It looks to me as if the jiras just say you'd like this feature without explaining how it would work.
Even though we don't yet have an isolation environment in geronimo, I'd like to know how this would work if we did. Lets say you have an EBA with bundles A, B, and C, B imports packages from A and services from A and C, C imports packages and services from A, B, and C. Now you want to replace B with B' . What are the state changes for A, B, B', and C in what order? Can B' alter the import requirements for the EBA? If the EBA defines an isolation environment, how does the deployer know that it should be putting B' inside the EBA rather than outside the EBA? If we can make this work, great, I want to be sure we won't have to rip it out again or completely reimplement it when we have subsystems. thanks! david jencks On Mar 15, 2011, at 8:06 PM, han hongfang wrote: > Hi all, > > I would like to hear the comments for the solution proposal for updating a > bundle within an EBA, and the related JIRAs are: > > https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-718 Update a bundle > within an EBA > https://issues.apache.org/jira/browse/GERONIMO-5861 Update a bundle within an > EBA > > The point of the JIRA is to ONLY re-deploy the updated bundle in EBA instead > of re-assembling and re-deploying the whole EBA to save the time in the case > that the EBA is huge. > > The rough proposal is: > Step 1. update a specified bundle using osgi:update > Step 2. osgi:refresh the other bundles in the EBA to refresh the links to the > updated bundle > > This means that the updated bundle will be only in the cache, and in the > following cases the updated bundle will be lost, and the original bundle > included in EBA archive file comes back. > 1.
