Description Jon McKenzie 2022-04-07 19:53:34 UTC
Description of problem:

Tools using the 'python-requests' package and 'python-boto3' package (which has 'python-s3transfer' as a dependency) together break with this latest version with a Python ImportError


Version-Release number of selected component (if applicable):

0.1.13-1.el7_9.2


How reproducible: Always


Steps to Reproduce:
1. Install python-requests and python-boto3 (with python-s3transfer 0.1.13-1.el7_9.2 as dependency)
2. Open a Python REPL and run 'import requests' and then 'import boto3'. Observe the ImportError exception
3. Open a brand new Python REPL and run just 'import boto3'. No import exception occurs.
4. Downgrade python-s3transfer to 0.1.13-1.el7.0.1 and run either the steps from #2 or #3 above. No import error occurs.

Actual results:

```
>>> import requests
>>> import boto3

  File "/usr/lib/fence-agents/bundled/botocore/httpsession.py", line 10, in <module>
    from urllib3.util.ssl_ import (

```

Expected results:

```
>>> import requests
>>> import boto3
>>>
```
