* Fix servlet metric names

* Remove redundant check
* Cover all return paths
First of all, let's get rid of `TOKEN_NOT_FOUND_HTTP_STATUS`. It was a hack we
did at one point when it was possible to return either a 403 or a 401 if the
creds were missing. We always return a 401 in these cases now (thankfully), so
it's not needed.
Let's also stop abusing `AuthError` for these cases. Honestly they have nothing
that relates them to the other places that `AuthError` is used, other than the
fact that they are loosely under the 'Auth' banner. It makes no sense for them
to share exception classes.
Instead, let's add a couple of new exception classes: `InvalidClientTokenError`
and `MissingClientTokenError`, for the `M_UNKNOWN_TOKEN` and `M_MISSING_TOKEN`
cases respectively - and an `InvalidClientCredentialsError` base class for the
two of them.
This fixes a bug which were causing the "event_format" field to be
ignored in the filter of requests to the `/messages` endpoint of the
CS API.

This commit adds two config options:
* `restrict_public_rooms_to_local_users`
Requires auth to fetch the public rooms directory through the CS API and disables fetching it through the federation API.
* `require_auth_for_profile_requests`
When set to `true`, requires that requests to `/profile` over the CS API are authenticated, and only returns the user's profile if the requester shares a room with the profile's owner, as per MSC1301.
MSC1301 also specifies a behaviour for federation (only returning the profile if the server asking for it shares a room with the profile's owner), but that's currently really non-trivial to do in a not too expensive way. Next step is writing down a MSC that allows a HS to specify which user sent the profile query. In this implementation, Synapse won't send a profile query over federation if it doesn't believe it already shares a room with the profile's owner, though.
Groups have been intentionally omitted from this commit.
Currently when fetching state groups from the data store we make two
hits two the database: once for members and once for non-members (unless
request is filtered to one or the other). This adds needless load to the
datbase, so this PR refactors the lookup to make only a single database
hit.
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.
parse_integer and parse_string can take a request and raise errors
in case we have wrong or missing params.
This PR tries to use them more to deduplicate some code and make it
better readable
Turns out that there is a valid usecase for retrieving event by id (notably
having received a push), but event ids should be scoped to room, so /event/{id}
is wrong.
The _get_joined_users_from_context cache stores a mapping from user_id
to avatar_url and display_name. Instead of storing those in a dict,
store them in a namedtuple as that uses much less memory.
We also try converting the string to ascii to further reduce the size.
We somehow specced APIs with reason strings, preserve the content
in the events and even have the clients display them, but failed
to actually pass the parameter through to the event content.
This returns the currently joined members in the room with their display
names and avatar urls. This is more efficient than /members for large
rooms where you don't need the full events.
This fixes a race whereby:
- User hits an endpoint.
- No cached transaction so executes main code.
- User hits same endpoint.
- No cache transaction so executes main code.
- Main code finishes executing and caches response and returns.
- Main code finishes executing and caches response and returns.
This race is common in the wild when Synapse is struggling under load.
This commit fixes the race by:
- User hits an endpoint.
- Caches the promise to execute the main code and executes main code.
- User hits same endpoint.
- Yields on the same promise as the first request.
- Main code finishes executing and returns, unblocking both requests.
It was always intended to allow custom keys on the join event, but this has
at some point been lost. Restore it.
If the user specifies keys like "avatar_url" then they will be clobbered.
hs.get_handlers() can not be invoked from split out processes. Moving
the invocations down a level means that we can slowly split out
individual servlets.
