Alexander Tivelkov 5c7e20a742 Retry-on-deadlock added to modify package db api ... On some HA database deployments such as MySQL Galera the transaction locks are optimistic, and if the same data gets modifyed concurrently DB server may throw a DBDeadlock error which is intended to be handled by the caller app. This patch adds appropriate retrying logic into the catalog db api methods, so the operation to upload, modify or delete the package gets retryed if the deadlock occurs due to this optimistic locking behavior. It uses oslo_db_api.wrap_db_retry helper decorator from oslo library. Closes-Bug: #1502589 Change-Id: I8d7b3dfb02a31eba6d55ba0bf89ac0cf05f1313d		2015-10-08 15:49:51 +03:00
