Subject: [PATCH] git-submodule - allow a relative path as the subproject url
Date: Sun, 23 Sep 2007 22:19:42 -0400 [thread overview]
Message-ID: <1190600382-1648-1-git-send-email-mdl123@verizon.net> (raw)
In-Reply-To: <11904936042891-git-send-email-mdl123@verizon.net>
This allows a subproject's location to be specified and stored as relative
to the parent project's location (e.g., ./foo, or ../foo). This url is
stored in .gitmodules as given. It is resolved into an absolute url by
appending it to the parent project's url when the information is written
to .git/config (i.e., during submodule add for the originator, and
submodule init for a downstream recipient). This allows cloning of the
project to work "as expected" if the project is hosted on a different
server than when the subprojects were added.

This patch is slightly improved as it removes embedded ./ and ../ sequences
from the url constructed from a base and relative part. It also avoids use
of git-branch in favor of git-symbolic-ref.
