Eli Mesika has submitted this change and it was merged. Change subject: engine: Adding unique(vds_id, name) constraint to vds_interface ...................................................................... engine: Adding unique(vds_id, name) constraint to vds_interface and removing duplicate entiries in case there were any. Due to a bug that was already fixed, more than one GetCaps could be executed simultaneously. In some scenarios of the race the same nic could be created more than once. This patch cleans the duplicate entities from vds_interface table (leaves just the last updated entry). The building proccess of the network_attachments assumes there are no such duplicates in vds_interface, so the duplicates should be cleaned up from vds_interface prior building the network_attachments table. In case the user already run the add_network_attachment upgrade script- 1. If succeeded- it means his vdS_interface table doesn't have duplicates, so the is no need for clean up. 2. If failed- it means the add_network_attachment upgrade script is not marked as a script the already have run. So now, when running the setup, the duplicates clean will occur before building the network_attachments and everything should work fine.
