You want the raw git-commit-tree tool. Suppose your branches are tmp
and hourly (both in refs/heads). Something like this should make your
hourly commit:
commit=$(
echo hourly-commit |
git commit-tree refs/heads/tmp^{tree} -p refs/heads/hourly)
git update-ref -m "hourly commit" refs/heads/hourly $commit
It might be that you should then start basing your temporary commits on
the most recent archive, so you should also
git update-ref -m "hourly commit" refs/heads/tmp $commit
Then what you'll end up with is something like
a-----------a-----------a-----------a
\ $\ $\ $
\-t---t---t \-t---t---t \-t---t---t
Does that seem sane?
