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.
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.
