Bug description:
threading.Barrier at no point checks for validparties.parties, of a negative value, or invalid type hang indefinitely on.wait(). This behavior is inconsistent from the behavior of any otherthreading primitives, which either conduct sanity checks on args during initialization, or fail at some point in their execution.
Steps to reproduce:
fromthreadingimportBarrier# negativebarrier=Barrier(-1)# <threading.Barrier at 0x10aa789b0: waiters=0/-1>barrier.wait()# invalid type stringbarrier=Barrier("test")# <threading.Barrier at 0x10ae64980: waiters=0/test>barrier.wait()# invalid type floatbarrier=Barrier(0.5)# <threading.Barrier at 0x10aa7a570: waiters=0/0.5>barrier.wait()# invalid type objectbarrier=Barrier(object())# <threading.Barrier at 0x10ae4f500: waiters=0/<object object at 0x10a878730>>barrier.wait()
