* params: core, core/vm, miner: 64bit gas instructionsJeffrey Wilcke2017-02-141-67/+11
| | | | | | | | | | | | | | | | | Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test

* core: Added EVM configuration optionsJeffrey Wilcke2016-03-241-5/+0
| | | | | 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 Wilcke2016-03-231-14/+0
| | | | | | | 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.
* core/vm, rpc/api: renamed to debug.replayTransaction, migrated to new RPC, ↵Peter Pratscher2016-02-021-0/+2

* cmd/geth, cmd/utils, core, rpc: renamed to blockchainJeffrey Wilcke2015-10-041-2/+2
| | | | | | * Renamed ChainManager to BlockChain * Checkpointing is no longer required and never really properly worked when the state was corrupted.
* cmd/evm, core/vm, test: refactored VM and coreJeffrey Wilcke2015-10-041-12/+43
| | | | | | | | | | | | | | | | | * 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: fix license headers one more timeFelix Lange2015-07-241-1/+1
| | | | 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".
