Re: VCS comparison table

Dear diary, on Wed, Oct 18, 2006 at 10:53:16AM CEST, I got a letter
where Andreas Ericsson [off-list ref] said that...

Anyone can push and pull from each other - full stop. Whenever they
'pull' in bzr terms, they get fast-forward happening (if I understand
the git fast-forward behaviour correctly). After a fast-forward, the
dotted decimal revision numbers in the two branches are identical - and
they remain immutable until another fast forward occurs.

You can determine it locally - if you know any of the motherships
revisions locally, we can generate the dotted-revnos that the
motherships master-branch would have from the local data - and the last
merge of mothership you did will have given you that details.

To me, this means bazaar isn't distributed at all and I could achieve 
much the same distributedness(?) by rsyncing an SVN repo, working 
against that and then rsyncing it back with some fancy merging. In other 
words, bazaar requires there to be one Lord of the Code, or some of the 
key features break down.

Well as far as I understand, the Lord of the Code is whoever you pulled
from the last time.

It's just a different focus here. If I understood everything in this
thread correctly, both Git and Bazaar have persistent (SHA1, UUID) and
volatile (revspec, revision number) revision ids. The only difference is
that Git primarily presents the user with the SHA1 ids while Bazaar
primarily presents the user with a revision number (and that revspecs
change after every commit while revision numbers change only after a
merge).
