  ============
  SRU TEMPLATE
  ============

  [Impact]

  The issue impact stack creation workflows where swift signals are
  used. There is no workaround for the issue other than not using swift
  signals. The fix is a conditional one-liner that performs a type-check
  before running the code change.

  [TestCase]

  1. Setting up env
  1a. Deploy an environment with ceph-rgw and heat
  1b. Make sure rgw-swift-versioning-enabled=true

  2. Reproducing the bug

  2a. Create a stack using the following template:

  ---
  heat_template_version: 2021-04-16

  resources:
    signal:
      type: OS::Heat::SwiftSignal
      properties:
        handle: {get_resource: signal_handle}
        timeout: 300

    signal_handle:
      type: OS::Heat::SwiftSignalHandle

    instance_port:
      type: OS::Neutron::Port
      properties:
        network: private
        fixed_ips:
          - subnet_id: private_subnet

    the_server:
      type: OS::Nova::Server
      properties:
        name: test
        image: cirros2
        flavor: m1.cirros
        networks:
          - port: { get_resource: instance_port }
        user_data_format: RAW
        user_data:
          str_replace:
            template: |
              #!/bin/sh

              # Simple success signal
              wc_notify --data-binary '{"status": "SUCCESS"}'
            params:
              wc_notify: { get_attr: [signal_handle, curl_cli] }

  2b. Use command "openstack stack create test -t template.yaml

  2c. Wait for stack creation to fail using command "openstack stack
  list"

  2d. Once failed, display the details using command "openstack stack
  show test"

  2e. Confirm error with the message:

  | stack_status_reason   | Resource CREATE failed: Error:
  resources.signal: Failed to parse JSON data: b'in progress'

  3. Cleanup not really needed

  4. Install package that contains the fixed code

  5. Confirming fix: Repeat steps 2a-2e and confirm stack creation is
  either successful or fails with a different message for another reason

  [Regression Potential]

  Since there is a type-check included in the fix, the regression
  potential is minimal, as if the condition is not fulfilled, then the
  original code is run.
