Felix Lange	f2da6581ba	all: fix issues reported by honnef.co/go/simple/cmd/gosimple	8 years ago
Felix Lange	35a7dcb162	all: gofmt -w -s	8 years ago
Felix Lange	d3b751e4d9	trie: remove dependency on ethdb ... This removes the core/types -> leveldb dependency.	8 years ago
Felix Lange	7731061903	core/vm: move Log to core/types ... 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.	8 years ago
Jeffrey Wilcke	3fc7c97827	core, core/vm: implemented a generic environment (#3348) ... 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.	8 years ago
Jeffrey Wilcke	12d654a6fc	core, core/state: fixed consensus issue added touch revert ... Implemented proper touch revert journal entries and copied a Parity consensus bug in order to remain in sync with the current longest chain.	8 years ago
Jeffrey Wilcke	aad4890082	cmd/geth, core, light, mobile: removed state account StartingNonce ... All account's nonce start at 0.	8 years ago
Jeffrey Wilcke	445feaeef5	core, core/state, trie: EIP158, reprice & skip empty account write ... 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>	8 years ago

Péter Szilágyi	88a593d559	cmd/geth, trie: report on trie cache unloads, also add debug log	8 years ago
Péter Szilágyi	4f46bd19d0	cmd, core/state: allow configurable trie cache generations	8 years ago
Felix Lange	44f419ec0f	core/state: bump trie cache values slightly	8 years ago
Felix Lange	40cdcf1183	trie, core/state: improve memory usage and performance (#3135) ... * 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	8 years ago
Felix Lange	3c836dd71b	core/state: optimize GetState ... There is no need to use the reflection-based decoder to decode []byte.	8 years ago
Felix Lange	90fce8bfa6	core/state: rename Delete/IsDeleted to Suicide/HasSuicided ... The delete/remove naming has caused endless confusion in the past.	8 years ago
Felix Lange	1f1ea18b54	core/state: implement reverts by journaling all changes ... 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!	8 years ago
Péter Szilágyi	b7159818f9	core/state: track dirty state entries for each object	8 years ago
Péter Szilágyi	cb84e3f029	cmd, core, internal, light, tests: avoid hashing the code in the VM	8 years ago
Péter Szilágyi	710435b51b	core, eth, trie: reuse trie journals in all our code	8 years ago
Felix Lange	cd791bd855	core, trie: replace state caches with trie journal	8 years ago
Felix Lange	a59a93f476	core/state: track all accounts in canon state ... This change introduces a global, per-state cache that keeps account data in the canon state. Thanks to @karalabe for lots of fixes.	8 years ago

Péter Szilágyi	ba784bdf36	core: update DAO soft-fork number, clean up the code	9 years ago
Jeffrey Wilcke	7a5b571c67	test, cmd/evm, core, core/vm: illegal code hash implementation ... 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.	9 years ago
Jeffrey Wilcke	bb3651abc8	core/state, eth: Updated suicides objects when tracing transactions ... 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.
