* indexer: support data exporting/forwarding (#103)Meng-Ying Yang2019-03-122-0/+19
| | | | | | | | | To support more effective and flexible blockchain info exploring, we add `indexer` package, defines the flow of indexer dameon, and integrate into dex.Dexon fullnode. For more export options, we use Golang built-in `plugin` package to support mulitple implementations.
* dex/downloader: fix bug when syncing (#106)Sonic2019-03-121-2/+13
| | | | | Since blocks will interleave around round change, we will probably need to verify blocks at previous round.
* dex: add pull randomness (#105)Jimmy Hu2019-03-126-14/+203
| | | | | * vendor: sync to latest core * dex: Add PullRandomness
* core, dex, internal: block proposer syncing (first iteration) (#96)Sonic2019-03-125-24/+247
| | | | | | | | | | | | | | | | | | | | | | * dex, internal: block proposer syncing (first iteration) * core: find block from db if not in memory This fix handles stopping proposing and then restarting * core: no need to reorg when reset Dexon will not fork. This commit also fix when a block confirm but its parent is not in db yet, during restarting proposing. * dex: always accept NewBlockMsg, NewBlockHashesMsg We need to accept NewBlockMsg, NewBlockHashesMsg to sync current block with other peers in block proposer mode when syncing lattice data. It's a waste when the node is synced and start proposing. Todo: control msg processing on/off more granular, accept NewBlockMsg, NewBlockHashesMsg when syncing, but stop when synced.
* core: vm: Add `MPKReady` to governance (#97)Jimmy Hu2019-03-121-0/+40

|
* core, dex: polish sync (#75)Sonic2019-03-126-8/+79
| | | | | | | | | | | | | | | - Broadcasting blocks at chain head event is not correct when the full node is not running in block proposer mode. Introduce NewFinalizedBlockEvent, this event is post by the full node which runs in block proposer mode when a block is witnessed and resulting in some blocks are considered finalized. - Non block proposer node will still broadcast blocks at the following moment (same as ethereum): 1. a sync with a peer is terminated successfully 2. a block passes the fetcher's header check during inserting blocks 3. a block is successfully inserted by fetcher - Don't trigger a sync when we are not behind other peers more than acceptable distance. Fetcher is able to cover this.
* app: misc fixes (#76)bojie2019-03-121-50/+30
| | | | Use sync map to prevent concurrent read write. Use last pending state to prepare/verify transactions.
* dex: replace total difficulty with block number (#73)Sonic2019-03-1210-177/+143
| | | | | | | In dexon, we don't "mine" and the blockchain won't and shouldn't fork, so there is no difficulty concept, just replace it with block number. Note: this commit only replace total difficulty related logic and code in dex, dex/downloader package.

* core, dex, dex/downloader: restore insertChain to upstream versionSonic2019-03-122-7/+7
| | | | | Also rename InsertChain2, insertChain2, InsertHeaderChain2, ValidateHeaderChain2
* dex: implement downloader for dexSonic2019-03-1211-88/+499
| | | | | | | | | | | We need governance state to verify block's signature (randomness), but in ethereum fast sync mode, eth downloader only downloads the whole state of pivot block, so we don't have governance state to verify the downloaded block that is before pivot block if we don't processing transaction. To avoid running transactions, dex downloader also downloads the governance state (merkle proof and storage) at snapshot height of each round, so that we can verify blocks in fast sync mode.
* dex: use dex/downloader in dexSonic2019-03-128-19/+19
| | | | | To compatible with ethereum code base, make Downloader a interface in internal/ethapi

* core: add global signature cache and improve concurrency (#42)Wei-Ning Huang2019-03-122-2/+2
| | | | | From the go trace result, the bottleneck hides in the lock of StoreTxCache. To improve this, we update the cache in a batched fassion.

* core: more fix on light node synchronization (#32)Wei-Ning Huang2019-03-122-8/+7
| | | | | | Fix gas calculation in governance contract. Correctly register round height when processing pending blocks. We should register the mapping when we get the pending block instead of waiting for block confirmation.

* core: refactor validator and fix light node sync (#25)Wei-Ning Huang2019-03-123-47/+75
| | | | | | | | Remove custom Dexon validator by adding a new `ValidateWitnessData` method into the validator interface. This allow us to properly detect know blocks. This also allow other gdex "light" client to sync compaction chain. Also, setup a standalone RPC node for handling RPC reqeusts.
