[New-bugs-announce] [issue39404] Pexpect : setwinsize() not working in SLES 12.4 kernel 4.12.14-94.41-default

[Archana Pandey]

New submission from Archana Pandey <archi.pandey9190 at gmail.com>:

use of setwinsize function returns empty if the values of rows and cols differes from(24,80).
Issue occurs only on SLES 12.4.

sample code:
#!/usr/bin/env python
from pexpect import pxssh
try:
    s = pxssh.pxssh()
    hostname = 'someIp'
    username = 'username'
    password = 'password'
    s.login(hostname, username, password)
    s.setwinsize(1000,1000)  # setting default winsize works
    s.sendline('uname -r')   # run a command
    s.prompt()             # match the prompt
    print(s.before)        # print everything before the prompt.
    s.logout()
except pxssh.ExceptionPxssh as e:
    print("pxssh failed on login.")
    print(e)
