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	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	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	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
