fb5268cf	2015-09-28T02:01:43	[base] Fix a leak by broken sfnt-PS or resource fork (#46028). open_face_from_buffer() frees passed buffer if valid font is not found. But if copying to the buffer is failed, the allocated buffer should be freed within the caller. * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free the buffer `sfnt_ps' if an error caused before calling open_face_from_buffer(). (Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if an error caused before calling open_face_from_buffer();

2439c515	2015-09-25T16:54:28	[type1] Protect against invalid number of glyphs (#46029). * src/type1/t1load.c (parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream.
5339c75e	2015-09-24T13:39:44	[sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs.
c409eb18	2015-09-24T12:39:38	[base, sfnt] Better checks for invalid cmaps (1/2). * src/base/ftobjs.c (FT_Get_Char_Index): Don't return out-of-bounds glyph indices. (FT_Get_First_Char): Updated. * src/sfnt/ttcmap.c (tt_cmap6_char_next): Don't return character codes greater than 0xFFFF. (tt_cmap8_char_index): Avoid integer overflow in computation of glyph index.

e982f5b7	2015-09-21T23:07:22	[base] Check too long POST and sfnt resource (#45919). * src/base/ftbase.h (FT_MAC_RFORK_MAX_LEN): Maximum length of the resource fork for Mac OS. The resource fork larger than 16 MB can be written but could not be handled correctly, at least in Carbon routine. See https://support.microsoft.com/en-us/kb/130437 * src/base/ftobjs.c (Mac_Read_POST_Resource): No need `0x' for `%p' formatter. * src/base/ftbase.c (Mac_Read_POST_Resource): Check the fragment and total size of the concatenated POST resource before buffer allocation. (Mac_Read_sfnt_Resource): Check the declared size of sfnt resource before buffer allocation. * src/base/ftmac.c (read_lwfn, FT_New_Face_From_SFNT): Check the total resource size before buffer allocation.
730b6d74	2015-09-19T12:41:12	[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.
cb7a5122	2015-09-19T07:58:03	[pcf] Improve `FT_ABS' fix from 2015-09-17 (#45999). * src/pcf/pcfread.c (pcf_load_font): Do first the cast to FT_Short, then take the absolute value. Also apply FT_ABS to `height'.
f28c95c4	2015-09-17T19:30:26	[type42] Fix memory leak (#45989). * src/type42/t42parse.c (t42_parse_charstrings): Allow only a single `CharStrings' array.
4942c2bb	2015-09-17T17:56:53	[psaux] Fix memory leak (#45986). * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_MM_BBOX>: Free `temp' in case of error.

bd0438a4	2015-09-16T18:05:43	Minor fixes for some clang warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Cast, possible missing initialization. * src/truetype/ttgload.c (TT_Process_Composite_Component): Cast.
19cb1127	2015-09-15T08:52:36	[type1, type42] Fix memory leaks (#45966). * src/type1/t1load.c (parse_blend_axis_types): Handle multiple axis names. (parse_blend_design_map): Allow only a single design map. (parse_encoding): Handle multiple encoding vectors. * src/type42/t42parse.c (t42_parse_encoding): Handle multiple encoding vectors.

3ea0d2c6	2015-09-13T23:19:34	* src/base/ftcalc.c (FT_MulFix) [FT_LONG64]: Improve.
7962a15d	2015-09-14T00:38:26	[type1] Fix another potential buffer overflow (#45955). * src/type1/t1parse (T1_Get_Private_Dict): Assure that check for `eexec' doesn't exceed `limit'.
ff7d6404	2015-09-13T23:53:16	Replace `mkinstalldirs' with AC_PROG_MKDIR_P. * builds/unix/mkinstalldirs: Removed, no longer needed. * builds/unix/configure.raw: Call `AC_PROG_MKDIR_P'. Update pwd call for `$INSTALL'. * builds/unix/unix-def.in (MKINSTALLDIRS): Use `@MKDIR_P@'. * autogen.sh: Updated.
3df92aa0	2015-09-13T09:21:52	[winfonts] Check alignment shift count for resource data (#45938). * src/winfonts/winfnt.c (fnt_face_get_dll_font): Implement it.
e3058617	2015-09-13T08:41:43	[type1] Fix potential buffer overflow (#45923). * src/type1/t1parse.c (T1_Get_Private_Dict): Assure `cur' doesn't point to end of file buffer.
e40e8b33	2015-09-13T08:05:50	[gzip] Fix access of small compressed files (#45937). * src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak. (ft_gzip_get_uncompressed_file): Correct byte order while reading unsigned long value. Without this change, the whole optimization of accessing small files in `FT_Stream_OpenGzip' is never executed! As a consequence, access to PCF files in general (which are normally small files) should be much improved now as originally intended.
db5a4a9a	2015-09-12T08:32:55	[psaux] Fix potential buffer overflow (#45922). * src/psaux/psobjs.c (ps_parser_skip_PS_token): If a token is enclosed in balanced expressions, ensure that the cursor position doesn't get larger than the current limit.

822acb02	2015-09-09T07:59:10	* src/base/ftcalc.c (FT_CeilFix, FT_FloorFix): Normalize. This commit makes the functions behave as expected, this is, rounding towards plus or minus infinity.
5578199a	2015-09-09T07:52:17	Minor documentation corrections.
b002f688	2015-09-07T13:47:36	* src/smooth/ftgrays.c (gray_render_line): Simplify clipping.
5a6dc872	2015-09-04T23:14:46	[raster,smooth] Microoptimizations. * src/raster/ftraster.c (Insert_Y_Turn, Finalize_Profile_Table, Beziier_Up, ): Use do-while loops. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line, gray_convert_glyph): Ditto.
a9f6f04e	2015-09-04T22:28:13	[autofit] Missing piece.
d3cba0ed	2015-09-04T10:28:53	[autofit] Redesign code ranges (2/2). This commit adds two fallback scripts (`latb', `latp') and implements support for the no-base character ranges introduced in the previous commit. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `script_uni_nobase_ranges' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and `latp' fallback scripts. * src/autofit/afblue.dat: Add blue zones for Latin subscript and superscript fallback scripts. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base characters.

(af_face_globals_compute_style_coverage): Handle new style flag. * src/autofit/aflatin.c (af_latin_hints_apply): Handle new style flag. * src/autofit/afranges.h (SCRIPT): Use it to export no-base ranges.
696b7126	2015-09-04T10:10:59	[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.
8cbbcf6b	2015-09-03T06:47:30	[autofit] Pass glyph index to hinting function. No functionality change yet. * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Pass glyph index. * src/autofit/afcjk.c, src/autofit/afcjk.h (af_cjk_hints_apply), src/autofit/afdummy.c (af_dummy_hints_apply), src/autofit/afindic.c (af_indic_hints_apply), src/autofit/aflatin.c (af_latin_hints_apply), src/autofit/aflatin2.c (af_latin2_hints_apply), src/autofit/afloader.c (af_loader_load_g): Updated.
40103a3a	2015-08-31T08:51:52	[autofit] Code clean-up. * src/autofit/afglobal.h (AF_STYLE_MASK): New macro. (AF_STYLE_UNASSIGNED): Use AF_STYLE_MASK for definition. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Updated.
87c81f04	2015-08-30T10:35:21	[autofit] Make glyph style array use 16bit values. * include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use `FT_UShort' for `map' field. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage, af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h (af_get_coverage): Use FT_UShort for `glyph_styles' array. * src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to 16 bits.

d0d7ee04	2015-08-14T14:30:58	* builds/unix/detect.mk (CONFIG_SHELL): Don't handle it (#44261).
14d6b5d7	2015-08-13T15:22:17	[truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks. (sfnt_load_face): Updated. * src/truetype/ttobjs.c (tt_face_init) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting the style name. * src/base/ftobjs.c (open_face_from_buffer, open_face_PS_from_sfnt_stream): Updated. * src/bdf/bdfdrivr.c (BDF_Face_Init): Updated. * src/cff/cffload.c (cff_font_load): Updated. * src/cff/cffobjs.c (cff_face_init): Make function exit early for pure CFF fonts if `font_index < 0'. Updated. * src/cid/cidobjs.c (cid_face_init): Updated. * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated. * src/pfr/pfrobjs.c (pfr_face_init): Updated. * src/type1/t1objs.c (T1_Face_Init): Updated. * src/type42/t42objs.c (T42_Face_Init): Updated. * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init): Updated. * docs/CHANGES: Updated.
4afc0a54	2015-08-12T23:51:02	Comment typos.
4a466865	2015-08-12T23:45:40	[type1,cff,cid] Streamline font matrix application. * src/type1/t1gload.c (T1_Load_Glyph): Directly modify advances only if font matrix is not trivial. * src/cff/cffgload.c (cff_slot_load): Ditto. * sff/cid/cidgload.c (cid_slot_load_glyph): Ditto for advances and the entire outline.
7ebe6ac8	2015-08-11T06:47:25	[builds/unix] Minor. * builds/unix/configure.raw: s/lib{priv,staticconf}/libs{priv,staticconf}/ for orthogonality with similarly named uppercase variables.

bd75a517	2015-08-08T08:39:45	[type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.
e5f44693	2015-08-08T07:45:03	[type42] Minor clean-up. * src/type42/t42parse.c (t42_parse_font_matrix): Remove unused variable.
fd70512e	2015-08-06T21:49:08	[type42] Parse FontMatrix according to specifications. * src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix does not need scaling by 1000. Units_per_EM are taken from the embedded TrueType.
ff406e2e	2015-08-06T07:34:50	[autofit] Improve Arabic hinting. Problem reported by Titus Nemeth <tn@tntypography.eu> (by using ttfautohint). * src/autofit/afblue.dat: Add neutral blue zone for the tatweel character. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
98e8e999	2015-08-06T00:06:14	[truetype] Clean up types. * src/truetype/ttobjs.c (TT_Size): Move declaration from here. * include/freetype/internal/tttypes.h (TT_Size): ... to here. (TT_LoaderRec): Switch to appropriate types for `face' and `size'. * src/truetype/ttgload.c: Remove corresponding type casts. * src/truetype/ttsubpix.c: Ditto.
15e2a4f7	2015-08-05T21:53:50	[autofit] Improve recognition of flat vs. rounded segments. Lower the flatness threshold from upem/8 to upem/14, making the auto-hinter accept shorter elements. Synchronize flat/round stem selection algorithm with blue zone code. * src/autofit/aflatin.c (FLAT_THRESHOLD): New macro. (af_latin_metrics_init_blues): Use it. (af_latin_hints_compute_segments): Collect information on maximum and minimum coordinates of `on' points; use this to add a constraint for the flat/round decision similar to `af_latin_metrics_init_blues'.
eb22ef26	2015-08-04T06:50:04	Another left-shift bug (#45681). * src/base/ftobjs.c (IsMacBinary): Only accept positive values for `dlen'.
7e6c321a	2015-08-03T23:26:13	[base] Fix `ft_corner_orientation'.

[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.

[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.

[truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks.

[type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.

[base] Fix `ft_corner_orientation'. Remove casting from `FT_Long' to `FT_Int' that might change the sign of the return value and make it faster too. * src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay with 32-bit arithmetic when safe. Use plain math on 64-bit systems. * src/pshinter/pshalgo.c: Remove old unused code.
