Hello, We have a TG 2.1.5 application running against Postgresql and Amazon RDS. We are often getting a OperationError or a ConcurrentModificationError during some long transactions. The usual way to deal with them is laid out in [1], which suggests that the user should simply resubmit transaction due to the transient error. After looking around repoze.tm2 I note that it doesn't look like it will retry.
1. Any suggestions for implementing retries at transaction.manager level.. should we be using the zope.sqlalchemy manager which does seem to implement some of the retry logic? It also seems that we could simply ask the client side to reload (return a http 409) and resubmit the entire request. Anybody have any experience with this ?
