[jira] [Created] (ARROW-2629) [Plasma] Iterator invalidation for pending_notifications_

Philipp Moritz created ARROW-2629:

             Summary: [Plasma] Iterator invalidation for pending_notifications_
                 Key: ARROW-2629
                 URL: https://issues.apache.org/jira/browse/ARROW-2629
             Project: Apache Arrow
          Issue Type: Bug
          Components: Plasma (C++)
            Reporter: Philipp Moritz
             Fix For: 0.10.0

This was discovered when running the Ray integration tests. In send_notifications we are modifying pending_notifications_, which invalidates the iterator in the for each loop in push_notification.

It's not easy to reproduce, so I don't have a regression test unfortunately, but I'll post a patch that fixes it.
