[MTOS-dev] New Dispatcher On the Way

[Reed A. Cartwright]

I made some changes the mt-dispatch last weekend.  The current code can 
be found here:

http://scit.us/cgi-bin/csvn/misc/mt-dispatch/current/mt-dispatch.fcgi

I've added support for autodetecting settings changes and restarting the 
worker threads.  I'm thinking that it may even work with the upgrade 
process, although I haven't tested it.

I've also changed the way the publishing queue is handled.  The script 
now uses Sys::AlarmCall (available from CPAN) to balance waiting for a 
request and processing a job from the publishing queue.

Minor changes have been made to the rc.d script as well.

I'll make an official release when I'm satisfied that it is running 
smoothly on my two servers, but feel free to look at my code, linked 
above and tell me what you think.

And finally, I'm willing to merge this dispatcher with MTOS for 4.2 
release.  I can suggest some minor changes to make it work better like 
removing need to read a file to know what app class to call, and instead 
rely on the Applications registry key.

Down the road, I think that much of the code in the current 
implementation should be scrapped for FCGI::Engine and 
CGI::Application::Dispatch, like I wrote in my prototype many weeks ago.
