The EmptyRootHash and EmptyCodeHash are defined everywhere in the codebase, this PR replaces all of them with unified one defined in core/types package, and also defines constants for TxRoot, WithdrawalsRoot and UncleRoot
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`rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.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 builds on #26299, but also updates the tests to the most recent version, which includes tests regarding TheMerge.
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.
When new block is imported, there is no need to commit the current
work, even the new imported block is offturn and itself is inturn.
That is because when offturn block is received, the inturn block is
already later to broadcast block, deliver the later block will cause
many reorg, which is not reasonable.
And also make sure all useless work can be discarded, to avoid goroutine leak.
Currently, validator only try once to get transactions from TxPool to produce the block.
However, new transactions could arrive while the validator is committing transaction.
Validator should be allowed to add these new arrived transactions as long as
Header.Timestamp is not reached
This commit will:
** commitTransactions return with error code
** drop current mining block on new block imported
** try fillTransactions several times for the best
not use append mode to follow the GasPrice rule.
** check if there is enough time for another fillTransactions.
Right now, DelayLeftOver is used to reserve time for block finalize, not block
broadcast. And the code does not work as expected.
The general block generation could be described as:
|- fillTransactions -|- finalize a block -|- wait until the period(3s) reached -|- broadcast -|
This PR changes geth to read the eip1559 params from the chain config instead of the globals.
This way the parameters may be changed by forking the chain config code, without creating a large diff throughout the past and future usages of the parameters.

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.
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 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.
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 removes some code:
- The clique engine calculated the snapshot twice when verifying headers/blocks.
- The method GetBlockHashesFromHash in Header/Block/Lightchain was only used by tests. It
is now removed from the API.
- The method GetTdByHash internally looked up the number before calling GetTd(hash, num).
In many cases, callers already had the number, and used this method just because it has a
shorter name. I have removed the method to make the API surface smaller.

The PR implements the --miner.notify.full flag that enables full pending block
notifications. When this flag is used, the block notifications sent to mining
endpoints contain the complete block header JSON instead of a work package
array.

The PR makes use of the stacktrie, which is is more lenient on resource consumption, than the regular trie, in cases where we only need it for DeriveSha
This PR implements the following modifications
- Don't shortcut check if block is present, thus avoid disk lookup
- Don't check hash ancestry in early-check (it's still done in parallel checker)
- Don't check time.Now for every single header
Charts and background info can be found here: https://github.com/holiman/headerimport/blob/main/README.md
With these changes, writing 1M headers goes down to from 80s to 62s.
This PR adds re-written difficulty calculators, which are based on uint256. It also adds a fuzzer + oss-fuzz integration for the new fuzzer. It does differential fuzzing between the new and old calculators.
Note: this PR does not actually enable the new calculators.

The original idea behind this change was to remove a use of the
deprecated CancelRequest method. Simply removing it would've been an
option, but I couldn't resist and did a bit of a refactoring instead.
All remote sealing code was contained in a single giant function. Remote
sealing is now extracted into its own object, remoteSealer.
This PR introduces clique_status which gives info about the health of
the clique network.
It's currently a bit PITA to find out how a clique network is
performing, and it can easily happen that sealers drop off -- and
everything is 'fine' until one more signer drops off, and the network
suddenly halts.
The new method provides the following stats:
- Which signers are currently active, and have signed blocks in the last
N (set to 64) blocks?
- How many blocks has each signer signed?
- What is the difficulty in the last N blocks, compared to the
theoretical maximum?
