Nick Johnson	781915f183	core/vm: Refactor tracing to make Tracer the main interface ... This CL makes several refactors: - Define a Tracer interface, implementing the `CaptureState` method - Add the VM environment as the first argument of `Tracer.CaptureState` - Rename existing functionality `StructLogger` an make it an implementation of `Tracer` - Delete `StructLogCollector` and make `StructLogger` collect the logs directly - Change all callers to use the new `StructLogger` where necessary and extract logs from that. - Deletes the apparently obsolete and likely nonfunctional 'TraceCall' from the eth API. Callers that only wish accumulated logs can use the `StructLogger` implementation straightforwardly. Callers that wish to efficiently capture VM traces and operate on them without excessive copying can now implement the `Tracer` interface to receive VM state at each step and do with it as they wish. This CL also removes the accumulation of logs from the vm.Environment; this was necessary as part of the refactor, but also simplifies it by removing a responsibility that doesn't directly belong to the Environment.	8 years ago

Jeffrey Wilcke	f0cbebb19f	core: added basic chain configuration ... 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.	9 years ago
Jeffrey Wilcke	14013372ae	core: Added EVM configuration options ... The EVM is now initialised with an additional configured object that allows you to turn on debugging options.	9 years ago
Jeffrey Wilcke	342ae7ce7d	core, core/vm, tests: changed the initialisation behaviour of the EVM ... 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.	9 years ago

Jeffrey Wilcke	b6d88a0e9f	core, core/vm, crypto: fixes for homestead ... * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests	9 years ago
Gustav Simonsson	371871d685	parmas, crypto, core, core/vm: homestead consensus protocol changes ... * 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	9 years ago

Jeffrey Wilcke	361082ec4b	cmd/evm, core/vm, test: refactored VM and core ... * 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`.	9 years ago

Felix Lange	ea2718c946	core/vm: improve JUMPDEST analysis ... * JUMPDEST analysis is faster because less type conversions are performed. * The map of JUMPDEST locations is now created lazily at the first JUMP. * The result of the analysis is kept around for recursive invocations through CALL/CALLCODE.

obscuren	1c872ddf4b	Changed how logs are being recorded ... Logs are now recorded per transactions instead of tossing them out after each transaction.
