Title:
wait_until_true is not rootwrap daemon friendly
Status in neutron:
Invalid
Bug description:
As wait_until_true uses an eventlet timeout, it can happen that
timeout exception is raised while waiting for output from rootwrap
daemon. This leaves data in rwd socket and next attempt to run command
via rootwrap daemon returns the previous data. There is a bug reported
on oslo.rootwrap - https://bugs.launchpad.net/neutron/+bug/1654287
With a switch of fullstack tests to use rootwrap, it happens a lot
that timeouts are raised while running commands in rwd (eg.
http://logs.openstack.org/67/488567/2/check/gate-neutron-dsvm-
fullstack-ubuntu-xenial/eb8f9a3/testr_results.html.gz)
This bug is to track down an eventlet free solution - we can
generalize approach here
https://review.openstack.org/#/c/421325/3/neutron/cmd/netns_cleanup.py
and since we'll get rid of eventlet dependency, we can move
wait_until_true to neutron-lib.
