Actually, such a list of constants (yes, i mean constants) would actually be very useful.
currently I have to do a search for define(' over the entire vbulletin directory, and that just pulls up a ton of repeats and ones I know about already (like THIS_SCRIPT, TIMENOW, TABLE_PREFIX, etc).
Not to mention this doesnt cover the ones that can be defined, and get checked along the way, like DISABLE_HOOKS... a search for defined(' gets those, but again, this doesnt guarantee that it finds all of them.
And of course nowhere does it explain what each constant is meant to indicate or flag... magical stuff like SKIP_SESSIONCREATE or LOCATION_BYPASS... fun stuff which I can sort of guess what they do, but wish I could know for sure the exact implications to create optimized pages, ones that I know exactly what they need to do, and everything else will just be a waste of time and resources.
In fact theres one block I am trying to write which will simply echo out a row from datastore (an external system processes the output). except datastore can be stored in multiple ways which get handled by global, and I dont want the script to bother with sessions or any of the usual vb setup. just build the appropriate datastore system, get my row, and die

so, im trying to dig around to find the various constants to turn off everything else -_-
