copied!<p>What you are asking is a typically a <strong><a href="https://stackoverflow.com/questions/216212#216228">merge workflow</a></strong> problem: what to merge from where to where. </p> <p>But you also need to remember that in a DVCS, a merge will also be influence by <strong><a href="https://stackoverflow.com/questions/1039817/git-commit-frequency/1040502#1040502">publication considerations</a></strong> (are those branches pushed to local repositories, or public ones)</p> <p>"master" branch in particular is the one visible by default when someone clone your repo, meaning it should reference what you consider most useful to that user/developer. (since <a href="https://stackoverflow.com/questions/904353/unable-to-understand-git-branch-merge-and-rebase/905284#905284">other branches are not referenced locally by default</a>)</p> <hr> <blockquote> <p>1/ When I add some feature on release-2 and it should go to 3 as well, but not to 1</p> </blockquote> <p>You can indeed merge r2 to master, after having made a number of commits to r2 in order to achieve the necessary evolutions. That way, only a limited number of commits are visible in master, avoiding "commit cluttering".<br> For r3 however, you can cherry pick what you need from r2, if r3 is being pushed and published. Otherwise, you could rebase r3 on r2. See "<a href="https://stackoverflow.com/questions/457927/git-workflow-and-rebase-vs-merge-questions/457988#457988">git workflow and rebase vs merge</a>" question</p> <blockquote> <p>2/ When I need to changes sth in all the versions, should I do it on master and cherry-pick it to all the branches?</p> </blockquote> <p>You should do it on r2, and then merge on master and r1 and r3. That way, only one commit is added to those branches.</p> <blockquote> <p>3/ Should I keep master up to date with the newest(release-3 branch) or rather developer on release-3 and merge to the master just before I will need release-4 branch?</p> </blockquote> <p>It depends on what you want your other colleague to see when they clone the repo.<br> But from 1/, I gather master is representing r2 (current development) and not r3 (future, long-term refactoring)</p> <blockquote> <p>4/ When I fix sth on release-1 or release-2, should I merge or cherry-pick it to master or rather?</p> </blockquote> <ul> <li>r1: cherry-pick: not all what you are fixing on r1 is meant to be merged to current development.<br> Actually, I would rather cheery-pick r1 fixed on r2, make sure everything work there, and then merge on master.</li> <li>r2: merge. If master represents r2, a simple merge is enough.</li> </ul>
