* 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.
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.
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)
