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 beatmap listing content swap-out logic was already a source of
several problems, and several attempts of fixing it were made. But as it
turns out it was terminally broken in several aspects.
* The `BypassAutoSizeAxes` juggling was finicky and ugly, and didn't
really look much different than an instant fade. Therefore, all fade
durations and manipulations of `BypassAutoSizeAxes` are removed.
* The transform sequence juggling the `BypassAutoSizeAxes` manipulations
was enqueued on the content which is being in the process of fading
out. That was partially fixed in 25e38560, but as it turns out, that
only works if `lastContent` is one of the two placeholder drawables
(results not found / supporter required to use filter).
It would not work if `lastContent` is a
`ReverseChildIDFillFlowContainer` with cards from a previous search in
it.
The `lastContent == foundContent` check, last touched in a49a4329, is
terminally broken, as it would always be false. `foundContent` is
mutated when a new card load task is started in `onSearchFinished()`,
which is *before* the aforementioned check.
The code prior to a49a4329 was checking against the two static reused
placeholder drawables which was the correct check to apply, and this
commit reverts to using a variant of that check.
During profile, it was found that the `Completed` delegate was
incorrectly also capturing `lastTrack`, leading to an unexpected
reference chain that led to a memory leak over a long period of time.
This solves the issue by moving the delegate construction to its own
method, where it won't capture the other variables.
`BeatmapListingOverlay.addContentToPlaceholder()`, in order to make
transitions between different beatmap listing content (whether it is
actual cards, or placeholders for no beatmaps found/supporter-specific
filters chosen), would set `BypassAutoSizeAxes = Y` on content as it is
fading out, to make the transition smoother. The property in question
was supposed to be getting restored to `None` on the next show.
In testing scenarios, it sometimes turned out that this wasn't the case,
therefore making the placeholders effectively not show - while they
were present and fully opaque, they would be the only child of
an auto-sized container with `BypassAutoSizeAxes = Y`, so the parent
auto-sized to a zero height, which logically follows from the premise,
but is not what was desired.
This in turn was caused by the fact that the `BypassAutoSizeAxes = Y`
set was scheduled, and sometimes it would be scheduled in such a way
that the drawable would cease to be present on the next frame due to its
alpha being past the cutoff point of 0.0001. Therefore the scheduled set
would not execute until the *next* time the placeholder was shown,
therefore causing the bug.
Fix by ensuring that the placeholder drawables are always present if
their schedulers have any tasks enqueued, on top of the usual checks of
alpha and scale performed via the base implementation.
Not the most robust of fixes, but as per the reasoning described in the
issue thread, a proper fix will take considerably more effort. This
intends to fix the issue first and foremost, as it sounds so bad I'd
want to mute my sound before adjusting currently.
Closes#15718.
This fixes stack overflow exceptions that would arise when a
`Current.Value` of 1 billion or more was set on a `SettingsNumberBox`.
The stack overflow was caused by the "maximum 9 digits" spec. If a value
technically within `int` bounds, but larger than 1 billion (in the range
[1,000,000,000; 2,147,483,647], to be more precise), a feedback loop
between the setting control's `Current` and its inner text box's
`Current` would occur, wherein the last digit would be trimmed and then
re-appended again forevermore.
To resolve, remove the offending spec and rely on `int.TryParse`
entirely to be able to discern overflow range. Additionally, UX of the
text box is slightly changed to notify when the `int` range is exceeded
with a red flash.
This behaviour would not have been possible to implement without recent
framework-side fixes to text box (removal of text set scheduling).
Changes all usages of `KeyCombination.ReadableString()` to
`ReadableKeyCombinationProvider.GetReadableString()`.
Subscribing to `KeymapChanged` is only required in `KeyButton`.
All other places query `GetReadableString()` every time.
