<h1 id="presence-router-callbacks"><a class="header" href="#presence-router-callbacks">Presence router callbacks</a></h1>
|
||
|
|
<p>Presence router callbacks allow module developers to specify additional users (local or remote)
|
||
|
|
to receive certain presence updates from local users. Presence router callbacks can be
|
||
|
|
registered using the module API's <code>register_presence_router_callbacks</code> method.</p>
|
||
|
|
<h2 id="callbacks"><a class="header" href="#callbacks">Callbacks</a></h2>
|
||
|
|
<p>The available presence router callbacks are:</p>
|
||
|
|
<h3 id="get_users_for_states"><a class="header" href="#get_users_for_states"><code>get_users_for_states</code></a></h3>
|
||
|
|
<p><em>First introduced in Synapse v1.42.0</em></p>
|
||
|
|
<pre><code class="language-python">async def get_users_for_states(
|
||
|
|
state_updates: Iterable["synapse.api.UserPresenceState"],
|
||
|
|
) -> Dict[str, Set["synapse.api.UserPresenceState"]]
|
||
|
|
</code></pre>
|
||
|
|
<p><strong>Requires</strong> <code>get_interested_users</code> to also be registered</p>
|
||
|
|
<p>Called when processing updates to the presence state of one or more users. This callback can
|
||
|
|
be used to instruct the server to forward that presence state to specific users. The module
|
||
|
|
must return a dictionary that maps from Matrix user IDs (which can be local or remote) to the
|
||
|
|
<code>UserPresenceState</code> changes that they should be forwarded.</p>
|
||
|
|
<p>Synapse will then attempt to send the specified presence updates to each user when possible.</p>
|
||
|
|
<p>If multiple modules implement this callback, Synapse merges all the dictionaries returned
|
||
|
|
by the callbacks. If multiple callbacks return a dictionary containing the same key,
|
||
|
|
Synapse concatenates the sets associated with this key from each dictionary. </p>

||

<p><em>First introduced in Synapse v1.42.0</em></p>
|
||
|
|
<pre><code class="language-python">async def get_interested_users(
|
||
|
|
user_id: str
|
||
|
|
) -> Union[Set[str], "synapse.module_api.PRESENCE_ALL_USERS"]
|
||
|
|
</code></pre>
|
||
|
|
<p><strong>Requires</strong> <code>get_users_for_states</code> to also be registered</p>
|
||
|
|
<p>Called when determining which users someone should be able to see the presence state of. This
|
||
|
|
callback should return complementary results to <code>get_users_for_state</code> or the presence information
|
||
|
|
may not be properly forwarded.</p>
|
||
|
|
<p>The callback is given the Matrix user ID for a local user that is requesting presence data and
|
||
|
|
should return the Matrix user IDs of the users whose presence state they are allowed to
|
||
|
|
query. The returned users can be local or remote. </p>
|
||
|
|
<p>Alternatively the callback can return <code>synapse.module_api.PRESENCE_ALL_USERS</code>
|
||
|
|
to indicate that the user should receive updates from all known users.</p>
|
||
|
|
<p>If multiple modules implement this callback, they will be considered in order. Synapse
|
||
|
|
calls each callback one by one, and use a concatenation of all the <code>set</code>s returned by the
|
||
|
|
callbacks. If one callback returns <code>synapse.module_api.PRESENCE_ALL_USERS</code>, Synapse uses
|
||
|
|
this value instead. If this happens, Synapse does not call any of the subsequent
|
||
|
|
implementations of this callback.</p>
|
||
|
|
<h2 id="example"><a class="header" href="#example">Example</a></h2>
|
||
|
|
<p>The example below is a module that implements both presence router callbacks, and ensures
|
||
|
|
that <code>@alice:example.org</code> receives all presence updates from <code>@bob:example.com</code> and
|
||
|
|
<code>@charlie:somewhere.org</code>, regardless of whether Alice shares a room with any of them.</p>
