Creates a new #NMClient synchronously.
Note that this will block until a NMClient instance is fully initialized. This does nothing beside calling g_initable_new(). You are free to call g_initable_new() or g_object_new()/g_initable_init() directly for more control, to set GObject properties or get access to the NMClient instance while it is still initializing.
Using the synchronous initialization creates an #NMClient instance that uses an internal #GMainContext. This context is invisible to the user. This introduces an additional overhead that is payed not only during object initialization, but for the entire lifetime of this object. Also, due to this internal #GMainContext, the events are no longer in sync with other messages from #GDBusConnection (but all events of the NMClient will themselves still be ordered). For a serious program, you should therefore avoid these problems by using g_async_initable_init_async() or nm_client_new_async() instead. The sync initialization is still useful for simple scripts or interactive testing for example via pygobject.
Creating an #NMClient instance can only fail for two reasons. First, if you didn't provide a %NM_CLIENT_DBUS_CONNECTION and the call to g_bus_get() fails. You can avoid that by using g_initable_new() directly and set a D-Bus connection. Second, if you cancelled the creation. If you do that, then note that after the failure there might still be idle actions pending which keep nm_client_get_main_context() alive. That means, in that case you must continue iterating the context to avoid leaks. See nm_client_get_context_busy_watcher().
Creating an #NMClient instance when NetworkManager is not running does not cause a failure.
a #GCancellable, or %NULL
The #NMActiveConnection of the activating connection that is likely to become the new #NMClient:primary-connection.
The active connections.
List of both real devices and device placeholders.
If %TRUE, adding and modifying connections is supported.
The list of capabilities numbers as guint32 or %NULL if there are no capabilities. The numeric value correspond to %NMCapability enum.
The list of active checkpoints.
The list of configured connections that are available to the user. (Note that this differs from the underlying D-Bus property, which may also contain the object paths of connections that the user does not have permission to read the details of.)
The network connectivity state.
The used URI for connectivity checking.
The #GDBusConnection to use.
If this is not set during object construction, the D-Bus connection will automatically be chosen during async/sync initalization via g_bus_get().
The name owner of the NetworkManager D-Bus service.
List of real network devices. Does not include placeholder devices.
The current DNS configuration, represented as an array of #NMDnsEntry objects.
The current DNS processing mode.
The current resolv.conf management mode.
The machine hostname stored in persistent configuration. This can be modified by calling nm_client_save_hostname().
#NMClientInstanceFlags for the instance. These affect behavior of #NMClient. This is a construct property and you may only set most flags only during construction.
The flag %NM_CLIENT_INSTANCE_FLAGS_NO_AUTO_FETCH_PERMISSIONS can be toggled any time, even after constructing the instance. Note that you may want to watch NMClient:permissions-state property to know whether permissions are ready. Note that permissions are only fetched when NMClient has a D-Bus name owner.
Whether the connectivity is metered.
Whether networking is enabled.
The property setter is a synchronous D-Bus call. This is deprecated since 1.22.
Whether the daemon is running.
The state of the cached permissions. The value %NM_TERNARY_DEFAULT means that no permissions are yet received (or not yet requested). %NM_TERNARY_TRUE means that permissions are received, cached and up to date. %NM_TERNARY_FALSE means that permissions were received and are cached, but in the meantime a "CheckPermissions" signal was received that invalidated the cached permissions. Note that NMClient will always emit a notify::permissions-state signal when a "CheckPermissions" signal got received or after new permissions got received (that is regardless whether the value of the permission state actually changed). With this you can watch the permissions-state property to know whether the permissions are ready. Note that while NMClient has no D-Bus name owner, no permissions are fetched (and this property won't change).

The property setter is a synchronous D-Bus call. This is deprecated since 1.22.
Whether the WWAN hardware is enabled.
Asynchronously starts a connection to a particular network using the
configuration settings from connection and the network device device.
Certain connection types also take a "specific object" which is the object
path of a connection- specific object, like an #NMAccessPoint for Wi-Fi
connections, or an #NMWimaxNsp for WiMAX connections, to which you wish to
connect. If the specific object is not given, NetworkManager can, in some
cases, automatically determine which network to connect to given the settings
in connection.
If connection is not given for a device-based activation, NetworkManager
picks the best available connection for the device and activates it.
Note that the callback is invoked when NetworkManager has started activating the new connection, not when it finishes. You can use the returned #NMActiveConnection object (in particular, #NMActiveConnection:state) to track the activation to its completion.
an #NMConnection
the #NMDevice
the object path of a connection-type-specific object this activation should use. This parameter is currently ignored for wired and mobile broadband connections, and the value of %NULL should be used (ie, no specific object). For Wi-Fi or WiMAX connections, pass the object path of a #NMAccessPoint or #NMWimaxNsp owned by device, which you can get using nm_object_get_path(), and which will be used to complete the details of the newly added connection.
a #GCancellable, or %NULL
callback to be called when the activation has started
Gets the result of a call to nm_client_activate_connection_async().
the result passed to the #GAsyncReadyCallback
Adds a new connection using the given details (if any) as a template, automatically filling in missing settings with the capabilities of the given device and specific object. The new connection is then asynchronously activated as with nm_client_activate_connection_async(). Cannot be used for VPN connections at this time.
Note that the callback is invoked when NetworkManager has started activating the new connection, not when it finishes. You can used the returned #NMActiveConnection object (in particular, #NMActiveConnection:state) to track the activation to its completion.
This is identical to nm_client_add_and_activate_connection_async() but takes
a further options parameter. Currently, the following options are supported
by the daemon:
an #NMConnection to add; the connection may be partially filled (or even %NULL) and will be completed by NetworkManager using the given device and specific_object before being added
the #NMDevice
the object path of a connection-type-specific object this activation should use. This parameter is currently ignored for wired and mobile broadband connections, and the value of %NULL should be used (i.e., no specific object). For Wi-Fi or WiMAX connections, pass the object path of a #NMAccessPoint or #NMWimaxNsp owned by device, which you can get using nm_object_get_path(), and which will be used to complete the details of the newly added connection.
a #GVariant containing a dictionary with options, or %NULL
a #GCancellable, or %NULL
callback to be called when the activation has started
Gets the result of a call to nm_client_add_and_activate_connection2().
You can call nm_active_connection_get_connection() on the returned #NMActiveConnection to find the path of the created #NMConnection.
the result passed to the #GAsyncReadyCallback
Adds a new connection using the given details (if any) as a template, automatically filling in missing settings with the capabilities of the given device and specific object. The new connection is then asynchronously activated as with nm_client_activate_connection_async(). Cannot be used for VPN connections at this time.
Note that the callback is invoked when NetworkManager has started activating the new connection, not when it finishes. You can used the returned #NMActiveConnection object (in particular, #NMActiveConnection:state) to track the activation to its completion.
an #NMConnection to add; the connection may be partially filled (or even %NULL) and will be completed by NetworkManager using the given device and specific_object before being added
the #NMDevice
the object path of a connection-type-specific object this activation should use. This parameter is currently ignored for wired and mobile broadband connections, and the value of %NULL should be used (ie, no specific object). For Wi-Fi or WiMAX connections, pass the object path of a #NMAccessPoint or #NMWimaxNsp owned by device, which you can get using nm_object_get_path(), and which will be used to complete the details of the newly added connection. If the variant is floating, it will be consumed.
a #GCancellable, or %NULL
callback to be called when the activation has started
Gets the result of a call to nm_client_add_and_activate_connection_async().
You can call nm_active_connection_get_connection() on the returned #NMActiveConnection to find the path of the created #NMConnection.

Call AddConnection2() D-Bus API asynchronously.
the "a{sa{sv}}" #GVariant with the content of the setting.
the %NMSettingsAddConnection2Flags argument.
the "a{sv}" #GVariant with extra argument or %NULL for no extra arguments.
this function wraps AddConnection2(), which has an additional result "a{sv}" output parameter. By setting this to %TRUE, you signal that you are not interested in that output parameter. This allows the function to fall back to AddConnection() and AddConnectionUnsaved(), which is interesting if you run against an older server version that does not yet provide AddConnection2(). By setting this to %FALSE, the function under the hood always calls AddConnection2().
a #GCancellable, or %NULL
callback to be called when the add operation completes
Requests that the remote settings service add the given settings to a new
connection. If save_to_disk is %TRUE, the connection is immediately written
to disk; otherwise it is initially only stored in memory, but may be saved
later by calling the connection's nm_remote_connection_commit_changes()
method.
connection is untouched by this function and only serves as a template of
the settings to add. The #NMRemoteConnection object that represents what
NetworkManager actually added is returned to callback when the addition
operation is complete.
Note that the #NMRemoteConnection returned in callback may not contain
identical settings to connection as NetworkManager may perform automatic
completion and/or normalization of connection properties.

Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

Call g_dbus_connection_call() on the current name owner with the specified arguments. Most importantly, this invokes g_dbus_connection_call() with the client's #GMainContext, so that the response is always in order with other events D-Bus events. Of course, the call uses #GTask and will invoke the callback on the current g_main_context_get_thread_default().
This API is merely a convenient wrapper for g_dbus_connection_call(). You can also use g_dbus_connection_call() directly, with the same effect.

This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
#GObject::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Gets the #NMActiveConnection corresponding to a currently-activating connection that is expected to become the new #NMClient:primary-connection upon successful activation.
Gets the active connections.
Gets both real devices and device placeholders (eg, software devices which do not currently exist, but could be created automatically by NetworkManager if one of their NMDevice::ActivatableConnections was activated). Use nm_device_is_real() to determine whether each device is a real device or a placeholder.
Use nm_device_get_type() or the NM_IS_DEVICE_XXXX() functions to determine what kind of device each member of the returned array is, and then you may use device-specific methods such as nm_device_ethernet_get_hw_address().
Gets all the active checkpoints.

Returns the %NMRemoteConnection representing the connection at path.

Gets a named field from the objects table of associations (see g_object_set_data()).

The #NMClient instance is permanently associated with the current thread default #GMainContext, referenced the time when the instance was created. To receive events, the user must iterate this context and can use it to synchronize access to the client.
Note that even after #NMClient instance got destroyed, there might still be pending sources registered in the context. That means, to fully clean up, the user must continue iterating the context as long as the nm_client_get_context_busy_watcher() object is alive.
Determines whether the daemon is running.
Requests the result of a specific permission, which indicates whether the client can or cannot perform the action the permission represents
the permission for which to return the result, one of #NMClientPermission
Gets the #NMActiveConnection corresponding to the primary active network device.
In particular, when there is no VPN active, or the VPN does not have the default route, this returns the active connection that has the default route. If there is a VPN active with the default route, then this function returns the active connection that contains the route to the VPN endpoint.
If there is no default route, or the default route is over a non-NetworkManager-recognized device, this will return %NULL.
Gets a property of an object.
The value can be:
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

properties are passed in.

Initializes the object implementing the interface.
This method is intended for language bindings. If writing in C, g_initable_new() should typically be used instead.
The object must be initialized before any real use after initial construction, either with this function or g_async_initable_init_async().
Implementations may also support cancellation. If cancellable is not %NULL,
then initialization can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error
%G_IO_ERROR_CANCELLED will be returned. If cancellable is not %NULL and
the object doesn't support cancellable initialization the error
%G_IO_ERROR_NOT_SUPPORTED will be returned.
If the object is not initialized, or initialization returns with an error, then all operations on the object except g_object_ref() and g_object_unref() are considered to be invalid, and have undefined behaviour. See the [introduction][ginitable] for more details.
Callers should not assume that a class which implements #GInitable can be initialized multiple times, unless the class explicitly documents itself as supporting this. Generally, a class’ implementation of init() can assume (and assert) that it will only be called once. Previously, this documentation recommended all #GInitable implementations should be idempotent; that recommendation was relaxed in GLib 2.54.
If a class explicitly supports being initialized multiple times, it is recommended that the method is idempotent: multiple calls with the same arguments should return the same results. Only the first call initializes the object; further calls return the result of the first call.
One reason why a class might need to support idempotent initialization is if it is designed to be used via the singleton pattern, with a #GObjectClass.constructor that sometimes returns an existing instance. In this pattern, a caller would expect to be able to call g_initable_init() on the result of g_object_new(), regardless of whether it is in fact a new instance.
optional #GCancellable object, %NULL to ignore.
Starts asynchronous initialization of the object implementing the interface. This must be done before any real use of the object after initial construction. If the object also implements #GInitable you can optionally call g_initable_init() instead.
This method is intended for language bindings. If writing in C, g_async_initable_new_async() should typically be used instead.
When the initialization is finished, callback will be called. You can
then call g_async_initable_init_finish() to get the result of the
initialization.
Implementations may also support cancellation. If cancellable is not
%NULL, then initialization can be cancelled by triggering the cancellable
object from another thread. If the operation was cancelled, the error
%G_IO_ERROR_CANCELLED will be returned. If cancellable is not %NULL, and
the object doesn't support cancellable initialization, the error
%G_IO_ERROR_NOT_SUPPORTED will be returned.
As with #GInitable, if the object is not initialized, or initialization returns with an error, then all operations on the object except g_object_ref() and g_object_unref() are considered to be invalid, and have undefined behaviour. They will often fail with g_critical() or g_warning(), but this must not be relied on.
Callers should not assume that a class which implements #GAsyncInitable can be initialized multiple times; for more information, see g_initable_init(). If a class explicitly supports being initialized multiple times, implementation requires yielding all subsequent calls to init_async() on the results of the first call.
For classes that also support the #GInitable interface, the default implementation of this method will run the g_initable_init() function in a thread, so if you want to support asynchronous initialization via threads, just implement the #GAsyncInitable interface without overriding any interface methods.

Requests that the remote settings service load or reload the given files, adding or updating the connections described within.
The changes to the indicated files will not yet be reflected in
client's connections array when the function returns.
If all of the indicated files were successfully loaded, the
function will return %TRUE, and failures will be set to %NULL. If
NetworkManager tried to load the files, but some (or all) failed,
then failures will be set to a %NULL-terminated array of the
filenames that failed to load.

Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than g_object_notify().
One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the #GParamSpec of a property installed on the class of object.
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
Reload NetworkManager's configuration and perform certain updates, like
flushing caches or rewriting external state to disk. This is similar to
sending SIGHUP to NetworkManager but it allows for more fine-grained control
over what to reload (see flags). It also allows non-root access via
PolicyKit and contrary to signals it is synchronous.

Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.

g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().
A #GQuark, naming the user data pointer
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
Initializes the object implementing the interface.
This method is intended for language bindings. If writing in C, g_initable_new() should typically be used instead.
The object must be initialized before any real use after initial construction, either with this function or g_async_initable_init_async().
Implementations may also support cancellation. If cancellable is not %NULL,
then initialization can be cancelled by triggering the cancellable object
from another thread. If the operation was cancelled, the error
%G_IO_ERROR_CANCELLED will be returned. If cancellable is not %NULL and
the object doesn't support cancellable initialization the error
%G_IO_ERROR_NOT_SUPPORTED will be returned.
If the object is not initialized, or initialization returns with an error, then all operations on the object except g_object_ref() and g_object_unref() are considered to be invalid, and have undefined behaviour. See the [introduction][ginitable] for more details.
Callers should not assume that a class which implements #GInitable can be initialized multiple times, unless the class explicitly documents itself as supporting this. Generally, a class’ implementation of init() can assume (and assert) that it will only be called once. Previously, this documentation recommended all #GInitable implementations should be idempotent; that recommendation was relaxed in GLib 2.54.
If a class explicitly supports being initialized multiple times, it is recommended that the method is idempotent: multiple calls with the same arguments should return the same results. Only the first call initializes the object; further calls return the result of the first call.
One reason why a class might need to support idempotent initialization is if it is designed to be used via the singleton pattern, with a #GObjectClass.constructor that sometimes returns an existing instance. In this pattern, a caller would expect to be able to call g_initable_init() on the result of g_object_new(), regardless of whether it is in fact a new instance.
optional #GCancellable object, %NULL to ignore.
Starts asynchronous initialization of the object implementing the interface. This must be done before any real use of the object after initial construction. If the object also implements #GInitable you can optionally call g_initable_init() instead.
This method is intended for language bindings. If writing in C, g_async_initable_new_async() should typically be used instead.
When the initialization is finished, callback will be called. You can
then call g_async_initable_init_finish() to get the result of the
initialization.
Implementations may also support cancellation. If cancellable is not
%NULL, then initialization can be cancelled by triggering the cancellable
object from another thread. If the operation was cancelled, the error
%G_IO_ERROR_CANCELLED will be returned. If cancellable is not %NULL, and
the object doesn't support cancellable initialization, the error
%G_IO_ERROR_NOT_SUPPORTED will be returned.
As with #GInitable, if the object is not initialized, or initialization returns with an error, then all operations on the object except g_object_ref() and g_object_unref() are considered to be invalid, and have undefined behaviour. They will often fail with g_critical() or g_warning(), but this must not be relied on.
Callers should not assume that a class which implements #GAsyncInitable can be initialized multiple times; for more information, see g_initable_init(). If a class explicitly supports being initialized multiple times, implementation requires yielding all subsequent calls to init_async() on the results of the first call.
For classes that also support the #GInitable interface, the default implementation of this method will run the g_initable_init() function in a thread, so if you want to support asynchronous initialization via threads, just implement the #GAsyncInitable interface without overriding any interface methods.

Finishes asynchronous initialization and returns the result. See g_async_initable_init_async().
a #GAsyncResult.
Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

name of a property to look up.
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
#GTypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.

Creates a new #NMClient synchronously.
Note that this will block until a NMClient instance is fully initialized. This does nothing beside calling g_initable_new(). You are free to call g_initable_new() or g_object_new()/g_initable_init() directly for more control, to set GObject properties or get access to the NMClient instance while it is still initializing.
Using the synchronous initialization creates an #NMClient instance that uses an internal #GMainContext. This context is invisible to the user. This introduces an additional overhead that is payed not only during object initialization, but for the entire lifetime of this object. Also, due to this internal #GMainContext, the events are no longer in sync with other messages from #GDBusConnection (but all events of the NMClient will themselves still be ordered). For a serious program, you should therefore avoid these problems by using g_async_initable_init_async() or nm_client_new_async() instead. The sync initialization is still useful for simple scripts or interactive testing for example via pygobject.
Creating an #NMClient instance can only fail for two reasons. First, if you didn't provide a %NM_CLIENT_DBUS_CONNECTION and the call to g_bus_get() fails. You can avoid that by using g_initable_new() directly and set a D-Bus connection. Second, if you cancelled the creation. If you do that, then note that after the failure there might still be idle actions pending which keep nm_client_get_main_context() alive. That means, in that case you must continue iterating the context to avoid leaks. See nm_client_get_context_busy_watcher().

NMClient contains a cache of the objects of NetworkManager's D-Bus API. It uses #GMainContext and #GDBusConnection for that and registers to D-Bus signals. That means, when iterating the associated #GMainContext, D-Bus signals gets processed and the #NMClient instance updates and emits #GObject signals.
