This commit introduces a change in reactive transaction semantics for
cancel signals. Canceling a subscription now rolls back a reactive transaction
to achieve a deterministic transaction outcome.
Previously, cancel signals committed a transaction which could
cause partially committed transactions depending on when the cancel happened.
Prior to this commit, the TransactionAttributeSourceClassFilter
filtered out PlatformTransactionManager but not
ReactiveTransactionManager implementations.
TransactionAttributeSourceClassFilter now filters out any
TransactionManager implementation, covering both imperative and
reactive transaction managers.
TransactionAttribute now exposes a labels attribute that associates a
descriptive array of labels with a transaction.
Labels may be of a pure descriptive nature or may get evaluated by
transaction managers to associate technology-specific behavior
with the actual transaction.
This commit renames the Runnable variant to executeWithoutResult
and uses a Consumer<TransactionStatus> parameter for better
consistency with TransactionCallbackWithoutResult.
Closes gh-23724
TransactionOperator.as(Mono) now no longer short-cuts via a Flux.next() but provides an implementation via Mono.usingWhen(…).
The short-cut previously issued a cancellation signal to the transactional Mono causing the transaction cleanup to happen without a handle for synchronization.
Using Mono.usingWhen(…) initiates transaction cleanup when the Mono completes eliminating the need for cancellation of the transactional Publisher.
This change does not fully fix gh-23304 but it softens its impact because TransactionalOperator.transactional(Mono) avoids cancellation.
This commit adds Coroutines extensions for
TransactionalOperator.transactional that accept suspending lambda or
Kotlin Flow parameters.
@Transactional on suspending functions is not supported yet, gh-23575
has been created for that purpose.
Closes gh-22915
This commit fixes the behaviour of not triggering a transactional event
listener if no transaction is active. Previously, a transaction boundary
was all that was necessary to trigger the listener regardless of the fact
there was an active transaction.
This commit now prevents `Propagation.NOT_SUPPORTED` and
`Propagation.SUPPORTS` without an active transaction to trigger the
listener.
Closes gh-23276
