Add yieldLock(), which enables enforcing no task switches within a scope.
runTask() was altered to delay the task switch in case it gets called within an active yieldLock(), so that running tasks is still possible.

Partially implement FileDescriptorStream.
Currently only works for waiting on read-readiness (eventcore is not exposing an analog function for write-readiness).

Limit the number of recycled fibers.
This allows the process to free up memory after heavy load spikes, while not impacting performance negatively.

Fix createTimer() when called with a callback. 2017-01-30 19:55:34 +01:00

Handle Timer.stop() gracefully for null timers. 2017-01-30 17:34:25 +01:00

Add compatibility overload for setTimer(). 2017-01-29 16:46:21 +01:00
Sönke Ludwig fc96ee9050
Fixes for setTimer and SpinLock.
- setTimer now starts a task to call the callback. This keeps the timer referenced and avoids issues if I/O functions are called from within the callback.
- SpinLock is now also initialized in "shared static this", so that applications using "shared static this" for initialization work properly.

Sönke Ludwig fdfbb55aa8 Re-implement ManualEvent.
This simplifies the logic by separating thread local notifications from cross-thread notifications, as well as replacing lockless operations by a spin lock. The thread local variant of ManualEvent is now also separated into a LocalManualEvent type.

Sönke Ludwig e28c6950d7 Fix shutdown behavior.
- Detection of the main thread contained a race condition
- The exit flag monitor task that is started for each event loop wasn't shut down, so that many could be running if runEventLoop was called multiple times.

Sönke Ludwig 8c0660781d Thread safety improvements in the task system.
Removes some invalid safety annotations and adds a workaround for a starvation issue in Task.join() across threads boundaries. This is still not thread-safe, but now has a safety-net and is documented, so that it doesn't get lost.

Sönke Ludwig bf2edc7fb2 Fix TaskScheduler.waitAndProcess to not block if any tasks were resumed.
In situations where no events were involved in an multi-task scenario, the old behavior could lead to the process to starve or hang until an event arrived.

Sönke Ludwig ed36531bd2 Add runEventLoopOnce() and fix hibernate() to block outside of a task. 2016-06-16 10:44:55 +02:00
Sönke Ludwig 8264070f19 Fix for latest eventcore changes. 2016-06-14 09:25:28 +02:00
Sönke Ludwig 3b0e4e0452 Big refactoring step.
- Moves a lot of stuff from vibe.core.core to vibe.core.task
- Introduces TaskScheduler to unify the scheduling process
- Refines how tasks are scheduled and processed (can push to the front of the task queue and uses a marker task to keep track of the spot up to which to process)
- Start to add proper support for task interrupts and timeouts by properly cancelling in-flight async operations
- Work on ManualEvent - still not functional for the shared case
- Implement proper IP address parsing in NetworkAddress

Sönke Ludwig 8f4222916f Weaken the task double-resumption assertion condition.
This assertion got triggered in a number of harmless situations and it's not always easy to avoid. Trying to avoid it, it has already caused a rather bad task starvation bug (#1441), so at this point it seems to be better to get rid of it.

See also #1407

Sönke Ludwig 3a6583b375 Explictly avoid double-resumption of tasks during Libevent2TCPConnection.close().
The previous fix for #1376 resulted in a possible task starvation when the peer reset the connection before the outbound buffer was drained. The new approach now always resumes the waiting task exactly once, no matter how many events happen and no matter in which order.

Sönke Ludwig 7e2d1dd038 Initial commit.
The library is able to support simple TCP servers in the current state. The API is still mostly compatible with mainline vibe.d, but the driver systen has been replaced by the eventcore library and sockets/files/timers/... are now structs with automatic reference counting instead of GC collected classes. The stream interfaces have been removed for now.
