This article provides a step-by-step guide for obtaining a local copy of the Epsilon website.
- Download and install XAMPP.
- The folder where web-content is placed is htdocs.
- Create an epsilon folder inside htdocs.
- Clone the Git repository at ssh://firstname.lastname@example.org/gitroot/www.eclipse.org/epsilon.git using EGit, specifying your Eclipse committer username in youruser. Eclipse will ask for your committer password. The destination directory should be the epsilon directory created in the previous step.
- Import the working directory of the Git repository as a single general project.
- Start XAMPP and go to http://localhost/epsilon.
- You are now ready to start playing with the Epsilon site locally.
- Once you've happy with the changes you've made, go back to the epsilon project in Eclipse, refresh and then commit and push the changes to Git. The site should be updated within a few minutes.
Using lighttpd instead of XAMPP
You can also use lighttpd
with PHP instead of XAMPP, following this tutorial
and pointing server.document-root
to your htdocs
directory, checked out as above. Alternatively, in most Debian-based GNU/Linux distributions, installing the lighttpd
packages and adapting this minimal configuration should be enough:
server.document-root = "/path/to/htdocs"
server.port = 8080
index-file.names += ( "index.html", "index.htm", "index.php" )
mimetype.assign = ( ".html" => "text/html", ".htm" => "text/html",
".css" => "text/css", ".txt" => "text/plain",
".jpg" => "image/jpeg", ".png" => "image/png" )
server.modules += ( "mod_cgi" )
cgi.assign = ( ".php" => "/path/to/php-cgi" )
You can then launch the lighttpd server and leave it running on the foreground with:
lighttpd -D -f lighttpd-epsilon.conf
If you use lighttpd in Windows, use Windows-style paths (c:\...
) instead of Cygwin-style (/cygdrive/c/...
) paths. Otherwise, PHP will not work correctly.
- The HTML output includes bits of PHP code: make sure that short_open_tag is set to On in your php.ini file. It seems to be set to Off by default in the latest distributions of XAMPP and PHP.
- All you get is No input file specified: make sure that doc_root is set to the path to the htdocs folder in your php.ini file.
Finding broken links
can be used to find broken links in the Epsilon website. First, we will traverse the website using wget
with this command:
wget -e robots=off --spider -r --no-parent -o wget_errors.txt http://localhost:8080/epsilon/
We have used these options:
- -e robots=off makes wget ignore robots.txt. This is OK in this case, as we're running the spider on our own local server.
- --spider prevents wget from downloading page requisites that do not contain links
- -r makes wget traverse through links
- --no-parent prevents wget from leaving /gmt/epsilon/
- -o wget_errors.txt collects all messages in the wget_errors.txt file
Once it's done, we can simply search for the word "404" in the log, with:
grep -B2 -w 404 wget_errors.txt
We will get a list of all the URLs which reported 404 (Not Found) HTTP error codes.
To find broken links in the Epsilon blog
, it is better to use -l 3
(3 levels of recursion for the spider) rather than --no-parent
, as we might want to check if external links are broken as well. We use three levels so we can go to the month in the "Archives", then to the full article, and finally to the external link itself.
