	Subject: Summary of this week's deployment of 1.36.0-wmf.36

	This is a summary of this week's deployment of the 1.36.0-wmf.36
	branch of MediaWiki and its extensions. The primary person in charge
	this week is Antoine Musso, with Ahmon Dancy as backup, both from the
	Release Engineering team.

	The summary task for this week is
	https://phabricator.wikimedia.org/T274940

	This week's deployment was not successful. The train got to group 2,
	but had to be rolled back all the way to group 0, which is where it is
	at right now. The current problems are:

	- T278478: FlaggedRevs: PHP Notice: Undefined index: status
	https://phabricator.wikimedia.org/T278478

	- T278429:
	Translate\PageTranslation\ParserOutput::sourcePageTextForRendering()
	must be an instance of Language, instance of StubUserLang given
	https://phabricator.wikimedia.org/T278429

	- T277795: User not found by actor ID: [id]
	https://phabricator.wikimedia.org/T277795

	The general policy is to NOT deploy on Fridays. If we deploy something
	on a Friday and the sites break on Saturday, multiple people may need
	to be alerted to diagnose and fix or work around the problem. Thus,
	when fixes are found, we tend to deploy them on Monday instead. Then,
	on Tuesday, the next train can start.

	Issues that have already been dealt with along the week:

	- T277722: TypeError: this._languageCodes is undefined at
	getLanguageNameMap
	https://phabricator.wikimedia.org/T277722

	- T278375: Class 'GlobalUsageHooks' not found
	https://phabricator.wikimedia.org/T278375

	- T278379: Argument 1 passed to
	ProofreadPage\Index\IndexTemplateStyles::__construct() must be an
	instance of Title, null given, called in
	/srv/mediawiki/php-1.36.0-wmf.36/extensions/ProofreadPage/includes/Page/PageContent.php
	on line 284
	https://phabricator.wikimedia.org/T278379

	- T278400: PHP Warning: array_key_exists(): The first argument should
	be either a string or an integer
	https://phabricator.wikimedia.org/T278400

	We saw some people highlight especially risky patches in the week's
	summary task. That was very welcome! Thank you, Amir Sarabadani and
	Roan Kattouw.

	As usual, a whole bunch of people helped to find, triage, analyze,
	fix, or work around problems this. Release Engineering thanks
	everyone, without help we wouldn't be able to deploy MediaWiki.
