Here's my attempt to formulate how I understand the problem at this point current assumptions/limitations: - the application can be shutdown without handling a request / which makes it orthogonal to the requests handling - the underlying code may use threads, making it unreliable to use atexit() - using signals may be problematic if some other code use it too -- for example the wsgi server itself -> the cleanest way seems to ask the web server itself to ping the wsgi app. problems: - how can we declare a shutdown entry point in the application, the web server can use. - how can this work with extra indirections (FASTCGI, etc) leads: - define startup/shutdown functions, declare them to the web server - use the existing environ to send a 'shutdown request' - Cheers Tarek -- Tarek Ziadé | http://ziade.org
