Attached patch changes signal.sigtimedwait() to retry if sigtimedwait() failed with EINTR and the signal handler didn't raise an exception. |

It looks like signal.sigwaitinfo() can also fail with InterruptedError. It should also be modified. |

signal_eintr.py: More complete patch, modify also signal.sigwaitinfo(). -- I don't think that other signal functions need to be modified to handle EINTR. POSIX manual pages: - "The pthread_sigmask() function shall not return an error code of [EINTR]." - "The pthread_kill() function shall not return an error code of [EINTR]." pause() fails with EINTR when it receives a signal, but signal.pause() doesn't raise InterruptedError in this case, it only returns None, because we expect a signal. I tested: signal.sigwait([]) doesn't fail with EINTR with a signal is received. No need to modify this function. On Linux, signal.set_wakeup_fd() doesn't fail with InterruptedError. |
