[New-bugs-announce] [issue15320] thread-safety issue in regrtest.main()

[Chris Jerdonek]

New submission from Chris Jerdonek <chris.jerdonek at gmail.com>:

My understanding is that generators are not thread-safe.  For example, see

http://stackoverflow.com/a/1131458/262819

However, regrtest.main() seems to access a generator from multiple threads when run in multiprocess mode:

def work():
    # A worker thread.
    try:
        while True:
            try:
                test, args_tuple = next(pending)
            except StopIteration:
                output.put((None, None, None, None))
                return
