calling a script within a script failing on Windows XP

[hamish]

Hi,

We're trying to run v.random.cover(.sh) from grass6 addons on Windows XP using the standard 6.4.2-2 prebuilt binaries. That script calls v.report(.sh), but v.report fails. "g.parser has encountered a problem and needs to close." and v.report exits with a non-zero error code.

turning debug to level 1 I see "ret = 1" from the G_spawn() command.

Running the exact same v.report command from the msys command line works fine.

I'd note v.report sends data to both stderr and stdout, but that's all after the g.parser call.

I seem to recall a problem long ago where in wingrass a script calling another script didn't work.

Running which v.report from the msys command prompt shows C:/Program Files/GRASS 6.4.2/scripts, not the wrapper .bat file in $GISBASE/bin/. maybe it doesn't like $0 != what gets run on the second g.parser pass??

I'm not sure what to try to debug next.

thanks, Hamish

ps- we were also unable to download any of the addons directly with the gui extension tool, although the zip files seem ok on the server. Is it working for anyone with those 6.4.2-2 binaries?

[hamish]

oh yeah, one more minor problem: the help page in the extension .zip file was localized to the server's LANG setting :)

sort of #580, but not exactly.

I can confirm that it's calling any shell script from within another script, not just v.report. bumping priority

e.g. adding this to a script triggers it too:

g.manual -m dummy

should be fixed now for 6.4.3svn. Martin

bumping to blocker. we need to fix this ASAP as it takes out a bunch of the scripts, including many of the v.db.* ones.

thanks, Hamish

It seems to me that shell scripts don't work only if there are installed as AddOns. I think it's caused by the fact that shell script and bat script are placed in the same directory. It's result of your wish [1] which required extra hacking on g.extension side (it was the bad idea from POV) and moreover produced this blocker. It would be nice to simplify things and to complicated them when it's really not necessary. I hope that it was fixed in r53428 in G65. Please could you try the next snapshot, at least v.random.cover seems to work for me.

this ticket was about shell-scripts; maybe following it's worth for an extra ticket?:

there are some very nice python-based-script-addons for grass6.x, like the inter-dependent r.basin-, r.ipso-, r.wf-scripts (and others).

the pyhton addon-sscripts (r.basin.py, etc.) are stored in C:\Users\XXXX\AppData\Roaming\GRASS6\addons, whereas the related bat-files (r.basin.py.bat) are in C:\Users\XXXX\AppData\Roaming\GRASS6\addons\bin.

the content of the bat-files are e.g.

@"%GRASS_SH%" "%GISBASE%/scripts/r.basin.py" %*

in windows #!/usr/bin/env python isn't recognized, so "%GRASS_SH%" should be changed to "%GRASS_PYTHON%"

but changing this manually, r.basin calling r.ipso/r.wf isn't really working.

AFAIK python addons-scripts aren't at the moment officially supported in grass6.x (working out of the box in linux, but not in windows), although it would be nice if such peculiar scripts would also be available in windows.
