Re: [PROPOSAL] Create branch for repository mirroring?

From: Donald Sharp <sharpd_at_cisco.com>
Date: 2002-12-13 16:29:15 CET

What happens when a user attempts a commit, against a copy
of the workspace that isn't up-to-date? For example
suppose the copy repo has version 114. Since then
the main repo has gone to 116. The files that the user
happens to be checking in as part of the change set
are what were changed on 115 and 116?

thanks!
