535c67dd	2021-10-25T22:38:05	[mm] Tolerate missing Blend dictionary entries In a Multiple Master font, the Blend dictionary must contain valid Private, FontInfo, and FontBBox. The current code will error if any of these are present and invalid, but will not error and will provide uninitialized data if the Blend dictionary exists but does not contain one of these entries. This change reverts to the older behavior of treating any missing entries as containing all zero data and not returning an error. In the future it may be best to keep track of when these are actually initialized and error if they are not. * src/type1/t1load.c (t1_allocate_blend): Zero initiailize.
65be4b21	2021-10-21T09:55:28	[mm] Delay setting blend weight and design position. Previously the `blend->weight_vector`, `blend->default_weight_vector`, and `blend->design_pos` were set early to allocated but uninitialized memory under the assumption that the memory would eventually be initialized. However, it is possible that some of the required keywords may not actually be present, leaving the memory uninitialized. This is different from a present but invalid table, which would produce an error. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions.
1029eb93	2021-10-11T22:25:14	[type1] Revert to signed size for binary data. Recently introduced and reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=39838 * src/type1/t1load.c (read_binary_data): Reject negative size. (parse_subrs, parse_charstrings): Use customary signed size.

ec9e5114	2021-04-23T14:03:03	[cff,type1,type42] s/FT_ALLOC/FT_QALLOC/ for initialized buffers. * src/cff/cffload.c (cff_index_get_pointers, cff_index_get_name): Do not zero out the buffer. * src/cff/cffdrivr.c (cff_ps_get_font_info): Ditto. * src/type1/t1load.c (parse_subrs, parse_charstrings, parse_blend_axis_types): Ditto. * src/type1/t1parse.c (T1_New_Parser, T1_Get_Private_Dict): Ditto. * src/type42/t42parse.c (t42_parser_init): Ditto.
d924a66a	2021-02-04T07:44:06	* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`. This ensures good logging output, with all lines having a proper prefix (if requested). This is a continuation of a similar patch from 2020-12-02, which missed some locations.
b6e8a712	2021-01-17T07:18:48	Update all copyright notices.
53be1753	2020-07-28T07:33:40	Fix `-Wformat' compiler warnings. * src/: Fix format specifiers. builds/unix/ftsystem.c (FT_Stream_Open): Ditto.
e1339133	2020-06-08T13:31:55	Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. /: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

78a1e695	2018-11-27T22:24:06	[type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. For multiple master fonts, common usage (in Postscript) is to modify the WeightVector of an existing font instance, this addition supports that use. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, FT_Get_MM_WeightVector): New API functions. * include/freetype/internalservices/svmm.h (FT_Set_MM_WeightVector_Func, FT_Get_MM_WeightVector_Func): New function types. (MultiMasters): Add `set_mm_weightvector' and `get_mm_weightvector' members.

f56830ed	2018-10-20T07:27:47	Avoid endless loop while tracing (#54858). * src/type1/t1load.c (parse_buildchar): Guard tracing stuff with FT_DEBUG_LEVEL_TRACE.
a9af6914	2018-09-25T09:10:09	Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. /: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
a0dd16fb	2018-08-15T18:13:17	Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. / (FT_COMPONENT): Updated.

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.
cc333390	2018-06-24T06:22:48	New base function `FT_Matrix_Check' (#54019). * src/base/ftcalc.c (FT_Matrix_Check): New base function to properly reject degenerate font matrices. * include/freetype/internal/ftcalc.h: Updated. * src/cff/cffparse.c (cff_parse_font_matrix), src/cid/cidload.c (cid_parse_font_matrix), src/type1/t1load.c (t1_parse_font_matrix), src/type42/t42parse.c (t42_parse_font_matrix): Use `FT_Matrix_Check'.
9ac9060d	2018-06-03T09:01:17	[GSoC] src/.: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
3b8f1680	2018-04-04T20:26:08	[cff, type1] Sanitize `BlueFuzz' and `BlueShift'.

40db4a99	2017-11-27T22:17:41	Allow (again) encoding vectors with more than 256 elements (#52464). In version 2.6.1, this has been disallowed to better reject malformed fonts; however, this restriction was too strong. This time, we only take the first 256 elements into account, since encoding arrays are always accessed with a 8bit integer, according to the PostScript Language Reference. * src/type1/t1load.c (parse_encoding): Implement it.

[mm] Tolerate missing Blend dictionary entries In a Multiple Master font, the Blend dictionary must contain valid Private, FontInfo, and FontBBox. The current code will error if any of these are present and invalid, but will not error and will provide uninitialized data if the Blend dictionary exists but does not contain one of these entries. This change reverts to the older behavior of treating any missing entries as containing all zero data and not returning an error. In the future it may be best to keep track of when these are actually initialized and error if they are not. * src/type1/t1load.c (t1_allocate_blend): Zero initiailize.

[mm] Delay setting blend weight and design position. Previously the `blend->weight_vector`, `blend->default_weight_vector`, and `blend->design_pos` were set early to allocated but uninitialized memory under the assumption that the memory would eventually be initialized. However, it is possible that some of the required keywords may not actually be present, leaving the memory uninitialized. This is different from a present but invalid table, which would produce an error. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions.

Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected.

Various compiler warning fixes. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use `logical not' operator instead of negation. The idea is that `~' returns exactly the data type enforced by the cast to a pointer (be it 32bit or 64bit or whatever), while a negative integer has not this flexibility. * src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto. * src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto. * src/type/t1load.c (T1_Get_MM_Var): Ditto. (parse_blend_axis_types): Use cast. * src/bdf/bdflib.c (_bdf_readstream): Use cast.
