      1. To simulate a slow connection I suggest using Chrome and turning on throttling in the Developer Tools.
      2. Create an assignment.
      3. Submit multiple large files as the students. Be sure they are large enough that the throttled download will take more than 30 seconds.
      4. As the teacher try to Download all submissions.
        The download will error with a PHP timeout.

      If enough data was uploaded to the assignment the timeout may occur durring the compressing of the files into a zip. see MDL-40245

      add a call to core_php_time_limit::raise(); before sending the temporary file.

      Description

      If an assignment has a lot of large files in it. Download all submissions may take longer than the default 30 second php script time limit. This makes the download fail.
