Julian Sedding created OAK-11847:
------------------------------------

             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.
