* core: transition db now also returns the required gas amountJeffrey Wilcke2016-04-011-7/+24
| | | | | | | | | Exposes some core methods to transition and compute new state information and adds an additional return value to the transition db method to fetch required gas for that particular message (excluding gas refunds from any SSTORE[X] = 0 and SUICIDE. Fixes #2395
* core: added basic chain configurationJeffrey Wilcke2016-04-011-2/+2
| | | | | | | | | 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: Added EVM configuration optionsJeffrey Wilcke2016-03-241-5/+1
| | | | | The EVM is now initialised with an additional configured object that allows you to turn on debugging options.

* | core, core/vm, crypto: fixes for homesteadJeffrey Wilcke2016-02-181-27/+12

* | 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`.

| | | | I forgot to update one instance of "go-ethereum" in commit 3f047be5a.
* 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".
