Felix Meschberger updated SLING-2791:
-------------------------------------
Attachment: SLING-2791.patch
Proposed patch.
Adds new -n command line option to prevent installation of a shutdown hook.
Adds support for a new system/configuration property sling.shutdown.hook: If
set to true or not set at all, the hook is installed, otherwise the hook is not
installed.
> No way for graceful server shutdown
> -----------------------------------

> Key: SLING-2791
> URL: https://issues.apache.org/jira/browse/SLING-2791
> Project: Sling
> Issue Type: Bug
> Components: Launchpad
> Affects Versions: Launchpad Base 2.5.0
> Reporter: Philipp Marx
> Assignee: Felix Meschberger
> Priority: Minor
> Attachments: SLING-2791.patch
>
>
> The main class of the launchpad-base will register a shutdown hook on the JVM
> to tear down the felix framework properly (Framework#shutdown). There are
> certain situation where a client wants to have a different behaviour, i.e. to
> implement a graceful server shutdown.
> In Felix itself you can set the "felix.shutdown.hook=false" to prevent Felix
> from registering its own shutdown hook. It would be great if Sling would
> provide the same functionality.
> I have already a patch in place which will search for the same property as
> Felix and in case this is set to true will not create its own shutdown hook
> but will rely on the client to properly shutdown the framework. I know there
> are more actions which Sling is doing upon JVM shutdown but since there is
> also a listener on the Framework shutdown itself these actions will still be
> performed.
