Aborting dvc exp run using CTRL-c can lead to apparent loss of recent script edits

[billtubbs]

Had a somewhat scary thing happen last night where I was editing and testing a dvc pipeline stage manually (python stages/my_stage.py) and then accidentally ran dvc exp run which I did not want to do, so I quickly pressed CTRL-c (possibly more than once).

Once it exited I realised my code was back to the state it was in at the previous git commit and I thought I had lost all my changes. Fortunately, I found them all in the stash

For other users having this problem here are the recovery steps:

git stash show
git stash pop

I tried googling this and couldn't find any other reports of this problem or the recovery steps.

My immediate problem is solved but my questions are

• How can this be avoided?
• Is there a better/safer way to abort a dvc run?
• Is the recovery step well known and if not can we make it easier to find, (e.g. in the documentation)?

Bill.
