[Wikitech-l] MediaWiki development images now published from deployment pipeline

[Brennen Bearnes]

Hey all,

Just a quick announcement that we (Release Engineering) are now
publishing Docker images[0] for mediawiki/core from Zuul's postmerge
pipeline.  At present, the image built from the most recent merge to
master is always tagged "dev".

These images are intended for use with local-charts[1], and make some
assumptions specific to that environment.  I hope to make them more
generally usable in the long run.

Images are built from specifications in .pipeline/config.yaml[2] and
.pipeline/blubber.yaml[3].

Please let me know if you have any concerns or questions!

[Wikitech-l] Announcing: First Quarterly Technical Community Newsletter!

[Sarah R]

Hi Everyone,

We’re happy to announce the launch of the brand new quarterly Technical
Community Newsletter
. The
newsletter is compiled by the Wikimedia Developer Advocacy Team. It aims to
share highlights, news, and information of interest from and about the
Wikimedia technical community.

The First Edition of the Technical Community Newsletter

launches today! Find out more about what technical contributors have been
up to this past quarter, upcoming conferences & calls for papers, and how
to get involved.

Like all good things, the first edition starts as a prototype. Some ideas
we had in mind for additional sections/categories are “Tool of the Season”,
“Wikimedia in numbers” (i.e. around code review, new developer accounts,
etc). Ideas about what you would like to see and highlights you would like
to share are welcome
!

Subscribe to the Technical Community Newsletter
,
if you'd like to keep up with essential updates and information.

Kindly,

Sarah R. Rodlund
Technical Writer, Developer Advocacy

[Wikitech-l] TechCom Radar 2019-10-02

[Alexandra Paskulin]

Hi all,

Here are the minutes from this week's TechCom meeting:

* Approved: Drop IE6 and IE7 basic compatibility and security support
. This RFC removes IE6 and IE7
from "basic" support
in the MediaWiki compatibility table.

* Discussed: Core REST API namespace and version <
https://phabricator.wikimedia.org/T232485>.
This RFC proposes a namespace and version policy for routes in the
MediaWiki REST API.

* Discussed: Section header "share" link <
https://phabricator.wikimedia.org/T18691>.
This RFC aims to make it easier for readers to share links to sections on
wiki pages.

* Discussed: Serve Main Page of Wikimedia wikis from a consistent URL
. This RFC proposes serving a
wiki’s main page from
the domain root. The configuration option has been merged as disabled by
default, and discussion
with stakeholders is ongoing.

* No IRC meeting next week.

You can also find our meeting minutes at

Best,

For instance, you could call the `::execute()` method on a class that
extends SpecialPage directly. It might be helpful to know what you are
trying to do though.

Basically what Gergo said. :)

Re: [Wikitech-l] 503 Backend fetch failed

[Bináris]

It becomes more and more frequent in the last couple of days. This time I
ran into the error in the web browser and got a copyable error message:

If you report this error to the Wikimedia System Administrators, please
include the details below.

Hi Jeroen,

If you're asking for examples of Selenium tests, take a look at:

That's pretty much how I would try it (if I couldn't avoid testing the full
web stack instead of just calling the relevant special page or action
directly).
