1) Instead of checking for utf-8 in particular, I would
prefer a more
robust approach:

try:
       qr = qrcode.QRCode()
       qr.add_data('test')
       qr.make()
       qr.print_ascii(tty=True)
except UnicodeError:
       # it is not printable
else:
       # it is printable

Now you mean the check in the _check_qrcode_capability() or
the
_print_qrcode() method itself?
_check_qrcode_capability() of course.






2) There is no os.isatty() check to see if stdout is
actually
a tty.

This check is performed inside both print_ascii() and
print_tty()
methods of QRCode object, but you probably mean that I
should
put the
check also into _check_qrcode_capability() method, right?
Yes. If stdout is not a tty, we should at least not tty=True
in
print_ascii().

Attaching updated patch. After the discussion with other
developers
we
decided to just print warnings when non-UTF-8 encoding is used
and
tty
width is smaller that the QR code size.



Found some minor errors in the patch, attaching updated version.
NACK

This patch has the major problem that tokens are added but then
unusable because they can't be provisioned to the devices. You need
to
check if qrcode output is possible before the token is added to
LDAP.
We discussed this on the IPA devel meeting and the decision was that
since the otpauth URI is always displayed, a warning is sufficient
when
the QR code cannot be printed.

If you disagree, could you explain why the URI is not sufficient for
provisioning the token?

I guess that is okay.


Thank you Nathaniel.

Jan had some offline comments to the patch. Attaching updated version.



Attaching updated patches.



I fixed the warning message when the QR code can not be rendered.

Attaching updated patches.



6th time the charm.

Thanks, ACK.
