Felix Lange	37dd9086ec	core: refactor genesis handling This commit solves several issues concerning the genesis block: * Genesis/ChainConfig loading was handled by cmd/geth code. This left library users in the cold. They could specify a JSON-encoded string and overwrite the config, but didn't get any of the additional checks performed by geth. * Decoding and writing of genesis JSON was conflated in WriteGenesisBlock. This made it a lot harder to embed the genesis block into the forthcoming config file loader. This commit changes things so there is a single Genesis type that represents genesis blocks. All uses of WriteGenesis are changed to use the new type instead. * If the chain config supplied by the user was incompatible with the current chain (i.e. the chain had already advanced beyond a scheduled fork), it got overwritten. This is not an issue in practice because previous forks have always had the highest total difficulty. It might matter in the future though. The new code reverts the local chain to the point of the fork when upgrading configuration. The change to genesis block data removes compression library dependencies from package core.	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

Viktor Trón	6c8b023298	contracts/chequebook: add chequebook contract wrapper The wrapper code is adapted from the swarm/services/chequebook package with the following mostly cosmetic changes: * The code now uses the new Go API interfaces to query balances. Some minor functional changes were required to make this work. * The package no longer depends on swarm/services/swap/swap. References to swap.Promise are replaced by interface{}, the base type of Promise. This is temporary. * The contract wrapper has been regenerated with latest abigen and solc v0.3.6. * There is a new generator that creates the 'deployed code' variable. * Documentation comments now follow the recommended godoc style. * [CHEQUEBOOK] log prefixes are gone. * LGPL license headers have been added to all files.	9 years ago
