Save `pdb` Line History Between Runs

Feature or enhancement

Proposal:

When using pdb, it is possible to use the arrow keys (up/down) to navigate through previous commands. However, commands between runs are not preserved (unlike in the REPL).

I would like commands to be preserved between runs. For me, the most common use case for this is setting a breakpoint in the same place. Currently, I do this with python -m pdb -c "break file.py:line" ....

I am not familiar with how the pdb is implemented, but I have used bdb in depth in the past. I assume that it is possible to do this in a similar way to the REPL history. There is a workaround available here: https://stackoverflow.com/a/35390866/.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Commencez par retracer la manière dont pdb gère l’historique des commandes et comparez-la au comportement de l’historique du REPL ; l’issue renvoie à bdb et au point d’entrée python -m pdb -c. Confirmez la portée prévue de la persistance, puis vérifiez que les commandes saisies lors d’une session de débogage sont disponibles lors d’une session ultérieure sans perturber la navigation avec les touches fléchées ni les commandes -c existantes.
