Péter Szilágyi	9b84caf3a5	core, eth, les: support resuming fast sync on heavy rollback (#3743)	8 years ago
Jeffrey Wilcke	c12f4df910	params: core, core/vm, miner: 64bit gas instructions ... Reworked the EVM gas instructions to use 64bit integers rather than arbitrary size big ints. All gas operations, be it additions, multiplications or divisions, are checked and guarded against 64 bit integer overflows. In additon, most of the protocol paramaters in the params package have been converted to uint64 and are now constants rather than variables. * common/math: added overflow check ops * core: vmenv, env renamed to evm * eth, internal/ethapi, les: unmetered eth_call and cancel methods * core/vm: implemented big.Int pool for evm instructions * core/vm: unexported intPool methods & verification methods * core/vm: added memoryGasCost overflow check and test	8 years ago
Jeffrey Wilcke	57f4e90257	Revert "params: core, core/vm, miner: 64bit gas instructions (#3514)" ... This reverts commit 8b57c49490.	8 years ago

Jeffrey Wilcke	4dca5d4db7	core/types, params: EIP#155	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

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

Péter Szilágyi	1f39746886	eth/downloader: throttling tests are time-sensitive, don't run parallel	9 years ago
Felix Lange	9be5d5cd90	eth/downloader: fix negative balance issue in tests ... The test chain generated by makeChainFork included invalid uncle headers, crashing the generator during the state commit. The headers were invalid because they used the iteration counter as the block number, even though makeChainFork uses a block with number > 0 as the parent. Fix this by introducing BlockGen.Number, which allows accessing the actual number of the block being generated.	9 years ago
Felix Lange	dd09af27af	eth/downloader: run tests in parallel	9 years ago
Felix Lange	900da3d800	eth/downloader: don't hang for spurious deliveries ... Unexpected deliveries could block indefinitely if they arrived at the right time. The fix is to ensure that the cancellation channel is always closed when the sync ends, unblocking any deliveries. Also remove the atomic check for whether a sync is currently running because it doesn't help and can be misleading. Cancelling always seems to break the tests though. The downloader spawned d.process whenever new data arrived, making it somewhat hard to track when block processing was actually done. Fix this by running d.process in a dedicated goroutine that is tied to the lifecycle of the sync. d.process gets notified of new work by the queue instead of being invoked all the time. This removes a ton of weird workaround code, including a hairy use of atomic CAS.	9 years ago
