Soliciting feedback before calling a 1.0 release of Atomos

Hi,

I would like to give you a chance to provide feedback before calling a vote
for a 1.0 release of Atomos.  I've done a few modifications over the past
week or so and have improved the project readme to make it easier to
understand what Atomos is and how to use it:

https://github.com/apache/felix-atomos

Please let me know what you think and provide any improvements that you
think may be needed before we call for a 1.0 release.

Thanks

Tom

Hi Karl,

works ... works ... works ...

when executing from atomos.examples.substrate.lib/target/ dir, then it
works fine !

regards
Pierre

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Thomas Watson <tj...@gmail.com>.

Hi,

Yes that is another reason the lib solution is not great.  It has to find
the folder where the bundles are.  Currently it tries the current
working directory to find that.

I'll update the readme for that example to make it clear.  I'm also going
to update the recommended graal version.  I finally did get big sur to get
graal to work again.  I tested 21.0.0.1 (just released) and it appears to
work.  Note that on Mac jlink is broken so it fails building the jlink
example on graal.

For others trying to get Graal to work on Mac Big Sur.  I had to do a fresh
extract of the tar.gz and then run:

 sudo xattr -d -r com.apple.quarantine path/to/graal/dir

I had to do that before invoking any executable from graal.

Tom

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Karl Pauls <ka...@gmail.com>.

Hi Pierre,

ah, I think this is a funny coincidence. The example was indeed broken
but that is not the problem you are running into I think.

Can you cd into the target dir and try again? I.e.,

cd atomos.examples/atomos.examples.substrate.lib/target
./atomos

The substrate.lib example needs to be executed from the same dir the
executable is in - we probably need to point that out in the
documentation!

regards,

Karl

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Pierre De Rop <pi...@gmail.com>.

Hi Tom,

no, I'm sorry but the substrate.lib does not work either with -Pequinox in
my environment.

Hi Karl,

I recompiled the latest version using "./mvnw clean install -Psubstrate
-Pfelix", so it's the same:the substrate.lib sample does not work. it shows
the harmless UnsupportedFeatureError error (this, I know I can ignore it),
but it does not work.
Other examples seem to work fine, so I don't want to block the release
since Tom said that the substrate.lib example should not be promoted
anymore ...

PS: I re-installed the old GraalVM CE 20.2.0, to make sure I'm using the
same version that is documented from the atomos readme files.

thanks.

regards
/Pierre

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Thomas Watson <tj...@gmail.com>.

Strange, I really remember testing that change across both felix and
equinox on substrate.  Thanks for fixing it.

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Karl Pauls <ka...@gmail.com>.

Hi Pierre,

good catch, the latest refactoring [0] removed the dependency for the
log service. I added it back in [1] - can you try again?

We need better tests for the substrate examples - they are hard to
test and really don't like when something is missing :-)

You'll still see the:

java.lang.reflect.InvocationTargetException
...
Caused by: com.oracle.svm.core.jdk.UnsupportedFeatureError: Defining
new classes at run time is not supported. All classes need to be known
at image build time.
...
com.oracle.svm.core.jdk.UnsupportedFeatureError: Setting a custom
URLStreamHandlerFactory.

for Felix but that is just a print out which is harmless.

regards,

Karl

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Thomas Watson <tj...@gmail.com>.

Hi,

Does it work with -Pequinox?  I think the exception you see in
org.apache.felix.framework.ext.ClassPathExtenderFactory is expected and
doesn't cause the problems, but I am unsure why the substrate.lib example
isn't working for you.  The unresolved bundle exception is benign.  It is
just the example pulling in the
org.osgi.service.component.annotations which is unresolvable.  The other
exceptions from org.apache.felix.framework.URLHandlers are again expected.
Karl has looked at ways to avoid these errors, but I don't think he found a
way to stop them from being thrown in the output/log.  To be honest the
substrate.lib example is not something I think we should promote though.
It requires a lot of manual configuration and requires the bundles compiled
in the image also be available in a "lib/" folder for resource lookup.  The
maven example is much better because it auto configures things like the
reflection necessary for Declarative Services and BundleActivators and it
indexes all the resources into the image so you don't need a lib/ folder to
hold the bundles.

Unfortunately I updated to Big Sur on my Mac this week and now Graal is
completely non-functional.  Not sure how long it will take me to get to a
working state with Graal again.

Tom.

Re: Soliciting feedback before calling a 1.0 release of Atomos

Posted by Pierre De Rop <pi...@gmail.com>.

Hi Tom,

Maybe I did something wrong, but it seems I can't run the
substrate.lib/target/atomos example.

So, I'm using this graalvm version:

openjdk version "11.0.10" 2021-01-19
OpenJDK Runtime Environment GraalVM CE 21.0.0 (build
11.0.10+8-jvmci-21.0-b06)
OpenJDK 64-Bit Server VM GraalVM CE 21.0.0 (build 11.0.10+8-jvmci-21.0-b06,
mixed mode, sharing)


Now, I have built the whole project using this command, as per your README
from [1].

./mvnw clean install -Psubstrate -Pfelix


So, after a while, everything is built, but when I'm trying to launch the
following executable:

./atomos.examples/atomos.examples.substrate.lib/target/atomos

then I'm getting this exception:

And, I don't get the gogo prompt and I can't hit the gogo web console from
http://localhost:8080/system/console/bundles

Did I wrongly build the projects ? maybe it's because I'm using the
latest GraalVM
CE 21.0.0 version while in your README file it is mentioned that GraalVM CE
20.2.0 is required ? Notice that I'm getting the same issue when using the
-Pjava8 option. I hope I'm not raising a false alarm ?

Now, the other  atomos.examples.substrate.maven works, but at startup, I
however noticed some exceptions:

./atomos.examples/atomos.examples.substrate.maven/target/native_image_build/bin/org.apache.felix.atomos.examples.substrate.maven

Despite of the exceptions, the substrate.maven example works fine: I can
get the gogo prompt and the webconsole also works.

Posted by Thomas Watson <tj...@gmail.com>.

Hi,

I did publish the new snapshots of atomos to
https://repository.apache.org/content/repositories/snapshots in case you
want to try them from there. I also updated my simplistic example of gogo
w/ atomos at https://github.com/tjwatson/atomos-examples

Thanks Tom for the reminder !

I should have time to test by the end of the week.

I think Atomos has made great progress and I am looking forward to the release!

I'd like to encourage people on this list to go and play around with
it. If you still want to have some API changes now would be the time
to bring it up but regardless, I think having a look will be
worthwhile no matter what - cause it is really nice :-)

regards,

Karl
