Bug Description

Backport to MOS 7 - Kilo


Detailed bug description:

Tried creating template https://github.com/openstack/heat-templates/blob/master/hot/hello_world.yaml and since nova could not succeed, ResourceFailure was raised and stack went to CREATE FAILED state.

Now If we modify one of the parameters consumed by template, lets say 'key_name' to 'keyname', and perform an update, and ResourceFailure again occurs stack will be moved to UPDATE FAILED state.

After the above operations heat stack-list breaks with error:
The Parameter (keyname) was not provided

Steps to reproduce:

Modify parameters in template and perform a stack update. Then performn a stack-list command.

Expected results:

Stack-list should output.

Actual result:

You get a message such as:

The Parameter (parameter changed) was not provided




Update parameter back to original parameter


Unable to use heat stack-list via CLI or Horizon after update is made.

Fix stack-list after failed update

When a update is being performed, the existing template is updated
incrementally as resources change. Now if update fails, template will
have mix of resources from existing and new template. Hence we need to
ensure we have the user params of both.
