[New-bugs-announce] [issue37586] macOS: posix_spawn(..., setsid=True)

[Ronald Oussoren]

New submission from Ronald Oussoren <ronaldoussoren at mac.com>:

The Xcode 11 beta introduced a definition for POSIX_SPAWN_SETSID, but that flag is only supported on macOS 10.15 (also beta), not on earlier versions.

Because of this the testsuite will have failures when you build using Xcode 11 on macOS 10.14. 

I'm not sure what the best way to patch this is, but lean toward a fix that detects the use of setsid=True on macOS 10.14 or earlier and then fails. Possibly as part of a larger effort to start supporting building on macOS "latest" and running on older versions.

Marked as low priority for now, Xcode 11 is in beta and not used to build release binaries.
