The idea of this extension is to abstract away the submodule gitdir path implementation: everyone is expected to use the config and not worry about how the path is computed internally, either in git or other implementations. With this extension enabled, the submodule.<name>.gitdir repo config becomes the single source of truth for all submodule gitdir paths. The submodule.<name>.gitdir config is added automatically for all new submodules when this extension is enabled. Git will throw an error if the extension is enabled and a config is missing, advising users how to migrate. Migration is manual for now. E.g. to add a missing config entry for an existing "foo" module: git config submodule.foo.gitdir .git/modules/foo Suggested-by: Junio C Hamano <gitster@pobox.com> Suggested-by: Phillip Wood <phillip.wood123@gmail.com> Suggested-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Adrian Ratiu <adrian.ratiu@collabora.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
