Package: src:parso Version: 0.8.7-1 User: [email protected] Usertags: python3.15 Tags: patch
Hi! While rebuilding the python related packages against the python version 3.15rc1 we found that parso fails to build from source [1]. Python 3.15 changed some of the texts in the exception messages and parso tests rely on the exact wordings. Upstream already has fixed these issues and I'm attaching the upstream patches that we used in the sandbox. Please consider applying these patches to fix the compatibility with python 3.15.
