[jira] [Created] (OAK-9212) AzureArchiveManage.listArchives() should not delete segments

Aravindo Wingeier created OAK-9212:
--------------------------------------

             Summary: AzureArchiveManage.listArchives() should not delete segments
                 Key: OAK-9212
                 URL: https://issues.apache.org/jira/browse/OAK-9212
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: segment-azure
    Affects Versions: 1.32.0
            Reporter: Aravindo Wingeier
             Fix For: 1.36.0


When the segments are listed on an azure blob store and the "0000.*" blob is missing, it will delete all other segments. This behaviour was introduced with OAK-8566. 

*Change:* This destructive operation should not happen in method the _AzureArchiveManage.listArchives()_ which indicates a read-only operation. One option is to pull out this functionality and call it somewhere else. 

*Why is this an issue?*  There is a recovery option in org.apache.jackrabbit.oak.segment.file.tar.TarReader#collectFileEntries which calls org.apache.jackrabbit.oak.segment.file.tar.TarReader#backupSafely. If the recovery is run concurrently with _AzureArchiveManage.listArchives()_ the result can be unexpected.
