[PATCH v3 0/2] submodule: move gitdir into superproject

From: Fredrik Gustafsson <hidden>
Date: 2016-06-15 22:51:48

Move git-dir for submodules into $GIT_DIR/modules/[name_of_submodule] of
the superproject. This is a step towards being able to delete submodule
directories without loosing the information from their .git directory
as that is now stored outside the submodules work tree.

This is done relying on the already existent .git-file functionality.
Tests that rely on .git being a directory have been fixed.

This is the third iteration of this patchseries. In this iteration the
commit message of the second patch is updated and the fixup-patch from
Junio squashed with the first commit.

The first can be found here:
http://thread.gmane.org/gmane.comp.version-control.git/177582

The second can be found here:

[PATCH v3 2/2] Move git-dir for submodules

From: Fredrik Gustafsson <hidden>
Date: 2016-06-15 22:51:48

Move git-dir for submodules into $GIT_DIR/modules/[name_of_submodule] of
the superproject. This is a step towards being able to delete submodule
directories without loosing the information from their .git directory
as that is now stored outside the submodules work tree.

This is done relying on the already existent .git-file functionality.
When adding or updating a submodule whose git directory is found under
$GIT_DIR/modules/[name_of_submodule], don't clone it again but simply
point the .git-file to it and remove the now stale index file from it.
The index will be recreated by the following checkout.

This patch will not affect already cloned submodules at all.

Tests that rely on .git being a directory have been fixed.

[PATCH v3 1/2] rev-parse: add option --is-well-formed-git-dir [path]

From: Fredrik Gustafsson <hidden>
Date: 2016-06-15 22:51:48

Check if [path] is a valid git-dir or a valid git-file that points
to a valid git-dir.

We want tests to be independent from the fact that a git-dir may
be a git-file. Thus we changed tests to use this feature.

While we are talking about names how about:

	--resolve-git-dir

? Since we had this information already the option prints out the found
resolved git directory and could be used for that.

My question is perhaps a bit beyond the scope of this series...

Is there going to be a way to migrate submodules to the new layout?  If the
eventual goal is to be able to delete & restore submodule working
directories, it would be nice if that could work with submodules cloned by an
older git.

That's not planned as far as I know. However, a new clone will do that,
(and of course it's quite easy to do it manually).

When git supports to delete and restore submodules that will not be done
if there isn't a .git-FILE in the submodule.
