Like how we're handling activation, use GVariant for timestamps. To
avoid polluting the GtkApplication API with GVariants, we rename the
GApplication signals to "quit-with-data" and "action-with-data".
GtkApplication will then wrap those as just "quit" and "action".

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.

The name buffer_availabile was kinda confusing, so its been renamed
to buffer_data_size() to match buffer_data().
Also I added a comment to buffer_ensure_space because its behaviour
wasn't obvious.
When the converter fills the whole buffer without reading all input,
we need to enlarge the buffer. Otherwise we get an assertion failure
for `outbuf_size > 0' in g_converter_convert.

gvdb just dropped the ability to have a separate "options" field. We
now store the options into a GVariant along with the default value.
For now, we use a small shim in GSettingsSchema in order not to touch
too much code. A more complete rewrite will follow.
This represents a change to the schema file format with another likely

Create a function run_with_application that both ensures the
app is running exactly while the test is running, which most
of the tests use. We start it beforehand, and kill it after.
This avoids having any interdependence between the tests (and
there definitely was before, because we didn't wait for
the process to actually terminate after a kill() call).
Also, open a pipe between the two, and have the child app
monitor that pipe. If it gets closed (e.g. because the parent
died), the child exits. This is the most reliable way to
avoid stale children; before, if we failed an assertion, the
parent would abort, and not run kill().

Fix proxy construction for objects with no properties in the case
where G_DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES isn't set.
The unfortunate side-effect here is that GDBusProxy can no longer be
used to test for "object existence", e.g. creating a GDBusProxy for
any path and interface will not fail. But that's not really a big
deal, if apps rely on that they are doing something very wrong.

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.
The GSettings schema compiler was accepting any string as a path. It is
probably quite a common mistake to suspect that '/apps/foo' is a valid
path name when this will cause all sorts of trouble later. Check for
this case and report the error.
Since #include <gsettingsbackend.h> is a perfectly valid thing for
applications to do, and since we want to include gio headers from
gsettingsbackend.h, we need to effectively disable the #error we would
get from those headers (because we're not coming via gio.h).
We don't want to #include <gio/gio.h> here because this would cause
needless rebuilding of GSettingsBackend, GSettings,
GDelayedSettingsBackend, etc... every time someone changed anything in
any public header.
add GSimplePermission, a trivial const implementation of GPermission
can-request and can-release are always false for this implementation and
the value of 'allowed' is decided at construction.
Add GObject introspection annotations so that the length parameter is
correctly detected for g_variant_new_strv(), g_variant_get_strv() and
g_variant_dup_strv(). Also specify that it can be a NULL pointer in
g_variant_get_strv() and g_variant_dup_strv().
For g_settings_set_strv(), detect that a NULL value is allowed, meaning
empty array.

Length of the array is redundant since it's NULL-terminated. This is not
consistent with many GLib and GTK+ functions, and adds complexity with
no real gain, while these convenience functions should be kept simple.
Closes bug #620312
This allows the caller to specify the reply type that they are expecting
for this call. If the reply comes back with the wrong type, GDBus will
generate an appropriate error internally.
- add a GVariantType * argument to g_dbus_connection_call() and
_call_sync().
- move the internal API for computing message types from introspection
data to be based on GVariantType instead of strings. Update users
of this code.
- have GDBusProxy pass this calculated GVariantType into
g_dbus_connection_call(). Remove the checks done in GDBusProxy.
- Update other users of the code (test cases, gdbus-tool, GSettings
tool, etc). In some cases, remove redundant checks; in some other
cases, we are fixing bugs because no checking was done where it
should have been.
Closes bug #619391.
Ryan pointed out on IRC that we didn't do anything here. Looking at

If --uninstall is given then don't give an error if the schema directory
is empty. Instead, erase the gschemas.compiled file, if it exists.
This is the right thing to do in the 'make uninstall' rule, where the
schema directory could very well be left empty as a result.
Modify gsettings.m4 to use this option.
The test was assuming that g_timeout_add() waited for at least the amount of
time given to it before running the function. This is not the case -- the
function can be run as much as 1ms early. Make the lower time bound asserted
in the test more permissive to account for this.
- hold a lock while accessing the tree of delayed values
- use weak reference counts with the owner object to avoid doing
g_object_notify on a dead object
- dispatch the "has-unapplied" notify to the proper main context
This commit fixes up a few race conditions in the GSettingsBackend, mostly with
respect to change notifications occuring at the same time as the last reference
count on a GSettings is dropped. With GDBus feeding us our incoming signals in
a separate thread, this is something that could easily happen.
There is currently no way (near as I can tell) to ensure that a message
has been sent when using GDBus. If we exit() before we are sure, then
it is very possible that the message isn't sent at all. This behaviour
was observed when using the GSettings commandline tool with dconf.
A quick and dirty workaround for now.
Don't define __USE_GNU, thats a glibc-internal macro, and
don't use SOL_SOCKET when not including sys/socket.h.
Maybe this file should be called glinuxcredentialsmessage.c...

This is to match g_dbus_connection_new(). This extension allows us to
extend GDBusAuthObserver to also be used in client-side authentication
in the future (right now it's only used on the server-side).
This is needed to e.g. allow encoding maybe types (once we add
G_DBUS_CAPABILITY_FLAGS_MAYBE_TYPES) if, and only if, that capability
has been negotiated with the peer (via authentication).
This uncovered a bug in name watching if the name wasn't activatable.
Also provoked the need for on_connection variants of g_bus_watch_name
(added g_bus_watch_proxy's variant as well).
Also make the gdbus-example-server include some example
annotations. The output looks like this:

This makes it possible to use the cached properties mechanism even if
constructing the proxy with the DO_NOT_LOAD_PROPERTIES flag.
This is useful for cases where you obtain the and track object
properties out-of-band. For example, in udisks, the plan is to have
something like this
Manager.GetObjects (out ao paths, out aa{sa{sv}} all_properties);
Manager.ObjectAdded (o path, a{sa{sv}} all_properties);
Manager.ObjectChanged (o path, a{sa{sv}} all_properties);
Manager.ObjectRemoved (o path, a{sa{sv}} all_properties);
E.g. the first GetObjects() call will return *all* data about *all*
exported objects. Further, this way a client will only need to listen
these three signals (three AddMatch) on the Manager object and it will
never need to do GetAll() etc (e.g. can use DO_NOT_LOAD_PROPERTIES).
(Of course this only works if the client is interested in all
objects... while this is true for udisks it is generally not true for
other D-Bus services).
Also use expected_interface to check for programming errors.
These are included wholesale in the docs, and the copyright
headers make them even more overwhelming. Plus, we don't have
copyright headers on examples anywhere else.
This fixes a problem with services that doesn't implement GetAll() for
one reason or another.

Lots of people been suggesting this. We still use MethodInvocation /
method_invocation for handling incoming method calls so use call()
instead of invoke_method() helps to separate the client and server

The messages array was not reallocated correctly because it was using

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

explicitly opened for so-called overlapped IO.
The API to create these streams takes Win32 HANDLEs. Not file

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

Define GStatBuf as the type used by g_stat() and g_lstat(). Replaces
the non-public struct tag _g_stat_struct. Mostly relevant for Windows
where there are several variants of stat-style structs. On POSIX, is
just another name for struct stat.
Actually, also on many POSIX systems there are in fact several
variants of struct stat and corresponding stat() and lstat()
functions, but as g_stat and g_lstat are normally on POSIX just macros
that expand to stat and lstat, this should not cause a problem. It's
only when it's the actual g_stat() or g_lstat() implementation inside
GLib that gets called that one needs to be sure the passed struct is
the same as what GLib expects.)
We need to check priv->cancelled after taking the lock. Previously we
