feat: Implement logging for Room, RoomLifecycleManager #84
Conversation
WalkthroughThe pull request introduces several modifications across various classes related to messaging, occupancy, presence, and room management in the chat application. Key changes include the renaming of logging properties for consistency, enhancements to error handling and logging mechanisms, and updates to method signatures to incorporate logging parameters. The overall structure of the interfaces remains intact, but the internal implementations have been refined to improve clarity and traceability during operations. Changes

Learning: In `chat-android/src/main/java/com/ably/chat/Occupancy.kt`, within the `DefaultOccupancy` class, when methods use `room.chatApi`, which utilizes the REST API, there's no need to call `room.ensureAttached()` before performing the operation.

chat-android/src/main/java/com/ably/chat/RoomReactions.kt (2)
109-109: LGTM: Logger implementation looks good!
The logger is properly initialized and scoped with the "Reactions" context tag, following good logging practices. The inheritance from ContributesToRoomLifecycleImpl ensures proper lifecycle management.
Also applies to: 121-121
140-141: Please clarify the TODO comment about potential spec changes
The TODO comment indicates that the ensureAttached check might be removed, but lacks context about:
- Which core spec change might trigger this
- The implications of removing this check
- The timeline or conditions for removal
Consider adding more detailed documentation about:
- The current purpose of this check
- Why it might become unnecessary
- What spec changes would trigger its removal
Let's check for related TODOs or spec discussions:
chat-android/src/main/java/com/ably/chat/Typing.kt (3)
97-97: LGTM: Well-structured logging initialization
The logger setup follows best practices by:
- Using the room's logger as the base logger
- Adding appropriate context with the "Typing" tag for better log filtering
- Maintaining consistency with other components in the codebase
Also applies to: 106-106
173-175: LGTM: Well-structured typing start implementation
The implementation properly handles:
- Logging during room attachment
- Timer reset logic
- Presence channel updates
Line range hint 97-106: Verify logging configuration consistency
Let's verify that the logging configuration is consistent across related components.
✅ Verification successful
Logging configuration is consistently implemented across components
The verification shows consistent logging patterns across all major components:
- All components initialize their loggers using
room.logger.withContextwith appropriate component tags - The
ensureAttachedmethod consistently receives the logger parameter across all usages - Each component maintains its own scoped logger with a descriptive tag matching its functionality

126-127: LGTM! Clear and accurate assertions.
The assertions correctly verify that no release operations are in progress by checking both the size and specific room entry in the RoomReleaseDeferredMap.
188-189: LGTM! Proper verification of release operation state.
The assertions correctly verify that a release operation is in progress by checking both the map size and the presence of a deferred entry for the specific room.
192-194: LGTM! Proper verification of concurrent get operation state.
The assertions correctly verify that a get operation is waiting by checking both the map size and the presence of a deferred entry for the specific room.
199-200: LGTM! Proper verification of completed release operation.
The assertions correctly verify that the release operation has completed by checking that the map is empty and the specific room entry is removed.
203-205: LGTM! Proper verification of completed get operation.
The assertions correctly verify that the get operation has completed by checking that the map is empty and the specific room entry is removed.
chat-android/src/test/java/com/ably/chat/room/RoomReleaseTest.kt (5)
117-118: LGTM! Proper verification of initial state.
The assertions correctly verify that both maps are empty before attempting to release a non-existent room.
124-125: LGTM! Proper verification of unchanged state after no-op.
The assertions correctly verify that both maps remain empty after attempting to release a non-existent room.
167-168: LGTM! Proper verification of release operation state.
The assertions correctly verify that a release operation is in progress by checking both the map size and the presence of a deferred entry.
175-175: LGTM! Proper verification of completed release operation.
The assertion correctly verifies that the release operation has completed by checking that the map is empty.
226-227: LGTM! Comprehensive verification of concurrent operations.
The assertions thoroughly verify the state transitions during concurrent get and release operations:
- Initial release operation state
- Waiting get operations state
- Cancellation of pending get operations
- New get operation state
- Final cleanup of both maps
The test provides excellent coverage of the concurrent operation handling.

chat-android/src/test/java/com/ably/chat/room/RoomTestHelpers.kt (1)
69-70: LGTM! Property names are now more descriptive
The renaming of properties from RoomGetDeferred/RoomReleaseDeferred to RoomGetDeferredMap/RoomReleaseDeferredMap better reflects their nature as map collections, improving code clarity.
chat-android/src/main/java/com/ably/chat/Rooms.kt (4)
65-65: LGTM! Proper logger initialization with context
Good practice to use a context-specific logger with the "Rooms" tag for better log filtering and identification.
Also applies to: 67-67
76-77: LGTM! Consistent property naming
Property names now clearly indicate they are maps, matching the changes in test helpers.
80-80: LGTM! Well-structured logging in get method

Also applies to: 84-84
Line range hint 88-93: Appropriate usage of room.chatApi without ensuring attachment
Following prior learnings, the get() method correctly uses room.chatApi without calling room.ensureAttached(), as the REST API does not require the room to be attached.

The trace logging for attach, detach, and release methods improves debugging capabilities.
Also applies to: 232-232, 241-241
Line range hint 251-296: LGTM! Enhanced error tracking in ensureAttached.
The ensureAttached method changes provide:
- Improved error tracking with feature-specific logger
- Clear state transition logging
- Detailed error information when attachment fails
chat-android/src/main/java/com/ably/chat/Messages.kt (2)
223-223: LGTM: Proper integration with room lifecycle logging
The inheritance from ContributesToRoomLifecycleImpl with room.logger parameter ensures consistent logging across the room lifecycle, aligning with the PR's logging implementation objectives.
229-229: LGTM: Well-structured logger initialization with proper context
The logger is correctly initialized with the "Messages" tag and properly scoped from the room's logger.
Let's verify consistent logger usage across the codebase:
✅ Verification successful
LGTM: Logger initialization follows consistent pattern across the codebase
The verification confirms that the logger initialization in Messages.kt follows the same pattern used consistently throughout the codebase. All components (Typing, Rooms, Reactions, Messages, Presence, Occupancy, ChatClient) properly initialize their loggers using withContext(tag = "...") with appropriate context tags.

102-102: Consider improving log format for better parsability.The current format
"$currentTime (${level.name.uppercase()}) ${finalContext.tag}:${message}$contextString"could be enhanced for better machine parsing and readability.Consider using a more structured format with clear separators:
-val formattedMessage = "$currentTime (${level.name.uppercase()}) ${finalContext.tag}:${message}$contextString" +val formattedMessage = buildString { + append(currentTime) + append(" | ") + append(level.name.uppercase()) + append(" | ") + append(finalContext.tag) + append(" | ") + append(message) + if (completeContext.isNotEmpty()) { + append(" | context=") + append(completeContext) + } +}Benefits:
- Uses pipe (
|) as a consistent separator- Avoids confusion with colons in timestamps
- Only includes context when non-empty
- Easier to parse programmatically using split operations
97-102: Consider documenting the logging format specification.As these changes are part of a broader logging standardization effort across the application, it would be valuable to document the logging format specification (including the tag prefix and message structure) in a central location, such as a README or documentation file.
This documentation would help:
- Ensure consistency as the application grows
- Guide future contributors
- Assist in creating log parsing tools
- Make log analysis more efficient
