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 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.
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 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
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.
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...
* core/types: add data gas fields in Receipt
* core/types: use BlobGas method of tx
* core: fix test
* core/types: fix receipt tests, add data gas used field test

The EIP150Hash was an idea where, after the fork, we hardcoded the forked hash as an extra defensive mechanism. It wasn't really used, since forks weren't contentious and for all the various testnets and private networks it's been a hassle to have around.
This change removes that config field.

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.
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 change implements withdrawals as specified in EIP-4895.

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.
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.
