bd37b847	2023-05-08T06:46:55	* src/psaux/t1cmap.c: Signature fixes.
1a4c18f7	2023-04-10T15:30:43	Align `char_next` return types. This is mostly cosmetic because FT_UInt and FT_UInt32 are likely identical. * src/sfnt/ttcmap.c, src/cff/cffcmap.c, src/psaux/t1cmap.c, src/psnames/psmodule.c, include/freetype/internal/service/svpcsmap.h, src/pfr/pfrcmap.c, src/winfonts/winfnt.c (*_char_next): return FT_UInt.
d399657f	2023-02-26T20:18:54	* src/*: Replace leading underscores with trailing ones in dummy variables. This is to avoid clang warnings.
663486a7	2023-02-08T20:56:19	Fix `FT_LOCAL` and `FT_LOCAL_DEF` tags.
ac5babe8	2023-02-08T19:36:10	Fix 'fall-through' warning messages. Modern compilers get more insistent on that... * include/freetype/internal/compiler-macros.h (FALL_THROUGH): Define. * src/: Use it instead of `/ fall through */` comments.
65f85237	2023-01-17T09:18:25	Update all copyright notices.
0bcb664d	2022-12-20T16:38:39	[psaux] Delay the upem validity assertion. Fixes #1194. * src/psaux/psft.c (cf2_getUnitsPerEm): Remove the upem assert. (cf2_checkTransform): Assert the upem validity after checking the scale.
de8f14a8	2022-09-30T23:25:02	* src/psaux/pshints.c (cf2_hintmap_insertHint): Fix midpoint computation. Replace '(start + end) / 2' with 'start + (end - start) / 2' to avoid overflow. Fixes #1180.
2adb810c	2022-09-30T17:00:10	* src/psaux/pshints.c (cf2_hintmap_build): Improve debugging output.

87989a14	2022-03-31T07:43:41	Fix clang++ warnings. * src/base/ftglyph.c (ft_svg_glyph_prepare), src/base/ftobj.c (ft_glyphslot_init), src/cache/ftccmap.c (ftc_cmap_node_new), src/cache/ftcimage.c (FTC_INode_New), src/lzw/ftlzw.c (FT_Stream_OpenLZW), src/psaux/psobjs.c (ps_parser_load_field), src/pshinter/pshglob.c (psh_globals_new), src/sfnt/ttsvg.c (tt_face_load_svg_doc): Initialize variables used for allocation. * src/sdf/ftsdf.c (split_sdf_conic, split_sdf_cubic): Change type of `max_splits` to FT_UInt. (sdf_generate_bounding_box): Add cast.
034e5dbf	2022-02-22T20:37:43	[psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259
8e39e42e	2022-02-02T11:35:14	[psaux] Revise `PS_Table` handling. The old impleemntation was not using `FT_REALLOC`, buing too careful with the offset rebasing. It shoudl be safe to rely on the base movements. * src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine into... (ps_table_realloc): ... this function based on `FT_REALLOC`.

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.
4eee1340	2020-05-18T09:16:12	Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.

f2b64583	2019-07-04T14:04:52	[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it.

9159128a	2019-05-29T07:45:54	Silence gcc 7's fall-through warnings in `switch' blocks. Instead of an intentionally missing `break' statement there must be a comment line containing `fall through' (and nothing else) right before the next `case' statement. See https://stackoverflow.com/questions/45129741/gcc-7-wimplicit-fallthrough-warnings-and-portable-way-to-clear-them

6a4718a3	2019-03-05T17:25:19	Fix use of uninitialized memory. * src/psaux/psintrp.c (cf2_interpT2CharString): The call to `cf2_arrstack_setCount' may fail because the allocator ran out of memory. When this happens the stack is still written to before the error condition is checked. This means that FreeType writes outside of allocated memory. This commit moves the error check prior to the stack assignment, hence the function now properly returns with an error condition.

All of the Type 1 path building is done with code common to the revised CFF engine, with the exception of closepath, which was still calling ps_builder_close_contour(), thus previously cached segments were not always written to the path, and glyph corruption, or even invalid outlines were possible. * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: Switch to calling `cf2_glyphpath_closeOpenPath'.

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.

[psaux] Full bounds check for OtherSubr 19. It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with `blend->num_designs` set to 2, and the user supplied `idx` to be large (for example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds check overflows in a well defined manner, allowing for an invalid call to `memcpy`. In addition, it is possible to call OtherSubr 19 with `decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes the bounds check (it is logically always fine to copy nothing starting at index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is undefined behavior (even if `count` is zero). * src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that `blend->num_designs` can be copied to `decoder->buildchar[idx]`. Also avoid passing NULL to `ft_memcpy`. Bug: https://crbug.com/1299259

[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it.
