* core/vm: Refactor tracing to make Tracer the main interfaceNick Johnson2016-08-2212-176/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | This CL makes several refactors: - Define a Tracer interface, implementing the `CaptureState` method - Add the VM environment as the first argument of `Tracer.CaptureState` - Rename existing functionality `StructLogger` an make it an implementation of `Tracer` - Delete `StructLogCollector` and make `StructLogger` collect the logs directly - Change all callers to use the new `StructLogger` where necessary and extract logs from that. - Deletes the apparently obsolete and likely nonfunctional 'TraceCall' from the eth API. Callers that only wish accumulated logs can use the `StructLogger` implementation straightforwardly. Callers that wish to efficiently capture VM traces and operate on them without excessive copying can now implement the `Tracer` interface to receive VM state at each step and do with it as they wish. This CL also removes the accumulation of logs from the vm.Environment; this was necessary as part of the refactor, but also simplifies it by removing a responsibility that doesn't directly belong to the Environment.

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 transactions
| * 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

* eth: enable bad block reportsFelix Lange2016-05-253-78/+5
| | | | | | | | | | | | We used to have reporting of bad blocks, but it was disabled before the Frontier release. We need it back because users are usually unable to provide the full RLP data of a bad block when it occurs. A shortcoming of this particular implementation is that the origin peer is not tracked for blocks received during eth/63 sync. No origin peer info is still better than no report at all though.

* core, eth, miner: improve shutdown synchronisationFelix Lange2016-05-091-4/+7
| | | | | | | | | | | | | | | | | | | | Shutting down geth prints hundreds of annoying error messages in some cases. The errors appear because the Stop method of eth.ProtocolManager, miner.Miner and core.TxPool is asynchronous. Left over peer sessions generate events which are processed after Stop even though the database has already been closed. The fix is to make Stop synchronous using sync.WaitGroup. For eth.ProtocolManager, in order to make use of WaitGroup safe, we need a way to stop new peer sessions from being added while waiting on the WaitGroup. The eth protocol Run function now selects on a signaling channel and adds to the WaitGroup only if ProtocolManager is not shutting down. For miner.worker and core.TxPool the number of goroutines is static, WaitGroup can be used in the usual way without additional synchronisation.
* core: Provide a public accessor for ChainConfigNicholas Johnson2016-04-291-0/+3
| | | | This is necessary for external users of the go-ethereum code who want to, for instance, build a custom node that plays back transactions, as core.ApplyTransaction requires a ChainConfig as a parameter.
* core, eth: added json tag field for proper unmarshallingJeffrey Wilcke2016-04-251-1/+1
| | | | | | | | | According to our own instructions the genesis config attribute should be "config". The genesis definition in the go code, however, has a field called `ChainConfig`. This field now has a `json:"config"` struct tag so that the json is properly unmarshalled. This fixes #2482

* 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: 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`.

| | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | 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.
