I never thought about the shared hosting part, thanks for boosting my morale, I would be quite happy if you would comment on my relevant page

This was my first lua script, so some parts might have been wrong. Still, I think the first injection was needed, and your third message seems to confirm this so it gives me some confidence

Regarding your second message, it’s possible. There was a new release of mysql-proxy just after I published this, and apparently, some changes rendered my script obsolete. I’ve joined the mysql-proxy team on launchpad to try to keep a closer eye on the project and I promise to make an updated post on this blog with a new script that works.

In fact, if it’s approved by the team, I’ll publish in the cookbook where it’ll be much more useful.

I think your project is quite interesting and might be in fact easier to implement for people working on the LAMP stack and on shared hosting environments (where installing the proxy is totally out of the question), so please keep up the good work!

Also to achieve this, you dont need the read_query and the global query, since in.query will give the original query as read here: http://dev.mysql.com/doc/mysql-ha-scalability/en/mysql-proxy-scripting-read-query-result.html

Open PHP MyProfiler is just a trial to run query profiling on a php-mysql application, without changing the architecture too much. The profiler is open and downloadable, though the analzer, is just a mockup or a bare one and not yet ripe to be opened up. Any one who needs to do the analysis could make use of the same by downloading the profiler, and implementing with their code. The profiler would create logs depending on hostname and date. upload the profile logs to our Profile Sampler and you should be able to see the full profile of your application.
