Public bug reported:
Running any instance of wicd, wicd-client, wicd-curse, wicd-gtk will
result in a line output to stdout as so:
# sudo wicd --version
rename failed
wicd 1.7.0 (bzr-r552)
wireless (and wired) connection daemon.
Arguments:
-a --no-autoconnectDon't auto-scan/auto-connect.
-f --no-daemon Don't daemonize (run in foreground).
-e --no-stderr Don't redirect stderr.
-n --no-poll Don't monitor network status.
-o --no-stdout Don't redirect stdout.
-h --help Print this help.
The "rename failed" exception is consistent, on both 32-bit and 64-bit,
whether run sudo or as user.
I have traced the problem to the function RenameProcess(new_name) in the
file /usr/share/pyshared/wicd/misc.py.
The function does a test for the existence of the libc.so.6 library, by
first trying to determine whether it's on a 64-bit or a 32-bit system.
Depending on which arch is found, the function then sets the path to the
lib.
This path is now wrong for 11.04.
Original function is:
def RenameProcess(new_name):
""" Renames the process calling the function to the given name. """
if sys.platform != 'linux2':
print 'Unsupported platform'
return False
try:
import ctypes
is_64 = os.path.exists('/lib64/libc.so.6')
if is_64:
libc = ctypes.CDLL('/lib64/libc.so.6')
else:
libc = ctypes.CDLL('/lib/libc.so.6')
libc.prctl(15, new_name, 0, 0, 0)
return True
except:
print "rename failed"
return False
Actual paths within the function should be:
def RenameProcess(new_name):
""" Renames the process calling the function to the given name. """
if sys.platform != 'linux2':
print 'Unsupported platform'
return False
try:
import ctypes
is_64 = os.path.exists('/lib64/x86_64-linux-gnu/libc.so.6')
if is_64:
libc = ctypes.CDLL('/lib64/x86_64-linux-gnu/libc.so.6')
else:
libc = ctypes.CDLL('/lib/i386-linux-gnu/libc.so.6')
libc.prctl(15, new_name, 0, 0, 0)
return True
except:
print "rename failed"
return False
