Obfuscated UI exception message debugging
by Alexander Wels 08 Jan '16

08 Jan '16

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 08 Jan '16

08 Jan '16

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 05 Jan '16

05 Jan '16

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 05 Jan '16

05 Jan '16

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. -- Barak Korren bkorren(a)redhat.com RHEV-CI Team
