Extension:CommonsMediaCaching

TODO documentation

This extension reads all new thumbs (from commons.wikimedia.org/wiki/) in the wiki media or image folder an if they are new it downloads them to a local specified Wiki or repository Wiki (OpenMedia).

(1) Set up a cronjob for runJobs.php

TODO documentation For instance in a file like /etc/cron.d/wiki-run-jobs you can specify how often the job should run the maintenance script runJobs.php

# RUN every 5 minutes  mediawiki Jobs: Species-ID, Offene Naturfuehrer, etc
# NOTE: without  &> /dev/null it will create mails to www-data!
3,8,13,18,23,28,33,38,43,48,53,58 * * * * www-data bash /usr/share/mediawiki26/extensions-rich-features/CommonsMediaCaching/runJobs.sh &> /dev/null 
1,6,11,16,21,26,31,36,41,46,51,56 * * * * www-data bash /usr/share/mediawiki26/extensions-simple-features/CommonsMediaCaching/runJobs_simple-extensions.sh &> /dev/null

The script …

• extensions-rich-features/…/runJobs.sh contains all Wikis with extended extension set up
• and extensions-simple-features/…/runJobs_simple-extensions.sh for those with a simple extension setup.

(2) Logrotate for runJobsOutput.log

Set up logrotate, eg. with a configuration in /etc/logrotate.d/wiki-runJobs

/usr/share/mediawiki26/extensions-rich-features/CommonsMediaCaching/runJobsOutput.log {
  missingok
  compress
  delaycompress
  daily
  size 1M
  create 644 www-data www-data
  rotate 10
}
/usr/share/mediawiki26/extensions-simple-features/CommonsMediaCaching/runJobsOutput.log {
  missingok
  compress
  delaycompress
  daily
  size 1M
  create 644 www-data www-data
  rotate 10
}

Set up a template in the local (repository) Wiki

Template:Cached Commons Copy is used on File pages to store the information of the original commons file. It can look like this:

<noinclude>A simplified version of [[Template:Cached Copy]] (see there), specific to Wikimedia commons. It also adds a new parameter: lastuploader  

The parameters are simplified to only:
* '''file=''' (without the File: prefix)
* '''lastuploader''' =for the name of the last user uploading this file on commons (not sufficient for licensing and attribution purposes, this user may only have modified someone elses original work.
* '''time=''' (optional).

Example: <nowiki>{{Cached_Commons_Copy|file=x.jpg|lastuploader=xxuser|time=2011-08-23 : 20:12}}</nowiki> results in:

{{Cached_Commons_Copy|file=x.jpg|lastuploader=xxuser|time=2011-08-23 : 20:12}}
