Bug#502435: perl: Time::HiRes alarm is broken for etchnhalf kernels

See http://rt.cpan.org/Public/Bug/Display.html?id=34655 for some details. I agree it is 448965 and the diff from there should probably be considered for as a bugfix for stable. I'll take this up with the stable release team. The fix is as simple as adding -Ud_ualarm to debian/config.debian. This activates the ualarm() emulation code in ext/Time/HiRes.xs that uses setitimer() with valid timeval values. -- Niko Tyni [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

This sounds #448965 revisited, is the kernel returning EINVAL here? Just read 448965. It actually worked with 2.6.18. 2.6.18 complained: media-server kernel: setitimer: processor .pl (pid = 2675) provided invalid timeval it_value: tv_sec = 0 tv_usec = 500 However, it still worked despite the complaint. I agree it is 448965 and the diff from there should probably be considered for as a bugfix for stable. -- Understanding is a three-edged sword: your side, their side, and the truth. --Kosh Naranek A.

Indeed it does:
media-server:~# strace -e setitimer perl -MTime::HiRes=alarm -e 'alarm
2; sleep 4'
setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={0, 200}},
0xbfd3fff8) = -1 EINVAL (Invalid argument)
