We were ignoring quite a few error cases, and had one case where we weren't
actually updating state where we wanted to. Unfortunately, if the linter doesn't
pass, nobody has any reason to actually check lint failures in CI.
There are three remaining XXXs marked in the code for lint.
- When chainwatch is ran it will first start a Syncer that continuously collects blocks from the
ChainNotify channel and persists them to the blocks_synced table. Once the Syncer has caught the
blocks_synced table up to the lotus daemons current head a Processor is started. The Processor
selects a batch of contiguous blocks and extracts and stores their data. It attempts to do as much
work as it can in parallel. When the blocks are done being processed their corresponding
processed_at and is_processed fields in the blocks_synced table are filled out.
