Support more OSes (WIP) #3

I was assigned this for Feb in the PR challenge:

So, this PR attempts to broaden the OS support. The POSIX::sysconf call should work on basically any *nix. If sysconf fails or we know it's not available, we fall back to a system-specific command to get num cores from /proc, environment, etc.


  • Check out robustness of sysconf across any platforms I can get my hands on.
  • Create more fallbacks (multiple per-OS?).
  • Count processors online vs processors configured?

I'm opening the PR at this stage to find out whether you like the look of the changes or not - if not, I'll back off. If so (or if I hear nothing), I'll continue :)


jbarrett added some commits Feb 9, 2015

Attempt sysconf(3) to get processor count, with command line fallback.
This should open up support for a wider array of OSes.
Don't use FFI for functions exported in POSIX.
This attempts to use sysconf SC_NPROCESSORS_ONLN to cover processor
count retrieval on all *nix.

Thanks @xdbr - I wasn't quite finished (could add more fallbacks for common OSes, *BSDs at least) but not to worry, can open another PR when I get round to those.
