managing properties/configurations
Hi, Am sure many would have stumbled on this situation while developing an application in Python which is highly driven by configuration/ properties. I have an application (obviously written in Python) wherein the properties change frequently and the program needs to work according to the new rules. Since , python is scripting language the idea of a Properties file(analogous to Java) doesnt make sense to me. However, at the same time i am looking for some mechanism by which the hot- patches(i.e, properties can be changed) can be applied easily. Since the patches(mostly properties change) will be mostly be done by non-programmers, i do not want them to touch the Py codes,but at the same time alter the behaviour suitably.(Kindly avoid the advice to teach Python to the non-programmers :D ). The following is a *very simple example* of the case wherein the properties(namely 10,30,31,40) are 'hardcoded' - i want this to be 'away' from the code. def checkCutoff(self,up,down): .do some processing if (10 <= score <= 30): result="Bad" elif (31 <= score <= 40): result="Good" .do some processing return result If i have to have this as a separate script that stores all the properties, then how do I make the program fetch the new values without restarting. Also, i would be interested in providing a GUI for manging the properties so that the changes can be applied even more easily - but at any time i do not want to bring down the program and then restart(all are hot patches).

Re: managing properties/configurations
Or a better example would be: I have the params in a config file and import this module: myconfig.py a=10 b=30 c=31 d=40 import myconfig def checkCutoff(self,up,down): .do some processing if (a <= score <= b): result="Bad" elif (c <= score <= d): result="Good" .do some processing return result Now when i 'manually' make some changes to the value of a,b,c,d then the the checkCutoff func should refer to the new values. -Venkat -- http://mail.python.org/mailman/listinfo/python-list

The problem being, if i change the config file, then the configobj has to reload this file again. I do not want to 'refresh' the config obj per transaction but only when the config params change. > > Now when i 'manually' make some changes to the value of a,b,c,d then > > the the checkCutoff func should refer to the new values. > > Maybe reload the file each time you run the program? The program is never-ending and do not think in terms of websites here - probably something like a server/middleware which can never be brought down. I was thinking along the terms of an Interrupt driven program, which when getting a custom interrupts reloads the file - any potential loopholes/falls that anyone can anticipate?
