From ccee60862bbba6aa65fafbdb1ce357d2b31a795b Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 25 Jun 2011 22:41:25 +0200 Subject: [PATCH] submodule sync: do not auto-vivify uninteresting submodule Earlier 33f072f (submodule sync: Update "submodule..url" for empty directories, 2010-10-08) attempted to fix a bug where "git submodule sync" command does not update the URL if the current superproject does not have a checkout of the submodule. However, it did so by unconditionally registering submodule.$name.url to every submodule in the project, even the ones that the user has never showed interest in at all by running 'git submodule init' command. This caused subsequent 'git submodule update' to start cloning/updating submodules that are not interesting to the user at all. Update the code so that the URL is updated from the .gitmodules file only for submodules that already have submodule.$name.url entries, i.e. the ones the user has showed interested in having a checkout.
