Perhaps surprisingly, all the webkitpy tests do appear to pass on Python 3.13, but we get yet more deprecation warnings. 2069672 1 webkit-bug-importer 2024-10-21 15:04:17 -0700 <rdar://problem/138352675> 2069691 2 gsnedders 2024-10-21 16:00:52 -0700 Running more than just webkitpy, one discovers webkitflaskpy depends on hiredis-3.0.0 and lupa-2.2, neither of which have 3.13 wheels. But again, with them installed from source, we do actually pass all tests on Python 3.13. 2069694 3 gsnedders 2024-10-21 16:08:03 -0700 So I think the main thing necessary for 3.13 support is upgrading pyfakefs to avoid https://github.com/pytest-dev/pyfakefs/issues/1017, and then we're gonna need to bump versions of the other dependencies or allow them to install (compile) from source. 2069698 4 gsnedders 2024-10-21 16:11:55 -0700 Oh, and I forgot to mention "upgrading cffi", which is also necessary.
