On OS X with 6.4RC4 and RC5 when using Config->GIS Working
Environment->Mapset Access I get the following error:

OSError
:
[Errno 2] No such file or
directory:
'/Users/rcline/grassdata/oakesModel/\ngridTest01sql'
Mapset Access fails because the mapset gridTest01sql begins with "\n".
This results because the g.mapsets -l returns multiple lines:
GRASS 6.4.0RC4 (oakesModel):~ > g.mapsets -l
aquiferBnd aquifers boresModel01 boresModel02 drains grid_tran01 grid_tran03
gridTest01sql oakes2 PERMANENT testAreaTopo
In lines 1800-1805 of preferences.py the call to g.mapsets -l is made on
line1800.
ret = gcmd.RunCommand('g.mapsets',
flags = 'l',
read = True)
mapsets =
if ret:
mapsets = ret.rstrip(' \n').split(' ')
In line 1805, ret.rstrip(' \n').split(' '), only the trailing line feed is
removed and not the line feed following the first line. Line 1805 should be
replaced with:
mapsets = ret.replace('\n','').split()
That way both the last line feed and any line feeds on multiple lines are
removed. Using .split() removes the need to handle the trailing space.
The change fixes the problem for me in 6.4RC4 and 6.4RC5. It also fixed a
crash when starting wxpython and opening an existing workspace. Can someone
with svn access verify my solution and fix this.
When invoking Mapset Access from the TclTK GUI, the search order was the
current mapset, Permanent, other mapsets in alphabetical order. With the
wxpython GUI, the search order is mapsets in alphabetical order. Was this
change intentional? It breaks some of my scripts, as I assumed that the
current mapset would always be searched first.
