It doesn’t let you switch between branches or put a forked history back together again. The git branch command lets you create, list, rename, and delete branches. New commits are recorded in the history for the current branch, which results in a fork in the history of the project. You can think of them as a way to request a brand new working directory, staging area, and project history. Branches serve as an abstraction for the edit/stage/commit process. How it worksĪ branch represents an independent line of development. The following content will expand on the internal Git branching architecture. Whereas SVN branches are only used to capture the occasional large-scale development effort, Git branches are an integral part of your everyday workflow. The history for a branch is extrapolated through the commit relationships.Īs you read, remember that Git branches aren't like SVN branches. In this sense, a branch represents the tip of a series of commits-it's not a container for commits. Instead of copying files from directory to directory, Git stores a branch as a reference to a commit. The implementation behind Git branches is much more lightweight than other version control system models. By developing them in branches, it’s not only possible to work on both of them in parallel, but it also keeps the main branch free from questionable code. The diagram above visualizes a repository with two isolated lines of development, one for a little feature, and one for a longer-running feature. This makes it harder for unstable code to get merged into the main code base, and it gives you the chance to clean up your future's history before merging it into the main branch. When you want to add a new feature or fix a bug-no matter how big or how small-you spawn a new branch to encapsulate your changes. Git branches are effectively a pointer to a snapshot of your changes. In Git, branches are a part of your everyday development process. Branching in other VCS's can be an expensive operation in both time and disk space. Branching is a feature available in most modern version control systems. If processing is to heavy or this is too big a bandwith burden, this could be added as GIT_SINGLE_BRANCH="yes|no".This document is an in-depth review of the git branch command and a discussion of the overall Git branching model. The proposal is thus by default, enable this flag, so we get expected behavior in that all expected branches are available. Which should resolve this issue, it clones all branches (at depth=). If you want to clone submodules shallowly, also pass -shallow-submodules. single-branch unless -no-single-branch is given to fetch the histories near the tips of allīranches. However, git clone -depth supports an additional argument -no-single-branchĬreate a shallow clone with a history truncated to the specified number of commits. ProposalĪs stated below in #30067 (comment 215829463) not fetching all the branches is expected since we are only going far back X commits. git : << : *common_parameters image : /gitscm/git:latest before_script : - git config -local user.name "$.0-rc1" git push -follow-tags origin "HEAD" done Actual behaviorĪll remotes are available on the runner, albeit at a shallow depth of the main branch Expected behaviorĮven shallow fetch, should always retrieve all branches, not just the current branch. The work around for now appears to be either add a git fetch to the CI task (ugly) or (according to the documentation) set the depth to 0.gitlab-ci.yml This is related to the fact that the branches could not be reached in the current 'depth'. We can create a scenario where not all remotes have been retrieved. However, if git fetch is set with a low depth parameter. To do so, it uses git branch -list -remote "origin/release/v0/*" | sed -n -r 's|.*origin/release/v0/||p' to obtain the list of 'v0' named branches. What the CI will do, checkout the current branch (gitlab-runner does this of course by default), and go over a list of available existing architecture branches to update these. In our project, we want to create architecture specific branches from our main release branch. The default in gitlab is 50, but even this does not guarantee all branches are available. When doing shallow clones (DEPTH=1+), not all remote branches are retrieved, as a matter of fact, only 'reachable' or relevant branches are fetched.
