RubyForge: Rainbows!: File Release Notes and Changelog

Notes:
Release Name: 2.4.0

Notes:
kgio 2.4.0 - portability fixes and more

kgio provides non-blocking I/O methods for Ruby without raising
exceptions on EAGAIN and EINPROGRESS.  It is intended for use with the
Unicorn and Rainbows! Rack servers, but may be used by other
applications.

* http://bogomips.org/kgio/
* kgio@librelist.org
* git://bogomips.org/kgio.git

Changes:

== All supported platforms (*nix + MRI 1.8+, Rubinius)

* OpenBSD (and possibly other *BSD) fixes, thanks to Jeremy Evans.

* kgio_accept and kgio_tryaccept now take an optional second argument
  for flags (like the accept4() flags argument).

== Ruby 1.9-only things

* Kgio.poll no longer raises Errno::EINTR to match IO.select.

== Ruby 1.9 trunk things

* close() on an active FD in a different thread is better
  handled/detected.

* copy-on-write for strings is properly triggered

    test_cross_thread_close: disable on RUBY_ENGINE != "ruby"
    
    These aren't well-defined semantics...

    read_write: call rb_str_modify() before rb_str_resize()
    
    This is needed under Ruby trunk if the string is not actually
    resized.

    poll: deal with pollset changes on EINTR
    
    This allows callers to modify the pollset, interrupt
    the polling thread, and then poll with the modified
    pollset.  This is also important for dealing with
    closed IO objects that may have been invalidated
    due to GC, too.

    test_tcp_connect: disable wait_writable_set test on non-Linux
    
    OpenBSD seems to make connect() return success immediately even
    on a non-blocking socket, so it's hard to test for.
    
    Thanks to Jeremy Evans to reporting the issue under OpenBSD.

    connect: zero out hints argument for getaddrinfo
    
    Some systems like OpenBSD are stricter about irrelevant
    fields than GNU/Linux.

    *accept methods can take flags argument, like accept4()
    
    This allows applications to not rely on global accept4_flags
