https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214987 Bug ID: 214987 Summary: updating EVFILT_TIMER kqueue events doesn't work Product: Base System Version: 11.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: bwelling@xbill.org Created attachment 177580 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D177580&action= =3Dedit test case When a kqueue timer is created and updated (before the original timer fires= ), the update has no effect. See the attached sample program, which sets a oneshot timer for 1s in the future, then changes the period to 1ms, then wa= its. The final kevent call waits for (approximately) 1s, which would happen if = the update doesn't take effect. freebsd-11-x86-64-0:/u0/home/bwelling: ./timer kevent time: 1000124 On macOS Sierra, for comparison: wavelet:~: ./timer=20 kevent time: 1217 It's possible that reusing timers is not allowed, but I can't find anything= in the documentation that indicates that. --=20 You are receiving this mail because: You are the assignee for the bug.=
