Now that we wait for stream positions whenever we do a HTTP replication
hit, we need to be less brutal in the case where we do timeout (as we
have bugs around this).

This ensures that all other workers are told about stream updates in a timely manner, without having to remember to manually poke replication.

Closes https://github.com/matrix-org/synapse/issues/13234

Currently, we will try to start a new partial state sync every time we
perform a remote join, which is undesirable if there is already one
running for a given room.

We intend to perform remote joins whenever additional local users wish
to join a partial state room, so let's ensure that we do not start more
than one concurrent partial state sync for any given room.

------------------------------------------------------------------------

There is a race condition where the homeserver leaves a room and later
rejoins while the partial state sync from the previous membership is
still running. There is no guarantee that the previous partial state
sync will process the latest join, so we restart it if needed.

This caused some requests to fail.

This caused some requests to fail.

This really only started causing issues due to #14856

You do not have to restart synapse to reload the log config.

This should hopefully mitigate a class of races where data gets out of
sync due a HTTP replication request racing with the replication streams.

* Upgrade to new lockfile format

Now requires poetry >= 1.2.2 to read and poetry >= 1.3.0 to write.

Cheat sheet:

```
poetry --version
poetry show > scratch/before
pipx upgrade poetry
poetry --version
poetry show > scratch/after
diff scratch{before,after} && echo "no change!"
```

* Use Poetry 1.3.2 when reading or writing lockfile

* Remove unneeded(?) poetry dep for cibuildwheel

* Update docs

* Remove redundant call to setup-python

* Remove outdated comments related to Poetry 1.x

* Remove outdated docs line

was fixed in #13082

* Minor improvements to poetry cheat sheet

* Invoke setup-python-poetry with explicit version

Not sure about this. It's hardcoding versions everywhere.

* Changelog

* Check the lockfile is version 2.0

Might one day incorporate other checks like #14742

* Typo fixes, thanks Sean

Serving partial join responses is no longer experimental. They will only be served under the stable identifier if the the undocumented config flag experimental.msc3706_enabled is set to true.

Synapse continues to request a partial join only if the undocumented config flag experimental.faster_joins is set to true; this setting remains present and unaffected.

We were incorrectly checking if the *local* token had been advanced, rather than the token for the remote instance.

In practice, I don't think this has caused any bugs due to where we use `wait_for_stream_position`, as critically we don't use it on instances that also write to the given streams (and so the local token will lag behind all remote tokens).

When the local homeserver is already joined to a room and wants to
perform another remote join, we may find it useful to do a non-partial
state join if we already have the full state for the room.

This stops us from incrementing the presence stream position for no-op updates.

Fix up #14812 to avoid introducing a reference to the reactor.

* Changelog

Fixes #13852

Closes: #13643

When there are many synchronous requests waiting on a
`_PerHostRatelimiter`, each request will be started recursively just
after the previous request has completed. Under the right conditions,
this leads to stack exhaustion.

A common way for requests to become synchronous is when the remote
client disconnects early, because the homeserver is overloaded and slow
to respond.

Avoid stack exhaustion under these conditions by deferring subsequent
requests until the next reactor tick.

Fixes #14480.
