DB.rebuild() to shutdown and delete database, then rebuild it (schema only).
DB.callIdentity() to fetch value of IDENTITY column after an INSERT.
Added basic Asset class.
Added TODOs to Account.
BULK REFACTOR to rename "generation target" back to "generating balance" and
"generation signature" back to "generator signature" to ease compatibility with
old QORA for now. (Maybe change again in the future if we change from PoS).
Added support for Block's totalFees which is either loaded from DB
or recalculated as transactions are added to the block.
Also in Block:
* We can't assume generator's public key is the correct length
in case we encounter the GenesisAccount's special 8-byte public key. Fix applied to
Block's ResultSet-based constructor.
* Forgot to save "signature" column!
* Initial version of Block.process()
* Block constructor takes transactionsSignature too now
Added BlockChain startup/init/validation method to determine whether to (re)build blockchain.
Rebuilding blockchain involves rebuilding DB schema, processing GenesisBlock and adding QORA asset.
Added some initial GenesisTranaction.process() code: GenesisTransactions are saved but recipient's balance/reference not yet updated.
Fix incorrect placeholder bind value for "creation" timestamp in Transaction.save().
Moved incremental database schema updates out from "updates" unit test into DatabaseUpdates class.
All unit tests work at this point!
Too many calls needing Connection object in args when they're only
simple database reads. Even worse, some methods had database-less
counterparts with different outputs, e.g. toJSON().
Now Connections can be requested from the pool for general database
read scenarios. Code paths that might perform a multi-statement
database transaction still require a Connection arg passed around
as the database transaction are local to that Connection.
In light of above, added support for database opening, closing,
setting URL.
Fixed out of bounds array index bug in unknown-length version of DB.getResultSetBytes().
Fixed Block's lazy-instantiation of Transactions.
Implemented Block's isSignatureValid().
Fixed bug in Crypto.isValidAddress() which was using the wrong bytes.
Fix GenesisTransaction generic constructor calling super with PaymentTransaction type!
Fix GenesisTransaction signature constructor using wrong column indexes from ResultSet.
In Transaction, don't expect CREATOR_LENGTH bytes from database in case we're dealing
with a GenesisTransaction where the creator's public key is only 8 bytes long.
Improvements to unit tests, including changing migrate so it can be run repeatedly to do
incremental migrations.
PaymentTransaction now uses Account for recipient internally but maybe should extend that type change to constructor args.
GenesisBlock added also with signature test.
More javadocs.
