Hi all,

i did get trac running with fcgid on apache in gentoo without thread and
mpm_prefork which works but was pretty slow on an pIII. same was with
mod_pyton. So I tested with compiling apache with mpm_worker and get
this message when trying fcgid again (mod_python works here too but also
slow):

Oops...

Trac detected an internal error:

(22, 'Invalid argument')

Traceback (most recent call last):

To run this configuration theres a script delivered in tracs svn:

---

import os
os.environ['TRAC_ENV']="/var/trac/master"
os.environ['PYTHON_EGG_CACHE']="var/tmp"

try:
    from trac.web import fcgi_frontend
    fcgi_frontend.run()
except SystemExit:
    raise
except Exception, e:
    print 'Content-Type: text/plain\r\n\r\n',
    print 'Oops...'
    print
    print 'Trac detected an internal error:'
    print
    print e
    print
    import traceback
    import StringIO
    tb = StringIO.StringIO()
    traceback.print_exc(file=tb)
    print tb.getvalue()
---


Has it something to do with threads?
I don't know if iam right here on this list. Perhaps better on trac's ?

my config:

fcgi-2.2
apache-2.2.6-r2
Trac-0.11dev_r6306-py2.5.egg
Python-2.5.1-r4


Regards, Gunnar
