 * November 2013
 * August 2013

= Backlog/Wishlist =

We maintain a list of projects that would be great to have done, but are not on our roadmap in in the near term. See the wishlist here.

Feb - Apr '14 Goal Progress
See the WMF Engineering 13-14 goals page for the yearly view.


 * Process through all (useful) pain points from the Dev/Deploy review session (Greg)
 * Scap incremental improvements
 * 1) Refactor existing scap scripts to enhance maintainability and reveal hidden complexity of current solution (Bryan)
 * 2) create matrix of tool requirements per software stack (MW, Parsoid, ElasticSearch) (Greg)
 * 3) Use above matrix to add/fix functionality in scap (or related) tooling for ONE software stack, prioritized by cross stack use (Bryan)
 * Use the API to create test data for given tests at run time. (Jeff, Chris, Željko)
 * Create the ability to test headless (Željko, Jeff, Chris)
 * Run versions of tests compatible with target test environments (Chris, all)
 * Make database(s) in Beta Cluster emulate production (set up db slaves) (Antoine)

Greg

 * - Update/create new MW Release Management RFP


 * - Process through pain points
 * - security patches
 * - LD SWAT team
 * - config changes not being deployed after merge


 * - Refine deployment system requirements with Bryan
 * Deployment_tooling/Notes/Deployment_system_requirements

Bryan

 * Scap refactor/python port
 * Setup test environment in beta (carried forward from Feb & March; much harder than I'd hoped)
 * Continue to enhance and simplify scripts
 * Next generation deployment tooling
 * Organize requirements into wiki page (carried forward from Feb & March; pairing with Greg)
 * Support train deploys

Chris
Continuing from Feb:


 * Test and announce general availability of feature to check for ResourceLoader upon page load: ResourceLoader error checking more globally.


 * Test and announce general availability of feature to use the API to create wiki pages and users: create-page (and create-user) API.


 * Investigate how release branches are described in make-deploy-notes
 * Tracking this at https://bugzilla.wikimedia.org/show_bug.cgi?id=62509 . I have an idea about how to make this work.

Also:


 * Update documentation on mw.o to reflect the refactoring and consolidation of recent times. Much of what exists now is long out of date.
