> Another use of the deprecated unsafe preexec_fn was to call os.umask in the child prior to exec.
What do you mean by "deprecated"? The parameter doesn't seem to be deprecated in the documentation:
https://docs.python.org/dev/library/subprocess.html#subprocess.Popen
And when I use it, it doesn't emit any warning:
---
import os, subprocess, sys
def func(): print(f"func called in {os.getpid()}")
argv = [sys.executable, "-c", "pass"]
print(f"parent: {os.getpid()}")
subprocess.run(argv, preexec_fn=func)
---
Output:
---
$ ./python -Werror x.py
parent: 22264
func called in 22265
---
If you want to deprecate it, it should be documented as deprecated and emit a DeprecatedWarning, no? |
