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.

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

- transaction_entry
- subscribe (transactions stream)

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.

Copy the new code to `src/secp256k1` without changes:
`src/secp256k1` is identical to bitcoin-core/secp256k1@acf5c55 (v0.3.2).
We could consider changing to a Git submodule, though that would require
changes to the build instructions because we are not using submodules
anywhere else.
Remove the `verify` and `message` function declarations. The explicit
instantiation requests could not be completed because there were no
implementations for those two member functions. It is helpful that the
Microsoft (MSVC) compiler on Windows appears to be strict when it comes
to template instantiation.
This resolves the warning:

A bridge connects two blockchains: a locking chain and an issuing
chain (also called a mainchain and a sidechain). Both are independent
ledgers, with their own validators and potentially their own custom
transactions. Importantly, there is a way to move assets from the
locking chain to the issuing chain and a way to return those assets from
the issuing chain back to the locking chain: the bridge. This key
operation is called a cross-chain transfer. A cross-chain transfer is
not a single transaction. It happens on two chains, requires multiple
transactions, and involves an additional server type called a "witness".
A bridge does not exchange assets between two ledgers. Instead, it locks
assets on one ledger (the "locking chain") and represents those assets
with wrapped assets on another chain (the "issuing chain"). A good model
to keep in mind is a box with an infinite supply of wrapped assets.
Putting an asset from the locking chain into the box will release a
wrapped asset onto the issuing chain. Putting a wrapped asset from the
issuing chain back into the box will release one of the existing locking
chain assets back onto the locking chain. There is no other way to get
assets into or out of the box. Note that there is no way for the box to
"run out of" wrapped assets - it has an infinite supply.

For the `account_tx` and `noripple_check` methods, perform input
validation for optional parameters such as "binary", "forward",
"strict", "transactions". Previously, when these parameters had invalid
values (e.g. not a bool), no error would be returned. Now, it returns an
`invalidParams` error.
* This updates the behavior to match Clio
(https://github.com/XRPLF/clio).
* Since this is potentially a breaking change, it only applies to
requests specifying api_version: 2.
* Fix#4543.
Minor refactor to `TxFormats.cpp`:
- Rename `commonFields` to `pseudoCommonFields` (since it is the common fields
that all pseudo-transactions need)
- Add a new static variable, `commonFields`, which represents all the common
fields that non-pseudo transactions need (essentially everything that
`pseudoCommonFields` contains, plus `sfTicketSequence`)
This makes it harder to accidentally leave out `sfTicketSequence` in a new
transaction.
- Verify "check", used to retrieve a Check object, is a string.
- Verify "nft_page", used to retrieve an NFT Page, is a string.
- Verify "index", used to retrieve any type of ledger object by its
unique ID, is a string.
- Verify "directory", used to retrieve a DirectoryNode, is a string or
an object.
This change only impacts api_version 2 since it is a breaking change.

- Update amm_info to fetch AMM by amm account id.
- This is an additional way to retrieve an AMM object.
- Alternatively, AMM can still be fetched by the asset pair as well.
- Add owner directory entry for AMM object.
Context:
- Add back the AMM object directory entry, which was deleted by #4626.
- This fixes `account_objects` for `amm` type.
Modify two error cases in AMMBid transactor to return `tecINTERNAL` to
more clearly indicate that these errors should not be possible unless
operating in unforeseen circumstances. It likely indicates a bug.
The log level has been updated to `fatal()` since it indicates a
(potentially network-wide) unexpected condition when either of these
errors occurs.
Details:
The two specific transaction error cases changed are:
- `tecAMM_BALANCE` - In this case, this error (total LP Tokens
outstanding is lower than the amount to be burned for the bid) is a
subset of the case where the user doesn't have enough LP Tokens to pay
for the bid. When this case is reached, the bidder's LP Tokens balance
has already been checked first. The user's LP Tokens should always be
a subset of total LP Tokens issued, so this should be impossible.
- `tecINSUFFICIENT_PAYMENT` - In this case, the amount to be refunded as
a result of the bid is greater than the price paid for the auction
slot. This should never occur unless something is wrong with the math
for calculating the refund amount.
Both error cases in question are "defense in depth" measures meant to
protect against making things worse if the code has already reached a
state that is supposed to be impossible, likely due to a bug elsewhere.
Such "shouldn't ever occur" checks should use an error code that
categorically indicates a larger problem. This is similar to how
`tecINVARIANT_FAILED` is a warning sign that something went wrong and
likely could've been worse, but since there isn't an Invariant Check
applying here, `tecINTERNAL` is the appropriate error code.
This is "debatably" a transaction processing change since it could
hypothetically change how transactions are processed if there's a bug we
don't know about.
Introduce a new variadic template helper function, `forAllApiVersions`,
that accepts callables to execute a set of functions over a range of
versions - from RPC::apiMinimumSupportedVersion to RPC::apiBetaVersion.
This avoids the duplication of code.
Context: #4552
- "Rename" the type `LedgerInfo` to `LedgerHeader` (but leave an alias
for `LedgerInfo` to not yet disturb existing uses). Put it in its own
public header, named after itself, so that it is more easily found.
- Move the type `Fees` and NFT serialization functions into public
(installed) headers.
- Compile the XRPL and gRPC protocol buffers directly into `libxrpl` and
install their headers. Fix the Conan recipe to correctly export these
types.
Addresses change (2) in
https://github.com/XRPLF/XRPL-Standards/discussions/121.
For context: This work supports Clio's dependence on libxrpl. Clio is
just an example consumer. These changes should benefit all current and
future consumers.

When an AMM account is deleted, the owner directory entries must be
deleted in order to ensure consistent ledger state.
* When deleting AMM account:
* Clean up AMM owner dir, linking AMM account and AMM object
* Delete trust lines to AMM
* Disallow `CheckCreate` to AMM accounts
* AMM cannot cash a check
* Constrain entries in AuthAccounts array to be accounts
* AuthAccounts is an array of objects for the AMMBid transaction
* SetTrust (TrustSet): Allow on AMM only for LP tokens
* If the destination is an AMM account and the trust line doesn't
exist, then:
* If the asset is not the AMM LP token, then fail the tx with
`tecNO_PERMISSION`
* If the AMM is in empty state, then fail the tx with `tecAMM_EMPTY`
* This disallows trustlines to AMM in empty state
* Add AMMID to AMM root account
* Remove lsfAMM flag and use sfAMMID instead
* Remove owner dir entry for ltAMM
* Add `AMMDelete` transaction type to handle amortized deletion
* Limit number of trust lines to delete on final withdraw + AMMDelete
* Put AMM in empty state when LPTokens is 0 upon final withdraw
* Add `tfTwoAssetIfEmpty` deposit option in AMM empty state
* Fail all AMM transactions in AMM empty state except special deposit
* Add `tecINCOMPLETE` to indicate that not all AMM trust lines are
deleted (i.e. partial deletion)
* This is handled in Transactor similar to deleted offers
* Fail AMMDelete with `tecINTERNAL` if AMM root account is nullptr
* Don't validate for invalid asset pair in AMMDelete
* AMMWithdraw deletes AMM trust lines and AMM account/object only if the
number of trust lines is less than max
* Current `maxDeletableAMMTrustLines` = 512
* Check no directory left after AMM trust lines are deleted
* Enable partial trustline deletion in AMMWithdraw
* Add `tecAMM_NOT_EMPTY` to fail any transaction that expects an AMM in
empty state
* Clawback considerations
* Disallow clawback out of AMM account
* Disallow AMM create if issuer can claw back
This patch applies to the AMM implementation in #4294.
