Hi Sergio, I hate to turn anyone away from mod_python, but I have to agree with everything Nicolas says. If you can switch to a new development environment and code your application in less that 2 weeks... well you are a better man than I, Sergio. Granted we aren't talking about Zope here, but still... Even if you can deliver your app on time, there is still the hosting issue. My personal feeling is that mod_python is not suitable for a shared hosting environment at this time. It's too hard, or even impossible, to isolate each virtual host. Consider session locking as an example. Session locking makes use of global mutexes which are a limited resource. One bad application (coding error or otherwise) could consume all the locks on the server, effectively starving every other virtual host which is using sessions so that they are all hosed. I'd certainly like to see mod_python reach the point where it's suitable for use in a shared hosting environment, and is as ubiquitous as php. There are changes that can be made to make it better, but there may be some fundamental issues which cannot be resolved. I think mod_python fits in a niche where the developer has a much greater degree of control over the apache server. The ideal situation is where you have your own apache server process, such as your own server or a virtual host setup. Somebody like openhosting.com comes to mind. (I'm not affiliated - just putting a plug in for our BDFL ;) ) Good luck with your project, be it in mod_python or otherwise. Regards, Jim PS. my development environment: gvim, subversion, ssh, rsync - who could ask for anything more?
