* core, core/state, trie: EIP158, reprice & skip empty account writeJeffrey Wilcke2016-11-137-22/+28
| | | | | | | | | | | | | | | This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke <jeffrey@ethereum.org>

* core/types: remove header accessorsFelix Lange2016-11-094-10/+10
| | | | | | These accessors were introduced by light client changes, but the only method that is actually used is GetNumberU64. This commit replaces all uses of .GetNumberU64 with .Number.Uint64.

* trie, core/state: improve memory usage and performance (#3135)Felix Lange2016-10-151-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* core/state: implement reverts by journaling all changesFelix Lange2016-10-061-9/+5
| | | | | | | | | | This commit replaces the deep-copy based state revert mechanism with a linear complexity journal. This commit also hides several internal StateDB methods to limit the number of ways in which calling code can use the journal incorrectly. As usual consultation and bug fixes to the initial implementation were provided by @karalabe, @obscuren and @Arachnid. Thank you!

* core/state: track all accounts in canon stateFelix Lange2016-09-261-1/+1
| | | | | This change introduces a global, per-state cache that keeps account data in the canon state. Thanks to @karalabe for lots of fixes.
