=== sleepy_penguin 3.0.1 - really avoids EINTR / 2011-05-21 02:40 UTC

  One bugfix:

  * epoll: avoid race condition in EINTR checking

    Even if we timeout while getting an EINTR, we'll retry
    epoll_wait() with a zero timeout like IO.select does in Ruby to
    avoid raising Errno::EINTR.

=== sleepy_penguin 3.0.0 / 2011-05-21 00:22 UTC

  Epoll#wait always waits the specified amount of time and never
  raises Errno::EINTR.

  Disabled operations on Fixnum file descriptors, only IO objects
  may be passed to Epoll methods.

  Cross-thread Epoll#close behavior matches Ruby 1.9.3dev.

  Improved Rubinius support (lightly tested).

=== sleepy_penguin 2.0.0 / 2011-03-10 04:43 UTC

  There are many internal cleanups, bugfixes, and incompatible
  API changes.  The API will probably be stable from now on.

  All the flag passing is less verbose, in the past you had
  to do:

      tfd = TimerFD.new(TimerFD::CLOEXEC|TimerFD::NONBLOCK)

  Now, you can just do (the old way still works):

      tfd = TimerFD.new([:CLOEXEC, :NONBLOCK])

  A SignalFD interface now exists, but is not recommended since
  MRI signal handling seems to conflict with it.

  Inotify#close no longer holds the GVL while closing the
  descriptor since it is an expensive operation.

  See git log v1.4.0..v2.0.0 for all the gory details.

=== sleepy_penguin 1.4.0 - Linux I/O events for Ruby / 2011-02-04 22:27 UTC

  * Epoll#wait: do not automatically retry on EINTR
  * preliminary Inotify support
  * Epoll.new no longer defaults to close-on-exec

  TODO: FANotify + SignalFD

=== sleepy_penguin 1.3.1 - safety checks for delete / 2011-01-22 00:52 UTC

  One bugfix for Epoll#delete:

  Eric Wong (1):
        safer closed checks for proxied objects

=== sleepy_penguin 1.3.0 - incremental improvements / 2011-01-21 23:12 UTC

  This release introduces compatibility with pre-EPOLLRDHUP
  systems.

  It also optimizes syscalls away for Epoll#set and Epoll#delete.
  Epoll#add, Epoll#mod and Epoll#del should no longer be needed in
  most code.

=== sleepy_penguin 1.2.0 - epoll GC help / 2011-01-15 12:06 UTC

  One convenience fix:

    epoll: prevent IO objects from getting GC-ed

    Users of our code may forget to keep references for their IO
    objects at all, and since it's not possible for GC to mark
    kernel memory, we just hold on to the IO objects for them.

    We can't unmark close()d file descriptors, ever, so we don't
    bother with the EPOLL_CTL_DEL case, either.  Just storing IO
    objects in an array using the raw descriptor as a key will allow
    bounded space usage just like the in-kernel FD tables as long
    as the user remembers to close descriptors themselves.

=== sleepy_penguin 1.1.1 - soft feathers, soft delete / 2011-01-13 22:41 UTC

  SleepyPenguin::Epoll#delete method added for "soft" failures
  Documentation updates and cleanups, the website is now
  JavaScript-free!

  (Ignore the 1.1.0 "release", it was a lie)

=== sleepy_penguin 1.0.0 / 2010-09-26 06:31 UTC
