Felix Lange	924065e19d	consensus/ethash: improve cache/dataset handling (#15864) ... * 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	7 years ago

Péter Szilágyi	09777952ee	core, consensus: pluggable consensus engines (#3817) ... 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.	8 years ago
Felix Lange	24dd0355a3	pow: fix Search with ethash test mode ... The cache/dataset methods crashed with a nil pointer error if cachesinmem/dagsinmem were zero. Fix it by skipping the eviction logic if there are no caches/datasets. Search always used the regular dataset size regardless of test mode. Fix it by removing the redundant size parameter of hashimotoFull. Fixes #3784	8 years ago
