Search

Deploy Tooling

 * (ori on plane) scap to python : https://gerrit.wikimedia.org/r/110904
 * Bryan’s notes on scap: https://www.mediawiki.org/wiki/Deployment_Tooling/What_does_scap_do
 * Script should have a link to that wiki page :-D Tip: we can later use sphinx to generate documentation for the scap script.
 * fatalmonitor as logstash dashboard: https://logstash.wikimedia.org/index.html#/dashboard/elasticsearch/fatalmonitor
 * Needs a LDAP account in the wmf group (can be asked via RT/Chad).

Performance

 * (Tim) Began design work for HHVM Lua extension
 * (Aaron) ActiveUsers rewrite (pre-computed results)
 * (Aaron) AbuseFilter throttler DB query tweak (hopefully should avoid incidents like the last one on enwiki)
 * (Aaron) Job queue and parser cache usage tweaks
