94decc753b perf: Move mutex to the partition level (#5486)
This change introduces two key optimizations:
* Mutex scope reduction: Limits the lock to individual partitions within `TaggedCache`, reducing contention.
* Decoupling: Removes the tight coupling between `LedgerHistory` and `TaggedCache`, improving modularity and testability.

Lock contention analysis based on eBPF showed significant improvements as a result of this change.

2a61aee562 Add Batch feature (XLS-56) (#5060)
- Specification: [XRPLF/XRPL-Standards 56](https://github.com/XRPLF/XRPL-Standards/blob/master/XLS-0056d-batch/README.md)
- Amendment: `Batch`
- Implements execution of multiple transactions within a single batch transaction with four execution modes: `tfAllOrNothing`, `tfOnlyOne`, `tfUntilFailure`, and `tfIndependent`.
- Enables atomic multi-party transactions where multiple accounts can participate in a single batch, with up to 8 inner transactions and 8 batch signers per batch transaction.
- Inner transactions use `tfInnerBatchTxn` flag with zero fees, no signature, and empty signing public key.
- Inner transactions are applied after the outer batch succeeds via the `applyBatchTransactions` function in apply.cpp.
- Network layer prevents relay of transactions with `tfInnerBatchTxn` flag - each peer applies inner transactions locally from the batch.
- Batch transactions are excluded from AccountDelegate permissions but inner transactions retain full delegation support.
- Metadata includes `ParentBatchID` linking inner transactions to their containing batch for traceability and auditing.
- Extended STTx with batch-specific signature verification methods and added protocol structures (`sfRawTransactions`, `sfBatchSigners`).

527e0c916f Lending protocol implementation (XLS-0066)
- 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

e514de76ed Add single asset vault (XLS-65d) (#5224)
- Specification: XRPLF/XRPL-Standards#239
- Amendment: `SingleAssetVault`
- Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange.
- A vault can be private or public.
- A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment.
- Shares can be exchanged back into asset with `VaultWithdraw`.
- Permissions on the asset in the vault are transitively applied on shares in the vault.
- Issuer of the asset in the vault can clawback with `VaultClawback`.
- Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.

2db2791805 Add PermissionDelegation feature (#5354)
This change implements the account permission delegation described in XLS-75d, see https://github.com/XRPLF/XRPL-Standards/pull/257.

* Introduces transaction-level and granular permissions that can be delegated to other accounts.
* Adds `DelegateSet` transaction to grant specified permissions to another account.
* Adds `ltDelegate` ledger object to maintain the permission list for delegating/delegated account pair.
* Adds an optional `Delegate` field in common fields, allowing a delegated account to send transactions on behalf of the delegating account within the granted permission scope. The `Account` field remains the delegating account; the `Delegate` field specifies the delegated account. The transaction is signed by the delegated account.

2406b28e64 refactor: Remove unused and add missing includes (#5293)
The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.

ea1fffeebf Enforce levelization in libxrpl with CMake (#5111)
Adds two CMake functions:

* add_module(library subdirectory): Declares an OBJECT "library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g. .build/tmp123, that contains just a symlink, e.g. .build/tmp123/basics, to the module's header directory, e.g. include/xrpl/basics, in the source directory, and putting .build/tmp123 (but not include/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake with target_link_libraries.
* target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).

Uses these functions to separate and explicitly link modules in libxrpl:

    Level 01: beast
    Level 02: basics
    Level 03: json, crypto
    Level 04: protocol
    Level 05: resource, server
