60-61: LGTM! Consider adding a test case for the new variant.The addition of the
AbortProcessExceptionvariant enhances error handling by providing more context.However, consider adding a test case to ensure the new variant works as expected.

110-110: LGTM! Verify the function usage in the codebase.The change in return type to
Result<Option<RemotingCommand>>introduces a more robust error handling mechanism.However, ensure that all function calls to
process_requestare updated to handle the new return type.Verification successful
The function usage has been updated correctly.
The calls to
process_requesthandle the new return typeResult<Option<RemotingCommand>>appropriately.

65-65: LGTM! Consider adding tests for the new RPC hooks.The addition of the
rpc_hooksfield enhances the control flow by allowing for customizable behavior through the use of RPC hooks.However, consider adding tests to ensure the new RPC hooks work as expected.
81-91: LGTM! Consider adding tests for the newdo_before_rpc_hooksmethod.The
do_before_rpc_hooksmethod enhances the control flow by allowing for pre-processing of requests.However, consider adding tests to ensure the method works as expected.
93-103: LGTM! Consider adding tests for the newdo_after_rpc_hooksmethod.The
do_after_rpc_hooksmethod enhances the control flow by allowing for post-processing of responses.However, consider adding tests to ensure the method works as expected.
240-241: LGTM! Consider adding tests for therpc_hooksfield inConnectionListener.The addition of the
rpc_hooksfield inConnectionListenerenhances the control flow by allowing for customizable behavior through the use of RPC hooks.However, consider adding tests to ensure the field works as expected.
361-361: LGTM! Verify the function usage in the codebase.The addition of the
rpc_hooksparameter in therunfunction enhances the control flow by allowing for customizable behavior through the use of RPC hooks.However, ensure that all function calls to
runare updated to handle the new parameter.Verification successful
Ensure all calls to
runhandle the newrpc_hooksparameter.The
runfunction inrocketmq-remoting/src/runtime/server.rshas been updated to include therpc_hooksparameter. From the previous context, we see that the call to thisrunfunction includes an empty vector forrpc_hooks(i.e.,vec![]). This confirms that the call is updated to handle the new parameter.
