priors not auto-generated

[dlebauer]

related to github #19 :

PEcAn packages are installed on ebi-forecast using the following code:

export R_LIBS_USER="/usr/local/R-2.15/lib64/R/library"
wget https://github.com/PecanProject/pecan/archive/v1.3.2.tar.gz
tar -xvf v1.3.2.tar.gz
./pecan/scripts/build.sh

But the image regeneration still does not work.

I delete the images, touch restart.txt, and relaod. But the pictures do not show up.

rm /usr/loca/ebi/images/prev/*.png
touch /usr/local/ebi/tmp/restart.txt
## refresh browser
## expect images

to get the images back for now:

rsync -routi pecandev:/usr/local/ebi/public/images/prev/*.png /usr/local/ebi/public/images/prev/

@gsrohde how can I send the output from Line 82 in app/controllers/priors_controller.rb to a log file? Is there somewhere that catches stderr (or a way we can get all of this sent to a temporary log file, or somewhere else that I can watch it?

This is the answer that @robkooper found: http://stackoverflow.com/a/1563625/199217

Probably the easiest thing to do is copy STDERR to STDOUT and then replace "system" with backticks:

err_output = `R --vanilla --args #{imgfile} #{distname} #{aparam} #{bparam} #{n} < script/previewhelp.R 2>&1`
logger.info(err_output)

This will send the STDERR (and STDOUT as well) from the command to the Rails logger. (Send STDOUT to /dev/null if you don't want it.)

Use logger.debug in place of logger.info if you don't want the logging to happen in the production environment.

Also: Be sure all the interpolated variables aren't something the casual user can tamper with!
