This PR adds server-side limits for JSON-RPC batch requests. Before this change, batches
were limited only by processing time. The server would pick calls from the batch and
answer them until the response timeout occurred, then stop processing the remaining batch
items.
Here, we are adding two additional limits which can be configured:
- the 'item limit': batches can have at most N items
- the 'response size limit': batches can contain at most X response bytes
These limits are optional in package rpc. In Geth, we set a default limit of 1000 items
and 25MB response size.
When a batch goes over the limit, an error response is returned to the client. However,
doing this correctly isn't always possible. In JSON-RPC, only method calls with a valid
`id` can be responded to. Since batches may also contain non-call messages or
notifications, the best effort thing we can do to report an error with the batch itself is
reporting the limit violation as an error for the first method call in the batch. If a batch is
too large, but contains only notifications and responses, the error will be reported with
a null `id`.
The RPC client was also changed so it can deal with errors resulting from too large
batches. An older client connected to the server code in this PR could get stuck
until the request timeout occurred when the batch is too large. **Upgrading to a version
of the RPC client containing this change is strongly recommended to avoid timeout issues.**
For some weird reason, when writing the original client implementation, @fjl worked off of
the assumption that responses could be distributed across batches arbitrarily. So for a
batch request containing requests `[A B C]`, the server could respond with `[A B C]` but
also with `[A B] [C]` or even `[A] [B] [C]` and it wouldn't make a difference to the
client.
So in the implementation of BatchCallContext, the client waited for all requests in the
batch individually. If the server didn't respond to some of the requests in the batch, the
client would eventually just time out (if a context was used).
With the addition of batch limits into the server, we anticipate that people will hit this
kind of error way more often. To handle this properly, the client now waits for a single
response batch and expects it to contain all responses to the requests.

When block import fails, the error displays the number of the first block past the import batch, not the number of the failing block. This change fixes this problem by identifying which blocks fails and reporting its number.
rename parameter
In this case, the naming of "extapi" might create some confusion. Although it represents an External Signer Backend, its name could be mistaken for an API. In reality, it is a backend instance used for communicating with external signers. A better naming choice could be "extBackend" or "externalBackend" to more accurately describe that it is a backend instance rather than an API.
Makes the `geth account ... ` commands usable even if a geth-process is already executing, since the account commands do not read the chaindata, it was not required for those to use the same locking mechanism.

Follow-up to #26697, makes the crawler less verbose on route53-based scenarios.
It also changes the loglevel from debug to info on Updates, which are typically the root, and can be interesting to see.
This PR removes the Debug field from vmconfig, making it so that if a tracer is set, debug=true is implied.

Currently the t8n tool uses the same block number for the current block and its parent while calculating the base fee. This causes incorrect base fee calculation for the london fork block. This commit sets the parent block number to be one less than the current block number
With #25287 we made it so that preimages were not recorded by default. This had the side effect that the evm command is no longer able to dump state since it does a preimage lookup to determine the address represented by a key.
This change enables the recording of preimages when the dump command is given.
Here, the core.Message interface turns into a plain struct and
types.Message gets removed.
This is a breaking change to packages core and core/types. While we do
not promise API stability for package core, we do for core/types. An
exception can be made for types.Message, since it doesn't have any
purpose apart from invoking the state transition in package core.
types.Message was also marked deprecated by the same commit it
got added in, 4dca5d4db7 (November 2016).
The core.Message interface was added in December 2014, in commit
db494170dc, for the purpose of 'testing' state transitions. It's the
same change that made transaction struct fields private. Before that,
the state transition used *types.Transaction directly.
Over time, multiple implementations of the interface accrued across
different packages, since constructing a Message is required whenever
one wants to invoke the state transition. These implementations all
looked very similar, a struct with private fields exposing the fields
as accessor methods.
By changing Message into a struct with public fields we can remove all
these useless interface implementations. It will also hopefully
simplify future changes to the type with less updates to apply across
all of go-ethereum when a field is added to Message.

The EmptyRootHash and EmptyCodeHash are defined everywhere in the codebase, this PR replaces all of them with unified one defined in core/types package, and also defines constants for TxRoot, WithdrawalsRoot and UncleRoot
Our discovery crawler spits out a huge amount of logs, most of which is pretty non-interesting. This change moves the very verbose output to Debug, and adds a 8-second status log message giving the general idea about what's going on.
This change ports some changes from the main PBSS PR:
- get rid of callback function in `trie.Database.Commit` which is not required anymore
- rework the `nodeResolver` in `trie.Iterator` to make it compatible with multiple state scheme
- some other shallow changes in tests and typo-fixes
This PR moves some trie-related db accessor methods to a different file, and also removes the schema type. Instead of the schema type, a string is used to distinguish between hashbased/pathbased db accessors.
This also moves some code from trie package to rawdb package.
This PR is intended to be a no-functionality-change prep PR for #25963 .

This fixes a regression where the flag did not accept values without
the 0x prefix anymore. What's worse, if an invalid value was passed,
the client would just log an INFO level message and continue.
This change introduces a breaking change to miner.etherbase is configured.
Previously, users did not need to explicitly set the etherbase address via flag, since 'first' local account was used as etherbase automatically. This change removes the "default first account" feature.
In Proof-of-stake world, the fee recipient address is provided by CL, and not configured in Geth any more - meaning that miner.etherbase is mostly for legacy networks(pow, clique networks etc).
This PR does a few things.
It fixes a shutdown-order flaw in the chainfreezer. Previously, the chain-freezer would shutdown the freezer backend first, and then signal for the loop to exit. This can lead to a scenario where the freezer tries to fsync closed files, which is an error-conditon that could lead to exit via log.Crit.
It also makes the printout more detailed when truncating 'dangling' items, by showing the exact number instead of approximate MB.
This PR also adds calls to fsync files before closing them, and also makes the `db inspect` command slightly more robust.

* p2p/discover: add more packet information in logs
This adds more fields to discv5 packet logs. These can be useful when
debugging multi-packet interactions.
The FINDNODE message also gets an additional field, OpID for debugging
purposes. This field is not encoded onto the wire.
I'm also removing topic system related message types in this change.
These will come back in the future, where support for them will be
guarded by a config flag.
* p2p/discover/v5wire: rename 'Total' to 'RespCount'
The new name captures the meaning of this field better.
This PR builds on #26299, but also updates the tests to the most recent version, which includes tests regarding TheMerge.
This change adds checks to the beacon consensus engine, making it more strict in validating the pre- and post-headers, and not relying on the caller to have already correctly sanitized the headers/blocks.
--syncTarget is a feature for development purpose in post-merge world. Previously
it's added into eth.Config. But it turns out that's a stupid idea.
- syncTarget is a block object, which is hard to be put in config file(large)
- syncTarget is just a dev feature, doesn't make too much sense to add it in config file
So I remove it from the eth config object. And it also fixes the #26328
The new flag allows configuring an explicit endpoint which is to be
announced in the DHT. This feature was originally developed for the
discv5 wormhole experiment (#25798), but it's useful in other contexts
as well.
This PR drops the legacy receipt types, the freezer-migrate command and the startup check. The previous attempt #22852 at this failed because there were users who still had legacy receipts in their db, so it had to be reverted #23247. Since then we added a command to migrate legacy dbs #24028.
As of the last hardforks all users either must have done the migration, or used the --ignore-legacy-receipts flag which will stop working now.
This PR introduces a node scheme abstraction. The interface is only implemented by `hashScheme` at the moment, but will be extended by `pathScheme` very soon.
Apart from that, a few changes are also included which is worth mentioning:
- port the changes in the stacktrie, tracking the path prefix of nodes during commit
- use ethdb.Database for constructing trie.Database. This is not necessary right now, but it is required for path-based used to open reverse diff freezer
This commit adds support for two new commands to clef, making it possible to list accounts / wallets from the command-line-interface.

This PR adds a parameter to startup, --synctarget. The synctarget flag is a developer-flag, that can be useful in some scenarios as a replacement for a CL node. It defines a fixed block sync target:
geth --syncmode=full --synctarget=./block_15816882.hex_rlp
The --synctarget is only made available during syncmode=full
Currently, in order to chain together sequential valid t8n transitions the caller must manually calculate the block base fee. This PR adds support for the necessary parent fee market data to calculate the base fee for the current transition.
Concretely, env is extended to accept the following:
parentBaseFee
parentGasUsed
parentGasLimit
Example usage can be found in ./cmd/evm/testdata/25.
