The + former version is now deprecated. +* 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. + +Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes +and for general upgrade guidance. + + +Notice of change to the default `git` branch for Synapse +-------------------------------------------------------- + +With the release of Synapse 1.13.0, the default `git` branch for Synapse has +changed to `develop`, which is the development tip. This is more consistent with +common practice and modern `git` usage. + +The `master` branch, which tracks the latest release, is still available. It is +recommended that developers and distributors who have scripts which run builds +using the default branch of Synapse should therefore consider pinning their +scripts to `master`. + + +Internal Changes +---------------- + +- Update the version of dh-virtualenv we use to build debs, and add focal to the list of target distributions.

([\#7177](https://github.com/matrix-org/synapse/issues/7177)). Introduced in v1.11.0. + +Synapse 1.12.0 (2020-03-23) +=========================== + +Debian packages and Docker images are rebuilt using the latest versions of +dependency libraries, including Twisted 20.3.0. **Please see security advisory +below**. + +Potential slow database update during upgrade +--------------------------------------------- + +Synapse 1.12.0 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. For imformation on seeing if you are affected, and workaround if you +are, see the [upgrade notes](UPGRADE.rst#upgrading-to-v1120). + +Security advisory +----------------- + +Synapse may be vulnerable to request-smuggling attacks when it is used with a +reverse-proxy. The vulnerabilties are fixed in Twisted 20.3.0, and are +described in +[CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108) +and +[CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109). +For a good introduction to this class of request-smuggling attacks, see +https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn. + +We are not aware of these vulnerabilities being exploited in the wild, and +do not believe that they are exploitable with current versions of any reverse +proxies. Nevertheless, we recommend that all Synapse administrators ensure that +they have the latest versions of the Twisted library to ensure that their +installation remains secure. + +* Administrators using the [`matrix.org` Docker + image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu + packages from + `matrix.org`](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#matrixorg-packages) + should ensure that they have version 1.12.0 installed: these images include + Twisted 20.3.0. +* Administrators who have [installed Synapse from + source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source) + should upgrade Twisted within their virtualenv by running: + ```sh + <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0' + ``` +* Administrators who have installed Synapse from distribution packages should + consult the information from their distributions. + +The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities. + +Advance notice of change to the default `git` branch for Synapse +---------------------------------------------------------------- + +Currently, the default `git` branch for Synapse is `master`, which tracks the +latest release. + +After the release of Synapse 1.13.0, we intend to change this default to +`develop`, which is the development tip. This is more consistent with common +practice and modern `git` usage. + +Although we try to keep `develop` in a stable state, there may be occasions +where regressions creep in. Developers and distributors who have scripts which +run builds using the default branch of `Synapse` should therefore consider +pinning their scripts to `master`. + + +Synapse 1.12.0rc1 (2020-03-19) +============================== + +Features +-------- + +- Changes related to room alias management ([MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432)): + - Publishing/removing a room from the room directory now requires the user to have a power level capable of modifying the canonical alias, instead of the room aliases.

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. + + .. code:: 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: + + .. code:: 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.

Synapse admins are reminded that + `SQLite is not recommended for use outside a test + environment <https://github.com/matrix-org/synapse/blob/master/README.rst#using-postgresql>`_. + +3.

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 +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.

GitHub gives you the opportunity to +edit the commit message before you confirm, and normally you should do so, +because the default will be useless (again: `* woops typo` is not a useful +thing to keep in the historical record). + +The main problem with this approach comes when you have a series of pull +requests which build on top of one another: as soon as you squash-merge the +first PR, you'll end up with a stack of conflicts to resolve in all of the +others. In general, it's best to avoid this situation in the first place by +trying not to have multiple related PRs in flight at the same time. Still, +sometimes that's not possible and doing a regular merge is the lesser evil. + +Another occasion in which a regular merge makes more sense is a PR where you've +deliberately created a series of commits each of which makes sense in its own +right. For example: [a PR which gradually propagates a refactoring operation +through the codebase](https://github.com/matrix-org/synapse/pull/6837), or [a +PR which is the culmination of several other +PRs](https://github.com/matrix-org/synapse/pull/5987). In this case the ability +to figure out when a particular change/bug was introduced could be very useful. + +Ultimately: **this is not a hard-and-fast-rule**. If in doubt, ask yourself “do +each of the commits I am about to merge make sense in their own right”, but +remember that we're just doing our best to balance “keeping the commit history +clean” with other factors. + +Git branching model +------------------- + +A [lot](https://nvie.com/posts/a-successful-git-branching-model/) +[of](http://scottchacon.com/2011/08/31/github-flow.html) +[words](https://www.endoflineblog.com/gitflow-considered-harmful) have been +written in the past about git branching models (no really, [a +lot](https://martinfowler.com/articles/branching-patterns.html)). I tend to +think the whole thing is overblown. Fundamentally, it's not that +complicated. Here's how we do it. + +Let's start with a picture: + + + +It looks complicated, but it's really not. There's one basic rule: *anyone* is +free to merge from *any* more-stable branch to *any* less-stable branch at +*any* time<sup id="a2">[2](#f2)</sup>. (The principle behind this is that if a +change is good enough for the more-stable branch, then it's also good enough go +put in a less-stable branch.) + +Meanwhile, merging (or squashing, as per the above) from a less-stable to a +more-stable branch is a deliberate action in which you want to publish a change +or a set of changes to (some subset of) the world: for example, this happens +when a PR is landed, or as part of our release process. + +So, what counts as a more- or less-stable branch? A little reflection will show +that our active branches are ordered thus, from more-stable to less-stable: + + * `master` (tracks our last release). + * `release-vX.Y.Z` (the branch where we prepare the next release)<sup + id="a3">[3](#f3)</sup>. + * PR branches which are targeting the release. + * `develop` (our "mainline" branch containing our bleeding-edge). + * regular PR branches. + +The corollary is: if you have a bugfix that needs to land in both +`release-vX.Y.Z` *and* `develop`, then you should base your PR on +`release-vX.Y.Z`, get it merged there, and then merge from `release-vX.Y.Z` to +`develop`. (If a fix lands in `develop` and we later need it in a +release-branch, we can of course cherry-pick it, but landing it in the release +branch first helps reduce the chance of annoying conflicts.) + +--- + +<b id="f1">[1]</b>: “Squash and merge” is GitHub's term for this +operation.

There are two ways to do this: - -- adding a ``/.well-known/matrix/server`` URL served on ``https://example.com``. -- adding a DNS ``SRV`` record in the DNS zone of domain - ``example.com``. - -Without configuring delegation, the matrix federation will -expect to find your server via ``example.com:8448``. The following methods -allow you retain a `server_name` of `example.com` so that your user IDs, room -aliases, etc continue to look like `*:example.com`, whilst having your -federation traffic routed to a different server. - -### .well-known delegation - -To use this method, you need to be able to alter the -``server_name`` 's https server to serve the ``/.well-known/matrix/server`` -URL.

The way to do this is via .well-known or an -SRV record. - -#### I have created a .well-known URI. Do I still need an SRV record? - -As of Synapse 0.99, Synapse will first check for the existence of a .well-known -URI and follow any delegation it suggests. It will only then check for the -existence of an SRV record. - -That means that the SRV record will often be redundant. However, you should -remember that there may still be older versions of Synapse in the federation -which do not understand .well-known URIs, so if you removed your SRV record -you would no longer be able to federate with them. - -It is therefore best to leave the SRV record in place for now. Synapse 0.34 and -earlier will follow the SRV record (and not care about the invalid -certificate). Synapse 0.99 and later will follow the .well-known URI, with the -correct certificate chain. - -#### Can I manage my own certificates rather than having Synapse renew certificates itself? - -Yes, you are welcome to manage your certificates yourself. Synapse will only -attempt to obtain certificates from Let's Encrypt if you configure it to do -so.The only requirement is that there is a valid TLS cert present for -federation end points. - -#### Do you still recommend against using a reverse proxy on the federation port? - -We no longer actively recommend against using a reverse proxy. Many admins will -find it easier to direct federation traffic to a reverse proxy and manage their -own TLS certificates, and this is a supported configuration. - -See [reverse_proxy.md](reverse_proxy.md) for information on setting up a -reverse proxy. - -#### Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy? - -Practically speaking, this is no longer necessary. - -If you are using a reverse proxy for all of your TLS traffic, then you can set -`no_tls: True` in the Synapse config. In that case, the only reason Synapse -needs the certificate is to populate a legacy `tls_fingerprints` field in the -federation API. This is ignored by Synapse 0.99.0 and later, and the only time -pre-0.99 Synapses will check it is when attempting to fetch the server keys - -and generally this is delegated via `matrix.org`, which will be running a modern -version of Synapse. - -#### Do I need the same certificate for the client and federation port? - -No. There is nothing stopping you from using different certificates, -particularly if you are using a reverse proxy. However, Synapse will use the -same certificate on any ports where TLS is configured. - ## Troubleshooting -You can use the [federation tester]( -<https://matrix.org/federationtester>) to check if your homeserver is -configured correctly.

It will, however, hide it from +clients. + + +## Server configuration + +Support for this feature can be enabled and configured in the +`retention` section of the Synapse configuration file (see the +[sample file](https://github.com/matrix-org/synapse/blob/v1.7.3/docs/sample_config.yaml#L332-L393)). + +To enable support for message retention policies, set the setting +`enabled` in this section to `true`. + + +### Default policy + +A default message retention policy is a policy defined in Synapse's +configuration that is used by Synapse for every room that doesn't have a +message retention policy configured in its state. This allows server +admins to ensure that messages are never kept indefinitely in a server's +database. + +A default policy can be defined as such, in the `retention` section of +the configuration file: + +```yaml + default_policy: + min_lifetime: 1d + max_lifetime: 1y +``` + +Here, `min_lifetime` and `max_lifetime` have the same meaning and level +of support as previously described. They can be expressed either as a +duration (using the units `s` (seconds), `m` (minutes), `h` (hours), +`d` (days), `w` (weeks) and `y` (years)) or as a number of milliseconds. + + +### Purge jobs + +Purge jobs are the jobs that Synapse runs in the background to purge +expired events from the database. They are only run if support for +message retention policies is enabled in the server's configuration. If +no configuration for purge jobs is configured by the server admin, +Synapse will use a default configuration, which is described in the +[sample configuration file](https://github.com/matrix-org/synapse/blob/master/docs/sample_config.yaml#L332-L393). + +Some server admins might want a finer control on when events are removed +depending on an event's room's policy. This can be done by setting the +`purge_jobs` sub-section in the `retention` section of the configuration +file. An example of such configuration could be: + +```yaml + purge_jobs: + - longest_max_lifetime: 3d + interval: 12h + - shortest_max_lifetime: 3d + longest_max_lifetime: 1w + interval: 1d + - shortest_max_lifetime: 1w + interval: 2d +``` + +In this example, we define three jobs: + +* one that runs twice a day (every 12 hours) and purges events in rooms + which policy's `max_lifetime` is lower or equal to 3 days. +* one that runs once a day and purges events in rooms which policy's + `max_lifetime` is between 3 days and a week. +* one that runs once every 2 days and purges events in rooms which + policy's `max_lifetime` is greater than a week. + +Note that this example is tailored to show different configurations and +features slightly more jobs than it's probably necessary (in practice, a +server admin would probably consider it better to replace the two last +jobs with one that runs once a day and handles rooms which which +policy's `max_lifetime` is greater than 3 days). + +Keep in mind, when configuring these jobs, that a purge job can become +quite heavy on the server if it targets many rooms, therefore prefer +having jobs with a low interval that target a limited set of rooms. Also +make sure to include a job with no minimum and one with no maximum to +make sure your configuration handles every policy. + +As previously mentioned in this documentation, while a purge job that +runs e.g. every day means that an expired event might stay in the +database for up to a day after its expiry, Synapse hides expired events +from clients as soon as they expire, so the event is not visible to +local users between its expiry date and the moment it gets purged from +the server's database. + + +### Lifetime limits + +**Note: this feature is mainly useful within a closed federation or on +servers that don't federate, because there currently is no way to +enforce these limits in an open federation.** + +Server admins can restrict the values their local users are allowed to +use for both `min_lifetime` and `max_lifetime`. These limits can be +defined as such in the `retention` section of the configuration file: + +```yaml + allowed_lifetime_min: 1d + allowed_lifetime_max: 1y +``` + +Here, `allowed_lifetime_min` is the lowest value a local user can set +for both `min_lifetime` and `max_lifetime`, and `allowed_lifetime_max` +is the highest value. Both parameters are optional (e.g. setting +`allowed_lifetime_min` but not `allowed_lifetime_max` only enforces a +minimum and no maximum). + +Like other settings in this section, these parameters can be expressed +either as a duration or as a number of milliseconds. + + +## Room configuration + +To configure a room's message retention policy, a room's admin or +moderator needs to send a state event in that room with the type +`m.room.retention` and the following content: + +```json +{ + "max_lifetime": ... +} +``` + +In this event's content, the `max_lifetime` parameter has the same +meaning as previously described, and needs to be expressed in +milliseconds. The event's content can also include a `min_lifetime` +parameter, which has the same meaning and limited support as previously +described. + +Note that over every server in the room, only the ones with support for +message retention policies will actually remove expired events.
