37-55: Address the TODOs regarding status code mappingsThe
statusCodeproperty currently includes TODO comments indicating that the status codes are guesses and need revisiting once the specification questions are resolved. Finalizing these status codes based on the latest specification is crucial for accurate error handling.Would you like assistance in updating these status codes according to the latest specification, or should we open a GitHub issue to track this task?
187-190: Document the use ofNSUnderlyingErrorKeyfor error causationThe TODO comment suggests that using
NSUnderlyingErrorKeyto populatecausemight be an implementation detail. It's important to document this behavior to clarify how thecauseis set inARTErrorInfo.Shall I assist in drafting documentation for this behavior or open a GitHub issue to ensure it is addressed?
Sources/AblyChat/RoomLifecycleManager.swift (2)
117-118: Implement asynchronous behavior as per CHA-RL1h5The TODO comment indicates that the asynchronous aspect of CHA-RL1h5 is yet to be implemented. This is important for proper adherence to the room lifecycle specification.
Would you like assistance in implementing the asynchronous behavior as per the specification, or should we open a GitHub issue to track this task?
205-205: Determine the correct wait time for retriesThe TODO comment questions the appropriate wait time before retrying detach operations. Defining an optimal retry interval is important to balance performance and resource utilization.
Shall I help in determining the suitable wait time based on best practices or the latest specification, or should we open a GitHub issue to address this?
Tests/AblyChatTests/RoomLifecycleManagerTests.swift (2)
487-487: Clarify error source in detachment failure testThe TODO comment raises a question about whether to use
errorReasonor the error thrown by the contributor'sdetachcall. Resolving this is important for accurate testing of error handling.Would you like assistance in determining the correct error source according to the specification for this test case, or should we open a GitHub issue to track this question?
503-504: Address the untested spec point CHA-RL2h2The comment indicates difficulty in testing the specification point CHA-RL2h2 due to concurrency issues. It's important to find a way to test this to ensure full coverage.
Can I help devise a testing strategy to cover this spec point, perhaps by using synchronization primitives or mock objects to control concurrency, or should we open a GitHub issue to address this challenge?

Let's verify the expected behavior according to the specification. Based on CHA-RL3f, it's important to confirm whether the wait time applies in this scenario.
Would you like me to research the specification further to clarify this point, or should we open a GitHub issue to resolve this ambiguity?

168-222: Possible Unhandled Errors During Detach OperationIn the
performDetachOperationmethod, errors from detaching contributors are accumulated, but the loop continues without handling non-fatal errors immediately. This could lead to multiple errors being thrown, potentially obscuring the root cause.Consider collecting all errors and providing a comprehensive summary after attempting to detach all contributors. Alternatively, handle critical errors promptly if they should halt the detachment process.
246-269: Potential Infinite Loop Without Cancellation HandlingIn the
performReleaseOperationmethod, thedetachLoopcontinues indefinitely until the contributor is successfully detached. If the task is cancelled, this loop may prevent the task from terminating properly, potentially leading to resource leaks or unresponsive behavior.Consider adding a check for task cancellation within the loop to handle cancellations gracefully:
detachLoop: while true { let contributorState = await contributor.channel.state // CHA-RL3e guard contributorState != .failed else { logger.log(message: "Contributor \(contributor) is FAILED; skipping detach", level: .info) break } logger.log(message: "Detaching contributor \(contributor)", level: .info) do { try await contributor.channel.detach() break detachLoop } catch { // CHA-RL3f: Retry until detach succeeds, with a pause before each attempt logger.log(message: "Failed to detach contributor \(contributor), error \(error). Will retry in 1s.", level: .info) + if Task.isCancelled { + logger.log(message: "Task was cancelled during detach operation.", level: .info) + return + } // TODO: Make this not trap in the case where the Task is cancelled (as part of the broader https://github.com/ably-labs/ably-chat-swift/issues/29 for handling task cancellation) // TODO: what's the correct wait time? (https://github.com/ably/specification/pull/200#discussion_r1763822207) // swiftlint:disable:next force_try try! await clock.sleep(nanoseconds: 1_000_000_000) // Loop repeats } }Since this change relates to handling task cancellations, verify that the cancellation behavior aligns with the expected operation. Ensure that the task responds appropriately when cancellation is requested.

37-55: Status codes look good for detachment failures and room state errors, but reconsider for attachment failures.
- Using 400 for detachment failures and room state errors seems appropriate as they likely indicate client errors.
- For attachment failures, consider using 4xx status codes if the failure is due to client error. 500 should be reserved for server-side issues.
187-190: Good update to populate thecauseproperty fromchatError.cause.This enhances error reporting by providing the underlying error.

31-73: Excellent addition of testing guidelines!The new testing guidelines introduce a structured approach to attributing tests to spec points using the
@spec,@specOneOf,@specPartial, and@specUntestedtags. This enhances the clarity and organization of the test suite, making it easier to track test coverage and identify gaps in the implementation of the feature spec.The code examples provided are clear and demonstrate the usage of the tags effectively. The requirement for an explanation when using the
@specUntestedtag ensures that the absence of tests is justified, promoting a disciplined approach to testing.These changes will greatly improve the maintainability and documentation of the test suite, ensuring that tests are well-aligned with the specifications.

19-23: Excellent addition of granular error codes for attachment failures!The new error codes provide a clean way to distinguish attachment failures for different room features. The chosen naming convention and error code range are very appropriate.
25-29: Great job adding granular error codes for detachment failures!The new error codes provide a clean way to distinguish detachment failures for different room features. The naming convention is consistent with the attachment failure codes, and the chosen error code range provides a clear separation.
31-33: Nice addition of error codes for room state errors!The new error codes cover critical room states that could lead to errors. The naming is clear, and the error code range is distinct from other error categories.
67-175: Excellent enhancements to theChatErrorenum for better error handling and reporting!
- The new
attachmentFailedanddetachmentFailedcases, along with the associatedcode,localizedDescription, andcauseproperties, significantly improve the error handling and reporting capabilities.- Mapping the
ChatErrorcases to appropriateErrorCodevalues in thecodeproperty is spot on.- The
localizedDescriptionproperty, with the help of the new helper method, constructs very clear and contextual error messages.- Returning the underlying error in the
causeproperty for attachment and detachment failures is a great addition for better error reporting.Sources/AblyChat/RoomLifecycleManager.swift (6)
3-15: Async methods and state inRoomLifecycleContributorChannelprotocolThe use of async methods for
attachanddetachinstead of callbacks is a good design choice. It makes it easier to create mocks for testing, as the type system can ensure that the callbacks areSendable.Marking the channel's mutable state as
asyncis a clever way to highlight the possibility of concurrent modifications from a separate thread. While it doesn't solve concurrency issues, it makes them more visible to the caller.The TODO comment indicates that the resolution of these concurrency issues will be tracked in a separate issue, which is a good approach.
17-274:RoomLifecycleManageractor designThe use of an actor for encapsulating the lifecycle management logic and state is a good design choice. It ensures thread safety and consistency by protecting the internal state and providing a clear interface for interacting with the lifecycle manager.
The generic
Channeltype parameter constrained to theRoomLifecycleContributorChannelprotocol allows for flexibility and testability. It enables the use of different channel implementations, including mocks for testing purposes.Marking the
currentanderrorproperties asinternal private(set)is a good practice. It ensures that these properties can only be modified within the actor, maintaining the integrity of the lifecycle state.The
onChangemethod provides a convenient way for subscribers to react to room status changes. This is useful for updating the UI or performing other actions based on lifecycle events.The
changeStatusandemitStatusChangemethods encapsulate the logic for updating the current state and notifying subscribers. This promotes code reuse and maintainability by centralizing the state management logic.Overall, the
RoomLifecycleManageractor is well-designed and follows good practices for managing the lifecycle of real-time chat room contributors.
19-24:Contributorstruct designThe
Contributorstruct provides a clean and concise way to encapsulate the contributor's feature and channel. It keeps the related data together and makes it easy to pass around the contributor information.The
featureproperty is a nice touch for providing context when throwing errors related to contributor operations. It allows for more specific error messages that indicate which feature encountered an issue.The
channelproperty's type is constrained by the generic type parameter of theRoomLifecycleManageractor. This ensures that the channel conforms to theRoomLifecycleContributorChannelprotocol, providing a consistent interface for interacting with the contributor's channel.Overall, the
Contributorstruct is a well-designed and purposeful addition to theRoomLifecycleManageractor.
71-130:performAttachOperationmethod implementationThe
performAttachOperationmethod closely follows the CHA-RL1 specification for theATTACHoperation. It correctly implements the required state transitions and error handling based on the current state and the result of attaching the contributors.The use of a
switchstatement to handle different current states is a clear and concise way to implement the state-based behavior. It makes the code readable and easy to understand.The method includes informative logging messages at key points, such as when attaching a contributor or handling a failed attachment. These messages are helpful for debugging and understanding the lifecycle flow.
The error handling for failed contributor attachments is comprehensive and follows the specification rules. It takes into account the contributor's state and throws the appropriate errors based on the specification.
The TODO comment indicates that the asynchronous part of CHA-RL1h5 needs to be implemented, and it is tracked in a separate issue. This is a good practice for keeping the code maintainable and ensuring that the remaining work is not forgotten.
Overall, the
performAttachOperationmethod is well-implemented and adheres to the CHA-RL1 specification.
149-226:performDetachOperationmethod implementationThe
performDetachOperationmethod closely follows the CHA-RL2 specification for theDETACHoperation. It correctly implements the required state transitions and error handling based on the current state and the result of detaching the contributors.The use of a
switchstatement to handle different current states is a clear and concise way to implement the state-based behavior. It makes the code readable and easy to understand.The method includes informative logging messages at key points, such as when detaching a contributor or handling a failed detachment. These messages are helpful for debugging and understanding the lifecycle flow.
The error handling for failed contributor detachments is comprehensive and follows the specification rules. It takes into account the contributor's state and handles the errors accordingly, such as storing the first detach error to be thrown later and transitioning to the
failedstate if necessary.The retry logic for non-failed contributors is implemented as per the specification, with a pause between each attempt. This ensures that the detachment is retried until it succeeds, as required by the specification.
The TODO comment indicates that the correct wait time for the retry pause needs to be determined, and it is tracked in a separate discussion. This is a good practice for keeping the code maintainable and ensuring that the remaining work is not forgotten.
Overall, the
performDetachOperationmethod is well-implemented and adheres to the CHA-RL2 specification.
228-273:performReleaseOperationmethod implementationThe
performReleaseOperationmethod closely follows the CHA-RL3 specification for theRELEASEoperation. It correctly implements the required state transitions and contributor detachment logic based on the current state.The use of a
switchstatement to handle different current states is a clear and concise way to implement the state-based behavior. It makes the code readable and easy to understand.The method includes informative logging messages at key points, such as when skipping a failed contributor or retrying a detachment.

45-67: LGTM: Comprehensive examples and future plansThe additional details and examples effectively illustrate the proper use of each tag. The mention of the future script (issue #46) provides valuable context for the purpose of these tags in generating reports on spec implementation coverage.
Suggestion: Consider adding a brief note about the importance of keeping these tags up-to-date as the codebase evolves, to ensure the accuracy of the generated reports.

19-33: LGTM! Consider adding comments for new error codes.The new error codes for attachment/detachment failures and room state errors are well-organized and align with the PR objectives. They follow a consistent naming convention and numbering scheme.
Consider adding brief comments for each new error code to explain their purpose, similar to the existing comment for
inconsistentRoomOptions. This would improve code documentation and make it easier for other developers to understand the purpose of each error code.
37-55: LGTM! Consider tracking the TODO comment.The
statusCodeproperty has been updated correctly to include the new error cases. The assignment of HTTP status codes (400 and 500) for different error types is logical.The TODO comment indicates that the status codes are currently a best guess and may need revision once the specification question is answered. To ensure this is not overlooked, would you like me to create a GitHub issue to track this TODO and link it to the specification question (ably/specification#200 (comment))?
114-162: LGTM! Consider using string interpolation for better readability.The new helper method
localizedDescription(forFailureOfOperation:feature:)and the updatedlocalizedDescriptionproperty greatly improve the error message generation. The implementation is clean, reusable, and follows Swift best practices.Consider using string interpolation for the error messages in the
localizedDescriptionproperty to improve readability. For example:case .roomInFailedState: "Cannot perform operation because the room is in a failed state."Could be written as:
case .roomInFailedState: "Cannot perform operation because the room is in a \(self) state."This would make it easier to maintain consistent wording across similar error messages.

165-190: LGTM! Consider tracking the TODO comment about documentation.The new
causeproperty inChatErrorand its integration into theARTErrorInfoextension are well-implemented. This change improves error reporting by including underlying error information for attachment and detachment failures.The TODO comment suggests documenting the use of
NSUnderlyingErrorKeyin ably-cocoa. To ensure this documentation task is not overlooked, would you like me to create a GitHub issue to track this TODO and link it to the mentioned issue (#32)?

The three types of tags (@SPEC, @specOneOf, and @specPartial) offer flexibility in describing test coverage, and the examples are particularly helpful for understanding the usage of each tag.
One minor suggestion for improvement:
Consider adding a brief explanation of why attributing tests to spec points is important at the beginning of the section. This could help motivate developers to follow these guidelines consistently.You could add a brief introductory sentence like:

69-73: LGTM! Clear guidelines for marking untested spec points.The introduction of the @specUntested tag is a valuable addition to the testing guidelines. It provides a way to acknowledge implemented spec points that cannot be automatically tested, ensuring comprehensive tracking of the specification implementation. The emphasis on sparing use and the requirement for an explanation are appropriate safeguards against overuse.
75-79: LGTM! Excellent example of @specUntested usage.The provided example effectively demonstrates the proper use of the @specUntested tag. The explanation is thorough and clearly justifies why the spec point cannot be tested automatically. This example will be valuable for developers in understanding when and how to use this tag appropriately.

56-88: Comprehensive test attribution guidelinesThe new section on attributing tests to spec points is well-structured and provides clear guidance for developers. The three types of tags (@SPEC, @specOneOf, and @specPartial) offer flexibility in describing test coverage. The examples are particularly helpful for understanding the usage of each tag.
To further enhance this section, consider adding a brief note about the importance of consistent tag usage across the test suite. For example:
In [#46](https://github.com/ably-labs/ably-chat-swift/issues/46), we'll write a script that uses these tags to generate a report about how much of the feature spec we've implemented. + +Consistent use of these tags across the test suite is crucial for accurate reporting and maintaining a clear overview of our test coverage relative to the specification.🧰 Tools

90-100: Valuable addition for tracking untested spec pointsThe introduction of the @specUntested tag is a great way to maintain transparency about test coverage. It provides a structured way to acknowledge implemented spec points that cannot be automatically tested, ensuring comprehensive tracking of the specification implementation.
To further strengthen this practice, consider adding a guideline to periodically review @specUntested items. For example:
// @specUntested CHA-EX2b - I was unable to find a way to test this spec point in an environment in which concurrency is being used; there is no obvious moment at which to stop observing the emitted state changes in order to be sure that FAILED has not been emitted twice.
+It's recommended to periodically review @specUntested items to determine if new testing strategies or tools have become available that might allow for automated testing of these spec points.
--- `62-62`: **Correct usage of "different to" in British English** The phrase "different to" in this line is correct according to British English conventions, which this project follows. To prevent future false positives from static analysis tools, consider adding a comment to explicitly indicate the use of British English. For example: ```diff - This is different to `@specOneOf` in that it implies that the test suite does not fully test this spec item. + This is different to `@specOneOf` in that it implies that the test suite does not fully test this spec item. // Using British English conventionThis comment will help other contributors understand the intentional use of British English and can be used to configure language-specific linting rules if needed in the future.

This is based on [1] at b4a495e. It’s generated some questions, which I’ve asked on that PR. Note that the spec has been through a few revisions since I started implementing this; I’ve tried to keep everything in sync but some older stuff might still be accidentally there. I’ve implemented most of the specified behaviour for the ATTACH, DETACH, and RELEASE operations. I have not yet implemented RETRY since it’s quite different to those three and I wanted to get eyes on this first chunk of work; have created #51 for implementing it. Of the operations that I have implemented, I have not implemented the following (this is accurately reflected by the @SPEC… tags in the tests): - Lifecycle behaviour that relates to another ongoing operation (created #52) - Lifecycle behaviour relating to “transient disconnect timeouts” (created #48) - Lifecycle behaviour that occurs “asynchronously” outside an operation (created #50) - CHA-RL1g2, which refers to emitting “discontinuity events” which are a concept not yet implemented; this will come in #53. The room lifecycle manager introduced by this commit is currently a standalone object, which is not integrated with the rest of the SDK. I’ve created #47 for doing this integration work. The @SPEC… tags are based on the on the JS rules [2] @ 8c9ce8b, but I camel-cased them and also decided that: - if a test doesn't relate to a spec point, it doesn't need any markers - there should be a way to know that a spec point is tested across multiple tests - there should be a way of marking a spec point as implemented but not tested (so that can show up differently in reporting; important given that we’re also going to use this report as a to-do list of what still needs to be implemented) Part of #28.
