Use a custom scheme & the worker name for replication requests. (#15578)
All the information needed is already in the `instance_map`, so
use that instead of passing the hostname / IP & port manually
for each replication request.

This consolidates logic for future improvements of using e.g.
UNIX sockets for workers.

HTTP Replication Client (#15470)
Separate out a HTTP client for replication in preparation for
also supporting using UNIX sockets. The major difference from
the base class is that this does not use treq to handle HTTP
requests.

Revert "Reduce the size of the HTTP connection pool for non-pushers" (#15530)
#15514 introduced a regression where Synapse would encounter
`PartialDownloadError`s when fetching OpenID metadata for certain
providers on startup. Due to #8088, this prevents Synapse from starting
entirely.

Revert the change while we decide what to do about the regression.

Reduce the size of the HTTP connection pool for non-pushers. (#15514)
Pushers tend to make many connections to the same HTTP host
(e.g. a new event comes in, causes events to be pushed, and then
the homeserver connects to the same host many times). Due to this
the per-host HTTP connection pool size was increased, but this does
not make sense for other SimpleHttpClients.

Add a parameter for the connection pool and override it for pushers
(making a separate SimpleHttpClient for pushers with the increased
configuration).

This returns the HTTP connection pool settings to the default Twisted
ones for non-pusher HTTP clients.

Call appservices on modern paths, falling back to legacy paths. (#15317)
This uses the specced /_matrix/app/v1/... paths instead of the
"legacy" paths. If the homeserver receives an error it will retry
using the legacy path.

Experimental Unix socket support (#15353)
* 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)

Use mypy 1.0 (#15052)
* Update mypy and mypy-zope
* Remove unused ignores

These used to suppress

```
synapse/storage/engines/__init__.py:28: error: "__new__" must return a
class instance (got "NoReturn")  [misc]
```

and

```
synapse/http/matrixfederationclient.py:1270: error: "BaseException" has no attribute "reasons"  [attr-defined]
```

(note that we check `hasattr(e, "reasons")` above)

* Avoid empty body warnings, sometimes by marking methods as abstract

E.g.

```
tests/handlers/test_register.py:58: error: Missing return statement  [empty-body]
tests/handlers/test_register.py:108: error: Missing return statement  [empty-body]
```

* Suppress false positive about `JaegerConfig`

Complaint was

```
synapse/logging/opentracing.py:450: error: Function "Type[Config]" could always be true in boolean context  [truthy-function]
```

* Fix not calling `is_state()`

Oops!

```
tests/rest/client/test_third_party_rules.py:428: error: Function "Callable[[], bool]" could always be true in boolean context  [truthy-function]
```

* Suppress false positives from ParamSpecs

````
synapse/logging/opentracing.py:971: error: Argument 2 to "_custom_sync_async_decorator" has incompatible type "Callable[[Arg(Callable[P, R], 'func'), **P], _GeneratorContextManager[None]]"; expected "Callable[[Callable[P, R], **P], _GeneratorContextManager[None]]"  [arg-type]

* Drive-by improvement to `wrapping_logic` annotation

* Workaround false "unreachable" positives

* Pull in updated canonicaljson lib

so the protocol check just works

* Improve comments in opentracing

I tried to workaround the ignores but found it too much trouble.

I think the corresponding issue is
https://github.com/python/mypy/issues/12909. The mypy repo has a PR
claiming to fix this (https://github.com/python/mypy/pull/14677) which
might mean this gets resolved soon?

Add helper to parse an enum from query args & use it. (#14956)
The `parse_enum` helper pulls an enum value from the query string
(by delegating down to the parse_string helper with values generated
from the enum).

This is used to pull out "f" and "b" in most places and then we thread
the resulting Direction enum throughout more code.

Indicate what endpoint came back with a JSON response we were unable to parse (#14097)
**Before:**
```
WARNING - POST-11 - Unable to parse JSON: Expecting value: line 1 column 1 (char 0) (b'')
```

**After:**
```
WARNING - POST-11 - Unable to parse JSON from POST /_matrix/client/v3/join/%21ZlmJtelqFroDRJYZaq:hs1?server_name=hs1 response: Expecting value: line 1 column 1 (char 0) (b'')
```

---

It's possible to figure out which endpoint these warnings were coming from before but you had to follow the request ID `POST-11` to the log line that says `Completed request [...]`. Including this key information next to the JSON parsing error makes it much easier to reason whether it matters or not.

```

---

As a note, having no `body` is normal for the `/join` endpoint and it can handle it.

0c853e0970/synapse/rest/client/room.py (L398-L403)

Alternatively we could remove these extra logs but they are probably more usually helpful to figure out what went wrong.

synapse.api.auth.Auth cleanup: make permission-related methods use Requester instead of the UserID (#13024)
Part of #13019

This changes all the permission-related methods to rely on the Requester instead of the UserID. This is a first step towards enabling scoped access tokens at some point, since I expect the Requester to have scope-related informations in it.

It also changes methods which figure out the user/device/appservice out of the access token to return a Requester instead of something else. This avoids having store-related objects in the methods signatures.

053ca5f3ca Synapse 1.60.0rc2 (2022-05-27)
==============================
 
 This release of Synapse adds a unique index to the `state_group_edges` table, in
 order to prevent accidentally introducing duplicate information (for example,
 because a database backup was restored multiple times). If your Synapse database
 already has duplicate rows in this table, this could fail with an error and
 require manual remediation.
 
 Additionally, the signature of the `check_event_for_spam` module callback has changed.
 The previous signature has been deprecated and remains working for now. Module authors
 should update their modules to use the new signature where possible.
 
 See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600)
 for more details.
 
 Features
 --------
 
 - Add an option allowing users to use their password to reauthenticate for privileged actions even though password login is disabled. ([\#12883](https://github.com/matrix-org/synapse/issues/12883))
 
 Bugfixes

 - Explicitly close `ijson` coroutines once we are done with them, instead of leaving the garbage collector to close them. ([\#12875](https://github.com/matrix-org/synapse/issues/12875))

Make handling of federation Authorization header (more) compliant with RFC7230 (#12774)
The main differences are:
- values with delimiters (such as colons) should be quoted, so always
  quote the origin, since it could contain a colon followed by a port
  number
- should allow more than one space after "X-Matrix"

Respect the @cancellable flag for RestServlets and BaseFederationServlets (#12699)
Both `RestServlet`s and `BaseFederationServlet`s register their handlers
with `HttpServer.register_paths` / `JsonResource.register_paths`. Update
`JsonResource` to respect the `@cancellable` flag on handlers registered
in this way.

Although `ReplicationEndpoint` also registers itself using
`register_paths`, it does not pass the handler method that would have the
`@cancellable` flag directly, and so needs separate handling.

Respect the @cancellable flag for DirectServe{Html,Json}Resources (#12698)
`DirectServeHtmlResource` and `DirectServeJsonResource` both inherit
from `_AsyncResource`. These classes expect to be subclassed with
`_async_render_*` methods.

This commit has no effect on `JsonResource`, despite inheriting from
`_AsyncResource`. `JsonResource` has its own `_async_render` override
which will need to be updated separately.

Capture the Deferred for request cancellation in _AsyncResource (#12694)
All async request processing goes through `_AsyncResource`, so this is
the only place where a `Deferred` needs to be captured for cancellation.

Unfortunately, the same isn't true for determining whether a request
can be cancelled. Each of `RestServlet`, `BaseFederationServlet`,
`DirectServe{Html,Json}Resource` and `ReplicationEndpoint` have
different wrappers around the method doing the request handling and they
all need to be handled separately.
