C++ and python clients were attempting to continue the transation transparently
after failover which is in correct. They were re-sending messages in the
transaction but there is no way to re-do transactional receives. The transaction
must be aborted.
The C++ and python clients have been modified to kill a transactional session
with a TransactionAborted exception if there is a failover.
Note the Java client already behaves correctly but not identically.
It defers raising an exception until commit rather than failing
immediately on failover, and the session can still be used.
The following commits are involved:
r1611349 QPID-5887: revised approach to implict abort
r1610959 QPID-5887: allow qpid-txtest2 to be run by make test
r1610958 QPID-5887: fix to new txtest2, acknowledge messages in the check phase to ensure queues remain drained for any subsequent runs
r1609748 QPID-5887: abort transactional session on failover; added equivalent of txtest using messaging API
This commit does the following:
- Update ha_tests.py tx_simpler_failover test to expect transaction aborted.
- Minor improvements to qpid-txtest2
- Fix native (non-swig) python client.
