<h1 id="user-directory-api-implementation"><a class="header" href="#user-directory-api-implementation">User Directory API Implementation</a></h1>
|
||
|
|
<p>The user directory is currently maintained based on the 'visible' users
|
||
|
|
on this particular server - i.e. ones which your account shares a room with, or
|
||
|
|
who are present in a publicly viewable room present on the server.</p>
|
||
|
|
<p>The directory info is stored in various tables, which can (typically after
|
||
|
|
DB corruption) get stale or out of sync. If this happens, for now the
|
||
|
|
solution to fix it is to use the <a href="usage/administration/admin_api/background_updates.html#run">admin API</a>
|
||
|
|
and execute the job <code>regenerate_directory</code>. This should then start a background task to
|
||
|
|
flush the current tables and regenerate the directory.</p>
|
||
|
|
<h2 id="data-model"><a class="header" href="#data-model">Data model</a></h2>
|
||
|
|
<p>There are five relevant tables that collectively form the "user directory".
|
||
|
|
Three of them track a master list of all the users we could search for.
|
||
|
|
The last two (collectively called the "search tables") track who can
|
||
|
|
see who.</p>
|
||
|
|
<p>From all of these tables we exclude three types of local user:</p>
|
||
|
|
<ul>
|
||
|
|
<li>support users</li>
|
||
|
|
<li>appservice users</li>
|
||
|
|
<li>deactivated users</li>
|
||
|
|
</ul>
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p><code>user_directory</code>. This contains the user_id, display name and avatar we'll
|
||
|
|
return when you search the directory.</p>
|
||
|
|
<ul>
|
||
|
|
<li>Because there's only one directory entry per user, it's important that we only
|
||
|
|
ever put publicly visible names here. Otherwise we might leak a private
|
||
|
|
nickname or avatar used in a private room.</li>
|
||
|
|
<li>Indexed on rooms. Indexed on users.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p><code>user_directory_search</code>. To be joined to <code>user_directory</code>. It contains an extra
|
||
|
|
column that enables full text search based on user ids and display names.
|
||
|
|
Different schemas for SQLite and Postgres with different code paths to match.</p>
|
||
|
|
<ul>
|
||
|
|
<li>Indexed on the full text search data. Indexed on users.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p><code>user_directory_stream_pos</code>. When the initial background update to populate
|
||
|
|
the directory is complete, we record a stream position here. This indicates
|
||
|
|
that synapse should now listen for room changes and incrementally update
|
||
|
|
the directory where necessary.</p>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p><code>users_in_public_rooms</code>. Contains associations between users and the public rooms they're in.
|
||
|
|
Used to determine which users are in public rooms and should be publicly visible in the directory.</p>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p><code>users_who_share_private_rooms</code>. Rows are triples <code>(L, M, room id)</code> where <code>L</code>
|
||
|
|
is a local user and <code>M</code> is a local or remote user. <code>L</code> and <code>M</code> should be
|
||
|
|
different, but this isn't enforced by a constraint.</p>
|
||
|
