Before:
0-fee self-share REWARD_SHARE when there is an existing self-share would result in
INSUFFICIENT_FEE from isFeeValid()
After:
isFeeValid() returns OK for above, but isValid() returns SELF_SHARE_EXISTS.
In addition, a transaction that tries to modify existing self-share, even with fee,
also returns SELF_SHARE_EXISTS.
Improved tests to double check.
NOTE: first startup after this commit can take a while due to building index!
SQL statement "DELETE FROM HistoricAccountBalances WHERE height >= ?" required
a full table scan and so was very slow on VMs/routers. This statement used by
HSQLDBAccountRepository.deleteBalancesFromHeight(), itself called during
Block.orphan().
Symptoms particularly evident during shutdown where above statement could take
upwards of 15 minutes on single-CPU, small-memory VMs!
Statement wasn't noticed before as slow-query checking wasn't involved.
Slow-query checking now applies to HSQLDBRepository.delete() and
HSQLDBRepository.exists() calls.
Added test for correct HSQLDB interrupt handling.
Fixed some typos.
Blockchain configs will need "v2Timestamp" feature trigger renaming to "qortalTimestamp"!
Due to Controller.VERSION_PREFIX changing, peer-to-peer protocol version detection has
been changed. Was previous a substring match, now we test peers's buildTimestamp is at
least Peer.V2_PROTOCOL_TIMESTAMP_THRESHOLD. Changes in Peer.java.
Also added comment and throw() to QortalATAPI.getNextTransactionTimestamp()
as this needs given the change to Qortal's block timestamps from legacy Qora.
Changes to HSQLDB data types, e.g. QoraAddress to QortalAddress, means existing
database will need to be thrown away after this commit!
Seems to produce fat JARs with the same MD5 after repeated runs of:
mvn clean package
Needs testing on other platforms, hence this commit.
Also trimmed some unneeded included JAR libraries from pom.xml,
e.g. netty, async-http-client,
and the *.js.map files from Swagger-UI, which seems to reduce
output JAR size from about 51MB to about 44MB.
Converted AccountData's initialLevel to blocksMintedAdjustment.
Corresponding changes to AccountLevelTransaction so that level
set in genesis block is converted to blocksMintedAdjustment,
via cumulativeBlocksByLevel.
Ditto changes to HSQLDBAccountRepository, HSQLDBDatabaseUpdates,
[HSQLDB]TransactionRepository, etc.
Changes to API call POST /admin/mintingaccounts to check passed
reward-share private key maps to a reward-share with minting
account that still has privilege to mint. It's possible for
a TRANSFER_PRIVS transaction to transfer away minting privileges
from a minting account referenced by in a reward-share.
Change to RewardShareTransaction to allow users to cancel a
reward-share even if minting-account component no longer has
minting privs. This should allow users to clean up more after
a privs transfer.
Re-order processing/orphaning in Block.process()/Block.orphan()
to be more consistent and also to take in account changes that
might have been caused by TRANSFER_PRIVS transactions which affect
who might actually receive block rewards/tx fees.
Founders now gain blocksMinted & levels as part of minting blocks.
(Needed to make TRANSFER_PRIVS from a founder account to work).
BlockMinter now has added checks to make sure that the reward-shares
it might use to mint blocks still have valid minting-accounts.
i.e. that the minting-account component of reward-share hasn't had
minting privs transferred away by TRANSFER_PRIVS tx.
Controller now rejects online-accounts from peers that no longer
have minting privs (e.g. transferred away by TRANSFER_PRIVS)
Corresponding, Controller no longer SENDS online-accounts that no
longer have minting privs to other peers.
Added some tests - more tests needed, e.g. for multiple transfers
into the same account, or a test for minting post transfer for both
sender & recipient.
Previously it was possible broadcast an auto-update tx that was
created by a 'dev' group admin.
Now the auto-update tx must be created by a 'dev' group non-admin/owner
and hence require group approval before it takes effect.
To this end, a new TransactionRepository.getLatestAutoUpdateTransaction()
method has been added to simplify finding the latest matching, approved
auto-update transaction.
Corresponding changes also made to AutoUpdate.run()
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.
