[cross-project-issues-dev] Coexistence of Update Manager sites and P2 re

[David M Williams <david_williams@xxxxxxxxxx>]

I hope the list doesn't mind mere "how
to use" question to this list ... but, figure it may impact several
projects, so figured it'd be a good place to discuss. 

And, there's actually several questions.


With the old update manager technology,
when we wanted to test the "get updates for existing features"
_before_ the updates were actually at the production site, we could use
a site policy file to "trick" update manger into looking elsewhere
for the updates to existing features (namely, it'd look on the test site
listed in the policy file). 
(See http://wiki.eclipse.org/Using_Policy_Files
for how to do this). 

So, question 1: Does P2 offer this same
sort of thing? Does is allow a "policy file" of some sort? (I
don't see the User Preference as their used to be, but figure maybe the
concept is still there, but implemented differently?. 

Question 2: Any "tips or tricks"
on managing a site for both Update Manager and P2 Updates ... in other
words, a site that contains upgrades for both Europa and Ganymede?  We
in WTP have always strived to have one update site "for everything
released". I know technically the same site can act as a UM site,
and a P2 repository, I'm just wondering if anyone has tested this yet ...
or, if there will be any complications we should plan for? In particular,
what we want is that if a user with Europa based product goes there for
updates to their existing Europa features, that it will be obvious to them
what to get, and they won't be confused and accidentally try to update
to the Ganymede version of everything. 

Question 3. I guess question 2 begs
the additional question ... is it expected, or has anyone tested, having
a Europa installation, and then update everything to Ganymede?  This
was asked a long time ago .... see bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=223434
... any volunteers? Or anyone tried it yet? 
Please update bug 223434 if you have.


Thanks,
