2fb8eda5	2023-06-01T19:38:36	/: Remove many function pointer casts. In C it is undefined behavior to call a function through a function pointer of a different type. This is now detected by the Control Flow Integrity Sanitizer. All known issues have already been fixed. Prevent any accidental re-introduction by removing function pointer casts when defining services. The services will call the service functions through the function pointers on the service. As a result the functions must have the same type so there should be no need to cast. Removing the casts allows compilers to warn about assignment to an incompatible function pointer type.
563f4011	2023-05-07T08:50:44	* src/type1/t1load.c: Signature fixes.
7cc5dfa2	2023-05-07T07:10:23	* src/type1/*: Clean up interface. Ensure that all driver functions use the signature of the service or driver. This avoids pointer mismatches, which are technically undefined behaviour. Recent compilers are more picky in catching them as part of Control Flow Integrity tests.
c8a24209	2023-04-27T11:40:46	[truetype] Fix PostScript name handling for variation fonts. A variation font's PostScript name of a named instance is usually different from the PostScript name of an unnamed instance. However, if a change between a named instance and an unnamed instance with exactly the same design axis values happened, it was possible that the PostScript name wasn't correctly updated. This commit reorganizes the code to handle this issue within the top-level API functions, using a new service to trigger recomputation of the PostScript name. * include/freetype/internal/services/svmm.h (FT_Construct_PS_Name_Func): New typedef. (FT_Service_MultiMasters): New field `construct_ps_name`. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/base/ftmm.c (FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Call `mm->construct_ps_name` to handle `postscript_name`. (FT_Set_Named_Instance): Call `mm->construct_ps_name` to handle `postscript_name`. Use shortcut. * src/cff/cffdrivr.c (cff_construct_ps_name): New function. (cff_service_multi_masters): Updated. * src/truetype/ttgxvar.c (tt_set_mm_blend): Don't handle `postscript_name`. (TT_Set_MM_Blend): Simplify. (TT_Set_Named_Instance): Return -1 if axis values haven't changed. Don't set `face_index`. (tt_construct_ps_name): New function. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. * src/type1/t1driver.c (t1_service_multi_masters): Updated. * src/type1/t1load.c (T1_Set_MM_Blend): Simplify.
6713b1e4	2023-04-26T12:03:04	[truetype] Fix deactivation of variation font handling. According to the documentation, the functions `FT_Set_Named_Instance`, `FT_Set_MM_Design_Coordinates`, `FT_Set_Var_Design_Coordinates`, and `FT_Set_Var_Blend_Coordinates` can unset the `FT_FACE_FLAG_VARIATION` flag. (The same is true for `FT_Set_MM_WeightVector` but this information was accidentally omitted from the documentation.) However, if a call of these functions didn't change the axis values this could fail because internal shortcuts exited too early. This commit reorganizes the code to handle `FT_FACE_FLAG_VARIATION` in the top-level API functions, also taking care of the issue at hand. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_MM_WeightVector, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Handle `FT_FACE_FLAG_VARIATION`. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design, TT_Set_Named_Instance) Don't handle `FT_FACE_FLAG_VARIATION`. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_WeightVector, T1_Set_MM_Design): Ditto. * src/cff/cffobjs.c (cff_face_init): Use `FT_Set_Named_Instance` instead of low-level functions. * src/truetype/ttobjs.c (tt_face_init): Ditto.

The Type1 problems was reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=50057.
90795210	2022-06-15T16:07:22	[type1] Directly search for eexec in private dict This code originally just searched for `eexec`. This was later modified to check that the `eexec` found is valid (not in a string or comment). This was done by searching for `eexec` as before and then, for each `eexec` found, searching from the beginning using the correct parsing to see if the `eexec` was still found. If the private dictionary is large and contains many copies of `eexec` which are not valid, the initial part of the private dictionary is scanned once for each, potentially leading to n^2 parsing time. Instead of finding an initial `eexec` and then re-parsing to discover if it is valid, drop the initial search for `eexec` and just parse to find a valid `eexec`. This is strictly faster since the validation must happen anyway and avoids restarting from the beginning each time an `eexec` is found in the data. * src/type1/t1parse.c (T1_Get_Private_Dict): avoid n^2 parsing Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1328883

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.

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.

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.
95149592	2018-05-02T20:27:48	Remove FT_CONFIG_OPTION_PIC and related code. / [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this preprocessor symbol. /: Replace `XXX_GET' macros (which could be either a function in PIC mode or an array in non-PIC mode) with `xxx' arrays. * include/freetype/internal/ftpic.h, src/autofit/afpic.c, src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h, src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h, src/pshinter/pshpic.c, src/pshinter/pshpic.h, src/psnames/pspic.c, src/psnames/pspic.h, src/raster/rastpic.c, src/raster/rastpic.h, src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c, src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h: Removed.

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.
7e23568b	2017-10-12T18:13:22	[type1, cid] Add hinting engine switch. Implement property service in `type1' and `cid' drivers to allow switching between FreeType or Adobe hinting engine when both are available. * src/cid/cidriver.c (cid_property_{set,get}, cid_services), src/type1/t1driver.c (t1_property_{set,get}, t1_services): Add Properties service. * src/cid/cidobjs.c (cid_driver_init), src/type1/t1objs.c (T1_Driver_Init): Add default property values.

It is disabled by default. * devel/ftoption.h, include/freetype/config/ftoption.h (T1_CONFIG_OPTION_OLD_ENGINE): New macro. * include/freetype/internal/psaux.h (PS_Decoder): Remove unused field. * include/freetype/internal/psaux.h, src/cid/cidgload.c (cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c (ps_builder_add_point), src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode, t1_decoder_parse_glyph, t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h, src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround relevant code with macro. Minor code changes.
78df3c27	2017-10-12T18:13:08	Extract width parsing from Type 1 parser. Duplicate the fast advance width calculations from the old parser. This is to facilitate adding options for compiling out the old parser. * src/psaux/t1decode.{c,h} (t1_decoder_parse_metrics): New function. * include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry `parse_metrics'. * src/psaux/psauxmod.c: Set the new entry. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Separate conditional for selecting engine.
e9ef538a	2017-10-07T12:57:11	Make `FT_Set_Named_Instance' work. * src/cff/cffdrivr.c (cff_set_instance): New function.

af03d1ea	2017-10-01T09:23:42	[smooth,type1] Formatting, whitespace.
6e7da50b	2017-09-25T08:29:38	Documentation fixes.
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.
93e3cffd	2017-09-25T08:08:21	Change subfont synthesis for CID fonts. Change `t1_make_subfont' to take in the Private dict record as an argument. This is because Type 1 and CID font records in FreeType have this in different places. * src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to `FT_Face' so that CID is also accepted. Take `PS_Private' as an argument and let caller figure out where the Private dict actually is. Update references. * include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update declaration. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update call.

283ef285	2017-09-25T06:54:16	Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags.
6eb03f8f	2017-09-25T06:49:41	Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call.
7e185dcd	2017-09-25T06:40:32	Allow `type1' module to use the Adobe engine. Add the callback and some conditionals to switch between the two engines. * include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Change function declarations. * src/psaux/psauxmod.c (T1_Decoder_FuncsRec): Register the callbacks. * src/psaux/psobjs.c (ps_builder_add_point): Add conditionals for number conversion. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add code to choose which renderer to use. * src/cid/cidgload.c (cid_load_glyph): Update call. * src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update includes.
97704b15	2017-09-25T06:33:28	Add Adobe engine configuration. Use the previously changed PS_Driver in type1 module to store hinting engine configuration. * include/freetype/ftt1drv.h: New file. Duplicate and rename config options from CFF. * include/freetype/config/ftheader.h (FT_TYPE1_DRIVER_H): New macro. * src/type1/t1driver.c (t1_driver_class): Update declaration. * src/type1/t1objs.c: Include FT_TYPE1_DRIVER_H. (T1_Driver_Init): Update code.
d23affe1	2017-09-25T06:22:52	Reorganize object fields. Make some fields more generic, so that we can access them the same way regardless of Type 1 or CFF. * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' to `FT_Face'. Remove unused fields. * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. Add some asserts to guard against casting `T1_Face' as `TT_Face'. * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow `CFF_GlyphSlot', so that we can pretend they are the same in the interpreter. * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): Updated with above changes.
79e3789f	2017-06-14T07:51:04	* src/winfonts/winfnt.c (FNT_Face_Init): Don't set active encoding. FreeType only sets a default active encoding for Unicode.
1ea34322	2017-06-03T06:52:13	[cff, truetype] Integer overflows. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2047 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2057 * src/cff/cf2hints.c (cf2_hintmap_map): Use OVERFLOW_SUB_INT32. * src/truetype/ttinterp.c (Ins_ADD): Use OVERFLOW_ADD_LONG. (Ins_SUB): Use OVERFLOW_SUB_LONG. (Ins_NEG): Use NEG_LONG.
5412d886	2017-04-22T12:48:50	Introduce `FT_Size_InternalRec' structure. We are going to extend this later on. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): New structure with a single field `module_data'. * src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of `FT_Size' structure. * src/cff/cffgload.c (cff_builder_init, cff_decoder_prepare): Use `size->internal->module_data' instead of `size->internal'. * src/cff/cffobjs.c (cff_size_done): Deallocate `module_data'.

*/*: Remove many function pointer casts. In C it is undefined behavior to call a function through a function pointer of a different type. This is now detected by the Control Flow Integrity Sanitizer. All known issues have already been fixed. Prevent any accidental re-introduction by removing function pointer casts when defining services. The services will call the service functions through the function pointers on the service. As a result the functions must have the same type so there should be no need to cast. Removing the casts allows compilers to warn about assignment to an incompatible function pointer type.

[truetype] Fix PostScript name handling for variation fonts. A variation font's PostScript name of a named instance is usually different from the PostScript name of an unnamed instance. However, if a change between a named instance and an unnamed instance with exactly the same design axis values happened, it was possible that the PostScript name wasn't correctly updated. This commit reorganizes the code to handle this issue within the top-level API functions, using a new service to trigger recomputation of the PostScript name. * include/freetype/internal/services/svmm.h (FT_Construct_PS_Name_Func): New typedef.

[truetype] Fix deactivation of variation font handling. According to the documentation, the functions `FT_Set_Named_Instance`, `FT_Set_MM_Design_Coordinates`, `FT_Set_Var_Design_Coordinates`, and `FT_Set_Var_Blend_Coordinates` can unset the `FT_FACE_FLAG_VARIATION` flag. (The same is true for `FT_Set_MM_WeightVector` but this information was accidentally omitted from the documentation.) However, if a call of these functions didn't change the axis values this could fail because internal shortcuts exited too early. This commit reorganizes the code to handle `FT_FACE_FLAG_VARIATION` in the top-level API functions, also taking care of the issue at hand. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_MM_WeightVector, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Handle `FT_FACE_FLAG_VARIATION`. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design, TT_Set_Named_Instance) Don't handle `FT_FACE_FLAG_VARIATION`. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_WeightVector, T1_Set_MM_Design): Ditto. * src/cff/cffobjs.c (cff_face_init): Use `FT_Set_Named_Instance` instead of low-level functions. * src/truetype/ttobjs.c (tt_face_init): Ditto.

[type1] Directly search for eexec in private dict This code originally just searched for `eexec`. This was later modified to check that the `eexec` found is valid (not in a string or comment). This was done by searching for `eexec` as before and then, for each `eexec` found, searching from the beginning using the correct parsing to see if the `eexec` was still found. If the private dictionary is large and contains many copies of `eexec` which are not valid, the initial part of the private dictionary is scanned once for each, potentially leading to n^2 parsing time. Instead of finding an initial `eexec` and then re-parsing to discover if it is valid, drop the initial search for `eexec` and just parse to find a valid `eexec`. This is strictly faster since the validation must happen anyway and avoids restarting from the beginning each time an `eexec` is found in the data. * src/type1/t1parse.c (T1_Get_Private_Dict): avoid n^2 parsing Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1328883

[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.

[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.

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.

2017-09-25T08:08:21

Change subfont synthesis for CID fonts. Change `t1_make_subfont' to take in the Private dict record as an argument. This is because Type 1 and CID font records in FreeType have this in different places. * src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to `FT_Face' so that CID is also accepted. Take `PS_Private' as an argument and let caller figure out where the Private dict actually is. Update references. * include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update declaration. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update call.

2017-09-25T06:54:16

Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags.

2017-09-25T06:49:41

Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call.

Reorganize object fields. Make some fields more generic, so that we can access them the same way regardless of Type 1 or CFF. * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' to `FT_Face'. Remove unused fields. * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. Add some asserts to guard against casting `T1_Face' as `TT_Face'. * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow `CFF_GlyphSlot', so that we can pretend they are the same in the interpreter. * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): Updated with above changes.
