nickva opened a new pull request #2133: Fix DB reopen behavior
URL: https://github.com/apache/couchdb/pull/2133
 
 
   Previously if a VDU was updated in the `before_doc_update/3` handlers, the Db
   handle wasn't refreshed soon enough such that the `prepare_and_validate/3`
   would not see the newly update VDU and would not run it.
   
   To fix make a stale Db throws an exception which bubbles up all the way to
   `fabric2_fdb:transactional/2` where the transaction is retried again with a
   reopened Db.
   
   During `reopen/1` make sure to properly transfer the `user_ctx` property to the
   new handle, and also make sure `user_ctx` is removed from `db_options` to avoid
   caching it in `fabric2_server`.
