Issue statement: when user requests eth_simulateV1 to return full
transaction objects, these objects always had an empty `from` field. The
reason is we lose the sender when translation the message into a
types.Transaction which is then later on serialized.
I did think of an alternative but opted to keep with this approach as it
keeps complexity at the edge. The alternative would be to pass down a
signer object to RPCMarshal* methods and define a custom signer which
keeps the senders in its state and doesn't attempt the signature
recovery.
Fixes https://github.com/ethereum/go-ethereum/issues/31732.
This logic was removed in the recent refactoring in the txindexer to
handle history cutoff (#31393). It was first introduced in this PR:
https://github.com/ethereum/go-ethereum/pull/28908.
I have tested it and it works as an alternative to #31745.
This PR packs 3 changes to the flow of fetching txs from the API:
- It caches the indexer tail after each run is over to avoid hitting the
db all the time as was done originally in #28908.
- Changes `backend.GetTransaction`. It doesn't return an error anymore
when tx indexer is in progress. It shifts the responsibility to the
caller to check the progress. The reason is that in most cases we anyway
check the txpool for the tx. If it was indeed a pending tx we can avoid
the indexer progress check.

This PR changes the chain view update mechanism of the log filter.
Previously the head updates were all wired through the indexer, even in
unindexed mode. This was both a bit weird and also unsafe as the
indexer's chain view was updates asynchronously with some delay, making
some log related tests flaky. Also, the reorg safety of the indexed
search was integrated with unindexed search in a weird way, relying on
`syncRange.ValidBlocks` in the unindexed case too, with a special
condition added to only consider the head of the valid range but not the
tail in the unindexed case.
In this PR the current chain view is directly accessible through the
filter backend and unindexed search is also chain view based, making it
inherently safe. The matcher sync mechanism is now only used for indexed
search as originally intended, removing a few ugly special conditions.
The PR is currently based on top of
https://github.com/ethereum/go-ethereum/pull/31642
Together they fix https://github.com/ethereum/go-ethereum/issues/31518
and replace https://github.com/ethereum/go-ethereum/pull/31542

Shout-out to @Gabriel-Trintinalia for discovering this issue. The gist
of it as follows:
When processing a block, we should provide the parent block as well as
the last 256 block hashes. Some of these parents data (specifically the
hash) was incorrect because even though during the processing of the
parent block we have updated the header, that header was not updating
the TransactionsRoot and ReceiptsRoot fields (types.NewBlock makes a new
copy of the header and changes it only on that instance).

eth_simulate was not processing prague system calls for history contract and EL
requests resulting in inaccurate stateRoot and requestsRoot fields in the block.
Here we add some more changes for live tracing API v1.1:
- Hook `OnSystemCallStartV2` was introduced with `VMContext` as parameter.
- Hook `OnBlockHashRead` was introduced.
- `GetCodeHash` was added to the state interface
- The new `WrapWithJournal` construction helps with tracking EVM reverts in the tracer.

This PR changes the signature of `CalcExcessBlobGas` to take in just
the header timestamp instead of the whole object. It also adds a sanity
check for the parent->child block order to `VerifyEIP4844Header`.
A clarification was made to EIP-7691 stating that at the fork boundary
it is required to use the target blob count associated with the head
block, rather than the parent as implemented here.

This PR builds on #29040 and updates it to the new version of the spec.
I filled the EEST tests and they pass.

The total difficulty is the sum of all block difficulties from genesis
to a certain block. This value was used in PoW for deciding which chain
is heavier, and thus which chain to select. Since PoS has a different
fork selection algorithm, all blocks since the merge have a difficulty
of 0, and all total difficulties are the same for the past 2 years.
Whilst the TDs are mostly useless nowadays, there was never really a
reason to mess around removing them since they are so tiny. This
reasoning changes when we go down the path of pruned chain history. In
order to reconstruct any TD, we **must** retrieve all the headers from
chain head to genesis and then iterate all the difficulties to compute
the TD.
In a world where we completely prune past chain segments (bodies,
receipts, headers), it is not possible to reconstruct the TD at all. In
a world where we still keep chain headers and prune only the rest,
reconstructing it possible as long as we process (or download) the chain
forward from genesis, but trying to snap sync the head first and
backfill later hits the same issue, the TD becomes impossible to
calculate until genesis is backfilled.
All in all, the TD is a messy out-of-state, out-of-consensus computed
field that is overall useless nowadays, but code relying on it forces
the client into certain modes of operation and prevents other modes or
other optimizations. This PR completely nukes out the TD from the node.
It doesn't compute it, it doesn't operate on it, it's as if it didn't
even exist.
Caveats:
- Whenever we have APIs that return TD (devp2p handshake, tracer, etc.)
we return a TD of 0.
- For era files, we recompute the TD during export time (fairly quick)
to retain the format content.
- It is not possible to "verify" the merge point (i.e. with TD gone, TTD
is useless). Since we're not verifying PoW any more, just blindly trust
it, not verifying but blindly trusting the many year old merge point
seems just the same trust model.
- Our tests still need to be able to generate pre and post merge blocks,
so they need a new way to split the merge without TTD. The PR introduces
a settable ttdBlock field on the consensus object which is used by tests
as the block where originally the TTD happened. This is not needed for
live nodes, we never want to generate old blocks.
- One merge transition consensus test was disabled. With a
non-operational TD, testing how the client reacts to TTD is useless, it
cannot react.
Questions:
- Should we also drop total terminal difficulty from the genesis json?
It's a number we cannot react on any more, so maybe it would be cleaner
to get rid of even more concepts.

We still need to decide how to handle non-specfic `chainId` in the JSON
encoding of authorizations. With `chainId` being a uint64, the previous
implementation just used value zero. However, it might actually be more
correct to use the value `null` for this case.
As the node hash scheme in verkle and merkle are totally different, the
original default node hasher in pathdb is no longer suitable. Therefore,
this pull request configures different node hasher respectively.
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.
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`
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.

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 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.

This is one further step towards removing account management from
`geth`. This PR deprecates the flag `unlock`, and makes the flag moot:
unlock via geth is no longer possible.
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.

This PR moves the logging/tracing-facilities out of `*state.StateDB`,
in to a wrapping struct which implements `vm.StateDB` instead.
In most places, it is a pretty straight-forward change:
- First, hoisting the invocations from state objects up to the statedb.
- Then making the mutation-methods simply return the previous value, so
that the external logging layer could log everything.
Some internal code uses the direct object-accessors to mutate the state,
particularly in testing and in setting up state overrides, which means
that these changes are unobservable for the hooked layer. Thus, configuring
the overrides are not necessarily part of the API we want to publish.
The trickiest part about the layering is that when the selfdestructs are
finally deleted during `Finalise`, there's the possibility that someone
sent some ether to it, which is burnt at that point, and thus needs to
be logged. The hooked layer reaches into the inner layer to figure out
these events.
In package `vm`, the conversion from `state.StateDB + hooks` into a
hooked `vm.StateDB` is performed where needed.

Way back we've added `common.math.BigMin` and `common.math.BigMax`.
These were kind of cute helpers, but unfortunate ones, because package
all over out codebase added dependencies to this package just to avoid
having to write out 3 lines of code.
Because of this, we've also started having package name clashes with the
stdlib `math`, which got solves even more badly by moving some helpers
over ***from*** the stdlib into our custom lib (e.g. MaxUint64). The
latter ones were nuked out in a previous PR and this PR nukes out BigMin
and BigMax, inlining them at all call sites.
As we're transitioning to uint256, if need be, we can add a min and max
to that.
calculating a reasonable tx blob fee cap (`max_blob_fee_per_gas *
total_blob_gas`) only depends on the excess blob gas of the parent
header. The parent header is assumed to be correct, so the method should
not be able to fail and return an error.
This is a redo of #29052 based on newer specs. Here we implement EIPs
scheduled for the Prague fork:
- EIP-7002: Execution layer triggerable withdrawals

In #27720, we introduced RPC global gas cap. A value of `0` means an unlimited gas cap. However, this was not the case for simulated calls. This PR fixes the behaviour.
