Before reporting an issue

Area

infinispan

Describe the bug

When an entity is created in a transaction and deleted in the same transaction, the entity is marked and transient, and no operation is performed in the Infinispan cache.

However, if the entity is "deleted" twice (or more), the second time resets the transient status; a remove operation is executed in the Infinispan cache. Although not wrong, it is a waste since there is nothing to remove.

It happens in the method below:

The method removeAuthenticationSessionByTabId() deletes the entity on the last authentication session, but the AuthenticationSessionManager invokes the removal again.

Version

main

Regression

• The issue is a regression

Expected behavior

No remove operation is expected in the Infinispan cache.

Actual behavior

Keycloak tries to remove an inexisting session.

How to Reproduce?

Remove an entity twice and count the number of operations executed in the Infinispan cache. It should be zero. I'll add a test for it.

Anything else?

It is the possible cause of the random failures in the cross-site test ConcurrentModificationTest.
