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

• Type: Bug
• Status: Open

Description

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.
