Maximum semantic analysis iteration count reached error with django-stubs 5.0.3 & 5.0.4

Bug report

What's wrong

When running django-stubs 5.0.2, mypy goes through without error. But when updating django-stubs to 5.0.3, I’m getting the following error:
error: INTERNAL ERROR: maximum semantic analysis iteration count reached.

The traceback is huge, and not really helping, so my next step is to have a minimal reproduction, but I wanted to raise the bug in case someone else is running into this as well. I’ll also try to review what’s happening between the 2 versions to understand where the issue can be.

System information

• OS: Linux 6.10.5
• python version:
• django version: 5.0.9 (but same error with 5.1.1)
• mypy version: 1.11.2 (but same error with 1.10.1)
• django-stubs version: 5.0.3
• django-stubs-ext version: 5.0.3

It works fine with:

• django version 5.1.1
• mypy version 1.11.2
• django-stubs version 5.0.2
• django-stubs-ext version 5.0.2

If I understand you correctly you can reproduce with the code you have? Essentially that your code triggers a regression between the versions?

Could you perhaps run a git bisect between 5.0.2 and 5.0.3 to pin point which commit introduced the issue?

You could also try out master to see if the issue exists there too.

Correct. My next plan was indeed to do a git bisect but didn’t have plan to complete. Will do (hopefully) today.
