2018-05-02Fix a couple of logcontext leaks in unit testsRichard van der Hoff2-3/+9
... which were making other, innocent, tests, fail. Plus remove a spurious unittest.DEBUG which was making the output noisy.
2018-05-02Fix a class of logcontext leaksRichard van der Hoff2-33/+94
So, it turns out that if you have a first `Deferred` `D1`, you can add a callback which returns another `Deferred` `D2`, and `D2` must then complete before any further callbacks on `D1` will execute (and later callbacks on `D1` get the *result* of `D2` rather than `D2` itself). So, `D1` might have `called=True` (as in, it has started running its callbacks), but any new callbacks added to `D1` won't get run until `D2` completes - so if you `yield D1` in an `inlineCallbacks` function, your `yield` will 'block'. In conclusion: some of our assumptions in `logcontext` were invalid. We need to make sure that we don't optimise out the logcontext juggling when this situation happens. Fortunately, it is easy to detect by checking `D1.paused`.

2018-04-30Burminate v1authAdrian Tschira7-25/+24
This closes #2602 v1auth was created to account for the differences in status code between the v1 and v2_alpha revisions of the protocol (401 vs 403 for invalid tokens). However since those protocols were merged, this makes the r0 version/endpoint internally inconsistent, and violates the specification for the r0 endpoint. This might break clients that rely on this inconsistency with the specification. This is said to affect the legacy angular reference client. However, I feel that restoring parity with the spec is more important. Either way, it is critical to inform developers about this change, in case they rely on the illegal behaviour.

2018-04-27Use run_in_background in preference to preserve_fnRichard van der Hoff22-71/+97
While I was going through uses of preserve_fn for other PRs, I converted places which only use the wrapped function once to use run_in_background, to avoid creating the function object.

2018-04-27reraise exceptions more carefullyRichard van der Hoff2-13/+24
We need to be careful (under python 2, at least) that when we reraise an exception after doing some error handling, we actually reraise the original exception rather than anything that might have been raised (and handled) during the error handling.
2018-04-27Refactor event storage to not require stateErik Johnston1-37/+67
This is in preparation for using contexts that may or may not have the current_state_ids set. This will allow us to avoid unnecessarily pulling out state for an event on the master process when using workers. We also add a check to see if the state groups of the old extremities are the same as the new ones.
2018-04-27Add missing consumeErrorsRichard van der Hoff3-5/+9
In general we want defer.gatherResults to consumeErrors, rather than having exceptions hanging around and getting logged as CRITICAL unhandled errors.
2018-04-27Improve exception handling for background processesRichard van der Hoff20-237/+335
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.
