827a60e9f8 cmd/geth: add flag to set genesis (#32844)
This PR is an alternative to #32556.

Instead of trying to be smart and reuse `geth init`, we can introduce a
new flag `--genesis` that loads the `genesis.json` from file into the
`Genesis` object in the same path that the other network flags currently
work in.

Question: is something like `--genesis` enough to start deprecating
`geth init`?

--

```console
$ geth --datadir data --hoodi
..
INFO [10-06|22:37:11.202]  - BPO2:                        @1762955544
..
$ geth --datadir data --genesis genesis.json
..
INFO [10-06|22:37:27.988]  - BPO2:                       @1862955544
..
```

Pull the genesis [from the
specs](https://raw.githubusercontent.com/eth-clients/hoodi/refs/heads/main/metadata/genesis.json)
and modify one of the BPO timestamps to simulate a shadow fork.

internal/ethapi: add eth_SendRawTransactionSync (#32830)
New RPC method eth_sendRawTransactionSync(rawTx, timeoutMs?) that
submits a signed tx and blocks until a receipt is available or a timeout
elapses.

Two CLI flags to tune server-side limits:

--rpc.txsync.defaulttimeout (default wait window)

--rpc.txsync.maxtimeout (upper bound; requests are clamped)

eth/filters, cmd: add config of eth_getLogs address limit (#32327)
Add cli configurable limit for the number of addresses allowed in
eth_getLogs filter criteria:
https://github.com/ethereum/go-ethereum/issues/32264
 
 Key changes:
- Added --rpc.getlogmaxaddrs CLI flag (default: 1000) to configure the
maximum number of addresses
- Updated ethconfig.Config with FilterMaxAddresses field for
configuration management
- Modified filter system to use the configurable limit instead of the
hardcoded maxAddresses constant
- Enhanced test coverage with new test cases for address limit
validation
- Removed hardcoded validation from JSON unmarshaling, moving it to
runtime validation

Please notice that I remove the check at FilterCriteria UnmarshalJSON
because the runtime config can not pass into this validation.

Please help review this change!

core/stateless: add vmwitnessstats cli flag to report leaf stats + log to console (#32619)
The format that is currently reported by the chain isn't very useful, as
it gives an average for ALL the nodes, and not only the leaves, which
skews the results.

Also, until now there was no way to activate the reporting of errors.

We also decided that metrics weren't the right tool to report this data,
so we decided to dump it to the console if the flag is enabled. A better
system should be built, but for now, printing to the logs does the job.

cmd/geth, cmd/utils: log prefunded account/key in ephemeral development mode (#31898)
Some checks are pending
/ Linux Build (push) Waiting to run
/ Linux Build (arm) (push) Waiting to run
/ Docker Image (push) Waiting to run
This PR modifies the disclaimer/banner that is printed when starting up
Geth in dev mode:
* if the client is spun up in ephemeral dev mode with a keystore
override, the address of the first (prefunded) account is printed.
* if the client is spun up in ephemeral mode without a keystore
override, the genesis allocation contains a single static prefunded EOA
account. It's address and private key are logged.
* the banner is printed at the end of client initialization to make it
more prominent. Previously, it was logged towards the beginning of
client initialization and subsequent logging from startup filled the
terminal, pushing it out of view of the user.

Other change is that we now use a static prefunded dev account instead
of generating a random one when instantiating a new dev mode chain.

This is an example of what the banner looks like:

cmd/geth, internal/era/eradl: add era1 downloader tool (#31823)
This adds a geth subcommand for downloading era1 files and placing them into
the correct location. The tool can be used even while geth is already running
on the datadir. Downloads are checked against a hard-coded list of checksums
for mainnet and sepolia.

```
./geth download-era --server $SERVER --block 333333
./geth download-era --server $SERVER --block 333333-444444
./geth download-era --server $SERVER --epoch 0-10
./geth download-era --server $SERVER --all
```

The implementation reuses the file downloader we already had for
fetching build tools. I've done some refactoring on it to make sure it
can support the new use case, and there are some changes to the build
here as well.

beacon/blsync: add checkpoint import/export file feature (#31469)
This PR adds a new `--beacon.checkpoint.file` config flag to geth and
blsync which specifies a checkpoint import/export file. If a file with
an existing checkpoint is specified, it is used for initialization
instead of the hardcoded one (except when `--beacon.checkpoint` is also
specified simultaneously). Whenever the client encounters a new valid
finality update with a suitable finalized beacon block root at an epoch
boundary, it saves the block root in hex format to the checkpoint file.

eth/filters: implement log filter using new log index (#31080)
This PR is #2 of a 3-part series that implements the new log index
intended to replace core/bloombits.
Based on https://github.com/ethereum/go-ethereum/pull/31079
Replaces https://github.com/ethereum/go-ethereum/pull/30370

This part replaces the old bloombits based log search logic in
`eth/filters` to use the new `core/filtermaps` logic.

FilterMaps data structure explanation:
https://gist.github.com/zsfelfoldi/a60795f9da7ae6422f28c7a34e02a07e

Log index generator code overview:

Search pattern matcher code overview:
https://gist.github.com/zsfelfoldi/5981735641c956afb18065e84f8aff34

Note that the possibility of a tree hashing scheme and remote proof
protocol are mentioned in the documents above but they are not exactly
specified yet. These specs are WIP and will be finalized after the local
log indexer/filter code is finalized and merged.

eth/ethconfig: add HistoryMode (#31365)
Here I am adding a config option and geth flag (`--history.chain`) for
configuring history pruning. There are two options available:

- `--history.chain all` is the default and will keep all history like
before.
- `--history.chain postmerge` will configure the history cutoff point to
the merge block.

The option doesn't actually do anything right now, but we need it as a
precursor for other history pruning changes.

metrics, cmd/geth: change init-process of metrics (#30814)
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.

all: remove personal RPC namespace (#30704)
This PR is a first step towards removing account management from geth,
and contains a lot of the user-facing changes.

With this PR, the `personal` namespace disappears. **Note**: `personal`
namespace has been deprecated for quite some time (since
https://github.com/ethereum/go-ethereum/pull/26390 1 year and 8 months
ago), and users who have wanted to use it has been forced to used the
flag `--rpc.enabledeprecatedpersonal`. So I think it's fairly
non-controversial to drop it at this point.

Specifically, this means: 

- Account/wallet listing
  -`personal.getListAccounts`  
  -`personal.listAccounts`     
  -`personal.getListWallets`   
  -`personal.listWallets`      
- Lock/unlock
  -`personal.lockAccount`      
  -`personal.openWallet`       
  -`personal.unlockAccount`
- Sign ops
  -`personal.sign`             
  -`personal.sendTransaction`  
  -`personal.signTransaction`  
- Imports / inits
  -`personal.deriveAccount`    
  -`personal.importRawKey`     
  -`personal.initializeWallet` 
  -`personal.newAccount`       
  -`personal.unpair` 
- Other: 
  -`personal.ecRecover`        


The underlying keystores and account managent code is still in place,
which means that `geth --dev` still works as expected, so that e.g. the
example below still works:

```
> eth.sendTransaction({data:"0x6060", value: 1, from:eth.accounts[0]})
```	

Also, `ethkey` and `clef` are untouched. 

With the removal of `personal`, as far as I know we have no more API
methods which contain credentials, and if we want to implement
logging-capabilities of RPC ingress payload, it would be possible after
this.

beacon, core, eth, miner: integrate witnesses into production Geth (#30069)
This PR integrates witness-enabled block production, witness-creating
payload execution and stateless cross-validation into the `engine` API.
The purpose of the PR is to enable the following use-cases (for API
details, please see next section):

- Cross validating locally created blocks:
- Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to
trigger witness creation too.
- Call `getPayload` as before to retrieve the new block and also the
above created witness.
- Call `executeStatelessPayload` against another client to
cross-validate the block.

- Cross validating locally processed blocks:
- Call `newPayloadWithWitness` instead of `newPayload` to trigger
witness creation too.
- Call `executeStatelessPayload` against another client to
cross-validate the block.

- Block production for stateless clients (local or MEV builders):
- Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to
trigger witness creation too.
- Call `getPayload` as before to retrieve the new block and also the
above created witness.
- Propagate witnesses across the consensus libp2p network for stateless
Ethereum.

- Stateless validator validation:
- Call `executeStatelessPayload` with the propagated witness to
statelessly validate the block.

*Note, the various `WithWitness` methods could also *just be* an
additional boolean flag on the base methods, but this PR wanted to keep
the methods separate until a final consensus is reached on how to
integrate in production.*

---

The following `engine` API types are introduced:

```go
// StatelessPayloadStatusV1 is the result of a stateless payload execution.
type StatelessPayloadStatusV1 struct {
	Status          string      `json:"status"`
	StateRoot       common.Hash `json:"stateRoot"`
	ReceiptsRoot    common.Hash `json:"receiptsRoot"`
	ValidationError *string     `json:"validationError"`
}
```

- Add `forkchoiceUpdatedWithWitnessV1,2,3` with same params and returns
as `forkchoiceUpdatedV1,2,3`, but triggering a stateless witness
building if block production is requested.
- Extend `getPayloadV2,3` to return `executionPayloadEnvelope` with an
additional `witness` field of type `bytes` iff created via
`forkchoiceUpdatedWithWitnessV2,3`.
- Add `newPayloadWithWitnessV1,2,3,4` with same params and returns as
`newPayloadV1,2,3,4`, but triggering a stateless witness creation during
payload execution to allow cross validating it.
- Extend `payloadStatusV1` with a `witness` field of type `bytes` if
returned by `newPayloadWithWitnessV1,2,3,4`.
- Add `executeStatelessPayloadV1,2,3,4` with same base params as
`newPayloadV1,2,3,4` and one more additional param (`witness`) of type
`bytes`. The method returns `statelessPayloadStatusV1`, which mirrors
`payloadStatusV1` but replaces `latestValidHash` with `stateRoot` and
`receiptRoot`.

eth/tracers: live chain tracing with hooks (#29189)
Here we add a Go API for running tracing plugins within the main block import process. 

As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.

The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of 
requiring an interface, for several reasons:

- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
  on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
   to implement only the hooks you want to actually use.

All existing tracers in eth/tracers/native have been rewritten to use the new hook system.

This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

cmd/blsync, beacon/light: beacon chain light client (#28822)
Here we add a beacon chain light client for use by geth.

Geth can now be configured to run against a beacon chain API endpoint,
without pointing a CL to it. To set this up, use the `--beacon.api` flag. Information
provided by the beacon chain is verified, i.e. geth does not blindly trust the beacon
API endpoint in this mode. The root of trust are the beacon chain 'sync committees'.

The configured beacon API endpoint must provide light client data. At this time, only
Lodestar and Nimbus provide the necessary APIs.

There is also a standalone tool, cmd/blsync, which uses the beacon chain light client
to drive any EL implementation via its engine API.

all: replace log15 with slog (#28187)
This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21.

Main changes are as follows:
* removes any log handlers that were unused in the Geth codebase.
* Json, logfmt, and terminal formatters are now slog handlers.
* Verbosity level constants are changed to match slog constant values.  Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options.
* `--log.backtraceat` and `--log.debug` are removed.

The external-facing API is largely the same as the existing Geth logger.  Logger method signatures remain unchanged.

A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically.  This just means that a new logger must be instantiated every time the handler of the root logger is changed.

----
For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did 
```golang
log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true))))
```
You now instead need to do 
```golang
log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true)))
```

cmd, les, tests: remove light client code (#28586)
* cmd, les, tests: remove light client code

This commit removes the light client (LES) code.
Since the merge the light client has been broken and
it is hard to maintain it alongside the normal client.
We decided it would be best to remove it for now and
maybe rework and reintroduce it in the future.

* cmd, eth: remove some more mentions of light mode

* cmd: re-add flags and mark as deprecated

* cmd: warn the user about deprecated flags

* eth: better error message

cmd/{geth,utils}: add cmd to export preimages in snap enumeration order (#28256)
Adds a subcommand: `geth snapshot export-preimages`, to export preimages of every hash found during a snapshot enumeration: that is, it exports _only the active state_, and not _all_ preimages that have been used but are no longer part of the state. 

This tool is needed for the verkle transition, in order to distribute the preimages needed for the conversion. Since only the 'active' preimages are exported, the output is shrunk from ~70GB to ~4GB.

The order of the output is the order used by the snapshot enumeration, which avoids database thrashing. However, it also means that storage-slot preimages are not deduplicated.

cmd/geth: test for logging-output (#28373)
This PR is a bit in preparation for the slog work in #28187 .

Our current test re logging mostly test the internals, but we have no real end-to-end test of the logging output. This PR introduces a simple reexec-based log tester. This also relies upon a special mode in geth, which can be made to eject a set of predefined log messages (only available if the build-tag `integrationtests` is used

e.g. go run --tags=integrationtests ./cmd/geth --log.format terminal logtest

While working on this, I also noticed a quirk in the setup: when geth was configured to use a file output, then two separate handlers were used (one handler for the file, one handler for the console). Using two separate handlers means that two formatters are used, thus the formatting of any/all records happened twice. This PR changes the mechanism to use two separate io.Writers instead, which is both more optimal and fixes a bug which occurs due to a global statefulness in the formatter.

duplicated packages les/catalyst, les/downloader and les/fetcher. These package copies
were created because people wanted to make changes in their eth/ counterparts, but weren't
able to adapt LES code to the API changes.

cmd/geth: use automaxprocs to apply cpu quota correctly (#27506)
It is usually best to set GOMAXPROCS to the number of available CPU cores. However, setting
it like that does not work well when the process is quota-limited to a certain number of CPUs.
The automaxprocs library configures GOMAXPROCS, taking such limits into account.
