* Allow specific pollers to be wokenGravatar Craig Tiller2015-07-29
| | | | | | | | | | | | | | | | | | | Currently, if two threads call grpc_completion_queue_pluck on the same completion queue for different tags, there is a 50% chance that we deliver the completion wakeup to the wrong poller - forcing the correct poller to wait until its polling times out before it can return an event up to the application. This change tweaks our polling interfaces so that we can indeed wake a specific poller. Nothing has been performance tuned yet. It's definitely sub-optimal in a number of places. Wakeup file-descriptors should be recycled. We should have a path that avoids calling poll() followed by epoll(). We can probably live without it right at the second though. This code will fail on Windows at least (I'll do that port when I'm in the office and have a Windows machine).

* Fix a TSAN reported raceGravatar Craig Tiller2015-07-01
| | | | | close() could race with epoll_ctl(); pretend to be polling while adding to the epoll set to prevent this
* Remove return status from maybe_work.Gravatar Craig Tiller2015-06-22
| | | | | | | Since alarm checks may mutate work deadlines for pollsets, the value returned from maybe_work is meaningless. Instead, maybe pollset_work always return 1 if maybe_work is invoked, and then redo the deadline check _on the next call_ to pollset_work.

* Epoll based multipollerGravatar David Klempner2015-02-10
This is a multipoller based on epoll rather than poll. Note that this implementation is aimed at correctness rather than performance, although it should immediately have better scalability to large numbers of FDs, both due to epoll's O(1) sized API and due to not needing to wake up polling threads to do interest set changes. One notable difference here is that we directly attach a wakeup fd rather than using the freelisting kick mechanism that the poll() based implementations use, because modifying the epoll set to use a different kick fd each time isn't free.
