> Components: Launchpad
> Affects Versions: Launchpad Base 2.5.0
> Reporter: Chetan Mehrotra
> Priority: Minor
> Attachments: SLING-3386.patch

>
> By default OSGi framework does not define the order in which bundles would be
> started in a given start level. The only way is to use to use start level.
> However in case of bundle like Logging its desriable that Log bundle is the
> first bundle to start in the system such that it does not miss any log
> message. The problem is described in more details at SLING-3340.
> As Sling uses Felix framework by default it is possible to control the start
> order by controlling the order in which bundles are installed on the
> framework. As per current Felix Framework implementation [1] bundle within
> same start level are started in the order of bundleId.
> The way patch works is
> 1. Bundle which start at start level 1 can define a header
> 'X-Sling-Start-Order' to provide a start order hint. Lower the level then
> earlier the bundle would be started
> 2. BootstrapInstaller would sort the files obtained from directly listing
> based on this header.
> 3. Sorted list would be used to install the bundles
> I understand that this is a very much implementation specific fix and might
> not work if Felix changes the internal logic. But then the feature is meant
> to be used in best effort basis!!.
