ResourceWarning: unclosed ssl.SSLSocket

For some reason I’m getting a ResourceWarning about a unclosed socket, even when I’m specifically closing the socket myself. See testcase below:

python3 -munittest discover

import sys
import boto3
import unittest

BUCKET = ''
KEY = ''


def give_it_to_me():
    client = boto3.client('s3')
    obj = client.get_object(Bucket=BUCKET, Key=KEY)
    try:
        yield from iter(lambda: obj['Body'].read(1024), b'')
    finally:
        print('Im closing it!', file=sys.stderr, flush=True)
        obj['Body'].close()


class TestSomeShit(unittest.TestCase):
    def test_it(self):
        res = give_it_to_me()
        for chunk in res:
            pass
        print('Done', file=sys.stderr, flush=True)

Fill in any BUCKET and KEY to see the problem. Attaching my output below:

Im closing it!
test.py:22: ResourceWarning: unclosed <ssl.SSLSocket fd=7, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('...', 55498), raddr=('...', 443)>
  for chunk in res:
Done

OK

So no fix? Warning is still important. boto3 developers are lazy.

Don’t use this kind of language, especially not on an open source project where the developers owe you nothing and you are getting their work for free.

If this issue is so important to you that you can’t wait for a fix to be submitted and merged in, then fork the project and fix it yourself, and spare us all this kind of low quality whining.
