Re: [equinox-dev] Eclipse Oxygen(4.7) M5 available

[Todor Boev <rinsvind@xxxxxxxxx>]

Answering myself:

- In Oxygen p2 publisher will not parse the Require-Capability/Provide-Capability manifest headers.

- The support for generic reqs/caps is limited to p2.inf files that need to be maintained manually.

- The p2 internal representation of a capability is limited to the (namespace, name, version) triplet.

- Therefore it is not possible to express the full information contained in the bundle manifest via p2.inf or generally in p2. 

  The users need to select one most meaningful capability attribute and map that to the p2 model.

After a lot of digging through the p2 code it seems that:

- The internal representation of a requirement can already match against capabilities using an LDAP filter.

- Therefore there is hope for a generic solution if the internal representation of a capability is extended to support an attribute map.

I noticed that in Oxygen M1, p2 was extended to support some generic capabilities/requirements:
https://www.eclipse.org/eclipse/news/4.7/M1/#Equinox

I have two questions:
- Does this mean p2 now has a mechanism to support the general OSGi capability/requirement model? (i.e. where a capability is a set of properties and a requirement is an LDAP filter)

- Why are only "osgi.service" capabilities added? Should't there be also "osgi.implementation" capabilities?
