Use Case

As a MongoDB Node.js driver user, I want the transaction state machine in /src/transactions.ts to correctly categorize TRANSACTION_ABORTED, so that the logic aligns with expected transactional behavior.

User Experience

The incorrect categorization could lead to unexpected behavior when checking if a transaction is committed. This may cause misinterpretations in application logic relying on isCommitted().

• Impact: All users relying on transaction state checks.
• Severity: Medium, as it could lead to incorrect business logic decisions.

Dependencies

Check if other drivers (Python, Java, etc.) have the same issue for consistency.

Risks/Unknowns

• Could changing this behavior break existing applications?
• Do any tests or internal logic depend on TRANSACTION_ABORTED being in committed states?

Acceptance Criteria

• TRANSACTION_ABORTED should not be included in COMMITTED_STATES in /src/transactions.ts.
• isCommitted() should return false for aborted transactions.
• Ensure no unintended breakages in transaction handling.

Testing Requirements

• Unit tests to verify state transitions.
• Ensure isCommitted() returns expected results.

Documentation Requirements

• Update API documentation to clarify expected behavior if needed.

Follow Up Requirements

• Confirm behavior with database team.
• Check if changes need to be reflected across other MongoDB drivers.
