Requesting Python 3.10 Upgrade for QuARC Lambda Environment Due to TLS 1.3 Support

[rajeshpandey2053]

Describe the bug
QuARC currently relies on Lambda for deployment, utilizing Python 3.8 as the runtime environment. However, pyQuARC dependencies are also tied to Python 3.8.

We've encountered an issue stemming from the older version of OpenSSL installed in the Python 3.8 runtime environment, which results in errors when making requests to certain web endpoints.

To mitigate this, we propose upgrading the Python runtime environment to version 3.10.

To Reproduce
Steps to reproduce the behavior:

1. Go to AWS lambda and set the runtime as Python 3.8
2. Run the following code in the handler.py

import requests
url = "https://www.atmosp.physics.utoronto.ca/MOPITT/home.html"
response=requests.get(url, headers=headers, timeout=10).status_code
print(response)

4. See the error as follows
   { "errorMessage": "HTTPSConnectionPool(host='www.atmosp.physics.utoronto.ca', port=443): Max retries exceeded with url: /MOPITT/home.html (Caused by SSLError(SSLError(1, '[SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:1131)')))", "errorType": "SSLError", "stackTrace": [ " File \"/var/task/lambda_function.py\", line 132, in lambda_handler\n \"body\": json.dumps(requests.get(url).text),\n", " File \"/var/task/requests/api.py\", line 76, in get\n return request('get', url, params=params, **kwargs)\n", " File \"/var/task/requests/api.py\", line 61, in request\n return session.request(method=method, url=url, **kwargs)\n", " File \"/var/task/requests/sessions.py\", line 530, in request\n resp = self.send(prep, **send_kwargs)\n", " File \"/var/task/requests/sessions.py\", line 643, in send\n r = adapter.send(request, **kwargs)\n", " File \"/var/task/requests/adapters.py\", line 514, in send\n raise SSLError(e, request=request)\n" ] }

Expected behavior
Upgrading the Python runtime environment to 3.10 should align the dependencies across QuARC and Lambda, resolving the OpenSSL version discrepancy and ensuring smooth operation when making web requests.

Additional context

• QuARC relies on Lambda deployment for its infrastructure.
• pyQuARC dependencies are designed for Python 3.8.
• The discrepancy between Python versions is causing issues with OpenSSL versions, leading to errors in web requests.
• Python 3.10, with its use of the latest OpenSSL version (2023), offers TLS 1.3 support, addressing our current limitations.
• To verify the OpenSSL version used by Python, execute the following code:

 import ssl
print(ssl.OPENSSL_VERSION)
