  • File src/OFKernelEventObserver_select.m — part of check-in [c5f0c5f9ba] at 2015-12-29 21:42:38 on branch 0.8 — Refactor OFKernelEventObserver

    This moves the locked queue for actions to
    OFKernelEventObserver_LockedQueue, which is now used for select and
    poll, but skipped for kqueue and epoll, as they natively support changes
    from another thread.

    This fixes the problem that removing an object is delayed until the next
    observe call - at which point it might have already been closed, meaning
    the fd is no longer available. This was mainly a problem with kqueue, as
    closing the fd already removed it from the kqueue, which then resulted
    in an error being returned when trying to manually remove the fd from
    the kqueue. (user: js, size: 4761) [annotate] [blame] [check-ins using]
