Apache/Windows/mod_wsgi上有多个django站点 - win32问题

Question

我有两个django站点使用相同的数据库并共享一些代码.主要的父网站是员工和承包商的外联网,而第二个网站则向我们的一些合作伙伴公开了一些数据.

我已设法设置网站工作,但发现如果我启动Apache并进入主站点,那么合作伙伴网站将无法工作,返回"内部服务器错误".如果我重新启动并进入合作伙伴站点,那么主站点将无法运行.

所以我猜他们在资源方面存在冲突.

服务器日志(见下)显示它是win32/lib/pywintypes.py模块第114行的问题.在其他地方,建议注释掉这些行(见下文).所以我试过这个并且它有效.

我真的不明白代码中发生了什么,以及评论它是否会在以后引起我的问​​题.所以问题是:

还有其他事情可能导致这种情况吗？这个软糖"安全"吗？

# py2k and py3k differences:
# On py2k, after doing "imp.load_module('pywintypes')", sys.modules
# is unchanged - ie, sys.modules['pywintypes'] still refers to *this*
# .py module - but the module's __dict__ has *already* need updated
# with the new module's contents.
# However, on py3k, sys.modules *is* changed - sys.modules['pywintypes']
# will be changed to the new module object.
# SO: * on py2k don't need to update any globals.
#     * on py3k we update our module dict with the new module's dict and
#       copy its globals to ours.
old_mod = sys.modules[modname]
# Python can load the module
mod = imp.load_dynamic(modname, found)
# Check the sys.modules[] behaviour we describe above is true...
if sys.version_info < (3,0):
    #The fudge bit !!!!!!!!!!!!!!!!!
    #assert sys.modules[modname] is old_mod 
    #assert mod is old_mod
    pass
else:
    assert sys.modules[modname] is not old_mod
    assert sys.modules[modname] is mod
    # as above - re-reset to the *old* module object then update globs.
    sys.modules[modname] = old_mod
    globs.update(mod.__dict__)
