Discriminator causes stackoverflow #503

Open aavanzyl opened 7 years ago

aavanzyl commented 7 years ago

Hi

So when using a discriminator I get a stack overflow. You can only see this when running in verbose.

Swagger Version: 2.2.3 Java Version: 1.8

I generate Java API code from this, but the failure happens in the parsing of the swagger document.

My Swagger: 

Offer:
    type: object
    # Used in the parent object to distinguish which derived object is used.
    discriminator: offerType
    required:
      - "offerType"
      - "id"
      - "name"
      - "value"
      - "productType"
    properties:
      offerType:
        type: string
        example: "LimitedOffer"
      id:
        description: "Used internally in the database. Use this value for the delete endpoint."
        type: integer
        format: int64
        minimum: 1
      name:
        description: "The name of the product."
        type: string
        maxLength: 100
        example: "Samsung Galaxy S7"
      productType:
        $ref: "#/definitions/ProductType"
      description:
        description: "A description of the product offer."
        type: string
        maxLength: 200
        example: "The Galaxy S7's hardware design is largely identical to that of the S6; it retains its metal and glass chassis, but with refinements such as a squarer home button, and a thinner protrusion for the camera. Both models are available in black and gold colors; white, pink, and silver versions are available depending on market."
      inStock:
        description: "Is the product ex stock."
        type: boolean
        example: "true"
      value:
        description: "The value of points required to buy this offer."
        type: integer
        format: int64
        minimum: 0
        example: "10000"
      discountRate:
        description: "Optional percentage discount on this offer."
        type: number
        format: double
        minimum: 0
        maximum: 100
        example: 25.0
      expires:
        description: "Date on which the offer expires, and is no longer available."
        type: string
        format: date-time
        example: "2016-12-25T00:00:00.000+02:00"
      image:
        description: "Image base64 encoded data of the product on offer."
        type: string
        format: byte
        maxLength: 10000
        example: "iVBORw0KGgoAAAANSUhEUgAAAAYAAAAGCAMAAADXEh96AAAAA1BMVEX/8gA/aIoIAAAAC0lEQVR4AWMgGgAAACoAAdrhCd0AAAAASUVORK5CYII="

# Example of inheritance
  LimitedOffer:
    allOf:
    - $ref: '#/definitions/Offer'
    - type: object
      required:
        - "duration"
      properties:
        duration:
          description: "How long is this limited offer valid."
          type: string
          format: date-time
          example: "2016-12-25T00:00:00.000+02:00"
        availableFrom:
          description: "From when is the offer available."
          type: string
          format: date
          example: "2016-12-24"

The Stack Trace I get:

Swagger is not a specific project, it's a collection of those. Which one are you referring to? 2.2.3 is the version of what?

aavanzyl commented 7 years ago

Hi

Using the Swagger Codegen. 

<dependency>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-codegen</artifactId>
    <version>2.2.3</version>
</dependency>

Same issue with swagger-codegen-cli-2.3.1

I'm seeing the same in 3.0.20.

piurafunk commented 1 year ago

I found a different issue before this one, figured I'd link the 2, as they seem related: https://github.com/swagger-api/swagger-codegen/issues/10851

My opinion is to move off Swagger tools and onto OpenAPI tools.
