[RESOLVED] Package error following WAPT 2.0 update

[Alann]

Good morning,

I developed a package for post-installation configuration of Windows on my network, initially on WAPT 1.8.
The idea is to configure a newly installed workstation by finding its name from its IP address using a reverse DNS lookup.
For that, I use the dnspython module.

Since upgrading to WAPT 2.0, the installation returns an error: AttributeError: 'GenericRdata' object has no attribute 'target'

This error refers to a piece of code:

Code: Select all

def findmachinename(ip):
    pass
    no = dns.reversename.from_address(ip)
    answers = dns.resolver.query(no, 'PTR')
    for rdata in answers:
        nom = rdata
    nommachine = nom.target[0].decode("utf-8")
    return nommachine

The curious thing is that this code works perfectly when run locally on PyScripter, but it fails when deployed to workstations.

Any ideas?

Hi Alann,
is the dnspython package imported at the beginning of your code?
If that doesn't work, perhaps try packaging it with the other package?

[Alann]

At the beginning of the code I have a

Code: Select all

import dns.resolver
import dns.reversename

How do I package it with the package?

[Gaetan]

Is it possible to get the error output directly?

I restarted the installation on a freshly installed machine:

Code: Select all

Traceback (most recent call last):
  File "C:\Program Files (x86)\wapt\common.py", line 3841, in install_wapt
    setup = import_setup(setup_filename)
  File "C:\Program Files (x86)\wapt\waptutils.py", line 1498, in import_setup
    py_mod = imp.load_source(modulename, setupfilename)
  File "imp.py", line 171, in load_source

  File "C:\windows\TEMP\wapt48wx8rls\setup.py", line 5, in <module>
ModuleNotFoundError: No module named 'dns'
ModuleNotFoundError: No module named 'dns'

Apparently, I need to integrate the dnspython module into the wapt package. I don't know how to do it...

Hi Alann,
the dnspython library shouldn't be very large; it's best to include it in the package. You can download the zip file from https://pypi.org/project/dnspython/#files , then extract the "/dns" directory from it and place it in the root directory of your package next to setup.py.

Denis

Hello Denis, and thank you for your reply.

It works perfectly.

The solution was so simple...

[Alann]

If I had to nitpick, there would just be one point:

The audit on the machines gives the same error message, even though the installation is OK.

Code: Select all

Audit aborted due to exception: No module named 'dns'

Hello Alann,

is it possible to get the complete package code?

[Alann]

Problem solved.

It was simply a matter of placing the "dns" folder from the PyDSN module in the package.

Remember to also create a copytree to add it to the clients' WAPT libraries; otherwise, package auditing will return an error.
