Some initial BTC cross-chain support. (Needs more work).
Unified timestamp for V2 switchover to block version 4,
applicable to several transaction types.
Qora-specific interface to CIYAM ATv2 library.
Beware: some areas still work-in-progress!
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.
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!
* 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 brokenmd160.java as command-line support for producing broken MD160 digests.
Transactions, and sub-classes, now use/store public key instead of Qora address.
(Qora address can be derived from public key and they take up about the same space in DB).
Loads more JavaDoc for lovely mouseover help in Eclipse IDE.
Crypto.verify() and Crypto.sign() moved into PublicKeyAccount and PrivateKeyAccount
as appropriate.
Fleshed out Block, added BlockTransactions support.
Added TODO comments as Eclipse helpfully lists these for later implementation.
Made loading-from-DB-constructors protected/private and also throw NoDataFoundException
if unable to load from DB. Public methods can call respective constructors, catch the above
exception and return null if they like. Load-from-DB-constructors are to allow sub-classes
to load some data from sub-tables and super-class to load from another table.
(See PaymentTransaction/Transaction for example). Using public methods allows similar argument
lists but with different names,
e.g. DBObject.fromSignature(Connection, byte[]) and DBObject.fromReference(Connection, byte[])
Saving into DB maybe still a bit untidy. Looking for a way to close-couple column names with
place-holder bind Objects.
Less of:
connection.prepareStatement("INSERT INTO table (column) VALUES (?)")
DB.bindInsertPlaceholders(PreparedStatement, Object...);
More like:
DB.insertUpdate(String tableName, SomeMagicCloseCoupledPairs...)
called like:
DB.insertUpdate("Cats", {"name", "Tiddles"}, {"age", 3});
Most SQL tables defined but only payment transactions actually implemented.
Maven support added.
Some code imported from 'old' Qora:
RIPEMD160 renamed as BrokenMD160 and deprecated.
whispersystem's Ed25519 implementation (to be replaced with bouncycastle).
Basic Account/PublicKeyAccount/PrivateKeyAccount code.
Some utils like Base58 and Pair.
To use:
Use maven to fetch dependencies.
Build project.
Fire up an old-gen Qora node.
Run src/test/update.java as a JUnit test to build DB structure.
Run src/test/migrate.java as a JUnit test to migrate old Qora blocks to DB.
You should now be able to run src/test/load.java and src/test/save.java
as JUnit tests demonstrating loading/saving Transactions from/to database.
This commit done while halfway through adding Block support!
