----------------------------------------
Summary: Thermos runner collect_updates() gets stuck in a while
loop when timeout is 0
Key: AURORA-669
URL: https://issues.apache.org/jira/browse/AURORA-669
Project: Aurora
Issue Type: Bug
Components: Thermos
Reporter: Maxim Khutornenko
The following code in runner.py:collect_update() may result in an infinite
while loop when the provided timeout is passed as 0:
{noformat}
while True:
...
if timeout and total_time >= timeout:
break
...
{noformat}
We have observed a case when the thermos runner gets stuck in a "deadlocked"
state not reacting to SIGTERM with the last message in __main__.log as:
{noformat}
D0827 15:35:26.022495 30886 runner.py:856] Run loop: Work to be done within 0.0s
{noformat}
