ERP5VCS: Add support for submodules
This MR will help to be able to do basic VCS tasks (commit, diff, merge, etc.) with submodules Business Template in ERP5. This is particularly useful as we are migrating some BT5(s) such as erp5_notebook to act as submodule which are getting large due to data files. We already have support for submodules in slapos gitclone recipe.
This MR can also be used to discuss the naming convention for submodules. As mentioned by @jerome in the comment here , we will be using it for external javascripts also, hence we will be having 2 basic cases. Feel free to add more:
- Business Templates as submodule
- External Libraries as submodule
TODO:
-
Changes in submodule Business Template should reflect properly in the diff (https://lab.nexedi.com/nexedi/erp5/commit/f75b7c3be1504bf682f4ab8427b2bff8ccabe7c3)
New Issues:
-
Checkout from branch with to without submodule and vice-versa is creating issue. (Use post-checkout hook https://ttboj.wordpress.com/2014/05/06/keeping-git-submodules-in-sync-with-your-branches/)
