OK, this being Windows security, there's a couple
of hoops to jump through, but nothing too bad.
<code>
import win32api
import win32security as sec
#
# This function is merely window-dressing
# to make it easier to see whether the
# code has worked or not.
#
def priv_status (hToken, priv):
for p, status in sec.GetTokenInformation (
hToken,
sec.TokenPrivileges
):
if p == priv:
if status == 0:
return "disabled"
else:
return "enabled"
else:
return "disabled"
process = win32api.GetCurrentProcess ()
token_access_flags = sec.TOKEN_ADJUST_PRIVILEGES | sec.TOKEN_QUERY
hToken = sec.OpenProcessToken (process, token_access_flags)
debug_priv = sec.LookupPrivilegeValue (None, sec.SE_DEBUG_NAME)
print "Debug is", priv_status (hToken, debug_priv)
privs = [(debug_priv, sec.SE_PRIVILEGE_ENABLED)]
sec.AdjustTokenPrivileges (hToken, 0, privs)
print "Debug is", priv_status (hToken, debug_priv)

Not to say that there could never be one, but I suspect
that the difference of APis and the number of corner
cases makes it a daunting task for maintenance. The
code would have to work on every platform Python works
on -- which is no small number -- and would have to be
maintained across the many and varied changes on each
of those platforms.
Still, if you think you're in with a chance, go ahead
and offer :)
Let us know if the DEBUG priv thing works or not.
