizer; temporarily this is enabled only if `USE_SCAN_CONVERSION_RULES' is defined. * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS, FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the OpenType specification. Fix mode 4 computation. (Render_Glyph, Render_Gray_Glyph): Handle new outline flags. * src/truetype/ttgload.c (TT_Load_Glyph) [USE_SCAN_CONVERSION_RULES]: Convert scan conversion mode to FT_OUTLINE_XXX flags. * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

(finally!) For most OpenType tables, `tt_face_load_xxxx' simply loads the table and `face->root' is set later in `sfnt_load_face'. Here, we try to make this work for _all_ tables. * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and then exit. Error handling or setting face->root is done later in `sfnt_load_face'. Pretty trace messages. * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. Mac bitmap-only fonts are not scalable. Check that `face->header.Units_Per_EM' is not zero. (LOAD_, LOADM_): Pretty trace messages. * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from `eblc'. * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c (load_format_20, load_format_25, tt_face_get_ps_name): Use face->max_profile.numGlyphs, instead of face->root.num_glyphs.

(tt_slot_init): New function to create extra points for the internal glyph loader. We then use it directly, instead of face's glyph loader, when loading glyph. * src/truetype/ttdriver.c: Use tt_slot_init for glyph slot initialization. (TT_Load_Glyph): Load flag dependencies are handled here. Return error if size is NULL. * src/truetype/ttgload.c: Heavy cleanup and refactor. (TT_Hint_Glyph): New funcion to hint a zone, prepared by caller. (TT_Process_Simple_Glyph): Use loader->pp's instead of recalculating. Use TT_Hint_Glyph. No need to save/restore loader->stream before/after TT_Vary_Get_Glyph_Deltas now. (TT_LOADER_SET_PP): New macro to calculate and set the four phantom points. (TT_Process_Composite_Component, TT_Process_Composite_Glyph, load_truetype_glyph): Refactor load_truetype_glyph into these three functions. Never set exec->glyphSize to 0. (close #13107) Forget glyph frame before calling TT_Process_Simple_Glyph. (TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into these three functions. Set various fields of `glyph' here, instead of in load_truetype_glyph and compute_glyph_metrics.
33febc0f	2004-10-09T07:07:43	* docs/CHANGES: Updated. Fix handling of NPUSHW if skipped in data stream. * src/truetype/ttinterp.c (opcode_length): Set value for NPUSHW to -2. (SkipCode, TT_RunIns): Use opcode_length value for computation of bytes to be skipped.
dea712b4	2004-08-07T15:08:33	`Activate' gray-scale specifing hinting within the TrueType bytecode interpreter. This is an experimental feature which should probably be made optional. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Move the code to set the pedantic_hinting flag to... (TT_Load_Glyph): Here. Set `grayscale' flag except for `FT_LOAD_TARGET_MONO'. * src/truetyep/ttinterp.c (Ins_GETINFO): Return MS rasterizer version 1.7. Return rotation and stretching info only if glyph is rotated or stretched, respectively. Handle grayscale info. * src/truetype/ttinterp.h (TT_ExecContextRec): Add `grayscale' member.
5ab41363	2004-07-18T07:15:18	* include/freetype/cache/ftcglyph.h, src/cache/ftcglyph.c: fixed a dangling pointer bug that happened in very rare cases: i.e. when a new family object was destroyed by an out-of-memory condition during a glyph node initialization. The function FTC_Cache_Lookup would flush the cache and restart the lookup with a bad pointer. * src/cache/ftcmanag.c: fixed a cache flushing bug
dfa46199	2004-03-05T09:26:24	* Jamfile, vms_make.com, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype/vcproj, include/freetype/ftmoderr.h: Add LZW module. * Jamfile.in: Removed. * docs/CHANGES: Updated. * include/freetype/internal/ftobjs.h: s/MIN/FT_MIN/, s/MAX/FT_MAX/, s/ABS/FT_ABS/. Updated all callers. * src/type1/t1load.c (parse_dict), src/pcf/pcfdrivr.c (PCF_Face_Init): Use FT_ERROR_BASE. Add support for PCF fonts compressed with LZW (extension .pcf.Z, created with `compress'). * include/freetype/config/ftoption.h, devel/ftoption.h (FT_CONFIG_OPTION_USE_LZW): New macro. * include/freetype/ftlzw.h: New file. * include/freetype/config/ftheader.h (FT_LZW_H): New macro for ftlzw.h. * src/lzw/: New files. src/pcf/pcfdrivr.c: Include FT_LZW_H.

b08fe2dc	2002-08-27T20:20:29	* massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
91db04cb	2002-04-01T14:25:28	* src/truetype/ttgload.c: 16bit fixes. (TT_Load_Simple_Glyph): Improve debug messages.

4b29d587	2002-03-25T17:02:26	removing compiler warnings
e459d742	2002-03-22T13:52:37	* 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..
b5713c54	2002-03-14T11:26:29	* include/freetype/internal/psglobals.h (removed), include/freetype/internal/pshints.h, src/pshinter/pshglob.h: removing obsolete file * include/freetype/internal/tttypes.h, include/freetype/internal/sfnt.h, src/base/ftnames.c, src/cff/cffdrivr.c, src/sfnt/.c, src/truetype/.c: updated SFNT/TrueType type definitions

d6a213f8

2011-01-31T18:51:07

[truetype] Improve handling of invalid references. * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference error codes only if pedantic hinting is active. At the same time, try to provide sane values which hopefully allow useful continuation. Exception to this is CALL and LOOPCALL – due to possible stack corruption it is necessary to bail out.

[truetype] Fix handling of MIRP instruction. Thanks to Greg Hitchcock who explained the issue. * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with `>' since the description in the specification is incorrect. This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 65 medium' at 15ppem.

46c371c2

2010-10-25T00:14:13

Replace "%lx" for memory address by "%p", LLP64 platforms. On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover the memory address (64-bit). Also the casts from the pointer type to long int should be removed to preserve the address correctly. * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". (End_Profile) Ditto. * src/truetype/ttinterp.c (Init_Context): Ditto.

0edf0986

2010-10-06T11:52:27

2010-09-17T23:20:00

[truetype] Don't duplicate size->twilight structure to be freed. * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate FT_GlyphZoneRec size->twilight to be freed. If duplicated, FT_FREE() erases the duplicated pointers only and leave original pointers. They can cause the double-free crash when the burst errors occur in TrueType interpreter and free_buffer_in_size() is invoked repeatedly. See Savannah bug #31040 for detail.

afd89d30

2010-09-15T13:02:35

29e044a4

2010-08-31T01:23:30

[truetype] Prevent bytecode reuse after the interpretation error. * src/truetype/ttinterp.c (free_buffer_in_size): New function to free the buffer allocated during the interpretation of this glyph. (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if an error occurs in the bytecode interpretation. The interpretation of invalid bytecode may break the function definitions and referring them in later interpretation is danger. By unsetting these flags, `fpgm' and `prep' tables are executed again in next interpretation. Fix Savannah bug #30798, reported by Robert Swiecki.

(finally!) For most OpenType tables, `tt_face_load_xxxx' simply loads the table and `face->root' is set later in `sfnt_load_face'. Here, we try to make this work for _all_ tables. * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and then exit. Error handling or setting face->root is done later in `sfnt_load_face'. Pretty trace messages. * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. Mac bitmap-only fonts are not scalable. Check that `face->header.Units_Per_EM' is not zero.

(TT_Process_Composite_Component, TT_Process_Composite_Glyph, load_truetype_glyph): Refactor load_truetype_glyph into these three functions. Never set exec->glyphSize to 0. (close #13107) Forget glyph frame before calling TT_Process_Simple_Glyph. (TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into these three functions.
