Hi,
I have a single spread daemon and a bunch of programs communicating via
spread messages
through this daemon. All programs and the daemon are running on the same
machine.
>From previous mails on this list, I know that people have had problems
with message
delivery when they have changed the clock, via settimeofday and even NTP.
But I'm not sure if this can only occur when there are multiple daemons or
if it can happen
in my case too. Browsing through the code in events.c, it looks as it
could happen in my case
too, although the probability is perhaps small.
Has someone a testprogram/argument proving that this is either true or
false?
I'm thinking about changing the gettimeofday call in E_get_time to
something that is not
affected by some external source setting the time, for example,
clock_gettime(CLOCK_MONOTONIC).
Has someone done something similar before?
Cheers,
Drago
