238245cd	2021-11-16T22:07:28	Fix clang++ warnings. * src/*: Initialize some variables to NULL.
80b13f57	2021-10-26T10:57:17	Formatting.
b5e003f1	2021-10-21T09:48:38	[cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up. Reportd as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts into locals and update the vstore counts immediately after each entry becomes free-able.

c78f78fa	2021-04-24T22:38:48	* src/cff/cffload.c (cff_index_get_pointers): s/FT_QALLOC/FT_ALLOC/.
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.
a6adb256	2020-12-02T14:15:07	* 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).
5abd252a	2020-11-20T15:24:42	[cff,cid,type1] Demote old engine for lack of CFF2. * src/cff/cffobjs.c (cff_iriver_init): Always default to Adobe engine. * src/cid/cidobjs.c (cid_driver_init): Ditto. * src/type1/t1objs.c (T1_Driver_Init): Ditto.
4f13a43a	2020-09-24T09:35:24	* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>.
53be1753	2020-07-28T07:33:40	Fix `-Wformat' compiler warnings. * src/: Fix format specifiers. builds/unix/ftsystem.c (FT_Stream_Open): Ditto.

a4434747	2020-06-20T05:31:34	[cff] Fix handling of `style_name == NULL' (#58630). * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails by returning NULL in `cff_face_init', `remove_style' is still called. This means that the NULL pointer is dereferenced, causing a crash.
f594ffdc	2020-06-19T18:55:49	[cff] Fix another two memory leaks (#58629). * src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create' fails to allocate one of the `internal->subfont' variables, make sure to free `internal->topfont' and any successfully allocated subfonts.
8ed5a247	2020-06-19T10:35:57	[cff, cid] Fix segfaults in case of error (#58621). * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c (cid_slot_done): If `ft_glyphslot_init' fails to allocate `internal', then the class' `done_slot' callback (called by `ft_glyphslot_done') must not dereference the pointer to `internal'.
575b78d9	2020-06-18T15:12:03	[cff] Fix memory leak (#58610). * src/cff/cffobjs.c (cff_size_init): When the call to `funcs->create' fails, make sure to free `internal'.
74cebeae	2020-06-19T03:41:12	* src/cff/cffload.c (cff_index_get_pointers): Rename `t' to `tbl'.
c8cd139c	2020-06-18T13:46:37	[cff] Free table upon error allocating other data (#58609). * src/cff/cffload.c (cff_index_get_pointers): When new_bytes fails to allocate, make sure to free the table. Do the same for both allocations if there is a later error.
16586859	2020-06-13T21:15:45	Remove redundant inclusion of `ft2build.h'. * /: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
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.
e5038be7	2020-01-19T17:05:19	Update all copyright notices.
4270e9f3	2019-11-27T11:38:45	Avoid more nullptr offset UBSan warnings (#57316). * src/base/ftoutln.c (FT_Outline_Transform): Bail on empty points. * src/cff/cffload.c (cff_subfont_load): Use `FT_OFFSET'. * src/psaux/psft.c (cf2_decoder_parse_substrings): Early out if `charstring_base' or `charstring_len' are null. * src/sfnt/ttload.c (tt_face_load_name): Use `FT_OFFSET'.
1e9229f0	2019-10-09T15:37:19	[cff] Fix FT_FACE_FLAG_GLYPH_NAMES for CFF2 based fonts (#57023). * src/cff/cffobjs.c (cff_face_init): Don't set FT_FACE_FLAG_GLYPH_NAMES for CFF2 based fonts.
78c02bc1	2019-06-10T23:09:49	[type1,type42] Use `const' for string literals. * include/freetype/internal/psaux.h (PS_Table_FuncsRec): Updated. * include/freetype/internal/t1types.h (T1_EncodingRec): Updated. * src/psaux/psobjs.[ch] (ps_table_add): Updated. * src/type1/t1load.c (T1_Open_Face, parse_encoding): Updated. * src/type42/t42objs.c (T42_Open_Face): Updated. * src/type42/t42parse.c (t42_parse_encoding): Updated. * src/cff/cffobjs.c (cff_face_init): Minor.
3ad1c93a	2019-04-06T06:37:42	Make `glyph_name' parameter to `FT_Get_Name_Index' a `const'. * include/freetype/freetype.h (FT_Get_Name_Index), include/freetype/internal/ftobjs.h (FT_Face_GetGlyphNameIndexFunc), include/freetype/internal/services/svgldict.h (FT_GlyphDict_NameIndexFunc), src/base/ftobjs.c (FT_Get_Name_Index), src/cff/cffdrivr.c (cff_get_name_index), src/sfnt/sfdriver.c (sfnt_get_name_index), src/type1/t1driver.c (t1_get_name_index), src/type42/t42drivr.c (t42_get_name_index): Add `const' to second argument.
6986ddac	2019-03-31T11:08:49	[cff] Fix boundary checks. 642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically allocated memory when parsing CFF files with the "old" engine. Bounds checks have never been updated, however, leading to pointless comparisons of pointers in some cases. This commit presents a solution for bounds checks in the CFF module with an extended logic for the "old" engine while staying as concise as possible for the "new" one. * src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and the additional field `t2_strings' within `CFF_ParserRec'. * src/cff/cffparse.c (cff_parser_within_limits): Move all boundary checks into this new function and update the rest of `cffparse.c' to use it. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12137

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. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cffcffdrivr.c (cff_set_mm_weightvector, cff_get_mm_weightvector): New functions. (cff_service_multi_masters): Register them. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated.

642bc759	2018-11-22T10:29:35	[cff] Fix memory overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9869 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10869 * src/cff/cffparse.c (destruct_t2s_item, cff_parser_run): Store evaluated T2 charstrings in separately allocated memory.
ba62f9d8	2018-10-29T21:11:36	[cff] Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10988 * src/cff/cffparse.c (cff_parser_run) [CFF_CONFIG_OPTION_OLD_ENGINE]: Use `NEG_LONG'.
912e174c	2018-10-07T09:28:52	A missing Unicode cmap is not a fatal error. This is a follow-up to the previous commit. * src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c (sfnt_load_face), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Implement it.

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.
76a52465	2018-09-03T09:08:47	/: s/PSNames/psnames/. Only tracing messages are affected.
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.
1937b557	2018-08-14T07:54:25	[cff] Fix missing error handling. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9865 * src/psaux/cffparse.c (cff_parser_run) [CFF_CONFIG_OPTION_OLD_ENGINE]: Don't ignore return value of `parse_charstrings_old'.

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.

f89c67f0	2017-10-07T13:10:53	[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance. (TT_Set_Var_Design): Use current named instance for default coordinates. * src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.

1df35d94	2017-10-04T22:46:36	[cff] Add support for `FSType'. * include/freetype/internal/cfftypes.h (CFF_FontRec): Add `font_extra' entry. * src/cff/cffdrivr.c (cff_ps_get_font_extra): New function to retrieve FSType info from the embedded PostScript data. (cff_service_ps_info): Register function. * src/cff/cffload.c (cff_font_done): Free `font_extra'.

ebb1735a	2017-09-25T08:26:57	Move `psdecode' into `psobjs'. As the former only contains a single procedure, move it into `psobjs' for simplicity. Also change the parameter order to the conventional one. * src/psaux/psdecode.c (ps_decoder_init): Moved to... * src/psaux/psobjs.c: ...Here. * src/psaux/psdecode.h, src/psaux/psobjs.h: Ditto. * include/freetype/internal/psaux.h (PSAux_ServiceRec): Update `ps_decoder_init' function signature. * src/cff/cffgload.c, src/cid/cidgload.c, src/type1/t1gload.c: Update calls. * src/psaux/psaux.c, src/psaux/psauxmod.c: Update includes. * src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRV_SRC): Update file references.

b00be9f6	2017-09-19T07:12:03	[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

[cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up.

[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance.

[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
