#515 pijul Crash Report: switching channels

Closed on December 7, 2021
fintohaps on August 16, 2021

The events that led up to this crash were:

  1. I wanted to unrecord a change, but it had dependencies so the command threw an error
  2. I forked a new channel to see if I could play with unrecording and reapplying changes
  3. When I tried to channel switch to the new channel it threw this error
  4. I was able to switch to main but now I can’t switch back to the channel I was working on.

I’d be interested if you can send a tarball of your .pijul to

pmeunier on August 16, 2021

Wait, it seems you’re using a rather old version of Pijul, and your bug looks like a corruption error. Several bugs have been found in Sanakirja since that version, I encourage you to try and reproduce with the latest version of Pijul.

I don’t think this issue exists anymore. Feel free to reopen if it still happens.
