e9c50fa7	2021-03-16T22:12:41	* src/sfnt/pngshim.c (Load_SBit_Png): Free `rows` once later.
b0729b8f	2021-03-15T14:32:24	[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`.

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.
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.
70fd20e6	2021-02-12T19:28:05	Decorate qsort callbacks with cdecl. * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): Add new macro. * src/base/ftrfork.c, src/bdf/bdflib.c, src/gxvalid/gxvcommn.c, src/psaux/afmparse.c, src/psnames/psmodule.c, src/type1/t1afm.c, src/sfnt/sfwoff.c, src/sfnt/sfwoff2.c: Update qsort callbacks.

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.
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.

97616704	2019-08-14T17:39:55	[woff2] Formatting. * src/sfnt/sfobjs.c, src/sfnt/sfwoff2.c: Better formatting.
2a23dc7f	2019-08-14T02:36:27	[woff2] Support `hmtx' reconstruction when `glyf' is untransformed. `reconstruct_hmtx' requires `info->x_mins' and `info->num_glyphs' to reconstruct the hmtx table. In case glyf is not transformed, we call `get_x_mins' which does the necessary work. * src/sfnt/sfwoff2.c (get_x_mins): New function. (reconstruct_font): Call get_x_mins.
5367e0ca	2019-08-05T01:53:00	[sfnt] Support `face->num_faces' for WOFF2 fonts. Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'. (sfnt_init_face): Introduce variable `woff2_num_faces', and change `face->root.num_faces' if `woff2_num_faces' is set. * src/sfnt/sfwoff2.c (woff2_open_font): Validate requested face index and handle negative face indices. * src/sfnt/sfwoff2.h (woff2_open_font): Add parameter `num_faces' to declaration.
bb7668d7	2019-07-28T19:38:05	[woff2] Improve memory and error handling. Free up memory after use, and improve error handling. * src/sfnt/sfwoff2.c (reconstruct_font, woff2_open_font): Implement changes.
1e020768	2019-07-18T01:50:16	[woff2] Avoid too many calls to `FT_REALLOC'. We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction.
4d9b3d1d	2019-07-16T02:45:03	[woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'.
e3953e54	2019-07-13T03:14:17	[woff2] Reconstruct transformed `glyf' table. Reconstruct `glyf' table if it is transformed in the uncompressed table stream. Also add necessary structures, macros and functions. * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, WOFF2_SubstreamRec, WOFF2_PointRec): New structures. (WOFF2_TableRec): s/OrigLength/dst_length/. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use `FT_SET_ERROR' to set implicit `error' variable. (WRITE_SHORT): New macro. (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to refer to substreams of the transformed `glyf' tables. (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions. (reconstruct_font): Call `reconstruct_glyf'. * src/sfnt/sfwoff2.h: Add required constants. * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'.
81cf5326	2019-07-06T18:05:18	[woff2] Copy un-transformed tables to sfnt stream. Copy un-transformed tables to the sfnt stream. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. (write_buf): New function. Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking.
106bacf5	2019-07-05T01:09:52	[woff2] Create stream for uncompressed buffer. Uncompressed buffer is now an `FT_Stream'. Perform basic checks and start iterating over tables. * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): New functions. (reconstruct_font): Modify parameters and iterate over tables. (woff2_open_font): Updated.
18f6ff11	2019-07-01T01:29:30	[woff2] Handle TTCs and start reconstructing font. We `handle' TTCs by modifying the `indices' array to point to only those tables that are part of the requested `face_index'. Set and use `num_tables' in `WOFF2_TtcFont'. * src/sfnt/sfwoff2.c (reconstruct_font): New function. (woff2_open_font): Start reconstruction of font.
7a1639bc	2019-06-30T20:01:20	[woff2] Get known tags from function. Change `KnownTags' to a function (`woff2_known_tags'). This avoids introducing a global constant array. This function returns the specified index without any checks. The caller must ensure that `index' is within array limits. * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' notation to `woff2_known_tags( ... )'. * src/sfnt/woff2tags.c: Perform changes. * src/sfnt/woff2tags.h: Update definitions.
c6c2c0b5	2019-06-30T19:32:27	[woff2] Minor. * src/sfnt/sfwoff2.c (woff2_uncompress): Add error message (woff2_open_font): Free `uncompressed_buf'.
fc65d45a	2019-06-30T04:31:04	[woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'. (compute_first_table_offset): Fix return type. * src/sfnt/sfwoff2.h (woff2_open_font): Modify declaration.
76c64f6b	2019-06-24T01:07:18	[woff2] Write SFNT Offset table. * src/sfnt/sfwoff2.c (WRITE_USHORT, WRITE_ULONG): New macros. (compare_tags): New function. (woff2_open_font): Implement it.
e09fe4cc	2019-06-18T19:58:55	* src/sfnt/sfwoff2.c: #undef macros.
e496cb29	2019-06-16T18:56:18	[woff2] Read table and collection directory. * include/freetype/internal/wofftypes.h (WOFF2_TtcFontRec): New structure. (WOFF2_HeaderRec): Add more fields. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128, ROUND4): New macros. (Read255UShort, CollectionHeaderSize, compute_first_table_offset): New functions. (ReadBase128): Use `FT_READ_BYTE'. (woff2_open_font): Add functionality to read table directory and collection directory (if present).
8c1e3fc3	2019-06-16T18:40:48	[sfnt] Include `woff2tags.c' for building. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `woff2tags.c'. * src/sfnt/sfnt.c: Include `woff2tags.c'.
b45c7dd5	2019-06-16T17:55:59	[sfnt] Add WOFF2 constants. Add constants required for WOFF2, and known table tags as defined in the specification. See https://www.w3.org/TR/WOFF2/#table_dir_format for details. * src/sfnt/woff2tags.c, src/sfnt/woff2tags.h: New files.
2fa573c1	2019-06-12T00:21:20	[sfnt] Read WOFF 2 header. Check for WOFF2 tag, call `woff2_open_font', and implement it to read header according to specification. * include/freetype/internal/fttrace.h: Add `sfwoff2.c'. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `sfwoff2.c'. * src/sfnt/sfnt.c: Include `sfwoff2.c'. * src/sfnt/sfobjs.c (sfnt_open_font): Check for `wOF2' tag and call `woff2_open_font'. * src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h: New files.
b110acba	2019-07-12T11:36:12	[sfnt, winfonts] Avoid memory leaks in case of error (#56587). * src/sfnt/sfwoff.c (woff_open_font): Call `FT_FRAME_EXIT' in case of error. * src/winfonts/winfnt.c (fnt_face_get_dll_font): Ditto.
7b275a5a	2019-05-30T23:57:34	[sfnt] Separate WOFF sources and headers. Move WOFF sources and headers to separate files. * include/freetype/internal/wofftypes.h, src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: New files. * include/freetype/internal/fttrace.h: Register `sfwoff.c'. * include/freetype/internal/internal.h: Define FT_INTERNAL_WOFF_TYPES_H. * include/freetype/internal/sfnt.h: Include FT_INTERNAL_WOFF_TYPES_H. * include/freetype/internal/tttypes.h: Move out WOFF structures. * src/sfnt/rules.mk: Add `sfwoff.c'. * src/sfnt/sfnt.c: Include `sfwoff.c'. * src/sfnt/sfobjs.c: Include `sfwoff.h', move out WOFF sources.

[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`.

Revert "[sfnt] Fix crash in `Load_SBit_Png` on Windows x64." This reverts commit dbf9142f7e0432c9ed618b3276e2b61fa39e7262, as discussed in #1037.

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`

[woff2] Support `hmtx' reconstruction when `glyf' is untransformed. `reconstruct_hmtx' requires `info->x_mins' and `info->num_glyphs' to reconstruct the hmtx table. In case glyf is not transformed, we call `get_x_mins' which does the necessary work. * src/sfnt/sfwoff2.c (get_x_mins): New function. (reconstruct_font): Call get_x_mins.

[sfnt] Support `face->num_faces' for WOFF2 fonts. Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'.

[woff2] Avoid too many calls to `FT_REALLOC'. We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction.

2019-07-16T02:45:03

[woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'.

(Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions.

Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking.

[woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function.
