Also document which fields require such a check in order to have correct
threading semantics.
This usage doesn't matches the GInitable documentation, which suggests
use of a GError - but using an uninitialized GDBusConnection is
programming error, and not usefully recoverable. (The GInitable
documentation may have been a mistake - GNOME#662208.) Also, not all of
the places where we need it can raise a GError.
The check serves a dual purpose: it turns a non-deterministic crash into
a deterministic critical warning, and is also a memory barrier for
thread-safety. All of these functions dereference or return fields that
are meant to be protected by FLAG_INITIALIZED, so they could crash or
return an undefined value to their caller without this, if called from a
thread that isn't the one that called initable_init() (although I can't
think of any way to do that without encountering a memory barrier,
undefined behaviour, or a race condition that leads to undefined
behaviour if the non-initializing thread wins the race).
One exception is that initable_init() itself makes a synchronous call.
We deal with that by passing new internal flags up the call stack, to
reassure g_dbus_connection_send_message_unlocked() that it can go ahead.

* Load modules from paths listed in GIO_EXTRA_MODULES environment

* Ignore duplicate modules based on module basename.
* Add the concept of GIOModuleScope which allows other callers to
skip duplicate loaded modules, or block specific modules based on
basename.
* Document behavior.

* Since we're breaking unreleased API, expand amount of padding

The database is an abstract object implemented by the various TLS
backends, which is used by GTlsConnection to lookup certificates
and keys, as well as verify certificate chains.
Also add GTlsInteraction, which can be used to prompt the user
for a password or PIN (used with the database).

Add a flag to essentially short-circuit g_application_register(). The
application makes no attempt to acquire the bus name or check for
existing instances with that name. The application is never considered
as being 'remote' and all requests are handled locally.
Closes#646985.
Trying to do this as a signal won't work well with either
GTlsCertificateDB (in which case looking up a certificate in the db is
a blocking/asynchronous act) or session resumption support (in which
case the certificate or lack thereof is part of the session definition
and so needs to be known immediately). Make the caller use
g_tls_connection_set_certificate() ahead of time (or when retrying)
instead.
This adds an extension point for TLS connections to gio, with a
gnutls-based implementation in glib-networking.
Full TLS support is still a work in progress; the current API is
missing some features, and parts of it may still be changed before
2.28.

If specified, the signal subscription is setup client-side but the match
rule is not sent to the server. This allows the caller to manually
register more detailed match rules.
Add support for passing the full contents of the environment to the
primary instance (by storing it in the platform_data) when
G_APPLICATION_SEND_ENVIRONMENT is in the flags.
Rework filter functions as per
https://bugzilla.gnome.org/show_bug.cgi?id=624546#c8
This commit breaks ABI. However, this ABI break affects only
applications using filter functions. The only known user of is dconf.

Allow modifying a GDBusMessage in a filter function and also add tests
for this. This breaks API but leaves ABI (almost) intact - at least
dconf's GSettings backend (the only big user I know of) will keep
working.

Also use this in the test cases to check that serialization to and

- Make GCredentials instance and class structures private so it can't
be subclassed and we don't have to worry about ABI compat
issues. This also allows us to get rid of the GCredentialsPrivate
struct.
- Add a GCredentialsType enumeration that is used whenever exchanging
pointers with the user. This allows us to support OSes with
multiple native credential types. In particular, it allows
supporting OSes where the native credential evolves or even changes
over time.
- Add g_socket_get_credentials() method.
- Add tests for g_socket_get_credentials(). Right now this is in the
GDBus peer-to-peer test case but we can change that later.
- Move GTcpConnection into a separate gtk-doc page as was already
half-done with GUnixConnection. Also finish the GUnixConnection
move and ensure send_credentials() and receive_credentials()
methods are in the docs. Also nuke comment about GTcpConnection
being empty compared to its superclass.

This is preferable to the current magical solution whereby the serial
is only rewritten if non-zero. In particular, it makes it easier to
send the same message on multiple connections without having to reset
the serial number.

This is currently unused but might be useful in the future. For
example, it might be nice with a way to bypass the current queue of
outgoing messages - having a flag enumeration allows us to add a
G_DBUS_SEND_MESSAGE_FLAGS_BYPASS_QUEUE etc. etc.
This commit breaks ABI and API. Users of the (rarely used) API to send
messages will have to port to this new API.

This is currently unused but will probably be useful in the
future. For example, we could have a _ARG0_IS_PATH to specify that
arg0 should be used for arg0path.
This commit breaks API and ABI. Users of
g_dbus_connection_signal_subscribe() will need to port to this new
version.

Without this guarantee, peer-to-peer connections are not very
useful. However, with this guarantee it's possible to export objects
in a handler for the GDBusServer::new-connection signal.
There are two caveats with this patch
- it won't work on message bus connections
- we don't queue up messages to be written
that can be addresses later if needed.

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.

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
facilities. Which is a good thing(tm).
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.
