Adds checks to ignore a block that's already known (can happen
if the block was saved but the chain update failed). Also saves
saves the chain slightly differently during bootstrap as the
header chain should only be updated when a header is received
(and not when we got a full block). Finally, do not broadcast
during bootstrap.
Save outputs in every new block under their own hash. Done in the
same batch as the block. Allows for direct output lookups by hash
required by the p2p layer. Also store an index of output
commitment to output hash for wallet and input lookups.
* core: cleanup slicing impls for Hash
* core: clean up Readable trait, implement Readable/Writeable for various integers
* core: change Hash debug output to hex
* core: correct warnings in all modules
* Replace AsFixedBytes with Sized + AsRef<[u8]>
* Add AsRef<u8> to impl_array_newtype!
* Include AsFixedBytes as marker trait
* Related fixes
* Remove Deref
Block, Output and Kernel now have bitmasks to hold supported
features and eventually versioning. Will make adding features and
updates easier and open the possibility of soft forks.
First added feature for Output and Kernel is the marking of coinbase
related ones. Allows the validation of the coinbase part of a block.
* use MESSAGE_SIZE constant instead of 32
* use Hashed trait in genesis
* safer serialization of Hash
* Hashed of [u8] should send only data to hash function, not length + data
* Safer serialization of Proof
* Safer serialization of Commitment
* Safer serialization of RangeProof
* introduce read_limited_vec instead of potential panic in conversion
