TSAN error for send_node_id_handshake test #2060

commented Jun 5, 2019

When running Clang/TSAN I get the following:

What appears to happen is that the last std::shared_ptr<nano::node> reference gets released by an alarm operation which then calls the ~stat destructor. This modifies the map (unprotected) and at the same time a packet is processed and a stat is trying to be incremented. I don't think this is the fault of stats rather the slightly random nature where the last node shared_ptr reference is released which can cause problems in quite a few areas. But as this is the one that TSAN is warning about I have fixed it. Just adding a stop variable/function to prevent modifying stats when closing down the node. Have moved stats higher up the member list as most things have a dependency on it.
