Obfuscated UI exception message debugging
by Alexander Wels
Hi,
With the release of oVirt 3.6 the UI team added a handler for any uncaught
exceptions. This handlers shows a popup that basically says the following:
Uncaught exception occurred. Please try reloading the page. Details: [some
information]
With the some information giving some indication of what happened. Usually
that information is less than helpful. You can see the associated stack trace
in the browser console, but since all the code is obfuscated the stack trace
is usually pretty useless as well. I have been seeing a lot of bugs being
opened about the popup. In an effort to help everyone understand what is going
on and help us debug the root cause of the problem I created a wiki page [1]
that shows some steps to 'de-obfuscate' manually the stack trace and provide
hopefully some useful information.
Doing all of this labor intensive and not very intuitive, so in an effort to
automate the process, I have also created a patch that sends the obfuscated
stack trace to the engine and some code to automatically de-obfuscate the
stack trace and write it to a UI specific log [2]. Once that patch is merged
looking up UI exceptions should be as simple as looking in that log.
Hopefully the above will aid everyone in debugging any strange exceptions
generated by the UI.

[VDSM] [REVIEW] Introduce commands package to separate execCmd and AsyncProc from utils
by Nir Soffer
Hi all,
This patch moves execCmd and friends to new commands module, so code not using
these can be ported to Python 3. More work is needed to make execCmd compatible
with Python 3, and we don't want to delay the work on other modules
that do not depend
on it, but import utils.
Since this change touches all sub systems in vdsm, subsystems maintainers
should review and *verify* that it does not break anything.
Please review and verify:
https://gerrit.ovirt.org/51421
We are going to merge it on end of next week, so better check that it does not
break your code before that.
Thanks,
Nir

4.0 GenericApiGWTService responses no longer being gzipped.
by Alexander Wels
Hi,
While I was the network traffic in my browser for an issue I was working on. I
noticed the response sizes being unusually large. When I compared it against a
similar sized 3.6 installation the response was huge. Checking the headers it
appears that the response no longer is gzipped before being send to the user.
Does anyone know of any changes to that recently? I am unsure of what exactly
gzipped the responses to begin with. I was assuming either a filter or some
jboss setting.
If anyone could shed some light on this it would be appreciated.
Thanks,
Alexander

Jenkins server restarted
by Barak Korren
The oVirt Jenkins server seems to have gone into a particularly long
garbage collection process, so I just restarted it 10 minutes ago to
make it responsive again.
If you had jobs running at that time they will never finish, or finish
with failure, please restart them.
