Behdad Esfahbod da500568de [API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph

font fallback and to differentiate that from .notdef glyph.

Garret Rieger 6bc64317ca Add a writeup of the overflow resolution algorithm in harfbuzz. 2021-10-12 17:10:07 -06:00
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.

Garret Rieger 307acf7fb0 [repacker] add space assignment based on connected components.

Garret Rieger efda2f14e1 [repacker] fix bug in subgraph isolation.
Prior to this fix id remapping at the end of the isolation operation was fed the old subgraph instead of the new one. Which results in object indices being remapped for the nodes outside of the new subgraph. Adds a test which detects this problem.

2021-09-22 18:18:50 -06:00
Garret Rieger 58facaade1 [repacker] put each 32 bit subgraph into it's own packing space.
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.

Garret Rieger 543a3f9733 [repacker] Add repacker test for subgraph isolation. 2021-09-22 18:18:50 -06:00
Garret Rieger 7147f169d6 [repacker] recursively duplicate nodes during isolation.
If a node is duplicated during isolation then any children it has will have incoming links from outside the subgraph (from the duplicated node and the original node), so they must be duplicated too.

Garret Rieger 8d8b7458a4 [repacker] extract overflows processing into its own method. 2021-09-22 18:18:50 -06:00
Garret Rieger b14b3f13ba [repacker] begin implementing the ability to isolate extension subtables.
Adds isolate_subgraph operation to the repacker. This severs any links from outside a subgraph by duplicating the affected vertices. This will be used to isolate the subgraphs of a extension subtable from the rest of object graph. Thus allowing the extension subtable to be packed far away from the rest of the objects.

Garret Rieger c2cc566c9d [subset] Fix subset_offset_array adding unused space to serializer.
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.

If a cmap4 subtable overflows during serialization drop it and the corresponding EncodingRecord. Don't drop the corresponding cmap12 table if it would have otherwise been removed.
