Your guess is mostly correct. To best understand what is going on, keep in mind that "you can never modify, you can only rewrite and forget"[1]. Suppose you say 'git svn dcommit' on history that looks like 1---2---3--(4)--(5) SVN o---o---o (svn/trunk) \ a---b---c (master) where 4 and 5 are commits not yet fetched from SVN (if any). 1. git-svn will first fetch the new SVN history, let's call them N: 1---2---3---4---5 SVN o---o---o---N---N (svn/trunk) \ a---b---c (master) 2. Then it will rebase your own work on top of the new SVN stuff: 1---2---3---4---5 SVN o---o---o---N---N (svn/trunk) \ a---b---c (master) 3. Then it will rebase your own work on top of the new SVN stuff: 1---2---3---4---5 SVN o---o---o---N---N (svn/trunk) \ a'--b'--c' (master) 4. Then it will commit all of that to SVN: 1---2---3---4---5---6---7---8 SVN o---o---o---N---N (svn/trunk) \ a'--b'--c' (master) 5. Then it will annotate your commits o' with the info coming back from SVN (such as author, etc.) and "replace" your master with it: 1---2---3---4---5---6---7---8 SVN o---o---o---N---N---A---B---C (svn/trunk, master) From the point of view of 'master', this is also much like a rebase, except that authors and timestamps change too and (unless disabled) git-svn-id: lines appear in your commit messages. Does that clarify what happens? [For the sake of completeness, I should point out that this is a simplification. Steps 3--5 are actually all done in one go *per commit*, and step 3 does not use 'git-rebase' but a variant on the theme that preserves merges of side branches.] As for > what is the correct usage to keep svn and git in sync? the only way I know of that avoids constantly rebasing branches is to never push anything before it has been dcommitted.
