This PR extends the Hooks interface with a new method,
`OnSystemCallStartV2`, which takes `VMContext` as its parameter.
Motivation
By including `VMContext` as a parameter, the `OnSystemCallStartV2` hook
achieves parity with the `OnTxStart` hook in terms of provided insights.
This alignment simplifies the inner tracer logic, enabling consistent
handling of state changes and internal calls within the same framework.

This PR refactors the structlog a bit, making it so that it can be used
in a streaming mode.
-------------
OBS: this PR makes a change in the input `config` config, the third
input-parem field to `debug.traceCall`. Previously, seteting it to e.g.
` {"enableMemory": true, "limit": 1024}` would mean that the response
was limited to `1024` items. Since an 'item' may include both memory and
storage, the actual size of the response was undertermined.
After this change, the response will be limited to `1024` __`bytes`__
(or thereabouts).
-----------
The commandline usage of structlog now uses the streaming mode, leaving
the non-streaming mode of operation for the eth_Call.
There are two benefits of streaming mode
1. Not have to maintain a long list of operations,
2. Not have to duplicate / n-plicate data, e.g. memory / stack /
returndata so that each entry has their own private slice.

Lots of packages depend on eth/downloader just for the SyncMode type.
Since we have a dedicated package for eth protocol configuration, it
makes more sense to define SyncMode there, turning eth/downloader into
more of a leaf package.
This flag is very rarely needed, so it's OK for it to have a verbose
name. The name --trace also conflicts with the concept of EVM tracing,
which is much more heavily used.
The fuzzer added recenly to fuzz the eth handler doesn't
build on oss-fuzz, because it also has dependencies in the peer_test.go.
This change fixes it, I hope, by adding that file also for preprocessing.
* unify `staterunner` and `blockrunner` CLI flags, especially around
tracing
* added support for struct logger or json logging (although having issue
#30658)
* new --cross-check flag to validate the stateless witness collection
/ execution matches stateful
* adds support for tracing the stateless execution when a tracer is set
(to more easily debug differences)
* --human for more readable test summary
* directory or file input, so if you pass tests/spec-tests/fixtures/blockchain_tests it will execute all
blockchain tests
When a tx/block was being traced through the API the state hooks weren't
being called as they should. This is due to #30745 moving the hooked
statedb one level up in the state processor. This PR fixes that.

This change relocates the EVM tx context switching to the ApplyMessage function.
With this change, we can remove a lot of EVM.SetTxContext calls before
message execution.
### Tracing API changes
- This PR replaces the `GasPrice` field of the `VMContext` struct with
`BaseFee`. Users may instead take the effective gas price from
`tx.EffectiveGasTipValue(env.BaseFee)`.

This PR introduces a `ContractCodeReader` interface with functions defined:
type ContractCodeReader interface {
Code(addr common.Address, codeHash common.Hash) ([]byte, error)
CodeSize(addr common.Address, codeHash common.Hash) (int, error)
}
This interface can be implemented in various ways. Although the codebase
currently includes only one implementation, additional implementations
could be created for different purposes and scenarios, such as a code
reader designed for the Verkle tree approach or one that reads code from
the witness.
*Notably, this interface modifies the function’s semantics. If the
contract code is not found, no error will be returned. An error should
only be returned in the event of an unexpected issue, primarily for
future implementations.*
The original state.Reader interface is extended with ContractCodeReader
methods, it gives us more flexibility to manipulate the reader with additional
logic on top, e.g. Hooks.
type Reader interface {
ContractCodeReader
StateReader
}

This pull request ports some changes from the main state snapshot
integration one, specifically introducing the flat state tracking in
pathdb.
Note, the tracked flat state changes are only held in memory and won't
be persisted in the disk. Meanwhile, the correspoding state retrieval in
persistent state is also not supported yet. The states management in
disk is more complicated and will be implemented in a separate pull
request.
Part 1: https://github.com/ethereum/go-ethereum/pull/30752
The existing implementation is correct when building and verifying
blocks, since we will only collect non-empty requests into the block
requests list.
But it isn't correct for cases where a requests list containing empty
items is sent by the consensus layer on the engine API. We want to
ensure that empty requests do not cause a difference in validation
there, so the commitment computation should explicitly skip them.
Since we don't really support custom networks anymore, we don't need the
bootnode utility. In case a discovery-only node is wanted, it can still be run using cmd/devp2p.
This workaround is meant to minimize the possibility for snapshot generation
once the geth node upgrades to new version (specifically #30752 )
In #30752, the journal format in state snapshot is modified by removing
the destruct set. Therefore, the existing old format (version = 0) will be
discarded and all in-memory layers will be lost. Unfortunately, the lost
in-memory layers can't be recovered by some other approaches, and the
entire state snapshot will be regenerated (it will last about 2.5 hours).
This pull request introduces a workaround to adopt the legacy journal if
the destruct set contained is empty. Since self-destruction has been
deprecated following the cancun fork, the destruct set is expected to be nil for
layers above the fork block. However, an exception occurs during contract
deployment: pre-funded accounts may self-destruct, causing accounts with
non-zero balances to be removed from the state. For example,
https://etherscan.io/tx/0xa087333d83f0cd63b96bdafb686462e1622ce25f40bd499e03efb1051f31fe49).
For nodes with a fully synced state, the legacy journal is likely compatible with
the updated definition, eliminating the need for regeneration. Unfortunately,
nodes performing a full sync of historical chain segments or encountering
pre-funded account deletions may face incompatibilities, leading to automatic
snapshot regeneration.
Reusing state between benchmark iterations resulted in inconsistent
results across runs, which surfaced in https://github.com/ethereum/go-ethereum/issues/30778 .
If these errors are triggered again, they will now trigger panic.

This reverts commit 23800122b3.
The original pull request introduces a bug and some flaky tests are
detected because of this flaw.
```

Before the original PR, the snapshot would block the function until the
disk layer
was fully generated under the following conditions:
(a) explicitly required by users with `AsyncBuild = false`.
(b) the snapshot was being fully rebuilt or *the disk layer generation
had resumed*.
Unfortunately, with the changes introduced in that PR, the snapshot no
longer waits
for disk layer generation to complete if the generation is resumed. It
brings lots of
uncertainty and breaks this tiny debug feature.
This updates the message you get when trying to initialize Geth with
genesis.json that doesn't have `terminalTotalDifficulty`. The previous
message was a bit obscure, I had to check the code to find out what the
problem was.
This PR is purely for improved readability; I was doing work involving
the file and think this may help others who are trying to understand
what's going on.
1. `snapshot.Tree.Rebuild()` now returns a function that blocks until
regeneration is complete, allowing `Tree.waitBuild()` to be removed
entirely as all it did was search for the `done` channel behind this new
function.
2. Its usage inside `New()` is also simplified by (a) only waiting if
`!AsyncBuild`; and (b) avoiding the double negative of `if !NoBuild`.

#28764 updated `func MakeTopics` to support negative `*big.Int`s.
However, it also changed the behavior of the function from just
_reading_ the input `*big.Int` via `Bytes()`, to leveraging
`big.U256Bytes` which is documented as being _destructive_:
This change updates `MakeTopics` to not mutate the original, and
also applies the same change in signer/core/apitypes.
This PR improves the output of the markdown logger a bit.
- Remove `RStack` field,
- Move `Stack` last, since it may have very large vertical expansion
- Make the pre- and post-exec metadata structured into a bullet-list
This change fixes a bug on the `DirectoryFlag` and the `BigFlag`, which would trigger a `panic` with the message "flag redefined" in case an alias was added to such a flag.
This pull request removes the destruct flag from the state snapshot to
simplify the code.
Previously, this flag indicated that an account was removed during a
state transition, making all associated storage slots inaccessible.
Because storage deletion can involve a large number of slots, the actual
deletion is deferred until the end of the process, where it is handled
in batches.
With the deprecation of self-destruct in the Cancun fork, storage
deletions are no longer expected. Historically, the largest storage
deletion event in Ethereum was around 15 megabytes—manageable in memory.
In this pull request, the single destruct flag is replaced by a set of
deletion markers for individual storage slots. Each deleted storage slot
will now appear in the Storage set with a nil value.
This change will simplify a lot logics, such as storage accessing,
storage flushing, storage iteration and so on.
This pull request refactors the EVM constructor by removing the
TxContext parameter.
The EVM object is frequently overused. Ideally, only a single EVM
instance should be created and reused throughout the entire state
transition of a block, with the transaction context switched as needed
by calling evm.SetTxContext.
Unfortunately, in some parts of the code, the EVM object is repeatedly
created, resulting in unnecessary complexity. This pull request is the
first step towards gradually improving and simplifying this setup.

In many cases, there is a need to create somewhat nontrivial bytecode. A
recent example is the verkle statetests, where we want a `CREATE2`- op
to create a contract, which can then be invoked, and when invoked does a
selfdestruct-to-self.
It is overkill to go full solidity, but it is also a bit tricky do
assemble this by concatenating bytes. This PR takes an approach that
has been used in in goevmlab for several years.
Using this utility, the case can be expressed as:
```golang
// Some runtime code
runtime := program.New().Ops(vm.ADDRESS, vm.SELFDESTRUCT).Bytecode()
// A constructor returning the runtime code
initcode := program.New().ReturnData(runtime).Bytecode()
// A factory invoking the constructor
outer := program.New().Create2AndCall(initcode, nil).Bytecode()
```
We have a lot of places in the codebase where we concatenate bytes, cast
from `vm.OpCode` . By taking tihs approach instead, thos places can be made a
bit more maintainable/robust.
