we use eventlet in nova code base , at the beginning of each nova service
we monkey_patched standard libraries like:
import eventlet
from nova import debugger
if debugger.enabled():
# turn off thread patching to enable the remote debugger
eventlet.monkey_patch(os=False, thread=False)
else:
eventlet.monkey_patch(os=False)
I find an related comments about monkey_patch(os=False) from Cinder code:
if os.name == 'nt':
# eventlet monkey patching the os module causes subprocess.Popen to fail
# on Windows when using pipes due to missing non-blocking IO support.
eventlet.monkey_patch(os=False)
else:
eventlet.monkey_patch()
My question is : Is there any other reason we didn't monkey_patch os in Nova
