From 967b2c66738fe6b168ead0c3106ac47fb9ae22c7 Mon Sep 17 00:00:00 2001 From: Jon Seymour Date: Wed, 6 Jun 2012 21:57:29 +1000 Subject: [PATCH] submodule: fix sync handling of some relative superproject origin URLs When the origin URL of the superproject is itself relative, git submodule sync configures the remote.origin.url configuration property of the submodule with a path that is relative to the work tree of the superproject rather than the work tree of the submodule. To fix this an 'up_path' that navigates from the work tree of the submodule to the work tree of the superproject needs to be prepended to the URL otherwise calculated. Correct handling of superproject origin URLs like foo, ./foo and ./foo/bar is left to a subsequent patch since an additional change is required to handle these cases. The documentation of resolve_relative_url() is expanded to give a more thorough description of the function's objective.
