httplib throw "TypeError: an integer is required" when run quantum on fedora 16

Are you sure the config between the two setups is exactly the same? It
seems like the python httplib is passing the underlying socket lib a value
that is not an int. Perhaps the port number or the timeout? Did you
change the default for either of these? Perhaps you specified it as a
string, not as an int?

hi dan, I can ensure it is exactly the same between the two setups because I do them by hand rather than devstack script.
and I aslo debug line 185 " c.request(method, action, body, headers)" of $nova/nova/network/quantum/client.py in both fedora and ubuntu.
I found the input parameters are both same , but that line throw error on fedora.
I feel it seems that some upstream problem of httplib, but I'm not sure.

now I have successfully run the openvswitch plugin + quantum and linuxbridge plugin + quantum on ubuntu server step by step.
but still failed to run quantum on fedora 16 and redhat due to above problem.

hi dan, thank you so much for the reply, I'am not running diablo nova, I run latest nova by git. and I update the code every day.

sorry, i missed the first log you posted. This is an error way down in the socket library. My best guess is that either the port or the ip address you are specifying for the quantum server are incorrect (perhaps they are strings when they should be integers?)

Perhaps try to print them out in the do_request method of nova/network/quantum/client.py .

Another possibility? are you trying to use SSL?

hi dan, I carefully debug it again, exception "TypeError: an integer is required" was throwed from following method in $nova/nova/network/quantum/client.py

 c.request(method, action, body, headers)

bellow are some debug infos from eclipse, and following connection type "httplib.HTTPConnection" shows that I haven't use SSL.

Globals Global variables
action unicode: /v1.1/tenants/986a58e77d8c49da9b4ff0dd1e823f0f/networks/7e32a6c6-c9b4-4ef0-8f30-472ea02dcdec.json
body NoneType: None
c HTTPConnection: <httplib.HTTPConnection instance at 0x67f1560>
certs dict: {}
connection_type httplib.HTTPConnection
headers dict: {'Content-Type': 'application/json'}
method str: GET
params NoneType: None
self Client: <nova.network.quantum.client.Client object at 0x532ec90>

if we use ubuntu, above method will be ok, and all input parameters are all same.

and as you said "It looks like this is an error being returned by nova, not quantum.", indeed I found out GET reqeust hasn't been send to quantum api by httplib, httplib connection was lost, so it seems that some upstream problem of httplib.

Thanks dan wendlandt, that solved my question.

dan, very thank you , I have fixed this issue by your good hint, the reason is as you said, nova is pass host value that is not a int,
i will fire a bug for nova later, thanks.
