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.

Crontabs live in a branch on devpad:/code/pqm/crontabs/launchpad-production/ (look at the loganberry-launchpad file).

Caveats

• 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.

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
