    kgio 2.7.4 - small fixes and cleanups

    Fix build for platforms lacking both TCP_CORK _and_ TCP_NOPUSH
    There are many test case fixes and cleanups, too.

    test/lib_read_write: test workarounds for TCP in FreeBSD 9.0

    Under load, TCP sockets may not register as readable right away
    after the writer finishes.  This can be expected for
    implementations where loopback TCP is a closer simulation of
    non-local TCP traffic.

    These test failures were noticed under FreeBSD 9.0.

    test_tryopen: fix horribly-named test for EACCES

    We can't actually test for EPERM without changing
    permissions/ownership, and we can't do that without root...

    test/lib_read_write: increase test reliability

    IO#readpartial may not drain the socket buffers enough for
    kgio_write to succeed on some platforms.  So use IO#read for
    read-in-full behavior.

    test/*: remove assert_nothing_raised

    It makes test failures hard to track down, tests will
    already fail if exceptions are thrown and we'll get
    nice backtraces.

    fix for non-Linux, non-TCP_NOPUSH platforms

    We don't need to care for TCP_NOPUSH in read_write.c, it's
    entirely in autopush.c and no-op on platforms without
    TCP_CORK/TCP_NOPUSH.  TCP_CORK/TCP_NOPUSH are non-POSIX, so
    it's entirely possible some Free systems will lack them.

    It seems autopush support in our autopush code has
    always been broken outside of Linux-based systems,
    as we never marked the socket as having pending data.

    kgio 2.7.0 - minor updates

    When running under Ruby trunk/2.0.0dev, all IO objects created
    by kgio will be close-on-exec by default to match the (future)
    2.0.0 behavior.  accept()ed sockets in kgio have always been
    close-on-exec by default..

    Singleton Kgio.accept_* methods are deprecated as the
    kgio_accept/kgio_tryaccept methods all take an additional
    flags argument.

    There are various, test, documentation, and error message
    improvements.

    doc: update documentation regarding accept method flags

    There's no reason for SOCK_NONBLOCK with Ruby, and SOCK_CLOEXEC
    has always been on-by-default with accept() wrappers.

    connect,tryopen: set close-on-exec flag for new fds on Ruby 2.0+

    All IO objects created by Kgio will have FD_CLOEXEC descriptor
    flag set on it when run under Ruby 2.0.0dev.  This matches the
    upcoming behavior of Ruby 2.0.0dev for IO objects in the core
    and standard library.  This change does not affect users on Ruby
    1.9.3 and earlier.

    accept()-ed sockets in kgio have _always_ had FD_CLOEXEC
    set by default.

    tests: remove tests for IO#nonblock? after accept

    There's no point in testing a Ruby implementation detail and
    these tests fail under OpenBSD where the accept()-ed socket
    inherits the O_NONBLOCK flag from the parent.

Author: Eric Wong <normalperson@yhbt.net>
Date:   Tue Nov 15 13:20:25 2011 -0800

    accept: deprecate singleton Kgio.accept_* methods

    The kgio_accept and kgio_tryaccept methods now take an
    additional flags argument, so there's no reason to set
    global flags anywhere.

Date:   Tue Nov 15 13:18:32 2011 -0800

    accept: always set O_NONBLOCK for accept()-ed sockets in 1.8

    This is mostly an implementation detail, but it's already
    true on OpenBSD (and maybe other BSDs), and also requires
    no additional syscalls on newer Linux systems.

    kgio 2.6.0 - minor feature update and cleanups

    We now export SOCK_NONBLOCK, SOCK_CLOEXEC constants in the Kgio
    namespace to make kgio_tryaccept/kgio_accept easier-to-use.
    There are also some minor internal cleanups.

    add prototype for rb_thread_blocking_io_region()

    It's no in the public headers, but Ruby 1.9.3 will have it and
    it's still superior to rb_thread_blocking_region() even though
    it's not ideal.

    export SOCK_NONBLOCK, SOCK_CLOEXEC constants in Kgio

    It's more reliable than relying on IO::NONBLOCK and
    Fcntl::FD_CLOEXEC constants.  The existing constants are not
    guaranteed to be equivalent to what accept4() takes even
    though the current Linux implementation does it this way.

    make timed kgio_wait_* implementation safer

    IO.select can handle fd >= 1024 safely in some Rubies while
    fd_set may not.  We could use rb_thread_fd_select(), but
    rb_wait_for_single_fd() is available now so the former
    is not worth the maintenance hassle.

    add timeout to kgio_wait_{read,writ}able

    io/wait doesn't have an IO#wait_writable method, yet[1]
    and IO#wait checks FIONREAD which makes it unsuitable
    for certain descriptors.

    This method uses the new rb_wait_for_single_fd() function in
    Ruby 1.9.r.  This internally uses ppoll() under Linux, meaning
    it performs the same regardless of the FD used.

      Kgio.poll: ensure EINTR never gets raised

    kgio 2.4.1 - Kgio.poll avoids EINTR, really

    This release fixes a race condition that could allow
    Errno::EINTR to be raised even though the 2.4.0 release
    was supposed to stop that.

    Nobody uses Kgio.poll, really, so this shouldn't be an issue
    for real code, yet.

    Kgio.poll: ensure EINTR never gets raised

    Retry on a zero timeout if we get interrupted
    even if the timeout expired.  This is also what
    IO.select does in Ruby itself.

    Kgio.tryopen => Kgio::File.tryopen

    This will allow users to subclass Kgio::File and
    override certain behavior (e.g. overriding "#each").

    return Kgio::File for Kgio.tryopen

    This also allows us to return/override #to_path and #path if
    necessary, but so far everything works with MRI 1.8, MRI 1.9,
    and Rubinius.

    add Kgio.tryopen method

    For the case where a file is readable, it's faster to
    just call open() instead of stat()-ing and then calling
    open().

    open() failures are still relatively cheap, too, they're still
    more expensive than a failed stat() but cheaper than raising
    an exception.

    kgio 2.4.0 - portability fixes and more

    == 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

    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.

    kgio 2.3.0 - MSG_PEEK and poll(2) support

    recv() with MSG_PEEK for sockets is added with the try*
    interface.  SocketMethods#kgio_trypeek and
    SocketMethods#kgio_peek or Kgio.trypeek for non-Kgio-enabled
    sockets.

    For Ruby 1.9 only: poll(2) is exposed via the Kgio.poll
    singleton method and should provide an alternative for IO.select
    users.

    Both of these new features should work well on modern Unix-like
    operating systems.

    kgio 2.2.0 - kinder, gentler I/O for the Internets

    * sockets accept()ed by a TCP_NOPUSH/TCP_CORK listener
      automatically flush on kgio_*read calls if there is pending
      data.  "Kgio.autopush = false" disables this globally,
      and Kgio::Socket also get "kgio_autopush=" to enable/disable
      on a per-object individual basis.

    * ECONNRESET exceptions get empty backtraces for kgio_*read.
      There's nothing a programmer can do about these, so there's
      no point in going through the expensive backtrace generation
      process.

    * Kgio.try* singleton methods added for working with non-Kgio
      enhanced objects.  No more needing to use Object#extend
      and blowing away your method cache to make existing I/O
      objects kinder and gentler.

    * IPv6 support should be complete, systems without a native
      getaddrinfo(3) are now unsupported (and will remain so
      unless somebody complains).

    There should be no other backwards-incompatible changes other
    than requiring getaddrinfo(3) and friends for IPv6 support.

    autopush: optimize away ivar usage under MRI

    We know that all versions of MRI have a small RFile structure
    that is allocated in the same object slots as other Ruby types
    and also zeroed on allocation.

    This optimization enables us to fall back to using ivars in
    case MRI changes or if we're used on other Rubies.

    preliminary implementation of "smart_nopush"

    It only supports TCP_CORK under Linux right now.

    We use a very basic strategy to use TCP_CORK semantics optimally
    in most TCP servers:  On corked sockets, we will uncork on recv()
    if there was a previous send().  Otherwise we do not fiddle
    with TCP_CORK at all.

    Under Linux, we can rely on TCP_CORK being inherited in an
    accept()-ed client socket so we can avoid syscalls for each
    accept()-ed client if we already know the accept() socket corks.

    This module does NOTHING for client TCP sockets, we only deal
    with accept()-ed sockets right now.

    Make kgio_trywrite more aggressive with retrying

    Partial writes can be retried until completely denied with
    EAGAIN.  Often times, it is beneficial to retry immediately
    after a partial write because the kernel may allocate more
    buffers or the reader can drain the buffers.

    This helps the caller avoid crossing the Ruby <-> C boundary
    more than necessary.

    thundering herd problems.  Otherwise it'll use thread-safe
    blocking under Ruby 1.8.

    use SOCK_NONBLOCK for socket(2) if possible

    This saves us a relatively expensive fcntl() system call.

    connect: no do not leak descriptors on failure

    We cannot raise exceptions and expect GC to clean up
    after us until we've created an actual IO object.

    "start" singleton methods for non-blocking connect

    These initiate (but do not wait for) non-blocking connects.

    introduce kgio_try* methods

    Avoid altering behavior based on globals that
    Kgio.wait_{read,writ}able stored in, since that's too confusing.
    The non-try variants are closer to the normal IO read/write
    methods, except they can be more easily plugged into alternate
    reactors and event frameworks.

    kgio_read returns nil on EOF

    Just like IO#read

    split out reusable bits into separate headers

    No point in cluttering up the meat of our code.

    only use MSG_DONTWAIT under Linux

    MSG_DONTWAIT is less consistently implemented/supported on other
    platforms on stream sockets, so fallback to fcntl() + read()/write()
    for stream sockets.  This also fixes our previously broken support
    of non-MSG_DONTWAIT systems.

    beef up the test suite

    We need to test server <-> client interaction
    more thoroughly since some systems don't implement
    everything right.
