Subject: Update ensure()/reconnect() to catch MessagingError
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=9a830b370551019a4bd3a0c7504f48961e755bd4;p=openstack-build%2Fneutron-build.git

Update ensure()/reconnect() to catch MessagingError

The error handling code that gets connections reset if necessary
caught ConnectionError. It really needs to catch MessagingError,
which ConnectionError inherits from. There are other types of
MessagingErrors that may occur, such as InternalError, and they need
to cause the connection to reset, as well.

This fix has already been merged into oslo.messaging.
