Eugene Kim	576292bb9e	Add Copy method to the Header interface	5 years ago
Eugene Kim	d35cba2d44	Move block.HeaderInterface → blockif.Header ... This is to make it possible to use the Header interface from implementations without causing cyclic imports.	5 years ago

Eugene Kim	8ac058bb2e	Version headers ... block.Header is now a lightweight wrapper around an embedded HeaderInterface value, which is implemented by both v0 and v1 headers. It inherits all methods from the wrapped HeaderInterface, except it overrides EncodeRLP, DecodeRLP, and Hash to handle tagged-RLP encoding/decoding. (block.HeaderRegistry is the tagged RLP registry for versioned headers.) A ripple effect is that header instance creation now requires knowledge of epoch. This logic is handled by blockfactory. blockfactory.Factory is the interface, implemented by blockfactory.factory type. It uses a chain config to pull in the right epoch for the right type. As a convenience, blockfactory.NewTestHeader creates a new test-purpose headers. Use this in contexts where the implied chain config is TestChainConfig or the chain config does not matter. Miscellaneous changes: - block.HeaderFieldSetter now lives in its own file. - The functionality of block.NewHeaderWith has been replaced by the (*block.Header).With method. The accompanying unit tests for (*block.Header).EncodeRLP and (*block.Header).DecodeRLP() are the cross-sectional unit tests for the functionality added by this. They make sure that v0 header is encoded/decoded without tagged RLP envelope (compatibility mode), and v1 header is encoded/decoded with one. See comments of the RLP byte sequence for differences.	5 years ago

Eugene Kim	453d4fe3b6	Import Ethereum's core/types as ethtypes	5 years ago
Eugene Kim	7c56c816de	Copy v1 header into v0	5 years ago
Eugene Kim	31d53dbdf6	Move v1 Header and friends into block/v1	5 years ago
Eugene Kim	70a2ce4f01	Move Header and NewHeader into headerv1.go ... This file will move into block/v1 directory.	5 years ago
Eugene Kim	e1dff26b84	Create a new instance when setting big.Int fields ... That is, do not reuse the existing one, because it may be shared by multiple header instances. The goal here is to make it safe to value-copy header structs.	5 years ago
Eugene Kim	8cc2543c9e	Move header fields into private struct; expose them using getters/setters ... Also introduce NewHeader and NewHeaderWith functions. The latter is friendlier for create-and-initialize expressions, and can be used in place of the old &Header{field: value, ...} syntax.	5 years ago
Eugene Kim	d26525af63	shard.ShardState → shard.State to reduce stutter ... Pointed out by golint.	5 years ago
Eugene Kim	a48123e749	Move (core/)types.Header and friends into block	5 years ago
