* state: take write lock in GetNonce (#3625)Brian Schroeder2017-02-011-3/+5
| | | | We must take a write lock here because `GetNonce` calls `StateDB.GetStateObject`, which mutates the DB's live set.
* cmd/geth, core: add support for recording SHA3 preimages (#3543)Nick Johnson2017-01-172-1/+32

* trie: remove dependency on ethdbFelix Lange2017-01-062-9/+8
| | | | This removes the core/types -> leveldb dependency.
* core/vm: move Log to core/typesFelix Lange2017-01-062-12/+13
| | | | | | | | This significantly reduces the dependency closure of ethclient, which no longer depends on core/vm as of this change. All uses of vm.Logs are replaced by []*types.Log. NewLog is gone too, the constructor simply returned a literal.
* core, core/vm: implemented a generic environment (#3348)Jeffrey Wilcke2016-12-062-1/+10
| | | | | | | | 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 Wilcke2016-11-253-2/+51
| | | | | Implemented proper touch revert journal entries and copied a Parity consensus bug in order to remain in sync with the current longest chain.
* cmd/geth, core, light, mobile: removed state account StartingNonceJeffrey Wilcke2016-11-231-6/+2
| | | | All account's nonce start at 0.
* core, core/state, trie: EIP158, reprice & skip empty account writeJeffrey Wilcke2016-11-135-18/+38
| | | | | | | | | | | | | | | 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: 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 Lange2016-10-065-27/+27
| | | | The delete/remove naming has caused endless confusion in the past.
* core/state: implement reverts by journaling all changesFelix Lange2016-10-068-143/+584
| | | | | | | | | | 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!

|
* test, cmd/evm, core, core/vm: illegal code hash implementationJeffrey Wilcke2016-06-221-0/+10
| | | | | | | | This implements a generic approach to enabling soft forks by allowing anyone to put in hashes of contracts that should not be interacted from. This will help "The DAO" in their endevour to stop any whithdrawals from any DAO contract by convincing the mining community to accept their code hash.
* core/state, eth: Updated suicides objects when tracing transactionsJeffrey Wilcke2016-06-131-0/+21
| | | | | | | | | | | | | | | | | | | | | | Consensus rules dictate that objects can only be removed during the finalisation of the transaction (i.e. after all calls have finished). Thus calling a suicided contract twice from the same transaction: A->B(S)->ret(A)->B(S) results in 2 suicides. Calling the suicided object twice from two transactions: A->B(S), A->B, results in only one suicide and a call to an empty object. Our current debug tracing functionality replays all transaction that were executed prior to the targetted transaction in order to provide the user with an accurate trace. As a side effect to calling StateDB.IntermediateRoot it also deletes any suicides objects. Our tracing code never calls this function because it isn't interested in the intermediate root. Becasue of this it caused a bug in the tracing code where transactions that were send to priviously deleted objects resulted in two suicides rather than one suicide and a call to an empty object. Fixes #2542
