Hi Harini,

great to see that you are working on bringing Kura up on Concierge and welcome to the Concierge community!

As Jochen said, he is also looking into this and will quite possibly be able to help you.

Regarding xargs, this is a bit of a legacy thing. I used it for Concierge R3 to have a drop-in replacement for Knopflerfish. Currently I more often use a launcher Java class but in principle the xargs mechanism should still work. I will check why bundles don't start when using -istart.

Regarding performance, I have some older performance tests but really need to write some new tests. Right now my main focus is on fixing the last few test cases to be fully R5 compliant but quantifying the runtime behavior to guide optimization is right next on my agenda. I would say that right now Concierge is already pretty fast especially on smaller devices where I have tested it a lot but there are still some areas where I think we can do (even) better.

Best regards,

Jan.

Hi,

I am currently working on the GSoC project Port Eclipse Kura over Concierge . I am using the code from http://git.eclipse.org/c/concierge/org.eclipse.concierge.git to build my concierge runtime bundle. There are a few issues I come across when porting the kura application from equinox over to concierge. Hope someone here can help me.

- Bundle start order : I have configured my init.xargs file to start bundles using -istart property. However I find that the kura bundles install but do not start until i issue the start command in the concierge shell. Is this due to a concierge implementation to conserve resources?
- Declarative services : Kura uses org.apache.felix.scr for implementing declarative services. How can I best port that implementation over to concierge?

Also are there any tests for measuring the performance of a bundle running over concierge? 


Thanks in advance.
