* Rebase and fix compilation errors (tests not yet fixed)
* Use `debug_assert` over `assert`
* Fix tests
* Assert safety, clean up
* Fix up stale cache removal, move one assert to debug_assert
* Remove printlns
* Add licenses
* Fix benches
* Inline some no-ops in a hot loop that weren't being inlined
* Add spooky comment to make sure no-one removes the inlining annotations
* Minor cleanup
* Add option to switch between mmap and ram
* Flag ethash to use less memory when running light client
* Fix tests
* Remove todo comment (it's done)
* Replace assertion with error return
* Fix indentation
* Use union instead of `transmute`
* Fix benches
* Extract to constants
* Clean up and fix soundness holes
* Fix formatting
* Ignore missing-file errors
* Make incorrect cache size an error condition instead of a panic, remove dead code
* Fix compilation errors from rebase
* Fix compilation errors in tests
* Fix compilation errors in tests
* Fix benchmarks
* Fix unsoundness in uses of unsafety
* Remove most uses of unsafe indexing and ptr::copy_nonoverlapping
This commit also includes a completely absurd optimisation that I
promise is an honest win. You can check the benchmarks, I barely
believe it myself.
* Add safety comment
* Add more safety comments
I also tried unrolling the 256-iteration loop further below, but it actually caused a
slowdown (my guess is either branch prediction stopped kicking in or the instruction
cache was being maculated).
* clarify "cancelled periodic snapshot" message
* more rigorous checks for snapshot validity
* verify ancient blocks on import
* limit number of fed blocks
* make it possible to feed snapshot service canonical hashes
* fix failing test build
* swap ethash DAG only when more recent
Implementations of get_cache_size and get_data_size in Rust (issue #161)
