* eth/filters: uninstall subscription in filter apis on error (ethereum#32894)

Fix ethereum#32893.

In the previous ethereum#32794, it
only handles the pending tx filter, while there are also head and log
filters. This PR applies the patch to all filter APIs and uses `defer`
to maintain code consistency.

* triedb, core/rawdb: implement the partial read in freezer (ethereum#32132)

This PR implements the partial read functionalities in the freezer, optimizing

* cmd/workload: filter fuzzer test (ethereum#31613)

This PR adds a `filterfuzz` subcommand to the workload tester that
generates requests similarly to `filtergen` (though with a much smaller
block length limit) and also verifies the results by retrieving all
block receipts in the range and locally filtering out relevant results.
Unlike `filtergen` that operates on the finalized chain range only,
`filterfuzz` does check the head region, actually it seeds a new query
at every new chain head.

* triedb/pathdb: catch int conversion overflow in 32-bit (ethereum#32899)

The limit check for `MaxUint32` is done after the cast to `int`. On 64
bits machines, that will work without a problem. On 32 bits machines,
that will always fail. The compiler catches it and refuses to build.

Note that this only fixes the compiler build. ~~If the limit is above
`MaxInt32` but strictly below `MaxUint32` then this will fail at runtime
and we have another issue.~~ I checked and this should not happen during
regular execution, although it might happen in tests.

* p2p/discover: remove hot-spin in table refresh trigger (ethereum#32912)

This fixes a regression introduced in ethereum#32518. In that PR, we removed the
slowdown logic that would throttle lookups when the table runs empty.
Said logic was originally added in ethereum#20389.

Usually it's fine, but there exist pathological cases, such as hive
tests, where the node can only discover one other node, so it can only
ever query that node and won't get any results. In cases like these, we
need to throttle the creation of lookups to avoid crazy CPU usage.

These metrics help with monitoring and evaluating the need for future

Additionally, this PR moves the fetcher metrics into a separate file, 
`eth/fetcher/metrics.go`.

_Note that this PR doesn't implement the stateful keccak state

since this is what is used in the tree root computation. The runtime
doesn't currently export the sponge. I will see if I can fix that in a
further PR, but it is going to take more time. In the meantime, this is

`Genesis` object in the same path that the other network flags currently
work in.

Question: is something like `--genesis` enough to start deprecating
`geth init`?

In `testClientCancel` we wrap the server listener in `flakeyListener`,
which schedules an unconditional close of every accepted connection
after a random delay, if the random delay is zero then the timer fires
immediately, and then the http client paniced of connection reset by
peer.

Here we add a minimum 10ms to ensure the timeout won't fire immediately.

* core/rawdb, triedb/pathdb: re-structure the trienode history header (ethereum#32907)

In this PR, several changes have been made:

(a) restructure the trienode history header section

Previously, the offsets of the key and value sections were recorded before 
encoding data into these sections. As a result, these offsets referred to the
start position of each chunk rather than the end position.

This caused an issue where the end position of the last chunk was
unknown, making it incompatible with the freezer partial-read APIs. 
With this update, all offsets now refer to the end position, and the 
start position of the first chunk is always 0.

(b) Enable partial freezer read for trienode data retrieval

The partial freezer read feature is now utilized in trienode data
retrieval, improving efficiency.

When a parent block is sealed late (actual seal time exceeds its timestamp), the next block had insufficient time to include transactions, resulting in empty blocks.

Problem:
- Parent block timestamp: T=2s, sealed at T=4s (2s late)
- Next block gets timestamp: parent + period = 4s
- Current time: 4s
- Build time available: 0s → empty block

Solution:
Set header.Time = now + blockPeriod when scheduled time has passed, giving blocks full build time regardless of parent seal latency.

* txpool: add stuck transaction rebroadcast mechanism (ethereum#1992)

* txpool: add stuck transaction rebroadcast mechanism

When transactions are broadcast to peers, they're marked as "known" in each peer's knownTxs cache. If the network send fails or the peer fails to request transaction body, the peer will never receive the transaction but the hash remains in knownTxs, preventing future rebroadcasts and causing transactions to get stuck.

This change adds a periodic rebroadcast mechanism that:
- Identifies immediately executable transactions older than RebroadcastInterval but younger than RebroadcastMaxAge
- Clears their hashes from peers' knownTxs caches
- Rebroadcasts them to the network

* consensus/bor: fix goroutine leak in runMilestoneFetcher when Heimdall is unreachable (ethereum#2056)

FetchMilestone was called with context.Background(), which has no deadline. When Heimdall becomes unreachable, FetchWithRetry enters an infinite retry loop that never returns. Since the ticker fires every second, a new blocked goroutine accumulates each tick — leading to OOM within minutes.

Add a 30s context timeout to bound each call, matching the existing pattern in retryHeimdallHandler (eth/backend.go). This caps in-flight goroutines at ~30 instead of growing unboundedly.

* consensus/bor: fix sub-second late block detection producing empty blocks (ethereum#2060)

The late-block adjustment in Prepare() uses an integer-second comparison
(header.Time < now.Unix()) to detect when a block is behind schedule and
needs additional build time. Because header.Time is an integer (seconds)
while the actual target time can have sub-second precision, a block can
be up to 999ms late without triggering the adjustment.

Example: with period=1s and parent.Time=T:

  header.Time        = T + 1                     (integer seconds)
  now                = T + 1.820                  (parent block is 820ms late)
  now.Unix()         = T + 1                      (truncated to seconds)
  header.Time < now.Unix() → false                (adjustment skipped!)

This affects both the default path (blockTime=0, where GetActualTime()
falls back to time.Unix(header.Time, 0)) and the custom blockTime path
(where ActualTime has sub-second precision from the parent cache chain).

With no adjustment, GetActualTime() returns a time already in the past.
The interrupt timer in commitWork() expires immediately, which sets the
interruptBlockBuilding flag before fillTransactions() runs. The txpool's
Pending() checks this flag on every address iteration and returns an
empty map, producing a block with 0 transactions even when the pool has
pending transactions.

Fix by replacing the integer comparison with a direct time comparison
against the block's actual target time:

  if now.After(header.GetActualTime()) {

GetActualTime() returns header.ActualTime when set (custom blockTime
with Rio, sub-second precision), or time.Unix(header.Time, 0) as
fallback (default path). This correctly detects lateness in both cases
without over-triggering for on-time blocks, since on-time blocks have
their target time in the future.
