0f35b042	2020-07-06T10:56:36	[build] Really fix multi and C++ builds. The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++. (FT_UNUSED): Define here instead of... * include/freetype/config/compiler-macros.h: ... here. (FT_FUNCTION_DECLARATION): Remove special definition for C++. (FT_LOCAL_ARRAY_DEF): Fix definition. * src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h, src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.
cb4a943b	2020-07-06T10:56:36	[build] Fix multi and C++ builds. The following builds were failing due to previous changes: make multi make multi CC="c++" * include/freetype/config/ftconfig.h: Remove `FT_END_HEADER'. * include/freetype/config/ftheader.h (FT_BEGIN_HEADER, FT_END_HEADER): Protect against redefinition. * src/cache/ftccache.h, src/cache/ftcmru.h, src/pcf/pcfutil.h, src/psaux/pserror.h, src/psaux/psft.h, src/psaux/psstack.h, src/sfnt/woff2tags.h: Include `compiler-macros.h'. * src/sfnt/woff2tags.c: Include `woff2tags.h'.
2eb8f886	2020-07-06T09:21:03	[psaux] Improve `t1_decoder_parse_metrics' (#58646). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function to handle `op_callsubr' and `op_return'.
b0667d2d	2020-07-02T11:20:10	[build] Improve visibility support of library function names. * include/freetype/config/public-macros.h (FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as public (and thus exportable). (FT_EXPORT): Use it. * include/freetype/config/compiler-macros.h (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as internal to the library (and thus hidden). Note that on ELF systems, all internal functions have hidden visibility, which avoids the need to enforce this when invoking the compiler (e.g., with an option like `-fvisibility=hidden'). (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros to deal with C and C++ linkage issues at the same time. (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, FT_BASE_CALLBACK_DEF): Redefined using new macros.
bb66c8d8	2020-07-02T11:09:57	[build] Split off more stuff from `ftconfig.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions required by the FreeType API headers to... * include/freetype/config/public-macros.h: ...this new file. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions used by the library but not to be exposed to clients to... * include/freetype/config/compiler-macros.h: ...this new file. * include/freetype/internal/*.h, src/raster/ftraster.h: Include `compiler-macros.h' where needed.
0322efb5	2020-07-02T10:31:28	[build] Move mac support code to `mac-support.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off mac-specific stuff to... * include/freetype/config/mac-support.h: ...this new file. * CMakeLists.txt, builds/unix/configure.raw: Remove `/undef -> #undef' string replacement; the affected code is no longer part of the `ftconfig.h' template.
bd7251ac	2020-07-02T10:24:20	[build] Put integer type definitions into `integer-types.h'. Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.
a4d92067	2020-07-02T10:10:25	[build] Rename `build/unix/ftconfig.in' to `ftconfig.h.in'. Since we are no longer limited to 8.3 file names, it is simpler to follow the usual conventions for template files. * builds/unix/ftconfig.in: Renamed to... * builds/unix/ftconfig.h.in: ...this. * CMakeLists.txt, builds/unix/configure.raw: Updated.
3bb512bc	2020-07-03T22:29:34	[smooth] Introduce direct oversampling for overlaps. This implements oversampling to metigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them.
19d39f43	2020-07-03T09:17:22	[smooth] Use direct rendering mode in Harmony. Instead of rendering 3 bitmaps side by side and reshuffling, we use direct rendering to deliver the bitmaps on each third byte. * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... (ft_smooth_lcd_spans): ... new span function.
2d67511a	2020-07-03T09:02:09	[smooth] Separate LCD paths from gray rendering. This makes `ft_smooth_render' a lot smaller and easier to follow. It also cleanly separates Harmony and ClearType-style LCD rendering algorithms. Now I only wish to move LCD filtering and geometry from FT_Library to FT_Renderer. * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here. [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's.
a4434747	2020-06-20T05:31:34	[cff] Fix handling of `style_name == NULL' (#58630). * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails by returning NULL in `cff_face_init', `remove_style' is still called. This means that the NULL pointer is dereferenced, causing a crash.
f594ffdc	2020-06-19T18:55:49	[cff] Fix another two memory leaks (#58629). * src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create' fails to allocate one of the `internal->subfont' variables, make sure to free `internal->topfont' and any successfully allocated subfonts.
2e2f3cb5	2020-06-19T16:29:07	[psaux] Fix memory leak (#58626). * src/psaux/psstack.c (cf2_stack_init): If `cf2_stack_init' fails to allocate the stack, return error early.
09b98060	2020-06-19T16:21:08	Fix memory leak (#58624). * src/base/ftobjs.c (FT_New_Size): Avoid trying to free `size->internal`, unless `size' has been allocated. This mistake appeared in the fix for 58611.
6e722f2e	2020-06-19T08:39:23	[base] Rework d1180b5f9598 until further notice. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Reject large outlines.
8ed5a247	2020-06-19T10:35:57	[cff, cid] Fix segfaults in case of error (#58621). * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c (cid_slot_done): If `ft_glyphslot_init' fails to allocate `internal', then the class' `done_slot' callback (called by `ft_glyphslot_done') must not dereference the pointer to `internal'.
d1180b5f	2020-06-19T08:18:26	[base] Fix UBSAN error. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23166 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Avoid values larger than 32 bits.
4d364b68	2020-06-19T05:41:37	[woff2] Fix segfault. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23402 * src/sfnt/sfwoff2.c (get_x_mins): Check whether `loca' table exists.
d924c5cf	2020-06-19T04:14:39	[sfnt] Support Intel compilers. * src/sfnt/pngshim.c (premultiply_data): Intel compilers do not currently support `__builtin_shuffle'.
a4429959	2020-06-18T15:12:03	[base] Fix memory leak (#58611). * src/base/ftobjs.c (FT_New_Size): When the call to `clazz->init_size' fails, make sure to free `size->internal'.
575b78d9	2020-06-18T15:12:03	[cff] Fix memory leak (#58610). * src/cff/cffobjs.c (cff_size_init): When the call to `funcs->create' fails, make sure to free `internal'.
74cebeae	2020-06-19T03:41:12	* src/cff/cffload.c (cff_index_get_pointers): Rename `t' to `tbl'.
c8cd139c	2020-06-18T13:46:37	[cff] Free table upon error allocating other data (#58609). * src/cff/cffload.c (cff_index_get_pointers): When new_bytes fails to allocate, make sure to free the table. Do the same for both allocations if there is a later error.
16586859	2020-06-13T21:15:45	Remove redundant inclusion of `ft2build.h'. * /: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
e1339133	2020-06-08T13:31:55	Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. /: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.
9e6e903c	2020-06-02T17:14:54	* src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps.
62fea391	2020-05-18T09:33:38	Remove obsolete HAVE_STDINT_H probing macro. This macro was updated by the unix configure script and the `CMakeLists.txt' one, but is never used in the source tree (nor is <stdint.h> included anywhere). * CMakeLists.txt, builds/unix/ftconfig.in: Don't handle `HAVE_STDINT_H'.
4eee1340	2020-05-18T09:16:12	Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.
3f70e6d2	2020-05-12T00:38:46	[smooth] Turn on LCD filtering during FreeType initialization. * src/smooth/ftsmooth.c (ft_smooth_init): Enable LCD filtering. * include/freetype/ftlcdfil.h: Document it, remove patent warnings. * include/freetype/freetype.h (FT_Render_Mode): Updated. * include/freetype/config/ftoption.h, devel/ftoption.h [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Do not mention patents.
652f8863	2020-05-11T23:30:37	[smooth] Stop using dedicated LCD modules and classes. The LCD modules were never truly independent. They mostly served as a way to disable patented LCD rendering, which is no longer necessary. The `smooth' module now handles LCD modes as well. * src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class. ft_smooth_lcdv_renderer_class): Deleted. (ft_render_smooth): Reworked from `ft_render_smooth_generic'. * src/smooth/ftsmooth.h: Remove dedicated LCD classes. * src/smooth/module.mk: Remove dedicated LCD modules. * include/freetype/config/ftmodule.h: Ditto. * builds/amiga/include/config/ftmodule.h: Ditto. * include/freetype/ftmodapi.h: Do not mention LCD modules.
132f19b7	2020-05-05T20:14:14	* Version 2.10.2 released. ========================== Tag sources with `VER-2-10-2'. * docs/VERSION.TXT: Add entry for version 2.10.2. * README, Jamfile (RefDoc), 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/2.10.1/2.10.2/, s/2101/2102/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 2. * builds/unix/configure.raw (version_info): Set to 23:2:17. * CMakeLists.txt (VERSION_PATCH): Set to 2. * docs/CHANGES: Updated.
a45da253	2020-05-08T10:59:37	* src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000.
de60e7d3	2020-05-03T17:11:20	* builds/freetype.mk: Refactor for readability.
49967cb6	2020-05-02T13:50:33	[builds] Clean up Windows CE project files. Remove version from filenames that caused a lot of polution in the release process. Use VERSIONINFO resource instead. * builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2008-ce/freetype.vcproj, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/freetype.dsp: s/2101//g, but add `ftver.rc'. * builds/wince/vc2008-ce/index.html, builds/wince/vc2005-ce/index.html, builds/windows/visualce/index.html: s/2101//g.
a612da0e	2020-05-01T22:52:52	* devel/ft2build.h: Override FT_CONFIG_MODULES_H here as well.
9c850f56	2020-05-01T22:30:15	[builds/unix] Consolidate marco overrides (for the demos to see them). * builds/unix/unix-cc.in (FT_CONFIG_MODULES_H, FT_CONFIG_OPTIONS_H): Override them here... * builds/freetype.mk: ... instead of here.
11beee85	2020-04-08T09:05:32	Allow setting `CC' in Unix build (#58051). * builds/unix/unix-cc.in (CC): Use `override'. The command line value of `CC' (if any) is stored already in `CCraw'.
7a019a63	2020-04-04T14:06:37	[woff2] Return if single stream operation fails. * src/sfnt/sfwoff2.c (get_x_mins): Do it. * src/sfnt/woff2tags.c: Remove unused include.
13c0df80	2020-03-22T23:29:51	[docs] Fix building docs if `srcdir' != `builddir'. `docs/reference/' was moved one directory up in commit 237fed6. builds/unix/unix-def.in (PIP): Remove variable. * configure: Create `docs' directory and copy assets from `docs/markdown'. * docs/README: Output directory is `reference'.
1fd31487	2020-03-21T20:17:17	[docwriter] Drop support for Python < 3.5. Python versions < 3.5 have reached end-of-life and as such, no security or bug fixes will be provided for those versions. See https://devguide.python.org/#status-of-python-branches for more information. * Jamfile (RefDoc): Add `site' parameter. * builds/detect.mk (std_setup): Update Python version requirement. * builds/freetype.mk (refdoc-venv): Use pip as `python -m pip'. * builds/unix/ax_compare_version.m4, builds/unix/ax_prog_python_version.m4: Macros to detect Python version. New files. * builds/unix/configure.raw: Check for Python >= 3.5 and remove check for `pip'. * docs/CHANGES, docs/INSTALL.GNU, docs/README: Updated.
6a431038	2020-03-02T18:21:27	[gzip] Support `gzip' encoded header conditionally. In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used. Problem report in https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to `inflateInit2' depending on whether the system installation is being used or the internal copy.
11975fe9	2020-02-29T20:18:00	Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure.
149b9055	2020-02-29T20:28:03	ChangeLog entry for last commit.
216e0776	2020-02-28T07:43:00	[truetype] Add better checks for loading `gvar' table (#57905). * src/truetype/ttgxvar.c (ft_var_load_gvar): Delay settings of any `blend->xxxcount' values until the corresponding data has been checked. Also do some sanitizing to avoid a too early exit. (TT_Vary_Apply_Glyph_Deltas): Improve tracing message.
141da028	2020-02-27T09:49:06	Make `FT_HAS_' and `FT_IS_' really return true (#57906). * include/freetype/freetype.h (FT_HAS_, FT_IS_): Implement it.
5b1a37af	2020-02-25T11:08:11	Fix for CFF space glyph regression (#57541). * src/psaux/psft.c (cf2_decoder_parse_substrings): Replace early-out with FT_OFFSET.
fa147af4	2020-02-22T18:30:46	[woff2] Fix font table access. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=20778 * src/sfnt/sfwoff2.c (get_x_mins): Explicitly check for presence of `head' table, which might not have been processed yet.
6e49dff0	2020-02-21T20:57:52	[psaux] Make `t1_decoder_parse_metrics' handle `op_div' (#57519). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function.
49f3394d	2020-02-19T12:56:49	[autofit] Add support for Hanifi Rohingya script. * src/autofit/afblue.dat: Add blue zone data for Hanifi Rohingya. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Hanifi Rohingya standard character. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Hanifi Rohingya data.
84d56589	2020-02-19T18:13:02	Require HarfBuzz 1.8. * builds/unix/configure.raw, CMakeLists.txt: Request HarfBuzz 1.8.0 or newer. We are going to add auto-hinter support for Hanifi Rohingya, which was introduced in Unicode 11.0.
8930cc96	2020-02-12T18:25:03	* src/sfnt/ttcmap.c (tt_face_build_cmaps): Ignore version (#57708).
4a19a53d	2020-02-04T13:37:19	* src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#57732). The font that exceeds the old limit is Constantine, version 1.001.
e5038be7	2020-01-19T17:05:19	Update all copyright notices.
fd03cf88	2020-01-04T19:28:36	[base] Fix `FREETYPE_PROPERTIES=type1:hinting-engine=adobe`. * src/base/ftpsprop.c (ps_property_set) [hinting-engine]: Avoid an incorrect return value that caused a warning. The function did the right thing, though.
50b01387	2020-01-04T18:42:27	Add reference to another oss-fuzz bug report.
a99a8e28	2020-01-03T18:09:12	[woff2] Fix memory leaks and a runtime warning. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=19773 * src/sfnt/sfwoff2.c (compute_ULong_sum): Add missing cast. (reconstruct_hmtx): Add missing deallocation calls.

a4df0373	2019-12-31T16:04:01	[woff2] Allow bitmap-only fonts (#57394). * src/sfnt/sfwoff2.c (reconstruct_font): Fix test for `glyf' and `loca' tables.
496601e5	2019-12-18T23:11:22	[docs] (2/2) Fix generation of API documentation (#56745). Creating the API Reference in the (new) `reference' sub-directory is consistent with other documentation sub-topics, such as `design', `glyphs' and `tutorial'. This patch fixes broken hyperlinks in the documentation pointing to and from the API Reference. It also allows web assets to load from their relative paths. * builds/freetype.mk (DOC_DIR): Adjust. (refdoc, refdoc-venv): Add `--site' argument. * builds/toplevel.mk (do-dist): Updated.
237fed6d	2019-12-18T23:07:35	[docs] (1/2) Move static web assets (#56745). * docs/reference/: Move ... docs: ... one directory up.

[build] Really fix multi and C++ builds. The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++.

[build] Improve visibility support of library function names. * include/freetype/config/public-macros.h (FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as public (and thus exportable). (FT_EXPORT): Use it. * include/freetype/config/compiler-macros.h (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as internal to the library (and thus hidden). Note that on ELF systems, all internal functions have hidden visibility, which avoids the need to enforce this when invoking the compiler (e.g., with an option like `-fvisibility=hidden'). (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros to deal with C and C++ linkage issues at the same time. (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF, FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK, FT_BASE_CALLBACK_DEF): Redefined using new macros.

[smooth] Introduce direct oversampling for overlaps. This implements oversampling to metigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to...

[gzip] Support `gzip' encoded header conditionally. In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used. Problem report in https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to `inflateInit2' depending on whether the system installation is being used or the internal copy.

Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure.
