------------------------------------
Summary: AzureJournalFile fails to rotate jorunals
Key: OAK-11847
URL: https://issues.apache.org/jira/browse/OAK-11847
Project: Jackrabbit Oak
Issue Type: Bug
Components: segment-azure
Affects Versions: 1.82.0
Reporter: Julian Sedding
Assignee: Julian Sedding
Rotation of the {{AzureJournalFile}} is broken since the refactoring from azure
v8 to v12, due to a change to the value passed in as the
{{{}journalNamePrefix{}}}, when constricted via {{{}AzurePersistence{}}}, see
[0].
The problem can only be observed when a "rootPrefix" is used for the Azure
segmentstore. That is why unit-tests did not detect this regression.
The culprit is that a regexp constructed using the {{{}journalNamePrefix{}}}.
However, the regexp is tested against the _filename_ derived from the journal
blob's path. Thus the regexp that is used to extract the journal's index never
matches, and the default index "0" is returned, see [1]. This means no journal
rotation takes place.
