1064-1064: Deprecation Warning Version Number May Be OutdatedThe deprecation warning in the
match_legacymethod mentions removal inovos-core 0.1.0, which might already have been released. Consider updating the version number to reflect the accurate future version when this method will be removed.

4-4: LGTM: Import addition aligns with session context handling.
The addition of dig_for_message import supports the PR's objective of maintaining message context for session handling.
81-82: LGTM: Message context propagation with a thread-safety consideration.
The message context is correctly propagated to send_query. However, there's a potential thread-safety issue with the self.waiting flag, which could lead to race conditions if multiple searches are performed concurrently.
Let's verify if concurrent searches are possible in the codebase:
Consider using a threading.Event or similar synchronization primitive instead of a boolean flag for thread-safe operation:
from threading import Event
# In __init__
self.waiting = Event()
# In search method
self.waiting.set()
while self.waiting.is_set() and time.time() - start_ts <= timeout:
time.sleep(0.2)
self.waiting.clear()✅ Verification successful
Thread safety concern is valid but low risk in current implementation
The code review's thread safety concern is valid but the actual risk is low in the current implementation because:
- The
waitingflag is only used within thesearchmethod as a timeout mechanism - The results collection happens through message passing via the bus system
- Each search query maintains separate result collections in dictionaries keyed by phrase:
self.query_replies[phrase]self.query_extensions[phrase]
While using an Event would be a cleaner implementation, the current code is functionally safe because:
- Results are isolated by search phrase
- The waiting flag only affects timeout behavior
- The bus message handling is thread-safe by design
The suggested improvement would be an enhancement rather than fixing a critical issue.

70-74: LGTM: Robust message context handling implementation.
The implementation properly maintains message context through the following mechanisms:
- Accepts an optional message parameter
- Uses a fallback chain (provided -> dig_for_message -> empty)
- Forwards context when emitting the query
Let's verify the message context preservation pattern is consistent across the codebase:
✅ Verification successful
Let's search for these message handling patterns to verify the consistency across the codebase. The previous search might have failed due to case sensitivity or incomplete pattern matching.
Message context preservation pattern is consistently implemented
The verification confirms that the message context preservation pattern is consistently implemented across the codebase:
dig_for_message()is used consistently as a fallback in bothlegacy.pyandopm.pywith the same pattern:message or dig_for_message() or Message("")- Message forwarding via
message.forward()is used consistently throughout the codebase for maintaining context in message bus communications - The pattern of preserving message context is uniform across different event handlers and message processing functions
The implementation in send_query follows the established pattern in the codebase and maintains message context appropriately.

17-17: Import Statement Updated Correctly
The import statement now includes IntentHandlerMatch and ConfidenceMatcherPipeline from ovos_plugin_manager.templates.pipeline, which are necessary for handling intent matches and confidence levels.
1073-1073: Inheritance Structure Adjusted for MycroftCPSLegacyPipeline
The MycroftCPSLegacyPipeline class now correctly inherits from both ConfidenceMatcherPipeline and OVOSAbstractApplication, ensuring it has access to necessary methods and properties from both parent classes.
1076-1078: Superclasses Initialized Properly in __init__ Method
The __init__ method correctly initializes both parent classes:
- Calls
OVOSAbstractApplication.__init__with appropriate parameters. - Calls
ConfidenceMatcherPipeline.__init__to ensure proper setup.
1081-1081: Event Handler Registration Confirmed
An event handler for "ocp:legacy_cps" is registered with the handle_legacy_cps method, marked as an intent handler. Ensure that handle_legacy_cps is implemented correctly to handle legacy CPS intents.
1085-1085: Override of match Method Ensures Proper Intent Matching
The match method is overridden in MycroftCPSLegacyPipeline to match legacy Mycroft CommonPlay skills when legacy_cps is enabled in the configuration. This allows for compatibility with legacy skills.
1108-1112: Correct Construction of IntentHandlerMatch Object
The IntentHandlerMatch is created with:
match_typeset to"ocp:legacy_cps".match_datacontaining the query and confidence level.skill_idset toOCP_ID.utterancepassed correctly.
This ensures the intent is appropriately recognized and handled.
1123-1123: Ensure self.mycroft_cps is Properly Initialized
In the handle_legacy_cps method, the call to self.mycroft_cps.search(utt, message=message) relies on self.mycroft_cps being initialized. Verify that LegacyCommonPlay is correctly instantiated in the __init__ method and that the search method functions as expected.
