Fixing warnings triggered by cURL when no response is received. #1438

merged 1 commit into from

This pull request resolves a situation where when no response from a server is received a PHP warning is thrown by the cURL transport. Instead the code triggering the warning is mitigated and additionally a check to see if there was any response data is added to validate a response was actually received or throw an exception.

Please take a look at my PR #1022.
This is addressing same issue across all JHttpTransports


Actually there's a difference between getting empty content and what you get from a bad url where in fact you are not going to get a normal repsonse code since there is no server.
$return = new JHttpResponse

I haven't tested it yet but I bet it isn't pretty if the $uri doesn't exist, it probably needs an exception and then JTransportCurl needs to handle that. And yes the error issue is a problem because php is going to send a notice before any exception gets thrown.

Needs to catch that
