2bfdc161	2021-05-29T00:27:40	[build] Allow overriding of `ANSIFLAGS` for GNU make build. * builds/*: Implement it.
28eee363	2021-05-27T11:38:56	[type42] Fix auto-hinting. The autohinter could not access the base (unscaled) outline in the child TrueType glyph slot. We now share the internal parts between the parent and child glyph slots. Fixes #1057. * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts of `T42_GlyphSlot' and replace it with the child TrueType structure. (T42_GlyphSlot_Done): Updated accordingly.
0d1c306e	2021-05-25T11:27:56	[psaux] Guard and trace AFM kern data allocation. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=31543 * include/freetype/internal/fttrace.h: Add 'afmparse' trace component. * src/psaux/afmparse.c (FT_COMPONENT): Define. (afm_parse_track_kern, afm_parse_kern_pairs): Protect against allocations bombs. Add tracing. (afm_parse_kern_data): Don't allow multiple kern data sections.
16947c0e	2021-05-23T05:36:16	* meson.build (ft2_public_headers): Add missing `ftcid.h'. Fixes #1058.
2468e59a	2021-05-20T22:20:36	[type42] Avoid some memory zeroing. * src/type42/t42objs.c (T42_Open_Face): Tweak allocation macro. * src/type42/t42parse.c (t42_parse_sfnts): Ditto.
ebf9e5ac	2021-05-15T22:36:00	[CMake] Update dependency finders. 1. Fixes CMake using any found HarfBuzz version lower than the minimum required. This is based on HALX99's merge request at https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests/31 2. Update FindHarfBuzz.cmake from https://github.com/WebKit/WebKit/blob/1ce32454/Source/cmake/FindHarfBuzz.cmake and guard post-CMake-3.1 features to keep the minimum version unchanged 3. Update FindBrotliDec.cmake to stop the warnings, based on what https://github.com/google/woff2/blob/a0d0ed7d/cmake/FindBrotliDec.cmake is doing * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Implement 1 and 2. * builds/cmake/FindBrotliDec.cmake: Implement 3.
06e21ffe	2021-05-18T14:49:50	[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`. While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_`) instead of `voidpf` (`void`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`.
81852fbc	2021-05-18T22:18:17	Prioritize the anti-aliasing renderer module. * modules.cfg: Reorder the renderers. * include/freetype/config/ftmodule.h: Ditto.
1bc801b0	2021-05-16T23:12:01	[sfnt] Additional guards on the POST table. Fixes timeout (#1055) analyzed by Ben Wagner, reported as https://crbug.com/1194092 * src/sfnt/ttload.c (tt_face_load_post): Check POST format. * src/sfnt/sfobjs.c (sfnt_load_face): Synthesize the missing unicode charmap only if the glyph names exist. * src/psnames/psmodule.c (ps_unicode_value): Short cut ".notdef" and ".null".
de151657	2021-05-13T23:08:31	[psaux] Use doubling allocation strategy for CF2_ArrStack. Fixes timeout reported as https://crbug.com/1206181 * src/psaux/psarrst.c (cf2_arrstack_{push,init}): Implement it. * src/psaux/psarrst.h (CF2_ArrStackiRec): Drop `chunk'.
2d3f5dd2	2021-05-12T17:24:35	* src/smooth/ftgrays.c (FT_MAX_GRAY_SPANS): Increase from 10 to 16. Ten was barely enough for two slanted stems. Sixteen can actually fit a bit more complicated scanlines.
c653b8d2	2021-05-12T16:17:21	* src/smooth/ftgrays.c (FT_GRAY_SET): Adjust for better code.
8f43d324	2021-05-12T00:04:59	[smooth] Faster bitmap sweeping. Selecting the fill rule or checking the direct mode each time we call `gray_hline' is sub-optimal. This effectively splits the direct mode into a separate code path while inlining `gray_hline' and saving 5-7% of rendering time. * src/smooth/ftgrays.c (gray_hline): Eliminated in favor of... (FT_FILL_RULE, FT_GRAY_SET): ... these new macros... (gray_sweep): ... inlined here. (gray_sweep_direct): New function that handles the direct span buffer. (gray_TWorker): Remove the span buffer. (gray_raster_render, gray_convert_glyph): Updated.
b0702645	2021-05-10T22:06:01	* src/smooth/ftgrays.c (gray_hline): Simplify even-odd computations. It is too bad the even-odd rule is not used much.
967a34ee	2021-05-07T19:17:48	[type1] Avoid MM memory zeroing. * src/type1/t1load.c (t1_allocate_blend, parse_blend_design_map): Tweak allocation macros. * src/type1/t1objs.c (T1_Face_Done): Minor.

82fd32d6	2021-05-03T13:49:14	* src/cid/cidload.c (cid_hex_to_binary): Improve return value. Add argument to return the actual number of bytes that were decoded. The actual number of bytes decoded can be quite variable depending on the number of ignored 'whitespace' bytes or early termination with `>`. (cid_face_open): Updated to use this calculated value. This avoids trusting `parser->binary_length` is always be correct and reading uninitialized bits if fewer are actually decoded. First reported as https://crbug.com/1203240
66630d88	2021-05-03T22:40:16	[sfnt] Streamline POST format 2.0 handing. To reduce memory allocations, we read an entire Pascal-string buffer and convert it to a C-string buffer. We also reject tables with Postscript glyph names exceeding 63 bytes. * src/sfnt/ttpost.c (load_format20): Implement it. (load_post_names): Check the minimal POST table size. (load_format25, tt_face_free_ps_names): Updated accordingly.

f9350be1	2021-04-01T09:44:00	[base] Complete `ft_glyphslot_clear`. * src/base/ftobjs.c (ft_glyphslot_clear): This function is intended to reset all the values of a glyph slot. However, it was not resetting the values of the advances and `glyph_index`. Reset the advances and `glyph_index` to zero.
369d8be9	2021-03-31T22:31:44	[truetype] Prevent glyph program state from persisting. `FDEF` instructions are specified as allowed only in 'prep' or 'fpgm'. FreeType has attempted to prevent their use in the glyph program, but they were still allowed in glyph programs if defined in a function defined in 'prep' or 'fpgm' and called from the glyph program. Similarly, `IDEF` instructions are specified not to be able to modify any existing instruction. FreeType has attempted to prevent their use in the glyph program, but they can still be used like `FDEF`. This change stores the initial bytecode range type and disallows the use of `FDEF` and `IDEF` while running the glyph program. Most other state is copied from the `TT_Size` into the execution context. However, it is possible for a glyph program to use `WS` to write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to write to the control value table. Allowing any change to the global state from the glyph program is problematic as the outlines of any given glyph may change based on the order the glyphs are loaded or even how many times they are loaded. There exist fonts that write to the storage area or the control value table in the glyph program, so their use should not be an error. Possible solutions to using these in the glyph program are * ignore the writes; * value-level copy on write, discard modified values when finished; * array-level copy on write, discard the copy when finished; * array-level copy up-front. Ignoring the writes may break otherwise good uses. A full copy up-front was implemented, but was quite heavy as even well behaved fonts required a full copy and the memory management that goes along with it. Value-level copy on write could use less memory but requires a great deal more record keeping and complexity. This change implements array-level copy on write. If any attempt is made to write to the control value table or the storage area when the initial bytecode range was in a glyph program, the relevant array will be copied to a designated storage area and the copy used for the rest of the glyph program's execution. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, `glyfStorage`, and `origStorage`. * src/truetype/ttinterp.c (Modify_CVT_Check): New function to handle `exc->glyfCvt`. (Write_CVT, Write_CVT_Stretched, Move_CVT, Move_CVT_Stretched): Use it. (Ins_WS): Handle `exc->glyfStorage`. (Ins_FDEF, Ins_IDEF): Updated. (TT_RunIns): Updated.

Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1182552 Memory is allocated and the pointer assigned to `rows` inside a 'setjmp' scope. This memory must be freed outside the 'setjmp' scope after a 'longjmp'. Since `rows` is a local and modified inside the 'setjmp' scope it must be marked volatile or it will have an indeterminate value after the 'longjmp'. * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak of `rows`.

7227aabb	2021-03-04T06:41:30	Revert "[sfnt] Fix crash in `Load_SBit_Png` on Windows x64." This reverts commit dbf9142f7e0432c9ed618b3276e2b61fa39e7262, as discussed in #1037.
dbf9142f	2021-02-25T15:07:25	[sfnt] Fix crash in `Load_SBit_Png` on Windows x64. This change fixes a crash that occurs in `Load_SBit_Png` when running on a 64-bit Windows OS. A memory access violation exception would be raised by `setjmp` if the `jmp_buf` is not aligned to a 16-byte memory boundary. This is due to setjmp executing `movdqa` instructions to store 128-bit XMM registers to memory, which require correct memory alignment. This problem occurs because `png_create_read_struct` uses `malloc` and `free` for memory management, which only guarantees 8-byte alignment on Windows. Instead, to fix the problem, `png_create_read_struct_2` is used on 64-bit Windows, which allows for user-defined memory allocation and deallocation callbacks to be specified. These callbacks forward the allocation and deallocation requests to `_aligned_alloc` and `_aligned_free`, ensuring that the allocated `png_struct` and internal `jmp_buf` have the requisite 16-byte alignment. * src/sfnt/pngshim.c <_WIN64>: Include `malloc.h`. (malloc_callback, free_callback) <_WIN64>: New functions. (Load_SBit_Png) <_WIN64>: Use `png_create_read_struct_2` instead of `png_create_read_struct`
e1f364e5	2021-02-25T20:00:07	[woff2] Fix memory leak. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=28148 * src/sfnt/sfwoff2.c (woff2_open_font): Reject fonts that have multiple tables with the same tag. While not explicitly forbidden in the OpenType specification, it is implicitly forbidden by describing a binary search algorithm for tables that only works reliably if table tags are unique.
df7fcafe	2021-02-22T15:33:23	* CMakeLists.txt: Update location of `LICENSE.TXT`. Fixes #1035.
111f2f27	2021-02-19T20:33:50	* builds/unix/ax_pthread.m4: Update from 'autoconf-archive'. A bunch of fixes were added recently to its git repository.
eca35e04	2021-02-17T21:10:34	[unix] Updates for autoconf 2.71. This fixes warnings reported by autoupdate. * builds/unix/ax_pthread.m4: Replace `as_echo` with `AS_ECHO`. * builds/unix/configure.raw: Remove obsolete `AC_HEADER_STDC`. Don't escape back quotes in messages for `AC_MSG_WARN`.
635d394f	2021-02-16T19:24:15	* builds/toplevel.mk: Fix previous commit. <top_level>: Use `TOP_DIR` in `wildcard` function. (check_out_submodule, copy_submodule): Move down to come after definition of `all` rule. Call `mkdir` conditionally.
c3a0b43e	2021-02-16T17:04:51	* builds/toplevel.mk: Use rules for handling 'dlg'. Suggested by Alexei. (check_out_submodule, copy_submodule): New targets. <top-level>: Replace calls to `shell` with rules.
dfa7cca5	2021-02-16T14:29:45	* builds/toplevel.mk: Avoid side effects of `shell`. We use a dummy variable to catch its output. Otherwise the `make` program is going to interpret the return value of `shell`; this can cause obscure warning or error messages or even be harmful.
92bd99bd	2021-02-16T14:07:18	Move 'dlg' submodule to `subprojects` directory. This is for future changes with Meson, which doesn't allow a different name for its `subprojects` directory. Having both a `submodules` and a `subprojects` directory is confusing. * .gitmodules, autogen.sh (copy_submodule_files, DLG_INC_DIR, DLG_SRC_DIR): Updated. * builds/toplevel.mk (<top-level>, do-dist), builds/windows/vc2010/script.bat: Updated. * src/tools/no-copyright: Updated.
215ae253	2021-02-16T12:53:45	[sfnt] Update paint format values to support non-variable paints. * freetype.h (FT_PaintFormat): Update paint format identifiers after a specification change. The specification was updated to have sibling formats, variable and non-variable variants for each. Reflect that here. * sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as the non-variable formats no longer have them.
b2aeca5f	2021-02-14T20:25:21	* CMakeLists.txt: Improve 'bz2' support. Not all distributions such as FreeBSD provide a `.pc` file for '(lib)bz2' so follow autotools and add it to `Libs.private` instead.
7849316c	2021-02-13T09:21:37	* src/tools/update-copyright-year: Fix single-year entry handling. The fix from 2021-01-17 didn't cover the case where the year to be updated is identical to the current year.
d51452e3	2021-02-13T08:52:58	Add new function `FT_Get_Transform`. See https://github.com/harfbuzz/harfbuzz/issues/2428 for some reasons to introduce this function. * include/freetype/freetype.h, src/base/ftobjs.c (FT_Get_Transform): Implement it.

Fixes #1026 when compiling FreeType with an unusual calling convention while the C library qsort still expects cdecl.
54c5ad5c	2021-02-10T19:24:13	[sfnt] Implement 'COLR' v1 sweep gradients. * freetype.h (FT_PaintSweepGradient): Add `FT_PaintSweepGradient` to represent a 'COLR' v1 sweep gradient. Update format. (FT_PaintFormat): Update shifted paint formats. Sync with spec. * sfnt/ttcolr.c (read_paint): Logic to parse sweep gradients. Fix struct access in radial gradient implementation.
64f01bfe	2021-01-20T13:04:50	[sfnt] Provide optional root transform for 'COLR' v1 glyph graph. * include/freetype/freetype.h (FT_Get_Color_Glyph_Paint): Additional function argument root_transform to control whether root transform should be returned. (FT_OpaquePaint): Additional tracking field to denote whether root transform is to be returned. * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_Paint_Func): Propagate additional argument. * src/base/ftobjs.c (FT_Get_Color_Glyph_Paint): Ditto. * src/sfnt/ttcolr.c (tt_face_get_colr_glyph_paint): Return root transform reflecting the size and tranform configured on FT_Face. (read_paint): Initialize and track status of insert_root_transform flag.
cc90307d	2021-02-10T09:30:40	* meson.build: s/freetype2_dep/freetype_dep/. Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep` variable name to use FreeType as subproject because that was the variable name in Centricular's Meson port of FreeType. While they should stop hardcoding that variable name, it does not cost us anything to keep using that name to ease transition.
3dbdb78a	2021-02-10T09:25:42	[meson] Fix handling of HarfBuzz library. * meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by default. Otherwise it causes a dependency cycle: cairo => fontconfig => freetype2 => harfbuzz => cairo Meson will still fall back to HarfBuzz subprojects if the `harfbuzz` option is set to `enabled` instead of `auto` and a `subprojects/harfbuzz.wrap` file is present. In that case it is the responsibility of the main project to set the proper options on each subproject to break the dependency cycle. Fixes: #1028.
2c405596	2020-10-26T14:56:05	Meson: Fix dependency lookup and generate ftconfig.h [meson] Fix dependency lookup and generate `ftconfig.h`. - zlib: If not found on the system, meson can build it as a subproject. We thus never use the (outdated) zlib support that comes with FreeType. Doing so has the additional advantage that the zlib code can be shared with other projects like GLib if both are subprojects of an application. - harfbuzz: Build as a subproject if not found on the system. - 'QUESTION: What if the compiler doesn't support `-D` but uses `/D` instead as on Windows?' Answer: Meson translate arguments for us. - visibility: Replace self-made code with meson-specific solution. * meson.build (ft2_defines): Rewrite logic to set and handle it. (process_header_command): New variable, previously called `ftoption_command`. (ftoption_command, ftconfig_command): New variables. (zlib_option): Removed. (zlib_dep): New variable. (ft2_deps): Updated. (harfbuzz_dep): Updated. (ftconfig_h_in, ftconfig_h): New variables. (ft2_sources): Updated. (ft2_lib): Updated, handle visibility. (summary): Updted. * meson_options.txt (zlib): Updated.
e11cc40a	2020-10-26T14:21:19	* meson.build: Fix resource compilation on Windows. This is copied from GStreamer's meson port of FreeType. (ft2_sources): Add both debug and resource file (the latter for Windows only). (ft2_debug_src): Removed.
69e0faa8	2020-10-26T13:39:19	* meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/. (freetype2_dep): Use it. `ft2_libtool_version` would be the shared library version, not the one we should use in file `freetype2.pc`.

[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`. While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`.

[truetype] Prevent glyph program state from persisting. `FDEF` instructions are specified as allowed only in 'prep' or 'fpgm'. FreeType has attempted to prevent their use in the glyph program, but they were still allowed in glyph programs if defined in a function defined in 'prep' or 'fpgm' and called from the glyph program. Similarly, `IDEF` instructions are specified not to be able to modify any existing instruction. FreeType has attempted to prevent their use in the glyph program, but they can still be used like `FDEF`. This change stores the initial bytecode range type and disallows the use of `FDEF` and `IDEF` while running the glyph program. Most other state is copied from the `TT_Size` into the execution context. However, it is possible for a glyph program to use `WS` to write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to write to the control value table. Allowing any change to the global state from the glyph program is problematic as the outlines of any given glyph may change based on the order the glyphs are loaded or even how many times they are loaded. There exist fonts that write to the storage area or the control value table in the glyph program, so their use should not be an error. Possible solutions to using these in the glyph program are * ignore the writes; * value-level copy on write, discard modified values when finished; * array-level copy on write, discard the copy when finished; * array-level copy up-front. Ignoring the writes may break otherwise good uses. A full copy up-front was implemented, but was quite heavy as even well behaved fonts required a full copy and the memory management that goes along with it. Value-level copy on write could use less memory but requires a great deal more record keeping and complexity. This change implements array-level copy on write. If any attempt is made to write to the control value table or the storage area when the initial bytecode range was in a glyph program, the relevant array will be copied to a designated storage area and the copy used for the rest of the glyph program's execution. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `iniRange`, `glyfCvtSize`, `glyfCvt`, `origCvt`, `glyfStoreSize`, `glyfStorage`, and `origStorage`. * src/truetype/ttinterp.c (Modify_CVT_Check): New function to handle `exc->glyfCvt`.

dbf9142f

2021-02-25T15:07:25

[sfnt] Fix crash in `Load_SBit_Png` on Windows x64. This change fixes a crash that occurs in `Load_SBit_Png` when running on a 64-bit Windows OS. A memory access violation exception would be raised by `setjmp` if the `jmp_buf` is not aligned to a 16-byte memory boundary. This is due to setjmp executing `movdqa` instructions to store 128-bit XMM registers to memory, which require correct memory alignment. This problem occurs because `png_create_read_struct` uses `malloc` and `free` for memory management, which only guarantees 8-byte alignment on Windows. Instead, to fix the problem, `png_create_read_struct_2` is used on 64-bit Windows, which allows for user-defined memory allocation and deallocation callbacks to be specified. These callbacks forward the allocation and deallocation requests to `_aligned_alloc` and `_aligned_free`, ensuring that the allocated `png_struct` and internal `jmp_buf` have the requisite 16-byte alignment. * src/sfnt/pngshim.c <_WIN64>: Include `malloc.h`. (malloc_callback, free_callback) <_WIN64>: New functions. (Load_SBit_Png) <_WIN64>: Use `png_create_read_struct_2` instead of `png_create_read_struct`

Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep` variable name to use FreeType as subproject because that was the variable name in Centricular's Meson port of FreeType. While they should stop hardcoding that variable name, it does not cost us anything to keep using that name to ease transition.
