[PATCH 0/5] Advice on checkout dirty files

From: Arsh Srivastava via GitGitGadget <gitgitgadget@gmail.com>
Date: Mar 10, 2026, 08:51 UTC
Message-ID: <pull.2233.git.git.1773132678.gitgitgadget@gmail.com>

This is my submission for microproject [GSOC]

This patch adds a new advice type ADVICE_STASH_BEFORE_CHECKOUT to help users when they attempt to switch branches with local modifications that would be overwritten by the operation.

The new advice follows the same patterns established by existing advice functions such as advise_on_updating_sparse_paths(). When triggered, it lists the affected files and suggests using git stash push/pop to save and restore local changes.

The advice can be silenced with:

git config set advice.stashBeforeCheckout false

Changes:

> advice.h: add ADVICE_STASH_BEFORE_CHECKOUT enum value advice.c: add
> "stashBeforeCheckout" to advice_setting[] and implement
> advise_on_checkout_dirty_files() function
> Documentation/config/advice.adoc: document the new advice key
