Felix Lange	7731061903	core/vm: move Log to core/types ... This significantly reduces the dependency closure of ethclient, which no longer depends on core/vm as of this change. All uses of vm.Logs are replaced by []*types.Log. NewLog is gone too, the constructor simply returned a literal.	8 years ago
Jeffrey Wilcke	bbc4ea4ae8	core/vm: improved EVM run loop & instruction calling (#3378) ... The run loop, which previously contained custom opcode executes have been removed and has been simplified to a few checks. Each operation consists of 4 elements: execution function, gas cost function, stack validation function and memory size function. The execution function implements the operation's runtime behaviour, the gas cost function implements the operation gas costs function and greatly depends on the memory and stack, the stack validation function validates the stack and makes sure that enough items can be popped off and pushed on and the memory size function calculates the memory required for the operation and returns it. This commit also allows the EVM to go unmetered. This is helpful for offline operations such as contract calls.	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
Jeffrey Wilcke	4dca5d4db7	core/types, params: EIP#155	8 years ago
Jeffrey Wilcke	445feaeef5	core, core/state, trie: EIP158, reprice & skip empty account write ... This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke <jeffrey@ethereum.org>	8 years ago
Jeffrey Wilcke	64af2aafda	core, core/vm: added gas price variance table ... This implements 1b & 1c of EIP150 by adding a new GasTable which must be returned from the RuleSet config method. This table is used to determine the gas prices for the current epoch. Please note that when the CreateBySuicide gas price is set it is assumed that we're in the new epoch phase. In addition this PR will serve as temporary basis while refactorisation in being done in the EVM64 PR, which will substentially overhaul the gas price code.	8 years ago
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
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

Felix Lange	d04a2e7557	all: update license information	9 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
Gustav Simonsson	1b1f293082	core/state, core, miner: handle missing root error from state.New	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	9cacec70f9	cmd/evm, core/vm, tests: changed DisableVm to EnableVm	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
