This change modifies how the backpressure algorithm in bufferstream works - in particular, instead of working byte-by-byte, it will now work seq-by-seq. When data arrives, it usually does so in packets - in the current bufferstream, the packet is read then split into bytes which are fed one by one to the bufferstream. On the reading side, the bytes are popped of the bufferstream, again byte by byte, to satisfy `readOnce` requests - this introduces a lot of synchronization traffic because the checks for full buffer and for async event handling must be done for every byte. In this PR, a queue of length 1 is used instead - this means there will at most exist one "packet" in `pushTo`, one in the queue and one in the slush buffer that is used to store incomplete reads. * avoid byte-by-byte copy to buffer, with synchronization in-between * reuse AsyncQueue synchronization logic instead of rolling own * avoid writeHandler callback - implement `write` method instead * simplify EOF signalling by only setting EOF flag in queue reader (and reset) * remove BufferStream pipes (unused) * fixes drainBuffer deadlock when drain is called from within read loop and thus blocks draining * fix lpchannel init order |
