Firefox Automation report – week 25/26 2014

In this post you can find an overview about the work happened in the Firefox Automation team during week 25 and 26.


June the 11th was actually the last Automation Training day for our team in Q3. About the results you can read here. We will implement some changes for the next quarter, when we most likely want to host 2 of them.

Henrik finally got the time to upgrade our Mozmill-CI systems to the lastest LTS version of Jenkins. There were a bit of changes necessary but in general all went fine this time, and we can see some great improvements. Especially the long delays when sending out job results seem to be gone.

Further Henrik investigated the slow behavior with the mozmill-ci production master, when it is under load, e.g. QA runs ondemand update tests for releases of Firefox. The main problem stays with Java, which is taking up about 100% of the CPU. Because of this the integrated web server cannot serve pages in a timely manner. Adding a 2nd CPU to this node gave us way better response times.

Given that the new version of Ubuntu came out already in April, we want to have our Mozmill tests also run on that platform version. So we got new VM spun-up by IT, which we now have to puppetize and bring online. But this may still take a bit, given the remaining blockers for using PuppetAgain.

While talking about Puppet we got the next big change reviewed and landed. With bug 1021230 we now have our own user account, which can be customized to our needs. And that’s what we totally need, given that our infrastructure is so different from the Releng one.

Also for TPS we made progress, so the new TPS-CI production machine came online. Yet it cannot replace the current CI due to still a fair amount of open blockers, but hopefully by end of July we should be able to turn the switch.
