When _get_state_for_groups is given a wildcard filter, just do a complete
lookup. Hopefully this will give us the best of both worlds by not filling up
the ram if we only need one or two keys, but also making the cache still work
for the federation reader usecase.
When we finish processing a request, log the number of events we fetched from
the database to handle it.
[I'm trying to figure out which requests are responsible for large amounts of
event cache churn. It may turn out to be more helpful to add counts to the
prometheus per-request/block metrics, but that is an extension to this code
anyway.]
when there is no `m.room.power_levels` event in force in the room. (PR #3397)

SECURITY UPDATE: Prevent unauthorised users from setting state events in a room
when there is no `m.room.power_levels` event in force in the room. (PR #3397)
Discussion around the Matrix Spec change proposal for this change can be
followed at https://github.com/matrix-org/matrix-doc/issues/1304.
This is only used by filter_events_for_client, so we can simplify the whole
thing by just doing one user at a time, and removing a dead storage function to
boot.
=======================================
v0.31.1 fixes a security bug in the ``get_missing_events`` federation API
where event visibility rules were not applied correctly.
We are not aware of it being actively exploited but please upgrade asap.
Bug Fixes:
* Fix event filtering in get_missing_events handler (PR #3371)

Changes in synapse v0.31.1 (2018-06-08)
=======================================
v0.31.1 fixes a security bug in the ``get_missing_events`` federation API
where event visibility rules were not applied correctly.
We are not aware of it being actively exploited but please upgrade asap.
Bug Fixes:
* Fix event filtering in get_missing_events handler (PR #3371)
Firstly, don't swallow the reason for the failure
Secondly, don't assume all exceptions are verification failures
Thirdly, log a bit of info about the key being used if debug is enabled
These "temporary fixes" have been here three and a half years, and I can't find
any events in the matrix.org database where the calculated signature differs
from what's in the db. It's time for them to go away.
======================================
Most notable change from v0.30.0 is to switch to python prometheus library to improve system
stats reporting. WARNING this changes a number of prometheus metrics in a
backwards-incompatible manner. For more details, see

Bug Fixes:
* Fix metric documentation tables (PR #3341)

The added addresses are expected to be local or loopback addresses and
shouldn't be spidered for previews.

The pagination storage function supported not specifiying a limit on the
number of events returned. This was triggered when using the search or
context API with a limit of zero, which the storage function took to
mean not being limited.
The transaction cache has some code which tries to stop it caching failures,
but if the callback function failed straight away, then things would happen
backwards and we'd end up with the failure stuck in the cache.
There's a frequent idiom I noticed where an iterable is split up into a
number of chunks/batches. Unfortunately that method does not work with
iterators like dict.keys() in python3. This implementation works with
iterators.

Server Notices use a special room which the user can't dismiss. They are
created on demand when some other bit of the code calls send_notice.
(This doesn't actually do much yet becuse we don't call send_notice anywhere)
