[issue22015] C signal handler doesn't save/restore errno

STINNER Victor added the comment: Ooops, I looked at the wrong function. signal_handler() saves/restores errno. trip_signal() is a function called by signal_handler(). The code is correct. -- resolution: -> not a bug status: open -> closed ___ Pytho

[issue22015] C signal handler doesn't save/restore errno

New submission from STINNER Victor: The signal module has a wakefd feature which calls write(fd) in a signal handler, but the signal handler replaces errno without saving/restoring it. See "Practice 4" in this article: http://www.ibm.com/developerworks/linux/library/l-reent/index.html Attached
