So git revert is not an option, but you really want to purge the commit as if it never existed? That is not possible without rewriting history (which is considered bad behavior for public repositories) You can use a cherry-picking workflow where you cherry-pick the good commits, once you are sure they are good indeed. > > The plan is to use the Git History Rewriting capability described here > https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History > So I can pull a pull workspace from the public ³testing-stage² repository > use the above mechanism to eject one or more commits from it. > > Now I would like to be able push it back to public ³testing-stage² > repository. when using the cherry-pick workflow above (cherry picking from testing to public), you can still merge back public to testing > And allow other people to be able to sync their workspaces to this public > ³testing-stage² repository, correctly. git fetch testing && git reset --hard testing-stage test-branch would do that client side. > > This as I understand is not supported?/recommended? in GIT. It is supported as Git is a toolkit and you can align your workflow using different tools from the box.

Rewriting history is considered bad practice, and that is probably the reason why there are no good tools AFAIK to verify rewritten history easily. When you consider published history permanent, you can use gpg or local tags to know what "is already good" and only inspect new incoming deltas for correctness. > What needs to be done in terms of development, to support this > functionality and make it work properly in GIT? > Is there additional development that needs to be done to git core to allow > this development process? I think the workflow you described can be done using current tools. You would just need to polish things or create aliases for things as this seems to be an unusual workflow?
