Description Michael Mráka 2010-02-07 20:04:55 UTC 
Description of problem:
Doing spacewalk 0.8 release test I failed to register F12 and F11 clients to F12 server.
Registering to F12 client to RHEL5 server or RHEL5 client to F12 server works.

Version-Release number of selected component (if applicable):
server:
spacewalk-backend-0.8.43-1.fc12.noarch
client:
yum-rhn-plugin-0.8.5-1.fc11.noarch
rhn-client-tools-0.8.10-1.fc11.i586

How reproducible:
always

Steps to Reproduce:
1. setup spacewalk server on Fedora 12
2. register Fedora 12 client to the server
3.
  
Actual results:
# rhnreg_ks --server http://hp-z200-05.rhts.eng.bos.redhat.com/XMLRPC --activationkey 1-fedora11-i386 --force

On server side:
[root@hp-z200-05 ~]# tail -f /var/log/rhn/rhn_server_xmlrpc.log
2010/02/07 14:54:03 -04:00 7270 10.10.76.130: xmlrpc/registration._normalize_packages('ERROR', 'Invalid package spec for extended_profile >= 2', <type 'list'>, 'len = 4')

Expected results:
registration works

Additional info:
Server capabilities received on client from F12 server:
 {'xmlrpc.login.extra_data': {'version': '1', 'value': '1'}}
while from RHEL5 server:
{'registration.finish_message': {'version': '1', 'value': '1'}, 'registration.remaining_subscriptions': {'version': '1', 'value': '1'}, 'registration.update_contact_info': {'version': '1', 'value': '1'}, 'applet.has_base_channel': {'version': '1', 'value': '1'}, 'registration.smbios': {'version': '1', 'value': '1'}, 'registration.extended_update_support': {'version': '1', 'value': '1'}, 'registration.register_osad': {'version': '1', 'value': '1'}, 'rhncfg.content.base64_decode': {'version': '1', 'value': '1'}, 'rhncfg.filetype.directory': {'version': '1', 'value': '1'}, 'registration.delta_packages': {'version': '1', 'value': '1'}, 'xmlrpc.packages.extended_profile': {'version': '1-2', 'value': '1'}, 'xmlrpc.login.extra_data': {'version': '1', 'value': '1'}}

Registration fails 'cause of missing 'xmlrpc.packages.extended_profile': {'version': '1-2', 'value': '1'}.
{'xmlrpc.login.extra_data': {'version': '1', 'value': '1'}}
Comment 1 Michael Mráka 2010-02-10 14:53:17 UTC 
So I added log messages to apacheRequest.response() function (lines 351 amd 359 of server/apacheRequest.py) and the difference is:

RHEL5 server:

Comment 2 Michael Mráka 2010-02-10 22:17:51 UTC 
On RHEL5 (mod_python) type(self.req.headers_out) is mp_table, while on F12 (mod_wsgi) type(self.req.headers_out) is  WsgiDict (which is subclass of dict).
mp_table allows several items with the same key while dict not.
