There was a problem hiding this comment.
Isn't this supposed to be `... !isTesSuccess(ret))
- Add the LendingProtocol amendment
- Add Loan Broker and Loan ledger objects:
- Also add new SFields, Keylet functions, and an Invariant to verify no
illegal field modification
- Update list of "constant" fields from spec
- Also add a general check for all object types for the type and index
fields
- refactor: Check transaction flags in preflight0
- Adds a flagMask parameter to preflight1 so that it's impossible to
forget to check flags.
- Also adds a short hash prefix to all Transactor log messages.
- refactor: Generalize Transactor preflight:
- Derived classes no longer need to explicitly check amendments, nor
call into preflight1 or preflight2.
- implemeng LoanBrokerSet
- Transactions: LoanDelete, LoanManage, LoanDraw, LoanPay
- LoanBrokerSet creation mostly done. Need update.
- Also added a lookup table for pseudo account fields.
- Update changed field name.
- Modify modifiable fields in an update. Note there are only two.
- Add a node field to dirLink, defaulting sfOwnerNode, so other
relationships can be updated.
- Create some helper classes for transaction fields
- Test that they work by converting some of the existing classes
- Finish creating helper classes for JTx fields
- Also change the pseudo account field lookup to a function that uses
a switch
- Update tests, update pseudo-account checking
- Generalize some of the Invariant checks using macro files
- Valid ledger entry type
- Valid new account root and pseudo account check
- Enumerate transaction privileges for invariants
- Allows them to be defined in transactions.macro instead of needing to
scrutinize every existing Invariant class.
- List is not necessarily comprehensive, but does cover every check
where more than one transaction type is involved.
- Reserve a few values between Vault and Lending for future use
- Pseudo-account improvements
- Define pseudo-account fields with an sfield flag
- Pseudo-account invariant checks rules whenever a pseudo-account is
created or modified.
- Move some helper functions.
- Check the regular key in the pseudo-transaction invariant check.
- Transactor::checkSign will always fail for a pseudo-account, so even
if someone figures out how to get a good signature, it won't work.
- Fix account creation to check both amendments
- Add a validity range for sfDebtMaximum
- Change more "failed" messages. The goal here is to be able to search
the log for "failed" and ONLY get test failures.
- NoModifiedUnmodifiableFields and ValidPseudoAccounts
- Move the Invariants_test class into the test namespace
- Clang wants an explicit ctor to emplace in a vector
- Refactor: Add a Transactor base function to make it easier to get the
owner reserve increment as a fee.
- Refactor: Add an overload jtx::fee(increment) to pay an owner reserve.
- Initial implementation of LoanBrokerDelete
- Generalize the LoanBroker lifecycle test
- Refactor ApplyView::dirAdd to give access to low-level operations
- Takes a page from #5362, which may turn out to be useful!
- Start writing Loan Broker invariants and tests
- Specifically those mentioned for LoanBrokerDelete
- Move all detail namespaces to be under ripple
- Avoids problems with namespace collisions / ambiguous symbol issues
with unity builds, especially when adding or removing files.
- Add LoanBrokerCoverDeposit transaction
- Add LoanBrokerCoverWithdraw transaction
- Start writing tests for LoanBrokerCover*
- Add support for `Asset` and `MPTIssue` to some `jtx` helper classes
and functions (`balance`, `expectLine`)
- Add support for pseudo-accounts to `jtx::Account` by allowing directly
setting the AccountID without a matching key.
- Add Asset and MPTIssue support to more jtx objects / functions
- Unfortunately, to work around some ambiguous symbol compilation
errors, I had to change the implicit conversion from IOU to Asset to
a conversion from IOU to PrettyAsset, and add a more explicit
`asset()` function. This workaround only required changing two
existing tests, so seems acceptable.
- Ensure that an account is not deleted with an XRP balance
- Updates the AccountRootsDeletedClean invariant
- Finish up the Loan Broker tests
- Move inclusion of Transactor headers to transactions.macro
- Only need to update in one place when adding a new transaction.
- Start implementing LoanSet transactor
- Add some more values and functions to make it easier to work with
basis point values / bips.
- Fix several earlier mistakes.
- Generalize the check*Sign functions to support CounterParty
- checkSign, checkSingleSign, and checkMultiSign in STTx and Transactor
- Start writing Loan tests
- Required adding support for counterparty signature to jtx framework:
arbitrary signature field destination, multiple signer callbacks
- Get Counterparty signing working
- Add more LoanSet unit tests, added LoanBroker LoanSequence field
- LoanSequence will prevent loan key collisions
- Change Loan object indexing, fix several broken LoanSet unit tests
- Loan objects will now only be indexed by LoanBrokerID and
LoanSequence, which is a new field in LoanBroker. Also changes
Loan.Sequence to Loan.LoanSequence to match up.
- Several tests weren't working because of `PrettyAsset` scaling. Also,
`PrettyAsset` calculations could overflow. Made that less likely by
changing the type of `scale_`.
- LoanSet will fail if an account tries to loan to itself.
- Ensure that an account is not deleted with a non-zero owner count
- Updates the AccountRootsDeletedClean invariant
- Add unit tests to create a Loan successfully
- Fix a few field initializations in LoanSet
- Refactor issuance validity check in VaultCreate
- Utility function: canAddHolding
- Call canAddHolding from any transactor that call addEmptyHolding
(LoanBrokerSet, LoanSet)
- Start implementing LoanManage transaction
- Also add a ValidLoan invariant
- Finish `LoanManage` functionality and tests, modulo LoanDraw/Pay
- Allow existing trust lines to loan brokers to be managed (by issuer)
- Implement LoanDelete, and fix a bunch of math errors in LoanManage
- Update to match latest spec: compute interest, LoanBroker reserves
- refactor: Define getFlagsMask in the base Transactor class
- Returns tfUniversalMask for most transactors
- Only transactors that use other flags need to override
- Implement LoanDraw, and made good progress on related tests
- Start implementing LoanPay transaction
- Implement LoanPay & most tests
- Also add an XRPL_ASSERT_PARTS, which splits the parts of the assert message
so I don't have to remember the proper formatting.
Start writing LoanPay transaction tests

@dangell7 @shawnxie999 I have merged This merge caused massive merge conflicts which I resolved by basically rewrite signature checking, to maintain both the newly added functionality in #5060 (verification of signature of internal transactions) and also the newly added functionality in this PR (support for counterparty signature in The counterparty signature in this PR is EDIT: Github does not show consolidated diffs accurately; you will see it better in command line with |
