For many uses of HasHeader, the expectation is that it's actually there. Using Has avoids a load + decode of the value. * core: write fast sync block data in batches Collect writes into batches up to the ideal size instead of issuing many small, concurrent writes. * eth/downloader: commit larger state batches Collect nodes into a batch up to the ideal size instead of committing whenever a node is received. * core: optimize HasBlock check This avoids a random database read to get the number. * core: use numberCache in HasHeader numberCache has higher capacity, increasing the odds of finding the header without a database lookup. * core: write imported block data using a batch Restore batch writes of state and add blocks, tx entries, receipts to the same batch. The change also simplifies the miner. This commit also removes posting of logs when a forked block is imported. * core: fix DB write error handling * ethdb: use RLock for Has * core: fix HasBlock comment

* core/state: access trie through Database interface, track errors (#14589)Felix Lange2017-06-271-1/+1
| | | | | | | | | With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).

* core, consensus: pluggable consensus engines (#3817)Péter Szilágyi2017-04-051-41/+52
| | | | | This commit adds pluggable consensus engines to go-ethereum. In short, it introduces a generic consensus interface, and refactors the entire codebase to use this interface.
* all: import "context" instead of "golang.org/x/net/context"Felix Lange2017-03-231-1/+1
| | | | | | | | | | There is no need to depend on the old context package now that the minimum Go version is 1.7. The move to "context" eliminates our weird vendoring setup. Some vendored code still uses golang.org/x/net/context and it is now vendored in the normal way. This change triggered new vet checks around context.WithTimeout which didn't fire with golang.org/x/net/context.

* core/vm: improved EVM run loop & instruction calling (#3378)Jeffrey Wilcke2017-01-051-2/+2
| | | | | | | | | | | | | | | The run loop, which previously contained custom opcode executes have been removed and has been simplified to a few checks. Each operation consists of 4 elements: execution function, gas cost function, stack validation function and memory size function. The execution function implements the operation's runtime behaviour, the gas cost function implements the operation gas costs function and greatly depends on the memory and stack, the stack validation function validates the stack and makes sure that enough items can be popped off and pushed on and the memory size function calculates the memory required for the operation and returns it. This commit also allows the EVM to go unmetered. This is helpful for offline operations such as contract calls.

| | | | | | | | 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.

| | | | | | | | | | | | | | | 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>
* Godeps, vendor: convert dependency management to trash (#3198)Péter Szilágyi2016-10-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | This commit converts the dependency management from Godeps to the vendor folder, also switching the tool from godep to trash. Since the upstream tool lacks a few features proposed via a few PRs, until those PRs are merged in (if), use github.com/karalabe/trash. You can update dependencies via trash --update. All dependencies have been updated to their latest version. Parts of the build system are reworked to drop old notions of Godeps and invocation of the go vet command so that it doesn't run against the vendor folder, as that will just blow up during vetting. The conversion drops OpenCL (and hence GPU mining support) from ethash and our codebase. The short reasoning is that there's noone to maintain and having opencl libs in our deps messes up builds as go install ./... tries to build them, failing with unsatisfied link errors for the C OpenCL deps. golang.org/x/net/context is not vendored in. We expect it to be fetched by the user (i.e. using go get). To keep ci.go builds reproducible the package is "vendored" in build/_vendor.

* core/vm: Refactor tracing to make Tracer the main interfaceNick Johnson2016-08-221-34/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * core/state, eth: Updated suicides objects when tracing transactionsJeffrey Wilcke2016-06-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
