-----------------------------------------
Summary: Use valid tag for page write unlock while reading cold
page from disk.
Key: IGNITE-9445
URL: https://issues.apache.org/jira/browse/IGNITE-9445
Project: Ignite
Issue Type: Bug
Reporter: Alexei Scherbakov
Assignee: Alexei Scherbakov
The problem arises when passing pageId with not actual page rotation tag to
org.apache.ignite.internal.processors.cache.persistence.pagemem.PageMemoryImpl#acquirePage(int,
long, boolean).
It's not possible in advance to know the actual value without reading stored
page.
Such scenario may lead to locked forever page if passed and persisted tags are
different.
Solution - unlock page using actual(persisted) tag value.
