## Summary
In binary trie mode, `IntermediateRoot` calls `updateTrie()` once per
dirty account. But with the binary trie there is only one unified trie
(`OpenStorageTrie` returns `self`), so each call redundantly does
per-account trie setup: `getPrefetchedTrie`, `getTrie`, slice
allocations for deletions/used, and `prefetcher.used` — all for the same
trie pointer.
This PR replaces the per-account `updateTrie()` calls with a single flat
loop that applies all storage updates directly to `s.trie`. The MPT path
is unchanged. The prefetcher trie replacement is guarded to avoid
overwriting the binary trie that received updates.
This is the phase-1 counterpart to #34021 (H01). H01 fixes the commit
phase (`trie.Commit()` called N+1 times). This PR fixes the update phase
(`updateTrie()` called N times with redundant setup). Same root cause —
unified binary trie operated on per-account — different phases.

EIP-7928 brings state reads into consensus by recording accounts and storage accessed during execution in the block access list. As part of the spec, we need to check that there is enough gas available to cover the cost component which doesn't depend on looking up state. If this component can't be covered by the available gas, we exit immediately.
The portion of the call dynamic cost which doesn't depend on state look ups:
- EIP2929 call costs
- value transfer cost
- memory expansion cost
This PR:
- breaks up the "inner" gas calculation for each call variant into a pair of stateless/stateful cost methods
- modifies the gas calculation logic of calls to check stateless cost component first, and go out of gas immediately if it is not covered.

This PR introduces a new type HistoryPolicy which captures user intent
as opposed to pruning point stored in the blockchain which persists the
actual tail of data in the database.
It is in preparation for the rolling history expiry feature.
It comes with a semantic change: if database was pruned and geth is
running without a history mode flag (or explicit keep all flag) geth
will emit a warning but continue running as opposed to stopping the
world.
## Summary
At tree depths below `log2(NumCPU)` (clamped to [2, 8]), hash the left
subtree in a goroutine while hashing the right subtree inline. This
exploits available CPU cores for the top levels of the tree where
subtree hashing is most expensive. On single-core machines, the parallel
path is disabled entirely.
Deeper nodes use sequential hashing with the existing `sync.Pool` hasher
where goroutine overhead would exceed the hash computation cost. The
parallel path uses `sha256.Sum256` with a stack-allocated buffer to
avoid pool contention across goroutines.
**Safety:**
- Left/right subtrees are disjoint — no shared mutable state
- `sync.WaitGroup` provides happens-before guarantee for the result
- `defer wg.Done()` + `recover()` prevents goroutine panics from
crashing the process
- `!bt.mustRecompute` early return means clean nodes never enter the
parallel path
- Hash results are deterministic regardless of computation order — no
consensus risk

Found this bug while implementing the Amsterdam changes t8n changes for
benchmark test filling in EELS.
Prefixes were incorrectly being stripped on requests over t8n and this
was leading to `fill` correctly catching hash mismatches on the EELS
side for some BAL tests. Though this was caught there, I think this
change might as well be cherry-picked there instead and merged to
`master`.
This PR brings this behavior to parity with EELS for Osaka filling.
There are still some quirks with regards to invalid block tests but I
did not investigate this further.
This PR improves the pbss archive mode. Initial sync
of an archive mode which has the --gcmode archive
flag enabled will be significantly sped up.
It achieves that with the following changes:
The indexer now attempts to process histories in batch whenever
possible.
Batch indexing is enforced when the node is still syncing and the local
chain
head is behind the network chain head.
In this scenario, instead of scheduling indexing frequently alongside
block
insertion, the indexer waits until a sufficient amount of history has
accumulated
and then processes it in a batch, which is significantly more efficient.

## Summary
**Bug fix.** In Verkle mode, all state objects share a single unified
trie (`OpenStorageTrie` returns `self`). During `stateDB.commit()`, the
main account trie is committed via `s.trie.Commit(true)`, which calls
`CollectNodes` to traverse and serialize the entire tree. However, each
dirty account's `obj.commit()` also calls `s.trie.Commit(false)` on the
**same trie object**, redundantly traversing and serializing the full
tree once per dirty account.
With N dirty accounts per block, this causes **N+1 full-tree
traversals** instead of 1. On a write-heavy workload (2250 SSTOREs),
this produces ~131 GB of allocations per block from duplicate NodeSet
creation and serialization. It also causes a latent data race from N+1
goroutines concurrently calling `CollectNodes` on shared `InternalNode`
objects.
This commit adds an `IsVerkle()` early return in `stateObject.commit()`
to skip the redundant `trie.Commit()` call.

cgo builds have been broken in FreeBSD ports because of the hid lib.
@enriquefynn has made a temporary patch, but the fix has been merged in
the master branch, so let's reflect that here.
The signify flag in `doWindowsInstaller` was defined as "signify key"
(with a space), making it impossible to pass via CLI (`-signify
<value>`). This meant the Windows installer signify signing was silently
never executed.
Fix by renaming the flag to "signify", consistent with `doArchive` and
`doKeeperArchive`.
The slotNumber field was being passed as a raw *uint64 to the JSON
marshaler, which serializes it as a plain decimal integer (e.g. 159).
All Ethereum JSON-RPC quantity fields must be hex-encoded per spec.
Wrap with hexutil.Uint64 to match the encoding of other numeric header
fields like blobGasUsed and excessBlobGas.

This PR improves `db inspect` classification accuracy in
`core/rawdb/database.go` by tightening key-shape checks for:
- `Block number->hash`
- `Difficulties (deprecated)`
Previously, both categories used prefix/suffix heuristics and could
mis-bucket unrelated entries.
Binary tree hashing is quite slow, owing to many factors. One of them is
the GC pressure that is the consequence of allocating many hashers, as a
binary tree has 4x the size of an MPT. This PR introduces an
optimization that already exists for the MPT: keep a pool of hashers, in
order to reduce the amount of allocations.

`TestSubscribePendingTxHashes` hangs indefinitely because pending tx
events are permanently missed due to a race condition in
`NewPendingTransactions` (and `NewHeads`). Both handlers called their
event subscription functions (`SubscribePendingTxs`,
`SubscribeNewHeads`) inside goroutines, so the RPC handler returned the
subscription ID to the client before the filter was installed in the
event loop. When the client then sent a transaction, the event fired but
no filter existed to catch it — the event was silently lost.
- Move `SubscribePendingTxs` and `SubscribeNewHeads` calls out of
goroutines so filters are installed synchronously before the RPC
response is sent, matching the pattern already used by `Logs` and
`TransactionReceipts`

Fixes https://github.com/ethereum/go-ethereum/issues/33907
Notably there is a behavioral change:
- Previously Geth will refuse to restart if the existing trienode
history is gapped with the state data
- With this PR, the gapped trienode history will be entirely reset and
being constructed from scratch
This PR adds a cmd tool fetchpayload which connects to a
node and gets all the information in order to create a serialized
payload that can then be passed to the zkvm.
This PR allows users to prune their nodes up to the Prague fork. It
indirectly depends on #32157 and can't really be merged before eraE
files are widely available for download.
The `--history.chain` flag becomes mandatory for `prune-history`
command. Here I've listed all the edge cases that can happen and how we
behave:
## prune-history Behavior
| From | To | Result |
|-------------|--------------|--------------------------|
| full | postmerge | ✅ prunes |
| full | postprague | ✅ prunes |
| postmerge | postprague | ✅ prunes further |
| postprague | postmerge | ❌ can't unprune |
| any | all | ❌ use import-history |
## Node Startup Behavior
| DB State | Flag | Result |
|-------------|--------------|----------------------------------------------------------------|
| fresh | postprague | ✅ syncs from Prague |
| full | postprague | ❌ "run prune-history first" |
| postmerge | postprague | ❌ "run prune-history first" |
| postprague | postmerge | ❌ "can't unprune, use import-history or fix
flag" |
| pruned | all | ✅ accepts known prune points |
The `--remove.chain` flag incorrectly described itself as selecting
"state data" for removal, which could mislead operators into removing
the wrong data category. This corrects the description to accurately
reflect that the flag targets chain data (block bodies and receipts).
This PR contains two changes:
Firstly, the finalized header will be resolved from local chain if it's
not recently announced via the `engine_newPayload`.
What's more importantly is, in the downloader, originally there are two
code paths to push forward the pivot point block, one in the beacon
header fetcher (`fetchHeaders`), and another one is in the snap content
processer (`processSnapSyncContent`).
Usually if there are new blocks and local pivot block becomes stale, it
will firstly be detected by the `fetchHeaders`. `processSnapSyncContent`
is fully driven by the beacon headers and will only detect the stale pivot
block after synchronizing the corresponding chain segment. I think the
detection here is redundant and useless.
We got a report for a bug in the tracing journal which has the
responsibility to emit events for all state that must be reverted.
The edge case is as follows: on CREATE operations the nonce is
incremented. When a create frame reverts, the nonce increment associated
with it does **not** revert. This works fine on master. Now one step
further: if the parent frame reverts tho, the nonce **should** revert
and there is the bug.
This PR fixes a regression introduced in https://github.com/ethereum/go-ethereum/pull/33836/changes
Before PR 33836, running mainnet would automatically bump the cache size
to 4GB and trigger a cache re-calculation, specifically setting the key-value
database cache to 2GB.
After PR 33836, this logic was removed, and the cache value is no longer
recomputed if no command line flags are specified. The default key-value
database cache is 512MB.
This PR bumps the default key-value database cache size alongside the
default cache size for other components (such as snapshot) accordingly.
I observed failing tests in Hive `engine-withdrawals`:
-

```shell
DEBUG (Withdrawals Fork on Block 2): NextPayloadID before getPayloadV2:

<< error: {"code":-38005,"message":"Unsupported fork"}
FAIL: Expected no error on EngineGetPayloadV2: error=Unsupported fork
```
The same failure pattern occurred for Block 3.
Per Shanghai engine_getPayloadV2 spec, pre-Shanghai payloads should be
accepted via V2 and returned as ExecutionPayloadV1:
- executionPayload: ExecutionPayloadV1 | ExecutionPayloadV2
- ExecutionPayloadV1 MUST be returned if payload timestamp < Shanghai
timestamp
- ExecutionPayloadV2 MUST be returned if payload timestamp >= Shanghai
timestamp
Reference:
-
https://github.com/ethereum/execution-apis/blob/main/src/engine/shanghai.md#engine_getpayloadv2
Current implementation only allows GetPayloadV2 on the Shanghai fork
window (`[]forks.Fork{forks.Shanghai}`), so pre-Shanghai payloads are
rejected with Unsupported fork.
If my interpretation of the spec is incorrect, please let me know and I
can adjust accordingly.

`GenerateChain` commits trie nodes asynchronously, and it can happen
that some nodes aren't making it to the db in time for `GenerateChain`
to open it and find the data it is looking for.
This is an optimization that existed for verkle and the MPT, but that
got dropped during the rebase.
Mark the nodes that were modified as needing recomputation, and skip the
hash computation if this is not needed. Otherwise, the whole tree is
hashed, which kills performance.
The computation of `MAIN_STORAGE_OFFSET` was incorrect, causing the last
byte of the stem to be dropped. This means that there would be a
collision in the hash computation (at the preimage level, not a hash
collision of course) if two keys were only differing at byte 31.
Eth currently has a flaky test, related to the tx fetcher.
The issue seems to happen when Unsubscribe is called while sub is nil.
It seems that chain.Stop() may be invoked before the loop starts in some
tests, but the exact cause is still under investigation through repeated
runs. I think this change will at least prevent the error.
The BatchSpanProcessor queue size was incorrectly set to
DefaultMaxExportBatchSize (512) instead of DefaultMaxQueueSize (2048).
I noticed the issue on bloatnet when analyzing the block building
traces. During a particular run, the miner was including 1000
transactions in a single block. When telemetry is enabled, the miner
creates a span for each transaction added to the block. With the queue
capped at 512, spans were silently dropped when production outpaced the
span export, resulting in incomplete traces with orphaned spans. While
this doesn't eliminate the possibility of drops under extreme
load, using the correct default restores the 4x buffer between queue
capacity and export batch size that the SDK was designed around.
