This has been wrong from the outside, but hidden by the fact that the
default values are equal. I've changed to MD5Hash which actually asserts
that the correct beatmap has likely arrived.
Found this in my realm changes, where it fails due to the beatmap ID
being a differing Guid in each case.
Previously the slider path length would be snapped using the current
beat snap setting on *every* change of the slider path. As it turns out
this is unexpected behaviour in some situations (e.g. when reversing a
path, which is expected to preserve the previous duration, even though
the slider may be technically "unsnapped" at that point in time due to a
different beat snap setting being selected afterwards).
While displaying replays, the colour of the toolbox toggle button would
not match the actual state of the rest of the toolbox, i.e. both buttons
would be white, even though the "playback settings" section was expanded
and as such should have a yellow toggle button.
In the case of the replay player, the failure scenario was as follows:
1. `SettingsToolboxGroup` calls `updateExpanded()` in its BDL to update
the initial state of the toolbox, including the toggle button
colour, by adding a colour fade transform.
2. An ancestor of both the toolbox groups - `PlayerSettingsOverlay`,
which is a `VisibilityContainer` - calls `FinishTransforms(true)` in
its `LoadCompleteAsync()`, therefore instantly applying the colour
from point (1) to the toggle button instantly.
3. However, `IconButton` inherits from `OsuAnimatedButton`. And
`OsuAnimatedButton` changes its colour in `LoadComplete()`, therefore
undoing the instant application from point (2).
This conjunction of circumstances is instrumental to reproducing the
bug, because if the `FinishTransforms(true)` call wasn't there, point
(3) wouldn't matter - the transform would get applied at some
indeterminate point in the future, ignoring the write from
`OsuAnimatedButton`.
As for the fix, move the `updateExpanded()` call in
`SettingsToolboxGroup` to `LoadComplete()` to avoid the above
unfortunate order. Applying initial visual state in `LoadComplete()` is
the idiomatic style of doing things these days anyhow.
The previous assert step was optimistically assuming that the async
continuation that writes the value of
`FakeImportingPlayer.ImportedScore` always completes before it, but
that's not necessarily true even if the continuation is instant (it is
still subject to things like task scheduling and TPL thread pool
limits).
To ensure no spurious failures, swap out the assert step for an until
step instead.
Was previously not handled at all, therefore displaying request failures
in the test log output. While that was mostly a red herring and
shouldn't have caused any actual *test* failures, it is still better to
handle this explicitly in a realistic manner.
