问题
I\'d like to check out a previously created pull request (created via GitHub web interface). I searched and found different places where a refs/pull or refs/pull/pr
But when I add fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to the git config file and do a git fetch
What I\'m doing wrong? Should GitHub create automatically the pull/xyz stuff, or do I have to configure something?
回答1:
To fetch a remote PR into your local repo,
git fetch origin pull/ID/head:BRANCHNAME
where ID is the pull request id and BRANCHNAME is the name of the new branch that you want to create. Once you have created the branch, then simply
git checkout BRANCHNAME
See the official GitHub documentation for more.

This will fetch without you having to name a branch:
git pull origin pull/939/head
How do I get a specific pull request on my machine?

That gist does describe what happend when you do a git fetch:
Obviously, change the github url to match your project's URL. It ends up looking like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
Now fetch all the pull requests:
$ git fetch origin
From github.com:joyent/node
* [new ref] refs/pull/1000/head -> origin/pr/1000
* [new ref] refs/pull/1002/head -> origin/pr/1002
* [new ref] refs/pull/1004/head -> origin/pr/1004
* [new ref] refs/pull/1009/head -> origin/pr/1009
...
To check out a particular pull request:
$ git checkout pr/999
Branch pr/999 set up to track remote branch pr/999 from origin.
Switched to a new branch 'pr/999'
You have various scripts listed in issues 259 to automate that task.
The git-extras project proposes the command git-pr (implemented in PR 262)
git-pr(1) -- Checks out a pull request locally
SYNOPSIS
git-pr <number> [<remote>]
git-pr clean
DESCRIPTION
Creates a local branch based on a GitHub pull request number, and switch to that branch afterwards.
The name of the remote to fetch from. Defaults to
origin.EXAMPLES
This checks out the pull request
226fromorigin:
$ git pr 226
remote: Counting objects: 12, done.
remote: Compressing objects: 100% (9/9), done.
remote: Total 12 (delta 3), reused 9 (delta 3)
Unpacking objects: 100% (12/12), done.
From https://github.com/visionmedia/git-extras
* [new ref] refs/pull/226/head -> pr/226
Switched to branch 'pr/226'

I prefer to fetch and checkout without creating a local branch and to be in HEAD detached state. It allows me quickly to check the pull request without polluting my local machine with unnecessary local branches.
git fetch upstream pull/ID/head && git checkout FETCH_HEAD
where ID is a pull request ID and upstream where is original pull request has been created (it could be origin, for example).
I hope it helps.

Referencing Steven Penny's answer, it's best to create a test branch and test the PR. So here's what you would do.
- Create a test branch to merge the PR into locally. Assuming you're on the master branch:
git checkout -b test
- Get the PR changes into the test branch
git pull origin pull/939/head:test
Now, you can safely test the changes on this local test branch (in this case, named test) and once you're satisfied, can merge it as usual from GitHub.

If you are using Github.com, go to "Pull requests", click on the relevant pull request, and then click on the "command line instructions" link:

The problem with some of options above, is that if someone pushes more commits to the PR after opening the PR, they won't give you the most updated version. For me what worked best is - go to the PR, and press 'Commits', scroll to the bottom to see the most recent commit hash and then simply use git checkout, i.e.
git checkout <commit number>
in the above example
git checkout 0ba1a50

You can use git config command to write a new rule to .git/config to fetch pull requests from the repository:
$ git config --local --add remote.origin.fetch '+refs/pull/*/head:refs/remotes/origin/pr/*'
And then just:
$ git fetch origin
Fetching origin
remote: Counting objects: 4, done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 4 (delta 2), reused 4 (delta 2), pack-reused 0
Unpacking objects: 100% (4/4), done.
From https://github.com/container-images/memcached
* [new ref] refs/pull/2/head -> origin/pr/2
* [new ref] refs/pull/3/head -> origin/pr/3

For Bitbucket, you need replace the word pull to pull-requests.
First, you can confirm the pull request URL style by git ls-remote origin command.
$ git ls-remote origin |grep pull
f3f40f2ca9509368c959b0b13729dc0ae2fbf2ae refs/pull-requests/1503/from
da4666bd91eabcc6f2c214e0bbd99d543d94767e refs/pull-requests/1503/merge
...
As you can see, it is refs/pull-requests/1503/from instead of refs/pull/1503/from
Then you can use the commands of any of the answers.

I'm using hub, a tool from github: https://github.com/github/hub
With hub checking out a pull request locally is kinda easy:
hub checkout https://github.com/owner/repo/pull/1234
or
hub pr checkout 1234

I accidentally ended up writing almost the same as provided by git-extras. So if you prefer a single custom command instead of installing a bunch of other extra commands, just place this git-pr file somewhere in your $PATH and then you can just write:
git pr 42
// or
git pr upstream 42
// or
git pr https://github.com/peerigon/phridge/pull/1

If you're following the "github fork" workflow, where you create a fork and add the remote upstream repo:
14:47 $ git remote -v
origin git@github.com:<yourname>/<repo_name>.git (fetch)
origin git@github.com:<yourname>/<repo_name>.git (push)
upstream git@github.com:<repo_owrer>/<repo_name>.git (fetch)
upstream git@github.com:<repo_owner>/<repo_name>.git (push)
to pull into your current branch your command would look like:
git pull upstream pull/<pull_request_number>/head
to pull into a new branch the code would look like:
git fetch upstream pull/<pull_request_number>/head:newbranch
回答13:
If their commits are on there master branch of their forked repo, then you could just do the following.
git fetch git@github.com:<repo_owner>/<repo_name>.git
git checkout FETCH_HEAD
