This code is a proof of concept implementing a microblogging system like Twitter, but that is completely decentralised. It is designed to be immune to the ``fail whale'' problem as the failure of any one node will not take down the whole network. Much like email and the internet as a whole. There is no central server, instead independent nodes intercommunicate using a simple XML based protocol. In order to implement this one major compromise had to be made. There is no way to implement a ``follow button''. Instead following is achieved by copying a URL which points to the users XML stream. This URL is analogous to an email address. This application is made available under the terms of the Apache Licence. === Installing === The code depends on the open_ssl and GD libraries, the code also depends on the `url_fopen' feature of PHP. All of these need to be enabled in the php.ini file. To install the code first rename the file example_config.php to config.php then fill in the database options. Next the code, including the .htaccess file(may be hidden on *NIX), needs to be copied onto a server. It will automatically work regardless of where it is placed within the server tree. Finally the schema.sql file needs to be imported into the database using PHPMyAdmin or another MySQL client. === Known limitations === -- This code WILL NOT work without mod_rewrite enabled and the .htaccess file placed on the server. Consequently it will not work with any HTTP server that does not support Apache-style .htaccess files. -- Following users on a different server, when the local server is viewed using the localhost does not work. The remote server gets sent URL's that reference the localhost, rather than the servers IP/domain. To avoid this problem always view the application using the servers public IP address or domain. -- A node running behind a NAT router cannot follow users on a node on the internet and vice/versa. === Test suite === The code has a test suite built using the PHPUnit framework, the test code can be found in the tests/ directory. In order to run the test suite it is necessary to have a web server running on the localhost and a second database. The test suite should NEVER be ran using the primary database as it truncates all of the tables. To run the test suite the file example_config_tests.php needs to be renamed to config_tests.php and filled in with the database settings info. NOTE: The test suite does not auto adapt to the codes location within the server web root, if the code is installed in a subdirectory the option ``APP_ROOT'' needs to be set to reflect this. After this is set up, the tests can be ran by cd'ing into the root of the application and running: phpunit tests/ === Thanks to === JQuery (http://jquery.com/)
