Affects: 5.3.10

I was planning to build a minimal reproducible project for this https://github.com/spring-projects/spring-framework/issues/28968, but now I have something even stranger, it might also be related to "spring-tx" but I still feel like it should be raised here originally. Because I (almost) never use spring-tx directly, so.. Anyway, let me know and I will move the issue to a proper project, if necessary.

So, we have a very small integration test: https://github.com/62mkv/spring-cockroach-transaction-retry/tree/duplicate-commit

This code demonstrates really weird (to me) behaviour: it tries to execute "COMMIT" twice, on a same transaction, which brings it first to "no transaction exists" exception and then (it seems) also tries to ROLLBACK, which also causes another exception again, this time from Spring infra.

Here's the logs I get:

the original issue text:

I've already commented under commit diff, although I am not sure if it's visible to anyone, so I decided to post an issue too: https://github.com/spring-projects/spring-framework/commit/b5e5e3307838359b42c7f4b1ed592b03b249eb4f#r81307010

In the current main version, that would be question about https://github.com/spring-projects/spring-framework/blob/b595dc1dfad9db534ca7b9e8f46bb9926b88ab5a/spring-tx/src/main/java/org/springframework/transaction/reactive/AbstractReactiveTransactionManager.java#L448

    })).then(Mono.empty().onErrorResume(ex -> {

I both can not imagine how that onErrorResume could be activated for a MonoEmpty publisher; also I have not been able to trigger any breakpoint inside this lambda, even though I can confirm that code visits both assembly phase parts and lambdas before and after this code.

Thanks for checking this out!

Some context: I am fighting a situation where, faced with an exception while COMMIT, the code (instead of retrying transaction, as we would want to, per https://www.cockroachlabs.com/docs/v22.1/transactions.html#client-side-intervention) tries to issue yet another COMMIT, which of course fails and now it's not a retryable exception even.

Comment From: mp911de

There are a couple of things that come together:

  1. The commit exception handling is wrong and Mono.empty() does nothing (as pointed out). Fixing that issue reveals a couple other problems:
  2. The commit exception translation in R2dbcTransactionManager translates the commit failure into a DAO exception instead of a TransactionException. That leads to doRollbackOnCommitException which is unconditional. PlatformTransactionManager has a flag isRollbackOnCommitFailure that defaults to false.
  3. TransactionOperator's exception handling always calls rollbackOnException, rollbackOnException should happen only for exceptions during the actual action, not on commit errors. TransactionAspectSupport suffers from the same issue.
  4. The Postgres driver signals the error early on without consuming the final response frame so it attempts a transaction cleanup. I filed https://github.com/pgjdbc/r2dbc-postgresql/issues/541

The most difficult part was to simplify the reproducer. I'm going to submit a pull request to fix these issues but it can take a while because I'm currently busy with other tasks.

    • The erroneous then(Mono.empty().onErrorResume(…)) needs to be a onErrorResume(…) to properly catch and handle errors if the underlying COMMIT fails. I hadn't had the bandwidth to come up with a proper test, in combination with TransactionalOperator the commit should not lead to another top-level-rollback but rather cleanup the transaction following the ErrorPredicates cleanup mechanisms (after-completion or doRollbackOnCommitException).

    I'll try to come up with a unit test that can reproduce this, and apply @mp911de 's patch (thanks Mark)

    I am closing this issue in favor of the PR #30096.
