Subject Running Extern PHP Script
Date Wed, 23 Oct 2013 17:26:45 GMT
Hello All,
I am trying to run a PHP script, using this basic tutorial:
    http://wiki.apache.org/couchdb/ExternalProcesses

My test script is AMAZINGLY simple, as a tutorial to test with:
    <?php
    $line1 = trim(fgets(STDIN));
    fwrite(STDOUT, "{\"code\":200 , \"body\" : \"The script ran\" }\n");
    fflush(STDOUT);
    ?>

It runs from the command line just fine.


It runs from couch every *other* time.  That is when I press 'refresh' on the browser, it
goes between the proper output and an error.  (This tells me the INI is set up correctly)


I am running on a Raspberry Pi, if that make any difference.

I have tried terminating with both "\r\n"  and just "\n"  but it makes no difference.
The couch log is rather long, so I pasted the "reason for termination" below.  I don't know
what "noproc" means in the log.

Can anyone tell me what I have done wrong?  And why it is executing properly every *other*
time? 
Any advice would be appreciated.

-Scott Weber
