subunit version 2 progress
Subunit V2 is coming along very well. Current status: I have a complete implementation of the StreamResult API up as a patch for testtools. Thats 2K LOC including comeprehensive tests. Similarly, I have an implementation of a StreamResult parser and emitter for subunit. Thats 1K new LOC including comprehensive tests, and another 500 lines of […]

StreamResult, covered in my last few blog posts, has panned out pretty well. Until that is, that I sat down to do a serialised version of it. It became fairly clear that the wire protocol can be very simple – just one event type that has a bunch of optional fields – test ids, routing […]

My last two blog posts were largely about the needs of subunit, but a key result of any protocol is how easy working with it in a high level language is. In the weekend and evenings I’ve done an implementation of a new set of classes – StreamResult and friends – that provides: Adaption to […]

More subunit needs
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 […]

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 […]

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 […]
