我似乎无法让我的@postfork 函数运行......
1 import uwsgi
2 from uwsgidecorators import *
3 from gevent import monkey; monkey.patch_all()

12 DB_DB = 'masked'

14 mysql_conn = None

16 @postfork

19 raise

21 @postfork
22 def setup_pool():
23 global mysql_conn
24 mysql_conn = umysql.Connection()
25 print "HIII"
26 sys.stderr.write(str(mysql_conn.is_connected()))
27 mysql_conn.connect (DB_HOST, DB_PORT, DB_USER, DB_PASSWD, DB_DB)
28 sys.stderr.write(str(mysql_conn.is_connected()))

当我启动 uwsgi 时，我什么也得不到，直到我到达路由（在调用这个 py 应用程序的 nginx 中定义）。下面是我如何启动 uwsgi：
# uwsgi --socket=/tmp/uwsgi_server.sock --master --processes=2 --listen=4096 --disable-logging --loop gevent --async 128 --uid=www-data --gid=www-data --vhost
*** Starting uWSGI 1.1.2 (64bit) on [Thu Apr 19 23:55:32 2012] ***

当我到达路线时，我得到：
HALLO
如何让我的 @postfork 函数运行？我的最终目标是在应用程序功能中获得连接池。
谢谢！
更新：如果我将 --vhost 换成 --wsgi-file=server.py，它会按预期工作。
