Probably you have a very different point of view to this changes. Let me explain what I think about that. We have two kind of registries in zope a global/non persistent and local/persistent in local sites. The setSite hooks forces to set the right context for component lookup.

I don't think setup another site is the right concept to use another component registry. Probably there should be an explicit call for the IComponents utility in this case. btw, if you like to register actions for another registry then the global registry, there is a concept implemented in z3c.baseregistry. It does exactly what the changes forces to do without the possible sideeffect of register non peristent actions in a local persistent component registry. With some lines of ZCML every action could register it's handler to such another global component registry. e.g. utility component=my.global.Registry provides=zope.component.interfaces.IComponents name=other / zope:registerIn registry=my.global.Registry !-- include your ZCML here -- /zope:registerIn Now, if your site provides the 'other' IComponents utility, your fine and you will get what you need. This concept explicit allows to register components in a component registry and does not invoke a running application in any way. In my point of view, this changes/feature is implemented as simple as possible and not done right. If you configure a system during startup, in our case with ZCML actions, it's really not a good idea to change the running system itself for make this possible. Another point, reloading ZCML actions after a system startup e.g. from the UI is probably not possible anymore. Then we whould have to call setSite(None) and this, on a running system, whould force to loose the local components registry at the same time.

[Zope-dev] zope.component.zcml and global registry
Hi folks, the ZCML directives in zope.component register components using the utility method handler, which looks like: def handler(methodName, *args, **kwargs): method = getattr(zope.component.getGlobalSiteManager(), methodName) In our company-specific framework (which is far far from zope3, and only uses the bicycle repair kit), we use different registries per application, similarly to repoze.bfg. Everything works, included code which relies on the zope.component's API, thanks to the hooks on getSiteManager. Those ZCML directives use the getGlobalSiteManager though, which is not hookable and thus we had to reimplement the ZCML directives we need to call getSiteManager instead of getGlobalSiteManager. By default, getSiteManager returns the global registry, so I don't see any obvious reason why the ZCML directives make use of getGlobalSiteManager. repoze.bfg, for example, reimplemented the ZCML directives as we did, but I'd love to be able to use the implementation from zope.component. Any idea?

The worst thing what could happen that the changes in getGlobalSiteManager will add the configuration to the local site. btw, we do something like this in a bootstrap subscriber: def bootstrapXPOSite(event): Subscriber to the IDataBaseOpenedEvent Setup a site as root Application db, connection, root, root_folder = getInformationFromEvent(event) if root_folder is None: # create import bla.bla root_folder = bla.bla.Site(u'The only site') zope.event.notify(zope.lifecycleevent.ObjectCreatedEvent(root_folder)) # add as Application root root[ZopePublication.root_name] = root_folder # commit site to DB transaction.commit() connection.close() zope.event.notify(DatabaseOpenedWithRoot(db)) If all kind of configuration directive processing is done before any kind of DB root access and relevant event handling (e.g. site hook setup) this seems fine to me.

I've tried the patch running the whole ztk test set (including the zopeapp test set) and there are no regressions, so I assume it is safe to apply it to the trunk. I'll wait a week to see if anybody objects to this change, then I'll commit it to the trunk.

If the tests all pass, then I would say go ahead and commit it now, but add tests to verify that the new feature works as you expect.
