Is this just the same as a bad parameter error code?

I believe we have a function already for converting rmw errors to rcl errors

I think overall our error types still need to be better defined.

I think overall our error types still need to be better defined.

What are we missing?

There are far fewer RMW_RET_* types than RCL_RET_* types. Getting a rcl_ret_t from a rmw_ret_t feels like rcl_ret_t isn't living up to its potential.

Where is this used? Is there a reason we need to expose the rmw layer above the rcl layer?

Looks like it is not used anywhere. But neither is rcl_subscription_get_rmw_handle(). However, rcl_publisher_get_rmw_handle() is used in rclcpp...

Let's just leave it here for now.

Apparently, this function is needed by the SET_ADD_RMW macro in wait.c.

+  bool taken;
+  RCL_CHECK_ARGUMENT_FOR_NULL(event, RCL_RET_INVALID_ARGUMENT);
+  RCL_CHECK_ARGUMENT_FOR_NULL(event_status, RCL_RET_INVALID_ARGUMENT);
+  rmw_ret_t ret = rmw_take_event(event->impl->rmw_handle, event_status, &taken);


Seems a little odd that we're diverging rcl_take_event and rmw_take_event in terms of having the extra parameter to determine if something was actually taken. Why can't they both work the same.

I am for removing the taken parameter.

Will remove the taken parameter.

On second thought, it looks like the other rmw_take() functions also have this extra taken boolean. We should probably leave it in there to be consistent.

Call rcutils_logging_shutdown() in TearDown to avoid leaking logging internal objects. As any change to this file makes test_logging_named fail, this releaxes the EXACT_EQ call on g_last_log_event.location->line_number[1]. Instead of looking for a particular value, we test an invariant of the field (line numbers are positive). Finally, in test_logging_function, initialize g_counter and g_function_called values to make sure the test will not fail even if `--gtest_repeat=2` is passed. Other tests are still failing when this flag is passed: [ FAILED ] TestLoggingMacros.test_logging_once [ FAILED ] TestLoggingMacros.test_logging_skipfirst [ FAILED ] TestLoggingMacros.test_logging_skipfirst_throttle However, fixing those tests would require actually changing the logging implementation which is out of the scope of this change.
