Outgoing ring timeout no longer restarts on every call state update - #1777
Outgoing ring timeout no longer restarts on every call state update#1777aleksandar-apostolov wants to merge 1 commit into
Conversation
Outgoing was the only RingingState without structural equality, so every updateRingingState() recomputation published a new value on the ringingState StateFlow. Side effects meant to run once per transition ran on every call state update instead: the auto-cancel ring timer restarted its full delay, so a chatty update stream postponed the caller's timeout indefinitely; the outgoing ringtone restarted from the beginning on API 28+, where the RingtoneManager path is not idempotent; the ongoing-call notification was rebuilt and re-posted; and previousRingingStates, a hash set, grew for the lifetime of the ring. Incoming was already a data class, so only the caller side was affected. Every Outgoing consumer uses a type check or reads acceptedByCallee, so nothing depended on identity. The API dump gains only the generated data class members; the constructors are unchanged. Fixes AND-1412

Walkthrough
ChangesRinging state semantics
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change prevents identical outgoing ring updates from resetting timers, restarting ringtone playback, rebuilding notifications, and growing retained state. The runtime fix is localized, but merge readiness is currently moderate because two added tests need repository-compliant setup and a non-ambiguous acceptance assertion. Suggested reviewers: Poem

MockK verify default exactly once or at least once documentation
💡 Result:
In MockK, the verify function uses specific keyword arguments to define how many times a call should have occurred [1][2]. Default Behavior By default, calling verify without specifying a count uses the following settings [1][2]: - atLeast: 1 - atMost: Int.MAX_VALUE - exactly: -1 (which disables the exact count check) This means a standard verify block effectively verifies that the call happened at least once [1][2]. Verification Parameters You can customize the number of times a method is called using these arguments [3][4][2]: - atLeast: Specifies the minimum number of times the call must have occurred [3][2]. - atMost: Specifies the maximum number of times the call is allowed to have occurred [3][2]. - exactly: Specifies the precise number of times the call must have occurred. When this is set to a value other than -1, it overrides the default atLeast and atMost behavior [1][2]. Examples - Verify a call occurred exactly once: verify(exactly = 1) { mock.call } - Verify a call occurred at least once (default): verify { mock.call } // or verify(atLeast = 1) { mock.call } - Verify a call occurred at least three times: verify(atLeast = 3) { mock.call } - Verify a call occurred at most two times: verify(atMost = 2) { mock.call } - Verify a call never occurred: verify(exactly = 0) { mock.call } // or verify(inverse = true) { mock.call } // or verify { mock wasNot Called } Coroutines The same arguments are supported by coVerify for verifying calls within coroutines [1][2].

Isolate the acceptance assertion from the initial Idle emission.
MockK’s default verify {} only requires at least one matching call. Clear recorded calls after the initial drain, or assert the stopCallSound() call after the accepted transition.

Use TestBase for this unit-test class.
RingingStateTest is a fast unit-test class. Make it extend TestBase as required for test sources.

Goal
Fixes AND-1412
A caller could ring far past the configured
autoCancelTimeoutMswithout either side timing out.RingingState.Outgoingwas the only member of the hierarchy without structural equality, andupdateRingingState()allocates a fresh instance on every run — so each recomputation republished the state onCallState.ringingState. Every coordinator API response and eight event handlers reach that path, so a chatty update stream reset the ring timeout from zero, indefinitely.RingingState.Incomingis already adata class, so only the caller side was affected.Found in the Video team's ringing-reliability audit.
Implementation
RingingState.Outgoingbecomes adata class. That restoresStateFlowconflation, which four behaviours depended on:startRingingTimer()no longer cancels and restarts the fullautoCancelTimeoutMsdelay on every update.CallServiceRingingStateObserverno longer restarts the outgoing ringtone. On API 28+playWithRingtoneManagerstops the currentRingtone, builds a new one, and plays it — so the caller heard the tone restart from the beginning on every update. The API <28MediaPlayerpath was already guarded byisPlaying.DefaultNotificationHandler'sdistinctUntilChanged()now filters, so the ongoing-call notification is no longer rebuilt and re-posted per update.previousRingingStatesis a hash set; with nohashCodeevery instance was a distinct member and it grew for the lifetime of the ring.A genuine
acceptedByCalleetransition still passes the change check, so accept handling is unchanged. All 45RingingState.Outgoingusages are type checks or readacceptedByCallee— nothing relied on identity.API dump: additive only — the generated
component1,copy,copy$default,equals,hashCode,toString. Constructors unchanged, so consumers stay binary-compatible. Version constant untouched.The ticket also notes an optional hardening at the timer's fire condition (
Outgoing || (Incoming && activeCall == null)by precedence). Separate concern, left for its own PR.🎨 UI Changes
None.
Testing
New coverage, 8 cases:
RingingStateTest(6) — equality andhashCodeforOutgoingandIncoming, identical states collapsing in a hash set, and theStateFlownot republishing identical outgoing states while still publishing a real acceptance.CallServiceRingingStateObserverTest(+2) — repeated identical outgoing states play the ringtone once; acceptance is still handled after them.Five were verified red with the one-word fix reverted, so they aren't vacuous:
state flow does not republish identical outgoing states,outgoing states with the same acceptance are equal,identical outgoing states collapse in a hash set,repeated identical outgoing states do not restart the outgoing sound,outgoing acceptance still handled after repeated identical states. The other three pass either way — contract guards, not regression proofs.Not covered: the timer restart itself.
CallState.updateRingingState()is only reachable throughIntegrationTestBase, which connects a live coordinator WS, so there is no isolated harness for it. The equality contract is the shared root cause of all four symptoms and is pinned, but this is coverage of the cause rather than the timer.Summary by CodeRabbit
