* core, core/vm, crypto: fixes for homesteadJeffrey Wilcke2016-02-181-1/+22
| | | | | | * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests

|
* core, eth, rpc: split out block validator and state processorJeffrey Wilcke2015-11-181-25/+0
| | | | | | | | | | | | 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).

* core, eth/filters, miner, xeth: Optimised log filteringJeffrey Wilcke2015-10-173-34/+76
| | | | | | | Log filtering is now using a MIPmap like approach where addresses of logs are added to a mapped bloom bin. The current levels for the MIP are in ranges of 1.000.000, 500.000, 100.000, 50.000, 1.000. Logs are therefor filtered in batches of 1.000.
* cmd/evm, core/vm, test: refactored VM and coreJeffrey Wilcke2015-10-043-13/+13
| | | | | | | | | | | | | | | | | * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.
* core, trie: new trieFelix Lange2015-09-231-7/+8
|
* core, core/types: readd transactions after chain re-orgJeffrey Wilcke2015-09-221-1/+23
| | | | | | | | | | | | | | 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
