Smells like something is not being cached. Language::getCompiledPluralRules(), which is called just before evaluateCompiled(), should always return an array, and that's not the case here.

It's dropped a couple of lines

PHP Catchable fatal error: Argument 2 passed to CLDRPluralRuleEvaluator::evaluateCompiled() must be an array, null given, called in /usr/local/apache/common-local/php-1.23wmf19/languages/Language.php on line 4592 and defined in /usr/local/apache/common-local/php-1.23wmf19/languages/utils/CLDRPluralRuleEvaluator.php on line 72

The only way I can see this happening is by constructing Language object with code which is not invalid, but not valid according to Language::isValidBuiltInCode. This code does not have plural rules, and fallbacks return empty array in that case, which means $pluralRules is null and that is a fatal error.

Still thinking what would be suitable course of action.

I’m seeing this error as well in MediaWiki 1.23.0rc0.

PHP Catchable fatal error: Argument 2 passed to CLDRPluralRuleEvaluator::evaluateCompiled() must be an array, null given, called in /srv/www/mediawiki/public_html/w/languages/Language.php on line 4612 and defined in /srv/www/mediawiki/public_html/w/languages/utils/CLDRPluralRuleEvaluator.php on line 73

Since Niklas mentioned caching, I will also note that I’m occasionally seeing this error from runJobs as well:

PHP Notice: unserialize(): Error at offset 0 of 27 bytes in /srv/www/mediawiki/public_html/w/includes/cache/LocalisationCache.php on line 1298
PHP Notice: unserialize(): Error at offset 0 of 11 bytes in /srv/www/mediawiki/public_html/w/includes/cache/LocalisationCache.php on line 1298

They don't happen in the same runJobs instance though.

That sounds like your localisation cache is outdated. I expect all errors go away if you run: php maintenance/rebuildLocalizationCache.php --force

Jamie, Sam: are you still seeing this or can this be closed?

Nikerabbit added a comment.Oct 21 2014, 12:44 PM

I am not seeing this in the WMF logs anymore.
