What is the best way for a Python process (presumed to be a script run
by the interpreter binary, not embedded in some other program) to
restart itself? This is what I've been trying:
import __main__
for path in sys.path:
path += '/' + __main__.__file__
if os.access(path, os.F_OK): break
else:
raise Exception('WTF?')
#Then, something like...
os.execl(sys.executable, sys.executable, path, *sys.argv[1:])
BUT! This is a multi-threaded program, and at least on OS X, trying to
exec*() in a threaded process raises OSError [Errno 45] Operation not
supported. So I tried having it fork, and having the child process
wait for the parent process to die (in various ways) and then exec*().
That seemed to work, sort of, but the child would not be attached to
the original terminal, which is a must.
Any ideas?
