- Refactor Number internals away from int64 to uint64 & a sign flag
- ctors and accessors use `rep`. Very few things expose
`internalrep`.
- An exception is "unchecked" and the new "normalized", which explicitly
take an internalrep. But with those special control flags, it's easier
to distinguish and control when they are used.
- For now, skip the larger mantissas in AMM transactions and tests
- Remove trailing zeros from scientific notation Number strings
- Update tests. This has the happy side effect of making some of the string
representations _more_ consistent between the small and large
mantissa ranges.
- Add semi-automatic rounding of STNumbers based on Asset types
- Create a new SField metadata enum, sMD_NeedsAsset, which indicates
the field should be associated with an Asset so it can be rounded.
- Add a new STTakesAsset intermediate class to handle the Asset
association to a derived ST class. Currently only used in STNumber,
but could be used by other types in the future.
- Add "associateAsset" which takes an SLE and an Asset, finds the
sMD_NeedsAsset fields, and associates the Asset to them. In the case
of STNumber, that both stores the Asset, and rounds the value
immediately.
- Transactors only need to add a call to associateAsset _after_ all of
the STNumbers have been set. Unfortunately, the inner workings of
STObject do not do the association correctly with uninitialized
fields.
- When serializing an STNumber that has an Asset, round it before
serializing.
- Add an override of roundToAsset, which rounds a Number value in place
to an Asset, but without any additional scale.
- Update and fix a bunch of Loan-related tests to accommodate the
expanded Number class.

This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
- Spec: XLS-66
- Introduces amendment "LendingProtocol", but leaves it UNSUPPORTED to
allow for standalone testing, future development work, and potential
bug fixes.
- AccountInfo RPC will indicate the type of pseudo-account when
appropriate.
- Refactors and improves several existing classes and functional areas,
including Number, STAmount, STObject, json_value, Asset, directory
handling, View helper functions, and unit test helpers.
This change fixes JSON parsing of negative `int` input in `STNumber` and `STAmount`. The conversion of JSON to `STNumber` or `STAmount` may trigger a condition where we negate smallest possible `int` value, which is undefined behaviour. We use a temporary storage as `int64_t` to avoid this bug. Note that this only affects RPC, because we do not parse JSON in the protocol layer, and hence no amendment is needed.
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.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
C++ include guards are used to prevent the contents of a header file from being included multiple times in a single compilation unit. This change renames all `RIPPLE_` and `RIPPLED_` definitions, primarily include guards, to `XRPL_`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
This change adds `STInt32` as a new `SType` under the `STInteger` umbrella, with `SType` value `12`. This is the first and only `STInteger` type that supports negative values.
This change is to improve code coverage (and to simplify #5720 and #5725); there is otherwise no change in functionality. The change adds basic tests for `STInteger` and `STParsedJSON`, so it becomes easier to test smaller changes to the types, as well as removes `STParsedJSONArray`, since it is not used anywhere (including in Clio).
This change fixes the suite names all around the test files, to make them match to the folder name in which this test files are located. Also, the RCL test files are relocated to the consensus folder, because they are testing consensus functionality.
- Specification: https://github.com/XRPLF/XRPL-Standards/pull/272
- Amendment: `TokenEscrow`
- Enables escrowing of IOU and MPT tokens in addition to native XRP.
- Allows accounts to lock issued tokens (IOU/MPT) in escrow objects, with support for freeze, authorization, and transfer rates.
- Adds new ledger fields (`sfLockedAmount`, `sfIssuerNode`, etc.) to track locked balances for IOU and MPT escrows.
- Updates EscrowCreate, EscrowFinish, and EscrowCancel transaction logic to support IOU and MPT assets, including proper handling of trustlines and MPT authorization, transfer rates, and locked balances.
- Enforces invariant checks for escrowed IOU/MPT amounts.
- Extends GatewayBalances RPC to report locked (escrowed) balances.
- Specification: XRPLF/XRPL-Standards#239
- Amendment: `SingleAssetVault`
- Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange.
- A vault can be private or public.
- A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment.
- Shares can be exchanged back into asset with `VaultWithdraw`.
- Permissions on the asset in the vault are transitively applied on shares in the vault.
- Issuer of the asset in the vault can clawback with `VaultClawback`.
- Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.

The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.
Replace Issue in STIssue with Asset. STIssue with MPTIssue is only used in MPT tests.
Will be used in Vault and in transactions with STIssue fields once MPT is integrated into DEX.
`STNumber` lets objects and transactions contain multiple fields for
quantities of XRP, IOU, or MPT without duplicating information about the
"issue" (represented by `STIssue`). It is a straightforward serialization of
the `Number` type that uniformly represents those quantities.

* telENV_RPC_FAILED is a new code, reserved exclusively
for unit tests when RPC fails. This will
make those types of errors distinct and easier to test
for when expected and/or diagnose when not.
* Output RPC command result when result is not expected.
* It is now an invariant that all constructed Public Keys are valid,
non-empty and contain 33 bytes of data.
* Additionally, the memory footprint of the PublicKey class is reduced.
The size_ data member is declared as static.
* Distinguish and identify the PublisherList retrieved from the local
config file, versus the ones obtained from other validators.
* Fixes#2942
* Commit 01c37fe introduced a change to the STTx unit test where a local
"defaultRules" object was created with a temporary inline "presets"
value provided to the ctor. Rules::Impl stores a const ref to the
presets provided to the ctor. This particular call provided an inline
temp variable, which goes out of scope as soon as the object is
created. On Windows, attempting to use the presets (e.g. via the
enabled() function) causes an access violation, which crashes the test
run.
* An audit of the code indicates that all other instances of Rules use
the Application's config.features list, which will have a sufficient
lifetime.
The amendment increases the maximum sign of an account's signer
list from 8 to 32.
Like all new features, the associated amendment is configured with
a default vote of "no" and server operators will have to vote for
it explicitly if they believe it is useful.
In order to preserve the Hooks ABI, it is important that field
values used for hooks be stable going forward.
This commit reserves the required codes so that they will not
be repurposed before Hooks can be proposed for inclusion in
the codebase.
This commit removes the `ltINVALID` pseudo-type identifier from
`LedgerEntryType` and the `ttINVALID` pseudo-type identifier from
`TxType` and includes several small additional improvements that
help to simplify the code base.
It also improves the documentation `LedgerEntryType` and `TxType`,
which was all over the place, and highlights some important caveats
associated with making changes to the ledger and transaction type
identifiers.
The commit also adds a safety check to the `KnownFormats<>` class,
that will catch the the accidental reuse of format identifiers.
Ideally, this should be done at compile time but C++ does not (yet?)
allow for the sort of introspection that would enable this.
While most of the code associated with secp256k1 operations had
been migrated to libsecp256k1, the deterministic key derivation
code was still using calls to OpenSSL.
If merged, this commit replaces the OpenSSL-based routines with
new libsecp256k1-based implementations. No functional change is
expected and the change should be transparent.
This commit also removes several support classes and utility
functions that wrapped or adapted various OpenSSL types that
are no longer needed.
A tip of the hat to the original author of this truly superb
library, Dr. Pieter Wuille, and to all other contributors.
- Simplify and consolidate code for parsing hex input.
- Replace beast::endian::order with boost::endian::order.
- Simplify CountedObject code.
- Remove pre-C++17 workarounds in favor of C++17 based solutions.
- Improve `base_uint` and simplify its hex-parsing interface by
consolidating the `SexHex` and `SetHexExact` methods into one
API: `parseHex` which forces callers to verify the result of
the operation; as a result some public-facing API endpoints
may now return errors when passed values that were previously
accepted.
- Remove the simple fallback implementations of SHA2 and RIPEMD
introduced to reduce our dependency on OpenSSL. The code is
slow and rarely, if ever, exercised and we rely on OpenSSL
functionality for Boost.ASIO as well.
Tickets are a mechanism to allow for the "out-of-order" execution of
transactions on the XRP Ledger.
This commit, if merged, reworks the existing support for tickets and
introduces support for 'ticket batching', completing the feature set
needed for tickets.
The code is gated under the newly-introduced `TicketBatch` amendment
and the `Tickets` amendment, which is not presently active on the
network, is being removed.
The specification for this change can be found at:
https://github.com/xrp-community/standards-drafts/issues/16
If the 'HardenedValidations' amendment is enabled, this commit will
track the version of the software that validators embed in their
validations.
If a server notices that at least 60% of the validators on its UNL
are running a newer version than it is running, it will periodically
print an informational message, reminding the operator to check for
update.
In deciding whether to relay a proposal or validation, a server would
consider whether it was issued by a validator on that server's UNL.
While both trusted proposals and validations were always relayed,
the code prioritized relaying of untrusted proposals over untrusted
validations. While not technically incorrect, validations are
generally more "valuable" because they are required during the
consensus process, whereas proposals are not, strictly, required.
The commit introduces two new configuration options, allowing server
operators to fine-tune the relaying behavior:
The `[relay_proposals]` option controls the relaying behavior for
proposals received by this server. It has two settings: "trusted"
and "all" and the default is "trusted".
The `[relay_validations]` options controls the relaying behavior for
validations received by this server. It has two settings: "trusted"
and "all" and the default is "all".
This change does not require an amendment as it does not affect
transaction processing.
This commit removes obsolete comments, dead or no longer useful
code, and workarounds for several issues that were present in older
compilers that we no longer support.
Specifically:
- It improves the transaction metadata handling class, simplifying
its use and making it less error-prone.
- It reduces the footprint of the Serializer class by consolidating
code and leveraging templates.
- It cleanups the ST* class hierarchy, removing dead code, improving
and consolidating code to reduce complexity and code duplication.
- It shores up the handling of currency codes and the conversation
between 160-bit currency codes and their string representation.
- It migrates beast::secure_erase to the ripple namespace and uses
a call to OpenSSL_cleanse instead of the custom implementation.
