ros::init with no __name and name = "" is not tested in roscpp? #891
Description
I'd like to report a possible bug at roscpp initialization.
In roscpp initializer ros::init (const M_string &remappings, const std::string &name, uint32_t options=0), a node can be initialized even empty string is passed to name argument if remappings are passed through from command line arguments.
But if __name:=foobar is removed from remappings and name is empty, ros node can be registered with invalid name, which can occur unexpected errors.
I did experiment in some conditions. the result is followings:
| remap_name | node_name_empty | test_group | this_node::name | this_node::namespace |
|---|---|---|---|---|
| true | false | false | /test_node | / |
| true | false | true | /group1/test_node | //group1 |
| true | true | false | /test_node | / |
| true | true | true | /group1/test_node | //group1 |
| false | false | false | /test_node | / |
| false | false | true | /group1/test_node | //group1 |
| false | true | false | / | / |
| false | true | true | //group1 | //group1 |
In the last condition, namespace and name are the same and other nodes cannot resolve the node.
