* | core, core/vm, crypto: fixes for homesteadJeffrey Wilcke2016-02-181-27/+12
| | | | | | | | | | | | * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests
* | parmas, crypto, core, core/vm: homestead consensus protocol changesGustav Simonsson2016-02-181-6/+39
|/ | | | | | | | * change gas cost for contract creating txs * invalidate signature with s value greater than secp256k1 N / 2 * OOG contract creation if not enough gas to store code * new difficulty adjustment algorithm * new DELEGATECALL op code
* core, core/state: move gas tracking out of core/stateFelix Lange2015-10-171-23/+27
| | | | | | | The amount of gas available for tx execution was tracked in the StateObject representing the coinbase account. This commit makes the gas counter a separate type in package core, which avoids unintended consequences of intertwining the counter with state logic.
* cmd/evm, core/vm, test: refactored VM and coreJeffrey Wilcke2015-10-041-31/+36
| | | | | | | | | | | | | | | | | * 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`.

* all: update license headers to distiguish GPL/LGPLFelix Lange2015-07-231-4/+4
| | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".
