This was mostly machine generated with the following command:
```
codespell \
--builtin clear,rare,usage \
--skip './po/*' --skip './.git/*' --skip './NEWS*' \
--write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).
Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.
There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.
If I’ve missed anything, please file an issue!

/**
|
||
* SECTION:gdbusobjectmanagerclient
|
||
* @short_description: Client-side object manager
|
||
* @include: gio/gio.h
|
||
*
|
||
* #GDBusObjectManagerClient is used to create, monitor and delete object
|
||
* proxies for remote objects exported by a #GDBusObjectManagerServer (or any
|
||
* code implementing the
|
||
* [org.freedesktop.DBus.ObjectManager](http://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-objectmanager)
|
||
* interface).
|
||
*
|
||
* Once an instance of this type has been created, you can connect to
|
||
* the #GDBusObjectManager::object-added and
|
||
* #GDBusObjectManager::object-removed signals and inspect the
|
||
* #GDBusObjectProxy objects returned by
|
||
* g_dbus_object_manager_get_objects().
|
||
*
|
||
* If the name for a #GDBusObjectManagerClient is not owned by anyone at
|
||
* object construction time, the default behavior is to request the
|
||
* message bus to launch an owner for the name. This behavior can be
|
||
* disabled using the %G_DBUS_OBJECT_MANAGER_CLIENT_FLAGS_DO_NOT_AUTO_START
|
||
* flag. It's also worth noting that this only works if the name of
|
||
* interest is activatable in the first place. E.g. in some cases it
|
||
* is not possible to launch an owner for the requested name. In this
|
||
* case, #GDBusObjectManagerClient object construction still succeeds but
|
||
* there will be no object proxies
|
||
* (e.g. g_dbus_object_manager_get_objects() returns the empty list) and
|
||
* the #GDBusObjectManagerClient:name-owner property is %NULL.
|
||
*
|
||
* The owner of the requested name can come and go (for example
|
||
* consider a system service being restarted) – #GDBusObjectManagerClient
|
||
* handles this case too; simply connect to the #GObject::notify
|
||
* signal to watch for changes on the #GDBusObjectManagerClient:name-owner
|
||
* property. When the name owner vanishes, the behavior is that
|
||
* #GDBusObjectManagerClient:name-owner is set to %NULL (this includes
|
||
* emission of the #GObject::notify signal) and then
|
||
* #GDBusObjectManager::object-removed signals are synthesized
|
||
* for all currently existing object proxies. Since
|
||
* #GDBusObjectManagerClient:name-owner is %NULL when this happens, you can
|
||
* use this information to disambiguate a synthesized signal from a
|
||
* genuine signal caused by object removal on the remote
|
||
* #GDBusObjectManager. Similarly, when a new name owner appears,
|
||
* #GDBusObjectManager::object-added signals are synthesized
|
||
* while #GDBusObjectManagerClient:name-owner is still %NULL. Only when all
|
||
* object proxies have been added, the #GDBusObjectManagerClient:name-owner
|
||
* is set to the new name owner (this includes emission of the
|
||
* #GObject::notify signal). Furthermore, you are guaranteed that
|
||
* #GDBusObjectManagerClient:name-owner will alternate between a name owner
|
||
* (e.g. `:1.42`) and %NULL even in the case where
|
||
* the name of interest is atomically replaced
|
||
*
|
||
* Ultimately, #GDBusObjectManagerClient is used to obtain #GDBusProxy
|
||
* instances. All signals (including the
|
||
* org.freedesktop.DBus.Properties::PropertiesChanged signal)
|
||
* delivered to #GDBusProxy instances are guaranteed to originate
|
||
* from the name owner. This guarantee along with the behavior
|
||
* described above, means that certain race conditions including the
|
||
* "half the proxy is from the old owner and the other half is from
|
||
* the new owner" problem cannot happen.
|
||
*
|
||
* To avoid having the application connect to signals on the returned
|
||
* #GDBusObjectProxy and #GDBusProxy objects, the
|
||
* #GDBusObject::interface-added,
|
||
* #GDBusObject::interface-removed,
|
||
* #GDBusProxy::g-properties-changed and
|
||
* #GDBusProxy::g-signal signals
|
||
* are also emitted on the #GDBusObjectManagerClient instance managing these
|
||
* objects. The signals emitted are
|
||
* #GDBusObjectManager::interface-added,
|
||
* #GDBusObjectManager::interface-removed,
|
||
* #GDBusObjectManagerClient::interface-proxy-properties-changed and
|
||
* #GDBusObjectManagerClient::interface-proxy-signal.
|
||
*
|
||
* Note that all callbacks and signals are emitted in the
|
||
* [thread-default main context][g-main-context-push-thread-default]
|
||
* that the #GDBusObjectManagerClient object was constructed
|
||
* in. Additionally, the #GDBusObjectProxy and #GDBusProxy objects
|
||
* originating from the #GDBusObjectManagerClient object will be created in
|
||
* the same context and, consequently, will deliver signals in the
|
||
* same main loop.
