XDebug Only Uses Breakpoints on First Request

When### Issue Summary

While running Ubuntu + Local, I have encountered a frustrating quirk with XDebug that is really messing with me. My XDebug breakpoints will work perfectly fine until I happen to hit the “stop” button. When I do this, breakpoints completely stop on that site. I have tried stopping the server, restarting local, restarting my IDE, restarting the XDebug process, and none of them resolve the problem. The only way I can get my breakpoints to work again is by completely restarting my computer.

Troubleshooting Questions

  • Does this happen for all sites in Local, or just one in particular?
    This happens on all sites, regardless of if they’re using “preferred” or “custom”

  • Are you able to create a new, plain WordPress site in Local and access it in a Browser?
    Yes

Replication

To replicate:

  1. Create a new site
  2. Add a few breakpoints
  3. Open your IDE (I use PHPStorm) run the debugger
  4. Observe that the breakpoints work as-expected
  5. Hit “stop” before the request finishes.
  6. Try to run the debugger again.

System Details

  • Which version of Local is being used?
    5.9.4

  • What Operating System (OS) and OS version is being used?
    Ubuntu 20.04local-lightning.log (442.9 KB)

I haven’t tested this yet, but I suspect this is happening because XDebug needs to be updated to a newer version.

The author of Xdebug reached out on Twitter and mentioned that this was a problem that was resolved in a recent update.

The culprit appears to be this bug:
https://bugs.xdebug.org/1766

Im going to try updating XDebug to see if this fixes the issue.
