clingo-5.3.0-6.fc32 failed to rebuild with Python 3.8. See https://koji.fedoraproject.org/koji/buildinfo?buildID=1358350 The error is: BUILDSTDERR: /builddir/build/BUILD/clingo-5.3.0/libpyclingo/pyclingo.cc:1125:14: error: cannot convert 'std::nullptr_t' to 'Py_ssize_t' {aka 'long int'} in initialization In Python 3.8, the reserved "tp_print" slot was changed from a function pointer to a number, `Py_ssize_t tp_vectorcall_offset`. In C, there is no "nullptr"; either a 0 or NULL casts automatically to both pointers and numbers. Please use 0 instead of "nullptr" in the slot to be source-compatible both with Python 3.8 and previous versions. See this as an example PR: https://github.com/YafaRay/Core/pull/114 This issue is blocking the Python 3.8 rebuilds. If this package won't build with 3.8, it won't be installable, along with all its dependent packages, after the side tag is merged. Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well. The coordinated rebuild of Python 3.8 has started in the `f32-python` side tag. If you figure out how to rebuild this package, please don't rebuild it in regular rawhide, but use the side tag instead: on branch master: $ fedpkg build --target=f32-python To wait for a build to show up in the side tag, do: $ koji wait-repo f32-python --build=<nvr> Where <nvr> is name-version-release of the source package, e.g. python-foo-1.1-2.fc32. An updated mock config is posted at: http://copr.fedorainfracloud.org/coprs/g/python/python3.8/ Thanks. Let us know if you need up to date info, or if you have any questions.
The f32-python side tag has been merged. In order to rebuild the package, do it in regular rawhide, but please wait until python3-3.8 is tagged: $ koji wait-repo f32-build --build python3-3.8.0~b3-3.fc32 If your built already started in f32-python, after it is finished, please tag it to rawhide with: $ koji tag-build f32-pending <nvr> For example: $ koji tag-build f32-pending libreoffice-6.3.0.4-3.fc32 Thanks! (This comment is mass posted to all bugzillas blocking the PYTHON38 tracking bug.)
(Python 3.8 has landed in the rawhide buildroot.)
