Recently I came across an issue involving Git submodules which seems like a bug to me. In short (precise reproduction instructions below), if one updates the remote URL of a submodule while it is "deinited", the next time one calls "git update" the old URL will be used instead of the new one. Here is how to reproduce the issue synthetically (in a fresh directory): git init git submodule add https://github.com/git/git-reference sub # random repo git commit -m "add submodule" git submodule deinit sub git submodule init At this point, the remote URL of the submodule has been copied to .git/config. We change it: git config submodule.sub.url "new-url" Now we checkout the submodule. I am expecting to use "new-url" as remote URL in the checkout. git submodule update sub However, the old URL is used: git -C sub config remote.origin.url # => old URL instead of "new-url" The problem seems to be that the clone at .git/modules/sub does not have its remote URL updated when being "inited" after a remote URL change while it was "deinited". Currently I am working around this issue in scripts by doing: if [ -f .git/modules/$sm_name/config ] then git config -f .git/modules/$sm_name/config remote.origin.url $(git config submodule.$sm_name.url) fi Any insight would be appreciated. Thanks! Cheers, Nicolas
