Since the signal handler can be called in any thread of the application, it may happen so in a non-D thread where Thread.getThis() returns null. This change works around this and also removes the need to call SpinLock.setup on thread startup.
This change modifies destructors to anticipate that they can be called form a foreign thread if the GC is involved. The actual release of the reference will then happen deferred in the original thread.
- Copying LocalManualEvent now works correctly, using reference counting
- ManualEvent correctly pins the reference to the thread-local waiter until it has finished emitting it
- ThreadLocalWaiter uses a doubly-linked list to manage task waiters (more efficient deletion, FIFO trigger order)
- Fixed a bug in ThreadLocalWaiter.emit() where the head element of the iterated list might already have stopped waiting, resulting in an invocation of a dangling TaskWaiter pointer
This will have to be adjusted to use a circular list with the possibility to insert a pivot element, so that consumption of waiters is safe in all cases (see the comment at 1265).
- asyncAwaitAny now takes the callback type, so that parameter storage classes are handled correctly
- Implement TCPConnection.remoteAddress/localAddress
- Implement TCPConnection.tcpNoDelay, keepAlive and readTimeout
- Implement timeout handling for TCPConnection.waitForData
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.
- 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
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 The API is still mostly compatible with mainline vibe.d, but the driver systen has been replaced by the eventcore library and sockets/files/timers/...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.
