WXME corrupted and cannot be open #537

Open wilbowma opened 2 years ago

wilbowma commented 2 years ago

We're not sure how this happened, but a student managed to get their file corrupted, and we can no longer open it in DrRacket. DrRacket reports the following error.

This error is quite severe as, because it's a WXME file, they cannot recover any of their progress. Thankfully this is a practice problems, but it could be a real problem if it happens on an assessment.

I've uploaded the file here (with the fake .txt extension to circumvent GitHub issues): 2019W1-F-starter.rkt.txt

The error is reproducible in 8.3.0.10 [cs], and 8.1 BC.

There was an error loading ..../Downloads/2019W1-F-starter.rkt.

How did they do this? (Not about blame but I’m interested in what triggered the corruption)

wilbowma commented 2 years ago

Unfortunately, I don’t know, and can’t get any details from the student.

I'm not sure this is helpful, but this file looks truncated. It also is the case that if I save a valid file and then use emacs to remove the end of it, I get the same error message.
