AttributeError: 'NoneType' object has no attribute 'adaptor_class'

[trietptm]

I build the latest Voltron from GitHub and install in Windows following the instructions at https://github.com/snare/voltron/wiki/Installation#windbg and receive the following error in my WinDbg Command log:

0:000> .load pykd 0:000> !py --global C:\Python27\Lib\site-packages\voltron-0.1.5-py2.7.egg\voltron\entry.py C:\Python27\lib\site-packages\blessed\terminal.py:32: UserWarning: One or more of the modules: 'termios', 'fcntl', and 'tty' are not found on your platform 'win32'.

[snare]

Sounds like it hasn't installed the plugins properly. Can you try installing the Voltron package in develop mode?

$ cd voltron
$ pip uninstall .
$ pip install -e .

This will remove the Voltron egg from the Python packages directory, and create an egg-link to the source directory. Not a great solution, but might work for now. I'll investigate and see if I can reproduce the issue.

[trietptm]

The same adaptor_class problem still occurs:

Please ensure Voltron is installed correctly per the documentation: https://github.com/snare/voltron/wiki/Installation

[trietptm]

Now, I found a new script called voltron-script.py, is that the one I should execute?

[snare]

No, you should be loading entry.py. I am not able to reproduce this on Windows 7. Will try on a fresh system.

[snare]

Can you tell me which version of Windows, WinDbg and PyKD you're using?

[lazyhack]

My tested is version is..

OS : Windows 7 Ultimate K (Build 7601, SP1) WinDBG 6.12.0002.633 X85 PyKD 1.0.1.14 (downloaded the latest version yesterday) Python version 2.7.3 (32bit)

and.. I did below for the installation

1. I didn't execute install.sh because of My OS is Windows
2. Install the Pykd-0.3.0.38-py2-none-win_win32.whl
3. Install the Curses-2.2-cp27-none-win32.whl
4. python \setup.py install
5. then, On WinDBG, !py --global voltron\entry.py

C:\Python27\lib\site-packages\blessed-1.14.1-py2.7.egg\blessed\terminal.py:32: UserWarning: One or more of the modules: 'termios', 'fcntl', and 'tty' are not found on your platform 'win32'.

Traceback (most recent call last): File "c:\tmp\voltron-master\voltron\entry.py", line 57, in import voltron ImportError: No module named voltron

So, I copied Voltron folder to \Lib\Site-packages\volton

and The result is below..

What did I wrong?

Thanks

[snare]

I've tried to reproduce it and it seems that the install is failing on some of the dependencies. It would have thrown an error when you ran python setup.py install about the requests module not being available. If you then run the install again it will succeed on that dependency and fail on another one. If you run it 3 or 4 times it should get all the way through and successfully install. This has worked fine for me, and I can now load Voltron on a fresh machine. I'll investigate why the install is failing and fix it.

The AttributeError you're seeing indicates that the plugins aren't loaded properly, which says to me that your manual install method of copying the Voltron folder into site-packages hasn't worked as intended.

[lazyhack]

Yes! I did execute "python setup.py install" 3 times due to fail of installing some module. Then Should not I copy the Voltron folder into the site-packages folder manually? If I don't copy the Voltron folder into the site-packages folder, the ImporError of voltron occur. You mean I did wrong installation?

[snare]

You should not need to copy it manually, that's what the install does. What happens if you do this:

    > python -c "import voltron;print voltron" 

[lazyhack]

In the "manual copied" status => "< module 'voltron' from c:\python27\lib\site-packages\voltroninitpyc' >"

In the NOT "manual copied" status after python setup.py install => ImportError: No module named voltron

[snare]

So, when you ran python setup.py install 3 times it succeeded on the 3rd time? Can you run it again and verify it runs successfully? I cannot reproduce the install failing to install the module given running it enough times for the install to appear to have succeeded.

[snare]

And now run the command again:

> python -c "import voltron;print voltron" 

[lazyhack]

After "python setup.py install 3 times" I got the log volt_log.txt

[snare]

Have you removed all trace of your manually installed version of Voltron first?

[snare]

I cannot reproduce the AttributeError and strongly suspect it's still related to your broken manual "install"

[lazyhack]

I will try again on clean system. Thanks.

[lazyhack]

Still the problem exists.

I did again on the clean system "WITHOUT MANUAL COPY"

executed "python setup.py install" 3 times

• first, requests module fail.
• second, flask fail
• third, success
• Success automatically copied (voltron -> python)

"python.exe -c "import voltron;print voltron" => < module 'voltron ' from voltroninit.py' >

Same problem on windbg here.

[snare]

Ok, in the logs you posted above you are importing the Voltron entry point from the source directory. Can you please try importing the one that is now installed in site-packages?

[snare]

I'm just setting up a new environment to try to reproduce this

[snare]

I still can't reproduce the error.

[lazyhack]

Another problem.

I installed the voltron on other system. [Windows 7 x64, Windbg 6.12.0002.633 x86]

It seems to work normally,

but, Runtime Library error occured.

Attached file is the screeenshot

[snare]

I have no idea. Does other stuff work in PyKD now?

[lazyhack]

Yes, It seems to work fine. I will try next time. Thank you~! (I have to work back)

The stty is missing in Windows, so the view.window_size will throw error.

dbg_windbg.py

The dbg_windbg.py plugin currently has a logic to check if in_windbg or not by importing vtrace.

try:
    in_windbg = False
    import pykd
    try:
        import vtrace
    except:
        in_windbg = True
except ImportError:
    pass

However, vtrace module may exist in the system, e.x: vivisect will install vtrace, such that dbg_windbg.py will never be loaded.

Change it to as follows, the windbg plugin will load success, but voltron view still failed, due to stty issue. I haven't found a replacement of stty yet, what's your solution here? @snare

try:
    in_windbg = False
    import pykd
    if 'Microsoft (R) Windows Debugger Version' in pykd.dbgCommand('version'):
        in_windbg = True
except Exception:
    pass

[snare]

Re: stty, I've only ever used Voltron with Git Bash or ConEmu, and the GNU userland installed by Git which I suppose includes stty. I'll investigate a workaround, but in the mean time I'd suggest installing Git for Windows and using Git Bash or ConEmu.

Re: importing vtrace, vivisect is never installed as far as I know. It is used in-situ within the downloaded directory. There's no setup.py, etc, so as far as I can see, vtrace will never be in your Python path. Under what circumstances are you encountering this issue? IIRC the reason it works the way it does is because pykd will be importable from within the VDB adapter if the pykd package is installed in Python site-packages, but vtrace should never be importable from a script running in pykd. Your solution looks like it would incorrectly identify that it is running in WinDbg if it is in fact running in VDB if the pykd package is installed on the system.,

Re: your error output from loading Voltron, can you please try installing the Voltron package again per the previous discussion with @lazyhack and post your install log here? It seems that the install fails on dependencies a couple of times and needs to be run 3 times in order to install successfully. I haven't looked at this issue yet.

[binjo]

It turns I installed the vivisect from https://github.com/williballenthin/vivisect/, which includes a vtrace. :(

FTR, using full installation of Windows GIT, which includes stty, under bash, pip install voltron will succeed w/o error. voltron is usable, despite the error message from blessed\terminal. However the dependency of blessed module imports fcntl, which is not available in Windows, I couldn't find a resolution for this.

try:
    import termios
    import fcntl
    import tty
    HAS_TTY = True
except ImportError:
    _TTY_METHODS = ('setraw', 'cbreak', 'kbhit', 'height', 'width')
    _MSG_NOSUPPORT = (
        "One or more of the modules: 'termios', 'fcntl', and 'tty' "
        "are not found on your platform '{0}'. The following methods "
        "of Terminal are dummy/no-op unless a deriving class overrides "
        "them: {1}".format(sys.platform.lower(), ', '.join(_TTY_METHODS)))
    warnings.warn(_MSG_NOSUPPORT)
    HAS_TTY = False

In all, I'm giving up to use voltron under Windows, troublesome and I don't want to install a bunch of git tools in my analysis vm ;)

[snare]

Ahhh ok, I'll try to find a better method of detecting WinDbg and vtrace including support for Willi's fork of vivisect.

Windows/WinDbg support in general is quite new and needs some work. I've not yet investigated the blessed warning, but it doesn't actually effect the operation of Voltron so I've ignored it thus far. I may put some effort into supporting Windows without the Linux userland tools at some point, but my care factor for it is pretty low. However, I'll certainly be making sure it works properly under the new Windows 10 Linux userland without additional tools.
