| 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 "main | |
| 40 | loop" 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. | |
