Classification:

Crash / locks up

Reproducibility:

Always

Summary

We don't seem to do any validation on the user's input for regex matching. The app then doesn't gracefully handle a regex string which Python re doesn't parse.

Steps to Reproduce (if applicable)

1. Enter a malformed regex for a phrase, like the single character, *.
2. Attempt to save this change.
3. Try to trigger the phrase.

Expected Results

Good: The app shouldn't crash.
Better: It should trap and output re errors somewhere.
Best: the app should validate the user input by attempting an re compile when a user provides a regex. If it fails, then the regex won't be saved.

Actual Results

The app progressively locks up, and the UI needs to be killed. The server then crashes.

Notes

I think this would be a good first PR for me to work on.
