Build # 1450

Build Type

Pull #1290

travis-ci

Committed by

nosyjoe

Commit Message

modified method _schedule_next of PeriodicCallback to handle sudden changes of the system time differently:
 * calculating next timeout value directly while advancing by a multiple of callback_time
 * when the system time changes, jumps into the future make the _schedule_next method do a busy wait.
 * on slow machines (RPi), jumps of a few months into the future can block the loop for a few minutes
=> added a check for big differences in current system time and the current value of the next scheduled timeout

On a first boot of an older RPi image, tornado sometime starts before the date&time were updated through NTP, hence blocking the ioloop for several minutes.

Pull Request Pull Request #1290: Avoid busy waiting in ioloop when system time is skipped forward
