Ideas for OpenStack Swift

This is a list of stuff you might be interested in working on. Most of these are smaller, self-contained projects that probably won't overlap too much with other ongoing work. This is a great place to get some ideas of things to work on.

• use keystone api in swift client, if possible
• change default ports - https://review.openstack.org/#/c/118200/
• reverse listings - https://review.openstack.org/#/c/120709/
• stdin streaming to swiftclient
• ring validator (in swift-recon): eg test that something is running on the ports in the ring -- not just "something", must verify correct type, because deployers sometimes flip a/c/o and then inexplicable 400 happens -- https://wiki.openstack.org/wiki/OutreachProgramForWomen/Ideas#Swift_-_storage_server_OPTIONS_support_and_checker_tool
• deep health check to test all the way to drives (? or at least storage servers)
• better ring deployment inside of swift itself
• need internal net sec enforcement - https://blueprints.launchpad.net/swift/+spec/secure-internal-network-requests
• change the ssync (object-replicator) design to be run as another process for concurrency
• durability simulator based on swift specification (e.g. # of replicas, # of devices and network speed to replicate) (inprogress by Christian)
• in the situation where a proxy needs to talk to a storage node on the same server, call the storage node method(s) directly instead of putting bytes on the network (somewhat in progress)
• skeleton middleware, well-commented
• fsync directories (talk to portante or notmyname in IRC about this) - https://review.openstack.org/#/c/126923/
• DiskFile entry point
• policy descriptions, exactly how https://review.openstack.org/#/c/120424/ is not implemented (see the review comments)
• allow multiple storage policy names for one policy
• rewrite server-side-copy (COPY and PUT with x-copy-from) as middleware
• utility to "undelete" accounts, as described in http://docs.openstack.org/developer/swift/overview_reaper.html
• add account-to-account server-side copy docs. actually just add server-side copy docs
• Exposed allowed and denied headers on tempurl requests in /info. See http://docs.openstack.org/developer/swift/middleware.html#tempurl
• expose container sync enablement in /info
• expose versioned writes enablement in /info
• API endpoint for invalidating cached auth tokens
