Python38 issue

I mentioned on another thread that I can’t run the Toolbox “!TbxTest” application as it errors. Now that I have discovered a way to capture the errors in full, I have included them here:

*SCSI::HardDisc0.$.Apps.Development.Python3.!TbxTest
Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = (not set)
  program name = 'SCSI::HardDisc0.$.Apps.Development.Python3.!Python3.python3'

  user site = 1
  import site = 1
  sys._base_executable = 'SCSI::HardDisc0.$.Apps.Development.Python3.!Python3.python3'
  sys.base_prefix = '\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd!!!!NULL.POINTER.DEREFERENCE!!!!'

  sys.path = [

    '\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd!!!!NULL.POINTER.DEREFERENCE!!!!',
    '\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd\xfd!!!!NULL.POINTER.DEREFERENCE!!!!',
  ]

<no Python frame> 

I’ve re-installed Python to solve the issue; other applications such as Boing and YTSearch work.

How do I add the missing module if that’s the issue?

Hello Andrew sorry you are having such trouble with the ToolBox test.
I have a fork of TbxTest which works consistently on my system.
So all we have to do is discover what is different between your system and mine :-)

If you wish you can download my test program and say what happens when you run it.

John, thank you, it did work last night. I returned to it this morning, and it gave the following error message:

Traceback (most recent call last):
  File "<tbxeg$Dir>.!RunImage", line 56, in <module>
    toolbox.initialise('<TbxTest$Dir>')
  File "SCSI::HardDisc0.$.!BOOT.Resources.!PythonSite.Python38.Site-Packages.riscos_toolbox.__init__/py", line 43, in initialise
    swi('MessageTrans_OpenFile', 'bsi', msgtrans_block,
swi.error: File name '.Messages' not recognised

On further investigation, clicking on TbxTest followed by tbxeg results in tbxeg working as expected; a green icon with an A appears on the icon bar, clicking it opens a window.

PS. I like the Ying/yang artwork, nice touch. :)

John, probably getting ahead of myself here, but I thought I’d try some of your “pytools” scripts to see if they might reveal something about my set-up.

boot_py – asks for an SSD – cancelled the disc not found error message.
show_lib_dir – filer error message, file not found, but the directory does exist.
show_py_vars – results below for this line and the following items
show_site_dir
show_user_dir
pip_list

show_py_vars reveals:

Hi Andrew

thanks for bug report – tbxeg should now work immediately;-

I will look into the tools tomorrow.

Thanks, John, it worked. :) Thank you for the time you’ve spent on this. :)

A final observation, a trivial thing; if you don’t quit tbxeg before performing a shutdown, it leaves the app on the icon bar with the shutdown dialogue on screen.

EDIT: Happy Holiday, John!

f you don’t quit tbxeg before performing a shutdown, it leaves the app on the icon bar with the shutdown dialogue on screen.

Looks as if it is not handling wimp Message_Quit.
I am on holiday now from tomorrow for a week and will try to fix it when I get back.

using back versions of riscos-toolbox

The riscos-toolbox library has been updated to 0.2.0 from 0.1.0
This causes !TbxTest to fail as it has not been updated to match.
Pip install only sees the latest version so you will need to download and install the older version 0.1.0 manually.
I suggest you save it inside the !TbxTest application directory where it will be seen and used in preference to the version in the path, and won’t be affected by system updates..

Download from here: riscos-toolbox

Download the Built Distribution file
    riscos_toolbox-0.1.0-py3-none-any.whl
Using NetSurf this downloads as
    riscos_toolbox-0/1/0-py3-none-any/whl
It comes in as type data. Change type to zip and open it
Drag the directory  riscos_toolbox to !TbxTest

Thank you for locating the old file.

!tbxeg is working again. :)

I’d half forgotton about this. Yes, riscos_toolbox 0.2.0 isn’t compatible with 0.1.0.

I keep meaning to get around to sorting out the toolbox lib, which includes an update to the sample program. It’s all been a bit hectic lately!
