Make sure that the user has permission to view the requeseted event for
/event/{eventId} and /room/{roomId}/event/{eventId} requests.
Also check that the event is in the given room for
/room/{roomId}/event/{eventId}, for sanity.
When we get a federation request which refers to an event id, make sure that
said event is in the room the caller claims it is in.
(patch supplied by @turt2live)
This code brings the SimpleHttpClient into line with the
MatrixFederationHttpClient by having it raise HttpResponseExceptions when a
request fails (rather than trying to parse for matrix errors and maybe raising
MatrixCodeMessageException).
Then, whenever we were checking for MatrixCodeMessageException and turning them
into SynapseErrors, we now need to check for HttpResponseExceptions and call
to_synapse_error.
* attempt at deduplicating lazy-loaded members
as per the proposal; we can deduplicate redundant lazy-loaded members
which are sent in the same sync sequence. we do this heuristically
rather than requiring the client to somehow tell us which members it
has chosen to cache, by instead caching the last N members sent to
a client, and not sending them again. For now we hardcode N to 100.
Each cache for a given (user,device) tuple is in turn cached for up to
X minutes (to avoid the caches building up). For now we hardcode X to 30.
* add include_redundant_members filter option & make it work
* remove stale todo
* add tests for _get_some_state_from_cache
* incorporate review
It turns out that looping_call does check the deferred returned by its
callback, and (at least in the case of client_ips), we were relying on this,
and I broke it in #3604.
Update run_as_background_process to return the deferred, and make sure we
return it to clock.looping_call.
_update_remote_profile_cache was missing its `defer.inlineCallbacks`, so when
it was called, would just return a generator object, without actually running
any of the method body.
This allows us to handle /context/ requests on the client_reader worker
without having to pull in all the various stream handlers (e.g.
precence, typing, pushers etc). The only thing the token gets used for
is pagination, and that ignores everything but the room portion of the
token.
Previously we only queried the device list when the user joined the room; now we
do it when they are invited too. This means that new messages can be encrypted
for the devices of the invited user as of the point they were invited.
WARNING: This commit has two major problems however:
1. If the invited user adds devices after being invited but before joining, the
device-list will not be updated to the other servers in the room (as we don't
know who those servers are).
2. This introduces a regression, as previously the device-list would be correctly
updated when when user joined the room. However, this resync doesn't happen
now, so devices which joined after the invite and before the join may never
be added to the device-list.
This is being merged for DINSIC given the edge case of adding devices between
invite & join is pretty rare in their use case, but before it can be merged to
synapse in general we need to at least re-sync the devicelist when the user joins
or to implement some kind of pubsub mechanism to let interested servers subscribe
to devicelist updates on other servers irrespective of user join/invite membership.

Most rooms have a trivial history visibility like "shared" or
"world_readable", especially large rooms, so lets not bother getting the
full membership of those rooms in that case.
when there is no `m.room.power_levels` event in force in the room. (PR #3397)
