[equinox-dev] equinox state and resolver

Hi,

 

I was playing around with the Equinox resolver and state and observed something that confused me.

 

I get a state object from PlatformAdmin and add some bundle descriptions that I know won’t be able to resolve – for example they trigger a “uses” conflict.

I call resolve and after that isResolved(), which returns true.

If I go through the bundle descriptions in the state and check them I’ll be able to retrieve the resolver error for the uses conflict and that particular bundle description will return false for its isResolved() method.

I found that strange so I checked the javadoc for State’s isResolved method and found it “Returns true if there have been no modifications to this state since the last time resolve() was called.”.

This puzzled me even more, after all I included some descriptions in that State.

 

In Virgo for the quasi resolve to catch resolver errors early, we check the bundles descriptions for resolver errors and don’t call the isResolved method of the State, which works fine.

But it made me curious about how the State is expected to work and in order to get a resolution result which is the best approach.

Can you share some technical background? :)

 

Best Regards

Borislav
