Incorrect file path separator in Processing GRASS tools

Assignee:Victor Olaya
Affected QGIS version:2.18.16 Regression?:No
Operating System:Windows 10 x64 Easy fix?:Yes
Pull Request or Patch supplied:Yes Resolution:fixed/implemented
Crashes QGIS or corrupts data:No Copied to github as #:26076


When running i.maxlik from the GRASS7 tools in the Processing toolbox, the command fails when copying the signature file to the temporary GRASS mapset. The failure is due to the default Windows file path separator (\) being altered to a Linux one (/) by the tool script.

This has been previously reported here:

A fix is supplied in the form of a patch to the copyFile function in the GRASS i. Processing utils module here:
<QGIS Install Dir>\apps\qgis\python\plugins\processing\algs\grass7\ext\i.py

However the alteration of the path occurs in the getParameterValue function.
