launchpad development
Purpose
This page documents the schedule of automatic translations tarball exports from Launchpad to be used as a source to langpack-o-matic to create the Ubuntu language packs.
Current export schedule (as of 2010-06-29)
Note: these are the starting days of the exports. The cron jobs to start generating the language-pack tarballs start on these days. Then langpack-o-matic picks them up the next day.
- Export starts: 22:00 UTC
- Build starts: 14:00 UTC next day
NOTE: THE TABLE REFLECTS A PROPOSAL FOR THE NEW SCHEDULE FOR NATTY NARWHAL. AS SUCH, IT IS NOT YET FINAL. THE PROPOSED EXPORTS AND LANGUAGE PACK BUILDS ARE SHOWN IN BOLD NEXT TO THE CURRENT ONES

Notes
- We should avoid generating language packs on Wednesdays, which are Launchpad rollout days
- If language pack generation on Tuesdays take longer than usual (say 10h), we might even hit our early Wednesday rollouts and language packs might not be generated.
- The timing is chosen so we hit the times when we usually expect the lowest load. Most of the translation work happens in Europe, South America and Asia, and 22:00 UTC should mean less load on LP due to translation activity. With DB slaves, though, this is probably not something we should worry about.
Launchpad crontabs live in a branch on devpad:/code/pqm/crontabs/launchpad-production/ (look at the loganberry-launchpad file).
