Scrum of scrums/2018-01-10

From mediawiki.org

Callouts

[edit]
  • Search PF would like somebody from performance/MediaWiki team to look at: https://phabricator.wikimedia.org/T183101 we’ve got some fails on LinksUpdate which blocked search index update which makes Wikidata items invisible in search (~50 items)
    • [Perf] We've been looking at it, but we haven't identified a cause for this issue yet.
    • [SP] I guess we will just watch out for it and hope it was an one-time thing.
  • [Perf] Trying to compile a list of everything running in Prod that requires Zend PHP5. Currently only aware of the XML dump job (has syntax errors in output if run under HHVM). Anything else, please reach out to Ian (email: imarlier@, irc: marlier)
  • Reminder: Whitelist your EventLogging schema if you want data older than 90 days to be retained, talk to the Analytics team if you're not sure what this means
