Instead run a closure on the retained charstrings and copy only the referenced subrs. This significantly speeds up cases with small character sets.

Behdad Esfahbod 404cb99d86 [buffer-diff] Fix check for glyph flag equality
I'm not sure if the old behavior was intentional, but it was checking
that the glyph flags were a subset of the reference buffer's glyph
flags.  I don't see why that is useful.  Fix that.

Then make the buffer-verify code ignore flag differences when verifying
buffers, since our unsafe-to-concat flag at least, is conservative and
not guaranteed to be produced the same in fragments.  See:

Martin Storsjö d88269c827 freetype: Fix function signatures to match without casts
Clang 16 has got a new stricter warning for casts of function types
(see 1aad641c79).

This new warning gets included as part of the existing error
diagnostic setting of -Wcast-function-type.

This fixes errors like these:

../src/hb-ft.cc:1011:34: error: cast from 'void (*)(FT_Face)' (aka 'void (*)(FT_FaceRec_ *)') to 'FT_Generic_Finalizer' (aka 'void (*)(void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
    ft_face->generic.finalizer = (FT_Generic_Finalizer) hb_ft_face_finalize;

2022-10-26 22:34:02 +02:00
Marco Rebhan db292f6f02
Pass through absolute paths to cmake config directly
The previous code concatenates includedir to _harfbuzz_prefix verbatim,
which results in a wrong final include path in case includedir is an absolute
path. Instead, we can let meson determine the absolute include and lib paths
in advance and save them in the cmake config.

This is an issue in nixpkgs, where includedir is set to the final (absolute)
path of the built library in the Nix store, which causes CMake projects
depending on harfbuzz to not configure.

See https://github.com/NixOS/nixpkgs/issues/180054.

Garret Rieger 70e2de2bd4 [subset] Always output Lookup's even if they are empty.
The rest of layout subsetting depends on lookup indices being consistent with those computed during planning. So if an empty lookup is discarded during the subset phase it will invalidate all subsequent lookup indices. Generally we shouldn't end up with an empty lookup as we pre-prune them during the planning phase, but it can happen in rare cases such as when a subtable is considered degenerate (eg. #3853)

Garret Rieger 9559d3c1c1 [repacker] fix incorrect coverage table size estimation.
During splitting of PairPosFormat2 the code was assuming the maximum size of the generated coverage table would be equal too the current size. This is incorrect size the new coverage table may not preserve the ranges found in the original coverage table (since we are splitting based on class, not coverage) and in the worst case may convert from format2 to format1. So use the size of a format1 table as the max size.

When retain gids is enabled the subset plan may require the output of many empty glyphs. This change optimizes the glyf subsetting code when the number of retained glyphs << number of output glyphs. Unnessecary lookups to the glyph map are reduced by iterating through the glyph map instead of the output glyph set.

Behdad Esfahbod f3151b6582 [ArrayOf family] Use memory barrier before accessing array
Without it, the compiler was reordering and batching the read
of array length and array[0] if the 0'th member was accessed
constantly and function was inlined.  This felt safe to the
compiler because HB_VAR_ARRAY is 1, but could be unsafe actually.
The memory barrier disallows that.

Previous logic was returning zer0.

(where in frame #4 GenericSalLayout::LayoutText, pHbBuffer->props.direction is
HB_DIRECTION_RTL, in case that is relevant).

It is unclear to me whether it is sufficient to only change
hb_graphite2_cluster_t::advance from signed to unsigned int, as there are other
unsigned int variables (like curradv in _hb_graphite2_shape) whose value depend
on hb_graphite2_cluster_t::advance, and which thus might also become negative.
But unlike the float -> unsigned int conversion that UBSan warned about here
(where gr_slot_origin_X() and xscale are float), those are signed int ->
unsigned int conversions that do not cause undefined behavior.  At least, with
this change, the above --convert-to pdf and a full `make check screenshot`
succeeded for me under without further UBSan warnings.

(For the version of HarfBuzz optionally built as part of the LibreOffice build,
this has been addressed with
<https://git.libreoffice.org/core/+/6e53e03f752c2f85283c4d47efaaf0683299783c%5E!/>

negative.")
