Re: collapsing old git history to reduce repo size, while preserving commit #s and tags

Hi,

I have an old git repo with e.g. 1000 commits, that grew up to
considerable size.
Now, I am starting a new project and want to use this repo, but "slimmed down".

I'd like to clone the repo to the new project and "slim it down"
I'd like to collapse 900 first commits into one, but keep last 100,
with their commit numbers and tags. I also want to be able to push and
merge changes from the old repo to the new one.

I've read about git rebase, but it seems to tamper with commit numbers
and looses tags.. Is there any other way to have it done ?

thanks!!

If you want to change the actual history of your repository, it will
be largely incompatible with the original, and this is by design. You
don't want somebody being able to change your history without you
knowing about it.

It sounds like a shallow checkout might be appropriate for you, try
looking that up.
