From 04c1ee576accad4d0a04f168b86992aba0a6727d Mon Sep 17 00:00:00 2001 From: Jens Lehmann Date: Sun, 13 Oct 2013 13:52:05 +0200 Subject: [PATCH] mv: Fix spurious warning when moving a file in presence of submodules In commit 0656781fa "git mv" learned to update the submodule path in the .gitmodules file when moving a submodule in the work tree. But since that commit update_path_in_gitmodules() gets called no matter if we moved a submodule or a regular file, which is wrong and leads to a bogus warning when moving a regular file in a repo containing a .gitmodules file: warning: Could not find section in .gitmodules where path= Fix that by only calling update_path_in_gitmodules() when moving a submodule. To achieve that, we introduce the special SUBMODULE_WITH_GITDIR define to distinguish the cases where we also have to connect work tree and git directory from those where we only need to update the .gitmodules setting. A test for submodules using a .git directory together with a .gitmodules file has been added to t7001. Even though newer git versions will always use a gitfile when cloning submodules, repositories cloned with older git versions will still use this layout.
