Add fs.statvfs function to get disk size/free/available space + other info

[miniak]

There is no build in way to get disk space information. There are a few npm modules available:

• https://www.npmjs.com/package/diskusage (has 8 dependencies, including FFI, which is quite ridiculous, proposed reimplementation in C++: Re-implement in C++ with just NaN dependency jduncanator/node-diskusage#14)
• https://www.npmjs.com/package/diskspace (depends on an EXE file on Windows)

This is such a basic API that should be built-in.

libuv would need to add such support first, then node would add an API that uses that libuv API.

From what I can tell, the modules you linked to only provide a subset of what statvfs(). libuv would also require a Windows implementation. It looks like Python rejected a Windows implementation a while back (not sure if that has since changed).

@miniak I use https://www.npmjs.com/package/storage-device-info, which only depends on NAN. Regardless though, it would be nice to have this built-in.

I'm not opposed to it, proven that there is a reasonable implementation for all our supported platforms.

Given that this issue has been inactive for several months, is it sensible close this (or at least mark is at blocked) unless and until the necessary features are added to libuv?

[ronkorving]

I think this is still valid, regardless of people having have spent time on it.

[gengjiawen]

https://github.com/jduncanator/node-diskusage now implements in C++, it also have a Windows implementation.

So is this happening or not? I see it on the project dashboard but it's now closed?
