Werner Lemberg 93fdf4eb 2015-12-10T11:52:08 Formatting.
Werner Lemberg bbe84ed9 2015-12-10T09:33:41 [autofit] Remove redundant code. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Do it.
Werner Lemberg 5330e3de 2015-12-10T08:32:58 [autofit] Minor.
Werner Lemberg dd305f31 2015-12-09T21:00:33 [autofit] Thinko. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Don't count empty blue zones (bug introduced 2015-12-06).
Werner Lemberg 0164d934 2015-12-09T20:04:18 [autofit] Introduce subscript top blue zones. This feature is mainly for Khmer: The idea is to avoid a clash between the top of subscript glyphs and the bottom of normal baseline glyphs. This only works for character clusters mapped to multiple glyphs. * src/autofit/afblue.dat: Add subscript top blue zone for Khmer. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE, AF_LATIN_BLUE_SUB_TOP): New macros. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new blue zone property. Update tracing messages. (af_latin_metrics_scale_dim): Handle new blue zone property. (af_latin_hints_compute_blue_edges): Updated.
Werner Lemberg f02e1df7 2015-12-09T14:45:30 [autofit] Fix tracing message. * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Display inactive blue zones also.
Werner Lemberg c13526e6 2015-12-08T09:48:50 * src/autofit/afblue.dat: Add more Khmer clusters. Some fonts have incorrect ligatures; we need more samples to get a good mean value. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
Werner Lemberg b38ca3cb 2015-12-06T19:48:31 [autofit] Typos. * src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_get_elem) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Make it compile.
Werner Lemberg facb79ab 2015-12-06T19:34:59 [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.
Werner Lemberg 24aa9c66 2015-12-06T18:52:41 [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.
Werner Lemberg de599941 2015-12-06T18:18:02 [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.
Werner Lemberg f45c0bf9 2015-12-06T09:58:18 [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.
Werner Lemberg a8a54c30 2015-12-05T13:26:44 * 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.
Werner Lemberg 453722db 2015-12-05T13:20:30 * 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'.
Werner Lemberg f7e6d51a 2015-12-05T13:08:45 * src/autofit/afblue.hin (GET_UTF8_CHAR): Use `do...while(0)'. * src/autofit/afblue.h: Regenerated.
Werner Lemberg 53696f03 2015-12-05T07:44:16 * src/autofit/afwarp.c: s/INT_MIN/FT_INT_MIN/.
Werner Lemberg 5b05bc66 2015-12-01T12:09:02 [type1] Avoid dangling pointer (#46572). * src/type1/t1afm.c (T1_Read_Metrics): Properly reset `face->afm_data'.
Werner Lemberg 4679bf83 2015-11-28T19:05:36 Fix C++ compilation. * src/autofit/afloader.c: Include FT_INTERNAL_CALC_H. * src/truetype/ttgload.c (load_truetype_glyph): Pacify compiler.

Werner Lemberg 98afe3f5 2015-11-28T11:58:49 [docmaker] Allow references to section names. In the reference, we show the section's title enclosed in single quotes. * src/tools/docmaker/formatter.py (Formatter::__init__): Collect section names as identifiers. * src/tools/docmaker/tohtml.py (section_title_header): Split into... (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.
Werner Lemberg 97b808fd 2015-11-26T14:29:17 [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]'.

See https://bugs.freedesktop.org/show_bug.cgi?id=92981 for the reasoning. * include/freetype/ftlcdfil.h (FT_LcdFilter): New value `FT_LCD_FILTER_LEGACY1'. * src/base/ftlcdfil.c (FT_Library_SetLcdFilter): Use it.
Werner Lemberg 68fb4789 2015-11-15T13:06:48 * 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.
Werner Lemberg 94cacac5 2015-11-15T04:45:42 * src/bdf/bdflib.c (bdf_load_font): Fix small memory leak (#46439).
Werner Lemberg 75722f89 2015-11-11T09:55:16 [cff, autofit] Switch off stem darkening by default. * src/autofit/afmodule.c (af_autofitter_init), src/cff/cffobjs.c (cff_driver_init): Do it.
Jan Alexander Steffens (heftig) ccd3188a 2015-11-10T22:33:45 Allow native CFF hinter in FT_RENDER_MODE_LIGHT.

(af_loader_compute_darkening): New function. * src/autofit/afloader.h: Updated.
Nikolaus Waxweiler 37c401ac 2015-11-02T09:32:26 [autofit] Add functions to get standard widths for writing systems. We need the computed standard horizontal and vertical widths for the emboldening calculation. This method provides a convenient way to extract it from writing-system-specific metrics structures, which all script definitions must implement. * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New function type. (AF_WritingSystemClassRec): New member `style_metrics_getstdw'. (AF_DEFINE_WRITING_SYSTEM_CLASS): Updated. * src/autofit/afcjk.c (af_cjk_get_standard_width): New function.

(af_autofitter_init): Initialize them.
Werner Lemberg 6bda921d 2015-11-02T06:53:48 [ftfuzzer] Update README file.
Werner Lemberg bcf618b2 2015-11-02T06:50:49 [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.

Werner Lemberg 009cc150 2015-10-31T17:52:56 [sfnt] Handle infinite recursion in bitmap strikes (#46344). * src/sfnt/ttsbit.c (TT_SBitDecoder_LoadFunc, tt_sbit_decoder_load_bitmap, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_png): Add argument for recursion depth. (tt_sbit_decoder_load_compound): Add argument for recursion depth. Increase recursion counter for recursive call. (tt_sbit_decoder_load_image): Add argument for recursion depth. Check recurse depth. (tt_face_load_sbit_image): Updated.

(PFR_SIZE): [!PFR_CONFIG_NO_CHECKS]: Define to PFR_CHECK_SIZE. * src/pfr/pfrload.c (pfr_log_font_count): Check `count'. (pfr_extra_item_load_kerning_pairs): Remove tracing message. (pfr_phy_font_load): Use PFR_CHECK_SIZE where appropriate. Allocate `chars' after doing a size checks. * src/pfr/pfrsbit.c (pfr_load_bitmap_bits): Move test for invalid bitmap format to... (pfr_slot_load_bitmap): ... this function. Check bitmap size.

Werner Lemberg 6a19a7d3 2015-10-26T15:40:22 [truetype] Fix sanitizing logic for `loca' (#46223). * src/truetype/ttpload.c (tt_face_load_loca): A thinko caused an incorrect adjustment of the number of glyphs, most often using far too large values.
Werner Lemberg 7f00fa64 2015-10-25T10:59:59 [autofit] Improve tracing. * src/autofit/afhints.c (af_print_idx, af_get_segment_index, af_get_edge_index): New functions. (af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'. Add segment and edge index for each point. Slightly change printing order of some elements. Don't print `-1' but `--' for missing elements. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove unnecessary `|', `[', and `]'. Don't print `-1' but `--' for missing elements.

Werner Lemberg f1c93439 2015-10-22T10:11:23 [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.
Werner Lemberg 59ae73fe 2015-10-22T09:26:00 [cid] Better check of `SubrCount' dictionary entry (#46272). * src/cid/cidload.c (cid_face_open): Add more sanity tests for `fd_bytes', `gd_bytes', `sd_bytes', and `num_subrs'.

Werner Lemberg 24a1fcdf 2015-10-15T21:50:15 [truetype] Add TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES (#46208). * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES): New configuration macro. * src/truetype/ttinterp.c (MAX_RUNNABLE_OPCODES): Removed. (TT_RunIns): Updated.
Werner Lemberg 837ad9d4 2015-10-15T21:15:45 * src/truetype/ttinterp.c (TT_RunIns): Fix bytecode stack tracing. The used indices were off by 1.

Werner Lemberg 58b61b6e 2015-10-13T18:26:18 [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.
Werner Lemberg bdb56bba 2015-10-13T11:51:13 [ftfuzzer] Handle TTCs and MM/GX variations. 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'.
Werner Lemberg 43a96eb2 2015-10-13T11:18:55 [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.
Werner Lemberg 052f6c56 2015-10-13T08:24:32 [truetype] Another GX sanity test. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Check `tupleCount'. Add tracing message.
Werner Lemberg 7ef0d866 2015-10-13T08:14:20 [truetype] Fix memory leak for broken GX fonts (#46188). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix scope of deallocation.
Werner Lemberg f96094ee 2015-10-13T07:13:56 [truetype] Fix commit from 2015-10-10. * src/truetype/ttgxvar.c (ft_var_load_gvar): Add missing error handling body to condition.
Werner Lemberg 4f7f6f6e 2015-10-11T07:55:25 [sfnt] Improve extraction of number of named instances. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check number of instances against `fvar' table size.
Alexei Podtelezhnikov c14ae9c5 2015-10-10T22:28:26 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix overflow (#46149).
Werner Lemberg 8de39a79 2015-10-10T13:34:11 [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).
Werner Lemberg da34673e 2015-10-10T10:21:27 [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.
