Subject [jira] [Commented] (SLING-9172) Allow Sling Installer to install and handle multiple versions of bundles instead of updating
Date Thu, 05 Mar 2020 10:58:00 GMT

    [ https://issues.apache.org/jira/browse/SLING-9172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17052006#comment-17052006

Konrad Windszus commented on SLING-9172:
----------------------------------------

My concern is that this feature may break stuff once merged and activated. Therefore we should
also fix the downstream consumers before merging this!

> Sling Installer currently always updates bundles when different versions of bundles get
installed. Since Apache Felix does support multiple versions of bundles to exist in parallel
it should be possible to change the behavior with via property to install and uninstall multiple
versions in parallel instead of updating them.
> To achieve this two changes are required:
> a) DefaultTransformer should change the EntityID of bundles to include the version to
make sure the state handling of Installer handles each version as own entity
> b) BundleTaskCreator must be adjusted to create install task over update task as the
detection currently checks for the existence of BSN
