I am using git bundle to back up git repositories. In recent versions of git the repository metadata of a submodule are stored in .git/modules of the parent repository as opposed to before when it was stored in a .git directory right in the submodule.
When git-bundle is run in a submodule, it creates a bundle of the parent repo, omitting the submodules.
Anyone who can shed light on this?
How can I make a git bundle of a submodule?
reference: question on the git mailing list
edit:
After reading that for sschuberth it works, I wrote a script to test and can verify that it works. I have a backup script that relied on verifying the existence of a .git directory in order to know if it is in the top level dir of a repository and that thus broke when submodules started using .git files. If anyone knows what the recommended way is to garantee that you are in the top level folder of a repository, I'm interested. I don't know how I missed this.
Just in case it might interest someone who has to write test scripts for submodules, this is the script I used:
#!/bin/bash
git --version
mkdir super
mkdir subRemote
touch super/superFile.txt
touch subRemote/subFile.txt
cd super
git init
git add --all
git commit -am"Initial commit"
cd ..
cd subRemote
git init
git add --all
git commit -am"Initial commit"
cd ..
cd super
git submodule add ../subRemote/.git
git add --all
git commit -am"added submodule"
git submodule update
echo -e "\ngit log in super:"
git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --date=relative --all
cd subRemote
echo -e "\ngit bundle:"
git bundle create ../../submoduleBundle --all --remotes
cd ..
cd ..
git clone --mirror submoduleBundle bundledSub/.git
cd bundledSub
git config core.bare false
git config core.logallrefupdates true
git remote rm origin
git checkout
cd ..
#------------------------------------------------
cd super
echo -e "\nfiles in super":
ls -alh
cd ..
cd super/subRemote
echo -e "\nfiles in super/subRemote":
ls -alh
cd ../..
cd bundledSub
echo -e "\nfiles in bundledSub":
ls -alh
cd ..
Are you sure that running git submodule update succeeded and the .git file (not directory) in the submodule exists? In my tests bundling submodules works fine with version 1.7.9.6.
If it still fails for you for some reason, a work-around would be to clone the submodule's repository into its own working tree and run git bundle from there (for the commit as shown by git submodule status in the superproject).
