[New-bugs-announce] [issue30807] setitimer() can disable timer by mistake

[Antoine Pitrou]

New submission from Antoine Pitrou:

The C setitimer() function supports intervals with microsecond resolution.  However, Python's setitimer() takes a float and then converts it to a C `struct timeval`, which can round down to zero.  The consequence is that the timer is disabled (timeval == {0,0}) while the user asked for a one microsecond timeout.
