How to prevent from race conditions to share data between many process and thread in python
I use TurboGears to do some web service. TurboGears use cherrypy. When web browser access this site, the cherrypy will call my python program. So my program looks like a lib. When web browser access the site, the http server will fock a process or gerenate a thread. I need share some data or operate some files. How can I prevent from race conditions. Is there any way can I lock this. Thank you in advance! -- http://mail.python.org/mailman/listinfo/python-list
