* continue importing rlp blocks
why:
a chain of blocks to be imported might have legit blocks
after rejected blocks
details:
import loop only stops if the import list is exhausted or if there
was a decoding error. this adds another four to the count of successful
no-hive tests.
* verify DAO marked extra data field in block header
why:
was ignored, scores another two no-hive tests
* verify minimum required difficulty in header validator
why:
two more nohive tests to succeed
details:
* subsumed extended header tests under validateKinship() and renamed it
more appropriately validateHeaderAndKinship()
* enhanced readability of p2p/chain.nim
* cleaned up test_blockchain_json.nim
* verify positive gasUsed unless no transactions
why:
solves another to nohive tests
details:
straightened test_blockchain_json chech so there is no unconditional
rejection anymore (based on the input test scenario)
* Re-adjust canonical head to parent of block to be inserted
why:
of the failing tests that remain to be solved, 30 of those will succeed
if the canonical database chain head is cleverly adjusted -- yes, it
looks like a hack, indeed.
details:
at the moment, this hack works for the non-hive tests only and is
triggered by a boolean argument passed on to the chain.persistBlocks()
method.
* Use parent instead of canonical head for block to be inserted
why:
side chains need to be inserted typically somewhere before the
canonical head.
details:
the previous _hack_ was unnecessary and removed, it was inspired by
some verification in persistBlocks() which explicitly referenced the
canonical head (which now might or might not refer to the newly inserted
header.)
* remove unnecessary code + comment
