Django中的Forking

Question

我试图在django视图中创建os.fork()，但得到一个错误：Port 8000 already in use。据我所知，当我这样做时，os.fork()文件描述符被继承，并且我在两个进程中的同一端口获得了两个套接字。

   def view(request):
       ...
       if not os.fork():
          target()
       return

    def target(*args, **kwargs):
       ...
       sd = socket.socket(*args, **kwargs)
       sd.bind(*args)
       sd.listen()
       nsd = sd.accept()
      ...

如果我在子级中对打开的描述符执行错误，我会得到WSGI- os.close()：

for i in os.listdir("/proc/%s/fd" % os.getpid()):
   os.close(int(i))

Traceback (most recent call last):
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 94, in run
    self.finish_response()
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 135, in finish_response
    self.write(data)
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 218, in write
    self.send_headers()
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 274, in send_headers
    self.send_preamble()
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 197, in send_preamble
    self._write('HTTP/%s %s\r\n' % (self.http_version,self.status))
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 404, in _write
    self.stdout.write(data)
  File "/usr/lib/python2.6/socket.py", line 318, in write
    self.flush()
  File "/usr/lib/python2.6/socket.py", line 297, in flush
    self._sock.sendall(buffer(data, write_offset, buffer_size))
error: [Errno 9] Bad file descriptor

我需要这一点作为单独的进程，我不想使用3-d党的应用程序，如芹菜。

我认为正确的解决方案是使用芹菜(http://docs.celeryproject.org/en/latest/)或类似的东西。
