    Description

      see https://github.com/mariadb-corporation/mariadb-connector-nodejs/issues/195

      The 3.0.0 release seems to have introduced a bug that wasn't there in 2.5.6.

      Scenario

      Using the promise API

      • Create a connection pool
      • Get a connection
      • Perform some requests
      • Release connection
      • Shutdown the DB server
      • Error ER_CONNECTION_KILLED is sometimes caught in the error event of the connection, sometimes not
      • Error ER_SOCKET_UNEXPECTED_CLOSE is sometimes caught in the error event of the connection, sometimes not
      • One more ER_SOCKET_UNEXPECTED_CLOSE is raised but I'm unable to catch it, thus my node process crashes. It doesn't get caught by the error event handler that I added to the connection.

          In 3.0, when releasing connection to pool not with connection.release() but connection.close(), connection wasn't given back to pool, but killed.
          When killing connection, server send a ER_CONNECTION_KILLED error that can sometime be caught by connector before socket is closed, but that's not assured, then having just an ER_SOCKET_UNEXPECTED_CLOSE error.
