Julian Reschke updated OAK-4089:
--------------------------------
Fix Version/s: 1.6
> The standby store shouldn't start the observation subsystem
> -----------------------------------------------------------
>
> Key: OAK-4089
> URL: https://issues.apache.org/jira/browse/OAK-4089
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: tarmk-standby
> Reporter: Francesco Mari
> Assignee: Francesco Mari
> Fix For: 1.6, 1.5.0
>
>
> The current implementation of {{SegmentNodeStore}} unconditionally
> instantiates a {{ChangeDispatcher}} referencing the root node of the
> repository at the time of instantiation.
> When this occurs in the context of the standby store, the
> {{ChangeDispatcher}} is never notified for changes in the repository content,
> and the initial repository root is permanently referenced by the
> {{ChangeDispatcher}}. This prevents many segments from being correctly
> cleaned up from the standby store.
> It would be more appropriate not to instantiate the observation subsystem at
> all in the context of the standby store, thus preventing spurious references
> to {{SegmentId}} instances to float in memory.
