Also added Named/DaemonThreadFactory classes.
Network EPC now uses NamedThreadFactory for easier debugging.
Added settings field "networkPoWComputePoolSize", default 2, which
seems to work with both low-power ARM boards and high-power desktops.
If a node accepts a connection from an inbound peer
then remote peer will send RESPONSE first
and local node would previously change handshaking state
to COMPLETED while computing their own RESPONSE.
This meant that the local node would sometimes also start
sending post-handshake messages to the remote peer,
e.g. TRANSACTION_SIGNATURES.
Remote peer is only expecting a RESPONSE message, so would
close connection.
So we introduce an extra handshaking state "RESPONDING" for use
by local node while they compute RESPONSE in a separate thread.
Once the RESPONSE has been sent, local node moves to COMPLETED
state and called onHandshakeCompleted() as per usual.
Note that the code path when connecting outbound to a remote peer
is not changed, and the RESPONDING state is not used.
Also in this commit:
Network.onPeerReady now bypasses call to onMessage and instead
calls onHandshakingMessage() directly to avoid race condition
where peer's handshake status could change between
onPeerReady's caller and onMessage() calling peer.getHandshakeStatus()
NodeStatus contructor now fills in fields, which themselves are now 'final'.
NodeStatus also includes numberOfConnections and height as per systray.
AdminResource.status() unified with websocket version.
Incorrect column names when saving a group ban.
Missing column in LeaveGroupTransactions.
More stringent validity checks in group-kick, group-ban and remove-group-admin.
Added loads more tests to cover group actions.
Requires entries 'sslKeystorePathname' and 'sslKeystorePassword'
in settings.json.
With SSL enabled, API will auto-detect HTTP or HTTPs on the same port.
Included tools/build-keystore.sh to help build keystore from
Let's Encrypt certificates.
Renamed GET /blocks/minters to /blocks/signers
Renamed GET /blocks/minter/{address} to /blocks/signer/{address}
Changed corresponding repository methods and data classes.
Controller.onBlockMinted() now .onNewBlock(BlockData)
which saves having to fetch from repository.
Controller.onNewBlock also takes care of updating Controller's
cached chain tip, requesting SysTray refresh, broadcasting
new tip info to peers and notifying websockets.
BlockMinter and Controller.actuallySynchronize updated
to use unified .onNewBlock.
BlocksWebsocket also returns blocks on demand, given either
integer block height or base58 block signature.
Added support to return ApiError via websockets.
Unified Transaction.importAsUnconfirmed() and Controller.onNetworkTransactionMessage()
to both call Controller.onNewTransaction().
Modified Controller.onNewTransaction() to only send transaction signature to
other peers, instead of full transaction. Peers can request full transaction if they
don't have it.
Controller.onNewTransaction() also calls ChatNotifier, which in turn
notifies websocket handlers about new CHAT transactions.
Added jetty websocket dependency to pom.xml
Any reward leftover from ditributing to legacy QORA holders is reallocated to either:
founders if any online
or
account-level-based reward candidates, if no founders online
We should get pretty close to 100% block reward distribution, barring rounding artifacts.
More documentation and tests.
Removed BlockChain's founderShare as it is calculated in Block on a per-block basis instead.
Now we sum generic block reward + transaction fees before performing
distribution only once.
Added Map to collate account-balance changes during block reward
distribution so the final changes can be applied in one batch,
reducing DB load.
Some other optimizations like a faster ExpandedAccount.getShareBin().
Passes test EXCEPT RewardTests.testLegacyQoraReward(), pending decision
on how to reallocate 'unspent' block reward.
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.
