|
054782c4 | 2022-01-19 22:14:06 | [base] Undefined scale means no scale. It might be surprising that FreeType does not have default ppem and the size has to be set explicitly or face undefined behavior with undefined variables and errors. This offers an alternative to missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined behavior is bettr than undefined one. This is alternative to !132 and discussed in https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708 * src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale. * include/freetype/freetype.h: Document it. | |
|
773e31c7 | 2022-01-18 14:05:46 | * src/autofit/afglobal.c (af_face_globals_new): Reduce zeroing. Everything in AF_FaceGlobals is initialized except metrics. Those are zeroed here and initialized on demand later. | |
|
d118bf8e | 2022-01-15 23:09:53 | [bdf,type1] Avoid unnecessary hash zeroing. * src/bdf/bdflib.c (_bdf_parse_start): Use `FT_QALLOC`. * src/type1/t1load.c (parse_subrs): Use `FT_QNEW`. | |
 |
3f6497bd | 2022-01-15 22:44:28 | Add Watcom C/C++ calling. In the unlikely case the source is built with OpenWatcom's -ec? switches to enforce a calling convention, the qsort() compare function must still be set to __watcall. * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): Updated. | |
|
5e227133 | 2022-01-15 17:08:18 | [pshinter] Avoid accessing uninitialized zone. The `normal_top.count` may be 0, implying no `normal_top.zones` exist. The code must not access these (non-existent) `normal_top.zones`. * src/pshinter/pshalgo.c (ps_hints_apply): Do not assume that `normal_top.zones[0]` is initialized. Test `normal_top.count` before using `normal_top.zones[0]`. Do not rescale if there are no `zones`. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43675 | |

|
ba5d661f | 2022-01-14 21:54:17 | * src/sdf/ftbsdf.c (ED): s/near/prox/. This works around the Watcom C definition of `near` as restricted __near. | |
|
7f7bf6f0 | 2022-01-14 20:33:28 | * include/freetype/internal/compiler-macros.h [FT_COMPARE_DEF]: Tighten. This works around Watcom C library using __watcall. | |
|
7eb9a9db | 2022-01-14 14:40:11 | * src/pshinter/pshglob.c (psh_globals_new): Avoid zeroing. This large allocation is followed by careful initialization. Whatever is missed should be initialized manually. | |

6ee89519 | 2022-01-12 15:12:53 | [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`. | |

f1d3b9f1 | 2022-01-11 17:15:35 | 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 | |

e838c37c | 2022-01-11 11:14:32 | [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. | |

3f9b78fc | 2022-01-10 18:19:41 | [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. | |
|
da8a8b8b | 2022-01-10 17:25:47 | [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. | |

a25e85ed | 2021-08-17 15:20:25 | [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. | |
|
0d343863 | 2021-08-17 17:27:36 | [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'. | |

d276bcb7 | 2022-01-09 07:48:59 | [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 | |
|
ca011128 | 2022-01-08 22:28:44 | [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. | |
|
7a493e3a | 2022-01-08 10:28:19 | [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. | |

afb4ca01 | 2022-01-06 12:54:15 | [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 | |
|
2b672e72 | 2022-01-02 18:33:03 | * builds/unix/configure.raw: Restore `SYSTEM_ZLIB` variable. This was accidentally removed with commit 93ebcbd0 almost eight years ago. | |

 |
d6a5c577 | 2021-12-13 23:40:16 | * 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 | 2021-12-13 23:33:03 | * 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 | 2021-12-13 22:50:18 | * 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 | 2021-12-13 11:44:24 | [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 | 2021-12-12 12:29:04 | [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 | 2021-12-11 22:54:06 | [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 | 2021-12-11 22:42:46 | [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 | 2021-12-11 22:34:27 | [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 | 2021-12-11 22:22:57 | [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 | 2021-12-11 22:12:25 | [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 | 2021-12-09 17:06:28 | [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 | 2021-12-07 10:19:06 | [truetype] Reduce Infinality footprint again. * src/truetype/ttgload.c (compute_glyph_metrics): Streamline and prioritize the Infinality checks to use `hdmx`. | |
 |
1f951898 | 2021-12-06 23:08:46 | [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. | |

 |
3b45f564 | 2021-11-29 18:17:49 | * 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). | |

9079c5d9 | 2021-11-13 08:53:19 | 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`.
