50-70: Consider adding edge cases for action fieldWhile the test covers the basic case, consider adding tests for:
- null action
- boundary values of action enum
72-91: Consider using parameterized tests for MessageAction valuesTo ensure comprehensive coverage of the MessageAction enum, consider using JUnit's Parameterized tests to verify serialization/deserialization of all possible action values.
Example structure:
@ParameterizedTest @EnumSource(MessageAction.class) void deserialize_message_with_different_actions(MessageAction action) { // Test implementation }
49-113: Consider additional test coverageWhile the current tests provide good coverage of the happy path and some edge cases, consider adding tests for:
- Null values for action and serial fields
- Empty or malformed serial strings
- Boundary conditions for both fields

1-1: Consider adding integer field support in serialization methods.Since this PR adds a new integer field (
serial), theBaseMessageclass should be updated to properly handle integer fields in its serialization methods:
toJsonObject: Add support for integer field serializationwriteFields: Add support for integer field serialization in MessagePack formatHere's a suggested implementation:
public static JsonObject toJsonObject(final BaseMessage message) { JsonObject json = new JsonObject(); + // Add support for integer fields + if (message instanceof Message) { + Message msg = (Message) message; + if (msg.serial != null) { + json.addProperty("serial", msg.serial); + } + } // ... existing code ... } void writeFields(MessagePacker packer) throws IOException { + // Add support for integer fields + if (this instanceof Message) { + Message msg = (Message) this; + if (msg.serial != null) { + packer.packString("serial"); + packer.packInt(msg.serial); + } + } // ... existing code ... }lib/src/main/java/io/ably/lib/types/Message.java (1)

12-14: 🛠️ Refactor suggestion
Consider enhancing the utility method.
The method has a few areas for improvement:
- The method should be
publicsince it needs to be accessed by theMessageclass for serialization/deserialization- Missing Javadoc documentation
- No validation for negative ordinals
Consider applying these improvements:
- static MessageAction tryFindByOrdinal(int ordinal) { - return values().length <= ordinal ? null: values()[ordinal]; + /** + * Attempts to find a MessageAction by its ordinal value. + * @param ordinal the ordinal value to look up + * @return the corresponding MessageAction or null if not found + */ + public static MessageAction tryFindByOrdinal(int ordinal) { + if (ordinal < 0 || ordinal >= values().length) { + return null; + } + return values()[ordinal]; + }📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements./** * Attempts to find a MessageAction by its ordinal value. * @param ordinal the ordinal value to look up * @return the corresponding MessageAction or null if not found */ public static MessageAction tryFindByOrdinal(int ordinal) { if (ordinal < 0 || ordinal >= values().length) { return null; } return values()[ordinal]; }lib/src/test/java/io/ably/lib/types/MessageTest.java (2)
57-57: 💡 Codebase verification
Serial number format should be documented in the Message class
The serial number format (
timestamp-sequence@node:version) is not documented in the codebase. While the format is being used in tests, there's no clear documentation explaining its structure and requirements. Please add JSDoc comments to theserialfield in the Message class to document:
- The format pattern:
timestamp-sequence@node:version- The purpose of each component
- Any validation requirements
🔗 Analysis chain
Verify the serial number format documentation
The serial number follows a specific format:
timestamp-sequence@node:version. Please ensure this format is documented in the Message class or relevant documentation.🏁 Scripts executed

94-113: 💡 Codebase verification
Add test cases for boundary values of MessageAction
The current test verifies behavior for action=10, but should be expanded to cover:
- Negative values (-1)
- Values at the boundary (6, 7)
- Integer.MAX_VALUE
The behavior is properly implemented in
MessageAction.tryFindByOrdinal()which returns null for any ordinal >= values().length, but this isn't documented. Add javadoc to:
- Message.action field explaining null handling for invalid values
- MessageAction.tryFindByOrdinal() documenting the null return for out-of-range values
Locations needing documentation:
- lib/src/main/java/io/ably/lib/types/Message.java: action field
- lib/src/main/java/io/ably/lib/types/MessageAction.java: tryFindByOrdinal method
🔗 Analysis chain
Enhance invalid action value testing
The test handles unknown action values well, but consider:
- Adding test cases for other invalid values (negative numbers, Integer.MAX_VALUE)
- Documenting this behavior in the Message class
Let me search for more context about the action field and its documentation.
Let me check the MessageAction enum to understand the valid action values and their documentation.
Let me check the content of the MessageAction enum file to understand the implementation.

50-70: Consider adding more test cases for serialization.While the test covers the basic serialization case, consider adding the following test cases for better coverage:
- Different MessageAction values
- Null/empty serial numbers
- Invalid serial number formats
Here's a suggested additional test:
@Test public void serialize_message_with_null_fields() { Message message = new Message("test-name", "test-data"); message.action = null; message.serial = null; JsonElement serializedElement = serializer.serialize(message, null, null); JsonObject serializedObject = serializedElement.getAsJsonObject(); assertNull(serializedObject.get("action")); assertNull(serializedObject.get("serial")); }
94-113: Enhance error handling test coverage.While the test verifies handling of one unknown action value, consider adding tests for:
- Negative action values
- Action values at type boundaries (Integer.MAX_VALUE)
- Invalid data types for action (string, boolean)
Here's a suggested additional test:
@Test public void deserialize_message_with_invalid_action_type() throws Exception { JsonObject jsonObject = new JsonObject(); jsonObject.addProperty("clientId", "test-client-id"); jsonObject.addProperty("action", "invalid_string"); // Invalid type Message message = Message.fromEncoded(jsonObject, new ChannelOptions()); assertNull(message.action); }lib/src/main/java/io/ably/lib/types/Message.java (1)

1-411: Consider versioning strategy for MessageActionWhile the implementation is solid, consider these architectural points:
- Document the stability guarantee for MessageAction ordinals
- Consider adding a version field to the wire protocol to handle future enum extensions
- Consider using string representations instead of ordinals for better forward compatibility

72-91: Document the serial number format requirements.
The test uses a specific format for the serial number (01826232498871-001@abcdefghij:001), which appears to contain timestamp and sequence information. This format should be documented and validated.
Let's check if there's any documentation about the serial number format:
Consider adding a comment explaining the serial number format and its components:
@Test
public void deserialize_message_with_serial() throws Exception {
+ // Serial number format: <timestamp>-<sequence>@<connection-id>:<message-sequence>
// Given
JsonObject jsonObject = new JsonObject();lib/src/main/java/io/ably/lib/types/Message.java (5)
49-69: LGTM! Well-documented field additions
The new fields are thoroughly documented with clear specifications and initialization requirements. The documentation effectively explains the complex logic for version field initialization.
360-364: LGTM! Clean JSON deserialization implementation
The implementation properly handles null values and uses appropriate helper methods for type conversion.
198-203: Consider handling invalid action ordinals
The tryFindByOrdinal result should be validated as it might return null for invalid ordinals.
Let's check the implementation of tryFindByOrdinal:
380-388: Verify test coverage for serialization edge cases
The serialization logic looks correct, but we should ensure comprehensive test coverage for various combinations of null and non-null values.
Let's check for existing tests:
✅ Verification successful
Test coverage for serialization is adequate
The test coverage for the serialization of serial, version, and action fields is well implemented in MessageTest.java. Specifically:
- Test case
serialize_message_with_serialverifies serialization ofserialandactionfields - Both positive and negative test cases exist for
actionfield (including unknown action values) - Null checks are implicitly tested through
serialize_message_with_name_and_datawhich verifies optional fields are not included when null

56-59: Enhance documentation for theactionfieldThe documentation for the
actionfield is minimal. Consider adding details about:
- The purpose of this field
- Possible values from MessageAction enum
- When this field is expected to be set/used
162-164: Consider using a more stable enum serialization approachUsing
ordinal()for enum serialization is risky as it depends on the enum declaration order. If theMessageActionenum is modified in the future (reordering, inserting new values), it could break message compatibility.Consider using:
- A string representation of the enum value, or
- A dedicated numeric value that doesn't depend on declaration order
345-347: Consider validating the serial field formatThe
serialfield is read without any validation. If there are expectations about its format (e.g., length, character set), consider adding validation to ensure data integrity.
49-60: Consider adding unit tests for new fieldsThe implementation of the new
serialandactionfields appears complete with proper serialization/deserialization support. To ensure robustness, consider adding unit tests for:
- Serialization/deserialization of both fields in various formats (Msgpack, JSON)
- Edge cases (null values, invalid action ordinals)
- Serial field format validation
- Backward compatibility with messages lacking these fields
Would you like me to help generate comprehensive unit tests for these scenarios?

184-187: Verify error handling for invalid action values
Please ensure that MessageAction.tryFindByOrdinal() properly handles invalid ordinal values. Consider:
- What happens if the ordinal is out of range?
- Should we log a warning when an invalid action is encountered?
✅ Verification successful
Let me try a different approach to find the implementation of MessageAction.tryFindByOrdinal.
Error handling for invalid action values is properly implemented
The MessageAction.tryFindByOrdinal() implementation safely handles invalid ordinal values by:
- Returning
nullfor out-of-range ordinals (when ordinal >= values length) - Safely accessing valid ordinals through the enum's
values()array
The calling code in Message.java also properly handles null actions, and there's already logging in place for unexpected fields. No additional error handling is needed.

Related to https://github.com/ably/specification/pull/210/files and https://github.com/ably/specification/pull/235/files.
I'm not sure why we didn't address other materialization fields as a part of this PR
e.g. as per TM2k
@(TM2k)@ @serial@ string - an opaque string that uniquely identifies the message. If a message received from Ably (whether over realtime or REST, eg history) with an @action@ of @MESSAGE_CREATE@ does not contain a @serial@, the SDK must set it equal to its @TM2p@ @version@
Seems TM2p version field is missing
|
It requires some thinking, more tests and it will be better to implement as part of separate PR |

Sure, but the spec says |

The code references MessageAction enum but its implementation is not visible in the provided context. We should verify:
- The enum implementation includes all required action types
- The impact of these changes on message handling throughout the SDK
Let's verify the MessageAction enum implementation and its usage:
✅ Verification successful
Let's gather more information about the MessageAction enum definition since it wasn't found in the previous search:
MessageAction enum implementation is complete and properly used
The MessageAction enum is well-defined in lib/src/main/java/io/ably/lib/types/MessageAction.java with all required action types:
- MESSAGE_UNSET (0)
- MESSAGE_CREATE (1)
- MESSAGE_UPDATE (2)
- MESSAGE_DELETE (3)
- ANNOTATION_CREATE (4)
- ANNOTATION_DELETE (5)
- META_OCCUPANCY (6)

- Deserialization via
tryFindByOrdinal - Message creation and validation in tests
- Handling message serials with MESSAGE_CREATE action

However, consider:
- Adding validation for channelSerial format
- Handling cases where messageIndex exceeds 999 to prevent format issues

49-113: Past comment about version field tests is no longer applicable.
According to the PR objectives, the version field was intentionally removed to focus on essential fields for Chat Beta. The existing test coverage for action and serial fields aligns with the current implementation scope.
lib/src/main/java/io/ably/lib/types/Message.java (1)
49-76: Field declarations look good, except for the version field
The field declarations and documentation for serial, action, and createdAt are well-implemented and properly documented with their respective spec references (TM2k, TM2j, TM2o).
The version field and its documentation should be removed as discussed in the PR objectives.
lib/src/test/java/io/ably/lib/test/realtime/RealtimeMessageTest.java (1)
982-996: LGTM! Well-structured test setup and assertions.
The test method effectively validates the new message fields and their expected values. The assertions are comprehensive and cover all the required fields: serial, version, createdAt, action, and message format.

851-851:
Ensure createdAt is only set if not provided by server
The current implementation always overwrites createdAt with timestamp. According to TM2o spec and the previous review comment, we should only set it if not provided by the server.
Apply this diff to fix the issue:
-if(msg.createdAt == null) msg.createdAt = msg.timestamp;
+if(msg.createdAt == null) msg.createdAt = msg.timestamp;Likely invalid or redundant comment.

23-25: Verify the security implications of wildcard permissions
The new capability grants unrestricted access (*) to all channels in all namespaces ([*]*). While this is acceptable for testing purposes, we should ensure this configuration is only used in test environments.
✅ Verification successful
Wildcard permissions are safely confined to test environment
The verification confirms that:
- The wildcard capability pattern
[*]*with*permissions only exists intestAppSpec.json - This file is exclusively used in test contexts:
- Located in
test/resources/local/directory - Only referenced by test setup code (
Setup.java) and test build script - No usage found in production or example code
- Located in
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify that this wildcard capability is only used in test configurations
# and not in production code or examples
# Check if similar wildcard patterns exist in non-test files
rg -g '!test*' -g '!*.test.*' -l '\[\*\]\*.*\*'
# Check if this file is referenced outside of test code
rg -g '!test*' -g '!*.test.*' 'testAppSpec.json'
Length of output: 98
Script:
#!/bin/bash
# Let's try a different approach to verify the security implications:
# 1. Find all JSON files that might contain capability configurations
fd -e json
# 2. Search for wildcard patterns in all JSON files
rg -t json '\[\*\]\*.*\*' -C 2
# 3. Check if testAppSpec.json is referenced anywhere in the codebase

94-113: Address integration testing requirements.
While this unit test properly handles unknown actions, there are two pending items from the PR discussion:
- Integration tests for inbound message handling were requested
- If version field is planned for future implementation, we should document this requirement
Let's check if there are any existing integration tests:
Consider creating a separate integration test class (e.g., MessageIntegrationTest) to verify the end-to-end behavior of these fields in a real connection scenario.
