This PR makes a small update to the `Pending()` method in the legacy
pool. By changing the lock from exclusive to read-only, it aims to
improve concurrency performance.

This is an alternative PR for
https://github.com/ethereum/go-ethereum/pull/34746.
This PR implements the second approach among the two possible solutions
mentioned in the above PR.
Requests for unavailable items are possible when the peer is following a
different fork from us. However this is not expected to happen
frequently. Considering the amount of complexity added to the codebase,
the simpler approach (this PR) can be preferred.
This PR adds `AdoptSyncedState()` alongside `Enable()`. It does the same
pathdb bookkeeping (now factored into a shared `resetForReactivation()`
helper), but skips the regeneration. The wiring/calling code lands in
#34626

When `io.Copy` succeeds but the buffered `Close` fails (e.g. disk full
on `Flush`), the error was swallowed and verification reported a
misleading hash mismatch instead of the real I/O failure. Keep the
`Close` error when `io.Copy` didn't already produce one.

## Summary
Fixes#31917.
`geth era-download` now only prints `is stale` when an existing
downloaded file fails checksum verification. Missing files are still
downloaded normally, but no longer get mislabeled as stale.
## Why
`DownloadFile` used `verifyHash` for both missing files and checksum
mismatches, then printed `is stale` for any error. This made first-time
downloads look like corrupt or outdated files.
## Validation
- `make all`
- `go run ./build/ci.go test`
- `go run ./build/ci.go lint`
- `go run ./build/ci.go check_generate`
- `go run ./build/ci.go check_baddeps`

The refactor from `for el := plist.Front(); ...; el = el.Next()` to the
new `iterList` iterator in #34743 silently dropped two things needed by
resetTimeout:
1. `nextTimeout = el.Value.(*replyMatcher)` at the top of the loop. This
assignment is what gives `nextTimeout` its documented meaning ("head of
plist when timeout was last reset"), and what makes the early-return
optimization at the top of resetTimeout work. Without it, nextTimeout is
only ever written to nil, so `nextTimeout == plist.Front().Value` is
always false and the optimization is dead.
2. `nextTimeout.errc <- errClockWarp` in the clock-warp branch now reads
a stale or nil pointer. Prior to the refactor, the inner assignment kept
nextTimeout pointing at the current matcher so its errc was the right
channel to receive the errClockWarp signal. After the refactor, on first
entry into the clock-warp branch nextTimeout is nil, which panics the
UDPv4 loop goroutine with a nil pointer deref and takes discv4 down.
Re-assign `nextTimeout = p` at the head of the loop (restoring the
documented invariant) and send the clock-warp error on `p.errc` rather
than the now-stale `nextTimeout.errc`.
The clock-warp branch triggers only when the system clock jumps backward
after a deadline is assigned (deadline - time.Now() >= 2*respTimeout,
i.e. at least ~500ms backward jump), which is why this regression
slipped past CI - it is not exercised by any existing unit test, and
writing one would require plumbing a clock through the loop.
The reconstruct callback indexes parallel response slices (bodies,
receipts). Passing the accept counter used the wrong element when an
earlier header in the same batch hit a stale slot.
the gapped queue cap was effectively per-sender rather than total — a
sender pool spread across enough distinct addresses could grow
`p.gapped` well past `maxGapped`, defeating the resource bound.
`maxGapped` was being compared against `len(p.gapped)`, which is a
`map[address][]tx` and counts unique senders, not queued txs. Switched
the check to `len(p.gappedSource)` (keyed by tx hash, so its length is
the real total). Also wired up a `blobpool/gapped/count` gauge plus
`promoted`, `evicted`, and `gappedfull` meters so queue size and churn
are actually observable in prod.
Disables the recently added log indexer from a simulated backend.
In most cases the log indexer is not required and unindexed search
should be fast enough.
Fixes https://github.com/ethereum/go-ethereum/issues/32552.
This updates the typed `ethclient` model for `eth_simulateV1` call
results to include `maxUsedGas`, matching the field already returned by
the server-side RPC response.
Follow-up to #32789.
The mux tracer fanned out every standard hook to its children but never
forwarded OnSystemCall{Start,End}. Tracers that rely on these - like
`logger.jsonLogger`, which uses the start hook to silence its opcode
hook for the duration of a system call - never got the signal when
wrapped behind a mux.
In evm t8n, combining `--trace` with `--opcode-count` (default for geth
with exec specs) produces exactly that wrapping. The first system call
(e.g. `ProcessBeaconBlockRoot`) then fires `OnOpcode` on the json logger
before any `OnTxStart` has run, dereferencing a nil env and crashing
t8n.
Forward both hooks through the mux. The V2 fan-out falls back to V1 for
children that only implement the legacy hook, mirroring the precedence
already used in `core/state_processor.go`.
This PR addresses one of the biggest performance issue with binary
tries: storing each internal node individually bloats the index, the
disk, and triggers a lot of write amplifications. To fix this issue,
this PR serializes groups of nodes together.
Because we are still looking for the ideal group size, the "depth" of
the group tree is made a parameter, but that will be removed in the
future, once the perfect size is known.
This is a rebase of #33658

The layer-5 diff condition used `i > 50 || i < 85`, which is true for
almost all keys in the 0..255 loop. Use `i > 50 && i < 85` so layer 5
only covers the intended band (51..84), consistent with the snapshot
iterator test fix.
- Fixes an error shadowing issue in the deliver() function, where a
stale result from GetDeliverySlot caused the original failure to be
overwritten by errStaleDelivery.
- Adds errInvalidBody and errInvalidReceipt to the downloader error
checks to properly drop peers who sent invalid responses.

EIP-7825 caps the transaction gas limit at `MaxTxGas`, but after
Amsterdam/EIP-8037 the transaction gas limit can include state gas
reservoir in addition to the regular gas dimension. Applying the Osaka
cap to the full `tx.Gas()` rejects otherwise valid Amsterdam
transactions that need more than `MaxTxGas` total gas because of state
gas, while their regular gas use remains within the intended limit.
This changes geth to stop applying the full transaction gas cap once
Amsterdam is active:
- txpool stateless validation no longer rejects `tx.Gas() > MaxTxGas`
under Amsterdam
- legacy pool reorg cleanup does not purge high-total-gas transactions
at the Osaka transition if Amsterdam is also active
- execution precheck mirrors the txpool behavior and does not reject
high-total-gas messages under Amsterdam
The block gas limit check remains in place, so transactions still cannot
request more total gas than the current block gas limit.
Validation run:
```
go test ./core/txpool ./core/txpool/legacypool
go test ./core -run TestStateProcessorErrors
```

Here, we change the EVM stack implementation to use an 'arena', i.e.
a shared allocation pool for sub-call stacks. The stack is now more
GC-friendly, since it is a slice of uint256 values instead of a slice of pointers.
Code that pushes an item to the stack has been changed to get() the top
item, then overwrite it.
The PR is a rewrite/rebase of #30362.

Save `el.Next()` before calling `plist.Remove(el)` so iteration

`StateSetWithOrigin.decode()` was missing size computation after
deserializing origin data, causing `size` to remain zero after journal
reload. Added the same calculation logic used in
`NewStateSetWithOrigin()`.
This PR updates the BAL structure definition to the latest the spec,
- Balance has been changed from [16]byte to uint256
- Storage key and value has been changed from [32]byte to uint256
- BlockAccessList has been changed from a struct to a slice of
AccountChanges
- TxIndex has been changed from uint16 to uint32
The stateReadList field introduced by #34776 to track the state access
footprint for EIP-7928 was not propagated by StateDB.Copy. Every other
per-transaction field that lives alongside it (accessList,
transientStorage, journal, witness, accessEvents) is copied explicitly,
so this field was simply missed.
After Copy the copy's stateReadList is nil while the original keeps its
entries, so the nil-safe guards on StateAccessList.AddAccount / AddState
silently drop every access recorded on the copy. For any post-Amsterdam
code path that copies a prepared state and keeps reading from the copy,
the BAL footprint becomes incomplete.
Add a Copy method on bal.StateAccessList and invoke it from
StateDB.Copy, matching the pattern used for accessList and accessEvents.

The testPeer request counters (nAccountRequests, nStorageRequests,
nBytecodeRequests, nTrienodeRequests) were plain int fields incremented
with ++. These increments happen in Request* methods that are invoked
concurrently by the Syncer from multiple goroutines
(assignBytecodeTasks, assignStorageTasks, etc.), causing a data race
reliably detected by go test -race.
Change the counters to atomic.Int64 so increments and reads are
synchronized without introducing a mutex.
Fixes races detected in TestMultiSyncManyUseless,
TestMultiSyncManyUselessWithLowTimeout,
TestMultiSyncManyUnresponsive, TestSyncWithStorageAndOneCappedPeer,
TestSyncWithStorageAndCorruptPeer, and
TestSyncWithStorageAndNonProvingPeer.
scheduleFetches.func1 is the biggest allocator in the long-duration
profile of node (11% of total alloc_space).
Each peer-iteration pre-allocated make([]common.Hash, 0, maxTxRetrievals),
even for peers that end up collecting no new hashes (all their announces
were already being fetched by someone else).
Defer the slice allocation to the first append. Peers that collect zero hashes
now pay zero allocation, which is the common case on the timeoutTrigger
path where all peers with any announces are iterated.
When `rpc.Client.Close()` is called, the TCP connection is torn down
without sending a WebSocket Close frame. The server sees `websocket:
close 1006 (abnormal closure): unexpected EOF` instead of a clean 1000
(normal closure).
### Root cause
`websocketCodec.close()` delegates to `jsonCodec.close()` which calls
`c.conn.Close()` — gorilla/websocket's `Conn.Close` explicitly "[closes
the underlying network connection without sending or waiting for a close
message](https://pkg.go.dev/github.com/gorilla/websocket#Conn.Close)"
(per RFC 6455).
### Fix
Send a WebSocket Close control frame (opcode 0x8, status 1000) before
closing the underlying connection. Uses `WriteControl` with the same
`encMu` mutex pattern already used by `pingLoop` for write
serialization, and reuses the existing `wsPingWriteTimeout` (5s)
constant.
`WriteControl` errors are safe to ignore — the connection may already be
broken by the time we attempt the close frame.
Fixes#30482
This PR adds three cell-level kzg functions required for the sparse
blobpool (eth/72).
- VerifyCells: Verifies cells corresponding to proofs. This is used to
verify cells received from eth/72 peers.
- ComputeCells: Computes cells from blobs. This is needed because user
submissions and eth/71 transaction deliveries contain blobs, while
eth/72 peers expect cells.
- RecoverBlobs: Recovers blobs from partial cells. This is needed to
support both eth/71 and eth/72

The rlpx ping command mishandled disconnect responses on two counts:
the error return from rlp.DecodeBytes was ignored, so decode failures
silently produced an "invalid disconnect message" error with no context;
and the decoder assumed the spec-compliant list form exclusively, while
older geth and some other implementations send the reason as a bare
byte.
Accept both wire forms (matching the legacy-tolerant behavior already
in p2p.decodeDisconnectMessage), and on decode failure include the raw
payload so operators can see exactly what the peer sent. Add a unit
test for the decoder covering both forms plus the empty-payload error
path.
This PR reverts the last change to the freebsd build, and it fixes the
_direct_ FreeBSD build.
Here, we change the upstream of github.com/karalabe/hid to its new home,
github.com/ethereum/hid. The new dependency includes a dummy.go file
that makes `go mod vendor` work.
##### Origin of the problem
Enrique is maintaining the FreeBSD ports, and FreeBSD ports only support
vendored go modules. It turns out that `go mod vendor` will not include
C files if there is no `.go` file in the directory. Since the C files
were missing for `karalabe/hid`, the ports maintainer tried to use the
version of `hidapi` that is provided by the ports. To do so, he had to
modify the way things are included. This broke the _out of ports_
FreeBSD build.
Difference to Appveyor:
- Missing 386 build. Hit some issue because user-space memory there is
around 2Gbs. Also seems generally extremely niche.
- Not doing the archive step and NSIS installer and uploads (those are
done on the builder).
This PR removes `FinalizeAndAssemble` from the consensus engine
interface
and relocates block assembly logic outside of the consensus engine.
Block assembly is consensus-agnostic. Most validations can be performed
by the caller. For example:
- Withdrawals must be nil prior to Shanghai
- After Shanghai upgrade, withdrawals must be non-nil, even if empty.
The only notable consensus-specific validation is related to uncles. In
clique,
the concept of uncles does not exist, and any block containing uncles
should
be considered invalid.
Within the block production package, the policy is to produce blocks
according
to the latest chain specification. As a result, Clique-specific block
production
is no longer supported. This tradeoff is considered acceptable.
