- breaks dependency from staged_sync to package with block_reader
implementation
- breaks dependency from snap_sync to package with block_reader
implementation
- breaks dependency from mining to txpool implementation
- allow store non-canonical blocks/senders
- optimize re-org: don't update/delete most of data
- allow mark chain as `Bad` - will be not visible by eth_getBlockByHash,
but can read if have hash+num
- stage_senders: don't re-calc existing senders
- stage_tx_lookup: prune less blocks per iteration - because
random-deletes are expensive. pruning must not slow-down sync.
- prune data even if --snap.stop is set
- "prune as-much-as-possible at startup" is not very good idea: at
initialCycle machine can be cold and prune will cause big downtime, no
reason to produce much freelist in 1 tx. People may also restart erigon
- because of some bug - and it will cause unexpected downtime (usually
Erigon startup very fast). So, I just remove all `initialSync`-related
logic in pruning.
- fix lost metrics about disk write byte/sec
