Trollius provides infrastructure for writing single-threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related primitives. Here is a more detailed list of the package contents:
- a pluggable event loop with various system-specific implementations;
- transport and protocol abstractions (similar to those in Twisted);
- concrete support for TCP, UDP, SSL, subprocess pipes, delayed calls, and others (some may be system-dependent);
- a
Future
class that mimics the one in theconcurrent.futures
module, but adapted for use with the event loop; - coroutines and tasks based on generators (
yield
), to help write concurrent code in a sequential fashion; - cancellation support for
Future
s and coroutines; - synchronization primitives for use between coroutines in a single thread,
mimicking those in the
threading
module; - an interface for passing work off to a threadpool, for times when you absolutely, positively have to use a library that makes blocking I/O calls.
Trollius is a portage of the asyncio project (PEP 3156) on Python 2. Trollius works on Python 2.6-3.5. It has been tested on Windows, Linux, Mac OS X, FreeBSD and OpenIndiana.
