2b672e72	2022-01-02T18:33:03	* builds/unix/configure.raw: Restore `SYSTEM_ZLIB` variable. This was accidentally removed with commit 93ebcbd0 almost eight years ago.
4eb6cb88	2021-12-25T09:23:58	Fix warnings for CMake Unity builds. * src/cache/ftcbasic.c (FT_COMPONENT): Undefine macro before redefinition. * src/smooth/ftgrays.c (TRUNC, FRACT): Ditto.
4f357118	2021-12-17T11:22:09	Clang-Tidy warning fixes. * src/base/ftobjs.c (FT_Get_Paint): Operator has equivalent nested operands. * src/bdf/bdflib.c (_bdf_add_property): Value stored to `fp` is never read. * src/sdf/ftbsdf.c (bsdf_init_distance_map): Value stored to `pixel` is never read. * src/sdf/ftsdf.c (split_sdf_shape): Value stored to `error` is never read.
d6a5c577	2021-12-13T23:40:16	* meson.build: Optimize lookup for `python3` program. The python module's `find_installation` method is intended to provide routines for compiling and installing python modules into the `site-packages` directory. It does a couple of slow things, including run an introspection command to scrape sysconfig info from the detected interpreter, which are not needed for the sole use case of invoking the found installation as an executable. Furthermore, when invoked without the name or path of a python binary, it is hardcoded to always look for `python3` corresponding to the interpreter meson itself uses to run. So using `find_installation` did not even allow detecting `python2` as a fallback. Instead, switch to a simple `find_program` lookup that finishes as soon as the program is found.
57fd6180	2021-12-13T23:33:03	* builds/meson/*.py: Fix name of python executable for auxiliary scripts. The previous change to check the return code of `run_command` invocations caused the CI to fail. Although most scripts used `python_exe` as the program command, the script to determine the project version did not. But, all scripts used `python` as the shebang, and this is not available on all systems. Particularly Debian does not provide a `python` command, though `python3` does exist. This meant that formerly the version number was lacking, and now the build simply fails. Instead, rely on `python3` since it is guaranteed to exist when running meson, and `python2` is end of life anyway.
e342f83c	2021-12-13T22:50:18	* meson.build: Check the return value of `run_command`. By default, errors are not checked and a command that is somehow broken will just capture incorrect output (likely an empty string). Current development versions of meson now raise a warning for this implicit behavior, and advise explicitly setting the `check:` keyword argumend to determine whether a failing return code should be considered an error. Since none of the commands in this project are expected to fail, mark them as required to succeed.
0da2a115	2021-12-13T11:44:24	[truetype] Upstream the hdmx binary search. * src/truetype/ttobjs.h (TT_SizeRec): Add `widthp` for the hdmx widths. * src/truetype/ttobjs.c (tt_size_reset): Initialize `widthp` even though it might never be used by the interpreter. * src/truetype/ttgload.c (tt_loader_init): Avoid repeated searches in the hdmx table.
fd03dcc1	2021-12-12T12:29:04	[truetype] Reset the IUP-called flags for each subglyph. This fixes fall-out from 7809007a5b88b15, where the composite accents were no longer hinted. * src/truetype/ttgload.c (ttloader_init): Move the IUP-called flag initialization from here... * src/truetype/ttinterp.c (TT_Run_Context): ... to here.
7add5b2b	2021-12-11T22:54:06	[truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances.
a8ef33e3	2021-12-11T22:42:46	[truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable. This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY is specified by FT_Get_Advances and the `hdmx` data are located. Particularly, the classic v35 interpreter or "verified" ClearType fonts might see 100x speed up in retrieving the hdmx cache. * src/truetype/ttgload.c (TT_Load_Glyph): Insert the shortcut.
6c831d65	2021-12-11T22:34:27	[truetype] Initialize the loader with `hdmx` data. The `hdmx` matching can be done before the glyph is loaded. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field. * src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx` code from here... (tt_loader_init): ... to here, before the glyph is loaded.
7809007a	2021-12-11T22:22:57	[truetype] Relocate subpixel flag setting. `TT_RunIns` is too busy to deal with subpixel flags. It is better to set them in `tt_loader_init`, which is executed before each glyph program. * src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from here... * src/truetype/ttgload.c (tt_loader_init): ... to here.
a35b081e	2021-12-11T22:12:25	[truetype] Limit INSTCTRL appication within specs. * src/truetype/ttinterp.c (Ins_INSTCTRL): Limit its global effects to the CVT program and local effects to the glyph program. This also fixes an Infinality buglet. The `ignore_x_mode` should be locally unset by the glyph program.
bad92be9	2021-12-09T17:06:28	[bdf] Fix use of uninitialized value. In _bdf_readstream if the data contained no newline then the buffer would continue to grow and uninitialized data read until either the uninitialized data contained a newline or the buffer reached its maxiumum size. The assumption was that the line was always too long and the buffer had been filled, however this case can also happen when there is not enough data to fill the buffer. Correct this by properly setting the cursor to the end of the available data, which may be different from the end of the buffer. This may still result in one extra allocation, but only on malformed fonts. * src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove unread set of `avail`. Bug: https://lists.nongnu.org/archive/html/freetype-devel/2021-12/msg00001.html
012b00f3	2021-12-07T10:19:06	[truetype] Reduce Infinality footprint again. * src/truetype/ttgload.c (compute_glyph_metrics): Streamline and prioritize the Infinality checks to use `hdmx`.
1f951898	2021-12-06T23:08:46	[builds/windows] Guard some non-ancient API. We can support Windows 98 and NT 4.0 in principle... * builds/windows/ftdebug.c, builds/windows/ftsystem.c: Check for the ancient SDK using _WIN32_WINDOWS, _WIN32_WCE, or _WIN32_WINNT.
9a533aa2	2021-12-06T21:46:47	* builds/windows/visualc/freetype.vcproj: Add missing file.
3f83daee	2021-12-01T20:17:59	* Version 2.11.1 released. ========================== Tag sources with `VER-2-11-1'. * docs/VERSION.TXT: Add entry for version 2.11.1. * docs/CHANGES, docs/release: Updated. * README, src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.11.0/2.11.1/, s/2110/2111/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 24:1:18. * CMakeLists.txt (VERSION_PATCH): Set to 1. * builds/toplevel.mk (version_tag, CHANGELOG_SCRIPT): New variables. (do-dist): Generate `ChangeLog` file with all commits since last release.
03380482	2021-11-29T20:45:07	[builds/windows] Improve debugging. * builds/windows/ftdebug.c (FT_Message, FT_Panic): Buffer output and call `OutputDebugStringA` only if `IsDebuggerPresent`. [_WIN32_WCE] (OutputDebugStringA): Implement the missing API.
3b45f564	2021-11-29T18:17:49	* src/base/ftobjs.c (FT_Request_Metrics): Fix build warning on Android. Use casts since `FT_USHORT_MAX` is unsigned short in bionic (libc used in Android).
64e26ad3	2021-11-27T22:31:17	* builds/windows/vc2010/freetype.vcxproj (DlgCopy): Minor tweak.
36a905e1	2021-11-26T09:15:46	* src/truetype/ttpload.c (tt_face_load_hdmx): Added comments.
32f13c11	2021-11-25T22:38:40	[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.
cff026d4	2021-11-23T16:05:12	[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.
99086bf2	2021-11-23T16:02:02	* builds/windows/vc2010/freetype.vcxproj (DlgCopy): Use transforms.
3cabd142	2021-11-22T19:36:45	Update `CHANGES` files, other minor whitespace and documentation issues.

a11650d7	2021-11-21T07:51:31	* src/truetype/ttinterp.c (Ins_MD): Avoid `FT_ABS`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=38562
f8a4163a	2021-11-20T07:01:26	* include/freetype/fttypes.h (FT_MAKE_TAG): Remove the same casting.
6da5f95f	2021-11-20T09:29:09	[gxvalid] Fix minor compilation warning. * src/gxvalid/gxvmort5.c (gxv_mort_subtable_type5_subtable_setup): Declare as static.
f5ce1824	2021-11-20T07:56:34	[smooth] Fix stand-alone compilation. * src/smooth/ftgrays.c (FT_Trace_Enable, FT_Trace_Disable)[STANDALONE_]: Define.
8c8f51c5	2021-11-19T21:50:22	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 * include/freetype/config/public-macros.h (FT_STATIC_CAST, 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.
9079c5d9	2021-11-13T08:53:19	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.
238245cd	2021-11-16T22:07:28	Fix clang++ warnings. * src/*: Initialize some variables to NULL.
e4f7673e	2021-11-13T21:11:00	[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.
93e6b3e8	2021-11-13T14:41:40	[truetype] Updates for the forthcoming OpenType 1.9 standard (1/2). This is in preparation for implementing `DeltaSetIndexMap` format 1, which is used by `COLR` v1 tables, and which allows 32bit indices. https://docs.microsoft.com/en-us/typography/opentype/otspec190/delta/otvarcommonformats_delta.html * src/truetype/ttgxvar.h (GX_DeltaSetIdxMapRec): Change type of `mapCount` to `FT_ULong`. * src/truetype/ttgxvar.c (ft_var_load_delta_set_index_mapping): Add argument for passing the table size; update caller. Implement new format.
d31bafcb	2021-11-14T11:02:54	Fix clang warnings. * src/gxvalid/gxvcmmn.h (GXV_SET_ERR_IF_PARANOID): Use 'do' block. * src/gxvalid/gxvmod.c (GXV_TABLE_LOAD, GXV_TABLE_VALIDATE): Ditto. * src/smooth/ftgrays.c (gray_convert_glyph): Add cast. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Remove cast. * src/type1/t1load.c (read_binay_data): Use `FT_ULong` for `size` parameter. (parse_subrs, parse_charstrings, parse_dict): Ditto; also add some casts.
9597fd7b	2021-11-11T17:33:37	[sfnt] Avoid undefined shifts in `COLR` v1 paint parsing * src/sfnt/ttcolr.c (read_paint, tt_face_get_paint): Tighten shift behavior by using multiplication, mostly using macros from ftcalc.h. Fixes: https://bugs.chromium.org/p/chromium/issues/detail?id=1269168
cf553136	2021-11-12T22:27:18	[builds/windows] Improve `DlgCopy` target. Fixes #1113. * builds/windows/vc2010/freetype.vcxproj: Run `DlgCopy` conditionally and decouple it from `Build`.
42e61723	2021-11-11T23:06:36	Explicitly define `FT_MSB` for Clang. * include/freetype/internal/ftcalc.h [__clang__] (FT_MSB): Updated.
c5cd2a3d	2021-11-10T08:46:26	* src/truetype/ttgxvar.c (ft_var_to_normalized): Edge optimization.
188c7d66	2021-11-09T22:47:26	Additional `FT_MSB` macro definitions. Better macros for Windoes CE and ARM in general, based on !109 from metarutaiga. * include/freetype/internal/ftcalc.h [_MSC_VER] (FT_MSB): Updated.
05089e8a	2021-11-08T22:33:12	[build/windows] Remove logging from default debug configurations. DLG is rather costly for performance and should be used judiciously. This removes it from the default configurations but gives an example how to enable it using the `UserDefines` property. * builds/windows/vc2010/freetype.vcxproj: Hide FT_DEBUG_LOGGING.
d899b200	2021-11-08T12:27:04	* src/sfnt/sfobjs.c (sfnt_open_font): Fix typo.
b86f96bc	2021-11-08T11:15:50	* src/gxvalid., src/otvalid.: Fix `-Wformat` warnings.
cce78228	2021-11-08T09:41:54	[pshinter] Fix C++ compilation. * src/pshinter/pshalgo.c (psh_compute_dir): Fix type of `result`. (psh_hint_table_find_strong_points): Add cast.
7ef26604	2021-11-04T09:10:57	[sfnt] Reduce footprint if WOFF and WOFF2 support is not needed. Based on a patch from metarutaiga (MR !106). The gist of this commit is that it doesn't make sense to support WOFF without compression (which would be only possible in WOFF 1.0 anyway). * src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with `FT_CONFIG_OPTION_USE_ZLIB` block. Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block. * src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with `FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code. * src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c, src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks, not parts of the code. Fixes #1111.
bb4e049a	2021-11-04T08:58:13	[truetype] Make trickyness checks depend on TT_USE_BYTECODE_INTERPRETER. Based on a patch from metarutaiga (MR !106). * src/truetype/ttobjs.c (tt_skip_pdffont_random_tag, tt_check_trickyness_family, tt_synth_sfnt_checksum, tt_get_sfnt_checksum, tt_check_trickyness_sfnt_ids, tt_check_trickyness): Put functions into a `TT_USE_BYTECODE_INTERPRETER` block. (tt_face_init): Put trickyness checks into a `TT_USE_BYTECODE_INTERPRETER` block. Fixes #1111.
9ebdc9cb	2021-11-07T23:21:40	* src/sfnt/ttload.c (tt_face_load_gasp): Fix a type mismatch warning.
7f4b9bfb	2021-11-07T10:20:16	[dlg] Define DLG_STATIC explicitly. DLG_STATIC is intended to disable Windows DLL linking attributes. It does not hurt to define it explicitly when we wrap DLG code. This fixes tons of LNK4286 and C4273 warnings from MSVC if we forget to define DLG_STATIC as a compiler option. * builds/windows/vc2010/freetype.vcxproj: Remove DLG_STATIC option. * src/dlg/dlgwrap.c [FT_DEBUG_LOGGING]: Define DLG_STATIC. * include/freetype/internal/ftdebug.h [FT_DEBUG_LOGGING]: Ditto.
c693377e	2021-11-07T10:05:05	[dlg] Lighten up the inclusions. The DLG wrapper needs to know if FT_DEBUG_LOGGING is defined in `ftoption.h`. It does not need entire FreeType. * src/dlg/dlgwrap.c: Include FT_CONFIG_OPTIONS_H directly.
cb9e7b7a	2021-11-06T22:59:31	[truetype] Avoid some memory zeroing in variations. * src/truetype/ttgxvar.c (ft_var_readpackeddeltas, ft_var_load_avar, ft_var_load_item_variation_store, ft_var_load_gvar): Use FT_QNEW_ARRAY if memory immediately initialized or discarded otherwise.
fc55291b	2021-11-04T11:07:43	[truetype] Fix handling of packed deltas in Variation Fonts. * src/truetype/ttgxvar (ft_var_readpackeddeltas): Don't expect the number of bytes used to encode the deltas to be higher than the number of encoded values. The specification allows a very compact encoding; for example, a list of 200 zeros can be encoded with just a couple of bytes. We now count the consumed bytes to make sure to not read more than expected.
9ed5332f	2021-11-04T08:56:59	[truetype] Fix CVAR handling of tuples for all points. * src/truetype/ttgxvar (tt_face_vary_cvt): Function `ft_var_readpackedpoints`, when it returns `ALL_POINTS`, also sets `point_count` to value 0. However, the CVAR code was incorrectly expecting that `point_count` would be set to match the length of the CVT table.
23d1d8ad	2021-11-04T08:55:39	* src/truetype/ttgxvar.c: Fix typos in macros that guard CVAR code.
5d651faa	2021-11-03T22:43:22	* docs/INSTALL: Mention Meson and MSBuild more prominently.
e6e6cbf1	2021-11-03T10:07:20	[libpng] Update Meson wrap for win-arm64 1.6.37-5 released patches for win-arm64 to successfully build libpng with Meson: https://github.com/mesonbuild/wrapdb/pull/205 https://github.com/mesonbuild/wrapdb/pull/216 Updated by the following command: meson wrap update libpng Tested on win-arm64 and x64.
d3d3ff76	2021-11-01T17:32:27	[sfnt] Clarify `COLR` v1 FT_Paint* format representations * include/freetype/ftcolor.h (FT_PaintLinearGradient, FT_PaintRadialGradient, FT_PaintSweepGradient, FT_PaintTransform, FT_PaintTranslate, FT_PaintScale, FT_PaintRotate, FT_PaintSkew): Clarify 16.16 fixed point representation of struct fields. * src/sfnt/ttcolr.c (read_paint): Shift coordinates for FT_PaintLinearGradient, FT_PaintRadialGradient, FT_PaintSweepGradient accordingly. Fixes: https://gitlab.freedesktop.org/freetype/freetype/-/issues/1110
588a058d	2021-11-02T22:51:51	[builds/windows] Let MSBuild handle DLG copy. * builds/windows/vc2010/freetype.vcxproj: Specify DlgCopy target. * builds/windows/vc2010/script.bat: Deleted.
94cb3a2e	2021-10-29T10:31:59	* src/truetype/ttgload.c (load_truetype_glyph): Fix MSVC warning C4312.
31fd0547	2021-10-29T10:13:47	[builds/windows] Separate MSVC linker and librarian. MSVC uses LIB for static and LINK for dynamic libraries. They are related but the former has much smaller set of options. * builds/windows/vc2010/freetype.vcxproj: Updated.
79b28d37	2021-10-28T22:51:15	[builds/windows] Revise MSVC linking optimizations. * builds/windows/vc2010/freetype.vcxproj: Optimize DLL linking only. * builds/windows/visualc/freetype.dsp: Ditto. * builds/windows/visualc/freetype.vcproj: Ditto.
793c0126	2021-10-27T22:36:11	[woff] Optimize table tagging. * include/freetype/internal/wofftypes.h (WOFF_TableRec): Use 32-bit tag. * src/sfnt/sfwoff.c (woff_open_font): Use 32-bit tag.
a577bbcb	2021-10-27T22:24:27	[woff2] Optimize table tagging. Fixes #1107. * include/freetype/internal/wofftypes.h (WOFF2_TableRec): Use 32-bit tag. * src/sfnt/sfwoff2.c (compare_tags, find_table, woff2_open_font): Use 32-bit tag. * src/sfnt/woff2tags.[ch] (woff2_known_tags): Use static storage and return 32-bit tag.
80b13f57	2021-10-26T10:57:17	Formatting.
535c67dd	2021-10-25T22:38:05	[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. * src/type1/t1load.c (t1_allocate_blend): Zero initiailize.
f091e60c	2021-10-25T22:31:09	[builds/windows] Add MSVC linker optimazations. We continue to build static libraries with statically linked C run- time and add options to optimize references. * builds/windows/vc2010/freetype.vcxproj: Sort entries, add options.
92f5e15f	2021-10-23T09:43:46	* builds/windows/vc2010/freetype.vcxproj: Use MachineARM64.
5e6efd6a	2021-10-22T15:25:10	[builds/windows] Prioritize x64. * builds/windows/vc2010/freetype.sln: Sort entries.

65be4b21	2021-10-21T09:55:28	[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. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions.
b5e003f1	2021-10-21T09:48:38	[cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up. Reportd as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts into locals and update the vstore counts immediately after each entry becomes free-able.
fde91ab8	2021-10-20T11:45:15	[sfnt] Delay setting gasp ranges and count until computed. Previously, the gasp.numRanges was set and gasp.gaspRanges was allocated and assigned before a possible early exit if the frame could not be entered. It is also possible that the gaspRanges allocation could fail but the numRanges still be set to non-zero. In such cases an error would be returned, but the face would have a gasp in an inconsistent state which may still be accessed. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261450 * src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges and gasp.gaspRanges until after the ranges are initialized.
6d12e3a0	2021-10-20T11:38:16	[sfnt] Delay setting names and langTags until computed. Previously, the table->names and table->langTags fields were created pointing to uninitialized memory and an early exit could happen if the frame could not be entered. The caller would then be unable to properly dispose of the memory as the string fields had not been initialized. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261343 * src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags and table->names until after the memory they will point to is fully initialized.
e990c33f	2021-10-20T11:27:03	* tests/issue-1063/main.c: s/PATH_MAX/FILENAME_MAX/. Closes !97 for Windows by using a standard macro.
8ef8072b	2021-10-19T22:59:46	[bdf, cid, pfr, winfonts] Improve rejection of other font formats. This is mainly for better diagnostics of malformed fonts. * src/bdf/bdflib.c (_bfd_readstream): Stop font format testing if the first input line is too long or doesn't end with `\r` or `\n`. * src/cid/cidparse.c (cid_parser_new): Don't handle too short input as an error but as an unknown format. * src/pfr/pfrobjs.c (pfr_face_init): Ditto. * src/winfonts/winfnt.c (fnt_font_load, fnt_face_get_dll_font): Ditto.

c71eb22d	2021-10-15T22:18:38	Fix typos in memory macros. FT_QNEW_ARRAY and FT_QRENEW_ARRAY were using the non-Q FT_MEM_NEW_ARRAY and FT_MEM_RENEW_ARRAY. Change these to use the Q versions. Also fix the one issue discovered in tt_face_load_name where table->names is created with FT_QNEW_ARRAY but the extra string member is not initialized to NULL. * include/freetype/internal/ftmemory.h (FT_Q(RE)NEW_ARRAY): Use FT_MEM_Q(RE)NEW_ARRAY as needed. * src/sfnt/ttload.c (tt_face_load_name): Initialize `entry->string`.
8406ae53	2021-10-15T14:16:30	[truetype] Reload context after re-executing `prep`. When a different hinting mode from the current is selected, the `prep` table must be re-executed with the new mode. After this happens the context must be re-loaded in preparation for the glyph program to be run. Fixes #1104. * truetype/ttgload.c (tt_loader_init): Add call to `TT_Load_Context`.

77bd46e9	2021-10-10T23:12:12	[psaux] Signedness revisions. Unsigned indexes are easier to check. * src/psaux/cffdecode.c (cff_decoder_parse_charstrings): Updated. * src/psaux/psintrp.c (cf2_interpT2CharString): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/type1/t1load.c (read_binary_data): Ditto.
3b036820	2021-10-10T23:11:10	[cid] Signedness revisions. Unsigned checks are simpler. * include/freetype/t1tables.h (CID_FaceInfoRec): Change to unsignd `num_dicts`. * src/cid/cidparse.h (CID_Parser): Change to unsigned `num_dict`. * src/cid/cidgload.c (cid_load_glyph): Updated. * src/cid/cidload.c (cid_load_keyword, parse_fd_array, parse_expansion_factor, parse_font_name, cid_read_subrs, cid_face_open): Updated. * src/cid/cidobjs.c (cid_face_done): Updated. * src/cid/cidparse.c (cid_parser_new): Updated.

22befeef	2021-10-07T22:41:56	Signedness revisions. This eliminates explicit casting by switching to unsigned fields. The revisions mostly impact the handling of CID fonts. * include/freetype/fttypes.h (FT_Data): Change to unsigned `length`. * include/freetype/t1tables.h (CID_FaceDictRec): Ditto for `sd_bytes`. (CID_FaceInfoRec): Ditto for `gd_bytes` and `gd_bytes`. * include/freetype/internal/tttypes.h (TT_LoaderRec): Ditto for `byte_len`. * src/cid/cidgload.c (cid_load_glyph): Updated. * src/cid/cidload.h (cid_get_offset): Update argument. * src/cid/cidload.c (cid_get_offset, cid_read_subrs, cid_face_open): Updated. * src/cff/cffgload.c (cff_get_glyph_data, cff_free_glyph_data): Updated. * src/psaux/psft.c (cf2_getT1SeacComponent): Updated. * src/truetype/ttgload.c (TT_Process_Composite_Glyph, load_truetype_glyph): Updated.
842ec5ed	2021-10-07T00:46:14	meson.build (gen_docs): Use `current_source_dir` instead of `source_root`. These two are not equal when FreeType is used as a subproject, such as in `freetype-demos`. In that case, `source_root` points at the root project, causing the docs build to fail.
0f23ae2e	2021-10-05T16:28:40	* src/smooth/ftgrays.c (FT_DIV_MOD): Limit the ARM workaround.
a1560406	2021-10-05T14:19:06	[builds/unix, builds/vms] Standardize `mmap` failure. * builds/unix/ftsystem.c (FT_Stream_Open): Check for MAP_FAILED. * builds/vms/ftsystem.c (FT_Stream_Open): Ditto. This should cover https://savannah.nongnu.org/patch/?5909 as well.
467e49e8	2021-10-05T22:21:39	autogen.sh: Only copy submodules if building from a git branch. `autogen.sh` fails if building from a standard source tarball. Firstly, git expects to be called in a git repository, then `copy_submodule_files` blindly attempts to copy files. Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh` before compiling to regenerate build files. This patch ensures that various git commands are only called and 'dlg' files are only copied if `autogen.sh` is called from a git repository.

* meson.build: Optimize lookup for `python3` program. The python module's `find_installation` method is intended to provide routines for compiling and installing python modules into the `site-packages` directory. It does a couple of slow things, including run an introspection command to scrape sysconfig info from the detected interpreter, which are not needed for the sole use case of invoking the found installation as an executable. Furthermore, when invoked without the name or path of a python binary, it is hardcoded to always look for `python3` corresponding to the interpreter meson itself uses to run. So using `find_installation` did not even allow detecting `python2` as a fallback. Instead, switch to a simple `find_program` lookup that finishes as soon as the program is found.

* builds/meson/*.py: Fix name of python executable for auxiliary scripts. The previous change to check the return code of `run_command` invocations caused the CI to fail. Although most scripts used `python_exe` as the program command, the script to determine the project version did not. But, all scripts used `python` as the shebang, and this is not available on all systems. Particularly Debian does not provide a `python` command, though `python3` does exist. This meant that formerly the version number was lacking, and now the build simply fails. Instead, rely on `python3` since it is guaranteed to exist when running meson, and `python2` is end of life anyway.

2021-12-13T22:50:18

* meson.build: Check the return value of `run_command`. By default, errors are not checked and a command that is somehow broken will just capture incorrect output (likely an empty string). Current development versions of meson now raise a warning for this implicit behavior, and advise explicitly setting the `check:` keyword argumend to determine whether a failing return code should be considered an error. Since none of the commands in this project are expected to fail, mark them as required to succeed.

[truetype] Upstream the hdmx binary search. * src/truetype/ttobjs.h (TT_SizeRec): Add `widthp` for the hdmx widths. * src/truetype/ttobjs.c (tt_size_reset): Initialize `widthp` even though it might never be used by the interpreter. * src/truetype/ttgload.c (tt_loader_init): Avoid repeated searches in the hdmx table.

[truetype] Reset the IUP-called flags for each subglyph. This fixes fall-out from 7809007a5b88b15, where the composite accents were no longer hinted. * src/truetype/ttgload.c (ttloader_init): Move the IUP-called flag initialization from here... * src/truetype/ttinterp.c (TT_Run_Context): ... to here.

2021-12-11T22:54:06

[truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances.

2021-12-11T22:42:46

[truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable. This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY is specified by FT_Get_Advances and the `hdmx` data are located. Particularly, the classic v35 interpreter or "verified" ClearType fonts might see 100x speed up in retrieving the hdmx cache. * src/truetype/ttgload.c (TT_Load_Glyph): Insert the shortcut.

[truetype] Initialize the loader with `hdmx` data. The `hdmx` matching can be done before the glyph is loaded. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field. * src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx` code from here... (tt_loader_init): ... to here, before the glyph is loaded.

2021-12-11T22:22:57

[truetype] Relocate subpixel flag setting. `TT_RunIns` is too busy to deal with subpixel flags. It is better to set them in `tt_loader_init`, which is executed before each glyph program. * src/truetype/ttinterp.c (TT_RunIns): Move the flag setting from here... * src/truetype/ttgload.c (tt_loader_init): ... to here.

2021-12-11T22:12:25

[truetype] Limit INSTCTRL appication within specs. * src/truetype/ttinterp.c (Ins_INSTCTRL): Limit its global effects to the CVT program and local effects to the glyph program. This also fixes an Infinality buglet. The `ignore_x_mode` should be locally unset by the glyph program.

[bdf] Fix use of uninitialized value. In _bdf_readstream if the data contained no newline then the buffer would continue to grow and uninitialized data read until either the uninitialized data contained a newline or the buffer reached its maxiumum size. The assumption was that the line was always too long and the buffer had been filled, however this case can also happen when there is not enough data to fill the buffer. Correct this by properly setting the cursor to the end of the available data, which may be different from the end of the buffer. This may still result in one extra allocation, but only on malformed fonts. * src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove unread set of `avail`. Bug: https://lists.nongnu.org/archive/html/freetype-devel/2021-12/msg00001.html

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`.

[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. * src/type1/t1load.c (t1_allocate_blend): Zero initiailize.

[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. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261762 * src/type1/t1load.c (t1_allocate_blend): Remove early allocation and initialization. (parse_blend_design_positions, parse_weight_vector): Parse into local and assign to blend if valid. (T1_Open_Face): Check that if a blend exists that it has the weight vector and design positions.

[cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up. Reportd as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts into locals and update the vstore counts immediately after each entry becomes free-able.

[sfnt] Delay setting gasp ranges and count until computed. Previously, the gasp.numRanges was set and gasp.gaspRanges was allocated and assigned before a possible early exit if the frame could not be entered. It is also possible that the gaspRanges allocation could fail but the numRanges still be set to non-zero. In such cases an error would be returned, but the face would have a gasp in an inconsistent state which may still be accessed. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261450 * src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges and gasp.gaspRanges until after the ranges are initialized.

[sfnt] Delay setting names and langTags until computed. Previously, the table->names and table->langTags fields were created pointing to uninitialized memory and an early exit could happen if the frame could not be entered. The caller would then be unable to properly dispose of the memory as the string fields had not been initialized. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1261343 * src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags and table->names until after the memory they will point to is fully initialized.

Firstly, git expects to be called in a git repository, then `copy_submodule_files` blindly attempts to copy files. Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh` before compiling to regenerate build files. This patch ensures that various git commands are only called and 'dlg' files are only copied if `autogen.sh` is called from a git repository.
