The port generally looks good.
I found DESCR a bit confusing (bbolt vs Bolt) as I wasn't aware of the
history, I've rewritten it a bit which I think is a bit easier for me
to understand.
"make test" fails for me, log below. I don't know if that's important.
bbolt implements a low-level key/value store in pure Go. It supports
fully serializable transactions, ACID semantics, and lock-free MVCC with
multiple readers and a single writer.
It is a fork of Ben Johnson's "Bolt" key/value store aimed at providing
the Go community with an active maintenance and development target for
Bolt.
Bolt can be used for projects that want a simple data store without the
need to add large dependencies such as Postgres or MySQL.
Bolt is a single-level, zero-copy, B+tree data store. This means that
Bolt is optimized for fast read access and does not require recovery
in the event of a system crash. Transactions which have not finished
committing will simply be rolled back in the event of a crash.
The design of Bolt is based on Howard Chu's LMDB database project.
