Author	SHA1	Message	Date
Felix Lange	f958d7d482	trie: rework and document key encoding ... 'encode' and 'decode' are meaningless because the code deals with three encodings. Document the encodings and give a name to each one.	8 years ago
Felix Lange	a31d268b76	trie: remove Key in MissingNodeError ... The key was constructed from nibbles, which isn't possible for all nodes. Remove the only use of Key in LightTrie by always retrying with the original key that was looked up.	8 years ago
Nick Johnson	b35aa21f9f	trie: implement unionIterator (#14312)	8 years ago
Péter Szilágyi	09777952ee	core, consensus: pluggable consensus engines (#3817) ... This commit adds pluggable consensus engines to go-ethereum. In short, it introduces a generic consensus interface, and refactors the entire codebase to use this interface.	8 years ago
Felix Lange	f1534f5797	trie, whisper/whisperv5: use math/rand Read function	8 years ago
Péter Szilágyi	d4fd06c3dc	all: blidly swap out glog to our log15, logs need rework	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	b9b3efb09f	all: fix ineffectual assignments and remove uses of crypto.Sha3 ... go get github.com/gordonklaus/ineffassign ineffassign .	8 years ago
Péter Szilágyi	18c77744ff	all: fix spelling errors	8 years ago

Felix Lange	35a7dcb162	all: gofmt -w -s	8 years ago
Felix Lange	d3b751e4d9	trie: remove dependency on ethdb ... This removes the core/types -> leveldb dependency.	8 years ago
Péter Szilágyi	90b16a3e85	core/state, eth/downloader, trie: reset fast-failure on progress	8 years ago
Péter Szilágyi	f8608a5228	trie: while fast syncing, don't keep trie nodes in memory (#3186)	8 years ago
Péter Szilágyi	88a593d559	cmd/geth, trie: report on trie cache unloads, also add debug log	8 years ago
Felix Lange	5d9bb0a050	trie: add metric to track cache unloading (#3175)	8 years ago
Felix Lange	d48e6ae66f	trie: make the cache miss counter a real metric	8 years ago
Péter Szilágyi	2bb5ec1e41	cmd/geth, trie: track and report trie cache misses	8 years ago
Felix Lange	8d56bf5ceb	trie: ensure dirty flag is unset for embedded child nodes ... This was caught by the new invariant check.	8 years ago
Felix Lange	177cab5fe7	trie: ensure resolved nodes stay loaded ... Commit 40cdcf1183 broke the optimisation which kept nodes resolved during Get in the trie. The decoder assigned cache generation 0 unconditionally, causing resolved nodes to get flushed on Commit. This commit fixes it and adds two tests.	8 years ago
Felix Lange	187d6a66a5	trie: avoid loading the root node twice ... New checks whether the root node is present by loading it from the database. Keep the node around instead of discarding it.	8 years ago
Felix Lange	2cd7a0395d	trie: fix regression that linked all downloaded nodes together ... The trie sync code links subtries using pointers into node structs. Since commit 40cdcf1183 nodes are no longer copied when unpacking from an interface value, causing all nodes to get linked up as the sync progresses. Fix it by breaking the pointer chain with an explicit copy.	8 years ago
Felix Lange	40cdcf1183	trie, core/state: improve memory usage and performance (#3135) ... * trie: store nodes as pointers This avoids memory copies when unwrapping node interface values. name old time/op new time/op delta Get 388ns ± 8% 215ns ± 2% -44.56% (p=0.000 n=15+15) GetDB 363ns ± 3% 202ns ± 2% -44.21% (p=0.000 n=15+15) UpdateBE 1.57µs ± 2% 1.29µs ± 3% -17.80% (p=0.000 n=13+15) UpdateLE 1.92µs ± 2% 1.61µs ± 2% -16.25% (p=0.000 n=14+14) HashBE 2.16µs ± 6% 2.18µs ± 6% ~ (p=0.436 n=15+15) HashLE 7.43µs ± 3% 7.21µs ± 3% -2.96% (p=0.000 n=15+13) * trie: close temporary databases in GetDB benchmark * trie: don't keep []byte from DB load around Nodes decoded from a DB load kept hashes and values as sub-slices of the DB value. This can be a problem because loading from leveldb often returns []byte with a cap that's larger than necessary, increasing memory usage. * trie: unload old cached nodes * trie, core/state: use cache unloading for account trie * trie: use explicit private flags (fixes Go 1.5 reflection issue). * trie: fixup cachegen overflow at request of nick * core/state: rename journal size constant	8 years ago
Felix Lange	c3a77d6268	trie: fix delete bug for values contained in fullNode ... Delete crashed if a fullNode contained a valueNode directly. This bug is very unlikely to occur with SecureTrie, but can happen with regular tries. This commit also introduces a randomised test which triggers all trie operations, which should prevent such bugs in the future. Credit for finding this bug goes to Github user @rjl493456442.	8 years ago
Felix Lange	ba8c4c6b1a	trie: remove dependency on package crypto ... Package crypto needs cgo, which is inconvenient for some build configurations.	8 years ago

Jeffrey Wilcke	b8ca0a830e	eth, trie: removed key prefixing from state entries & merge db fix ... Fixed database merge strategy to use the correct database. Due to a copy paste fail when doing type evaluation the same database was being iterated (chain), all others were ignored. Removed state prefixing because {H(code): code} is stored in the same database as the rest of the state.	9 years ago
Jeffrey Wilcke	a23478c0be	core, eth, trie, xeth: merged state, chain, extra databases in one	9 years ago
Ethan Buchman	46c9594081	trie: run codec tests, add benchmarks, faster	9 years ago
