InspectCode flagged FrameHeader.Mods property initializer = [] as dead code — both constructors unconditionally assign to Mods, so the initializer is never observed.

  • Removed the redundant collection expression initializer on line 69
-public APIMod[] Mods { get; set; } = [];
+public APIMod[] Mods { get; set; }

Due to lack of population of `Storyboard.Beatmap` and
`Storyboard.BeatmapInfo` post-decoding, `LegacyBeatmapExporter` would
completely drop background specifications on exported beatmap packages.
This affects both direct legacy export to file (`.osz`) as well as
beatmap submission.

I will not pretend that the API here is optimal but I do not see very
easy opportunities to curtail misuse. Storyboards can be treated as
either parts of a beatmap or standalone entities, and if a requirement
is added to forcibly provide a beatmap and its info when encoding out a
storyboard, I also foresee a requirement to bypass this later when
design mode is implemented, which would be a return to square one.

There is likely room for cleanup around `Storyboard` to maybe make this
nicer (remove passing of both `Beatmap` and `BeatmapInfo` and just pass
`Beatmap` instead, maybe shuffle some properties from `Beatmap` to
`Storyboard` to remove the requirement of having to bolt the beatmap on
to begin with). I leave voicing opinions on that, and how soon that
should be done, to reviewers. My primary intent at this time is to
hotfix a major issue in a released build.

The external editing feature is not involved in this bug and any
attempts to claim so are misdirections.
Fell out of full-stack testing with
ppy/osu-server-spectator#513.

- **Fix missing property copy in multiplayer client**
Would cause the participant count limit to not update on the multiplayer
match screen.
  

- **Fix hard crash when user is kicked from a room with slots active**
The kicked user is unsubscribed from receiving room state updates before
their slot is vacated, which then would lead this code to attempt to
look the local, kicked user via the unvacated slot and thus fail because
`client.Room.Users` does *not* contain the user anymore.
  
This is a bit of a dicey change but I think it's less dicey than to try
to wiggle ordering server-side.
- Depends on ppy/osu-resources#425.
- Closes ppy#37874

This makes the new combo button use the new icons added in
ppy#37804. Instead of having four separate
icons per ruleset, the "sparkle" texture is overlaid on top of the
appropriate icon.

I'm not sure if I've overdone it with how every ruleset copypastes the
same code for the icon (in `<ruleset>BlueprintContainer`), so that can
be scaled down if necessary.

…afe-mode OpenGL fallback

When GraphicsDevice.CreateVulkan() hangs indefinitely in native Vulkan driver
code, game threads are never created and the user sees a permanent black screen.
The native watchdog now kills the process after 2× the hang threshold (20s) when
no managed heartbeat has ever been observed. This leaves FLAG_STARTUP_IN_PROGRESS
on disk, causing the next launch to enter safe-mode and force OpenGL rendering.

…ppy#37845)

- Part of ppy#37818

During review, I would like to direct particular attention to the
following changes:

## [Migrate song select to new score multiplier
API](ppy@945fd78)

This was a confusing change to write because of the way song selects
hook their mod overlays up to global bindables. In particular different
things happen in different circumstances.

- When going through `SongSelect.CreateModOverlay()`, which is called by
the base `SongSelect`, the mod overlay is automatically bound to global
bindables via `SongSelect.on{ArrivingAt,Leaving}Screen()`.
- For multiplayer user mod select overlays, which are bolted on by
subclasses of `SongSelect`, manual hook-up is required.
- As for free mod select overlays, they don't show mod multipliers at
all, and don't have easy access to the ruleset, and thus the hookup is
skipped entirely as redundant.

## [Fix score multiplier registrations being shared between
implementations via superclass static
fields](ppy@ba0a7ad)

Revealed by `ScoreMultiplierCalculatorTest` starting to fail due to
interference from `OsuScoreMultiplierCalculator`.

It's not ideal from a performance standpoint but it's the simplest
choice for now. Tricks could be pulled to salvage the static. One is

```csharp
public class ScoreMultiplierCalculator<T>
	where T : ScoreMultiplierCalculator<T>
{
}
```

This works because of generics internals; static instance members are
not shared between different specialisations of a generic class. It is
also very unintuitive, so I would rather not. (It trips a ReSharper
inspection too, which would have to be silenced.)

From a performance standpoint this is not ideal, but a significant chunk
of migrated usages already precede the construction of the calculator
via the known-expensive `RulesetInfo.CreateInstance()`, and the paths
that actually construct the calculator do not appear to be that hot. If
need be, this can be handled by actually caching ruleset instances and
their derivative subcomponents.

## [Introduce passing of context to score multiplier
calculator](ppy@9e9242b)

This is required for two reasons:

- The upcoming mod rebalance will require out-of-band supplementary
information that is not available for reading from the mod instances
themselves for calculating the multiplier.
- This context, namely passing of `ScoreInfo`, will be used for
implementing backwards compatibility with old scores and their score
multipliers. This is required because it has turned out under inspection
that all server-side lazer replays recorded until now are missing
`TotalScoreWithoutMods` due to an omission of not sending it across the
wire to spectator server.

Because the score import flow uses replays, filtered through
`LegacyScoreDecoder`, to populate total score in the realm database, it
is basically impossible to ignore scores that are missing
`TotalScoreWithoutMods`, because that will result in bug reports that
the scores do not have the new score multipliers applied.

Thus, passing of `ScoreInfo` will facilitate implementation of
versioning score multipliers, which should result in less breakage than
not doing so.

An example of this is added in 341b2d6,
which should handle the case of mania mod multipliers having been
changed without any attempt to facilitate for it in
ppy#30506.

…py#37919)

- Related to ppy#37818, but of no material
help to it at this point (too late for that)

As noted in
ppy#37845 (comment).

Upon comparison of replays recorded by the client and by the server the
affected fields are: total score without mods, and the list of user
pauses. Additionally, the date of setting the score may differ -
server-side it seems to be written with UTC+0 while client-side it's
written using the local timezone offset. Not really interested in fixing
that last issue at this time.

Also included is an intentionally loud disclaimer in
`LegacyScoreEncoder` to tread with caution when treating the class. Not
sure it'll help, and it's a bit late for it as pretty much every single
versioning primitive has been ravaged to the brink of unusability, but
maybe it'll help someone in the future.

This also cleans up an unnecessary nullable on `FrameHeader.Mods` (added
in ppy#30137). This change can be only done
if users on releases earlier than 2024.1023.0 can no longer connect to
spectator server. I leave it to reviewers to determine this as I have no
visibility over current spectator server configuration. Inspecting the
`osu_builds` table may help confirm this. If it provokes unease, I can
back this change out.

Pull request overview

This PR substantially expands beyond the stated “remove unused property initializer” scope. It updates framework/package versions and refactors score multiplier calculation to be ruleset- and context-driven, then threads the required RulesetInfo bindings through mod-selection UI and updates tests/benchmarks accordingly. It also includes several unrelated functional changes (spectator frame header fields, editor new-combo icon customisation, Android watchdog behaviour, shader fallback).

Changes:

  • Refactor score multiplier handling: add ScoreMultiplierContext, update Ruleset.CreateScoreMultiplierCalculator(...) signature, and migrate all call sites + ruleset implementations.
  • Update mod-selection UI (SongSelect footer button + ModSelectOverlay footer) to compute multipliers via the ruleset calculator and bind RulesetInfo through overlays.
  • Bump framework/resources packages and adjust/disable some tests for timing/rendering differences; add additional changes in spectator/editor/shader/Android watchdog areas.
