Merge pull request #3138 from matrix-org/rav/catch_unhandled_exceptions 
Improve exception handling for background processes
 2018-04-27 11:47:49 +01:00

605defb9e4 Add missing consumeErrors 
In general we want defer.gatherResults to consumeErrors, rather than having
exceptions hanging around and getting logged as CRITICAL unhandled errors.

9255a6cb17 Improve exception handling for background processes 
There were a bunch of places where we fire off a process to happen in the
background, but don't have any exception handling on it - instead relying on
the unhandled error being logged when the relevent deferred gets
garbage-collected.

This is unsatisfactory for a number of reasons:
 - logging on garbage collection is best-effort and may happen some time after
   the error, if at all
 - it can be hard to figure out where the error actually happened.
 - it is logged as a scary CRITICAL error which (a) I always forget to grep for
   and (b) it's not really CRITICAL if a background process we don't care about
   fails.

So this is an attempt to add exception handling to everything we fire off into
the background.

b1dfbc3c40 Refactor store.have_events 
It turns out that most of the time we were calling have_events, we were only
using half of the result. Replace have_events with have_seen_events and
get_rejection_reasons, so that we can see what's going on a bit more clearly.

639480e14a Avoid creating events with huge numbers of prev_events 
In most cases, we limit the number of prev_events for a given event to 10
events. This fixes a particular code path which created events with huge
numbers of prev_events.

b78395b7fe Refactor ResponseCache usage 
Adds a `.wrap` method to ResponseCache which wraps up the boilerplate of a
(get, set) pair, and then use it throughout the codebase.

This will be largely non-functional, but does include the following functional
changes:

* federation_server.on_context_state_request: drops use of _server_linearizer
  which looked redundant and could cause incorrect cache misses by yielding
  between the get and the set.
* RoomListHandler.get_remote_public_room_list(): fixes logcontext leaks
* the wrap function includes some logging. I'm hoping this won't be too noisy
  on production.

eb8d8d6f57 Use join_policy API instead of joinable 
The API is now under
 /groups/$group_id/setting/m.join_policy

and expects a JSON blob of the shape

```json
{
  "m.join_policy": {
    "type": "invite"
  }
}
```

where "invite" could alternatively be "open".

91ea0202e6 move handling of auto_join_rooms to RegisterHandler 
Currently the handling of auto_join_rooms only works when a user
registers itself via public register api. Registrations via
registration_shared_secret and ModuleApi do not work

This auto_joins the users in the registration handler which enables
the auto join feature for all 3 registration paths.

This is related to issue #2725
