This commit improves support for use of Spring Session with Hazelcast's client-server topology by ensuring SessionUpdateEntryProcessor is easier to serialize to the cluster. This is done by refactoring SessionUpdateEntryProcessor from static inner class of HazelcastSessionRepository to a dedicated class, therefore minimizing the dependencies to other Spring Session components.
Closes gh-1101
Currently, Session#getAttributeNames implementations, by delegating to MapSession, all return a session attribute map's key set. This causes ConcurrentModificationException when an attempt to modify session attributes is made while iterating over the returned attribute names.
Closes gh-1120
Previously, invoking HttpServletRequest#changeSessionId on session backed by HazelcastSessionRepository generated generated invalid session destroyed and session created events. This was due to use of IMap#remove and IMap#set when handling the change session id.
This commit improves change session id handling to prevent publishing invalid events by using IMap#delete instead of IMap#remove and keeping track of originally assigned session id.
Closes gh-1077
This commit ensures that Redis Testcontainers used for integration testing are managed by Spring to ensure proper ordering on shutdown.
Previously, Redis Testcontainer was closed before LettuceConnectionFactory which caused pending commands to hang and added a lot of wait to project build.
Closes gh-1086
This commit improves HazelcastSessionRepository.SessionUpdateEntryProcessor to avoid NPE in scenario where save operation was invoked for session that was already deleted.
See gh-1076
This commit optimizes session attribute saving by ensuring batch updates are used whenever possible. To make this possible, delta now tracks operations for each attribute change in order to be able to deduce SQL operation.
Additionally, if there is only a single attribute change, regular update is executed rather than batch operation.
Closes gh-1051
