* Clarifying/commenting FCU setup condition & small fixes, comments etc.
* Update some logging
* Reorg metrics updater and activation
* Better `async` responsiveness
why:
Block import does not allow `async` task activation while
executing. So allow potential switch after each imported
block (rather than a group of 32 blocks.)
* Handle resuming after previous sync followed by import
why:
In this case the ledger state is more recent than the saved
sync state. So this is considered a pristine sync where any
previous sync state is forgotten.
This fixes some assert thrown because of inconsistent internal
state at some point.
* Provide option for clearing saved beacon sync state before starting syncer
why:
It would resume with the last state otherwise which might be undesired
sometimes.
Without RPC available, the syncer typically stops and terminates with
the canonical head larger than the base/finalised head. The latter one
will be saved as database/ledger state and the canonical head as syncer
target. Resuming syncing here will repeat itself.
So clearing the syncer state can prevent from starting the syncer
unnecessarily avoiding useless actions.
* Allow workers to request syncer shutdown from within
why:
In one-trick-pony mode (after resuming without RPC support) the
syncer can be stopped from within soavoiding unnecessary polling.
In that case, the syncer can (theoretically) be restarted externally
with `startSync()`.
* Terminate beacon sync after a single run target is reached
why:
Stops doing useless polling (typically when there is no RPC available)
* Remove crufty comments
* Tighten state reload condition when resuming
why:
Some pathological case might apply if the syncer is stopped while the
distance between finalised block and head is very large and the FCU
base becomes larger than the locked finalised state.
* Verify that finalised number from CL is at least FCU base number
why:
The FCU base number is determined by the database, non zero if
manually imported. The finalised number is passed via RPC by the CL
node and will increase over time. Unless fully synced, this number
will be pretty low.
On the other hand, the FCU call `forkChoice()` will eventually fail
if the `finalizedHash` argument refers to something outside the
internal chain starting at the FCU base block.
* Remove support for completing interrupted sync without RPC support
why:
Simplifies start/stop logic
* Rmove unused import
* Update comments & logs
* Do not start beacon sync unless there is possibly something to do
why:
It would continue polling without having any effect other than
logging. Now it will not start unless there is RPC available
or there was a previously interrupted sync to be resumed.
* Accept finalised hash from RPC with the canon header as well
* Reorg internal sync descriptor(s)
details:
Update target from RPC to provide the `consensus header` as well as
the `finalised` block number
why:
Prepare for using `importBlock()` instead of `persistBlocks()`
* Cosmetic updates
details:
+ Collect all pretty printers in `helpers.nim`
+ Remove unused return codes from function prototype
* Use `importBlock()` + `forkChoice()` rather than `persistBlocks()`
* Update logging and metrics
* Update docu
* Remove `--sync-mode` option from nimbus config
why:
Currently there is only one sync mode available.
* Rename `flare` -> `beacon`, but not base module folder and nim source
why:
The name `flare` was used do designate an alternative `beacon` mode that.
Leaving the base folder and source as-is for a moment, makes it easier
to read change diffs.
* Rename `flare` base module folder and nim source: `flare` -> `beacon`
* Wiring ForkedChainRef to other components
- Disable majority of hive simulators
- Only enable pyspec_sim for the moment
- The pyspec_sim is using a smaller RPC service wired to ForkedChainRef
- The RPC service will gradually grow
* Addressing PR review
* Fix test_beacon/setup_env
* Enable consensus_sim (#2441)
* Enable consensus_sim
* Remove isFile check
* Enable Engine API jwt auth tests and exchange cap tests
* Enable engine api in build_sim.sh
* Wire ForkedChainRef to Engine API newPayload
* Wire Engine API getBodies to ForkedChainRef
* Wire Engine API api_forkchoice to ForkedChainRef
* Wire more RPC methods to ForkedChainRef
* Implement eth_syncing
* Implement eth_call and eth_getlogs
* TxPool: simplify smartHead
* Fix smartHead usage
* Fix txpool headDiff
* Remove hasBlockHeader and use headerExists
* Addressing review
* bump metrics
* Remove cruft
* Cosmetics, update some logging, noise control
* Renamed `CoreDb` function `hasKey` => `hasKeyRc` and provided `hasKey`
why:
Currently, `hasKey` returns a `Result[]` rather than a `bool` which
is what one would expect from a function prototype of this name.
This was a bit of an annoyance and cost unnecessary attention.
* Bump nim-eth, nim-web3, nimbus-eth2
- Replace std.Option with results.Opt
- Fields name changes
* More fixes
* Fix Portal stream async raises and portal testnet Opt usage
* Bump eth + nimbus-eth2 + more fixes related to eth_types changes
* Fix in utp test app and nimbus-eth2 bump
* Fix test_blockchain_json rebase conflict
* Fix EVMC block_timestamp conversion plus commentary
