Pavel Tikhomirov dec084962e Do not treat C.sysconf(C._SC_NPROCESSORS_ONLN) non-zero errno as error ... Treat return code -1 as error instead. People from glibc say that errno is undefined in case of successful sysconf call according to POSIX standard: Glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=21536 More over in sysconf man it is wrongly said that "errno is not changed" on success. So I've created a bug to man-pages: https://bugzilla.kernel.org/show_bug.cgi?id=195955 Background: Glibc's sysconf(_SC_NPROCESSORS_ONLN) changes errno to ENOENT, if there is no /sys/devices/system/cpu/online file, while the call itself is successful. In Virtuozzo containers we prohibit most of sysfs files for security reasons. So we have Run():daemon /stats/collector.go infinitely loop never actualy collecting stats from publisher pairs. v2: add comment Signed-off-by: Pavel Tikhomirov <ptikhomirov@virtuozzo.com>		2017-06-01 18:23:49 +03:00
