Hash: use optimized rotation constants.
...
Also use random constants for the initial hash state. Changed my
mind about using zero initialization. It doesn't make a practical
difference, but helps esnure that the mixing is randomized.

Hash: convert to hex string in a simpler way.

Add one more test for the hash.

Hash: start with a state of zero.
...
This doesn't affect the quality of the hash at all, and an empty
message hashing to zero is kind of nice.

Use hash perf leeway from prior commits to make the hash higher quality.
...
When incorporating a data block into the hash, it now does enough
mixing rounds to flip on average about 110 bits for any bit flipped
by the data block.
This reduces performance again, but not all the way to what they
were before. It's still reasonably fast, hashing at around 6-7 GB/s.

Slightly easier-to-modify hash code.
2022-08-25 19:56:38 -07:00

Significant speed up to the hash.
...
It can now hash data at 9-10 GiB/s.

Also added a couple new ones to test possible edge cases.
2020-02-24 12:33:36 +09:00
e810503e56
Slight tweak to the hash function.
...
The last swap isn't actually needed, and this makes the implementation
cleaner for different numbers of rounds if we want to tweak that
later.
2020-02-24 10:18:58 +09:00

Beginnings of an undo system for the new backend.

Just going to keep it stupid and simple for now. More
sophisticated undo functionality can be added in the future.

Gutter styling improvements.
...
Instead of having the hard line numbers alternate colors, give soft
wrapped lines their own lighter color. This still gives a nice
visual cue when lines are wrapped, but isn't as generally distracting.
2020-02-17 18:47:43 +09:00
