Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.
This change introduces the `featurePermissionDelegationV1_1` amendment, which is designed to supersede both `featurePermissionDelegation` and `fixDelegateV1_1 amendments, which should be considered deprecated. The `checkPermission` function will now return `terNO_DELEGATE_PERMISSION` when a delegate transaction lacks the necessary permissions.
- Still required for the transaction to succeed (except inside a Batch,
because the batch signers take care of that).
- Started adding tests for Loan-related RPC and low-level math checks.
Currently only implemented "sign" on a LoanSet to verify it can be
done.
- Addresses FIND-001 from audit
- LoanSet::preflight will require Counterparty to be set (it's normally
optional) for an inner batch transaction, because the checks are done
before the LoanBroker object can be accessed.
- Adjust LoanSet::calculateBaseFee to not charge extra if an inner
transaction.
- Adds a Loan-specific test to Batch_test.
The tests that ensure `tfInnerBatchTxn` won't block delegated transactions silently fail in `Delegate_test.cpp`. This change removes these cases from that file and adds them to `Batch_test.cpp` instead where they do not silently fail, because there the batch delegate results are explicitly checked. Moving them to that file further avoids refactoring many helper functions.
- Specification: [XRPLF/XRPL-Standards 56](https://github.com/XRPLF/XRPL-Standards/blob/master/XLS-0056d-batch/README.md)
- Amendment: `Batch`
- Implements execution of multiple transactions within a single batch transaction with four execution modes: `tfAllOrNothing`, `tfOnlyOne`, `tfUntilFailure`, and `tfIndependent`.
- Enables atomic multi-party transactions where multiple accounts can participate in a single batch, with up to 8 inner transactions and 8 batch signers per batch transaction.
- Inner transactions use `tfInnerBatchTxn` flag with zero fees, no signature, and empty signing public key.
- Inner transactions are applied after the outer batch succeeds via the `applyBatchTransactions` function in apply.cpp.
- Network layer prevents relay of transactions with `tfInnerBatchTxn` flag - each peer applies inner transactions locally from the batch.
- Batch transactions are excluded from AccountDelegate permissions but inner transactions retain full delegation support.
- Metadata includes `ParentBatchID` linking inner transactions to their containing batch for traceability and auditing.
- Extended STTx with batch-specific signature verification methods and added protocol structures (`sfRawTransactions`, `sfBatchSigners`).
