I need to create an asyncio implementation of an existent class, but I have to preserve the syncronous interface. In other words I have to put some wrappers around the coroutines to make them callable like normal blocking functions. I tried to do something like this:
class MyClass:
def __init__(self, loop, ...):
self._loop = loop
...
async def cor(...):
...
def method(...):
t = self._loop.create_task(self.cor(...))
while not t.done(): time.sleep(1)
return t.result()
However it doesn't work. The while hangs forever. I think the sleep call is blocking the event loop. I'm new to asyncio programming. How is this situation supposed to be handled?
