Talk:Armor percentage rollover

This is entirely impossible. It would take 20GB of memory just to store the THINGS structures for the 2 billion things needed to cause a rollover, and there is no item respawn in 1.1. The dos extender that doom runs under could never possibly present to its program the existance of more than 4GB of memory space, as it uses 32 bit unsigned values as memory pointers. This is enough alone to conclusively prove that this bug would never trigger. An undesired behavior that can never ever happen is not a bug, just something that's been adequately guarded against. I could see the case for calling some of the size limits that come into play here bugs (like maybe the 2GB per lump wad size limit, which would be the first one you'd hit trying to reproduce this), but this simply cannot happen. 71.58.109.233 01:33, 20 September 2007 (UTC)


 * I was all ready to scream at you for erasing this, only it wasn't actually on this page. :>   As the person who started this article (the only other edit was to fix a typo which was present in the primary source IIRC), maybe I can respond anyway.  I think that


 * the second paragraph could indeed be chopped considerably if (as you and the other discussion argue persuasively) such an overflow is impossible rather than unlikely.
 * the article itself should remain, because although a mild anomaly, it has historical importance (it affected the design of WADs at the time and the fix was widely discussed) and arguably should have been noticed before the registered version was released.
 * the size limits that come into play here should all have articles.


 * The second and third points are based on the opening sentence in the Bugs article (written long before I arrived), which says that we are documenting "bugs, limitations and oddities", not just bugs. For example, Visible sprites limit is included even though (so I'm told) it was implemented intentionally to prevent massive rendering slowdowns.  People have questioned how broad this is, and rightly so, but so far no one has pushed for a formal, detailed notability guideline.  (Maybe Quasar would draft one, if he didn't have 2,147,483,647 other items on his to-do list already.)    Ryan W 05:16, 20 September 2007 (UTC)
