Felix Lange	9e5f03b6c4	core/state: access trie through Database interface, track errors (#14589) ... With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).	7 years ago
Felix Lange	4047ccad2f	trie: add start key to NodeIterator constructors ... The 'step' method is split into two parts, 'peek' and 'push'. peek returns the next state but doesn't make it current. The end of iteration was previously tracked by setting 'trie' to nil. End of iteration is now tracked using the 'iteratorEnd' error, which is slightly cleaner and requires less code.	8 years ago
Felix Lange	a13e920af0	trie: clean up iterator constructors ... Make it so each iterator has exactly one public constructor: - NodeIterators can be created through a method. - Iterators can be created through NewIterator on any NodeIterator.	8 years ago
Nick Johnson	555273495b	trie: add difference iterator (#3637) ... This PR implements a differenceIterator, which allows iterating over trie nodes that exist in one trie but not in another. This is a prerequisite for most GC strategies, in order to find obsolete nodes.	8 years ago
