2022-05-01 Werner Lemberg <[email protected]>
* Version 2.12.1 released.
==========================
Tag sources with `VER-2-12-1'.
* docs/VERSION.TXT: Add entry for version 2.12.1.
* 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/2.12.0/2.12.1/, s/2120/2121/.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
* builds/unix/configure.raw (version_info): Set to 24:3:18.
* CMakeLists.txt (VERSION_PATCH): Set to 1.
2022-04-30 Anuj Verma <[email protected]>
[sdf] Do not throw errors for invisible glyphs.
* src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Return `FT_Err_Ok` if
width or height is zero, since some glyphs do not generate visible bitmaps.
Fixes #1150.
2022-04-30 Werner Lemberg <[email protected]>
* src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_COLOR` for SVG fonts.
Fixes #1151.
2022-04-27 Brendan Shanks <[email protected]>
autogen.sh: Fix building when freetype is itself a git submodule.
There are situations where .git is not a directory, like when
freetype is a submodule in another repository.
2022-04-26 Alexei Podtelezhnikov <[email protected]>
[builds/windows] Simplify non-desktop UWP check.
Fixes mingw compilation described in !159.
* builds/windows/ftsystem.c: Do not use WINAPI_FAMILY_PARTITION macro.
2022-04-25 Alexei Podtelezhnikov <[email protected]>
[truetype] Reset IUP flags in `TT_RunIns`.
Fixes #1148 by moving the flag initialization back, partly reverting
7809007a and fd03dcc1. Initializing these flags elsewhere skips 'cvt'.
* src/truetype/ttinterp.c (TT_RunIns): Initialize the IUP flag here...
(TT_Run_Context): ... instead of here.
2022-04-24 Xavier Claessens <[email protected]>
[meson] Remove `default_library=both` from `default_options`.
It is inconsistent with what all other Meson projects do.
It also prevents static linking to FreeType when it is a subproject because
`default_options` in a subproject takes precedence on values set on the main
project. For example, building 'GStreamer' with `-Ddefault_library=static`
would still dynamically link on FreeType unless the user also sets
`-Dfreetype2:default_library=static`.
* meson.build: Updated.
* .gitlab-ci.yml: Retain `both` option for testing.
2022-04-19 Werner Lemberg <[email protected]>
* src/truetype/ttgload.c (TT_Process_Simple_Glyph): Integer overflow.
Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=46792
2022-04-16 Georg Brandl <[email protected]>
* src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_SVG]: Fix segfault.
This can happen if the function is called with `size` being `NULL`.
Fixes #1147.
2022-04-14 Steve Lhomme <[email protected]>
.gitlab-ci.yml: Add a Universal Windows build target
It's compiled for Windows 10 and up, ensuring UNICODE is set (default for UWP)
and selecting the proper WINAPI_FAMILY (WINAPI_FAMILY_APP).
Do not try to run the UWP exe in the Docker as it doesn't work.
2022-04-04 Ben Wagner <[email protected]>
[sfnt] Correct FT_ColorStopIterator documentation.
* include/freetype/ftcolor.h (FT_ColorStopIterator): the user should not
set `p` to NULL before calling `FT_Get_Colorline_Stops`. `p` and
`num_color_stops` are set by `FT_Get_Paint`. `p` and
`current_color_stop` are updated by `FT_Get_Colorline_Stops`.
2022-04-01 Werner Lemberg <[email protected]>
* builds/unix/configure.raw: Add option `--with-librsvg`.
Since 'librsvg' is written in Rust, this option allows distributions to
avoid a dependency on the entire Rust toolchain to provide the FreeType demo
programs.
Suggested by Lars Wendler in !156.
2022-04-01 Werner Lemberg <[email protected]>
* src/sfnt/sfwoff.c (reconstruct_glyf): Fix gcc 10 warning.
2022-04-01 Werner Lemberg <[email protected]>
[gzip] Update sources to zlib 1.2.12.
2022-04-01 Eric Jing <@CPUcontrol>
CMakeLists.txt: Fix `Info.plist` path.
When building a framework using CMake with `add_subdirectory`, CMake must be
able to find `freetype-Info.plist` when configuring the framework
properties.
Fixes #1145.
2022-04-01 Werner Lemberg <[email protected]>
Whitespace.
2022-04-01 Ben Wagner <[email protected]>
[truetype] Use SUB_LONG for component offset.
* src/truetype/ttgload.c (TT_Process_Composite_Component): do it.
Bug: https://crbug.com/1309429
2022-03-31 Werner Lemberg <[email protected]>
CMakeList.txt: Update code to handle recent changes for `freetype.pc`.
Fixes #1144.
2022-03-31 Werner Lemberg <[email protected]>
CMakeLists.txt: s/PKG_CONFIG/PKGCONFIG/, s/REQUIRED_/REQUIRES_/.
2022-03-31 Werner Lemberg <[email protected]>

docs/freetype-config.1: s/2.11.1/2.12.0/, s/2111/2120/.
* include/freetype/freetype.h (FREETYPE_MINOR): Set to 12.

since version 2.11.0 (when we stopped creating this file manually).
2022-03-31 Werner Lemberg <[email protected]>
Fix clang++ warnings.
* src/base/ftglyph.c (ft_svg_glyph_prepare), src/base/ftobj.c

[sfnt] Fix bounds check in SVG.
The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not
protected by parentheses. As a result, the expression
`table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to
`table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected
`table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect
bounds check which may lead to reading past the end of the `SVG ` table.
* src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in
parentheses.
Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=45179
2022-02-23 Ben Wagner <[email protected]>
[psaux] Full bounds check for OtherSubr 19.
It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is
NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with
`blend->num_designs` set to 2, and the user supplied `idx` to be large (for
example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds
check overflows in a well defined manner, allowing for an invalid call to
`memcpy`.
In addition, it is possible to call OtherSubr 19 with
`decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying
that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes
the bounds check (it is logically always fine to copy nothing starting at
index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed
by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is
undefined behavior (even if `count` is zero).
* src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that
`blend->num_designs` can be copied to `decoder->buildchar[idx]`.
Also avoid passing NULL to `ft_memcpy`.

[pshinter] Avoid unnecessary zeroing.
* src/pshinter/pshalgo.c (psh_hint_table_init,psh_glyph_init,
psh_glyph_interpolate_normal_points): Use FT_QNEW_ARRAY.

* include/freetype/freetype.h: Clarify `FT_Size` life cycle.

[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.
2022-01-18 Alexei Podtelezhnikov <[email protected]>
* 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.

[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`.

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.

[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`.

[cache] Avoid unnecessary zeroing.
* src/cache/ftccmap.c (ftc_cmap_node_new): Use `FT_QNEW`.
* src/cache/ftcimage.c (FTC_INode_New): Ditto.
* src/cache/ftcsbits.c (FTC_SNode_New): Ditto.

Add Watcom C/C++ support.
* include/freetype/config/integer-types.h: Make sure `long long` is
used then available.
* include/freetype/internal/ftcalc.h (FT_MSB): Add Watcom C/C++ pragma.
2022-01-15 Alexei Podtelezhnikov <[email protected]>
* src/sdf/ftbsdf.c (ED): s/near/prox/.
This works around the Watcom C definition of `near` as restricted
__near.
2022-01-15 Alexei Podtelezhnikov <[email protected]>
* include/freetype/internal/compiler-macros.h [FT_COMPARE_DEF]: Tighten.
This works around Watcom C library using __watcall.
2022-01-14 Alexei Podtelezhnikov <[email protected]>
* src/pshinter/pshglob.c (psh_globals_new): Avoid zeroing.
This large allocation is followed by careful initialization. Whatever
