To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.
Closes gh-27098
This commit improves the Javadoc regarding transactional semantics for
@TransactionalEventListener methods invoked in the AFTER_COMMIT,
AFTER_ROLLBACK, or AFTER_COMPLETION phase. Specifically, the
documentation now points out that interactions with the underlying
transactional resource will not be committed in those phases.
Closes gh-26974
Prior to this commit, if the DataSource in the
DataSourceFromTransactionManager was wrapped in a proxy implementing
InfrastructureProxy, SqlScriptsTestExecutionListener would throw an
exception stating that the DataSource in the ApplicationContext and the
DataSource in the DataSourceFromTransactionManager were not the same.
This commit unwraps both data sources and compares the underlying
target instances to check for equality.
In addition, this commit makes the unwrapResourceIfNecessary() method in
TransactionSynchronizationUtils public.
Closes gh-26422
This commit makes TransactionInterceptor and TransactionAspectSupport
Coroutines aware, adapting Reactive transaction support to Coroutines.
Suspending functions returning a Flow are handled like Flux, for other
return types, they are handled like Mono.
Closes gh-23575
Includes forPayload methods and common adapter classes for programmatic usage.
Aligns default order values for event handling delegates to LOWEST_PRECEDENCE.
Closes gh-24163
Issues gh-25038 and gh-25618 collectively introduced a regression for
thread-scoped and transaction-scoped beans.
For example, given a thread-scoped bean X that depends on another
thread-scoped bean Y, if the names of the beans (when used as map keys)
end up in the same bucket within a ConcurrentHashMap AND an attempt is
made to retrieve bean X from the ApplicationContext prior to retrieving
bean Y, then the use of Map::computeIfAbsent in SimpleThreadScope
results in recursive access to the same internal bucket in the map.
On Java 8, that scenario simply hangs. On Java 9 and higher,
ConcurrentHashMap throws an IllegalStateException pointing out that a
"Recursive update" was attempted.
In light of these findings, we are reverting the changes made to
SimpleThreadScope and SimpleTransactionScope in commits 50a4fdac6e and
148dc95eb1.
Closes gh-25801
PR gh-25038 introduced regressions in SimpleThreadScope and
SimpleTransactionScope in Spring Framework 5.2.7. Specifically, if a
thread-scoped or transaction-scoped bean has a dependency on another
thread-scoped or transaction-scoped bean, respectively, a
ConcurrentModificationException will be thrown on Java 11 or higher.
The reason is that Java 11 introduced a check for concurrent
modification in java.util.HashMap's computeIfAbsent() implementation,
and such a modification can occur when a thread-scoped bean is being
created in order to satisfy a dependency of another thread-scoped bean
that is currently being created.
This commit fixes these regressions by switching from HashMap to
ConcurrentHashMap for the instance maps in SimpleThreadScope and
SimpleTransactionScope.
Closes gh-25618
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.
- The compiler is configured to retain compatibility with Kotlin 1.3.
- Explicit API mode is not yet enabled but could be in the future.
- A workaround for Gradle build is required for now, see
https://youtrack.jetbrains.com/issue/KT-39610 for more details.
- Some exceptions thrown by Kotlin have changed to NullPointerException,
see https://youtrack.jetbrains.com/issue/KT-22275 for more details.
