Debug for #8631.
I'm having a hard time tracking down what's going wrong in that issue.
In the reported example, I could see server A sending federation traffic
to server B and all was well. Yet B reports out-of-sync device updates
from A.
I couldn't see what was _in_ the events being sent from A to B. So I
have added some crude logging to track
- when we have updates to send to a remote HS
- the edus we actually accumulate to send
- when a federation transaction includes a device list update edu
- when such an EDU is received
This is a bit of a sledgehammer.
By scraping Open Graph information from the HTML even
when an autodiscovery endpoint is found. The results are
then combined to capture as much information as possible
from the page.
I've never found this terribly useful. I think it was added in the early days
of Synapse, without much thought as to what would actually be useful to log,
and has just been cargo-culted ever since.
Rather, it tends to clutter up debug logs with useless information.
The existing implementation of the `python_twisted_reactor_tick_time` metric is pretty useless, because it *only*
measures the time taken to execute timed calls and callbacks from threads. That neglects everything that
happens off the back of I/O, which is obviously quite a lot for us.
To improve this, I've hooked into a different place in the reactor - in particular, where it calls `epoll`. That call is
the only place it should wait for something to happen - the rest of the loop *should* be quick.
I've also removed `python_twisted_reactor_pending_calls`, because I don't believe anyone ever looks at it, and
it's a nuisance to populate.
Always add state.room_id after the configurable ORDER BY. Otherwise,
for any sort, certain pages can contain results from
other pages. (Especially when sorting by creator, since there may
be many rooms by the same creator)
* Document different order direction of numerical fields
"joined_members", "joined_local_members", "version" and "state_events"
are ordered in descending direction by default (dir=f). Added a note
in tests to explain the differences in ordering.

documentation claims that you can use the %(app)s variable in password_reset and email_validation subjects, but if you do you end up with an error 500

Rather than hooking into the reactor loop, just add a timed task that runs every 100 ms to do the garbage collection.
Part 1 of a quest to simplify the reactor monkey-patching.
Currently when puppeting another user, the user doing the puppeting is
tracked for client IPs and MAU (if configured).
When tracking MAU is important, it becomes necessary to be possible to
also track the client IPs and MAU of puppeted users. As an example a
client that manages user creation and creation of tokens via the Synapse
admin API, passing those tokens for the client to use.
This PR adds optional configuration to enable tracking of puppeted users
into monthly active users. The default behaviour stays the same.

By returning all of the m.space.child state of the space, not just
the first 50. The number of rooms returned is still capped at 50.
For the federation API this implies that the requesting server will
need to individually query for any other rooms it is not joined to.
This makes the serialization of events synchronous (and it no
longer access the database), but we must manually calculate and
provide the bundled aggregations.
Overall this should cause no change in behavior, but is prep work
for other improvements.
Fixes minor discrepancies between the /hierarchy endpoint described
in MSC2946 and the implementation.
Note that the changes impact the stable and unstable /hierarchy and
unstable /spaces endpoints for both client and federation APIs.
* `_auth_and_persist_outliers`: mark persisted events as outliers
Mark any events that get persisted via `_auth_and_persist_outliers` as, well,
outliers.
Currently this will be a no-op as everything will already be flagged as an
outlier, but I'm going to change that.
* `process_remote_join`: stop flagging as outlier
The events are now flagged as outliers later on, by `_auth_and_persist_outliers`.
* `send_join`: remove `outlier=True`
The events created here are returned in the result of `send_join` to
`FederationHandler.do_invite_join`. From there they are passed into
`FederationEventHandler.process_remote_join`, which passes them to
`_auth_and_persist_outliers`... which sets the `outlier` flag.
* `get_event_auth`: remove `outlier=True`
stop flagging the events returned by `get_event_auth` as outliers. This method
is only called by `_get_remote_auth_chain_for_event`, which passes the results
into `_auth_and_persist_outliers`, which will flag them as outliers.
* `_get_remote_auth_chain_for_event`: remove `outlier=True`
we pass all the events into `_auth_and_persist_outliers`, which will now flag
the events as outliers.
* `_check_sigs_and_hash_and_fetch`: remove unused `outlier` parameter
This param is now never set to True, so we can remove it.
* `_check_sigs_and_hash_and_fetch_one`: remove unused `outlier` param
This is no longer set anywhere, so we can remove it.
* `get_pdu`: remove unused `outlier` parameter
... and chase it down into `get_pdu_from_destination_raw`.
* `event_from_pdu_json`: remove redundant `outlier` param
This is never set to `True`, so can be removed.
* changelog
* update docstring
* Fix AssertionErrors after purging events
If you purged a bunch of events from your database, and then restarted synapse
without receiving more events, then you would get a bunch of AssertionErrors on
restart.
This fixes the situation by rewinding the stream processors.
* `check-newsfragment`: ignore deleted newsfiles
Events returned by `backfill` should not be flagged as outliers.
Fixes:
```
AssertionError: null
File "synapse/handlers/federation.py", line 313, in try_backfill
dom, room_id, limit=100, extremities=extremities
File "synapse/handlers/federation_event.py", line 517, in backfill
await self._process_pulled_events(dest, events, backfilled=True)
File "synapse/handlers/federation_event.py", line 642, in _process_pulled_events

assert not event.internal_metadata.is_outlier()
```

* Push `get_room_{min,max_stream_ordering}` into StreamStore
Both implementations of this are identical, so we may as well push it down and
get rid of the abstract base class nonsense.
* Remove redundant `StreamStore` class
This is empty now
* Remove redundant `get_current_events_token`
This was an exact duplicate of `get_room_max_stream_ordering`, so let's get rid
of it.
* newsfile
* Wrap `auth.get_user_by_req` in an opentracing span
give `get_user_by_req` its own opentracing span, since it can result in a
non-trivial number of sub-spans which it is useful to group together.
This requires a bit of reorganisation because it also sets some tags (and may
force tracing) on the servlet span.
* Emit opentracing span for encoding json responses
This can be a significant time sink.
* Rename all sync spans with a prefix
* Write an opentracing span for encoding sync response
* opentracing span to group generate_room_entries
* opentracing spans within sync.encode_response
* changelog
* Use the `trace` decorator instead of context managers
This adds some opentracing annotations to ResponseCache, to make it easier to see what's going on; in particular, it adds a link back to the initial trace which is actually doing the work of generating the response.
* remove `start_active_span_from_request`
Instead, pull out a separate function, `span_context_from_request`, to extract
the parent span, which we can then pass into `start_active_span` as
normal. This seems to be clearer all round.
* Remove redundant tags from `incoming-federation-request`
These are all wrapped up inside a parent span generated in AsyncResource, so
there's no point duplicating all the tags that are set there.
* Leave request spans open until the request completes
It may take some time for the response to be encoded into JSON, and that JSON
to be streamed back to the client, and really we want that inside the top-level
span, so let's hand responsibility for closure to the SynapseRequest.
* opentracing logs for HTTP request events
* changelog
* Disable aggregation bundling on `/sync` responses
A partial revert of #11478. This turns out to have had a significant CPU impact
on initial-sync handling. For now, let's disable it, until we find a more
efficient way of achieving this.
* Fix tests.
