You don&#39;t actually have a pull request; GitHub just sees that you&#39;ve pushed a branch, and is offering to create a pull request for it if you want.

If you don&#39;t care about that, just ignore it.  It&#39;s completely harmless and will go away as soon as GitHub doesn&#39;t think the branch is &quot;recent&quot;.

I have a mavenized codebased configured Spring 3.2.4 web app. 
When I build the app with Maven/pom.xml first I got an error that web.xml is missing. 
first I tried to create an empty web.xml. this was the moment when The project facets changed (and I don&#39;t know why). It switched from dynamic Web Module 3.0 to 3.1 and this is irreversible. 
How can I change it again into Dynamic Web Modules 3.0???

Additionally I can&#39;t remove the JAX-RS. Trying this it results in:

    Failed while uninstalling JAX-RS (REST Web Services) 1.0.
    org.eclipse.jst.javaee.web.internal.impl.WebAppImpl cannot be cast to org.eclipse.jst.j2ee.webapplication.WebApp

Later I found out that I can avoid the Maven compile error by inserting the according plugin into pom.xml:

    &lt;plugin&gt;
    	&lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
    	&lt;artifactId&gt;maven-war-plugin&lt;/artifactId&gt;
    	&lt;version&gt;2.4&lt;/version&gt;
    	&lt;configuration&gt;
    		&lt;failOnMissingWebXml&gt;false&lt;/failOnMissingWebXml&gt;
    	&lt;/configuration&gt;
    &lt;/plugin&gt;

In python&#39;s library, we now have two Python Implementation of dictionaries which subclasses `dict` over and above the native `dict` type.

Python&#39;s  advocates have always preferred to `defaultdict` over using `dict.setdefault` where possible. Even the [doc](http://docs.python.org/release/2.5.2/lib/defaultdict-examples.html) quotes that `This technique is simpler and faster than an equivalent technique using dict.setdefault():`

In similar ways, as dictionaries does not maintain order, using `OrderedDict` over using `dict` followed by  sorting the items is preferred when ever possible for the alternative usage. 

In both the above case, the code is definitely cleaner but at the cost of performance penalty. 

While answering and commenting on one of the question [python unique list based on item](https://stackoverflow.com/questions/19626749/python-unique-list-based-on-item/19626840?noredirect=1#comment29138676_19626840), I stumbled upon the performance penalty over the native `dict` when using `defaultdict` and `OrderedDict`. It also seems the size of the data is also not immaterial to the performance advantage `dict` solution has over others. 

I believe `There should be one-- and preferably only one --obvious way to do it.`, so what is the preferred way?

I have an existing Visual Studio project in my repository. I recently added a .gitignore file under my project and I assume that tells Git to ignore the files listed in the file. 

My problem is that all those files are already being tracked and as far as I know Git will not ignore a file that was already tracked before a rule was added to this file to ignore it.

It was suggested to use: `git rm --cached` and manually un-track them but that&#39;s going to take me forever to go through them one by one. 

I thought about deleting the repository and recreating it again but this time with .gitignore file present, but there must be a better way to do this.

Is there a quick and easy way to open a git repository in SourceTree from the command line? 

I do a lot of git work from Terminal, but sometimes there&#39;s no replacement for a good history view/diff. Would love to be able to open without using bookmarks.



How do you open SourceTree from the command line?

I happily use vim as my default editor for commits, and do not wish to change it. However, when it comes to rebasing, I find myself squashing dozens and dozens of commits which I find much easier with an interactive editor like Textwrangler (substituting &quot;pick&quot; with &quot;squash&quot; in all but the top commit).

**Is there any way to specify an alternate editor for a one-off rebase command?** 

I know in vim I can do:

    :%s/pick/squash/

but that has its own minor annoyances.

**EDIT** - as stated in the comments, you can squash all but the top commit very efficiently by going to the 2nd line and executing

    :,$s/pick/squash/

(note the comma and dollar are different to the original)

git rebase --editor=/something/other/than/vim? (for easier squashing)

When I push to remote in Git, I get this warning:

    warning: push.default is unset; its implicit value is changing in
    Git 2.0 from &#39;matching&#39; to &#39;simple&#39;. To squelch this message
    and maintain the current behavior after the default changes, use:
    
      git config --global push.default matching
    
    To squelch this message and adopt the new behavior now, use:
    
      git config --global push.default simple
    
    See &#39;git help config&#39; and search for &#39;push.default&#39; for further information.
    (the &#39;simple&#39; mode was introduced in Git 1.7.11. Use the similar mode
    &#39;current&#39; instead of &#39;simple&#39; if you sometimes use older versions of Git)

I remember recently seeing the Travis build status of a pr or commit in GitHub browsing the repository (but can&#39;t find where). I&#39;m not talking about the Travis build status images in `README.md` but an actual GitHub feature (green box with a friendly check mark).

While my commits build on Travis just fine I&#39;d like to get the results displayed in GitHub (which they don&#39;t do right now). I&#39;d like to know how to enable this. 

*UPDATE*

Found an [example here](https://github.com/sebastianbergmann/phpunit/pull/1051/commits) - see the small green check mark saying &quot;Travis-CI build passed&quot;?

I am trying to commit to a project on [github.com][1] from my work laptop, which is already configured for the company git server. Is there a way to commit specifying different author credentials, possible using a different configuration file or orther command line switches?

I&#39;ve tried using

    --author=&quot;My Name &lt;MyNameEmail@email.com&gt;&quot; 

and I received the message: 

     Committer: unknown &lt;WorkEmail@workemail.net&gt;
    Your name and email address were configured automatically based
    on your username and hostname. Please check that they are accurate.
    You can suppress this message by setting them explicitly:
    
        git config --global user.name &quot;Your Name&quot;
        git config --global user.email you@example.com
    
    After doing this, you may fix the identity used for this commit with:
    
        git commit --amend --reset-author

but it still didn&#39;t update my username for committing to the github.com project. Is there anything else I can try and is it even possible?

Seems easy but I just don&#39;t get it. I am in the root of my application.

Here is my workflow.

    git add .
    git commit -m &quot;added a new feature some files changed&quot;
    git push heroku master

This usually works. All my changes are pushed.

But sometimes I have a file that I change but when I push to Heroku the changes are not there for THAT ONE FILE... but for most of the files the changes are there... 

But if I do

    git add .
    git commit -am &quot;added a new feature some files changed&quot;
    git push heroku master

Everything (all changes) are pushed to Heroku

In SVN I have at least two ways to create a branch:

    svn cp /home/me/localcheckout/trunk /home/me/localcheckout/branches/newbranch
    svn cp http://server/trunk http://server/branches/newbranch

The first creates it locally then I have to commit the whole branch.  
The second creates it on the server.

The benefit of the second is that I can svn switch my local trunk, make a few changes to some files and commit just a few KB.

Is it possible to achieve that using Git?  
Is there a way of creating a remote branch on GitHub then pull them to my local repo?

The reason that I ask is that I am trying to push a couple of KB to a new remote branch from master using my phones internet connection but when I push it wants to push about 400 MB!

I&#39;ve just discovered `git checkout --orphan`, but I don&#39;t know how to use it. Its help page says it creates a **new unparented branch**. 

In the `master` branch, I&#39;ve tried `git checkout --orphan br`, only to see the files in the working directory change to &amp;ldquo;Changes to be committed&amp;rdquo;, and the `git log` saying `fatal: bad default revision &#39;HEAD&#39;`.

So what&#39;s the advantage of using  `git checkout --orphan`?

I find myself doing this a lot when cherry-picking a commit from another branch.

    $ git log -1 another_branch
    commit &lt;commit_sha&gt;
    // copy &lt;commit_sha&gt;
    $ git cherry-pick &lt;commit_sha&gt;

Can I do all of this in one command, if so, what is it?

I&#39;m more of a novice when it comes to advanced operations in git. I maintain my [blog](http://jatinganhotra.com) using the blogging framework [Octopress](http://octopress.org/). Though Octopress is not under any development since 2011, it serves my purpose well and so I haven&#39;t thought of changing anything so far.

FYI, my blog is hosted on Github Pages.  

Today, while working on a new post, `git status` showed the following message:

    On branch source
    Your branch is based on &#39;origin/master&#39;, but the upstream is gone.
      (use &quot;git branch --unset-upstream&quot; to fixup)

The same message repeated for all the subsequent commands such as `git add .`, `git commit -m &#39;message&#39;` and `git push origin source`.  

 - What does the message mean?  
 - Is something broken?  
 - If yes, what?  
 - Do I need to fix it? 

If possible, please point me to a pdf/web article where I can read up on this and understand it for future.

More details:

    bash-3.2$ git branch -a
    * source
      remotes/octopress/2.1
      remotes/octopress/HEAD -&gt; octopress/master
      remotes/octopress/gh-pages
      remotes/octopress/linklog
      remotes/octopress/master
      remotes/octopress/refactor_with_tests
      remotes/octopress/rubygemcli
      remotes/octopress/site
      remotes/origin/source

Please let me know if more information is needed. Thanks.

Why call git branch --unset-upstream to fixup?

I&#39;ve pulled all remote branches via `git fetch --all`. I can see the branch I&#39;d like to merge via `git branch -a` as remotes/origin/branchname. Problem is it is not accessible. I can&#39;t merge or checkout.

Git: Merge a Remote branch locally

On Github, you can make pull requests to add functionality to a project. One&#39;s contributions have to be on a branch that, if the request is accepted, will be merged into the master branch (or an analogous one) of the project.

Now, I submitted a pull request on Github and my contributions are on a branch called `patch-1`. I can modify the name of the branch locally by

    git branch -m patch-1 newname

and in principle I can also rename it on my forked repo on Github by following the instruction found in [this answer][1]. This is done in practice by removing the old branch, `patch-1` in my case, and repush it with a different name `newname`.

Is it allowed to rename the branch `patch-1` on my forked repository on Github when it constitutes a pull request?
Or it causes problems on the pull request management?

Is there any way to rename a branch on a forked repository on Github when that branch is a pull request?

Renaming a branch while on pull request

Pull requests seem to be the common way to do code review with Git. However, it is not clear whether this term means the same when using the built-in `git request-pull`, or a different tool.

Are pull requests an intrinsic function of Git, or is it a common term for tools like GitHub, Gerrit or Atlassian Stash?

Is the discussion and &quot;result&quot; of the code review stored in the Git commit history or in a separate database?

Are pull requests part of Git, or a feature of tools like GitHub, Gerrit and Atlassian Stash?

I&#39;m working on a GitHub repo with lots of branches and pull requests.

Let&#39;s say, for example, that I have the following pull requests:

* `a` to branch `X`
* `b` to branch `X`
* `c` to branch `Y`
* `d` to branch `X`
* `e` to branch `Y`.

Is there a way to find all the pull requests that are targeted for branch `X` (i.e. `a -&gt; X`, `b -&gt; X`, `d -&gt; X`)?

How can I filter all GitHub pull requests for a specific target branch

The terminology used to merge a branch with an official repository is a &#39;pull request&#39;. This is confusing, as it appears that I am requesting to push my changes to the official repository.

Why is it called a pull request and not a push request?


Why is a git &#39;pull request&#39; not called a &#39;push request&#39;?

Currently I am working on a really big pull request. In order to keep code-reviews somehow manageable the idea was to split the complete pull request in isolated parts, which however depend on each other.

An example would be:

 - **Pull request 1**: Create interfaces: Interface A &amp; B and restructure code
 - **Pull request 2**: Interface A implementation and Tests (depends on pull request1)
 - **Pull request 3**: Interface B implementation and Tests (depends on pull request2)
 - **Pull request 4**: Mixed test of Implementations (depends on 2 + 3)

Is there a way in Github to file all four pull requests at the same time with dependencies?
