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.

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.

We want to be able to capture StateUpdates even if the Geth snapshot
trie is in a weird state and can't offer the snapshot we're looking
for. This adds our own implementation of the Snapshot() interface
so that we can continue collecting the necessary information to make
it available to the StateUpdates hook.

Notes: the AppendAncient plugin hook is broken by this commit.
This adds CaptureEnter() and CaptureExit() as no-ops for interface
compliance, but these capabilities should be added for plugin tracers
soon.
This makes several updates to support the blockupdates plugin.
I had to update several hooks that were using the wrong types, and
provide a way to get event.Feed objects into plugins without importing
event.Feed (which I did by having the plugin loader make them
available).

The main idea behind it is: the range compaction is very expensive
which can take a few hours to finish. During this long procedure,
a lot of exceptions can occur, e.g.
- Geth is killed manually
- Geth is killed because of machine crash
- etc
In order to minimize the effect of the exceptions, the compaction
is moved out of the pruning. So that even the compaction is not
finished, the pruning is regarded as done.
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.

This commit fixes a flaw in two testcases, and brings down the exec-time from ~40s to ~8s for trie/TestIncompleteSync.
The checkConsistency was performed over and over again on the complete set of nodes, not just the recently added, turning it into a quadratic runtime.
* core/state/snapshot: print warning if failed to resolve journal
* core/state/snapshot: fix snapshot recovery
When we meet the snapshot journal consisted with:
- disk layer generator with new-format
- diff layer journal with old-format
The base layer should be returned without error.
The broken diff layer can be reconstructed later
but we definitely don't want to reconstruct the
huge diff layer.

This change introduces garbage collection for the light client. Historical
chain data is deleted periodically. If you want to disable the GC, use
the --light.nopruning flag.
This PR implements the EVM state transition tool, which is intended
to be the replacement for our retesteth client implementation.

This finally adds the error check that the documentation of StateDB.dbErr
promises to do. dbErr was added in 9e5f03b6c (June 2017), and the check was
already missing in that commit. We somehow survived without it for three years.
