> Page replacement can reload invalid page during checkpoint
> ----------------------------------------------------------
>
> Key: IGNITE-12081
> URL: https://issues.apache.org/jira/browse/IGNITE-12081
> Project: Ignite
> Issue Type: Bug
> Reporter: Dmitriy Govorukhin
> Assignee: Dmitriy Govorukhin
> Priority: Critical
> Fix For: 2.7.6
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> There is a race between {{writeCheckpointPages}} and page replacement process:
> * Checkpointer thread begins a checkpoint
> * Checkpointer thread calls {{getPageForCheckpoint()}}, which will copy page
> content *and clear dirty flag*
> * Page replacement tries to find a page for replacement and chooses this
> page, the page is thrown away
> * Before the page is written back to the store, the page is acquired again.
> As a result, an older copy of the page is brought back to memory, which
> causes all kinds of corruption exceptions and assertions.
> The attached unit test demonstrates the issue. It is likely that all
> baselines are affected starting from 2.4
> As a part of this ticket, we must add more unit-tests for checkpointing
> protocol invariants we rely on.
