Subject: [RFC PATCH v2 10/12] t7416: add new test about HEAD:.gitmodules and not existing .gitmodules
Date: Thu,  2 Aug 2018 15:46:32 +0200	[thread overview]
Message-ID: <20180802134634.10300-11-ao2@ao2.it> (raw)
In-Reply-To: <20180802134634.10300-1-ao2@ao2.it>

git submodule commands can now access .gitmodules from the current
branch even when it's not in the working tree, add some tests for that
scenario.

For the test files I used the most used style in other tests, Stefan suggested
to avoid subshells and use "git -C" but subshells make the test look cleaner
IMHO.

+test_description=' Test reading/writing .gitmodules is not in the working tree
+
+This test verifies that, when .gitmodules is in the current branch but is not
+in the working tree reading from it still works but writing to it does not.
+
+The test setup uses a sparse checkout, but the same scenario can be set up
+also by committing .gitmodules and then just removing it from the filesystem.
+
+NOTE: "git mv" and "git rm" are still supposed to work even without
+a .gitmodules file, as stated in the t3600-rm.sh and t7001-mv.sh tests.
