LocalisationUpdate

Purpose

This MediaWiki extension fetches updates to MediaWiki core and extension localisation files and makes them available to an installation without updating its own source. This allows us to pull updated translations being committed to development trunk even though our live install is running wmf-deployment branch.

Source

• http://www.mediawiki.org/wiki/Extension:LocalisationUpdate

Where it runs

• hume
  • run l10nupdate every 24h at 2am GMT to update master cache files (can be sped up if desired)
    • Must be on a mediawiki-installation host with access to /home and a SVN client.
• all mediawiki-installation boxes
  • Update wmf-deployment/cache/l10n directory from NFS master every day at 3am GMT (Cron setup by Puppet)

Batch frequency

• not yet set up; planned daily?

How it works

Batch job in /home/wikipedia/bin/l10nupdate. Does roughly:

 echo "Starting l10nupdate at `date`."
 svn up /home/wikipedia/l10n/trunk/phase3
 svn up /home/wikipedia/l10n/trunk/extensions
 php /home/wikipedia/common/wmf-deployment/extensions/LocalisationUpdate/update.php \
   --wiki=aawiki \
   --outdir=/home/wikipedia/common/wmf-deployment/cache/l10n \
   --all
 echo "Completed."

Files will be updated in /h/w/wmf-deployment/cache/l10n; Apache clients should sync updates from that every 24 hours or at scap time.

Files

• /home/wikipedia/l10n/trunk
  • MediaWiki checkouts of trunk phase3 and extensions
• /home/wikipedia/common/wmf-deployment/cache/l10n
  • Storage for serialized updates
• /apache/common/wmf-deployment/cache/l10n
  • Synced home of serialized updates per web server

Config

In MW config:

• $wmgUseLocalisationUpdate (to enable/disable ext load)
• $wgLocalisationUpdateSVNURL = '/home/wikipedia/l10n/trunk'
• $wgLocalisationUpdateDirectory = '/apache/common/wmf-deployment/cache/l10n'
