Hi,
I'm proposing we add a new method to the GeoServerLifecycleHandler
interface:
/**
* Called when a reload is starting, see onReload for a notification that
the reload ended
*/
void beforeReload();
The method will allow implementors to do special actions during the reload
period,
and the implementation in GeoServerImpl will make sure once beforeReload()
is
called, a call to onReload() is guaranteed().
Use cases for this method:
* interact with a custom servlet filter that will block all incoming ogc
requests
during the reload (they will likely fail anyways)
* notify load balancers and put the node temporary out of the pool
The change will affect all implementations of GeoServerLifecycleHandler and
break them, of course all
the ones in GeoServer will be fixed. Given this, no attempt to backport the
change will be made
(GeoServerLifecycleHandler is after all a pluggable interface, everybody
can implement
it and use it custom extensions).
Cheers
Andrea
