Description:
Python's support for multithreaded programs has improved considerably over
the last few years with the advent of the "free-threaded" version of the language . But
testing multithreaded programs is notoriously difficult, because the
underlying host system determines the thread-execution ordering, which adds
an element of non-determinism. At PyCon US, Larry Hastings gave a talk ( YouTube video )
about his blanket project,
which is meant to provide mechanisms for deterministic testing of
multithreaded Python code.
