Packaging Wikidiff2

Tarball must be available in https://releases.wikimedia.org/wikidiff2/ as described in https://www.mediawiki.org/wiki/Wikidiff2/Release_process and we need to get the source code to a builder machine. Here is a workflow that worked for us in the past:

• ssh to a random app server
  • $ apt-get source wikidiff
• scp to a builder machine (currently deneb.codfw.wmnet) and copy the tarball to it, and run
  • $ uupdate ../wikidiff-1.2.3.tar.xz
• it will generate a new directory named wikidiff-1.2.3 which will update the package to the new tarball
• bump the version to something like 1.2.3.4~wmf1 by running
  • wikidiff-1.2.3$ dch -i
• And build for <distro>-wikimedia. Lastly, tell pbuilder to use our php72 component. For example:
  • PHP72=yes ; DIST=stretch-wikimedia pdebuild
• Upload using the instructions in Debian Packaging#Upload to Wikimedia Repo

Rolling out

1. Install on beta cluster, remember to run systemctl restart php7.2-fpm
2. Ask stakeholders to ensure it works
3. Rollout to canary servers (cumin/debdeploy aliases A:mw-app-canary and A:mw-api-canary) for at least one day
4. Rollout to all servers using debdeploy
