Updates are not installed properly? [message #841510]

Hi, I use p2 in the standard way in my rcp application (based on eclipse 3.7.2) to add update capabilities to my rcp application. I succeded to update some of my plugins via a remote update site. After the update my app does not work properly: I have problems with the ui, because a StackOverflowException is thrown (see uploaded file). Checking using the console shows, that the newly installed bundles are set to lazy with a lower bundle id, while the older one have the status installed and a higher id. I have been thinking, that p2 uninstalls older versions and installs newer versions. Have I anything to do, that older bundles are replaced by newer ones (I mean, that at startup time the newer bundles are used while older ones are ignored)?

Thank you!

Hi,

This is likely because the feature that included the orginal bundles has not been uninstalled. If you use the p2 UI that should just work, if you are using the p2 API you have to be sure to uninstall the previous feature and install the new one.

HTH,

Hi Pascal,

I use p2 ui "out of the box". Inspecting the feature directory, I find just the new feature. When I delete the old plugins in the plugin folder, the app starts properly. Is it possible, that there exists a "registry" that is not updated cleanly?

Hi F FA,

unfortunately I can not access the website of vogella (may be it is down?). As I see it, you don't have to add those commands. It seems, that you have set up p2 correctly as the menues are active and work correctly.

I do it in the following way:

Initially I set the version numbers in my plugins, features and product to (e.g. 1.0.0.201204121110 (major 1, minor 0, service 0, qualifier date and time (yyyymmddhhnn).

Each time I prepare an update for changed plugins, I update the qualifier to an actual timestamp (as described above) and do the same in the features that contain the plugins.

I add the the updated features to the site.xml and build the site.xml. Then I update the update site using rsync.

After that the next time I start my app, p2 messages that there is an update available (I do not automatic updates).

I hope that helps you.

Christian
