[GRASS-dev] Issue with G76 in docker: creating a location fails in codecs.py

Hi,

while we meanwhile use GRASS GIS 7.6.svn in docker for months we ran
into this issue today:

root@52e6935c3247:/grassdb# grass76 --text c 'EPSG:4326'
/actinia_core/grassdb/latlongtest
Cleaning up temporary files...
Starting GRASS GIS...
Creating new GRASS GIS location <latlongtest>...
Traceback (most recent call last):
  File "/usr/local/bin/grass76", line 2162, in <module>
    main()
  File "/usr/local/bin/grass76", line 2075, in main
    geofile=params.geofile, create_new=True)
  File "/usr/local/bin/grass76", line 1005, in set_mapset
    create_location(gisdbase, location_name, geofile)
  File "/usr/local/bin/grass76", line 807, in create_location
    epsg=epsg, datum_trans=datum_trans)
  File "/usr/local/grass-7.6.svn/etc/python/grass/script/core.py",
line 1538, in create_location
    encoding='utf-8', mode='w')
  File "/usr/lib/python2.7/codecs.py", line 898, in open
    file = __builtin__.open(filename, mode, buffering)
IOError: [Errno 2] No such file or directory:
'/actinia_core/grassdb/latlongtest/PERMANENT/MYNAME'

... why that?

root@52e6935c3247:/grassdb# set | grep -i utf
LANG=C.UTF-8
LC_ALL=en_US.UTF-8

The directory is writable (I can mkdir the entire path without issues).

I wonder what I should look for here?

thanks for hints,
Markus

For the open() to create MYNAME (mode is w), /actinia_core/grassdb/latlongtest/PERMANENT/ needs to exist already. Without looking to the source code, I assume that create_location() is creating …/latlongtest/PERMANENT directories (I don’t expect it actually tests if it was successful unless the underlying Python function checks that).

If /actinia_core/grassdb/ is a volume, I would try the same in a directory which is not a volume. Creating minimal reproducible example would be my next step, naive, but could help.

For the open() to create MYNAME (mode is w), /actinia_core/grassdb/latlongtest/PERMANENT/ needs to exist already.

I see. But I’m using -c (user point of view).

Maybe we need this solution?

If /actinia_core/grassdb/ is a volume, I would try the same in a directory which is not a volume.

It is a volume outside the docker and mounted inside.

Creating minimal reproducible example would be my next step, naive, but could help.

The same docker image [1] doesn’t show this behavior on a different machine.

I’ll try a bit more.
