pypledge 0.3.1

Binding for the OpenBSD pledge(2) system call

def pledge(promises: Optional[Iterable[str]] = None,
           execpromises: Optional[Iterable[str]] = None) -> None: ...

Throws OSError if the platform does not support pledge(2) or if the pledge fails.

Example

The following will restrict the current process to only the stdio and tty promises, and then attempt to violate that restriction:

import pypledge
pypledge.pledge(['stdio', 'tty'])
f = open('foo.txt')

On OpenBSD 5.9, this will terminate with SIGABRT because the rpath promise was required.

On other platforms, this will throw OSError.
