Hi, I just released Trollius 0.1.5: https://pypi.python.org/pypi/trollius
It is synchronized with Tulip 0.3.1 and the asyncio module of Python 3.4 rc1. Changes between Trollius 0.1.4 and 0.1.5: - Merge with Tulip 0.3.1: * New asyncio.subprocess module * _UnixWritePipeTransport now also supports character devices, as _UnixReadPipeTransport. Patch written by Jonathan Slenders. * StreamReader.readexactly() now raises an IncompleteReadError if the end of stream is reached before we received enough bytes, instead of returning less bytes than requested. * poll and epoll selectors now round the timeout away from zero (instead of rounding towards zero) to fix a performance issue * asyncio.queue: Empty renamed to QueueEmpty, Full to QueueFull * _fatal_error() of _UnixWritePipeTransport and _ProactorBasePipeTransport don't log BrokenPipeError nor ConnectionResetError * Future.set_exception(exc) now instanciate exc if it is a class * streams.StreamReader: Use bytearray instead of deque of bytes for internal buffer - Fix test_wait_for() unit test Victor
