A PEP-3156 compatible event loop

aiouv: a PEP-3156 compatible event loop

Overview

PEP-3156 is a proposal for asynchronous I/O in Python, starting with Python 3.3. The reference implementation is codenamed Tulip and can be found here. It's part of the standard library in 3.4 and also available in PyPI under the name asyncio.

aiouv is an event loop implementation for asyncio based on pyuv.

Installation

aiouv depends on pyuv >= 1.0:

pip3 install -U pyuv

On Python 3.3, aiouv also requires asyncio >= 0.4.1:

pip3 install -U asyncio

Extra API functions

aiouv provides a few functions to create TCP, and UDP connections as well as cross platform named pipes support.

listen_tcp(loop, protocol_factory, addr)

Creates a TCP server listening in the specified address (IP / port tuple). On new connections a new TCPTransport will be created and a protocol will be created using the supplied factory.

Returns the listening handle.

connect_tcp(loop, protocol_factory, addr, bindaddr=None)

Create a TCP connection to the specified address. If bindaddr is specified, the local address is bound to it.

Returns a tuple with the created transport and protocol.

listen_pipe(loop, protocol_factory, name)

Creates a Pipe server listening in the specified pipe name. On new connections a new PipeTransport will be created and a protocol will be created using the supplied factory.

Returns the listening handle.

connect_pipe(loop, protocol_factory, name)

Create a Pipe connection to the specified pipe name.

Returns a tuple with the created transport and protocol.

create_udp_endpoint(loop, protocol_factory, local_addr=None, remote_addr=None)

Created a UDP endpoint. If local_addr is specified, the local interface will be bound to it. If remote_addr is specified, the remote target is set and it doesn't need to be specified when calling sendto().

Returns a tuple with the created transport and protocol.

Running the test suite

From the toplevel directory, run:

hg clone https://code.google.com/p/tulip/ asyncio
export PYTHONPATH=asyncio/
python runtests.py -v aiouv_events_test
