Hi, I took a look at replacing Britney's installability tester[1]. In my follow up mail I will attach my patches[2]. Part of my focus has been to implement this as a(n almost) compatible replacement for the old module. Result-wise it gives identical results to our current implementation in the test suite. Speed-wise, I believe it is "fast enough" to be used. I have some ideas for further optimization, though these will most likely imply structural changes to other parts of Britney. My testing suggests that using Python2.7 will greatly affect the runtime with this module. The master branch correctly only see a similar improvement in one of the live-data samples[3]. Please note that the britney-tests repository is currently not setup to use the live-data as regression test. If you want to verify my results, consider using "test-branch" to pit it against the master branch. ~Niels [1] The "dark corner" written in C that no ones ever looks at if they can avoid it. [2] I do not trust myself with reportbug to get it right in this email. :) [3] Runtimes the master branch vs my branch. The "-py2.6" marker means Python2.6 was used as interpreter. Same for "-py2.7" and Python2.7. +------------+--------------+--------------+--------------+--------------+ | live-data | master-py2.6 | master-py2.7 | branch-py2.6 | branch-py2.7 | +------------+--------------+--------------+--------------+--------------+ | 2011-12-13 | 201.363s | 186.369s | 173.224s | 135.778s | | 2011-12-20 | 97.947s | 93.213s | 142.128s | 111.234s | | 2012-01-04 | 74.255s | 70.503s | 117.565s | 95.287s | +------------+--------------+--------------+--------------+--------------+ NB: 2011-12-13 triggers an AIEEE in the master branch. -- To UNSUBSCRIBE, email to debian-release-requ...@lists.debian.org with a subject of "unsubscribe".
