Includes a simple test harness for the merge interop M1 milestone
This aims to enable connecting nimbus-eth2 to nimbus-eth1 within
the testing protocol described here:
https://github.com/status-im/nimbus-eth2/blob/amphora-merge-interop/docs/interop_merge.md
To execute the work-in-progress test, please run:
In terminal 1:
tests/amphora/launch-nimbus.sh
In terminal 2:
tests/amphora/check-merge-test-vectors.sh
- Remove the `--evm` option on non-EVMC builds.
`when` around an option doesn't work with confutils; it fails to compile.
Workaround that by setting the `ignore` pragma on EVMC-specific options.
(Thanks @jangko for that new pragma). I prefer this to a solution which
moves the whole option's pragma elsewhere, especially if we add more options.
- Improve the help text, so that it shows the standard library extension on
each target platform (or none if on another platform).
- Undo b3f21bf4 "add missing evmc_enabled conditional compilation in
evmc_dynamic_loader". Move the conditional to `nimbus.nim`, and take more
care there to only use the loader function in EVMC builds.
It's ok to just not include this EVMC-only module (like some other EVMC
modules), rather than making the module itself a bit broken: Without this
change, it references a function that's not imported or linked to, and it
only links because there is no call sequence reaching that function.

- `network` and `discovery` got additional longDesc,
the help text now become more descriptive.
- `networkId` and `networkParams` now is ignored by confutils
and become ordinary fields of NimbusConf.
This patch adds:
- Load and use a third-party EVM in a shared library, instead of Nimbus EVM.
- New option `--evm` to specify which library to load.
- The library and this loader conforms to the [EVMC]
(https://evmc.ethereum.org/) 9.x specification.
Any third-party EVM which is compatible with EVMC version 9.x and supports EVM1
contract code will be accepted. The operating system's shared library format
applies. These are `.so*` files on Linux, `.dll` files on Windows and `.dylib`
files on Mac.
The alternative EVM can be selected in two ways:
- Nimbus command line option `--evm:<path>`.
- Environment variable `NIMBUS_EVM=<path>`.
The reason for an environment variable is this allows all the test programs to
run with a third-party EVM as well. Some don't parse command line options.
There are some limitations to be aware of:
- The third-party EVM must use EVMC version 9.x, no other major version.
EVMC 9.x supports EIP-1559 / London fork and older transactions.
- Nested `*CALL` and `CREATE*` operations don't use the third-party EVM yet.
These call the built-in Nimbus EVM. This mixing of different EVMs between
levels is explicitly allowed in specs, so there is no problem doing it.
- The third-party EVM doesn't need to support precompiles, because those are
nested calls, which use the built-in Nimbus EVM.
- Third-party EVMs execute contracts correctly, but fail the final `rootHash`
match. The reason is that some account state changes, which are correct, are
currently inside the Nimbus EVM and need to be moved to EVMC host logic.
*This is a known work in progress*. The EVM execution itself is fine.
Test results using "evmone" third-party EVM:
- [evmone](https://github.com/ethereum/evmone) has been tested. Only on
Linux but it "should" work on Windows and Mac equally well.
- [Version 0.8.1](https://github.com/ethereum/evmone/releases/tag/v0.8.1) was
used because it is compatible with EVMC 9.x, which is required for the
EIP-1559 / London fork, which Nimbus supports. Version 0.8.0 could be used
but it looks like an important bug was fixed in 0.8.1.
- evmone runs fine and the trace output looks good. The calls and arguments
are the same as the built-in Nimbus EVM for tests that have been checked
manually, except evmone skips some calls that can be safely skipped.
- The final `rootHash` is incorrect, due to the *work in progress* mentioned
above which is not part of the evmone execution. Due to this, it's possible
to try evmone and verify expected behaviours, which also validates our own
EVMC implementation, but it can't be used as a full substitute yet.

this is a preparation for migration to confutils based config
although there is still some getConfiguration usage in tests code
it will be removed after new config arrived
although they are technically different, but in reality,
many networks are using the same id for ChainId dan NetworkId.
in this commit, we set networkid from config file's chainId.
- allow clique period and epoch to be configured via config file
- this also activate poaEngine mode
- remove clique period configuration from cli to reduce confusion
- fix#786
new command line options:
--ws Enable the Websocket JSON-RPC server
--wsbind:<value> Set address:port pair(s) (comma-separated) Websocket JSON-RPC server will bind to (default: localhost:8546)
--wsapi:<value> Enable specific set of Websocket RPC API from list (comma-separated) (available: eth, debug)
fixes#770
new command line options:
--clique-period:<value> Enables clique support. value is block time in seconds
--engine-signer:<value> Enables mining. value is EthAddress in hex
--import-key:<path> Import unencrypted 32 bytes hex private key file
fixes#771
* Provide API
details:
API is bundled via clique.nim.
* Set extraValidation as default for PoA chains
why:
This triggers consensus verification and an update of the list
of authorised signers. These signers are integral part of the
PoA block chain.
todo:
Option argument to control validation for the nimbus binary.
* Fix snapshot state block number
why:
Using sub-sequence here, so the len() function was wrong.
* Optional start where block verification begins
why:
Can speed up time building loading initial parts of block chain. For
PoA, this allows to prove & test that authorised signers can be
(correctly) calculated starting at any point on the block chain.
todo:
On Goerli around blocks #193537..#197568, processing time increases
disproportionally -- needs to be understand
* For Clique test, get old grouping back (7 transactions per log entry)
why:
Forgot to change back after troubleshooting
* Fix field/function/module-name misunderstanding
why:
Make compilation work
* Use eth_types.blockHash() rather than utils.hash() in Clique modules
why:
Prefer lib module
* Dissolve snapshot_misc.nim
details:
.. into clique_verify.nim (the other source file clique_unused.nim
is inactive)
* Hide unused AsyncLock in Clique descriptor
details:
Unused here but was part of the Go reference implementation
* Remove fakeDiff flag from Clique descriptor
details:
This flag was a kludge in the Go reference implementation used for the
canonical tests. The tests have been adapted so there is no need for
the fakeDiff flag and its implementation.
* Not observing minimum distance from epoch sync point
why:
For compiling PoA state, the go implementation will walk back to the
epoch header with at least 90000 blocks apart from the current header
in the absence of other synchronisation points.
Here just the nearest epoch header is used. The assumption is that all
the checkpoints before have been vetted already regardless of the
current branch.
details:
The behaviour of using the nearest vs the minimum distance epoch is
controlled by a flag and can be changed at run time.
* Analysing processing time (patch adds some debugging/visualisation support)
why:
At the first half million blocks of the Goerli replay, blocks on the
interval #194854..#196224 take exceptionally long to process, but not
due to PoA processing.
details:
It turns out that much time is spent in p2p/excecutor.processBlock()
where the elapsed transaction execution time is significantly greater
for many of these blocks.
Between the 1371 blocks #194854..#196224 there are 223 blocks with more
than 1/2 seconds execution time whereas there are only 4 such blocks
before and 13 such after this range up to #504192.
* fix debugging symbol in clique_desc (causes CI failing)
* Fixing canonical reference tests
why:
Two errors were introduced earlier but ovelooked:
1. "Remove fakeDiff flag .." patch was incomplete
2. "Not observing minimum distance .." introduced problem w/tests 23/24
details:
Fixing 2. needed to revert the behaviour by setting the
applySnapsMinBacklog flag for the Clique descriptor. Also a new
test was added to lock the new behaviour.
* Remove cruft
why:
Clique/PoA processing was intended to take place somewhere in
executor/process_block.processBlock() but was decided later to run
from chain/persist_block.persistBlock() instead.
* Update API comment
* ditto
This preparation is needed for subsequent
EIPs included in London.
- Add London to Fork enum
- Block number to fork
- Parsing London fork in chain config
- Prepare gas costs table for London
- Prepare EVM opcode dispatcher for London
- Block rewards for London
- Prepare hive script for London
File `vm_types2` is obsolete. Remove this file and divert all imports to the
common forks list outside the EVM, or in some cases they don't need it anyway.

This is the main patch which removes Whisper code from `nimbus-eth1` code.
It removes all configuration, help, startup, JSON-RPC calls and most types.
Note, there is still Whisper functionality in `nim-eth`. Also, the "wrapper"
under `wrappers/` isn't dealt with by this change, but it's not built by
default (and might not currently work).

This commit turns Whisper off by default, without changing anything else.
So this can be cherry-picked if you just want to disable Whisper without
removing it.

instead of using stdlib/json, now we switch to json_serialization
the result is much tidier code and more robust when parsing
optional fields.
fixes#635
the `processArguments` now have overloaded proc, one with opt param and one without.
the OptParser now can be passed to `opt` param.
this is useful in scenario where in test code we need to simulate something
without using real command line arguments.
rather than initialize it to 0, those block numbers
are initialized to high(BlockNumber). this will fix
issue when imported genesis.json doesn't contains all
forks' blockNumber.
Capitalisation:
- The option is lower case `--logmetrics` but help said `--logMetrics`
- Same for `--logmetricsiterval`
- Same for `--metricsserver` and `--metricsserverport`
Ethereum network selection:
- Moved out into their own, cleaner help section
- Added help for `--mainnet`, `--goerli` and `--kovan`
- Moved `--networkid` and `--customnetwork` to this section as well
Other:
- Reworded or formatted some help lines for clarity and consistency
Changed options:
- Renamed `--metricserver` to `--metrics`
- Renamed `--matricsserverport` to `--metricsport`
- Removed Morden network; this didn't have an option, but could be
selected with `--networkid:2` and then fail to work

* switch to chronos metrics, remove insecure
See https://github.com/status-im/nimbus-eth2/pull/2468
also fixes pcre linking for real, and adds some random build flags that
help nimbus-eth2 stay afloat
* fix help
* don't omit frame pointers on windows
