Sharing and Updating Projects

|

Git doesn't have a central server like Subversion. All of the commands
|
||||
so far have been done locally, just updating a local database.
|
||||
To collaborate with other developers in Git, you have to put all that
|
||||
data on a server that the other developers have access to. The way Git
|
||||
does this is to syncronize your data with another repository. There
|
||||
is no real difference between a server and a client - a Git repository
|
||||
is a Git repository and you can syncronize between any two easily.
|
||||
</p>
|
||||
|
||||
<p>Once you have a Git repository, either one that you set up on your
|
||||
own server, or one hosted someplace like GitHub, you can tell Git to
|
||||
either push any data that you have that is not in the remote repository
|
||||
up, or you can ask Git to fetch differences down from the other repo.
|
||||
</p>
|
||||
|
||||
<p>You can do this any time you are online, it does not have to correspond
|
||||
with a <code>commit</code> or anything else. Generally you will do a
|
||||
number of commits locally, then fetch data from the online shared repository
|
||||
you cloned the project from to get up to date, merge any new work into the
|
||||
stuff you did, then push your changes back up.</p>
|
||||
|
||||

|
||||
<b>In a nutshell</b> you can update your project with <code>git fetch</code>
|
||||
and share your changes with <code>git push</code>.

|

|
||||
<p>Unline centralized version control systems that have a client that is
|
||||
very different from a server, Git repositories are all basically equal and
|
||||
you simply syncronize between them. This makes it easy to have more than
|
||||
one remote repository - you can have some that you have read-only access to
|
||||
and others that you can write to as well.</p>
|
||||
|
||||
<p>So that you don't have to use the full URL of a remote repository every
|
||||
time you want to syncronize with it, Git stores an alias or nickname for
|
||||
each remote repository URL you are interested in. You use the
|
||||
<code>git remote</code> command to manage this list of remote repos that
|
||||
you care about.</p>
|
||||
|
||||
<h4>
|
||||
git remote
|
||||
<small>list your remote aliases</small>
|
||||
</h4>
|
||||
|
||||
<p>Without any arguments, Git will simply show you the remote repository
|
||||
aliases that it has stored. By default, if you cloned the project (as
|
||||
opposed to creating a new one locally), Git will automatically add the
|
||||
URL of the repository that you cloned from under the name 'origin'. If
|
||||
you run the command with the <code>-v</code> option, you can see the
|
||||
actual URL for each alias.</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git remote</b>
|
||||
origin
|
||||
<b>$ git remote -v</b>
|
||||
origin git@github.com:schacon/git-reference.git (fetch)
|
||||
origin git@github.com:schacon/git-reference.git (push)
|
||||
</pre>
|
||||
|
||||
<p>You see the URL there twice because Git allows you to have different
|
||||
push and fetch URLs for each remote in case you want to use different
|
||||
protocols for reads and writes.</p>
|
||||
|
||||
<h4>
|
||||
git remote add
|
||||
<small>add a new remote repository of your project</small>
|
||||
</h4>
|
||||
|
||||
<p>If you want to share a locally created repository, or you want to take
|
||||
contributions from someone elses repository - if you want to interact in
|
||||
any way with a new repository, it's generally easiest to add it as a remote.
|
||||
You do that by running <code>git remote add [alias] [url]</code>. That
|
||||
adds <code>[url]</code> under a local remote named <code>[alias]</code>.</p>
|
||||
|
||||
<p>For example, if we want to share our Hello World program with the world,
|
||||
we can create a new repository on a server (I'll use GitHub as an example),
|
||||
which should give you a URL, in this case "git@github.com:schacon/hw.git".
|
||||
To add that to our project so we can push to it and fetch updates from it
|
||||
we would do this:</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git remote</b>
|
||||
<b>$ git remote add github git@github.com:schacon/hw.git</b>
|
||||
<b>$ git remote -v</b>
|
||||
github git@github.com:schacon/hw.git (fetch)
|
||||
github git@github.com:schacon/hw.git (push)
|
||||
</pre>
|
||||
|
||||
<p>Like the branch naming, remote alias names are arbitrary - just as 'master'
|
||||
has no special meaning but is widely used because <code>git init</code>
|
||||
sets it up by default, 'origin' is often used as a remote name because
|
||||
<code>git clone</code> sets it up by default as the cloned-from URL. In
|
||||
this case I've decided to name my remote 'github', but I could have really
|
||||
named it just about anything.
|
||||
</p>
|
||||
|
||||
<h4>
|
||||
git remote rm
|
||||
<small>removing an existing remote alias</small>
|
||||
</h4>
|
||||
|
||||
<p>Git addeth and Git taketh away. If you need to remove a remote - you are
|
||||
not using it anymore, the project is gone, etc - you can remove it with
|
||||
<code>git remote rm [alias]</code>.</p>
|
||||
|
||||
<pre>
|
||||
<b>$ git remote -v</b>
|
||||
github git@github.com:schacon/hw.git (fetch)
|
||||
github git@github.com:schacon/hw.git (push)
