FreeCAD crash with empty PATH on windows

[lorenznl]

Hi,

is FreeCAD supposed to run properly with an empty PATH variable?

• OS: Windows 7
  Platform: 64-bit
  Version: 0.14.2778 (Git)
  Branch: master
  Hash: 0506a918b24e015ac6277a7cf613ce151e1dee44
  Python version: 2.6.4
  Qt version: 4.5.3
  Coin version: 2.4.5a
  SoQt version: 1.4.1
  OCC version: 6.3.0

running FreeCAD from a command prompt and clearing the path with "path ;" or "set PATH=" nets me the following error dialog

• ---------------------------
  Initialization of FreeCAD failed
  ---------------------------
  While initializing FreeCAD the following exception occurred: '('PATH',)'
  
  Python is searching for its files in the following directories:
  c:\Program Files\FreeCAD_0.14.2778_x64\bin\python26.zip;.\DLLs;.\lib;.\lib\plat-win;.\lib\lib-tk;c:\Program Files\FreeCAD_0.14.2778_x64\bin
  
  Python version information:
  2.6.4 (r264:75706, Mar 10 2010, 13:07:26) [MSC v.1500 64 bit (AMD64)]
  
  Please contact the application's support team for more information.

while any one character - not neccessaryly representing a regular or existing path - results in FreeCAD starting without problems

Apparently not. But setting

Code: Select all

set PATH=.

works. I think the reason for the failure is not that the DLLs are not find but a malfunction of Python.

OK, Python failed inside out init script which tried to access the 'PATH' environment from Python. If you empty the PATH before this key doesn't exist and raises a KeyError. This is now handled properly in git show c565cf0
