== Callouts ==
* '''Data Centre Switch''' The Wikimedia Foundation will be testing its
secondary data centre. This will make sure that Wikipedia and the other
Wikimedia wikis can stay online even after a disaster. To make sure
everything is working, the Wikimedia Technology department needs to do a
planned test. This test will show if they can reliably switch from one
datacenter to the other. It requires many teams to prepare for the test and
to be available to fix any unexpected problems. They will switch all
traffic to the secondary data centre on Tuesday, September 1st 2020. More
information:
https://lists.wikimedia.org/pipermail/wikitech-ambassadors/2020-August/002344.html
* '''No train next week''' There is a planned switchover to our secondary
datacenter scheduled for Tuesday, September 2nd 2020. To avoid creating
problems for our SREs we'll be skipping the train for next week -- the week
of 2020-08-31 -- and not doing any deployments the day of the switchover --
2020-09-01.
* '''scap sync now called scap sync-world''' There is a new release of Scap
(3.15.0), which will be installed on the various servers next week. More
information:

[Wikitech-l] Tech Com Board Grooming 2020-08-26

[Dan Andreescu]

Activity since Monday 2020-08-26.

https://phabricator.wikimedia.org/tag/techcom/
https://phabricator.wikimedia.org/tag/techcom-rfc/

Committee inbox: none

Committee board activity:

   - Timo updated T253461 Liberate the @ for AtEase
   

New RFCs:

   - Created / closed / opened / closed all since last week: T261133 Ban IP
   edits on pt.wiki .  Basically
   this was a policy discussion, not a technical RFC

Phase progression: none

IRC meeting request: none

Other RFC activity:

   - Discussion spawned from T240884 (evaluate user-provided regex)
    to T260330 (the PHP service
   Tim's building)  around
   encoding parameters, security, and more
   - Product Data Engineering team shows interest in resourcing RFC: Better
   interface for generating metrics in MediaWiki
    (that would be an
   interesting centralization of all things "metrics", whether system level or
   high level)
   - Development starts on RFC: Parsoid Extension API
   



NOTE: The technical committee is hoping for wider and less formal
participation, starting with this message.  Feel free to chime in, we'll
start a meta-thread about this soon.

Re: [Wikitech-l] Wikimedia GitHub OAuth restrictions enabled

[Martin Urbanec]

Hey, the task is restricted one. Is that the intention?

[Wikitech-l] scap sync now called scap sync-world

[Lars Wirzenius]

Hi,

I tagged a new release of Scap (3.15.0) yesterday, which will
hopefully be installed on the various servers next week. One of the
changes is that "scap sync" now gives and error, and directs the user
to use "scap sync-world" or "scap sync-file", depending on what they
meant to do.

This change was made because Release Engineering had noticed that
people accidentally run "scap sync" when they meant "scap sync-file".
We decided to have a "flag day"[0] for this because merely warning
about using "scap sync" is very easy to miss, especially if in an
automated system somewhere. We also assume this is not actually used a
lot, and mostly interactively, in which case the error message is
hopefully clear enough to guide the user in the right direction.

 [0] https://en.wikipedia.org/wiki/Flag_day_(computing)

We've fixed and are fixing places in scripts and CI jobs that we know
of where "scap sync" is used. If you find more, please report them to
https://phabricator.wikimedia.org/T250302 .

Sorry about any inconvenience.
