Dear Juan Carlos:
I'm a high school teacher and I teach java. First I want to let you know that I LOVE 😍 VPL! This is the best tool for teaching computer science and you have built in so many features to make grading quick and easy. The students engage so much more when test cases are provided. This is an AWESOME tool and thank you for providing it free!
I pay for moodle hosting. VPL writes data files and directories to /repository/moodledata/vpl_data/. Three times over the past 18 months, directories from vpl_data have gone missing. The only reason I know this is because I will go back to a previous VPL assignment and find that data is missing: NO test cases; NO required files; and NO user files -- all the .java files are gone! So I contacted the host and they found a server backup. I replaced the directories and all the VPL assignments worked again.
QUESTION: Have you heard of this happening to anyone? Do you think the hosting company system is removing the vpl_data directories? Do you think it is when the Moodle version is upgraded? Do you have a suggestion of how to prevent this from happening?
Thank you for any advice or information you have!
