[Slices] and dm Server M5

[dsklyut]

Can Slices be used with M5? If not, how soon?

[dsklyut]

I found dms-m5 branch and that thing just worked!

If anyone is interested:
1. pull down and build dms-m5 branch from slices repo

git checkout --track -b branch dms-m5 origin/dms-m5

2. build it

cd build-slices
ant clean jar package

3. modify $SERVER/config/com.springsource.kernel.properties

#deployer.systemArtifacts=	repository:plan/com.springsource.server.web
deployer.systemArtifacts=	repository:plan/com.springsource.server.web,repository:plan/com.springsource.osgi.slices

4. start dm Server

I ended up testing this with a petclinic sample app. To build that I had to add

		<dependency org="org.eclipse.osgi" name="org.eclipse.osgi" rev="${org.eclipse.osgi}" conf="compile->compile"/>

in /samples/slices-petclinic/com.springsource.slices.petclinic.host/ivy.xml

Will follow up if I see issues with my own apps.

Further observations:

Application configured in a scoped plan with a host webapp and 1 slice, does not deploy right now.

Looks like slices deployer is not used to deploy a slice, but a regular web-app deployer is. Seeing msg in console:

[2009-10-14 11:24:02.698] Thread-2                     <WE0000I> Starting web bundle '****plan-1.1.0.DEV-SNAPSHOT-****.web' context path '/****.web-1.1.0.DEV-SNAPSHOT'.

Looks like manifest entries for slices are not picked up.
I guess just dropping a slice plan into pickup is not enough.

Dmitry, first of all, I should say thank you for trying this out on M5: you've pretty much written my blog post on how to use Slices on M5 for me!

Using a Slice from within a scoped plan should work. If it doesn't, then it sounds like you found a bug. Apologies for that. My guess would be that it's the scoping logic that's causing the problem. Does it work for you if the plan is not scoped?

A little further research:

1. Transformer ordering is not correct (I think).
SliceTransformer is executed before PlanResolver. So I bumped ranking of SliceTransformer by 1.

2. There is still an issue described in http://forum.springsource.org/showthread.php?t=74704.
Matching host bundle name to bundle.symbolicName is broke again.

Created DMS-1756 and updated DMS-1134

One final issue:

When dm starts up with slices, you can see a message for com.springsource.server.web plan - Install failed. Is that because slices pull in classes from com.springsource.server.web plan and bundles are started by the time com.springsource.server.web is processed?

I tried changing the order in com.springsource.kernel.properties, but the same message in the logs. Everything works, but just not pretty.

deployer.systemArtifacts=	repository:plan/com.springsource.server.web,repository:plan/com.springsource.osgi.slices

and

deployer.systemArtifacts=repository:plan/com.springsource.osgi.slices, repository:plan/com.springsource.server.web
