This amendment fixes an edge case where an empty DID object can be
created. It adds an additional check to ensure that DIDs are
non-empty when created, and returns a `tecEMPTY_DID` error if the DID
would be empty.
* 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.
We are currently using old version 0.6.2 of `xxhash`, as a verbatim copy and paste of its header file `xxhash.h`. Switch to the more recent version 0.8.2. Since this version is in Conan Center (and properly protects its ABI by keeping the state object incomplete), add it as a Conan requirement. Switch to the SIMD instructions (in the new `XXH3` family) supported by the new version.
This algorithm is about an order of magnitude faster than the existing
algorithm (about 10x faster for encoding and about 15x faster for
decoding - including the double hash for the checksum). The algorithms
use gcc's int128 (fast MS version will have to wait, in the meantime MS
falls back to the slow code).
* 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
The compilation fails due to an issue in the initializer list
of an optional argument, which holds a vector of pairs.
The code compiles correctly on earlier gcc versions, but fails on gcc 13.
Implement native support for Price Oracles.
A Price Oracle is used to bring real-world data, such as market prices,
onto the blockchain, enabling dApps to access and utilize information
that resides outside the blockchain.
Add Price Oracle functionality:
- OracleSet: create or update the Oracle object
- OracleDelete: delete the Oracle object
To support this functionality add:
- New RPC method, `get_aggregate_price`, to calculate aggregate price for a token pair of the specified oracles
- `ltOracle` object
The `ltOracle` object maintains:
- Oracle Owner's account
- Oracle's metadata
- Up to ten token pairs with the scaled price
- The last update time the token pairs were updated
Add Oracle unit-tests
Add a new RPC / WS call for `server_definitions`, which returns an
SDK-compatible `definitions.json` (binary enum definitions) generated by
the server. This enables clients/libraries to dynamically work with new
fields and features, such as ones that may become available on side
chains. Clients query `server_definitions` on a node from the network
they want to work with, and immediately know how to speak that node's
binary "language", even if new features are added to it in the future
(as long as there are no new serialized types that the software doesn't
know how to serialize/deserialize).
Example:
```js
> {"command": "server_definitions"}
< {
"result": {
"FIELDS": [
[
"Generic",
{
"isSerialized": false,
"isSigningField": false,
"isVLEncoded": false,
"nth": 0,
"type": "Unknown"
}
],
[
"Invalid",
{
"isSerialized": false,
"isSigningField": false,
"isVLEncoded": false,
"nth": -1,
"type": "Unknown"
}
],
[
"ObjectEndMarker",
{
"isSerialized": false,
"isSigningField": true,
"isVLEncoded": false,
"nth": 1,
"type": "STObject"
}
],
...

A large synthetic offer was not handled correctly in the payment engine.
This patch fixes that issue and introduces a new invariant check while
processing synthetic offers.
* 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.
Add `STObject` constructor to explicitly set the inner object template.
This allows certain AMM transactions to apply in the same ledger:
There is no issue if the trading fee is greater than or equal to 0.01%.
If the trading fee is less than 0.01%, then:
- After AMM create, AMM transactions must wait for one ledger to close
(3-5 seconds).
- After one ledger is validated, all AMM transactions succeed, as
appropriate, except for AMMVote.
- The first AMMVote which votes for a 0 trading fee in a ledger will
succeed. Subsequent AMMVote transactions which vote for a 0 trading
fee will wait for the next ledger (3-5 seconds). This behavior repeats
for each ledger.
This has no effect on the ultimate correctness of AMM. This amendment
will allow the transactions described above to succeed as expected, even
if the trading fee is 0 and the transactions are applied within one
ledger (block).
Prior to this commit, `port_grpc` could not be added to the [server]
stanza. Instead of validating gRPC IP/Port/Protocol information in
ServerHandler, validate grpc port info in GRPCServer constructor. This
should not break backwards compatibility.
gRPC-related config info must be in a section (stanza) called
[port_gprc].
* Close#4015 - That was an alternate solution. It was decided that with
relaxed validation, it is not necessary to rename port_grpc.
* Fix#4557
Without this amendment, an NFTokenAcceptOffer transaction can succeed
even when the NFToken recipient does not have sufficient reserves for
the new NFTokenPage. This allowed accounts to accept NFT sell offers
without having a sufficient reserve. (However, there was no issue in
brokered mode or when a buy offer is involved.)
Instead, the transaction should fail with `tecINSUFFICIENT_RESERVE` as
appropriate. The `fixNFTokenReserve` amendment adds checks in the
NFTokenAcceptOffer transactor to check if the OwnerCount changed. If it
did, then it checks the new reserve requirement.
Fix#4679
Use consistent platform-agnostic library names on all platforms.
Fix an issue that prevents dependents like validator-keys-tool from
linking to libxrpl on Windows.
It is bad practice to change the binary base name depending on the
platform. CMake already manipulates the base name into a final name that
fits the conventions of the platform. Linkers accept base names on the
command line and then look for conventional names on disk.
* Add logging for Application.cpp sweep()
* Improve lifetime management of ledger objects (`SLE`s)
* Only store SLE digest in CachedView; get SLEs from CachedSLEs
* Also force release of last ledger used for path finding if there are
no path finding requests to process
* Count more ST objects (derive from `CountedObject`)
* Track CachedView stats in CountedObjects
* Rename the CachedView counters
* Fix the scope of the digest lookup lock
Before this patch, if you asked "is it caching?" It was always caching.
Prevent WebSocket connections from trying to close twice.
The issue only occurs in debug builds (assertions are disabled in
release builds, including published packages), and when the WebSocket
connections are unprivileged. The assert (and WRN log) occurs when a
client drives up the resource balance enough to be forcibly disconnected
while there are still messages pending to be sent.
Thanks to @lathanbritz for discovering this issue in #4822.
Workaround for compilation errors with gcc-13 and other compilers
relying on `libstdc++` version 13. This is temporary until actual fix is
available for us to use: https://github.com/boostorg/beast/pull/2682
Some boost.beast files (which we do use) rely on an old gcc-12 behaviour
where `#include <cstdint>` was not needed even though types from this
header were used. This was broken by a change in libstdc++ version 13:
https://gcc.gnu.org/gcc-13/porting_to.html#header-dep-changes
The necessary fix was implemented in boost.beast, however it is not yet
available. Until it is available, we can use this workaround to enable
compilation of `rippled` with gcc-13, clang-16, etc.

Introduce the `fixFillOrKill` amendment.
Fix an edge case occurring when an offer with `tfFillOrKill` set (but
without `tfSell` set) fails to cross an offer with a better rate. If
`tfFillOrKill` is set, then the owner must receive the full TakerPays.
Without this amendment, an offer fails if the entire `TakerGets` is not
spent. With this amendment, when `tfSell` is not set, the entire
`TakerGets` does not have to be spent.

Remove dependency on `<ranges>` header, since it is not implemented by
all compilers which we want to support.
This code change only affects unit tests.
Resolve https://github.com/XRPLF/rippled/issues/4787
Remove `tx_history` and `ledger_header` methods from API version 2.
Update `RPC::Handler` to allow for methods (or method implementations)
to be API version specific. This partially resolves#4727. We can now
store multiple handlers with the same name, as long as they belong to
different (non-overlapping) API versions. This necessarily impacts the
handler lookup algorithm and its complexity; however, there is no
performance loss on x86_64 architecture, and only minimal performance
loss on arm64 (around 10ns). This design change gives us extra
flexibility evolving the API in the future, including other parts of
In API version 2, `tx_history` and `ledger_header` are no longer
recognised; if they are called, `rippled` will return error

Using the "Amount" field in Payment transactions can cause incorrect
interpretation. There continue to be problems from the use of this
field. "Amount" is rarely the correct field to use; instead,
"delivered_amount" (or "DeliveredAmount") should be used.
Rename the "Amount" field to "DeliverMax", a less misleading name. With
api_version: 2, remove the "Amount" field from Payment transactions.
- Input: "DeliverMax" in `tx_json` is an alias for "Amount"
- sign
- submit (in sign-and-submit mode)
- submit_multisigned
- sign_for
- Output: Add "DeliverMax" where transactions are provided by the API
- ledger
- tx
- tx_history
- account_tx
- transaction_entry
- subscribe (transactions stream)
- Output: Remove "Amount" from API version 2
Fix#3484Fix#3902
Implement native support for W3C DIDs.
Add a new ledger object: `DID`.
Add two new transactions:
1. `DIDSet`: create or update the `DID` object.
2. `DIDDelete`: delete the `DID` object.
This meets the requirements specified in the DID v1.0 specification
currently recommended by the W3C Credentials Community Group.
The DID format for the XRP Ledger conforms to W3C DID standards.
The objects can be created and owned by any XRPL account holder.
The transactions can be integrated by any service, wallet, or application.
It might be possible for the server code to indirect through certain
`end()` iterators. While a debug build would catch this problem with
`assert()`s, a release build would crash. If there are problems in this
area in the future, it is best to get a definitive indication of the
nature of the error regardless of whether it's a debug or release build.
To accomplish this, these `assert`s are converted into `LogicError`s
that will produce a reasonable error message when they fire.
The assert is saying that the only reason `pathFinder` would be null is
if the request was aborted (connection dropped, etc.). That's what
`continueCallback()` checks. But that is very clearly not true if you
look at `getPathFinder`, which calls `findPaths`, which can return false
for many reasons.
Fix#4744
Context: The `DisallowIncoming` amendment provides an option to block
incoming trust lines from reaching your account. The
asfDisallowIncomingTrustline AccountSet Flag, when enabled, prevents any
incoming trust line from being created. However, it was too restrictive:
it would block an issuer from authorizing a trust line, even if the
trust line already exists. Consider:
1. Issuer sets asfRequireAuth on their account.
2. User sets asfDisallowIncomingTrustline on their account.
3. User submits tx to SetTrust to Issuer.
At this point, without `fixDisallowIncomingV1` active, the issuer would
not be able to authorize the trust line.
The `fixDisallowIncomingV1` amendment, once activated, allows an issuer
to authorize a trust line even after the user sets the
asfDisallowIncomingTrustline flag, as long as the trust line already
exists.
When a new transactor is added, there are several places in applySteps
that need to be modified. This patch refactors the code so only one
function needs to be modified.
Make transactions and pseudo-transactions share the same commonFields
again. This regularizes the code in a nice way.
While this technically allows pseudo-transactions to have a
TicketSequence field, pseudo-transactions are only ever constructed by
code paths that don't add such a field, so this is not a transaction
processing change. It may be possible to add a separate check to ensure
TicketSequence (and other fields that don't make sense on
pseudo-transactions) are never added to pseudo-transactions, but that
should not be necessary. (TicketSequence is not the only common field
that can not and does not appear in pseudo-transactions.) Note:
TicketSequence is already documented as a common field.
Related: #4637Fix#4714
Modify the `XChainBridge` amendment.
Before this patch, two door accounts on the same chain could could own
the same bridge spec (of course, one would have to be the issuer and one
would have to be the locker). While this is silly, it does not violate
any bridge invariants. However, on further review, if we allow this then
the `claim` transactions would need to change. Since it's hard to see a
use case for two doors to own the same bridge, this patch disallows
it. (The transaction will return tecDUPLICATE).
Amendment "flapping" (an amendment repeatedly gaining and losing
majority) usually occurs when an amendment is on the verge of gaining
majority, and a validator not in favor of the amendment goes offline or
loses sync. This fix makes two changes:
1. The number of validators in the UNL determines the threshold required
for an amendment to gain majority.
2. The AmendmentTable keeps a record of the most recent Amendment vote
received from each trusted validator (and, with `trustChanged`, stays
up-to-date when the set of trusted validators changes). If no
validation arrives from a given validator, then the AmendmentTable
assumes that the previously-received vote has not changed.
In other words, when missing an `STValidation` from a remote validator,
each server now uses the last vote seen. There is a 24 hour timeout for
recorded validator votes.
These changes do not require an amendment because they do not impact
transaction processing, but only the threshold at which each individual
validator decides to propose an EnableAmendment pseudo-transaction.
Fix#4350
Fix the Windows build by using `unsigned int` (instead of `uint`).
The error, introduced by #4618, looks something like:
rpc\impl\RPCHelpers.h(299,5): error C2061: syntax error: identifier
'uint' (compiling source file app\ledger\Ledger.cpp)
A few methods, including `book_offers`, take currency codes as
parameters. The XRPL doesn't care if the letters in those codes are
lowercase or uppercase, as long as they come from an alphabet defined
internally. rippled doesn't care either, when they are submitted in a
hex representation. When they are submitted in an ASCII string
representation, rippled, but not XRPL, is more restrictive, preventing
clients from interacting with some currencies already in the XRPL.
This change gets rippled out of the way and lets clients submit currency
codes in ASCII using the full alphabet.
Fixes#4112
