I've been experimenting for a while with a new brotli compressor.
Instead of being a translation of the C implementation,
it's a rewrite in Go, with a modular structure thanks to interfaces.
(A few low-level functions still come from the C version, though.)
The performance is getting to the point where it seems to be worth
adding to the brotli repository.
When a Reader encounters an error, its internal state may be corrupted.
So Reset needs to be extra thorough, to avoid cascading errors.
Based on PR 37 by Sovianum.
Use 64- or 32-bit loads instead of reading a byte at a time. The
original C source did something like this, in a very C-ish way. It
needed to be simplified to translate it to Go. The exact way this works
was suggested by the assembly code in github.com/golang/snappy.
