fix: resolve 76 CI test failures across encoder roundtrip, HitObjectContainer lifetime, skin editor state, and GC tests by Copilot · Pull Request #360 · winnerspiros/osu

Copilot · 2026-05-27T17:45:56Z

76 test failures across four distinct root causes introduced in the initial branch commit. Each fix is surgical and addresses the underlying logic bug rather than the symptom.

Fixes

LegacyBeatmapEncoder (66 failures — TestEncodeDecodeStability): Removed erroneous HIT_NORMAL → LegacyHitSoundType.Normal case from toLegacyHitSoundType(). The Normal bit is implicit in the legacy format — the decoder derives IsLayered from its absence (type != None && !type.HasFlag(Normal)), so encoding it explicitly breaks the roundtrip for every sample-bearing hit object.
HitObjectContainer (2 failures — TestHitObjectLifetime("non-pooled")): Fixed aliveObjectsSortedCache lifecycle for non-pooled drawables. Add(DrawableHitObject) was calling addDrawable() which immediately inserted into the sorted alive cache, while AddDrawable/RemoveDrawable both returned early for non-pooled entries — leaving all non-pooled objects permanently in AliveObjects regardless of lifetime state. Cache insertion/removal is now driven exclusively by the AddDrawable/RemoveDrawable callbacks for both pooled and non-pooled paths.
TestSceneSkinEditor (5 failures — TestMigrationTriangles + 4 cascade): SetUpSteps reset the skin after base.SetUpSteps() loaded the player, so each test inherited the previous test's skin. TestMigrationArgon left a modified custom argon skin active; the subsequent TestMigrationTriangles player load then failed resolving sh_CursorTrail.vs. Moved AddStep("reset skin", ...) to before base.SetUpSteps().
TestScenePlayerReferenceLeaking (3 failures — GC timeout): Under parallel CI load, a single GC.Collect() was insufficient to collect WorkingBeatmap instances within the 10-second AddUntilStep window. Replaced with a 3-pass forced blocking collection loop:
```
for (int i = 0; i < 3; i++)
{
    GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced, blocking: true);
    GC.WaitForPendingFinalizers();
}
```

- release.yml now supports platform selection (all/android/windows/linux/macos/ios) - Each platform builds in parallel with OS-specific optimizations - Desktop builds: self-contained, single-file, trimmed, compressed, Server GC - README rewritten to cover all platforms, removed Android-only focus - Removed marketing language and device-specific references - Added low-latency audio documentation for all platforms - Added framework-level audio requirements section for mac/ios/linux

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates the fork to a newer ppy.osu.Framework build, migrates away from per-mod ScoreMultiplier overrides toward the new score-multiplier calculator API, and expands the release workflow/docs to cover multi-platform distribution.

Changes:

Bump ppy.osu.Framework* package references from 2026.527.1 → 2026.527.3.
Deprecate Mod.ScoreMultiplier and remove many per-mod overrides/tests relying on the old API.
Rework GitHub Actions release workflow + README to support multi-platform builds/releases.

osu.Game/Rulesets/Mods/Mod.cs:1

Changing ScoreMultiplier from abstract (with meaningful per-mod overrides) to a virtual default of 1 is a behavior-breaking change for any remaining call sites that still read this property (UI display, serialization, logging, etc.). If the intent is full migration, consider introducing/recommending a replacement API for displaying multipliers (or keeping the legacy values temporarily) and updating the remaining consumers to use the calculator; otherwise, multipliers shown/used outside the new calculator path will silently become incorrect.
osu.Game/Rulesets/UI/HitObjectContainer.cs:1
insertIntoAliveCache(drawable) unconditionally inserts into aliveObjectsSortedCache. If AddDrawable() can be invoked more than once for the same drawable without a symmetric RemoveDrawable() (for example due to re-entrant lifetime transitions or unexpected calls), this will produce duplicate cache entries and break consumers iterating AliveObjects. Consider guarding insertion (e.g., track an 'is in alive cache' flag on the drawable/entry, or ensure aliveObjectsSortedCache doesn't already contain the drawable before inserting).
