uvloop
|
|
|
|
|
======
|
|
|
|
|
|
|
|
|
|
`uvloop` is a fast, drop-in replacement of the built-in asyncio event loop.
|
|
|
|
|
`uvloop` is released under the MIT license.

|
|
|
`uvloop` and asyncio, combined with the power of async/await in Python 3.7,
|
2016-05-08 04:30:27 +00:00
|
|
|
makes it easier than ever to write high-performance networking code in Python.
|
|
|
|
|
|
|
|
|
|
`uvloop` makes asyncio fast. In fact, it is at least 2x faster than nodejs,
|
|
|
|
|
gevent, as well as any other Python asynchronous framework. The performance of
|
|
|
|
|
uvloop-based asyncio is close to that of Go programs.

Architecture
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
The asyncio module, introduced by PEP 3156, is a collection of network
|
|
|
|
|
transports, protocols, and streams abstractions, with a pluggable event loop.
|
|
|
|
|
The event loop is the heart of asyncio. It provides APIs for:
|
|
|
|
|
|
|
|
|
|
- scheduling calls,
|
|
|
|
|
- transmitting data over the network,
|
|
|
|
|
- performing DNS queries,
|
|
|
|
|
- handling OS signals,
|
|
|
|
|
- convenient abstractions to create servers and connections,
|
|
|
|
|
- working with subprocesses asynchronously.
|
|
|
|
|
|
|
|
|
|
`uvloop` implements the :class:`asyncio.AbstractEventLoop` interface which
|
|
|
|
|
means that it provides a drop-in replacement of the asyncio event loop.
|
|
|
|
|
|
|
|
|
|
`uvloop` is written in Cython and is built on top of libuv.
|
|
|
|
|
|
|
|
|
|
libuv is a high performance, multiplatform asynchronous I/O library used by
|
|
|
|
|
nodejs. Because of how wide-spread and popular nodejs is, libuv is fast and
|
|
|
|
|
stable.
|
|
|
|
|
|
|
|
|
|
`uvloop` implements all asyncio event loop APIs. High-level Python objects
|
|
|
|
|
wrap low-level libuv structs and functions. Inheritance is used to keep the
|
|
|
|
|
code DRY and ensure that any manual memory management is in sync with libuv
|
|
|
|
|
primitives' lifespans.
