I don't think it gets much better than Django's approach. Basically, the server code loads everything it needs to bootstrap, and then forks. All the request handling and subsequent code execution takes place in the child process, so that when modules are loaded, they are only loaded into the child's memory space. Then, before any request is processed, the child checks the originating files for all of the modules in sys.modules, and sees if any of them have a new modification date. If so, the child process is killed, which is detected by the parent, which respawns the child. The respawned child has the state of the parent process (which hasn't loaded any external modules), so modules get freshly imported. t.p.rebuild() is a big improvement over the stock reload() function, but in addition to requiring modules to be marked with the "ALLOW_TWISTED_REBUILD" flag, it suffers from the same issue that it's only able to reload modules that are in the current scope. -phil _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
