This PR contains 3 fixes for interaction between the Bor mining loop and
the TX pool which where causing the regular creation of blocks with zero
transactions.
* Mining/Tx pool block synchronization
The synchronization of the tx pool between the sync loop and the mining
loop has been changed so that both are triggered by the same event and
synchronized via a sync.Cond rather than a polling loop with a hard
coded loop limit. This means that mining now waits for the pool to be
updated from the previous block before it starts the mining process.
* Txpool Startup consolidated into its MainLoop
Previously the tx pool start process was dynamically triggered at
various points in the code. This has all now been moved to the start of
the main loop. This is necessary to avoid a timing hole which can leave
the mining loop hanging waiting for a previously block broadcast which
it missed due to its delay start.
* Mining listens for block broadcast to avoid duplicate mining
operations
The mining loop for bor has a recommit timer in case blocks re not
produced on time. However in the case of sprint transitions where the
seal publication is delayed this can lead to duplicate block production.
This is suppressed by introducing a `waiting` state which is exited upon
the block being broadcast from the sealing operation.
Mdbx now takes a logger - but this has not been pushed to all callers -
meaning it had an invalid logger
This fixes the log propagation.
It also fixed a start-up issue for http.enabled and txpool.disable
created by a previous merge
* fix "genesis hash does not match" when dev nodes connect
The "dev" nodes need to have the same --miner.etherbase in order to
generate the same genesis ExtraData by DeveloperGenesisBlock(). Override
DevnetEtherbase global var that's used if --miner.etherbase is not
passed. (for NonBlockProducer case)
* fix missing private key for the hardcoded DevnetEtherbase
Fixes panic if SigKey is not found. Bor non-producers will use a default
`DevnetEtherbase` while Dev nodes modify it. Save hardcoded
DevnetEtherbase/DevnetSignPrivateKey into accounts so that SigKey can
recover it.
* refactor devnet.node to contain Node config
This avoids interface{} type casts and fixes an error with
Heimdall.validatorSet == nil
* add connection retries to rpcCall and Subscribe of requestGenerator
Fixes "connection refused" errors due to node not ready to handle early
RPC requests.
* fix deadlock in Heimdall.NodeStarted
* fix GetBlockByNumber
Fixes "cannot unmarshal string into Go struct field body.transactions of
type jsonrpc.RPCTransaction"
* demote "no of blocks on childchain is less than confirmations
required" to Info (#8626)
* demote "mismatched pending subpool size" to Debug (#8615)
* revert wiggle testing code
This request is extending the devnet functionality to more fully handle
contract processing by adding support for the following calls:
* trace_call,
* trace_transaction
* debug_accountAt,
* eth_getCode
* eth_estimateGas
* eth_gasPrice
It also contains an initial rationalization of the devnet subscription
code to use the erigon client code directly rather than using its own
intermediate subscription management.
This is used to implement a general purpose block waiter - which can be
used in any scenario step - rather than being specific to transaction
processing.
This pull also contains an end to end tested sync processor for bor and
associated support services:
* Heimdall (supports sync event transfer)
* Faucet - allows the creation and funding of arbitary test specific
accounts (cross chain)
Notes and Caveats:
* Code generation for contracts requires `--evm-version paris`. For
chains which don't support push0 for solc over 0.8.19
* The bor log processing post the application of sync events causes a
panic - this will be the subject of a seperate smaller push as it is not
devnet specific
* The bor code seems to make repeated calls for the same sync events and
also reverts requests - this needs further investigation. This is the
behaviour of the current implementation and may be required - although
it does seem to generate repeat processing - which could be avoided.
This request implements an end to end Polygon state sync in the devnet.
It does this by deploying smart contracts ont the L2 & L2 chain which
follow the polygon fx portal model with security checks removed to
simplify the code. The sync events generated are routed through a local
mock heimdal - to avoid the consensus process for testing purposes.
The commit also includes support code to help the delivery of additional
contract based scenratios.
An update to the devnet to introduce a local heimdall to facilitate
multiple validators without the need for an external process, and hence
validator registration/staking etc.
In this initial release only span generation is supported.
It has the following changes:
* Introduction of a local grpc heimdall interface
* Allocation of accounts via a devnet account generator ()
* Introduction on 'Services' for the network config
"--chain bor-devnet --bor.localheimdall" will run a 2 validator network
with a local service
"--chain bor-devnet --bor.withoutheimdall" will sun a single validator
with no heimdall service as before
