towards generic method polling and reposito;y; config settings to
filterevents/methods by account address; refactoring some stuff out of
repo and into converter; remove fetcher and instead call
blockchain's FetchContractData directly; finishing tests
- Previously, a block was treated as missing if there was a number in
the given range for which there existing a block that did not match
the node's fingerprint. This meant that in a case where we have a block
that does not match the node's fingerprint and also one that does match,
the block would be treated as missing. This led to errors being thrown
when attempting to add a block that already exists.
- These changes treat a block as missing only if we do not already have
a block that matches the number and node fingerprint.
= Add eth_node_fingerprint to block that can be imitated by both hot and cold imports
- Only sync missing blocks (blocks that are missing or don't share a fingerprint) on cold import
- Set block is_final status after import
- Allows us to fetch receipts by block and persist even when
associated transaction is unknown. (The associated transaction
can still be derived from the tx_hash column at query time, but
is an expensive operation to require for inserts).
