For PeerDAS, we need to compute cell proofs. Both ckzg and gokzg support
computing these cell proofs.
This PR does the following:
- Update the go-kzg library from "github.com/crate-crypto/go-kzg-4844"
to "github.com/crate-crypto/go-eth-kzg" which will be the new upstream
for go-kzg moving forward
- Update ckzg from v1.0.0 to v2.0.1 and switch to /v2
- Updates the trusted setup to contain the g1 points both in lagrange
and monomial form
- Expose `ComputeCells` to compute the cell proofs
I added the history mode configuration in eth/ethconfig initially, since
it seemed like the logical place. But it turns out we need access to the
intended pruning setting at a deeper level, and it actually needs to be
integrated with the blockchain startup procedure.
With this change applied, if a node previously had its history pruned,
and is subsequently restarted **without** the `--history.chain
postmerge` flag, the `BlockChain` initialization code will now verify
the freezer tail against the known pruning point of the predefined
network and will restore pruning status. Note that this logic is quite
restrictive, we allow non-zero tail only for known networks, and only
for the specific pruning point that is defined.
This PR adds a new `--beacon.checkpoint.file` config flag to geth and
blsync which specifies a checkpoint import/export file. If a file with
an existing checkpoint is specified, it is used for initialization
instead of the hardcoded one (except when `--beacon.checkpoint` is also
specified simultaneously). Whenever the client encounters a new valid
finality update with a suitable finalized beacon block root at an epoch
boundary, it saves the block root in hex format to the checkpoint file.
This adds the test description text to the output, instead of keeping it
as a Go comment. Logs are visible in the hive UI where these tests run,
while Go comments are not.
This pull request introduces new sync logic for pruning mode. The downloader will now skip
insertion of block bodies and receipts before the configured history cutoff point.
Originally, in snap sync, the header chain and other components (bodies and receipts) were
inserted separately. However, in Proof-of-Stake, this separation is unnecessary since the
sync target is already verified by the CL.
To simplify the process, this pull request modifies `InsertReceiptChain` to insert headers
along with block bodies and receipts together. Besides, `InsertReceiptChain` doesn't have
the notion of reorg, as the common ancestor is always be found before the sync and extra
side chain is truncated at the beginning if they fall in the ancient store. The stale
canonical chain flags will always be rewritten by the new chain. Explicit reorg logic is
no longer required in `InsertReceiptChain`.
This adds a new subcommand 'geth prune-history' that removes the pre-merge history
on supported networks. Geth is not fully ready to work in this mode, please do not run
this command on your production node.

This PR fixes the broken request error handling of the workload filter
tests. Until now `validateHistoryPruneErr` was invoked with `fq.Err` as
an input which was always nil and a timeout or http error was reported
as a result content mismatch.
Also, in case of `errPrunedHistory` it is wrong to return here without
setting an error because then it will look like a valid empty result and
the check will later fail. So instead `errPrunedHistory` is always
returned now (without printing an error message) and the callers of
`run` should handle this special case (typically ignore silently).
This removes the signer type-train in favor of defining a single object
that can handle all tx types. Supported types are enabled via a map.
Notably, the new signer also supports disabling legacy transactions.
When I'm running `geth import --metrics`, the metrics is different to
normal `geth --metrics`, so the grafana dashboard needs to be updated,
eg: `eth_db_chaindata_disk_read` vs `disk_read`.
So I think we should always set the name to `eth/db/chaindata` for more
convenient.

This PR implements a new version of the abigen utility (v2) which exists
along with the pre-existing v1 version.
Abigen is a utility command provided by go-ethereum that, given a
solidity contract ABI definition, will generate Go code to transact/call
the contract methods, converting the method parameters/results and
structures defined in the contract into corresponding Go types. This is
useful for preventing the need to write custom boilerplate code for
contract interactions.
Methods in the generated bindings perform encoding between Go types and
Solidity ABI-encoded packed bytecode, as well as some action (e.g.
`eth_call` or creating and submitting a transaction). This limits the
flexibility of how the generated bindings can be used, and prevents
easily adding new functionality, as it will make the generated bindings
larger for each feature added.
Abigen v2 was conceived of by the observation that the only
functionality that generated Go bindings ought to perform is conversion
between Go types and ABI-encoded packed data. Go-ethereum already
provides various APIs which in conjunction with conversion methods
generated in v2 bindings can cover all functionality currently provided
by v1, and facilitate all other previously-desired use-cases.
## Generating Bindings
To generate contract bindings using abigen v2, invoke the `abigen`
command with the `--v2` flag. The functionality of all other flags is
preserved between the v2 and v1 versions.
## What is Generated in the Bindings
The execution of `abigen --v2` generates Go code containing methods
which convert between Go types and corresponding ABI-encoded data
expected by the contract. For each input-accepting contract method and
the constructor, a "packing" method is generated in the binding which
converts from Go types to the corresponding packed solidity expected by
the contract. If a method returns output, an "unpacking" method is
generated to convert this output from ABI-encoded data to the
corresponding Go types.
For contracts which emit events, an unpacking method is defined for each
event to unpack the corresponding raw log to the Go type that it
represents.
Likewise, where custom errors are defined by contracts, an unpack method
is generated to unpack raw error data into a Go type.
## Using the Generated Bindings
For a smooth user-experience, abigen v2 comes with a number of utility
functions to be used in conjunction with the generated bindings for
performing common contract interaction use-cases. These include:
* filtering for historical logs of a given topic
* watching the chain for emission of logs with a given topic
* contract deployment methods
* Call/Transact methods
https://geth.ethereum.org will be updated to include a new tutorial page
for abigen v2 with full code examples. The page currently exists in a
PR: https://github.com/ethereum/go-ethereum/pull/31390 .
There are also extensive examples of interactions with contract bindings
in [test
cases](cc855c7ede/accounts/abi/bind/v2/lib_test.go)
provided with this PR.

this adds 2 features to improve `geth --dev` experience.
1. we don't need to use `dev_SetFeeRecipient` to set initial coinbase
address. it was a pain.
2. we don't need to unlock keystore if we don't use it. we had it
because of clique.
Fixes `evm statetest` for state test fixtures with multiple fork entries
in their `post` field (e.g.,
[chainId.json](81862e4848/GeneralStateTests/stChainId/chainId.json (L39))).
When these re-activated flags aren't exposed, `statetest` only executes
the fixture for a single fork entry instead of all of the forks as
expected.
This only affects ethereum/tests state test fixtures, not
ethereum/execution-spec-tests (EEST) state tests. EEST writes a separate
fixture/test case (i.e. a separate top-level dict entry in the .json)
for each fork configuration as apposed to combining multiple forks in
one fixture test case: New EEST state tests targeting Prague behavior
are not affected.

Here I am adding a config option and geth flag (`--history.chain`) for
configuring history pruning. There are two options available:
- `--history.chain all` is the default and will keep all history like
before.
- `--history.chain postmerge` will configure the history cutoff point to
the merge block.
The option doesn't actually do anything right now, but we need it as a
precursor for other history pruning changes.
When I press Ctrl-C during the import of multiple files, the import
process will still attempt to import the subsequent files. However, in
normal circumstances, users would expect the import to stop immediately
upon pressing Ctrl-C.
And because the current file was not finished importing, subsequent
import tasks often fail due to an `unknown ancestor` error.

This ensures that if we receive a blob transaction announcement where we cannot
link the tx to the sidecar commitments, we will drop the sending peer. This check
is added in the protocol handler for the PooledTransactions message.
Tests for this have also been added in the cross-client "eth" protocol test suite.

This is a not-particularly-important "cleanliness" PR. It removes the
last remnants of the `x/exp` package, where we used the `maps.Keys`
function.
The original returned the keys in a slice, but when it became 'native'
the signature changed to return an iterator, so the new idiom is
`slices.Collect(maps.Keys(theMap))`, unless of course the raw iterator
can be used instead.
In some cases, where we previously collect into slice and then sort, we
can now instead do `slices.SortXX` on the iterator instead, making the
code a bit more concise.
This PR might be _slighly_ less optimal, because the original `x/exp`
implementation allocated the slice at the correct size off the bat,
which I suppose the new code won't.
Putting it up for discussion.

Currently, when calculating block's bloom, we loop through all the
receipt logs to calculate the hash value. However, normally, after going
through applyTransaction, the receipt's bloom is already calculated
based on the receipt log, so the block's bloom can be calculated by just
ORing these receipt's blooms.

After recent changes in Geth (removing TD):
39638c81c5 (diff-d70a44d4b7a0e84fe9dcca25d368f626ae6c9bc0b8fe9690074ba92d298bcc0d)
Non-Geth clients are failing many devp2p tests with an error:
`peering failed: status exchange failed: wrong TD in status: have 1 want 0`
Right now only Geth is passing it - all other clients are affected by
this change. I think there should be no validation of TD when checking `Status`
message in hive tests. Now Geth has 0 (and hive tests requires 0) and
all other clients have actual TD. And on real networks there is no validation
of TD when peering
Here we add some more changes for live tracing API v1.1:
- Hook `OnSystemCallStartV2` was introduced with `VMContext` as parameter.
- Hook `OnBlockHashRead` was introduced.
- `GetCodeHash` was added to the state interface
- The new `WrapWithJournal` construction helps with tracking EVM reverts in the tracer.

This PR changes the signature of `CalcExcessBlobGas` to take in just
the header timestamp instead of the whole object. It also adds a sanity
check for the parent->child block order to `VerifyEIP4844Header`.
A clarification was made to EIP-7691 stating that at the fork boundary
it is required to use the target blob count associated with the head
block, rather than the parent as implemented here.

The total difficulty is the sum of all block difficulties from genesis
to a certain block. This value was used in PoW for deciding which chain
is heavier, and thus which chain to select. Since PoS has a different
fork selection algorithm, all blocks since the merge have a difficulty
of 0, and all total difficulties are the same for the past 2 years.
Whilst the TDs are mostly useless nowadays, there was never really a
reason to mess around removing them since they are so tiny. This
reasoning changes when we go down the path of pruned chain history. In
order to reconstruct any TD, we **must** retrieve all the headers from
chain head to genesis and then iterate all the difficulties to compute
the TD.
In a world where we completely prune past chain segments (bodies,
receipts, headers), it is not possible to reconstruct the TD at all. In
a world where we still keep chain headers and prune only the rest,
reconstructing it possible as long as we process (or download) the chain
forward from genesis, but trying to snap sync the head first and
backfill later hits the same issue, the TD becomes impossible to
calculate until genesis is backfilled.
All in all, the TD is a messy out-of-state, out-of-consensus computed
field that is overall useless nowadays, but code relying on it forces
the client into certain modes of operation and prevents other modes or
other optimizations. This PR completely nukes out the TD from the node.
It doesn't compute it, it doesn't operate on it, it's as if it didn't
even exist.
Caveats:
- Whenever we have APIs that return TD (devp2p handshake, tracer, etc.)
we return a TD of 0.
- For era files, we recompute the TD during export time (fairly quick)
to retain the format content.
- It is not possible to "verify" the merge point (i.e. with TD gone, TTD
is useless). Since we're not verifying PoW any more, just blindly trust
it, not verifying but blindly trusting the many year old merge point
seems just the same trust model.
- Our tests still need to be able to generate pre and post merge blocks,
so they need a new way to split the merge without TTD. The PR introduces
a settable ttdBlock field on the consensus object which is used by tests
as the block where originally the TTD happened. This is not needed for
live nodes, we never want to generate old blocks.
- One merge transition consensus test was disabled. With a
non-operational TD, testing how the client reacts to TTD is useless, it
cannot react.
Questions:
- Should we also drop total terminal difficulty from the genesis json?
It's a number we cannot react on any more, so maybe it would be cleaner
to get rid of even more concepts.
