> Key: SLING-709
> URL: https://issues.apache.org/jira/browse/SLING-709
> Project: Sling
> Issue Type: Improvement
> Components: JCR Install
> Affects Versions: JCR Install 2.0.4
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: JCR Install 2.0.4
>
>
> The BundleResourceProcessor employs a mix of bundle management and package
> admin tasks, which may cause the framework to get into uncontrolled states:
> (1) installOrUpdate may update existing bundles. This causes the bundle to be
> stopped, updated and started
> (2) processResourceQueue calls PackageAdmin.resolve for installed bundles
> (3) processResourceQueue starts resolved bundles
> (4) processResourceQueue calls PackageAdmin.refreshPackages repeatedly
> This all calls way to much into the framework bundle resolution and may be
> greatly simplified and stabilized:
> (1) when a bundle is to be updated it should be stopped before being updated.
> It will be started later
> (2) processResourceQueue only calls refreshPackages if bundles have been
> uninstalled or updated since the last processResourceQueue
> (3) if packages are refreshed the BundleResourceProcessor waits for the
> refresh to finish and starts any bundles stopped during package refresh as
> well as newly installed and updated bundles and lets the framework decide on
> resolution.
