When interfacing with APIs that expect unix-style async I/O, it is
useful to be able to tell in advance whether a read/write is going to
block. This adds new interfaces GPollableInputStream and
GPollableOutputStream that can be implemented by a GInputStream or
GOutputStream to add _is_readable/_is_writable, _create_source, and
_read_nonblocking/_write_nonblocking methods.
Also, implement for GUnixInput/OutputStream and
GSocketInput/OutputStream
https://bugzilla.gnome.org/show_bug.cgi?id=634241
Otherwise, attempting to create a GSocketConnection from the socket
will likely return the wrong type, since the protocol won't match any
of the registered subtypes.
Also add the start of a GSocket test program (from davidz).

The root problem is with GObject - for now, just work around it in
GDBus. Also include a test-case. See
https://bugzilla.gnome.org/show_bug.cgi?id=627724

Don't actually use this yet as that will require a couple of
modifications to the filter function signature. This is part of the

Add a <flags> tag to the schema file format and a flags='' attribute to
go along with. Add some extra test cases for those.
Add new g_settings_{get,set}_flags() calls and support binding to
GParamSpecFlags properties. Add test cases.
Add support for extends='' and list-of='' tags to the <schema> element.
The attributes are parsed and some sanity-checking is done but currently
nothing happens as a result.
Add some tests.
Allow constructing a GDBusProxy for well-known names as discussed here
http://mail.gnome.org/archives/gtk-devel-list/2009-October/msg00075.html
including test cases.
Make it possible to create a GDBusProxy for a GBusType instead of a
GDBusConnection. This requires G_BUS_TYPE_NONE so add that too.
Nuke g_bus_watch_proxy() since one can now more or less use GDBusProxy
for this.
Port gdbus-example-watch-proxy to this new API and include this
example in the GDBusProxy doc page.
Also nuke the GType parameter from the GDBusProxy constructors as
requested here: https://bugzilla.gnome.org/show_bug.cgi?id=621229
Also update the porting guide and other API docs for this change.
Also fix a bug in the signal dispatching code so each subscriber only
get notified once, not N times, for the same signal. Also add a test
case for this.

This adds a GApplication object to GIO, which is the core of
an application support class, supporting
- uniqueness
- exporting actions (simple scripting)
- standard actions (quit, activate)
The implementation for Linux uses D-Bus, takes a name on the
session bus, and exports a org.gtk.Application interface.
Implementations for Win32 and OS X are still missing.
- Fix various #include issues
- Change #error to #warning for the EXTERNAL authentication mechanism.
It is not clear if this should work on Win32 at all.
- Call close() before unlink() for the SHA1 keyring
- Change #error to #warning so we don't forget to do
permission checking of the .dbus-keyrings directory
- Use Win32 SID for the SHA1 auth mech
- Apparently we can't use word 'interface' as an identifier
- Implement a _g_dbus_win32_get_user_sid() function. For now it's
private. Don't know if it should be public somewhere. Maybe in
a future GCredentials support for Win32? I don't know.
- GFileDescriptorBased is not available on Win32. So avoid using
it in GLocalFile stuff. Now, Win32 still uses GLocalFile + friends
(which works with file descriptors) so expose a private function
to get the fd for an OutputStream so things still work.
- Fixup gio.symbols
- Fixup tests/gdbus-peer.c so it builds
With this, at least things compile and the gdbus-peer.exe test case
passes. Which is a great start. I've tested this by cross-compiling on
a x86_64 Fedora 13 host using mingw32 and running the code on a 32-bit
Windows 7 box.

Things compile and the test-suite passes. Still need to hook up
gio.symbols and docs. There are still a bunch of TODOs left in the
sources that needs to be addressed.

There are apparently two incompatible ways of naming abstract sockets:
pad the sockaddr with 0s and use the entire thing as the name, or else
don't, and just pass a shorter length value to the relevant functions.
We previously only supported the former method. Add support for the
latter.
Also correctly handle "anonymous" unix sockaddrs (eg, the client side
of a connection, or a socketpair() socket), and add unix domain socket
support to the socket-client and socket-server test programs to make
sure this all works.

Gschema-compile uses glob which is available on Unix only. Thus can't
run the gschema-compile test except on Unix either.
To avoid an Automake error, comment out the SOURCES and LDADD of
unix-streams which for some reason has been commented out from
TEST_PROGS.
Can't use a Makefile.am target called foo_PROGRAMS for random files
that aren't actually programs, as Automake assumes EXEEXT should be
appended to the file names.
Correspond to GUnixInputStream and GUnixOutputStream. No true async
support though. But that is how the Win32 API is, for files not
explicitly opened for so-called overlapped IO.
The API to create these streams takes Win32 HANDLEs. Not file
descriptors, because file descriptors are specific to the C library
used. The user code and GLib might be using different C libraries.
Also add a test program for the new classes, and a gio-windows-2.0.pc
file.
It turns out that the way this worked did not work out for the current
main usecase (gedit) due to issues with how this is best integrated
with GtkTextView. So, in order to not have to support an unused non-ideal
API forever we remove this before its been in a stable release.
The basic feature seems to have some utility though, so we hope for it
to eventually return in a better form.
GFile allows for the possibility that external implementations may not
support thread-default contexts yet, via
g_file_supports_thread_contexts(). GVolumeMonitor is not yet
thread-default-context aware.
Add a test program to verify that basic gio async ops work correctly
in non-default contexts.

In particular, targets with weight 0 should be very UNlikely to be
selected, not very likely, as they were before. However, even ignoring
that bug in the logic, there was an additional bug (swapping list
items would cause the 0-weight items to get re-ordered incorrectly
anyway), and the code contained several fencepost errors.
This patch also adds gio/tests/srvtarget.c, which confirms that for a
sample list of targets, we now generate all possible correct random
sortings and no incorrect sortings, and the correct sortings occur in
roughly the expected proportions (though if the current code is
still wrong, those proportions may be wrong as well).

GResolver provides asynchronous (and synchronous-but-cancellable) APIs
for resolving hostnames, reverse-resolving IP addresses back to
hostnames, and resolving SRV records. Part of #548466.
