Python 3.7 "TCP echo server using streams" sample code does not work with uvloop. #221
Description
- uvloop version: 0.12.0
- Python version: 3.7.1
- Platform: Linux
- Can you reproduce the bug with
PYTHONASYNCIODEBUGin env?: not tested
Running the following code (source: https://docs.python.org/3/library/asyncio-stream.html#tcp-echo-server-using-streams) with uvloop:
import asyncio
import uvloop
import sys
async def handle_echo(reader, writer):
data = await reader.read(100)
message = data.decode()
addr = writer.get_extra_info('peername')
print(f"Received {message!r} from {addr!r}")
print(f"Send: {message!r}")
writer.write(data)
await writer.drain()
print("Close the connection")
writer.close()
async def main():
server = await asyncio.start_server(handle_echo, '127.0.0.1', 8888)
addr = server.sockets[0].getsockname()
print(f'Serving on {addr}')
async with server:
await server.serve_forever()
uvloop.install()
print("python version:", sys.version)
print("uvloop version:", uvloop.__version__)
asyncio.run(main())Produces the following error message:
