This PR fixes what https://github.com/ethereum/go-ethereum/pull/30306/

Remove redundant address presence check in `makeGasSStoreFunc`.
This PR simplifies the `makeGasSStoreFunc` function by removing the
redundant check for address presence in the access list. The updated
code now only checks for slot presence, streamlining the logic and
eliminating unnecessary panic conditions.
This change removes the unnecessary address presence check, simplifying
the code and improving maintainability without affecting functionality.
The previous panic condition was intended as a canary during the testing
phases (i.e. _YOLOv2_) and is no longer needed.
h/t @MariusVanDerWijden for finding and fixing this on devnet 3.
I made the mistake of thinking `PayloadVersion` was correlated with the
`GetPayloadVX` method, but it actually tracks which version of
`PayloadAttributes` were passed to `forkchoiceUpdated`. So far, Prague
does not necessitate a new version of fcu, so there is no need for
`PayloadV4`.

#29995 has been reverted due to an unexpected flaw in the state snapshot
process.
Specifically, it attempts to stop the state snapshot generation, which
could potentially
cause the system to halt if the generation is not currently running.
This pull request ports the changes made in #29995 and fixes the flaw.
This PR fixes an issue with blob transaction propagation due to the blob
transation txpool rejecting transactions with gapped nonces. The
specific changes are:
- fetch transactions from a peer in the order they were announced to
minimize nonce-gaps (which cause blob txs to be rejected
- don't wait on fetching blob transactions after announcement is
received, since they are not broadcast
Testing:
- unit tests updated to reflect that fetch order should always match tx
announcement order
- unit test added to confirm blob transactions are scheduled immediately
for fetching
- running the PR on an eth mainnet full node without incident so far

This is a successor PR to #25743. This PR is based on a new iteration of
the spec: https://github.com/ethereum/execution-apis/pull/484.
`eth_multicall` takes in a list of blocks, each optionally overriding
fields like number, timestamp, etc. of a base block. Each block can
include calls. At each block users can override the state. There are
extra features, such as:
- Include ether transfers as part of the logs
- Overriding precompile codes with evm bytecode
- Redirecting accounts to another address
## Breaking changes
This PR includes the following breaking changes:
- Block override fields of eth_call and debug_traceCall have had the
following fields renamed
- `coinbase` -> `feeRecipient`
- `random` -> `prevRandao`
- `baseFee` -> `baseFeePerGas`

This pull request replaces the field pointer in journal entry with the
field itself, specifically the address of mutated account.
While it will introduce the extra allocation cost, but it's easier for
code reading. Let's measure the overhead overall to see if the change is
acceptable or not.
This pull request introduces a state.Reader interface for state
accessing.
The interface could be implemented in various ways. It can be pure trie
only reader, or the combination of trie and state snapshot. What's more,
this interface allows us to have more flexibility in the future, e.g.
the
archive reader (for accessing archive state).
Additionally, this pull request removes the following metrics
- `chain/snapshot/account/reads`
- `chain/snapshot/storage/reads`
This PR fixes a flaky jwt-test.
The test is a jwt "from one second in the future". The test passes; the
reason for this is that the CI-system is slow, and by the time the jwt
is actually evaluated, that second has passed, and it's no longer
future.
Alternative to #30380
This PR changes how sidechains are handled.
Before the merge, it was possible to import a chain with lower td and not set it as canonical. After the merge, we expect every chain that we get via InsertChain to be canonical. Non-canonical blocks can still be inserted
with InsertBlockWIthoutSetHead.
If during the InsertChain, the existing chain is not canonical anymore, we mark it as a sidechain and send the SideChainEvents normally.
This pull request fixes a flaw in prefetcher.
In verkle tree world, both accounts and storage slots are committed into
a single tree instance for state hashing. If the prefetcher is activated, we will
try to pull the trie for the prefetcher for performance speedup.
However, we had a special logic to skip pulling storage trie if the
storage root is empty. While it's true for merkle as we have nothing to
do with an empty storage trie, it's totally wrong for verkle. The consequences
for skipping pulling is the storage changes are committed into trie A, while the
account changes are committed into trie B (pulled from the prefetcher), boom.
This PR adds the bulk verkle witness+proof production at the end of block
production. It reads all data from the tree in one swoop and produces
a verkle proof.

When attempting to hash a typed data struct that includes a type
reference with a fixed-size array, the validation process fails.
According to EIP-712, arrays can be either fixed-size or dynamic,
denoted by `Type[n]` or `Type[]` respectively, although it appears this
currently isn't supported.
This change modifies the validation logic to accommodate types
containing fixed-size arrays.
This is a follow-up to #29520, and a preparatory PR to a more thorough
change in the journalling system.
### API methods instead of `append` operations
This PR hides the journal-implementation details away, so that the
statedb invokes methods like `JournalCreate`, instead of explicitly
appending journal-events in a list. This means that it's up to the
journal whether to implement it as a sequence of events or
aggregate/merge events.
### Snapshot-management inside the journal
This PR also makes it so that management of valid snapshots is moved
inside the journal, exposed via the methods `Snapshot() int` and
`RevertToSnapshot(revid int, s *StateDB)`.
### SetCode
JournalSetCode journals the setting of code: it is implicit that the
previous values were "no code" and emptyCodeHash. Therefore, we can
simplify the setCode journal.
### Selfdestruct
The self-destruct journalling is a bit strange: we allow the
selfdestruct operation to be journalled several times. This makes it so
that we also are forced to store whether the account was already
destructed.
What we can do instead, is to only journal the first destruction, and
after that only journal balance-changes, but not journal the
selfdestruct itself.
This simplifies the journalling, so that internals about state
management does not leak into the journal-API.
### Preimages
Preimages were, for some reason, integrated into the journal management,
despite not being a consensus-critical data structure. This PR undoes
that.

In few tests the returned error from `SendTransaction` is not being
checked. This PR checks the returned err in tests.
Returning errors also revealed tx in `TestCommitReturnValue` is not
actually being sent, and returns err ` only replay-protected (EIP-155)
transactions allowed over RPC`. Fixed the transaction by using the
`testTx` function.
`WriteToUDP` was never called, since `meteredUdpConn` exposed directly
all the methods from the underlying `UDPConn` interface.
This fixes the `discover/egress` metric never being updated.
This pull request adds a few more performance metrics, specifically:
- The average time cost of an account read
- The average time cost of a storage read
- The rate of account reads
- The rate of storage reads
This is a performance improvement on the account-creation rollback code
required for the archive node to support verkle. It uses the utility
function `DeleteAtStem` to remove code and account data per-group
instead of doing it leaf by leaf.
It also fixes an index bug, as code is chunked in 31-byte chunks, so
comparing with the code size should use 31 as its stride.

This PR adds the `dns:read` and `dns:edit` permissions to the required
set of permissions checked before deploying an ENR tree to Cloudflare.
These permissions are necessary for a successful publish.
**Background**:
The current logic for `devp2p dns to-cloudflare` checks for `zone:edit`
and `zone:read` permissions. However, when running the command with only
these two permissions, the following error occurs:
```
wrong permissions on zone REMOVED-ZONE: map[#zone:edit:false #zone:read:true]
```
Adding `zone:read` and `zone:edit` to the API token led to a different
error:
```
INFO [08-19|14:06:16.782] Retrieving existing TXT records on pos-nodes.hardfork.dev
Authentication error (10000)
```
This suggested that additional permissions were required. I added
`dns:read`, but encountered another error:
```
INFO [08-19|14:11:42.342] Retrieving existing TXT records on pos-nodes.hardfork.dev
INFO [08-19|14:11:42.851] Updating DNS entries
failed to publish REMOVED.pos-nodes.hardfork.dev: Authentication error (10000)
```
Finally, after adding both `dns:read` and `dns:edit` permissions, the
command executed successfully with the following output:
```
INFO [08-19|14:13:07.677] Checking Permissions on zone REMOVED-ZONE

With this PR, the required permissions for deploying an ENR tree to
Cloudflare now include `zone:read`, `zone:edit`, `dns:read`, and
`dns:edit`. The initial check now includes all of the necessary
permissions and indicates in the error message which permissions are
missing:
```

This PR updates the version of go used in builds and docker to
1.23.0. Release notes: https://go.dev/doc/go1.23
More importantly, following our policy of maintaining the last two
versions (which now becomes 1.23 and 1.22), we can now make use of
the things that were introduced in 1.22: https://go.dev/doc/go1.22
Go 1.22 makes two changes to “for” loops.
- each iteration creates new variables,
- for loops may range over integers
Other than that, some interesting library changes and other stuff.
This PR implements the conclusions from
https://github.com/ethereum/go-ethereum/issues/28987#issuecomment-2296075028,
that is:
Building with `--strip-all` as a ld-flag to the cgo linker, to remove
symbols. Without that, some spurious reference to a temporary file is
included into the kzg-related library.
Building with `--build-id=none`, to avoid putting a `build id` into the file.
closes#29475, replaces #29657, #30104
Fixes two issues. First is a deadlock where the txpool attempts to reorg, but can't complete because there are no readers left for the new txs subscription. Second, resolves a problem with on demand mode where txs may be left pending when there are more pending txs than block space.

Our `WriteArchive`, used by ci builder, creates files in the repo root,in order to upload. After we've built the amd64-builds, we create the uploads, and cause the repo to be flagged as dirty for the remaining builds.
This change fixes it by adding the artefacts to gitignore. Closes#30324
When we are building in detached head, we cannot easily obtain the same information as we can if we're in non-detached head.
However, one thing we _can_ obtain is the git-hash and git-date. Currently, we omit to include the git-date into the build-info, which causes problem for reproducable builds which are on a detached head.
This change fixes it to include the date-info always.
To allow all error paths in `vm.EVM.create()` to consume the necessary
gas, there is currently a pattern of gating code on `if err == nil`
instead of returning as soon as the error occurs. The same behaviour can
be achieved by abstracting the gated code into a method that returns
immediately on error, improving readability and thus making it easier to
understand and maintain.
Here I am adding a discv5 nodes source into the p2p dial iterator. It's
an improved version of #29533.
Unlike discv4, the discv5 random nodes iterator will always provide full
ENRs. This means we can apply filtering to the results and will only try
dialing nodes which explictly opt into the eth protocol with a matching
chain.
I have also removed the dial iterator from snap. We don't have an
official DNS list for snap anymore, and I doubt anyone else is running
one. While we could potentially filter for snap on discv5, there will be
very few nodes announcing it, and the extra iterator would just stall
the dialer.

Add coinbase address to javascript tracer context.
This PR adds the `coinbase` address to `jsTracer.ctx`, allowing access
to the coinbase address (fee receipient) in custom JavaScript tracers.
Example usage:
```javascript

return toAddress(ctx.coinbase);
}
```
This change enables custom tracers to access coinbase address,
previously unavailable, enhancing their capabilities to match built-in
tracers.

This pull request fixes#30229.
During snap sync, large storage will be split into several pieces and
synchronized concurrently. Unfortunately, the tradeoff is that the respective
merkle trie of each storage chunk will be incomplete due to the incomplete
boundaries. The trie nodes on these boundaries will be discarded, and any
dangling nodes on disk will also be removed if they fall on these paths,
ensuring the state healer won't be blocked.
However, the dangling account trie nodes on the path from the root to the
associated account are left untouched. This means the dangling account trie
nodes could potentially stop the state healing and break the assumption that the
entire subtrie should exist if the subtrie root exists. We should consider the
account trie node as the ancestor of the corresponding storage trie node.
In the scenarios described in the above ticket, the state corruption could occur
if there is a dangling account trie node while some storage trie nodes are
removed due to synchronization redo.
The fixing idea is pretty straightforward, the trie nodes on the path from root
to account should all be explicitly removed if an incomplete storage trie
occurs. Therefore, a `delete` operation has been added into `gentrie` to
explicitly clear the account along with all nodes on this path. The special
thing is that it's a cross-trie clearing. In theory, there may be a dangling
node at any position on this account key and we have to clear all of them.

Some chains’ network IDs use hexadecimal such as Optimism ("0xa" instead
of "10"), so when converting the string to big.Int, we cannot specify
base 10; otherwise, it will encounter errors with hexadecimal network
IDs.
The struct-based tracing added in #29189 seems to have caused an issue
with the benchmark `BenchmarkTracerStepVsCallFrame`. On master we see
the following panic:

The issue seems to be that `OnOpcode` expects that `OnTxStart` has
already been called to initialize the `env` value in the tracer. The JS
tracer uses it in `OnOpcode` for the `GetRefund()` method.
This patch resolves the issue by reusing the `Call` method already
defined in `runtime_test.go` which correctly calls `OnTxStart`.
Fixes#30254
It seems like the removed CreateAccount call is very old and not needed anymore.
After removing it, setting a sender that does not exist in the state doesn't seem to cause

Adding the correct accessList parameter when calling a contract can

the accessList manually when constructing the transaction. This PR can

This PR fixes an issue in the setMode method of beaconBackfiller where the
log message was not displaying the previous mode correctly. The log message
now shows both the old and new sync modes.
## Issue
If `nextTime` has passed, but all nodes are excluded, `get` would return
`nil` and `run` would therefore not invoke `schedule`. Then, we schedule
a timer for the past, as neither `nextTime` value has been updated. This
creates a busy loop, as the timer immediately returns.
## Fix
With this PR, revalidation will be also rescheduled when all nodes are
excluded.

The test specifies `ListenAddr: ":0"`, which means a random ephemeral
port will be chosen for the TCP listener by the OS. Additionally, since
no `DiscAddr` was specified, the same port that is chosen automatically
by the OS will also be used for the UDP listener in the discovery UDP
setup. This sometimes leads to test failures if the TCP listener picks a
free TCP port that is already taken for UDP. By specifying `DiscAddr:
":0"`, the UDP port will be chosen independently from the TCP port,
fixing the random failure.
See issue #29830.
Verified using
```
cd p2p
go test -c -race
stress ./p2p.test -test.run=TestServerPortMapping
...
5m0s: 4556 runs so far, 0 failures
```
The issue described above can technically lead to sporadic failures on
systems that specify a listen address via the `--port` flag of 0 while
not setting `--discovery.port`. Since the default is using port `30303`
and using a random ephemeral port is likely not used much to begin with,
not addressing the root cause might be acceptable.
This pull request fixes the broken feature where the entire storage set is overridden.
Originally, the storage set override was achieved by marking the associated account
as deleted, preventing access to the storage slot on disk. However, since #29520, this
flag is also checked when accessing the account, rendering the account unreachable.
A fix has been applied in this pull request, which re-creates a new state object with all
account metadata inherited.
Currently, we have 3 flags to configure blob pool. However, we don't
read these flags and set the blob pool configuration in eth config
accordingly. This commit adds a function to check if these flags are
provided and set blob pool configuration based on them.
This pull request adds an additional error check after statedb.IntermediateRoot,
ensuring that no errors occur during this call. This step is essential, as the call might
encounter database errors.
The address recover is executed and cached in ValidateTransaction already. It's
expected that the cached one is returned in ValidateTransaction. However,
currently, we use the wrong function signer.Sender instead of types.Sender which
will do all the address recover again.
Here we add distinct error messages for network timeouts and JSON parsing errors.
Note this specifically applies to HTTP connections serving a single RPC request.

Since account self-destruction was deprecated with the Cancun fork,

This does not change the behavior here as the nonce in the argument is
tx.Nonce(). This commit helps to make the function easier to read and avoid

enode.Node was recently changed to store a cache of endpoint information. The IP address in the cache is a netip.Addr. I chose that type over net.IP because it is just better. netip.Addr is meant to be used as a value type. Copying it does not allocate, it can be compared with ==, and can be used as a map key.
This PR changes most uses of Node.IP() into Node.IPAddr(), which returns the cached value directly without allocating.
While there are still some public APIs left where net.IP is used, I have converted all code used internally by p2p/discover to the new types. So this does change some public Go API, but hopefully not APIs any external code actually uses.
There weren't supposed to be any semantic differences resulting from this refactoring, however it does introduce one: In package p2p/netutil we treated the 0.0.0.0/8 network (addresses 0.x.y.z) as LAN, but netip.Addr.IsPrivate() doesn't. The treatment of this particular IP address range is controversial, with some software supporting it and others not. IANA lists it as special-purpose and invalid as a destination for a long time, so I don't know why I put it into the LAN list. It has now been marked as special in p2p/netutil as well.
This pull request fixes the pre-order trie traversal by defining

This should fix an occasional test failure in ethclient/simulated.TestForkResendTx.
Inspection of logs revealed the cause of the failure to be that the txpool was not done
reorganizing by the time Fork is called.
Here we clean up internal uses of type discover.node, converting most code to use
enode.Node instead. The discover.node type used to be the canonical representation of
network hosts before ENR was introduced. Most code worked with *node to avoid conversions
when interacting with Table methods. Since *node also contains internal state of Table and
is a mutable type, using *node outside of Table code is prone to data races. It's also
cleaner not having to wrap/unwrap *enode.Node all the time.
discover.node has been renamed to tableNode to clarify its purpose.
While here, we also change most uses of net.UDPAddr into netip.AddrPort. While this is
technically a separate refactoring from the *node -> *enode.Node change, it is more
convenient because *enode.Node handles IP addresses as netip.Addr. The switch to package
netip in discovery would've happened very soon anyway.
The change to netip.AddrPort stops at certain interface points. For example, since package
p2p/netutil has not been converted to use netip.Addr yet, we still have to convert to
net.IP/net.UDPAddr in a few places.
Create the directory before NewKeyStore. This ensures the watcher successfully starts on
the first attempt, and waitWatcherStart functions as intended.
It seems the semantic differences between addFoundNode and addInboundNode were lost in
#29572. My understanding is addFoundNode is for a node you have not contacted directly
(and are unsure if is available) whereas addInboundNode is for adding nodes that have
contacted the local node and we can verify they are active.
handleAddNode seems to be the consolidation of those two methods, yet it bumps the node in
the bucket (updating it's IP addr) even if the node was not an inbound. This PR fixes
this. It wasn't originally caught in tests like TestTable_addSeenNode because the
manipulation of the node object actually modified the node value used by the test.
New logic is added to reject non-inbound updates unless the sequence number of the
(signed) ENR increases. Inbound updates, which are published by the updated node itself,
are always accepted. If an inbound update changes the endpoint, the node will be
revalidated on an expedited schedule.

In #29572, I assumed the revalidation list that the node is contained in could only ever
be changed by the outcome of a revalidation request. But turns out that's not true: if the
node gets removed due to FINDNODE failure, it will also be removed from the list it is in.
This causes a crash.
The invariant is: while node is in table, it is always in exactly one of the two lists. So
it seems best to store a pointer to the current list within the node itself.
This pull request fixes the flay test TestSkeletonSyncRetrievals. In this test, we first
trigger a sync cycle and wait for it to meet certain expectations. We then inject a new
head and potentially also a new peer, then perform another final sync. The test now
performs the newPeer addition before launching the final sync, and waits a bit for that
peer to get registered. This fixes the logic race that made the test fail sometimes.

enode.Node has separate accessor functions for getting the IP, UDP port and TCP port.
These methods performed separate checks for attributes set in the ENR.
With this PR, the accessor methods will now return cached information, and the endpoint is
determined when the node is created. The logic to determine the preferred endpoint is now
more correct, and considers how 'global' each address is when both IPv4 and IPv6 addresses
are present in the ENR.
Node discovery periodically revalidates the nodes in its table by sending PING, checking
if they are still alive. I recently noticed some issues with the implementation of this
process, which can cause strange results such as nodes dropping unexpectedly, certain
nodes not getting revalidated often enough, and bad results being returned to incoming
FINDNODE queries.
In this change, the revalidation process is improved with the following logic:
- We maintain two 'revalidation lists' containing the table nodes, named 'fast' and 'slow'.
- The process chooses random nodes from each list on a randomized interval, the interval being
faster for the 'fast' list, and performs revalidation for the chosen node.
- Whenever a node is newly inserted into the table, it goes into the 'fast' list.
Once validation passes, it transfers to the 'slow' list. If a request fails, or the
node changes endpoint, it transfers back into 'fast'.
- livenessChecks is incremented by one for successful checks. Unlike the old implementation,
we will not drop the node on the first failing check. We instead quickly decay the
livenessChecks give it another chance.
- Order of nodes in bucket doesn't matter anymore.
I am also adding a debug API endpoint to dump the node table content.

Added a start/end system where tracer can be notified that processing of some Ethereum system calls is starting processing and also notifies it when the processing has completed.
Doing a start/end for system call will enable tracers to "route" incoming next tracing events to go to a separate bucket than other EVM calls. Those not interested by this fact can simply avoid registering the hooks.
The EVM call is going to be traced normally afterward between the signals provided by those 2 new hooks but outside of a transaction context OnTxStart/End. That something implementors of live tracers will need to be aware of (since only "trx tracers" are not concerned by ProcessBeaconRoot).

This PR fixes some flaws with the existing tests.
The randomized testing (TestSnapshotRandom) executes a series of steps which modify the state and create journal-events. Later on, we compare the forward-going-states against the backwards-unrolling-journal-states, and check that they are identical.
The "identical" check is performed using various accessors. It turned out that we failed to check some things:
- the accesslist contents
- the transient storage contents
- the 'newContract' flag
- the dirty storage map
This change adds these new checks
Currently our state journal tracks each storage update to a contract, having the ability to revert those changes to the previously set value.
For the very first modification however, it behaves a bit wonky. Reverting the update doesn't actually remove the dirty-ness of the slot, rather leaves it as "change this slot to it's original value". This can cause issues down the line with for example write witnesses needing to gather an unneeded proof.
This PR modifies the storageChange journal entry to not only track the previous value of a slot, but also whether there was any previous value at all set in the current execution context. In essence, the PR changes the semantic of storageChange so it does not simply track storage changes, rather it tracks dirty storage changes, an important distinction for being able to cleanly revert the journal item.
This change adds a testcase and fixes a corner-case in the skeleton sync.
With this change, when doing the skeleton cleanup, we check if the filled header is acually within the range of what we were meant to backfill. If not, it means the backfill was a noop (possibly because we started and stopped it so quickly that it didn't have time to do any meaningful work). In that case, just don't clean up anything.

The beacon root when applied in `state_processor.go` is performed right before executing transaction. That means that contract reliying on this value would query the same value found in the block header.
In that spirit, it means that any tracing/operation relying on state data which touches transaction must have updated the beacon root before any transaction processing.
This PR adds an extra mechanism to sync.HeadSync that tries to retrieve the latest finality update from every server each time it sends an optimistic update in a new epoch (unless we already have a validated finality update attested in the same epoch).
Note that this is not necessary and does not happen if the new finality update is delivered before the optimistic update. The spec only mandates light_client_finality_update events when a new epoch is finalized. If the chain does not finalize for a while then we might need an explicit request that returns a finality proof that proves the same finality epoch from the latest attested epoch.
This change fixes three flaky tests `TestEth2AssembleBlock`,`TestEth2NewBlock`, `TestEth2PrepareAndGetPayload` and `TestDisable`.

This change removes support for subscribing to pending logs.
"Pending logs" were always an odd feature, because it can never be fully reliable. When support for it was added many years ago, the intention was for this to be used by wallet apps to show the 'potential future token balance' of accounts, i.e. as a way of notifying the user of incoming transfers before they were mined. In order to generate the pending logs, the node must pick a subset of all public mempool transactions, execute them in the EVM, and then dispatch the resulting logs to API consumers.
This PR updates the bls contracts from our internal implementation which is an unmaintained fork of the kilic library to the gnark-crypto library that is actively maintained by consensys.
It also updates the gas-costs according to the EIP
This pull request defines a gentrie for snap sync purpose.
The stackTrie is used to generate the merkle tree nodes upon receiving a state batch. Several additional options have been added into stackTrie to handle incomplete states (either missing states before or after).
In this pull request, these options have been relocated from stackTrie to genTrie, which serves as a wrapper for stackTrie specifically for snap sync purposes.
Further, the logic for managing incomplete state has been enhanced in this change. Originally, there are two cases handled:
- boundary node filtering
- internal (covered by extension node) node clearing
This changes adds one more:
- Clearing leftover nodes on the boundaries.
This feature is necessary if there are leftover trie nodes in database, otherwise node inconsistency may break the state healing.
time.After is equivalent to NewTimer(d).C, and does not call Stop if the timer is no longer needed. This can cause memory leaks. This change changes many such occations to use NewTimer instead, and calling Stop once the timer is no longer needed.

This addresses an edge-case (detailed in the code comment) where the computation of the intermediate trie root would force the unnecessary resolution of a hash node. The change makes it so that when we process changes from a block, we first process trie-updates and afterwards process trie-deletions.
Before, `ToMessage` was returning both the resulting `Message` and an error while no error is returned now.
Those error checks were probably leftover from the past.
The StartHeadListener method will only be called once. So it can't just make one attempt
to connect to the eventsource endpoint, it has to keep trying. Note that once the stream
is established, the eventsource implementation itself will keep retrying.
Here we add a Go API for running tracing plugins within the main block import process.
As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.
The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of
requiring an interface, for several reasons:
- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
to implement only the hooks you want to actually use.
All existing tracers in eth/tracers/native have been rewritten to use the new hook system.
This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

This pull request introduces a database tool for inspecting the state history.
It can be used for either account history or storage slot history, within a
specific block range.
The state output format can be chosen either with
- the "rlp-encoded" values (those inserted into the merkle trie)
- the "rlp-decoded" value (the raw state value)
The latter one needs --raw flag.

Here we add a beacon chain light client for use by geth.
Geth can now be configured to run against a beacon chain API endpoint,
without pointing a CL to it. To set this up, use the `--beacon.api` flag. Information
provided by the beacon chain is verified, i.e. geth does not blindly trust the beacon
API endpoint in this mode. The root of trust are the beacon chain 'sync committees'.
The configured beacon API endpoint must provide light client data. At this time, only
Lodestar and Nimbus provide the necessary APIs.
There is also a standalone tool, cmd/blsync, which uses the beacon chain light client
to drive any EL implementation via its engine API.

As SELF-DESTRUCT opcode is disabled in the cancun fork(unless the
account is created within the same transaction, nothing to delete
in this case). The account will only be deleted in the following
cases:
- The account is created within the same transaction. In this case
the original storage was empty.
- The account is empty(zero nonce, zero balance, zero code) and
is touched within the transaction. Fortunately this kind of accounts
are not-existent on ethereum-mainnet.
All in all, after cancun, we are pretty sure there is no large contract
deletion and we don't need this mechanism for oom protection.
The prestateTracer was reporting an inaccurate nonce for the contract being created in
post EIP-158 transactions. Correct nonce is 0, due to the issue nonce was being reported as 1.

This PR enhances eth_createAccessList RPC call to support scenarios where the node is launched with an unlimited gas cap (--rpc.gascap 0). The eth_createAccessList RPC call returns failure if user doesn't explicitly set a gas limit.

This pull request fixes a flaw in ethstats which can lead to node crash
A panic could happens when the local blockchain is reorging which causes the original head block not to be reachable (since number->hash canonical mapping is deleted). In order to prevent the panic, the block nilness is now checked in ethstats.
Improving two things here:
On hive, where we look at these tests, the Go code comment above the test
is not visible. When there is a failure, it's not obvious what the test is actually
expecting. I have converted the comments in to printed log messages to
explain the test more.
Second, I noticed that besu is failing some tests because it happens to request
a header when we want it to send transactions. Trying the minimal fix here to
serve the headers.

At some point, `ForkchoiceUpdatedV2` stopped working for `PayloadAttributesV1` while `paris` was active. This was causing a few failures in hive. This PR fixes that, and also adds a gate in `ForkchoiceUpdatedV1` to disallow `PayloadAttributesV3`.
GetPayloadVX should only return payloads which match its version. GetPayloadV2 is a special snowflake that supports v1 and v2 payloads. This change uses a a version-specific prefix within in the payload id, basically a namespace for the version number.
This PR fixes an issues in the new simulated backend. The root cause is the fact that the transaction pool has an internal reset operation that runs on a background thread.
When a new transaction is added to the pool via the RPC, the transaction is added to a non-executable queue and will be moved to its final location on a background thread. If the machine is overloaded (or simply due to timing issues), it can happen that the simulated backend will try to produce the next block, whilst the pool has not yet marked the newly added transaction executable. This will cause the block to not contain the transaction. This is an issue because we want determinism from the simulator: add a tx, mine a block. It should be in there.
The PR fixes it by adding a Sync function to the txpool, which waits for the current reset operation (if any) to finish, and then runs an entire round of reset on top. The new round is needed because resets are only triggered by new head events, so newly added transactions will not trigger the outer resets that we can wait on. The transaction pool would eventually internally do a reset even on transaction addition, but there's no easy way to wait on that and there's no meaningful reason to bubble that across everything. A clean outer reset will at worse be a small noop goroutine.
This PR introduces a few changes with respect to payload verification in fcu and new payload requests:
* First of all, it undoes the `verifyPayloadAttributes(..)` simplification I attempted in #27872.
* Adds timestamp validation to fcu payload attributes [as required](https://github.com/ethereum/execution-apis/blob/main/src/engine/cancun.md#specification-1) (section 2) by the Engine API spec.
* For the new payload methods, I also update the verification of the executable data. For `newPayloadV2`, it does not currently ensure that cancun values are `nil`. Which could make it possible to submit cancun payloads through it.
* On `newPayloadV3` the same types of checks are added. All shanghai and cancun related fields in the executable data must be non-nil, with the addition that the timestamp is _only_ with cancun.
* Finally it updates a newly failing catalyst test to call the correct fcu and new payload methods depending on the fork.
This change switches from using the `Hasher` interface to add/query the bloomfilter to implementing it as methods.
This significantly reduces the allocations for Search and Rebloom.
This change makes use of uin256 to represent balance in state. It touches primarily upon statedb, stateobject and state processing, trying to avoid changes in transaction pools, core types, rpc and tracers.
This change simplifies the logic for indexing transactions and enhances the UX when transaction is not found by returning more information to users.
Transaction indexing is now considered as a part of the initial sync, and `eth.syncing` will thus be `true` if transaction indexing is not yet finished. API consumers can use the syncing status to determine if the node is ready to serve users.
The code to compute a versioned hash was duplicated a couple times, and also had a small
issue: if we ever change params.BlobTxHashVersion, it will most likely also cause changes
to the actual hash computation. So it's a bit useless to have this constant in params.
EIP-4844 adds a new transaction type for blobs. Users can submit such transactions via `eth_sendRawTransaction`. In this PR we refrain from adding support to `eth_sendTransaction` and in fact it will fail if the user passes in a blob hash.
However since the chain can handle such transactions it makes sense to allow simulating them. E.g. an L2 operator should be able to simulate submitting a rollup blob and updating the L2 state. Most methods that take in a transaction object should recognize blobs. The change boils down to adding `blobVersionedHashes` and `maxFeePerBlobGas` to `TransactionArgs`. In summary:
- `eth_sendTransaction`: will fail for blob txes
- `eth_signTransaction`: will fail for blob txes
The methods that sign txes does not, as of this PR, add support the for new EIP-4844 transaction types. Resuming the summary:
- `eth_sendRawTransaction`: can send blob txes
- `eth_fillTransaction`: will fill in a blob tx. Note: here we simply fill in normal transaction fields + possibly `maxFeePerBlobGas` when blobs are present. One can imagine a more elaborate set-up where users can submit blobs themselves and we fill in proofs and commitments and such. Left for future PRs if desired.
- `eth_call`: can simulate blob messages
- `eth_estimateGas`: blobs have no effect here. They have a separate unit of gas which is not tunable in the transaction.
In the tracing tests, the base fee was generally set to nil. This commit changes this to pass the proper base instead, and fixes the few tests which become broken by the change.
Given the discussions around deprecating pending (see #28623 or ethereum/execution-apis#495), we can move away from using the pending block internally, and use latest instead
* accounts, ethclient: minor tweaks on the new simulated backend
* ethclient/simulated: add an initial batch of gas options

This is a rewrite of the 'simulated backend', an implementation of the ethclient interfaces
which is backed by a simulated blockchain. It was getting annoying to maintain the old
version of the simulated backend feature because there was a lot of code duplication with
the main client.
The new version is built using parts that we already have: an in-memory geth node instance
running in developer mode provides the chain, while the Go API is provided by ethclient.
A backwards-compatibility wrapper is provided, but the simulated backend has also moved to
a more sensible import path: github.com/ethereum/go-ethereum/ethclient/simulated

When managing geth, it is sometimes desirable to do a partial wipe; deleting state but retaining freezer data. A partial wipe can be somewhat tricky to accomplish.
This change implements the ability to perform partial wipe by making it possible to run geth removedb non-interactive, using command line options instead.
This pull request improves the condition to check if path state scheme is in use.
Originally, root node presence was used as the indicator if path scheme is used or not. However due to fact that root node will be deleted during the initial snap sync, this condition is no longer useful.
If PersistentStateID is present, it shows that we've already configured for path scheme.
Original problem was caused by #28595, where we made it so that as soon as we start to sync, the root of the disk layer is deleted. That is not wrong per se, but another part of the code uses the "presence of the root" as an init-check for the pathdb. And, since the init-check now failed, the code tried to re-initialize it which failed since a sync was already ongoing.
The total impact being: after a state-sync has begun, if the node for some reason is is shut down, it will refuse to start up again, with the error message: `Fatal: Failed to register the Ethereum service: waiting for sync.`.
This change also modifies how `geth removedb` works, so that the user is prompted for two things: `state data` and `ancient chain`. The former includes both the chaindb aswell as any state history stored in ancients.

This change fixes a problem with our non-core binaries: evm, clef, bootnode.
First of all, they failed to convert from legacy loglevels 1 to 5, to the new slog loglevels -4 to 4.
Secondly, the logging was actually setup in the init phase, and then overridden in the main. This is not needed for evm, since it used the same flag name as the main geth verbosity. Better to let the flags/internal handle the logging init.
Certain flags, such as `--rpc.txfeecap` currently do not have an env-var auto-generated for them. This change adds three missing cli flag types to the auto env-var helper function to fix this.

This fixes a database corruption issue that could occur during state healing.
When sync is aborted while certain modifications were already committed, and a
reorg occurs, the database would contain incorrect trie nodes stored by path.
These nodes need to detected/deleted in order to obtain a complete and fully correct state
after state healing.

This change implements CommitteeChain which is a key component of the beacon light client. It is a passive data structure that can validate, hold and update a chain of beacon light sync committees and updates, starting from a checkpoint that proves the starting committee through a beacon block hash, header and corresponding state. Once synced to the current sync period, CommitteeChain can also validate signed beacon headers.
The dump after state-test didn't work, the problem was an error, "Already committed", which was silently ignored.
This change re-initialises the state, so the dumping works again.
This change
- Removes interface `log.Format`,
- Removes method `log.FormatFunc`,
- unexports `TerminalHandler.TerminalFormat` formatting methods (renamed to `TerminalHandler.format`)
- removes the notion of `log.Lazy` values
The lazy handler was useful in the old log package, since it
could defer the evaluation of costly attributes until later in the
log pipeline: thus, if the logging was done at 'Trace', we could
skip evaluation if logging only was set to 'Info'.
With the move to slog, this way of deferring evaluation is no longer
needed, since slog introduced 'Enabled': the caller can thus do
the evaluate-or-not decision at the callsite, which is much more
straight-forward than dealing with lazy reflect-based evaluation.
Also, lazy evaluation would not work with 'native' slog, as in, these
two statements would be evaluated differently:
```golang
log.Info("foo", "my lazy", lazyObj)
slog.Info("foo", "my lazy", lazyObj)
```
These changes improves the performance of the non-coloured terminal formatting, _quite a lot_.

```
I tried to _somewhat_ organize the commits, but the it might still be a bit chaotic. Some core insights:
- The function `terminalHandler.Handl` uses a mutex, and writes all output immediately to 'upstream'. Thus, it can reuse a scratch-buffer every time.
- This buffer can be propagated internally, making all the internal formatters either write directly to it,
- OR, make use of the `tmp := buf.AvailableBuffer()` in some cases, where a byte buffer "extra capacity" can be temporarily used.
- The `slog` package uses `Attr` by value. It makes sense to minimize operating on them, since iterating / collecting into a new slice, iterating again etc causes copy-on-heap. Better to operate on them only once.
- If we want to do padding, it's better to copy from a constant `space`-buffer than to invoke `bytes.Repeat` every single time.
Add read locking of db lock around access to dirties cache in hashdb.Database to prevent
data race versus hashdb.Database.dereference which can modify the dirities map by deleting

This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21.
Main changes are as follows:
* removes any log handlers that were unused in the Geth codebase.
* Json, logfmt, and terminal formatters are now slog handlers.
* Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options.
* `--log.backtraceat` and `--log.debug` are removed.
The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged.
A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed.

For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did
```golang
log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true))))
```
You now instead need to do
```golang
log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true)))
```

This change fixes two type-inconsistencies in the JS tracer:
- In most places we return byte arrays as a `Uint8Array` to the tracer. However it seems we missed doing the conversion for `ctx` fields which are passed to the tracer during `result`. They are passed as simple arrays. I think Uint8Arrays are more suitable and we should change this inconsistency. Note: this will be a breaking-change. But I believe the effect is small. If we look at our tracers we see that these fields (`ctx.from`, `ctx.to`, etc.) are used in 2 ways. Passed to `toHex` which takes both array or buffer. Or the length was measured which is the same for both types.
- The `slice` taking in `int, int` params versus `memory.slice` taking `int64, int64` params. I suggest changing `slice` types to `int64`. This should have no effect almost in any case.
There were several problems related to dumping state.
- If a preimage was missing, even if we had set the `OnlyWithAddresses` to `false`, to export them anyway, the way the mapping was constructed (using `common.Address` as key) made the entries get lost anyway. Concerns both state- and blockchain tests.
- Blockchain test execution was not configured to store preimages.
This changes makes it so that the block test executor takes a callback, just like the state test executor already does. This callback can be used to examine the post-execution state, e.g. to aid debugging of test failures.
* cmd, les, tests: remove light client code
This commit removes the light client (LES) code.
Since the merge the light client has been broken and
it is hard to maintain it alongside the normal client.
We decided it would be best to remove it for now and
maybe rework and reintroduce it in the future.
* cmd, eth: remove some more mentions of light mode
* cmd: re-add flags and mark as deprecated
* cmd: warn the user about deprecated flags
* eth: better error message
Adds a subcommand: `geth snapshot export-preimages`, to export preimages of every hash found during a snapshot enumeration: that is, it exports _only the active state_, and not _all_ preimages that have been used but are no longer part of the state.
This tool is needed for the verkle transition, in order to distribute the preimages needed for the conversion. Since only the 'active' preimages are exported, the output is shrunk from ~70GB to ~4GB.
The order of the output is the order used by the snapshot enumeration, which avoids database thrashing. However, it also means that storage-slot preimages are not deduplicated.
geth --dev can be used with an existing data directory and genesis block. Since
dev mode only works with PoS, we need to verify that the merge has happened.

It turns out that encoding json.RawMessage is slow because
package json basically parses the message again to ensure it is valid.
We can avoid the slowdown by encoding the entire RPC notification once,
which yields a 30% speedup.

This PR moves our fuzzers from tests/fuzzers into whatever their respective 'native' package is.
The historical reason why they were placed in an external location, is that when they were based on go-fuzz, they could not be "hidden" via the _test.go prefix. So in order to shove them away from the go-ethereum "production code", they were put aside.
But now we've rewritten them to be based on golang testing, and thus can be brought back. I've left (in tests/) the ones that are not production (bls128381), require non-standard imports (secp requires btcec, bn256 requires gnark/google/cloudflare deps).
This PR also adds a fuzzer for precompiled contracts, because why not.
This PR utilizes a newly rewritten replacement for go-118-fuzz-build, namely gofuzz-shim, which utilises the inputs from the fuzzing engine better.
This change allows the creation of a genesis block for verkle testnets. This makes for a chunk of code that is easier to review and still touches many discussion points.
Currently, geth's will return `[]` for any `len(topics) > 4` log filter. The EVM only supports up to four logs, via LOG4 opcode, so larger criterias fail. This change makes the filter query exit early in those cases.
cockroachdb/pebble@422dce9 added Errorf to the Logger interface, this change makes it possible to compile geth with that version of pebble by adding the corresponding method to panicLogger.
* cmd/geth: more testcases for logging
This adds more edgecases around logging, particularly around handling of different types of nil-values

Also adds tests with 'reserved' values which breaks json/logfmt formats. The json output is checked in,
but not actively used by any testcase at the moment.

Currently, one can use the "withLogs" parameter to include logs in the
callTracer results, which allows the user to see at which trace level
was each log emitted.
This commit adds a position field to the logs which determine
the exact ordering of a call's logs and its subcalls. This would
be useful e.g. for explorers wishing to display the flow of execution.

This change improves GenerateChain to support internal chain history access (ChainReader)
for the consensus engine and EVM.
GenerateChain takes a `parent` block and the number of blocks to create. With my changes,
the consensus engine and EVM can now access blocks from `parent` up to the block currently
being generated. This is required to make the BLOCKHASH instruction work, and also needed
to create real clique chains. Clique uses chain history to figure out if the current signer is in-turn,
for example.
I've also added some more accessors to BlockGen. These are helpful when creating transactions:
- g.Signer returns a signer instance for the current block
- g.Difficulty returns the current block difficulty
- g.Gas returns the remaining gas amount
Another fix in this commit concerns the receipts returned by GenerateChain. The receipts now
have properly derived fields (BlockHash, etc.) and should generally match what would be
returned by the RPC API.
This adds warning logs when the read does not match the expected count.
We can also remove the size limit since the function documentation explicitly states
that callers should limit the count.

This PR is a bit in preparation for the slog work in #28187 .
Our current test re logging mostly test the internals, but we have no real end-to-end test of the logging output. This PR introduces a simple reexec-based log tester. This also relies upon a special mode in geth, which can be made to eject a set of predefined log messages (only available if the build-tag `integrationtests` is used
e.g. go run --tags=integrationtests ./cmd/geth --log.format terminal logtest
While working on this, I also noticed a quirk in the setup: when geth was configured to use a file output, then two separate handlers were used (one handler for the file, one handler for the console). Using two separate handlers means that two formatters are used, thus the formatting of any/all records happened twice. This PR changes the mechanism to use two separate io.Writers instead, which is both more optimal and fixes a bug which occurs due to a global statefulness in the formatter.
The String() version of BlockNumberOrHash uses decimal for all block numbers, including negative ones used to indicate labels. Switch to using BlockNumber.String() which encodes it correctly for use in the JSON-RPC API.
This PR removes panics from stacktrie (mostly), and makes the Update return errors instead. While adding tests for this, I also found that one case of possible corruption was not caught, which is now fixed.
This change closes https://github.com/ethereum/go-ethereum/issues/27730 . By using an iterator instead of a slice of transactions, we can better handle the case when an individual transaction (within an otherwise well-formed RLP-list) cannot be decoded.
Fixes a bug where the ethstats omits to report full block contents. This bug was a side-effect of https://github.com/ethereum/go-ethereum/pull/26777, where `CurrentBlock` was changed to return a header instead of a block, leading to a failed type assertion.
A goroutine is used to manage the lifetime of subscriptions managed by
resubscriptions. When the subscription ends with no error, the resub
goroutine ends as well. However, the resub goroutine needs to live
long enough to read from the unsub channel. Otheriwse, an Unsubscribe
call deadlocks when writing to the unsub channel.
This is fixed by adding a buffer to the unsub channel.
* api/bind: Add CallOpts.BlockHash to allow calling contracts at a specific block hash.

This change enhances the stacktrie constructor by introducing an option struct. It also simplifies the `Hash` and `Commit` operations, getting rid of the special handling round root node.
This changes fixes a bug in the fetcher, where the timeout for how long to remember underpriced transaction was erroneously compared, and the timeout never hit.

This change fixes#28355, where eth_getProof failed to return the correct codehash under certain conditions. This PR changes the logic to unconditionally look up the codehash, and also adds some more tests.
During snap-sync, we request ranges of values: either a range of accounts or a range of storage values. For any large trie, e.g. the main account trie or a large storage trie, we cannot fetch everything at once.
Short version; we split it up and request in multiple stages. To do so, we use an origin field, to say "Give me all storage key/values where key > 0x20000000000000000". When the server fulfils this, the server provides the first key after origin, let's say 0x2e030000000000000 -- never providing the exact origin. However, the client-side needs to be able to verify that the 0x2e03.. indeed is the first one after 0x2000.., and therefore the attached proof concerns the origin, not the first key.
So, short-short version: the left-hand side of the proof relates to the origin, and is free-standing from the first leaf.
On the other hand, (pun intended), the right-hand side, there's no such 'gap' between "along what path does the proof walk" and the last provided leaf. The proof must prove the last element (unless there are no elements).
Therefore, we can simplify the semantics for trie.VerifyRangeProof by removing an argument. This doesn't make much difference in practice, but makes it so that we can remove some tests. The reason I am raising this is that the upcoming stacktrie-based verifier does not support such fancy features as standalone right-hand borders.

* build: move more build metadata into checksum file
* build: move gobootsrc to checksums
This change addresses an issue in snap sync, specifically when the entire sync process can be halted due to an encountered empty storage range.
Currently, on the snap sync client side, the response to an empty (partial) storage range is discarded as a non-delivery. However, this response can be a valid response, when the particular range requested does not contain any slots.
For instance, consider a large contract where the entire key space is divided into 16 chunks, and there are no available slots in the last chunk [0xf] -> [end]. When the node receives a request for this particular range, the response includes:
The proof with origin [0xf]
A nil storage slot set
If we simply discard this response, the finalization of the last range will be skipped, halting the entire sync process indefinitely. The test case TestSyncWithUnevenStorage can reproduce the scenario described above.
In addition, this change also defines the common variables MaxAddress and MaxHash.

This change
- Removes the owner-notion from a stacktrie; the owner is only ever needed for comitting to the database, but the commit-function, the `writeFn` is provided by the caller, so the caller can just set the owner into the `writeFn` instead of having it passed through the stacktrie.
- Removes the `encoding.BinaryMarshaler`/`encoding.BinaryUnmarshaler` interface from stacktrie. We're not using it, and it is doubtful whether anyone downstream is either.

When MatcherSession encounters an error, it attempts to close the session.
Closing waits for all goroutines to finish, including the 'distributor'. However, the
distributor will not exit until all requests have returned.
This patch fixes the issue by delivering the (empty) result to the distributor
before calling Close().
This PR makes the tool use the --bootnodes list as the input to devp2p crawl.
The flag will take effect if the input/output.json file is missing or empty.
* cmd/evm: improve flags handling
This fixes some issues with flags in cmd/evm. The supported flags did not
actually show up in help output because they weren't categorized. I'm also
adding the VM-related flags to the run command here so they can be given
after the subcommand name. So it can be run like this now:
./evm run --code 6001 --debug
* cmd/evm: enable all forks by default in run command
The default genesis was just empty with no forks at all, which is annoying because
contracts will be relying on opcodes introduced in a fork. So this changes the default to
have all forks enabled.
* core/asm: fix some issues in the assembler
This fixes minor bugs in the old assembler:
- It is now possible to have comments on the same line as an instruction.
- Errors for invalid numbers in the jump instruction are reported better
- Line numbers in errors were off by one
* rlp/rlpgen: remove build tag
This tag was supposed to prevent unstable output when types reference each other. Imagine
there are two struct types A and B, where a reference to type B is in A. If I run rlpgen
on type B first, and then on type A, the generator will see the B.EncodeRLP method and
call it. However, if I run rlpgen on type A first, it will inline the encoding of B.
The solution I chose for the initial release of rlpgen was to just ignore methods
generated by rlpgen using a build tag. But there is a problem with this: if any code in
the package calls EncodeRLP explicitly, the package can't be loaded without errors anymore
in rlpgen, because the loader ignores it. Would be nice if there was a way to just make it
ignore invalid functions during type checking (they're not necessary for rlpgen), but
golang.org/x/tools/go/packages does not provide a way of ignoring them.
Luckily, the types we use rlpgen with do not reference each other right now, so we can
just remove the build tags for now.
This adds block and receipt fields for EIP-4844.

This change includes a lot of things, listed below.
### Split up interfaces, write vs read
The interfaces have been split up into one write-interface and one read-interface, with `Snapshot` being the gateway from write to read. This simplifies the semantics _a lot_.
Example of splitting up an interface into one readonly 'snapshot' part, and one updatable writeonly part:
```golang
type MeterSnapshot interface {
Count() int64
Rate1() float64
Rate5() float64
Rate15() float64
RateMean() float64
}
// Meters count events to produce exponentially-weighted moving average rates
// at one-, five-, and fifteen-minutes and a mean rate.
type Meter interface {
Mark(int64)
Snapshot() MeterSnapshot
Stop()
}
```
### A note about concurrency
This PR makes the concurrency model clearer. We have actual meters and snapshot of meters. The `meter` is the thing which can be accessed from the registry, and updates can be made to it.
- For all `meters`, (`Gauge`, `Timer` etc), it is assumed that they are accessed by different threads, making updates. Therefore, all `meters` update-methods (`Inc`, `Add`, `Update`, `Clear` etc) need to be concurrency-safe.
- All `meters` have a `Snapshot()` method. This method is _usually_ called from one thread, a backend-exporter. But it's fully possible to have several exporters simultaneously: therefore this method should also be concurrency-safe.
TLDR: `meter`s are accessible via registry, all their methods must be concurrency-safe.
For all `Snapshot`s, it is assumed that an individual exporter-thread has obtained a `meter` from the registry, and called the `Snapshot` method to obtain a readonly snapshot. This snapshot is _not_ guaranteed to be concurrency-safe. There's no need for a snapshot to be concurrency-safe, since exporters should not share snapshots.
Note, though: that by happenstance a lot of the snapshots _are_ concurrency-safe, being unmutable minimal representations of a value. Only the more complex ones are _not_ threadsafe, those that lazily calculate things like `Variance()`, `Mean()`.
Example of how a background exporter typically works, obtaining the snapshot and sequentially accessing the non-threadsafe methods in it:
```golang
ms := metric.Snapshot()
...
fields := map[string]interface{}{
"count": ms.Count(),
"max": ms.Max(),
"mean": ms.Mean(),
"min": ms.Min(),
"stddev": ms.StdDev(),
"variance": ms.Variance(),
```
TLDR: `snapshots` are not guaranteed to be concurrency-safe (but often are).
### Sample changes
I also changed the `Sample` type: previously, it iterated the samples fully every time `Mean()`,`Sum()`, `Min()` or `Max()` was invoked. Since we now have readonly base data, we can just iterate it once, in the constructor, and set all four values at once.
The same thing has been done for runtimehistogram.
### ResettingTimer API
Back when ResettingTImer was implemented, as part of https://github.com/ethereum/go-ethereum/pull/15910, Anton implemented a `Percentiles` on the new type. However, the method did not conform to the other existing types which also had a `Percentiles`.
1. The existing ones, on input, took `0.5` to mean `50%`. Anton used `50` to mean `50%`.
2. The existing ones returned `float64` outputs, thus interpolating between values. A value-set of `0, 10`, at `50%` would return `5`, whereas Anton's would return either `0` or `10`.
This PR removes the 'new' version, and uses only the 'legacy' percentiles, also for the ResettingTimer type.
The resetting timer snapshot was also defined so that it would expose the internal values. This has been removed, and getters for `Max, Min, Mean` have been added instead.
### Unexport types
A lot of types were exported, but do not need to be. This PR unexports quite a lot of them.
This updates minisign to the latest version. One new thing is that minisign (not go-minisign) has started to prehash the file, and in order to make geth pass the version-check, we need to sign the file in legacy-mode.
On ACD 163, it was agreed to bump the target and max blob values from `2/4` to `3/6` for future devnets until we could decide on final mainnet number. This change contains said update, making master pass all the hive tests. The final decision for mainnet cancun is still to be made.

This changes implements faster post-selfdestruct iteration of storage slots for deletion, by using snapshot-storage+stacktrie to recover the trienodes to be deleted. This mechanism is only implemented for path-based schema.
For hash-based schema, the entire post-selfdestruct storage iteration is skipped, with this change, since hash-based does not actually perform deletion anyway.

This PR makes EIP-4788 work in the engine API and miner. It also fixes some bugs related to
EIP-4844 block processing and mining. Changes in detail:
- Header.BeaconRoot has been renamed to ParentBeaconRoot.
- The engine API now implements forkchoiceUpdatedV3
- newPayloadV3 method has been updated with the parentBeaconBlockRoot parameter
- beacon root is now applied to new blocks in miner
- For EIP-4844, block creation now updates the blobGasUsed field of the header
Just some minor optimizations I figured out a while ago. By using ReadBytes instead of
Bytes on the rlp stream, we can save the allocation of a temporary buffer for the typed tx
payload.
If kind == rlp.Byte, the size reported by Stream.Kind will be zero, but we need a buffer
of size 1 for ReadBytes. Since typed txs always have to be longer than 1 byte, we can just
return an error for kind == rlp.Byte.
There is a also a small change for Log: since the first three fields of Log are the ones that
should appear in the canon encoding, we can simply ignore the remaining fields via
struct tag. Doing this removes an indirection through the rlpLog type.

The PR #26274 broke the evm statetest command a bit, in that it stopped spitting out the stateroot following a non-successful statetest-execution.
This PR changes it back, so the stateroot is unconditionally output on stderr, and makes it so fuzzing works again.
This change implements "EIP 4788 : Beacon block root in the EVM". It implements version-2 of EPI-4788, main difference being that the contract is an actual contract rather than a precompile, as in #27289.
Currently, we trigger the logic to (un)index transactions when the node receives a new
block. However, in some cases the node may not receive new blocks (eg, when the Geth node
is configured without peer discovery, or when it acts as an RPC node for historical-only
data).
In these situations, the Geth node user may not have previously configured txlookuplimit
(i.e. the default of around one year), but later realizes they need to index all
historical blocks. However, adding txlookuplimit=0 and restarting geth has no effect. This
change makes it check for required indexing work once, on startup, to fix the issue.

Optimizations:
- Previously, if a transaction was reverting, EstimateGas would exhibit worst-case behavior and binary search up to the max gas limit (~40 state-clone + tx executions). This change allows EstimateGas to return after only a single unconstrained execution in this scenario.
- Uses the gas used from the unconstrained execution to bias the remaining binary search towards the likely solution in a simple way that doesn't impact the worst case. For a typical contract-invoking transaction, this reduces the median number of state-clone+executions from 25 to 18 (28% reduction).
Cleanup:
- added & improved function + code comments
- correct the EstimateGas documentation to clarify the gas limit determination is at latest block, not pending, if the blockNr is unspecified.
ReadSkeletonHeader can return nil if the header is missing, so we should
not access fields on it. Note that calling .Hash() on a nil header is fine, so there
is no need to actually check for nil.

This changes the forkID calculation to ignore time-based forks that occurred before the
genesis block. It's supposed to be done this way because the spec says:
> If a chain is configured to start with a non-Frontier ruleset already in its genesis, that is NOT considered a fork.
This raises the JSON-RPC batch request limits significantly for the engine API endpoint.
The limits are now also hard-coded, so users won't get them wrong. I have chosen these limits:
maximum batch items: 2000
maximum batch response size: 250MB
While it would also be possible to disable batch limits completely for the engine API,
I think having some limits is a good safety net against misbehaving CLs. Since this
isn't configurable, we really want to ensure this limit will never become an issue in the
CL/EL communication, so I set them quite high.

This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way
of keeping the blob sidecar within types.Transaction. It's better this way because most
code in go-ethereum does not care about blob transactions, and probably never will. This
will start mattering especially on the client side of RPC, where all APIs are based on
types.Transaction. Users need to be able to use the same signing flows they already
have.
However, since blobs are only allowed in some places but not others, we will now need to
add checks to avoid creating invalid blocks. I'm still trying to figure out the best place
to do some of these. The way I have it currently is as follows:
- In block validation (import), txs are verified not to have a blob sidecar.
- In miner, we strip off the sidecar when committing the transaction into the block.
- In TxPool validation, txs must have a sidecar to be added into the blobpool.
- Note there is a special case here: when transactions are re-added because of a chain
reorg, we cannot use the transactions gathered from the old chain blocks as-is,
because they will be missing their blobs. This was previously handled by storing the
blobs into the 'blobpool limbo'. The code has now changed to store the full
transaction in the limbo instead, but it might be confusing for code readers why we're
not simply adding the types.Transaction we already have.
Code changes summary:
- txpool.Transaction removed and all uses replaced by types.Transaction again
- blobpool now stores types.Transaction instead of defining its own blobTx format for storage
- the blobpool limbo now stores types.Transaction instead of storing only the blobs
- checks to validate the presence/absence of the blob sidecar added in certain critical places
The Go authors updated golang/x/ext to change the function signature of the slices sort method.
It's an entire shitshow now because x/ext is not tagged, so everyone's codebase just
picked a new version that some other dep depends on, causing our code to fail building.
This PR updates the dep on our code too and does all the refactorings to follow upstream...
This should fix#27726. With enough load, it might happen that the SetPongHandler
callback gets invoked before the call to SetReadDeadline is made in pingLoop. When
this occurs, the socket will end up with a 30s read deadline even though it got the pong,
which will lead to a timeout.
The fix here is processing the pong on pingLoop, synchronizing with the code that
sends the ping.
Block takes a number and a hash. The spec is unclear on what should happen in this case, leaving it an implemenation detail. With this change, we return an error in case both number and hash are passed in.
This change removes a chainconfig parameter passed into rawdb.ReadLogs, which is not used nor needed.
It also modifies the filter loop slightly, avoiding a labeled break and instead using a method.
This change does not modify any behaviour.
Context: The UpdateContractCode method was introduced for the state storage commitment
schemes that include the whole code for their commitment computation. It must therefore be called
before the root hash is computed at the end of IntermediateRoot.
This should have no impact on the MPT since, in this context, the method is a no-op.
This adds support for the "yParity" field in transaction objects returned by RPC
APIs. We somehow forgot to add this field even though it has been in the spec for
a long time.
This change rearranges the accessor methods in block.go and fixes some minor issues with
the copy-on-write logic of block data. Fixed issues:
- Block.WithWithdrawals did not create a shallow copy of the block.
- Block.WithBody copied the header unnecessarily, and did not preserve withdrawals.
However, the bugs did not affect any code in go-ethereum because blocks are *always*
created using NewBlockWithHeader().WithBody().WithWithdrawals()

This change adds the ability to perform reads from freezer without size limitation. This can be useful in cases where callers are certain that out-of-memory will not happen (e.g. reading only a few elements).
The previous API was designed to behave both optimally and secure while servicing a request from a peer, whereas this change should _not_ be used when an untrusted peer can influence the query size.
This simplifies the code that initializes the discovery a bit, and
adds new flags for enabling/disabling discv4 and discv5 separately.

This change makes the StateDB track the state key value diff of a block transition.
We already tracked current account and storage values for the purpose of updating
the state snapshot. With this PR, we now also track the original (pre-transition) values
of accounts and storage slots.
Back before #27178 , we spun up a number of ethash verifiers to verify headers. So we also had tests to ensure that we were indeed able to abort verification even if we had multiple workers running.
With PR #27178, we removed the parallelism in verification, and these tests are now failing, since we now just sequentially fire away the results as fast as possible on one routine.
This change removes the (sometimes failing) tests

The clean trie cache is persisted periodically, therefore Geth can
quickly warmup the cache in next restart.
However it will reduce the robustness of system. The assumption is
held in Geth that if the parent trie node is present, then the entire
sub-trie associated with the parent are all prensent.
Imagine the scenario that Geth rewinds itself to a past block and
restart, but Geth finds the root node of "future state" in clean
cache then regard this state is present in disk, while is not in fact.
Another example is offline pruning tool. Whenever an offline pruning
is performed, the clean cache file has to be removed to aviod hitting
the root node of "deleted states" in clean cache.
All in all, compare with the minor performance gain, system robustness
is something we care more.

This is likely the culprit behind several data corruption issues, e.g. where data has been
written to the freezer, but the deletion from pebble does not go through due to process
crash.
The state availability is checked during the creation of a state reader.
- In hash-based database, if the specified root node does not exist on disk disk, then
the state reader won't be created and an error will be returned.
- In path-based database, if the specified state layer is not available, then the
state reader won't be created and an error will be returned.
This change also contains a stricter semantics regarding the `Commit` operation: once it has been performed, the trie is no longer usable, and certain operations will return an error.
This removes the feature where top nodes of the proof can be elided.
It was intended to be used by the LES server, to save bandwidth
when the client had already fetched parts of the state and only needed
some extra nodes to complete the proof. Alas, it never got implemented
in the client.

This PR adds server-side limits for JSON-RPC batch requests. Before this change, batches
were limited only by processing time. The server would pick calls from the batch and
answer them until the response timeout occurred, then stop processing the remaining batch
items.
Here, we are adding two additional limits which can be configured:
- the 'item limit': batches can have at most N items
- the 'response size limit': batches can contain at most X response bytes
These limits are optional in package rpc. In Geth, we set a default limit of 1000 items
and 25MB response size.
When a batch goes over the limit, an error response is returned to the client. However,
doing this correctly isn't always possible. In JSON-RPC, only method calls with a valid
`id` can be responded to. Since batches may also contain non-call messages or
notifications, the best effort thing we can do to report an error with the batch itself is
reporting the limit violation as an error for the first method call in the batch. If a batch is
too large, but contains only notifications and responses, the error will be reported with
a null `id`.
The RPC client was also changed so it can deal with errors resulting from too large
batches. An older client connected to the server code in this PR could get stuck
until the request timeout occurred when the batch is too large. **Upgrading to a version
of the RPC client containing this change is strongly recommended to avoid timeout issues.**
For some weird reason, when writing the original client implementation, @fjl worked off of
the assumption that responses could be distributed across batches arbitrarily. So for a
batch request containing requests `[A B C]`, the server could respond with `[A B C]` but
also with `[A B] [C]` or even `[A] [B] [C]` and it wouldn't make a difference to the
client.
So in the implementation of BatchCallContext, the client waited for all requests in the
batch individually. If the server didn't respond to some of the requests in the batch, the
client would eventually just time out (if a context was used).
With the addition of batch limits into the server, we anticipate that people will hit this
kind of error way more often. To handle this properly, the client now waits for a single
response batch and expects it to contain all responses to the requests.

ethclient accepts certain negative block number values as specifiers for the "pending",

This wasn't really a problem, but other values accepted by ethclient did match the
definitions in package rpc, and it's weird to have this one special case where they don't.
To fix it, we decided to change the values of the constants rather than changing ethclient.
The constant values are not otherwise significant. This is a breaking API change, but we

sends a TALKREQ back. With TalkRequestToID, node B does not need the ENR of A to
send its request.

This PR unifies the error handling in miner.
Whenever an error occur while applying a transaction, the transaction should be regarded as invalid and all following transactions from the same sender not executable because of the nonce restriction. The only exception is the `nonceTooLow` error which is handled separately.
Prior to this change, it was possible that transactions are erroneously deemed as 'future' although they are in fact 'pending', causing them to be dropped due to 'future' not being allowed to replace 'pending'.
This change fixes that, by doing a more in-depth inspection of the queue.

This includes a semantic change to the `callTracer` as well as `flatCallTracer`.
The value of field `gas` in the **first** call frame will change as follows:
- It previously contained gas available after initial deductions (i.e. tx costs)
- It will now contain the full tx gasLimit value

Currently, most of transaction validation while holding the txpool mutex: one exception being an early-on signature check.
This PR changes that, so that we do all non-stateful checks before we entering the mutex area. This means they can be performed in parallel, and to enable that, certain fields have been made atomic bools and uint64.
This change enables log rotation, which can be activated using the flag --log.rotate. Additional parameters that can be given are:
- log.maxsize to set maximum size before files are rotated,
- log.maxbackups to set how many files are retailed,
- log.maxage to configure max age of rotated files,
- log.compress whether to compress rotated files
The way to configure location of the logfile(s) is left unchanged, via the `log.logfile` parameter.

This change switches to use the smaller influxdata/influxdb1-client package instead of depending on the whole infuxdb package. The new smaller client is very similar to the influxdb-v2 client, which made it possible to refactor the two reporters to reuse code a lot more.
This PR adds counter metrics for the CPU system and the Geth process.
Currently the only metrics available for these items are gauges. Gauges are
fine when the consumer scrapes metrics data at the same interval as Geth
produces new values (every 3 seconds), but it is likely that most consumers
will not scrape that often. Intervals of 10, 15, or maybe even 30 seconds
are probably more common.
So the problem is, how does the consumer estimate what the CPU was doing in
between scrapes. With a counter, it's easy ... you just subtract two
successive values and divide by the time to get a nice, accurate average.
But with a gauge, you can't do that. A gauge reading is an instantaneous
picture of what was happening at that moment, but it gives you no idea
about what was going on between scrapes. Taking an average of values is
meaningless.
This changes the Trie interface to add the plain account address as a
parameter to all storage-related methods.
After the introduction of the TryAccount* functions, TryGet, TryUpdate and
TryDelete are now only meant to read an account's storage. In their current
form, they assume that an account storage is stored in a separate trie, and
that the hashing of the slot is independent of its account's address.
The proposed structure for a stateless storage breaks these two
assumptions: the hashing of a slot key requires the address and all slots
and accounts are stored in a single trie.
This PR therefore adds an address parameter to the interface. It is ignored
in the MPT version, so this change has no functional impact, however it
will reduce the diff size when merging verkle trees.
With #25287 we made it so that preimages were not recorded by default. This had the side effect that the evm command is no longer able to dump state since it does a preimage lookup to determine the address represented by a key.
This change enables the recording of preimages when the dump command is given.
The meter for "for measuring the effective amount of data read" within the freezertable was never updated. This change remedies that.

Makes clear the distinction between Finalize and FinalizedAndAssemble:
- In Finalize function, a series of state operations are applied according to consensus rules. The statedb is mutated and the root hash can be checked and compared afterwards.
This function should be used in block processing(receive afrom network and apply it locally) but not block generation.
- In FinalizeAndAssemble function, after applying state mutations, the block is also to be assembled with the latest
state root computed, updating the header.
This function should be used in block generation only.
This adds two new rules to the transaction pool:
- A future transaction can not evict a pending transaction.
- A transaction can not overspend available funds of a sender.

Here, the core.Message interface turns into a plain struct and
types.Message gets removed.
This is a breaking change to packages core and core/types. While we do
not promise API stability for package core, we do for core/types. An
exception can be made for types.Message, since it doesn't have any
purpose apart from invoking the state transition in package core.
types.Message was also marked deprecated by the same commit it
got added in, 4dca5d4db7 (November 2016).
The core.Message interface was added in December 2014, in commit
db494170dc, for the purpose of 'testing' state transitions. It's the
same change that made transaction struct fields private. Before that,
the state transition used *types.Transaction directly.
Over time, multiple implementations of the interface accrued across
different packages, since constructing a Message is required whenever
one wants to invoke the state transition. These implementations all
looked very similar, a struct with private fields exposing the fields
as accessor methods.
By changing Message into a struct with public fields we can remove all
these useless interface implementations. It will also hopefully
simplify future changes to the type with less updates to apply across
all of go-ethereum when a field is added to Message.

This PR mitigates an issue with Ledger's on-device RLP deserialization, see
https://github.com/LedgerHQ/app-ethereum/issues/409
Ledger's RLP deserialization code does not validate the length of the RLP list received,
and it may prematurely enter the signing flow when a APDU chunk boundary falls immediately
before the EIP-155 chain_id when deserializing a transaction. Since the chain_id is
uninitialized, it is 0 during this signing flow. This may cause the user to accidentally
sign the transaction with chain_id = 0. That signature would be returned from the device 1
packet earlier than expected by the communication loop. The device blocks the
second-to-last packet waiting for the signer flow, and then errors on the successive
packet (which contains the chain_id, zeroed r, and zeroed s)
Since the signature's early arrival causes successive errors during the communication
process, geth does not parse the improper signature produced by the device, and therefore
no improperly-signed transaction can be created. User funds are not at risk.
We mitigate by selecting the highest chunk size that leaves at least 4 bytes in the
final chunk.

This change fixes a flaw where, in certain scenarios, the block sealer did not accurately reset the remaining gas after failing to include an invalid transaction. Fixes#26791
This PR changes metrics collection to actually measure the time interval between collections, rather
than assume 3 seconds. I did some ad hoc profiling, and on slower hardware (eg, my Raspberry Pi 4)
I routinely saw intervals between 3.3 - 3.5 seconds, with some being as high as 4.5 seconds. This
will generally cause the CPU gauge readings to be too high, and in some cases can cause impossibly
large values for the CPU load metrics (eg. greater than 400 for a 4 core CPU).

Adds support for a native call tracer with the Parity format, which outputs call frames
in a flat array. This tracer accepts the following options:
- `convertParityErrors: true` will convert error messages to match those of Parity
- `includePrecompiles: true` will report all calls to precompiles. The default
matches Parity's behavior where CALL and STATICCALLs to precompiles are excluded
Incompatibilities with Parity include:
- Parity removes the result object in case of failure. This behavior is maintained
with the exception of reverts. Revert output usually contains useful information,
i.e. Solidity revert reason.
- The `gasUsed` field accounts for intrinsic gas (e.g. 21000 for simple transfers)
and refunds unlike Parity
- Block rewards are not reported

This PR is a (superior) alternative to https://github.com/ethereum/go-ethereum/pull/26708, it handles deprecation, primarily two specific cases.
`rand.Seed` is typically used in two ways
- `rand.Seed(time.Now().UnixNano())` -- we seed it, just to be sure to get some random, and not always get the same thing on every run. This is not needed, with global seeding, so those are just removed.
- `rand.Seed(1)` this is typically done to ensure we have a stable test. If we rely on this, we need to fix up the tests to use a deterministic prng-source. A few occurrences like this has been replaced with a proper custom source.
`rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.
This PR relaxes the block body ingress handling a bit: if block body withdrawals are missing (but expected to be empty), the body withdrawals are set to 'empty list' before being passed to upper layers.
This fixes an issue where a block passed from EthereumJS to geth was deemed invalid.
Our discovery crawler spits out a huge amount of logs, most of which is pretty non-interesting. This change moves the very verbose output to Debug, and adds a 8-second status log message giving the general idea about what's going on.
Logs stored on disk have minimal information. Contextual information such as block
number, index of log in block, index of transaction in block are filled in upon request.
We can fill in all these fields only having the block header and list of receipts.
But determining the transaction hash of a log requires the block body.
The goal of this PR is postponing this retrieval until we are sure we the transaction hash.
It happens often that the header bloom filter signals there might be matches in a block,
but after actually checking them reveals the logs do not match. We want to avoid fetching
the body in this case.
Note that this changes the semantics of Backend.GetLogs. Downstream callers of
GetLogs now assume log context fields have not been derived, and need to call
DeriveFields on the logs if necessary.
This is a breaking change in the tracing hooks API as well as semantics of the callTracer:
- CaptureEnter hook provided a nil value argument in case of DELEGATECALL. However to stay consistent with how delegate calls behave in EVM this hook is changed to pass in the value of the parent call.
- callTracer will return parent call's value for DELEGATECALL frames.

This change introduces a breaking change to miner.etherbase is configured.
Previously, users did not need to explicitly set the etherbase address via flag, since 'first' local account was used as etherbase automatically. This change removes the "default first account" feature.
In Proof-of-stake world, the fee recipient address is provided by CL, and not configured in Geth any more - meaning that miner.etherbase is mostly for legacy networks(pow, clique networks etc).

This PR does a few things.
It fixes a shutdown-order flaw in the chainfreezer. Previously, the chain-freezer would shutdown the freezer backend first, and then signal for the loop to exit. This can lead to a scenario where the freezer tries to fsync closed files, which is an error-conditon that could lead to exit via log.Crit.
It also makes the printout more detailed when truncating 'dangling' items, by showing the exact number instead of approximate MB.
This PR also adds calls to fsync files before closing them, and also makes the `db inspect` command slightly more robust.

This PR fixes an issue which might result in data lost in freezer.
Whenever mutation happens in freezer, all data will be written into head data file
and it will be rotated with a new one in case the size of file reaches the threshold.
Theoretically, the rotated old data file should be fsync'd to prevent data loss.
In freezer.Sync function, we only fsync: (1) index file (2) meta file and (3) head
data file. So this PR forcibly fsync the head data file if mutation happens in the
boundary of data file.
In legacy (pre-merge) sync mode, headers were contiguously downloaded from the network and when no more headers were available, we checked every few seconds whether there are 64 new blocks to move the pivot.
In beacon (post-merge) sync mode, we don't need to check for new skeleton headers non stop, since those re delivered one by one by the engine API. The missing code snippet from the header fetcher was to actually look at the latest head and move the pivot if it was more than 2*64-8 away. This PR adds the missing movement logic.
This makes non-JS tracers execute all block txs on a single goroutine.
In the previous implementation, we used to prepare every tx pre-state
on one goroutine, and then run the transactions again with tracing enabled.
Native tracers are usually faster, so it is faster overall to use their output as
the pre-state for tracing the next transaction.

The new name captures the meaning of this field better.
Alarm is a timer utility that simplifies code where a timer needs to be rescheduled over
and over. Doing this can be tricky with time.Timer or time.AfterFunc because the channel
requires draining in some cases.
Alarm is optimized for use cases where items are tracked in a heap according to their expiry
time, and a goroutine with a for/select loop wants to be woken up whenever the next item expires.
In this application, the timer needs to be rescheduled when an item is added or removed
from the heap. Using a timer naively, these updates will always require synchronization
with the global runtime timer datastructure to update the timer using Reset. Alarm avoids
this by tracking the next expiry time and only modifies the timer if it would need to fire earlier
than already scheduled.
As an example use, I have converted p2p.dialScheduler to use Alarm instead of AfterFunc.
This changes moves the tracking of "deleted in this block" out from snap-only domain, so that it happens regardless of whether the execution is snapshot-backed or trie-backed.
This changes the StorageTrie method to return an error when the trie

This change adds checks to the beacon consensus engine, making it more strict in validating the pre- and post-headers, and not relying on the caller to have already correctly sanitized the headers/blocks.
This PR implements resettable freezer by adding a ResettableFreezer wrapper.
The resettable freezer wraps the original freezer in a way that makes it possible to ensure atomic resets. Implementation wise, it relies on the os.Rename and os.RemoveAll to atomically delete the original freezer data and re-create a new one from scratch.
This PR fixes an error in trie commit. If the trie.root is nil, it can be two possible scenarios:
- The trie was empty, and no change happens
- The trie was non-empty and all nodes are dropped
For the latter one, we should collect the deletions and apply them into database(e.g. in PBSS).
This ensures that RPC method handlers will react to a timeout or
cancelled request soon after the event occurs.

This PR adds a new type event.FeedOf[T], which is like event.Feed but parameterized
over the channel element type. Performance is unchanged, and it still uses reflect. But
unlike Feed, the generic version doesn't need to type-check interface{} arguments.
All panic cases are gone from the API.
While investigating another issue, I found that all callers of collectLogs have the
complete block available. rawdb.ReadReceipts loads the block from the database,
so it is better to use ReadRawReceipts here, and derive the receipt information using
the block which is already in memory.
This PR makes it possible to modify the flush interval time via RPC. On one extreme, `0s`, it would act as an archive node. If set to `1h`, means that after one hour of effective block processing time, the trie would be flushed. If one block takes 200ms, this means that a flush would occur every `5*3600=18000` blocks -- however, if the memory size of the cached states grows too large, it will flush sooner.
Essentially, this makes it possible to configure the node to be more or less "archive:ish", and without restarting the node while reconfiguring it.
--syncTarget is a feature for development purpose in post-merge world. Previously
it's added into eth.Config. But it turns out that's a stupid idea.
- syncTarget is a block object, which is hard to be put in config file(large)
- syncTarget is just a dev feature, doesn't make too much sense to add it in config file
So I remove it from the eth config object. And it also fixes the #26328
This improves readability of function 'push'.
sort.Search(N, ...) will at most return N when no match, so ix should be compared
with N. The previous version would compare ix with N+1 in case an additional item
was appended. No bug resulted from this comparison, but it's not easy to understand
why.

The gcproc field tracks the amount of time spent processing blocks,
and is used to trigger a state flush to disk when a certain threshold is
reached. After the merge, single block insertion by CL is the most
common source of block processing time, but this time was not added
into gcproc.
Here we add special handling for sending an error response when the write timeout of the
HTTP server is just about to expire. This is surprisingly difficult to get right, since is
must be ensured that all output is fully flushed in time, which needs support from
multiple levels of the RPC handler stack:
The timeout response can't use chunked transfer-encoding because there is no way to write
the final terminating chunk. net/http writes it when the topmost handler returns, but the
timeout will already be over by the time that happens. We decided to disable chunked
encoding by setting content-length explicitly.
Gzip compression must also be disabled for timeout responses because we don't know the
true content-length before compressing all output, i.e. compression would reintroduce
chunked transfer-encoding.
The new flag allows configuring an explicit endpoint which is to be
announced in the DHT. This feature was originally developed for the
discv5 wormhole experiment (#25798), but it's useful in other contexts
as well.
This removes the 'time' field from logs, as well as from the tracer interface. This change makes the trace output deterministic. If a tracer needs the time they can measure it themselves. No need for evm to do this.

This changes the Pop method to assign the zero value before
reducing slice size. Doing so ensures the backing array does not
reference removed item values.
This PR drops the legacy receipt types, the freezer-migrate command and the startup check. The previous attempt #22852 at this failed because there were users who still had legacy receipts in their db, so it had to be reverted #23247. Since then we added a command to migrate legacy dbs #24028.
As of the last hardforks all users either must have done the migration, or used the --ignore-legacy-receipts flag which will stop working now.
This PR introduces a node scheme abstraction. The interface is only implemented by `hashScheme` at the moment, but will be extended by `pathScheme` very soon.
Apart from that, a few changes are also included which is worth mentioning:
- port the changes in the stacktrie, tracking the path prefix of nodes during commit
- use ethdb.Database for constructing trie.Database. This is not necessary right now, but it is required for path-based used to open reverse diff freezer
This PR should makes it easier to sign EIP-712 typed data via the accounts.Wallet API, by using the mimetype for typed data.

While investigating #22374, I noticed that the Sync operation of the

rpc: fix connection tracking in Server
When upgrading to mapset/v2 with generics, the set element type used in
rpc.Server had to be changed to *ServerCodec because ServerCodec is not
'comparable'. While the distinction is technically correct, we know all
possible ServerCodec types, and all of them are comparable. So just use
a map instead.
It seems there is no fully typed library implementation of an LRU cache.
So I wrote one. Method names are the same as github.com/hashicorp/golang-lru,
and the new type can be used as a drop-in replacement.
Two reasons to do this:
- It's much easier to understand what a cache is for when the types are right there.
- Performance: the new implementation is slightly faster and performs zero memory
allocations in Add when the cache is at capacity. Overall, memory usage of the cache
is much reduced because keys are values are no longer wrapped in interface.
This PR changes the pending tx subscription to return RPCTransaction types instead of normal Transaction objects. This will fix the inconsistencies with other tx returning API methods (i.e. getTransactionByHash), and also fill in the sender value for the tx.

This fixes a problem in the SizeConstrainedLRU. The SCLRU uses an underlying simple lru which is not thread safe.
During the Get operation, the recentness of the accessed item is updated, so it is not a pure read-operation. Therefore, the mutex we need is a full mutex, not RLock.
This PR changes the mutex to be a regular Mutex, instead of RWMutex, so a reviewer can at a glance see that all affected locations are fixed.
This changes how we read performance metrics from the Go runtime. Instead
of using runtime.ReadMemStats, we now rely on the API provided by package
runtime/metrics.
runtime/metrics provides more accurate information. For example, the new
interface has better reporting of memory use. In my testing, the reported
value of held memory more accurately reflects the usage reported by the OS.
The semantics of metrics system/memory/allocs and system/memory/frees have
changed to report amounts in bytes. ReadMemStats only reported the count of
allocations in number-of-objects. This is imprecise: 'tiny objects' are not
counted because the runtime allocates them in batches; and certain
improvements in allocation behavior, such as struct size optimizations,
will be less visible when the number of allocs doesn't change.
Changing allocation reports to be in bytes makes it appear in graphs that
lots more is being allocated. I don't think that's a problem because this
metric is primarily interesting for geth developers.
The metric system/memory/pauses has been changed to report statistical
values from the histogram provided by the runtime. Its name in influxdb has
changed from geth.system/memory/pauses.meter to
geth.system/memory/pauses.histogram.
We also have a new histogram metric, system/cpu/schedlatency, reporting the
Go scheduler latency.
This adds an option to direct log output to a file. This feature has been
requested a lot. It's sometimes useful to have this available when running
geth in an environment that doesn't easily allow redirecting the output.
Notably, there is no support for log rotation with this change. The --log.file option
opens the file once on startup and then keeps writing to the file handle.
This can become an issue when external log rotation tools are involved, so it's
best not to use them with this option for now.
When the interpreter is configured to use extra-eips, this change makes it so that all the opcodes are deep-copied, to prevent accidental modification of the 'base' jumptable.

Many of the other types have a function to convert the type to a big.Int,
but Address was missing this function.
It is useful to be able to turn an Address into a big.Int when doing
EVM-like computations natively in Go. Sometimes a Solidity address
type is casted to a uint256 and having a Big method on the Address
type makes this easy.
Instead of using a limit of three nodes per message, we can pack more nodes
into each message based on ENR size. In my testing, this halves the number
of sent NODES messages, because ENR size is usually < 300 bytes.
This also adds RLP helper functions that compute the encoded size of
[]byte and string.

In some cases, it is desirable to capture what is triggered by each trace, when using the `callTracer`. For example: call `USDT.transfer` will trigger a `Transfer(from, to, value)` event.

This PR introduces a new mechanism in chain tracer for preventing creating too many trace states.
The workflow of chain tracer can be divided into several parts:
- state creator generates trace state in a thread
- state tracer retrieves the trace state and applies the tracing on top in another thread
- state collector gathers all result from state tracer and stream to users
It's basically a producer-consumer model here, while if we imagine that the state producer generates states too fast, then it will lead to accumulate lots of unused states in memory. Even worse, in path-based state scheme it will only keep the latest 128 states in memory, and the newly generated state will invalidate the oldest one by marking it as stale.
The solution for fixing it is to limit the speed of state generation. If there are over 128 states un-consumed in memory, then the creation will be paused until the states are be consumed properly.
Backwards compatibility warning: The result will from now on omit empty fields instead
of including a zero value (e.g. no more `balance: '0x'`).
The prestateTracer will now take an option `diffMode: bool`. In this mode
the tracer will output the pre state and post data for the modified parts of state.
Read-only accesses will be completely omitted. Creations (be it account or slot)
will be signified by omission in the `pre` list and inclusion in `post`. Whereas
deletion (be it account or slot) will be signified by inclusion in `pre` and omission
in `post` list.

This PR makes it so that the snap server responds to trie heal requests when possible, even if the snapshot does not exist. The idea being that it might prolong the lifetime of a state root, so we don't have to pivot quite as often.
This PR makes it possible to set custom headers, in particular for two scenarios:
- geth attach
- geth commands which can use --remotedb, e..g geth db inspect
The ability to use custom headers is typically useful for connecting to cloud-apis, e.g. providing an infura- or alchemy key, or for that matter access-keys for environments behind cloudflare.

This PR reworks tx indexer a bit. Compared to the original version, one scenario is no longer handled - upgrading from legacy geth without indexer support.
The tx indexer was introduced in 2020 and have been present through hardforks, so it can be assumed that all Geth nodes have tx indexer already. So we can simplify the tx indexer logic a bit:
- If the tail flag is not present, it means node is just initialized may or may not with an ancient store attached. In this case all blocks are regarded as unindexed
- If the tail flag is present, it means blocks below tail are unindexed, blocks above tail are indexed
This change also address some weird cornercases that could make the indexer not work after a crash.
This fixes a bug where contract code would be overridden to empty code ("0x")

The call tracer and prestate tracer store data JSON-encoded in memory. In order to support alternative encodings (specifically RLP), it's better to keep data a native format during tracing. This PR does marshalling at the end, using gencodec.
OBS!
This PR changes the call tracer result slightly:
- Order of type and value fields are changed (should not matter).
- Output fields are completely omitted when they're empty (no more output: "0x"). Previously, this was only _sometimes_ omitted (e.g. when call ended in a non-revert error) and otherwise 0x when the output was actually empty.
Some tests define an 'expectException' error but the tests runner does not check for conditions where this test value is filled (error expected) but in which no error is returned by the test runner.
An example of this scenario is GeneralStateTests/stTransactionTest/HighGasPrice.json, which expects a 'TR_NoFunds' error, but the test runner does not return any error.

This PR cleans up the configurations for pruner and snapshotter by passing a config struct.
And also, this PR disables the snapshot background generation if the chain is opened in "read-only" mode. The read-only mode is necessary in some cases. For example, we have a list of commands to open the etheruem node in "read-only" mode, like export-chain. In these cases, the snapshot background generation is non expected and should be banned explicitly.
The abigen exclusion pattern, previously on the form "path:type", now supports wildcards. Examples "*:type" to exclude a named type in all files, or "/path/to/foo.sol:*" all types in foo.sol.
This changes the CI build to store the git commit and date into package
internal/version instead of package main. Doing this essentially merges our
two ways of tracking the go-ethereum version into a single place, achieving
two objectives:
- Bad block reports, which use version.Info(), will now have the git commit
information even when geth is built in an environment such as
launchpad.net where git access is unavailable.
- For geth builds created by `go build ./cmd/geth` (i.e. not using `go run
build/ci.go install`), git information stored by the go tool is now used
in the p2p node name as well as in `geth version` and `geth
version-check`.
Sometimes we get stuck on db compaction, and the CL re-issues the "same" command to us multiple times. Each request get stuck on the same place, in the middle of the handler.
This changes makes it so we do not reprocess the same payload, but instead detects it early.
core/blockchain: downgrade tx indexing and unindexing logs from info to debug
If a user has a finite tx lookup limit, they will see an "unindexing" info level log each time a block is imported. This information might help a user understand that they are removing the index each block and some txs may not be retrievable by hash, but overall it is generally more of a nuisance than a benefit. This change downgrades the log to a debug log.
This shortens the chain config summary in bad block reports,
and adds go-ethereum version information as well.

This changes the CI / release builds to use the latest Go version. It also
upgrades golangci-lint to a newer version compatible with Go 1.19.
In Go 1.19, godoc has gained official support for links and lists. The
syntax for code blocks in doc comments has changed and now requires a
leading tab character. gofmt adapts comments to the new syntax
automatically, so there are a lot of comment re-formatting changes in this
PR. We need to apply the new format in order to pass the CI lint stage with
Go 1.19.
With the linter upgrade, I have decided to disable 'gosec' - it produces
too many false-positive warnings. The 'deadcode' and 'varcheck' linters
have also been removed because golangci-lint warns about them being
unmaintained. 'unused' provides similar coverage and we already have it
enabled, so we don't lose much with this change.

The p2p msgrate tracker is a thing which tries to estimate some mean round-trip times. However, it did so in a very curious way: if a node had 200 peers, it would sort their 200 respective rtt estimates, and then it would pick item number 2 as the mean. So effectively taking third fastest and calling it mean. This probably works "ok" when the number of peers are low (there are other factors too, such as ttlScaling which takes some of the edge off this) -- however when the number of peers is high, it becomes very skewed.
This PR instead bases the 'mean' on the square root of the length of the list. Still pretty harsh, but a bit more lenient.
This PR includes minor updates to comments in trie/committer that reference insertion to the db, and adds an err != nil check for the return value of preimages.commit.
This PR simplifies the logic of chain tracer and also adds the unit tests.
The most important change has been made in this PR is the state management. Whenever a tracing state is acquired there is a corresponding release function be returned as well. It must be called once the state is used up, otherwise resource leaking can happen.
And also the logic of state management has been simplified a lot. Specifically, the state provider(eth backend, les backend) should ensure the state is available and referenced. State customers can use the state according to their own needs, or build other states based on the given state. But once the release function is called, there is no guarantee of the availability of the state.

The JSON-RPC spec requires the "version" field to be exactly "2.0",
so we should verify that. This change is not backwards-compatible with
sloppy client implementations, but I decided to go ahead with it anyway
because the failure will be caught via the returned error.
This adds a generic mechanism for 'dial options' in the RPC client,
and also implements a specific dial option for the JWT authentication
mechanism used by the engine API. Some real tests for the server-side
authentication handling are also added.

It's a trivial PR to hide the error log when the trie node is not found in the database. The idea for this change is for all TryXXX functions, the error is already returned and we don't need to fire a log explicitly.
Recently there are a few tickets #25613#25589 reporting that the trie nodes are missing because of debug.SetHead. The root cause is after resetting, the chain rewinds to a historical point and re-imports the blocks on top.
Since the node is already synced and started to accept transactions previously, these transactions are still kept in the txpool and verified by txpool with a live state. This live state is constructed based on the live trie database, which is changed fast by node referencing and de-referencing.
Unfortunately, when we construct a live state(like the state in txpool), we don't reference the state we have. The blockchain will garbage collect the intermediate version nodes in another thread which leads the broken live state.
The best solution for this is to forcibly obtain a reference for all live states we create and call release function once it's used up. But it might end up with more junks persisted into disk. Will try to find an elegant solution later in the following PR.
Some small fixes to get the existing debug methods to conform to the spec. Mainly dropping the encoding information from the method name as it should be deduced from the debug context and allowing the method to be invoked by either block number or block hash. It also adds the method debug_getTransaction which returns the raw tx bytes by tx hash. This is pretty much equivalent to the eth_getRawTransactionByHash method.

This avoids copying the input []byte while decoding trie nodes. In most
cases, particularly when the input slice is provided by the underlying

For cases where the origin of the input slice is unclear, the copying version
is retained. The new code performs better even when the input must be
copied, because it is now only copied once in decodeNode.

Because the goal of eth_createAccessList is providing the caller with the largest-possible
access list, it's generally not important that the gas limit used by the tracer will match the usage
of the call exactly. Avoiding the gas estimation step is a performance improvement. As long as the
call does not branch based on gas limit, the returned access list will be accurate.
This change makes http.Server.ReadHeaderTimeout configurable separately
from ReadTimeout for RPC servers. The default is set to the same as
ReadTimeout, which in order to cause no change in existing deployments.

During RPC calls such as eth_call and eth_estimateGas, st.evm.Config.NoBaseFee is set
which allows the gas price to be below the base fee. This results the tip being negative,
and balance being subtracted from the coinbase instead of added to it, which results in a
potentially negative coinbase balance interestingly. This can't happen during normal chain
processing as outside of RPC calls the gas price is required to be at least the base fee,
as NoBaseFee is false.
This change prevents this behavior by disabling fee payment when the fee is not set.

This change updates our urfave/cli dependency to the v2 branch of the library.
There are some Go API changes in cli v2:
- Flag values can now be accessed using the methods ctx.Bool,
ctx.Int, ctx.String, ... regardless of whether the flag is 'local' or
'global'.
- v2 has built-in support for flag categories. Our home-grown category
system is removed and the categories of flags are assigned as part of
the flag definition.
For users, there is only one observable difference with cli v2: flags must now
strictly appear before regular arguments. For example, the following command is
now invalid:
geth account import mykey.json --password file.txt
Instead, the command must be invoked as follows:
geth account import --password file.txt mykey.json

WIth a few exceptions.
- We use a deprecated protobuf in trezor. I didn't want to mess with that, since I cannot meaningfully test any changes there.
- The deprecated TypeMux is used in a few places still, so the warning for it is silenced for now.
- Using string type in context.WithValue is apparently wrong, one should use a custom type, to prevent collisions between different places in the hierarchy of callers. That should be fixed at some point, but may require some attention.
- The warnings for using weak random generator are squashed, since we use a lot of random without need for cryptographic guarantees.
Previously on Geth startup we just logged the chain config is a semi-json-y format. Whilst that worked while we had a handful of hard-forks defined, currently it's kind of unwieldy.
This PR converts that original data dump and converts it into a user friendly - alas multiline - log output.

This PR adds support for block overrides when doing debug_traceCall.
- Previously, debug_traceCall against pending erroneously used a common.Hash{} stateroot when looking up the state, meaning that a totally empty state was used -- so it always failed,
- With this change, we reject executing debug_traceCall against pending.
- And we add ability to override all evm-visible header fields.
In #24028 we flagged a warning when finding legacy receipts in the freezer. This PR nudges users a bit more strongly by preventing geth from starting in this case until receipts have been migrated.
It also adds a flag --ignore-legacy-receipts which when present allows geth to start normally.
#23773 added a JS tracer which uses Goja as its engine. In this PR I remove the previous tracer which used duktape as well as remove the dependencies.
This PR also comes with 2 fixes in the Goja tracer and one small behavioural change:
I had handled errors in the native Go functions by panicing. My oversight was that Goja only handles panics with a Goja.Value as argument. The difference is panic(goja.Value) allows JS to catch the exception whereas Interrupt(error) doesn't.
There was a race in how I handled Stop.
Because of 1. some of the methods that simply return nil on error (like memory.slice) now throw an exception.
This adds a JS tracer runtime environment based on the Goja VM. The new
runtime replaces the duktape runtime, which will be removed soon.
Goja is implemented in Go and is faster for cases where the Go <-> JS
transition overhead dominates overall performance. It is faster because
duktape is written in C, and the transition cost includes the cost of using
cgo. Another reason for using Goja is that go-duktape is not maintained
anymore.
We expect the performace of JS tracing to be at least as good or better with
this change.

This PR adds db tooling (geth db check-state-content) to verify the integrity of trie nodes. It iterates through the 32-byte key space in the database, which is expected to contain RLP-encoded trie nodes, addressed by hash.
* eth/protocols/snap: don't include empty snapshot slot slice
This PR fixes the snapshot storage serving handler. In snap protocol
the response is capped by the response size. Server can cutdown the
response if the accumulated byte size exceeds the local hard limit.
It means we can meet a special scenario that there is no storage slot
included for a requested account, but we attach the proof for this
account by mistake.
So in the prover side, when it meets a empty storage response but with
a valid proof proves there are some more slots left in the trie, then
requestor will reject this response and disconnect with server.
In this PR, if there is no storage slot served for the requested account,
then no proof should be attached as well.

Previously freezer has only been used for storing ancient chain data, while obviously it can be used more. This PR unties the chain data and freezer, keep the minimal freezer structure and move all other logic (like incrementally freezing block data) into a separate structure called ChainFreezer.
This PR also extends the database interface by adding a new ancient store function AncientDatadir which can return the root directory of ancient store. The ancient root directory can be used when we want to open some other ancient-stores (e.g. reverse diff freezer).
During mining, when a new head arrives and interrupts the block building, the block being built should not be commited (but discarded). Committing the interrupted block introduces unnecessary delay, and possibly causes miner to mine on the previous head, which could result in higher uncle rate.

This PR groups all built-in network flags together and list them in the command as a whole.
And all database path flags(datadir, ancient) are also grouped, since usually these two are
used together.
This adds the ability to run --state.fork=Merged, and have post-merge rules apply. When doing so, it also requires the input env to contain currentRandom, and enforces the currentDifficulty to be omitted or zero.
This PR fixes up the example python clef wrapper. The poc is intended to demonstrate how to wite a UI for clef, and had severely bitrotted.
With these changes, it "works" in the sense that all the built-in tests triggers the intended python callbacks (no errors about method not found). It does not "work" in the sense that the wrapper can be used as an actual UI. It will auto-reject any signing requests, for example.
This PR fixes the flaw that @rjl493456442 found in https://github.com/ethereum/go-ethereum/pull/#issuecomment-1093817551 , namely, that the snapshot iterator uses the combined (disk + difflayers) 'view', wheres the raw iterator uses only the disk 'view'.
This PR instead splits up the work: one phase is iterating the disk layer data, another phase is loading the journalled difflayers and performing the same check there.
This change removes extraneous/unnecessary checks for equality
when comparing 2 accessList values A and B. Given that we validate that
their lengths of A and B are equal, if so and if every element in A is
in B, reflexively every element in B is already in A. If that weren't
the case and an element g existed in A but not in B, that would mean
that there is an extra element and hence a mathematical contradiction.

If a pending contract call errors, return that error right away rather
than ignoring it to allow an error somewhere else. This is helpful for
callers to know if perhaps a call failed because of the context deadline
being expired. This change mirrors the behavior of non-pending contract
calls.
This PR fixes a few panics in the chain marker benchmarks. The root
cause for panic is in chain marker the genesis header/block is not
accessible, while it's expected to be obtained in tests. So this PR
avoids touching genesis header at all to avoid panic.
This commit replaces ioutil.TempDir with t.TempDir in tests. The
directory created by t.TempDir is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using ioutil.TempDir
had to be removed manually by calling os.RemoveAll, which is omitted in
some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but t.TempDir handles this for us nicely.

This change speeds up trie hashing and all other activities that require
RLP encoding of trie nodes by approximately 20%. The speedup is achieved by
avoiding reflection overhead during node encoding.
The interface type trie.node now contains a method 'encode' that works with
rlp.EncoderBuffer. Management of EncoderBuffers is left to calling code.
trie.hasher, which is pooled to avoid allocations, now maintains an
EncoderBuffer. This means memory resources related to trie node encoding
are tied to the hasher pool.

This change makes use of the new code generator rlp/rlpgen to improve the
performance of RLP encoding for Header and StateAccount. It also speeds up
encoding of ReceiptForStorage using the new rlp.EncoderBuffer API.
The change is much less transparent than I wanted it to be, because Header and
StateAccount now have an EncodeRLP method defined with pointer receiver. It
used to be possible to encode non-pointer values of these types, but the new
method prevents that and attempting to encode unadressable values (even if
part of another value) will return an error. The error can be surprising and may
pop up in places that previously didn't expect any errors.
To make things work, I also needed to update all code paths (mostly in unit tests)
that lead to encoding of non-pointer values, and pass a pointer instead.

This change adds a code generator tool for creating EncodeRLP method
implementations. The generated methods will behave identically to the
reflect-based encoder, but run faster because there is no reflection overhead.
Package rlp now provides the EncoderBuffer type for incremental encoding. This
is used by generated code, but the new methods can also be useful for
hand-written encoders.
There is also experimental support for generating DecodeRLP, and some new
methods have been added to the existing Stream type to support this. Creating
decoders with rlpgen is not recommended at this time because the generated
methods create very poor error reporting.
More detail about package rlp changes:
* rlp: externalize struct field processing / validation
This adds a new package, rlp/internal/rlpstruct, in preparation for the
RLP encoder generator.
I think the struct field rules are subtle enough to warrant extracting
this into their own package, even though it means that a bunch of
adapter code is needed for converting to/from rlpstruct.Type.
* rlp: add more decoder methods (for rlpgen)
This adds new methods on rlp.Stream:
- Uint64, Uint32, Uint16, Uint8, BigInt
- ReadBytes for decoding into []byte
- MoreDataInList - useful for optional list elements
* rlp: expose encoder buffer (for rlpgen)
This exposes the internal encoder buffer type for use in EncodeRLP
implementations.
The new EncoderBuffer type is a sort-of 'opaque handle' for a pointer to
encBuffer. It is implemented this way to ensure the global encBuffer pool
is handled correctly.
This PR adds an addtional API called `NewBatchWithSize` for db
batcher. It turns out that leveldb batch memory allocation is
super inefficient. The main reason is the allocation step of
leveldb Batch is too small when the batch size is large. It can
take a few second to build a leveldb batch with 100MB size.
Luckily, leveldb also offers another API called MakeBatch which can
pre-allocate the memory area. So if the approximate size of batch is
known in advance, this API can be used in this case.
It's needed in new state scheme PR which needs to commit a batch of
trie nodes in a single batch. Implement the feature in a seperate PR.
This functionality is needed in new path-based storage scheme, but
can be implemented in a seperate PR though.
When an account is deleted, then all the storage slots should be
nuked out from the disk as well. In hash-based storage scheme they
are still left in the disk but in new scheme, they will be iterated
and marked as deleted.
But why the NodeBlob API is needed in this scenario? Because when
the node is marked deleted, the previous value is also required to
be recorded to construct the reverse diff.
This change makes it so WaitMined no longer logs an error when the receipt
is unavailable. It also changes the simulated backend to return NotFound for
unavailable receipts, just like ethclient does.
I believe the sentence is attempting to explain that the URL is "[used] by upper layers to define a sorting order over all wallets from multiple backends."

When talking to an HTTP2 server, there are situations where it needs to

SyncProgress was modified in PR #23576 to add the fields reported for
snap sync. The PR also changed ethclient to use the SyncProgress struct
directly instead of wrapping it for hex-decoding. This broke the
SyncProgress method.
Fix it by putting back the custom wrapper. While here, also put back the
fast sync related fields because SyncProgress is stable API and thus
removing fields is not allowed.

New behaviour is that the endpoint returns results only for available
blocks without returning an error when it doesn't find a block. Note we
skip any block after a non-existent block.
This adds a header fetch for every block in range (even if header
is not needed). Alternatively, we could do the check in every field's
resolver method to avoid this overhead.

This PR reduces the amount of work we do when answering header queries, e.g. when a peer
is syncing from us.
For some items, e.g block bodies, when we read the rlp-data from database, we plug it
directly into the response package. We didn't do that for headers, but instead read
headers-rlp, decode to types.Header, and re-encode to rlp. This PR changes that to keep it
in RLP-form as much as possible. When a node is syncing from us, it typically requests 192
contiguous headers. On master it has the following effect:
- For headers not in ancient: 2 db lookups. One for translating hash->number (even though
the request is by number), and another for reading by hash (this latter one is sometimes
cached).
- For headers in ancient: 1 file lookup/syscall for translating hash->number (even though
the request is by number), and another for reading the header itself. After this, it
also performes a hashing of the header, to ensure that the hash is what it expected. In
this PR, I instead move the logic for "give me a sequence of blocks" into the lower
layers, where the database can determine how and what to read from leveldb and/or
ancients.
There are basically four types of requests; three of them are improved this way. The
fourth, by hash going backwards, is more tricky to optimize. However, since we know that
the gap is 0, we can look up by the parentHash, and stlil shave off all the number->hash
lookups.
The gapped collection can be optimized similarly, as a follow-up, at least in three out of
four cases.

This PR fixes a special corner case in transaction indexing.
When the chain is rewound by SetHead to a historical point which is even lower than the transaction indexes tail, then system will report Failed to decode block body error all the time, because the relevant blocks are already deleted.
In order to avoid this "non-critical-but-annoying" issue, we can recap the indexing target to head+1(to is excluded, so it means indexing transactions from 0 to head).

Trim the search key from head as it's being pushed deeper into the trie. Previously the search key was never modified but each node kept information how to slice and compare it in keyOffset. Now the keyOffset is not needed as this information is included in the slice of the search key. This way the keyOffset can be removed and key manipulation
simplified.

- Make the output more detailed about what is returned (always print packet kind).

Debugging recent geth failures in hive, it took a while to realize that it's because
geth doesn't support eth/65 any longer. This PR makes such failures a bit more
easy to figure out.
The price limit is supposed to exclude transactions with too low fee
amount. Before EIP-1559, it was sufficient to check the limit against
the gas price of the transaction. After 1559, it is more complicated
because the concept of 'transaction gas price' does not really exist.
When mining, the price limit is used to exclude transactions below a
certain effective fee amount. This change makes it apply the same check
earlier, in tx validation. Transactions below the specified fee amount
cannot enter the pool.
Fixes#23837
This PR fixes a problem which arises on clique networks when there is a network stall. Previously, the worker packages were tracked, even if the sealing engine decided not to seal the block (due to clique rules about recent signing). These tracked-but-not-sealed blocks kept building up in memory.
This PR changes the situation so the sealing engine instead returns an error, and the worker can thus un-track the package.
This avoids quadratic time complexity in the lookup of the batch element
corresponding to an RPC response. Unfortunately, the new approach
requires additional memory for the mapping from ID to index.
Fixes#22805
When we map a file for generating the DAG, we do a simple truncate to e.g. 1Gb. This is fine, even if we have nowhere near 1Gb disk available, as the actual file doesn't take up the full 1Gb, merely a few bytes. When we start generating into it, however, it eventually crashes with a unexpected fault address .
This change fixes it (on linux systems) by using the Fallocate syscall, which preallocates suffcient space on disk to avoid that situation.

This PR offers two more database sub commands for exporting and importing data.
Two exporters are implemented: preimage and snapshot data respectively.
The import command is generic, it can take any data export and import into leveldb.
The data format has a 'magic' for disambiguation, and a version field for future compatibility.
It is because write known block only checks block and state without snapshot, which could lead to gap between newest snapshot and newest block state. However, new blocks which would cause snapshot to become fixed were ignored, since state was already known.

Some benchmarks in eth/filters were not good: they weren't reproducible, relying on geth chaindata to be present.
Another one was rejected because the receipt was lacking a backing transcation.
The p2p simulation benchmark had a lot of the warnings below, due to the framework calling both
Stop() and Close(). Apparently, the simulated adapter is the only implementation which has a Close(),
and there is no need to call both Stop and Close on it.

fast-sync quickly to the current state of the network. To do so:
