Unexpected behaviour of attached objects' keys

I had always thought, since I had read it in the wiki at http://www.lslwiki.net/lslwiki/wakka.php?wakka=key that the key of an attached object changes each time you tp. Someone questioned this the other day, and we have both tested it, and they don't seem to change, much to my surprise. Well, llOwnerSay((string)llGetKey()); returned the same result before and after teleporting between two sims, even after resetting the script.

Is this a recent change, does anyone know, and does it have any wider implications? Or did I test it the wrong way?

Attachment key changes on teleport went away a couple of years ago. All the LSL wikis have outdated info in them, and hardly anything in the way of official specs ever get released, so if what you see first hand doesn't match what you read, go with what you see (and expect it to change without notice).

And before you ask..... the key doesn't change when you attach/detach either.

However, it CAN change.. if you relog.

It's an old trick, when moving a networked, non-web-enabled server object, to right click it and attach it to some bodypart, Then teleport to your new location, and select "drop".

It's really convenient when you're wearing 30 server objects at once. Your avatar looks very funny, a shifting pile of boxes.

It kinda stops being funny when you crash during the teleport.

Not when you attach from in-world and then drop back in-world, but it DOES change if you detach it (to inventory) then reattach it from inventory again. Basically, a new key is generated at the same times an 'on_rez' event is generated, not when the 'attach' event is generated.

I realised that, which is one reason I was intrigued, since it seems to mean that inter-sim teleports don't work the way I thought they did. I had assumed, wrongly, that the different servers just kept a record of what you had attached and re-created it on arrival at your destination (thus partly explaining why my hair and shoes sometimes attached themselves to my backside on arrival, I suppose). But clearly I was mistaken, as so frequently I am.
