Re: git-alltrees: root trees and subtrees without duplicate commits.

[Douglas Leonard <dleonard.dev@gmail.com>]

Just an update, this has been cleaned up with a python implementation,
with a decent bit of added functionality, particularly tag-renaming,
and it's been working well.  It's already pip installable.  Maybe I'll
get around to adding it to pypl.. maybe.

Cheers,
Doug

But maybe more importantly, when it pulls from the trees it's able to "remap" or reconstruct old commits back to their originals to avoid the duplicate commit issue of subtrees.  This is round-trip reproducible so consistency is kept both ways. It avoids the need for squash with subtrees. Compare the two images in the wiki to see the difference between subtree without squash and alltrees. Non-FF changes made in a tree repo show as branched and merged. Traditional advantages of subtrees are kept, primarily that users/developers of any one repo don't need any awareness of how to use the subtrees or the other repos.
