* builds/unix/ftconfig.h.in [FT_USE_AUTOCONF_SIZEOF_TYPES]: Removed.
* builds/unix/configure.raw: Remove AC_CHECK_SIZEOF and update.
After this commit, autoconf builds will fully rely on <limits.h>
rather than falling back on it if AC_CHECK_SIZEOF failed for some
reason. There is a risk that misconfigured cross-compilation might
have wrong headers. Note that Meson and CMake builds always relied on
<limits.h> for sizes and availability of integer types.
Signed 24-bit values are extremely rare. FreeType only reads them in
PFR fonts with bitmap strikes conditionally. They have not been seen
in the known fonts. That is why this bug could never be discovered.
`FT_FRAME_OFF3` propagates sign correctly.
* include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE):
Propagate sign into 32-bit value.
(FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused.
BDF comments are neither actually collected nor retrieved. There is
no need to be fancy with delimiters.
* src/bdf/bdflib.c (_add_bdf_comment): Delimit comments with zeros...
(bdf_load_font): ...and do not null-terminate comments additionally.
(_bdf_parse_glyphs): Check if comments are kept, which they are not.
(_bdf_parse_start): Minor clean up.
* src/pcf/pcfread.c (pcf_load_font): Do not call `FT_MulDiv` for a
small job.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Ditto.
* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a comment.
With Windows memory management tracking heap, it is important to use
it during the stream opening fallback. In Unix, the argument is
unused, but it is better to set it correctly.
* src/base/ftobjs.c (FT_Stream_New): Set memory before calling
`FT_Stream_Open`.
* builds/windows/ftsystem.c, builds/unix/ftsystem.c (FT_Stream_Open,
ft_close_stream_by_free): Call `ft_alloc` and `ft_free` with proper
memory argumment.
Calling `CreateFileW` without making sure that the patname is really
`wchar_t` is a bad idea and can lead to unpredictable overreads. For
Windows CE, we impelemnt the missing API.
Fixes#1098 and !76 again.
* builds/windows/ftsystem.c (FT_Stream_Open): Call `CreateFileA`.
[_WIN32_WCE] (CreateFileA, FileSizeEx): Implement missing interfaces.
Windows handles wchar_t* UTF-16 and char* ANSI (presently UTF-8)
filenames using alternative -A and -W API. We'll try them both
when opening a file. This means that you should not worry about
about conversions.
Fixes#1098 and !76.
* builds/windows/ftsystem.c (FT_Stream_Open): Call alternative
`CreateFile` in the case of failure.
Loops with unsigned decrement can be reliably stopped when the counter
wraps around after reaching zero.
* src/cff/cffload.c (cff_charset_compute_cids): Use unsigned counter.
* src/pshinter/pshalgo.c (psh_hint_table_activate_mask): Ditto.
* src/pshinter/pshrec.c (ps_mask_table_merge): Ditto.
* src/base/ftdbgmem.c (FT_DumpMemory): Check for active debugger.
(ft_mem_table_destroy): Move `FT_DumpMemory` call from here...
(ft_mem_debug_done): ... to here.
These changes are neccessary to properly recover `memory->user` that
holds the Windows heap handle now.
* src/base/ftdbgmem.c (ft_mem_debug_init): Handle all table allocations,
initializations, and sizing instead of...
(ft_mem_table_new): ... this function removed.
(ft_mem_debug_done): Better check for the active debugger and free the
debugger table here instead of...
(ft_mem_table_destroy): ... here.
* src/base/ftstream.c (FT_Stream_ReadUShort, FT_Stream_ReadUOffset,
FT_Stream_ReadULong and their LE variants): Remove unnecessary
initialization and slightly refactor.
(FT_Stream_GetByte, FT_Stream_ReadByte): Rename to return unsigned
value and align with sister functions.
* include/freetype/internal/ftstream.h (FT_Stream_GetByte,
FT_Stream_ReadByte): Update prototypes and caller macros.
