FIXED: save ApiClient.translator
CHANGED: ApiClient now respects more resource annotations for building help messages (success and error responses)
CHANGED: Added more detailed annotations to BlocksResource
Some payments don't always initialize the recipient's
last reference, depending on whether the asset is QORA or not and
what type of transaction is being processed.
Calls to Payment.process/orphan now take boolean to indicate
whether recipient's last reference should always be initialized
regardless of asset.
("initialized" here means setting an initial last reference for
an account if the current value is null/empty/missing)
When matching orders to produce trades, it isn't enough to only
sort orders with best price first. Orders with the same price also
need to be further sorted by earliest order first. (This was
implicitly done in Qora v1). Added additional ORDER BY sub-clause
to achieve this and improved the corresponding table index too.
Converted a lot of logging from simplistic System.out/err.println
to Apache log4j2. Added several "trace"-level logging statements
to aid debugging which can be activated given appropriate
configuration in log4j2.properties.
With voting, detection of previous votes was broken during orphan
as previousOptionIndex was set to 0 instead of null when fetching
a VoteOnPollTransaction from the HSQLDB repository. This was due
to lack of null-checking - now fixed.
Corresponding changes made in IssueAsset and Message
transaction HSQLDB repository classes.
v1feeder now syncs up to block 99055. Block 99056 contains DeployAT.
Orphaning back to block 1 and then resync works without issue too.
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.
Added isFulfilled property to asset orders so completed orders can be filtered out.
Fixed migrate app by adding dummy name_reference values to UpdateNameTransactions and BuyNameTransactions INSERTS.
Fixed migrate app to use "poll_name" instead of "poll" for column name. Ditto "option_name" instead of "option".
Fixed some other incorrect column names in HSQLDBAssetRepository.
More unit tests but probably need yet more to cover complicated asset order matching with various divisibility settings.
Maybe fuzzing would help here somehow?
Settings class reworked to allow easier testing
Fix to Payment.orphan() where fee was being incorrectly subtracted instead of added
Added AssetRepository.fromAssetName(String): AssetData
Fixed deleting assets from HSQLDB repository due to broken column name in SQL.
Fixed saving IssueAssetTransactions in HSQLDB repository due to missing column binding.
More TransactionTests!
Fixed IssueAssetTransactions not being constructed with signature.
Fixed incorrect MessageTransactionData constructors.
Refactored various transactions to remove duplicate code.
e.g. in CancelOrderTransaction.process() use getCreator() instead of explicit repository call.
Added name_reference to BuyNameTransactions HSQLDB table.
Fixed incorrect SQL in HSQLDBMultiPaymentTransactionRepository.
More unit tests!
Fixed wrong data length in CancelOrderTransactionTransformer.
Fixed wrong data length in CreateOrderTransactionTransformer.
Fixed missing payment bytes in MultiPaymentTransactionTransformer.toBytes();
* Added more columns/properties to NameData to support updating timestamps, name sales
and reference to last transaction that changed Name (for orphaning support).
* Fixed serialization/deserialization bugs in MessageTransactions
* More tests
* Added simple genesis block timestamp setting to help testing
* Fixed setting account's last reference
* Moved some Poll constants from CreatePollTransaction to Poll
* HSQLDB: added TYPE PollOptionIndex
* HSQLDB: added previous_option_index to VoteOnPollTransactions table to help orphaning
* HSQLDB: renamed "poll" to "poll_name" in same table
* HSQLDB: PollOptions now has additional option_index column
* Improved TransactionTests to allow for different genesis block timestamps.
* Also added VoteOnPollTransaction test
Added CreatePollTransactionData constructor that doesn't need signature (for creating new transactions).
Added missing "published" timestamp support to PollData and Poll.
Removed extraneous timestamp test from Block.isValid.
Corrected inconsistent column names in poll-related tables in HSQLDBDatabaseUpdates.
HSQLDBRepository.checkedExecute(PreparedStatement) now takes extra Object... params
so that values can be bound to placeholders. Code moved from checkedExecute(String, Object...).
This fixes an issue with exists(String, String, Object...) where placeholders weren't having
any values bound to them. (Also removed "ORDER BY NULL" clause which isn't supported by HSQLDB).
HSQLDBVotingRepository method stubs fleshed out with real code.
TransactionTests rejigged but more work needed to test various transactions before/after their feature
release. e.g. testing create poll transactions before & after they supposedly went live.
Could do with a GenesisBlock constructor that takes a timestamp for testing purposes?
CreatePollTransactionTransformer now skips serializing a null signature,
in the same way PaymentTransactionTransformer does, to aid getBytesLessSignature().
This will probably need to be rolled out to all other transaction types.
* Replaced occurances of "this.repository.getResultSetBytes(resultSet.getBinaryStream(index))"
with "resultSet.getBytes(index)"
* Replaced corresponding preparedStatement.setBinaryStream() with preparedStatement.setBytes()
* Fixed migrate app so DB can be rebuilt using old v1 Qora client
* 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.
* 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.
* Created PaymentData transfer objects for (recipient, assetId, amount) tuples
* Created corresponding Payment class for validating, processing and orphaning payment(s)
* Modified OrderData to support isClosed for when an Order is cancelled so no more trades can occur
* Migrated CancelOrderTransactions and MultiPaymentTransactions
* Converted MessageTransactions, PaymentTransactions and TransferAssetTransactions to use new Payment class
Can't use PaymentTransformer in PaymentTransformer or TransferAssetTransformer due to serialization differences.
* Added AssetData transfer object
* Added IssueAssetTransactionData transfer object
* Reworked qora.assets.Asset into business layer object
* Reworked qora.transaction.IssueAssetTransaction into business layer object
* Added corresponding AssetRepository and support in TransactionRepository et al
* Fixed BlockChain in line with asset changes
* Some renaming inside GenesisTransaction to reflect use of transfer object, not business object
* Business transaction objects now take Repository param
* Moved HSQLDB transaction repositories into a sub-package
* Changed HSQLDBSaver.execute(Connection connection) to .execute(Repository repository) to fix visibility issues
and allow repository more control in the future if need be
* Changed from "return null" statements in HSQLDB repositories to throw DataException when an error occurs.
Better to throw than to silently return null?
* Added static version of PublicKeyAccount.verify() for when a repository-backed PublicKeyAccount is not needed
* Fixed getter/setter code template incorrectly producing "this.this.field = param"
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.
No need for database.DB class as the code is specific to HSQLDB so moved into relevant repository.hsqldb classes.
Top-level Repository instance (e.g. HSQLDBRepository) is used within subclasses, e.g. HSQLDBBlockRepository, so they
can share the same repository state, like underlying SQL Connection for easier transactional support.
HSQLDBRepository subclasses now call checkedExecute() on top-level repository instance, instead of passing Connection
to obsolete DB.checkedExecute.
No need for qora.block.BlockFactory any more as those methods are now in repository.
More work on Blocks and Transactions in general.
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.
