Packaging a git tag
So the other day I was presented with the following requirements.
From a git repository retrieve a history tag and it's commit history to deliver to a client. No other branches should be presented to the client, nor work committed after the tag.
This actually proved to be a little tricky and I'm certain I'm missing some git wizardry but here's what I did.
Clone the repository (foo) to work on locally
git clone myname@github:foo
Checkout the tag and create a branch from it.
cd foo git checkout mytag_1.0.0 git checkout -b mytag_1.0.0_snapshot
Remove all other local branches and cleanup the repository
git branch -D master git gc
At this point you should have a local repository with a single local branch representing the tag you want and a number of references to remote branches. This can be verified with
git branch -a
Now clone your local repository again
cd .. git clone foo foo_final
The foo_final repository should contain nothing but the branch representing the tag at this point.
Zip is up, throw it on a flash drive and deliver as appropriate.
Now I make no claims that this is the best way to do this. In fact I'm certain there should be a better way but this is what I ended up doing.
