[Python-modules-team] Bug#758035: libapache2-mod-wsgi: WSGIDaemonProcess python-path and home fails

[Sebastian Rittau]

Package: libapache2-mod-wsgi
Version: 4.2.7-1
Severity: important

Since upgrading to mod-wsgi 4.2, even a simple WSGI script will cause an
Internal Server Error when the python-path and home arguments to
WSGIDaemonProcess are used in conjunction with WSGIProcessGroup.

Consider the following script:

    def application(env, sr):
        sr("200 OK", [])
        return "XXX"

and the following WSGI configuration

    WSGIDaemonProcess foo home=/tmp python-path=/tmp
    WSGIProcessGroup foo

This will cause an Internal Server Error with the following log entry:

    [Wed Aug 13 19:28:05.889392 2014] [wsgi:error] [pid 25594] [client 127.0.0.1:36384] Truncated or oversized response headers received from daemon process 'foo': /tmp/test.wsgi

Removing either the WSGIDaemonProcess, the python-path, or the home directive
will fix it.
