tidwall cfc65a13f6 Refactor repository and build scripts
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

NUID

License MIT ReportCard Build Status Release GoDoc Coverage Status

A highly performant unique identifier generator.

Installation

Use the go command:

$ go get github.com/nats-io/nuid

Basic Usage


// Utilize the global locked instance
nuid := nuid.Next()

// Create an instance, these are not locked.
n := nuid.New()
nuid = n.Next()

// Generate a new crypto/rand seeded prefix.
// Generally not needed, happens automatically.
n.RandomizePrefix()

Performance

NUID needs to be very fast to generate and be truly unique, all while being entropy pool friendly. NUID uses 12 bytes of crypto generated data (entropy draining), and 10 bytes of pseudo-random sequential data that increments with a pseudo-random increment.

Total length of a NUID string is 22 bytes of base 36 ascii text, so 36^22 or 17324272922341479351919144385642496 possibilities.

NUID can generate identifiers as fast as 60ns, or ~16 million per second. There is an associated benchmark you can use to test performance on your own hardware.
