Péter Szilágyi	55599ee95d	core, trie: intermediate mempool between trie and database (#15857) ... This commit reduces database I/O by not writing every state trie to disk.	7 years ago
Felix Lange	693d9ccbfb	trie: more node iterator improvements (#14615) ... * ethdb: remove Set Set deadlocks immediately and isn't part of the Database interface. * trie: add Err to Iterator This is useful for testing because the underlying NodeIterator doesn't need to be kept in a separate variable just to get the error. * trie: add LeafKey to iterator, panic when not at leaf LeafKey is useful for callers that can't interpret Path. * trie: retry failed seek/peek in iterator Next Instead of failing iteration irrecoverably, make it so Next retries the pending seek or peek every time. Smaller changes in this commit make this easier to test: * The iterator previously returned from Next on encountering a hash node. This caused it to visit the same path twice. * Path returned nibbles with terminator symbol for valueNode attached to fullNode, but removed it for valueNode attached to shortNode. Now the terminator is always present. This makes Path unique to each node and simplifies Leaf. * trie: add Path to MissingNodeError The light client trie iterator needs to know the path of the node that's missing so it can retrieve a proof for it. NodeIterator.Path is not sufficient because it is updated when the node is resolved and actually visited by the iterator. Also remove unused fields. They were added a long time ago before we knew which fields would be needed for the light client.	8 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	b35aa21f9f	trie: implement unionIterator (#14312)	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

Felix Lange	bfbcfbe4a9	all: fix license headers one more time ... I forgot to update one instance of "go-ethereum" in commit 3f047be5a.	9 years ago
Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL ... All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago
