This change addresses an issue in snap sync, specifically when the entire sync process can be halted due to an encountered empty storage range.
Currently, on the snap sync client side, the response to an empty (partial) storage range is discarded as a non-delivery. However, this response can be a valid response, when the particular range requested does not contain any slots.
For instance, consider a large contract where the entire key space is divided into 16 chunks, and there are no available slots in the last chunk [0xf] -> [end]. When the node receives a request for this particular range, the response includes:
The proof with origin [0xf]
A nil storage slot set
If we simply discard this response, the finalization of the last range will be skipped, halting the entire sync process indefinitely. The test case TestSyncWithUnevenStorage can reproduce the scenario described above.
In addition, this change also defines the common variables MaxAddress and MaxHash.
This change
- Removes the owner-notion from a stacktrie; the owner is only ever needed for comitting to the database, but the commit-function, the `writeFn` is provided by the caller, so the caller can just set the owner into the `writeFn` instead of having it passed through the stacktrie.
- Removes the `encoding.BinaryMarshaler`/`encoding.BinaryUnmarshaler` interface from stacktrie. We're not using it, and it is doubtful whether anyone downstream is either.
This is a minor refactor in preparation of changes to range verifier. This PR contains no intentional functional changes but moves (and renames) the light.NodeSet
This change refactors stacktrie to separate the stacktrie itself from the
internal representation of nodes: a stacktrie is not a recursive structure
of stacktries, rather, a framework for representing and operating upon a set of nodes.

This change fixes the bug in a benchmark, where the input to the trie is reused in a way which is not correct.

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.
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.
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.
* trie: add node type common package
In trie/types package, a few node wrappers are defined, which will be used
in both trie package, trie/snap package, etc. Therefore, a standalone common
package is created to put these stuffs.
* trie: rename trie/types to trie/trienode
In this PR, all TryXXX(e.g. TryGet) APIs of trie are renamed to XXX(e.g. Get) with an error returned.
The original XXX(e.g. Get) APIs are renamed to MustXXX(e.g. MustGet) and does not return any error -- they print a log output. A future PR will change the behaviour to panic on errorrs.
This change renames StateTrie methods to remove the Try* prefix.
We added the Trie methods with prefix 'Try' a long time ago, working
around the problem that most existing methods of Trie did not return the
database error. This weird naming convention has persisted until now.

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 EmptyRootHash and EmptyCodeHash are defined everywhere in the codebase, this PR replaces all of them with unified one defined in core/types package, and also defines constants for TxRoot, WithdrawalsRoot and UncleRoot
This PR contains a small portion of the full pbss PR, namely
Remove the tracer from trie (and comitter), and instead using an accessList.

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 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 fixes an error in trie commit. If the trie.root is nil, it can be two possible scenarios:
- The trie was empty, and no change happens
- The trie was non-empty and all nodes are dropped
For the latter one, we should collect the deletions and apply them into database(e.g. in PBSS).
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 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
This avoids copying the input []byte while decoding trie nodes. In most
cases, particularly when the input slice is provided by the underlying
database, this optimization is safe to use.
For cases where the origin of the input slice is unclear, the copying version
is retained. The new code performs better even when the input must be
copied, because it is now only copied once in decodeNode.
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 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 includes minor updates to comments in trie/committer that reference insertion to the db, and adds an err != nil check for the return value of preimages.commit.
It's a trivial PR to hide the error log when the trie node is not found in the database. The idea for this change is for all TryXXX functions, the error is already returned and we don't need to fire a log explicitly.
Recently there are a few tickets #25613#25589 reporting that the trie nodes are missing because of debug.SetHead. The root cause is after resetting, the chain rewinds to a historical point and re-imports the blocks on top.
Since the node is already synced and started to accept transactions previously, these transactions are still kept in the txpool and verified by txpool with a live state. This live state is constructed based on the live trie database, which is changed fast by node referencing and de-referencing.
Unfortunately, when we construct a live state(like the state in txpool), we don't reference the state we have. The blockchain will garbage collect the intermediate version nodes in another thread which leads the broken live state.
The best solution for this is to forcibly obtain a reference for all live states we create and call release function once it's used up. But it might end up with more junks persisted into disk. Will try to find an elegant solution later in the following PR.
This change speeds up trie hashing and all other activities that require
RLP encoding of trie nodes by approximately 20%. The speedup is achieved by
avoiding reflection overhead during node encoding.
The interface type trie.node now contains a method 'encode' that works with
rlp.EncoderBuffer. Management of EncoderBuffers is left to calling code.
trie.hasher, which is pooled to avoid allocations, now maintains an
EncoderBuffer. This means memory resources related to trie node encoding
are tied to the hasher pool.

* trie: fix memory leak in trie iterator
In the trie iterator, live nodes are tracked in a stack while iterating.
Popped node states should be explictly set to nil in order to get
garbage-collected.
* trie: fix empty trie iterator
This avoids copying the input []byte while decoding trie nodes. In most
cases, particularly when the input slice is provided by the underlying
database, this optimization is safe to use.
For cases where the origin of the input slice is unclear, the copying version
is retained. The new code performs better even when the input must be
copied, because it is now only copied once in decodeNode.

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.
