#define _PAGE_ Accessing source code via CVS

#include "head.t"
|
|
|
|
<h2>Browsing the repositry</h2>
|
|
|
|
<p>Just go <a href="http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/rockbox/">here</a>.
|
|
|
|
<h2>Downloading (checking out) the source</h2>
|
|
|
|
<p>You, obviously, need to have <a href="http://www.cvshome.org">CVS</a> installed to do this.
|
|
|
|
<p>The examples below use the 'firmware' module, since that's what most people are interested in. Here is a complete list of the available modules:
|
|
|
|
<ul>
|
|
<li>firmware - the source code to the actual firmware
|
|
<li>gdb - the gdb stub to use for remote debugging
|
|
<li>tools - tools for building the firmware
|
|
<li>uisimulator - a user interface simulator for X11
|
|
<li>www - the web page
|
|
</ul>
|
|
|
|
<h3>Anonymous read-only checkout</h3>
|
|
|
|
<p>If you are not a registered developer, use this method.
|
|
When asked for a password, just press enter:
|
|
|
|
<p><tt>cvs -d:pserver:anonymous@cvs.rockbox.sourceforge.net:/cvsroot/rockbox login
|
|
<br>cvs -z3 -d:pserver:anonymous@cvs.rockbox.sourceforge.net:/cvsroot/rockbox co firmware</tt>
|
|
|
|
<p>A "firmware" directory will be created in your current directory, and all the source files go there.
|
|
|
|
<h3>Checkout for developers</h3>
|
|
|
|
<p>For this, you need to:
|
|
|
|
<ol>
|
|
<li> Have <a href="http://www.openssh.com">SSH</a> installed
|
|
<li> Have a <a href="http://sourceforge.net/account/register.php">SourceForge account</a>
|
|
<li> Be a
|
|
<a href="http://sourceforge.net/project/memberlist.php?group_id=44306">registered developer</a>
|
|
of the Rockbox project
|
|
<li> Have logged on to your account once (ssh <b>username</b>@rockbox.sourceforge.net) and then waited a few hours for SourceForge to set up your cvs
|
|
</ol>
|
|
|
|
<p>Then run:
|
|
|
|
<p><tt>export CVS_RSH=ssh
|
|
<br>cvs -z3 -d:ext:<b>username</b>@cvs.rockbox.sourceforge.net:/cvsroot/rockbox co firmware</tt>
|
|
|
|
<h2>Checking in modifications</h2>
|
|
|
|
<p>CVS is a "no-reserve" version control system. This means that you work on your local files without first reserving them. Any conflicts with other developers are detected when you check-in, or "commit" as it's called in CVS:
|
|
|
|
<p><tt>cvs commit <b>filename</b></tt>
|
|
|
|
<p>This will start an editor and ask you to describe the changes you've made. If you want, you can use the -m command line option to specify the comment right there:
|
|
|
|
<p><tt>cvs commit -m "This is my change comment" <b>filename</b></tt>
|
|
|
|
|
|
<h2>Updating your repository</h2>
|
|
|
|
<p>Since several people commit to the repository, you will need to periodically
|
|
synchronize your local files with the changes made by others.
|
|
This operation is called "update":
|
|
|
|
<p><tt>cvs update</tt>
|
|
|
|
|
|
<h2>Adding a new file</h2>
|
|
|
|
<p>Adding a file is very simple:
|
|
|
|
<p><tt>cvs add <b>filename</b></tt>
|
|
|
|
<p>If you are adding a binary file, you need to specify the -kb flag:
|
|
|
|
<p><tt>cvs add -kb <b>filename</b></tt>
|
|
|
|
<p>These changes, like any other change, has to be committed before they will be visible on the server.
|
|
|
|
<h2>Querying the status of your files</h2>
|
|
|
|
<p>Sometimes it is interesting to get a list of the status of your files versus
|
|
those on the remote repository. This is called "status":
|
|
|
|
<p><tt>cvs status</tt>
|
|
|
|
<p>The output from "status" can be rather verbose. You may want to filter it with grep:
|
|
|
|
<p><tt>cvs status | grep Status</tt>
|
|
|
|
<p>To only list files who differ from the server, filter again:
|
|
|
|
<p><tt>cvs status | grep Status | grep -v Up-to-date</tt>
|
|
|
|
<h2>Getting rid of the password prompts</h2>
|
|
|
|
<p>Each cvs operation has to be authenticated with ssh. This is normally done
|
|
by you entering your password. This gets boring fast.
|
|
Instead, you can register your public ssh key with your SourceForge account. This way, your connection is authenticated automatically.
|
|
|
|
<p><a href="http://sourceforge.net/account/login.php">Log in</a>
|
|
to your SourceForge account and go to your
|
|
<a href="https://sourceforge.net/account/">account options</a>.
|
|
On the bottom of the page, there is a link to
|
|
<a href="https://sourceforge.net/account/editsshkeys.php">edit your ssh keys</a>.
|
|
Copy the contents of your local <tt>.ssh/identity.pub</tt> or
|
|
<tt>.ssh/id_rsa.pub</tt> there.
|
|
|
|
<p>Like many things on SourceForge, the key change doesn't take effect immediately. You'll have to wait a few hours until some magic batch job kicks in and puts your keys where they should be. Then you can use cvs without entering your password.
|
|
|
|
<p>If you work from several different computers/accounts, you must add the key for each account you are using.
