kgio 2.8.0 - TCP Fast Open, writev/trywritev
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

rename fastopen => kgio_fastopen in Kgio::Socket
In the unlikely case the Ruby Socket class implements its
own "fastopen" method, we will avoid conflicting.

accept: do not set blocking if non-blocking is set
This is prone to race conditions in multiprocess situations
where one process is relying on non-blocking operation while
another (likely newer process) relies on blocking operation.
Since the blocking process can always fall back to calling
rb_io_wait_readable(), use that instead and give up some
scalability for higher reliability.
Those interested in avoiding thundering herds will have to
stop/start their processes using blocking sockets (and tolerate
some downtime).

read_write: remove unused variable
commit f61cef65b8a8816160c622324b4f1aad55034e4a
Author: Eric Wong <normalperson@yhbt.net>
Date: Thu Dec 27 01:16:56 2012 +0000
implement TCP Fast Open support (client + server)
Server support just requires exposing one constant for
setsockopt: Kgio::TCP_FASTOPEN
Client support implements a new Kgio::Socket#fastopen method.
This new method wraps the the sendto() syscall. With TCP Fast
Open, the sendto() syscall is overloaded for stream sockets to
implement the functionality of both connect() + write()
Since it only makes sense to use _blocking_ I/O for sendto(),
TFO clients are only supported in Ruby implementations with
native threads.

Kgio::Socket.new retains compatibility with Socket.new
This allows us to create an unconnected socket, just like
the normal Socket class it inherits from.

tryopen: include errno.h header just in case
errno.h is not guaranteed to be included in existing headers,
so we need to #include it to ensure errno and friends are
usable.

test workaround for platforms with unreliable signals
Ruby may not respond well to signals on all platforms, especially not
after fork()-ing in the face of a running pthread (timer thread on
1.9.2). SIGKILL bypasses Ruby (and all userspace) signal handling on
Debian GNU/kFreeBSD.

test/lib_read_write: wait for readability before tryread

commit ff27e74a49bf6746ffe74cfc865430221f0bafe0
Author: Sokolov Yura 'funny-falcon <funny.falcon@gmail.com>
Date: Fri Jun 1 13:42:58 2012 +0400
add `#kgio_writev` and `#kgio_trywritev`
Add methods for using writev(2) syscall for sending array of string in
a single syscall. This is more efficient than concatenating strings on
Ruby side or sending them one by one.
`#kgio_trywritev` returns array of strings which are not sent to the
socket. If there were objects other than string, they could be converted
using `#to_s` method, but this is not strictly applied, cause
`#kgio_*writev` tries to write at most `sysconf(_SC_IOV_MAX)` items
at once (for Linux its value is 1024). First string of returned array
could be part of string from array, so that you should assume it is not
in consistent state.
`#kgio_writev` semantic differs a bit from `#kgio_write` in term of
buffers mutability: currently `#kgio_write` tries to follow string changes
made concurrently, but `#kgio_writev` works with array's lightweight copy.

use rb_str_subseq for tail string on write
Use rb_str_subseq for taking string's tail. rb_str_subseq do not allocate
additional memory in this case. And although it prevents from collecting
original string, it seems that tests wins both in performance and in memory
usage.
Use fallback to rb_str_substr on ruby1.8

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.

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.

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.

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.

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.

This release fixes a race condition that could allow

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

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.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 2.2.0 - 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.

avoid initiating syscalls before rb_io_wait_*
Some Ruby implementations (Rubinius) may call lseek
and clobber the intended errno when looking up the
open file, causing rb_io_wait_* functions to fail.

add kgio_tryaccept, kgio_accept _really_ blocks
We'll stick with the "try" prefix if we're going to be
non-blocking. kgio_accept will favor a blocking accept() call
where it's possible to release the GVL, allowing it to avoid
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.
