Communication via topics does not work after transitioning from Ice 3.5 to 3.7

ptriantdptriantd Member Pavlos TriantafyllouOrganization: PersonalProject: Robotics SW

Hi everyone,

After upgrading to Ubuntu18.04 and Ice 3.7, creating a topic publisher fails with src/Ice/Reference.cpp:1643: ::Ice::NoEndpointException: no suitable endpoint available for proxy IceStorm/TopicManager -t -e 1.0 Aborted (core dumped)

Communication via proxy works fine though!

I am thinking that this might have to do with some configuration issue due to upgrading from 3.5 to 3.7.

My configuration is as follows:

config.registry

IceGrid.InstanceName=IceGrid
Ice.Default.Locator = IceGrid/Locator:tcp -p 4061
Ice.Trace.Network = 1
IceGrid.Registry.Client.Endpoints = tcp -p 4061
IceGrid.Registry.Server.Endpoints=tcp
IceGrid.Registry.Internal.Endpoints=tcp
IceGrid.Registry.LMDB.Path=db

IceGrid.Registry.PermissionsVerifier=IceGrid/NullPermissionsVerifier
IceGrid.Registry.AdminPermissionsVerifier=IceGrid/NullPermissionsVerifier

IceGrid.Registry.DynamicRegistration=1
IceGrid.Registry.SessionTimeout=300
Ice.MessageSizeMax=10000000

IceGrid.Node.CollocateRegistry=1

IceGridAdmin.Username=foo
IceGridAdmin.Password=bar

config.node

Ice.Default.Locator = IceGrid/Locator:tcp -p 4061

IceGrid.Node.Name=Node1

IceGrid.Node.Endpoints=tcp
IceGrid.Node.Data=data

Ice.Trace.Network=1

application.xml

<icegrid>

  <application name="Demo">

   <server-template id="IceStorm">
     <parameter name="instance-name" default="IceStorm"/>
     <parameter name="topic-manager-endpoints" default="tcp -h localhost"/>
     <parameter name="publish-endpoints" default="tcp"/>

     <icebox id="${instance-name}" exe="icebox" activation="always">

       <service name="${instance-name}" entry="IceStormService,35:createIceStorm">

         <dbenv name="${service}"/>

         <adapter name="${service}.TopicManager"
          id="${instance-name}.TopicManager"
          endpoints="${topic-manager-endpoints}">
          <object identity="${instance-name}/TopicManager" type="::IceStorm::TopicManager"/>
        </adapter>

        <adapter name="${service}.Publish"
          id="${instance-name}.Publish"
          endpoints="${publish-endpoints}"/>

          <properties>
           <property name="${service}.InstanceName" value="${instance-name}"/>
           <property name="${service}.Trace.TopicManager" value="2"/>
           <property name="${service}.Trace.Topic" value="2"/>
           <property name="${service}.Trace.Subscriber" value="2"/>
         </properties>

       </service>
     </icebox>
   </server-template>

   <node name="Node1">
    <server-instance template="IceStorm"/>
  </node>

</application>

</icegrid>

and the commands I am executing are:

icegridregistry --Ice.Config=config.registry &
icegridnode --Ice.Config=config.node &
icegridadmin --Ice.Config=config.registry,config.node -e "application add 'application.xml'" &

Any idea what might be going wrong?

    You should update the IceStorm entry point to 3.7 IceStormService,37:createIceStorm instead of IceStormService,35:createIceStorm in your server template.

    If you want to run icegridregistry and icegridnode in background is preferable to use --daemon command line argument instead of &.

    I don't see why you want to run icegridamin in background, this command shouldn't take too long to finish.

    Cheers,
    José

    Hi José,

    Thanks for that! Unfortunately, it doesn't seem to fix the issue :/

    Also, if this was the problem, wouldn't proxies not work too? The weird thing for me is that communication via proxy works fine.

    Best,
    Pavlos

    What is the process that crash? can you provide a stack trace of the crash?

    Sure!

    Can you enable IceGrid.Node.Trace.Activator=3 and IceGrid.Node.Trace.Adapter=3 in icegridnode, it is not clear where the -e 1.0 is coming from

  • ptriantdptriantd Member Pavlos TriantafyllouOrganization: PersonalProject: Robotics SW

    icedb.lock seems to not exist...

    Just some more info about that... When we switched to Ice 3.7, we changed IceGrid.Registry.Data=registry to IceGrid.Registry.LMDB.Path=registry. Should we have done something more?

  • xdmxdm ZeroC Staff La Coruña, SpainAdministrators, ZeroC Staff Jose Gutierrez de la ConchaOrganization: ZeroC, Inc.Project: Ice Developer ZeroC Staff

    Your IceStorm service template is missing LMDB configuration

    <property name="${service}.LMDB.Path" value="${service.data}"/>

    See https://github.com/zeroc-ice/ice/blob/3.7/cpp/config/templates.xml#L42

    Seems an attempt to bind is failing, can you enable network tracing in the service properties

    Can you paste or upload the configuration files used in you last attempt so that we can try with the same configuration.

    Of course!

    I am attaching the application xml, the config files and the bash script I am using (I have added a .txt extension because I couldn't upload them otherwise).

    I tested your configuration files and worked fine in my box, I think it might be failing to bind to one of your interfaces.

    probably the Ice.Admin adapter created by IceBox, can you try adding

     <icebox id="${instance-name}" exe="icebox" activation="always">
           <option>--Ice.Trace.Network=2</option>
           <property name="Ice.Admin.Endpoints" value="tcp -h 127.0.0.1"/>
    ....
    </icebox>

    Thanks José!! It worked like a charm!

    Could you briefly explain what this fix means?

  • xdmxdm ZeroC Staff La Coruña, SpainAdministrators, ZeroC Staff Jose Gutierrez de la ConchaOrganization: ZeroC, Inc.Project: Ice Developer ZeroC Staff

    The default endpoint for Ice.Admin adapter is tcp -h localhost, if your system is properly configured for ipv6 localhost usually expands to 127.0.0.1, ::1 meaning /etc/hosts have something like:

    127.0.0.1       localhost
    # The following lines are desirable for IPv6 capable hosts
    ::1     localhost ip6-localhost ip6-loopback
    

    In this case your lo interface should have both ipv4 and ipv6 addresses

    ip addr show
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
        inet 127.0.0.1/8 scope host lo
           valid_lft forever preferred_lft forever
        inet6 ::1/128 scope host 
           valid_lft forever preferred_lft forever
    

    I assume that your Ubuntu machine has a missconfigured ipv6 for localhost and as result the bind of tcp -h localhost was failing, it will be good to fix the ipv6 configuration and use the default endpoint.

    We have a issue open in github to improve the SocketException to help debugging this issues, see https://github.com/zeroc-ice/ice/issues/389

    Then regarding your configuration a few things that you can cleanup:

    IceGrid.Registry.DynamicRegistration=1 This doesn't seems useful in your case as your servers are not using dynamic registration, you are defining them in the xml descriptor.

    Ice.MessageSizeMax=10000000 You shouldn't need that for the registry configuration as it doesn't send large requests

    IceGrid.Node.CollocateRegistry This is mean to run the registry in the same process than the node, as you are running them as separate process doesn't make sense to set this.

    <dbenv name="${service}"/> This is not required for IceStorm, it doesn't use Freeze anymore.

    Cheers,
    José
