Last night I wrote the hairy calendar code to calculate when +next to run a scheduled event. (This is actually quite superior to `cron`, +which checks every second to see if it should run each event!) Today I +built a "Cronner" thread that handles spawning threads to handle each +scheduled event. It even notices when changes have been made to the its +schedule and stops/starts event threads appropriately. + +Everything is hooked up, building, and there's a good chance it works +without too many bugs, but while I've tested all the pure code (mostly +automatically with quickcheck properties), I have not run the Cronner +thread at all. And there is some tricky stuff in there, like noticing +that the machine was asleep past when it expected to wake up, and deciding +if it should still run a scheduled event, or should wait until next time. +So tomorrow we'll see.. + +Today's work was sponsored by Ethan Aubin. |
