From f109e7eeb53ecfa084f80899646b68fb6dff021d Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Fri, 1 Jul 2016 11:01:18 +0200 Subject: [PATCH] support/download/git: add support for submodules Some git repositories may be split into a master repository and submodules. Up until now, we did not have support for submodules, because we were using bare clones, in which it is not possible to update the list of submodules. Now that we are using plain clones with a working copy, we can retrieve the submdoules. Add an option to the git download helper to kick the update of submodules, so that they are only fetched for those packages that require them. Also document the existing -q option at the same time. Submodules have a .git file at their root, which contains the path to the real .git directory of the master repository. Since we remove it, there is no point in keeping those .git files either. Note: this is currently unused, but will be enabled with the follow-up patch that adds the necessary parts in the pkg-generic and pkg-download infrastructures. Signed-off-by: "Yann E.
