Add OS info preceding tests about libuv HOT 12 CLOSED

The information shown is actually part of the actual test suite, since we test the output of some functions. There are currently no uv functions to provide OS information, do you have something in mind? I have a vague recolection of someone also asking for this long time ago.

As for the format, I'd stick to good old plaintext :-)

I didn't really consider including functionality for os information in libuv, rather just fiddling with uname/similar output. If you/they paste full configure output some parts show up, but that's just hard to read.

from libuv.

Well, that's autoconf at work... We'd need something cross platform, and parsing uname really isn't.

from libuv.

If we rely on autoconf we could "parse" its output (config.log)?

from libuv.

We don't rely on autoconf. That's one of the build systems, we also have GYP and on Windows / MinGW there is a dedicated Makefile.

@saghul, is this something you would still add to libuv? If so, I would take look.

from libuv.

I'm open to suggestions :-)

@saghul, I'm thinking something along the lines of uv_cpu_info_t, but for OS information.

typedef enum { android, aix, win, unix, darwin } uv_sys_kind_t;

typedef struct uv_kernel_version_s {
  int major;
  int minor;
  int patch;
  int build;
  char* extra_string;
} uv_kernel_version_t;

typedef struct uv_os_info {
  uv_sys_kind_t sys;
  char* sysname_string; /* "Windows", "Android" etc. */
  char* release_string; /* "Vista", "XP", "trusty" etc.*/
  uv_kernel_version_t kernel_version; /* structure to allow testing the versions numerically */
} uv_os_info_t;

/* Retrieve OS information */
int uv_os_info(uv_os_info_t*);

/* Pretty print OS information */
int uv_strosinfo(char*, uv_os_info_t*);

(just as a quick sketch, I need to familiarize myself with the project more, but you get the idea)

It might make sense to return the kernel version in a struct. As for the implementation, GetVersion&friends on Windows, uname on posix-friendly systems, plus trying to read /etc/lsb-release or issue etc. files. (I think it would be nice if the implementation detected the distributions on *nix).

Is this something like what you had in mind?

@sztomi thios is good work, thanks! I'll need a few days to work through the mail pile, but this is a good start IMHO.

from libuv.

Need this feature thanks

from libuv.

@saghul cool, then I'll try to whip out an initial implementation on my fork and let you know here when I have something to show.

No follow-up, closing. Feel free to open a PR when ready.
