rjl493456442	bc1ec69008	trie/pathdb: state iterator (snapshot integration pt 4) (#30654) ... In this pull request, the state iterator is implemented. It's mostly a copy-paste from the original state snapshot package, but still has some important changes to highlight here: (a) The iterator for the disk layer consists of a diff iterator and a disk iterator. Originally, the disk layer in the state snapshot was a wrapper around the disk, and its corresponding iterator was also a wrapper around the disk iterator. However, due to structural differences, the disk layer iterator is divided into two parts: - The disk iterator, which traverses the content stored on disk. - The diff iterator, which traverses the aggregated state buffer. Checkout `BinaryIterator` and `FastIterator` for more details. (b) The staleness management is improved in the diffAccountIterator and diffStorageIterator Originally, in the `diffAccountIterator`, the layer’s staleness had to be checked within the Next function to ensure the iterator remained usable. Additionally, a read lock on the associated diff layer was required to first retrieve the account blob. This read lock protection is essential to prevent concurrent map read/write. Afterward, a staleness check was performed to ensure the retrieved data was not outdated. The entire logic can be simplified as follows: a loadAccount callback is provided to retrieve account data. If the corresponding state is immutable (e.g., diff layers in the path database), the staleness check can be skipped, and a single account data retrieval is sufficient. However, if the corresponding state is mutable (e.g., the disk layer in the path database), the callback can operate as follows: ```go func(hash common.Hash) ([]byte, error) { dl.lock.RLock() defer dl.lock.RUnlock() if dl.stale { return nil, errSnapshotStale } return dl.buffer.states.mustAccount(hash) } ``` The callback solution can eliminate the complexity for managing concurrency with the read lock for atomic operation.	2 months ago
rjl493456442	05148d972c	triedb/pathdb: track flat state changes in pathdb (snapshot integration pt 2) (#30643) ... This pull request ports some changes from the main state snapshot integration one, specifically introducing the flat state tracking in pathdb. Note, the tracked flat state changes are only held in memory and won't be persisted in the disk. Meanwhile, the correspoding state retrieval in persistent state is also not supported yet. The states management in disk is more complicated and will be implemented in a separate pull request. Part 1: https://github.com/ethereum/go-ethereum/pull/30752	3 months ago
