Description Stefan Meyer 2023-04-17 11:56:26 UTC

Description of problem:
Pulp download of package fails silently if a proxy uses "data trickling" and later fails

Version-Release number of selected component (if applicable):
- Satellite 6.12
- python39-pulpcore-3.18.16-1.el8pc.noarch

How reproducible:
- A web proxy (example: McAfee Web Gateway) uses "data trickling" to keep a session open for Pulp
  and downloads the package to scan it for viruses. 
- If everything is ok, the proxy then lets the whole file through.
- If the package is however blocked on the web proxy the proxy prints an error messages to the end 
  of the file and then closes the connection
- If that happens pulp only reports the error message "Response payload is not completed" without
  showing exactly which package failed to download

Actual results:
- Error message "Response payload is not completed" without further information which package failed to download

Expected results:
- Pulp should show the full URL of the failed package and the complete error message provided by the upstream proxy
