Now that nodes correctly populate position field in coding shreds, and
first_coding_index in erasure meta, the old code to maintain backward
compatibility can be removed.
The commit is working towards changing erasure coding schema to 32:64.
SlotMeta.last_index may be unknown and current code is using u64::MAX to
indicate that:
https://github.com/solana-labs/solana/blob/6c108c8fc/ledger/src/blockstore_meta.rs#L169-L174
This lacks type-safety and can introduce bugs if not always checked for
Several instances of slot_meta.last_index + 1 are also subject to
overflow.
This commit updates the type to Option<u64>. Backward compatibility is
maintained by customizing serde serialize/deserialize implementations.
https://github.com/solana-labs/solana/pull/16646
removed first_coding_index since the field is currently redundant and
always equal to fec_set_index.
However, with upcoming changes to erasure coding schema, this will no
longer be the same as fec_set_index and so requires a separate field to
represent.
* Add `ProgramCosts` Column Family to blockstore, implement LedgerColumn; add `delete_cf` to Rocks
* Add ProgramCosts to compaction excluding list alone side with TransactionStatusIndex in one place: `excludes_from_compaction()`
* Write cost table to blockstore after `replay_stage` replayed active banks; add stats to measure persist time
* Deletes program from `ProgramCosts` in blockstore when they are removed from cost_table in memory
* Only try to persist to blockstore when cost_table is changed.
* Restore cost table during validator startup
* Offload `cost_model` related operations from replay main thread to dedicated service thread, add channel to send execute_timings between these threads;
* Move `cost_update_service` to its own module; replay_stage is now decoupled from cost_model.
* Add blockstore column to store performance sampling data
* introduce timer and write performance metrics to blockstore
* introduce getRecentPerformanceSamples rpc
* only run on rpc nodes enabled with transaction history
* add unit tests for get_recent_performance_samples
* remove RpcResponse from rpc call
* refactor to use Instant::now and elapsed for timer
* switch to root bank and ensure not negative subraction
* Add PerfSamples to purge/compaction
* refactor to use Instant::now and elapsed for timer
* switch to root bank and ensure not negative subraction
* remove duplicate constants
