[Python 3.7] Maven generation api 3.0.9 #9546
Comments

I suggest that you post your API spec so the developers can try to reproduce the problem. |
|
Sorry, but i can't. My company refuse to make the code public. |
|
I have the same issue with 3.0.9 and 3.0.10 - 3.0.8 works. The issue seems to be in https://github.com/swagger-api/swagger-codegen-generators |
|
I've got the more or less same issue using the 3.0.10 swagger-codegen-cli docker image. It doesn't depend if i choose spring or python as target language. The OpenAPI3 spec i'm using is a converted OData CSDL from our internal CMDB. Rather largish - json file is 8mb. There are many linked resources (Computers have Adapters, Adapters have Computers, ...) Unfortunatly I can't provide the OpenAPI3 spec and I failed to create a reproducer with Petstore. :-( Generate completes successfully with swagger-codgen-cli 3.0.8 - but Python code is invalid (which i think is fixed with 3.0.10). |
|
hello guys, working on this right now. |
|
@HugoMario Could you provide a jar that prints out the schema and the property that the I was able to build swagger-codgen with run-in-docker.sh but I have no clue how to integrate such a change from dependent repo. |
|
@HugoMario I came to the conclusion, that the problem is the recursive function: my spec got 1527 schemas with 14820 properties. And everything is heavily linked. |
|
@HugoMario managed to convert the CSDL with OpenAPI.NET.OData to OpenAPI3. swagger-codegen then exited successfully. :-) but the client is still not useable. But this is another issue. |

hi @vinzent, thanks for updates, checking issue i found a way to reproduce it too, in a scenario when we find circular references i.e: Category:
type: object
properties:
id:
type: integer
format: int64
pet:
$ref: '#/components/schemas/Pet'
Pet:
type: object
properties:
id:
type: integer
format: int64
category:
$ref: '#/components/schemas/Category'the issue is triggered, i guess it's the same if there are circular reference among three or more schemas. |

Similar issue that only occurs on version 3.0.9 and 3.0.10 but is fine on 3.0.8 (not using Python but Java but that shouldn't make a difference?): Exception in thread "main" java.lang.StackOverflowError

I added the following warning before this invocation (in the external module): logger.warn("Recursively resolving schema for " + propName.toString());and the schema above produced the following output, with the warnings repeated recursively, as expected, until the stack overflow: |

@HugoMario - I've created a PR to address this in the swagger-codegen-generators repo. |
|
hi @scottydawg, yes, i saw your PR thanks a lot !!, i'll add feedback there |
|
hello guys PR's swagger-codegen-generators#431 and swagger-codegen-generators#432 have been added in order to fix this issue. Can you please check if it works for you now? you can use this file with command: |

I successfully ran this against my schema without the stack overflow. 👍 |

Hello,
I generate my APIs in python with maven. I use the version 3.0.8 of swagger-codegen-maven-plugin. But python is an experimental moud and i have some error about Thread can't be created (maybe their are not closed) and MemoryError. So i want to use the version 3.0.9, with hope to not find the same errors.
But impossible to build my APIs, see below:

ERROR OUTPUT
Can you help me please ? :)
