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
HSQLDB v2.4.0 had some issue with non-padded, case-insensitive string comparisons.
This is fixed in svn r5836-ish of HSQLDB but yet to be pushed out to new HSQLDB release.
So this commit includes hsqldb-r5836.jar and modified pom.xml/.classpath for now.
No need for duplicate, hidden creatorPublicKey in CancelOrderTransactionData,
CreateOrderTransactionData and CreatePollTransactionData.
Various changes to use more try-with-resources, especially with JDBC objects like
Connection, Statement, PreparedStatement, ResultSet.
Added loads of missing @Override annotations.
Fixed bug in Asset exchange order matching where the matching logic loop
would incorrectly adjust temporary amount fulfilled
by the "want" asset amount (in matchedAmount)
instead of the "have" asset amount (in tradePrice).
Disabled check for duplicate asset name in IssueAssetTransactions for old v1 transactions.
In HSQLDB repository we now use ResultSet.getTimestamp(index, UTC-calendar) to make sure we
only store/fetch UTC timestamps. The UTC-calendar is made using static final TimeZone called
HSQLDBRepository.UTC.
To keep asset IDs in line with v1, Assets.asset_id values are generated on-the-fly in HSQLDB
using a "before insert" trigger on Assets table. Corresponding code
calling HSQLDBRepository.callIdentity() replaced with SELECT statement instead.
Moved most of the HSQLDB connection properties from the connection URL to explicit code in
HSQLDBRepositoryFactory.
Fixed incorrect 'amount' lengths in PaymentTransformer, as used by MultiPayment and Arbitrary
transaction types.
Added support for mangled arbitrary transaction bytes when generating/verifying a v1 transaction signature.
In v1 Arbitrary transactions, bytes-for-signing are lost prior to final payment (but only if there are any payments).
Added corresponding code for multi-payment transactions in the same vein.
NOTE: requires HSQLDB built from svn rev 5836 or later
Fixed BuyNameTransactionData constructors not picking up nameReference.
Added new "orphan" tool to regress blockchain back to specified block.
Added new Block constructor for when receiving a block from the network.
Fixed Block generatingBalance/forging code to be compliant with v1.
Added logging of transactions that fail validation during block validation.
Fixed buyer/seller balances not being updated during name purchase.
Generally replace BigDecimal.compareTo expressions with "<operator> 0" form.
e.g. instead of someBigDecimal.compareTo(anotherBigDecimal) == 1
we now have someBigDecimal.compareTo(anotherBigDecimal) > 0
Fix amounts involved in BuyNameTransactions.
Renamed Transaction.calcSignature to .sign
Refactored Transaction.toBytesLessSignature to TransactionTransformer.toBytesForSigning,
which itself calls subclass' toBytesForSigningImpl,
which might override Transaction.toBytesForSigningImpl when special v1 mangling is required.
Corrected more cases of NTP.getTime in transaction processing
which should really be transaction's timestmap instead.
Fixed HSQLDB-related issue where strings were padded with spaces during comparison.
Some column types no longer case-insensitive as that mode of comparison
is done during transaction validation.
Added missing option_index column to CreatePollTransactionOptions which was causing
out-of-order options during fetching from repository and hence signature failures.
Added unit tests for v1-special mangled transaction signature checking.
Removed checks for remaining bytes to ByteBuffer in various transaction transformers'
fromByteBuffer() methods as the buffer underflow exception is now caught in
TransactionTransformer.fromBytes.
Corrected byte-related transformations of CreatePollTransactions that were missing
voter counts (albeit always zero).
Corrected byte-related transformations of IssueAssetTransactions that were missing
duplicate signature/reference (v1-special).
Added "txhex" tool to output transaction in hex form, given base58 tx signature.
Added "v1feeder" tool to fetch blocks from v1 node and process them.
* Moved Asset issue/deissue code from IssueAssetTransaction to Asset business object.
* Added more constructors for Asset using IssueAssetTransactionData or assetId.
* Moved some constants from transaction transfers to business objects (e.g. IssueAssetTransaction)
(They might now make more sense being in Asset)
* Changed some transaction isValid() checks to use transaction's timestamp instead of NTP.getTime()
* New VotingRepository - as yet unimplemented
Really need to rewrite "migrate" and add a ton of unit tests.
