To Reproduce

1. Create a callback.
2. Use it in the configuration file.
3. Run the program and stop it with Ctrl+C.

Expected Behavior

The on_run_end and on_job_end callbacks should be executed when the program is stopped by a keyboard interrupt.

Hi @kamo-sevoyan-lc ,

I wanted to share that I have tested this issue on Hydra v1.3.2. I was able to reproduce the problem where on_run_end and on_job_end callbacks are not triggered on a KeyboardInterrupt.

I have applied a fix in my forked version by updating run_job() in hydra/core/utils.py to catch KeyboardInterrupt and call the callbacks safely. After the change, the callbacks are correctly executed when stopping the program with Ctrl+C.

I can provide a PR if the maintainers are open to merging this fix.

Here’s a summary of the change:

• Added a KeyboardInterrupt handler around the task execution.
• Called callbacks.on_job_end() and callbacks.on_run_end() in that handler.
• Re-raised the interrupt so the job still terminates normally.

This ensures that any cleanup or logging callbacks run even when the program is interrupted manually.
