The first few transactions are added to the open ledger at
the base fee (ie. 10 drops). Once enough transactions are
added, the required fee will jump dramatically. If additional
transactions are added, the fee will grow exponentially.
Transactions that don't have a high enough fee to be applied to
the ledger are added to the queue in order from highest fee to
lowest. Whenever a new ledger is accepted as validated, transactions
are first applied from the queue to the open ledger in fee order
until either all transactions are applied or the fee again jumps
too high for the remaining transactions.
Current implementation is restricted to one transaction in the
queue per account. Some groundwork has been laid to expand in
the future.
Note that this fee logic escalates independently of the load-based
fee logic (ie. LoadFeeTrack). Submitted transactions must meet
the load fee to be considered for the queue, and must meet both
fees to be put into open ledger.

* Add unit test for PendingSaves
This change causes each instance of Env to construct its own
isolated Application object for testing. Also included is
part of a framework to create multiple Application objects
in the same unit test and connect them together.
Eventually multisign will need to be enabled onto the network, at
which point compiling it in or out will no longer be an option.
In preparation, the compile guards are removed and multisign is
being enabled with a Feature.
You can locally enable a Feature using your config file. To
enable multisign with your config file add a section like this:
[features]
MultiSign
The exact spelling and capitalization of both "features" and
"MultiSign" is important. If you don't get those right multisign
will not be enabled.
There is a minor issue. The "sign_for" and "submit_multisigned"
RPC commands are only enabled if multisign is enabled. However
those commands are still shown in the help message even if
multisign is disabled. This is because the code that produces
the help message doesn't read the config file (where the Features
are kept). This problem will become irrelevant once multisign is
enabled onto the network.
With this changeset two-level multisigning is removed from the
codebase and replaced with single-level multisigning.
Additionally, SignerLists in the ledger are prepared for the
possibility of multiple SignerLists per account. This was done
by adding a defaulted 32-bit SignerListID to each SignerList.
The SignerListIndex calculation incorporates the SignerListID.
There are three known missing elements:
1. Multisigned transactions should require higher fees than
regular (single-signed) transaction. That's not yet
implemented.
2. It should be possible to disable the master key on an account
if that account is multisign enabled (has a signer list).
That's not yet implemented.
3. Documentation about multisigning needs to be improved.
Multisigning is still compiled out of the code base. To enable
multisigning for a stand-alone rippled, change the
RIPPLE_ENABLE_MULTI_SIGN macro (in BeastConfig.h) to "1" and
rebuild.
This commit also addresses:
o RIPD-912: Remove multisign APIs from STObject, and
o RIPD-944: Replace common_transactor with jtx at call sites.
This non-production config section allows features to be enabled
by listing their text descriptions, one line each, in the config
section titled "features".
NOTE: Feature names with leading or trailing whitespace, or
containing an equals sign ('=') are not supported.
This type alias provide cache-wrapping for Ledger objects.
Through the CachedLedger interface, access to the underlying
Ledger is permitted to allow for cases where the implementation
must perform Ledger specific activities. For example, building
a fetch pack from the contained SHAMap objects.
The CachingReadView is refactored:
* Renamed to CachedView
* Templated on Base, the base type
* base() returns a shared_ptr to the wrapped object
* Constructor requires a shared_ptr<Base>
The View hierarchy of classes is reorganized to include new
classes with member functions moved and renamed, to solve
defects in the original design:
OpenView accumulates raw state and tx changes and
can be applied to the base. ApplyView accumulates changes
for a single transaction, including metadata, and can be
applied to an OpenView. The Sandbox allows changes with
the option to apply or throw them out. The PaymentSandbox
provides a sandbox with account credit deferral.
Call sites are changed to use the class appropriate for
the task.
The OpenLedger class encapsulates the functionality of
maintaining the open ledger. It uses an OpenView with the
last closed ledger as its base. Routines are provided to
modify the open ledger to add new transactions, and to
accept a new last closed ledger. Business logic for
performing transaction retries is rewritten to fit this
framework and used in the implementation of accept.
When the RIPPLE_OPEN_LEDGER macro is set to 1 (BeastConfig.h),
the global Application OpenLedger singleton maintains
its open ledger in parallel by applying new transactions
and accepting new last closed ledgers. In the current
implementation this does not affect transaction processing
but logs any differences in the results as compared to
the original code.
Logging shows an occasional mismatch in what the OpenLedger
builds versus the original code, usually an OfferCreate
which gets a terINSUF_RESERVE instead of tesSUCCESS.
