* core, core/state, trie: EIP158, reprice & skip empty account writeJeffrey Wilcke2016-11-131-10/+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>
* core/state: implement reverts by journaling all changesFelix Lange2016-10-061-1/+1
| | | | | | | | | | 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!
* accounts, core, eth: pass chain config for chain maker to test DAOPéter Szilágyi2016-07-151-3/+25

* accounts/a/b/backends, core: chain maker homestead block set to 0Jeffrey Wilcke2016-04-011-15/+6
| | | | | | | The chain maker and the simulated backend now run with a homestead phase beginning at block 0 (i.e. there's no frontier). This commit also fixes up #2388
* core: added basic chain configurationJeffrey Wilcke2016-04-011-4/+23
| | | | | | | | | Added chain configuration options and write out during genesis database insertion. If no "config" was found, nothing is written to the database. Configurations are written on a per genesis base. This means that any chain (which is identified by it's genesis hash) can have their own chain settings.
* core: Added EVM configuration optionsJeffrey Wilcke2016-03-241-1/+1
| | | | | The EVM is now initialised with an additional configured object that allows you to turn on debugging options.

|
* eth/downloader: fix negative balance issue in testsFelix Lange2015-12-181-0/+5
| | | | | | | | | | 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.
* core: added a new RemovedLogEventJeffrey Wilcke2015-12-011-2/+2
| | | | | | When a chain reorganisation occurs we collect the logs that were deleted during the chain reorganisation. The removed logs are posted to the event mux indicating that those were deleted during the reorg.
* cmd, common, core, eth, node, rpc, tests, whisper, xeth: use protocol stacksPéter Szilágyi2015-11-271-1/+1

* core, eth, rpc: split out block validator and state processorJeffrey Wilcke2015-11-181-7/+4
| | | | | | | | | | | | This removes the burden on a single object to take care of all validation and state processing. Now instead the validation is done by the `core.BlockValidator` (`types.Validator`) that takes care of both header and uncle validation through the `ValidateBlock` method and state validation through the `ValidateState` method. The state processing is done by a new object `core.StateProcessor` (`types.Processor`) and accepts a new state as input and uses that to process the given block's transactions (and uncles for rewords) to calculate the state root for the next block (P_n + 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.

| * core, eth/filters, miner, xeth: Optimised log filteringJeffrey Wilcke2015-10-171-1/+6
| | | | | | | | | | | | | | Log filtering is now using a MIPmap like approach where addresses of logs are added to a mapped bloom bin. The current levels for the MIP are in ranges of 1.000.000, 500.000, 100.000, 50.000, 1.000. Logs are therefor filtered in batches of 1.000.

| | | | | | | | | | | | * Update => SyncIntermediate * Added SyncObjects SyncIntermediate only updates whatever has changed, but, as a side effect, requires much more disk space. SyncObjects will only sync whatever is required for a block and will not save intermediate state to disk. As drawback this requires more time when more txs come in.
