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 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 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 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
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.
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 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.
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.
* core: use TryGetAccount to read where TryUpdateAccount has been used to write
* Gary's review feedback
* implement Gary's suggestion
* fix bug + rename NewSecure into NewStateTrie
* trie: add backwards-compatibility aliases for SecureTrie
* Update database.go
* make the linter happy

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.
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 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.
