Hi, I'd like to argue, that topgit (tg) fails to fullfill it's task and propose a different approach to the problem of patch management on top of git.
IMHO tg fails due to the following reasons: - it's to complicate - AFAIK nobody has solved the problem of managing different patchsets with tg - it pollutes the patch branches with metadata (.topmsg, .topdeps) - even after 1 1/2 years topgit isn't feature complete and development seems to stagnate - there also aren't best practices documented - it quickly fills the list of branches - it's very easy to break something Although the above is quite a harsh judgement, I'd like to note, that tg has had its merrit to promote one right idea: Patches should be managed in the form of branches by the means of the underlying VCS and not as simple patchfiles. The new approach I'd like to propose is based on two core ideas: 1) merge commits to save history git allows the free creation of merge commits with an arbitrary content tree. So we can create an octupus merge combining all patch-branches while the content of this merge can contain meta data about a patchset instead of the content of the merged commits. Such a merge commit thus provides a pointer to all the history of all patches and can contain all metadata about the merged patch branches. Pushing only a branch or tag with this commit to a central repository thus pushes all the history of all contained patches. 2) collapse / expand branches Managing a Debian package in stable, unstable and experimental can quickly doom you to manage at least three different patchsets with possibly three different roots. The list of branches grows in the douzens. Which branches belong to which patchset? Which branches are already pushed or pulled? It may be an advantage to see only some main branches and the branches of one patchset I'm currently working on. The tool I propose would manage each patchset in one branch per patchset. This branch has two roles: - keep the metadata of the patchset as files in the content tree - keep pointers to the top of the patch-branches in the parent pointers of the commit With the help of such a patchset-metadata-branch I can: - delete the patch-branches of one patchset while the commits are kept save - recreate the patch-branches of one patchset For Debian packaging one last function is needed: export a patchset as quilt series. Is my explanation understandable? Could this approach work or did I miss something? Who has time to implement it (GSOC?)?
