* trie: ensure dirty flag is unset for embedded child nodesFelix Lange2016-10-181-15/+28
| | | | This was caught by the new invariant check.
* trie: ensure resolved nodes stay loadedFelix Lange2016-10-181-21/+70
| | | | | | | | 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.
* trie, core/state: improve memory usage and performance (#3135)Felix Lange2016-10-151-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* trie: fix delete bug for values contained in fullNodeFelix Lange2016-09-301-35/+124
| | | | | | | | | 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.

| | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".
