It’ll overwrite the remote repository with your local references (and your local branches). Warningĭon’t use git push -mirror in repositories that weren’t cloned by -mirror as well. $ git push -mirror will get all the branches and tags that are available in the upstream repository and will replicate those into the new location. If you haven’t cloned the repository before, you can mirror it to a new home by $ git clone -mirror cd upstream-repository.git Mirroring a git repository without a local copy The difference lays on whether you already have a working copy of that repository or not. You’ll need to do this when migrating your upstream repository to a new “home”, like when switching services like GitHub.Īs with most tools, there’s a lot of ways to accomplish that, but I’ll be focusing on two of them. By state, we mean all the branches (including master) and all the tags as well. However, what we want with mirroring is to replicate the state of an origin repository (or upstream repository). ![]() When people talk about mirroring a git repository, usually we have a simple answer in mind: We could also specify refs/heads/ if we wanted the branch.Īt this point, any git command can specific enough check out any branch or tag without “ambiguity”, it’s best to rename the branch by creating a new one and deleting the previous branch or remove and create a new tag so that the two do not have this collision.How to properly mirror a git repository May 21, 2013 The folder structure is the same that is would needed to append. State without impacting any branches by performing another checkout. You can look around, make experimentalĬhanges and commit them, and you can discard any commits you make in this Note: checking out 'refs/tags/release/v1.0.0'. If we meant to ‘checkout’ the Tag, being more specific is required. Warning: refname 'release/v1.0.0' is ambiguous.īy default, git has chosen the Branch. What will happen if we tell git to ‘checkout’? 1 Assume we have mistakenly created a Tag release/v1.0.0 and a Branch release/v1.0.0. If a collision has occurred Git will relay that with a message like the following. However, feature branches and release branches bring in much more opportunities. If the team is only using master and develop collisions with these two branches will be very rare. You can find the common parent in git using merge-base to do a Tag on code from the past. Versus when we releasing code from the master branch. It makes sense in a case like this to use naming conventions on the tags to keep from colliding on the branch names. You should never name a tag and a branch the same name! If the team wishes to be able to maintain the release for any period of time, a Tag should be created at the point in which the code has diverged. Moving code into a master branch creates a release-able set of code. Take care naming tags and branches to keep from confusing GitĪssume there is a master branch of code and a develop branch of code. ![]() ![]() When Tags and Branches are both used, they give flexibility to teams to share commit history and easily communicate important changes in code, but naming them similarly will lead to collisions if not well thought out. While this can be true, this is not what a Branch represents and may lead to Tags being used interchangeably with Branches. Confusion can be had when assuming a branch is always the HEAD, or most recent, commit in the fork of the code. A basic understanding in Git is that Tags are aliases to a commit hash (A single entry in the history of commits) whereas a Branch is the name for a diverged chain of commits that share a common history and ancestor. ![]()
