bug#32810: It 100% Bug (Output contains controlled symbols)

[ПИван Петров]

If replace "parted --machine /dev/sdb unit B print free quit" execution by Python script:

#========== Python script =====================

#!/usr/bin/env python3

# -*- coding: utf-8 -*-

import subprocess;

def GetPartedOutput(diskPath):

result = {}

commandParams = ['parted', '--machine', diskPath, \

'unit', 'B', 'print', 'free', 'quit']

runObj = subprocess.run(commandParams, \

stdout=subprocess.PIPE, \

stderr=subprocess.PIPE, \

check=True)

errorsOutput = runObj.stderr.decode('utf-8')

output = runObj.stdout.decode('utf-8')

hexiText = "".join("({}_{:02x})".format(letter, ord(letter)) for letter in output)

print(errorsOutput + output)

print('========== hexiText ==========')

print('ou:' + hexiText + ':ou')

GetPartedOutput('/dev/sdb')

#========== End Python script ==================================

================ Then will be Output: ==============

=============== End Output ===========================

1. This "Output" contains "Carrage return" as 1st simbol

2. Then contains a lot of spaces.

3. After "BYT;" - has symbol, that i can't recognaize (I am not cool Python programmer :-) )

4 and than goes 3 spaces (after this symbol)

I think, that it is very bad output/ These symbols not must be in output!!!

PS: Before, i rebooted and a lot of spaces was after "BYT;" (but i have not this python script)
