Ebrahim Byagowi d4588204e5 [draw/glyf] Emit empty contours
This makes it actually match freetype behaviour even though rasterizer
should filter such contours specially for stroking.

See https://github.com/harfbuzz/harfbuzz/pull/3411#discussion_r802283827 for the context.

David Corbett ae9afd9772 Let BCP 47 tag "mo" fall back to OT tag 'ROM ' 2022-01-30 14:32:59 -05:00
David Corbett a184c5f851 Don’t always inherit from macrolanguages
If an OpenType tag maps to a BCP 47 macrolanguage, that is presumably to
support the use of the macrolanguage as a vague stand-in for one of its
individual languages. For example, "ar" and "zh" are often used for
"arb" and "cmn". When the OpenType tag maps to a macrolanguage and some
but not all of its individual languages, that indicates that the
OpenType tag only corresponds to the listed individual languages (which
may be referred to using the macrolanguage subtag) but not the missing
individual languages. In particular, INUK (Nunavik Inuktitut) is mapped
to "ike" (Eastern Canadian Inuktitut) and "iu" (Inuktitut) but not to
"ikt" (Inuinnaqtun), so "ikt" should not inherit the INUK mapping from
its macrolanguage "iu".

cur_intersected_glyphs gets modified during recursion leading to incorrect filtering of sub tables in some cases. So don't use cur_intersected_glyphs. Instead just add an additional entry onto the parent_active_glyphs () stack.

Additionaly expands NotoNastaliqUrdu tests to include coverage of the issue from #3397.

Fix unintentional locale dependency (#3358)
Avoid unintentional locale dependency

hb_variation_to_string uses sprintf with %g, which will produce
a locale-dependent decimal point, which is not desired here.

The output is supposed to be compatible with CSS syntax, and
that always uses '.' for the decimal point.

Fix this by changing the per-thread locale to "C" around sprintf call.

Garret Rieger 441877f56a [repacker] add test case for using max priority to resolve an overflow. 2021-12-09 17:46:52 -07:00
Garret Rieger be2c488e5d [repacker] Improve vertex priority packing.
Previous priority implementation would move a node further back within it's layer, but at max priority was unable to move any further up than that. This updates the implementation to have 3 priority levels:
1. Distance is reduced by half of table size.
2. Distance is reduced by full table size (move to beginning of the layer).
3. Distance is set to 0. Vertex will be packed as soon as possible.

Also makes the iterative resolutions aware of max priority, so it won't keep trying to raise priority beyond the maximum.

Garret Rieger 9121ed0cec [subset] Improve sharing of Ligature subtables.
Ligature subtables use virtual links to enforce an ordering constraint between the subtables and the coverage table. Unfortunately this has the sideeffect of prevent the subtables from being shared by another Ligature with a different coverage table since object equality compares all links real and virtual. This change makes virtual links stored separately from real links and updates the equality check to only check real links. If an object is de-duped any virtual links it has are merged into the object that replaces it.

The current CMAP4 implementation uses whatever the current codepoint ranges are and then encodes them as indivudal glyph ids or as a delta if possible. However, it's often possible to save bytes by splitting up existing ranges and encoding parts of them using deltas where the cost of splitting the range is less than encoding each glyph individual.

Garret Rieger 49c9392412 [subset] During LigatureSubstFormat1 subsetting always place Coverage last.
In Windows 7 on Chrome if the coverage table comes before any of the LigatureSet or Ligature subtables the font won't load. This changes the packing order to always place the Coverage table last. Virtual links are used to ensure the repacker maintains the desired ordering.

Coincidentally fontTools also does the same thing (a3f988fbf6/Lib/fontTools/ttLib/tables/otTables.py (L1137)) to reduce overflows during packing.

Nico Weber 96299d70ed Fix Wbitwise-instead-of-logical warnings
`a || b` only evaluates b if a is false. `a | b` always evaluates
both a and b. If a and b are of type bool, || is usually what you
want, so clang now warns on `|` where both arguments are of type bool.

This warning fires twice in harfbuzz. In both cases, `|` is used
intentionally, with a comment explaining this.

Slightly reorder the code a bit to make the compiler happy, and to
make it obvious even without a comment that both calls should be evaluated.

No intended behavior change.

Each subgraph pointed to by a 32 bit offset should be packed into it's own space. This adds a space property to vertices which affects the distance calculation. This effectively places the distances for all of the nodes of a 32 bit subgraph into a distinct range. Thus all of the nodes of the subgraph will be packed together.

Fix for fuzzer timeout: https://oss-fuzz.com/testcase-detail/5001604901240832.

- Operation limit is per glyph, so 100,000 should still be far more than needed.
- Switches from for(...) to while(...) loop for iteration. for(...) calls it.end() which in this case triggers a complete iteration.
- Cache CompositeGlyph size in the iterator to avoid needing to recalculate it.

are set to false by default. It has been decided that future flags will
also be false by default for simplicity (using NO_ in the name if
needed). Correct and simplify the documentation for hb_subset_flags_t to
reflect this.

Ben Wagner a78eb43c79 Construct user_data in hb_object
hb_object's user_data is created lazily. The previous implementation of
hb_object_set_user_data created space for the user_data but did not
actually construct it. This means that hb_user_data_array_t's lock was
not constructed. If hb_mutex_t is backed by an implementation which
requires that it be constructed (not just zero initialized) then errors
will occur when taking the lock when setting the user data.

Change hb_object_set_user_data to construct the user_data in the created
space and hb_object_fini to call the destructor.

control code points are kept instead of being dropped because there is
not space glyph (otherwise we’d need to identify control code points
somehow when generating the expectations).

As of graphite2 1.3.7, `gr_make_face` is deprecated in favor of

This is potentially a compatibility break since I'm not sure when the

Behdad Esfahbod 23a28f5ad0 Avoid undefined-behavior
If a struct had (because it's a union) sizeof that is larger than the null_size,
we were providing only null_size bytes for its Null object. We know we'd never
access beyond that, but is undefined-behavior nonetheless according to the
standard.

The alternative fix would have required use of flexible-arrays, which are not
standard and have their own issues in various compiler. We've discussed that
extensively in the follow Mozilla issue (currently locked; I've asked that it
be opened):

This should allow checks for max features, max scripts, etc. to be removed.

I tested this change against the full collection of fonts at https://github.com/google/fonts

this stack in order not to change current glyph set at different stages
of recursion

Previous error-handling philosophy was that user doesn't need to

Previous commit didn't fix the bots. Putting it back now that I
understand why I initially did the "Wide" casts.  But only doing
it for out-cast this time.  This causes "narrowing" warnings
whenever we are converting signed/unsigned to smaller HBUINT16
etc.  But those are valuable warnings.  We should address those
separately instead of ignoring.

Maybe we should start using uint16_t more liberally in the
internal subsetter function signatures then.

Enabling the extra cast operator mentioned in previous commit to see if
that fixes this case.

Again, I'd be happy to say "use 1u instead of 1" if this was universally
erred on.  But since some compilers happily compile this while others
err, it would be a huge headache. Let's see...

https://github.com/harfbuzz/harfbuzz/pull/2875
2021-02-22 22:33:17 -07:00
Behdad Esfahbod 567cedcc5f Narrow down cast operators on IntType
Say for USHORT, we were implementing casts from and to unsigned.
With this change, we cast from and to uint16_t only.  This allows
compiler more opportunities to catch possible narrowing issues in
the code.

It needed a couple of fixes in the codebase though, because
previously, if a USHORT was participating in arithmetic with signed
numbers, eg. "u + 1", the result would have been unsigned.  With
this change, it would be signed.  The correct fix is to update the
code to read "u + 1u".

That said, I think about conditionally adding back the cast
out to signed/unsigned, to facilitate better type deduction.
But I couldn't think of a real situation where that would help
with anything.  So I didn't add.  Here's what it was:

  template <typename Type2 = hb_conditional<hb_is_signed (Type), signed, unsigned>,
           hb_enable_if (sizeof (Type) < sizeof (Type2))>
  operator hb_type_identity_t<Type2> () const { return v; }

The immutable objects are a concept only enforced by the C API.
So move checks only to that region.

This does assume that the rest of the code is careful not getting
into these internal methods on immutable objects, which something
we do, but have no way of enforcing (currently).

Garret Rieger 8f47dd5779 [subset] don't set lookup visited in closure_lookups_context_t::recurse.
- Lookup::closure_lookups also checks if the lookups visited and sets the lookup to visited. If we set visited in 'recurse' then Lookup::closure_lookups will fail to recurse into the children of the lookup.
- Also when copying ChainRule's skip LookupRecord's that point to lookups which aren't retained. This matches FontTool's behaviour.

Dominik Röttsches a5f6f869e8 Drop layout table if layout lookup accelerator allocation failed
If the table is kept, when the table is present but only the accelerator
allocation failed, then we run into nullptr dereferences downstream in
hb_ot_map_t::apply when trying to access proxy.accels[i].

To fix this, instead of only setting lookup_count of accelerator_t
itself, drop the whole table to avoid hb-ot-map construction assuming
that the lookups will work correctly despite accelerator allocation
having failed.

David Corbett dec52006d9 Map BCP 47 tags to all macrolanguages
The general rule is that if a BCP 47 macrolanguage maps to an OpenType
language system tag, all its individual languages map to it too.
Previously, a tag like "prs" (Dari) would not map to the language system
tag ('FAR ') of its macrolanguage ("fa") because "prs" already has its
own language system tag ('DRI '). That exception has been removed: now
"prs" maps to 'DRI ' and falls back to 'FAR '.
