When a consensus divergance occurs, the current workflow involves a
handful of manual steps to hone in on the offending slot and
transaction. This process isn't overly difficult to execute; however, it
is tedious and currently involves creating and parsing logs.
This change introduces functionality to output a debug file that
contains the components go into the bank hash. The file can be generated
in two ways:
- Via solana-validator when the node realizes it has diverged
- Via solana-ledger-tool verify by passing a flag
When a divergance occurs now, the steps to debug would be:
- Grab the file from the node that diverged
- Generate a file for the same slot with ledger-tool with a known good
version
- Diff the files, they are pretty-printed json
