<h1 id="upgrading-synapse"><a class="header" href="#upgrading-synapse">Upgrading Synapse</a></h1>
|
|
<p>Before upgrading check if any special steps are required to upgrade from
|
|
the version you currently have installed to the current version of
|
|
Synapse. The extra instructions that may be required are listed later in
|
|
this document.</p>
|
|
<ul>
|
|
<li>
|
|
<p>Check that your versions of Python and PostgreSQL are still
|
|
supported.</p>
|
|
<p>Synapse follows upstream lifecycles for <a href="https://endoflife.date/python">Python</a> and
|
|
<a href="https://endoflife.date/postgresql">PostgreSQL</a>, and removes support for versions
|
|
which are no longer maintained.</p>
|
|
<p>The website <a href="https://endoflife.date">https://endoflife.date</a> also offers convenient
|
|
summaries.</p>
|
|
</li>
|
|
<li>
|
|
<p>If Synapse was installed using <a href="../setup/INSTALL.html#prebuilt-packages">prebuilt
|
|
packages</a>, you will need to follow the
|
|
normal process for upgrading those packages.</p>
|
|
</li>
|
|
<li>
|
|
<p>If Synapse was installed from source, then:</p>
|
|
<ol>
|
|
<li>
|
|
<p>Activate the virtualenv before upgrading. 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. Where we have been able to test the
|
|
rollback process, this will be noted below.</p>
|
|
<p>In general, you will need to undo any changes made during the upgrade
|
|
process, for example:</p>
|
|
<ul>
|
|
<li>
|
|
<p>pip:</p>
|
|
<pre><code class="language-bash">source env/bin/activate
|
|
# replace `1.3.0` accordingly:
|
|
pip install matrix-synapse==1.3.0
|
|
</code></pre>
|
|
</li>
|
|
<li>
|
|
<p>Debian:</p>
|
|
<pre><code class="language-bash"># replace `1.3.0` and `stretch` accordingly:
|
|
wget https://packages.matrix.org/debian/pool/main/m/matrix-synapse-py3/matrix-synapse-py3_1.3.0+stretch1_amd64.deb
|
|
dpkg -i matrix-synapse-py3_1.3.0+stretch1_amd64.deb
|
|
</code></pre>
|
|
</li>
|
|
</ul>

<h2 id="deprecation-of-the-current-spam-checker-interface"><a class="header" href="#deprecation-of-the-current-spam-checker-interface">Deprecation of the current spam checker interface</a></h2>
|
|
<p>The current spam checker interface is deprecated in favour of a new generic modules system.
|
|
Authors of spam checker modules can refer to <a href="https://matrix-org.github.io/synapse/develop/modules.html#porting-an-existing-module-that-uses-the-old-interface">this
|
|
documentation</a>
|
|
to update their modules. Synapse administrators can refer to <a href="https://matrix-org.github.io/synapse/develop/modules.html#using-modules">this
|
|
documentation</a>
|
|
to update their configuration once the modules they are using have been updated.</p>
|
|
<p>We plan to remove support for the current spam checker interface in August 2021.</p>
|
|
<p>More module interfaces will be ported over to this new generic system in future versions
|
|
of Synapse.</p>
|
|
<h1 id="upgrading-to-v1340"><a class="header" href="#upgrading-to-v1340">Upgrading to v1.34.0</a></h1>
|
|
<h2 id="room_invite_state_types-configuration-setting"><a class="header" href="#room_invite_state_types-configuration-setting"><code>room_invite_state_types</code> configuration setting</a></h2>
|
|
<p>The <code>room_invite_state_types</code> configuration setting has been deprecated
|
|
and replaced with <code>room_prejoin_state</code>. See the <a href="https://github.com/matrix-org/synapse/blob/v1.34.0/docs/sample_config.yaml#L1515">sample configuration
|
|
file</a>.</p>
|
|
<p>If you have set <code>room_invite_state_types</code> to the default value you
|
|
should simply remove it from your configuration file. The default value
|
|
used to be:</p>
|
|
<pre><code class="language-yaml">room_invite_state_types:
|
|
- "m.room.join_rules"
|
|
- "m.room.canonical_alias"
|
|
- "m.room.avatar"
|
|
- "m.room.encryption"
|
|
- "m.room.name"
|
|
</code></pre>
|
|
<p>If you have customised this value, you should remove
|
|
<code>room_invite_state_types</code> and configure <code>room_prejoin_state</code> instead.</p>
|
|
<h1 id="upgrading-to-v1330"><a class="header" href="#upgrading-to-v1330">Upgrading to v1.33.0</a></h1>
|
|
<h2 id="account-validity-html-templates-can-now-display-a-users-expiration-date"><a class="header" href="#account-validity-html-templates-can-now-display-a-users-expiration-date">Account Validity HTML templates can now display a user's expiration date</a></h2>
|
|
<p>This may affect you if you have enabled the account validity feature,
|
|
and have made use of a custom HTML template specified by the
|
|
<code>account_validity.template_dir</code> or
|
|
<code>account_validity.account_renewed_html_path</code> Synapse config options.</p>
|
|
<p>The template can now accept an <code>expiration_ts</code> variable, which
|
|
represents the unix timestamp in milliseconds for the future date of
|
|
which their account has been renewed until. See the <a href="https://github.com/matrix-org/synapse/blob/release-v1.33.0/synapse/res/templates/account_renewed.html">default
|
|
template</a>
|
|
for an example of usage.</p>
|
|
<p>ALso note that a new HTML template, <code>account_previously_renewed.html</code>,
|
|
has been added. This is is shown to users when they attempt to renew
|
|
their account with a valid renewal token that has already been used

|
|
<p>When using Synapse with a reverse proxy (in particular, when using the
|
|
[x_forwarded]{.title-ref} option on an HTTP listener), Synapse now
|
|
expects to receive an [X-Forwarded-Proto]{.title-ref} header on incoming
|
|
HTTP requests. If it is not set, Synapse will log a warning on each
|
|
received request.</p>
|
|
<p>To avoid the warning, administrators using a reverse proxy should ensure
|
|
that the reverse proxy sets [X-Forwarded-Proto]{.title-ref} header to
|
|
[https]{.title-ref} or [http]{.title-ref} to indicate the protocol used
|
|
by the client.</p>
|
|
<p>Synapse also requires the [Host]{.title-ref} header to be preserved.</p>
|
|
<p>See the <a href="../reverse_proxy.html">reverse proxy documentation</a>, where the
|
|
example configurations have been updated to show how to set these
|
|
headers.</p>
|
|
<p>(Users of <a href="https://caddyserver.com/">Caddy</a> are unaffected, since we
|

believe it sets [X-Forwarded-Proto]{.title-ref} by default.)</p>

<p>This version changes the URI used for callbacks from OAuth2 and SAML2

identity providers:</p>
|
|
<ul>
|
|
<li>
|
|
<p>If your server is configured for single sign-on via an OpenID
|
|
Connect or OAuth2 identity provider, you will need to add
|
|
<code>[synapse public baseurl]/_synapse/client/oidc/callback</code> to the list
|
|
of permitted "redirect URIs" at the identity provider.</p>
|
|
<p>See the <a href="../openid.html">OpenID docs</a> for more information on setting
|
|
up OpenID Connect.</p>
|
|
</li>
|
|
<li>
|
|
<p>If your server is configured for single sign-on via a SAML2 identity
|
|
provider, you will need to add
|
|
<code>[synapse public baseurl]/_synapse/client/saml2/authn_response</code> as a
|
|
permitted "ACS location" (also known as "allowed callback URLs")
|
|
at the identity provider.</p>
|
|
<p>The "Issuer" in the "AuthnRequest" to the SAML2 identity
|
|
provider is also updated to
|
|
<code>[synapse public baseurl]/_synapse/client/saml2/metadata.xml</code>. If
|
|
your SAML2 identity provider uses this property to validate or
|
|
otherwise identify Synapse, its configuration will need to be
|
|
updated to use the new URL. Alternatively you could create a new,
|
|
separate "EntityDescriptor" in your SAML2 identity provider with
|
|
the new URLs and leave the URLs in the existing "EntityDescriptor"

as they were.</p>

|
|
<p>v1.26.0 includes a lot of large changes. If something problematic
|
|
occurs, you may want to roll-back to a previous version of Synapse.
|
|
Because v1.26.0 also includes a new database schema version, reverting
|
|
that version is also required alongside the generic rollback
|
|
instructions mentioned above. In short, to roll back to v1.25.0 you need
|
|
to:</p>
|
|
<ol>
|
|
<li>
|
|
<p>Stop the server</p>
|
|
</li>
|
|
<li>
|
|
<p>Decrease the schema version in the database:</p>
|
|
<pre><code class="language-sql">UPDATE schema_version SET version = 58;
|
|
</code></pre>
|
|
</li>
|
|
<li>
|
|
<p>Delete the ignored users & chain cover data:</p>
|

|
|
DELETE FROM event_auth_chains;
|
|
</code></pre>
|
|
</li>
|
|
<li>
|
|
<p>Mark the deltas as not run (so they will re-run on upgrade).</p>
|

<h2 id="blacklisting-ip-ranges"><a class="header" href="#blacklisting-ip-ranges">Blacklisting IP ranges</a></h2>

federation, identity servers, push, and for checking key validity for
|
|
third-party invite events. The previous setting,

<code>federation_ip_range_blacklist</code>, is deprecated. The new

<p>If you have never customised <code>federation_ip_range_blacklist</code> it is

|
|
<p>This release allows the OpenID Connect mapping provider to perform
|
|
normalisation of the localpart of the Matrix ID. This allows for the
|
|
mapping provider to specify different algorithms, instead of the
|
|
<a href="https://matrix.org/docs/spec/appendices#mapping-from-other-character-sets">default
|
|
way</a>.</p>
|
|
<p>If your Synapse configuration uses a custom mapping provider
|
|
([oidc_config.user_mapping_provider.module]{.title-ref} is specified and
|
|
not equal to
|
|
[synapse.handlers.oidc_handler.JinjaOidcMappingProvider]{.title-ref})
|
|
then you <em>must</em> ensure that [map_user_attributes]{.title-ref} of the
|
|
mapping provider performs some normalisation of the
|
|
[localpart]{.title-ref} returned. To match previous behaviour you can
|
|
use the [map_username_to_mxid_localpart]{.title-ref} function provided
|
|
by Synapse. An example is shown below:</p>
|
|
<pre><code class="language-python">from synapse.types import map_username_to_mxid_localpart
|
|
|
|
class MyMappingProvider:
|
|
def map_user_attributes(self, userinfo, token):

|
# ... your custom logic ...
|
|
sso_user_id = ...
|

localpart = map_username_to_mxid_localpart(sso_user_id)

return {"localpart": localpart}

<p>Historically, the Synapse Admin API has been accessible under:</p>
|
|
<ul>
|
|
<li><code>/_matrix/client/api/v1/admin</code></li>
|
|
<li><code>/_matrix/client/unstable/admin</code></li>
|
|
<li><code>/_matrix/client/r0/admin</code></li>
|
|
<li><code>/_synapse/admin/v1</code></li>
|
|
</ul>
|
|
<p>The endpoints with <code>/_matrix/client/*</code> prefixes have been removed as of
|
|
v1.24.0. The Admin API is now only accessible under:</p>
|
|
<ul>
|
|
<li><code>/_synapse/admin/v1</code></li>
|
|
</ul>
|
|
<p>The only exception is the [/admin/whois]{.title-ref} endpoint, which is

|
|
<p>The deprecation of the old endpoints was announced with Synapse 1.20.0

|
|
<p>The <code>http_client</code> argument is no longer passed to modules as they are

|
initialised. Instead, modules are expected to make use of the
|
|
<code>http_client</code> property on the <code>ModuleApi</code> class. Modules are now passed
|
|
a <code>module_api</code> argument during initialisation, which is an instance of

|
<p>A bug was introduced in Synapse 1.4.0 which could cause the room
|
|
directory to be incomplete or empty if Synapse was upgraded directly
|
|
from v1.2.1 or earlier, to versions between v1.4.0 and v1.12.x.</p>
|
|
<p>This will <em>not</em> be a problem for Synapse installations which were:</p>
|
|
<p>: - created at v1.4.0 or later,
|
|
- upgraded via v1.3.x, or
|
|
- upgraded straight from v1.2.1 or earlier to v1.13.0 or later.</p>
|
|
<p>If completeness of the room directory is a concern, installations which
|
|
are affected can be repaired as follows:</p>
|
|
<ol>
|
|
<li>
|
|
<p>Run the following sql from a [psql]{.title-ref} or
|
|
[sqlite3]{.title-ref} console:</p>

|
|
<p>v1.13.0 includes a lot of large changes. If something problematic
|
|
occurs, you may want to roll-back to a previous version of Synapse.
|
|
Because v1.13.0 also includes a new database schema version, reverting
|
|
that version is also required alongside the generic rollback
|
|
instructions mentioned above. In short, to roll back to v1.12.4 you need
|
|
to:</p>
|
|
<ol>
|
|
<li>
|
|
<p>Stop the server</p>
|
|
</li>
|
|
<li>

|
|
</li>
|
|
<li>

|
|
<h1 id="upgrading-to-v1120"><a class="header" href="#upgrading-to-v1120">Upgrading to v1.12.0</a></h1>
|
|
<p>This version includes a database update which is run as part of the
|
|
upgrade, and which may take some time (several hours in the case of a
|
|
large server). Synapse will not respond to HTTP requests while this
|
|
update is taking place.</p>
|
|
<p>This is only likely to be a problem in the case of a server which is
|
|
participating in many rooms.</p>
|
|
<ol start="0">
|
|
<li>
|
|
<p>As with all upgrades, it is recommended that you have a recent
|
|
backup of your database which can be used for recovery in the event
|
|
of any problems.</p>
|
|
</li>
|
|
<li>
|
|
<p>As an initial check to see if you will be affected, you can try
|
|
running the following query from the [psql]{.title-ref} or
|
|
[sqlite3]{.title-ref} console. It is safe to run it while Synapse is
|
|
still running.</p>
|
|
<pre><code class="language-sql">SELECT MAX(q.v) FROM (
|
|
SELECT (
|
|
SELECT ej.json AS v
|

WHERE se.room_id=rooms.room_id AND se.type='m.room.create' AND se.state_key=''
|
|
LIMIT 1
|
|
) FROM rooms WHERE rooms.room_version IS NULL
|
|
) q;
|
|
</code></pre>
|
|
<p>This query will take about the same amount of time as the upgrade
|
|
process: ie, if it takes 5 minutes, then it is likely that Synapse
|
|
will be unresponsive for 5 minutes during the upgrade.</p>
|
|
<p>If you consider an outage of this duration to be acceptable, no
|
|
further action is necessary and you can simply start Synapse 1.12.0.</p>
|
|
<p>If you would prefer to reduce the downtime, continue with the steps
|
|
below.</p>
|
|
</li>
|
|
<li>
|
|
<p>The easiest workaround for this issue is to manually create a new
|
|
index before upgrading. On PostgreSQL, his can be done as follows:</p>
|
|
<pre><code class="language-sql">CREATE INDEX CONCURRENTLY tmp_upgrade_1_12_0_index
|
|
ON state_events(room_id) WHERE type = 'm.room.create';
|
|
</code></pre>
|
|
<p>The above query may take some time, but is also safe to run while
|
|
Synapse is running.</p>
|
|
<p>We assume that no SQLite users have databases large enough to be
|
|
affected. If you <em>are</em> affected, you can run a similar query,
|
|
omitting the <code>CONCURRENTLY</code> keyword. Note however that this
|
|
operation may in itself cause Synapse to stop running for some time.
|
|
Synapse admins are reminded that <a href="https://github.com/matrix-org/synapse/blob/master/README.rst#using-postgresql">SQLite is not recommended for use
|
|
outside a test
|
|
environment</a>.</p>
|
|
</li>
|
|
<li>
|
|
<p>Once the index has been created, the <code>SELECT</code> query in step 1 above
|
|
should complete quickly. It is therefore safe to upgrade to Synapse
|
|
1.12.0.</p>
|
|
</li>
|
|
<li>
|
|
<p>Once Synapse 1.12.0 has successfully started and is responding to
|
|
HTTP requests, the temporary index can be removed:</p>
|
|
<pre><code class="language-sql">DROP INDEX tmp_upgrade_1_12_0_index;
|
|
</code></pre>
|

<p>In an attempt to configure Synapse in a privacy preserving way, the
|
|
default behaviours of <code>allow_public_rooms_without_auth</code> and
|
|
<code>allow_public_rooms_over_federation</code> have been inverted. This means that
|
|
by default, only authenticated users querying the Client/Server API will
|
|
be able to query the room directory, and relatedly that the server will
|
|
not share room directory information with other servers over federation.</p>
|
|
<p>If your installation does not explicitly set these settings one way or
|
|
the other and you want either setting to be <code>true</code> then it will
|
|
necessary to update your homeserver configuration file accordingly.</p>

|
|
<p>If you have configured a custom template directory with the

<h2 id="3pid-verification-changes"><a class="header" href="#3pid-verification-changes">3pid verification changes</a></h2>
|
|
<p><strong>Note: As of this release, users will be unable to add phone numbers or
|
|
email addresses to their accounts, without changes to the Synapse
|
|
configuration. This includes adding an email address during
|
|
registration.</strong></p>
|
|
<p>It is possible for a user to associate an email address or phone number
|
|
with their account, for a number of reasons:</p>
|
|
<ul>
|
|
<li>for use when logging in, as an alternative to the user id.</li>
|
|
<li>in the case of email, as an alternative contact to help with account
|
|
recovery.</li>
|
|
<li>in the case of email, to receive notifications of missed messages.</li>
|
|
</ul>
|
|
<p>Before an email address or phone number can be added to a user's
|
|
account, or before such an address is used to carry out a
|
|
password-reset, Synapse must confirm the operation with the owner of the
|
|
email address or phone number. It does this by sending an email or text
|
|
giving the user a link or token to confirm receipt. This process is
|
|
known as '3pid verification'. ('3pid', or 'threepid', stands for
|
|
third-party identifier, and we use it to refer to external identifiers
|
|
such as email addresses and phone numbers.)</p>
|
|
<p>Previous versions of Synapse delegated the task of 3pid verification to
|
|
an identity server by default. In most cases this server is <code>vector.im</code>
|
|
or <code>matrix.org</code>.</p>
|
|
<p>In Synapse 1.4.0, for security and privacy reasons, the homeserver will
|
|
no longer delegate this task to an identity server by default. Instead,
|
|
the server administrator will need to explicitly decide how they would
|
|
like the verification messages to be sent.</p>
|
|
<p>In the medium term, the <code>vector.im</code> and <code>matrix.org</code> identity servers
|
|
will disable support for delegated 3pid verification entirely. However,
|
|
in order to ease the transition, they will retain the capability for a
|
|
limited period. Delegated email verification will be disabled on Monday
|
|
2nd December 2019 (giving roughly 2 months notice). Disabling delegated
|
|
SMS verification will follow some time after that once SMS verification
|
|
support lands in Synapse.</p>
|
|
<p>Once delegated 3pid verification support has been disabled in the
|
|
<code>vector.im</code> and <code>matrix.org</code> identity servers, all Synapse versions that
|
|
depend on those instances will be unable to verify email and phone
|
|
numbers through them. There are no imminent plans to remove delegated
|
|
3pid verification from Sydent generally. (Sydent is the identity server
|
|
project that backs the <code>vector.im</code> and <code>matrix.org</code> instances).</p>
|
|
<h3 id="email"><a class="header" href="#email">Email</a></h3>
|
|
<p>Following upgrade, to continue verifying email (e.g. as part of the
|
|
registration process), admins can either:-</p>
|
|
<ul>
|
|
<li>Configure Synapse to use an email server.</li>
|
|
<li>Run or choose an identity server which allows delegated email
|
|
verification and delegate to it.</li>
|
|
</ul>
|
|
<h4 id="configure-smtp-in-synapse"><a class="header" href="#configure-smtp-in-synapse">Configure SMTP in Synapse</a></h4>
|
|
<p>To configure an SMTP server for Synapse, modify the configuration
|
|
section headed <code>email</code>, and be sure to have at least the
|
|
<code>smtp_host, smtp_port</code> and <code>notif_from</code> fields filled out.</p>
|
|
<p>You may also need to set <code>smtp_user</code>, <code>smtp_pass</code>, and
|
|
<code>require_transport_security</code>.</p>
|
|
<p>See the <a href="docs/sample_config.yaml">sample configuration file</a> for more
|
|
details on these settings.</p>
|
|
<h4 id="delegate-email-to-an-identity-server"><a class="header" href="#delegate-email-to-an-identity-server">Delegate email to an identity server</a></h4>
|
|
<p>Some admins will wish to continue using email verification as part of
|
|
the registration process, but will not immediately have an appropriate
|
|
SMTP server at hand.</p>
|
|
<p>To this end, we will continue to support email verification delegation
|
|
via the <code>vector.im</code> and <code>matrix.org</code> identity servers for two months.
|
|
Support for delegated email verification will be disabled on Monday 2nd
|
|
December.</p>
|
|
<p>The <code>account_threepid_delegates</code> dictionary defines whether the
|
|
homeserver should delegate an external server (typically an <a href="https://matrix.org/docs/spec/identity_service/r0.2.1">identity
|
|
server</a>) to handle
|
|
sending confirmation messages via email and SMS.</p>
|
|
<p>So to delegate email verification, in <code>homeserver.yaml</code>, set
|
|
<code>account_threepid_delegates.email</code> to the base URL of an identity
|
|
server. For example:</p>
|
|
<pre><code class="language-yaml">account_threepid_delegates:
|
|
email: https://example.com # Delegate email sending to example.com
|
|
</code></pre>
|
|
<p>Note that <code>account_threepid_delegates.email</code> replaces the deprecated
|
|
<code>email.trust_identity_server_for_password_resets</code>: if
|
|
<code>email.trust_identity_server_for_password_resets</code> is set to <code>true</code>, and
|
|
<code>account_threepid_delegates.email</code> is not set, then the first entry in
|
|
<code>trusted_third_party_id_servers</code> will be used as the
|
|
<code>account_threepid_delegate</code> for email. This is to ensure compatibility
|
|
with existing Synapse installs that set up external server handling for
|
|
these tasks before v1.4.0. If
|
|
<code>email.trust_identity_server_for_password_resets</code> is <code>true</code> and no
|
|
trusted identity server domains are configured, Synapse will report an
|
|
error and refuse to start.</p>
|
|
<p>If <code>email.trust_identity_server_for_password_resets</code> is <code>false</code> or
|
|
absent and no <code>email</code> delegate is configured in
|
|
<code>account_threepid_delegates</code>, then Synapse will send email verification
|
|
messages itself, using the configured SMTP server (see above). that
|
|
type.</p>
|
|
<h3 id="phone-numbers"><a class="header" href="#phone-numbers">Phone numbers</a></h3>
|
|
<p>Synapse does not support phone-number verification itself, so the only
|
|
way to maintain the ability for users to add phone numbers to their
|
|
accounts will be by continuing to delegate phone number verification to
|
|
the <code>matrix.org</code> and <code>vector.im</code> identity servers (or another identity
|
|
server that supports SMS sending).</p>
|
|
<p>The <code>account_threepid_delegates</code> dictionary defines whether the
|
|
homeserver should delegate an external server (typically an <a href="https://matrix.org/docs/spec/identity_service/r0.2.1">identity
|
|
server</a>) to handle
|
|
sending confirmation messages via email and SMS.</p>
|
|
<p>So to delegate phone number verification, in <code>homeserver.yaml</code>, set
|
|
<code>account_threepid_delegates.msisdn</code> to the base URL of an identity
|
|
server. For example:</p>
|
|
<pre><code class="language-yaml">account_threepid_delegates:
|
|
msisdn: https://example.com # Delegate sms sending to example.com
|
|
</code></pre>
|
|
<p>The <code>matrix.org</code> and <code>vector.im</code> identity servers will continue to
|
|
support delegated phone number verification via SMS until such time as
|
|
it is possible for admins to configure their servers to perform phone
|
|
number verification directly. More details will follow in a future
|
|
release.</p>

<h2 id="rolling-back-to-v131"><a class="header" href="#rolling-back-to-v131">Rolling back to v1.3.1</a></h2>
|
|
<p>If you encounter problems with v1.4.0, it should be possible to roll
|
|
back to v1.3.1, subject to the following:</p>
|
|
<ul>
|
|
<li>
|
|
<p>The 'room statistics' engine was heavily reworked in this release
|
|
(see <a href="https://github.com/matrix-org/synapse/pull/5971">#5971</a>),
|
|
including significant changes to the database schema, which are not
|
|
easily reverted. This will cause the room statistics engine to stop
|
|
updating when you downgrade.</p>
|
|
<p>The room statistics are essentially unused in v1.3.1 (in future
|
|
versions of Synapse, they will be used to populate the room
|
|
directory), so there should be no loss of functionality. However,
|
|
the statistics engine will write errors to the logs, which can be
|
|
avoided by setting the following in <code>homeserver.yaml</code>:</p>
|
|
<pre><code class="language-yaml">stats:

|
|
<p>Don't forget to re-enable it when you upgrade again, in preparation

<h2 id="validation-of-tls-certificates"><a class="header" href="#validation-of-tls-certificates">Validation of TLS certificates</a></h2>
|
|
<p>Synapse v1.0 is the first release to enforce validation of TLS

certificates for the federation API. It is therefore essential that your
|
|
certificates are correctly configured. See the
|
|
<a href="../MSC1711_certificates_FAQ.html">FAQ</a> for more information.</p>
|
|
<p>Note, v1.0 installations will also no longer be able to federate with

servers that have not correctly configured their certificates.</p>
|
|
<p>In rare cases, it may be desirable to disable certificate checking: for
|
|
example, it might be essential to be able to federate with a given

<h2 id="email-1"><a class="header" href="#email-1">Email</a></h2>
|
|
<p>When a user requests a password reset, Synapse will send an email to the
|
|
user to confirm the request.</p>
|
|
<p>Previous versions of Synapse delegated the job of sending this email to
|
|
an identity server. If the identity server was somehow malicious or
|
|
became compromised, it would be theoretically possible to hijack an
|
|
account through this means.</p>
|
|
<p>Therefore, by default, Synapse v1.0 will send the confirmation email
|
|
itself. If Synapse is not configured with an SMTP server, password reset
|
|
via email will be disabled.</p>
|
|
<p>To configure an SMTP server for Synapse, modify the configuration
|
|
section headed <code>email</code>, and be sure to have at least the <code>smtp_host</code>,
|
|
<code>smtp_port</code> and <code>notif_from</code> fields filled out. You may also need to set
|
|
<code>smtp_user</code>, <code>smtp_pass</code>, and <code>require_transport_security</code>.</p>
|
|
<p>If you are absolutely certain that you wish to continue using an
|
|
identity server for password resets, set
|
|
<code>trust_identity_server_for_password_resets</code> to <code>true</code>.</p>
|
|
<p>See the <a href="docs/sample_config.yaml">sample configuration file</a> for more
|
|
details on these settings.</p>
|
|
<h2 id="new-email-templates"><a class="header" href="#new-email-templates">New email templates</a></h2>
|
|
<p>Some new templates have been added to the default template directory for the purpose of
|
|
the homeserver sending its own password reset emails. If you have configured a
|
|
custom <code>template_dir</code> in your Synapse config, these files will need to be added.</p>
|
|
<p><code>password_reset.html</code> and <code>password_reset.txt</code> are HTML and plain text
|
|
templates respectively that contain the contents of what will be emailed
|
|
to the user upon attempting to reset their password via email.
|
|
<code>password_reset_success.html</code> and <code>password_reset_failure.html</code> are HTML
|
|
files that the content of which (assuming no redirect URL is set) will
|
|
be shown to the user after they attempt to click the link in the email
|
|
sent to them.</p>

|
|
<p>Please be aware that, before Synapse v1.0 is released around March 2019,
|
|
you will need to replace any self-signed certificates with those
|
|
verified by a root CA. Information on how to do so can be found at <a href="../ACME.html">the
|
|
ACME docs</a>.</p>

<li>
|
|
<p>This release is the first to fully support Python 3. Synapse will
|
|
now run on Python versions 3.5, or 3.6 (as well as 2.7). We
|
|
recommend switching to Python 3, as it has been shown to give
|
|
performance improvements.</p>
|
|
<p>For users who have installed Synapse into a virtualenv, we recommend
|
|
doing this by creating a new virtualenv. For example:</p>
|
|
<pre><code>virtualenv -p python3 ~/synapse/env3
|
|
source ~/synapse/env3/bin/activate
|
|
pip install matrix-synapse
|
|
</code></pre>
|
|
<p>You can then start synapse as normal, having activated the new
|
|
virtualenv:</p>
|
|
<pre><code>cd ~/synapse
|
|
source env3/bin/activate
|
|
synctl start
|
|
</code></pre>
|
|
<p>Users who have installed from distribution packages should see the
|
|
relevant package documentation. See below for notes on Debian
|
|
packages.</p>
|
|
<ul>
|
|
<li>
|
|
<p>When upgrading to Python 3, you <strong>must</strong> make sure that your log
|
|
files are configured as UTF-8, by adding <code>encoding: utf8</code> to the
|
|
<code>RotatingFileHandler</code> configuration (if you have one) in your
|
|
<code><server>.log.config</code> file. For example, if your <code>log.config</code>
|
|
file contains:</p>
|
|
<pre><code>handlers:
|
|
file:
|
|
class: logging.handlers.RotatingFileHandler
|
|
formatter: precise
|
|
filename: homeserver.log
|
|
maxBytes: 104857600
|
|
backupCount: 10
|
|
filters: [context]
|
|
console:
|
|
class: logging.StreamHandler
|
|
formatter: precise
|
|
filters: [context]
|
|
</code></pre>
|
|
<p>Then you should update this to be:</p>
|
|
<pre><code>handlers:
|
|
file:
|
|
class: logging.handlers.RotatingFileHandler
|
|
formatter: precise
|
|
filename: homeserver.log
|
|
maxBytes: 104857600
|
|
backupCount: 10
|
|
filters: [context]
|
|
encoding: utf8
|
|
console:
|
|
class: logging.StreamHandler
|
|
formatter: precise
|
|
filters: [context]
|
|
</code></pre>
|
|
<p>There is no need to revert this change if downgrading to
|
|
Python 2.</p>
|
|
</li>
|
|
</ul>
|
|
<p>We are also making available Debian packages which will run Synapse
|
|
on Python 3. You can switch to these packages with
|
|
<code>apt-get install matrix-synapse-py3</code>, however, please read
|
|
<a href="https://github.com/matrix-org/synapse/blob/release-v0.34.0/debian/NEWS">debian/NEWS</a>
|
|
before doing so. The existing <code>matrix-synapse</code> packages will
|
|
continue to use Python 2 for the time being.</p>
|
|
</li>
|
|
<li>
|
|
<p>This release removes the <code>riot.im</code> from the default list of trusted
|
|
identity servers.</p>
|
|
<p>If <code>riot.im</code> is in your homeserver's list of
|
|
<code>trusted_third_party_id_servers</code>, you should remove it. It was added
|
|
in case a hypothetical future identity server was put there. If you
|
|
don't remove it, users may be unable to deactivate their accounts.</p>
|
|
</li>
|
|
<li>
|
|
<p>This release no longer installs the (unmaintained) Matrix Console
|
|
web client as part of the default installation. It is possible to
|
|
re-enable it by installing it separately and setting the
|
|
<code>web_client_location</code> config option, but please consider switching
|
|
to another client.</p>
|
|
</li>

|
</ol>

<h1 id="upgrading-to-v0337"><a class="header" href="#upgrading-to-v0337">Upgrading to v0.33.7</a></h1>
|
|
<p>This release removes the example email notification templates from
|
|
<code>res/templates</code> (they are now internal to the python package). This
|
|
should only affect you if you (a) deploy your Synapse instance from a
|
|
git checkout or a github snapshot URL, and (b) have email notifications
|
|
enabled.</p>
|
|
<p>If you have email notifications enabled, you should ensure that
|
|
<code>email.template_dir</code> is either configured to point at a directory where
|
|
you have installed customised templates, or leave it unset to use the
|
|
default templates.</p>
|
|
<h1 id="upgrading-to-v0273"><a class="header" href="#upgrading-to-v0273">Upgrading to v0.27.3</a></h1>
|
|
<p>This release expands the anonymous usage stats sent if the opt-in
|
|
<code>report_stats</code> configuration is set to <code>true</code>. We now capture RSS memory
|
|
and cpu use at a very coarse level. This requires administrators to
|
|
install the optional <code>psutil</code> python module.</p>
|
|
<p>We would appreciate it if you could assist by ensuring this module is
|
|
available and <code>report_stats</code> is enabled. This will let us see if
|
|
performance changes to synapse are having an impact to the general
|
|
community.</p>
|
|
<h1 id="upgrading-to-v0150"><a class="header" href="#upgrading-to-v0150">Upgrading to v0.15.0</a></h1>
|
|
<p>If you want to use the new URL previewing API
|
|
(<code>/_matrix/media/r0/preview_url</code>) then you have to explicitly enable it
|
|
in the config and update your dependencies dependencies. See README.rst
|
|
for details.</p>
|
|
<h1 id="upgrading-to-v0110"><a class="header" href="#upgrading-to-v0110">Upgrading to v0.11.0</a></h1>
|
|
<p>This release includes the option to send anonymous usage stats to
|
|
matrix.org, and requires that administrators explictly opt in or out by
|
|
setting the <code>report_stats</code> option to either <code>true</code> or <code>false</code>.</p>
|
|
<p>We would really appreciate it if you could help our project out by
|
|
reporting anonymized usage statistics from your homeserver. Only very
|
|
basic aggregate data (e.g. number of users) will be reported, but it
|
|
helps us to track the growth of the Matrix community, and helps us to
|
|
make Matrix a success, as well as to convince other networks that they
|
|
should peer with us.</p>
|
|
<h1 id="upgrading-to-v090"><a class="header" href="#upgrading-to-v090">Upgrading to v0.9.0</a></h1>
|
|
<p>Application services have had a breaking API change in this version.</p>
|
|
<p>They can no longer register themselves with a home server using the AS
|
|
HTTP API. This decision was made because a compromised application
|
|
service with free reign to register any regex in effect grants full
|
|
read/write access to the home server if a regex of <code>.*</code> is used. An
|
|
attack where a compromised AS re-registers itself with <code>.*</code> was deemed
|
|
too big of a security risk to ignore, and so the ability to register
|
|
with the HS remotely has been removed.</p>
|
|
<p>It has been replaced by specifying a list of application service
|
|
registrations in <code>homeserver.yaml</code>:</p>
|
|
<pre><code>app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
|
|
</code></pre>
|
|
<p>Where <code>registration-01.yaml</code> looks like:</p>
|
|
<pre><code>url: <String> # e.g. "https://my.application.service.com"
|
|
as_token: <String>
|
|
hs_token: <String>
|
|
sender_localpart: <String> # This is a new field which denotes the user_id localpart when using the AS token
|
|
namespaces:
|
|
users:
|
|
- exclusive: <Boolean>
|
|
regex: <String> # e.g. "@prefix_.*"
|
|
aliases:
|
|
- exclusive: <Boolean>
|
|
regex: <String>
|
|
rooms:
|
|
- exclusive: <Boolean>
|
|
regex: <String>
|
|
</code></pre>
|
|
<h1 id="upgrading-to-v080"><a class="header" href="#upgrading-to-v080">Upgrading to v0.8.0</a></h1>
|
|
<p>Servers which use captchas will need to add their public key to:</p>
|
|
<pre><code>static/client/register/register_config.js
|
|
|
|
window.matrixRegistrationConfig = {
|
|
recaptcha_public_key: "YOUR_PUBLIC_KEY"
|
|
};
|
|
</code></pre>
|
|
<p>This is required in order to support registration fallback (typically
|
|
used on mobile devices).</p>
|
|
<h1 id="upgrading-to-v070"><a class="header" href="#upgrading-to-v070">Upgrading to v0.7.0</a></h1>
|
|
<p>New dependencies are:</p>
|
|
<ul>
|
|
<li>pydenticon</li>
|
|
<li>simplejson</li>
|
|
<li>syutil</li>
|
|
<li>matrix-angular-sdk</li>
|
|
</ul>
|
|
<p>To pull in these dependencies in a virtual env, run:</p>
|
|
<pre><code>python synapse/python_dependencies.py | xargs -n 1 pip install
|
|
</code></pre>
|
|
<h1 id="upgrading-to-v060"><a class="header" href="#upgrading-to-v060">Upgrading to v0.6.0</a></h1>
|
|
<p>To pull in new dependencies, run:</p>
|
|
<pre><code>python setup.py develop --user
|
|
</code></pre>
|
|
<p>This update includes a change to the database schema. To upgrade you
|
|
first need to upgrade the database by running:</p>
|
|
<pre><code>python scripts/upgrade_db_to_v0.6.0.py <db> <server_name> <signing_key>
|
|
</code></pre>
|
|
<p>Where [<db>]{.title-ref} is the location of the database,
|
|
[<server_name>]{.title-ref} is the server name as specified in the
|
|
synapse configuration, and [<signing_key>]{.title-ref} is the location
|
|
of the signing key as specified in the synapse configuration.</p>
|
|
<p>This may take some time to complete. Failures of signatures and content
|
|
hashes can safely be ignored.</p>
|
|
<h1 id="upgrading-to-v051"><a class="header" href="#upgrading-to-v051">Upgrading to v0.5.1</a></h1>
|
|
<p>Depending on precisely when you installed v0.5.0 you may have ended up
|
|
with a stale release of the reference matrix webclient installed as a
|
|
python module. To uninstall it and ensure you are depending on the
|
|
latest module, please run:</p>
|
|
<pre><code>$ pip uninstall syweb
|
|
</code></pre>
|
|
<h1 id="upgrading-to-v050"><a class="header" href="#upgrading-to-v050">Upgrading to v0.5.0</a></h1>
|
|
<p>The webclient has been split out into a seperate repository/pacakage in
|
|
this release. Before you restart your homeserver you will need to pull
|
|
in the webclient package by running:</p>
|
|
<pre><code>python setup.py develop --user
|
|
</code></pre>
|
|
<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-0.5.0.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>If you would like to keep your history, please take a copy of your
|
|
database file and ask for help in #matrix:matrix.org. The upgrade
|
|
process is, unfortunately, non trivial and requires human intervention
|
|
to resolve any resulting conflicts during the upgrade process.</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-0.5.0.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>
|
|
<h1 id="upgrading-to-v040"><a class="header" href="#upgrading-to-v040">Upgrading to v0.4.0</a></h1>
|
|
<p>This release needs an updated syutil version. Run:</p>
|
|
<pre><code>python setup.py develop
|
|
</code></pre>
|
|
<p>You will also need to upgrade your configuration as the signing key
|
|
format has changed. Run:</p>
|
|
<pre><code>python -m synapse.app.homeserver --config-path <CONFIG> --generate-config
|
|
</code></pre>
|
|
<h1 id="upgrading-to-v030"><a class="header" href="#upgrading-to-v030">Upgrading to v0.3.0</a></h1>
|
|
<p>This registration API now closely matches the login API. 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
