[jira] Created: (COUCHDB-1081) Proper database header upgrade
Proper database header upgrade
------------------------------
Key: COUCHDB-1081
URL: https://issues.apache.org/jira/browse/COUCHDB-1081
Project: CouchDB
Issue Type: Bug
Components: Database Core
Reporter: Filipe Manana
Assignee: Filipe Manana
Attachments: COUCHDB-1081.patch
After upgrading an old database header, we don't set the disk_version field of the upgraded header to the latest supported version.
Also, when opening versions from more recent releases, we get a function clause crash instead of throwing an exception with an explicit message informing the version is not supported.

Filipe Manana commented on COUCHDB-1081:
----------------------------------------
Just to avoid confusion, the header upgrade procedure is not broken.
The proposed patch just avoids a function clause error when opening a database from more recent versions. Also, updating the disk_version field is not a must (after compaction we'll get an header with the latest version) but it makes it easier to analyze when (from which header/offset) a database file was upgraded (assuming no compaction happened yet).
