是否有一种方法可以在生产中重新加载代码而不重新启动Zope?新功能几乎每两天实现一次,并且必须上传到服务器。它目前工作的唯一方法是重新启动zeo服务器和所有实例。不能使用"plone.reload“,因为它只在调试模式打开时才能在开发环境中工作。下面是buildout.cfg内容

如果您部署得如此频繁,您可以在低流量时间(即夜间)部署。
如果网站应该总是在运行,您可以有两组Plone实例:一组是活动的和服务请求的,另一组是不活动的。
当更新时,离线服务器被更新,当它们完成时,一个开关(例如HAProxy)被打开以替换活动服务器。
您甚至可以让所有服务器始终可用,但要进行更新,则在更新时将一些服务器脱机。
正如其他人以及您所指出的,我永远不会在生产中使用plone.reload或类似的开发工具。

是的,有一种方法,尽管我不会在生产中这样做,但是在开发过程中,在浏览器视图中重新加载是一个很好的节省时间的方法:
from plone.reload.code import reload_code
from Products.Five.browser import BrowserView
class View(BrowserView):
def __call__(self):
reload_code()
return 'Code loaded.'然后用您在站点上注册的名称调用视图。当实例在后台运行时,这甚至在非调试模式下工作。使用独立实例(非ZEO)进行测试。
