* core, core/vm, crypto: fixes for homesteadJeffrey Wilcke2016-02-189-74/+123
| | | | | | * 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 Simonsson2016-02-1810-37/+94
| | | | | | | | * 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/vm/runtime: simplified runtime calling mechanismJeffrey Wilcke2016-02-112-6/+93
| | | | | | Implemented `runtime.Call` which uses - unlike Execute - the given state for the execution and the address of the contract you wish to execute. Unlike `Execute`, `Call` requires a config.

|
* core/vm/runtime: added simple execution runtimeJeffrey Wilcke2015-11-185-0/+399
| | | | | | The runtime environment can be used for simple basic execution of contract code without the requirement of setting up a full stack and operates fully in memory.

| * core/vm: abstracted instruction execution away from JITJeffrey Wilcke2015-10-172-76/+88
| | | | | | | | | | | | Moved the execution of instructions to the instruction it self. This will allow for specialised instructions (e.g. segments) to be execution in the same manner as regular instructions.

* cmd/evm, core/vm, test: refactored VM and coreJeffrey Wilcke2015-10-0418-829/+764
| | | | | | | | | | | | | | | | | * 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`.

| | | | | opNumber did not create a new big int which could lead to the block's number being modified.

|
* core/vm: reduced big int allocationsJeffrey Wilcke2015-08-073-122/+77
| | | | | | | Reduced big int allocation by making stack items modifiable. Instead of adding items such as `common.Big0` to the stack, `new(big.Int)` is added instead. One must expect that any item that is added to the stack might change.
* core, tests: reduced state copy by N callsJeffrey Wilcke2015-08-075-1/+8
| | | | | 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 Wilcke2015-08-079-64/+1356
| | | | * changed stack and removed stack ptr. Let go decide on slice reuse.

| | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".
