From 502c386ff944898c1327a5b5a0fefcd4f62d613a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?SZEDER=20G=C3=A1bor?= Date: Sun, 25 Aug 2019 20:59:18 +0200 Subject: t7300-clean: demonstrate deleting nested repo with an ignored file breakage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 'git clean -fd' must not delete an untracked directory if it belongs to a different Git repository or worktree. Unfortunately, if a '.gitignore' rule in the outer repository happens to match a file in a nested repository or worktree, then something goes awry and 'git clean -fd' does delete the content of the nested repository's worktree except that ignored file, potentially leading to data loss. Add a test to 't7300-clean.sh' to demonstrate this breakage. This issue is a regression introduced in 6b1db43109 (clean: teach clean -d to preserve ignored paths, 2017-05-23).
