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