This commit fixes two bugs to do with decorators not instrumenting `ReplicationEndpoint`'s `send_request` correctly. There are two decorators on `send_request`: Prometheus' `Gauge.track_inprogress()` and Synapse's `opentracing.trace`. `Gauge.track_inprogress()` does not have any support for async functions when used as a decorator. Since async functions behave like regular functions that return coroutines, only the creation of the coroutine was covered by the metric and none of the actual body of `send_request`. `Gauge.track_inprogress()` returns a regular, non-async function wrapping `send_request`, which is the source of the next bug. The `opentracing.trace` decorator would normally handle async functions correctly, but since the wrapped `send_request` is a non-async function, the decorator ends up suffering from the same issue as `Gauge.track_inprogress()`: the opentracing span only measures the creation of the coroutine and none of the actual function body. Using `Gauge.track_inprogress()` as a context manager instead of a decorator resolves both bugs. |
