Before upgrading check if any special steps are required to upgrade from the what you currently have installed to current version of synapse. The extra instructions that may be required are listed later in this document.
If synapse was installed in a virtualenv then activate that virtualenv before upgrading. If synapse is installed in a virtualenv in
~/synapse/envthen run:source ~/synapse/env/bin/activate
If synapse was installed using pip then upgrade to the latest version by running:
pip install --upgrade matrix-synapse[all] # restart synapse synctl restartIf synapse was installed using git then upgrade to the latest version by running:
# Pull the latest version of the master branch. git pull # Update synapse and its python dependencies. pip install --upgrade .[all] # restart synapse ./synctl restart
To check whether your update was successful, you can check the Server header returned by the Client-Server API:
# replace <host.name> with the hostname of your synapse homeserver.
# You may need to specify a port (eg, :8448) if your server is not
# configured on port 443.
curl -kv https://<host.name>/_matrix/client/versions 2>&1 | grep "Server:"Some counter metrics have been renamed, with the old names deprecated. See the metrics documentation for details.
Synapse v1.1.0 removes support for older Python and PostgreSQL versions, as outlined in our deprecation notice.
Synapse v1.1.0 has a minimum Python requirement of Python 3.5. Python 3.6 or Python 3.7 are recommended as they have improved internal string handling, significantly reducing memory usage.
If you use current versions of the Matrix.org-distributed Debian packages or Docker images, action is not required.
If you install Synapse in a Python virtual environment, please see "Upgrading to v0.34.0" for notes on setting up a new virtualenv under Python 3.
If using PostgreSQL under Synapse, you will need to use PostgreSQL 9.5 or above. Please see the PostgreSQL documentation for more details on upgrading your database.
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 FAQ for more information.
Note, v1.0 installations will also no longer be able to federate with servers that have not correctly configured their certificates.
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 legacy server in a closed federation. This can be done in one of two ways:-
- Configure the global switch
federation_verify_certificatestofalse. - Configure a whitelist of server domains to trust via
federation_certificate_verification_whitelist.
See the sample configuration file for more details on these settings.
When a user requests a password reset, Synapse will send an email to the user to confirm the request.
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.
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.
To configure an SMTP server for Synapse, modify the configuration section
headed email, and be sure to have at least the smtp_host, smtp_port
and notif_from fields filled out. You may also need to set smtp_user,
smtp_pass, and require_transport_security.
If you are absolutely certain that you wish to continue using an identity
server for password resets, set trust_identity_server_for_password_resets to true.
See the sample configuration file for more details on these settings.
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 the ACME docs.
For more information on configuring TLS certificates see the FAQ.
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.
For users who have installed Synapse into a virtualenv, we recommend doing this by creating a new virtualenv. For example:
virtualenv -p python3 ~/synapse/env3 source ~/synapse/env3/bin/activate pip install matrix-synapse
You can then start synapse as normal, having activated the new virtualenv:
cd ~/synapse source env3/bin/activate synctl start
Users who have installed from distribution packages should see the relevant package documentation. See below for notes on Debian packages.
When upgrading to Python 3, you must make sure that your log files are configured as UTF-8, by adding
encoding: utf8to theRotatingFileHandlerconfiguration (if you have one) in your<server>.log.configfile. For example, if yourlog.configfile contains: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]Then you should update this to be:
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]There is no need to revert this change if downgrading to Python 2.
We are also making available Debian packages which will run Synapse on Python 3. You can switch to these packages with
apt-get install matrix-synapse-py3, however, please read debian/NEWS before doing so. The existingmatrix-synapsepackages will continue to use Python 2 for the time being.This release removes the
riot.imfrom the default list of trusted identity servers.If
riot.imis in your homeserver's list oftrusted_third_party_id_servers, 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.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
web_client_locationconfig option, but please consider switching to another client.
This release removes the example email notification templates from
res/templates (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.
If you have email notifications enabled, you should ensure that
email.template_dir is either configured to point at a directory where you
have installed customised templates, or leave it unset to use the default
templates.
This release expands the anonymous usage stats sent if the opt-in
report_stats configuration is set to true. We now capture RSS memory
and cpu use at a very coarse level. This requires administrators to install
the optional psutil python module.
We would appreciate it if you could assist by ensuring this module is available
and report_stats is enabled. This will let us see if performance changes to
synapse are having an impact to the general community.
If you want to use the new URL previewing API (/_matrix/media/r0/preview_url) then you have to explicitly enable it in the config and update your dependencies dependencies. See README.rst for details.
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
report_stats option to either true or false.
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.
Application services have had a breaking API change in this version.
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 .*
is used. An attack where a compromised AS re-registers itself with .* was deemed too
big of a security risk to ignore, and so the ability to register with the HS remotely has
been removed.
It has been replaced by specifying a list of application service registrations in
homeserver.yaml:
app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
Where registration-01.yaml looks like:
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>
Servers which use captchas will need to add their public key to:
static/client/register/register_config.js
window.matrixRegistrationConfig = {
recaptcha_public_key: "YOUR_PUBLIC_KEY"
};
This is required in order to support registration fallback (typically used on mobile devices).
New dependencies are:
- pydenticon
- simplejson
- syutil
- matrix-angular-sdk
To pull in these dependencies in a virtual env, run:
python synapse/python_dependencies.py | xargs -n 1 pip install
To pull in new dependencies, run:
python setup.py develop --user
This update includes a change to the database schema. To upgrade you first need to upgrade the database by running:
python scripts/upgrade_db_to_v0.6.0.py <db> <server_name> <signing_key>
Where <db> is the location of the database, <server_name> is the server name as specified in the synapse configuration, and <signing_key> is the location of the signing key as specified in the synapse configuration.
This may take some time to complete. Failures of signatures and content hashes can safely be ignored.
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:
$ pip uninstall syweb
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:
python setup.py develop --user
This release completely changes the database schema and so requires upgrading it before starting the new version of the homeserver.
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.
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.
Before running the command the homeserver should be first completely shutdown. To run it, simply specify the location of the database, e.g.:
./scripts/database-prepare-for-0.5.0.sh "homeserver.db"
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.
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.
This release needs an updated syutil version. Run:
python setup.py develop
You will also need to upgrade your configuration as the signing key format has changed. Run:
python -m synapse.app.homeserver --config-path <CONFIG> --generate-config
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:
{
type: m.login.password,
user: foo,
password: bar
}
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: m.login.recaptcha which must be completed before you can transition
to the next stage. There is a new login type: m.login.email.identity which
contains the threepidCreds key which were previously sent in the original
register request. For more information on this, see the specification.
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.
The home server now requires setting up of SSL config before it can run. To automatically generate default config use:
$ python synapse/app/homeserver.py \
--server-name machine.my.domain.name \
--bind-port 8448 \
--config-path homeserver.config \
--generate-config
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:
$ python synapse/app/homeserver.py --config-path homeserver.config
See the README.rst for more information.
Also note that some config options have been renamed, including:
- "host" to "server-name"
- "database" to "database-path"
- "port" to "bind-port" and "unsecure-port"
This release completely changes the database schema and so requires upgrading it before starting the new version of the homeserver.
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.
Before running the command the homeserver should be first completely shutdown. To run it, simply specify the location of the database, e.g.:
./scripts/database-prepare-for-0.0.1.sh "homeserver.db"
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.
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.
