About "Let's make sure"... which team or who would be a good candidate for this? I'm trying to discern whether this is a task for Developer Relations or for someone else to work on first.

@Aklapper As you can see, I mostly focus on this kind of requests because they're easy for me and I understand what I have to do, most of the times :) I'm happy to continue if you don't mind. Thanks.

Heh, of course I do not mind and your contributions are more than welcome and I don't want to stop you at all. :)
I'm more after broadening the contributor base and I don't want people to burn out at some point...

Anybody who knows what they are doing™ when writing such patches? :)
(Could be moved to Team-Radar on the workboard for the time being.)

Moving this task to Developer-Advocacy team radar without any other project associated is prone to make this task missed by the people who can fix it. I am adding Wikimedia-Site-requests in case it helps.

Here are my notes so far:

== General process ==
* Need LDAP account for Gerrit, use of file editing and git over SSH, basic PHP knowledge

Maybe we could put it at https://wikitech.wikimedia.org/wiki/Wikimedia_site_requests

Some quick links, comments etc:

Thanks for going through this. A lot of your notes are useful URLs that we should attempt to use in this page instead of duplicating everything, and risking more outdated pages when things change.

For people processing these patches instead of just creating them: Deployment group in gerrit, deployment access on the servers (set by modules/admin/data/data.yaml in the operations/puppet repository, link how to get shell access page)

I probably did this off the top of my head, I meant [[How to deploy code]]: https://wikitech.wikimedia.org/wiki/How_to_deploy_code

Yes, but note that some of those examples are not much use in the Wikimedia MW setup (due to our particularly complex config) and I would not just take the SQL on that page and dump it into a production master DB server :)

We should probably note the difference between Wikimedia-configured namespaces and extension namespaces here.

Yep.

No, at least that's not what I had in mind. Honestly I might not go into the complex social/governance aspect in this page.
We should link to the extension review checklist/queue(?) here.

The sections about InitialiseSettings and CommonSettings would be useful for the "wmf-config/(Initialise|Common)Settings.php" item in the general process section of this. I would expect the part about extensions would be relevant to our "Enabling/disabling extensions"
Note that the page is marked outdated and I have not read it in detail.

This project is selected for the Developer-Wishlist voting round and will be added to a MediaWiki page very soon. To the subscribers, or proposer of this task: please help modify the task description: add a brief summary (10-12 lines) of the problem that this proposal raises, topics discussed in the comments, and a proposed solution (if there is any yet). Remember to add a header with a title "Description," to your content. Please do so before February 5th, 12:00 pm UTC.

Note: Namespace localization can require separate patches in quite some repositories. See e.g.

• https://gerrit.wikimedia.org/r/#/c/348112/ in MediaWiki Core.
• https://gerrit.wikimedia.org/r/#/c/348114/ in Gadgets extension.
• https://gerrit.wikimedia.org/r/#/c/348113/ in Scribunto extension (for 'Module:`)

I'm afraid there might be even more spots?

Edit: ....and to deploy a custom namespace only on Wikimedia sites (and not in the MediaWiki software for everybody), the file to change is wmf-config/InitialiseSettings.php in the repository operations/mediawiki-config.

Namespace localization must happen in whatever extension the namespaces is belonging to. At some point Translatewiki could do it via a special page but it has been broken for a long time.

A special mention about logo sizes and optiPNG settings would be good. I am mostly doing optiPNG -o8 but I've seem -o7 sometimes. Does that make a huge difference?

This would be pretty useful to anyone passing by who feels like picking up a task or two - I've started with the IP throttle exception over at Wikimedia site requests, and will try to add a few more.

I think the Associated configuration file --> Process --> Example layout is rather helpful - any thoughts?

Could this become a good pool of first tasks for new developers and/or Google Code-in students?

@Qgil: Documenting is probably not a good GCI task because you need to have a complete understanding where to do which things (see e.g. T126330#3217387).
And I still struggle in some areas after all those years...

@Majavah just started working on site requests as a new volunteer, maybe they have some insight on what needs to be better documented.

Thanks for the ping, I'll take a look tomorrow.

I will drop a plug here for getting the last couple of features for https://www.mediawiki.org/wiki/Extension:ThrottleOverride implemented so we can start the security review and deployment process for it. See MediaWiki-extensions-ThrottleOverride for open tasks.
