[Bug 1017113] Re: FTBFS: Sveral tests fails
Hi Martin. These are basically timeouts because each test needs to finish in less than 5 seconds. Some of them take 1 - 2 seconds normally, so if your system gets busy for a second, that can be enough to push a few of them over 5 seconds. A few tips: 1) I use sbuild, not pbuilder. If you use the 'mk-sbuild' script to build your chroot, you can pass it --eatmydata, which will help a lot. The tests run zookeeper, which fsyncs every write to disk. --eatmydata sets up your schroot to run everything inside 'eatmydata' which disables fsync and so de-couples your build from having to flush to disk. 2) If you have access to a machine with an SSD, that also helps a lot. On a non-SSD box, the tests take 7 minutes. With eatmydata, that drops to 5. With an SSD machine those numbers are cut in half. Thus, each tests is faster and so has less chance to cross over 5 seconds. Anyway, I think this is worth re-titling to test suite fails sporadically and mark as an upstream bug. ** Summary changed: - FTBFS: Sveral tests fails + Juju test suite fails sporadically due to low timeouts ** Changed in: juju (Ubuntu) Status: Confirmed = Triaged ** Also affects: juju Importance: Undecided Status: New ** Changed in: juju Status: New = Confirmed ** Changed in: juju (Ubuntu) Importance: Undecided = Medium ** Changed in: juju Importance: Undecided = Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to juju in Ubuntu. https://bugs.launchpad.net/bugs/1017113 Title: Juju test suite fails sporadically due to low timeouts To manage notifications about this bug go to: https://bugs.launchpad.net/juju/+bug/1017113/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

fwiw, i'm experimenting atm with a small test runner change/diff to disable zk fsync http://paste.ubuntu.com/1057627/ -k On Sun, Jun 24, 2012 at 10:58 AM, Clint Byrum cl...@fewbar.com wrote: Hi Martin.
