d1c20005	2021-08-28T07:29:05	[truetype] Fix compilation if !TT_CONFIG_OPTION_BYTECODE_INTERPRETER. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): Compile function conditionally. (tt_face_vary_cvt) [!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Add code. Fixes #1091.
50318357	2021-08-25T00:31:26	[truetype] Fix for the family name shorter than 8 characters. * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): If the family name to be checked is shorter than 8 characters, do not check its syntax.
c4fc0e69	2021-08-24T12:29:47	[truetype] Simplify `trick_names'. * src/truetype/ttobjs.c (tt_check_trickyness_family): For the case that the beginning part of a long tricky family name is already registered as another tricky family name, no need to double-check the longer one. Such long tricky family names are removed from the `trick_names'.
992382ba	2021-08-24T12:11:46	[truetype] Add 2 tricky font names. Additional fix for the issue #1087. * src/truetype/ttobjs.c (tt_check_trickyness_family): Add 2 tricky font names reported in #1087.
2b3ccd6e	2021-08-24T11:43:11	[truetype] New function to skip the randomization tag. * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): New function to skip the randomization tag in the names of the fonts embedded in a PDF. It is used by tt_check_trickyness_family(), to keep from mistaking "DLC" in the randomization tag as a tricky font name. See discussion in: https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html For technical detail about the randomization tag, please find PDF Reference 5.5.3 "Font Subsets". Thanks to Justyna Wawrzynska for pointing out the issue caused by the randomization tag.

f11f3ed1	2021-08-18T06:54:34	[base] Fix ppem size overflow. Fixes #1086. * src/base/ftobjs.c (FT_Request_Metrics): Add return value. Check whether ppem values fit into unsigned short values. (FT_Request_Size): Updated. * include/freetype/internal/ftobjs.h: Updated. * src/cff/cffobjs.c (cff_size_request), src/cid/cidobjs.c (cid_size_request), src/truetype/ttdriver.c (tt_size_request), src/type1/t1objs.c (T1_Size_Request): Updated.
d3dc2da9	2021-06-30T18:22:29	* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`. It is undefined behavior to pass `NULL` to `memcpy`. `coords' is passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design` explictly call `tt_set_mm_blend` with `coords` as `NULL`. In addition, `TT_Set_MM_Blend` has a similar possible issue.
b460a506	2021-06-19T07:03:40	[truetype] Fix integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35312 * src/truetype/ttinterp.c (Ins_JMPR): Use `ADD_LONG`.

52f2a008	2021-04-01T09:33:47	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	2021-03-31T22:31:44	[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. (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.
2149b51f	2021-03-13T19:08:09	Handle various VC++ compiler warnings. 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`.
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.
b6e8a712	2021-01-17T07:18:48	Update all copyright notices.
c6ff2556	2020-12-26T10:50:21	[sdf] Use 'counter-clockwise', not 'anti-clockwise'. We prefer US nomenclature. * src/sdf/ftsdf.c (SDF_Contour_Orientation): s/SDF_ORIENTATION-ACW/SDF_ORIENTATION_CCW/. Update all users.
f6be9276	2020-12-16T06:03:10	[truetype] Fix incremental metrics (#59503). * src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph): Previously, the code would populate the phantom points before calling the `get_glyph_metrics` callback. For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros). (tt_get_metrics_incr_overrides): Renamed to... (tt_get_metrics_incremental): ... this. Updated caller * include/freetype/ftincrem.h: Update the documentation to make it clearer that `get_glyph_metrics` is to retrieve metrics from a non-standard source, but not for the purpose of imposing custom metrics.
272ae5ee	2020-12-07T10:29:24	* src/*: More fixes for using a '\n' in `FT_TRACE` and `FT_ERROR`.
a6adb256	2020-12-02T14:15:07	* 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).
6d9e6b21	2020-08-28T09:56:38	* src/*: Fix `-Wformat` warnings.

f9f6adb6	2020-08-05T08:24:15	[truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND. For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set FT_OUTLINE_OVERLAP to render them with direct oversampling, which mitigates artifacts (see 3bb512bc9f62). * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): Redefine to rhyme with OVERLAP_SIMPLE. * src/base/ftgloadr.c (FT_GlyphLoader_Rewind): Reset outline flags. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Retain OVERLAP_SIMPLE. (load_truetype_glyph): Retain OVERLAP_COMPOUND.

16586859	2020-06-13T21:15:45	Remove redundant inclusion of `ft2build.h'. * /: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
e1339133	2020-06-08T13:31:55	Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. /: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.
4eee1340	2020-05-18T09:16:12	Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.
a45da253	2020-05-08T10:59:37	* src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000.
11975fe9	2020-02-29T20:18:00	Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure.
216e0776	2020-02-28T07:43:00	[truetype] Add better checks for loading `gvar' table (#57905). * src/truetype/ttgxvar.c (ft_var_load_gvar): Delay settings of any `blend->xxxcount' values until the corresponding data has been checked. Also do some sanitizing to avoid a too early exit. (TT_Vary_Apply_Glyph_Deltas): Improve tracing message.
4a19a53d	2020-02-04T13:37:19	* src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#57732). The font that exceeds the old limit is Constantine, version 1.001.

b0522701	2019-05-16T12:52:57	[truetype] Actually scale varied CVT values. Up to now, only the unscaled CVT values were varied; in other words, the `CVAR' data was never used for bytecode hinting. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): New auxiliary function. (tt_face_vary_cvt): Use it to trigger rescaling of CVT values.
37580053	2019-05-16T12:15:54	[truetype] Use 26.6 format for storing unscaled CVT values. If `CVAR' data is applied to variation fonts, fractional values are possible. * include/freetype/internal/tttypes.h (TT_FaceRec): Change type of `cvt' from `FT_Short' to `FT_Int32'. * src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro. (tt_face_vary_cvt): Use it to update code to 26.6 format. * src/truetype/ttobjs.c (tt_size_run_prep): Update code to 26.6 format. * src/truetype/ttpload.c (tt_face_load_cvt): Stora data in 26.6 format.
ac335cd5	2019-05-16T10:15:53	* src/truetype/ttgload.c (load_truetype_glyph): Init `unrounded'. This fixes linear advance width values for spacing glyphs. Bug introduced 2019-05-09.

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.

[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`.

[truetype] Fix incremental metrics (#59503). * src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph): Previously, the code would populate the phantom points before calling the `get_glyph_metrics` callback. For formats like PCL XL format 1, class 2 downloaded fonts (where metrics are removed from the TTF header), this causes problems when the hinting program uses the phantom points (misplaced and distorted glyphs) due to the metrics being unset (all zeros).

Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure.

(TT_Process_Simple_Glyph): Use it. The `unrounded' array is active for variation fonts only, thus also enclose related code with `#ifdef TT_CONFIG_OPTION_GX_VAR_SUPPORT ... #endif' where necessary. Revert commit a113e5d from 2019-05-09, and don't use `extra_points2' but allocate a temporary array. Speed up the scaling of the `unrounded' array. * src/truetype/ttgxvar.c (FT_fixedToInt, FT_FixedToFdot6): Fix type conversions and rounding.

Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
