b38ca3cb | 2015-12-06 19:48:31 | [autofit] Typos. * src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_get_elem) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Make it compile. | |
|
facb79ab | 2015-12-06 19:34:59 | [autofit] Add support for Khmer script. We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and `Khmer symbols' (`khms', U+19E0-U+19FF). * src/autofit/afblue.dat: Add blue zone data for Khmer. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Khmer standard characters. * src/autofit/afranges.c: Add Khmer data. * src/autofit/afstyles.h: Add Khmer data. | |
|
24aa9c66 | 2015-12-06 18:52:41 | [autofit] Rewrite HarfBuzz interface to support character clusters. Scripts like Khmer have blue zones that can't be directly represented by Unicode characters. Instead, it is necessary to let HarfBuzz convert character clusters into proper glyph representation forms, then deriving the blue zone information from the resulting glyphs. * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by... * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new files, providing a new API to access HarfBuzz. The new API manages a HarfBuzz buffer with `af_shaper_buf_create' and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded string with function `af_shaper_get_cluster', and the resulting glyph data (indices, advance widths, vertical offsets) can be iteratively accessed with function `af_shaper_get_elem'. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/. (af_face_globals_compute_style_coverage): Updated. * src/autofit/afglocal.h: s/hbshim.h/afshaper.h/. * src/autofit/autofit.c: s/hbshim.c/afshaper.c/. * src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC): Updated. | |
|
de599941 | 2015-12-06 18:18:02 | [autofit] Prepare forthcoming changes. This makes it easier to control the commits. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy loop. No functional change. | |
|
f45c0bf9 | 2015-12-06 09:58:18 | [autofit] Use string of standard characters. This is more flexible; additionally, it would allow character clusters. * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated. (AF_ScriptClassRec): Replace `standard_char[123]' with `standard_charstring'. * src/autofit/afscript.h: Replace last three character arguments of the `SCRIPT' calls with a string parameter, holding the standard characters (in UTF-8 encoding) separated with spaces. * src/autofit/afglobal.c, src/autofit/afglobal.h, src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c (SCRIPT): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated. | |
|
a8a54c30 | 2015-12-05 13:26:44 | * src/autofit/afblue.dat: Separate blue zone characters with spaces. Another preparation for character cluster support. * src/autofit/afblue.c, src/autofit.afblue.h: Regenerated. | |
|
453722db | 2015-12-05 13:20:30 | * src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces. Instead, reduce multiple spaces to a single one. We need this later for supporting character clusters in `afblue.dat'. | |
|
f7e6d51a | 2015-12-05 13:08:45 | * src/autofit/afblue.hin (GET_UTF8_CHAR): Use `do...while(0)'. * src/autofit/afblue.h: Regenerated. | |
|
53696f03 | 2015-12-05 07:44:16 | * src/autofit/afwarp.c: s/INT_MIN/FT_INT_MIN/. | |

(section_title_header1, section_title_header2): ... these two strings. (HtmlFormatter::make_block_url, make_html_word, html_source_quote): Handle sections. (HtmlFormatter::section_enter): Updated to add `id' HTML attribute. | |
|
97b808fd | 2015-11-26 14:29:17 | [docmaker] Allow `foo[bar]' as identifier. We need this to handle equally named properties in different modules. * src/tools/docmaker/content.py (re_identifier), src/tools/docmaker/sources.py (re_crossref): Allow `foo[bar]'. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word, HtmlFormatter::index_exit, HtmlFormatter::section_enter, HtmlFormatter::block_enter): Handle `foo[bar]'. | |

|
68fb4789 | 2015-11-15 13:06:48 | * src/autofit/afhints.c (af_get_segment_index): Fix it. The old code was too simple, returning invalid values in most cases where a segment crosses the contour start. | |
|

|
6bda921d | 2015-11-02 06:53:48 | [ftfuzzer] Update README file. | |
|
bcf618b2 | 2015-11-02 06:50:49 | [ftfuzzer] Add support for multiple files (patch #8779). Currently, libFuzzer only supports mutation of a single file. We circumvent this problem by using an uncompressed tar archive as multiple-file input for the fuzzer. This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; a constructed tarball should contain a font file as the first element, and files to be attached as further elements. * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. (archive_read_entry_data, parse_data): New functions. (LLVMFuzzerTestOneInput): Updated. * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom mutator for libFuzzer that can mutate tarballs in a sensible way. | |

|
f1c93439 | 2015-10-22 10:11:23 | [cff] Avoid overflow/module arithmetic. This modifies the addition of subroutine number to subroutine bias from unsigned to signed, but does not change any results. * src/cff/cf2ft.c (cf2_initGlobalRegionBuffer, cf2_initLocalRegionBuffer): Change variable names from (unsigned) `idx' to (signed) `subrNum', since it is not an index until after the bias is added. * src/cff/cf2ft.h: Updated. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: Updated similarly. | |

|
58b61b6e | 2015-10-13 18:26:18 | [pcf] Quickly exit if font index < 0. Similar to other font formats, this commit makes the parser no longer check the whole PCF file but only the header and the TOC if we just want to get the number of available faces (and a proper recognition of the font format). * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated. Exit quickly if face_index < 0. * src/pcfread.c (pcf_load_font): Add `face_index' argument. Exit quickly if face_index < 0. * src/pcf/pcf.h: Updated. | |
|

This patch also contains various other improvements. * src/tools/ftfuzzer/ftfuzzer.cc: Add preprocessor guard to reject pre-C++11 compilers. (FT_Global): New class. Use it to provide a global constructor and destructor for the `FT_Library' object. (setIntermediateAxis): New function to select an (arbitrary) instance. (LLVMFuzzerTestOneInput): Loop over all faces and named instances. Also call `FT_Set_Char_Size'. | |
|
43a96eb2 | 2015-10-13 11:18:55 | [truetype] Refine some GX sanity tests. Use the `gvar' table size instead of the remaining bytes in the stream. * src/truetype/ttgxvar.h (GX_BlendRec): New field `gvar_size'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Set `gvar_size'. (ft_var_readpackedpoints, ft_var_readpackeddeltas: New argument `size'. (tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Updated. | |
|

 |
c14ae9c5 | 2015-10-10 22:28:26 | * src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix overflow (#46149). | |
|
8de39a79 | 2015-10-10 13:34:11 | [sfnt] Fix infinite loops with broken cmaps (#46167). * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next): Take care of border condidions (i.e., if the loops exit naturally). | |
|
da34673e | 2015-10-10 10:21:27 | [truetype] More sanity tests for GX handling. These tests should mainly help avoid unnecessarily large memory allocations in case of malformed fonts. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas): Check number of points against stream size. (ft_var_load_avar): Check `pairCount' against table length. (ft_var_load_gvar): Check `globalCoordCount' and `glyphCount' against table length. (tt_face_vary_cvt): Check `tupleCount' and `offsetToData'. Fix trace. (TT_Vary_Apply_Glyph_Deltas): Fix trace. Free `sharedpoints' to avoid memory leak. | |
