Title:
inconsistent locations of retry decorators
Status in networking-midonet:
Fix Released
Status in neutron:
Fix Released
Bug description:
We're trying to have DB error retry operations handled at the API
layer (e.g. [1][2]). However, several have snuck into the ML2
plugin[3] so it's not clear which decorator is responsible for
specific errors that occur and it's not clear if a transaction is
still ongoing leading to repeatable read problems.
We should keep these at one level of the pipeline to make
troubleshooting easier and to avoid confusion about what state
everything will be in when things are retried.
