Vdsm: ovirt-4.4.3 branch created
by Milan Zamazal
Hi,
ovirt-4.4.3 branch has been created in Vdsm. Any patches after Vdsm
4.40.35 that should go to 4.4.3 (blockers only) must be backported.
You can merge 4.4.4+ patches to master now.
Regards,
Milan

ovirt-engine 4.4.3 was branched
by Tal Nisan
Hi everyone,
As you probably know, yesterday we've tagged and built the 4.4.3 RC build,
to maintain stability and to allow work on 4.4.4 we have branched 4.4.3 so:
For your 4.4.4 work - just push to master
For 4.4.3 work (blockers/exceptions only!) - push to master and once it's
merged backport to the ovirt-engine-4.4.3.z branch
Thanks!

callback hanging making commands executing serial
by Liran Rotenberg
Hi all,
Investigating a bug about serial execution
<https://bugzilla.redhat.com/1885286> of the same command more than once
shows a problem with our callbacks.
The problem is felt when we have synchronized operation (such as running
ansible runner service) that takes a bit time to be executed.
The problem is, when running multiple commands and one has synchronized
long operation within a child command, it will hang out all the commands
running on the engine using callbacks.
The good example is given in the bug, since export OVA command using
ansible(sync) and the pack_ova script takes time to finish.
This is not really noticeable with short synchronized commands, but it does
execute serial for them as well instead of parallel.
Running export to OVA command and then other commands with callbacks will
get them hanging if the export command callback started and it reached to
performNextOperation.
Some technical details:
We have one thread in CommandCallbacksPoller[1] that runs, collects the
current command on the engine and processes them.
Once we have the above scenario (let's say 2 commands), the first one will
go into callback.doPolling in invokeCallbackMethodsImpl. [2]
In that case it will go to ChildCommandsCallbackBase::doPolling,
eventually to childCommandsExecutingEnded. [3]
While there are more actions to perform we will do performNextOperation
[4], which calls executeNextOperation (in the bug case [5]).
When the next operation is long and synchronized, this will block the
CommandCallbacksPoller thread and only when it finishes the thread is
released and the callbacks continue working.
Any idea how to solve this issue?
Regards,
Liran

This fails compilation. Liran already commented there with details,
posting this for visibility.
Is anyone handling this? Should we revert?

VDSM CI Fails

Hi all,
I am seeing the following error in VDSM CI -

I guess this is related to latest networking changes, maybe some patches
were wrong, breaking my database?
Do we have a way to fix this? I don't want to clear my database, it has
useful storage and host setup.
Thanks,
