Certificates API hangs if request body is omitted

[Jason Dunsmore]

Calling the "PATCH /certificates/<cluster-id>" API with an empty body works:

$ curl -g -i -X PATCH http://localhost:9511/v1/certificates/4230cc5c-39da-42bf-a15e-436ee47e12ee -H "OpenStack-API-Version: container-infra latest" -H "X-Auth-Token: $(openstack token issue -f value | sed -n 2p)" -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: None" -d '{}'
HTTP/1.0 400 Bad Request
[...]

But when "-d '{}'" is omitted from the curl command, the API hangs:

$ curl -g -i -X PATCH http://localhost:9511/v1/certificates/4230cc5c-39da-42bf-a15e-436ee47e12ee -H "OpenStack-API-Version: container-infra latest" -H "X-Auth-Token: $(openstack token issue -f value | sed -n 2p)" -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: None"

Calls to pecan.request.body cause the API to hang.

This is probably a pecan bug. I've submitted a Github Issue in the pecan project https://github.com/pecan/pecan/issues/87

[Jason Dunsmore (jasondunsmore)]

It's an upstream bug https://github.com/Pylons/webob/issues/233 fixed by https://github.com/Pylons/webob/pull/283 which is in WebOb>=1.7.0

Change to global requirements (https://review.openstack.org/#/c/425950/) will have to wait until after feature freeze. In the meantime, we can either pass an empty string as the request body "-d ''" or pass the header "Content-Length: 0".

this was merged in requirements, closing

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/requirements 1.1.0 release.
