For the most part, Motor relies on the calls to the underlying PyMongo functions to raise DeprecationWarnings. Since these synchronous calls are run using a thread pool executor, the application must be run using -Wdefault in order to make the warning user-visible. For example:
$ # test script
$ cat sample.py
import asyncio
from motor.motor_asyncio import AsyncIOMotorClient
async def main():
client = AsyncIOMotorClient()
print(await client.admin.command('ping'))
print(client.nodes)
await client.fsync()
asyncio.run(main())
$
$ # running without -W
$ python sample.py
{'ok': 1.0}
frozenset({('localhost', 27017)})
$
$ # running it with -W
$ python -Wdefault sample.py
{'ok': 1.0}
frozenset({('localhost', 27017)})
/Users/pmital/.pyenv/versions/3.7.5/lib/python3.7/concurrent/futures/thread.py:57: DeprecationWarning: fsync is deprecated. Use client.admin.command('fsync') instead.
result = self.fn(*self.args, **self.kwargs)
We should come up with a better way to raise these warnings so that applications don't need to change their invocation to see them.
