# Upgrading Synapse
|
|
|
|
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.
|
|
|
|
- Check that your versions of Python and PostgreSQL are still
|
|
supported.
|
|
|
|
Synapse follows upstream lifecycles for [Python](https://endoflife.date/python) and
|
|
[PostgreSQL](https://endoflife.date/postgresql), and removes support for versions
|
|
which are no longer maintained.
|
|
|
|
The website <https://endoflife.date> also offers convenient
|
|
summaries.
|
|
|
|
- If Synapse was installed using [prebuilt
|
|
packages](setup/installation.md#prebuilt-packages), you will need to follow the
|
|
normal process for upgrading those packages.
|
|
|
|
- If Synapse was installed using pip then upgrade to the latest
|
|
version by running:
|
|
|
|
```bash
|
|
pip install --upgrade matrix-synapse
|
|
```
|
|
|
|
- If Synapse was installed from source, then:
|
|
|
|
1. Obtain the latest version of the source code. Git users can run
|
|
`git pull` to do this.
|
|
|
|
2. If you're running Synapse in a virtualenv, make sure to activate it before
|
|
upgrading. For example, if Synapse is installed in a virtualenv in `~/synapse/env` then
|
|
run:
|
|
|
|
```bash
|
|
source ~/synapse/env/bin/activate
|
|
pip install --upgrade .
|
|
```
|
|
Include any relevant extras between square brackets, e.g. `pip install --upgrade ".[postgres,oidc]"`.
|
|
|
|
3. If you're using `poetry` to manage a Synapse installation, run:
|
|
```bash
|
|
poetry install
|
|
```
|
|
Include any relevant extras with `--extras`, e.g. `poetry install --extras postgres --extras oidc`.
|
|
It's probably easiest to run `poetry install --extras all`.
|
|
|
|
4. Restart Synapse:
|
|
|
|
```bash
|
|
synctl restart
|
|
```
|
|
|
|
To check whether your update was successful, you can check the running
|
|
server version with:
|
|
|
|
```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
|
|
```
|
|
|
|
## Rolling back to older versions
|
|
|
|
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.
|
|
|
|
In general, you will need to undo any changes made during the upgrade
|
|
process, for example:
|
|
|
|
- pip:
|
|
|
|
```bash
|
|
source env/bin/activate
|
|
# replace `1.3.0` accordingly:
|
|
pip install matrix-synapse==1.3.0
|
|
```
|
|
|
|
- Debian:
|
|
|
|
```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
|
|
```
|
|
|
|
# Upgrading to v1.58.0
|
|
|
|
## Groups/communities feature has been disabled by default
|
|
|
|
The non-standard groups/communities feature in Synapse has been disabled by default
|
|
and will be removed in Synapse v1.61.0.
|
|
|
|
# Upgrading to v1.57.0
|
|
|
|
## Changes to database schema for application services
|
|
|
|
Synapse v1.57.0 includes a [change](https://github.com/matrix-org/synapse/pull/12209) to the
|
|
way transaction IDs are managed for application services. If your deployment uses a dedicated
|
|
worker for application service traffic, **it must be stopped** when the database is upgraded
|
|
(which normally happens when the main process is upgraded), to ensure the change is made safely
|
|
without any risk of reusing transaction IDs.
|
|
|
|
Deployments which do not use separate worker processes can be upgraded as normal. Similarly,
|
|
deployments where no application services are in use can be upgraded as normal.
|
|
|
|
<details>
|
|
<summary><b>Recovering from an incorrect upgrade</b></summary>
|
|
|
|
If the database schema is upgraded *without* stopping the worker responsible
|
|
for AS traffic, then the following error may be given when attempting to start
|
|
a Synapse worker or master process:
|
|
|
|
```
|
|
**********************************************************************************
|
|
Error during initialisation:
|
|
|
|
Postgres sequence 'application_services_txn_id_seq' is inconsistent with associated
|
|
table 'application_services_txns'. This can happen if Synapse has been downgraded and
|
|
then upgraded again, or due to a bad migration.
|
|
|
|
To fix this error, shut down Synapse (including any and all workers)
|
|
and run the following SQL:
|
|
|
|
SELECT setval('application_services_txn_id_seq', (
|
|
SELECT GREATEST(MAX(txn_id), 0) FROM application_services_txns
|
|
));
|
|
|
|
See docs/postgres.md for more information.
|
|
|
|
There may be more information in the logs.
|
|
**********************************************************************************
|
|
```
|
|
|
|
This error may also be seen if Synapse is *downgraded* to an earlier version,
|
|
and then upgraded again to v1.57.0 or later.
|
|
|
|
In either case:
|
|
|
|
1. Ensure that the worker responsible for AS traffic is stopped.
|
|
2. Run the SQL command given in the error message via `psql`.
|
|
|
|
Synapse should then start correctly.
|
|
</details>
|
|
|
|
# Upgrading to v1.56.0
|
|
|
|
## Open registration without verification is now disabled by default
|
|
|
|
Synapse will refuse to start if registration is enabled without email, captcha, or token-based verification unless the new config
|
|
flag `enable_registration_without_verification` is set to "true".
|
|
|
|
## Groups/communities feature has been deprecated
|
|
|
|
The non-standard groups/communities feature in Synapse has been deprecated and will
|
|
be disabled by default in Synapse v1.58.0.
|
|
|
|
You can test disabling it by adding the following to your homeserver configuration:
|
|
|
|
```yaml
|
|
experimental_features:
|
|
groups_enabled: false
|
|
```
|
|
|
|
## Change in behaviour for PostgreSQL databases with unsafe locale
|
|
|
|
Synapse now refuses to start when using PostgreSQL with non-`C` values for `COLLATE` and
|
|
`CTYPE` unless the config flag `allow_unsafe_locale`, found in the database section of
|
|
the configuration file, is set to `true`. See the [PostgreSQL documentation](https://matrix-org.github.io/synapse/latest/postgres.html#fixing-incorrect-collate-or-ctype)
|
|
for more information and instructions on how to fix a database with incorrect values.
|
|
|
|
# Upgrading to v1.55.0
|
|
|
|
## `synctl` script has been moved
|
|
|
|
The `synctl` script
|
|
[has been made](https://github.com/matrix-org/synapse/pull/12140) an
|
|
[entry point](https://packaging.python.org/en/latest/specifications/entry-points/)
|
|
and no longer exists at the root of Synapse's source tree. If you wish to use
|
|
`synctl` to manage your homeserver, you should invoke `synctl` directly, e.g.
|
|
`synctl start` instead of `./synctl start` or `/path/to/synctl start`.
|
|
|
|
You will need to ensure `synctl` is on your `PATH`.
|
|
- This is automatically the case when using
|
|
[Debian packages](https://packages.matrix.org/debian/) or
|
|
[docker images](https://hub.docker.com/r/matrixdotorg/synapse)
|
|
provided by Matrix.org.
|
|
- When installing from a wheel, sdist, or PyPI, a `synctl` executable is added
|
|
to your Python installation's `bin`. This should be on your `PATH`
|
|
automatically, though you might need to activate a virtual environment
|
|
depending on how you installed Synapse.
|
|
|
|
|
|
## Compatibility dropped for Mjolnir 1.3.1 and earlier
|
|
|
|
Synapse v1.55.0 drops support for Mjolnir 1.3.1 and earlier.
|
|
If you use the Mjolnir module to moderate your homeserver,
|
|
please upgrade Mjolnir to version 1.3.2 or later before upgrading Synapse.
|
|
|
|
|
|
# Upgrading to v1.54.0
|
|
|
|
## Legacy structured logging configuration removal
|
|
|
|
This release removes support for the `structured: true` logging configuration
|
|
which was deprecated in Synapse v1.23.0. If your logging configuration contains
|
|
`structured: true` then it should be modified based on the
|
|
[structured logging documentation](https://matrix-org.github.io/synapse/v1.56/structured_logging.html#upgrading-from-legacy-structured-logging-configuration).
|
|
|
|
# Upgrading to v1.53.0
|
|
|
|
## Dropping support for `webclient` listeners and non-HTTP(S) `web_client_location`
|
|
|
|
Per the deprecation notice in Synapse v1.51.0, listeners of type `webclient`
|
|
are no longer supported and configuring them is a now a configuration error.
|
|
|
|
Configuring a non-HTTP(S) `web_client_location` configuration is is now a
|
|
configuration error. Since the `webclient` listener is no longer supported, this
|
|
setting only applies to the root path `/` of Synapse's web server and no longer
|
|
the `/_matrix/client/` path.
|
|
|
|
## Stablisation of MSC3231
|
|
|
|
The unstable validity-check endpoint for the
|
|
[Registration Tokens](https://spec.matrix.org/v1.2/client-server-api/#get_matrixclientv1registermloginregistration_tokenvalidity)
|
|
feature has been stabilised and moved from:
|
|
|
|
`/_matrix/client/unstable/org.matrix.msc3231/register/org.matrix.msc3231.login.registration_token/validity`
|
|
|
|
to:
|
|
|
|
`/_matrix/client/v1/register/m.login.registration_token/validity`
|
|
|
|
Please update any relevant reverse proxy or firewall configurations appropriately.
|
|
|
|
## Time-based cache expiry is now enabled by default
|
|
|
|
Formerly, entries in the cache were not evicted regardless of whether they were accessed after storing.
|
|
This behavior has now changed. By default entries in the cache are now evicted after 30m of not being accessed.
|
|
To change the default behavior, go to the `caches` section of the config and change the `expire_caches` and
|
|
`cache_entry_ttl` flags as necessary. Please note that these flags replace the `expiry_time` flag in the config.
|
|
The `expiry_time` flag will still continue to work, but it has been deprecated and will be removed in the future.
|
|
|
|
## Deprecation of `capability` `org.matrix.msc3283.*`
|
|
|
|
The `capabilities` of MSC3283 from the REST API `/_matrix/client/r0/capabilities`
|
|
becomes stable.
|
|
|
|
The old `capabilities`
|
|
- `org.matrix.msc3283.set_displayname`,
|
|
- `org.matrix.msc3283.set_avatar_url` and
|
|
- `org.matrix.msc3283.3pid_changes`
|
|
|
|
are deprecated and scheduled to be removed in Synapse v1.54.0.
|
|
|
|
The new `capabilities`
|
|
- `m.set_displayname`,
|
|
- `m.set_avatar_url` and
|
|
- `m.3pid_changes`
|
|
|
|
are now active by default.
|
|
|
|
## Removal of `user_may_create_room_with_invites`
|
|
|
|
As announced with the release of [Synapse 1.47.0](#deprecation-of-the-user_may_create_room_with_invites-module-callback),
|
|
the deprecated `user_may_create_room_with_invites` module callback has been removed.
|
|
|
|
Modules relying on it can instead implement [`user_may_invite`](https://matrix-org.github.io/synapse/latest/modules/spam_checker_callbacks.html#user_may_invite)
|
|
and use the [`get_room_state`](https://github.com/matrix-org/synapse/blob/872f23b95fa980a61b0866c1475e84491991fa20/synapse/module_api/__init__.py#L869-L876)
|
|
module API to infer whether the invite is happening while creating a room (see [this function](https://github.com/matrix-org/synapse-domain-rule-checker/blob/e7d092dd9f2a7f844928771dbfd9fd24c2332e48/synapse_domain_rule_checker/__init__.py#L56-L89)
|
|
as an example). Alternately, modules can also implement [`on_create_room`](https://matrix-org.github.io/synapse/latest/modules/third_party_rules_callbacks.html#on_create_room).
|
|
|
|
|
|
# Upgrading to v1.52.0
|
|
|
|
## Twisted security release
|
|
|
|
Note that [Twisted 22.1.0](https://github.com/twisted/twisted/releases/tag/twisted-22.1.0)
|
|
has recently been released, which fixes a [security issue](https://github.com/twisted/twisted/security/advisories/GHSA-92x2-jw7w-xvvx)
|
|
within the Twisted library. We do not believe Synapse is affected by this vulnerability,
|
|
though we advise server administrators who installed Synapse via pip to upgrade Twisted
|
|
with `pip install --upgrade Twisted treq` as a matter of good practice. The Docker image
|
|
`matrixdotorg/synapse` and the Debian packages from `packages.matrix.org` are using the
|
|
updated library.
|
|
|
|
# Upgrading to v1.51.0
|
|
|
|
## Deprecation of `webclient` listeners and non-HTTP(S) `web_client_location`
|
|
|
|
Listeners of type `webclient` are deprecated and scheduled to be removed in
|
|
Synapse v1.53.0.
|
|
|
|
Similarly, a non-HTTP(S) `web_client_location` configuration is deprecated and
|
|
will become a configuration error in Synapse v1.53.0.
|
|
|
|
|
|
# Upgrading to v1.50.0
|
|
|
|
## Dropping support for old Python and Postgres versions
|
|
|
|
In line with our [deprecation policy](deprecation_policy.md),
|
|
we've dropped support for Python 3.6 and PostgreSQL 9.6, as they are no
|
|
longer supported upstream.
|
|
|
|
This release of Synapse requires Python 3.7+ and PostgreSQL 10+.
|
|
|
|
|
|
# Upgrading to v1.47.0
|
|
|
|
## Removal of old Room Admin API
|
|
|
|
The following admin APIs were deprecated in [Synapse 1.34](https://github.com/matrix-org/synapse/blob/v1.34.0/CHANGES.md#deprecations-and-removals)
|
|
(released on 2021-05-17) and have now been removed:
|
|
|
|
- `POST /_synapse/admin/v1/<room_id>/delete`
|
|
|
|
Any scripts still using the above APIs should be converted to use the
|
|
[Delete Room API](https://matrix-org.github.io/synapse/latest/admin_api/rooms.html#delete-room-api).
|
|
|
|
## Deprecation of the `user_may_create_room_with_invites` module callback
|
|
|
|
The `user_may_create_room_with_invites` is deprecated and will be removed in a future
|
|
version of Synapse. Modules implementing this callback can instead implement
|
|
[`user_may_invite`](https://matrix-org.github.io/synapse/latest/modules/spam_checker_callbacks.html#user_may_invite)
|
|
and use the [`get_room_state`](https://github.com/matrix-org/synapse/blob/872f23b95fa980a61b0866c1475e84491991fa20/synapse/module_api/__init__.py#L869-L876)
|
|
module API method to infer whether the invite is happening in the context of creating a
|
|
room.
|
|
|
|
We plan to remove this callback in January 2022.
|
|
|
|
# Upgrading to v1.45.0
|
|
|
|
## Changes required to media storage provider modules when reading from the Synapse configuration object
|
|
|
|
Media storage provider modules that read from the Synapse configuration object (i.e. that
|
|
read the value of `hs.config.[...]`) now need to specify the configuration section they're
|
|
reading from. This means that if a module reads the value of e.g. `hs.config.media_store_path`,
|
|
it needs to replace it with `hs.config.media.media_store_path`.
|
|
|
|
# Upgrading to v1.44.0
|
|
|
|
## The URL preview cache is no longer mirrored to storage providers
|
|
The `url_cache/` and `url_cache_thumbnails/` directories in the media store are
|
|
no longer mirrored to storage providers. These two directories can be safely
|
|
deleted from any configured storage providers to reclaim space.
|
|
|
|
# Upgrading to v1.43.0
|
|
|
|
## The spaces summary APIs can now be handled by workers
|
|
|
|
The [available worker applications documentation](https://matrix-org.github.io/synapse/latest/workers.html#available-worker-applications)
|
|
has been updated to reflect that calls to the `/spaces`, `/hierarchy`, and
|
|
`/summary` endpoints can now be routed to workers for both client API and
|
|
federation requests.
|
|
|
|
# Upgrading to v1.42.0
|
|
|
|
## Removal of old Room Admin API
|
|
|
|
The following admin APIs were deprecated in [Synapse 1.25](https://github.com/matrix-org/synapse/blob/v1.25.0/CHANGES.md#removal-warning)
|
|
(released on 2021-01-13) and have now been removed:
|
|
|
|
- `POST /_synapse/admin/v1/purge_room`
|
|
- `POST /_synapse/admin/v1/shutdown_room/<room_id>`
|
|
|
|
Any scripts still using the above APIs should be converted to use the
|
|
[Delete Room API](https://matrix-org.github.io/synapse/latest/admin_api/rooms.html#delete-room-api).
|
|
|
|
## User-interactive authentication fallback templates can now display errors
|
|
|
|
This may affect you if you make use of custom HTML templates for the
|
|
[reCAPTCHA](../synapse/res/templates/recaptcha.html) or
|
|
[terms](../synapse/res/templates/terms.html) fallback pages.
|
|
|
|
The template is now provided an `error` variable if the authentication
|
|
process failed. See the default templates linked above for an example.
|
|
|
|
## Removal of out-of-date email pushers
|
|
|
|
Users will stop receiving message updates via email for addresses that were
|
|
once, but not still, linked to their account.
|
|
|
|
# Upgrading to v1.41.0
|
|
|
|
## Add support for routing outbound HTTP requests via a proxy for federation
|
|
|
|
Since Synapse 1.6.0 (2019-11-26) you can set a proxy for outbound HTTP requests via
|
|
http_proxy/https_proxy environment variables. This proxy was set for:
|
|
- push
|
|
- url previews
|
|
- phone-home stats
|
|
- recaptcha validation
|
|
- CAS auth validation
|
|
- OpenID Connect
|
|
- Federation (checking public key revocation)
|
|
|
|
In this version we have added support for outbound requests for:
|
|
- Outbound federation
|
|
- Downloading remote media
|
|
- Fetching public keys of other servers
|
|
|
|
These requests use the same proxy configuration. If you have a proxy configuration we
|
|
recommend to verify the configuration. It may be necessary to adjust the `no_proxy`
|
|
environment variable.
|
|
|
|
See [using a forward proxy with Synapse documentation](setup/forward_proxy.md) for
|
|
details.
|
|
|
|
## Deprecation of `template_dir`
|
|
|
|
The `template_dir` settings in the `sso`, `account_validity` and `email` sections of the
|
|
configuration file are now deprecated. Server admins should use the new
|
|
`templates.custom_template_directory` setting in the configuration file and use one single
|
|
custom template directory for all aforementioned features. Template file names remain
|
|
unchanged. See [the related documentation](https://matrix-org.github.io/synapse/latest/templates.html)
|
|
for more information and examples.
|
|
|
|
We plan to remove support for these settings in October 2021.
|
|
|
|
## `/_synapse/admin/v1/users/{userId}/media` must be handled by media workers
|
|
|
|
The [media repository worker documentation](https://matrix-org.github.io/synapse/latest/workers.html#synapseappmedia_repository)
|
|
has been updated to reflect that calls to `/_synapse/admin/v1/users/{userId}/media`
|
|
must now be handled by media repository workers. This is due to the new `DELETE` method
|
|
of this endpoint modifying the media store.
|
|
|
|
# Upgrading to v1.39.0
|
|
|
|
## Deprecation of the current third-party rules module interface
|
|
|
|
The current third-party rules module interface is deprecated in favour of the new generic
|
|
modules system introduced in Synapse v1.37.0. Authors of third-party rules modules can refer
|
|
to [this documentation](modules/porting_legacy_module.md)
|
|
to update their modules. Synapse administrators can refer to [this documentation](modules/index.md)
|
|
to update their configuration once the modules they are using have been updated.
|
|
|
|
We plan to remove support for the current third-party rules interface in September 2021.
|
|
|
|
|
|
# Upgrading to v1.38.0
|
|
|
|
## Re-indexing of `events` table on Postgres databases
|
|
|
|
This release includes a database schema update which requires re-indexing one of
|
|
the larger tables in the database, `events`. This could result in increased
|
|
disk I/O for several hours or days after upgrading while the migration
|
|
completes. Furthermore, because we have to keep the old indexes until the new
|
|
indexes are ready, it could result in a significant, temporary, increase in
|
|
disk space.
|
|
|
|
To get a rough idea of the disk space required, check the current size of one
|
|
of the indexes. For example, from a `psql` shell, run the following sql:
|
|
|
|
```sql
|
|
SELECT pg_size_pretty(pg_relation_size('events_order_room'));
|
|
```
|
|
|
|
We need to rebuild **four** indexes, so you will need to multiply this result
|
|
by four to give an estimate of the disk space required. For example, on one
|
|
particular server:
|
|
|
|
```
|
|
synapse=# select pg_size_pretty(pg_relation_size('events_order_room'));
|
|
pg_size_pretty
|
|
----------------
|
|
288 MB
|
|
(1 row)
|
|
```
|
|
|
|
On this server, it would be wise to ensure that at least 1152MB are free.
|
|
|
|
The additional disk space will be freed once the migration completes.
|
|
|
|
SQLite databases are unaffected by this change.

# Upgrading to v1.37.0
|
|
|
|
## Deprecation of the current spam checker interface
|
|
|
|
The current spam checker interface is deprecated in favour of a new generic modules system.
|
|
Authors of spam checker modules can refer to [this
|
|
documentation](modules/porting_legacy_module.md
|
|
to update their modules. Synapse administrators can refer to [this
|
|
documentation](modules/index.md)
|
|
to update their configuration once the modules they are using have been updated.
|
|
|
|
We plan to remove support for the current spam checker interface in August 2021.
|
|
|
|
More module interfaces will be ported over to this new generic system in future versions
|
|
of Synapse.
|
|
|
|
|
|
# Upgrading to v1.34.0
|
|
|
|
## `room_invite_state_types` configuration setting
|
|
|
|
The `room_invite_state_types` configuration setting has been deprecated
|
|
and replaced with `room_prejoin_state`. See the [sample configuration
|
|
file](https://github.com/matrix-org/synapse/blob/v1.34.0/docs/sample_config.yaml#L1515).
|
|
|
|
If you have set `room_invite_state_types` to the default value you
|
|
should simply remove it from your configuration file. The default value
|
|
used to be:
|
|
|
|
```yaml
|
|
room_invite_state_types:
|
|
- "m.room.join_rules"
|
|
- "m.room.canonical_alias"
|
|
- "m.room.avatar"
|
|
- "m.room.encryption"
|
|
- "m.room.name"
|
|
```
|
|
|
|
If you have customised this value, you should remove
|
|
`room_invite_state_types` and configure `room_prejoin_state` instead.
|
|
|
|
# Upgrading to v1.33.0
|
|
|
|
## Account Validity HTML templates can now display a user's expiration date
|
|
|
|
This may affect you if you have enabled the account validity feature,
|
|
and have made use of a custom HTML template specified by the
|
|
`account_validity.template_dir` or
|
|
`account_validity.account_renewed_html_path` Synapse config options.
|
|
|
|
The template can now accept an `expiration_ts` variable, which
|
|
represents the unix timestamp in milliseconds for the future date of
|
|
which their account has been renewed until. See the [default
|
|
template](https://github.com/matrix-org/synapse/blob/release-v1.33.0/synapse/res/templates/account_renewed.html)
|
|
for an example of usage.
|
|
|
|
ALso note that a new HTML template, `account_previously_renewed.html`,
|
|
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
|
|
before. The default template contents can been found
|
|
[here](https://github.com/matrix-org/synapse/blob/release-v1.33.0/synapse/res/templates/account_previously_renewed.html),
|
|
and can also accept an `expiration_ts` variable. This template replaces
|
|
the error message users would previously see upon attempting to use a
|
|
valid renewal token more than once.
|
|
|
|
# Upgrading to v1.32.0
|
|
|
|
## Regression causing connected Prometheus instances to become overwhelmed
|
|
|
|
This release introduces [a
|
|
regression](https://github.com/matrix-org/synapse/issues/9853) that can
|
|
overwhelm connected Prometheus instances. This issue is not present in
|
|
Synapse v1.32.0rc1.
|
|
|
|
If you have been affected, please downgrade to 1.31.0. You then may need
|
|
to remove excess writeahead logs in order for Prometheus to recover.
|
|
Instructions for doing so are provided
|
|
[here](https://github.com/matrix-org/synapse/pull/9854#issuecomment-823472183).
|
|
|
|
## Dropping support for old Python, Postgres and SQLite versions
|
|
|
|
In line with our [deprecation policy](deprecation_policy.md),
|
|
we've dropped support for Python 3.5 and PostgreSQL 9.5, as they are no
|
|
longer supported upstream.
|
|
|
|
This release of Synapse requires Python 3.6+ and PostgresSQL 9.6+ or
|
|
SQLite 3.22+.
|
|
|
|
## Removal of old List Accounts Admin API
|
|
|
|
The deprecated v1 "list accounts" admin API
|
|
(`GET /_synapse/admin/v1/users/<user_id>`) has been removed in this
|
|
version.
|
|
|
|
The [v2 list accounts API](admin_api/user_admin_api.md#list-accounts)
|
|
has been available since Synapse 1.7.0 (2019-12-13), and is accessible
|
|
under `GET /_synapse/admin/v2/users`.
|
|
|
|
The deprecation of the old endpoint was announced with Synapse 1.28.0
|
|
(released on 2021-02-25).
|
|
|
|
## Application Services must use type `m.login.application_service` when registering users
|
|
|
|
In compliance with the [Application Service
|
|
spec](https://matrix.org/docs/spec/application_service/r0.1.2#server-admin-style-permissions),
|
|
Application Services are now required to use the
|
|
`m.login.application_service` type when registering users via the
|
|
`/_matrix/client/r0/register` endpoint. This behaviour was deprecated in
|
|
Synapse v1.30.0.
|
|
|
|
Please ensure your Application Services are up to date.
|
|
|
|
# Upgrading to v1.29.0
|
|
|
|
## Requirement for X-Forwarded-Proto header
|
|
|
|
When using Synapse with a reverse proxy (in particular, when using the
|
|
`x_forwarded` option on an HTTP listener), Synapse now
|
|
expects to receive an `X-Forwarded-Proto` header on incoming
|
|
HTTP requests. If it is not set, Synapse will log a warning on each
|
|
received request.
|
|
|
|
To avoid the warning, administrators using a reverse proxy should ensure
|
|
that the reverse proxy sets `X-Forwarded-Proto` header to
|
|
`https` or `http` to indicate the protocol used
|
|
by the client.
|
|
|
|
Synapse also requires the `Host` header to be preserved.
|
|
|
|
See the [reverse proxy documentation](reverse_proxy.md), where the
|
|
example configurations have been updated to show how to set these
|
|
headers.
|
|
|
|
(Users of [Caddy](https://caddyserver.com/) are unaffected, since we
|
|
believe it sets `X-Forwarded-Proto` by default.)
|
|
|
|
# Upgrading to v1.27.0
|
|
|
|
## Changes to callback URI for OAuth2 / OpenID Connect and SAML2
|
|
|
|
This version changes the URI used for callbacks from OAuth2 and SAML2
|
|
identity providers:
|
|
|
|
- If your server is configured for single sign-on via an OpenID
|
|
Connect or OAuth2 identity provider, you will need to add
|
|
`[synapse public baseurl]/_synapse/client/oidc/callback` to the list
|
|
of permitted "redirect URIs" at the identity provider.
|
|
|
|
See the [OpenID docs](openid.md) for more information on setting
|
|
up OpenID Connect.
|
|
|
|
- If your server is configured for single sign-on via a SAML2 identity
|
|
provider, you will need to add
|
|
`[synapse public baseurl]/_synapse/client/saml2/authn_response` as a
|
|
permitted "ACS location" (also known as "allowed callback URLs")
|
|
at the identity provider.
|
|
|
|
The "Issuer" in the "AuthnRequest" to the SAML2 identity
|
|
provider is also updated to
|
|
`[synapse public baseurl]/_synapse/client/saml2/metadata.xml`. 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.
|
|
|
|
## Changes to HTML templates
|
|
|
|
The HTML templates for SSO and email notifications now have [Jinja2's
|
|
autoescape](https://jinja.palletsprojects.com/en/2.11.x/api/#autoescaping)
|
|
enabled for files ending in `.html`, `.htm`, and `.xml`. If you have
|
|
customised these templates and see issues when viewing them you might
|
|
need to update them. It is expected that most configurations will need
|
|
no changes.
|
|
|
|
If you have customised the templates *names* for these templates, it is
|
|
recommended to verify they end in `.html` to ensure autoescape is
|
|
enabled.
|
|
|
|
The above applies to the following templates:
|
|
|
|
- `add_threepid.html`
|
|
- `add_threepid_failure.html`
|
|
- `add_threepid_success.html`
|
|
- `notice_expiry.html`
|
|
- `notice_expiry.html`
|
|
- `notif_mail.html` (which, by default, includes `room.html` and
|
|
`notif.html`)
|
|
- `password_reset.html`
|
|
- `password_reset_confirmation.html`
|
|
- `password_reset_failure.html`
|
|
- `password_reset_success.html`
|
|
- `registration.html`
|
|
- `registration_failure.html`
|
|
- `registration_success.html`
|
|
- `sso_account_deactivated.html`
|
|
- `sso_auth_bad_user.html`
|
|
- `sso_auth_confirm.html`
|
|
- `sso_auth_success.html`
|
|
- `sso_error.html`
|
|
- `sso_login_idp_picker.html`
|
|
- `sso_redirect_confirm.html`
|
|
|
|
# Upgrading to v1.26.0
|
|
|
|
## Rolling back to v1.25.0 after a failed upgrade
|
|
|
|
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:
|
|
|
|
1. Stop the server
|
|
|
|
2. Decrease the schema version in the database:
|
|
|
|
```sql
|
|
UPDATE schema_version SET version = 58;
|
|
```
|
|
|
|
3. Delete the ignored users & chain cover data:
|
|
|
|
```sql
|
|
DROP TABLE IF EXISTS ignored_users;
|
|
UPDATE rooms SET has_auth_chain_index = false;
|
|
```
|
|
|
|
For PostgreSQL run:
|
|
|
|
```sql
|
|
TRUNCATE event_auth_chain_links;
|
|
TRUNCATE event_auth_chains;
|
|
```
|
|
|
|
For SQLite run:
|
|
|
|
```sql
|
|
DELETE FROM event_auth_chain_links;
|
|
DELETE FROM event_auth_chains;
|
|
```
|
|
|
|
4. Mark the deltas as not run (so they will re-run on upgrade).
|
|
|
|
```sql
|
|
DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/01ignored_user.py";
|
|
DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/06chain_cover_index.sql";
|
|
```
|
|
|
|
5. Downgrade Synapse by following the instructions for your
|
|
installation method in the "Rolling back to older versions"
|
|
section above.
|
|
|
|
# Upgrading to v1.25.0
|
|
|
|
## Last release supporting Python 3.5
|
|
|
|
This is the last release of Synapse which guarantees support with Python
|
|
3.5, which passed its upstream End of Life date several months ago.
|
|
|
|
We will attempt to maintain support through March 2021, but without
|
|
guarantees.
|
|
|
|
In the future, Synapse will follow upstream schedules for ending support
|
|
of older versions of Python and PostgreSQL. Please upgrade to at least
|
|
Python 3.6 and PostgreSQL 9.6 as soon as possible.
|
|
|
|
## Blacklisting IP ranges
|
|
|
|
Synapse v1.25.0 includes new settings, `ip_range_blacklist` and
|
|
`ip_range_whitelist`, for controlling outgoing requests from Synapse for
|
|
federation, identity servers, push, and for checking key validity for
|
|
third-party invite events. The previous setting,
|
|
`federation_ip_range_blacklist`, is deprecated. The new
|
|
`ip_range_blacklist` defaults to private IP ranges if it is not defined.
|
|
|
|
If you have never customised `federation_ip_range_blacklist` it is
|
|
recommended that you remove that setting.
|
|
|
|
If you have customised `federation_ip_range_blacklist` you should update
|
|
the setting name to `ip_range_blacklist`.
|
|
|
|
If you have a custom push server that is reached via private IP space
|
|
you may need to customise `ip_range_blacklist` or `ip_range_whitelist`.
|
|
|
|
# Upgrading to v1.24.0
|
|
|
|
## Custom OpenID Connect mapping provider breaking change
|
|
|
|
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
|
|
[default
|
|
way](<https://matrix.org/docs/spec/appendices#mapping-from-other-character-sets>).
|
|
|
|
If your Synapse configuration uses a custom mapping provider
|
|
(`oidc_config.user_mapping_provider.module` is specified and
|
|
not equal to
|
|
`synapse.handlers.oidc_handler.JinjaOidcMappingProvider`)
|
|
then you *must* ensure that `map_user_attributes` of the
|
|
mapping provider performs some normalisation of the
|
|
`localpart` returned. To match previous behaviour you can
|
|
use the `map_username_to_mxid_localpart` function provided
|
|
by Synapse. An example is shown below:
|
|
|
|
```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}
|
|
```
|
|
|
|
## Removal historical Synapse Admin API
|
|
|
|
Historically, the Synapse Admin API has been accessible under:
|
|
|
|
- `/_matrix/client/api/v1/admin`
|
|
- `/_matrix/client/unstable/admin`
|
|
- `/_matrix/client/r0/admin`
|
|
- `/_synapse/admin/v1`
|
|
|
|
The endpoints with `/_matrix/client/*` prefixes have been removed as of
|
|
v1.24.0. The Admin API is now only accessible under:
|
|
|
|
- `/_synapse/admin/v1`
|
|
|
|
The only exception is the `/admin/whois` endpoint, which is
|
|
[also available via the client-server
|
|
API](https://matrix.org/docs/spec/client_server/r0.6.1#get-matrix-client-r0-admin-whois-userid).
|
|
|
|
The deprecation of the old endpoints was announced with Synapse 1.20.0
|
|
(released on 2020-09-22) and makes it easier for homeserver admins to
|
|
lock down external access to the Admin API endpoints.
|
|
|
|
# Upgrading to v1.23.0
|
|
|
|
## Structured logging configuration breaking changes
|
|
|
|
This release deprecates use of the `structured: true` logging
|
|
configuration for structured logging. If your logging configuration
|
|
contains `structured: true` then it should be modified based on the
|
|
[structured logging documentation](https://matrix-org.github.io/synapse/v1.56/structured_logging.html#upgrading-from-legacy-structured-logging-configuration).
|
|
|
|
The `structured` and `drains` logging options are now deprecated and
|
|
should be replaced by standard logging configuration of `handlers` and
|
|
`formatters`.
|
|
|
|
A future will release of Synapse will make using `structured: true` an
|
|
error.
|
|
|
|
# Upgrading to v1.22.0
|
|
|
|
## ThirdPartyEventRules breaking changes
|
|
|
|
This release introduces a backwards-incompatible change to modules
|
|
making use of `ThirdPartyEventRules` in Synapse. If you make use of a
|
|
module defined under the `third_party_event_rules` config option, please
|
|
make sure it is updated to handle the below change:
|
|
|
|
The `http_client` argument is no longer passed to modules as they are
|
|
initialised. Instead, modules are expected to make use of the
|
|
`http_client` property on the `ModuleApi` class. Modules are now passed
|
|
a `module_api` argument during initialisation, which is an instance of
|
|
`ModuleApi`. `ModuleApi` instances have a `http_client` property which
|
|
acts the same as the `http_client` argument previously passed to
|
|
`ThirdPartyEventRules` modules.
|
|
|
|
# Upgrading to v1.21.0
|
|
|
|
## Forwarding `/_synapse/client` through your reverse proxy
|
|
|
|
The [reverse proxy documentation](reverse_proxy.md)
|
|
has been updated to include reverse proxy directives for
|
|
`/_synapse/client/*` endpoints. As the user password reset flow now uses
|
|
endpoints under this prefix, **you must update your reverse proxy
|
|
configurations for user password reset to work**.
|
|
|
|
Additionally, note that the [Synapse worker documentation](workers.md) has been updated to
|
|
|
|
: state that the `/_synapse/client/password_reset/email/submit_token`
|
|
endpoint can be handled
|
|
|
|
by all workers. If you make use of Synapse's worker feature, please
|
|
update your reverse proxy configuration to reflect this change.
|
|
|
|
## New HTML templates
|
|
|
|
A new HTML template,
|
|
[password_reset_confirmation.html](https://github.com/matrix-org/synapse/blob/develop/synapse/res/templates/password_reset_confirmation.html),
|
|
has been added to the `synapse/res/templates` directory. If you are
|
|
using a custom template directory, you may want to copy the template
|
|
over and modify it.
|
|
|
|
Note that as of v1.20.0, templates do not need to be included in custom
|
|
template directories for Synapse to start. The default templates will be
|
|
used if a custom template cannot be found.
|
|
|
|
This page will appear to the user after clicking a password reset link
|
|
that has been emailed to them.
|
|
|
|
To complete password reset, the page must include a way to make a
|
|
`POST` request to
|
|
`/_synapse/client/password_reset/{medium}/submit_token` with the query
|
|
parameters from the original link, presented as a URL-encoded form. See
|
|
the file itself for more details.
|
|
|
|
## Updated Single Sign-on HTML Templates
|
|
|
|
The `saml_error.html` template was removed from Synapse and replaced
|
|
with the `sso_error.html` template. If your Synapse is configured to use
|
|
SAML and a custom `sso_redirect_confirm_template_dir` configuration then
|
|
any customisations of the `saml_error.html` template will need to be
|
|
merged into the `sso_error.html` template. These templates are similar,
|
|
but the parameters are slightly different:
|
|
|
|
- The `msg` parameter should be renamed to `error_description`.
|
|
- There is no longer a `code` parameter for the response code.
|
|
- A string `error` parameter is available that includes a short hint
|
|
of why a user is seeing the error page.
|
|
|
|
# Upgrading to v1.18.0
|
|
|
|
## Docker `-py3` suffix will be removed in future versions
|
|
|
|
From 10th August 2020, we will no longer publish Docker images with the
|
|
`-py3` tag suffix. The images tagged with the
|
|
`-py3` suffix have been identical to the non-suffixed tags
|
|
since release 0.99.0, and the suffix is obsolete.
|
|
|
|
On 10th August, we will remove the `latest-py3` tag.
|
|
Existing per-release tags (such as `v1.18.0-py3` will not
|
|
be removed, but no new `-py3` tags will be added.
|
|
|
|
Scripts relying on the `-py3` suffix will need to be
|
|
updated.
|
|
|
|
## Redis replication is now recommended in lieu of TCP replication
|
|
|
|
When setting up worker processes, we now recommend the use of a Redis
|
|
server for replication. **The old direct TCP connection method is
|
|
deprecated and will be removed in a future release.** See
|
|
[workers](workers.md) for more details.
|
|
|
|
# Upgrading to v1.14.0
|
|
|
|
This version includes a database update which is run as part of the
|
|
upgrade, and which may take a couple of minutes in the case of a large
|
|
server. Synapse will not respond to HTTP requests while this update is
|
|
taking place.
|
|
|
|
# Upgrading to v1.13.0
|
|
|
|
## Incorrect database migration in old synapse versions
|
|
|
|
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.
|
|
|
|
This will *not* be a problem for Synapse installations which were:
|
|
|
|
: - 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.
|
|
|
|
If completeness of the room directory is a concern, installations which
|
|
are affected can be repaired as follows:
|
|
|
|
1. Run the following sql from a `psql` or
|
|
`sqlite3` console:
|
|
|
|
```sql
|
|
INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
|
|
('populate_stats_process_rooms', '{}', 'current_state_events_membership');
|
|
|
|
INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
|
|
('populate_stats_process_users', '{}', 'populate_stats_process_rooms');
|
|
```
|
|
|
|
2. Restart synapse.
|
|
|
|
## New Single Sign-on HTML Templates
|
|
|
|
New templates (`sso_auth_confirm.html`, `sso_auth_success.html`, and
|
|
`sso_account_deactivated.html`) were added to Synapse. If your Synapse
|
|
is configured to use SSO and a custom
|
|
`sso_redirect_confirm_template_dir` configuration then these templates
|
|
will need to be copied from
|
|
[synapse/res/templates](synapse/res/templates) into that directory.
|
|
|
|
## Synapse SSO Plugins Method Deprecation
|
|
|
|
Plugins using the `complete_sso_login` method of
|
|
`synapse.module_api.ModuleApi` should update to using the async/await
|
|
version `complete_sso_login_async` which includes additional checks. The
|
|
non-async version is considered deprecated.
|
|
|
|
## Rolling back to v1.12.4 after a failed upgrade
|
|
|
|
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:
|
|
|
|
1. Stop the server
|
|
|
|
2. Decrease the schema version in the database:
|
|
|
|
```sql
|
|
UPDATE schema_version SET version = 57;
|
|
```
|
|
|
|
3. Downgrade Synapse by following the instructions for your
|
|
installation method in the "Rolling back to older versions"
|
|
section above.
|
|
|
|
# Upgrading to v1.12.0
|
|
|
|
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.
|
|
|
|
This is only likely to be a problem in the case of a server which is
|
|
participating in many rooms.
|
|
|
|
0. 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.
|
|
|
|
1. As an initial check to see if you will be affected, you can try
|
|
running the following query from the `psql` or
|
|
`sqlite3` console. It is safe to run it while Synapse is
|
|
still running.
|
|
|
|
```sql
|
|
SELECT MAX(q.v) FROM (
|
|
SELECT (
|
|
SELECT ej.json AS v
|
|
FROM state_events se INNER JOIN event_json ej USING (event_id)
|
|
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;
|
|
```
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
If you would prefer to reduce the downtime, continue with the steps
|
|
below.
|
|
|
|
2. The easiest workaround for this issue is to manually create a new
|
|
index before upgrading. On PostgreSQL, his can be done as follows:
|
|
|
|
```sql
|
|
CREATE INDEX CONCURRENTLY tmp_upgrade_1_12_0_index
|
|
ON state_events(room_id) WHERE type = 'm.room.create';
|
|
```
|
|
|
|
The above query may take some time, but is also safe to run while
|
|
Synapse is running.
|
|
|
|
We assume that no SQLite users have databases large enough to be
|
|
affected. If you *are* affected, you can run a similar query,
|
|
omitting the `CONCURRENTLY` keyword. Note however that this
|
|
operation may in itself cause Synapse to stop running for some time.
|
|
Synapse admins are reminded that [SQLite is not recommended for use
|
|
outside a test environment](postgres.md).
|
|
|
|
3. Once the index has been created, the `SELECT` query in step 1 above
|
|
should complete quickly. It is therefore safe to upgrade to Synapse
|
|
1.12.0.
|
|
|
|
4. Once Synapse 1.12.0 has successfully started and is responding to
|
|
HTTP requests, the temporary index can be removed:
|
|
|
|
```sql
|
|
DROP INDEX tmp_upgrade_1_12_0_index;
|
|
```
|
|
|
|
# Upgrading to v1.10.0
|
|
|
|
Synapse will now log a warning on start up if used with a PostgreSQL
|
|
database that has a non-recommended locale set.
|
|
|
|
See [Postgres](postgres.md) for details.
|
|
|
|
# Upgrading to v1.8.0
|
|
|
|
Specifying a `log_file` config option will now cause Synapse to refuse
|
|
to start, and should be replaced by with the `log_config` option.
|
|
Support for the `log_file` option was removed in v1.3.0 and has since
|
|
had no effect.
|
|
|
|
# Upgrading to v1.7.0
|
|
|
|
In an attempt to configure Synapse in a privacy preserving way, the
|
|
default behaviours of `allow_public_rooms_without_auth` and
|
|
`allow_public_rooms_over_federation` 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.
|
|
|
|
If your installation does not explicitly set these settings one way or
|
|
the other and you want either setting to be `true` then it will
|
|
necessary to update your homeserver configuration file accordingly.
|
|
|
|
For more details on the surrounding context see our
|
|
[explainer](https://matrix.org/blog/2019/11/09/avoiding-unwelcome-visitors-on-private-matrix-servers).
|
|
|
|
# Upgrading to v1.5.0
|
|
|
|
This release includes a database migration which may take several
|
|
minutes to complete if there are a large number (more than a million or
|
|
so) of entries in the `devices` table. This is only likely to a be a
|
|
problem on very large installations.
|
|
|
|
# Upgrading to v1.4.0
|
|
|
|
## New custom templates
|
|
|
|
If you have configured a custom template directory with the
|
|
`email.template_dir` option, be aware that there are new templates
|
|
regarding registration and threepid management (see below) that must be
|
|
included.
|
|
|
|
- `registration.html` and `registration.txt`
|
|
- `registration_success.html` and `registration_failure.html`
|
|
- `add_threepid.html` and `add_threepid.txt`
|
|
- `add_threepid_failure.html` and `add_threepid_success.html`
|
|
|
|
Synapse will expect these files to exist inside the configured template
|
|
directory, and **will fail to start** if they are absent. To view the
|
|
default templates, see
|
|
[synapse/res/templates](https://github.com/matrix-org/synapse/tree/master/synapse/res/templates).
|
|
|
|
## 3pid verification changes
|
|
|
|
**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.**
|
|
|
|
It is possible for a user to associate an email address or phone number
|
|
with their account, for a number of reasons:
|
|
|
|
- for use when logging in, as an alternative to the user id.
|
|
- in the case of email, as an alternative contact to help with account
|
|
recovery.
|
|
- in the case of email, to receive notifications of missed messages.
|
|
|
|
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.)
|
|
|
|
Previous versions of Synapse delegated the task of 3pid verification to
|
|
an identity server by default. In most cases this server is `vector.im`
|
|
or `matrix.org`.
|
|
|
|
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.
|
|
|
|
In the medium term, the `vector.im` and `matrix.org` 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.
|
|
|
|
Once delegated 3pid verification support has been disabled in the
|
|
`vector.im` and `matrix.org` 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 `vector.im` and `matrix.org` instances).
|
|
|
|
### Email
|
|
|
|
Following upgrade, to continue verifying email (e.g. as part of the
|
|
registration process), admins can either:-
|
|
|
|
- Configure Synapse to use an email server.
|
|
- Run or choose an identity server which allows delegated email
|
|
verification and delegate to it.
|
|
|
|
#### Configure SMTP in Synapse
|
|
|
|
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`.
|
|
|
|
See the [sample configuration file](usage/configuration/homeserver_sample_config.md)
|
|
for more details on these settings.
|
|
|
|
#### Delegate email to an identity server
|
|
|
|
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.
|
|
|
|
To this end, we will continue to support email verification delegation
|
|
via the `vector.im` and `matrix.org` identity servers for two months.
|
|
Support for delegated email verification will be disabled on Monday 2nd
|
|
December.
|
|
|
|
The `account_threepid_delegates` dictionary defines whether the
|
|
homeserver should delegate an external server (typically an [identity
|
|
server](https://matrix.org/docs/spec/identity_service/r0.2.1)) to handle
|
|
sending confirmation messages via email and SMS.
|
|
|
|
So to delegate email verification, in `homeserver.yaml`, set
|
|
`account_threepid_delegates.email` to the base URL of an identity
|
|
server. For example:
|
|
|
|
```yaml
|
|
account_threepid_delegates:
|
|
email: https://example.com # Delegate email sending to example.com
|
|
```
|
|
|
|
Note that `account_threepid_delegates.email` replaces the deprecated
|
|
`email.trust_identity_server_for_password_resets`: if
|
|
`email.trust_identity_server_for_password_resets` is set to `true`, and
|
|
`account_threepid_delegates.email` is not set, then the first entry in
|
|
`trusted_third_party_id_servers` will be used as the
|
|
`account_threepid_delegate` 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
|
|
`email.trust_identity_server_for_password_resets` is `true` and no
|
|
trusted identity server domains are configured, Synapse will report an
|
|
error and refuse to start.
|
|
|
|
If `email.trust_identity_server_for_password_resets` is `false` or
|
|
absent and no `email` delegate is configured in
|
|
`account_threepid_delegates`, then Synapse will send email verification
|
|
messages itself, using the configured SMTP server (see above). that
|
|
type.
|
|
|
|
### Phone numbers
|
|
|
|
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 `matrix.org` and `vector.im` identity servers (or another identity
|
|
server that supports SMS sending).
|
|
|
|
The `account_threepid_delegates` dictionary defines whether the
|
|
homeserver should delegate an external server (typically an [identity
|
|
server](https://matrix.org/docs/spec/identity_service/r0.2.1)) to handle
|
|
sending confirmation messages via email and SMS.
|
|
|
|
So to delegate phone number verification, in `homeserver.yaml`, set
|
|
`account_threepid_delegates.msisdn` to the base URL of an identity
|
|
server. For example:
|
|
|
|
```yaml
|
|
account_threepid_delegates:
|
|
msisdn: https://example.com # Delegate sms sending to example.com
|
|
```
|
|
|
|
The `matrix.org` and `vector.im` 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.
|
|
|
|
## Rolling back to v1.3.1
|
|
|
|
If you encounter problems with v1.4.0, it should be possible to roll
|
|
back to v1.3.1, subject to the following:
|
|
|
|
- The 'room statistics' engine was heavily reworked in this release
|
|
(see [#5971](https://github.com/matrix-org/synapse/pull/5971)),
|
|
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.
|
|
|
|
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 `homeserver.yaml`:
|
|
|
|
```yaml
|
|
stats:
|
|
enabled: false
|
|
```
|
|
|
|
Don't forget to re-enable it when you upgrade again, in preparation
|
|
for its use in the room directory!
|
|
|
|
# Upgrading to v1.2.0
|
|
|
|
Some counter metrics have been renamed, with the old names deprecated.
|
|
See [the metrics
|
|
documentation](metrics-howto.md#renaming-of-metrics--deprecation-of-old-names-in-12)
|
|
for details.
|
|
|
|
# Upgrading to v1.1.0
|
|
|
|
Synapse v1.1.0 removes support for older Python and PostgreSQL versions,
|
|
as outlined in [our deprecation
|
|
notice](https://matrix.org/blog/2019/04/08/synapse-deprecating-postgres-9-4-and-python-2-x).
|
|
|
|
## Minimum Python Version
|
|
|
|
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.
|
|
|
|
## Minimum PostgreSQL Version
|
|
|
|
If using PostgreSQL under Synapse, you will need to use PostgreSQL 9.5
|
|
or above. Please see the [PostgreSQL
|
|
documentation](https://www.postgresql.org/docs/11/upgrading.html) for
|
|
more details on upgrading your database.
|
|
|
|
# Upgrading to v1.0
|
|
|
|
## Validation of TLS certificates
|
|
|
|
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.
|
|
|
|
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_certificates` to
|
|
`false`.
|
|
- Configure a whitelist of server domains to trust via
|
|
`federation_certificate_verification_whitelist`.
|
|
|
|
See the [sample configuration file](usage/configuration/homeserver_sample_config.md)
|
|
for more details on these settings.
|
|
|
|
## Email
|
|
|
|
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](usage/configuration/homeserver_sample_config.md)
|
|
for more details on these settings.
|
|
|
|
## New email templates
|
|
|
|
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 `template_dir` in your Synapse config, these files will need to be added.
|
|
|
|
`password_reset.html` and `password_reset.txt` 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.
|
|
`password_reset_success.html` and `password_reset_failure.html` 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.
|
|
|
|
# Upgrading to v0.99.0
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.34.0
|
|
|
|
1. 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:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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: utf8` to the
|
|
`RotatingFileHandler` configuration (if you have one) in your
|
|
`<server>.log.config` file. For example, if your `log.config`
|
|
file contains:
|
|
|
|
```yaml
|
|
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:
|
|
|
|
```yaml
|
|
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](https://github.com/matrix-org/synapse/blob/release-v0.34.0/debian/NEWS)
|
|
before doing so. The existing `matrix-synapse` packages will
|
|
continue to use Python 2 for the time being.
|
|
|
|
2. This release removes the `riot.im` from the default list of trusted
|
|
identity servers.
|
|
|
|
If `riot.im` is in your homeserver's list of
|
|
`trusted_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.
|
|
|
|
3. 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_location` config option, but please consider switching
|
|
to another client.
|

# Upgrading to v0.33.7
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.27.3
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.15.0
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.11.0
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.9.0
|
|
|
|
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`:
|
|
|
|
```yaml
|
|
app_service_config_files: ["registration-01.yaml", "registration-02.yaml"]
|
|
```
|
|
|
|
Where `registration-01.yaml` looks like:
|
|
|
|
```yaml
|
|
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>
|
|
```
|
|
|
|
# Upgrading to v0.8.0
|
|
|
|
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).
|
|
|
|
# Upgrading to v0.7.0
|
|
|
|
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
|
|
|
|
# Upgrading to v0.6.0
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.5.1
|
|
|
|
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
|
|
|
|
# Upgrading to v0.5.0
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.4.0
|
|
|
|
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
|
|
|
|
# Upgrading to v0.3.0
|
|
|
|
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.
|
|
|
|
## Web Client
|
|
|
|
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.
|
|
|
|
# Upgrading to v0.2.0
|
|
|
|
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"
|
|
|
|
# Upgrading to v0.0.1
|
|
|
|
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
