This pull request tracks the state indexing progress in eth_syncing
RPC response, i.e. we will return non-null syncing status until indexing
has finished.
This pull request fixes a flaw in PBSS archive mode that significantly
degrades performance when the mode is enabled.
Originally, in hash mode, the dirty trie cache is completely disabled
when archive mode is active, in order to disable the in-memory garbage
collection mechanism. However, the internal logic in path mode differs
significantly, and the dirty trie node cache is essential for maintaining
chain insertion performance. Therefore, the cache is now retained in
path mode.
