Re: A story about QuickInstaller and GenericSetup cooperation

You have uncovered my secret master plan. ;-)

Well, not really, but getting rid of CMFQuickInstallerTool might be an 
option in Plone 5.1 or 6.0. The QI is more and more just a different way 
of talking to portal_setup.

What QI now mostly does, is:

- QI is an alternative installation system, with Extensions/Install.py. 
  Products depending on this would need to be changed to use GS.  In the 
basis this is not hard.  I expect any product that was created for Plone 
3 or higher to have a GS profile.  Some old products, like 
Products.Marshall, would need a small profile, which could very roughly 
be: move Extensions/Install.py to setuphandlers.py and hook it up in zcml.

- QI determines a link between a profile and its product and the other 
way around.  And in the near future maybe a link between an uninstall 
and a default profile.  The logic behind those links could in Plone 5 be 
moved to the new controlpanel/browser/quickinstaller.py.

- QI keeps track of which products are installed.  But when done 
correctly (see the TODO items in my original post) this information can 
be found in GS as well.

- QI keeps a list of which things have been added during the install: 
skin layers, tools, etc, so it can automatically remove them during 
uninstall.  It more or less works, but it does not do everything.  With 
QI gone we would loose this.  An uninstall profile would basically 
become mandatory for add-ons.  When an uninstall profile is not found, 
the Add-ons control panel would need to display a big fat warning, 
probably already before activating the product: "This product has no 
uninstall profile: if you activate it you are stuck with it for 
eternity."  Put a button next to it: "I feel lucky." ;-)
