7 years ago Do you mean to do this?
from hyper import HTTP20Connection, HTTPConnection, compat, tls
import socket
host = "devhost"
port = 443
ssl_context = tls.init_context()
ssl_context.check_hostname = False
ssl_context.verify_mode = ssl.CERT_NONE
conn = HTTPConnection(host=host, port=port, ssl_context=ssl_context, secure=True )
###### do hack
socket.setdefaulttimeout(30)
sock = socket.create_connection((host, port))
conn._sock = sock
######
conn.request( 'GET', "/mypath )
resp = conn.get_response()
There's no need for the patching. A call to socket.setdefaulttimeout() immediately after the imports, but before you create a HTTPConnection, will be totally sufficient.

7 years ago I set the socket.setdefaulttimeout(30) before import HTTPConnection. And print the variable t , the t value is 30.
###
import socket
socket.setdefaulttimeout(30)
t = socket.getdefaulttimeout()
print(t)

from hyper import HTTPConnection,tls
host = "devhost"
port = 443
ssl_context = tls.init_context()
ssl_context.check_hostname = False
ssl_context.verify_mode = ssl.CERT_NONE
start = time.time()
try:
conn.request( 'GET', "/mypath" )
resp = conn.get_response()
temp_data = resp.read().decode('utf-8')
except Exception as e:
raise
finally:
print('time\t', time.time() - start)but agein raise exception socket.timeout: The read operation timed out again.
I print the request time, is the default 5 seconds.

socket.timeout: The read operation timed outI study the source connection.py ,
I hack edit the source line 123 sock = socket.create_connection((host, port), 5) to sock = socket.create_connection((host, port)) on my local, the request time out more than 5 seconds and not raise timeout now, my issue solved.
maybe this is the issue.

returnAh I see, you're timing out in the connection handshake. Yes, in that case you do need to make the monkeypatch in your original response to adjust the timeout on connection setup.
I have a long time request , more than 20 second. but it's raise time out error.
I study this document,but I don't know how to set time out .
who can help me?
