These changes are for allowing devices to be shipped with an interim blockchain config & genesis block, running with "main-net" settings, prior to launch.
At launch, an "auto-update" will be broadcast to replace blockchain config & genesis block with the final, launch version.
When updated nodes restart (immediately after auto-update) they should notice their existing genesis blocks are invalid and hence wipe their blockchains,
effectively starting the final, launch blockchain.
To this end, genesis block signatures have been changed to better incorporate values that are likely to change at launch, e.g. block timestamp and transaction data.
Added Crypto.dupDigest(), which is effectively Bytes.concat(digest(msg), digest(msg)).
No need for HSQLDB repository to backup, or wipe, non-existent files for "in-memory" databases!
New interim blockchain config/genesis block.
**NOTE** These changes are being committed but require testing. However the auto-update suite requires a pushed commit in order to build an update file!
Now reward-shares with zero percent are valid, to allow the 'recipient' party to gain
"number of minted blocks" but no actual block reward.
Correspondly, the special zero share used to cancel reward-shares has been changed to
be any negative value.
Block rewards, founder 'leftovers': if founder is minter account in any online
reward shares, then the per-founder-share is spread across their online reward-shares,
otherwise it's simply/wholy given to that founder.
Created a new DB table to hold "next block height", updated via triggers on Blocks.
This is so various sub-queries can simply read the next-block-height value instead
of complex IFNULL(MAX(height),0)+1 or SELECT height FROM Blocks ORDER BY height DESC.
Prior code was also broken in edge cases, e.g. no genesis block, or ran slow.
Added tests to cover above.
Deleted BTC tests as they're obsolete.
Added/improved other tests.
*** WARNING ***
Possible block reward bug in this commit. Further investigation needed.
Reverted AccountBalances back to height-less form.
Added HistoricAccountBalances table that is populated via trigger on AccountBalances.
This saves work when performing common requests for latest/confirmed balances,
shunting the extra work to when requesting height-related account balances.
Unified API call GET /addresses/balance/{address} by having address/assetId/height as
query params.
Simpler call for fetching legacy QORA holders during block rewarding.
Improved SQL for fetching asset balances, in all conditions,
e.g. with/without filtering addresses, with/without filtering assetIds,
etc.
Unit test for above to make sure query execution is fast enough.
(At one point, some SQL query was taking 6 seconds!)
Added optional 'height' Integer to AccountBalanceData, but this
is not populated/used very often.
HSQLDBAccountRepository.save(AccountBalanceData) now checks zero balance saves
to see if the row can be deleted instead. This fixes a lot of unhappy tests
that complain that there are residual account balance rows left after
post-test orphaning back to genesis block.
Yet more tests.
Removed very old 'TransactionTests' which are mostly covered in more specific tests elsewhere.
Added cancel-sell-name test from above.
Fixed AssetsApiTests to check for QORT not QORA!
Changed hard-coded assetIDs in test.common.AssetUtils in light of new LEGACY_QORA & QORT_FROM_QORA genesis assets.
Some test blockchain config changes.
Also:
RewardShareKeys app now supports only one arg (minter private key)
in self-reward-share mode, where recipient public key is derived
from minter private key.
Added methods to Account for returning 'effective' minting level
where minting level for founders is read from blockchain config.
(Or returns zero if unable to mint).
Changed two Block constructors into static methods that return
a new Block as there was way too much work being done to really
be called a constructor, especially with all the opportunities
to throw an exception too.
Main blockchain config updated to reflect near-launch version.
Added/changed blockchain weight tests to check block winning
based on higher account levels.
Added Transaction.isFeeValid() to allow transaction subclasses to override and allow zero fees, etc.
Added tests to cover self-reward-shares, including zero fee scenario.
Set 'dilbert' test account to level 8 in test genesis block.
Removed leftover mention of "previous_level" from HSQLDBAccountLevelTransactions,
and AccountLevelTransactionData. (Previous level makes no sense as ACCOUNT_LEVEL
transactions are genesis-block only).
Fixed some incorrect uses of PrivateKeyAccount.getSharedSecret() to
PrivateKeyAccount.getRewardSharePrivateKey() in tests.
Unified terminology from block "generator", "forger", etc. to "minter"
Unified terminology "proxy forger" to "reward share" as it was
incorrect, or at least highly ambiguous, which account had which role.
AccountRepository.findRewardShares() has different arg order!
Account.canMint() now returns true if account has 'founder' flag set.
Added Account.canRewardShare() which returns whether acocunt can create
a reward-share (e.g. level 5+ or founder).
Fixed HSQLDBAssetRepository.getAllAssets() which had incorrect
resultSet column indexes.
Removed old traces of EnableForging transaction.
ACCOUNT_LEVEL and ACCOUNT_FLAGS (genesis-block-only transaction types)
now set target account's last-reference. This is allow later REWARD_SHARE
transactions in genesis block and post-genesis transactions by that account.
REWARD_SHARE transactions are now FREE, but only if minter is also recipient.
If a self-reward-share already exists, then unless share-percent is zero (to
terminate reward-share), any subsequent self-reward-share is invalid.
Updated SysTray i18n properties file.
BlockChain config file requires 'minAccountLevelToRewardShare' and optional
'minAccountLevelToMint'.
Added potential, but currently unused, memory-hard PoW algorithm.
Fixed/removed/disabled some unit tests.
BlockMinter.generateTestingBlock asks Controller to pretend mintingAccount is 'online'.
More testing needed!
Rename Asset.QORA to Asset.QORT so we can also have Asset.LEGACY_QORA
as another hard-coded asset.
Add "is unspendable" aspect to assets where only the asset owner can
transfer/pay asset to other people. Asset trading is barred regardless,
as is use of asset for ATs.
Added "initial level" to account data in preparation for accounts levelling
up from generating blocks.
Added distribution/removal of block reward based on legacy-QORA held.
Removed "previous level" from ACCOUNT_LEVEL transactions as they're
only ever valid in genesis block and so previous level is never needed.
Synchronizer incorrectly tried to compare chain weights in the case
where we had no extra blocks after common block, and thus no blocks
to actually compare.
During chain compare, when more block summaries are needed from peer,
the block signature sent to peer wasn't updated from the last batch
and so the same common block signature was sent. This caused the
code to incorrectly bail out with
"Peer respond with invalid block summary" error as the block heights
didn't match.
Post chain-compare/orphan (if any), and when fetching block signatures,
the code referenced peerBlockSummaries where it should have been
referencing peerBlockSignatures instead. This caused to code to incorrectly
bail out with the "Peer failed to respond with more block signatures..."
error.
Updated pom.xml.
Updated dependencies, including various minor code mods, esp. bitcoin-related.
Starts up and talks to Java 8 nodes!
Dev environment should be at least Eclipse 4.11 with m2e 1.9.1+
