Currently when a new build of the docs is created, an `index.html` file does not exist. Typically this would be generated from a`docs/README.md` file - which we have - however we're currently using [docs/README.md](394673055d/docs/README.md) to explain the docs and point to the website. It is not part of the content of the website. So we end up not having an `index.html` file, which will result in a 404 page if one tries to navigate to `https://matrix-org.github.io/synapse/<docs_version>/index.html`.
This isn't a really problem for the default version of the documentation (currently `develop`), as [navigating to the top-level root](https://matrix-org.github.io/synapse/) of the website (without specifying a version) will [redirect](a77e6925f2/index.html (L2)) you to the Welcome and Overview page of the `develop` docs version.
However, ideally once we add a GUI for switching between versions, we'll want to send the user to `matrix-org.github.io/synapse/<version>/index.html`, which currently isn't generated.
This PR modifies the CI that builds the docs to simply copy the rendered [Welcome & Overview page](https://matrix-org.github.io/synapse/develop/welcome_and_overview.html) to `index.html`.
The idea here is to stop people sending things that aren't joins/leaves/knocks through these endpoints: previously you could send anything you liked through them. I wasn't able to find any security holes from doing so, but it doesn't sound like a good thing.

Fixes#10233 (at least to some extent)
* Drop Origin & Accept from Access-Control-Allow-Headers value
This change drops the Origin and Accept header names from the value of the
Access-Control-Allow-Headers response header sent by Synapse. Per the CORS
protocol, it’s not necessary or useful to include those header names.
Details:
Per-spec at https://fetch.spec.whatwg.org/#forbidden-header-name, Origin
is a “forbidden header name” set by the browser and that frontend
JavaScript code is never allowed to set.
So the value of Access-Control-Allow-Headers isn’t relevant to Origin or
in general to other headers set by the browser itself — the browser
never ever consults the Access-Control-Allow-Headers value to confirm
that it’s OK for the request to include an Origin header.
And per-spec at https://fetch.spec.whatwg.org/#cors-safelisted-request-header,
Accept is a “CORS-safelisted request-header”, which means that browsers
allow requests to contain the Accept header regardless of whether the
Access-Control-Allow-Headers value contains "Accept".
So it’s unnecessary for the Access-Control-Allow-Headers to explicitly
include Accept. Browsers will not perform a CORS preflight for requests
containing an Accept request header.

We were repeatedly looking up a config option in a loop (using the
unclassed config style), which is expensive enough that it can cause
large CPU usage.
An accidental mis-ordering of operations during #6739 technically allowed an incoming knock event over federation in before checking it against any configured Third Party Access Rules modules.
This PR corrects that by performing the TPAR check *before* persisting the event.
This PR will run a new "Deploy release-specific documentation" job whenever a push to a branch name matching `release-v*` occurs. Doing so will create/add to a folder named `vX.Y` on the `gh-pages` branch. Doing so will allow us to build up `major.minor` releases of the docs as we release Synapse.
This is especially useful for having a mechanism for keeping around documentation of old/removed features (for those running older versions of Synapse), without needing to clutter the latest copy of the docs.
After a [discussion](https://matrix.to/#/!XaqDhxuTIlvldquJaV:matrix.org/$rKmkBmQle8OwTlGcoyu0BkcWXdnHW3_oap8BMgclwIY?via=matrix.org&via=vector.modular.im&via=envs.net) in #synapse-dev, we wanted to use tags to trigger the documentation deployments, which I agreed with. However, I soon realised that the bash-foo required to turn a tag of `v1.2.3rc1` into `1.2` was a lot more complex than the branch's `release-v1.2`. So, I've gone with the latter for simplicity.
In the future we'll have some UI on the website to switch between versions, but for now you can simply just change 'develop' to 'v1.2' in the URL.
This could cause a minor data leak if someone defined a non-restricted join rule
with an allow key or used a restricted join rule in an older room version, but this is
unlikely.
Additionally this starts adding unit tests to the spaces summary handler.
This PR adds a common configuration section for all modules (see docs). These modules are then loaded at startup by the homeserver. Modules register their hooks and web resources using the new `register_[...]_callbacks` and `register_web_resource` methods of the module API.
Fixes https://github.com/matrix-org/synapse/issues/10030.
We were expecting milliseconds where we should have provided a value in seconds.
The impact of this bug isn't too bad. The code is intended to count the number of remote servers that the homeserver can see and report that as a metric. This metric is supposed to run initially 1 second after server startup, and every 60s as well. Instead, it ran 1,000 seconds after server startup, and every 60s after startup.
This fix allows for the correct metrics to be collected immediately, as well as preventing a random collection 1,000s in the future after startup.
Dangerous actions means deactivating an account, modifying an account
password, or adding a 3PID.
Other actions (deleting devices, uploading keys) can re-use the same UI
auth session if ui_auth.session_timeout is configured.
This doc is short but a useful guide to what the request log lines mean.

This is the first of two PRs which seek to address #8518. This first PR lays the groundwork by extending ResponseCache; a second PR (#10158) will update the SyncHandler to actually use it, and fix the bug.
The idea here is that we allow the callback given to ResponseCache.wrap to decide whether its result should be cached or not. We do that by (optionally) passing a ResponseCacheContext into it, which it can modify.

This is essentially an implementation of the proposal made at https://hackmd.io/@richvdh/BJYXQMQHO, though the details have ended up looking slightly different.
This implements similar behavior to sytest where a matching branch is used,
if one exists. This is useful when needing to modify both application code
and tests at the same time. The following rules are used to find a matching
complement branch:
1. Search for the branch name of the pull request. (E.g. feature/foo.)
2. Search for the base branch of the pull request. (E.g. develop or release-vX.Y.)
3. Search for the reference branch of the commit. (E.g. master or release-vX.Y.)
4. Fallback to 'master', the default complement branch name.
Spawned from missing messages we were seeing on `matrix.org` from a
federated Gtiter bridged room, https://gitlab.com/gitterHQ/webapp/-/issues/2770.
The underlying issue in Synapse is tracked by https://github.com/matrix-org/synapse/issues/10066
where the message and join event race and the message is `soft_failed` before the
`join` event reaches the remote federated server.
Less soft_failed events = better and usually this should only trigger for events
where people are doing bad things and trying to fuzz and fake everything.
This PR updates the build tags that we perform Complement runs with to match our [buildkite pipeline](618b3e90bc/synapse/pipeline.yml (L570)), as well as adding `msc2403` (as it will be required once #9359 is merged). Build tags are what we use to determine which tests to run in Complement (really it determines which test files are compiled into the final binary).
I haven't put in a comment about updating the buildkite side here, as we've decided to migrate fully to GitHub Actions anyhow.
With the prior format, 1.33.0 / 1.33.1 / 1.33.2 got separate branches:
release-v1.33.0
release-v1.33.1
release-v1.33.2
Under the new model, all three would share a common branch:
release-v1.33
As before, RCs and actual releases exist as tags on these branches.
This better reflects our support model, e.g., that the "1.33" series had
a formal release followed by two patches / updates.

Fixes#1834.
`get_new_events_for_appservice` internally calls `get_events_as_list`, which will filter out any rejected events. If all returned events are filtered out, `_notify_interested_services` will return without updating the last handled stream position. If there are 100 consecutive such events, processing will halt altogether.
Breaking the loop is now done by checking whether we're up-to-date with `current_max` in the loop condition, instead of relying on an empty `events` list.

If backfilling is slow then the client may time out and retry, causing
Synapse to start a new `/backfill` before the existing backfill has
finished, duplicating work.
This adds quite a lot of OpenTracing decoration for database activity. Specifically it adds tracing at four different levels:
* emit a span for each "interaction" - ie, the top level database function that we tend to call "transaction", but isn't really, because it can end up as multiple transactions.
* emit a span while we hold a database connection open
* emit a span for each database transaction - actual actual transaction.
* emit a span for each database query.
I'm aware this might be quite a lot of overhead, but even just running it on a local Synapse it looks really interesting, and I hope the overhead can be offset just by turning down the sampling frequency and finding other ways of tracing requests of interest (eg, the `force_tracing_for_users` setting).
The existing tracing reports an error each time there is a timeout, which isn't
really representative.
Additionally, we log things about the way `wait_for_events` works
(eg, the result of the callback) to the *parent* span, which is confusing.
So that they render nicely in mdbook (see #10086), and so that we no longer have a mix of structured text languages in our documentation (excluding files outside of `docs/`).
Empirically, this helped my server considerably when handling gaps in Matrix HQ. The problem was that we would repeatedly call have_seen_events for the same set of (50K or so) auth_events, each of which would take many minutes to complete, even though it's only an index scan.

https://github.com/matrix-org/synapse/issues/9962 uncovered that we accidentally removed all but one of the presence updates that we store in the database when persisting multiple updates. This could cause users' presence state to be stale.
The bug was fixed in #10014, and this PR just adds a test that failed on the old code, and was used to initially verify the bug.
The test attempts to insert some presence into the database in a batch using `PresenceStore.update_presence`, and then simply pulls it out again.
Fixes: https://github.com/matrix-org/synapse/issues/9962

Also add support for giving a callback to generate the JSON object to
verify. This should reduce memory usage, as we no longer have the event
in memory in dict form (which has a large memory footprint) for extend
periods of time.
Instead of parsing the full response to `/send_join` into Python objects (which can be huge for large rooms) and *then* parsing that into events, we instead use ijson to stream parse the response directly into `EventBase` objects.
To be more consistent with similar code. The check now automatically
raises an AuthError instead of passing back a boolean. It also absorbs
some shared logic between callers.
- use a tuple rather than a list for the iterable that is passed into the
wrapped function, for performance
- test that we can pass an iterable and that keys are correctly deduped.
It's not obvious that instances of SQLBaseStore each need their own
instances of random.SystemRandom(); let's just use random directly.

This should help ensure that equivalent results are achieved between
homeservers querying for the summary of a space.
This implements modified MSC1772 rules, according to MSC2946.
The different is that the origin_server_ts of the m.room.create event
is not used as a tie-breaker since this might not be known if the
homeserver is not part of the room.
Per changes in MSC2946, the C-S and S-S APIs for spaces summary
should use GET requests.
Until this is stable, the POST endpoints still exist.
This does not switch federation requests to use the GET version yet
since it is newly added and already deployed servers might not support
it. When switching to the stable endpoint we should switch to GET
requests.
MSC1772 specifies the m.room.create event should be sent as part
of the invite_state. This was done optionally behind an experimental
flag, but is now done by default due to MSC1772 being approved.
Now that cross signing exists there is much less of a need for other people to look at devices and verify them individually. This PR adds a config option to allow you to prevent device display names from being shared with other servers.

We were pulling the full auth chain for the room out of the DB each time
we backfilled, which can be *huge* for large rooms and is totally
unnecessary.
The hope here is that by moving all the schema files into synapse/storage/schema, it gets a bit easier for newcomers to navigate.
It certainly got easier for me to write a helpful README. There's more to do on that front, but I'll follow up with other PRs for that.
This is an update based on changes to MSC2946. The origin_server_ts
of the m.room.create event is copied into the creation_ts field for each
room returned from the spaces summary.
Synapse can be quite memory intensive, and unless care is taken to tune
the GC thresholds it can end up thrashing, causing noticable performance
problems for large servers. We fix this by limiting how often we GC a
given generation, regardless of current counts/thresholds.
This does not help with the reverse problem where the thresholds are set
too high, but that should only happen in situations where they've been
manually configured.
Adds a `gc_min_seconds_between` config option to override the defaults.

This fixes a regression where the logging context for runWithConnection
was reported as runWithConnection instead of the connection name,
e.g. "POST-XYZ".
I went through and removed a bunch of cruft that was lying around for compatibility with old Python versions. This PR also will now prevent Synapse from starting unless you're running Python 3.6+.
This ensures that something like an auth error (403) will be
returned to the requester instead of attempting to try more
servers, which will likely result in the same error, and then
passing back a generic 400 error.
First of all, a fixup to `FakeChannel` which is needed to make it work with the default HTTP channel implementation.
Secondly, it looks like we no longer need `_PushHTTPChannel`, because as of #8013, the producer that gets attached to the `HTTPChannel` is now an `IPushProducer`. This is good, because it means we can remove a whole load of test-specific boilerplate which causes variation between tests and production.
Applied a (slightly modified) patch from https://github.com/matrix-org/synapse/issues/9574.

This attempts to be a direct port of https://github.com/matrix-org/synapse-dinsic/pull/74 to mainline. There was some fiddling required to deal with the changes that have been made to mainline since (mainly dealing with the split of `RegistrationWorkerStore` from `RegistrationStore`, and the changes made to `self.make_request` in test code).

This basically speeds up federation by "squeezing" each individual dual database call (to destinations and destination_rooms), which previously happened per every event, into one call for an entire batch (100 max).

This PR adds a Dockerfile and some supporting files to the `docker/` directory. The Dockerfile's intention is to spin up a container with:
* A Synapse main process.
* Any desired worker processes, defined by a `SYNAPSE_WORKERS` environment variable supplied at runtime.
* A redis for worker communication.
* A nginx for routing traffic.
* A supervisord to start all worker processes and monitor them if any go down.
Note that **this is not currently intended to be used in production**. If you'd like to use Synapse workers with Docker, instead make use of the official image, with one worker per container. The purpose of this dockerfile is currently to allow testing Synapse in worker mode with the [Complement](https://github.com/matrix-org/complement/) test suite.
`configure_workers_and_start.py` is where most of the magic happens in this PR. It reads from environment variables (documented in the file) and creates all necessary config files for the processes. It is the entrypoint of the Dockerfile, and thus is run any time the docker container is spun up, recreating all config files in case you want to use a different set of workers. One can specify which workers they'd like to use by setting the `SYNAPSE_WORKERS` environment variable (as a comma-separated list of arbitrary worker names) or by setting it to `*` for all worker processes. We will be using the latter in CI.
Huge thanks to @MatMaul for helping get this all working 🎉 This PR is paired with its equivalent on the Complement side: https://github.com/matrix-org/complement/pull/62.
Note, for the purpose of testing this PR before it's merged: You'll need to (re)build the base Synapse docker image for everything to work (`matrixdotorg/synapse:latest`). Then build the worker-based docker image on top (`matrixdotorg/synapse:workers`).
Context is in https://github.com/matrix-org/synapse/issues/9764#issuecomment-818615894.
I struggled to find a more official link for this. The problem occurs when using WSL1 instead of WSL2, which some Windows platforms (at least Server 2019) still don't have. Docker have updated their documentation to paint a much happier picture now given WSL2's support.
The last sentence here can probably be removed once WSL1 is no longer around... though that will likely not be for a very long time.

When joining a room with join rules set to 'restricted', check if the
user is a member of the spaces defined in the 'allow' key of the join rules.
This only applies to an experimental room version, as defined in MSC3083.
This PR modifies `GaugeBucketCollector` to only report data once it has been updated, rather than initially reporting a value of 0. Fixes zero values being reported for some metrics on startup until a background job to update the metric's value runs later.
At the moment, if you'd like to share presence between local or remote users, those users must be sharing a room together. This isn't always the most convenient or useful situation though.
This PR adds a module to Synapse that will allow deployments to set up extra logic on where presence updates should be routed. The module must implement two methods, `get_users_for_states` and `get_interested_users`. These methods are given presence updates or user IDs and must return information that Synapse will use to grant passing presence updates around.
A method is additionally added to `ModuleApi` which allows triggering a set of users to receive the current, online presence information for all users they are considered interested in. This is the equivalent of that user receiving presence information during an initial sync.
The goal of this module is to be fairly generic and useful for a variety of applications, with hard requirements being:
* Sending state for a specific set or all known users to a defined set of local and remote users.
* The ability to trigger an initial sync for specific users, so they receive all current state.
The `remote_media_cache_thumbnails_media_origin_media_id_thumbna_key`
constraint is superceded by
`remote_media_repository_thumbn_media_origin_id_width_height_met` (which adds
`thumbnail_method` to the unique key).
PR #7124 made an attempt to remove the old constraint, but got the name wrong,
so it didn't work. Here we update the bg update and rerun it.

* You can now specify a regex of test names to run, or just run all tests.
* We now use the Synapse test blacklist tag (so all tests will pass).
`room_invite_state_types` was inconvenient as a configuration setting, because
anyone that ever set it would not receive any new types that were added to the
defaults. Here, we deprecate the old setting, and replace it with a couple of
new settings under `room_prejoin_state`.
This should fix a class of bug where we forget to check if e.g. the appservice shouldn't be ratelimited.
We also check the `ratelimit_override` table to check if the user has ratelimiting disabled. That table is really only meant to override the event sender ratelimiting, so we don't use any values from it (as they might not make sense for different rate limits), but we do infer that if ratelimiting is disabled for the user we should disabled all ratelimits.
Fixes#9663
I've reiterated the advice about using `oidc` to migrate, since I've seen a few
people caught by this.
I've also removed a couple of the examples as they are duplicating the OIDC
documentation, and I think they might be leading people astray.
If you have the wrong version of `cryptography` installed, synapse suggests:
```
To install run:
pip install --upgrade --force 'cryptography>=3.4.7;python_version>='3.6''
```
However, the use of ' inside '...' doesn't work, so when you run this, you get
an error.
Make pip install faster in Docker build for [Complement](https://github.com/matrix-org/complement) testing.
If files have changed in a `COPY` command, Docker will invalidate all of the layers below. So I changed the order of operations to install all dependencies before we `COPY synapse /synapse/synapse/`. This allows Docker to use our cached layer of dependencies even when we change the source of Synapse and speed up builds dramatically! `53.5s` -> `3.7s` builds 🤘
As an alternative, I did try using BuildKit caches but this still took 30 seconds overall on that step. 15 seconds to gather the dependencies from the cache and another 15 seconds to `Installing collected packages`.
Fix https://github.com/matrix-org/synapse/issues/9364
Running `dmypy run` will do a `mypy` check while spinning up a daemon
that makes rerunning `dmypy run` a lot faster.
`dmypy` doesn't support `follow_imports = silent` and has
`local_partial_types` enabled, so this PR enables those options and
fixes the issues that were newly raised. Note that `local_partial_types`
will be enabled by default in upcoming mypy releases.
Make it clearer in the source install step that the platform specific
prerequisites must be installed first.

Split off from https://github.com/matrix-org/synapse/pull/9491
Adds a storage method for getting the current presence of all local users, optionally excluding those that are offline. This will be used by the code in #9491 when a PresenceRouter module informs Synapse that a given user should have `"ALL"` user presence updates routed to them. Specifically, it is used here: b588f16e39/synapse/handlers/presence.py (L1131-L1133)
Note that there is a `get_all_presence_updates` function just above. That function is intended to walk up the table through stream IDs, and is primarily used by the presence replication stream. I could possibly make use of it in the PresenceRouter-related code, but it would be a bit of a bodge.
Builds on the work done in #9643 to add a federation API for space summaries.
There's a bit of refactoring of the existing client-server code first, to avoid too much duplication.
Currently federation catchup will send the last *local* event that we
failed to send to the remote. This can cause issues for large rooms
where lots of servers have sent events while the remote server was down,
as when it comes back up again it'll be flooded with events from various
points in the DAG.
Instead, let's make it so that all the servers send the most recent
events, even if its not theirs. The remote should deduplicate the
events, so there shouldn't be much overhead in doing this.
Alternatively, the servers could only send local events if they were
also extremities and hope that the other server will send the event
over, but that is a bit risky.
This bug was discovered by DINUM. We were modifying `serialized_event["content"]`, which - if you've got `USE_FROZEN_DICTS` turned on or are [using a third party rules module](17cd48fe51/synapse/events/third_party_rules.py (L73-L76)) - will raise a 500 if you try to a edit a reply to a message.
`serialized_event["content"]` could be set to the edit event's content, instead of a copy of it, which is bad as we attempt to modify it. Instead, we also end up modifying the original event's content. DINUM uses a third party rules module, which meant the event's content got frozen and thus an exception was raised.
To be clear, the problem is not that the event's content was frozen. In fact doing so helped us uncover the fact we weren't copying event content correctly.
We had two functions named `get_forward_extremities_for_room` and
`get_forward_extremeties_for_room` that took different paramters. We
rename one of them to avoid confusion.
* Populate `internal_metadata.outlier` based on `events` table
Rather than relying on `outlier` being in the `internal_metadata` column,
populate it based on the `events.outlier` column.
* Move `outlier` out of InternalMetadata._dict
Ultimately, this will allow us to stop writing it to the database. For now, we
have to grandfather it back in so as to maintain compatibility with older
versions of Synapse.
Instead of if the user does not have a password hash. This allows a SSO
user to add a password to their account, but only if the local password
database is configured.
