* consensus/ethash: improve cache/dataset handling (#15864)Felix Lange2018-01-238-213/+208
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * consensus/ethash: add maxEpoch constant * consensus/ethash: improve cache/dataset handling There are two fixes in this commit: Unmap the memory through a finalizer like the libethash wrapper did. The release logic was incorrect and freed the memory while it was being used, leading to crashes like in #14495 or #14943. Track caches and datasets using simplelru instead of reinventing LRU logic. This should make it easier to see whether it's correct. * consensus/ethash: restore 'future item' logic in lru * consensus/ethash: use mmap even in test mode This makes it possible to shorten the time taken for TestCacheFileEvict. * consensus/ethash: shuffle func calc*Size comments around * consensus/ethash: ensure future cache/dataset is in the lru cache * consensus/ethash: add issue link to the new test * consensus/ethash: fix vet * consensus/ethash: fix test * consensus: tiny issue + nitpick fixes

| * consensus, core: EIP 100 polishes, fix chain maker diffPéter Szilágyi2017-06-301-29/+38
| | | | | | | | | | | | | | | | | | | | | | | | This PR polishes the EIP 100 difficulty adjustment algorithm to match the same mechanisms as the Homestead was implemented to keep the code uniform. It also avoids a few memory allocs by reusing big1 and big2, pulling it out of the common package and into ethash. The commit also fixes chain maker to forward the uncle hash when creating a simulated chain (it wasn't needed until now so we just skipped a copy there).

* | tests: update tests and implement general state tests (#14734)Felix Lange2017-07-111-2/+3
|/ | | | | | | | | | | | | | Tests are now included as a submodule. This should make updating easier and removes ~60MB of JSON data from the working copy. State tests are replaced by General State Tests, which run the same test with multiple fork configurations. With the new test runner, consensus tests are run as subtests by walking json files. Many hex issues have been fixed upstream since the last update and most custom parsing code is replaced by existing JSON hex types. Tests can now be marked as 'expected failures', ensuring that fixes for those tests will trigger an update to test configuration. The new test runner also supports parallel execution and the -short flag.

* | consensus: Fix `makedag` epochKonrad Feldmeier2017-06-121-2/+2
|/ | | | | | | | | `geth makedag <blocknumber> <path>` was creating DAGs for `<blocknumber>/<epoch_length> + 1`, hence it was impossible to create an epoch 0 DAG. This fixes the calculations in `consensus/ethash/ethash.go` for `MakeDataset` and `MakeCache`, and applies `gofmt`.

| | | | | | | | | | | | | | | | | | | | | | | | This commit is a preparation for the upcoming metropolis hardfork. It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)

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.
