Funded items

The goals of the hackathon are:

  • to get people working with ZFS engineers from outside their normal circles
  • to start work on some of the projects we'd like to accomplish

Therefore, we should plan to work in small teams of 2-3 engineers. The team members could be pair-programming, splitting up the work into discrete tasks for each person, or advising / implementing.

Hackathon ideas

Add your idea and your name below. Be prepared to explain your idea at the beginning of the hackathon and enlist/entice others to help with it.

  • Channel Programs - continuation of work from last year's hackathon
  • "get next file" syscall
    • iterates in object # order, opening next file; zfs prefetches dnodes
    • could speed up operations that need to operate on every file in a filesystem, e.g. "chmod -r"
  • Porting Party - learn how to contribute changes to a new platform
