* Cosmetics
* Must not async wait inside termination `for` loop
why:
Async-waiting inside a `for` loop will switch to temination process
which uncontrollably will modify the for-loop data base.
* Avoid `waitFor` in scheduler termination code
why:
Is reserved for main loop
* 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.
* 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`
* Block header download starting at Beacon down to Era1
details:
The header download implementation is intended to be completed to a
full sync facility.
Downloaded block headers are stored in a `CoreDb` table. Later on they
should be fetched, complemented by a block body, executed/imported,
and deleted from the table.
The Era1 repository may be partial or missing. Era1 headers are neither
downloaded nor stored on the `CoreDb` table.
Headers are downloaded top down (largest block number first) using the
hash of the block header by one peer. Other peers fetch headers
opportunistically using block numbers
Observed download times for 14m `MainNet` headers varies between 30min
and 1h (Era1 size truncated to 66m blocks.), full download 52min
(anectdotal.) The number of peers downloading concurrently is crucial
here.
* Activate `flare` by command line option
* Fix copyright year
* 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
* Attempt to roll back stateless mode implementation in a single PR
why:
+ Stateless mode is not fully working and in the way
+ Single PR should make it feasible to investigate for a possible
re-implementation
* Fix copyright year
* Fix annotation for exception (evmc mode)
