townlong-yak.com usually makes dumps of WoW code not publicly available, like a complete list of events or functions, in a special "Helix" folder included with their framexml UI code extract. They stopped about halfway through the 7.3 ptr cycle and then deleted what was dumped for 7.3 for some reason. The events list they had for 7.2.5 is still up and you can view it
here, along with what I saved of the last 7.3 dump before the stop and deletions
here (build 24651).
As for the events link Ammako provided, I would advise against using wowwiki for any code-related info, or nearly any game info for that matter. Many pages are sorely out-of-date and the wiki itself is not actively maintained.
Wowpedia is not only well maintained, it is considered the official wiki since it was linked to on Blizzard's item pages at some point. I'm not sure if the new site design still links to Wowpedia or Wowhead anymore, but the "blessing" should still be there.
