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- The functionality of block.NewHeaderWith has been replaced by the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.
