Re: Push tag from shallow clone?

The documentation for git clone says that if you use --depth=1 to make
a shallow clone that you can't push it. But I made a shallow clone,
created a tag, then tried to push that tag and it worked. Am I just
getting lucky or is it safe to push a tag with a shallow clone?

Yea, you are getting lucky.  The tag is easily identified as one
object head of the current branch on the remote, and the client is
able to produce the pack and send it.

If the remote branch gets modified in the interm, the builder may
not be able to deduce what it needs to send, and will attempt to
pack a lot more data, potentially finding the missing parents from
where it is shallow.

Why not just have a central area on the build server that keeps
full clones of everything, and use "git clone -s" or "git clone
--reference" in order to create the new work area for the builder?
