Followup on getting felix scr commands to show up in karaf
Hello all,
Over in this thread the gogo'ness of SCR is discussed:
http://karaf.922171.n3.nabble.com/getting-felix-scr-commands-to-show-up-in-karaf-td2257486.html
I'm stuck in the same problem where my SCR bundle loads and all my services
are properly satisfied and injected but the scr command itself is not
available.
Guillame you remarked:
> Actually, I've just made some tests and the commands are functional even
if they don't appear in the <tab> completion
I was hoping you could elaborate a little more about this. Are you saying
that you were able to get to the scr command in the karaf> prompt? Or were
you simply remarking that scr worked wrt injection and that the commands
just weren't functional?
I recognize that this ticket is still out there:
https://issues.apache.org/jira/browse/KARAF-397
And I see the priority is MAJOR. Question to the devs: is this something
you expect will be fixed soon?
I want to go to Karaf 2.2.0 but the lack of a scr command is going to give
my developers a lot of heartache....
Thanks for your time,
-c

Posted by mikevan <mv...@comcast.net>.
Chris,
In my research, I've learned that SCR is a way of deploying bundles without
needing a bundle activator. If this is why you're using SCR, I wonder how
much trouble it would be to simply transition your bundles to use Blueprint
(yeah!) or SpringDM (meh).
In any case, in the 2.2.x branch of Karaf, I've been able to access all of
the requisite SCR commands. As Guillaume points out, those commands don't
have support for tab-completion or listing using tab-tab.
There are other core felix commands such as "tac"; which, although
implemented in Felix, needed to be re-implemented in Karaf to be used. I
wonder if this needs to be done with SCR commands as well.
What I hope the Karaf community can do is let me know if I need to
re-implement the SCR commands in Karaf to make them available for
tab-completion and inclusion in the tab-tab list.

Re: Followup on getting felix scr commands to show up in karaf
Posted by Christoper Blunck <ch...@thebluncks.com>.
Hi Mike,
Yup. As Guillaume mentioned the change is that SCR trunk still uses
the old shell infrastructure rather than GoGo. It looked like there
was a single file that needed to be updated for SCR (specifically the
shell bindings) and modified to use GoGo rather than the old shell
stuff.
Any help you could give would be great! It gets old dropping my
features into 2.1.x so I can verify all the services come up and are
available!

Re: Followup on getting felix scr commands to show up in karaf
Posted by mikevan <mv...@comcast.net>.
I'd like us to re-address this issue with getting scr commands being useful
in Karaf. I've tested them on the trunk, and after installing the latest
version of SCR on Karaf-trunk, there isn't access to any of the scr
commands. I'll be researching this over the weekend, but any pointers you
can give me would be helpful.
Previously in this thread there was the idea of some sort of "bridge" being
developed that would allow Karaf console usage of the scr commands. Could
someone shed more light on what this actually means? Are we talking about
creating a new set of scr shell commands and then installing them as part of
a felix-scr feature?

That's the expected behavior. Command themselves work but not completion.

Re: Followup on getting felix scr commands to show up in karaf
Posted by Christoper Blunck <ch...@thebluncks.com>.
Hi Guillaume-
Thanks for giving me some troubleshooting techniques. I ran the osgi:ls
command and here is a snippit of the output:
Apache Felix Declarative Services (41) provides:
------------------------------------------------
org.osgi.service.cm.ConfigurationListener
org.apache.felix.scr.ScrService
org.osgi.service.cm.ManagedService
org.apache.felix.scr.impl.ScrGogoCommand
That last line suggests to me that the command itself has been registered.
Interestingly enough "scr list" fails but "scr:list" succeeds:
karaf@root> scr list
Command not found: scr
karaf@root> scr:list
No components registered
When I do a "tab-tab" at the karaf@root> prompt I see a bunch of commands I
can execute (which is expected). However, scr:list is not in that list.
Here are the commands starting with s that are available to me:
set shell:cat
shell:clear shell:each shell:echo
shell:exec shell:grep shell:head
shell:history shell:if shell:info
shell:java shell:logout shell:more
shell:new shell:printf
shell:sleep

I am really in over my head wrt gogo and the rest of the shell framework
stuff so I'm not quite sure what to do next.
Do you have some ideas of what is going on?
I'd be happy to help you troubleshoot some more but I don't know how much
more valuable I'd be at this point...
Thanks again for your time - I do appreciate it.

Re: Followup on getting felix scr commands to show up in karaf
Posted by Guillaume Nodet <gn...@gmail.com>.
As you noticed, scr 1.6.0 use the old felix shell which is different
from gogo, so that won't work unless there's a bridge somewhere.
For scr trunk, not sure why it doesn't work. Can you first check if
the command is actually registered in the registry using the osgi:ls
karaf command ?
If the command is registered but isn't available, that's a bug in
Karaf console. If the command isn't registered, a suspect an
exception to be thrown in the ScrCommand#register() method.

Re: Followup on getting felix scr commands to show up in karaf
Posted by Christoper Blunck <ch...@thebluncks.com>.
Hmmm... I don't believe I'm trying to use a karaf feature on top of a gogo
command.
I'm just trying to run the scr:list command without using tab completion or
anything.
Steps to reproduce:
1.) Download and untar:
http://www.apache.org/dyn/closer.cgi/karaf/2.2.0/apache-karaf-2.2.0.tar.gz
2.) Start up karaf bin running "cd bin; ./karaf"
3.) Download into the deploy directory:
http://www.gossipcheck.com/mirrors/apache//felix/org.apache.felix.scr-1.6.0.jar
4.) type "scr:list" or "scr list" at the prompt. You'll get command not
found.
A couple of things I've noticed...
Here's the source code for the bundle activator for SCR in version 1.6.0:
http://svn.apache.org/repos/asf/felix/releases/org.apache.felix.scr-1.6.0/src/main/java/org/apache/felix/scr/impl/Activator.java
Note that in the start() method there's a try-catch around the part where
the ScrCommand is registered. I added a debug statement to the catch
section and found out that there was a NoClassDefFoundError on
org.apache.felix.shell.Command
when the code was trying to register the ScrCommand. I downloaded
org.apache.felix.shll.command 1.4.2 and put it my deploy directory. That
made the NoClassDefFoundError go away but it still did not make the "scr
list" command work. I still got a "command not found".
Also ... It appears the trunk of SCR has been updated to work with gogo:
http://svn.apache.org/repos/asf/felix/trunk/scr/src/main/java/org/apache/felix/scr/impl/Activator.java
The start() method looks different and the comment suggests it now works
with gogo.
I pulled the trunk and compiled it. I then tried to run karaf with
org.apache.felix.scr-1.6.1-SNAPSHOT. DS started but I still didn't have my
"scr list" command.
Any ideas?

Re: Followup on getting felix scr commands to show up in karaf
Posted by Guillaume Nodet <gn...@gmail.com>.
Let's be clear about that. There's no reason why the scr or any gogo
commands would not work in karaf.
What does not work is karaf features on top of gogo such as completion
(both command and parameter).
If that's not the case, this should clearly be fixed asap.
