* core: vm: refactor vm config and contextJhih-Ming Huang2019-05-061-2/+5
| | | | | | | | | | | | | | | | To support multiple VMs, there must be a shared execution environment for each VM, so this pull request moved some shared component to vm.Context and implemented the vm.ExecPack to hold the list of VM, list of VM configures, context and some shared resources. The adjustment includes: * Move NoRecursion, Depth, ReadOnly, RandCallIndex, IntPool and CallGasTemp to Context. * Adjust VM enumeration from byte to uint8, and the VMList from map to array. * Register VM constructor in each VM package's init function. * Initialize all VM instance in NewExecPack. * Remove EVMImplement, and modify EVM, such that EVM can do the same functions with EVMImplement.
* core: vm: refactor file structurejm2019-05-061-1/+1
| | | | | For support other vm types, this pr modified the core/vm file structures.

* core: refactor validator and fix light node sync (#25)Wei-Ning Huang2019-04-091-0/+1
| | | | | | | | 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.

* core, consensus: pluggable consensus engines (#3817)Péter Szilágyi2017-04-051-2/+2
| | | | | This commit adds pluggable consensus engines to go-ethereum. In short, it introduces a generic consensus interface, and refactors the entire codebase to use this interface.
* core: refactor genesis handlingFelix Lange2017-03-231-10/+8
| | | | | | | | | | | | | | | | | | | | | | | | This commit solves several issues concerning the genesis block: * Genesis/ChainConfig loading was handled by cmd/geth code. This left library users in the cold. They could specify a JSON-encoded string and overwrite the config, but didn't get any of the additional checks performed by geth. * Decoding and writing of genesis JSON was conflated in WriteGenesisBlock. This made it a lot harder to embed the genesis block into the forthcoming config file loader. This commit changes things so there is a single Genesis type that represents genesis blocks. All uses of Write*Genesis* are changed to use the new type instead. * If the chain config supplied by the user was incompatible with the current chain (i.e. the chain had already advanced beyond a scheduled fork), it got overwritten. This is not an issue in practice because previous forks have always had the highest total difficulty. It might matter in the future though. The new code reverts the local chain to the point of the fork when upgrading configuration. The change to genesis block data removes compression library dependencies from package core.

* params: core, core/vm, miner: 64bit gas instructionsJeffrey Wilcke2017-02-141-3/+3
| | | | | | | | | | | | | | | | | Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test

* core, core/state, trie: EIP158, reprice & skip empty account writeJeffrey Wilcke2016-11-131-2/+5
| | | | | | | | | | | | | | | This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke <jeffrey@ethereum.org>
* core/state: track all accounts in canon stateFelix Lange2016-09-261-1/+1
| | | | | This change introduces a global, per-state cache that keeps account data in the canon state. Thanks to @karalabe for lots of fixes.

* accounts/a/b/backends, core: chain maker homestead block set to 0Jeffrey Wilcke2016-04-011-1/+1
| | | | | | | The chain maker and the simulated backend now run with a homestead phase beginning at block 0 (i.e. there's no frontier). This commit also fixes up #2388
* core: added basic chain configurationJeffrey Wilcke2016-04-011-1/+1
| | | | | | | | | Added chain configuration options and write out during genesis database insertion. If no "config" was found, nothing is written to the database. Configurations are written on a per genesis base. This means that any chain (which is identified by it's genesis hash) can have their own chain settings.
* core, eth, rpc: split out block validator and state processorJeffrey Wilcke2015-11-181-5/+4
| | | | | | | | | | | | This removes the burden on a single object to take care of all validation and state processing. Now instead the validation is done by the `core.BlockValidator` (`types.Validator`) that takes care of both header and uncle validation through the `ValidateBlock` method and state validation through the `ValidateState` method. The state processing is done by a new object `core.StateProcessor` (`types.Processor`) and accepts a new state as input and uses that to process the given block's transactions (and uncles for rewords) to calculate the state root for the next block (P_n + 1).

| | | | | | * Renamed ChainManager to BlockChain * Checkpointing is no longer required and never really properly worked when the state was corrupted.
* core, core/types: readd transactions after chain re-orgJeffrey Wilcke2015-09-221-1/+1
| | | | | | | | | | | | | | Added a `Difference` method to `types.Transactions` which sets the receiver to the difference of a to b (NOTE: not a **and** b). Transaction pool subscribes to RemovedTransactionEvent adding back to those potential missing from the chain. When a chain re-org occurs remove any transactions that were removed from the canonical chain during the re-org as well as the receipts that were generated in the process. Closes #1746
