posix_mq 2.0.0 - a minor API change + FreeBSD fixes
Blocking methods no longer raise Errno::EINTR (to match
Ruby IO semantics, making code easier to work with).
There are also many FreeBSD-related fixes thanks to
Hleb Valoshka <375gnu@gmail.com> and small code cleanups.

ext: fix type inconsistencies for int vs mqd_t retvals
Somehow I mixed up return values for mq_* functions that
return "int". This was noticed on FreeBSD where mqd_t
is NOT an integer.

blocking functions do not raise Errno::EINTR
Blocking functions should not raise Errno::EINTR to match
existing semantics of Ruby IO methods (e.g. IO.select, IO#read,
IO#write). This makes user code easier to read/write.
Like th Ruby methods we emulate, we only reacquire the GVL on
EINTR to fire signal handlers, but otherwise emulate SA_RESTART
semantics.
This is a backwards-incompatible API change (but unlikely
to break existing code).

posix_mq 1.0.0 - kinder, gentler message queues
There is one backwards-incompatible API change:
POSIX_MQ#send returns +true+ on success instead of +nil+
for consistency with POSIX_MQ#trysend.
This release adds the POSIX_MQ#trysend, POSIX_MQ#tryreceive and
POSIX_MQ#tryshift interfaces to avoid exceptions on common
EAGAIN errors for users of non-blocking queues.
Bugfixes: non-blocking behavior changes to a shared descriptor
in a different process are reflected immediately in the child
(this won't fix race conditions in your code, however).
Minor bugfixes for posix-mq-rb(1) and quieted warnings for
1.9.3dev.

posix_mq 0.7.0 - cleanups + portability fixes
This release now works for systems other than Linux and FreeBSD
that support POSIX message queues. This is usable for systems
without mq_timedsend() or mq_timedreceive() but with the
non-timed variants (timeouts wont work).
Thanks to Tadeusz Bochan for testing.
Ruby posix_mq is now dual-licensed under the GPLv2 (as well as the
preferred LGPLv3) for compatibility with existing GPLv2-only code.

While we're at it, use clock_gettime() instead of gettimeofday()
to avoid unnecessary timeval usage since mq_send/mq_receive
rely on higher-precision timespecs instead.

avoid double close() and EBADF
It can be dangerous to hit (and ignore) EBADF errors in
multi-threaded applications. Users of POSIX_MQ#to_io have two
Ruby objects pointing to the same file descriptor, making
things tricky when it comes time to reap resources.
We'll always prefer to close the Ruby IO object if it exists
(because we have less control over its GC behavior) and
ignore the raw descriptor.

posix_mq 0.5.0
Uncommonly raised exceptions due to programmer error are now
raised more safely with respect to the MRI garbage collector.
The "posix-mq.rb" executable has been renamed to "posix-mq-rb"
to respect RPS and is also hopefully easier to type/read when
used in scripts. I'm preserving the "rb" in the name since I
hope to have a more portable, C-only version someday.

rename `posix-mq.rb' executable to `posix-mq-rb'
".rb" in the executable name is discouraged by the
{Ruby packaging standard}[http://github.com/chneukirchen/rps]
and probably confusing.
If I ever get around to it, a non-Ruby version of this
executable is planned, and that will be called "posix-mq"

GC safety fixes
Avoid the RSTRING_PTR(rb_inspect(val)) construct, as it may not
preserve the value of rb_inspect() on the stack.

cleaner lookup "Signal" of constant
Instead of blindly defining a module, this is more flexible in
case Signal in Ruby itself becomes something other than a
module.

posix_mq 0.4.0
Small bugfixes and small API changes to avoid potential
issues/misuse are the focus of this release.
For non-blocking operation, the GVL is no longer bounced. This
reduces synchronization/scheduling overhead when used in
non-blocking applications.
Small cleanups and documentation improvements, too.
* make POSIX_MQ#dup and POSIX_MQ#clone no-op
* do not release GVL for non-blocking operations
* do not release GVL when unlinking/opening
* POSIX_MQ#<< does not release GVL when non-blocking
* avoid shadow warnings
* README: add mailing list archives info
* POSIX_MQ#to_io works under FreeBSD, too
* fix potential race with notify(&block)
* add TODO item for using netlink under Linux

ensure POSIX_MQ#name is clobber-proof
We don't want folks to accidentally clobber the value for
others, so allocate a new string object for it (don't worry,
rb_str_dup() is cheap in 1.9).

weird platform that we'd emit a warning for.

fix potential race with notify(&block)
We need to assign the notify_thread before assigning the
notification. Otherwise, there's a chance the notification
could fire and the notify_thread is not properly assigned for
the POSIX_MQ object when the pipe becomes readable.

do not release GVL when unlinking/opening
Since the message queue is not actually on a (slow) block
device, it's unlikely to block in a way where other tasks may be
scheduled by the kernel. So avoid complicating things and
unnecessary task switching and assume mq_open/mq_unlink can
be executed as fast as the CPU/memory subsystems allows.

do not release GVL for non-blocking operations
There's no point in wasting cycles releasing and reacquiring
a lock when we know we won't block. Since most non-blocking
users are expected to be single/few-threaded processes, this
will likely help them.

make POSIX_MQ#dup and POSIX_MQ#clone no-op
It'll cause problems for the automatic mq_close() during GC
otherwise, as dup(2) on an mqd_t isn't portable.
Of course there's no point in cloning or duping, either, as
mq_send/mq_receive operations are always atomic at the kernel
level and only one thread can have a notification registered
for it.

posix_mq 0.3.1
This fixes a misuse of the Ruby API leading to memory leaks in
cases where message queues are continually opened and closed
throughout the lifetime of the application.
Fortunately applications have little reason to repeatedly open
and close message queue descriptors: they are
multi-thread/multi-process-safe in every way imaginable and also
capable of non-blocking operation.

use GC correctly and avoid memory leaks
We still need to explicitly free the pointer we're given, and
not just close the associated file descriptor. Fortunately most
people to not spend all day opening/closing message queue
descriptors so this leak may not be noticeable.

posix_mq 0.3.0
This release adds a few new API methods, fixes MRI 1.8.6
support. We should now have full feature parity with
underlying POSIX message queue C API.
* POSIX_MQ#notify(&block)
RDoc: http://bogomips.org/ruby_posix_mq/POSIX_MQ.html#M000001
This is only supported on platforms that implement
SIGEV_THREAD with mq_notify(3) (tested with glibc + Linux).
Other platforms will have to continue to rely on signal
notifications via POSIX#notify=signal, or IO notifications
in FreeBSD (and Linux).
* POSIX_MQ#shift([buffer [,timeout]])
Shorthand for the common "POSIX_MQ#receive.first"
when you do not care for priority of the received message.
Rev, EventMachine and Reactor support are planned for
Linux, FreeBSD and possibly any other platforms where POSIX
message queues are implemented with a file descriptor.

there anyways...

no point in non-blocking for fd notifications
It's not needed since the native thread will retry in the
unlikely case of EINTR/EAGAIN. And writing one byte to a pipe
that's guaranteed by POSIX to be at least 512 bytes is highly
unlikely.
It's also bad because F_SETFL takes the big kernel lock under
Linux (and possibly other systems), and doing it unnecessarily
is a waste of system cycles.

without the priority.

POSIX_MQ#notify only works on GNU/Linux for now
SIGEV_THREAD is not easy to implement, so many platforms
do not implement it.

POSIX_MQ#notify block execution on message received
This is implementation uses both a short-lived POSIX thread and
a pre-spawned Ruby Thread in a manner that works properly under
both Ruby 1.8 (green threads) and 1.9 (where Ruby Threads are
POSIX threads).
The short-lived POSIX thread will write a single "\0" byte to
a pipe the Ruby Thread waits on. This operation is atomic
on all platforms. Once the Ruby Thread is woken up from the
pipe, it will execute th block given to it.
This dual-thread implementation is inspired by the way glibc
implements mq_notify(3) + SIGEV_THREAD under Linux where the
kernel itself cannot directly spawn POSIX threads.

mq_* functions besides mq_open(3) to be "int", not "mqd_t".

posix_mq 0.2.0
This release fixes notification (un)registration and should be
fully-supported on modern FreeBSD (7.2+) releases.
POSIX_MQ#notify=nil correctly unregister notification requests.
POSIX_MQ#notify=false now provids the no-op SIGEV_NONE
functionality. Under FreeBSD, using IO.select on POSIX_MQ
objects is now possible as it has always been under Linux.

Fix mq.notify = nil to unregister notifications
"mq.notify = false" also works now, doing what
"mq.notify = nil" used to do (using SIGEV_NONE).
I was confused by SIGEV_NONE usage vs using a NULL pointer for
the notification passed mq_notify(3). SIGEV_NONE does not
actually unregister, it registers a no-op notification which
prevents other processes from taking us.
This also fixes the test case to pass under both Linux and
FreeBSD.
