This patch brings us closer to the spec point of view. And while it
makes no functional changes, it reduces the number of places where you
can misuse scan-specific data and improve support for multiple scans.
10ms (the default) is ridiculous and causes all kinds of glitches if we
actually want to have a low-latency queue.
<https://gitlab.com/qemu-project/qemu/-/issues/1076#note_996636777>
suggests 2ms (and no lower than 1ms). This improves audio glitch
resistance at our current 512 sample buffer size, but going lower is
still not possible.
Nobody made use of the ErrorOr return value and it just added more
chance of confusion, since it was not clear if failing to sniff an
image should return an error or false. The answer was false, if you
returned Error you'd crash the ImageDecoder.
This object is responsible for handling async functions in bytecode,
and this commit fully rewrites it, now it does:
* creates and keeps alive a top level promise, which callers can attach
their `then` clauses
* creates and clear a handle to itself, to assure that it does not get
garbage collected
* properly handles all possible ways a async function could halt and
when possible continues the execution immediately
We use generators in bytecode to approximate async functions, but the
code generated by AwaitExpressions did not have the value processing
paths that Yield requires, eg the `generator.throw()` path, which is
used by AsyncFunctionDriverWrapper to signal Promise rejections.
This uses a newly added instruction `ScheduleJump`
This instruction tells the finally proceeding it, that instead of
jumping to it's next block it should jump to the designated block.
To achieve this it now uses recursive descend, to make the state
managements easier.
With this we now correctly handle try-catch-finally blocks correctly,
modeling all possible controll flows between these blocks, which allows
analysis and optimization passes to make more accurate descisions about
accessibility of the enclosed blocks
The output of the DeprecatedString::bijective_base_from() is now
correct for numbers larger than base^2.
This makes column names display correctly in Spreadsheet.
Turns out extended-lossless-animated.webp did have a loop count of 0.
So I opened it in Hex Fiend and changed the byte at position 42
(which is the first byte of the little-endian u16 storing the loop
count) to 0x2A, so that the test can compare the loop count to something
not 0.
This commit adds a "Apply Mask" action which merges the active layer
mask with the layer bitmap. The option is only displayed if the active
layer is masked.
Imported functions in Wasm may throw JS exceptions, and we need to
preserve these exceptions so we can pass them to the calling JS code.
This also adds a `assert_wasm_result()` API to Result for cases where
only Wasm traps or values are expected (e.g. internal uses) to avoid
making LibWasm (pointlessly) handle JS exceptions that will never show
up in reality.
This is not related to the track controls and it may move into another
separate widget in the future. The move also allows to simplify the
octave slider callback logic.
This more generic name will better reflect the purpose of the widget in
the future, as this commit begins the long process of enhancing the
widget into a container for all controls of Piano's currently selected
track.
