Bug description:
We have identified a regression starting with Python 3.10 when making a large request over TLS.
import requests
requests .post ('https://google.com' , data = b'A' * 1000000 )
urllib3 .exceptions .SSLError : EOF occurred in violation of protocol (_ssl .c :2426 )
The above exception was the direct cause of the following exception :
Traceback (most recent call last ):
File "/usr/local/lib/python3.10/site-packages/requests/adapters.py" , line 486 , in send
resp = conn .urlopen (
File "/usr/local/lib/python3.10/site-packages/urllib3/connectionpool.py" , line 844 , in urlopen
retries = retries .increment (
File "/usr/local/lib/python3.10/site-packages/urllib3/util/retry.py" , line 515 , in increment
raise MaxRetryError (_pool , url , reason ) from reason # type: ignore[arg-type]
urllib3 .exceptions .MaxRetryError : HTTPSConnectionPool (host = 'google.com' , port = 443 ): Max retries exceeded with url : / (Caused by SSLError (SSLEOFError (8 , 'EOF occurred in violation of protocol (_ssl.c:2426)' )))
During handling of the above exception , another exception occurred :
Traceback (most recent call last ):
File "<stdin>" , line 1 , in < module >
File "/usr/local/lib/python3.10/site-packages/requests/api.py" , line 115 , in post
return request ("post" , url , data = data , json = json , ** kwargs )
File "/usr/local/lib/python3.10/site-packages/requests/api.py" , line 59 , in request
return session .request (method = method , url = url , ** kwargs )
File "/usr/local/lib/python3.10/site-packages/requests/sessions.py" , line 589 , in request
resp = self .send (prep , ** send_kwargs )
File "/usr/local/lib/python3.10/site-packages/requests/sessions.py" , line 703 , in send
r = adapter .send (request , ** kwargs )
File "/usr/local/lib/python3.10/site-packages/requests/adapters.py" , line 517 , in send
raise SSLError (e , request = request )
requests .exceptions .SSLError : HTTPSConnectionPool (host = 'google.com' , port = 443 ): Max retries exceeded with url : / (Caused by SSLError (SSLEOFError (8 , 'EOF occurred in violation of protocol (_ssl.c:2426)' )))
The same request works fine on Python 3.9.
