2021-11-26 Alexei Podtelezhnikov <[email protected]>
[truetype] Quietly reject out-of-spec `hdmx` tables.
The `hdmx` table is optional and can be safely rejected without
an error if it does not follow specifications. The record size
must be equal to the number of glyphs + 2 + 32-bit padding.
* src/truetype/ttpload.c (tt_face_load_hdmx): Thoroughly check
the record size and improve tracing.
2021-11-23 Alexei Podtelezhnikov <[email protected]>
[truetype] Partly revert 5b626281.
Fixes #1118.
* src/truetype/ttpload.c (tt_face_load_hdmx): Do not assume that
`record_size` is rounded even though the records are padded.
2021-11-23 Alexei Podtelezhnikov <[email protected]>
* builds/windows/vc2010/freetype.vcxproj (DlgCopy): Use transforms.

Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=38562
2021-11-20 Alexei Podtelezhnikov <[email protected]>

* src/smooth/ftgrays.c (FT_Trace_Enable, FT_Trace_Disable)[STANDALONE_]:
Define.
2021-11-20 Werner Lemberg <[email protected]>
Avoid undefined left-shifts.
We really have to use double casts to avoid issues with C's and C++'s
signedness propagation rules in implicit casts.
Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41178
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41182

FT_REINTERPRET_CAST): Modify macro to take two arguments.
Update all callers.
(FT_STATIC_BYTE_CAST): New macro.
* include/freetype/freetype.h (FT_ENC_TAG): Use `FT_STATIC_BYTE_CAST`.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG): Ditto.
Use `FT_Tag` for casting.
* src/ftraster/ftmisc.h (FT_MAKE_TAG): Removed, no longer needed.
(FT_STATIC_BYTE_CAST): New macro.
* src/smooth/ftgrays.c (FT_STATIC_CAST): Replace with...
(FT_STATIC_BYTE_CAST): ... this.
2021-11-18 Werner Lemberg <[email protected]>
Provide C++ versions for public macros with casts.
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`. While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.
* include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_,
FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`.
Correctly handle negative 'signed char' input.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG, FT_BOOL): Ditto.
* include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): Use
`FT_REINTERPRET_CAST`.
* src/smooth/ftgrays.c (FT_STATIC_CAST)[STANDALONE_]: New macro.
[!STANDALONE]: Include `FT_CONFIG_CONFIG_H`.
Fixes #1116.
2021-11-16 Werner Lemberg <[email protected]>
Fix clang++ warnings.
* src/*: Initialize some variables to NULL.
2021-11-16 Werner Lemberg <[email protected]>
[truetype] Updates for the forthcoming OpenType 1.9 standard (2/2).
* src/truetype/ttgxvar.c (ft_var_load_item_variation_store):
s/shortDeltaCount/wordDeltaCount/ (as done in the specification, too).
Recognize new format and reject it for now.
2021-11-16 Werner Lemberg <[email protected]>
[truetype] Updates for the forthcoming OpenType 1.9 standard (1/2).

[mm] Tolerate missing Blend dictionary entries
In a Multiple Master font, the Blend dictionary must contain valid
Private, FontInfo, and FontBBox. The current code will error if any of
these are present and invalid, but will not error and will provide
uninitialized data if the Blend dictionary exists but does not contain
one of these entries. This change reverts to the older behavior of
treating any missing entries as containing all zero data and not
returning an error.
In the future it may be best to keep track of when these are actually
initialized and error if they are not.

[mm] Delay setting blend weight and design position.
Previously the `blend->weight_vector`, `blend->default_weight_vector`,
and `blend->design_pos` were set early to allocated but uninitialized
memory under the assumption that the memory would eventually be
initialized. However, it is possible that some of the required
keywords may not actually be present, leaving the memory uninitialized.
This is different from a present but invalid table, which would produce
an error.

* src/cff/cffload.c, src/cff/cffobjs.c: Ditto.
* src/winfonts/winfnt.c: Ditto.
2021-09-23 Werner Lemberg <[email protected]>
Minor documentation fixes and improvements.
2021-09-23 Alexei Podtelezhnikov <[email protected]>

[bdf, pcf] Minor optimization.
* src/pcf/pcfread.c (pcf_load_font): Do not call `FT_MulDiv` for a
small job.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Ditto.
* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a comment.
2021-09-22 Alexei Podtelezhnikov <[email protected]>
[base] Initialize stream memory earlier.
With Windows memory management tracking heap, it is important to use
it during the stream opening fallback. In Unix, the argument is
unused, but it is better to set it correctly.
* src/base/ftobjs.c (FT_Stream_New): Set memory before calling
`FT_Stream_Open`.
* builds/windows/ftsystem.c, builds/unix/ftsystem.c (FT_Stream_Open,
ft_close_stream_by_free): Call `ft_alloc` and `ft_free` with proper
memory argumment.

[builds/windows] Revert back to `CreateFileA` only.
Calling `CreateFileW` without making sure that the patname is really
`wchar_t` is a bad idea and can lead to unpredictable overreads. For
Windows CE, we impelemnt the missing API.
Fixes #1098 and !76 again.
* builds/windows/ftsystem.c (FT_Stream_Open): Call `CreateFileA`.
[_WIN32_WCE] (CreateFileA, FileSizeEx): Implement missing interfaces.
2021-09-21 Alexei Podtelezhnikov <[email protected]>
* src/bdf/bdflib.c (_bdf_parse_{start,glyphs}): Use appropriate scanner.
2021-09-21 Alexei Podtelezhnikov <[email protected]>
Minor.
2021-09-20 Alexei Podtelezhnikov <[email protected]>
* src/cff/cffdrivr.c (cff_ps_get_font_{info,extra}): Use FT_QNEW.
2021-09-18 Alexei Podtelezhnikov <[email protected]>
[cache] Minor clean-ups.
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Remove parantheses.
* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
(FTC_Cache_RemoveFaceID): Remove unnecessary variable.
2021-09-17 Alexei Podtelezhnikov <[email protected]>
[builds/windows] Try both wide and narrow `CreateFile`
Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
filenames using alternative -A and -W API. We'll try them both
when opening a file. This means that you should not worry about
about conversions.
Fixes #1098 and !76.
* builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
`CreateFile` in the case of failure.
2021-09-17 Edwin Steiner <[email protected]>
[cff] Explicitly set StandardEncoding or ExpertEncoding offsets.
Fixes #1097.
* src/cff/cffload.c (cff_encoding_load): Set special offset values.
2021-09-16 Alexei Podtelezhnikov <[email protected]>
[cache] Miscellaneous clean-ups.
* src/cache/ftccache.c (ftc_get_top_node_for_hash, FTC_Cache_Clear):
Remove barely used variables.
(ftc_cache_add): Adjust casting.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Remove casting.
* src/cache/ftcsbits.c (ftc_snode_load): Remove casting.
2021-09-16 Alexei Podtelezhnikov <[email protected]>
* src/cff/cffload.c (cff_fd_select_get): Remove casting.
2021-09-16 Alexei Podtelezhnikov <[email protected]>
* src/pcf/pcfread.c (pcf_read_TOC): Remove casting.
2021-09-15 Alexei Podtelezhnikov <[email protected]>
Minor type adjustments.
* src/cff/cffobjs.c (cff_face_init): Reduce casting.
* src/truetype/ttobjs.c (tt_size_ready_bytecode): Ditto.
* src/type1/t1load.c (T1_Set_MM_Design): Ditto.
