* all: blidly swap out glog to our log15, logs need reworkPéter Szilágyi2017-02-231-8/+7

* trie: remove dependency on ethdbFelix Lange2017-01-061-1/+5
| | | | This removes the core/types -> leveldb dependency.

|\ | | | | trie: improve cache unloading mechanism
| * trie: ensure resolved nodes stay loadedFelix Lange2016-10-181-4/+7
| | | | | | | | | | | | | | | | 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: avoid loading the root node twiceFelix Lange2016-10-181-6/+4
| | | | | | | | | | New checks whether the root node is present by loading it from the database. Keep the node around instead of discarding it.

* trie, core/state: improve memory usage and performance (#3135)Felix Lange2016-10-151-57/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 Lange2016-09-301-0/+3
| | | | | | | | | 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.
* trie: remove dependency on package cryptoFelix Lange2016-09-301-3/+6
| | | | | Package crypto needs cgo, which is inconvenient for some build configurations.

* all: Rename crypto.Sha3{,Hash}() to crypto.Keccak256{,Hash}()Ricardo Catalinas Jiménez2016-02-221-1/+1
| | | | As we aren't really using the standarized SHA-3

* trie: added error handlingzsfelfoldi2015-12-011-58/+146
| | | | Created alternate versions of Trie and SecureTrie functions that can return a MissingNodeError (used by ODR services)

* eth, trie: removed key prefixing from state entries & merge db fixJeffrey Wilcke2015-08-141-2/+0
| | | | | | | | | 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.
* core, eth, trie, xeth: merged state, chain, extra databases in oneJeffrey Wilcke2015-08-081-0/+2

| | | | I forgot to update one instance of "go-ethereum" in commit 3f047be5a.
* all: update license headers to distiguish GPL/LGPLFelix Lange2015-07-231-4/+4
| | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".
