Bas updated ARIES-1357:
-----------------------
Attachment: test-cases-1.patch
The attachment 'test-cases-1.patch' provides two test cases that can show
issues with:
1) The current preferred provider implementation which does not compare
correctly anymore
2) The subsystem resource installer which should first install shared resources
before the child subsystems
3) Optional dependencies ending up in a resource of synthesized type that is
persisted in the deployment manifest eventually causing problems on restart
For all of these issues patches have been provided (the synthesized patch in a
different jira task)
On a side note, how can I debug with pax exam? I tried to get something to work
to get some more information from the test cases but I could not get debugging
working in eclipse.
> BasicSubsystem can be used by the subsystem install process a factor 6 times
> faster

> The problem was poor performance while installing a subsystem on a container
> with 200+ subsystems installed.
> While doing performance analyses on the subsystem install process we noticed
> the BasicSubsystem is working a lot with its manifest instead of
> pre-calculating data that is used a lot.
> While using the pre-patch version of BasicSubsystem a subsystem install
> (while having 200+ running subsystems) could take more than a minute. While
> using the patched version where we pre-calculate highly used data when a new
> subsystem manifest or deployment manifest is set we could bring it down to 10
> seconds. We only pre-calculated the data that was highly used.
