For example, if +Synapse is installed in a virtualenv in <code>~/synapse/env</code> then +run:</p> +<pre><code class="language-bash">source ~/synapse/env/bin/activate +</code></pre> +</li> +<li> +<p>If Synapse was installed using pip then upgrade to the latest +version by running:</p> +<pre><code class="language-bash">pip install --upgrade matrix-synapse +</code></pre> +<p>If Synapse was installed using git then upgrade to the latest +version by running:</p> +<pre><code class="language-bash">git pull +pip install --upgrade . +</code></pre> +</li> +<li> +<p>Restart Synapse:</p> +<pre><code class="language-bash">./synctl restart +</code></pre> +</li> +</ol> +</li> +</ul> +<p>To check whether your update was successful, you can check the running +server version with:</p> +<pre><code class="language-bash"># you may need to replace 'localhost:8008' if synapse is not configured +# to listen on port 8008. + +curl http://localhost:8008/_synapse/admin/v1/server_version +</code></pre> +<h2 id="rolling-back-to-older-versions"><a class="header" href="#rolling-back-to-older-versions">Rolling back to older versions</a></h2> +<p>Rolling back to previous releases can be difficult, due to database +schema changes between releases.

For example, from a <code>psql</code> shell, run the following sql:</p> +<pre><code class="language-sql">SELECT pg_size_pretty(pg_relation_size('events_order_room')); +</code></pre> +<p>We need to rebuild <strong>four</strong> indexes, so you will need to multiply this result +by four to give an estimate of the disk space required.

This introduces +a bit more backwards and forwards between the HS and the client, but +this improves the overall flexibility of the API. You can now GET on +/register to retrieve a list of valid registration flows. Upon choosing +one, they are submitted in the same way as login, e.g:</p> +<pre><code>{ + type: m.login.password, + user: foo, + password: bar +} +</code></pre> +<p>The default HS supports 2 flows, with and without Identity Server email +authentication. Enabling captcha on the HS will add in an extra step to +all flows: <code>m.login.recaptcha</code> which must be completed before you can +transition to the next stage. There is a new login type: +<code>m.login.email.identity</code> which contains the <code>threepidCreds</code> key which +were previously sent in the original register request. For more +information on this, see the specification.</p> +<h2 id="web-client"><a class="header" href="#web-client">Web Client</a></h2> +<p>The VoIP specification has changed between v0.2.0 and v0.3.0. Users +should refresh any browser tabs to get the latest web client code. Users +on v0.2.0 of the web client will not be able to call those on v0.3.0 and +vice versa.</p> +<h1 id="upgrading-to-v020"><a class="header" href="#upgrading-to-v020">Upgrading to v0.2.0</a></h1> +<p>The home server now requires setting up of SSL config before it can run. +To automatically generate default config use:</p> +<pre><code>$ python synapse/app/homeserver.py \ + --server-name machine.my.domain.name \ + --bind-port 8448 \ + --config-path homeserver.config \ + --generate-config +</code></pre> +<p>This config can be edited if desired, for example to specify a different +SSL certificate to use. Once done you can run the home server using:</p> +<pre><code>$ python synapse/app/homeserver.py --config-path homeserver.config +</code></pre> +<p>See the README.rst for more information.</p> +<p>Also note that some config options have been renamed, including:</p> +<ul> +<li>"host" to "server-name"</li> +<li>"database" to "database-path"</li> +<li>"port" to "bind-port" and "unsecure-port"</li> +</ul> +<h1 id="upgrading-to-v001"><a class="header" href="#upgrading-to-v001">Upgrading to v0.0.1</a></h1> +<p>This release completely changes the database schema and so requires +upgrading it before starting the new version of the homeserver.</p> +<p>The script "database-prepare-for-0.0.1.sh" should be used to upgrade +the database. This will save all user information, such as logins and +profiles, but will otherwise purge the database. This includes messages, +which rooms the home server was a member of and room alias mappings.</p> +<p>Before running the command the homeserver should be first completely +shutdown. To run it, simply specify the location of the database, e.g.:</p> +<blockquote> +<p>./scripts/database-prepare-for-0.0.1.sh "homeserver.db"</p> +</blockquote> +<p>Once this has successfully completed it will be safe to restart the +homeserver. You may notice that the homeserver takes a few seconds +longer to restart than usual as it reinitializes the database.</p> +<p>On startup of the new version, users can either rejoin remote rooms +using room aliases or by being reinvited. Alternatively, if any other +homeserver sends a message to a room that the homeserver was previously +in the local HS will automatically rejoin the room.</p> + + </main> + + <nav class="nav-wrapper" aria-label="Page navigation"> + <!-- Mobile navigation buttons --> + + <a rel="prev" href="delegate.html" class="mobile-nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> + <i class="fa fa-angle-left"></i> + </a> + + + + <a rel="next" href="MSC1711_certificates_FAQ.html" class="mobile-nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> + <i class="fa fa-angle-right"></i> + </a> + + + <div style="clear: both"></div> + </nav> + </div> + </div> + + <nav class="nav-wide-wrapper" aria-label="Page navigation"> + + <a rel="prev" href="delegate.html" class="nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> + <i class="fa fa-angle-left"></i> + </a> + + + + <a rel="next" href="MSC1711_certificates_FAQ.html" class="nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> + <i class="fa fa-angle-right"></i> + </a> + + </nav> + + </div> + + + + + + + + + <script type="text/javascript"> + window.playground_copyable = true; + </script> + + + + + + <script src="elasticlunr.min.js" type="text/javascript" charset="utf-8"></script> + <script src="mark.min.js" type="text/javascript" charset="utf-8"></script> + <script src="searcher.js" type="text/javascript" charset="utf-8"></script> + + + <script src="clipboard.min.js" type="text/javascript" charset="utf-8"></script> + <script src="highlight.js" type="text/javascript" charset="utf-8"></script> + <script src="book.js" type="text/javascript" charset="utf-8"></script> + + <!-- Custom JS scripts --> + + <script type="text/javascript" src="docs/website_files/table-of-contents.js"></script> + + + + + </body> +</html> \ No newline at end of file |
