Alexey Goncharuk commented on IGNITE-12412: ------------------------------------------- Done, the visa is acquired on a separate refactoring + fix PR. > Incomplete check for ABA problem in PageMemoryImpl#PagePool > ----------------------------------------------------------- > > Key: IGNITE-12412 > URL: https://issues.apache.org/jira/browse/IGNITE-12412 > Project: Ignite > Issue Type: Improvement > Reporter: Alexey Goncharuk > Assignee: Alexey Goncharuk > Priority: Critical > Time Spent: 1h 10m > Remaining Estimate: 0h > > In current implementation, {{PagePool#releasePage}} clears the counter part > of the returned page ID, which effectively disables the ABA check intended in > the class. This issue can be rarely reproduced on zOS during checkpoints > (when pages are being taken and returned to the checkpoint pages pool). > I managed to write a unit-test to reproduce this issue on x86. -- This message was sent by Atlassian Jira (v8.3.4#803005)
