Hello Jason,

Thank you very much for your feedback.

We did update python31 on May 9th (and pushed to stable on the 26th)
with a fixed configure flag. This fix caused python31 to be build with
Unicode UCS4 rather than UCS2:

    https://bugs.launchpad.net/ius/+bug/779120

As you pointed out python31-mod_wsgi also needs to be rebuilt do to
these compile changes.

I have been able to reproduce the error you mentioned above with the
current version of python31-mod_wsgi:

   # rpm -q python31-mod_wsgi
   python31-mod_wsgi-3.3-1.ius.el5.x86_64

   # service httpd restart
   Stopping httpd:                                            [  OK  ]
   Starting httpd: httpd: Syntax error on line 210 of /etc/httpd/conf/httpd.conf: Syntax error on line 21 of 
   /etc/httpd/conf.d/python31-mod_wsgi.conf: Cannot load /etc/httpd/modules/python31-mod_wsgi.so into server: 
   /etc/httpd/modules/python31-mod_wsgi.so: undefined symbol: PyUnicodeUCS2_DecodeLatin1
                                                          [FAILED]

I then rebuilt python31-mod_wsgi against the current python31 package to
resolve the issue:

   # rpm -q python31-mod_wsgipython31-mod_wsgi-3.3-2.ius.el5.x86_64

   # service httpd restart
   Stopping httpd:                                            [FAILED]
   Starting httpd:                                            [  OK  ]

I will have this rebuilt package out to IUS stable here today.

Title:
  Critical apache/mod_wsgi failure on upgrade to python 3.1.3

Status in IUS Community Project:
  New

Bug description:
  Hello,
  (Centos 5, x86_64)

  Upon a code deployment this evening, apache failed to restart with
  this message:

  Starting httpd: httpd: Syntax error on line 55 of
  /etc/httpd/conf/httpd.conf: Syntax error on line 1 of
  /etc/httpd/conf.d/python31-mod_wsgi.conf: Cannot load
  /etc/httpd/modules/python31-mod_wsgi.so into server:
  /etc/httpd/modules/python31-mod_wsgi.so: undefined symbol:
  PyUnicodeUCS2_DecodeLatin1

  After some digging, I noticed that Python had been upgraded to 3.1.3
  just a couple days ago (in my case, via yum-cron):

  May 26 04:15:47 Updated: python31-3.1.3-2.ius.el5.x86_64
  May 26 04:15:47 Updated: python31-libs-3.1.3-2.ius.el5.x86_64

  I suspected that mod_wsgi was built against an outdated api/abi in
  python, so using mock, I rebuilt against python 3.1.3, installed that
  RPM, and everything works fine.

  I've attached my SRPM which increments the release and provides a note about the error.
  If anyone is in need of a temp hot-fix, the RPM can be found at: http://code.appcove.com/python31-mod_wsgi-3.3-2.ius.el5.x86_64.rpm

  Thanks!
