This introduces an error when the filter has both `blockHash` and
`fromBlock`/`toBlock`, since these are mutually exclusive. Seems the
tests were actually returning `not found` error, which went undetected
since there was no check on the actual returned error in the test.
This adds a method on vm.EVM to set the jumpdest cache implementation.
It can be used to maintain an analysis cache across VM invocations, to improve
performance by skipping the analysis for already known contracts.

This pull request optimizes trie hashing by reducing memory allocation
overhead. Specifically:
- define a fullNodeEncoder pool to reuse encoders and avoid memory
allocations.
- simplify the encoding logic for shortNode and fullNode by getting rid
of the Go interfaces.
This PR addresses a flakiness in the rollback test discussed in
https://github.com/ethereum/go-ethereum/issues/32252
I found `nonce` collision caused transactions occasionally fail to send.
I tried to change error message in the failed test like:
```
if err = client.SendTransaction(ctx, signedTx); err != nil {
t.Fatalf("failed to send transaction: %v, nonce: %d", err, signedTx.Nonce())
}
```
and I occasionally got test failure with this message:
```
=== CONT TestFlakyFunction/Run_#100
rollback_test.go:44: failed to send transaction: already known, nonce: 0
--- FAIL: TestFlakyFunction/Run_#100 (0.07s)
```
Although `nonces` are obtained via `PendingNonceAt`, we observed that,
in rare cases (approximately 1 in 1000), two transactions from the same
sender end up with the same nonce. This likely happens because `tx0` has
not yet propagated to the transaction pool before `tx1` requests its
nonce. When the test succeeds, `tx0` and `tx1` have nonces `0` and `1`,
respectively. However, in rare failures, both transactions end up with
nonce `0`.
We modified the test to explicitly assign nonces to each transaction. By
controlling the nonce values manually, we eliminated the race condition
and ensured consistent behavior. After several thousand runs, the
flakiness was no longer reproducible in my local environment.
Reduced internal polling interval in `pendingStateHasTx()` to speed up
test execution without impacting stability. It reduces test time for
`TestTransactionRollbackBehavior` from about 7 seconds to 2 seconds.
Correct the error message in the ExecuteStatelessPayloadV4 function to
reference newPayloadV4 and the Prague fork, instead of incorrectly
referencing newPayloadV3 and Cancun.
This improves clarity during debugging and aligns the error message with
the actual function and fork being validated. No logic is changed.

Replace manual byte-by-byte XOR implementation with the optimized
bitutil.XORBytes function. This improves performance by using word-sized
operations on supported architectures while maintaining the same
functionality. The optimized version processes data in bulk rather than
one byte at a time

`binary.AppendUvarint` offers better performance than using append
directly, because it avoids unnecessary memory allocation and copying.
In our case, it can increase the performance by +35.8% for the
`blockWriter.append` function:
```
benchmark old ns/op new ns/op delta
BenchmarkBlockWriterAppend-8 5.97 3.83 -35.80%

[EIP-7594](https://eips.ethereum.org/EIPS/eip-7594) defines a limit of
max 6 blobs per transaction. We need to enforce this limit during block
processing.
> Additionally, a limit of 6 blobs per transaction is introduced.
Clients MUST enforce this limit when validating blob transactions at
submission time, when received from the network, and during block
production and processing.
The main purpose of this change is to enforce the version setting when
constructing the blobSidecar, avoiding creating sidecar with wrong/default
version tag.
The implementation of `parseIndexBlock` used a reverse loop with slice
appends to build the restart points, which was less cache-friendly and
involved unnecessary allocations and operations. In this PR we change
the implementation to read and validate the restart points in one single
forward loop.
Here is the benchmark test:
```bash
go test -benchmem -bench=BenchmarkParseIndexBlock ./triedb/pathdb/
```
The result as below:
```
benchmark old ns/op new ns/op delta
BenchmarkParseIndexBlock-8 52.9 37.5 -29.05%
```
about 29% improvements

Fixes#32175.
This fixes the scenario where the blockhash opcode would return 0x0
during RPC simulations when using BlockOverrides with a future block
number. The root cause was that BlockOverrides.Apply() only modified the
vm.BlockContext, but GetHashFn() depends on the actual
types.Header.Number to resolve valid historical block hashes. This
caused a mismatch and resulted in incorrect behavior during trace and
call simulations.

The root cause of the flaky test was a nonce conflict caused by async
contract deployments.
This solution defines a custom deployer with automatic nonce management.
This is something interesting I came across during my benchmarks, we
spent ~3.8% of all allocations allocating the header number on the heap.

This pull request slightly improves the freezer fsync mechanism by scheduling
the Sync operation based on the number of uncommitted items and original
time interval.
Originally, freezer.Sync was triggered every 30 seconds, which worked well during
active chain synchronization. However, once the initial state sync is complete,
the fixed interval causes Sync to be scheduled too frequently.
To address this, the scheduling logic has been improved to consider both the time
interval and the number of uncommitted items. This additional condition helps
avoid unnecessary Sync operations when the chain is idle.
Introduce file-based state journal in path database, fixing
the Pebble restriction when the journal size exceeds 4GB.

This PR fixes an issue in the tx_fetcher DoS prevention logic where the
code keeps the overflow amount (`want - maxTxAnnounces`) instead of the
allowed amount (`maxTxAnnounces - used`). The specific changes are:
- Correct slice indexing in the announcement drop logic
- Extend the overflow test case to cover the inversion scenario
This is a resubmit of https://github.com/ethereum/go-ethereum/pull/31820
