What is a Pull Request?
From Github's Using Pull Requests Page
Pull requests allow you tell others virtually changes you lot've pushed to a GitHub repository. Once a pull asking is sent, interested parties can review the gear up of changes, hash out potential modifications, and even push follow-up commits if necessary.
Pull Requests are commonly used by teams and organizations collaborating using the Shared Repository Model, where anybody shares a single repository and topic branches are used to develop features and isolate changes. Many open source projects on Github use pull requests to manage changes from contributors as they are useful in providing a style to notify project maintainers nigh changes one has made and in initiating lawmaking review and general discussion about a set of changes before existence merged into the main branch.
Here's an example pull asking from jQuery's github repo.
Creating a Pull Request
There are 2 primary work flows when dealing with pull requests:
- Pull Request from a forked repository
- Pull Request from a branch within a repository
Here we are going to focus on 2.
Creating a Topical Co-operative
Outset, we volition demand to create a co-operative from the latest commit on master. Make sure your repository is upwardly to engagement commencement using
Annotation: git pull does a git fetch followed by a git merge to update the local repo with the remote repo. For a more detailed caption, run into this stackoverflow postal service.
To create a co-operative, use git checkout -b <new-branch-name> [<base-branch-proper name>], where base-co-operative-proper name is optional and defaults to master. I'm going to create a new branch called pull-asking-demo from the master co-operative and push information technology to github.
git checkout -b pull-request-demo git push button origin pull-request-demo Creating a Pull Request
To create a pull request, y'all must have changes committed to the your new branch.
Go to the repository folio on github. And click on "Pull Asking" button in the repo header.
Pick the co-operative you wish to have merged using the "Caput co-operative" dropdown. You should get out the rest of the fields as is, unless yous are working from a remote branch. In that case, just make certain that the base repo and base of operations branch are set correctly.
Enter a championship and clarification for your pull request. Remember you can apply Github Flavored Markdown in the clarification and comments
Finally, click on the green "Ship pull request" push to finish creating the pull request.
Y'all should now see an open pull asking.
Using a Pull Request
You can write comments related to a pull request,
view all the commits by all independent past a pull request nether the commits tab,
or run across all the file changes from the pull request across all the commits under the "Files Changed" tab.
Yous can event leave a comment on particular lines in the code change simply by hovering to the left of a line and clicking on the bluish notation icon.
Merging a Pull Asking
One time you and your collaborators are happy with the changes, you lot beginning to merge the changes back to master. At that place are a few ways to do this.
Outset, you can utilize github'southward "Merge pull request" push at the bottom of your pull request to merge your changes. This is only bachelor when github can detect that there will be no merge conflicts with the base of operations branch. If all goes well, you merely take to add a commit bulletin and click on "Confirm Merge" to merge the changes.
Merging Locally
If the pull request cannot be merged online due to merge conflicts, or you wish to exam things locally earlier sending the merge to the repo on Github, y'all can perform the merge locally instead.
You tin detect the instruction to practise and so by clicking the (i) icon on the merge bar.
However, there's an alternative that may be better for long continuing branches.
Squash, Rebase, and Ruby Choice
In long continuing branches, merging can oft cause lots bug when updating if changes in a given co-operative conflict with changes recently merged into the primary branch. If there are many commits to the same file, git merge may force you to ready the same merge conflicts over and over once again, causing a real headache. While there are many ways to mitigate this effect, such every bit enabling git rerere to reuse recorded resolution of conflict merges, squashing a series of related changes into 1 commit and cherry-picking it into the master is a great solution, especially for topic branches and isolated features.
There are several advantages of performing merges this way. Outset, you lot but have to deal with merge conflicts once, since all commits are compressed into one. Second, each commit represents an entire set of changes required for a feature or task, which makes it easy to pin point bugs and other issues when they arise and to remove a change set when information technology'southward no longer necessary.
There are besides disadvantages of squashing commits. First, you will lose the details and information for each change, as all changes squashed are compressed together. So the cyberspace consequence is the same. Second, information technology tin can be unsafe and problematic if used incorrectly, such as squashing commits that have been pushed to the remote server and others depend on for their work. Because squashing is changing the git history, you tin crusade many conflicts that way. However, if you lot are using this locally or you are the only person working on your branch and y'all know exactly what y'all are doing.
To perform this, use the following command
-i stands for interactive mode and HEAD~x ways to examine the 10 latest commits.
If you run across an fatal: Needed a single revision error, this usually ways that there are non that many commits left. Endeavour a lower number.
This will open up up an editor with git commit messages that looks something similar this:
There are many options bachelor at this stage. These are detailed in this github help folio. Here, I'g going to simply squash all changes in this pull request into one. Salvage and shut the editor.
The adjacent screen will pop up asking you lot to edit your commit messages. You tin choose to edit them or simply continue. Salvage and shut the editor.
Once your squash completes, you lot can button it to the remote repo. In this case, these squashed commits take been pushed to the server. However, I'm the but user of this branch and can safely strength button the commit to update the git repo.
git push origin pull-request-demo -f To merge the commit, we will utilize git cherry-pick.
You are done! Github should detect the changes and update the pull asking. You can then marked the pull request as merged and optionally delete the branch.
Closing a Pull Request
Y'all can simply click on the "Close" push on the pull asking to close it. Optionally, yous can delete the branch directly using the "Delete this branch" button.
