I have patches in quilt (for ktest only, not for my other work) and will start adding them on a "clean" release. By doing a git pull (or fetch and merge), I like to see the fast forward to know if everything that's in my current branch has been pulled. If it hasn't, then something may have been missed. > > or > > git checkout -b mywork v3.4-rc5 ;# to start But then I would end up with several branches that would require deleting. One way I could see myself in handling this case would be to delete the current branch and start again (thinking that everything was already pulled). But by doing that, if something wasn't pulled in, then I would have lost those changes without ever knowing. > > So the case to "reset to" is not very interesting. > > But when a normal developer wants to _sync to_ a particular tagged > release, in order to _continue_ working on her topic, she would need to > have a merge (unless she does not have _anything_ herself), and at that > point, merging v3.4-rc5 vs v3.4-rc5^0 would not make that much of a > difference.

If they specify the fast-forward flag, then the user would expect the merge to be a fast forward if possible. BTW, is there a git compare type option. That is, I like to compare two separate branches with the result that one currently gets with git when a branch is following another branch. When you check out that branch, it gives you an update on how those two branches are related (is one a fast forward of the other, are they off by different commits?). It would be nice if git could do this with any two branches. I wrote a script to do this for me (attached) but it would be nice if git had it natively. $ git-branch-status v3.0.4 v3.0.5 Branch v3.0.4 can be fast forward to v3.0.5 in 240 commits $ git-branch-status v3.0.4 v3.1 Branch v3.0.4 and v3.1 differ by 257 and 9380 commit(s) respectively -- Steve
