Re: [equinox-dev] Question on Profiles / p2 and standalone Osgi

Hi Pascal - One more question. Since I am running a server side application, the execution environment is setup as the standard Equinox OSGI frameworkand not as an Eclipse runtime.  I believe this is why the bundles.info does not get updated. My update site has "features" defined (since I cannot define a product for an OSGI runtime environment) and I can install these features and the plugins are downloaded and the profile is updated as I would expect.  However, the bundles.info is never updated.  After looking at the p2 code it looks like this is only triggered if you are running as an eclipse product and it will never get triggered if you are running in a standard OSGI environment.   Is this expected?

The result of the installation of an IU that contains a bundle should result in the bundle to be listed in the bundles.info in the configuration/org.eclipse.equinox.simpleconfigurator/bundles.info.
To cause the system to "re-consider" this list of bundles, you need to grab the Configurator service (provided by the simpleconfigurator bundle) and call applyConfiguration(). This is how the apply changes dialog is implemented.

Re: [equinox-dev] Question on Profiles / p2 and standalone Osgi




Hi Pascal - I am currently running with the following  VM arguments:

 -Declipse.p2.data.area=C:\p2agent\p2 -Declipse.p2.profile="">

I have written a simple debug plugin that pulls the current "SELF" IProfile and it comes back ExampleProfile.  I have then pulled the IU(s) and they all come back from the profile query.  So it seems like the p2 framework is installed correctly.  Once this is done is there a best practices to reconcile the currently running bundles with the profile IUs - similar to an apply changes? or is it better to iterate through the IUs and install the OSGI bundles directly ?

    Hi,

    The profile is not here to instruct p2 what should be installed in your system. Instead you need to think of it as the record of what has been installed.
    I think that the issue you are encountering is a tooling one where when you are starting an application from within Eclipse, no corresponding profile is created and as such any subsequent p2 operation can be problematic (
    https://bugs.eclipse.org/bugs/show_bug.cgi?id=250126).
    There is currently two work around:
    1) You create a profile for your installation using the admin ui. When you start your application from within the IDE you set the vm arg eclipse.p2.data.area to point at the p2 folder that contains the profile you are running (e.g. -Declipse.p2.data.area=/Users/Pascal/Downloads/eclipse/p2/). You may also want to specify the ID of your profile by setting eclipse.p2.profile as a vm arg (e.g. eclipse.p2.profile=""> 2) You write a bundle that looks around in the running system, generates metadata representing it, and fake up an installation into a profile (you can find most of the code for generation in the publisher bundle). This bundle would be running in the application started. This is really a HACK and should not be used in real systems. I'm giving you this approach as a way for you to progress, but using this in a real product would result in not guaranteeing unicity of metadata, would not allow you to manage all the external files, and finally would have a cost on startup to update the system.

    HTH

[equinox-dev] Question on Profiles / p2 and standalone Osgi




    Hello - I am trying to use profiles with a standalone osgi  
    application. I have set the osgi app to use a specific p2 data area  
    and with a profile I defined using the admin GUI. The profile  
    references a shared bundle location. When I start the osgi application  
    from eclipse it loads the p2 bundles i have defined in my target. I  
    can determine that the app's profile is set to the one I defined and  
    that the profile has the correct list of IUs. What I cannot figure out  
    is how to get the p2 framework to reconcile what is currently  
    installed at startup with what the profile says should be installed.  
    Is it possible to get p2 to update the installed plugins based on a  
    profile passed in at startup?

    Chase
