Ugh... that's just not fair. Because of this there will be no spawn*p*
in python for another two years. x_x
I have a workaround for this, that tweaks os module:
[...snip wrong code...]
It should have been:
if (not (hasattr(os, 'spawnvpe') or hasattr(os, 'spawnvp'))
and hasattr(os, 'spawnve') and hasattr(os, 'spawnv')):
def _os__spawnvpe(mode, file, args, env=None):
import sys
from errno import ENOENT, ENOTDIR
from os import path, spawnve, spawnv, environ, defpath, pathsep, error
if env is not None:
func = spawnve
argrest = (args, env)
else:
func = spawnv
argrest = (args,)
env = environ
head, tail = path.split(file)
if head:
return func(mode, file, *argrest)
if 'PATH' in env:
envpath = env['PATH']
else:
envpath = defpath
PATH = envpath.split(pathsep)
if os.name == 'nt' or os.name == 'os2':
PATH.insert(0, '')
saved_exc = None
saved_tb = None
for dir in PATH:
fullname = path.join(dir, file)
try:
return func(mode, fullname, *argrest)
except error, e:
tb = sys.exc_info()[2]
if (e.errno != ENOENT and e.errno != ENOTDIR
and saved_exc is None):
saved_exc = e
saved_tb = tb
if saved_exc:
raise error, saved_exc, saved_tb
raise error, e, tb
def _os_spawnvp(mode, file, args):
return os._spawnvpe(mode, file, args)
def _os_spawnvpe(mode, file, args, env):
return os._spawnvpe(mode, file, args, env)
def _os_spawnlp(mode, file, *args):
return os._spawnvpe(mode, file, args)
def _os_spawnlpe(mode, file, *args):
return os._spawnvpe(mode, file, args[:-1], args[-1])
os._spawnvpe = _os__spawnvpe
os.spawnvp = _os_spawnvp
os.spawnvpe = _os_spawnvpe
os.spawnlp = _os_spawnlp
os.spawnlpe = _os_spawnlpe
os.__all__.extend(["spawnvp", "spawnvpe", "spawnlp", "spawnlpe"])
But the fact that I have to use similar code anywhere I need to use
spawnlp is not fair. Notice that _spawnvpe is simply a clone of
_execvpe from os.py, maybe if the problem is new API in c source, this
approach could be used in os.py?
P.S. Although it's a bit stretching, one might also say that
implementing spawn*p* on windows is not actually a new feature, and
rather is a bugfix for misfeature. Why every other platform can
benefit from spawn*p* and only Windows can't? This just makes
os.spawn*p* useless: it becomes unreliable and can't be used in
portable code at all.
