Session is still usable after Close. #568

Closed oleriajm closed 7 months ago

oleriajm commented 7 months ago

The Session must not be usable after the caller closed it explicitly.

Following pattern just works at the moment

    session := driver.NewSession(ctx, sessionConfig)
        session.Close()

        session.ExecuteRead(...)
        // and keep using session with more operations...

This is because Closing session cleans up pool/router etc, but all the references are still preserved.

As a good practice, the behavior should be fail-fast/fail-hard once you called Close on it

Fixed by PR https://github.com/neo4j/neo4j-go-driver/pull/570, attempting to use a closed session now returns a usage error. Thank you @oleriajm for bringing this to our attention 👍.
