Package: src:ttconv Version: 1.2.2-1 User: [email protected] Usertags: python3.15 Control: forwarded -1 https://github.com/sandflow/ttconv/pull/544
¡Hola! While rebuilding packages against python 3.15 we found that ttconv produces some errors when used against it. The packages fails to build from source [0]. Seems that the attribute _MISSING_TYPE from dataclasses is used and it doesn't exists (at least) in python3.15. To fix it we should use MISSING instead of _MISSING_TYPE. I'm attaching a patch that fix this issue.
