------------------------------------
Summary: Sharing policy is importing from requirements not
included as part of the subsystem
Key: ARIES-1666
URL: https://issues.apache.org/jira/browse/ARIES-1666
Project: Aries
Issue Type: Bug
Components: Subsystem
Reporter: Thomas Watson
When resolving a subsystem the implementation uses the Resolver service to
determine the subsystem's dependencies. For application type subsystems this
causes the sharing policy to be computed according to the wires returned by the
resolver.
The subsystems implementation is doing a 'full' resolve to do this. This
includes re-resolving bundles already resolved in the system repository as part
of the subsystem resolution or installation process. As a result the
resolution map used to calculate the import sharing policy contains wires for
many resources that are not considered as part of the subsystem content. But
the import policy is updated with the requirements for all wires which do not
get wired to a provider contained in the subsystem.
This results in a explosion of filters in the equinox region edge which
connects the subsystem region to its parent region. This is bad for several
reasons. 1) may give access to things that the subsystem should not have
access to 2) will slowdown performance when the list of filters gets large.
