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.

Ah, interesting.
I don't speak Python, but it didn't look like that script had any loop in it.
That might be a good thing to mention in the "Common Pitfalls" section
Thanks.

Try the following modification to your test script. It loops the STDIN
input as Robert stated.
<?php
while($line1 = trim(fgets(STDIN))) {
fwrite(STDOUT, "{\"code\":200 , \"body\" : \"The script ran\" }\n");
fflush(STDOUT);
}
?>
