[Crawl] Stash tracking bug?

While browsing through my *.lst file, I suddenly saw a yet unknown hat
in one of my stashes, a really good one btw (+2, with teleport),
something I surely would use now instead of my current +2 visored
helmet. So I rushed down to the Lair 8 and to my greatest disappointment
it was just the well known '+2 wizard's hat of Weirdness', nothing
special. The other 3 items where the same as shown in my *.lst file, so
I'm sure it was exactly this pile. After dropping the hat again, the lst
file now shows the correct content again.

I'm somewhat reluctant to mention that I also lost the information about
my stash of honeycombs and royal jellies. Reluctant cause though I'm
*sure* it exists, I'm not sure whether I left that stash in an secure
area or not. I'm pretty sure it was near the entrance of the Hive, I'm
going to have a look now...

As a less important sidenote (I guess this part wasn't touched), this is
still the "old" patch, w/o the multidrop enhancement...

This is the maddening randart-reshuffle bug. Tina Hall first reported
this, ages ago, but it's proved difficult to track down (part of the
reason it's been difficult to track down is that I haven't given it
much attention). I'll look into it again.

I'm anxious to see the result. 🙂

Well, I've neglected the stash-tracker for quite a while, so any bugs
in it are likely to have a long, dishonourable, history.

Well, that was a pretty stupid bug. It's not the first time I've
been bitten by sign-extension when casting a signed short to long.
Fixed now, thanks!

The fixed patch and Windows binary are up at the usual places:

http://www.angelfire.com/trek/mazewest/crawl/crawl-patches.diff.gz

and

http://www.angelfire.com/trek/mazewest/binaries/dc400b26tr-w32.zip

For your current game, you can make this change to your source and
recompile (or leave the code as it is - the bug should be harmless):

Replace the readLong() function at the end of files.cc with this
one:

long readLong(FILE *file) {
return ((long) (unsigned short) readShort(file)) << 16 |
(long) (unsigned short) readShort(file);
}

All clear, everything is in place. 🙂
Is it possible/thinkable that it also was an outcome of the
above-mentioned or another bug probably? Though I can't swear that I
just didn't forgot to mark that pile with ctrl-S, I consider this as an
unlikely case. This pile was (is) one of my more important ones.

My current char seems tougher than expected and, due to this really good
news, I just decided to change my mind, making a backup of my char and
trying the new patch...

At first the good news: I just compiled the patch, and - the first
multidrop test was successful!
<<<*XXL-grin*>>> (dunno how to express my joy)

But now the bad news. The bug above isn't solved. Here it is again:

(0, 0)
the +2 wizard's hat of Eternal Vigilance
It affects your accuracy (+4).
It makes you much more stealthy.
It lets you teleport.

Exactly the same hat as before, when I met the bug for the first time.
I wished it would be mine, but meanwhile I know it's not real... :-(

I've also found another curiosity, something entirely else, though.
When I compared my old crawl binary with the new one, I suddenly found
the new one significantly smaller. To be honest, I never took care of
the size of that binary, since it just worked. It's size is - fasten
your seat belts, please - ~17Mb! The new one is *only* ~7Mb in size, big
enough, but looks a lot more reasonable to me. Could anyone please tell
me how it's possible that 2 binaries of the same source differ so much
in size *and* are both working properly? I hardly can believe that the
patch could have something to do with it...

Great! 🙂

Could you revisit the square the hat is on, get out of LOS of that
square, save, reload, then dump and check the lst file? The hat
should be back to normal, and should stay normal thereafter. If not,
the bug is indeed alive and kicking.

What I see happening is this: when certain randarts are loaded from
the .st file, their properties get scrambled. Thereafter, the
properties stay scrambled until you actually go step on the square
in question (whereupon the stash-tracker throws away the items it
remembered and regenerates the list). The fix prevents the
scramble-on-load, but it doesn't affect already-scrambled items.

Whoa, both look huge to me. I don't know what the deal there is,
though.

I did it (for a small fee of 3 honeycombs you please send to the address
below ***). All clear, the *.lst file correctly shows the wizard's hat
of Weirdness now. 🙂

I'm clean out of honeycombs, but I can do beef jerky. Interested?

Neat!

No thanks. Now, where the usefulness of my amulet of controlled flight
has been somewhat relativated, I'm constantly wearing the amulet of the
gourmand again. And, as a result, I'm eating almost everything, most of
the time I'm full. This DE is going to be the fattest Elf you ever seen
before. If I continue this way, I'll soon get stuck in small one-square
corridors...

Never go hungry again, no matter what else might be wanting that slot! ;-)
