124-124: Update docstring to reflect Optional typeThe parameter type has changed from
booleantoOptional[bool], but the docstring still describes it asboolean. Please update the docstring to accurately reflect the new type and default behavior.- hostname_localhost (boolean): use localhost instead of the hostname to establish the zmq connection. In the + hostname_localhost (Optional[bool]): use localhost instead of the hostname to establish the zmq connection. In the context of an HPC cluster this essential to be able to communicate to an Executor running on a different compute node within the same allocation. And in principle any computer should be able to resolve that their own hostname points to the same address as localhost. Still MacOS >= 12 seems to disable this look up for security reasons. So on MacOS it is required to set this - option to true + option to true. Defaults to True on macOS and False otherwise.
144-147: Consider using a constant for the platform checkThe platform-specific logic is well-implemented, but consider extracting the platform string to a constant for better maintainability.

77-77: Document the default hostname behavior in test environment.Since we're removing explicit hostname configuration from these integration tests, it would be valuable to document the expected default behavior in the test environment. This helps maintain test isolation and makes the test setup more transparent.
Consider adding a comment in the test class docstring explaining:
- The default hostname behavior in the test environment
- How test isolation is maintained without explicit hostname configuration
- Any assumptions about the test environment

1-476: Add test coverage for new Optional[bool] behaviorWith the change of
hostname_localhostfrombooltoOptional[bool], we should ensure comprehensive test coverage. Consider adding test cases to verify:
- Behavior when hostname_localhost is explicitly set to None
- Behavior when hostname_localhost is explicitly set to True/False
- Behavior when hostname_localhost is not provided (default case)
Example test method to add:
def test_hostname_localhost_behavior(self): # Test default behavior (None) with InteractiveExecutor( max_workers=1, executor_kwargs={}, spawner=MpiExecSpawner, ) as exe: self.assertIsNone(exe.info["hostname_localhost"]) # Test explicit True with InteractiveExecutor( max_workers=1, executor_kwargs={"hostname_localhost": True}, spawner=MpiExecSpawner, ) as exe: self.assertTrue(exe.info["hostname_localhost"]) # Test explicit False with InteractiveExecutor( max_workers=1, executor_kwargs={"hostname_localhost": False}, spawner=MpiExecSpawner, ) as exe: self.assertFalse(exe.info["hostname_localhost"])
Based on the search results, I can now provide a final response:
Test cases need to be updated for Optional[bool] hostname_localhost behavior
The review comment is correct. The test cases need to be updated because:
- The implementation in
executorlib/shared/communication.pyshows thathostname_localhostis nowOptional[bool]with platform-specific defaults:
NonebecomesTrueon MacOS (darwin)NonebecomesFalseon other platforms- Current test cases in
test_local_executor.pyonly test withTrue, missing coverage for:
- The
Nonedefault value behavior- Platform-specific default resolution
- The
Falsevalue behaviorSuggested updates:
- Add test cases for
hostname_localhost=Noneto verify platform-specific defaults- Add test cases for
hostname_localhost=False- Consider adding platform-specific test variations

💡 Codebase verification
Found inconsistency: hostname_localhost parameter still present in test_local_executor.py
The verification revealed that while hostname_localhost parameter was removed from test_executor_backend_mpi.py, it is still being used in test_local_executor.py in multiple test cases. This indicates an incomplete refactoring where:
- The parameter is used in test metadata dictionaries
- It's included in executor_kwargs configurations
- The value is still being set to
Truein these cases
This needs to be addressed to maintain consistency with the refactoring where hostname_localhost was changed from bool to Optional[bool].
