First implementation #4

ivanpauno · 2019-10-10T19:29:09Z

Adds:

Generation of common messages.
- A package called rmw_dds_common_generators. It basically depends on rosidl_generator_c, rosidl_generator_cpp, rosidl_typesupport_introspection_c, rosidl_typesupport_introspection_cpp, and a group depend in rosidl_typesupport_cpp_packages.
  This is used to avoid depending in the default generators, which also depend in rmw_typesupport_c/cpp creating a circular dependency.
  This metapackage is needed, as there is no build_tool_group_depend equivalent.
- rmw_dds_common generates three messages Gid.idl, NodeCustomInfo.idl, ParticipantCustomInfo.idl.
- Each dds implementation will generate a *__type_support.cpp for the messages manually (example here).
GraphCache class, that could be used in all the vendors.
A common Context class, that will be an implementation detail in all the rmw_context_t of rmw implementations based on DDS, that uses one Participant per Context.

@wjwwood I realized recently that I'm not triggering the graph guard condition in many cases I should.
That isn't causing failures, just because lack of tests.
I will pass a rmw_guard_condition_t * to GraphCache, and trigger it in all the setters.

wjwwood · 2020-02-10T21:37:47Z

Ok, yeah we do need to be triggering the node guard condition anytime the graph changes. That should have been the case before.

It would be nice to have new tests in rcl or something to ensure that this is happening. Unfortunately these tests are notoriously complicated, due to their nature of being asynchronous.

Done in
ros2/rmw_fastrtps@bffc25c and 8d6e757.

Opened issue.

@ivanpauno can you update the original description before you merge this? It looks out of date, and it's most likely what someone will look at when coming back to this in the future.

Also, please go ahead and move this to the ROS 2 organization.

+      case EndpointCreator::BARE_DDS_PARTICIPANT:
+        node_name = "_CREATED_BY_BARE_DDS_APP_";
+        node_namespace = "_CREATED_BY_BARE_DDS_APP_";


@ivanpauno why not using these string literals when first constructing the tuple? Then you can optimize this switch away.

I could optimize EndpointCreator::BARE_DDS_PARTICIPANT case, but not also EndpointCreator::UNDISCOVERED_ROS_NODE. I find clearer if all the cases are together.

+using DemangleFunctionT = GraphCache::DemangleFunctionT;

+void
+check_results(


@ivanpauno nit: for all check_* functions, consider not using default parameters for empty sets or zero counts and provide them explicitly instead. IMO it'll make the tests much easier to read.

I'd also be a bit more verbose on the naming e.g. check_results -> check_graph_cache_state. Same for the rest.

Still applies, but won't block on it.
