* Add validation functions to be used in state portal rpc.
* Add validation to remaining state portal rpc methods.
* Lookup local content in recursiveFindContent rpc methods.
* portal_stateFindContent and portal_stateOffer no longer store in db.
These create only confusion as if they are actual different types
and it is within their usage already clear what they are about
because of the name of the variable or the function.
They are also nowhere aliased like this in any of the Portal
specification.
* Fix eth/common & web3 related deprecation warnings for fluffy
This commit uses the new types in the new eth/common/ structure
to remove deprecation warnings.
It is however more than just a mass replace as also all places
where eth/common or eth/common/eth_types or eth/common/eth_types_rlp
got imported have been revised and adjusted to a better per submodule
based import.
There are still a bunch of toMDigest deprecation warnings but that
convertor is not needed for fluffy code anymore so in theory it
should not be used (bug?). It seems to still get imported via export
leaks ffrom imported nimbus code I think.
* Address review comments
* Remove two more unused eth/common imports
This is a minimal set of changes to make things work with the new types
in nim-eth - this is the minimal PR that merely resolves
incompatibilities while the full change set would include more cleanup
and migration.
* Return default values when account, slot or code doesn't exist.
* Handle case when storage doesn't exist due to account not existing or being a non contract account.
* Update state network to use addressHash instead of address in contract trie and contract code content keys.
* Fix path calculation bug in getParent when working with extension nodes.
* Bump portal spec tests repo.
* Finish updating tests due to portal test vector changes.
* Update Fluffy state bridge to use addressHash.
* Update Fluffy book with correct commands for running portal hive tests.
* Create block offers queue and collect account preimages.
* Implement iterators to return account and storage proofs and bytecode from updatedCaches.
* Implement building offers from proofs.
* Refactor BlockDataRef type to only include required fields.
* Store block data in database.
* Improve state diff types.
* Implement start state backfill from specific block.
* Record last persisted block number in database.
* Persist account preimages in db.
* Apply state updates for DAO hard fork.
* Implement state gossip of block offers via portal JSON RPC.
* Add toContentKey helper functions.
* Implement typed lookup functions for getting account and storage trie nodes and bytecode.
* Re-implementation of recursive gossip.
* Offer validation improvements. Don't allow key end in Nibbles for leafs as defined in the spec.
* Minor refactor to validation and add addition bytecode check.
