Alexei Podtelezhnikov 7f7bf6f0 2022-01-14T20:33:28 * include/freetype/internal/compiler-macros.h [FT_COMPARE_DEF]: Tighten. This works around Watcom C library using __watcall.
Alexei Podtelezhnikov 7eb9a9db 2022-01-14T14:40:11 * src/pshinter/pshglob.c (psh_globals_new): Avoid zeroing. This large allocation is followed by careful initialization. Whatever is missed should be initialized manually.
Alexei Podtelezhnikov 81b81feb 2022-01-14T18:22:23 * src/base/fthash.c (hash_insert): Avoid unnecessary zeroing.
Alexei Podtelezhnikov 904ad212 2022-01-13T23:38:56 * src/bdf/bdflib.c (_bdf_parse_glyphs): Remove redundant assignment.
Alexei Podtelezhnikov ee52b571 2022-01-13T09:45:48 * src/lzw/ftlzw.c (FT_Stream_OpenLZW): Avoid unnecessary zeroing.
Ben Wagner 6ee89519 2022-01-12T15:12:53 [bzip2] Reset bzip stream on any error. According to the bzip documentation it is undefined what will happen if `BZ2_bzDecompress` is called on a `bz_stream` it has previously returned an error against. If `BZ2_bzDecompress` returns anything other than `BZ_OK` the only valid next action is `BZ2_bzDecompressEnd`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43564 * src/bzip2/ftbzip2.c (FT_BZip2FileRec_): Add `reset` to track the need to reset the stream. (ft_bzip2_file_init): Initialize `reset` to 0. (ft_bzip2_file_reset): Set `reset` to 0 after resetting. (ft_bzip2_file_fill_output): Set `reset` to 1 when `BZ2_bzDecompress` returns anything other than `BZ_OK`.
Azamat H. Hackimov ca44a236 2022-01-12T04:26:39 .gitlab-ci.yml: Add steps to `before_script` to ensure recent CA. Fetch current list of valid CAs from Windows Update and manually import them to trusted datastore. This action is required to make downloads work from sites that need recent Let's Encrypt ISRG Root X1 certificate.
Werner Lemberg b647dbde 2022-01-12T06:21:52 .gitlab-ci.yml: Minor comment cleanups.
Ben Wagner f1d3b9f1 2022-01-11T17:15:35 Revert "[bzip2] Avoid use of uninitialized memory." This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6. The original commit did avoid the use of uninitialized memory. However, it appears that the original commit is no longer required. The underlying issue was resolved by a change in freetype2-testing "Build bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so bzip2 writes were not tracked or considered initialized. Clearing `buffer` in the original commit allowed msan to see the `buffer` content initialized once in FreeType code, but msan saw no writes into buffer from bzip2. With bzip2 now built with msan, the bzip2 writes are properly instrumented and msan sees the bzip2 writes into the buffer. As a result the original commit can be safely reverted to allow for better detection of other uninitialized data scenarios. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`. [0] https://github.com/freetype/freetype2-testing/commit/3c052a837a3c960709227a0d6ddd256e87b88853
Ben Wagner e838c37c 2022-01-11T11:14:32 [type42] Track how much type42 ttf data is available. Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header data which it expects `t42_parse_sfnts` to fill out from /sfnts data. However, there is no guarantee that `t42_parse_sfnts` will actually be called while parsing the type42 data as the /sfnts array may be missing or very short. This is also confusing behavior as it means `T42_Open_Face` is tightly coupled to the implementation of the very distant `t42_parse_sfnts` code which requires at least 12 bytes to already be reserved in `face->ttf_data`. `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how much space is reserved for ttf data instead of traking how much data has actually been written into `face->ttf_data`. It will also act strangely in the presense of multiple /sfnts arrays. * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized to NULL. Free `ttf_data` on error. * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and set it to the actual number of bytes read. Ensure `ttf_data` is freed if there are multiple /sfnts arrays or there are any errors.
Dominik Röttsches 3876846e 2022-01-11T13:40:20 [sfnt] Fix limit checks for `COLR` v1 ClipBoxes * src/sfnt/ttcolr.c (tt_face_get_color_glyph_clipbox): Fix off-by-one in limit checks.
Werner Lemberg d0cfb4e1 2022-01-11T10:54:10 Update all copyright notices.
Werner Lemberg 947fddc8 2022-01-09T07:26:26 * src/sfnt/ttcolr.c (read_paint): Fix undefined left-shift operation. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43151
Werner Lemberg 639a0215 2022-01-11T09:14:48 * src/type42/t42objs.c (T42_Open_Face): Avoid use of uninitialized memory. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43508
Werner Lemberg 33626164 2022-01-11T08:01:30 .gitlab-ci.yml: Fix typo in previous commit.
Werner Lemberg 4c0db607 2022-01-11T07:52:28 .gitlab-ci.yml: Update Windows image. The old image produced errors like ``` Downloading zlib patch from https://wrapdb.mesonbuild.com/v2/zlib_1.2.11-5/get_patch A fallback URL could be specified using patch_fallback_url key in the wrap file WrapDB connection failed to https://wrapdb.mesonbuild.com/v2/zlib_1.2.11-5/get_patch with error <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1122)> ```
Werner Lemberg 2e62b744 2022-01-11T05:37:56 * subprojects/zlib.wrap: Update from upstream.
Werner Lemberg 4a89112b 2022-01-08T16:56:57 * src/sfnt/ttcolr.c (tt_face_get_color_glyph_clipbox): Add limit checks. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40716
Werner Lemberg 3f9b78fc 2022-01-10T18:19:41 [zlib] Don't typedef `ptrdiff_t`. While using zlib in 'solo' mode (via the `Z_SOLO` macro), we actually include some standard header files, making the typedef fail on systems where the native `ptrdiff_t` type differs. Fixes #1124. * src/zlib/zutil.h: Comment out definition; it doesn't work on Windows. * src/zlib/patches/freetype-zlib.diff: Updated.
Werner Lemberg da8a8b8b 2022-01-10T17:25:47 [zlib] Some organizational changes. We now first apply zlib's `zlib2ansi` script, then FreeType's patch file. * src/gzip/README.freetype: Updated. * patches/0001-zlib-Fix-zlib-sources-to-compile-for-FreeType.patch: Renamed to... * patches/freetype-zlib.diff: This. Clean up description, then regenerate it as follows: - Copy unmodified files from `zlib` repository. - Run `zlib2ansi` script. - Run `git diff -R > patches/freetype-zlib.diff.new`. - Insert patch description of old diff file, then replace old diff with new diff file.
David Turner a25e85ed 2021-08-17T15:20:25 [gzip] Update sources to zlib 1.2.11 This can be tested by building with the Unix development build make setup devel make or by building the freetype-demos programs with meson setup build -Dfreetype2:zlib=internal meson compile -C out and trying to run `ftview` with a `.pcf.gz` font file. * src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also remove the temporary fix introduced in commit 6a431038 to work around the fact that the internal sources were too old. * src/gzip/README.freetype: New file describing the origin of the sources and how they were modified. * src/gzip/patches/*: Patch files applied to original sources. * src/gzip/*: Updated zlib sources with the patch file(s) from `src/gzip/patches/` applied, followed by a conversion with zlib's `zlib2ansi` script.
David Turner 0d343863 2021-08-17T17:27:36 [meson] Change Zlib configuration option. * meson_options.txt, meson.build: Change the format of the 'zlib' meson build configuration option to be a combo with the following choices: - none: Do not support gzip-compressed streams at all. - internal: Support gzip-compressed streams using the copy of the gzip sources under `src/gzip/`; this should only be used during development to ensure these work properly. - external: Support gzip-compressed streams using the 'zlib' Meson subproject, linked as a static library. - system: Support gzip-compressed streams using a system-installed version of zlib. - auto: Support gzip-compressed streams using a system-installed version of zlib, if available, or using the 'zlib' subproject otherwise. This is the default. - disabled: Backward-compatible alias for 'none'. - enabled: Backward-compatible alias for 'auto'.
Werner Lemberg d276bcb7 2022-01-09T07:48:59 [bzip2] Avoid use of uninitialized memory. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Don't use `FT_QNEW` but `FT_NEW` for setting up `zip` to avoid uninitialized memory access while handling malformed PCF fonts later on. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42800
Alexei Podtelezhnikov ca011128 2022-01-08T22:28:44 [sfnt] Fix off-by-one error. The 0-base index is equal to the number of previosly parsed entries. It is an error to adjust it by one to get the number truncated by a stream error. This is probably inconsequential because valid entries are correctly accounted for. * src/sfnt/ttload.c (check_table_dir): Do not adjust the truncated number of tables.
Werner Lemberg 7a493e3a 2022-01-08T10:28:19 [sfnt, type42] Correct previous commit. Really fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42773. * src/sfnt/ttload.c (check_table_dir): Revert change. * src/type42/t42.parse.c (t42_parse_sfnts): Don't use `FT_QREALLOC` but `FT_REALLOC` for setting up `ttf_data` to avoid uninitialized memory access while handling malformed TrueType fonts later on.
Werner Lemberg bf9b1ef9 2022-01-07T10:25:52 * src/sfnt/ttload.c (check_table_dir): Initialize `table`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42773
Werner Lemberg b5c2172f 2022-01-07T06:53:44 [sfnt] Avoid 'runtime error: applying zero offset to null pointer'. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_byte_aligned): Exit early if `line` is NULL.
Werner Lemberg 5aa2a5c3 2022-01-07T06:41:36 [autofit, pshinter] Use `FT_OFFSET`. This avoids ``` runtime error: applying zero offset to null pointer ``` warnings of clang's undefined behaviour sanitizer. * src/autofit/afcjk.c (af_cjk_hints_link_segments, af_cjk_hints_compute_edges, af_cjk_hints_compute_blue_edges, af_cjk_hint_edges, af_cjk_align_edge_points): Do it. * src/autofit/afhints.c (af_glyph_hints_align_edge_points, af_glyph_hints_align_strong_points): Ditto. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hints_link_segments, af_latin_hints_compute_edges, af_latin_hints_compute_blue_edges, af_latin_hint_edges): Ditto. * src/pshinter/pshalgo.c (psh_hint_table_init): Ditto.
Ben Wagner afb4ca01 2022-01-06T12:54:15 [truetype] Reset localpoints when varying cvt. When iterating over the cvt tuples and reading in the points it is necessary to set all of `localpoints`, `points`, and `point_count` in all cases. The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid. Fixes: https://crbug.com/1284742
Werner Lemberg 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.
Alexander Borsuk 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.
Alexander Borsuk 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.
Eli Schwartz 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.
Eli Schwartz 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.
Eli Schwartz 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Ben Wagner 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
Alexei Podtelezhnikov 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`.
Cameron Cawley 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.
Cameron Cawley 9a533aa2 2021-12-06T21:46:47 * builds/windows/visualc/freetype.vcproj: Add missing file.
Werner Lemberg 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.

Seigo Nonaka 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).
Alexei Podtelezhnikov 64e26ad3 2021-11-27T22:31:17 * builds/windows/vc2010/freetype.vcxproj (DlgCopy): Minor tweak.

Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 99086bf2 2021-11-23T16:02:02 * builds/windows/vc2010/freetype.vcxproj (DlgCopy): Use transforms.

Werner Lemberg 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.

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.
Werner Lemberg 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.
Werner Lemberg 238245cd 2021-11-16T22:07:28 Fix clang++ warnings. * src/*: Initialize some variables to NULL.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Dominik Röttsches 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
Alexei Podtelezhnikov 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`.
Alexei Podtelezhnikov 42e61723 2021-11-11T23:06:36 Explicitly define `FT_MSB` for Clang. * include/freetype/internal/ftcalc.h [__clang__] (FT_MSB): Updated.
Alexei Podtelezhnikov c5cd2a3d 2021-11-10T08:46:26 * src/truetype/ttgxvar.c (ft_var_to_normalized): Edge optimization.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Werner Lemberg d899b200 2021-11-08T12:27:04 * src/sfnt/sfobjs.c (sfnt_open_font): Fix typo.
Werner Lemberg b86f96bc 2021-11-08T11:15:50 * src/gxvalid.*, src/otvalid.*: Fix `-Wformat` warnings.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Alexei Podtelezhnikov 9ebdc9cb 2021-11-07T23:21:40 * src/sfnt/ttload.c (tt_face_load_gasp): Fix a type mismatch warning.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Jany Belluz 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.
Jany Belluz 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.
Jany Belluz 23d1d8ad 2021-11-04T08:55:39 * src/truetype/ttgxvar.c: Fix typos in macros that guard CVAR code.
Alexei Podtelezhnikov 5d651faa 2021-11-03T22:43:22 * docs/INSTALL: Mention Meson and MSBuild more prominently.
Gabor Kertesz 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.
Dominik Röttsches 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
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 94cb3a2e 2021-10-29T10:31:59 * src/truetype/ttgload.c (load_truetype_glyph): Fix MSVC warning C4312.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Werner Lemberg 80b13f57 2021-10-26T10:57:17 Formatting.
Ben Wagner 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 92f5e15f 2021-10-23T09:43:46 * builds/windows/vc2010/freetype.vcxproj: Use MachineARM64.
Alexei Podtelezhnikov 5e6efd6a 2021-10-22T15:25:10 [builds/windows] Prioritize x64. * builds/windows/vc2010/freetype.sln: Sort entries.
