* extract unused clique/mining support into separate file
why:
mining is currently unsupported by nimbus
* Replay first 51840 transactions from Goerli block chain
why:
Currently Goerli is loaded but the block headers are not verified.
Replaying allows real data PoA development.
details:
Simple stupid gzipped dump/undump layer for debugging based on
the zlib module (no nim-faststream support.)
This is a replay running against p2p/chain.persistBlocks() where
the data were captured from.
* prepare stubs for PoA engine
* split executor source into sup-modules
why:
make room for updates, clique integration should go into
executor/update_poastate.nim
* Simplify p2p/executor.processBlock() function prototype
why:
vmState argument always wraps basicChainDB
* split processBlock() into sub-functions
why:
isolate the part where it will support clique/poa
* provided additional processTransaction() function prototype without _fork_ argument
why:
with the exception of some tests, the _fork_ argument is always derived
from the other prototype argument _vmState_
details:
similar situation with makeReceipt()
* provide new processBlock() version explicitly supporting PoA
details:
The new processBlock() version supporting PoA is the general one also
supporting non-PoA networks, it needs an additional _Clique_ descriptor
function argument for PoA state (if any.)
The old processBlock() function without the _Clique_ descriptor argument
retorns an error on PoA networgs (e.g. Goerli.)
* re-implemented Clique descriptor as _ref object_
why:
gives more flexibility when moving around the descriptor object
details:
also cleaned up a bit the clique sources
* comments for clarifying handling of Clique/PoA state descriptor
* continue importing rlp blocks
why:
a chain of blocks to be imported might have legit blocks
after rejected blocks
details:
import loop only stops if the import list is exhausted or if there
was a decoding error. this adds another four to the count of successful
no-hive tests.
* verify DAO marked extra data field in block header
why:
was ignored, scores another two no-hive tests
* verify minimum required difficulty in header validator
why:
two more nohive tests to succeed
details:
* subsumed extended header tests under validateKinship() and renamed it
more appropriately validateHeaderAndKinship()
* enhanced readability of p2p/chain.nim
* cleaned up test_blockchain_json.nim
* verify positive gasUsed unless no transactions
why:
solves another to nohive tests
details:
straightened test_blockchain_json chech so there is no unconditional
rejection anymore (based on the input test scenario)
why:
some handy features were intended to support the unit test from
the clique/clique_test.go source (the other one is from
clique/snapshot_test.go.)
as this test cannot realistically be implemented without the full
api (includes mining support), it is left as that
The precompile fixture tests (`test_precompiles.nim`) are now incompatible with
ENABLE_EVMC=1, because `noTransfer` does not work with the new EVMC path.
This will start working again after the host/EVM context rework (needed for
other reasons anyway), but for now disable these tests so that other work can
continue.

The common forks list was already used, redirected via `vm_forks` for
historical compatibility. Remove the old `vm_forks` now and divert all imports
to the common forks list outside the EVM.

Fork names were originally capitalized, and were made lower case by @narimiran
in commit 36a7519 to satisfy `parseEnum` in some tests. Restore the
capitalization and make the tests work with it.

The rationale in EIP-6[1] for changing names to `selfDestruct` applies to code
as much as it does to specs. Also, Ethereum uses the new names consistently,
so it's useful for our code to match the terms used in later EIP specs and
testsuite entries.
This change is straightforward, and is a prerequisite for patches to come that
do things with the `selfDestruct` fields.

The conditions mentioned in the old TODO comment have been checked. All
fixtures have either 40 hex digits or empty string for "to". There is a test
with all-zeros, and it means send to that account, not contract creation.
Empty string means contract creation.
This patch does not change the relaxed parsing where fewer than 40 digits is
accepted. We should probably be stricter about this.

why:
previously, table data were stored with the table iterator. while
loading a table with permuted entries will always reconstruct equivalent
tables (in the sense of `==`), serialisation data are not comparable.
this patch produces always the same serialised data for equivalent
tables.
why:
source-local unit tests would hardly be triggered by github CI as rightly
criticised with the last patch.
details:
source-local unit tests have been moved to tests folder.
this version also contains rlp serialisation code so rlp encode/decode
will apply tranparently. this is not needed in p2p/validate but will be
useful with the clique protocol.
after EIP2718/EIP2930, we have additional fields:
type AccessTuple {
address: Address!
storageKeys : [Bytes32!]
}
type Transaction {
r: BigInt!
s: BigInt!
v: BigInt!
# Envelope transaction support
type: Int
accessList: [AccessTuple!]
}

when a skipped test case not in the skip list
but skipped using `testStatusIMPL`, the generated
markdown file list it as failed.
now that bug is fixed.
now test_blockchain_json is using block validation code
from p2p/executor.nim instead of using it's own
block validation code.
this will reduce maintenance cost and fixes#592.
instead of using it's own blockNumber to Fork calculation,
we switch to ChainConfig to Fork to ensure smooth transition
when using common block validator.
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
Move the EVM setup and call in precompile tests to `fixtureCallEvm` in
`call_evm`. Extra return values needed for testing are returned specially, and
the convention for reporting gas used is changed to match `asmCallEvm`.
Although the precompile tests used `execPrecompiles` before, `executeOpcodes`
does perfectly well as a substitute, allowing `fixtureCallEvm` to be shared.
_Significantly, this patch also makes `Computation` more or less an internal
type of the EVM now._
Nothing outside the EVM (except `call_evm`) needs access any more to
`Computation`, `execComputation`, `executeOpcodes` or `execPrecompiles`.
Many imports can be trimmed, some files removed, and EVMC is much closer.
(As a bonus, the functions in `call_evm` reveal what capabilities parts of the
program have needed over time, makes certain bugs and inconsistencies clearer,
and suggests how to refactor into a more useful shared entry point.)

Move the EVM setup and call in fixtures "vm json tests" to new function
`fixtureCallEvm` in `call_evm`. Extra return values needed for testing are
returned specially.
This entry point is different from all other `..CallEvm` type functions,
because it uses `executeOpcodes` instead of `execComputation`, so it doesn't
update the account balance or nonce on entry and exit from the EVM.
The new code is a bit redundant and simplistic intentionally, as the purpose is
to move functionality to `call_evm` with high confidence nothing really
changed. The calls will be jointly refactored afterwards to merge differences.

In the `text_vm_json` ("fixtures") test code, there is another variant of
`rpcSetupComputation` and `txSetupComputation` with slightly different
paremeters. The similarity is obvious.
It is a special setup for testing, though, as it requires slightly different
parameters.

usually, there is always a sender around `getRecipient` call.
no need to recalculate sender. and more important, in some of
JSON-RPC/GraphQL call, the sender is come from `rpcCallData`,
not from `tx.getSender`. or in ohter situation when the tx is
an unsigned tx, without `r,s,v` fields to calculate sender.
Move the EVM setup and call in `macro_assembler` (`runVM`) entirely to new
function `asmCallEvm` in `call_evm`. Extra return values needed for

The second `asmSetupComputation looks up state by block number and preceding

In the `macro_assembler` test code, `initComputation` is another variant of
`rpcSetupComputation` and `txSetupComputation` with slightly different
paremeters. The similarity is obvious.
It is a special setup for testing, though, as it requires a contract-creation
transaction for parameters, but sets up a `CALL` execution not `CREATE`.
Gather this into `call_evm`: `initComputation` -> `asmSetupComputation`.

disableParamFiltering() is called in test_all, so its ok when
called via test_all. but when test_generalstate_json or
test_blockchain_json is called independently, and we are using
command line switch, the default param handler from std/unittest
will interfere. hence need to disable it.
The "new block chain json tests" were being skipped on Linux, but silently so
that CI didn't notice. These are a significant part of the Ethereum test suite.
See the missing output from `make test`, also visible in CI logs for Linux
targets (prior to this commit):
[OK] tests/fixtures/eth_tests/TransactionTests/ttGasPrice/TransactionWithGasPriceOverflow.json
[OK] tests/fixtures/eth_tests/TransactionTests/ttGasPrice/TransactionWithHighGasPrice.json
[Suite] new block chain json tests
<-- nothing here
[Suite] Fork ID tests
[OK] MainNet
[OK] RopstenNet
Commit 3d468a7 (`fixes path pointing to eth_tests`) renamed the JSON fixture
source directoryf in the witness-builder tests but not the regular blockchain
tests. As a result, searching for JSON test files yielded zero results. To
make this less likely in future, zero results is now an error.
