Work has begun to upgrade the base distribution for MediaWiki-Vagrant to Debian Stretch [0]. The Wikimedia production cluster is preparing for a similar upgrade [1] which will in part allow the Wikimedia wikis to migrate to PHP 7 [2].

== What's new in the stretch-migration branch? ==

• Debian Stretch (Debian 9) base image
• Default PHP runtime is Zend PHP 7.0 (HHVM available via role)
• Database is MariaDB 10.1
• Provisioning via Puppet 4

Setting up a basic wiki (no roles enabled) seems to work pretty well. Additional roles need testing and may require updated Puppet manifests (Puppet syntax updates, erb syntax updates, package name changes, additional packages). Help is needed to test roles, file bugs, and submit patches. With some help I think we can be ready to switch to Stretch as the default base image in early/mid January.

== Testing the Stretch base image and Puppet profiles ==

Its recommended to test with a fresh MediaWiki-Vagrant checkout so if things go badly you can easily switch back to your original install and keep working.

$ git clone --recursive https://gerrit.wikimedia.org/r/mediawiki/vagrant mwv-stretch $ cd mwv-stretch $ git checkout stretch-migration $ ./setup.sh $ vagrant up

You can run `vagrant roles list -e -1` to get a nice list of the roles you have enabled on your normal Trusty VM install to copy over to your Stretch testing VM. This one-liner liner might even do it for you:

$ cd mwv-stretch $ vagrant roles enable $(cd ../vagrant; vagrant roles list -e -1) $ vagrant provision

Work has gone pretty well on the stretch-migration branch. I'd like to merge the branch to master and make it the default experience on or around 2018-01-18. Having a major feature branch like this alive for more than a month makes integrating the changes more difficult. It also makes things harder for people who are making improvements on the master branch.

It would be great to have some more users testing it out to make sure the roles that they need to work with MediaWiki-Vagrant day to day are working there. Special thanks to Stas, Gilles, Hashar, and Željko for the bug reports and patches that they have already supplied.
