Glance Client tool - getting 'Bad file descriptor' when calling GET image JSON schema

[Maty Grosz]

Hi,

When I am running Glance Client tool against glance service using the following command:

> glance --debug --os-image-api-version 2 image-list

I get the followng output:

curl -i -X GET -H 'X-Auth-Token: rO0ABXc4ACAyYzlkYTk4ZDQwZGVmNWU2MDE0MGZjZDI0OThiMzk3MQAGbWdyb3N6AAQzMDQ3AAABQP0JOAs' -H 'Content-Type: application/json' -H 'User-Agent: python-glanceclient' -k https://cb.alucloud.local/al-openstack/v2/schemas/image
(9, 'Bad file descriptor')

--------------------------------------------------------------------------------------------------------------------------------------------

*BUT* when I am running just the exact curl command you see in the debug log

> curl -i -X GET -H 'X-Auth-Token: rO0ABXc4ACAyYzlkYTk4ZDQwZGVmNWU2MDE0MGZjZDI0OThiMzk3MQAGbWdyb3N6AAQzMDQ3AAABQP0JOAs' -H 'Content-Type: application/json' -H 'User-Agent: python-glanceclient' -k https://cb.alucloud.local/al-openstack/v2/schemas/image

I get what am I expecting to get - the JSON schema:

HTTP/1.1 200 OK

Content-Type: application/json
Content-Length: 4958

Can you try a curl command similar to the above but changing "v2/schemas/image" to "v2/images", please?

I have upgraded the python-glanceclient to v0.11.0.
Now, I get a whole new different behavior... I get 404 - Item not found, and the reason is as followes:

In file glanceclient/common/http.py, line #192:

---------------------------------------------------------
if self.endpoint_path:
        url = urlparse.urljoin(self.endpoint_path, url)
conn_url = urlparse.urlsplit(url).geturl()
---------------------------------------------------------

instead of calling urlparse.urljoin, just replace it with
        url = self.endpoint_path + url

And everything is happy!

I, in my application, expose OpenStack Image APIs (v2), using the following URI structure:

http://<host>:<port>/some/path/prefix/v2/schemas/image

If I run glance client image-list command using the source code, with the bug -
> the value of self.endpoint_path is /some/path/prefix
> the value of url is /v2/schemas/image,
*but*
> the value of urlparse.urljoin(self.endpoint_path, url) is *JUST* /v2/schemas/image...

and thus, the value of conn_url is http://<host>:<port>/v2/schemas/image - which, of course, I don't listen to and thus get 404.

Need a fix for that.

Thanks,

Maty.
