Tracking Issue for `process_setsid`

[HarveyHunt]

Feature gate: #![feature(process_setsid)]

This is a tracking issue for adding a setsid method to the std::os::unix::process::CommandExt trait.

Add a new setsid method to the CommandExt trait for UNIX systems. Using the setsid method, a caller can create a new session and process group whilst still benefiting from the POSIX spawn fast path code.

Public API

trait CommandExt {
    fn setsid(&mut self) -> &mut Command
}

It appears POSIX_SPAWN_SETSID is not actually defined in our libc crate anywhere except Linux.

It appears POSIX_SPAWN_SETSID is not actually defined in our libc crate anywhere except Linux.

Technically, I think it's also defined for Solaris, Illumos, Hurd and Haiku. But our standard library does not support using posix_spawn for those platforms, with the exception of illumos.
