Re: Karaf 4.2.1, 4.2.2 ( build from Git ) - Feature install blocked - condition race ( ? )

[Jean-Baptiste Onofré]

You should use feature:install -v -t to get details and simulation.

HI JB,

this can be, I would have to check for each feature, but as said: when porting from Karaf 4.0.9 to 4.2.2, I guess this would have to be addressed more verbose -- some kind of warning message or something.

I will re-create feature file with suggested changes, but I stopped using dependency/prerequisite attributes, as I found out I ran into different set of problems.

I had this kind of problems, when setting up JPA datasource - as conumers complaint to on start on missing datasource - but bundles installed and started.

It is "strange" when command "feature:install foo" does not return to terminal and there is no message in log file.

Thanks, kind regards,
Miroslav

    Hi

    the resolver behavior is not exactly the same if you do:

    feature:install foo

    or

    feature:install jms bar foo

    If you feature expects another feature providing a service, than,
    the "dependency" feature should be completely installed and
    started to provide the services before your feature is install.

    For instance, if you have:

    <feature name="my" version="xx">
        <feature>foo</feature>
        <bundle>mvn:my/my/xx</bundle>
    </feature>

    If "my" bundle has a requirement to a service provided by foo,
    then, you can have an issue as foo can be installed async. So, in
    that case, you should first install and start foo first. You can
    achieve this using prerequisite flag:

    <feature name="my" version="xx">
        <feature prerequisite="true">foo</feature>
        <bundle>mvn:my/my/xx</bundle>
    </feature>

    Do you think you are in this case ?

    Regards
    JB

    Hi giys,

    I am tracking mailing list last few weeks, can be, I missed some
    mails.

    So, I think I have similar issue that what reported few days ago
    from Thiago, with title "Unable to deploy a Karaf kar file
    containing a ComponentFactory OSGi declarative service".

    I have application porting from ServiceMix 7.0.2 ( build from
    ServiceMix GitHub master ) to Karaf 4.2.x ( fist 4.2.1 and now
    4.2.2, both Github source ).

    I have application in multiple Karaf Features. In ServiceMix
    7.0.2 ( Karaf 4.0.9 ) I install application with on "super
    parent" feature, that is a tree of features ( XSD Feature
    namespace 1.0 ), so without dependencies or prerequisite attributes.

    Same set of features, when deployed in Karaf 4.2.x is "blocked",
    it stops in different steps, at different features. But this is
    in features of pre-defined features, like JMS, JPA, Hibernate,
    ActiveMQ, ...

    Strange thing is, when I install one single feature at a time it
    works. For example ( there is multiple such feature groups, just
    one here ):

    <feature name="my-infrastructure-requirements-jms"
    version="${project.version}">
    <feature>aries-blueprint-spring</feature>
            <feature version="[4.2.2, 5)">shell-compat</feature>
            <feature version="[5.15.7, 6)">activemq-broker</feature>
            <feature version="[5.15.7, 6)">activemq-cf</feature>
            <feature version="[5.15.7, 6)">activemq-blueprint</feature>
    
<bundle>mvn:org.apache.servicemix.activemq/org.apache.servicemix.activemq.camel/7.1.0-SNAPSHOT</bundle>
    
<bundle>mvn:org.apache.servicemix.activemq/org.apache.servicemix.activemq.service/7.1.0-SNAPSHOT</bundle>

            <feature version="[4.2.2, 5)">jms</feature>
            <feature version="[2.23.0, 3)">camel</feature>
            <feature version="[2.23.0, 3)">camel-spring</feature>
            <feature version="[2.23.0, 3)">camel-jms</feature>
            <feature version="[2.23.0, 3)">camel-blueprint</feature>
            <feature version="[2.23.0, 3)">camel-cxf</feature>
            <feature version="[2.23.0, 3)">camel-jpa</feature>
            <feature version="[1.0.2, 2)">pax-jms-activemq</feature>
            <configfile
    finalname="/etc/org.apache.servicemix.activemq.service.cfg">
    
mvn:org.apache.servicemix.activemq/org.apache.servicemix.activemq.service/${project.version}/cfg/activemq-service
            </configfile>
    </feature>

    So almost always it stops somewhere when installing this feature,
    but when I install it one by one -- it works. ( it never
    installed when installing "feature groups", this is the "feature
    group" it stops most of the time, other is JPA related "feature
    group" ).

    so: feature:install my-infrastructure-requirements-jms

    has message in log:
    2018-09-05T09:16:08,539 | INFO  | pipe-feature:install
    my-infrastructure-requirements-jms |
    FeaturesServiceImpl              | 11 -
    org.apache.karaf.features.core - 4.2.2.SNAPSHOT | Adding
    features: my-infrastructure-requirements-jms/[2.0.0,2.0.0]

    That is all there is ... and it waits here, for ever. So it seems
    there is really a condition race. So when I saw mail from Thiago,
    I am even more sure, this is true.

    Here is full feature file. Please note, I have some features, to
    "fix" feature install order - spring is a mess, as it starts to
    install version 5, as "best one" but this is not the case for me
    - as I want to use ActiveMQ. ( you can see I also use "future"
    version of ActiveMQ 5.15.7 - my own build with updated versions
    of dependencies in ActiveMQ, same behaviour is with "stock"
    version, so I do not see problem in this ). Other issue ( was )
    with Jetty version 9.4.10 and 9.4.11, but this is fixed no in Karaf.

    Also ServiceMix 7.1.0-SNAPSHOT is my own build of source code
    from 7.0.2-SNAPSHOT, to re-use ActiveMQ connection factory ( this
    is Servicemix 7.0.2 with updated Camel version ).

    Here I use feature xsd namespace 1.4.0

    If you need some more info, please let me know. ( this feature
    file is "a mess", as I did not know what is wrong ... so no need
    to judge it for its beauty please :D :D )

    I am building ActiveMQ, Camel, Pax, Karaf, Hibernate ... SNAPSHOT
    versions daily and testing it.

    Kind Regards,
