In case anyone has just had a heartattack from all the timeout bugs I've filed ... read on :)
We have a top timeout report that we get daily. Sadly, there are a few problems with this - its noisy - very very noisy. Things are grouped badly so we see unrelated issues clumped together, and the same issue will be shown many different times. There are bugs open to fix that, but the underlying theory is a bit suspect [for the use case of 'find things that timeout to fix'. Stuarts new page performance report provides a different set of data, one that is very useful for determining both things timing out and things likely to start timing out - but without the detail needed to fix things (which the daily oops reports give). So, i've run through the top-list of the page performance report (I attached a copy of one the other day), and ensured there were bugs for all of the high probability pages in the report. That is, if the page regularly (>1%) exceeds our timeout threshold on edge or production, I've made a bug for it. My goal in doing this was to provide a complete view of the danger-pages : rather than facing a never-ending pile of work which bubbles up as we fix things in the daily oops report, capturing the full set lets us sensibly burn down all the timeouts affecting us today and get in a solid position for lowering our back-stop timeout configuration. It also lets folk like me that like to pick a timeout to fix to be working on a somewhat pre-massaged dataset. And the good news is that the total count is *only* 66 bugs - https://bugs.edge.launchpad.net/launchpad-project/+bugs?field.tag=timeout. I honestly expect *nearly all* timeout reports we'll get until we change the timeout again will be either one of these bugs or a transient condition (like running on reduced DB server capacity during node upgrades to lucid). -Rob _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
