assuming security is not of concern at the moment, how can i add in update capability? please help me out or show some pointers to look into.
i wish to change the way the method definition of a class at run time in a running server (actually i m planning to support many changes at run time). new code which is to be executed is provided by a client at different location. i am receiving the code as a string and compile it on server-side with the 'compile' builtin function or get compiled code using marshal. however i cannot link it to the running code in server? for example, i get a new method definition for a method in class and i wish to change it. client sent new definition, i compile it in server, getting a code object. how can i link it to old code? if it will running in same environment, i could simply write A.getdata=getdatanew # A is a class how should i do it here? should i change the way i am receiving the code? thanks for help -piyush On Wed, Jun 25, 2008 at 12:22 AM, Terry Reedy <[EMAIL PROTECTED]> wrote: > > > Piyush Anonymous wrote: > >> any idea or pointer how i could link it to running code in server? >> for example, i get a new method definition for a method and i wish to >> change it. >> client sent new definition, i compile it in server. how can i link it to >> old code? >> > > Code to be hot-updated (while running) must have update capability builtin. > But please consider security.
