This project aims to replace the builtin git-http-backend CGI handler distributed with C Git with a Rack application. This reason for doing this is to allow far more webservers to be able to handle Git smart http requests.
The default git-http-backend only runs as a CGI script, and specifically is only targeted for Apache 2.x usage (it requires PATH_INFO to be set and specifically formatted). So, instead of trying to get it to work with other CGI capable webservers (Lighttpd, etc), we can get it running on nearly every major and minor webserver out there by making it Rack capable. Rack applications can run with the following handlers:
These web servers include Rack handlers in their distributions:
With Warbler, and JRuby, we can also generate a WAR file that can be deployed in any Java web application server (Tomcat, Glassfish, Websphere, JBoss, etc).
Since the git-http-backend is really just a simple wrapper for the upload-pack and receive-pack processes with the '--stateless-rpc' option, it does not actually re-implement very much.
$ gem install rack $ (edit config.ru to set git project path) $ rackup --host 127.0.0.1 -p 8080 config.ru $ git clone http://127.0.0.1:8080/schacon/grit.git
If you would like to contribute to the Grack project, I prefer to get pull-requests via GitHub. You should include tests for whatever functionality you add. Just fork this project, push your changes to your fork and click the 'pull request' button. To run the tests, you first need to install the 'mocha' mocking library and initialize the submodule.
$ sudo gem install mocha $ git submodule init $ git submodule update
Then you should be able to run the tests with a 'rake' command. You can also run coverage tests with 'rake rcov' if you have rcov installed.
