The rdb module was not properly designed, which is fixed in this change. The module had three classes:
1) The abstract class `RelationalDB`.
2) The abstract class `SQLiteDatabase`, which inherited from `RelationalDB` and added some pure virtual methods.
3) The concrete class `SQLiteDatabaseImp`, which inherited from `SQLiteDatabase` and implemented all methods.
The updated code simplifies this as follows:
* The `SQLiteDatabaseImp` has become `SQLiteDatabase`, and
* The former `SQLiteDatabase `has merged with `RelationalDatabase`.
This change modularizes the `WalletDB` and `Manifest`. Note that the wallet db has nothing to do with account wallets and it stores node configuration, which is why it depends on the manifest code.
This change removes the cache in `DatabaseNodeImp` and simplifies the caching logic in `SHAMapStoreImp`. As NuDB and RocksDB internally already use caches, additional caches in the code are not very valuable or may even be unnecessary, as also confirmed during preliminary performance analyses.
The `ManifestCache::applyManifest` function was returning early without incrementing `seq_`. `OverlayImpl `uses this sequence to identify/invalidate a cached `TMManifests` message, which is exchanged with peers on connection. Depending on network size, startup sequencing, and topology, this can cause syncing issues. This change therefore increments `seq_` when a new manifest is accepted.
This change introduces the `fixExpiredNFTokenOfferRemoval` amendment that allows expired offers to pass through `preclaim()` and be deleted in `doApply()`, following the same pattern used for expired credentials.
Since the minimum Clang version we support is 16, the checks for version < 15 are no longer necessary. This change therefore removes the macros checking if the clang version is < 15 and simplifies uses of `std::source_location`.
This change continues the thread naming work from #5691 and #5758, which enables more useful lock contention profiling by ensuring threads/jobs have short, stable, human-readable names (rather than being truncated/failing due to OS limits). This changes diagnostic naming only (thread names and job/load-event labels), not behavior.
Specific modifications are:
* Shortens all thread/job names used with `beast::setCurrentThreadName`, so the effective Linux thread name stays within the 15-character limit.
* Removes per-ledger sequence numbers from job/thread names to avoid long labels. This improves aggregation in lock contention profiling for short-lived job executions.
`PeerImp` processes `TMGetObjectByHash` queries with an unbounded per-request loop, which performs a `NodeStore` fetch and then appends retrieved data to the reply for each queried object without a local count cap or reply-byte budget. However, the `Nodestore` fetches are expensive when high in numbers, which might slow down the process overall. Hence this code change adds an upper cap on the response size.
These "fixed location" objects can be found in multiple ways:
1. The lookup parameters use the same format as other ledger objects, but the only valid value is true or the valid index of the object:
- Amendments: "amendments" : true
- FeeSettings: "fee" : true
- NegativeUNL: "nunl" : true
- LedgerHashes: "hashes" : true (For the "short" list. See below.)
2. With RPC API >= 3, using special case values to "index", such as "index" : "amendments". Uses the same names as above. Note that for "hashes", this option will only return the recent ledger hashes / "short" skip list.
3. LedgerHashes has two types: "short", which stores recent ledger hashes, and "long", which stores the flag ledger hashes for a particular ledger range.
- To find a "long" LedgerHashes object, request '"hashes" : <ledger sequence>'. <ledger sequence> must be a number that evaluates to an unsigned integer.
- To find the "short" LedgerHashes object, request "hashes": true as with the other fixed objects.
The following queries are all functionally equivalent:
- "amendments" : true
- "index" : "amendments" (API >=3 only)
- "amendments" : "7DB0788C020F02780A673DC74757F23823FA3014C1866E72CC4CD8B226CD6EF4"
- "index" : "7DB0788C020F02780A673DC74757F23823FA3014C1866E72CC4CD8B226CD6EF4"
Finally, whether the object is found or not, if a valid index is computed, that index will be returned. This can be used to confirm the query was valid, or to save the index for future use.
The word `failed` in the test case makes it hard to search through the test logs when an actual test failure occurs, so this change renames the word to just `fail` instead.
- 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.

- Spec: XLS-66
Fix overpayment asserts (#6084)
MPTTester::operator() parameter should be std::int64_t
- Originally defined as uint64_t, but the testIssuerLoan() test called
it with a negative number, causing an overflow to a very large number
that in some circumstances could be silently cast back to an int64_t,
but might not be. I believe this is UB, and we don't want to rely on
that.
Review feedback from @Tapanito: overpayment value change
- In overpayment results, the management fee was being calculated twice:
once as part of the value change, and as part of the fees paid.
Exclude it from the value change.
Fix Overpayment Calculation (#6087)
- Adds additional unit tests to cover math calculations.
- Removes unused methods.
Review feedback from @shawnxie999: even more rounding
- Round the initial total value computation upward, unless there is
0-interest.
- Rename getVaultScale to getAssetsTotalScale, and convert one incorrect
computation to use it.
- Use adjustImpreciseNumber for LossUnrealized.
- Add some logging to computeLoanProperties.
Fix LoanBrokerSet debtMaximum limits (#6116)
Fix some minor bugs in Lending Protocol (#6101)
- add nodiscard to unimpairLoan, and check result in LoanPay
- add a check to verify that issuer exists
- improve LoanManage error code for dust amounts
Check permissions in LoanSet and LoanPay (#6108)
Disallow pseudo accounts to be Destination for LoanBrokerCoverWithdraw (#6106)
Ensure vault asset cap is not exceeded (#6124)
Fix Overpayment ValueChange calculation in Lending Protocol (#6114)
- Adds loan state to LoanProperties.
- Cleans up computeLoanProperties.
- Fixes missing management fee from overpayment.
fix: Enable LP Deposits when the broker is the asset issuer (#6119)
* Replace accountHolds with accountSpendable when checking
for account funds in VaultDeposit and LoanBrokerCoverDeposit
Add a few minor changes (#6158)
- Updates or fixes a couple of things I noticed while reviewing changes
to the spec.
- Rename sfPreviousPaymentDate to sfPreviousPaymentDueDate.
- Make the vault asset cap check added in #6124 a little more robust:
1. Check in preflight if the vault is _already_ over the limit.
2. Prevent overflow when checking with the loan value. (Subtract
instead of adding, in case the values are near maxint. Both return
the same result. Also add a unit test so each case is covered.
Add minimum grace period validation (#6133)
Fix bugs: frozen pseudo-account, and FLC cutoff (#6170)
refactor: Rename raw state to theoretical state (#6187)
Check if a withdrawal amount exceeds any applicable receiving limit. (#6117)
Fix overpayment result calculation (#6195)
Address review feedback from Lending Protocol re-review (#6161)

- Introduces amendment `fixBatchInnerSigs`
- Update Batch unit tests
- Fix all the Env instantiations to _use_ the "features" parameter.
- testInnerSubmitRPC runs with Batch enabled and disabled.
- Add a test to testInnerSubmitRPC for a correctly signed tx incorrectly
using the tfInnerBatchTxn flag.
- Generalize the submitAndValidate lambda in testInnerSubmitRPC.
- With the fix amendment, a transaction never reaches the transaction
engine (Transactor and derived classes.)
- Test submitting a pseudo-transaction. Stopped before reaching the
transaction engine, but with different errors.
- The tests verify that without the amendment, a transaction with
tfInnerBatchTxn is immediately rejected. Without the amendment, things
are safe. The amendment just makes things safer and more future-proof.
- Adds a mechanism for the vault owner to burn user shares when the vault is stuck. If the Vault has 0 AssetsAvailable and Total, the owner may submit a VaultClawback to reclaim the worthless fees, and thus allow the Vault to be deleted. The Amount must be left off (unless the owner is the asset issuer), specified as 0 Shares, or specified as the number of Shares held.
This change:
* Truncates thread names if more than 15 chars with `snprintf`.
* Adds warnings for truncated thread names if `-DTRUNCATED_THREAD_NAME_LOGS=ON`.
* Add a static assert for string literals to stop compiling if > 15 chars.
* Shortens `Resource::Manager` to `Resource::Mngr` to fix the static assert failure.
* Updates `CurrentThreadName_test` unit test specifically for Linux to verify truncation.
This change fixes the last of the spelling issues, and enables the pre-commit (and CI) check for spelling. There are no functionality changes, but it does rename some enum values.
This change adds some basic tests for all the `ledger_entry` helper functions, so each ledger entry type is covered. There are further some minor refactors in `parseAMM` to provide better error messages. Finally, to improve readability, alphabetization was applied in the helper functions.
This change renames all occurrences of `rippled.cfg` to `xrpld.cfg`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts. For the time being it maintains support for `rippled.cfg` as config file, if `xrpld.cfg` does not exist.
`Json::Object` and related objects are not used at all, so this change removes `include/xrpl/json/Object.h` and all downstream files. There are a number of minor downstream changes as well.
Full list of deleted classes and functions:
* `Json::Collections`
* `Json::Object`
* `Json::Array`
* `Json::WriterObject`
* `Json::setArray`
* `Json::addObject`
* `Json::appendArray`
* `Json::appendObject`
The last helper function, `copyFrom`, seemed a bit more complex and was actually used in a few places, so it was moved to `LedgerToJson.h` instead of deleting it.
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.
This change renames all the `info()` functions to `header()`, since they return `LedgerHeader` structs. It also renames the underlying variables from `info_` to `header_`.
This PR renames `LedgerInfo` to `LedgerHeader`. Namely, `LedgerInfo` was already an alias for `LedgerHeader`, and the comments next to the alias suggested that it would make sense to rename it, since that makes it clearer what it is.
This PR cleans up `RPCHelpers.h` and `RPCHelpers.cpp`. It splits out all the fetch-ledger functions to a new set of files, `RPCLedgerHelpers.h`/`RPCLedgerHelpers.cpp`, and moves the general-API functions to `ApiVersion.h`. There is no functionality change.
- 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.
