This tidies up the View interface and makes transaction
application a free function, with the removal of the
TransactionEngine class. A new class ApplyContext provides
all the state information needed to apply a Transactor. The
Transactor is refactored to perform all the processing
activities previously part of TransactionEngine.
The calculation of metadata from a MetaView is improved.
A new apply function performs all the steps for calculating
and inserting metadata into the tx map.
Transaction processing code path is passed a Config instead
of retrieving the global, and uses the Journal supplied in
the call to apply() consistently.
To support transaction processing and RPC operations, a
new POD type ViewInfo is added which consolidates static
information about open and closed ledgers, such as the ledger
sequence number or the closing times. Ledger and MetaView are
refactored to use this info.
The ViewInfo now contains the "open ledger" setting. The
tapOPEN_LEDGER ViewFlag is removed. The view property of
being an open ledger is obtained from the base or by using
the MetaView constructor which presents a closed ledger as
an open one.
View, MetaView:
* Fix missing includes
* Add apply free function
* Use Journal in TransactionEngine
* Use BasicView in TransactionEngine
* inline NetworkOPs::batchApply
* Add shallow_copy, open_ledger MetaView ctor tags
* Add ViewInfo with open flag, seq, close times
* Make parent_ a reference
* Tidy up ctor arguments and base_ name
* Remove tapOPEN_LEDGER
* add assert to MetaView::apply
* ViewInfo comment
* Throw, pass Journal in txInsert
* Add BasicView::txCount
TransactionEngine:
* Add apply
* Make TransactionEngine private
* Refactor MetaView::apply and apply()
* Rename to TxMeta
* Refactor treatment of metadata in MetaView, TransactionEngine
* Rename to ApplyContext
* Use ApplyContext& in Transactor
* Pass Config in ApplyContext
* Declare Transactor classes in headers
* Use view flags in Transactor
This shores up the View interface support for contextual
transaction processing by putting params in the View, and
provides support for replacing the open ledger with the
open MetaView.
Transaction metadata is now part of the View interface.
Stacked MetaViews correctly apply their transaction
metadata to the parent.
* Add lastCloseTime to View
* Add insertTx to View, implement in MetaView
* Add View::txExists for transaction checking
* Add Fees to View, cache fees in Ledger and MetaView
* Use ViewFlags in View
* Use tapENABLE_TESTING flag for features
* Use cached Fees in View
* Rename to ViewFlags
* Move FreezeHandling to View.h, remove ViewAPIBasics.h
* Remove BasicView::parent hack
* Remove calls to getLedger in Transactors
Classes implementing the consensus process on Ripple are cleaned
up in preparation for modularizations and compartmentalization.
Functions and state related to inter-round consensus are moved out
of NetworkOPs and into Consensus, where they are more effectively
isolated.
Some member functions are changed to free functions and some free
functions have their scope reduced to specific translation units.
* Track inter-round consensus state using new Consensus object
* Devirtualize interfaces
* Reduce NetworkOPs, Consensus and LedgerConsensus interfaces
* Add comments
All AccountID functionality is removed from RippleAddress and
replaced with free functions. The AccountID to string conversion
cache is factored out as an explicit type with an instance in
the Application object. New base58 conversion functions are used,
with no dependence on OpenSSL.
All types and free functions related to AccountID are consolidated
into one header file. Routines to operate on "tokens" are also
introduced and consolidated into a single header file.
A token one of the cryptographic primitives used in Ripple:
Secret Seed
Server Public Key
Server Secret Key
Account ID
Account Public Key
Account Private Key
and these deprecated primitives:
Account Family Seed
Account Family Generator
Member functions and free functions on Ledger and LedgerEntrySet are
rewritten in terms of new abstract interfaces `BasicView` and `View`,
representing the set of non-decomposable primitives necessary to read
and write state map items in a ledger, and to overlay a discardable
view onto a Ledger that can calculate metadata during transaction
processing. const-correctness is enforced through the parameter and
return types.
The MetaView now supports multi-level stacking: A MetaView can be
stacked on top of either a Ledger or another MetaView, up to any
number of levels.
The getSLEi member function is removed. The CachedView wrapper
replaces it, wrapping a View such that any function called with a
CachedView will go through the SLECache.
* Add BasicView, View, CachedView
* Rename LedgerEntrySet to MetaView
* Factor out free functions
* Consolidate free functions in ViewAPI
* Remove unused class members and free functions
This adds "require" functionality which allows invariants
to be checked after processing transactions using a simple,
terse interface. Also adds more comprehensive test coverage
for the framework itself, verifying that the more sophisticated
language constructs work in all ways.
All functions and classes have been split up into individual
files which may be included a-la carte, or accessed through
a single convenience header <ripple/test/jtx.h>
* Move, rename all sources
* Put everything in the jtx namespace
* Add sendmax funclet
* Rename funclet to paths
* Correctly set input issue and destination amount in path
* Conditionally invoke funclets using is_call_possible
* Add any() function means "any currency they will accept"
* Add None, none modifiers on amounts to mean "no amount"
* Add require conditions to JTx
* Add Env::require variadic condition checker
* Add le, rename some items for consistency
* Add require functors, balance, flags, nflags
* Add require functors lines, owners, offers, tickets
* Add ticket example of extending the system
* Add noripple modifier for funding accounst
* Add Env::st to parse Json into STTx
* Add tests to ensure correctness of fund()
* Add virtual Env member hooks
* Add Env::balance
* Add Env::seq
* Add PrettyAmount
* Add all container Account support
* IOU and XRP return PrettyAmount amounts
* IOUs print the issuer's name instead of base58
* Fix int and double conversions to XRP
* Fix autofill of Env::fund with noripple
This performs a deep refactor on the Ledger class and its supporting
classes, in preparation for the move to shared_ptr<SLE const> in
places where the SLE is immutable and we are currently using
shared_ptr<SLE>.
Member functions are converted to free functions, the SLECache is an
explicit parameter, one line convenience functions are removed to
streamline the interface. Some callers are changed to use <SLE const>
instead of <SLE>
SLECache:
* Moved to its own header file
RippleState:
* Remove unused functions
* Store the SLE as const
* Simplify callers
AccountState:
* Remove unused members
* Simplify existing members
Ledger:
* Replace writeBack with insert and update
* Remove unused functions
* Remove LedgerStateParams
* Move getLastFullLedger to Application
* add entryCacheI, exists, fetch, erase
* Use boost::optional where it makes sense
* Make member functions free functions
Free functions:
* fetch: cache-aware SLE retrieval
* forEachItem, forEachItemAfter
* (various)
This adds a suite of tools used to write unit tests. The Env provides
a context containing a ledger, and routines that assemble transactions
from JSON with optional "funclets" that add details in an exensible, terse
notation.
These routines replace existing code to compute SHA512-Half hashes.
The new code accumulates serialized data into a hashing context
instead of allocating a buffer, for improved performance.
* Inject dependencies, make functions free and levelize
* Add comments to document the intent behind the code
* Reduce class public interfaces
* Remove support for proposals without ledger hashes
A Validator Manifest allows validators to use a generated ed25519
secret key as a master key for generating new validator public/secret
key pairs. Using this mechanism, rippled instances trust the master
ed25519 public key instead of the now-ephemeral validator public key.
Through a new message and propagation scheme, this lets a validator
change its ephemeral public key without requiring that all rippled
instances on the network restart after maintaining the configuration
file.
* Consolidate constructors
* Use pointer/size instead of Serializer
* Factor out PendingSaves
* Make some members free functions
* Reduce size of constructor initializer lists
This commit provides support for 2-level multi-signing of
transactions. The ability is usually compiled out, since other
aspects of multi-signing are not yet complete.
Here are the missing parts:
o Full support for Tickets in transactions.
o Variable fees based on the number of signers,
o Multiple SignerLists with access control flags on accounts,
o Enable / disable operations based on access control flags,
o Enable / disable all of multi-signing based on an amendment,
o Integration tests, and
o Documentation.
Add support for the SignerListSet transaction as a step toward
multi-sign support.
As part of the SignerListSet implementation, add InnerObjectFormat
templates (similar to TxFormats and LedgerFormats) and enforce them
in STObject, STArray, and STParsedJSON.
* Remove the deprecated wallet_accounts command.
* Remove dead code for generator maps.
* Remove the help for the obsolete wallet_add and wallet_claim commands
(which have already been removed).
Credits made to any account during the processing of a payment are delayed until
the payment completes, enforcing a new invariant: liquidity for any paths
during a payment's execution may never increase. This eliminates the need for special
code to handle a variety of corner cases where consuming liquidity in one path
increases liquidity in others.
For large data sets the JOIN may not make forward progress in time.
This prevents the deletion of those entries in the database during
online delete. The number of such entries is very small compared to
the total size of the data anyway. A future version will address
this more thoroughly.
This introduces the STVar container, capable of holding any STBase-derived
class and implementing a "small string" optimization. STObject is changed
to store std::vector<STVar> instead of boost::ptr_vector<STBase>. This
eliminates a significant number of needless dynamic memory allocations and
deallocations during transaction processing when ledger entries are
deserialized. It comes at the expense of larger overall storage requirements
for STObject.
General RPC command that can retrieve objects in the account root.
* Add account objects integration test.
* Support tickets.
* Add removeElement in Json::Value
