Summary

When the callback passed to withTransaction throws, invalidate the transaction context immediately before awaiting transaction.rollback(). Previously, invalidated was only raised in the outer finally block, allowing pending or concurrent statements to pass closed checks and reach the database after ROLLBACK had completed.

Testing performed

Ran unit tests in packages/2-sql-family/5-runtime/test/with-transaction.failures.test.ts verifying that concurrent statements executed while ROLLBACK is pending are immediately rejected with RUNTIME.TRANSACTION_CLOSED.
Ran unit tests in packages/2-sql-family/5-runtime/test/sql-runtime.test.ts (all 37 tests passing cleanly).

Summary by CodeRabbit

Bug Fixes
- Transactions now reject further statements as soon as the transaction callback fails, including while rollback is still pending.
- The transaction continues to report the original callback error after rollback handling completes.

…ack error When the callback passed to withTransaction throws, the transaction context must be invalidated immediately before initiating transaction.rollback(). Previously, invalidated was set only in the outer finally block after ROLLBACK completed, which allowed concurrent statements still executing or issued while rollback was pending to pass closed checks and reach the connection after ROLLBACK had completed.

Walkthrough

When a transaction callback throws, withTransaction now invalidates the transaction context before rollback begins. A new test checks that a statement issued while rollback is pending rejects with RUNTIME.TRANSACTION_CLOSED, while withTransaction rejects with the callback error.

Changes: Failed transaction handling

Layer / File(s)	Summary
Invalidate the context before rollback `packages/2-sql-family/5-runtime/src/sql-runtime.ts`, `packages/2-sql-family/5-runtime/test/with-transaction.failures.test.ts`	The callback error path invalidates the transaction context before rollback begins. The test checks that a statement issued while rollback is pending rejects with `RUNTIME.TRANSACTION_CLOSED` and that `withTransaction` rejects with the callback error.

Merge Risk: High · up to 7c855

This change rejects statements issued after a transaction callback throws, but statements already admitted can still run after the rollback, which is the data-integrity case the linked issue describes. The new test can also pass without catching the regression when setup is slow. Fix the admitted-statement gap and make the test deterministic before merging.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base changes two files. sql-runtime.ts adds one line that sets invalidated = true in the withTransaction catch block. with-transaction.failures.test.ts adds one test that exercises that behavior. Both changes fall within issue #30878 and the stated PR objective. The change adds no unrelated refactoring, documentation, or API change. The summary reports no alterations to exported or public declarations.

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Full details: Linked Issues check

Explanation

Issue #30878 requires two behaviors in the withTransaction error path: (1) statements issued after the callback throws are refused with RUNTIME.TRANSACTION_CLOSED, and (2) no statement of the transaction reaches the database after its ROLLBACK. The change at packages/2-sql-family/5-runtime/src/sql-runtime.ts line ~1925 adds invalidated = true; in the catch block before await transaction.rollback(). The existing finally block still sets the flag after rollback. This closes the window for statements issued while ROLLBACK is pending, which covers the reported Promise.all and delayed-statement cases. The new test in with-transaction.failures.test.ts issues a statement 10 ms after the throw while rollback is held until 50 ms and expects RUNTIME.TRANSACTION_CLOSED. Before this change, the flag was still false at that point, so the test exercises the reported bug. Requirement (2) also covers a statement that passed the closed check before the throw and was still in the middleware or encoding pipeline when ROLLBACK was sent (issue #30878, and PR objectives). The diff does not show where the closed check runs relative to middleware and encoding, or whether the check repeats immediately before the driver send. The truncated file read did not show the closed check. Whether that in-pipeline case is covered is therefore not established. The author's test runs are reported in the PR description but were not reproduced here.

Resolution

Confirm where the invalidated check runs in the statement execution path of sql-runtime.ts, relative to middleware and parameter encoding. Confirm that a statement which passed the entry check before the callback threw is rejected before it reaches the driver. If the check runs only at entry, add a check immediately before the driver send, plus a test where a statement is in middleware or encoding when the callback throws and ROLLBACK is pending. Provide the test run output that shows the new test fails without the fix and passes with it.

Drain admitted statements before rollback.

invalidated blocks new calls, but an execute that passed the guard can still wait in beforeEncode. rollback() stops new children and sends ROLLBACK without waiting for that statement. The statement can then reach the PostgreSQL driver after ROLLBACK and execute outside the transaction.

Ensure rollback waits for admitted statements, or cancels them and waits for cancellation, before sending ROLLBACK and releasing the connection.

Release rollback only after asserting statement rejection.

withTransaction awaits connection and transaction setup before invoking the callback. The test registers the 50 ms release timer before it knows that the callback has started. The statement waits 10 ms only after the callback starts. If setup takes more than 40 ms, rollback can be released before tx.execute(...) runs. The merge-base implementation then invalidates the context in finally, so this test can pass without detecting the regression.

Wait for rollback to start, assert the statement rejection while rollback remains held, then release rollback and await run.
