We use Eclipse to edit our content. In order to test our content, we have two choices: (1) push your work to git.eclipse.org which will (in a matter of minutes) copy the files to the live web server where you can test; or (2) setup a local unit test environment. The benefit of (1) is that it takes very little effort. Unfortunately, by committing to the Git server and copying to the web server, your work is made public; in effect, you are testing your work on the live web server where everybody can see it. As long as everything goes well, this is fine. The second option is to set up a local unit test environment where you can actually test your work before you make it available to the adoring masses. Intuitively, the second option is safer, and tends to work a lot better when you're disconnected (for whatever reason).

Note that you can also use Orion to Edit your project website.

Setting up Eclipse

Installing PHP Development Tools (PDT)

You can use the text editor to edit your PHP files, but the PHP Development Tools make the experience much better. Use the "Install new software..." option in Eclipse 3.5+ to add the PHP Development Tools to your configuration.

Workspace

Create a new project name 'www' in your workspace (if you have installed the PDT, then make this a PHP project).

Create a clone of your Website directory

The first thing that you need to know if the URL of the Git repository that you'd like to work with. In Git parlance, we need to make a clone of that repository on the Orion server. You will make edits in the local copy on Orion and then "push" your changes (commits) back to the Eclipse Git server.

Your project's website directory will be located under www.eclipse.org on the Git server. The website for your project will be in a directory named <project-short-name>.git (e.g. orion.git). Click on your project repository, scroll down to the bottom and copy the "ssh://..." URL listed under "Clone" (e.g. ssh://git.eclipse.org/gitroot/www.eclipse.org/orion.git).

Use eGit to clone the repository into a ~/git/www (or an equivalent directory).

If you intend to test locally, also clone the 'eclipse.org-common' directory into the ~/git/www directory (note that you can do this later if you change your mind).

You should now be able to edit the files on your website, and push (commit) them to test them live.

Creating a Server

Read on if you'd like to set up a local test server (that will allow you to test locally before you commit to the live server).

FWIW, if you are new project, chances are that breaking your project's website for a few minutes is not a big deal. That is, you may be able to defer setting up a test server.

Most Linux distributions provide the means to install Apache 2.0+ and PHP 5.0+. If you know what you're doing, you can also install these pieces on other platforms, such as Windows. However, distributions such as XAMPP make this much easier.

Installing XAMPP

XAMPP is a distribution of Apache HTTP Server that also includes PHP 5.0.x, MySQL and other useful software. As of October 2006, version 1.5.4 seems to contain the right versions of the parts we need.

The first step is to actually obtain XAMPP from the download web site. Depending on how paranoid you are, you can download a one-step installer for some platforms, or you can download the ZIP file and unpack it yourself. The one-step installer variant does fun things like install the web server as a service on Windows (and probably messes around with your registry). Decide for yourself how paranoid you are about that sort of thing.

In these instructions, we're going to set up Apache so that it runs files directly out of your workspace. This makes testing really easy since you don't have to copy anything anywhere to make it work. However, the following configuration instructions are a little twisted for good reason: if you're not careful, open some security holes on your workstation. These instructions will help you configure Apache so that only you can access the contents of your workspace from your workstation.

Ensure short PHP tags are enabled

in your php.ini file, ensure short tags are enable. This can be set in a global /etc/php.ini or a site specific one

short_open_tag = On

To configure Apache, you're going to have to edit the "http.conf" file. This file is located in the "apache" directory in the XAMPP installation.

Setup a Virtual Host

In this section, you'll set up a virtual host for Apache. This virtual host will be known only to your workstation (and so will only work when used from your workstation).

Open the "httpd.conf" file. Scroll to the bottom and add the following section:

<Directory "/home/''[userid]''/git/www">
	AllowOverride All
	Order allow,deny
	Allow from all
</Directory>

<VirtualHost local.eclipse.org:80>
    DocumentRoot /home/''[userid]''/git/www
    ServerName local.eclipse.org:80
    ErrorLog logs/phoenix
    CustomLog logs/phoenix common
</VirtualHost>

Replace "/home/[userid]/git/www" with the path to your 'www' directory (we've suggested ~/git/www which translates to something like "/home/[userid]/git/www"). If you have opted to use a different name, use it instead of "www".

Open your hosts file using your favourite text editor. On Windows, this file is likely located at c:\windows\system32\drivers\etc\hosts. Add the following line to this file:

127.0.0.1	local.eclipse.org

This adds the name local.eclipse.org to the list of names your computer knows about. Unless this name is propogated to some shared DNS and mapped to your machine's IP address, nobody else will be able to use this address to access your computer. This line tells Windows that when a browser makes a request to http://local.phoenix.eclipse.org, that the local machine will handle it. Your configuration of Apache has ensured that all requests coming into that address on the default port (80) will be handled by Apache using documents found in your workspace.

File/Directory Permissions

You may have to modify directory permissions (depending on operating system and configuration) to make this work. On Linux systems, the entire directory chain leading to your 'www' directory need to be marked executable by the web user. On Windows, this should just work (score one for Windows "security").

Installing Apache 2.0 and PHP 5.0 on Ubuntu Linux

Note that you will need root access to make all of these changes.

Use the package manager to install Apache 2.0 and PHP 5.0.

Create the file /etc/apache2/sites-available/local.eclipse.org with the following content:

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName local.eclipse.org
    DocumentRoot [workspace location]/www
    ErrorLog	/var/log/apache2/local.eclipse.org.log

<Directory [workspace location]/www>
    AllowOverride All
    Order Allow,Deny
    Allow from ALL
</Directory>
</VirtualHost>

Replace [workspace_location] (2 occurrences!) with the path to your Eclipse workspace. This assumes that you will store the web content in a directory named "www" (this is what the directory is called on the CVS server). If you have opted to use a different name, use it instead of "www".

Add the following line to your /etc/hosts file:

127.0.1.1	local.eclipse.org

Execute the following:

a2ensite local.eclipse.org
/etc/init.d/apache2 restart

And you should be in business.

Note that you may have to grant read access of your workspace files to the webserver.
