In some cases, a freshly cancelled reward-share could still have
an associated signed timestamp. Block.mint() failed to spot this
and used an incorrect "online account" index when building the
to-be-minted block.
Block.mint() now checks that AccountRepository.getRewardShareIndex()
doesn't return null, i.e. indicating that the associated reward-share
for that "online account" no longer exists.
In turn, AccountRepository.getRewardShareIndex() didn't fulfill its
contract of returning null when the passed public key wasn't present
in the repository. So this method has been corrected also.
AccountRepository.rewardShareExists(byte[] publicKey) : boolean added.
BlockMinter had another bug where it didn't check the return from
Block.remint() for null properly. This has been fixed.
BlockMinter now has additional logging, with cool-off to prevent log
spam, for situations where minting could not happen.
Unit test (DisagreementTests) added to cover cancelled reward-share
case above. BlockMinter testing support slightly modified to help.
Brought more into line with isValidUnconfirmed().
No need to update creator's lastReference under new last-ref scheme.
Correspondingly, no need to acquire blockchain lock or repository
shenanigans in getUnconfirmedTransactions() and getInvalidTransactions()
for the same reason.
getInvalidTransactions() seems to be unused and may well be cleaned up
in a future commit.
Change code of the form (assetId aspect not shown):
account.setConfirmedBalance( account.getConfirmedBalance(), amount )
to:
account.modifyAssetBalance( amount )
Also tidied "0 - value" to use unary negate: "- value"
Moved Asset.MULTIPLIER, etc. to Amounts class.
Had to reintroduce BigInteger for asset trading code.
Various helper methods added to Amounts class.
Payment.process/orphan no longer needs unused transaction
signature or reference.
Added post block process/orphan tidying, which currently deletes zero account balances to satisfy post-orphan checks in unit tests.
Fix for possible bug when orphaning TRANSFER_PRIVS.
Added RewardSharePercentTypeAdapter like AmountTypeAdapter.
Replaced a whole load of JAXB-special getters with type-adapters.
Tests looking good!
Now possible thanks to removing Qora v1 support.
Maximum asset quantities now unified to 10_000_000_000,
to 8 decimal places, removing prior 10 billion billion
indivisible maximum.
All values can now fit into a 64bit long.
(Except maybe when processing asset trades).
Added a general-use JAXB AmountTypeAdapter for converting
amounts to/from String/long.
Asset trading engine split into more methods for easier
readability.
Switched to using FIXED founder block reward distribution code,
ready for launch.
In HSQLDBDatabaseUpdates,
QortalAmount changed from DECIMAL(27, 0) to BIGINT
RewardSharePercent added to replace DECIMAL(5,2) with INT
Ripped out unused Transaction.isInvolved and Transaction.getAmount
in all subclasses.
Changed
Transaction.getRecipientAccounts() : List<Account>
to
Transaction.getRecipientAddresses() : List<String>
as only addresses are ever used.
Corrected returned values for above getRecipientAddresses() for
some transaction subclasses.
Added some account caching to some transactions to reduce repeated
loads during validation and then processing.
Transaction transformers:
Changed serialization of asset amounts from using 12 bytes to
now standard 8 byte long.
Updated transaction 'layouts' to reflect new sizes.
RewardShareTransactionTransformer still uses 8byte long to represent
reward share percent.
Updated some unit tests - more work needed!
CHAT transactions don't ever get included into a block.
They use a memory-intensive proof-of-work instead of a fee.
Reference field isn't checked but must be present.
Recipient is optional.
isText/isEncrypted as per MESSAGE, basically indicative flags only.
Some API support.
Memory PoW takes roughly 800ms on Ryzen 3600, maybe 2400ms on QORTector?
As this changes how lastReferences are checked and updated,
this is not suitable for rolling into current chain without a
"feature trigger", or chain restart!
Added unit tests.
NullAccount has 'empty' public key (32 bytes of zeros) compared
with GenesisAccount's vague sometimes 8 bytes, sometimes 32 bytes
public key.
NullAccount has static public key and address, plus overridden
methods to speed up pointless calls like verify().
Genesis Block also tidied up, dropping old Qora v1 compatibility
and using proper block signature and public key to generate
minter's block signature.
Genesis Block transaction processing also simplified, with no need
to access repository to handle fake references, due to new
last-reference code (which will need to be merged).
Dropped support for old, broken RMD160 code.
Qortal is never going to continue off the old Qora blockchain,
so removed all code regarding compatibility.
Removals include:
* various blockchain "feature triggers"
* special Qora-only broken code for various transaction signatures
* "old" asset pricing / trading
* pre-group txGroupId field in transactions
* compatibility unit tests
Possibly safe for roll-out on pre-genesis blockchain?
Tidied up duplicated cross-chain API code that
fetched Qortal AT info.
Added Bitcoin-related cross-chain API calls
for building, checking, refunding and redeeming
P2SH.
Added new Bitcoin-related API error codes.
Controller now starts up, and shuts down, bitcoinj.
Speed-up in BTC class so bitcoinj doesn't have
to throw away all peers and rediscover & reconnect
to them with every chain-related call.
Added API calls to aid Qortal-side of cross-chain trading.
POST /crosschain/build - for building Qortal AT
POST /crosschain/tradeoffer/recipient - for sending trade partner/recipient to AT
POST /crosschain/tradeoffer/secret - for sending secret to AT
DELETE /crosschain/tradeoffer - for cancelling AT
More fixes regarding Blocks processing/orphaning ATs.
More fixes regarding sending/receiving blocks containing AT data.
AT-related fix to genesis block.
Improved cross-chain trading AT code, removing offer-mode timeout
and replacing that with allowing AT creator to cancel offer/end AT
by sending AT the creator's own address as trade partner/recipient.
After all, they're not going to trade with themselves.
Added assertion to check BTCACCT.CODE_BYTES_HASH matches compiled code hash.
Added cross-chain AT's 'mode' for easier diagnosis, either OFFER or TRADE.
We can't use AT's signature to generate AT address because address is needed
before DEPLOY_AT transaction is signed. So we use a hash of signature-less
transaction bytes.
Corresponding changes to tests.
Reworked the cross-chain trading AT so it is now 2-stage:
stage 1: 'offer' mode
waiting for message from creator containing trade partner's address
stage 2: 'trade' mode
waiting for message from trade partner containing secret
Adjusted unit tests to cover above.
Changed QortalATAPI.putCreatorAddressIntoB from storing
creator's public key to actually storing creator's address.
Refactored BTCACCT.AtConstants to CrossChainTradeData.
Now we also store hash of AT's code bytes in DB so we can look up
ATs by what they do. Affects ATData class, ATRepository, etc.
Added "Automated Transactions" and "Cross-Chain" API sections.
New API call GET /at/byfunction/{codehash} for looking up ATs
by what they do, based on hash of their code bytes.
New API call GET /at/{ataddress} for fetching info for specific AT.
New API call GET /at/{ataddress}/data for fetch an AT's data segment.
Mostly for diagnosis of AT's current state.
New API call POST /at for building a raw, unsigned DEPLOY_AT transaction.
New API call GET /crosschain/tradeoffers for finding open BTC-QORT trading ATs.
