也许是这样的?
# main.py
subprocess.call(["python", "pluginhandler.py", "plugin", env])
Then,
# pluginhandler.py
os.chroot(chrootpath)
os.setgid(gid) # Important! Set GID first! See comments for details.
os.setuid(uid)
os.execle(programpath, arg1, arg2, ..., env)
# or another subprocess call
subprocess.call["python", "plugin", env])
编辑:想使用 fork() 但我不太明白它的作用。查了一下。新的
代码!
# main.py
import os,sys
somevar = someimportantdata
pid = os.fork()
if pid:
# this is the parent process... do whatever needs to be done as the parent
else:
# we are the child process... lets do that plugin thing!
os.setgid(gid) # Important! Set GID first! See comments for details.
os.setuid(uid)
os.chroot(chrootpath)
import untrustworthyplugin
untrustworthyplugin.run(somevar)
sys.exit(0)
