Planning ahead for threads and more interactivity in rev apps

[xavier.bury at clearstream.com]

Thanks for everyone's input...

I came to the conclusion that my once-simple scanning program ended up 
with too many reporting features. So i have to separate them. I will have 
3 different applications in the end. One for scanning, one for monitoring 
the scanning and one to do the reporting.

I cannot use sockets or the like just because of the complexity it would 
add to the system plus the lack of tracking should anything go wrong. This 
is the same kind of issues with a cgi-based processes - if any of them 
hang, you dont know which one it is and you must kill all the processes to 
be clean again... We've had lots of issues with this which is why i wont 
go that way.

The plan i made is to write simple transactions to files and have a cmd 
helper run these. These create their logs which is what i need and then 
delete the transaction file once done. This way if anything happens i can 
track where it went wrong (the transaction is not deleted for example)... 
Also i can limit the number of processes easily since rev creates the 
transactions
only if there is no excess transactions left to be done...

Thanks too all who answered for your help and suggestions!
