This change fixes is a rare bug in test generator: If the run is very unlucky it
can use `modifyAccountOp` / `deleteAccountOp` without creating any
account, leading to have a trie root same as the parent.
This change makes the first operation always be a creation.
This commit makes it so that the struct logger will not emit logs while
system calls are being executed. This will make it consistent with
the JSON and MD loggers. It is as it stands hard to distinguish when
system calls are being processed vs when a tx is being processed.

Here I am proposing two small changes to the exported API for EIP-7702:
(1) `Authorization` has a very generic name, but it is in fact only used
for one niche use case: authorizing code in a `SetCodeTx`. So I propose
calling it `SetCodeAuthorization` instead. The signing function is
renamed to `SignSetCode` instead of `SignAuth`.
(2) The signing function for authorizations should take key as the first
parameter, and the authorization second. The key will almost always be
in a variable, while the authorization can be given as a literal.
This fixes a regression introduced recently. Without this fix, it's not
possible to use statetests without `.json` suffix. This is problematic for
goevmlab `minimizer`, which appends the suffix `.min` during processing.
Fixing some issues I found while regenerating RPC tests for Prague:
- Authorization signature values were not encoded as hex
- `requestsRoot` in block should be `requestsHash`
- `authorizationList` should work for `eth_call`
Noticed this omission while doing some work on goevmlab. We don't
properly type some of the opcodes, but apparently implicit casting works
in all the internal usecases.
Adding some missing functionality I noticed while updating the hivechain
tool for the Prague fork:
- we forgot to process the parent block hash
- added `ConsensusLayerRequests` to get the requests list of the block
This change adds methods which makes it possible for to wait for a transaction with a specific hash when deploying contracts during abi bind interaction.

In this pull request, the state iterator is implemented. It's mostly a copy-paste
from the original state snapshot package, but still has some important changes
to highlight here:
(a) The iterator for the disk layer consists of a diff iterator and a disk iterator.
Originally, the disk layer in the state snapshot was a wrapper around the disk,
and its corresponding iterator was also a wrapper around the disk iterator.
However, due to structural differences, the disk layer iterator is divided into
two parts:
- The disk iterator, which traverses the content stored on disk.
- The diff iterator, which traverses the aggregated state buffer.
Checkout `BinaryIterator` and `FastIterator` for more details.
(b) The staleness management is improved in the diffAccountIterator and
diffStorageIterator
Originally, in the `diffAccountIterator`, the layer’s staleness had to be checked
within the Next function to ensure the iterator remained usable. Additionally,
a read lock on the associated diff layer was required to first retrieve the account
blob. This read lock protection is essential to prevent concurrent map read/write.
Afterward, a staleness check was performed to ensure the retrieved data was
not outdated.
The entire logic can be simplified as follows: a loadAccount callback is provided
to retrieve account data. If the corresponding state is immutable (e.g., diff layers
in the path database), the staleness check can be skipped, and a single account
data retrieval is sufficient. However, if the corresponding state is mutable (e.g.,
the disk layer in the path database), the callback can operate as follows:
```go
func(hash common.Hash) ([]byte, error) {
dl.lock.RLock()
defer dl.lock.RUnlock()
if dl.stale {
return nil, errSnapshotStale
}
return dl.buffer.states.mustAccount(hash)
}
```
The callback solution can eliminate the complexity for managing
concurrency with the read lock for atomic operation.
This PR implements EIP-7702: "Set EOA account code".
Specification: https://eips.ethereum.org/EIPS/eip-7702
> Add a new transaction type that adds a list of `[chain_id, address,
nonce, y_parity, r, s]` authorization tuples. For each tuple, write a
delegation designator `(0xef0100 ++ address)` to the signing account’s
code. All code reading operations must load the code pointed to by the
designator.

Closes#23210
# Context
When deploying Geth in Kubernetes with ReplicaSets, we encountered two
DNS-related issues affecting node connectivity. First, during startup,
Geth tries to resolve DNS names for static nodes too early in the config
unmarshaling phase. If peer nodes aren't ready yet (which is common in
Kubernetes rolling deployments), this causes an immediate failure:
```
INFO [11-26|10:03:42.816] Starting Geth on Ethereum mainnet...
INFO [11-26|10:03:42.817] Bumping default cache on mainnet provided=1024 updated=4096
Fatal: config.toml, line 81: (p2p.Config.StaticNodes) lookup idontexist.geth.node: no such host
```
The second issue comes up when pods get rescheduled to different nodes -
their IPs change but peers keep using the initially resolved IP, never
updating the DNS mapping.
This PR adds proper DNS support for enode:// URLs by deferring resolution
to connection time. It also handles DNS failures gracefully instead of failing
fatally during startup, making it work better in container environments where
IPs are dynamic and peers come and go during rollouts.

This fixes an issue where the disconnect message was not wrapped in a list.
The specification requires it to be a list like any other message.
In order to remain compatible with legacy geth versions, we now accept both
encodings when parsing a disconnect message.

This PR modifies how the metrics library handles `Enabled`: previously,
the package `init` decided whether to serve real metrics or just
dummy-types.
This has several drawbacks:
- During pkg init, we need to determine whether metrics are enabled or
not. So we first hacked in a check if certain geth-specific
commandline-flags were enabled. Then we added a similar check for
geth-env-vars. Then we almost added a very elaborate check for
toml-config-file, plus toml parsing.
- Using "real" types and dummy types interchangeably means that
everything is hidden behind interfaces. This has a performance penalty,
and also it just adds a lot of code.
This PR removes the interface stuff, uses concrete types, and allows for
the setting of Enabled to happen later. It is still assumed that
`metrics.Enable()` is invoked early on.
The somewhat 'heavy' operations, such as ticking meters and exp-decay,
now checks the enable-flag to prevent resource leak.
The change may be large, but it's mostly pretty trivial, and from the
last time I gutted the metrics, I ensured that we have fairly good test
coverage.

This PR attempts to clean up some ambiguities and quirks from recent
changes to evm flag handling.
This PR mainly focuses on `evm run` subcommand, to use the same flags
for configuring tracing/output options as `statetest/blocktest` does.
Additionally, it adds quite a lot of tests for expected outputs of the
various subcommands, to avoid accidental changes.

It's a pull request based on https://github.com/ethereum/go-ethereum/pull/30643
In this pull request, the partial functional state reader is enabled if **legacy snapshot
is not enabled**. The tracked flat states in pathdb will be used to serve the state
retrievals, as the second implementation to fasten the state access.
This pull request should be a noop change in normal cases.
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.
