Build fails on Windows

[Hydrocharged]

What's going wrong?

I attempted to run the tests on Windows, and the following is the output:

$ go test ./... --count=1
# github.com/pilosa/pilosa/syswrap
syswrap\mmap.go:53:14: undefined: syscall.Mmap

Steps to reproduce the behavior

Navigate to the base folder and run go test ./... on a Windows machine. --count=1 is not required for the reproduction of the issue.

Information about your environment (OS/architecture, CPU, RAM, cluster/solo, configuration, etc.)

Windows 10 Pro 64-bit
go version go1.12.1 windows/amd64

Additional Information

It looks like the syscall.Mmap and syscall.Munmap calls have been deprecated, and are Unix-specific calls. They're available on both Linux and MacOS platforms:

https://golang.org/pkg/syscall/?GOOS=linux#Mmap
https://golang.org/pkg/syscall/?GOOS=darwin#Mmap

But the function cannot be found on Windows:

https://golang.org/pkg/syscall/?GOOS=windows

@Hydrocharged Thank you for the report. Pilosa depends heavily on memory-mapped files, which are unsupported on Windows, and there are no plans to support Windows natively.

For development in Windows, I recommend trying to run either in Docker or in a virtual machine (ie. Virtualbox). We have published a guide for running Pilosa in Docker for Windows here: https://www.pilosa.com/docs/latest/installation/#windows

Please file a separate ticket if you encounter problems running Pilosa in Docker.
