[Bug] Error in console on startup : Error reading WIND file, Windows, Grass 8.3.1

[echoix]

Describe the bug When GRASS GIS launch with temporary location tmploc (dir C:\Users\User\Documents\grassdata was renamed/moved) error message is printed into CMD.

To Reproduce Steps to reproduce the behavior:

1. When dir C:\Users\User\Documents\grassdata exists rename it to e.g. data
2. Launch GRASS GIS
3. See error in GRASS GIS CMD session (GUI normally start)

C:\Users\User>
ERROR: Unable to read WIND file: not enough values to unpack (expected 2, got 1)

Coordinate system:

C:\Users\User>g.proj -p
XY location (unprojected)

Expected behavior Error message should not be printed into CMD when GRASS GIS start with default unprojected tmploc location.

System description (please complete the following information):

• Operating System: MS Windows
• GRASS GIS version: 8.3, 8.4.dev

@isaacnewtonfx Does this happen in any mapset?

Could you attach the content of the WIND file? When you run g.gisenv in the terminal, the WIND file will be in GISDBASE/LOCATION_NAME/MAPSET folder. I wonder if there is an empty newline somewhere in that file.

Hi @petrasovaa this is it.

[isaacnewtonfx]

And here is the content of my GRASS_GIS_DATABASE folder

@petrasovaa I just noticed that my GRASS is pointing to a tmploc which does not exist in my GRASS DATABASE. I have changed the location to my existing WGS84 location and restarted GRASS.

It works now without throwing any errors when I launch GRASS.

I confirm this behavior under MS Windows OS when grassdata directory was renamed/moved (~first run of GRASS GIS~) with tmploc location.
