Felix Lange	1f1ea18b54	core/state: implement reverts by journaling all changes This commit replaces the deep-copy based state revert mechanism with a linear complexity journal. This commit also hides several internal StateDB methods to limit the number of ways in which calling code can use the journal incorrectly. As usual consultation and bug fixes to the initial implementation were provided by @karalabe, @obscuren and @Arachnid. Thank you!	8 years ago
Péter Szilágyi	cb84e3f029	cmd, core, internal, light, tests: avoid hashing the code in the VM	8 years ago
Felix Lange	a59a93f476	core/state: track all accounts in canon state This change introduces a global, per-state cache that keeps account data in the canon state. Thanks to @karalabe for lots of fixes.	8 years ago
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
Péter Szilágyi	6362a9d610	Revert "test, cmd/evm, core, core/vm: illegal code hash implementation" This reverts commit `7a5b571c67`.	8 years ago
Jeffrey Wilcke	7a5b571c67	test, cmd/evm, core, core/vm: illegal code hash implementation 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.	8 years ago
zsfelfoldi	3a97280ae8	eth: separate common and full node-specific API and backend service	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
Leif Jurvetson	b7bb2d8589	core: various typos	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
Péter Szilágyi	752c75fb21	core/vm: resolve circular dependency to debug vm storage	9 years ago
Jeffrey Wilcke	80f26086ee	core, tests: get_hash fix Make sure that we're fetching the hash from the current chain and not the canonical chain.	9 years ago
Gustav Simonsson	e1616f77c7	core, core/vm, cmd/evm: remove redundant balance check	9 years ago
Jeffrey Wilcke	7c7692933c	cmd/geth, cmd/utils, core, rpc: renamed to blockchain * Renamed ChainManager to BlockChain * Checkpointing is no longer required and never really properly worked when the state was corrupted.	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

Jeffrey Wilcke	184e9ae9a8	core, tests: reduced state copy by N calls Reduced the amount of state copied that are required by N calls by doing a balance check prior to any state modifications.	9 years ago
Felix Lange	bfbcfbe4a9	all: fix license headers one more time I forgot to update one instance of "go-ethereum" in commit `3f047be5a`.	9 years ago
Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago

obscuren	fa4aefee44	core/vm: cleanup and renames	9 years ago
obscuren	1c872ddf4b	Changed how logs are being recorded Logs are now recorded per transactions instead of tossing them out after each transaction. This should also fix an issue with `eth_getFilterLogs` (#629) Also now implemented are the `transactionHash, blockHash, transactionIndex, logIndex` on logs. Closes #654.	10 years ago

obscuren	99853ac3ce	Moved execution from vm to chain. This moves call and create to the specified environments. Vms are no longer re-used. Vm uses environment's Call(Code) and Create in order to execute new contracts or transfer value between accounts. State transition now uses the same mechanism described above.	10 years ago
