--
I think this problem is only for Oak level observer and not for JCR Listeners?
As there the listener should be unregistered and whole Repository service is
closed and restarted
If yes then yes we should fix such observers to reset there state post
NodeStore restart

bq. Why do observers survive a restart anyway?
Yup thats also puzzling me. Would need to find out why observer survive restart

Marcel Reutegger commented on OAK-3373:
---
bq. what is the above mentioned if used for
It make sure the optimizations done in the if block are correct. Two
DocumentNodeStates from different stores may have the same revision but will
not necessarily be equal.
bq. convert the state which points to a disposed, old store into a state which
points to the new store
I think this is wrong. There is no guarantee the new store is a restarted
incarnation of the currently set store.
Why do observers survive a restart anyway? At least
{{org.apache.jackrabbit.oak.spi.commit.Observer}} are registered with the
{{NodeStore}} and I'd assume they are not automatically carried over.

{quote}bq. convert the state which points to a disposed, old store into a state
which points to the new store
I think this is wrong. There is no guarantee the new store is a restarted
incarnation of the currently set store.{quote}
What other store would it be from?
If this cannot be generalized, then perhaps we need a more explicit
initialization of Observers - so that the restarted store first initializes the
Observers with the then-valid nodeState - and Observers must then live with the
fact that they might have missed a few events (between the old store begin
forcibly crashed and the new store coming back up - as part of OAK-3250)

bq. There is no guarantee the new store is a restarted incarnation of the

what about using the clusterId of the revisions additionally? if that matches
wouldn't it be 'enough guarantee'?
{code}
if (store != mBase.store && mBase.store.isDisposed() &&
mBase.rev.clusterId==rev.clusterId) {
mBase = mBase.clone(); //...
mBase.store = store;

bq. Why do observers survive a restart anyway?
They are removed ({{ObserverTracker.removedService}}) from the old store and
then added ({{ObserverTracker.addingService}}) with the new store again. So
they are properly unregistered/registered from old to new, that part works as
normal, all fine.
But the part where the problem lies is that as soon as the Observers get the
first {{contentChanged}} (which is first happening at register time), they get
a NodeState with the new store - and that one they want to do a
{{compareAgainstBaseState}} with the last NodeState they have - which was from
the old store. So the problem is really just the 'switch over' when they
receive the first 'new' NodeState.

bq. They are removed (ObserverTracker.removedService) from the old store and
then added (ObserverTracker.addingService) with the new store again.
In my view, this is what needs to be changed. Let's say the node store is
restarted because of a hypothetical re-configuration and now points to a
different DocumentStore. We don't support this right now, but we could in the
future. In this case, the state of the restarted node store my be completely
unrelated to the state of the node store before. I think an Observer should not
be re-registered as is with the new node store, but rather be reset with a new
base root state from the new node store.

Michael Dürig commented on OAK-3373:
bq. and then added (ObserverTracker.addingService) with the new store again.
This sounds scary. E.g. {{BackgroundObserver}} might have more "old" node state
in its queue.
On a separate note, I don't think we ever considered the use case of restarting
the node store. Other components might also not be prepared for this (i.e.
holding on to "old" node states). Those in the observers might just be the
lowest hanging fruit.

Stefan Egli commented on OAK-3373:
--
In {{DocumentNodeState.compareAgainstBaseState}} there is already a check for
[{{if (store ==
mBase.store)}}|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/document/DocumentNodeState.java#L335]
- which will be {{false}} in case of a store restart.
One way to solve the failing-observers-after-restart-problem would be to do
something along the following lines (right before the above {{if}}):
{code}
if (store != mBase.store && mBase.store.isDisposed()) {
mBase = mBase.clone(); //...
mBase.store = store;
}
{code}
so basically convert the state which points to a disposed, old store into a
state which points to the new store.
[~chetanm], [~mreutegg], [~reschke], wdyt? .. and what is the above mentioned
{{if}} used for?
