Felix Lange	9e5f03b6c4	core/state: access trie through Database interface, track errors (#14589) ... With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).	7 years ago

Jeffrey Wilcke	10a57fc3d4	consensus, core/*, params: metropolis preparation refactor ... This commit is a preparation for the upcoming metropolis hardfork. It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)	8 years ago
Felix Lange	0cc492f815	all: update license information	8 years ago

Jeffrey Wilcke	bf4155846c	core/evm, core/vm: improved evm trace output ... * Improved the standard evm tracer output and renamed it to WriteTrace which now takes an io.Writer to write the logs to. * Added WriteLogs which writes logs to the given writer in a readable format. * evm utility now also prints logs generated during the execution.	8 years ago
Jeffrey Wilcke	230cf2ec91	cmd/evm, core/asm: add EVM assembler (#3686) ... The evm compile command implements a simple assembly language that compiles to EVM bytecode.	8 years ago
Felix Lange	5f7826270c	all: unify big.Int zero checks, use common/math in more places (#3716) ... * common/math: optimize PaddedBigBytes, use it more name old time/op new time/op delta PaddedBigBytes-8 71.1ns ± 5% 46.1ns ± 1% -35.15% (p=0.000 n=20+19) name old alloc/op new alloc/op delta PaddedBigBytes-8 48.0B ± 0% 32.0B ± 0% -33.33% (p=0.000 n=20+20) * all: unify big.Int zero checks Various checks were in use. This commit replaces them all with Int.Sign, which is cheaper and less code. eg templates: func before(x *big.Int) bool { return x.BitLen() == 0 } func after(x *big.Int) bool { return x.Sign() == 0 } func before(x *big.Int) bool { return x.BitLen() > 0 } func after(x *big.Int) bool { return x.Sign() != 0 } func before(x *big.Int) int { return x.Cmp(common.Big0) } func after(x *big.Int) int { return x.Sign() } * common/math, crypto/secp256k1: make ReadBits public in package math	8 years ago
