This adds some misc. type hints to helper methods used
in the `synapse.config` module.

The DNS threadpool must be explicitly stopped, otherwise Synapse will
hang indefinitely when asked to shut down.
|
| |
|
|
|
|
| |
This is to stop large bursts of lookups starving out other users of the
thread pools.
Fixes #11049.

interface (#10548)

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`).
|
| | |
|
| | |
|
| | |
|
| |
|
|
| |
Instead of proxying through the magic getter of the RootConfig
object. This should be more performant (and is more explicit).
|
| | |
|
| |
|
|
|
|
|
|
|
|

Use `gc.freeze()` on exit to exclude all existing objects from the final GC.
In testing, this sped up shutdown by up to a few seconds.
`gc.freeze()` runs in constant time, so there is little chance of performance
regression.

* Defer stdio redirection until we are about to start the reactor
* Catch and handle exceptions during startup
|
| |
|
| |
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 #9778
ACME v1 has been fully decommissioned for existing installs on June 1st 2021(see https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430/27), so we can now safely remove it from Synapse.
|
| |
|

As I've written in various places in the past (#7113, #9865) I'm pretty sure this is doing nothing useful at all.

* synapse.app.base: only call gc.freeze() on CPython
gc.freeze() is an implementation detail of CPython garbage collector,
and notably does not exist on PyPy.
Rather than playing whack-a-mole and skipping the call when under PyPy,
simply restrict it to CPython because the whole gc module is
implementation-defined.

We can get a SIGHUP at any point, including times where we are not in a
sane state. By deferring calling the handlers until the next reactor
tick we ensure that we don't get unexpected conflicts, e.g. trying to
flush logs from the signal handler while the code was in the process of
writing a log entry.
Fixes #8769.

This is so we can tell what is going on when things are taking a while to start up.
The main change here is to ensure that transactions that are created during startup get correctly logged like normal transactions.

This has long been something I've wanted to do. Basically the `Daemonize` code
is both too flexible and not flexible enough, in that it offers a bunch of
features that we don't use (changing UID, closing FDs in the child, logging to
syslog) and doesn't offer a bunch that we could do with (redirecting stdout/err
to a file instead of /dev/null; having the parent not exit until the child is
running).
As a first step, I've lifted the Daemonize code and removed the bits we don't
use. This should be a non-functional change. Fixing everything else will come
later.

This ended up being a bit more invasive than I'd hoped for (not helped by
generic_worker duplicating some of the code from homeserver), but hopefully
it's an improvement.
The idea is that, rather than storing unstructured `dict`s in the config for
the listener configurations, we instead parse it into a structured
`ListenerConfig` object.
|
| | |
|

This is primarily for allowing us to send those commands from workers, but for now simply allows us to ignore echoed RDATA/POSITION commands that we sent (we get echoes of sent commands when using redis). Currently we log a WARNING on the master process every time we receive an echoed RDATA.
|
| |
|
|
|
| |
This should be safe to do on all workers/masters because it is guarded by
a config option which will ensure it is only actually done on the worker
assigned as a pusher.

Ensure good comprehension hygiene using flake8-comprehensions.

This may make gc go a bit faster as the gc will know things like
caches/data stores etc. are frozen without having to check.

If acme was enabled, the sdnotify startup hook would never be run because we
would try to add it to a hook which had already fired.
There's no need to delay it: we can sdnotify as soon as we've started the
listeners.

* Configure and initialise tracer
Includes config options for the tracer and sets up JaegerClient.
* Scope manager using LogContexts
We piggy-back our tracer scopes by using log context.
The current log context gives us the current scope. If new scope is
created we create a stack of scopes in the context.
* jaeger is a dependency now
* Carrier inject and extraction for Twisted Headers
* Trace federation requests on the way in and out.
The span is created in _started_processing and closed in
_finished_processing because we need a meaningful log context.
* Create logcontext for new scope.
Instead of having a stack of scopes in a logcontext we create a new
context for a new scope if the current logcontext already has a scope.
* Remove scope from logcontext if logcontext is top level
* Disable tracer if not configured

I wanted to bring listen_tcp into line with listen_ssl in terms of returning a
list of ports, and wanted to check that was a safe thing to do - hence the
logging in `refresh_certificate`.
Also, pull the 'Synapse now listening' message up to homeserver.py, because it
was being duplicated everywhere else.

* Handle listening for ACME requests on IPv6 addresses
the weird url-but-not-actually-a-url-string doesn't handle IPv6 addresses
without extra quoting. Building a string which you are about to parse again
seems like a weird choice. Let's just use listenTCP, which is consistent with
what we do elsewhere.
* Clean up the default ACME config
make it look a bit more consistent with everything else, and tweak the defaults
to listen on port 80.
