I'm cleaning up Products.remember, and want to make the way it changes
the Site Setup Users and Groups (@@usergroup-userprefs) configlet less
disruptive. In general, can products substitute different page
templates for standard Site Setup configlets without permanently
changing it for all portals in the zope instance?
The latter is what Products.remember is currently doing, replacing the
standard usergroup-userprefs template with its own via an
overrides.zcml. There are two big problems with this - it affects all
the portals in the Zope instance, whether or not Products.remember is
quick-installed, and it is permanent, lasting after Products.remember
has been removed entirely from the system.
I have not looked at the code, but I find this part hard to believe. If
Products.remember is removed from the system then its overrides.zcml
cannot be loaded anymore so the default behavior returns, right?
Since I don't know why that approach was taken, i'm unsure about
whether less disruptive approaches would work. Don't products
sometimes have to offer different versions of standard control panel
configlets? What's the right way to do it?
This approach was probably taken because it is the easiest approach:
just assume there is only one Plone Site and that no one adds
Products.remember unless he really wants to install and use it.
The usual way to get more control over this, is by moving whatever is in
the overrides.zcml to a normal configure.zcml and registering it for
your own browser layer (see the plone.browserlayer package).
Guidance would be greatly appreciated! I've checked in several
Products.remember fixes to the collective, including Plone 4 and
Products.membrane 2 compatibility, integration of someone else's
email-login provisions, a substantial part of uninstallation, and
more. This, plus an upgrade step to undo the effects of the
overrides.zcml, are the main obstacles i'm facing before packaging up
the changes for release.
Great, thanks!
