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.

Ben Wagner 188019eb 2023-01-17T16:04:30 [base] Return error if requested driver is not found. In `open_face_from_buffer` it is possible that a driver is requested but FreeType was built without the requested module. Return an error in this case to indicate that the request could not be satisfied, rather than trying all existing driver modules. * src/base/ftobjs.c (open_face_from_buffer): Return `FT_Err_Missing_Module` if a driver is specified but not found.

Ben Wagner 29f83d1d 2023-01-12T23:45:12 [base] 'close' callback may not use `stream->memory`. The documentation for `FT_StreamRec::memory` states that it 'shouldn't be touched by stream implementations'. This is true even for internal implementations of the 'close' callback, since it is not guaranteed that `memory` will even be set when the 'close' callback occurs. * src/base/ftobjs.c (new_memory_stream): stash current `memory` in `stream->descriptor`. (memory_stream_close): Use it.
Ben Wagner 0d4f887c 2023-01-12T22:43:08 [base] Always close user-provided stream. The `FT_Open_Face` documentation states > If `FT_OPEN_STREAM` is set in `args->flags`, the stream in `args->stream` > is automatically closed before this function returns any error (including > `FT_Err_Invalid_Argument`). However, if the user provides a stream in `args.stream` with `FT_OPEN_STREAM` set and a `close` function, but then for some reason passes NULL for `aface` and a non-negative `face_index`, the error `Invalid_Argument` is returned but the `close` callback will not be called on the user-provided stream. This may cause resource leaks if the caller is depending on the `close` callback to free resources. The difficulty is that a user may fill out a `FT_StreamRec` and pass its address as `args.stream`, but the stream isn't really 'live' until `FT_Stream_New` is called on it (and `memory` is set). In particular, it cannot really be cleaned up properly in `ft_open_face_internal` until the stream pointer has been copied into the `stream` local variable. * src/base/ftobj.c (ft_open_face_internal): Ensure that user-provided `args.stream.close` is called even with early errors.
Ben Wagner 13983b05 2023-01-11T14:47:26 [base] Fix leak of internal stream marked external. `open_face_from_buffer` allocates a new `FT_Stream` to pass to `ft_open_face_internal`. Because this is an `FT_OPEN_STREAM`, `ft_open_face_internal` will mark this as an 'external stream', which the caller must free. However, `open_face_from_buffer` cannot directly free it because the stream must last as long as the face. There is currently an attempt at this by clearing the 'external stream' bit after `open_face_from_buffer` returns successfully. However, this is too late as the original stream may have already been closed and the stream on the face may not be the same stream as originally passed. It is tempting to use `FT_OPEN_MEMORY` and let `ft_open_face_internal` create the stream internally. However, with this method there is no means to pass through a 'close' function to the created stream to free the underlying data, which must be owned by the stream. A possibility is to check on success if the stream of the face is the same as the original stream. If it is then unset the external flag. If not, then free the original stream. Unfortunately, while no current implementation does so, it is possible that the face still has the original stream somewhere other than as the `FT_FaceRec::stream`. The stream needs to remain available for the life of the face or until it is closed, whichever comes earlier. The approach taken here is to let the stream own itself. When the stream is closed it will free itself. * src/base/ftobjs.c (memory_stream_close): Free `stream`. (open_face_from_buffer): Simplify error handling, since `ft_open_face_internal` always closes `args.stream` on any error. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54930
Werner Lemberg 6a179ff7 2023-01-16T16:38:56 sr/*.c: Various minor fixes. * src/autofit/ft-hb.c (_hb_ft_reference_table): Call `FT_UNUSED` after variable declarations. * src/gxvalid/gxvjust.c (gxv_just_widthDeltaClusters_validate): Eliminate unused variable. * src/gzip/ftgzip.c: Don't call GCC '-Wstrict-prototypes' pragma for C++ compiler. * src/sfnt/ttcolr.c (ENSURE_READ_BYTES): Remove final semicolon to avoid compiler warning. * src/sfnt/ttsvg.c (tt_face_load_svg_doc): Fix signedness warning.
Dominik Röttsches 2692b321 2023-01-03T17:19:02 [sfnt] Remove temporary runtime flag for variable 'COLR' v1. Fixes #1187. * src/sfnt/ttcolr.c (top level, read_paint, tt_face_load_colr, tt_face_free_colr, get_deltas_for_var_index_base, tt_face_get_color_glyph_clipbox, tt_face_get_colorline_stops): Remove macro definition `VARIABLE_COLRV1_ENABLED` and its usage. * src/truetype/ttdriver.c (tt_property_set): Remove parsing of 'TEMPORARY-enable-variable-colrv1' property name. * src/truetype/ttobjs.h (TT_DriverRec): Remove `enable_variable_colrv1` flag.
Werner Lemberg b1c90733 2023-01-07T07:40:12 * src/autofit/ft-hb.c (_hb_ft_reference_table): Minor integration fixes.
Ben Wagner 3481b154 2023-01-05T21:07:26 [truetype] Reset cvt and storage in context load. Currently the cvt and storage are saved and restored in `TT_RunIns`. However, this is too granular as the cvt and storage area should be set to the original cvt and storage area only when setting up the hinting context. This allows for the cvt and storage area to be modified while parsing multiple glyphs, as is the case with composite glyphs. * src/truetype/ttinterp.h (TT_ExecContextRec): Remove `origCvt` and `origStorage`. * src/truetype/ttinterp.c (TT_RunIns): Don't save and restore the cvt and storage area. (Modify_CVT_Check, Ins_WS): Switch from "if in glyph and using original data do copy on write" to "if in glyph and not using glyph specific data do copy on write".
Matthias Clasen ebe7e912 2023-01-02T20:13:22 [autofit] Don't depend on 'hb-ft'. The circular dependency is still there, but at least we no longer depend on the HarfBuzz API that is only present if HarfBuzz has been built with FreeType support, making the bootstrapping a bit easier. * src/autofit/ft-hb.c, src/autofit/ft-hb.h: New files, providing `_hb_ft_font_create`, which is more or less a verbatim copy of the corresponding HarfBuzz code from file `hb-ft.cc`. * src/autofit/afglobal.c (af_face_globals_new): Use it. * src/autofit/afshaper.h: Don't include `hb-ft.h` but `ft-hb.h`. * src/autofit/autofit.c: Include `ft-hb.c`. * LICENSE.TXT: Updated.
Ben Wagner 262b47ac 2023-01-05T15:24:25 [truetype] Keep variation store consistent. `tt_var_load_item_variation_store` fills out a `GX_ItemVarStore`. While it may return an error, the item store must be left in a consistent state so that any use or destruction of the item store can properly use or free the data in it. Before this change the counts from the font data were read directly into the item store before the actual allocation of the arrays to which they referred. There exist many opportunities between the time the counts are read and the arrays are allocated to return early due to invalid data. When this happened the item store claimed to have entires it actually did not, leading to crashes later when it was used. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54449 * src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Read the counts into local variables and store them in the item store only after the related arrays are actually created on the item store.
Ben Wagner 15afb554 2023-01-05T12:42:55 [base] Report used stream's external status. In `open_face` the initial stream is set on the face, along with the information about if FreeType is the owner of the stream object itself. The loaders may in the course of their work replace this stream with a new stream (as is the case for 'woff' and 'woff2'), which may have a different ownership than the initial stream object (likely the original stream object is owned by the user and is external, while the new stream object is created internally to FreeType and is internal). When the stream is replaced, the face's flags are updated with the new ownership status. However, `open_face` cannot itself free this stream as its caller `ft_open_face_internal` is responsible for this. In addition, in the case of an error `open_face` cannot return an actual face with the new stream and its ownership status to the caller. As a result, it must pass this information back to the caller as a sort of "failed face" so that the caller can clean up. `open_face` was already passing back the new stream but was not passing back the stream ownership information. As a result the stream may not have been free'd when needed. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54700 * src/base/ftobjs.c (open_face): Pass back the ownership information as well. (ft_open_face_internal): Updated.

Loïc Yhuel b37b8d2a 2022-11-14T11:29:20 [meson] Fix generated ftmodule.h The sdf module wasn't recognized, so the generated ftmodule.h had "None_renderer_class". * builds/meson/parse_modules_cfg.py: Handle sdf in RASTER_MODULES.
Loïc Yhuel 63ccaef0 2022-11-14T11:36:25 [meson] Use generated ftmodule.h ftmodule.h is generated at the root of the build directory, but FT_CONFIG_MODULES_H (freetype/config/ftmodule.h) is used instead. This makes the build fail when disabling modules in modules.cfg. * meson.build (harfbuzz_dep): Add '-DFT_CONFIG_MODULES_H=<ftmodule.h>'.
Dominik Röttsches ba4bd5b9 2022-11-07T10:52:33 Add `TT_CONFIG_OPTION_NO_BORING_EXPANSION` configuration macro.

Behdad Esfahbod e97cb9e8 2022-11-09T15:42:25 [truetype] Improve bounds checks for `ItemVariationStore`. * src/truetype/ttgxvar.c (tt_hvadvance_adjust): Move bounds check ... (tt_var_get_item_delta): ... to this function, because it is safer. For example, the 'avar' table 2.0 codepath was not performing a bounds check at all.
Behdad Esfahbod 9be958ca 2022-11-09T15:41:34 [truetype] In `ItemVariationStore`, value 0xFFFF for `dataCount` is valid. It corresponds to outer indices of 0 to 0xFFFE. * src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Remove invalid code.

Ben Wagner 9154707f 2022-11-07T16:58:56 [truetype] Check avar_segment before access * src/truetype/ttgxvar.c (tt_done_blend): check `avar_segment` before accessing to free its `correspondence`. Reported as: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=53062
Ben Wagner d38407f7 2022-11-07T15:11:37 [truetype] Restore behavior of ft_var_load_hvvar * src/truetype/ttgcvar.c (ft_var_load_hvvar): restore previous behavior In a previous change [0] the behavior of `ft_var_load_hvvar` was changed to not load the item variation store if it was at offset 0, but not return an error when this happened. This broke any users, like `tt_hvadvance_adjust`, that rely on successful completion of `ft_var_load_hvvar` to imply that returned table's `itemStore` had been initialized. This lead such users to dereference NULL. This change appears to have been unintentional and unrelated to the actual avar2 changes. As a result, fix these NULL dereferences by restoring the code to always attempt to initialize the `itemStore`. [0] ae4eb996 "[truetype] Add support for `avar` table 2.0 format."

suzuki toshiya bccf1cd6 2022-10-16T18:02:27 [build] use AC_CHECK_PROG() macro for libpng-config detection * builds/unix/configure.raw: use AC_CHECK_PROG() instead of `which` to find `libpng-config`.
suzuki toshiya 32cfab4b 2022-10-10T14:22:12 [build] fix for make multi Fix "make multi" by MR !223 * include/freetype/internal/services/svmm.h: include ftmm.h to define FT_Get_MM_Func. * src/truetype/ttgxvar.h: include ftmmtypes.h to use GX_AVarTable properly. * src/base/ftmac.c: include ftdebug.h to use FT_THROW() properly.
Alexei Podtelezhnikov e00afdb3 2022-11-07T21:36:32 * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Accelerate the search. This is mostly for consistency because PFR fonts with bitmap strikes do not seem to exist.
Alexei Podtelezhnikov 6139f2b6 2022-11-06T13:12:47 [bdf, pfr, psnames] Accelarate charmap searches. The binary searches within charmaps can be accelerated because they often contain dense continuous blocks of character codes. Within such blocks, you can predict matches based on misses. This method has been deployed in `bdf` since 0f122fef34; we only refactor it there. We now use it in `pfr` and `psnames`, which speeds up the unicode charmap access by about 50% in PFR and Type 1 fonts. * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Refactor. * src/pfr/pfrcmap.c (pfr_cmap_char_{index,next}): Predict `mid` based on the mismatch distance. * src/psnames/psmodule.c (ps_unicodes_char_{index,next}): Ditto.
Behdad Esfahbod ae4eb996 2022-07-23T13:49:27 [truetype] Add support for `avar` table 2.0 format. See https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md for the specification. Currently, this is implemented only in most recent OS versions on Apple platforms and in the HarfBuzz library, but it is expected to be added to the OpenType standard soon. * src/truetype/ttgxvar.h (GX_AVarTableRec): New structure. (GX_BlendRec): Use it to replace `avar_segment` with `avar_table`. * src/truetype/ttgxvar.c (ft_var_load_avar): Load new table version. (ft_var_to_normalized, tt_done_blend): Extend for new format. (ft_var_load_hvvar, ft_var_to_design): Updated.
Werner Lemberg dea2e635 2022-10-24T06:59:45 Replace '1/64th' (and similar entries) with '1/64' in docs and comments.
Ivan Panchenko 05e1b37e 2022-10-23T21:24:49 * include/freetype/*: Fix documentation typos.
Alexei Podtelezhnikov ffbbf3df 2022-10-21T15:55:30 * src/truetype/ttgload.c: Cosmetic changes.
Alexei Podtelezhnikov 1bfaca06 2022-10-21T07:18:06 [cff, truetype] Simplify SVG metrics scaling. Use pre-calculated scaling factors. Also, the advance widths used to be rounded, which was incorrect. * src/cff/cffgload.c (cff_slot_load): Use `x_scale` and `y_scale`. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto.
Werner Lemberg 0ec85f71 2022-10-20T13:55:41 * subprojects/zlib.wrap: Update to zlib version 1.2.13.
Dominik Röttsches 0b62c1e4 2022-10-18T14:45:43 [sfnt] Additional bounds checks for `COLR` v1 table handling. * src/sfnt/ttcolr.c (read_paint): Add `colr` argument, necessary for... ... another use of `ENSURE_READ_BYTES`. Update callers. (tt_face_get_paint_layers): Ensure that the 4-byte paint table offset can be read. This is a follow-up to !124 and issue https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=52404
Werner Lemberg af46fcc1 2022-10-18T19:40:03 [gzip] Update sources to zlib 1.2.13.
Alexei Podtelezhnikov b8882a3e 2022-10-18T15:58:02 * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Simplify calculations.
Werner Lemberg c943d408 2022-10-18T11:41:00 Minor formatting.
Dominik Röttsches 04272824 2022-10-17T18:18:49 [sfnt] Guard individual `COLR` v1 paint field reads. * src/sfnt/ttcolr.c (ENSURE_READ_BYTES): New macro. (read_paint): Use it – after the start pointer `p` has been checked for whether it allows reading the format byte, each successive paint table field read need to be bounds-checked before reading further values. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=52404
Xiang Xiao 8493877e 2022-10-05T23:06:30 * builds/toplevel.mk: Prefix all paths with `$(TOP_DIR)/`. This is useful for builds that are not started from the root directory. Signed-off-by: Xiang Xiao <xiaoxiang@xiaomi.com>
Liu Kunpeng(柳鲲鹏) bb59c3c9 2022-10-16T22:10:19 * src/base/ftsynth.c (FT_GlyphSlot_Slant): New API with custom slant. * include/freetype/ftsynth.h (FT_GlyphSlot_Slant): Declare it.
Alexei Podtelezhnikov 3ab1875c 2022-10-14T22:06:23 Note the lack of floating-point data types.
Werner Lemberg 5182264a 2022-10-10T12:31:53 [cff] Remove `FT_CONFIG_OPTION_NO_GLYPH_NAMES`. This ancient option stayed completely undocumented. Given that the 'cff' driver requires the 'psnames' module, it makes no sense today to have this macro. * src/cff/cffdrivr.c (cff_services), src/cff/cffobjs.c (cff_face_init): Remove corresponding conditional code.
Werner Lemberg 0d66abca 2022-10-10T12:41:19 Synchronize `ftoption.h` flavours.
Werner Lemberg 141d979a 2022-10-10T12:25:51 Minor comment changes.
Alexei Podtelezhnikov 15f68734 2022-10-04T23:36:09 Improve FT_Get_Name_Index docs and place it next to FT_Get_Glyph_Name.
Alexei Podtelezhnikov 0417527d 2022-10-03T19:23:26 [autofit] Reset the face charmap directly. There is no need to validate the original charmap in `FT_Set_Charmap`. It can be reset directly. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Use direct assignment. * src/autofit/af{latin,cjk,indic}.c (af_latin_metrics_init): Ditto.
Alexei Podtelezhnikov 1b6dce84 2022-10-03T19:18:48 * src/type1/t1afm.c (T1_Read_PFM): Set charmaps directly. As with the previous commit, we can avoid the validation checks of `FT_Set_Charmap` and set it directly when choosing from the available list.
Alexei Podtelezhnikov 8faf57dd 2022-10-03T17:13:30 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Avoid `FT_Set_Charmap`. Set charmap aggressively without all validations of `FT_Set_Charmap` because we take it from the available array and only temporarily. Even CMap Format 14 will gracefully return 0.
Alexei Podtelezhnikov b93f20ab 2022-10-03T15:10:12 * src/cache/ftcbasic.c (ftc_basic_family_get_count): Remove redundancy.
Werner Lemberg de8f14a8 2022-09-30T23:25:02 * src/psaux/pshints.c (cf2_hintmap_insertHint): Fix midpoint computation. Replace '(start + end) / 2' with 'start + (end - start) / 2' to avoid overflow. Fixes #1180.
Werner Lemberg 2adb810c 2022-09-30T17:00:10 * src/psaux/pshints.c (cf2_hintmap_build): Improve debugging output.
