Adding persistable contributions to Extensionregistry [message #496800]

HI,

I need to add persistable contributions to the ExtensionRegistry. I digged in a little and found the method addContribution(..) in Extensionregistry. But to enable persistence it expects a mastertoken as the last parameter. Except reflection I could not find a way to get the master token.

Is there a way around for such a problem.

Thanks,

no. If you want to add a persistant entry to the registry you must use the master token. That means either you have to be responsible for creating the registry yourself (in an OSGi or RCP app, somehow using low level hooks) or you use reflection to do it (not recommended) as you would have to figure out when your contributions disappeared (from a -clean, for example) and re-add them as the extension registry is re-building its cache.

Why not create and install a small plugin with your contributions using OSGi? They would show up and stay around more reliably (with the down side that you have to create them on disk to load them).

Thanks Paul for active response,

Actually we have a huge framework(in fact twice as big as eclipse in code size) that we are integrating with Equinox. Now we had plugin architecture too but they are custom plugins not standard OSGI format. Some time back we integrated extension registry in the framework, so we had created our ExtensionRegistry object and hence had the reference for the master-token. But now we are integrating the framework with eclipse so instead of creating our own ExtensionRegistry object we now are adding the contributions to the equinox's registry, but as we don't have the master token, its not persistable.

This is creating a huge startup performance issue for us.
Is there a way around this problem. I google around and found that others are facing similar problem too.

Hi Paul,

We have worked with a solution for this problem and would like to contribute it to the equinox code base. Is is possible? Can you please tell the process.

Hi Suraj,
The good starting point would be to open an enahncement request against
RT/Equinox/Components:

https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Equinox

and attach patch to it.

Sincerely,
Oleg Besedin
