Hello plaisthos, flichtenheld,
I'd like you to do a code review.
Please visit
http://gerrit.openvpn.net/c/openvpn/+/1113?usp=email
to review the following change.
Change subject: management: resync timer on bytecount interval change
......................................................................
management: resync timer on bytecount interval change
coarse_timer_wakeup tracks when the next timer-driven task will occur.
When a user issues `bytecount n` on the management interface but the
existing wakeup is more than n seconds ahead, bandwidth logging won’t
run until that original timer fires, delaying logs.
Introduce a flag to detect when the bytecount interval changes and,
when set, recalculate coarse_timer_wakeup so logging fires exactly
n seconds after the command. This guarantees bytecount adheres to the
user-specified interval.
