Description: …575) Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some reserved signal numbers between 1 and NSIG. The range(1, NSIG) idiom is commonly used to select all signals for blocking with pthread_sigmask. So we ignore the sigaddset() return value until we expose sigfillset() to provide a better idiom. (cherry picked from commit 25038ec) Co-authored-by: Antoine Pitrou pitrou@free.fr https://bugs.python.org/issue33329
