Tal Liron created ARIA-271:
------------------------------
Summary: Parameter.value should verify the type of an evaluation
Key: ARIA-271
URL: https://issues.apache.org/jira/browse/ARIA-271
Project: AriaTosca
Issue Type: Story
Reporter: Tal Liron
Currently, it is possible to have a parameter with an intrinsic function that
return a type which is different from what the parameter has been configured
for. Example:
{code}
node_types:
WebApp:
derived_from: tosca.nodes.WebApplication
properties:
port:
type: integer
interfaces:
Standard:
start:
inputs:
arg1:
type: string
topology_template:
node_templates:
web_app:
type: WebApp
properties:
port: 9090
interfaces:
Standard:
start: scripts/start.sh
inputs:
arg1: { get_property: [ SELF, port ] }
{code}
This can lead to subtle errors. In the above, arg1 is a string, but the
{{get_property}} function returns an int. No error is currently reported. (In
many cases Python will coerce the value dynamically, but in some cases it may
not.)
