Re: problem getting couchpy working on debian - {os_process_error, {exit_status,2}}

[Steve Ross]

Probably not the best place to get support on building couch but, I've found that this is the most useful way of building it:

https://github.com/iriscouch/build-couchdb

The only problem with using the link above is if you want couch to run as the current user and not require sudo you need to edit the build-couchdb/build/etc/init.d/couchdb shell script

and comment out (this removes the su )

#if test -n "$COUCHDB_USER"; then

#    if su $COUCHDB_USER -c "$command"; then

#        return $SCRIPT_OK

#    else

#        return $SCRIPT_ERROR

#    fi

#else

...

...

#fi

Hello,

I've just installed couchdb 1.2 on debian squeeze 6.0.5 and copied a small test database across from my OS X computer. The javascript view queries run correctly in futon. I've installed couchdb python and can import it in python:

>>> import couchdb

>>> print couchdb.__version__

0.8

Versions of python and erlang:  Python 2.6.6 and Erlang R15B02 (erts-5.9.2) .

I added python=/usr/bin/couchpy in the query_servers section of the configuration using futon.

In futon, I go to temporary view and see the python option, but when I try to run the default python view I get no response, and errors in the log file - {os_process_error, {exit_status,2}}

I tried saving the view, and it didn't change the problem.

There are a lot of the OS Process Errors and then this:

Can anyone suggest what I can try or look at to work out why it isn't working?

Hi Brenda!

Thanks for detailed info and sorry for late response!

But I'm wondering about problem. Looks like query server fails on message:

["reset",{"reduce_limit":true,"timeout":5000}]

Have you tried to pass it manually to couchpy? There should be next scene:

$ /usr/bin/couchpy
["reset",{"reduce_limit":true,"timeout":5000}]↵
true

or Python traceback instead. But I wonder why couchpy process dies
with exit status 2 - it should exit only with 0 or 1 status. Normally.

May you also enable debug logs? Just modify query server config value
to next one:

python=/usr/bin/couchpy --debug --log-file=/var/log/couchdb/couchpy.log

Will be there something interesting in logs?

Also, does JavaScript one works fine? But I'm not sure that this is
global problem...

Currently that's all what I have - I'd repeat all your steps, but
failed to reproduce such problem. Hoping that you could get more info
to help figure out where is the problem.
