Summary of Changes
Hello @MervinPraison, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request addresses a bug that caused duplicate display outputs by ensuring that the synchronous display_interaction function consistently triggers registered callbacks. Previously, only the asynchronous version of this function executed callbacks, leading to inconsistent behavior when the LLM class used the synchronous path. The changes guarantee that display interactions are processed exactly once per LLM response, preventing redundant output while maintaining backward compatibility.
Highlights
- Fix for Duplicate Callbacks: The synchronous
display_interactionfunction now correctly executes registered callbacks by callingexecute_sync_callback. This resolves an issue where only the asynchronous version ofdisplay_interactionwas triggering callbacks, leading to duplicate displays when the LLM class utilized the synchronous path. - Improved Callback Testing: Existing tests in
test_duplicate_callback_fix.pyhave been updated to directly utilize theregister_display_callbackmechanism for mockingdisplay_interaction's behavior. This provides a more accurate and robust way to verify callback functionality and includesfinallyblocks to ensure proper cleanup of registered callbacks after each test. - New Standalone Callback Test: A new simple test script,
test_simple.py, has been added. This script provides a direct, isolated verification of thedisplay_interactionandregister_display_callbackfunctionality, confirming the fix outside of the main test suite.

Bug: Callback Parameter Name Mismatch
A TypeError occurs when execute_sync_callback is called because it passes the argument as message=..., but registered callbacks (e.g., test_callback in test_simple.py) expect the first parameter to be named prompt. This parameter name mismatch prevents the argument from being correctly matched.

Code Review
This pull request fixes a bug where synchronous callbacks for display_interaction were not being executed. The core logic change in main.py is sound. However, the change in main.py seems to cause duplicate callback invocations because llm.py calls both execute_sync_callback and display_interaction in some code paths. I've also corrected a function signature in the new test_simple.py script.
| # Execute synchronous callbacks | ||
| execute_sync_callback( | ||
| 'interaction', | ||
| message=message, | ||
| response=response, | ||
| markdown=markdown, | ||
| generation_time=generation_time | ||
| ) |

This change correctly adds the synchronous callback execution to display_interaction. However, the LLM.get_response method in src/praisonai-agents/praisonaiagents/llm/llm.py has code paths where it calls both execute_sync_callback('interaction', ...) and display_interaction(...) for the same response. With this change, the callback will be triggered twice in those cases. For example, in the reasoning_steps path (llm.py:728), execute_sync_callback is called directly (llm.py:749) and then display_interaction is called (llm.py:759), which will now trigger the callback a second time. To fix this, llm.py must be refactored to remove the direct calls to execute_sync_callback('interaction', ...) and rely solely on display_interaction for both display and callbacks.

The signature of test_callback has an issue that could lead to incorrect behavior: the first parameter is named prompt, but the display_interaction function calls the callback with a keyword argument message. This will cause a TypeError at runtime. The parameter should be renamed to message.

129-136: LGTM! Callback execution added to sync version correctly.This change successfully addresses the duplicate callback issue by ensuring the synchronous
display_interactionfunction also executes registered callbacks, mirroring the behavior of the async version. The parameters passed toexecute_sync_callbackare consistent with the async version'sexecute_callbackcall.test_simple.py (1)
25-40: Excellent test structure for callback verification.This test effectively validates the callback mechanism by:
- Registering a callback for the 'interaction' event
- Calling
display_interactiononce- Verifying exactly one callback invocation
The test serves as both verification and documentation of the callback fix.
test_duplicate_callback_fix.py (3)
18-27: LGTM! Parameter naming corrected for consistency.The mock callback function correctly uses
messageas the first parameter, matching the actualdisplay_interactionfunction signature. This ensures proper parameter passing when the callback is invoked.
33-61: Excellent refactor to use callback registration.The transition from patching
display_interactionto registering a mock callback is much cleaner and better reflects the actual fix. The try/finally block ensures proper cleanup of the callback registration.
165-203: Comprehensive test coverage for async scenario.The async test properly validates that the callback mechanism works correctly in asynchronous contexts, ensuring the fix doesn't break async functionality while addressing the sync callback issue.

🛠️ Refactor suggestion
Fix parameter naming inconsistency in callback.
The callback function uses prompt as the first parameter, but the actual display_interaction function passes message. This inconsistency could cause confusion or errors.

In test_simple.py around lines 15 to 24, the callback function parameter is
named 'prompt' but the corresponding caller uses 'message'. Rename the first
parameter of the test_callback function from 'prompt' to 'message' to align with
the caller and avoid confusion or errors.

Fixes the duplicate callback issue by adding callback execution to the synchronous display_interaction function.
The issue was that only the async version of display_interaction was executing callbacks, but the LLM class uses the sync version everywhere.
This fix ensures that display_interaction is called exactly once per LLM response, preventing duplicate displays while maintaining backward compatibility.
