Now uses several NTP servers to determine mean offset from
system clock to internet time.
If abs(offset) > 500ms or NTP service not running then
user is 'nagged' via system tray pop-up notification
with instructions on how to fix.
Also improved system tray translations!
Reworked networking execute-produce-consume threading.
Some networking task were wrongly performed during 'produce' phase,
and some producing was happening in 'consume' phase (also corrected).
Peer connection tasks are rate-limited to 1 per second to reduce CPU thrashing.
Show P2P listen port in logs on startup.
Tests for general purpose ExecuteProduceConsume class to cover both
random task scenario and mass-ping scenario.
Included unit test to cover change.
Modified test blockchain config "test-chain-v2.json" to add maxProxyRelationships.
Added comments to some proxy-related methods in AccountRepository class.
Added transaction [de]serialization test, along with corresponding random transaction generators.
Minor typo fix in Transaction.
Minor clarification in MessageTransactionTransformer.
Added debugging to Account.
Bumped version
Controller no longer uses block height to determine whether to sync
but now uses peer's latest block's timestamp and signature.
Also BlockGenerator checks whether it's generating in isolation using
the same peer info (latest block timestamp and signature).
Added API call POST /admin/forcesync peer-address to help get wayward
nodes back on track.
Unified code around, and calling, Transaction.importAsUnconfirmed().
Tidied code around somelock.tryLock() to be more readable.
Controller (post-sync) now broadcasts new chaintip info if
our latest block's signature has changed, not simply the height.
Network.broadcast() only sends out via outbound peer if node has
more than one connection from the same peer. So Controller would
only update one of the peer records with chaintip info.
Controller now updates all connected peers with the ID when it
receives a HEIGHT or HEIGHT_V2 message.
Added node1 thru node7.mcfamily.io to default peers in Network.
Network ignores first "listen port" entry when receiving peers
list from an outbound-connection peer as it already knows
by virtue of having connected to it!
More network message debug logging (hopefully never to be seen).
[some old code left in, but commented out, for a while]
Remove fetching unconfirmed from Synchronizer
Add extra validity/reference/processable checks to
Transaction.isValidUnconfirmed
Update TransactionUtils to use Transaction.importAsUnconfirmed
for unit tests.
Added mass (x1000) testing of key conversion and shared secret calculations.
Fix incorrect proxy private key test that has expected result from previous
algorithm.
Added another test HTML/JS file.
HTML/JS in src/test/resources/proxy-key-example.html updated accordingly.
Add handshake status to output of API call GET /peers
Add/correct @ApiErrors annotations on some API calls.
Add API call POST /admin/orphan (target height as body)
to force blockchain orphaning for when node is wildly out of sync.
Added support for above to BlockChain class.
BlockGenerator now requires a minimum number of peers
before it will generate any new blocks.
See "minBlockchainPeers" in settings.
Controller now requires a minimum number of peers
before it will consider synchronizing.
See "minBlockchainPeers" in settings.
Old "minPeers" entry in settings.json no longer valid!
Networking now allows both an outbound and inbound connection
to a peer although will use the outbound connection in preference.
Networking checks peer ID of inbound connections to detect,
and resolve, peer ID clashes/theft.
Lots of edits to Transaction subclasses to change/remove 'delete'.
Corresponding extra changes to help reset some transaction fields to pre-process
state during orphaning.
Changed Block, GenesisBlock & Synchronizer to save transactions where appropriate.
Added enhanced GET_SIGNATURES_V2 network message to reduce the number of
block signatures sent over network.
Peers are now version 2 if they send a new-style build version string,
instead of using first digit from build version.
X25519 shared secrets now match those generated by libsodium.
New tests show that shared secrets are the same using either set
of private+public key combinations.
Changed proxy private key generation from using simple SHA256
of shared secret to using SHA256(shared secret + both public keys).
Added a temporary "BouncyCastle25519" shim class to provide missing
key conversion from Ed25519 to X25519.
After opening repository connection with RepositoryManager.getRepostory(),
any 'read' from repository (e.g. SELECT) starts the transaction
even though HSQLDB documentation states there are no shared/read locks
in MVCC concurrency model.
The work-around for this is to 'reset' HSQLDB's in-transaction flag
by performing a ROLLBACK (Repository.discardChanges) immediately
after acquiring the blockchain lock (which is used to ringfence
changes that might collide like these).
Also adding an extra check to prevent payments to nonexistent AT
addresses as it touches Transaction.
Move hard-coded forging tiers to blockchain config.
Tests for granting forging rights.
Added API call to list top block forgers.
Fixed typo with Reward[s]ByHeight class name.
Remove old whispersystems, etc. *25519 and use new v1.61 BouncyCastle.
Fix proxy forging private key derivation from X25519 shared secret.
Also include Javascript test version for comparison.
Fix block rewards for proxy forging.
Add extra useful info to API call GET /admin/forgingaccounts.
Fix API response to POST/DELETE /admin/forgingaccounts when
passed invalid private keys.
Added block rewards and account flags to testchain config.
Tests to cover changes above.
Also improved asset tests in that they don't use QORA any more
which takes fees/block rewards out of the picture.
More test assets are issued in the genesis block to
accomplish this:
1m TEST issued to Alice
1m OTHER issued to Bob
1m GOLD issued to Alice
Orders are back to having "amount" and "price".
(No more "unitPrice" or "wantAmount").
Order "amount" is expressed in terms of asset with highest
assetID.
"price" is expressed in (lowest-assetID)/(highest-assetID).
Given an order with two assets, e.g. QORA (0) and GOLD (31),
"amount" is in GOLD (31), "price" is in QORA/GOLD (0/31).
Order's "fulfilled" is in the same asset as "amount".
Yet more tests and debugging.
For simplicity's sake, the change to HSQLDB repository is
assumed to take place when 'new' pricing switch also
occurs.
Don't forget to change "newAssetPricingTimestamp" in
blockchain config JSON file.
Changed API call GET /assets to NOT return asset "data" fields
as they can be huge. If need be, call GET /assets/info to fetch
a specific asset's data field.
Improve asset trade amount granularity, especially for indivisible
assets, under "new" pricing scheme only.
Added corresponding tests for granularity adjustments.
Fix/unify asset order logging text under "old" and "new"
pricing schemes.
Change asset order related API data models so that old "price" is
now "unitPrice" and add new "return" as in amount of want-asset
to receive if have-asset "amount" was fully matched.
(Affects OrderData, CreateAssetOrderTransactionData)
Some changes to the HSQLDB tables.
Don't forget to add "newAssetPricingTimestamp" to your blockchain config's
"featureTriggers" map.
Better order matching, especially in situations
where inexact fractional representations (e.g. 1/12)
or rounding issues might occur. Also better matching
with indivisible assets.
Essentially change ordering from have-amount & price
to have-amount and want-return, leaving unit price
to be calculated internally to a finer degree (in
some cases to 48 decimal points).
Corresponding unit tests to cover both legacy and new
scenarios. Support for tests to switch between
blockchain configs.
"New" pricing schema is its own 'feature trigger'
independent from general qorav2 switch.
Safety checks added during trading process.
HSQLDB schema changes (will probably need
careful conflict resolution on merge).
Still to do:
API changes
etc.
+ unit test
+ newer unit test harness
but still needs:
BlockChain config support for activating newer "price" arg
New unit test to check old "price" arg usage
Rework existing asset-related unit tests
Check API inputs/output pre/post "price" arg crossover
GenesisBlock (v4) now supports various transaction types (issue-asset, etc.)
with generated signatures (like genesis transaction signature) and
missing references inserted.
JUnit reverted back to v4 for Eclipse support (for now).
