31651: Fixed up concurrency tests: target concurrent aspect adds in addition to numeric property increments
31652: Ensure DB-based concurrency problems are propagated when updating alf_node (not just optimistic lock detections)
31823: TransactionalCache provides REPEATABLE READ
- Values found in shared cache are placed into transactional cache
- Previously, values could keep changing until first write (READ COMMITTED)
but now the first read sets the value until it is changed by the current
transaction
31825: Minor comment about node version rollover after version=32767
31826: Immutable node caches: properties, aspects and parent assocs are immutable
- cache entries are only put but never updated
- zero cluster overhead for these 3 caches
- Stale nodeCache detection when reading properties, aspects or parent assocs
- Added tests to introspect on the caches directly to validate behaviour
- Ensure that each node gets a single version increment per transaction
31854: Cater for cm:auditable changes during touchNode()
