Garret Rieger f94bf9f06f [set fuzzer] limit the total number of set members in a fuzzing input.
Currently the fuzzer can create arbitarily long inputs which once big enough will trigger a timeout.

Khaled Hosny 84dd65a874 [test] Remove timeout from test runners
See https://github.com/harfbuzz/harfbuzz/issues/2707#issuecomment-707744079

This wasn’t inconsistent as well, HB_TEST_SUBSET_FUZZER_TIMEOUT defaulted
to 12 in the test runner, but it was overridden to 50 in meson.build,
and then meson has its own test timeout.

Simon Cozens 7c0bc0bb92 Serialize invalid buffer to !! (text) or [] (json)
There is no generic deserialize - you have to choose glyphs or unicode - so there is no way to deserialize this buffer.

Simon Cozens 3d3c87e7e7 Put the flags back in and serialize clusters.
Note that now JSON glyph buffers and Unicode buffers look very similar, except for the g/u property difference.

Garret Rieger 010accb3d5 [subset] Add additional test cases for the Amiri tests. 2020-09-28 17:39:09 -07:00
Garret Rieger 3271a7cdaa [subset] Remove redundant langys from Amiri test font.
FontTools removes these when subsetting but harfbuzz does not yet support redundant langsys removal. So this gets the Amiri tests passing for now.

[ENOMEM] Return gracefully if stages isn't initialized correctly (#2639)
This happens if calls to 'm.lookups[table_index].push ()' has been
silently failed due to lack of memory.

This change just returns gracefully instead issuing the assert.

Garret Rieger f3929abafe [ENOMEM] don't perform set process operations if the other set is in an error state.
Running a process while the other set is in an error state can potentially corrupt this sets map map (for example by overwritting all of the major values with 0).

Uniscribe enables it by default.
