Wikimedia Platform Engineering/MediaWiki Core Team/Check-ins/20131209

who: Brad, Dan, Nik, Tim, Bryan, Chad, Greg, Chris, Ori, Howie

bugzilla:58042 - Certain entries in parser cache on ca.wikipedia.org do not have Tidy enabled
- Chad will look, make sure it’s not Cirrus
How much do we care about weird old distros?
- MediaWiki requires PHP 5.3.2, which was released 4 March 2010. But apparently CentOS 5 has a version of 5.3.3 compiled against really old versions of other libraries.
- bugzilla:58178 - 1.22 needs curl >= 7.16.2 (released 11 April 2007)
- bugzilla:58213 - 1.22 needs pcre >= 7.2 (released 19 June 2007)
  - Rough consensus: bail out in the installer if it’s hard to workaround. For 1-line workarounds, just workaround

bugzilla:57550, bugzilla:58088 - Tim review?
CleanChanges. Nemo asked to have it reenabled on Meta as it allows filtering RecentChanges by language which helps with translation work. Ideally it’d make sense to Core-ify that language filtering rather than re-enabling CleanChanges. Thoughts?

  - Send email to Erik and MediaWiki core list about this
gerrit:90263 - Move AssertEdit into core. Patch is good, but we need to undeploy AssertEdit at the same time. Reedy?
- switch based on version
- Greg to ping Reedy

Draft Puppetization of logstash in apt
ElasticSearch provisioned on nodes
Nodes in Ganglia
LogStash package now in apt
Plan: start by piping in UDP log data at first, use that to inform crafting structured log directly from core

Module storage deployed everywhere
UDPProfiler patched to use hash table rather than BDB; resolves urgent perf issues
Triage: Perf issues in TimedMediaHandler tracked in bugzilla:58083; WikimediaShopLink in bugzilla:57939.
Starting to work on infrastructure for logging perf stats from core’s JS codebase: gerrit:99547
Going to set up a bits beacon URL for this data
