Most notably, this fixes memory leaks for any users of inotify reads, epoll/kevent waiting using short-lived thread. Users of long-lived threads for these functions (all Rainbows!, yahns, and zbatery users) are not affected. A fair amount of internal cleanup was necessary for this. Compatibility with non-Linux systems without clock_gettime is improved, thanks to Lin Jen-Shin. Note: the kevent code is not at all optimized and still uses RARRAY_PTR, so it likely sucks under rbx and MRI 2.1.

epoll support and thread-safety improvements. The dangerous Epoll::IO interface is now an option for those who want to share an epoll descriptor across fork and maintain their own IO object references to avoid extra overhead. Use the regular (high-level) Epoll interface unless you're willing to shoot yourself in the face. There is also preliminary Kqueue support (which should work under libkqueue on Linux). Similar to our epoll interface (and unlike most event libraries/frameworks) our kqueue interface also supports one-shot notifications and _embraces_ multi-threaded use. Note: unlike epoll, kqueue has close-on-fork behavior, so kqueue descriptors are not (ever) inheritable across fork. Added EPOLLWAKEUP constant (Linux 3.5 + glibc 2.17 required) to allow descriptors to prevent system suspend while active (this requires the CAP_BLOCK_SUSPEND privilege). Inotify and Epoll interfaces now use thread-local buffers for thread-safety and improved concurrency without GVL. Errno::EINTR is no longer propagated into Ruby-land, for consistency with existing Ruby IO APIs.
* add TimerFD::CANCEL_ON_SET constant ref: http://www.man7.org/tlpi/api_changes/ * fix concurrent Epoll#wait on the same epoll fd * SignalFD interface removed (unworkable with Ruby runtimes) * use rb_update_max_fd() if available (Ruby 1.9.3) * reintroduce SLEEPY_PENGUIN_VERSION constant ("3.1.0")
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.
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).
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.
* Epoll#wait: do not automatically retry on EINTR * preliminary Inotify support * Epoll.new no longer defaults to close-on-exec TODO: FANotify + SignalFD
One bugfix for Epoll#delete: Eric Wong (1): safer closed checks for proxied objects
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.
