Improve performance of accepting incoming connections.
- Removes the accept() loop, as that doesn't measurably improve performance in practice. This also gives each connection the possibility to perform initial I/O before more concurrency is generated by accepting the next connection.

- Uses SOCK_NONBLOCK in conjunction with socket() and accept4() to save one additional syscall per connection.

Use level-triggered events for listening stream sockets.
The limit of 20 accepted connections per event invocation can otherwise lead to no more connections being accepted when more that 20 connections are available at a time. This is an adaptation of @Boris-Barboris pull request #21 to restrict the level triggered behavior to listening sockets. See also #20.

Sönke Ludwig eb595ef858 Fix always calling GC.addRange in ChoppedVector if necessary. 2017-08-26 22:33:00 +02:00
Sönke Ludwig 74352a9ac5 Avoid dangling socket slot access in the WinAPI driver.
When the last reference got released while a blocking socket operation was still in progress, the old slot was still accessed from the completion callback, leading to null pointer accesses or other issues.

Sönke Ludwig a63907b9f7
Fix multiple bugs in ThreadedFileEventDriver.
- Errors were reported as "ok"
- The cancel state logic was flawed and could lose cancel requests
- Operations could be removed from the active sets before they actually finished, causing the callback to never get called

Sönke Ludwig a7e5b49943 Implement basic UDP support for the WinAPI driver.
Note that the IOMode.immediate semantics are not compatible with the current 0-udp.d test and will instead call the callback asynchronously. It appears that non-blocking semantics are generally not possible with overlapped sockets.

Sönke Ludwig a263637bd3 Fix WSASend/WSARecv usage w.r.t. WSABUF parameter.
The documentation states that the buffer must be kept alive during the whole operation, so using a stack allocated buffer is illegal.

Sönke Ludwig ab796477e2 Move .userData to the socket driver.
Generally each FD type should have its own .userData property in the respective driver. This is important for drivers that don't have a unified file descriptor space and need to store user data in a type specific way.

Fix out of order processing issue with the TCP connection callback.
It could happen that the socket FD got reused before the connection callback was cleared. This in turn could result in the new connection callback to get overwritten with null.
