One information source not starting up properly

I've got a django information source that just refuses to load via Cherokee.
It loads fine if I type the exact command into the terminal (and pages are
accessible through Cherokee if it's running). It's very odd.

Connection: /websites/mysite-co-uk/sock
Interpreter: /websites/mysite-co-uk/manage.py runfcgi
workdir=/websites/mysite-co-uk/ maxspare=3 method=threaded protocol=scgi
socket=sock pidfile=pid

The server is running as the same user I log in as. I'm using similar
commands for other django websites (just changing the paths). Any idea's why
it's not launching?

If you don't know what it might be exactly, is there any way I can get a
look at what's exploding?

You could always launch cherokee-admin with the --debug parameter. Maybe
you'll see something there.

Not seeing anything.. at all. Just to confirm, I'm running: sudo
cherokee-admin -b -u --debug

Start cherokee-worker manually. And see if you get any console errors.
Alternatively use the trace functionality.

Re: One information source not starting up properly [In reply to]

Hmm reply-to-all wasn't working. Make sure you reply to the list people!

For the group, here's what I accidentally just sent to Christopher:

Right I created a script, based on the one above. It means my interpreters
are now just: /websites/launch <website-name> <thread-count>
For posterity, I'll include that at the bottom of this email.

Much nicer and it works for all my other django sites... But not this one
still! Same gig as before, if I launch it with this new script, cherokee
finds it. If I let it try to launch itself, it fails all over the place.

@Stefan: How do you mean trace? I ran cherokee-worker from a terminal and it
didn't display errors. Do I need to enable something else?

Here's my new launch file if anybody wants it:

#!/bin/sh

BASE=/websites
APP="$BASE/$1"

PIDFILE="$APP/pid"
SOCKET="$APP/sock"

if [ -f $PIDFILE ]; then
kill `cat -- $PIDFILE`
rm -f -- $PIDFILE
fi
if [ -f $SOCKET ]; then
rm -f -- $SOCKET
fi

cd $APP

/usr/bin/python2.6 manage.py runfcgi \
protocol=scgi \
method=threaded \
workdir=$APP \
socket=$SOCKET \
pidfile=$PIDFILE \
maxspare=$2

Hi Oli.
Look for the CHEROKEE_TRACE environment variable [1] and how to use it.

Did you actually access anything using that source?

Mmmmm... Maybe I'm saying something stupid but... are you sure that
"manage.py" has the executable bit set?

Not stupid; any suggestions are worth checking!

But yeah, it's executable. It also runs fine if I launch it directly (as the
same user as the cherokee-worker thread is running)

Yeah. I shut down cherokee (stop /etc/init.d/cherokee stop) and then ran
cherokee-worker with tracing.

All my sites were available (well with the exception of this problem one)
but nothing came from the trace. Does it trace to file? I thought it
outputted to terminal?

Re: One information source not starting up properly [In reply to]

I don't think that's stupid. Some of our wizards prepende 'python' to
the interpreter line, just for safety.
I've also seen a lot of Python scripts not beginning with the usual
'#!/usr/bin/env python' (instead they call a python binary on a
not_so_portable path). If Oli is using different platforms maybe this
could be the issue.

An then you went to the website?

The trace is to the terminal (if compiled with tracing).

Yes, my bet was the executable bit unset or the missing of
"#!/usr/bin/env python" line, because it doesn't make sense that other
scripts work only changing the paths... "manage.py" in the problematic
path should be different to the others.

DISCLAIMER: I don't know nothing about Django... O:)

Django creates the manage.py file when you create the project. The content
is the same across all my projects (inc working ones).

Yeah. I tried other working django sites. This broken site while broken and
this site when I ran the fcgi manually. All were as expected
(working-broken-working) but nothing was outputted as trace.

Indeed.

I didn't compile this so I don't know if tracing is enabled. If it's not,
perhaps cherokee aught to explode if you try and trace (instead of saying
it's tracing when it's not).

I disagree with the exploding parte ;)

You can check if it was compiled with tracing with the '-i' parameter.

# cherokee -i

Thanks Taher. It doesn't look like mine has tracing.

Re: One information source not starting up properly [In reply to]

Well I thought I had tested, but:

My site, as broken, lives in a directory like this:
/websites/mydomain-co-uk

I just copied it to:
/websites/mydomaincouk

And fixed up the cherokee settings to match and it WORKS! Woo!

So there's a bug in cherokee's mapping. I suspect it's misinterpreting the
socket location (which also had the dashes in).

Re: One information source not starting up properly [In reply to]

Great to know it is solved.
Could you log a bug for this so we don't forget to check it out?

Thanks ;)
