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.
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.
This change updates `evm b11r` (blockbuilder) and `evm t8n` (transition) tools to contain cancun updates (e.g. new header fields)

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.
Sets the `currentExcessBlobGas` from env, alternatively calculates it based on `parentExcessBlobGas` and `parentBlobGasUsed`. It then emits the `currentExcessBlobGas` and `currentBlobGasUsed` into the output, to be used as parent-values for a future iteration.
Closes#27785Closes#27783

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 PR removes the Debug field from vmconfig, making it so that if a tracer is set, debug=true is implied.

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 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 change implements withdrawals as specified in EIP-4895.

This PR changes the API so that uint64 is used for fork timestamps.
It's a good choice because types.Header also uses uint64 for time.

Currently, in order to chain together sequential valid t8n transitions the caller must manually calculate the block base fee. This PR adds support for the necessary parent fee market data to calculate the base fee for the current transition.
Concretely, env is extended to accept the following:
parentBaseFee
parentGasUsed
parentGasLimit
Example usage can be found in ./cmd/evm/testdata/25.

This adds a tools.go file to import all command packages used for
go:generate. Doing so makes it possible to execute go-based code
generators using 'go run', locking in the tool version using go.mod.

* core: implement eip-4399 random opcode
* core: make vmconfig threadsafe
* core: miner: pass vmConfig by value not reference
* all: enable 4399 by Rules

* cmd/evm/internal/t8ntool: fix t8n tracing of 4399
* tests: set difficulty
* cmd/evm/internal/t8ntool: check that baserules are london before applying the merge chainrules
This PR adds functionality to the evm t8n to calculate ethash difficulty. If the caller does not provide a currentDifficulty, but instead provides the parentTimestamp (well, semi-optional, will default to 0 if not given), and parentDifficulty, we can calculate it for him.
The caller can also provide a parentUncleHash. In most, but not all cases, the parent uncle hash also affects the formula. If no such hash is provided (or, if the empty all-zero hash is provided), it's assumed that there were no uncles.
This is the initial implementation of EIP-1559 in packages core/types and core.
Mining, RPC, etc. will be added in subsequent commits.

This adds support for EIP-2718 typed transactions as well as EIP-2930
access list transactions (tx type 1). These EIPs are scheduled for the
Berlin fork.
There very few changes to existing APIs in core/types, and several new APIs
to deal with access list transactions. In particular, there are two new
constructor functions for transactions: types.NewTx and types.SignNewTx.
Since the canonical encoding of typed transactions is not RLP-compatible,
Transaction now has new methods for encoding and decoding: MarshalBinary
and UnmarshalBinary.
The existing EIP-155 signer does not support the new transaction types.
All code dealing with transaction signatures should be updated to use the
newer EIP-2930 signer. To make this easier for future updates, we have
added new constructor functions for types.Signer: types.LatestSigner and
types.LatestSignerForChainID.
This change also adds support for the YoloV3 testnet.

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
Removes the yolov2 definition, adds yolov3, including EIP-2565. This PR also disables some of the erroneously generated blockchain and statetests, and adds the new genesis hash + alloc for yolov3.
This PR disables the CLI switches for yolo, since it's not complete until we merge support for 2930.
* all: core: split vm.Config into BlockConfig and TxConfig
* core: core/vm: reset EVM between tx in block instead of creating new
* core/vm: added docs
This PR implements the EVM state transition tool, which is intended
to be the replacement for our retesteth client implementation.
Documentation is present in the cmd/evm/README.md file.
