Chetan Mehrotra resolved SLING-3386. ------------------------------------ Resolution: Won't Fix The original issue would now be addressed via SLING-3388 > Enable support starting bundle in custom oreder at start level 1 > ---------------------------------------------------------------- > > Key: SLING-3386 > URL: https://issues.apache.org/jira/browse/SLING-3386 > Project: Sling > Issue Type: Improvement > 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!!. > [1] > https://github.com/apache/felix/blob/trunk/framework/src/main/java/org/apache/felix/framework/Felix.java#L4873 -- This message was sent by Atlassian JIRA (v6.1.5#6160)
