  33 <!--beginarticle-->
  34 <PRE>I am considering adding a rotate log function to services (and to the ircd
  35 but that is beyond the scope of this list) which will automatically rotate
  36 the log each day at Midnight but am looking for a low/no performance impact
  37 determination that Midnight has occured.
  38
  39 The daylight build used to have an isMidnight function called in the &quot;main
  40 loop&quot; but this rarely succeeded  I guess because if Services happened to be
  41 idle or very busy at this time, Midnight passed before the isMidnight
  42 function activated.
  43
  44 Eggdrop has a number of settings for automatic log rotation and after
  45 investigation it uses
  46
  47   add_hook(HOOK_SECONDLY, (Function) core_secondly);
  48
  49 with the per second function checking for Midnight among other things.
  50
  51 Having not used this system before I wonder as to what impact on performance
  52 this may have on services. If anyone knows much about using per second
  53 routines or what impact it might have on services it would be much
  54 appreciated.
