Changing my shell preference
by Huji Lee 31 Jan '18

31 Jan '18

Is there a way to change my preferred shell on the Clouds to zsh? When I try chsh -s `which zsh` it asks for a password, which I don't have of course. Thanks, Huji

Get my DB to hold connection settings
by Maximilian Doerr 20 Jan '18

20 Jan '18

I just can’t figure this out. Whenever I try to set the my.cnf in my personal DB instance to increase max connection and reduce max idle timeouts, they won’t appear when the DB is restarted. I always have to set them directly in the DB CLI. Can somebody explain to me what I’m doing wrong? I was meaning to address this sooner but seeing as how the instance was never in need of a reboot until Andrew did made forget to address this issue.

Let's discuss Growing the MediaWiki Technical Community (Dev Summit)
by Matthew Flaschen 18 Jan '18

18 Jan '18

At the Dev Summit, Birgit Müller and I will run a session on Growing the MediaWiki Technical Community. If you're attending, we hope you will consider joining us. Everyone (attending the Dev Summit or not) is welcome and encouraged to participate at https://phabricator.wikimedia.org/T183318 (please comment there, rather than by email). We are discussing the following questions: * What would allow you to develop and plan your software more efficiently? * What would make software development more fun for you? * What other Open Source communities do we share interests with? * How can we change our processes to take technical debt more seriously? "Develop" means any kind of work on a software system, including design, documentation, etc. Our topics are: * Better processes and project management practices, integrating all developers and allowing them to work more efficiently * Building partnerships with other Open Source communities on shared interests (e.g. translation, audio, video) * Reducing technical debt Matt Flaschen

Emulate cross-wiki joins
by Federico Leva (Nemo) 18 Jan '18

18 Jan '18

I usually use bash or python scrips to query data from multiple wikis at once, but I wanted something "simple" in Quarry such as a list of users who are active in two wikis, and I felt very stupid. I ended up using two separate queries, a subquery and a mix of GROUP_CONCAT, TO_BASE64 and SET SESSION group_concat_max_len (to make a sort of temporary table in a pseudo-array string): https://quarry.wmflabs.org/query/23956 This was reasonably fast, but is there a better way?

[Cloud-announce] Meltdown reboots and maintenance continued
by Chase Pettet 17 Jan '18

17 Jan '18

We have completed all of the updates and reboots for the hypervisors and instances in https://phabricator.wikimedia.org/T184910, but there are more maintenance events that are less invasive to come. This is being tracked in https://phabricator.wikimedia.org/T184910 Most of this will be handled gracefully without user impact, but not all of it. We will reboot the `dumps` NFS server that also provides the `maps` and `scratch` NFS shares tomorrow (1/18/2018). Note the reason this is an outage event is that this server is a single point of failure. Efforts to improve this are happening in https://phabricator.wikimedia.org/T168486. More announcements will come for maintenance that is impactful. -- Chase Pettet chasemp on phabricator <https://phabricator.wikimedia.org/p/chasemp/> and IRC _______________________________________________ Wikimedia Cloud Services announce mailing list Cloud-announce(a)lists.wikimedia.org (formerly labs-announce(a)lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/cloud-announce

[Cloud-announce] Maintenance reboots upcoming
by Andrew Bogott 16 Jan '18

16 Jan '18

Sometime soon (probably in the next day or two) we will be applying kernel patches to all VMs and physical hosts in WMCS. This is to address an urgent security issue[1] , so we'll be skipping the traditional 7-day warning period -- basically as soon as proper fixes are available we'll start patching and rebooting. As usual, we'll do our best to re-balance Toolforge grid nodes, so impact on Toolforge users should be minimal (worst case you may need to manually restart interrupted tasks). For other users: if your VPS project requires special handling or specific notice about when a particular VM will reboot, please add a subtask describing your need to https://phabricator.wikimedia.org/T184189 .

MediaWiki-Vagrant's master branch migrated to Debian Stretch
by Bryan Davis 15 Jan '18

15 Jan '18

I have just merged the "stretch-migration" feature branch to master for MediaWiki-Vagrant. Major changes: * Debian Stretch (Debian 9) base image * Default PHP runtime is Zend PHP 7.0 (HHVM available via role) * Database is MariaDB 10.1 * Puppet 4 Once you update your local MediaWiki-Vagrant clone to 59e3b49c or later you will need to create a new VM based on the Debian Stretch base image in order to use `vagrant provision`. Upgrading your local VM may be as easy as using `vagrant destroy` to delete the current VM followed by `vagrant up` to make a new one. Note that this will *not* save the contents of any local wikis in the VM. You will need to manually backup and restore the databases or export and import pages you have created. See <https://phabricator.wikimedia.org/T181353> for more information and a few known open bugs. I have also created a jessie-compat branch that can by used by users who are not ready to destroy their current Jessie based virtual machines and start over with Stretch. A simple `git checkout -b jessie-compat` should be all that is needed to switch your local MediaWiki-Vagrant clone to the new compatibility branch. This branch will probably receive few updates, so you are encouraged to create new Stretch based VMs soon.
