This is testing the code which specifically supports working around the unfortunate behavior of CPython to write a .py source file name into the .pyc files it generates and then trust that it is correct in various places. If source files are renamed, .pyc files may not be regenerated, but they will contain incorrect filenames. rrrrs module.pyrr)moduler)invalidate_cachesstwisted_renamed_helpertwisted_renamed_helperr N)r rrrrrrrrrgrrrrrrr& importlibr ImportErrormoveTosiblingrrrr!r"r#)rrrrrs rtest_renamedSourcez%FlushWarningsTests.test_renamedSourceDs4;;==//8899?? %    n%%00555 l##..

In Python 3.10 PEP 626 introduced byte-code change such that the last line of a function wasn't always associated with the last byte-code.
