Werner Lemberg 7af8fd00 2023-04-27T07:37:14 * include/freetype/internal/services/svmm.h: Minor changes.
Werner Lemberg 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.
Werner Lemberg fb982e78 2023-04-26T08:17:17 New Variation Font function `FT_Get_Default_Named_Instance`. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Get_Default_Named_Instance): New function. * include/freetype/internal/services/svmm.h (FT_Get_Default_Named_Instance_Func): New typedef. (FT_Service_MultiMasters): New field `get_default_named_instance`.

Alexei Podtelezhnikov f2f97545 2023-05-03T23:02:04 [cache] Revise list cleansing. * src/cache/ftcmru.c (FTC_MruList_RemoveSelection): Use one loop to do it. * src/cache/ftcmanag.c (FTC_Manager_Compress, FTC_Manager_FlushN): Streamline loops.
suzuki toshiya be15811c 2023-05-03T01:31:37 [t1cid] Improve cid_get_cid_from_glyph_index(). Update cid_get_cid_from_glyph_index() to return an error and CID=0 in the case that the specified glyph index points to an invalid entry. cidgload.h (cid_compute_fd_and_offsets): Declare new helper function to set the fd_select and 2 offsets to access the glyph description data. cidgload.c (cid_compute_fd_and_offsets): Move the part loading fd_select and 2 offsets from cid_load_glyph() to here. If the loaded parameters are broken, return the Invalid_Offset error. This function does not load the glyph data, only fills these parameters. (cid_load_glyph): Use new helper function in above. cidriver.c (cid_get_cid_from_glyph_index): Check whether the requested glyph index points to a valid entry, by calling cid_compute_fd_and_offsets(). If it is valid, fill the cid by the glyph index (=CID). If it is invalid, return an error and fill the cid by 0.
Werner Lemberg 77bbfc59 2023-04-24T09:48:09 API documentation: Re-organize chapters and sections * Split the very long 'Base Interface' section into smaller sections. * Split the 'Core API' chapter into two chapters. * Remove single enumeration values from `@order` fields since they have no effect.
Alexei Podtelezhnikov 36a086b6 2023-04-28T19:40:35 * src/sfnt/pngshim.c (Load_SBit_Png): Remove FALL_THROUGH warning.
Werner Lemberg 08268691 2023-04-28T15:32:16 * src/sfnt/ttload.c (tt_face_load_font_dir): Add another guard. Reject 'OTTO' fonts with no valid tables.
Werner Lemberg 966ff5a5 2023-04-28T15:25:20 * src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash. The situation can happen if `FT_New_Face` (or one of its siblings) is called with a negative index to get the number of contained faces, followed immediately by a call to `FT_Get_Postscript_Name`. While this is not a valid use of the FreeType library there is no need for a crash. Fixes #1219.
Werner Lemberg 17a0c5df 2023-04-28T10:40:41 * src/cff/cffdrivr.c (cff_ps_get_font_info): Reject 'CFF2' format.
Werner Lemberg 4908c1e8 2023-04-28T06:54:25 * src/cid/cidgload.c (cid_load_glyph): Fix compiler warnings.

Werner Lemberg 40676afc 2023-04-25T09:30:30 [sfnt] Fix handling of PS names for Variation Fonts. * src/sfnt/sfdriver.c (get_win_string, get_apple_string): Continue construction of string if an invalid character is encountered. Fixes #1218.
suzuki toshiya f312b340 2023-04-22T02:11:21 [t1cid] Change the trace messages of the charstrings retrieval errors. The t1cid driver catches 3 types of errors in the charstrings retrieval; A) The invalid FD number, there are 2 subtypes; A-1) FD number is the maximum number fitting to FDBytes. A-2) FD number is greater than num_dicts. B) Declared length is overrunning. C) Declared length is invalid (its end is before its head). Considering that some widely distributed fonts (e.g., "CJKV" book by O'Reilly) have A-1 errors in the unimplemented glyphs, the trace level for A-1 is calmed to level 1. The errors A-2, B, and C would be irregular; their trace levels are kept at level 0, but the updated trace messages include the CID number.
suzuki toshiya 9806414c 2023-04-24T13:36:30 [truetype] Fix `make multi'. * src/truetype/ttgxvar.c: Include freetype/internal/services/svmetric.h for the FT_Service_MetricsVariations type definition.
Ben Wagner 8154d8e2 2023-04-19T13:48:59 [services] FT_Size_Reset_Func to return FT_Error The `MetricsVariations` `FT_Size_Reset_Func` is currently defined to return `void`, but the implementations return `FT_Error`. Even though the pointers passed will be the same at runtime, calling a function through a pointer of a different type from the original function pointer type is undefined behavior. This may be caught at runtime by Control Flow Integrity with something like clang's `cfi-icall`. Issue: https://crbug.com/1433651 * include/freetype/internal/services/svmetric.h (FT_Size_Reset_Func): return `FT_Error` instead of `void`.
Ben Wagner c4fe77c3 2023-04-17T11:17:16 [truetype] tt_size_reset_height to take FT_Size The `MetricsVariations` `FT_Size_Reset_Func` is defined to take an `FT_Size`. Because `tt_size_reset_height` is to be used as such a function, it must also take an `FT_Size` instead of a `TT_Size`. Even though the pointers passed will be the same at runtime, calling a function through a pointer of a different type from the original function pointer type is undefined behavior. This may be caught at runtime by Control Flow Integrity with something like clang's `cfi-icall`. Issue: https://crbug.com/1433651 * src/truetype/ttobjs.h (tt_size_reset_height): take `FT_Size` * src/truetype/ttobjs.c (tt_size_reset_height): take `FT_Size` and update documentation
Werner Lemberg ea9fca0a 2023-04-13T06:34:32 * src/truetype/ttinterp.c: Remove outdated comments.
Ben Wagner e78e2d29 2023-04-06T11:16:29 [sfnt, truetype] Add `size_reset` to `MetricsVariations`. This is a generalization of commit ``` commit e6699596af5c5d6f0ae0ea06e19df87dce088df8 Author: Werner Lemberg <wl@gnu.org> Date: Thu Feb 2 11:38:04 2017 +0100 [truetype] Fix MVAR post-action handling. ``` It is also possible for plain `CFF ` style fonts to contain an `fvar` and `MVAR` table and use `cff_metrics_adjust`. `tt_size_reset` should only be called with `TT_Size` and never with `CFF_Size`. Allow the "metrics-variations" service to specify the correct function (if any) to reset `FT_Size`s after adjusting metrics. * src/truetype/ttobjs.c (tt_size_reset): Split off some functionality into... (tt_size_reset_height): ... this new function. * src/truetype/ttdriver.c (tt_service_metrics_variations): Add `size_reset`. (tt_size_select, tt_size_request): Updated. * src/truetype/ttobjs.h: Updated. * include/freetype/internal/services/svmetric.h (MetricsVariations): Add `size_reset`. (FT_DEFINE_SERVICE_METRICSVARIATIONSREC): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec_): Rename `var` to `tt_var` and add `face_var`. * src/cff/cffdrivr.c (cff_service_metrics_variations): Add `size_reset`. (cff_hadvance_adjust, cff_metrics_adjust): Updated. * src/cff/cffobjs.c (cff_face_init): Use `face_var`. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `face_var`. * src/sfnt/ttmtx.c (tt_face_get_metrics): Use `tt_var`. * src/truetype/ttgxvar.c (tt_size_reset_iterator): Renamed to... (ft_size_reset_iterator): ... this new function. Call `size_reset`. (tt_apply_mvar): Pass `size_reset` to `ft_size_reset_iterator`. Fixes #1211
Alexei Podtelezhnikov e77d8ba8 2023-04-10T15:17:17 * src/cff/cffcmap.c (cff_cmap_encoding_char_next): Abbreviate.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov d2544433 2023-04-08T23:15:41 [sfnt] Clean up CMAP{4,12,13} handling. This moves the charcode overflow checks upstream and turns some while-loops into the do-while ones to avoid the uninitialized warnings. This should slightly reduce the number of checks and jumps. * src/sfnt/ttcmap.c (tt_cmap{4,12,13}_next, tt_cmap{4.12.13}_char_map_linear): Remove the charcode overflow check. (tt_cmap{4,12,13}_char_map_binary): Ditto and use do-while. (tt_cmap{12,13}_char_next): Add the overflow check.
Alexei Podtelezhnikov b0a4f992 2023-04-02T22:45:48 * src/sfnt/ttpost.c (load_format_25): Do not abort frame reading.
Alexei Podtelezhnikov 340767bf 2023-04-02T22:00:59 * src/sfnt/ttpost.c (load_format_*): Streamline frame reading.
Alexei Podtelezhnikov 311b78fa 2023-04-02T09:24:16 * src/sfnt/ttpost.c: Formatting and comments.
Alexei Podtelezhnikov 8f7b1455 2023-04-01T23:37:51 [sfnt] Consolidate POST version 2.0 and 2.5 (pt 2). * src/sfnt/ttpost.c (load_format_20, load_format_25): Update arguments and move shared calls and checks upstream to... (load_post_names): ... this function. (tt_face_free_ps_names, tt_face_get_ps_name): Updated.
Alexei Podtelezhnikov 9597a62b 2023-04-01T22:34:30 [sfnt] Consolidate POST version 2.0 and 2.5 (pt 1). The deprecated POST version 2.5 can be handled using the data structures of version 2.0. The goal is to reduce the footprint. * include/freetype/internal/tttypes.h (TT_Post_Names): Absorb and... (TT_Post_20, TT_Post_25): ... remove these structures. src/sfnt/ttpost.c (load_post_names, tt_face_get_ps_name, tt_face_free_ps_names, load_format_20): Updated accordingly. (load_format_25): ditto and convert offsets to glyph indices.
Alexei Podtelezhnikov 6d7b8b22 2023-03-31T23:17:46 [sfnt] Miscellaneous POST clean-ups. * src/sfnt/ttpost.c (load_format_20): Decrease casts. (load_format_25): Check the table length and impose a theoretical glyph number limit usable with 8-bit offset. Decrease casts. (load_post_names): Pass the mapping data length without 2 bytes.
Alexei Podtelezhnikov 0db69970 2023-03-30T09:06:35 * src/sfnt/ttpost.c (load_format_20): Simplify comutations.
Alexei Podtelezhnikov 4679fcb6 2023-03-29T00:21:00 [sfnt] Streamline POST format 2.0 handing (cont'd). * src/sfnt/ttpost.c (load_format_20): Co-allocate the string data and their pointers, which makes it easier to handle and free them. (tt_face_free_ps_names): Updated. * include/freetype/internal/tttypes.h (TT_Post_20): Update type.
Alexei Podtelezhnikov 4d8db130 2023-03-20T16:53:51 [cff] Simplify `t2_strings` management in the old engine. * src/cff/cffparse.c (cff_parser_run): Allocate the charstring buffers and the list nodes together so that they can be freed at once. (finalize_t2_strings): Removed as no longer needed. (cff_parser_done): Updated.
Alexei Podtelezhnikov 4f0a55d1 2023-03-19T10:13:52 [cff] Rework the stream limit checks. The old stream limit checks, before 6986ddac1ece, were good but pointless for the crafted t2_strings. Checking limits there is not necessary as they are created to hold all data. By using two conditions, we can detect the actual crossing of the stream boundary as appropriate for the stream pointer only. The t2_strings parsing will not be triggering these checks. * src/cff/cffparse.c (cff_parser_within_limits): Removed. (cff_parse_real, cff_parse_integer): Redesign the stream limit check. (cff_parse_num, do fixed, cff_parse_fixed_dynamic): Update callers.
Alexei Podtelezhnikov 8fc6df10 2023-03-17T23:35:10 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use for-loop. Even though we never call `TT_Load_Simple_Glyph` with zero contours, out of abundance of precaution, let's handle this case properly.
Alexei Podtelezhnikov ef636696 2023-03-17T23:25:45 [truetype] Clean up zeroing and local variables. * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Avoid zeroing. (load_truetype_glyph): Avoid zeroing and clean local variables.
Werner Lemberg 7be364c6 2023-03-16T05:25:36 * include/freetype/ftsystem.h (FT_Stream_IoFunc): Improve documentation. Fixes #1208.
Alexei Podtelezhnikov dd78d4a7 2023-03-16T03:28:59 * src/base/ftsynth.c (FT_GlyphSlot_AdjustWeight): New API.
Alexei Podtelezhnikov 764bc8e4 2023-03-15T23:18:18 [truetype] Clean up glyph loading. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Clean space checking. (TT_Hint_Glyph): Don't copy the outline structure. (TT_Process_Simple_Glyph): Cosmetic update.
Alexei Podtelezhnikov e7164762 2023-03-15T18:48:27 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Clean up.
Werner Lemberg d857bd53 2023-03-13T11:47:38 builds/vms/apinames_vms.bash: Fix `unzip` artifact The problem occured when unpacking a zip file created on OpenVMS on Linux. While OpenVMS knows many different file formats, Unix only knows stream-LF and binary. In principle `zip` on Linux should have translated the file to stream-LF but failed to do so. That caused the file to incorrectly contain only one line with control-characters.
Alexei Podtelezhnikov b9376065 2023-03-10T23:41:39 [truetype] Fix recent fallout in memory management. * src/truetype/ttgload.c (TT_Process_Composite_Glyph, TT_Load_Simple_Glyph): Clean up old instructions regardless of new ones, postpone setting `control_len` and `control_data` until... (TT_Load_Glyph): ... the exit from this function.
Jouk Jansen 24d2523c 2023-03-10T16:50:20 Update VMS installation support.
Alexei Podtelezhnikov 49c74ac0 2023-03-09T22:37:03 * src/truetype/ttgload.c (TT_Hint_Glyph): Mostly cosmetic update. The number of instructions is now taken from the executed context. Technically, this means that `control_len` and `control_data` values are no longer _used_ internally but only expose them.
Werner Lemberg bd6208b7 2023-03-08T10:49:42 apinames.c: Add comment.
Werner Lemberg d5c6b948 2023-03-07T08:55:58 [gzip] File `infback.c` is not needed. * src/gzip/infback.c: Remove. * src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.
Werner Lemberg 092f9d98 2023-03-07T07:28:32 [apinames] Fix VMS handling of overly long function names. Based on ideas from Jouk Jansen <joukj@hrem.nano.tudelft.nl>. * src/tools/vms_shorten_symbol.c: New file, taken from https://sourceforge.net/p/vms-ports/vmsshortsym/ci/default/tree/vms_shorten_symbol.c with some minor edits to allow compilation with C++ and being included in another source code file. * src/tools/apinames.c: Include `vms_shorten_symbol.c`. (PROGRAM_VERSION): Set to '0.5'. (names_dump) [OUTPUT_VMS_OPT]: Call `vms_shorten_symbol` to get unique function identifiers not longer than 31 characters.
Werner Lemberg 72a8d652 2023-03-07T07:14:36 * src/tools/apinames.c (panic): Accept variable number of arguments.
Alexei Podtelezhnikov b3250f36 2023-03-06T23:53:42 * src/truetype/ttgload.c (TT_Process_Composite_Glyph): Fix leak too.
Alexei Podtelezhnikov b36193d0 2023-03-06T22:41:17 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Triage memory leak. This leak has been introduced in the previous commit and immediately detected: https://chromium-review.googlesource.com/c/chromium/src/+/4313202
Alexei Podtelezhnikov de94e2cb 2023-02-26T08:07:08 [truetype] Simplify memory management. Instead of using `Update_Max`, switch to regular FreeType memory allocation macros, stop pre-allocating the glyph instruction arrays. * src/truetype/ttgload.c (TT_Load_Simple_Glyph, TT_Process_Composite_Glyph): Switch to regular memory allocation. * src/truetype/ttinterp.c (Update_Max): Removed. (TT_Load_Context): Reallocate stack and free old instructions. (Modify_CVT_Check, Ins_WS): Switch to regular memory allocation. * src/truetype/ttinterp.h (Update_Max): Removed.
David PROVENT b2a94906 2023-03-06T09:22:15 Added information about the zlib version update in the changelog
Alexei Podtelezhnikov fc01e7dd 2023-03-05T22:05:24 Fix a couple of MSVC warnings. * src/base/ftcalc.c (FT_MulAddFix): Add cast. * src/sfnt/ttcolr.c (tt_face_get_colorline_stops, read_paint): Ditto.
Alexei Podtelezhnikov 70946f6d 2023-03-05T16:08:14 * builds/windows/vc2010/freetype.vcxproj: Suppress C4267 on _WIN64. This usually comes from `strlen` returning 64-bit `size_t`, which we often assign to 32-bit `FT_ULong` on Windows-64 (LLP64).
Alexei Podtelezhnikov c4b5127b 2023-03-05T00:31:58 * src/cff/cffparse.c (cff_parser_run): Thinko.

Alexei Podtelezhnikov a2b8937d 2023-03-04T14:00:52 [cff] Clean up memory management in the old engine. * src/cff/cffparse.c (finalize_t2_strings): Fix NULL-dereferencing in the out-of-memory situation, use `FT_FREE`. (cff_parser_run): Use FreeType memory allocation macros and avoid uninitialized pointers.
Alexei Podtelezhnikov 29578f75 2023-03-04T13:39:27 * src/cff/cffobjs.c (cff_size_init): Synonymous change.
Alexei Podtelezhnikov 7ae20e55 2023-03-03T22:41:09 * src/sfnt/sfobjs.c (sfnt_load_face): Shorten de-referencing.
Alexei Podtelezhnikov 49eac0da 2023-03-03T22:10:50 [pfr] Shorten de-referencing. * src/pfr/pfrobjs.c (pfr_face_done, pfr_face_init): Use closer `memory`. * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove `loader`.
Alexei Podtelezhnikov 2adef94f 2023-03-03T18:40:48 * src/cff/cffobjs.c (cff_size_get_globals_funcs): Shorten de-referencing.
Alexei Podtelezhnikov 5ac6276a 2023-03-03T17:21:10 [cff,cid,type1] Shorten de-referencing. * src/cff/cffobjs.c (cff_clot_init): Use immediate library reference. * src/cid/cidobjs.c (cid_slot_init): Ditto. * src/type1/t1objs.c (T1_GlyphSlot_Init): Ditto.
Alexei Podtelezhnikov 5c37b640 2023-03-02T20:53:21 * configure: Use `sed` instead of `grep`. This is more portable and consistent with `autogen.sh`.
Ben Wagner 09b326fa 2023-03-01T12:19:17 Avoid strtol on non-null-terminated data. Technically, `strtol` can only be used with C strings terminated with `\0`. CID data is not generally null-terminated and often does not contain a `\0` if it is hex-encoded. AddressSanitizer with `ASAN_OPTIONS` containing `strict_string_checks=1` verifies this by using an adversarial `strtol` that always reads to the terminating `\0`. To avoid undefined behavior from `strtol` in `cid_parser_new`, use the parser to parse the tokens instead of attempting to parse them ad-hoc. This will internally use `PS_Conv_Strtol` to parse the integer, which respects the parser's limits and directly implements the PostScript parsing rules for integers. * src/cid/cidparse.c (cid_parser_new): Use the parser to parse the tokens. Fixes: https://bugs.chromium.org/p/chromium/issues/detail?id=1420329
Alexei Podtelezhnikov e95e6234 2023-03-02T17:58:03 * src/cff/cffload.c (cff_subfont_load): Synonymous update.
ubawurinna e8931f8c 2023-03-01T18:20:46 * src/gzip/README.freetype: Update version.
ubawurinna 79c8bd91 2023-03-01T10:16:59 [gzip] Fix static linking. Without this patch, static linking with MS Visual Studio causes linking errors. * src/gzip/ftgzip.c: Set `ZEXPORT` to nothing and `ZEXTERN` to static for all compilers.
Werner Lemberg d874ffa9 2023-03-01T06:36:59 * include/freetype/internal/compiler-macros.h (FALL_THROUGH): Update. This follows https://lists.gnu.org/archive/html/bug-gnulib/2023-02/msg00200.html
Alexei Podtelezhnikov 638df2fe 2023-02-27T21:54:23 [truetype] Treat 38 as 40 without Infinality. * include/freetype/ftdriver.h (TT_INTERPRETER_VERSION_38): Reinstate. * src/truetype/ttdriver.c (tt_property_set): Fallback from 38 to 40.
Werner Lemberg 2257f9ab 2023-02-26T20:23:43 * include/freetype/internal/compiler-macros.h (FALL_THROUGH): Update. This follows https://lists.gnu.org/archive/html/bug-gnulib/2023-02/msg00159.html
Werner Lemberg d399657f 2023-02-26T20:18:54 * src/*: Replace leading underscores with trailing ones in dummy variables. This is to avoid clang warnings.
Karl Berry f19ab673 2023-02-26T07:27:31 * configure: Don't hardcode `grep -E`. TeXLive still supports Solaris 5.10, where the system's `grep` doesn't accept the `-E` option. We thus introduce an `EGREP` variable that is set to either `grep -E` or `-egrep`.
Alexei Podtelezhnikov 6423ddb8 2023-02-25T21:54:21 * src/cff/cffload.c (cff_encoding_load): Optimize array zeroing. This is unnecessary for predefined standard and expert encodings. Even for custom encodings the arrays might be already zeroed when CFF_FontRec is created but we keep it just in case.
Alexei Podtelezhnikov 74c498a3 2023-02-25T11:02:21 * src/type1/t1load.c (T1_Get_MM_Var): Optimize array zeroing.
Tamir Duberstein 3f2ac7d8 2023-02-24T11:48:48 * src/base/ftsystem.c (ft_ansi_stream_io): Avoid undefined behaviour. Also short-circuit on `offset` to avoid checking `count` a second time when `ft_ansi_stream_io` is used for reading. Per ISO/IEC 9899: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or apointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined. If a function argument is described as being an array, the pointer actually passed to the function shall have a value such that all address computations and accesses to objects (that would be valid if the pointer did point to the first element of such an array) are in fact valid. Per IEEE Std 1003.1: size_t fread(void *restrict ptr, size_t size, size_t nitems, FILE *restrict stream); The `fread` function shall read into the array pointed to by `ptr` up to `nitems` elements whose size is specified by `size` in bytes, from the stream pointed to by `stream`. Since the first argument to `fread` is described as being an array, its behavior is undefined when that argument is a null pointer. Per the documentation on `ft_ansi_stream_io`: If `count' is zero (this is, the function is used for seeking), a non-zero return value indicates an error. Thus the intent is clear, and the call to `fread` can be skipped, avoiding undefined behaviour.
Alexei Podtelezhnikov 3f01161f 2023-02-21T16:17:07 [raster] Clean up contour indexing. * src/raster/ftraster.c (Decompose_Curve, Convert_Glyph): Use consistent index types (Int) and compact iterations.
Alexei Podtelezhnikov 7f949904 2023-02-20T23:29:58 [autofit] Clean up contour indexing. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Refactor. * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Ditto.
Alexei Podtelezhnikov 78464d1b 2023-02-20T22:31:21 * src/base/ftoutln.c (FT_Outline_Check): Fix C4701 warning.
Alexei Podtelezhnikov f5f969a8 2023-02-20T22:29:18 * src/sdf/ftsdf.c (get_min_distance_cubic): Fix C4701, typos.
Alexei Podtelezhnikov fecd19b4 2023-02-20T17:13:40 * src/base/ftstroke.c (FT_Stroker_ParseOutline): Clean up contour indexing.
Alexei Podtelezhnikov 34ed28d0 2023-02-20T16:33:45 [base] Clean up contour indexing. * src/base/ftoutln.c (FT_Outline_Reverse, FT_Outline_EmboldenXY, FT_Outline_Get_Orientation): Set the first and last indexes together. (FT_Outline_Decompose): Ditto and check them more stringently. * src/smooth/ftgrays.c (FT_Outline_Decompose)[STANDALONE_]: Ditto.
Alexei Podtelezhnikov 713580f4 2023-02-20T15:58:04 * src/base/ftoutln.c (FT_Outline_Check): Update error code, clean up.
Alexei Podtelezhnikov bbfcd79e 2023-02-17T04:22:24 [truetype] Hide Infinality. Remove Infinality as an option before its complete extraction. * include/freetype/ftoption.h: Remove the Infinality option. * devel/ftoption.h: Ditto. * include/freetype/ftdriver.h (TT_INTERPRETER_VERSION_38): Is 40 now.
Alex Ringlein 74ea5454 2023-02-16T22:38:35 * src/base/ftoutln.c (FT_Outline_Reverse): Anchor first contour points. A cubic contour has to always start from an on-point. Therefore, we should not swap the first with the last point, which might be off, and obtain an invalid contour. This does not matter for conic contours. If anything, it also saves one swap there. Fixes #1207.
Werner Lemberg 0eca6ead 2023-02-16T06:35:33 Documentation improvement for `FT_Bitmap`. Fixes #1205.
Alexei Podtelezhnikov dacbb554 2023-02-10T08:24:33 [type1/MM] Round design coordinates. The design coordinates for MM fonts were not rounded. For example, `FT_Get_Var_Design_Coordinates` returned values with fractional part. * src/type1/t1load.c (mm_axis_unmap): Refactor with rounding. * include/freetype/ftmm.h (FT_Var_Axis, FT_Set_Var_Design_Coordinates, FT_Get_Var_Design_Coordinates): Reword documentation.
Jan Alexander Steffens (heftig) 23e60cae 2023-02-09T19:22:47 * builds/meson/parse_modules_cfg.py: Handle `gxvalid` and `otvalid`. These need a name mapping similar to what was done for other modules, or linking will fail.
Werner Lemberg 79a8201e 2023-02-09T07:32:05 * build/toplevel.mk (do_dist): Fix typo.

Werner Lemberg 995ccfac 2023-02-08T21:49:56 [autofit] Fix 'multi' compilation. * src/autofit/ft-hb.c: Decorate with `FT_LOCAL_DEF`. Add ANSI boilerplate code for otherwise empty file. * src/autofit/ft-hb.h: Include `compiler-macros.h` and `freetype.h`. Use `FT_BEGIN_HEADER` and `FT_END_HEADER`. Decorate with `FT_LOCAL`. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `ft-hb.c`.
Werner Lemberg 663486a7 2023-02-08T20:56:19 Fix `FT_LOCAL` and `FT_LOCAL_DEF` tags.
Werner Lemberg 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.
