* 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 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.
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.

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.

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 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 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 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.

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.

Verkle trees store the code inside the trie. This PR changes the interface to pass the code, as well as the dirty flag to tell the trie package if the code is dirty and needs to be updated. This is a no-op for the MPT and the odr trie.
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 changes the journal logic to mark the state object dirty immediately when it
is reset.
We're mostly adding this change to appease the fuzzer. Marking it dirty immediately
makes no difference in practice because accounts will always be modified by EVM
right after creation.
Continuing with a series of PRs to make the Trie interface more generic, this PR moves
the RLP encoding of storage slots inside the StateTrie and light.Trie implementations,
as other types of tries don't use RLP.
This PR adds a staleness-check to AccountRLP, before checking the bloom-filter and potentially going directly into the disklayer.

In this PR, all TryXXX(e.g. TryGet) APIs of trie are renamed to XXX(e.g. Get) with an error returned.

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.

Currently, most of transaction validation while holding the txpool mutex: one exception being an early-on signature check.

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.
The meter for "for measuring the effective amount of data read" within the freezertable was never updated. This change remedies that.

When interacting with geth as a library to e.g. produce state tests, it is desirable to obtain the consensus-correct jumptable definition for a given fork. This changes adds accessors so the instructionset can be obtained and characteristics about opcodes can be inspected.
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 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.
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 ports some changes from the main PBSS PR:
- get rid of callback function in `trie.Database.Commit` which is not required anymore
- rework the `nodeResolver` in `trie.Iterator` to make it compatible with multiple state scheme
- some other shallow changes in tests and typo-fixes
This PR moves core/beacon to beacon/engine so that beacon-chain related code has its own top level package which also can house the the beacon lightclient-code.
This PR moves some trie-related db accessor methods to a different file, and also removes the schema type. Instead of the schema type, a string is used to distinguish between hashbased/pathbased db accessors.
This also moves some code from trie package to rawdb package.
This PR is intended to be a no-functionality-change prep PR for #25963 .

This change improves reusability of the EVM struct. Two methods are added:
- SetBlockContext(...)
- SetTracer(...)
Other attributes like the TransactionContext and the StateDB can already be updated.
BlockContext and Tracer are partially not updateable right now. This change fixes it and
opens the potential to reuse an EVM struct in more ways.

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.

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.

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.

This PR removes the notion of fakeStorage from the state objects, and instead, for any state modifications that are needed, it simply makes the changes.
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
is not available. It used to return an 'empty trie' in this case, but that's
not possible anymore under PBSS.
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 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.
A comment suggests that contract creation happens if the recipient of a call is 0x00..00 ("zero address") but in fact the sender must be nil. The zero address is a regular valid address that is commonly used as a "burn" address.
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.
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.
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
While investigating #22374, I noticed that the Sync operation of the
freezer does not take the table lock. It also doesn't call sync for all files
if there is an error with one of them. I doubt this will fix anything, but
didn't want to drop the fix on the floor either.
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.
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.
Closes: #26136

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 PR ports a few changes from PBSS:
- Fix the snapshot generator waiter in case the generation is not even initialized
- Refactor db inspector for ancient store
This PR fixes a regression causing snapshots not to be generated in "geth --import" mode. It also fixes the geth export command to be truly readonly, and adds a new test for geth export.
This adds a
* core/vm, tests: optimized modexp + fuzzer
* common/math: modexp optimizations
* core/vm: special case base 1 in big modexp
* core/vm: disable fastexp
This changes the error message for mismatching chain ID to show
the given and expected value. Callers expecting this error must be
changed to use errors.Is.
* ethclient/gethclient: improve time-sensitive flaky test
* eth/catalyst: fix (?) flaky test
* core: stop blockchains in tests after use
* core: fix dangling blockchain instances
* core: rm whitespace
* eth/gasprice, eth/tracers, consensus/clique: stop dangling blockchains in tests
* all: address review concerns
* core: goimports
* eth/catalyst: fix another time-sensitive test
* consensus/clique: add snapshot test run function
* core: rename stop() to stopWithoutSaving()

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.
`geth dumpgenesis` currently does not respect the content of the data directory. Instead, it outputs the genesis block created by command-line flags. This PR fixes it to read the genesis from the database, if the database already exists.

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.
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.
This PR makes the event-sending for deleted and new logs happen in batches, to prevent OOM situation due to large reorgs.

This PR allows users to pass in a config object directly to the tracers. Previously only the struct logger was configurable.
It also adds an option to the call tracer which if enabled makes it ignore any subcall and collect only information about the top-level call. See #25419 for discussion.
The tracers will silently ignore if they are passed a config they don't care about.
