* core: transition db now also returns the required gas amountJeffrey Wilcke2016-04-011-7/+24
| | | | | | | | | Exposes some core methods to transition and compute new state information and adds an additional return value to the transition db method to fetch required gas for that particular message (excluding gas refunds from any SSTORE[X] = 0 and SUICIDE. Fixes #2395
* accounts/a/b/backends, core: chain maker homestead block set to 0Jeffrey Wilcke2016-04-014-24/+12
| | | | | | | 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 Wilcke2016-04-0131-159/+295
| | | | | | | | | 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, eth, cmd: temporary work around for enabling the jitJeffrey Wilcke2016-03-241-1/+6
| | | | | This commit serves as a temporary workaround for enabling the jit until the block customisation PR is merged in.
* core: Added EVM configuration optionsJeffrey Wilcke2016-03-2420-194/+385
| | | | | The EVM is now initialised with an additional configured object that allows you to turn on debugging options.
* core, core/vm, tests: changed the initialisation behaviour of the EVMJeffrey Wilcke2016-03-2311-42/+34
| | | | | | | The EVM was previously initialised and created for every CALL, CALLCODE, DELEGATECALL and CREATE. This PR changes this behaviour so that the same EVM can be used through the session and beyond as long as the Environment sticks around.

This fixes a nil pointer in the range loop when trying to retrieve a block from the set which was previously available but removed due to regular chain processing. Fixes #2305

| | | | | | | | | | | | | | | | | | | | | | Previously all blocks that were already in our chain were never re announced as potential uncle block (e.g. ChainSideEvent). This is problematic during mining where you want to gather as much possible uncles as possible increasing the profit. This is now addressed in this PR where during reorganisations of chains the old chain is regarded as uncles. Fixed #2298

* | core: Added new TD strategy which mitigate the risk for selfish miningJeffrey Wilcke2016-02-181-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assuming the following scenario where a miner has 15% of all hashing power and the ability to exert a moderate control over the network to the point where if the attacker sees a message A, it can't stop A from propagating, but what it **can** do is send a message B and ensure that most nodes see B before A. The attacker can then selfish mine and augment selfish mining strategy by giving his own blocks an advantage. This change makes the time at which a block is received less relevant and so the level of control an attacker has over the network no longer makes a difference. This change changes the current td algorithm `B_td > C_td` to the new algorithm `B_td > C_td || B_td == C_td && rnd < 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, eth, rpc: split out block validator and state processorJeffrey Wilcke2015-11-1812-599/+646
| | | | | | | | | | | | | | | | | | | | | | | | 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).
