[jira] [Updated] (QPID-5888) transaction should always be aborted
on failover
[ https://issues.apache.org/jira/browse/QPID-5888?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gordon Sim updated QPID-5888:
-----------------------------
Component/s: (was: C++ Client)
Python Client
Description:
At present, failover is entirely hidden from the client which is the wrong thing to do for a transactional session.
The client should always abort the transaction on a failed session, and not try to failover transparently. This is what would happen if the commit failed due to some internal error on the broker (e.g. no space on disk or whatever).
was:
At present, if a commit is the first operation after a failover, it will be aborted. However if any other operation (e.g. a send or accept) is done after the failover, but before the commit, then the subsequent commit will succeed.
This hides the failover from the client which is the wrong thing to do for a transactional session.
The client should always abort the transaction on a failed session, and not try to failover transparently. This is what would happen if the commit failed due to some internal error on the broker (e.g. no space on disk or whatever).
