| | | | | | | | Update some code based on that documentation
| * More scalable unary pollingGravatar Craig Tiller2015-05-14
| | | | | | | | | | | | - admit only one poller for read and one for write at a time (poll is level triggered, so this avoids a thundering herd on each event) - wake only one poller when more pollers are needed, again avoiding a thundering herd

* Add a no_barrier_load atomic operation.Gravatar David Klempner2015-03-11
| | | | | Use this to relax the acq_loads in some fd_posix assertions. The primary goal here is to avoid masking potential iomgr races from tsan.
* Move close() to when the fd refcount goes to zeroGravatar David Klempner2015-02-24
| | | | | | Instead, we do a shutdown() at the point we are currently closing, to kick off socket teardown while ensuring an fd ref is sufficient to make concurrent syscalls like epoll_ctl safe.

| * Fix a TSAN reported errorGravatar Craig Tiller2015-02-18
|/ | | | | | | | | | We now pass down pointers to closures instead of (callback, arg) pair elements separately. This allows us to store one word atomically, fixing a race condition. All call sites have been updated to the new API. No new allocations are incurred. grpc_fd_state is deleted to avoid any temptation to ever add anything there again.

|
* Reduce contention on lockGravatar Craig Tiller2015-02-09
| | | | Change the fd watcher from being O(active_pollers) to O(1), reducing time spent under the fd->watcher_mu lock, and ultimately scaling us much better.
* Freelist grpc_fd objectsGravatar David Klempner2015-01-28
| | | | | This is necessary for efficient implementations where multiple threads simultaneously sit in epoll_wait and the like on the same pollset.
* Disable compilation of some filesGravatar Craig Tiller2015-01-21
| | | | They're not needed on Windows
* Remove libevent.Gravatar ctiller2015-01-09
| | | | | | | | | | | | | | | | | | | | | | | Fixed any exposed bugs across the stack. Add a poll() based implementation. Heavily leverages pollset infrastructure to allow small polls to be the norm. Exposes a mechanism to plug in epoll/kqueue for platforms where we have them. Simplify iomgr callbacks to return one bit of success or failure (instead of the multi valued result that was mostly unused previously). This will ease the burden on new implementations, and the previous system provided no real value anyway. Removed timeouts on endpoint read/write routines. This simplifies porting burden by providing a more orthogonal interface, and the functionality can always be replicated when desired by using an alarm combined with endpoint_shutdown. I'm fairly certain we ended up with this interface because it was convenient to do from libevent. Things that need attention still: - adding an fd to a pollset is O(n^2) - but this is probably ok given that we'll not use this for multipolling once platform specific implementations are added. - we rely on the backup poller too often - especially for SSL handshakes and for client connection establishment we should have a better mechanism ([] [] - Linux needs to use epoll for multiple fds, FreeBSD variants (including Darwin) need to use kqueue. ([] [] - Linux needs to use eventfd for poll kicking.
