This commit includes updates that affects the build, testing, and
deployment of Tile38.
- The root level build.sh has been broken up into multiple scripts
and placed in the "scripts" directory.
- The vendor directory has been updated to follow the Go modules
rules, thus `make` should work on isolated environments. Also
some vendored packages may have been updated to a later
version, if needed.
- The Makefile has been updated to allow for making single
binaries such as `make tile38-server`. There is some scaffolding
during the build process, so from now on all binaries should be
made using make. For example, to run a development version of
the tile38-cli binary, do this:
make tile38-cli && ./tile38-cli
not this:
go run cmd/tile38-cli/main.go
- Travis.CI docker push script has been updated to address a
change to Docker's JSON repo meta output, which in turn fixes
a bug where new Tile38 versions were not being properly pushed
to Docker

xxhash
xxhash is a Go implementation of the 64-bit xxHash algorithm, XXH64. This is a high-quality hashing algorithm that is much faster than anything in the Go standard library.
The API is very small, taking its cue from the other hashing packages in the standard library:
$ go doc github.com/cespare/xxhash !
package xxhash // import "github.com/cespare/xxhash"
Package xxhash implements the 64-bit variant of xxHash (XXH64) as described
at http://cyan4973.github.io/xxHash/.
func New() hash.Hash64
func Sum64(b []byte) uint64
func Sum64String(s string) uint64
This implementation provides a fast pure-Go implementation and an even faster assembly implementation for amd64.
Benchmarks
Here are some quick benchmarks comparing the pure-Go and assembly implementations of Sum64 against another popular Go XXH64 implementation, github.com/OneOfOne/xxhash:
| input size | OneOfOne | cespare (purego) | cespare |
