Allow configuring the set of workers to proxy outbound federation traffic through (`outbound_federation_restricted_to`).
This is useful when you have a worker setup with `federation_sender` instances responsible for sending outbound federation requests and want to make sure *all* outbound federation traffic goes through those instances. Before this change, the generic workers would still contact federation themselves for things like profile lookups, backfill, etc. This PR allows you to set more strict access controls/firewall for all workers and only allow the `federation_sender`'s to contact the outside world.
The original code is from @erikjohnston's branches which I've gotten in-shape to merge.
* Add IReactorUNIX to ISynapseReactor type hint.
* Create listen_unix().
Two options, 'path' to the file and 'mode' of permissions(not umask, recommend 666 as default as
nginx/other reverse proxies write to it and it's setup as user www-data)
For the moment, leave the option to always create a PID lockfile turned on by default
* Create UnixListenerConfig and wire it up.
Rename ListenerConfig to TCPListenerConfig, then Union them together into ListenerConfig.
This spidered around a bit, but I think I got it all. Metrics and manhole have been placed
behind a conditional in case of accidental putting them onto a unix socket.
Use new helpers to get if a listener is configured for TLS, and to help create a site tag
for logging.
There are 2 TODO things in parse_listener_def() to finish up at a later point.
* Refactor SynapseRequest to handle logging correctly when using a unix socket.
This prevents an exception when an IP address can not be retrieved for a request.
* Make the 'Synapse now listening on Unix socket' log line a little prettier.
* No silent failures on generic workers when trying to use a unix socket with metrics or manhole.
* Inline variables in app/_base.py
* Update docstring for listen_unix() to remove reference to a hardcoded permission of 0o666 and add a few comments saying where the default IS declared.
* Disallow both a unix socket and a ip/port combo on the same listener resource
* Linting
* Changelog
* review: simplify how listen_unix returns(and get rid of a type: ignore)
* review: fix typo from ConfigError in app/homeserver.py
* review: roll conditional for http_options.tag into get_site_tag() helper(and add docstring)
* review: enhance the conditionals for checking if a port or path is valid, remove a TODO line
* review: Try updating comment in get_client_ip_if_available to clarify what is being retrieved and why
* Pretty up how 'Synapse now listening on Unix Socket' looks by decoding the byte string.
* review: In parse_listener_def(), raise ConfigError if neither socket_path nor port is declared(and fix a typo)
* Drop support for delegating email validation
Delegating email validation to an IS is insecure (since it allows the owner of
the IS to do a password reset on your HS), and has long been deprecated. It
will now cause a config error at startup.
* Update unit test which checks for email verification
Give it an `email` config instead of a threepid delegate
* Remove unused method `requestEmailToken`
* Simplify config handling for email verification
Rather than an enum and a boolean, all we need here is a single bool, which
says whether we are or are not doing email verification.
* update docs
* changelog
* upgrade.md: fix typo
* update version number
this will be in 1.64, not 1.63
* update version number
this one too
* Make it possible to enable compression for the metrics HTTP resource
This can provide significant bandwidth savings pulling metrics from
synapse instances.
* Add changelog file.
* Fix type hint
Since the object it returns is a ReplicationCommandHandler.
This is clean-up from adding support to Redis where the command handler
was added as an additional layer of abstraction from the TCP protocol.
* Pull runtime dep checks into their own module
* Reimplement `check_requirements` using `importlib`
I've tried to make this clearer. We start by working out which of
Synapse's requirements we need to be installed here and now. I was
surprised that there wasn't an easier way to see which packages were
installed by a given extra.
I've pulled out the error messages into functions that deal with "is
this for an extra or not". And I've rearranged the loop over two
different sets of requirements into one loop with a "must be instaled"
flag.
I hope you agree that this is clearer.
* Test cases
* Add check to catch syanpse master process starting when workers are configured
* add test to verify that starting master process with worker config raises error
* newsfragment
* specify config.worker.worker_app in check
* update test
* report specific config option that triggered the error

This removes the magic allowing accessing configurable
variables directly from the config object. It is now required
that a specific configuration class is used (e.g. `config.foo`
must be replaced with `config.server.foo`).
This avoids the overhead of searching through the various
configuration classes by directly referencing the class that
the attributes are in.
It also improves type hints since mypy can now resolve the
types of the configuration variables.
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.
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.
Fixes#9890.
