kiel barry	a7720b5926	core: golint updates for this or self warning (#16633)	6 years ago
Jeffrey Wilcke	024d41d0c2	core, core/state, core/vm: remove exported account getters (#3618) ... Removed exported statedb object accessors, reducing the chance for nasty bugs to creep in. It's also ugly and unnecessary to have these methods.	8 years ago
Jeffrey Wilcke	c12f4df910	params: core, core/vm, miner: 64bit gas instructions ... 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	8 years ago
Jeffrey Wilcke	57f4e90257	Revert "params: core, core/vm, miner: 64bit gas instructions (#3514)" ... This reverts commit 8b57c49490.	8 years ago

Jeffrey Wilcke	3fc7c97827	core, core/vm: implemented a generic environment (#3348) ... Environment is now a struct (not an interface). This reduces a lot of tech-debt throughout the codebase where a virtual machine environment had to be implemented in order to test or run it. The new environment is suitable to be used en the json tests, core consensus and light client.	8 years ago
Péter Szilágyi	cb84e3f029	cmd, core, internal, light, tests: avoid hashing the code in the VM	8 years ago
Felix Lange	d04a2e7557	all: update license information	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	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	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	846f34f78b	core/vm, tests: implemented semi-jit vm ... * changed stack and removed stack ptr. Let go decide on slice reuse.	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
Felix Lange	ea54283b30	all: update license information	9 years ago

obscuren	468501cb86	core/vm: changed program counter to uint64	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. Fixes #1147	9 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

obscuren	c5bd32b0ad	Refactored VM to two separate VMs; std & debug ... Standard VM should be about 10x faster than the debug VM. Some error checking has been removed, all of the log statements and therefor quite some unnecessary if-statements.	10 years ago
