Scope

It should be able to query all cm handles with a given set of public cm handle properties.

Requirements

  • We want all cm-Handles where both things are true.
  • If name is empty silently ignore, if value is empty (edge case test?)
  • Those properties also need to exist.
  • If query body does not follow supported structure return 400.
  • Empty query will return all cm-Handles.

A/C:

  1. Demo - with "and" behavior
  2. CI Test - two attributes

5Should search be case sensitive?

depend on CPSPath functionality - may be case-sensitive

https://docs.onap.org/projects/onap-cps/en/latest/cps-path.html

Yes, that is the currently implement as such CpsPath type query. Given it is mostly machine-to-machine type queries this is good enough and performs better
6What format should the response take?

We have two options currently:


  1. Return List<String>
Code Block
languageyml
[
    "cmHandle1",
    "cmHandle2",
    ...,
    "cmHandleN"
]


2. Return CM Handle Objects

    1. Already defined in CPS
    2. <Example Pending>

Contact Tony Finnerty & kieran mccarthy regarding this.
Tony Finnerty Has no opinion on this matter

It has been decided to implement this using a list of cm handles
7what if we have valid entries and one entry  is empty?

We would return all cm handles and others that match would be included in this list anyway.

→ To avoid this should we first check the entries int map for empty entries as further processing is unnecessary in this case.

Discussed with Toine Siebelink and implementation changes are required for handling edges cases. we will handle empty and unknown properties separately.

8

Regarding empty/missing property in request

e.g.

{

    "publicCmHandleProperties": {
        """doesnt matter "
    }
}

Do we want to throw an exception if there is an empty property?

Do we silently ignore them and move on?

should we send two lists back... one with matching cm handles and one with those that failed processing?

We will throw a DataValidationException if an entry contains an empty property

CPS stores Integers as Strings.

Given the public properties below

Code Block
languageyml
{
    "cmHandle": "Bookstore6",
    publicCmHandleProperties": {
        "color": 12345
        }
}, {
    "cmHandle": "Bookstore7",
    "publicCmHandleProperties": {
        "color": "12345"
        }
}


When stored in CPS Integers are stored as Strings.

xpathattributes

/dmi-registry/cm-handles[@id='Bookstore6']/public-properties[@name='color']

{"name": "color", "value": "12345"}
/dmi-registry/cm-handles[@id='Bookstore7']/public-properties[@name='color']{"name": "color", "value": "12345"}

Therefore the two requests below return both cm handles regardless of wanting Integer or String.
