Now using ATv2 dated 20181101172102
ATData now uses byte[] creatorPublicKey instead of String creator.
TransactionData now has hashCode() and equals() methods,
which is needed for new Transaction Comparator,
used to sort transactions within a block,
AT-first, then timestamp, then signature.
AT-Transactions generate their own signatures using SHA2-256 of serialized data.
Arbitrary Transactions try to clean up their files when orphaned.
Deploy AT Transactions now check creation bytes (even for old v1 ATs).
Deprecated Transaction.getBlock() as it doesn't seem used
and would be better to simply have getHeight() rather than
a method that 'knows too much' about Blocks/BlockData.
Corresponding TransactionRepository.getBlockDataFromSignature()
also deprecated.
Loads more comments.
Tidied up some SQL: mainly correcting case,
moving PRIMARY KEY clauses to end of CREATE TABLE,
removing unnecessary columns from indexes.
Added "type" column to TransactionCreatorIndex so users can find
their transactions and optionally filter by type.
In BlockTransactions table, transaction_signature is now UNIQUE
as a transaction cannot be included in more than one block.
Various AT-related HSQLDB table and index changes.
ArbitraryTransactions transformer fixed to always return a list of payments,
even if empty. (Previously could return null which broke things).
Added simplistic block generator.
NOTE: unit tests broken due to pending upgrade to JUnit 5
* Add implementation for Account.getBalance(assetId, numberOfConfirmations)
* Added orphan() code to Block (CIYAM AT not yet supported)
* Added getOrder() 'navigation' method to CreateOrderTransaction
* Added missing transaction-type cases to various switches in Transaction, transformers, repositories, etc.
* Various repository delete() methods added
* Added save/delete support for transaction types that include payments, like multipayment and arbitrary
* Changed "recipient" in HSQLDB SharedTransactionPayments from QoraPublicKey to QoraAddress
* Code added for calculating an account's generating balance. (CIYAM AT support yet to be added).
* Added associated code in Block for calculating next block's timestamp, generating balance, base target, etc.
* ValidationResult enum added to Block, mostly to aid debugging.
* Block.isValid() now returns ValidationResult instead of boolean.
* Block.isValid() now has added proof-of-stake tests.
* Some blockchain-related constants, like feature release heights/timestamps, moved from Block to BlockChain.
* Added better Block constructor for use when creating a new block.
* Added helpful 'navigation' methods to Block to get to block's parent (or child).
* Changed visibility of block's individual signature calculators to protected, in favour of public sign() method.
* Added asset existence check to Payment.isValid.
* All current transaction objects (qora.transaction.*) now have private subclassed transaction variable to save multiple casts in various methods.
* Also added to above:
* isInvolved(Account) : boolean
* getRecipients() : List<Account>
* getAmount(Account) : BigDecimal
* Added BlockRepository.getLastBlock() to fetch highest block in blockchain.
* Added diagnostics to HSQLDBRepository.close() to alert if there are any uncommitted changes during closure.
(Currently under suspicion due to possible HSQLDB bug!)
* Old "TransactionTests" renamed to "SerializationTests" as that's what they really are.
* New "TransactionTests" added to test processing of transactions. (Currently only a PaymentTransaction).
* PaymentTransformer.toBytes() detects and skips null signature. This was causing issues with Transaction.toBytesLessSignature().
Needs rolling out to other transaction types if acceptable.
Moved more repository-like methods from qora.* classes to repository.
Removed qora.block.BlockTransaction as it's pretty much internal to the HSQLDB repository.
Fixing qora.account.*
Fixing genesis-related classes: block, account, transaction...
Rolled BlockTransactionRepository into BlockRepository.
Added AccountRepository for general account info and account balances.
BlockTransformer now takes Block as param instead of BlockData as it needs Block's transactions.
Still converting to repository layout.
This commit is just in case my dev computer blows up and also for interim code review.
Removed data.block.BlockData as an interface (with data.block.Block as implementation) for now.
