cherrypy

问题 I've been searching for a while now but can't find an answere. I know that cherrypy creates a new thread for handling requests (GET, PUT, POST, DELETE etc). Now i fetch the parameters like this: ... @cherrypy.tools.json_in() @cherrypy.tools.json_out() def POST(self): Forum.lock_post.acquire() conn = self.io.psqlConnect(self.dict_psql) cur = conn.cursor(cursor_factory = psycopg2.extras.RealDictCursor) params = cherrypy.request.json ... return some_dict As you can see im locking the thread to

问题 So I'm trying to do more web development in python, and I've picked cherrypy, hosted by lighttpd w/ fastcgi. But my question is a very basic one: why do I need to restart lighttpd (or apache) every time I change my application code, or the code for an underlying library? I realize this question extends from a basic mis(i.e. poor)understanding of the fastcgi model, so I'm open to any schooling here, but I'm used to just changing a PHP file and it showing up, versus having to bounce the web

问题 This question is related to others I have asked on here, mainly regarding sorting huge sets of data in memory. Basically this is what I want / have: Twisted XMLRPC server running. This server keeps several (32) instances of Foo class in memory. Each Foo class contains a list bar (which will contain several million records). There is a service that retrieves data from a database, and passes it to the XMLRPC server. The data is basically a dictionary, with keys corresponding to each Foo

问题 I'm trying to learn to use $http.get requests in AngularJS for a web app that I am writing. I have a locally hosted server that has some API that I have written.
