Testing

  • Use wikitest.g.o site as staging area for MediaWiki stable releases.
  • Check system requirements for release.
    • Check present version: php --version
    • Update PHP to latest stable release (if necessary). Create docs on Infra wiki for this task.

Pre-update checklist

Download, verify, decompress update file(s)

  1. Download the latest release (or the appropriate patch) and associated signature to the work directory.

Create backups

  1. Create a database export/backup (SQL and XML) of the current wiki on the database cluster. See the infrawiki's runbook for more details here.
  2. Backup current htdocs, copy wiki images to wikitest, then copy wikitest htdocs to updated:
    • htdocs: tar --create --preserve-permissions --xz --xattrs-include='*.*' --acls --verbose --file gentoowiki.tar.xz --directory /path/to/directory/ .

Apply update(s)

  1. Apply release:
    • TODO
  2. Apply patch:
    • patch -p1 --dry-run -i mediawiki-1.35.7.patch.gz
    • Apply the patch: patch -p1 -i mediawiki-1.35.7.patch.gz
      • Check Special:Version to see the version has been updated to the same version as the patch.
    • Apply database update: php maintenance/update.php
