Werner Lemberg 20957721 2018-08-26T15:15:56 ChangeLog*: s/\t/ /.
Nikhil Ramakrishnan f87b7117 2018-08-26T17:46:25 * configure: Copy assets required by docwriter. Copy directory `docs/reference/markdown' when FreeType is compiled in a different directory. Fixes `make refdoc' if builddir != srcdir. Reported as http://lists.nongnu.org/archive/html/freetype-devel/2018-08/msg00083.html

Werner Lemberg 4738dcc4 2018-08-26T12:03:33 Minor tracing adjustments. * src/base/ftstream.c (FT_Stream_EnterFrame, FT_Stream_ExitFrame): Trace. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Remove tracing.
Werner Lemberg 6e339b8d 2018-08-26T11:59:02 [truetype] Avoid nested frames. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054 * src/truetype/ttgload.c (load_truetype_glyph): Don't use variable `opened_frame' to trace whether a frame must be closed at the end of function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which gets called for space glyphs) uses a frame by itself. Instead, close the frame after loading the header, then use another frame for the remaining part of the glyph later on. Also avoid calling `tt_get_metrics' twice under some circumstances.

Nikhil Ramakrishnan 195728d5 2018-08-25T12:17:30 * src/tools/docmaker: Remove `docmaker'. `Docmaker' has now upgraded to `docwriter', a pip package available at https://pypi.org/project/docwriter/
Nikhil Ramakrishnan 53c69ce0 2018-08-25T12:06:32 * docs/reference: Add resources for `docwriter'.

(TT_Load_Simple_Glyph): Use new macros to make code more readable. Remove useless adjustment of `outline->tags' elements.

Alexei Podtelezhnikov 3d4ab6ba 2018-08-08T00:09:16 [pcf] Massive unsigning (part 1). Unofficial specifications hesitate to use unsigned 32-bit integers.

Werner Lemberg 6e44d78c 2018-07-28T22:23:16 [type1] Avoid segfaults with `FT_Get_PS_Font_Value'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9610 * src/type1/t1driver.c (t1_ps_get_font_value): Protect against NULL.
Werner Lemberg c9edca8e 2018-07-27T10:44:01 [truetype] Make `TT_Set_MM_Blend' idempotent (#54388). * src/truetype/ttgxvar.c (tt_set_mm_blend): Correctly set `face->doblend' if the current call to the function yields the same blend coordinates as the previous call.
Werner Lemberg d277bfc9 2018-07-27T09:15:43 [psaux, type1]: More tracing improvements. * src/psaux/psintrp.c (cf2_interpT2CharString): Trace skipped outline commands. * src/psaux/t1decode.c (t1_decoder_parse_charstring): Fix missing case. (t1_decoder_parse_metrics): Make tracing output more compact. * src/type1/t1gload.c (T1_Compute_Max_Advance): Be less verbose. (T1_Get_Advances): Add tracing.
Werner Lemberg 6e6acdcb 2018-07-26T07:22:18 Document FT_Module_Class's `module_interface' field.
Werner Lemberg 8ed53468 2018-07-25T22:07:22 [psaux, type1] Trace PostScript dictionaries and other things. The tracing of /Encoding, /Subrs, and /Charstrings is rudimentary right now. * src/psaux/psobjs.c (ps_parser_load_field, ps_parser_load_field_table): Add tracing calls. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make tracing output more compact. * src/type1/t1gload.c (T1_Compute_Max_Advance, T1_Get_Advances): Add tracing messages. * src/type1/t1load.c (parse_blend_axis_types, parse_blend_design_positions, parse_blend_design_map, parse_weight_vector, t1_load_keyword, t1_parse_font_matrix, parse_encoding, parse_subrs, parse_charstrings, T1_Open_Face): Add tracing calls. * src/type1/t1objs.c (T1_Face_Init): Add tracing call. * src/sfnt/sfobjs.c (sfnt_init_face): Make tracing message more verbose.
Werner Lemberg 580c94d8 2018-07-25T07:03:07 Fix minor ASAN run-time warnings. * src/base/ftutil.c (ft_mem_alloc, ft_mem_realloc): Only call `FT_MEM_ZERO' if we actually have a buffer. (ft_mem_dup): Only call `ft_memcpy' if we actually have a buffer.
Alexei Podtelezhnikov 4b97ab98 2018-07-24T23:01:34 [build] Fortify dllexport/dllimport attributes (#53969,#54330). We no longer use predefined _DLL, which can be defined for static builds too with /MD. We use DLL_EXPORT and DLL_IMPORT instead, following libtool convention. * CMakeLists.txt [WIN32], builds/windows/vc2010/freetype.vcxproj: Define DLL_EXPORT manually. * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in, builds/vms/ftconfig.h, builds/windows/vc2010/index.html, src/base/ftver.rc: /_DLL/d, s/FT2_DLLIMPORT/DLL_IMPORT/.
Werner Lemberg d8ea52de 2018-07-24T23:03:06 [type1] Check relationship between number of axes and designs. For Multiple Masters fonts We don't support intermediate designs; this implies that number_of_designs == 2 ^^ number_of_axes Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9557 * src/type1/t1load.c (T1_Open_Face): Ensure above constraint. (T1_Get_MM_Var): Remove now redundant test.
Hin-Tak Leung 71e29fe1 2018-07-24T10:04:23 [truetype] Match ttdebug's naming of instruction mnemonics. * src/truetype/ttinterp.c: The form used in ttdebug, "MDRP[G,B,W,?]", etc., is slightly more readable than "MDRP[00,01,02,03]".
