Possible unexpected crash on Windows

[triplus]

I can't test this on Windows, but during FreeCAD start on Windows, it looks like a standard Python exception could result in a FreeCAD crash. An example:

Code: Select all

C:\Users\user_name\AppData\Roaming\FreeCAD\Mod\Demo\InitGui.py

Containing code:

Code: Select all

import os
import FreeCAD as App

os.listdir(App.getUserAppDataDir() + "Demo")

On Linux i don't experience the crash. Two reports, that are likely related, if the above example can be confirmed by others:

Hi @Syres

Thanks for testing. Could you by any chance test with FreeCAD 0.17:

https://github.com/FreeCAD/FreeCAD/releases/tag/0.17

Just to confirm the suspicion, this issue was once present on Windows, but should be fixed in FreeCAD 0.18.

@Triplus, both 0.17 and 0.16 produce exactly the same output as the 0.18 Py2Qt4 build with no crash.

Hi @renatorivo

Such output looks related to Py3 issues some FreeCAD modules might currently have. Best to test with the latest version of each module. If the issue persist, opening an issue report and make the developer aware of the issue makes sense.

@Syres

Therefore likely this was/is not a general issue. Thanks for confirming.

No crash here. I tried:

Code: Select all

import os
import FreeCAD as App

os.listdir(App.getUserAppDataDir() + "Demo")

...which errored that path not found, and:

Code: Select all

import os
import FreeCAD as App

os.listdir(App.getUserAppDataDir() + "Mod\Demo")

...which gave no error
In both cases, FreeCAD launched normally.

No crash here.

Thanks for confirming.

P.S. This doesn't look like a general issue anymore too me and hence it can be dismissed.

Start from 0.19.2.7b5e18a-WIN-x64 installer (and any time thereafter) crashes after showing initial UI for 2sec on Windows 7.

Start of 0.18.4 on same machine/user works without a hitch:
OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.4 (GitTag)
Build type: Release
Branch: releases/FreeCAD-0-18
Hash: 980bf9060e28555fecd9e3462f68ca74007b70f8
Python version: 3.6.6
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)

Referring to possibly related case https://forum.freecadweb.org/viewtopic. ... 30#p295022, I tried to remove the Demo scheme, but being the UI only idiot I am, I don't know how to start it (double-clicking just flashes a DOS window). Documentation issue: InitGui.py is not in "C:\Users\user_name\AppData\Roaming\FreeCAD\Mod\IconThemes\", but in "C:\Program Files\FreeCAD 0.19\Mod\AddonManager\",

Sorry for the hand holding I need, where do I find the logs that you need?

Thank you!

They are in C:\Users\user_name\AppData\Roaming\FreeCAD. You have to invoke FreeCAD with the additional commandline parameter "-l" (small letter L).
