Where the mysql database uses optimistic concurrency, will Openstack deal with catching the exception and retrying the transaction ?
Found the answer, deadlock situations are supported in nova code. Will check Openstack components and post here, if anyone can save me time looking through code, that would be a big help.
Hi Keith,
The main code to process sql connection failed sits here: https://github.com/openstack/nova/blob/master/nova/openstack/common/db/sqlalchemy/session.py#L674 (https://github.com/openstack/nova/blo...)
these code will be moved into 'oslo.db' which is a part of project 'oslo' in the future.
Hoping that help you. cheers, gtt
