Yes, that's a good point. I think in Git part of the reason less people track pu is because its very volatile. Not because of the rewind policy, but becuase sometimes the code there doesn't work properly so using it for real "production" work is pretty risky. On the other hand most of the code that merges into next has been reasonbly well reviewed and tested, so following it for "production" work is not as risky. Junio has in the past proposed rewinding next, especially after a significant release (e.g. 1.5.3). A bunch of folks (myself included if I recall correctly) didn't want to do this, as we create topic branches locally from things in next and sometimes make commits over them to improve the topic further. But I also make topic branches for things in pu, so I might as well just shut up and not complain. :-) Of course another thought that just came to mind is it is very easy for me to review next with a git log -p --reverse origin/next..build-next just before merging it into my build branch and compiling it locally. If next rewound frequently (as pu does) this would be more difficult. -- Shawn. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
