Алексей Подтележников 7c4ac3cb 2010-11-28T08:23:40 [ftsmooth]: Minor code simplification. * src/smooth/ftgrays (gray_render_cubic): Do only one comparison instead of two.
Johnson Y. Yan 9073e7ce 2010-11-26T11:58:08 [truetype] Better multi-threading support. * src/truetype/ttinterp.c (TT_Load_Context): Reset glyph zone references.
John Tytgat ed7d1a59 2010-11-23T19:30:38 * src/psaux/t1decode.c (t1_decoder_parse_charstring): Expand start_point, check_points, add_point, add_point1, close_contour macros. Remove add_contour macro. Return error code from t1_builder_start_point and t1_builder_check_points when there was one (instead of returning 0).
Werner Lemberg 9871b849 2010-11-22T19:30:41 Some formatting and improvements of comments.
suzuki toshiya 9f5dd61b 2010-11-23T02:47:10 [truetype] Identify the tricky fonts by cvt/fpgm/prep checksums. Some Latin TrueType fonts are still expected to be unhinted. Fix Savannah bug #31645. * src/truetype/ttobjs.c (tt_check_trickyness): Divided to... (tt_check_trickyness_family): this checking family name, and (tt_check_trickyness_sfnt_ids): this checking cvt/fpgm/prep. (tt_get_sfnt_checksum): Function to retrieve the sfnt checksum for specified subtable even if cleared by lazy PDF generators. (tt_synth_sfnt_checksum): Function to calculate the checksum.
Werner Lemberg ec4372f5 2010-11-18T20:34:22 [truetype] Fix `loca' handling for inconsistent number of glyphs. Reported by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>. * src/truetype/ttpload.c (tt_face_load_loca): While sanitizing, handle case where `loca' is the last table in the font.
Werner Lemberg fa764cf8 2010-11-18T13:08:52 [sfnt] Ignore all errors while loading `OS/2' table. Suggested by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>. * src/sfnt/sfobjs.c (sfnt_load_face): Do it.
Johnson Y. Yan b70d8a0e 2010-11-18T10:36:59 [type1] Fix matrix normalization. * src/type1/t1load.c (parse_font_matrix): Handle sign of scaling factor.
Werner Lemberg f689bf7d 2010-11-18T10:28:16 [type1]: Improve guard against malformed data. Based on a patch submitted by Johnson Y. Yan <yinsen_yan@foxitsoftware.com> * src/type1/t1load.c (read_binary_data): Check `size'.
Werner Lemberg 05012ad9 2010-11-17T11:47:53 [sfnt] While tracing, output table checksums also. * src/sfnt/ttload.c (tt_face_load_font_dir): Do it.
suzuki toshiya ac09390a 2010-11-04T23:26:11 [UVS] Fix find_variant_selector_charmap(), Savannah bug #31545. Since 2010-07-04, find_variant_selector_charmap() returns the first cmap subtable always under rogue-compatible configuration, it causes NULL pointer dereference and make UVS-related functions crashed. * src/base/ftobjs.c (Fix find_variant_selector_charmap): Returns UVS cmap correctly.
suzuki toshiya b72e0460 2010-11-04T23:09:05 [UVS] Remove non-essential pointer checking in previous commit.
suzuki toshiya e891e4d6 2010-11-04T21:53:11 [UVS] Stabilizes UVS supporting functions against non-UVS fonts. UVS supporting functions assume the variation handler functions are valid. When a font without cmap format 14 is given, these function pointers are left as NULL, so calling these functions causes NULL pointer dereference. * src/base/ftobjs.c (FT_Face_GetCharVariantIndex): Check the pointer FT_CMap_Class->char_var_index before calling it. (FT_Face_GetCharVariantIsDefault): Check the pointer FT_CMap_Class->char_var_default before calling it. (FT_Face_GetVariantSelectors): Check the pointer FT_CMap_Class->variant_list before calling it. (FT_Face_GetVariantsOfChar): Check the pointer FT_CMap_Class->charvariant_list before calling it. (FT_Face_GetCharsOfVariant): Check the pointer FT_CMap_Class->variantchar_list before calling it.
Alexei Podtelezhnikov 6aee6909 2010-11-02T16:01:03 [ftsmooth] Improve rendering. * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3, cubic deviations have been estimated _after_ UPSCALE, whereas conic ones have been evaluated _before_ UPSCALE, which produces inferior rendering results. Fix this. Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has been tested with demo images sent to the mailing list. See http://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html and later mails in this thread.
Werner Lemberg 6a96bbe2 2010-10-28T08:51:15 [ftraster] Minor fixes. Reported by Tom Bishop <wenlin@wenlin.com>. * src/raster/ftraster.c (ULong): Remove unused typedef. (TWorker): Remove unused variable `precision_mask'.
Werner Lemberg f0987abd 2010-10-28T08:33:28 [ftraster] Fix rendering. Problem reported by Tom Bishop <wenlin@wenlin.com>; see thread starting with http://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv since the involved multiplication exceeds 32 bits.
suzuki toshiya 875439cf 2010-10-25T15:43:01 Revert a change of `_idx' type in FTC_CACHE_LOOKUP_CMP(). * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert the type of `_idx' from FT_PtrDist (by previous change) to original FT_UFast, to match with FT_CacheRec.
suzuki toshiya 3512a712 2010-10-25T02:07:52 [cache] Change the hash types to FT_PtrDist. On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) variables are inappropriate to calculate hash values from the memory address (64-bit). The hash variables are extended from FT_ULong to FT_PtrDist and new hashing macro functions are introduced. The hash values on 16-bit memory platforms are changed, but ILP32 and LP64 are not changed. The hash value in the cache subsystem is not reverted to the memory address, so using signed type FT_PtrDist is safe. * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash function to replace FTC_FACE_ID_HASH() for portability. * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace FTC_FACE_ID_HASH() by _FTC_FACE_ID_HASH(). * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. * src/cache/ftccache.h (FTC_NodeRec): The type of the member `hash' is changed from FT_UInt32 to FT_PtrDist. * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the argument `hash' is changed from FT_UInt32 to FT_PtrDist. (FTC_Cache_NewNode): Ditto. * src/cache/ftccache.c (ftc_cache_add): Ditto. (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto. * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto. * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto. * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type of the internal variable `hash' is changed to FT_PtrDist from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto. (FTC_SBitCache_Lookup): Ditto. (FTC_SBitCache_LookupScaler): Ditto. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto. * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto. Also the type of the internal variable `_idx' is changed to FT_PtrDist from FT_UInt32 for better pointer calculation.
suzuki toshiya b8b498f2 2010-10-25T00:35:59 Change the type of FT_MEM_VAL() from FT_ULong to FT_PtrDist. On LLP64 platforms (e.g. Win64), unsigned long (32-bit) cannot cover the memory address (64-bit). FT_MEM_VAL() is used for hashing only and not dereferred, so using signed type FT_PtrDist is safe. * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the return value from FT_ULong to FT_PtrDist. (ft_mem_table_resize): The type of hash is changed to FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
suzuki toshiya 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.
Werner Lemberg 34d61e86 2010-10-15T20:44:15 Fix thinko in spline flattening. FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and replace it everywhere with ONE_PIXEL/8.
suzuki toshiya 463dddad 2010-10-13T17:20:27 [raccess] Skip unrequired resource access rules by Darwin VFS. When a resource fork access rule by Darwin VFS could open the resource fork but no font is found in it, the rest of rules by Darwin VFS are skipped. It reduces the warnings of the deprecated resource fork access method by recent Darwin kernel. Fix MacPorts ticket #18859: http://trac.macports.org/ticket/18859 * src/base/ftobjs.c (load_face_in_embedded_rfork): When FT_Stream_New() returns FT_Err_Cannot_Open_Stream, it means that the file is possible to be fopen()-ed but zero-sized. Also there is a case that the resource fork is not zero-sized, but no supported font exists in it. If a rule by Darwin VFS falls into such cases, there is no need to try other Darwin VFS rules anymore. Such cases are marked by vfs_rfork_has_no_font. If it is TRUE, the Darwin VFS rules are skipped.
suzuki toshiya c081a4a9 2010-10-13T17:05:42 [raccess] Grouping resource access rules based on Darwin VFS. MacOS X/Darwin kernel supports a few tricky methods to access a resource fork via ANSI C or POSIX interface. Current resource fork accessor tries all possible methods to support all kernels. But if a method could open a resource fork but no font is found, there is no need to try other methods older than tested method. To determine whether the rule index is for Darwin VFS, a local function ftrfork.c::raccess_rule_by_darwin_vfs() is introduced. To use this function in ftobjs.c etc but it should be inlined, it is exposed by ftbase.h. * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify the rules to access the resource fork. (raccess_guess_rec): New structure to bind the rule function and rule enum type. (FT_Raccess_Guess): The list of the rule functions is replaced by (raccess_guess_table): This. This is exposed to be used by other intra module functions. (raccess_rule_by_darwin_vfs): A function to return a boolean if the rule specified by the rule index is based on Darwin VFS.
suzuki toshiya 4b718714 2010-10-13T16:21:59 Prevent to open a FT_Stream for zero-sized file on non-Unix. builds/unix/ftsystem.c prevents to open an useless stream from zero-sized file and returns FT_Err_Cannot_Open_Stream, but the stream drivers for ANSI C, Amiga and VMS return useless streams. For cross-platform consistency, all stream drivers should act same. * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened file is zero, FT_Err_Cannot_Open_Stream is returned. * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto. * src/vms/ftsystem.c (FT_Stream_Open): Ditto.
Werner Lemberg 59eb9f8c 2010-10-12T07:49:17 Fix Savannah bug #31310. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against invalid `runcnt' values.
Chris Liddell bc4ed48e 2010-10-08T18:40:18 Fix Savannah bug #31275. * src/sfnt/ttpost.c: Include FT_INTERNAL_DEBUG_H.
Ed 4afa9d74 2010-10-08T12:05:40 Typo.
Werner Lemberg 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'.
Werner Lemberg 3987b15e 2010-10-02T11:46:19 Fix Savannah bug #31088 (sort of). * src/sfnt/ttload.c (tt_face_load_maxp): Always allocate at least 64 function entries.
Werner Lemberg 0e6fc091 2010-10-02T09:05:46 [smooth] Fix splitting of cubics for negative values. Reported by Róbert Márki <gsmiko@gmail.com>; see http://lists.gnu.org/archive/html/freetype/2010-09/msg00019.html. * src/smooth/ftgrays.c (gray_render_cubic): Fix thinko.
suzuki toshiya 5edc2f33 2010-10-01T08:15:55 Fix Savannah bug #31040. * src/truetype/ttinterp.c (free_buffer_in_size): Remove. (TT_RunIns): Updated.
suzuki toshiya d2b8b8db 2010-09-20T19:06:23 [sfnt] Make error message filling NULL names less verbose. * src/sfnt/ttpost.c (load_format_20): Showing 1 summary message when we fill `post' names by NULL, instead of per-entry message.
Graham Asher e0a9a933 2010-09-20T09:29:23 [smooth] Fix and improve spline flattening. This fixes the flattening of cubic, S-shaped curves and speeds up the handling of both the conic and cubic arcs. See the discussions on the freetype-devel mailing list in late August and September 2010 for details. * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro. (TWorker): Remove `conic_level' and `cubic_level' elements. (gray_render_conic): Simplify algorithm. (gray_render_cubic): New algorithm; details are given in the code comments. (gray_convert_glyph): Remove heuristics.
Werner Lemberg d38ba0c9 2010-09-19T20:51:19 Minor fixes. * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]' is `FT_UShort'. (cff_index_access_element): Don't use additions in comparison. * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type `FT_Long'. Don't use additions in comparison. Improve tracing messages. (load_format_25, load_post_names): Make `post_limit' of type `FT_Long'.
suzuki toshiya 73aa20ca 2010-09-20T01:30:38 [cff] Truncate the element length at the end of the stream. See Savannah bug #30975. * src/cff/cffload.c (cff_index_access_element): `off2', the offset to the next element is truncated at the end of the stream to prevent invalid I/O. As `off1', the offset to the requested element has been checked by FT_STREAM_SEEK(), `off2' should be checked similarly.
suzuki toshiya d2d843a0 2010-09-20T01:28:17 [cff] Ignore CID > 0xFFFFU. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if greater than 0xFFFFU. CFF font spec does not mention about maximum CID in the font, but PostScript and PDF spec define that maximum CID is 0xFFFFU.
suzuki toshiya a0f43f20 2010-09-20T01:26:56 [cff] Make trace message in cff_charset_load() verbose. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_load): Report the original `nleft' and truncated `nleft'.
suzuki toshiya b3e1954d 2010-09-20T01:22:34 [cff] Correct `max_cid' from CID array length to max CID. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_compute_cids): Don't increment max_cid after detecting max CID. The array CFF_Charset->cids is allocated by max_cid + 1. (cff_charset_cid_to_gindex): Permit CID is less than or equal to CFF_Charset->max_cid. * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is calculated as CFF_Charset->max_cid + 1.
suzuki toshiya 643d49df 2010-09-20T01:07:57 [truetype] Sanitize the broken offsets in `loca'. * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the offset to the requested entry in `glyf' exceeds the end of the table, return offset=0, length=0. If `pos2', the offset to the next entry in `glyf' exceeds the end of the table, truncate the entry length at the end of `glyf' table. See Savannah bug #31040.
suzuki toshiya 900e7e0c 2010-09-20T01:03:36 [sfnt] Prevent overrunning in `post' table parser. * src/sfnt/ttpost.c (load_post_names): Get the length of `post' table and pass the limit of `post' table to load_format_20() and load_format_25(). (load_format_20): Stop the parsing when we reached at the limit of `post' table. If more glyph names are required, they are filled by NULL names. See Savannah bug #31040.
suzuki toshiya 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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'.
suzuki toshiya 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().
suzuki toshiya 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.
Werner Lemberg 12cf0316 2010-08-29T11:02:24 [ftraster] Pacify compiler. * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is not used.
Werner Lemberg 0e95b3d1 2010-08-29T10:46:26 [cff] Allow SIDs >= 65000. * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20: The threshold for SIDs is not applicable here. I misinterpreted the `SID values 65000 and above are available for implementation use' sentence in the CFF specification. Problem reported by Ivan Ninčić <inincic@pdftron.com>.
suzuki toshiya 0eb9b1f5 2010-08-28T21:41:16 Force hinting when the font lacks its familyname. In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt stream may lack `name' table because they are not required. Hinting for nameless fonts is safer for PDFs including embedded Chinese fonts. Written by David Bevan, see: http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html http://lists.freedesktop.org/archives/poppler/2010-August/006310.html * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by nameless font is given, TRUE is returned to enable hinting.
suzuki toshiya 8b05b5d8 2010-08-28T21:16:26 Register yet another tricky TrueType font. * src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?', a Kaishu typeface paired with `HuaTianSongTi?' by Huatian Information Industry.
Teijo Kinnunen ebaeb642 2010-08-17T07:40:55 Fix Savannah bug #30788. * src/cache/ftccache.c (FTC_Cache_Clear): Check `cache->buckets' for NULL too.
Werner Lemberg a205b3ca 2010-08-10T02:59:12 Try to fix Savannah bug #30717 (and probably #30719 too). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Add another overflow test for `width' and `height'.
Werner Lemberg ba95440c 2010-08-06T20:07:36 Minor doc fixes, formatting.
suzuki toshiya 44524158 2010-08-07T01:46:56 Fix Savannah bug #30648. * src/base/ftobjs.c (FT_Done_Library): Specify the order of font drivers in face closing process. Type42 faces should be closed before TrueType faces, because a Type42 face refers another internal TrueType face which is created from sfnt[] array on the memory.
Yuriy Kaminskiy c9de9cbd 2010-08-06T08:20:28 [raster] Fix valgrind warning. * src/raster/ftraster.c (Decompose_Curve) <default>: Access point[0] only if we don't hit `limit'.
suzuki toshiya 81f3472c 2010-08-06T14:11:54 Fix Savannah bug #30658. * src/base/ftobjs.c (Mac_Read_POST_Resource): Check the total length of collected POST segments does not overrun the allocated buffer.
Werner Lemberg 223cb1b5 2010-08-06T06:55:09 [cff] Add comment to clarify current implementation of `pop' operator.
Werner Lemberg 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'.
Werner Lemberg c06da1ad 2010-08-05T23:15:26 Fix Savannah bug #30656. * src/type42/t42parse.c (t42_parse_sfnts): Protect against negative string_size. Fix comparison.
suzuki toshiya d9b3e394 2010-08-05T17:10:32 [cff] Don't use any values in decoder after parsing error. * src/cff/cffgload.c (cff_slot_load): Skip the evaluations of the values in decoder, if cff_decoder_parse_charstrings() returns any error.
Werner Lemberg 45a3c76b 2010-08-04T15:54:55 Fix Savannah bug #30644. * src/base/ftstream.c (FT_Stream_EnterFrame): Fix comparison.
Suzuki, Toshiya (鈴木俊哉) 11d65e8a 2010-08-04T14:43:29 [cff] Improve stack overflow test. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Check stack after execution of operations too.
Werner Lemberg fe3433c7 2010-07-18T18:41:47 Add reference counters and to FT_Library and FT_Face objects. * include/freetype/freetype.h (FT_Reference_Face): New function. * include/freetype/ftmodapi.h (FT_Rererence_Library): New function. * include/freetype/internal/ftobjs.h (FT_Face_InternalRec, FT_LibraryRec): New field `refcount'. * src/base/ftobjs.c (FT_Open_Face, FT_New_Library): Handle `refcount'. (FT_Reference_Face, FT_Reference_Library): Implement new functions. (FT_Done_Face, FT_Done_Library): Handle `refcount'. * docs/CHANGES: Updated.
Werner Lemberg 2de6b8a3 2010-07-17T13:39:50 [cff] Final try to fix `hintmask' and `cntrmask' limit check. Problem reported by Tobias Wolf <towolf@gmail.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Sigh. I'm apparently too silly to fix this correctly in less than three tries.
Werner Lemberg c8f5b98b 2010-07-12T21:13:22 Remove C++ warnings. */*: Initialize pointers where necessary to make g++ happy.

suzuki toshiya b8ca6de3 2010-07-09T11:36:00 Fix Savannah bug #30373. Too serious check of errors by `FT_CMap_New' since 2010-07-04 is fixed. Reported by Tor Andersson. * include/freetype/fterrdef.h (PSnames_Err_No_Unicode_Glyph_Name): New error code to indicate the Unicode charmap synthesis failed because no Unicode glyph name is found. * src/psnames/psmodule.c (ps_unicodes_init): Return PSnames_Err_No_Unicode_Glyph_Name when no Unicode glyph name is found in the font. * src/cff/cffcmap.c (cff_cmap_unicode_init): Return CFF_Err_No_Unicode_Glyph_Name when no SID is available. * src/type1/t1objs.c (T1_Face_Init): Proceed if `FT_CMap_New' is failed by the lack of Unicode glyph name. * src/type42/t42objs.c (T42_Face_Init): Ditto. * src/cff/cffobjs.c (cff_face_init): Ditto.

Werner Lemberg 2dc76a46 2010-07-05T06:40:02 [cff] Next try to fix `hintmask' and `cntrmask' limit check. Problem reported by malc <av1474@comtv.ru>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: It is possible that there is just a single byte after the `hintmask' or `cntrmask', e.g., a `return' instruction.
suzuki toshiya 0ae32718 2010-07-04T20:14:18 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 when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE. * src/base/ftobjs.c (find_unicode_charmap): When Unicode charmap 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.

suzuki toshiya b2ea64bc 2010-07-02T18:16:02 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.
Werner Lemberg c2dabdee 2010-07-02T01:27:49 Merge branch 'master' of git.sv.gnu.org:/srv/git/freetype/freetype2 Conflicts: ChangeLog
suzuki toshiya 5ef20c8c 2010-07-01T18:39:04 Initial fix for Savannah bug #30306. * src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen' the length of fragment declared in the POST fragment header and prevent an underflow in length calculation. Some fonts set the length to zero in spite of the exist of following 16bit `type'. Reported by Robert Swiecki.
Werner Lemberg 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.
