* core, trie: intermediate mempool between trie and database (#15857)Péter Szilágyi2018-02-061-3/+2
| | | This commit reduces database I/O by not writing every state trie to disk.
* core/state: access trie through Database interface, track errors (#14589)Felix Lange2017-06-271-22/+34
| | | | | | | | | With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).

* core/state: make TestSnapshotRandom work again (#3816)gary rong2017-04-051-2/+3
| | | | | | In `touch` operation, only `touched` filed has been changed. Therefore in the related undo function, only `touched` field should be reverted. In addition, whether remove this obj from dirty map should depend on prevDirty flag.

This commit replaces them all with Int.Sign, which is cheaper and less code. eg templates: func before(x *big.Int) bool { return x.BitLen() == 0 } func after(x *big.Int) bool { return x.Sign() == 0 } func before(x *big.Int) bool { return x.BitLen() > 0 } func after(x *big.Int) bool { return x.Sign() != 0 } func before(x *big.Int) int { return x.Cmp(common.Big0) } func after(x *big.Int) int { return x.Sign() } * common/math, crypto/secp256k1: make ReadBits public in package math

* core, core/state, core/vm: remove exported account getters (#3618)Jeffrey Wilcke2017-02-231-50/+34
| | | | Removed exported statedb object accessors, reducing the chance for nasty bugs to creep in. It's also ugly and unnecessary to have these methods.
* logger: remove Core verbosity level (#3659)Felix Lange2017-02-151-3/+3
|
* core, core/vm: implemented a generic environment (#3348)Jeffrey Wilcke2016-12-061-1/+1
| | | | | | | | Environment is now a struct (not an interface). This reduces a lot of tech-debt throughout the codebase where a virtual machine environment had to be implemented in order to test or run it. The new environment is suitable to be used en the json tests, core consensus and light client.
* core, core/state: fixed consensus issue added touch revertJeffrey Wilcke2016-11-251-1/+18
| | | | | Implemented proper touch revert journal entries and copied a Parity consensus bug in order to remain in sync with the current longest chain.
* core, core/state, trie: EIP158, reprice & skip empty account writeJeffrey Wilcke2016-11-131-1/+12
| | | | | | | | | | | | | | | 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>
* trie, core/state: improve memory usage and performance (#3135)Felix Lange2016-10-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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: optimize GetStateFelix Lange2016-10-061-5/+7
| | | | There is no need to use the reflection-based decoder to decode []byte.
* core/state: rename Delete/IsDeleted to Suicide/HasSuicidedFelix Lange2016-10-061-6/+6
| | | | The delete/remove naming has caused endless confusion in the past.
* core/state: implement reverts by journaling all changesFelix Lange2016-10-061-9/+45
| | | | | | | | | | 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, core/state: move gas tracking out of core/stateFelix Lange2015-10-171-36/+1
| | | | | | | The amount of gas available for tx execution was tracked in the StateObject representing the coinbase account. This commit makes the gas counter a separate type in package core, which avoids unintended consequences of intertwining the counter with state logic.
