commit fd93e19f2a415b3803700fc491749daba01a4390 Author: Assaf Muller <[email protected]> Date: Fri Mar 18 16:29:26 2016 -0400 Change get_root_helper_child_pid to stop when it finds cmd get_root_helper_child_pid recursively finds the child of pid, until it can no longer find a child. However, the intention is not to find the deepest child, but to strip away root helpers. For example 'sudo neutron-rootwrap x' is supposed to find the pid of x. However, in cases 'x' spawned quick lived children of its own (For example: ip / brctl / ovs invocations), get_root_helper_child_pid returned those pids if called in the wrong time.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1558819 Title: Fullstack linux bridge agent sometimes refuses to die during test clean up, failing the test Status in neutron: Fix Released Bug description: Paste of failure: http://paste.openstack.org/show/491014/ When looking at the LB agent logs, you start seeing RPC errors as neutron-server is unable to access the DB. What's happening is that fullstack times out trying to kill the LB agent and moves on to other clean ups. It deletes the DB for the test, but the agents and neutron- server live on, resulting in errors trying to access the DB. The DB errors are essentially unrelated - The root cause is that the agent refuses to die for an unknown reason. The code that tries to stop the agent is AsyncProcess.stop(block=True, signal=9). Another detail that might be relevant is that the agent lives in a namespace. To reproduce locally, go to the VM running the fullstack tests and load all CPUs to 100%, then run: tox -e dsvm-fullstack TestLinuxBridgeConnectivitySameNetwork To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1558819/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
