=== kgio 2.7.0 - minor updates / 2011-12-13 06:16 UTC

  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.

=== kgio 2.6.0 - minor feature update and cleanups / 2011-07-15 02:01 UTC

  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.

=== kgio 2.5.0 - a minor feature update / 2011-06-20 19:30 UTC

  * Kgio::File.tryopen method added.  It is like File.open
    but won't raise exceptions.  The Kgio::File class includes
    Kgio::PipeMethods, so FIFOs opened through this get the
    kgio_* API.

  * The kgio_wait_*able methods in Kgio::DefaultWaiters
    now accept an optional timeout argument.

=== kgio 2.4.2 - OpenSolaris build fix / 2011-06-14 18:41 UTC

  * adds -lnsl and -lsocket checks for OpenSolaris

=== kgio 2.4.1 - Kgio.poll avoids EINTR, really / 2011-05-21 02:54 UTC

  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 2.4.0 - portability fixes and more / 2011-05-05 22:58 UTC

  == 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

=== kgio 2.3.3 - minor fixes / 2011-03-15 12:09 UTC

  We no longer over-allocate memory for Kgio.poll (1.9.x-only).
  Under Ruby 1.9.3dev, we also use rb_thread_io_blocking_region
  to properly deal with cross-thread IO#close.

=== kgio 2.3.2 - OpenBSD build fix / 2011-02-15 16:56 UTC

  Thanks to Jeremy Evans, this release fixes the build under OpenBSD.

=== kgio 2.3.1 - compatibility fix / 2011-02-14 00:51 UTC

  * connect.c: disable AI_NUMERICSERV

    It's not needed since we already verify the service is a
    numeric port.  AI_NUMERICSERV is not available in older glibc
    (<2.3.4) and probably other old systems.

=== kgio 2.3.0 - MSG_PEEK and poll(2) support / 2011-02-09 10:26 UTC

  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 / 2011-02-04 03:07 UTC

  * 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.

=== kgio 2.1.1 - one small Rubinius fix / 2010-12-26 02:08 UTC

  We now avoid errno side-effects in kgio_wait_*able methods.
  This affects Rubinius, but may affect other Ruby platforms
  (particularly those that use stdio) as well.

=== kgio 2.1.0 - accept improvements and fixes / 2010-12-26 01:07 UTC

  kgio_accept and kgio_tryaccept now take an optional argument
  to override the default Kgio::Socket class that is returned.

  These methods also fall back to using regular accept() if
  kgio was built on a system with accept4() and later run on
  a system without accept4().

=== kgio 2.0.0 - major internal API changes / 2010-11-19 01:18 UTC

  (no code changes from 2.0.0pre1)

  This release should make Kgio easier and more consistent
  to use across a variety of libraries/applications.

  The global Kgio.wait_*able(=) accessor methods are gone in favor
  of having default kgio_wait_readable and kgio_wait_writable
  methods added to all Kgio-using classes.  Sub-classes may (and
  are encouraged to) redefine these if needed.

  Eric Wong (7):
      expand Kgio::*#kgio_read! documentation
      prefer symbolic names for waiting read/writability
      EOFError message matches Ruby's
      README: Gemcutter => RubyGems.org
      update documentation with mailing list info
      add default kgio_wait_*able methods
      switch entirely to kgio_wait_*able methods

=== kgio 2.0.0pre1 - major internal API changes / 2010-11-18 23:16 UTC

  This release should make Kgio easier and more consistent
  to use across a variety of libraries/applications.

  The global Kgio.wait_*able(=) accessor methods are gone in favor
  of having default kgio_wait_readable and kgio_wait_writable
  methods added to all Kgio-using classes.  Sub-classes may (and

        update documentation with mailing list info
        add default kgio_wait_*able methods
        switch entirely to kgio_wait_*able methods

=== kgio 1.3.1 - fix zero-length reads / 2010-10-08 22:20 UTC

  kgio_read and kgio_tryread will now return an empty string when
  a length of zero is specified instead of nil (which would signal
  an EOF).  This emulates the behavior of IO#read, IO#readpartial,
  IO#sysread, IO#read_nonblock in core Ruby for consistency.

=== kgio 1.3.0 - bug and usability fixes / 2010-10-08 03:03 UTC

  * make Kgio::WaitWritable and Kgio::WaitReadable symbols
  * trywrite: fix stupid off-by-one error causing corrupt writes
    on retries

=== kgio 1.2.1 - doc and *BSD workarounds / 2010-10-07 07:20 UTC

  This fixes our accept4() wrapper which did not work as expected
  on some *BSD-based systems due to fcntl(fd, F_GETFL) returning
  false information.  Linux 2.6+ users are unnaffected, including
  those without accept4().

  Also some RDoc fixes.

=== kgio 1.2.0 - cleanups and minor improvements / 2010-10-05 23:14 UTC

  The C extension is now split into several files for
  ease-of-maintenance.

  Slightly more common, client-triggerable exceptions (EOFError,
  Errno::EPIPE, Errno::ECONNRESET) are now less expensive as they
  are generated without backtraces.

=== kgio 1.1.0 - flexible accept methods / 2010-09-29 01:17 UTC

  * alternate classes may now be returned by accept/tryaccept
    by setting Kgio.accept_class=

=== kgio 1.0.1 - compatibility fixes / 2010-09-28 03:00 UTC

  * add compatibility for ancient Rubies (1.8.6)
  * linux: fix accept4() support for newer Linux

=== kgio 1.0.0 - initial release / 2010-09-28 00:29 UTC

  A kinder, gentler I/O library for Ruby
