error message v.db.addcol

[jradinger]

When trying to add a new column (v.db.addcol map=basins@test columns=area DOUBLE) following error message is produced. Anyway the column is created and there seems no problem with the database table. Just the error message:

For shell debugging, please change the first line of /Applications/GRASS-6.5.app/Contents/MacOS/scripts/v.db.addcol from

#!/bin/sh

to

#!/bin/sh -x

and run it again. Then post the relevant error part here, thanks.

Here the shell output after running v.db.addcol in shell with changed first line:

The problem is the white space in the path not handled properly:

--> ADDON_PATH is broken into two lines.

[hamish]

The immediate culprit is eval g.gisenv,

The underlying fix is to not store the addon path as a GRASS variable, store it as a shell environment variable -- and only a shell variable -- instead.

Remove it from the g.gisenv list with:

g.gisenv set="ADDON_PATH="

then v.db.addcol should be happy.

Trying to make it both a shell environment variable and a grass variable is well intentioned, but blurring definitions so that things can be set and read independently in multiple places using the same namespace is ultimately going to create more problems than it solves. The main question I think is if we need some other place besides .grass.bashrc to store this sort of thing, to be sourced by the grass startup script. ? (currently for grass6 it needs to be set in ~/.bashrc since .grass.bashrc is sourced later in the startup script.

The GUI can modify its own running environment on the fly with os.environ(); command line users who want to modify their environment generally can, and indeed want to, take care of themselves.

cheers, Hamish

n.b. the eval g.gisenv will still be problematic if the GISDBASE path contains a space. In this case just the MAPSET name is needed, so eval g.gisenv MAPSET avoids trouble, but quoting by g.gisenv is something we should probably discuss.

(nonetheless, having GRASS_ADDON_PATH enviro var and ADDON_PATH grass var is unfortunate)

Hamish

[hamish]

devbr6/scripts$ svngrep -r g.gisenv * | grep eval | cut -f1 -d: | uniq | wc -l
37

v.db.addcol restricted to just eval'ing MAPSET in devbr6 r52299, but many still to audit. :-(

Backported to 6.4.svn, too.

I tried again with the first example (streams@test). No problems occured. Anyway another mapset still produces error messages:

So far as I can see there is no whitespace in the mapset. Tested on Ubuntu 12.04 with Grass6-devel r52671. This might be related to ticket #1696.

(see comment:5)

what does g.gisenv by itself on the command line show?

does you mapset have a space in it? (AFAIU you should have gotten an error when you tried)

sorry for responding so late.

today I tried example again and found out that the error messages are related a messy gisenv. Here first the errors from v.db.addcol

v.db.addcol map="test@FIDIMO_Cele" columns="testcol DOUBLE"

So I also checked the output of g.gisenv from the command line which seems somehow wrong. I looks like the output for GRASS_SCRIPTS is "chopped up" and messy, and I don't know how this could happen.

How can I clean up my gisenv as I think that might solve the problem? Whats the best way? My ADDON_PATH is extremely long and repeatedly the same. Furthermore it seems there is a line break in gisenv dividing "r" and "adinger...", which is causing the problem above.

I still don't know how this could happen as I never touched the gisenv deliberately.

[jradinger]

And no, my mapset generally don't have any spaces in it, just to avoid such problems

The repetitions in ADDON_PATH could be caused by a bug in g.extension. You could try to manually edit ~/.grass7/rc.

ditto, better a late response than none :)

In GRASS 6 the file is ~/.grassrc6, and you should not be in a GRASS session when you edit it.

I have had another attempt at making v.db.addcol more robust to external g.gisenv problems in r55162,3. This report should stay open until the other ~36 scripts that use eval g.gisenv but only really need one variable from it have been checked/fixed. Spaces and other fun chars in GISDBASE will make eval unhappy.

Hi,

scripts in devbr6 now updated with r55194:55226, but need testing before backport to the stable branch.

AFAICT the only ones which will actually trigger run-time processing errors (instead of just the occasional harmless message) on WinGrass w/ spaces in GISDBASE, are:

• r.pack/unpack (already backported)
• r.in.srtm
• db.droptable
• d.rast.leg (bug? try erode.index@spearfish)
• r.in.wms
• i.image.mosaic
• v.in.garmin (doesn't need to be fixed for wingrass as dep req's UNIX)

so those should be tested & then backported for 6.4.3.

the rest can wait until after the freeze and go in for 6.4.4.

[hamish]

non-harmless cases listed in comment:16 backported to relbr64 in r55725. testing still welcomed.
