10.0.2 (2025-01-31)

• Clean up error handling in many rcl{_action,_lifecycle} codepaths (#1202)

  * Shorten the delay in test_action_server setup. Instead of waiting 250ms between setting up 10 goals (for at least 2.5 seconds), just wait 100ms which reduces this to 1 second.

  • Small style cleanups in test_action_server.cpp

  * Reset the error in rcl_node_type_cache_register_type(). That is, if rcutils_hash_map_set() fails, it sets its own error, so overriding it with our own will cause a warning to print. Make sure to clear it before setting our own.

  * Only unregister a clock jump callback if we have installed it. This avoids a warning on cleanup in rcl_timer_init2.

  * Record the return value from rcl_node_type_cache_register_type. Otherwise, in a failure situation we set the error but we actually return RCL_RET_OK to the upper layers, which is odd.

  * Get rid of completely unnecessary return value translation. This generated code was translating an RCL error to an RCL error, which doesn't make much sense. Just remove the duplicate code.

  * Use the rcl_timer_init2 functionality to start the timer disabled. Rather than starting it enabled, and then immediately canceling it.

  * Don't overwrite the error from rcl_action_goal_handle_get_info() It already sets the error, so rcl_action_server_goal_exists() should not set it again.

  * Reset errors before setting new ones when checking action validity That way we avoid an ugly warning in the error paths.

  * Move the copying of the options earlier in rcl_subscription_init. That way when we go to cleanup in the "fail" case, the options actually exist and are valid. This avoids an ugly warning during cleanup.

  * Make sure to set the error on failure of rcl_action_get_##_service_name This makes it match the generated code for the action_client.

  * Reset the errors during RCUTILS_FAULT_INJECTION testing. That way subsequent failures won't print out ugly error strings.

  * Make sure to return errors in _rcl_parse_resource_match . That is, if rcl_lexer_lookahead2_expect() returns an error, we should pass that along to higher layers rather than just ignoring it.

  * Don't overwrite error by rcl_validate_enclave_name. It leads to ugly warnings.

  • Add acomment that rmw_validate_namespace_with_size sets the error

  * Make sure to reset error in rcl_node_type_cache_init. Otherwise we get a warning about overwriting the error from rcutils_hash_map_init.

  * Conditionally set error message in rcl_publisher_is_valid. Only when rcl_context_is_valid doesn't set the error.

  * Don't overwrite error from rcl_node_get_logger_name. It already sets the error in the failure case.

  * Make sure to reset errors when testing network flow endpoints. That's because some of the RMW implementations may not support this feature, and thus set errors.

  * Make sure to reset errors in rcl_expand_topic_name. That way we can set more useful errors for the upper layers.
