* Revert "test, cmd/evm, core, core/vm: illegal code hash implementation"Péter Szilágyi2016-06-291-1/+0
| | | | This reverts commit 7a5b571c671e70e0e4807cf971c15e2d1e09d33d.
* test, cmd/evm, core, core/vm: illegal code hash implementationJeffrey Wilcke2016-06-221-0/+1
| | | | | | | | This implements a generic approach to enabling soft forks by allowing anyone to put in hashes of contracts that should not be interacted from. This will help "The DAO" in their endevour to stop any whithdrawals from any DAO contract by convincing the mining community to accept their code hash.
* cmd/evm: added --create flag indicating the exec code is to be createdJeffrey Wilcke2016-06-141-11/+34
| | | | | | | | | | This fixes an issue if you wanted to test out code deployment rather than running a piece of code with an argument. This solves it by adding a --create flag that indicates the Create function should be used rather than the Call function. This also adds a statedb.commit call so that the proper state can be dumped when requested using the --dump flag.
* cmd: fix CLI package deprecation warningsPéter Szilágyi2016-06-101-1/+2

* cmd/geth: codegansta/cli package renamed to urfave/cliBas van Kervel2016-06-091-1/+1

* core: added basic chain configurationJeffrey Wilcke2016-04-011-8/+11
| | | | | | | | | 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 Wilcke2016-03-241-6/+9
| | | | | The EVM is now initialised with an additional configured object that allows you to turn on debugging options.
* core, core/vm, tests: changed the initialisation behaviour of the EVMJeffrey Wilcke2016-03-231-1/+8
| | | | | | | The EVM was previously initialised and created for every CALL, CALLCODE, DELEGATECALL and CREATE. This PR changes this behaviour so that the same EVM can be used through the session and beyond as long as the Environment sticks around.
* parmas, crypto, core, core/vm: homestead consensus protocol changesGustav Simonsson2016-02-181-0/+5
| | | | | | | | * 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

* cmd/evm, core/vm, test: refactored VM and coreJeffrey Wilcke2015-10-041-33/+31
| | | | | | | | | | | | | | | | | * 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, tests: reduced state copy by N callsJeffrey Wilcke2015-08-071-0/+3
| | | | | Reduced the amount of state copied that are required by N calls by doing a balance check prior to any state modifications.
* core/vm, tests: implemented semi-jit vmJeffrey Wilcke2015-08-071-6/+20
| | | | * changed stack and removed stack ptr. Let go decide on slice reuse.
* cmd/core,xeth: removed unneeded states & added batch writesJeffrey Wilcke2015-07-231-31/+81

* all: update license headers to distiguish GPL/LGPLFelix Lange2015-07-231-2/+2
| | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".
