commit 7bb1bbba365ad1358d6e66f88a8a48b7261c024e Author: Slawek Kaplonski <skapl...@redhat.com> Date: Mon Jul 15 13:03:30 2019 +0200 Fix race in test_keepalived_state_change_notification In case if initial keepalived status find in keepalived_state_change.MonitorDaemon is "master" this test_keepalived_state_change_notification was failing because there was 4 calls to the mocked enqueue_state_change() method instead of 3. This patch changes test to wait until 3 or 4 calls to this method will be counted and it also changes assertions of what state should be set on which call. Before the patch test was expecting that calls are always like: backup, master, backup but if there are 4 calls it is like: backup, master, master, backup. As it doesn't matter if there was one or two calls with "master" state, test will now assert that the last call is always with "backup" state.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1836565 Title: Functional test test_keepalived_state_change_notification may fail do to race condition Status in neutron: Fix Released Bug description: Functional test neutron.tests.functional.agent.l3.test_ha_router.L3HATestCase.test_keepalived_state_change_notification may fail due to setting initial status of keepalived_state during starting of IP monitor. Some time ago patch https://review.opendev.org/#/c/642295/ introduced checking initial status of VIP in router's namespace during IPMonitor initialisation process. It works fine but in this specific test, if keepalived will first set router to master and than IPMonitor will be spawned, enqueue_state_change() function will be called 4 instead of 3 times and test will fail.
