| Return of @asyncio.coroutine-wrapped coroutine object from @asyncio.coroutine-wrapped coroutine fails if asyncio debug is enabled. Consider following example: @asyncio.coroutine def outer_coro(): @asyncio.coroutine def inner_coro(): return 1 return g() result = loop.run_until_complete(outer_coro()) If debug is disabled result will be 1, if debug is enabled, result will be CoroWrapper object. This issue is discussed on asyncio mailing list: https://groups.google.com/forum/?fromgroups#!topic/python-tulip/YFfFxftxxDc Complete example to reproduce this problem is here: https://gist.github.com/rutsky/c72be2edeb1c8256d680 Attaching patch for Python 3.4 branch that fixes this issue and add test for this bug. This issue is not reproduced in Python 3.5, because CoroWrapper is awaitable in Python 3.5 (and in Python 3.4 CoroWrapper is not future or generator). | ||
