> Key: COUCHDB-3255
> URL: https://issues.apache.org/jira/browse/COUCHDB-3255
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Reporter: Paul Joseph Davis
>
> When a document is re-created with an attachment it receives a
> non-deterministic revision. This is due to a fairly old commit [1] that
> introduced the behavior by accidentally including information about revisions
> on disk into the revision id calculation when the revision id was being
> calculated by couch_db_updater when it realized that the update was
> re-creating a document that was previously deleted.
> I'm opening a PR with the fix.
