Description
This PR addresses issue #4262 by adding support for the previous_transaction_id in DatastoreTransactionManager. This allows for better handling of sequential transactions and improves idempotency when interacting with Google Cloud Datastore.
Key Changes:
Dynamic Transaction Options: Updated doBegin to utilize TransactionOptions.Builder, allowing the inclusion of a previousTransactionId if present in the Tx object.
Nullability Compliance: Added @nonnull and @nullable annotations to override methods to satisfy the project's @NonNullApi constraints and resolve IDE warnings.
Code Cleanup:
Removed redundant null checks in doCommit and doRollback to resolve "always true" logic warnings.
Optimized doCleanupAfterCompletion using Java's pattern matching for instanceof.
Unit Testing: Added a new test class DatastoreTransactionManagerTests to verify that the previousTransactionId is correctly propagated to the Datastore client.
Verification Results:
Linter/IDE: 0 problems found in IntelliJ (all nullability and "unused method" warnings resolved).
Tests: testBeginWithPreviousTransactionId passed successfully.
