2d957848 2021-05-06 22:49:13 * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Tweak allocation.
8150ed0d 2021-05-05 23:30:46 [cff,psaux] Avoid memory zeroing (contd.). * src/cff/cffload.c (cff_blend_doBlend, cff_blend_build_vector): Tweak allocation macros. * src/psaux/psarrst.c (cf2_arrstack_setNumElements): Ditto. * src/psaux/psstack.c (cf2_stack_init): Ditto.
82fd32d6 2021-05-03 13:49:14 * 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

f9350be1 2021-04-01 09:44:00 [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.
52f2a008 2021-04-01 09:33:47 Update TT_New_Context documentation In commit 531d463aed365b [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. the `TT_ExecContext` was moved from being on the driver to being on the size to make it easier to use FreeType in a multi-threaded environment. However, the documentation for `TT_New_Context` was not updated and still reflects the old behavior and parameter list. This change updates `TT_New_Context` documentation to reflect the current parameters and usage.
369d8be9 2021-03-31 22:31:44 [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. (TT_Done_Context): Free 'glyf' CVT working and storage area. (TT_Load_Context): Fix/add casts. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Fix cast.
1c086293 2021-04-02 06:55:29 [sfnt] Check validity of pointer location of `read_color_line`. * src/sfnt/ttcolr.c (get_child_table_pointer): New function to fetch child table pointer early for all paint formats that compute a child table pointer. (read_color_line, read_paint): Updated. (tt_face_get_colorline_stops): Check `colr->table`.
e9c50fa7 2021-03-16 22:12:41 * src/sfnt/pngshim.c (Load_SBit_Png): Free `rows` once later.
b0729b8f 2021-03-15 14:32:24 [sfnt] Fix memory leak in png loading. 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`.
fb9bf2ef 2021-03-15 22:33:17 * src/smooth/ftgrays.c (gray_set_cell): Refactor to fix VC++ warning.

Fixes #1039. * src/base/ftstroke.c (ft_stroker_inside, ft_stroker_outside): Initialize `sigma`. * src/sdf/ftsdf.c (sdf_generate_with_overlaps): Exit immediately if function arguments are invalid. * src/sdf/ftsdfrend.c (sdf_property_set) <"overlaps">: Fix cast. * src/sfnt/sfwoff2.c (woff2_decompress) [!FT_CONFIG_OPTION_USE_BROTLI]: Use `FT_UNUSED`. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Initialize `fvar_head`.
80bda804 2021-03-11 22:40:19 [smooth] Reduce copying during integration phase. We now record `cover' and `area' directly into the linked list. This makes rendering faster by 10% or even more at larger sizes. * src/smooth/ftgrays.c (FT_INTEGRATE): Write directly. (gray_TWorker): Add direct cell reference and remove unused fields. (gray_set_cell): Consolidate the linked list management and pointers. (gray_convert_glyph, gray_convert_glyph_inner): Updated.
d5b7de55 2021-03-11 22:08:45 * src/smooth/ftgrays.c (FT_INTEGRATE): New convenience macro. (gray_render_line, gray_render_scanline): Use it.
85168499 2021-03-09 22:14:44 * src/smooth/ftgrays.c (gray_render_line): Rearrange conditionals. These produce faster or more optimizable code.
7227aabb 2021-03-04 06:41:30 Revert "[sfnt] Fix crash in `Load_SBit_Png` on Windows x64." This reverts commit dbf9142f7e0432c9ed618b3276e2b61fa39e7262, as discussed in #1037.
dbf9142f 2021-02-25 15:07:25 [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 2021-02-25 20:00:07 [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.
92bd99bd 2021-02-16 14:07:18 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 2021-02-16 12:53:45 [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.
7849316c 2021-02-13 09:21:37 * 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.

d924a66a 2021-02-04 07:44:06 * 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.
0636dc8a 2021-02-03 19:16:02 [psaux] Fix integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=30154 * src/psaux/psblues.c (cf2_blues_capture): Use `SUB_INT32`.
324612ce 2021-01-31 14:28:44 Always provide logging API. It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to modify `ftexport.sym` conditionally. Problem reported by Alexei. * src/base/ftdebug.c: Include `ftlogging.h`. (FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler, FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.
