chat-android/src/main/java/com/ably/chat/ErrorCodes.kt (1)
63-95: Consider reordering room lifecycle error codes sequentiallyThe new error code
RoomReleasedBeforeOperationCompleted(102_106)breaks the sequential ordering of error codes. Consider reordering to maintain numerical sequence:RoomDiscontinuity(102_100), RoomInFailedState(102_101), RoomIsReleasing(102_102), RoomIsReleased(102_103), - - /** - * Room was released before the operation could complete. - */ - RoomReleasedBeforeOperationCompleted(102_106), - /** * Cannot perform operation because the previous operation failed. */ PreviousOperationFailed(102_104), /** * An unknown error has happened in the room lifecycle. */ RoomLifecycleError(102_105), + /** + * Room was released before the operation could complete. + */ + RoomReleasedBeforeOperationCompleted(102_106),chat-android/src/main/java/com/ably/chat/JsonUtils.kt (2)
51-51: Consider enhancing the error message with the actual valueWhile the error handling is correct, consider including the actual value that failed parsing in the error message to aid in debugging.
- ErrorInfo("Required numeric field \"$memberName\" is not a valid long", HttpStatusCode.InternalServerError), + ErrorInfo("Required numeric field \"$memberName\" with value \"${memberElement.asString}\" is not a valid long", HttpStatusCode.InternalServerError),
63-63: Consider enhancing the error message with the actual valueSimilar to the previous suggestion, including the actual value in the error message would improve debugging experience.
- ErrorInfo("Required numeric field \"$memberName\" is not a valid int", HttpStatusCode.InternalServerError), + ErrorInfo("Required numeric field \"$memberName\" with value \"${memberElement.asString}\" is not a valid int", HttpStatusCode.InternalServerError),chat-android/src/main/java/com/ably/chat/RoomOptions.kt (1)
31-42: Document the rationale for default valuesWhile providing default configurations is helpful, it would be beneficial to document why these specific default values were chosen and whether they align with any specifications or best practices.
Consider adding documentation like:
companion object { /** * Supports all room options with default values + * These defaults are based on [reference to spec/documentation] + * - typing: Uses 5000ms timeout as recommended for optimal UX + * - presence: Enables both enter and subscribe modes + * - reactions: Enables basic reaction functionality + * - occupancy: Enables room occupancy tracking */ val default = RoomOptions(chat-android/src/test/java/com/ably/chat/RoomReactionsTest.kt (2)
40-40: Consider adding logger interaction verificationWhile the logger is properly injected, consider adding test cases to verify logger interactions, especially for error scenarios or important lifecycle events.
Example verification:
verify(exactly = 1) { logger.debug(any(), any()) }
Line range hint
46-57: Consider adding negative test casesThe test verifies the happy path for channel name specification, but consider adding test cases for:
- Invalid room IDs
- Error logging scenarios
- Edge cases in channel name formatting
Example test case:
@Test fun `should log error when room ID is invalid`() = runTest { val roomReactions = DefaultRoomReactions( roomId = "", // Invalid room ID clientId = "client1", realtimeChannels = realtimeChannels, logger, ) verify { logger.error(any(), any()) } }chat-android/src/test/java/com/ably/chat/room/RoomTestHelpers.kt (5)
30-31: Add KDoc documentation for mock creation utilities.Consider adding KDoc documentation to describe the purpose and behavior of these utility functions, especially noting that the realtime client is created with
autoConnect = false.+/** + * Creates a spied instance of AblyRealtime with autoConnect disabled. + * @return Spied AblyRealtime instance + */ fun createMockRealtimeClient(): AblyRealtime = spyk(AblyRealtime(ClientOptions("id:key").apply { autoConnect = false })) +/** + * Creates a relaxed mock of AndroidLogger. + * @return Mocked Logger instance + */ internal fun createMockLogger(): Logger = mockk<AndroidLogger>(relaxed = true)
34-36: Add documentation and internal visibility for Rooms extensions.Consider adding KDoc documentation and marking these properties as internal since they're test utilities.
-val Rooms.RoomIdToRoom get() = getPrivateField<MutableMap<String, Room>>("roomIdToRoom") -val Rooms.RoomGetDeferred get() = getPrivateField<MutableMap<String, CompletableDeferred<Unit>>>("roomGetDeferred") -val Rooms.RoomReleaseDeferred get() = getPrivateField<MutableMap<String, CompletableDeferred<Unit>>>("roomReleaseDeferred") +/** Access to private roomIdToRoom map for testing. */ +internal val Rooms.RoomIdToRoom get() = getPrivateField<MutableMap<String, Room>>("roomIdToRoom") +/** Access to private roomGetDeferred map for testing. */ +internal val Rooms.RoomGetDeferred get() = getPrivateField<MutableMap<String, CompletableDeferred<Unit>>>("roomGetDeferred") +/** Access to private roomReleaseDeferred map for testing. */ +internal val Rooms.RoomReleaseDeferred get() = getPrivateField<MutableMap<String, CompletableDeferred<Unit>>>("roomReleaseDeferred")
48-52: Add error handling to atomicRetry operation.The atomic retry operation should handle potential exceptions to prevent them from propagating up the call stack unexpectedly during tests.
internal suspend fun RoomLifecycleManager.atomicRetry(exceptContributor: ContributesToRoomLifecycle) { - atomicCoroutineScope().async(LifecycleOperationPrecedence.Internal.priority) { - retry(exceptContributor) - }.await() + try { + atomicCoroutineScope().async(LifecycleOperationPrecedence.Internal.priority) { + retry(exceptContributor) + }.await() + } catch (e: Exception) { + // Log the error but don't fail the test + println("Warning: Atomic retry failed: ${e.message}") + } }
54-73: Make clientId configurable and add parameter validation.The function uses a hard-coded clientId and lacks parameter validation. Consider making it configurable and adding basic validation.
-fun createRoomFeatureMocks(roomId: String = "1234"): List<ContributesToRoomLifecycle> { - val clientId = "clientId" +fun createRoomFeatureMocks( + roomId: String = "1234", + clientId: String = "clientId" +): List<ContributesToRoomLifecycle> { + require(roomId.isNotBlank()) { "roomId cannot be blank" } + require(clientId.isNotBlank()) { "clientId cannot be blank" } val realtimeClient = createMockRealtimeClient()
75-78: Add state transition validation to setState.Consider adding validation to ensure the state transition is valid according to the Ably channel state machine.
fun AblyRealtimeChannel.setState(state: ChannelState, errorInfo: ErrorInfo? = null) { + // Validate that the transition from current state to new state is valid + val isValidTransition = when (this.state) { + ChannelState.initialized -> true // Can transition to any state + ChannelState.attaching -> state in listOf(ChannelState.attached, ChannelState.failed) + ChannelState.attached -> state in listOf(ChannelState.detaching, ChannelState.failed) + else -> true // Allow other transitions for testing flexibility + } + require(isValidTransition) { "Invalid state transition from ${this.state} to $state" } + this.state = state this.reason = errorInfo }chat-android/src/test/java/com/ably/chat/TestUtils.kt (1)
71-80: Consider optimizing the polling mechanismWhile the implementation is functional, consider these improvements for better efficiency and robustness:
- Add exponential backoff for the delay to reduce resource consumption
- Add a way to break early if the condition becomes impossible to satisfy
Consider this alternative implementation:
suspend fun assertWaiter(timeoutInMs: Long = 10_000, block: () -> Boolean) { withContext(Dispatchers.Default) { withTimeout(timeoutInMs) { + var waitMs = 50L // Start with shorter delay do { val success = block() - delay(100) + if (!success) { + delay(waitMs) + waitMs = (waitMs * 1.5).toLong().coerceAtMost(1000) // Exponential backoff, max 1s + } } while (!success) } } }chat-android/src/test/java/com/ably/chat/room/RoomIntegrationTest.kt (3)
48-53: Consider enhancing state change validation.While the state changes are being validated, consider adding assertions for the
previousstate inRoomStatusChangeto ensure correct transition paths.Example enhancement:
Assert.assertEquals(5, stateChanges.size) Assert.assertEquals(RoomStatus.Attaching, stateChanges[0].current) +Assert.assertEquals(RoomStatus.Initialized, stateChanges[0].previous) Assert.assertEquals(RoomStatus.Attached, stateChanges[1].current) +Assert.assertEquals(RoomStatus.Attaching, stateChanges[1].previous) Assert.assertEquals(RoomStatus.Detaching, stateChanges[2].current) +Assert.assertEquals(RoomStatus.Attached, stateChanges[2].previous) Assert.assertEquals(RoomStatus.Detached, stateChanges[3].current) +Assert.assertEquals(RoomStatus.Detaching, stateChanges[3].previous) Assert.assertEquals(RoomStatus.Released, stateChanges[4].current) +Assert.assertEquals(RoomStatus.Detached, stateChanges[4].previous)
73-78: Consider consistent state validation improvements.Similar to the previous suggestion, consider enhancing the state change validation here as well.
Example enhancement:
Assert.assertEquals(4, stateChanges.size) Assert.assertEquals(RoomStatus.Attaching, stateChanges[0].current) +Assert.assertEquals(RoomStatus.Initialized, stateChanges[0].previous) Assert.assertEquals(RoomStatus.Attached, stateChanges[1].current) +Assert.assertEquals(RoomStatus.Attaching, stateChanges[1].previous) Assert.assertEquals(RoomStatus.Releasing, stateChanges[2].current) +Assert.assertEquals(RoomStatus.Attached, stateChanges[2].previous) Assert.assertEquals(RoomStatus.Released, stateChanges[3].current) +Assert.assertEquals(RoomStatus.Releasing, stateChanges[3].previous)
80-102: Consider adding documentation for test scenarios.While the test methods are well-structured, consider adding documentation to explain the difference between using a sandbox client vs. a connected client, and why both scenarios need to be tested.
Example enhancement:
+ /** + * Validates room lifecycle operations with a newly created sandbox client. + * This ensures the functionality works when starting with a fresh connection. + */ @Test fun `should be able to Attach, Detach and Release Room`() = runTest { + /** + * Validates room lifecycle operations with a pre-connected client. + * This ensures the functionality works with an established connection, + * which might have different timing characteristics. + */ @Test fun `should be able to Attach, Detach and Release Room for connected client`() = runTest {chat-android/src/test/java/com/ably/chat/PresenceTest.kt (1)
32-32: Consider adding test cases for logging behaviorWhile the logger is now properly initialized in the setup, there are no assertions verifying that appropriate logging occurs during presence events.
Consider adding test cases to verify logging behavior:
@Test fun `should log presence subscription events`() = runTest { // Arrange val presenceListenerSlot = slot<PresenceListener>() every { pubSubPresence.subscribe(capture(presenceListenerSlot)) } returns Unit // Act presence.subscribe { } // Assert verify { logger.debug(any(), any()) } }chat-android/src/test/java/com/ably/chat/room/ConfigureRoomOptionsTest.kt (3)
15-25: Consider enhancing the documentation with test scenarios.While the documentation clearly explains the purpose, it would be helpful to add specific test scenarios covered by this class. For example:
- Validation of typing timeout
- Feature enablement/disablement checks
/** * Chat rooms are configurable, so as to enable or disable certain features. * When requesting a room, options as to which features should be enabled, and * the configuration they should take, must be provided + * + * Test scenarios: + * 1. Validation of typing timeout (must be positive) + * 2. Validation of feature access based on configuration + * * Spec: CHA-RC2 */
26-43: Consider adding boundary value tests for typing timeout.While the test covers positive and negative scenarios, consider adding tests for edge cases:
- Zero timeout
- Maximum allowed timeout value
- Timeout value at Integer.MAX_VALUE
@Test fun `(CHA-RC2a) Additional timeout validation scenarios`() = runTest { val mockRealtimeClient = createMockRealtimeClient() val chatApi = mockk<ChatApi>(relaxed = true) // Test zero timeout assertThrows(AblyException::class.java) { DefaultRoom("1234", RoomOptions(typing = TypingOptions(timeoutMs = 0)), mockRealtimeClient, chatApi, clientId, logger) } // Test maximum allowed timeout val room = DefaultRoom("1234", RoomOptions(typing = TypingOptions(timeoutMs = Int.MAX_VALUE)), mockRealtimeClient, chatApi, clientId, logger) Assert.assertNotNull(room) }
1-94: Well-structured tests with room for enhancement.The test implementation effectively validates room configuration and feature access. Consider these architectural improvements:
- Create a base test class with common setup code
- Use test fixtures for common test data
- Consider parameterized tests for feature validation
chat-android/src/test/java/com/ably/chat/room/lifecycle/PrecedenceTest.kt (4)
27-31: Enhance class documentation with test scenarios.The class documentation clearly references the specification but could be enhanced by including a brief overview of the test scenarios covered.
/** * Room lifecycle operations are atomic and exclusive operations: one operation must complete (whether that's failure or success) before the next one may begin. * Spec: CHA-RL7 + * + * Test Scenarios: + * - Verifies operation precedence order: RETRY > RELEASE > ATTACH/DETACH + * - Validates atomic execution of operations + * - Ensures operation queuing and cancellation behavior */
43-56: Consider breaking down the long test method.While the test is well-structured, its length suggests it could benefit from being split into smaller, focused test methods for each precedence scenario.
Consider refactoring into separate test methods:
- Test RETRY precedence
- Test RELEASE precedence
- Test ATTACH/DETACH precedence
This would improve readability and maintenance while making the test failures more specific.
57-62: Improve error message in retry operation mock.The current error message "throwing error to avoid continuation getting stuck :(" could be more descriptive about why this is necessary.
- error("throwing error to avoid continuation getting stuck :( ") + error("Simulated failure to terminate retry operation (required to prevent continuation from blocking)")
102-118: Enhance assertion messages for better failure diagnosis.While the assertions are comprehensive, adding descriptive messages would make test failures more informative.
- Assert.assertEquals(6, roomStatusChanges.size) + Assert.assertEquals("Expected 6 status changes in total", 6, roomStatusChanges.size) - Assert.assertEquals(RoomStatus.Attaching, roomStatusChanges[0].current) + Assert.assertEquals("First status should be Attaching", RoomStatus.Attaching, roomStatusChanges[0].current)chat-android/src/main/java/com/ably/chat/ChatApi.kt (1)
120-120: Consider extracting common error handling logicWhile the error handling is correct, there's similar empty response handling in both
sendMessageandgetOccupancymethods.Consider extracting this common error handling into a utility function:
private fun createEmptyResponseError(endpoint: String): AblyException { return AblyException.fromErrorInfo( ErrorInfo("$endpoint returned empty value", HttpStatusCode.InternalServerError) ) }This would reduce duplication and make future updates easier.
chat-android/src/main/java/com/ably/chat/Utils.kt (2)
130-135: Consider improving error message handling robustnessThe current implementation has a few potential issues:
- The comma prefix could cause formatting issues when concatenating with other strings
- No handling for null message in ErrorInfo
- Property name could be more specific
Consider this improved implementation:
-val Channel.errorMessage: String - get() = if (reason == null) { - "" - } else { - ", ${reason.message}" - } +val Channel.reasonMessage: String + get() = reason?.message?.takeIf { it.isNotEmpty() } + ?.let { " ($it)" } + ?: ""This change:
- Renames the property to better reflect its purpose
- Uses parentheses instead of comma for better formatting
- Handles empty messages gracefully
- Uses more idiomatic Kotlin syntax
208-212: Add KDoc documentation for public error handling functionsThe public error handling functions lack documentation explaining their purpose, parameters, and return values. This documentation is crucial for API consumers.
Add KDoc documentation:
+/** + * Creates an ErrorInfo instance for lifecycle-related errors with Internal Server Error status. + * + * @param errorMessage The descriptive message for the error + * @param errorCode The specific error code from ErrorCode enum + * @return ErrorInfo instance with the specified error details + */ fun lifeCycleErrorInfo( errorMessage: String, errorCode: ErrorCode, ) = createErrorInfo(errorMessage, errorCode, HttpStatusCode.InternalServerError)chat-android/src/test/java/com/ably/chat/room/RoomGetTest.kt (5)
27-29: Enhance class documentation with spec details.The spec reference "CHA-RC1f" could be more descriptive. Consider adding a brief description of what this specification covers to improve documentation clarity.
/** - * Spec: CHA-RC1f + * Tests implementing the Room Lifecycle Specification (CHA-RC1f) + * covering room retrieval operations and concurrent access scenarios. */
34-43: Add verification for ChatApi interaction.The test verifies the returned room properties but doesn't verify if the
ChatApiwas properly utilized. Consider adding verification to ensure the chat API was called correctly.@Test fun `(CHA-RC1f) Requesting a room from the Chat Client return instance of a room with the provided id and options`() = runTest { val mockRealtimeClient = createMockRealtimeClient() val chatApi = mockk<ChatApi>(relaxed = true) val rooms = DefaultRooms(mockRealtimeClient, chatApi, ClientOptions(), clientId, logger) val room = rooms.get("1234", RoomOptions()) Assert.assertNotNull(room) Assert.assertEquals("1234", room.roomId) Assert.assertEquals(RoomOptions(), room.options) + verify { chatApi.validateRoomId("1234") } }
137-219: Document the test flow stages for better clarity.This complex test would benefit from clear documentation of its stages. Consider adding comments to explain the test flow and expectations at each stage.
@Test fun `(CHA-RC1f4, CHA-RC1f5) If CHA-RC1g release operation is in progress, new instance should not be returned until release operation completes`() = runTest { + // Test stages: + // 1. Setup: Create initial room and mock release behavior + // 2. Start concurrent operations: Release room and request same room + // 3. Verify intermediate state: Room is releasing and get operation is waiting + // 4. Complete release: Trigger room release completion + // 5. Verify final state: New room is created and operations complete in correct order + val roomId = "1234" // ... rest of the test }
1-220: Consider organizing test utilities into a base test class.The test class could benefit from better organization:
- Common setup code (createMockRealtimeClient, createMockLogger) could be moved to a base test class
- Helper functions for common assertions could reduce code duplication
- Consider using a test fixture for common room creation scenarios
However, based on the retrieved learnings indicating that duplicate code is acceptable for readability in tests, this is just a suggestion for consideration.
30-30: Add test coverage for invalid room IDs.Consider adding a test case to verify behavior when invalid room IDs are provided (e.g., empty strings, invalid characters, etc.).
Example test:
@Test fun `get throws exception for invalid room ID`() = runTest { val rooms = DefaultRooms(createMockRealtimeClient(), mockk(), ClientOptions(), clientId, logger) assertThrows(AblyException::class.java) { runBlocking { rooms.get("", RoomOptions()) } } }chat-android/src/main/java/com/ably/chat/Messages.kt (1)
325-340: Consider reducing code duplication in serial requirement methodsThe error handling code is duplicated between
requireChannelSerialandrequireAttachSerial. Consider extracting the common error creation logic.+ private fun createSerialError(message: String): ErrorInfo = + ErrorInfo(message, HttpStatusCode.BadRequest, ErrorCode.BadRequest.code) private fun requireChannelSerial(): String { return channel.properties.channelSerial - ?: throw AblyException.fromErrorInfo( - ErrorInfo( - "Channel has been attached, but channelSerial is not defined", - HttpStatusCode.BadRequest, - ErrorCode.BadRequest.code, - ), - ) + ?: throw AblyException.fromErrorInfo( + createSerialError("Channel has been attached, but channelSerial is not defined") + ) } private fun requireAttachSerial(): String { return channel.properties.attachSerial - ?: throw AblyException.fromErrorInfo( - ErrorInfo( - "Channel has been attached, but attachSerial is not defined", - HttpStatusCode.BadRequest, - ErrorCode.BadRequest.code, - ), - ) + ?: throw AblyException.fromErrorInfo( + createSerialError("Channel has been attached, but attachSerial is not defined") + ) }chat-android/src/test/java/com/ably/chat/room/lifecycle/ReleaseTest.kt (3)
35-48: Consider cleaning up the coroutine scope in tearDown.While the static mocks are properly cleaned up, the
roomScopeshould be cancelled in the tearDown method to prevent potential coroutine leaks.@After fun tearDown() { unmockkStatic(io.ably.lib.realtime.Channel::attachCoroutine) + roomScope.cancel() // Clean up coroutines }
190-228: Consider extracting magic numbers as constants.The delay values (250ms, 200ms) should be extracted as constants at the class level for better maintainability and clarity.
+ companion object { + private const val DETACH_DELAY_MS = 200L + private const val RETRY_DELAY_MS = 250L + } @Test fun `(CHA-RL3f) If a one of the contributors fails to detach, release op continues for all contributors after 250ms delay`() = runTest { // ... coEvery { any<io.ably.lib.realtime.Channel>().detachCoroutine() } coAnswers { - delay(200) + delay(DETACH_DELAY_MS) if (--failDetachTimes >= 0) { error("failed to detach channel") } // ... } // ... }
1-381: Consider adding property-based tests for more edge cases.While the current test suite is comprehensive, consider adding property-based testing (e.g., using kotest-property) for:
- Different combinations of contributor states
- Various numbers of contributors
- Different timing scenarios
This would help discover edge cases that might not be covered by the current deterministic tests.
chat-android/src/main/java/com/ably/chat/Discontinuities.kt (1)
46-47: Avoid Shadowing theloggerVariableThe constructor parameter
loggeris being shadowed by the propertyprivate val logger, which can lead to confusion. Consider renaming either the constructor parameter or the property to improve clarity.Apply this diff to rename the constructor parameter:
-internal class DiscontinuityEmitter(logger: Logger) : EventEmitter<String, EmitsDiscontinuities.Listener>() { +internal class DiscontinuityEmitter(parentLogger: Logger) : EventEmitter<String, EmitsDiscontinuities.Listener>() { private val logger = parentLogger.withContext("DiscontinuityEmitter")chat-android/src/main/java/com/ably/chat/Connection.kt (3)
6-6: Add missing word in documentation commentThere's a missing word in the documentation comment. It should read: "before we attempt to handle them as a state change."
8-8: Consider renamingTRANSIENT_TIMEOUTtoTRANSIENT_TIMEOUT_MSfor clarityTo make it clear that the timeout is in milliseconds, consider renaming the constant to
TRANSIENT_TIMEOUT_MS.
88-88: Use correct KDoc tag@returninstead of@returnsIn Kotlin documentation, the correct tag for return values is
@return, not@returns.chat-android/src/test/java/com/ably/chat/Sandbox.kt (1)
74-76: Simplify code by omitting unnecessarythiskeywordsIn Kotlin, using
thisis optional when accessing members of the current instance, unless needed for disambiguation.Simplify the code for readability:
- if (this.connection.state == ConnectionState.connected) { + if (connection.state == ConnectionState.connected) {chat-android/src/main/java/com/ably/chat/AtomicCoroutineScope.kt (1)
89-92: Consider clearing thejobsqueue in thecancelmethodIn the
cancelmethod, you resetqueueCounterand cancel child coroutines:@Synchronized fun cancel(message: String?, cause: Throwable? = null) { queueCounter = 0 sequentialScope.coroutineContext.cancelChildren(CancellationException(message, cause)) }However, the
jobsqueue remains untouched, leaving pending jobs in the queue, which may lead to unintended execution when new jobs are added.To ensure all pending jobs are canceled, consider clearing the
jobsqueue:@Synchronized fun cancel(message: String?, cause: Throwable? = null) { queueCounter = 0 + jobs.clear() sequentialScope.coroutineContext.cancelChildren(CancellationException(message, cause)) }This change ensures that no pending jobs are left in the queue after cancellation.
chat-android/src/main/java/com/ably/chat/RoomReactions.kt (1)
149-149: Consider changingHttpStatusCode.InternalServerErrortoBadRequestFor the error "Unrecognized Pub/Sub channel's message for
roomReactionevent", usingHttpStatusCode.InternalServerErrormight suggest a server-side issue. Consider usingHttpStatusCode.BadRequestto indicate that the client sent invalid data.chat-android/src/main/java/com/ably/chat/Rooms.kt (1)
127-158: Consider enhancing readability of 'getReleasedOrExistingRoom'The
getReleasedOrExistingRoommethod contains complex logic for handling room retrieval during concurrent operations. While refactoring into smaller methods is not preferred (as per your previous feedback), adding clarifying comments or inline documentation could improve maintainability and assist future developers in understanding the flow.As per your previous guidance:
Learning: In the Kotlin file `chat-android/src/main/java/com/ably/chat/Rooms.kt`, avoid refactoring methods like `getReleasedOrExistingRoom` into smaller methods, as having extra methods makes it hard to correlate the code in this project.chat-android/src/main/java/com/ably/chat/Typing.kt (1)
195-195: Consider Using a More Specific Error CodeIn the exception thrown when
optionsis not initialized,ErrorCode.BadRequest.codeis used. Consider defining a more specific error code to provide clearer insight into the error's origin.chat-android/src/main/java/com/ably/chat/Room.kt (1)
135-169: Refactor repetitive null-check logic in feature gettersThe getters for
_presence,_reactions,_typing, and_occupancycontain similar null-check logic. To enhance maintainability and reduce code duplication, consider abstracting this logic into a common function or using property delegation with a custom delegate that handles the null-check and exception throwing.chat-android/src/test/java/com/ably/chat/room/lifecycle/RetryTest.kt (2)
142-142: Correct grammatical errors in test function nameThe function name has grammatical issues. It would be clearer and grammatically correct to phrase it as: "If all contributor channels go into detached (except the one provided in suspended state), the provided contributor starts attach operation and waits for ATTACHED or FAILED state."
Apply this diff to correct the grammar:
-fun `(CHA-RL5d) If all contributor channels goes into detached (except one provided in suspended state), provided contributor starts attach operation and waits for ATTACHED or FAILED state`() = runTest { +fun `(CHA-RL5d) If all contributor channels go into detached (except the one provided in suspended state), the provided contributor starts attach operation and waits for ATTACHED or FAILED state`() = runTest {
54-55: Refactor to reduce code duplication by extracting common setup codeThe code to mock the static methods
attachCoroutineanddetachCoroutineis repeated across multiple test methods. Consider refactoring this common setup into a@Beforemethod to enhance maintainability and adhere to the DRY (Don't Repeat Yourself) principle.Apply this refactor:
Add a
@Beforemethod:@Before fun setUp() { mockkStatic(io.ably.lib.realtime.Channel::attachCoroutine) mockkStatic(io.ably.lib.realtime.Channel::detachCoroutine) coJustRun { any<io.ably.lib.realtime.Channel>().attachCoroutine() } coJustRun { any<io.ably.lib.realtime.Channel>().detachCoroutine() } }Update the
tearDownmethod to un-mock both methods:@After fun tearDown() { unmockkStatic(io.ably.lib.realtime.Channel::attachCoroutine) + unmockkStatic(io.ably.lib.realtime.Channel::detachCoroutine) }Also applies to: 86-87, 116-117, 145-147, 183-185, 209-210
chat-android/src/test/java/com/ably/chat/room/RoomReleaseTest.kt (2)
128-181: Consider adding comments to explain the high number of repetitions in concurrency test.Repeating the release operation 1000 times simulates concurrent release attempts. Adding a comment to clarify the intent and necessity of this number can aid future maintainers in understanding the test's purpose.
183-284: Enhance complex test with additional comments for clarity.Given the length and complexity of this test method, consider adding inline comments to improve readability and help others understand the test flow and purpose more easily.
chat-android/src/test/java/com/ably/chat/room/lifecycle/DetachTest.kt (3)
59-84: Refactor common setup code in test methodsThe test methods from lines 59 to 84 share similar setup code for initializing
statusLifecycleandroomLifecycle. Extracting this code into a@Beforemethod or a helper function can reduce duplication and improve maintainability.
142-173: Avoid suppressing maximum line length warningsInstead of using the
@Suppress("MaximumLineLength")annotation at line 142, consider reformatting the code to adhere to the maximum line length specified in your coding guidelines. This improves code readability and maintains consistency with style standards.
229-241: Use predefined constants for HTTP status codesAt lines 231 and 237, when creating
ErrorInfoobjects, replace the hardcoded status code500withHttpStatusCode.InternalServerError. This enhances code clarity and reduces the risk of errors associated with magic numbers.Apply this diff to use the predefined constant:
- val error = ErrorInfo("error detaching channel ${channel.name}", 500) + val error = ErrorInfo("error detaching channel ${channel.name}", HttpStatusCode.InternalServerError)chat-android/src/test/java/com/ably/chat/room/lifecycle/AttachTest.kt (1)
248-259: Clarify the contributor being tested in commentsThe comment mentions "Throw error for typing contributor," but the condition checks for
"reactions"inchannel.name. This inconsistency may lead to confusion.Update the comment to reflect the actual contributor being tested to improve code clarity.
Apply this diff to correct the comment:
- // Throw error for typing contributor, likely to throw because it uses different channel + // Throw error for reactions contributor to simulate attach failurechat-android/src/main/java/com/ably/chat/RoomLifecycleManager.kt (4)
160-160: Reminder: Implement room monitoring as per specificationThere's a TODO comment indicating that room monitoring needs to be set up (
// TODO - [CHA-RL4] set up room monitoring here). Please implement the room monitoring functionality according to the specification CHA-RL4 to ensure complete lifecycle management.Would you like assistance in implementing the room monitoring feature?
433-475: RefactordoChannelWindDown()for better clarityThe
doChannelWindDown()method is marked with suppression annotations forCognitiveComplexMethodandComplexCondition, indicating high complexity. Consider breaking this method into smaller helper functions to enhance code clarity and reduce cognitive load.
627-629: Implement error logging before rethrowing exceptionsThere's a TODO comment at line 627 stating
// TODO - log error here before rethrowing. Implement proper logging of exceptions before rethrowing them to aid in debugging and monitoring potential issues during the release process.Would you like assistance in adding the appropriate logging here?
155-157: MakeretryDurationInMsconfigurableThe
retryDurationInMsis hardcoded to 250 milliseconds. To allow flexibility under different network conditions or application requirements, consider making this value configurable, possibly through a constructor parameter or a configuration file.

Learning: In `AtomicCoroutineScope`, calling `cancel()` uses `sequentialScope.coroutineContext.cancelChildren` to cancel all child jobs. The `CancellationException` is caught in `safeExecute`, ensuring that `isRunning` is set to `false` after all queued jobs are processed, allowing new jobs to be accepted.

The test effectively verifies occupancy functionality with:
- Proper setup of occupancy options
- Clear async handling using CompletableDeferred

Line range hint 34-47: Verify the custom typing timeout value.
The test uses a 10,000ms timeout which differs from the default 5,000ms mentioned in the summary. While the test is well-structured, please confirm if this increased timeout is intentional for the test case.
✅ Verification successful
Let me gather more information about the default timeout value.
Test's increased typing timeout is intentional and valid
The increased timeout of 10,000ms in the test is intentional and appropriate:
- The default timeout is documented as 5,000ms in
RoomOptions.kt - The test is validating that custom timeout values work correctly
- Other tests in the codebase also use custom timeout values (e.g., 1,500ms in
RoomGetTest.kt) - The codebase explicitly validates that timeout values must be positive, showing that custom values are supported by design

88-98: Enhance error message and verify spec requirement
The validation implementation looks good, but consider these improvements:
- The error message could be more descriptive, e.g., include the actual value
- Based on previous learnings about adding validations only when required by spec, we should verify that CHA-RC2a explicitly requires this validation
Consider enhancing the error message:
- throw ablyException("Typing timeout must be greater than 0", ErrorCode.InvalidRequestBody)
+ throw ablyException("Typing timeout must be greater than 0 (current value: ${typing.timeoutMs}ms)", ErrorCode.InvalidRequestBody)Let's verify the spec requirement:
✅ Verification successful
Validation is correctly implemented per spec CHA-RC2a
The validation is explicitly required by the spec CHA-RC2a as evidenced by the test case. The error message suggestion is good but optional since the current implementation matches the exact error message verified in the test case.
- Test case
(CHA-RC2a)explicitly verifies that negative typing timeout must throw an error with code 40001 - Current implementation correctly validates this requirement with matching error message

73-75: Verify the impact of reduced typing timeout
The typing timeout has been reduced from 10 seconds to 5 seconds. While the documentation is updated, we should verify:
- The rationale behind this change
- Whether this aligns with industry standards or user experience research
- The potential impact on existing implementations
Let's check if this timeout value is used consistently:
✅ Verification successful
Let me gather more context about the rationale and consistency of this change.
Let me try one more verification to check the implementation details and any comments that might explain this timeout value.
Based on the gathered information, I can now provide the final response:
The typing timeout change appears to be a reasonable optimization
The reduced timeout of 5 seconds is well-justified based on the implementation and usage patterns found in the codebase:
- The timeout is used solely for managing typing indicator presence, where the timer resets on each typing event
- The implementation includes a robust retry mechanism for presence updates
- Test cases show the system works with various timeout values (including 1500ms)
- The value is validated to be greater than 0, ensuring system stability
The change aligns with common UX patterns where typing indicators should be responsive and quick to update, and the implementation's auto-reset behavior ensures active typers remain visible.

Version update appears safe to proceed
The Ably SDK version update from 1.2.43 to 1.2.45 appears to be a minor version bump. The codebase shows:
- No version-specific implementations or dependencies
- Standard usage of Ably's Channel and Realtime APIs
- New RoomLifecycleManager implementation using core Ably functionality

- Production
Room.ktuseslimitedParallelism(1)withSupervisorJob() - Other production components like
Typing.kt,Occupancy.kt, andRooms.ktalso use the same configuration - Test configuration matches this pattern, only differing by omitting
SupervisorJob()which is appropriate for test scenarios

Let's verify that release is called appropriately:
✅ Verification successful
Let me analyze the release method calls in the codebase to verify its proper usage.
The search results show that:
- The
release()method in Messages.kt is part of a larger resource cleanup system - It's called through the
RoomLifecycleManagerwhich orchestrates the release of all components - The release order is properly managed:
- First removes channel state listener
- Then releases the channel from realtimeChannels
- Other components (Typing, RoomReactions, Presence, Occupancy) also implement release() with appropriate cleanup
- Tests verify the release behavior extensively, including proper state transitions and error cases
LGTM: Release implementation follows proper cleanup pattern

1-34: LGTM! Well-organized imports.
The imports are properly categorized and include all necessary dependencies for testing coroutines, mocking, and assertions.
50-97: LGTM! Well-structured basic state transition tests.
The first three tests effectively cover the basic state transitions (Released, Detached, Initialized). Good use of status change tracking and assertions.
230-274: LGTM! Robust error handling test with randomization.
The test effectively uses randomization to verify behavior across different channel states, aligning with the previous learning about intentional randomness in tests.
322-380: LGTM! Comprehensive operation ordering test.
The test thoroughly verifies the operation ordering requirements (CHA-RL7) with proper coroutine handling and state assertions. The use of Channel for synchronization is a good practice.
detekt.yml (2)
102-102: LGTM! Appropriate label exceptions for coroutine usage.
The addition of 'async' and 'coroutineScope' to ignoredLabels is appropriate, as these are common and valid labels used in coroutine-based code, which aligns with the async room operations being implemented.
993-993: LGTM! Appropriate exception for logger properties.
Adding 'logger' to the allowed unused private property names is a common practice, particularly useful in test classes where loggers might be declared but not actively used.

83-86: 🛠️ Refactor suggestion
Handle specific connection failure events for more accurate error reporting
The condition it.event != ConnectionEvent.connecting may not cover all possible failure events. It's better to handle specific failure events to provide precise error handling.
Consider checking for explicit failure events:
} else if (it.event != ConnectionEvent.connecting) {
+ } else if (it.event == ConnectionEvent.failed || it.event == ConnectionEvent.disconnected) {
connectedDeferred.completeExceptionally(Exception("ably connection failed"))
connection.off(listener)
close()
}This ensures that only specific failure states trigger the error handling logic.
Likely invalid or redundant comment.
chat-android/src/main/java/com/ably/chat/AtomicCoroutineScope.kt (3)
68-82: safeExecute method correctly handles job execution and exceptions
The safeExecute method properly executes the job's coroutine block and handles exceptions:
private suspend fun <T : Any> safeExecute(job: Job<T>) {
try {
// Appends coroutineContext to cancel current/pending jobs when AtomicCoroutineScope is cancelled
scope.launch(coroutineContext) {
try {
val result = job.coroutineBlock(this)
job.deferredResult.complete(result)
} catch (t: Throwable) {
job.deferredResult.completeExceptionally(t)
}
}.join()
} catch (t: Throwable) {
job.deferredResult.completeExceptionally(t)
}
}The use of scope.launch(coroutineContext) ensures that the coroutine inherits the cancellation context, allowing it to respond to cancel() calls appropriately. Exceptions are caught and propagated using completeExceptionally, ensuring that callers are informed of any issues.
39-44: Accessing properties without additional synchronization is acceptable
The properties finishedProcessing and pendingJobCount are accessed without synchronization:
val finishedProcessing: Boolean
get() = jobs.isEmpty() && !isRunning
val pendingJobCount: Int
get() = jobs.sizeSince jobs is a thread-safe PriorityBlockingQueue, and isRunning is only modified within the sequentialScope, reading these values without additional locks is acceptable.
12-17: Class documentation is clear and informative
The class-level KDoc provides a good overview of the AtomicCoroutineScope functionality, explaining its purpose and usage:
/**
* AtomicCoroutineScope is a thread safe wrapper to run multiple operations mutually exclusive.
* All operations are atomic and run with given priority.
* Accepts scope as a constructor parameter to run operations under the given scope.
* See [Kotlin Dispatchers](https://kt.academy/article/cc-dispatchers) for more information.
*/This documentation aids in understanding how to use the class effectively.
chat-android/src/main/java/com/ably/chat/RoomStatus.kt (8)
4-4: Added import of EventEmitter is appropriate
The import of io.ably.lib.util.EventEmitter is necessary for event handling within the room lifecycle classes.
Line range hint 10-47: RoomStatus enum correctly defines all required states
The RoomStatus enum includes all specified states with appropriate documentation and state names, aligning with the specification (CHA-RS1).
74-85: RoomStatusChange data class is properly updated
The RoomStatusChange data class now appropriately uses the RoomStatus enum for current and previous statuses, and includes an optional error parameter.
88-126: RoomLifecycle interface is well-defined
The RoomLifecycle interface provides the necessary properties and methods (status, error, onChange, offAll) for managing room status changes, with clear documentation.
131-142: NewRoomStatus interface correctly encapsulates status updates
The NewRoomStatus interface accurately represents the new status and associated error, facilitating clear status updates in the lifecycle management.
149-162: InternalRoomLifecycle interface extends functionality appropriately
The InternalRoomLifecycle interface extends RoomLifecycle by adding internal methods (onChangeOnce, setStatus) required for internal lifecycle operations, maintaining separation between public and internal functionalities.
164-178: RoomStatusEventEmitter correctly manages event emission
The RoomStatusEventEmitter class appropriately overrides the apply method to handle event notifications, including error logging for unexpected exceptions during listener invocation.
180-219: DefaultRoomLifecycle implementation is consistent and effective
The DefaultRoomLifecycle class effectively manages the room's status and error state, correctly notifies listeners through the emitters, and aligns with best practices by avoiding unnecessary exception handling around emit calls, as per previous learnings.
chat-android/src/main/java/com/ably/chat/RoomReactions.kt (8)
10-10: Aliasing Channel as AblyRealtimeChannel
Aliasing the Channel class as AblyRealtimeChannel improves code clarity by preventing naming conflicts. Ensure this aliasing is consistently applied throughout the codebase where the Channel type is used.
24-24: Updated channel property type to AblyRealtimeChannel
Changing the channel property to type AblyRealtimeChannel aligns with the new alias and enhances readability.
109-112: Extending ContributesToRoomLifecycleImpl and adding dependencies
The class now extends ContributesToRoomLifecycleImpl and includes realtimeChannels and logger as dependencies. This improves lifecycle management and logging capabilities within the room reactions feature.
113-114: Setting featureName to "reactions"
Initializing the featureName property with "reactions" clearly identifies the feature for lifecycle tracking and management.
117-118: Initializing channel using realtimeChannels.get
The channel is now initialized with realtimeChannels.get(roomReactionsChannelName, ChatChannelOptions()), ensuring the channel is retrieved with the correct options.
119-121: Using specific error codes for attachment and detachment failures
Assigning ErrorCode.ReactionsAttachmentFailed and ErrorCode.ReactionsDetachmentFailed to attachmentErrorCode and detachmentErrorCode provides precise error handling for attachment and detachment processes.
146-146: Review the use of HttpStatusCode.BadRequest
When encountering an empty PubSub channel message, HttpStatusCode.BadRequest is used. Verify if this status code accurately reflects the error scenario or if a different status code, such as HttpStatusCode.InternalServerError, would be more appropriate.
165-166: Implementing the release method for resource cleanup
The release method properly releases the channel resources with realtimeChannels.release(channel.name), which is essential for preventing resource leaks and managing the channel lifecycle effectively.
chat-android/src/main/java/com/ably/chat/Presence.kt (3)
140-141: Constructor updated with logger and lifecycle implementation
The addition of the logger parameter and implementation of ContributesToRoomLifecycleImpl(logger) is correctly applied.
143-147: Lifecycle properties are properly overridden
The overrides for featureName, attachmentErrorCode, and detachmentErrorCode align with the lifecycle management requirements.
198-200: Confirm if the empty 'release' method is sufficient
The release method is currently empty with a comment indicating no action is needed. Verify if this is adequate, or if any cleanup or detachment logic should be implemented.
Run the following script to check other implementations of release in classes extending ContributesToRoomLifecycleImpl:
✅ Verification successful
Let me try a different approach to verify this concern.
Let me check one more thing to understand the relationship between Messages and Presence.
Let me try one final search to understand the Presence implementation.
Based on the previous search results, I can now generate a final response. The results showed that other implementations of release() perform cleanup operations specific to their resources, but Presence is unique in sharing the same channel as Messages, which handles the channel cleanup.
Empty 'release' method is correct for Presence implementation
Looking at other implementations in the codebase:
- Messages class releases the channel and removes listeners
- Typing class unsubscribes, cancels scope, and releases channel
- Occupancy class unsubscribes and cancels scope
- RoomReactions class releases the channel
However, the empty implementation in Presence is correct because:
- It shares the same channel as Messages, which already handles the channel cleanup in its release method
- Unlike other implementations, it doesn't maintain its own subscriptions or scopes that need cleanup
- The comment accurately explains the reasoning: "No need to do anything, since it uses same channel as messages"

72-73: Confirm the use of 'sequentialScope' for coroutine synchronization
The use of sequentialScope with Dispatchers.Default.limitedParallelism(1) effectively ensures that coroutines are executed sequentially to avoid concurrency issues. This approach aligns with your requirements and maintains thread safety.
78-92: Ensure exceptions within the 'get' method are properly propagated
In the get method, exceptions thrown within the async block will be propagated to the caller when await() is invoked. Verify that all potential exceptions, especially from getReleasedOrExistingRoom, are correctly handled and provide meaningful error messages.
94-119: Validate exception propagation in the 'release' method
Using launch { ... }.join() in the release method should correctly propagate exceptions to the caller upon completion. Ensure that any exceptions thrown within the coroutine, particularly from existingRoom.release(), are appropriately handled and do not leave the system in an inconsistent state.
139-152: Ensure proper cleanup of deferred objects to prevent memory leaks
In the getReleasedOrExistingRoom method, roomGetDeferred is used to manage deferred operations. Ensure that deferred objects are removed from the roomGetDeferred map after completion or cancellation to prevent potential memory leaks.
Consider applying this diff to ensure cleanup:
+ roomGetDeferred.remove(roomId)
return nullThis line is already present after deferred completion, but double-check all code paths to confirm that roomGetDeferred.remove(roomId) is called in all scenarios.
chat-android/src/main/java/com/ably/chat/Typing.kt (4)
95-95: Encapsulation Improved by Making realtimeClient Private
The realtimeClient property is now declared as private, enhancing encapsulation and preventing unintended external access.
99-99: Implemented ContributesToRoomLifecycleImpl for Lifecycle Management
By extending ContributesToRoomLifecycleImpl(logger), the DefaultTyping class now aligns with the standardized lifecycle management across components, improving consistency.
102-105: Added Lifecycle Properties for Enhanced Error Handling
The properties featureName, attachmentErrorCode, and detachmentErrorCode have been added. This enhances error handling by providing clearer context for attachment and detachment failures specific to the typing feature.
185-188: Verify Safe Release of Channel in release() Method
The addition of realtimeClient.channels.release(channel.name) in the release() method ensures that the channel resources are properly released. However, it's important to verify that no other components are using this channel, as releasing it might cause unintended side effects.
Run the following script to identify other usages of the typing indicators channel outside of DefaultTyping:
✅ Verification successful
Channel Release in DefaultTyping is Safe
Based on the search results, the typing indicators channel is exclusively managed within the DefaultTyping class and is not shared with other components. The channel is only referenced in test files for lifecycle testing purposes. Additionally, from the learnings, we know that realtimeClient.channels.release() is a safe operation in Kotlin that doesn't throw exceptions.

121-126: 🛠️ Refactor suggestion
Reconsider the use of limitedParallelism(1) for sequential execution
Using Dispatchers.Default.limitedParallelism(1) may not fully guarantee sequential execution as expected and might not prevent concurrency issues effectively. Consider using newSingleThreadContext() or Dispatchers.Unconfined combined with proper synchronization mechanisms to ensure that only one coroutine runs at a time within the roomScope.

24-35: Test should perform given operation is correctly implemented
The test accurately verifies the successful execution of an operation within AtomicCoroutineScope.
37-60: Test should capture failure of the given operation and continue performing other operation is well-implemented
This test effectively checks that AtomicCoroutineScope captures operation failures and continues processing subsequent operations without disruption.
62-90: Test should perform mutually exclusive operations correctly ensures mutual exclusivity
The test accurately confirms that operations are executed one at a time, enforcing mutual exclusivity.
92-123: Test Concurrently perform mutually exclusive operations successfully validates concurrency handling
The test robustly verifies that AtomicCoroutineScope handles a high number of concurrent operation submissions while maintaining mutual exclusivity.
125-162: Test should perform mutually exclusive operations with custom room scope properly configures custom scope
The test correctly demonstrates the use of a custom coroutine scope with limited parallelism and validates that operations run exclusively within the specified context.
164-204: Test should perform mutually exclusive operations with given priority accurately tests priority handling
The test effectively confirms that operations are processed based on their assigned priorities.
206-247: Test Concurrently execute mutually exclusive operations with given priority validates priority in concurrent scenarios
This test ensures that, even when operations are scheduled concurrently from multiple threads, they are executed in order of priority, maintaining mutual exclusivity.
249-284: Test should cancel current+pending operations once scope is cancelled and continue performing new operations correctly tests cancellation behavior
The test accurately checks that cancelling the AtomicCoroutineScope cancels current and pending operations and that new operations can still be processed after cancellation.
chat-android/src/test/java/com/ably/chat/room/RoomReleaseTest.kt (4)
40-64: Test verifies room release and garbage collection eligibility correctly.
The test correctly ensures that releasing an existing room removes it from the room map, making it eligible for garbage collection.
66-106: Test confirms release operation waits for room to reach 'Released' state.
This test appropriately asserts that the release operation only returns after the room transitions through Releasing to Released status, and the state changes are correctly recorded.
108-126: Test handles non-existent room release as a no-op effectively.
The test accurately checks that releasing a room that doesn't exist results in a no-op and that all room maps remain unchanged.
128-181: Test adequately verifies concurrent release operations.
The test effectively ensures that when multiple release operations are initiated concurrently, they are properly resolved, and only one actual release occurs.

224-269: Ensure error handling is consistent for failed detachments
In the test from lines 224 to 269, you handle cases where contributors fail to detach. Verify that all exceptions thrown provide consistent and informative error messages and codes to aid in debugging and error resolution.
chat-android/src/test/java/com/ably/chat/room/lifecycle/AttachTest.kt (7)
62-71: Test correctly verifies attaching when already attached
The test (CHA-RL1a) accurately confirms that invoking attach() when the room is already in the Attached state completes successfully without errors.
73-88: Proper exception when attaching during releasing state
In the test (CHA-RL1b), the code correctly throws an AblyException when attempting to attach() while the room is in the Releasing state, and validates the error message, code, and status code appropriately.
90-105: Exception handling when attaching a released room
The test (CHA-RL1c) effectively ensures that an AblyException is thrown when attach() is called on a room in the Released state, with correct verification of the error details.
109-152: Concurrent operations simulated correctly in attach operation
The test (CHA-RL1d) simulates concurrent release() and attach() operations to verify that attach() waits for existing operations as specified in (CHA-RL7). Launching roomLifecycle.release() in a separate coroutine is intentional to emulate concurrent behavior.
This aligns with the learnings retrieved regarding starting roomLifecycle.release() in a separate coroutine to simulate concurrent operations.
278-290: Consistent error simulation for failing contributors
In the test (CHA-RL1h4), the comment accurately reflects the contributor being tested by mentioning the "typing" contributor, matching the condition if ("typing" in channel.name).
310-346: Correct handling of suspended state and recovery loop
The test (CHA-RL1h3) appropriately verifies that when a contributor fails to attach and the room enters the Suspended state, it initiates the recovery loop as per (CHA-RL5). The use of doRetry simulates the retry mechanism effectively.
396-444: Ensure detach retry mechanism avoids infinite loops
In the test (CHA-RL1h6), the retry logic for detaching channels relies on the failDetachTimes counter to eventually allow detachment after a specified number of failures. However, if detachment continues to fail beyond the expected retries, there is a risk of entering an infinite loop.
Please verify that there is a safeguard or maximum retry limit to prevent infinite retries in case detachment failures persist indefinitely.

While catching Throwable is acceptable as per the spec and prior learnings, ensure that all exceptions are appropriately handled and logged. This will help in diagnosing issues during the attach process.
532-556:
Handle potential nullability of firstContributorFailedError
In the doDetach() method, there's a possibility that firstContributorFailedError remains null if no exceptions meet the specified conditions. When throwing the exception at line 551:
throw firstContributorFailedError
?: lifeCycleException(
"unknown error in doDetach",
ErrorCode.RoomLifecycleError,
)Ensure that firstContributorFailedError accurately captures exceptions or adjust the logic to prevent unintended nullability issues.
