Of course, as happens sadly often, the scope creeps.. Additional pain points Zope’s test runner runs things that are not tests, but which users want to know about – ‘layers’. At the moment these are reported as individual tests, but this is problematic in a couple of ways. Firstly, the same ‘test’ runs on multiple […]


Subunit is seven and a half years old now – Conrad Parker and I first sketched it up at a CodeCon – camping and coding, a brilliant combination – in mid 2005. revno: 1 committer: Robert Collins <robertc@robertcollins.net> timestamp: Sat 2005-08-27 15:01:20 +1000 message:  design up a protocol with kfish It has proved remarkably resilient […]


Recently I’ve been doing my personal development SSH’d into my personal laptop. I found that launchpadlib (which various projects use for release automation) was failing – the gnome keyring API threw an error because the keyring was locked, and python-keyring didn’t try to unlock it. I needed a workaround to be able to release stuff, […]


I recently added a formal interface to testrepository to enable cross-machine scaling of test runs. As testrepository is still a static scheduler, this isn’t perfect, but its quite a minimal interface, which makes it easy to implement. I will likely evolve it in reaction to feedback and experience. In the long term I’d love to […]


Thanks to Corey Goldberg, one of my colleagues @ Canonical, the page performance report can now be used on regular Apache log files, rather than just the zserver trace log files that Launchpad’s middle tier generates. We use this report to identify poorly performing pages and get insight into the timing patterns of bad pages. […]


A while back mdz blogged about challenges facing Ubuntu and other Linux distributions. He raises the point that runtime libraries for Python / Ruby etc have a unique set of issues because they tend to have their own packaging systems. Merely a month later he attended Debconf 2010 where a presentation was given on the […]


Edits: Corrected the description of the slony bug, and noted that there is a typo on the lazr_postgresql PYPI page. Two years ago Launchpad did schema changes once a month. Everyone would cross their fingers and hope while the system administrators took all the application servers offline, patched the database with a months worth of […]


This is largely a memo-to-my-future self, but it may save some time for someone else facing what I was last weekend. I’ve been putting together a Reprap recently, seeded by the purchase of a partially assembled one from someone local who was leaving town and didn’t want to take it with them. One of the […]


My laptop has somewhat less than 1/2 the grunt of my desktop at home, but I prefer to work on it as I can go sit in the sun etc, very hard to do that with a mini tower case :) However, running everything through ssh to another machine makes editing and iterating more clumsy; […]


I’ve made the Testtools committers team own both the project and the trunk branch for both pyjunitxml and testscenarios. This removes me as a SPOF if anything needs doing in those projects – any Testtools committer can now do it. (Including code review and landing). If you are a testtools committer and need PyPI release […]
