Re: [platform-update-dev] Couple of Questions about Update...

Couple of notes I sent on update-dev...  hopefully there is a solution to
the download server problem.

Dejan,

Thanks for the quick response.

1) I will wait for Christophe on this, since I haven't been able to puzzle
it out yet.

2) I agree that the numbers should increment.  It was just a fluke that I
was using it this way, but it might still be useful to give some UI
indication that nothing was done for "plugin X" because it is already up to
date.  I suppose that could be somewhat clumsy if it popped up in the
middle of a large update (I was just doing one plugin).  Perhaps some kind
of "Update Summary" report that lists plugins that were/weren't upgraded
when the process is complete.  Could be useful.

3) If I ever get bored with my current projects I would like to work on
that one.  I'll let you guys know if I do :)  Right now I have a full plate
w/ my other plugins and my "real job".

Andrew,

Thank you for the kind words. Answers:

1) I think that you can point at other servers from site.xml - I will let
Christophe Elek confirm that one.

2) Update uses versions to compute differences and see if something is
'newer'. You can use four-point identifier for build-to-build changes (e.g.
1.0.0 v20020921). The fourth segment is a label that is compared
lexicographically so dates are good candidates there because newer date
comes up as 'newer' in Update. We consider plug-ins with the same ID and
version the same and do not download them in order to increase performance
(we only download 'delta').

3) There is an extension point 'org.eclipse.ui.startup' that registers a
plug-in that will run on startup. You will need to use Update Core APIs to
find out what features are currently active, go to their update sites and
see if there are new versions available. We will eventually provide this
capability in Update but you can write your own before us (we will need to
shuffle code a bit because we would need to move our search classes from
the Update UI to this new 'startup' plug-in).
