Bug Description

This is a wishlist bug. Filing on the recommendation of Jeff Bailey.

We have lightweight checkouts, which depend entirely on access to the upstream branch, and heavy checkouts, which are fully independent and have full history. Would it be possible to have a hybrid checkout, which had some of the history locally, but not all of it?

The idea is that the checkout would be "heavy" when dealing with "recent" commits (for some definition of "recent"), but would go into "light" mode when the user started working with commits beyond "recent". Most importantly, the user could work offline and commit just like a "heavy" checkout for the most common case, where the previous few revisions are all that the user cares about.

Darcs has something like this: "darcs get --partial" only retrieves the most recent changesets.

I think this is what's been discussed on the mailinglist as "history
horizons". Where a branch (bound or not bound) only have a part of the
history.

I too, really would like this, but mostly for unbound branches.

Even though there's a spec I think there's no existing bug issue for it,
so let's leave it open as wishlist.

Thanks Jeff

No progress, as far as I can tell. The wiki page is still there (moved to http://wiki.bazaar.canonical.com/HistoryHorizon as part of the general migration off bazaar-vcs.org). Links from there to the Launchpad blueprint still work (https://launchpad.net/bzr/+spec/shallow-checkouts).
