Todd Gamblin 0aed3bcea6 spack edit: use execv instead of Executable (#11245) ... - `spack edit` previously used `spack.util.executable` `Executable` objects, and didn't `exec` the editor like you'd expect it to - This meant that Spack was still running while your editor was, and stdout/stdin were being set up in weird ways - e.g. on macOS, if you call `spack edit` with `EDITOR` set to the builtin `emacs` command, then type `Ctrl-g`, the whole thing dies with a `==> Error: Keyboard interrupt` - Fix all this by changing spack.util.editor to use `os.execv` instead of Spack's `Executable` object		2019-04-20 20:51:45 -07:00
