I was able to reproduce something similar in win32 by setting
the console to 21 rows. As he stated, don't let the game pick you
character for you to reproduce the problem. As soon as I chose
Archeologist the problem occurred:
Where:
In hack.c, weight_cap()
if (Levitation || Is_airlevel(&u.uz) /* <email deleted> */
#ifdef STEED
|| (u.usteed && strongmonst(u.usteed->data))
#endif
)
Variables:
carrcap 200
u.usteed 0x00000000
&u.uz 0x005e54aa
youmonst.data 0x00000000
Examination of the preprocessor output of that section
of code reveals that
"Levitation" becomes:
(u.uprops[47].intrinsic || u.uprops[47].extrinsic ||
((youmonst.data)->mlet == 5))
so it is the is_floater(youmonst.data) causing the crash.
Call stack:
weight_cap() line 2300 + 24 bytes
inv_weight() line 2342 + 5 bytes
calc_capacity(int 0) line 2354 + 5 bytes
near_capacity() line 2365 + 7 bytes
bot() line 607 + 5 bytes
docorner(int 47, int 19) line 2378
erase_menu_or_text(int 5, WinDesc * 0x00a22550, char 0) line 994 + 25 bytes
tty_dismiss_nhwindow(int 5) line 1664 + 15 bytes
tty_select_menu(int 5, int 1, mi * * 0x0006fc40) line 2248 + 9 bytes
tty_player_selection() line 442 + 16 bytes
pcmain(int 3, char * * 0x00a20eb0) line 457
main(int 3, char * * 0x00a20eb0) line 91 + 13 bytes
This adds a check for a valid youmonst.data in
bot().
From a bug report, attempting to attack
a hidden monster who is revealed by ongoing monster detection (blessed
potion or skilled spell) gave "wait! there's a <monster> hiding there"
response and prevented the attack. Make it behave the same as when the
hidden monster is revealed by telepathy; the monster comes out of hiding
and the hero's attack proceeds.
<Someone> reported that he applied an unID'd bag and it became
discovered as a bag of tricks even though a spellbook appeared on the floor
next to him rather than having a monster show up (the monster was a mimic).
Suppress the bag discovery unless you can see or sense a monster appear.
(This doesn't really achieve much for most players, who'll recognize the
bag because they know that only one type of container doesn't prompt to
take things out and/or put things in, but I think it does make sense.)
While mucking with bag of tricks I decided that to be consistent with
the behavior of other containers, the #tip command should release all the
monsters in the bag instead of just one.
And after doing that, I realized that horn of plenty ought to behave
much the same, so #tip will operate on it now. However, it won't be listed
as a likely candidate in the "which item?" prompt unless/until it has been
discovered. (Attempting to empty any other type of horn yields "nothing
happens", same as for a horn of plenty with no charges left.) Emptying a
horn of plenty in a shop can be extremely verbose, but I don't think that
qualifies as a bug and don't currently have any plans to alter it.
From a bug report: [ slashem-Bugs-1206099 ] Torches are not extinguished with rust traps).
A rust trap that hits the torso candles causes all lit objects being carried
to be extinguished, but one which hit the weapon arm didn't have same affect
on a wielded light. This fix causes wielded candles or lamps (not Sunsword)
to go out if affected by any rust, such as hitting a rust monster with one,
rather than use his patch that just handled the trap case. It also excludes
wielded lights from the existing torso splash since having them be hit by
both instances is too obviously buggy.
I think brass lanterns ought to be exempt from being extinguished by
water (at least splashing which is less drastic than total submersion) since
there are references to them operating by batteries rather than fire, but I
didn't want to track all the places which would be affected.

The user (<email deleted>) who recently suggested a
dump command for containers also wanted atmospheric sounds on levels which
have altars. Right now we'd have to find unattended altars the hard way
(by scanning the entire level) but we could add a counter (or set of
counters, one per alignment) like for fountains and sinks if we really
wanted to do that. [Now that I think about it, the #overview patch may
have already done something of the sort.] But what noises would an altar
be expected to produce? This only adds sounds for temples, where the
attending priest can be the source of the noise.
I'm not real thrilled with the initial set of sounds, particularly
the hallucinating one, but the implementation works. The "carcass" one is
a little clumsy; it's intended to add a hint for new players who haven't
figured out what the #offer command does.
Saving the game while punished, not carrying the attached ball,
and while swallowed by a purple worm resulted in losing the
ball and chain.
Since the required information was not being written to the
save file at all, I couldn't come up with a clean way to do this
for the branch, and preserve save file format. I could think
of lots of kludgy ways to do it (insert ball and chain into
the hero's inventory prior to saving, and remove it on restore, etc.)
When testing the spoteffects/drown hack I noticed that draining myself
with Stormbringer (toss up, get hit on head) while in iron golem form gave
messages about it drawing or draining life. (I'm sure that this has come
up before....) I've altered the artifact hit message rather than making
golems become resistant, although the opposite approach seems at least as
valid. The drain life spell uses different wording and isn't affected.
Attempt to fix a buglist item: if hero poly'd into iron golem form
enters a pool of water and drowning triggers reversion to human/whatever
form due to water damage, he will fall into that pool again, crawl or
teleport out, then redundantly crawl or teleport out for the initial entry.
[ spoteffects -> drown -> losehp -> rehumanize -> polyman -> spoteffects
-> drown ]
I don't have a lot of confidence in this fix. It does handle the
reported problem, and hasn't broken a couple of earlier tricky cases
(ice melting to water, land mine turning into a pit). But drown() and
lava_effects() seem to leave a trail of special case handling wherever
they appear so they--or spoteffects, or both--ought to be redone somehow.
I can't find the report about this; I must have deleted it after
reading, or else recently reread something so old that I'm not going back
far enough now. When you perform the invocation ritual to create the
stairs down to Moloch's Sanctum, any trap at your location gets deleted.
But if you were in a trapped state at the time then you got left in that
state. Descending stairs doesn't check for traps so you wouldn't notice
unless you tried to move around on the same level first. Then you'd get
"you're stuck in a pit/beartrap/web" even though it wasn't there anymore.
While testing the hiding vs traps patch, I became a mimic and hid.
It gets stuck to you.
Huh? Nothing was visible; nothing became visible (aside from the ']' at my
position changing back to 'm'). Display the invisible monster glyph when
an unseen monster bumps into you while you're hiding or mimicking gold.
That's usually handled by the hit and miss routines, but they aren't used
when you're just brought out of hiding instead of attacked.
From a bug report, the game gave feedback
about a monster becoming stuck in a web but there seemed to be no monster
around because it immediately began hiding under an object at the web's
location. Prevent monsters--or poly'd hero--from hiding when trapped in
anything other than a pit or spiked pit. Also, prevent them from hiding if
they're holding you or you're poly'd and holding them. I'm not sure whether
either of those cases ever actually happened but big mimics are capable of
both hiding and grabbing on.
Fix the problem From a bug report, where
giving a temple donation of the appropriate amount would fail to restore
protection previously stolen by gremlin attack iff the old protection amount
was big enough that the donation wouldn't have yielded a bonus in the normal
not-stolen case. It shouldn't be checking the magnitude of u.ublessed at a
time when lack of the intrinsic renders that value inoperative. After this
fix, the lost intrinsic will be granted and the old protection value will
be restored, same as happens when a prayer boon yields divine protection
(where no u.ublessed magnitude check is made) and as happened with donations
when the old protection was a more modest amount (magnitude test passed).
The bug report about losing/regaining the Protection intrinsic reminded
me of a couple of things. First, as an intrinsic, Protection seems to be
completely useless and we ought to redo it. Second, periodically people in
the newsgroup have complained about how it's nearly impossible to figure
out the important--possibly crucial--armor attribute of magic cancellation.
Wearing a cloak greatly increases characters' survival rates, but beyond
that, magic cancellation is just spoiler fodder.
This doesn't do much about Protection other than to change "you are
protected" into "you have a <small,moderate,&c> defense bonus" similar to
how the attributes conferred by rings of increase damage and increase
accuracy are handled. For magic cancellation, it adds new feedback:
You are protected. -- mc factor 3
You are guarded. -- mc factor 2
You are warded. -- mc factor 1
(with no extra feedback for mc factor 0, the normal naked state. The mc 3
case might cause some confusion over the changed meaning of a previously
existing item, but I think it'll be ok and not need re-wording.)
From a bug report, specifying role and race
along with invalid alignment for that role/race combination resulted in a
prompt of "pick the alignment of your chaotic human Valkyrie". This fixes
that particular problem, but the role selection code is incomprehensible
and I don't have a lot of confidence about whether other combinations have
similar trouble.
This also fixes an obvious typo in ok_align(). Unfortunately I can't
figure out what to do with the if-then-else block in root_plselection_prompt
which has identical code for its `then' and `else' halves (in the alignment
code that the new ok_align() test skips).
From a bug report, monsters with the wait
strategy (described as "meditating" by stethoscope probing) could be
affected by music but left meditating. Various wake up attempts shared
the same situation. Finish waiting if the monster would have been woken
(or pacified). I didn't search for places that diddle the msleeping bit
directly instead of calling one of the assorted wake() routines.
A fair bit of this is making usage of DEADMONSTER() be consistent.
Sooner or later there'll be another monster movement overhaul and those
if (DEADMONSTER(mon)) continue;
statements will all go away. (Probably just wishful thinking.)
When high priests have their affiliation suppressed to avoid giving
away which altar is which on the Astral level, the name formatting also
bypasses the code that converts "priest" into "priestess" for females.
(The bug report was about Moloch's high priestess; the occupant of the
Sanctum's temple gets similar handling to those on Astral.)
Also a tidbit for a change made a couple of days ago. Avoid using
"Manlobbi the invisible shopkeeper" or "Asidonhopo the newt" in the message
given when a shk refuses an attempt to be renamed via the 'C' command.
From a bug report, the 'C' command wasn't reporting that
"<shopkeeper> doesn't like being called names" even though the user's
supplied name was ineffective. Same thing for temple priests and other
minion monsters; the name was accepted but didn't do anything. Make such
monsters reject new names.
Fix a bug described in the slash'em bugs page at Sourceforge. When
attributes are undergoing adjustment (from drinking a potion of gain
ability, for instance), don't display "you feel wise" or "you feel weak"
messages if worn equipment is keeping the relevant attribute at some point
below max or above min and the current value doesn't actually change.
The old logic just checked whether you were at max or min and assumed that
when not, the value would be changing. Now it checks whether the value
actually did change. But it doesn't intercept attempts to go over max or
under min at the same point any more; I hope it hasn't introduced any new
bugs in the process.
Add a patch attached to one of the bug reports sent by <email deleted>
which prevents shopkeepers who have been polymorphed into animals from
speaking. Some messages are altered so that the player gets informed about
shop interactions without it seeming to be spoken by the shk, other messages
are suppressed outright. I cleaned it up a bit (mostly formatting, but the
``getcad'' section seemed to have a logic error--using goto to jump into
the middle of an if-then-else is evil...) and implemented a TODO comment he
added (to use mbodypart() when second shopkeeper at end of game shakes his
head; also, skip that phrase if shk is in headless form--futility while
attempting to test this led to discovery of the misplaced parenthesis bug).
Fix something I accidentally broke nearly three years ago (post 3.4.2,
so the bug appeared in 3.4.3). A misplaced closing parenthesis caused an
in-sight check to always fail, so the "<shk> looks at your corpse, shakes
his head, and sighs" message when game ends would never occur. That
situation is extremely rare anyway; it only happens after some other shk
has taken the hero's possessions.

Add the capability of sorting the entire spellbook by various criteria,
augmenting the existing ability to swap pairs of spells. In the menu that's
put up for the '+' command, add a non-spell entry after the last known spell
+ - [sort spells]
Selecting that brings up a new menu
View known spells list sorted
a + by casting letter
b - alphabetically
c - by level, low to high
d - by level, high to low
e - by skill group, alphabetized within each group
f - by skill group, low to high level within group
g - by skill group, high to low level within group
h - maintain current ordering
z - reassign casting letters to retain current order
'a' corresponds to the normal ordering; 'b' through 'g' cause the order
to change, but during the current invocation of the '+' command only.
(Entry 'h' is a no-op, something aside from ESC to get out without doing
anything. 'a' is only a no-op if you haven't picked any of 'b' through
'g' yet.) After making a choice, you're taken back to the '+' command to
view the spells in the requested order. And once back there, you can pick
'+' again to come back to this menu, where picking 'z' will cause casting
letters to be shuffled such that present display order becomes the actual
spellbook order. Newly learned spells get appended to the end as usual;
the most recent sorting order isn't sticky even if finished off with 'z'.
No doubt seeing it in action will be clearer than this description.
This also updates the Guidebook to mention the spell retention field added
to the '+' menu some weeks back.
Putting on the Eyes while blind causes sight to be regained, which in
turn causes xname() to set the dknown bit and start using the previously
unseen object's name. But obj_is_pname() was being called before xname in
the "you are now wearing ..." message, while dknown was still clear. So
obj_is_pname thought the name was being suppressed and returned false,
resulting in "an Eyes" instead of "the Eyes". Fix is to call xname first.
This patch by <email deleted> was released
when 3.4.1 was current and has been incorporated into slash'em. It is
extremely useful while using ranged weapons. When both autopickup and
pickup_thrown are enabled, walking across previously thrown objects will
pick them up even if they don't match the current pickup_types list.
[See cvs log for patchlevel.h for longer description.]
Fix the bug From a bug report.alt.org server, where killing a monster by closing the
castle drawbridge resulted in a panic after the dead monster's possessions
were dropped into the moat and a potion of acid exploded in the process.
water_damage() deleted the object but had no way to tell flooreffects()
that it was gone, so flooreffects() couldn't tell its own caller not to
place and stack the object. After that, a chunk of freed memory became
part of the floor objects chain and eventually triggered a panic which
tried to make a save file but whose reason didn't get logged properly.
From a bug report.c was first creating a corpse
complete with revive timer if it was a troll, or without
a timer if it was a lizard or lichen corpse. Then it might
change the corpse type, leaving strange corpse
types that revived, or that lasted forever.
We've been getting numerous complaints from people
about "dungeon failure", often related to attempts
to start NetHack from within various zip utilities
that present a folder-like view.
The dungeon failure was actually misleading. The
real problem was a dlb file open failure, but the
return value of dlb_init() was not being checked
in pcmain.
This moves the dlb_init earlier in the startup,
checks for failure, and provides some feedback
around the common zip utility problem for win32.
I've forgotten who pointed this out recently, but the hero was having
wisdom exercized (if true rumor chosen) or abused (for false one) whenever
level creation made a random floor engraving which used a rumor for its text.
From a bug report, a steed hit by disintegration
breath survived via life-saving, but the program was confused about whether
the hero could still ride and issued some impossible warnings. The code
to disintegrate a monster's inventory didn't bother to unwear worn items as
it destroyed them, presumeably assuming that the monster was sure to die,
so steed was left with a flag bit set claiming it was saddled even though
the saddle was gone. This fixes that, and the rider will end up being
dismounted as the saddle gets destroyed, regardless of whether the steed
ultimately survives. [Since the steed is still present at the time of
dismounting, the hero will get bumped to some other location, possibly to
the next spot about to be hit by the same black dragon breath attack which
just vaporized the steed. That's suboptimal, to put it mildly....]
I couldn't test the circumstances of the original report. Post-3.4.3,
ki-rin has been marked no-hands and is no longer capable of wearing armor
or amulets. I looked to see whether any other potential steed could wear
an amulet of life-saving and couldn't find one. But the original bug also
applied to conferred properties of special armor worn by non-steed monsters
too, so the fix was needed anyway.
The branch and trunk patches are different. For the trunk, I moved a
big chunk of code out of buzz() into a seperate routine. That actual fix
is the same in both variants.
Move part of the recent "munstone fixes" patch to the branch code
since one of those fixes prevents accessing freed memory. The part that
lets monsters eat tins of lizard meat or tins of acidic monsters in order
to get the same benefit as the corresponding corpse has been left out.
move oattached and oname and other things that vary
the size of the obj structure into a separate
non-adjacent oextra structure, similar to what has
already been done for mextra. The obj structure
itself becomes a fixed size.
New macros:
#define ONAME(o) ((o)->oextra->oname)
#define OMID(o) ((o)->oextra->omid)
#define OMONST(o) ((o)->oextra->omonst)
#define OLONG(o) ((o)->oextra->olong)
#define OMAILCMD(o) ((o)->oextra->omailcmd)
#define has_oname(o) ((o)->oextra && ONAME(o))
#define has_omid(o) ((o)->oextra && OMID(o))
#define has_omonst(o) ((o)->oextra && OMONST(o))
#define has_olong(o) ((o)->oextra && OLONG(o))
#define has_omailcmd(o) ((o)->oextra && OMAILCMD(o))
changed macros:
has_name(mon) becomes has_mname(mon) to correspond.
The CVS repository was tagged with
NETHACK_PRE_OEXTRA
before commiting these, and
tagged with
NETHACK_POST_OEXTRA
immediately after. The diff
between those two tags is this oextra patch.
The associated mail daemon changes to use an oextra
structure instead of a hidden command located in the
name after the terminating NUL, have not been tried
or tested.

hero already in a pit won't "fall into a chasm" from drum of earthquake
From a bug report, a monster who eats a lizard
corpse in order to cure confusion was treated the same as one who did so
to cure petrification, losing intrinsic speed in the process. In the same
report by <l>, monsters wouldn't eat lizard corpses to cure being stunned,
and those who ate them for another reason weren't cured of stunning, even
though the hero gets that benefit. While fixing those, I added some code
to let monsters who are carrying tins of lizard or acidic monster use them
if they're also carrying a tin opener, dagger, or knife. I don't think
any monsters except for nymphs are willing to pick up tins, so it won't
have much effect. It now works for nymphs though.
Examining the code while testing showed that mon_consume_unstone()
has been accessing the potion (acid) or corpse (lizard or acidic monster)
after the item had been used up, so that has been fixed too. I never saw
any detectable problems due to this, but folks using a debugging malloc
implementation which overwrites freed memory may have not been suffering
collateral acid damage or receiving intended confusion cure, or perhaps
did get either or both of those effects when they shouldn't have. Since
it only applied to monsters it wouldn't have been easy to observe.

<Someone> suggested that digging down on a land mine with a pick-axe ought
to set if off. I agree; this implements that and also for bear traps. In
the bear trap case, if you dig down once trapped, you will destroy that
trap explicitly rather than replace it with a pit, so it's now possible to
escape from one without leaving another trap in your wake. Once the bear
trap is gone, further digging there will make a pit as usual. While stuck
in one, digging down poses a modest risk of harming yourself.
|You now wield a pick-axe.
|You start digging downward. A bear trap closes on your foot!
|You start digging downward. You destroy the bear trap with your pick-axe.
|You continue digging downward. You dig a pit in the floor.
|You start digging downward. You dig a hole through the floor.
|You fall through...
[It seems a bit strange that finishing a pit discards all digging context,
so that resuming within the pit in order to make a hole "starts" digging
rather than "continues" it.]
Digging down with a wand or spell will disarm these two types of traps
and then leave the corresponding object (which may or may not fall through
the resulting hole, like any other object there). Digging to the side via
magic while trapped in a pit will also disarm such traps when it encounters
them. (When not in a pit, a digging beam which simply passes over an armed
bear trap or land mine won't have any effect on the trap.) Digging to the
side via tool behaves somewhat oddly ("no room for the rubble"?) and will
probably need some tweaking before eventual release; at present it doesn't
reach adjacent traps so didn't need any land mine or bear trap handling.
I put the fixes entry in the new features section.
<Someone> reported that thitu() was adding d20 damage for silver object
hitting silver-hating hero even though all the callers were using dmgval()
which also does that, resulting in doubled silver bonus/penalty. This
fixes that (including for boomerangs thrown by player, which weren't using
dmgval(), to handle a hyptothetical silver boomerang). While testing it,
I noticed that there was no "the silver sears your flesh" message when a
monster hit you with a wielded silver weapon, so this fixes that too.
(How did we miss that? And how did <Someone>? :-)
From a bug report, moving into a trap
during a failed untrap attempt didn't autopickup any objects there or
report about objects which aren't picked up. Although that appears to have
been intentional, change move_into_trap() to behave more like a regular
move. (I wrote this bit of code and don't remember whether the no pickup
aspect was deliberate; I suspect it might have been to avoid the redundant
"there is a trap here" message which you get when pickup checking is done
but not everything on the spot gets picked up. This patch suppresses that
message.)
I've been using this for a while; it is occasionally handy. #terrain
is a new wizard mode command which brings up a text display where the map
topology is revealed, similar to the obscure #wmode command but showing
different information. Also, #wmode has been tweaked a little so as to
actually overlay the tty-mode map exactly, rather than being off by one
line and one column. (That shouldn't really matter for other windowing
schemes where the map and a text rendition of it aren't very likely to
have a given location be displayed at the exact same screen position.)
The line of formatted flags info below the terrain display probably
belongs in a separate debugging command altogether where it wouldn't have
to be displayed in such a terse fashion.
Something I encountered while playing slash'em a while back, but
relevant to nethack: "Its orcish spears shatter from the force of your
blow!". I was using a two-handed weapon (at skilled or expert level) to
fight an invisible monster which was wielding a stack of multiple spears
(slash'em gives them out in groups of 3 for monsters' starting inventory).
After killing it, I found 2 orcish spears along with an invisible corpse
of somebody-or-other the Kobold King. The message suggested that the
whole spear stack had been destroyed (and the weapon shattering code in
hmon_hitmon() clearly expects that to be the case), but only one of them
had actually gotten used up.
I can't recall whether "shatter" was actually given as singular or
plural at the time; nethack handles that aspect correctly. Only object
destruction needed tweaking.
From a bug report, making engulf time longer for high AC
didn't make sense for non-digestion attacks: taking longer to die from
being digested (high AC lets you last longer there) is much different from
being stuck inside a vortex or elemental and suffering extra buffettings
or whatever. Calculate swallow time differently for non-digestion than
for digestion. (The adjustment based around level 25 doesn't make much
sense either, but I left that in.)
If you survive total digestion via life saving, you get a message
about the monster not liking your taste. I don't think that's appropriate,
but haven't tried to figure out how to fix it.
