No more bitcoinj peer-group stalls, or slow startups,
or downloading tons of block headers, or checkpoint files.
Now we use ElectrumX protocol to query info from random servers.
Also:
BTC.hash160 callers now use Crypto.hash160 instead.
Added BitTwiddling.fromLEBytes() returns int.
Unit tests seem OK, but needs complete testnet ACCT walkthrough.
Group owner now derived from CREATE_GROUP transaction creator's public key.
Added 'reduced' group name to GroupData, with corresponding change to DB.
Renamed GroupData.getIsOpen() to simply isOpen().
Tidied up CreateGroupTransactionData, adding 'reduced' group name.
Renamed getIsOpen() to simply isOpen().
Added code to generated reduced group name when building genesis block.
Added Group.MIN_NAME_SIZE of 3.
DB tables changed to add reduced_group_name where appropriate,
removing owner where necessary.
Added GroupRepository.reducedGroupNameExists(String).
Fixed up test blockchain configs in src/test/resources/test-chain-v2*.json.
This allows on-chain messages to a group, including NO_GROUP / groupID zero.
No-recipient messages cannot have an amount - where would it go?
Changed MESSAGE serialization layout to add boolean indicating
whether recipient is present.
Changed MESSAGE serialization layout so assetID is after amount,
and only present if amount is non-zero.
Changed DB table structures to cover above.
Added unit tests to cover above.
Owner now derived from issuer's public key.
Maximum asset name length reduced to 40 characters.
Repository table changes.
"owner" removed from test blockchain configs and "issuerPublicKey" used instead
where applicable.
Some getters in the form of "getIs___()" renamed to simply "is____()".
Changes include:
* Allowing renaming
* Tracking last-updated timestamps
* More stringent Unicode processing
* Way more unit tests
* Max name length reduction to 40 chars
Note: HSQLDB repository table changes
Controller no longer starts up BTC support during main startup.
This does mean that BTC startup is deferred until first BTC-related
action, and that the first BTC-related action will take much longer
to complete.
Added tests to cover startup/shutdown.
This also fixes splash logo stuck on-screen and broken Controller
shutdown when using REGTEST bitcoin network AND there is no
local regtest bitcoin server running.
REGISTER_NAME has an "owner" field which can be different from the actual
registrant (transaction creator's public key, used for signing transaction).
This allowed people to register names to be owned by someone else, thus breaking
the whole "one name per account" aspect.
So now "owner" is removed from REGISTER_NAME, and the actual owner address is
derived from transaction creator's public key, as you would expect.
Similarly, UPDATE_NAME has a corresponding "newOwner" field which has been removed.
In addition, UPDATE_NAME now allows users to change their registered name using a new
"newName" field.
Various changes made to DB, Name class, etc. to accomodate above, along with some minor
bug-fixes and comment improvements/corrections.
Needs new unit tests to cover both new functionality and old!
Collated all development changes to DB so now we build
initial DB structure directly with final layout.
i.e. no ALTER TABLE, etc.
Reordered HSQLDB 'CREATE TYPE' statements into alphabetical order
for easier maintainability.
Replaced TIMESTAMP WITH TIME ZONE with simple BIGINT ("EpochMillis").
Timezone conversion is now a presentation task, rather than having
pretty values in database.
Removed associated conversion methods, like toOffsetDateTime(),
fromOffsetDateTime() and getZonedTimestampMilli().
Renamed some DB columns to make them more obviously timestamps, like:
Names.registered is now Names.registered_when.
Removed IFNULL(balance, 0) from HSQLDBAccountRepository as balances
are never null, or actually never 0 either.
Added more tests to increase API call, and hence repository, coverage.
Removed unused "milestone block" from Transactions.
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.
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.
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.
We require AT v1.3.4 now!
Updated AT-related logging.
Added "isInitial" flag to AT state data so that state data created at
deployment is not added to serialized block data.
Updated BTC-QORT AT code and tests to cover various scenarios.
Added missing 'testNtpOffset' to various test versions of 'settings.json'.
Added missing 'ciyamAtSettings' to various test blockchain configs.
Loads of AT-related additions/fixes/etc. to core code, e.g Block
Requires fix in CIYAM AT v1.3.2
New version of Qortal cross-trade AT code.
Change how Qortal addresses are managed in QortalATAPI from using
base58 strings (that are too long) to using hex form (25 bytes)
as they need to fix into 32 byte A/B register.
Generate AT addresses using DeployAtTransaction's signature instead
of convoluted hash of AT data like name, description, etc.
Add startTime as arg to GetTransaction test app.
Add missing fields (name, description, ATType, tags) to DeployAT test app.
Bump CIYAM AT requirement to v1.3
Remove multi-blockchain AT aspect for now (BlockchainAPI).
For PUT_PREVIOUS_BLOCK_HASH_INTO_A we no longer use SHA256 to condense 64-byte block signature into 32 bytes.
Now we put block height into A1 and SHA192 of signature into A2 through A4.
This allows possible future lookup of block data using "block hash", with verification that it is the same block.
Some AT functions use "address in B" but sometimes we populate B with account's public key instead.
So the method "getAccountFromB" is smart and checks for an actual, textual address in B starting with 'Q', otherwise assumes B contains public key.
The Settings field "useBitcoinTestNet" (boolean) now replaced with "bitcoinNet" (String) with possible values MAIN (default), TEST3, REGTEST.
This allows for more varied development/testing scenarios.
Use correct Bitcoin nSequence value 0xFFFFFFFE for P2SH, i.e. enable locktime, disable RBF.
Roll REGTEST checkpoints file generator into main BTC class.
Yet another rewrite of Bitcoin P2SH scripts for BTC-QORT cross-chain trading.
Added associated test classes BuildP2SH, CheckP2SH, DeployAT (unfinished).
Streamlined BTC class and switched to memory block store.
Split BTCACCTTests into BTCACCT utility class and (so far)
three stand-alone apps: Initiate1, Refund2 and Respond2
Moved some Qortal-specific CIYAM AT constants into blockchain config.
Removed redundant BTCTests
Bump bitcoinj to 0.15.5 for fixes.
lockTime is int (seconds since epoch), not long (ms since epoch).
Improve output of Initiate1.
Added (most of) Respond2.
