Subject: git diff: --submodule=diff does not synergise with --name-only
Date: Mon, 03 Nov 2025 10:51:10 +0000	[thread overview]
Message-ID: <C6Lp4oh3zEx1R6wysONzY_opvR6SE1GVNIHwMp1tXuAp_ob7jehtLPbu7XguZdU6vQ_Djq7ADBHOLrn3g4am4brUiiS6yzwpDCjIK_QaR00=@calamity.inc> (raw)

Hi, I'm using Git v2.51.2.windows.1 but this bug may have existed as far back as when --submodule=diff was introduced according to my research.

To reproduce this, you need a repository with a submodule which was changed since a given tag, then it can be observed like so:

1. git diff --name-only --submodule=diff <tag> | wc -l
2. git diff --submodule=diff <tag> | grep "diff --git" | wc -l

You should notice a discrepency between the line counts because in the first case only the submodule path is listed, whereas in the second case it correctly recurses into the submodule and lists the files changed in those submodules.
