Here someone has created a branch called feature1 from the main branch, and you've then created a branch called feature2 from feature1. GitHub automatically updates any such pull requests, changing their base branch to the merged pull request's base branch. If you delete a head branch after its pull request has been merged, GitHub checks for any open pull requests in the same repository that specify the deleted branch as their base branch. For more information, see " Deleting and restoring branches in a pull request"
You can't delete branches that are directly associated with open pull requests. You must have write access in the repository to delete branches. For more information, see " About pull requests."Īfter a pull request has been merged, or closed, you can delete the head branch as this is no longer needed. Once you're satisfied with your work, you can open a pull request to merge the changes in the current branch (the head branch) into another branch (the base branch). For more information, see " Managing the default branch for your repositories," " Managing the default branch name for repositories in your organization," and " Enforcing repository management policies in your enterprise." Working with branches You can set the name of the default branch for new repositories. For more information, see " Changing the default branch." You can change the default branch for an existing repository.
#GIT CREATE BRANCH FROM EXISTING BRANCH CODE#
Unless you specify a different branch, the default branch in a repository is the base branch for new pull requests and code commits.īy default, GitHub names the default branch main in any new repository. The default branch is also the initial branch that Git checks out locally when someone clones the repository. The default branch is the branch that GitHub displays when anyone visits your repository. This first branch in the repository is the default branch. When you create a repository with content on, GitHub creates the repository with a single branch.
For more information, see " Access permissions on GitHub." About the default branch You must have write access to a repository to create a branch, open a pull request, or delete and restore branches in a pull request. For more information, see " About GitHub Pages." You can also use a branch to publish a GitHub Pages site. For more information, see " Creating and deleting branches within your repository." A branch you create to build a feature is commonly referred to as a feature branch or topic branch. You can then work on this new branch in isolation from changes that other people are making to the repository. Typically, you might create a new branch from the default branch of your repository. You always create a branch from an existing branch. If we do git branch -vv again, we can see that jsChanges is now mapped to origin jsChanges.Branches allow you to develop features, fix bugs, or safely experiment with new ideas in a contained area of your repository. We can do -set-upstream or we can do -u, and then origin jsChanges. We have to push while setting the upstream to the origin jsChanges, just like this is origin master. When we do, we get a fatal error, because if we do git branch -vv, we don't have jsChanges linked to any remote branch. If we do a git log oneline, then we have "Adds Hello World" on the jsChanges branch, which has diverged from the master branch. We'll commit that and we'll say, "Adds Hello World."
Then, let's save that and do a git status. We'll make a function called helloWorld again, and we can say alert i. Master is linked to a remote, but jsChanges is just a local branch for now. If we do git branch -vv, for verbose mode, then we can see the current commit that we're on for each branch, and we can see the remote that we're on for each branch. We can also do git branch to see all of our branches. If we do a git status, we can see that we're on the branch jsChanges. That's what we'll do to make a new branch. We can do git branch and then our branch name like jsChanges or we can do git checkout -b jsChanges. Instructor: We can create a new branch in two different ways.
