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

the given and expected value. Callers expecting this error must be
changed to use errors.Is.

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.

During RPC calls such as eth_call and eth_estimateGas, st.evm.Config.NoBaseFee is set
which allows the gas price to be below the base fee. This results the tip being negative,
and balance being subtracted from the coinbase instead of added to it, which results in a
potentially negative coinbase balance interestingly. This can't happen during normal chain
processing as outside of RPC calls the gas price is required to be at least the base fee,
as NoBaseFee is false.
This change prevents this behavior by disabling fee payment when the fee is not set.

This enables the following linters
- typecheck
- unused
- staticcheck
- bidichk
- durationcheck
- exportloopref
- gosec
WIth a few exceptions.
- We use a deprecated protobuf in trezor. I didn't want to mess with that, since I cannot meaningfully test any changes there.
- The deprecated TypeMux is used in a few places still, so the warning for it is silenced for now.
- Using string type in context.WithValue is apparently wrong, one should use a custom type, to prevent collisions between different places in the hierarchy of callers. That should be fixed at some point, but may require some attention.
- The warnings for using weak random generator are squashed, since we use a lot of random without need for cryptographic guarantees.
Previously on Geth startup we just logged the chain config is a semi-json-y format. Whilst that worked while we had a handful of hard-forks defined, currently it's kind of unwieldy.
This PR converts that original data dump and converts it into a user friendly - alas multiline - log output.
This PR adds support for block overrides when doing debug_traceCall.
- Previously, debug_traceCall against pending erroneously used a common.Hash{} stateroot when looking up the state, meaning that a totally empty state was used -- so it always failed,
- With this change, we reject executing debug_traceCall against pending.
- And we add ability to override all evm-visible header fields.
This adds a JS tracer runtime environment based on the Goja VM. The new
runtime replaces the duktape runtime, which will be removed soon.
Goja is implemented in Go and is faster for cases where the Go <-> JS
transition overhead dominates overall performance. It is faster because
duktape is written in C, and the transition cost includes the cost of using
cgo. Another reason for using Goja is that go-duktape is not maintained
anymore.
We expect the performace of JS tracing to be at least as good or better with
this change.
Previously freezer has only been used for storing ancient chain data, while obviously it can be used more. This PR unties the chain data and freezer, keep the minimal freezer structure and move all other logic (like incrementally freezing block data) into a separate structure called ChainFreezer.
This PR also extends the database interface by adding a new ancient store function AncientDatadir which can return the root directory of ancient store. The ancient root directory can be used when we want to open some other ancient-stores (e.g. reverse diff freezer).

This PR fixes the flaw that @rjl493456442 found in https://github.com/ethereum/go-ethereum/pull/#issuecomment-1093817551 , namely, that the snapshot iterator uses the combined (disk + difflayers) 'view', wheres the raw iterator uses only the disk 'view'.
This PR instead splits up the work: one phase is iterating the disk layer data, another phase is loading the journalled difflayers and performing the same check there.
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.

This PR fixes a few panics in the chain marker benchmarks. The root
cause for panic is in chain marker the genesis header/block is not
accessible, while it's expected to be obtained in tests. So this PR
avoids touching genesis header at all to avoid panic.
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 change makes use of the new code generator rlp/rlpgen to improve the
performance of RLP encoding for Header and StateAccount. It also speeds up
encoding of ReceiptForStorage using the new rlp.EncoderBuffer API.
The change is much less transparent than I wanted it to be, because Header and
StateAccount now have an EncodeRLP method defined with pointer receiver. It
used to be possible to encode non-pointer values of these types, but the new
method prevents that and attempting to encode unadressable values (even if
part of another value) will return an error. The error can be surprising and may
pop up in places that previously didn't expect any errors.
To make things work, I also needed to update all code paths (mostly in unit tests)
that lead to encoding of non-pointer values, and pass a pointer instead.

This PR adds an addtional API called `NewBatchWithSize` for db
batcher. It turns out that leveldb batch memory allocation is
super inefficient. The main reason is the allocation step of
leveldb Batch is too small when the batch size is large. It can
take a few second to build a leveldb batch with 100MB size.
Luckily, leveldb also offers another API called MakeBatch which can
pre-allocate the memory area. So if the approximate size of batch is
known in advance, this API can be used in this case.
It's needed in new state scheme PR which needs to commit a batch of
trie nodes in a single batch. Implement the feature in a seperate PR.

This PR reduces the amount of work we do when answering header queries, e.g. when a peer
is syncing from us.
For some items, e.g block bodies, when we read the rlp-data from database, we plug it
directly into the response package. We didn't do that for headers, but instead read
headers-rlp, decode to types.Header, and re-encode to rlp. This PR changes that to keep it
in RLP-form as much as possible. When a node is syncing from us, it typically requests 192
contiguous headers. On master it has the following effect:
- For headers not in ancient: 2 db lookups. One for translating hash->number (even though
the request is by number), and another for reading by hash (this latter one is sometimes
cached).
- For headers in ancient: 1 file lookup/syscall for translating hash->number (even though
the request is by number), and another for reading the header itself. After this, it
also performes a hashing of the header, to ensure that the hash is what it expected. In
this PR, I instead move the logic for "give me a sequence of blocks" into the lower
layers, where the database can determine how and what to read from leveldb and/or
ancients.
There are basically four types of requests; three of them are improved this way. The
fourth, by hash going backwards, is more tricky to optimize. However, since we know that
the gap is 0, we can look up by the parentHash, and stlil shave off all the number->hash
lookups.
The gapped collection can be optimized similarly, as a follow-up, at least in three out of
four cases.

This PR fixes a special corner case in transaction indexing.
When the chain is rewound by SetHead to a historical point which is even lower than the transaction indexes tail, then system will report Failed to decode block body error all the time, because the relevant blocks are already deleted.
In order to avoid this "non-critical-but-annoying" issue, we can recap the indexing target to head+1(to is excluded, so it means indexing transactions from 0 to head).

The price limit is supposed to exclude transactions with too low fee
amount. Before EIP-1559, it was sufficient to check the limit against
the gas price of the transaction. After 1559, it is more complicated
because the concept of 'transaction gas price' does not really exist.
When mining, the price limit is used to exclude transactions below a
certain effective fee amount. This change makes it apply the same check
earlier, in tx validation. Transactions below the specified fee amount
cannot enter the pool.
Fixes#23837
This PR offers two more database sub commands for exporting and importing data.
Two exporters are implemented: preimage and snapshot data respectively.
The import command is generic, it can take any data export and import into leveldb.
The data format has a 'magic' for disambiguation, and a version field for future compatibility.
It is because write known block only checks block and state without snapshot, which could lead to gap between newest snapshot and newest block state. However, new blocks which would cause snapshot to become fixed were ignored, since state was already known.

This PR adds a new accessor method to the freezer database. This new view offers a consistent interface, guaranteeing that all individual tables (headers, bodies etc) are all on the same number, and that this number is not changes (added/truncated) while the operation is performing.

This doesn't fix all go-critic warnings, just the most serious ones.

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.
This change removes misuses of sync.WaitGroup in BlockChain. Before this change,
block insertion modified the WaitGroup counter in order to ensure that Stop would wait
for pending operations to complete. This was racy and could even lead to crashes
if Stop was called at an unfortunate time. The issue is resolved by adding a specialized
'closable' mutex, which prevents chain modifications after stopping while also
synchronizing writers with each other.

This resolves a long-standing TODO. The point of copying the address is
to ensure that all data referenced by types.Transaction is independent of the
data passed into the constructor.

This change introduces 2 new optional methods; `enter()` and `exit()` for js tracers, and makes `step()` optiona. The two new methods are invoked when entering and exiting a call frame (but not invoked for the outermost scope, which has it's own methods). Currently these are the data fields passed to each of them:
enter: type (opcode), from, to, input, gas, value
exit: output, gasUsed, error
The PR also comes with a re-write of the callTracer. As a backup we keep the previous tracing script under the name `callTracerLegacy`. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements), where the new tracer is more correct / has more information.
This change is a rewrite of the freezer code.
When writing ancient chain data to the freezer, the previous version first encoded each
individual item to a temporary buffer, then wrote the buffer. For small item sizes (for
example, in the block hash freezer table), this strategy causes a lot of system calls for
writing tiny chunks of data. It also allocated a lot of temporary []byte buffers.
In the new version, we instead encode multiple items into a re-useable batch buffer, which
is then written to the file all at once. This avoids performing a system call for every
inserted item.
To make the internal batching work, the ancient database API had to be changed. While
integrating this new API in BlockChain.InsertReceiptChain, additional optimizations were
also added there.
