-----------------------------------
Summary: Race in preloading/unswapping
Key: IGNITE-614
URL: https://issues.apache.org/jira/browse/IGNITE-614
Project: Ignite
Issue Type: Bug
Components: cache
Reporter: Semen Boikov
Assignee: Yakov Zhdanov
Priority: Critical
Fix For: sprint-3
During unswap entry is removed from swap then unswap listener is notified, and
this logic in preload supply worker:
- register unswap listener
- iterater over heap
- iterate over swap
- remove unswap listener
- iterate over entries recorded by unswap listener
There is a race: entry is rmoved from unswap, listener is not notified yet, at
this moment supply worker remvoes unswap listener.
These tests fail from time to time because entry can be missed:
