[Pulp-dev] cli without TTY fails with "IOError: [Errno 25] Inappropriate ioctl for device"

[Andreas.Piesk at voeb-zvd.de]

Hello list,

i have the issue described in https://pulp.plan.io/issues/4068, it's not 
entirely fixed:

$ echo bla | while read A; do pulp-admin rpm repo list --repo-id $A; done
Traceback (most recent call last):
  File "/usr/bin/pulp-admin", line 9, in <module>
    load_entry_point('pulp-client-admin==2.21.1', 'console_scripts', 
'pulp-admin')()
  File "/usr/lib/python2.7/site-packages/pulp/client/admin/__init__.py", 
line 9, in main
    exit_code = launcher.main(read_config(), 
exception_handler_class=AdminExceptionHandler)
  File "/usr/lib/python2.7/site-packages/pulp/client/launcher.py", line

    extensions_loader.load_extensions(extensions_dir, context, role)

    self.download_bar = self.prompt.create_progress_bar()

    width = self.terminal_size()[0]

terminal_size
    ioctl = fcntl.ioctl(0, termios.TIOCGWINSZ, struct.pack('HHHH', 0, 0, 
0, 0))
IOError: [Errno 25] Inappropriate ioctl for device

It's not only terminal_size() called from pulp, okaara itself calls 
terminal_size() internally:

$ echo bla | while read A; do pulp-admin rpm repo list --repo-id $A; done

0, 0))
IOError: [Errno 25] Inappropriate ioctl for device

Workaround is to disable wrap_to_terminal in admin.conf and consumer.conf:

#wrap_to_terminal: true
wrap_width: 80
