added getnewargs() to str.rs by zer0who · Pull Request #3811 · RustPython/RustPython
#3807 was recently merged, which changes how CI runs the test suites. Can you rebase your branch on a fresh copy of main? Once you've done that, feel free to run the following command:
cargo run --release --features ssl,jit -- -m test -j 1 -u all --slowest --fail-env-changed -v test_enum test_pickle test_pickletools test_unicode
(Of course, everything after the -v flag can be changed out with whatever tests you want. Or none at all, if you have plenty of time to spend.)
