112-115: Excellent use of context manager for socket handlingThe implementation of the context manager (
withstatement) for socket handling is a significant improvement. It ensures that the socket is properly closed after use, addressing the ResourceWarning issue mentioned in the PR objectives. This change follows Python best practices for resource management and maintains the existing functionality.Consider adding explicit error handling within the context manager to manage potential network-related exceptions. Here's a suggested improvement:
def send_request(port, message): try: with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.connect(("localhost", port)) pickle.dump(message, s.makefile("wb")) return pickle.load(s.makefile("rb")) except (socket.error, pickle.PickleError) as e: # Log the error or handle it as appropriate for your application raise ConnectionError(f"Failed to communicate with IPC server: {e}")This addition will provide more informative error messages and allow for graceful error handling in the calling code.

126-150: LGTM: Well-structured test for socket closure on exception.This test function effectively verifies that the socket is properly closed when an exception occurs during
send_request. It aligns well with the PR objective and uses mocking appropriately to simulate the behavior without actual network operations.A minor suggestion for improvement:
Consider adding an assertion to verify that
mock_socket_instance.close()is called. This would provide an extra layer of certainty that the socket is explicitly closed. You can add this assertion just before the existing assertions:mock_socket_instance.close.assert_called_once()This addition would make the test even more robust in ensuring proper resource management.

16-18: LGTM: New imports are appropriate for the added test.The new imports (unittest, BytesIO, and MagicMock) are correctly added and are necessary for the new test function. These are standard Python libraries, which is good for maintaining minimal external dependencies.
Line range hint
1-150: Summary: Excellent addition to improve test coverage for socket closure.The changes in this file effectively address the PR objective of ensuring proper socket closure. The new test function
test_socket_closes_on_exceptionis well-implemented and uses appropriate mocking techniques to verify the behavior without actual network operations.Key points:
- The new test aligns perfectly with the goal of eliminating ResourceWarnings due to unclosed sockets.
- The implementation follows good testing practices, including the use of mocking and specific assertions.
- Existing tests remain unchanged, maintaining the integrity of previous test coverage.
These changes contribute to the overall robustness of the IPC functionality in FiftyOne by ensuring that edge cases related to exception handling and resource management are properly tested.
