Go: Updated to 1.5.2 & Added fasthttp benchmark

[valyala]

fasthttp is much faster than go's net/http

Fasthttp requires at least go1.5, while the benchmark uses older Go version (1.4.2) :(

So the following build errors appear:

Setup fasthttp: src/github.com/valyala/fasthttp/bytesconv.go:24: date.In(gmtLocation).AppendFormat undefined (type time.Time has no field or method AppendFormat)
Setup fasthttp: src/github.com/valyala/fasthttp/header.go:1171: undefined: bytes.LastIndexByte

Setup fasthttp: src/github.com/valyala/fasthttp/uri.go:269: undefined: bytes.LastIndexByte

Is it possible updating go version in the benchmark to the latest one?

@valyala This file should be the one to update to get the latest Go version.

I see that - this will probably effect all the various Go frameworks - a full Travis run will be required, but because Travis is broken on master, it won't work.

Once #1786 is merged in, you will need to merge it into your branch (or rebase your branch; I don't really care).

[valyala]

Is it possible to manually check all Go frameworks? I did check them few weeks ago on go 1.5.1 - it looks like nothing breaks.

[valyala]

BTW, go1.5 has huge latency improvements comparing to go1.4 - see this article for details.

[NateBrady23]

@valyala I am working on testing the Go frameworks now

[NateBrady23]

@valyala strike that - waiting for #1786 then will complete the tests

[valyala]

Go 1.5.2 is out. It contains many bugfixes, including the bugfix for the nasty bug. So I updated go version to 1.5.2.

[msmith-techempower]

@valyala Can you rebase off of master (or merge master into your branch, if that is easier) just to ensure that you have the latest Travis fixes?

[valyala]

@msmith-techempower , done!

Passed all the tests: https://travis-ci.org/TechEmpower/FrameworkBenchmarks/jobs/96284048

LGTM!
