Since go 1.18 reflect has `reflect.Pointer` which replaces
`reflect.Ptr`. Newer versions of `govet` will alert.

Adds `testing_commitBlockV1`. It is the write companion of `testing_buildBlockV1`:
it builds a block from the provided payload attributes and transactions on
top of the current canonical head, inserts it, and sets it as the new
head, returning the new head hash.

This PR fixes an issue where flat states are continuously persisted
during downloadState, while the sync journal is only persisted at the
end of Sync.
As a result, an unclean shutdown can leave the on-disk flat state ahead
of the journal markers. Some persisted entries may be stale (storage
slots that should have been deleted), and these dangling entries are not
detected or fixed by subsequent state downloads.
To address this, this PR introduces a cleanup step before state
downloading begins. It removes all state entries that are not covered by
the persisted journal markers.
This PR introduces a new condition that if the local node falls behind
too much and the required BAL for catching up is very likely to be
unavailable, the entire snap sync will be restarting from scratch.
As the defined BAL retention window is weak-subjective-period which is
calculated dynamically. A more conservative threshold is used (90K
blocks) for robustness.
Apart from that, the BAL catchup will be divided into several spans and
apply one by one. It's essential to prevent the potential out-of-memory
panic of placing the entire BAL set in memory.
This PR improves the slot reservation logic in the context of snap/2.
Geth has the mechanism to reserve roughly half the peer slots for peers
supporting the snap protocol if snap syncing is needed by local node.
With the context of snap/2, this mechanism should be changed that:
we reserve the slot for the "usable snap peer", not blindly for peer
with snap extension enabled (such as legacy snap/1, which can't serve
the snap/2).
sendInvalidTxs's *eth.TransactionsPacket case iterated `txs` — the
locally-sent invalid transactions, every one of which is in `invalids`
by construction — instead of the transactions actually carried by the
received packet. As a result the loop returned "received bad tx" on the
very first TransactionsPacket the peer sent, regardless of its contents,
and never inspected what was really propagated.
Iterate msg.Items() (the decoded contents of the received packet) so the
"node must not propagate invalid txs" conformance check tests the real
condition instead of producing a false negative.

The stack primitives pop by value: pop() returns the 32-byte value
itself, so every popped operand is copied out of the stack arena before
it is used. The result side was already in place, peek returns a pointer
and binary ops write into the new stack top. This PR fixes the operand
side: pointer-returning primitives (popPtr, popPtrPeek, etc), with the
handlers rewritten to read operands directly from their arena slots.
Every popped operand paid the copy, whatever the op went on to do with
it, so this optimization covers the arithmetic and comparison ops as
much as JUMP, MSTORE, SSTORE and RETURN.
The copy is visible in the assembly. On arm64, master's opLt spends four
instructions moving the popped value through the frame, and the
comparison then reads it back from there:
LDP (R5), (R6, R7) ; load words 0 and 1 of the popped value from the
arena
LDP 16(R5), (R5, R8) ; load words 2 and 3
STP (R6, R7), vm.~r0-64(SP) ; store words 0 and 1 into a frame slot
STP (R5, R8), vm.~r0-48(SP) ; store words 2 and 3
With popPtrPeek those four instructions are gone, the frame shrinks from
locals=0x58 to locals=0x18, and the function from 336 to 288 bytes. The
compiler cannot remove the copy itself: uint256.Int is a four-element
array, and Go's SSA does not promote arrays longer than one element to
registers, so a by-value pop pays this round trip no matter how far
inlining gets, for LT exactly as for ADD.
The CALL and CREATE families are deliberately not converted: a child
frame reuses the same stack arena, so parent pointers into popped slots
die when the child pushes. The rule is recorded on the primitives:
pointers stay valid until the next push or any sub call. Converting the
call family safely means materializing scalars before the child call,
left for later work with a call-heavy benchmark to justify it.
### Benchmarks
Measured with the benchmark suite from #35144 (the evm-bench contract
workloads and the block import benchmark), which is not part of this
PR's diff. Apple M4 Max, fixed iteration counts, n=10, all p=0.000. B/op
and allocs/op are statistically identical on every benchmark:
| benchmark | master | PR | vs master |
|---|---|---|---|
| Snailtracer | 60.0 ms | 54.1 ms | -9.8% |
| TenThousandHashes | 13.2 ms | 12.2 ms | -7.8% |
| ERC20Transfer | 11.7 ms | 11.0 ms | -5.5% |
| ERC20Mint | 7.49 ms | 7.02 ms | -6.2% |
| ERC20ApprovalTransfer | 8.92 ms | 8.44 ms | -5.4% |
This PR is independent of #35144 but plays nicely with it: the generated
dispatch there splices these handler bodies, so the in-place forms land
in its fast path too, where they measure larger.
### Testing
The rewritten handlers run on the interpreter's only execution path, so
correctness rests on references outside the change:
- **Consensus fixtures.** The full tests package passes: state tests,
the execution-spec families, blockchain tests.
- **Opcode testcases.** The JSON testcases compare individual opcode
results against committed expected values.
- **Tracer fixtures.** The tracetest reference files pin exact log and
return data shapes, covering the rewritten LOG and RETURN paths.
- **Cross-build differential.** A goevmlab campaign running this
branch's evm against master's evm over generated state tests across four
forks (Prague, Cancun, London, Osaka) with full trace comparison:
160,566 tests, zero divergences.

`TestTracingHTTPTimeout` still flakes in CI after #35101, failing at the
POST:
--- FAIL: TestTracingHTTPTimeout (0.26s)
tracing_test.go:633: request: Post "http://127.0.0.1:43497": EOF
The test sets a short server `WriteTimeout` and posts a blocking call.
`ContextRequestTimeout` leaves a fixed 100ms for the server to write its
timeout response before the HTTP write deadline cuts the connection.
I can't repro it locally, but my theory is that under load that write
can miss the window, so the connection is dropped and the client POST
returns `EOF`, failing the test before it inspects the span. This is the
only test exposed to it because it is the only one that configures a
`WriteTimeout`.
The EOF is benign: the server sets the timeout error on the SERVER span
before attempting the write, independent of whether the client receives
the response. Since that span status is all the test asserts,
`tryPostJSONRPC` tolerates the transport error instead of failing on it.
This PR fixes an issue that when peers legitimately lack a requested
BAL, empty (0x80) is delivered and this BAL entry will be refetched
over and over again.
A `refused` tracker is added and catchUp will fail if this BAL is
unavailable against the entire peerset.

mainly done in order to judge the complexity of the EIP
and to act as a jumping off point, since the eip will likely
change.

Currently geth ignores the docker `--memory` directive and doesn't
adjust its cache size downward when necessary, potentially running into
OOM.
while gopsutil has functions like `docker/CgroupMem()` they are rather
for reading cgroup memory limit of a container from the host.
This PR adds an optimization to the `findNodeByID` function in
`p2p/discover`. There is already an open PR (#33205) for similar
improvements, and I have further optimized the function to get better
performance. I have attached the benchmark results comparing the current
`main` branch with my `optimized version`, and the results show clear
improvements.

This PR introduces a cache for GetBlobs request.
The main purpose of this PR is to reduce the getBlobs latency by reading and
decoding blobs from the pool in advance of the actual query. This is important
especially in the context of a sparse blobpool, since it may be necessary to
recover blobs from cells on a getBlobs request.
Previously, the Engine API read and decoded blobs from the pool on every call.
Now those calls check the cache and only fall back to the pool on a miss.
The cache has two modes:
- In topK mode (default), it wakes up periodically, picks the most profitable
pending blob transactions up to the current fork's maxBlobsPerBlock, and loads
their blobs. The selection logic is shared with the miner's block-building
logic. The selection size is derived from eip4844.MaxBlobsPerBlock at the
current head.
- When the CL calls HasBlobs, the cache switches to hasBlobs mode and tries to
pin the set it just reported as available. Cache updates (read, decode, and
optionally conversion in the future) run in background goroutines.

Adds snap/2 (EIP-8189), a block-access-list (BAL) based state sync, and
wires it to run side by side with snap/1. It's opt-in (for now) behind a
new --snap.v2 flag and chosen at startup.

In old code, mu is struct not pointer, it caused create new mutex event
with same writer. Change to use pointer to sync.Mutex, so that the mutex
is shared between handler with same writer.
This adds a client option to configure trace context propagation via the
`traceparent` HTTP header.
I'm adding this so that prysm can enable distributed tracing on their
engine API client.
This is a PR that removes all correctly flagged typos, in order to stop
an onslaught of slop PRs in its tracks. It should be followed by #34994
but the latter needs more configuration work and I want to limit the
stem of PRs right now.
Fixes an issue where we would falsely return 400 when we should return
200 because the request was served successfully
