Today, I have completed the basic isolation of session and errors between various running web applications. This complete the basic infrastructure for multiple app execution with each having it’s own environment space.

Now, bracing again for modules development!

I am now adding multiprogramming capability to the SPP. Initially, I had planned to defer it’s implementation till next version. But now, I feel that this would require a lot of code rewrite. So, I have now decided to implement it in this version itself. In this regard, today I started coding a class SPP_App. Along with this, some changes in the SPP_Registry and SPP_Module were also made to suit it for the multiprogramming environment.

I know that many people will jump over me on the use of word “Multiprogramming”, as it is grenerally used in the terms of Operating Systems. But that is the direction in which SPP is now heading. It will support simultaneous execution of multiple Web Applications providing them exclusive memory spaces.

Happy testing till next post.

According to the “Minimal at core and extendable by modules” philosophy, the HTML and validators have been moved out of the core. They are now available of SPP_Optional modules.

A new method ‘addEventHandler’ was added to the SPP_Event class today. Now, it is possible to define multiple handlers for a single event in addition to existing setting a new handler functionality. The occurence types available with this handler are – ‘before’ and ‘after’. This means this event handler cannot override the default handler. This is logical, as it does not make any sense to override an event handler with multiple handlers.
