=== kgio 2.9.3 - minor cleanups and fixes / 2015-01-12 08:46 UTC

  Most notably there's a new RB_GC_GUARD to fix an occasional segfault at
  load time for Ruby 1.8 users thanks to Petr Novodvorskiy for reporting
  the issue.

  There's been a new mailing list for a few months now at:

      kgio-public@bogomips.org

  No subscription is required, but if you wish to subscribe
  (existing librelist subscribers must resubscribe)

      kgio-public+subscribe@bogomips.org

  There's also a bunch of code cleanups and packaging
  cleanups.  Our website is faster now thanks to olddoc:

=== kgio 2.9.2 - avoid deprecated/removed function / 2014-02-15 09:27 UTC

  This release is for compatibility with future releases of mainline ruby,
  as rb_thread_blocking_region is removed in r44955 of ruby trunk
  This also avoids deprecation warnings fo rb_thread_blocking_region
  2.0 and 2.1.

=== kgio 2.9.1 - various Ruby 1.8.7 fixes / 2014-02-05 17:50 UTC

  Thanks to Christopher Rigor for this release.

  Eric Wong (2):
        only define and test kgio_syssend on 1.9+
        various 1.8.7 fixes

=== kgio 2.9.0 - cleanups, bug fixes, minor improvements / 2014-02-04 03:09 UTC

  This adds a new kgio_syssend method for Ruby 1.9+ which behaves
  like BasicSocket#send, but will not raise exceptions on EAGAIN.

  Eric Wong (12):
        test_poll: remove race prone test_poll_EINTR_changed test
        tryopen: remove RARRAY_PTR usage in init

=== kgio 2.8.1 - minor improvements and test fixes / 2013-09-11 00:22 UTC

  Improved error reporting for kgio_accept/kgio_tryaccept.
  Minor size reduction throughout.  There are also several
  test case fixes for race conditions.

  Thanks to Hleb Valoshka and the Debian project for all the
  help with this release!

  Eric Wong (7):
        check syscall returns against < 0 instead of == -1
        accept: more informative exception on unknown family
        test_tryopen: skip EACCES test when euid == 0
        test/lib_read_write: account for larger-than-normal pipes
        test_poll: avoid potentially thread-unsafe test
        test_poll: preserve original trap(:USR1) handler
        test_poll: be less dependent on signal handler ordering

  Hleb Valoshka (4):
        Change prefix of temporary sockets to prevent races
        Don't dump 20M in case of failure
        Create own directory for every unix socket in unit tests

=== kgio 2.8.0 - TCP Fast Open, writev/trywritev / 2013-01-18 10:52 UTC

  TCP Fast Open in Linux 3.7 and later is now supported
  in the client via Kgio::Socket#kgio_fastopen.

  This release also adds the kgio_writev and
  kgio_trywritev methods, thanks to funny-falcon

=== kgio 2.7.4 - small fixes and cleanups / 2012-03-24 01:15 UTC

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

=== kgio 2.7.3 - compatibility fixes / 2012-03-15 07:11 UTC

  Fixed build and autopush support under Debian GNU/kFreeBSD.
  Test case fixes for timing-sensitive tests.

=== kgio 2.7.2 - for older, and older Rubies / 2012-01-08 03:42 UTC

  Fix a missing #include for Ruby 1.8.5 users.  No need to
  upgrade to this (nor 2.7.1) if you're on a modern version
  of Ruby.

=== kgio 2.7.1 - compatibility with older Rubies / 2012-01-08 01:59 UTC

  This release fixes some compatibility issues with people
  stuck on older versions of Ruby/RubyGems.

  * define RARRAY_PTR/RARRAY_LEN macros for Ruby 1.8.6
  * test/test_autopush: skip strace tests if not available
  * gemspec: disable development dependencies for old systems

=== 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
  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 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
