Reported by every for xNetHack. This bug is latent in vanilla, but can
easily start to present itself if themed rooms of a certain shape are
added. Ultimately, it comes from an assumption that shops will always be
rectangles of at least size 2x2, and the shopkeeper will always be able
to step diagonally backwards from their normal position just inside the
door in order to get out of the player's way.
Themed rooms introduce the possibility of shops where the shopkeeper has
only 1 square adjacent to their normal position to move to -
effectively, the shop entrance is a narrow corridor. When this happens,
they have nowhere to go to allow the player to enter or leave the shop,
leaving it permanently blocked unless the hero teleports or falls in or
out.
This fixes that by adjusting the shop algorithm to detect when a shop
candidate room is set up like this, and excludes it from becoming a
shop.
A monster which has grabbed you could move away without becoming unstuck
if it hit the "move and shoot" or "helpless" conditions in the dochug
MMOVE_MOVED case (since those lead to early return or break), leaving
the hero stuck to a monster which is no longer adjacent. Put the
'grabber moved away -> become unstuck' stuff at the top of the block so
that it will always be evaluated if a grabber has moved.
I would have liked to move the whole "grabber checks" block up, but I
think it'd change behavior to have the u.uswallow attack come before the
early return for a helpless monster, so I split it up instead.
Min Str is typically 3 no matter the hero's race, but could be higher
(at least in theory?). Using ATTRMIN makes losestr respect the same
minimum as other kinds of attribute loss (I'm operating under the
assumption that this wasn't an intentional move to fix the minimum at 3
regardless of other factors).
Since losestr and losehp calls go together most of the time, this feels
like it probably makes more sense than repeating the killer name/format
twice in a row all over the place.
Remove callers' responsibility to deal with possible hero death when
calling losestr. This is less fragile and error-prone than leaving it
in the caller's hands, but it means that death from the monster spell
'weaken target' no longer goes through done_in_by, and the death reason
is no longer "killed by <monster name>".
Killer format isn't a boolean, since it has 3 possible values
(KILLED_BY_AN, KILLED_BY, NO_KILLER_PREFIX). It shouldn't make any
difference behind the scenes, but it's confusing to use 'boolean' for
it.
...could leave hero in creature form with negative u.mh
losestr can subtract HP, but doesn't directly kill its target. The
caller is responsible for possibly killing the hero if losestr reduces
her HP to 0 or lower; most callers do this by combining losestr with a
losehp call, which can kill off the hero if necessary.
MGC_WEAKEN_YOU calls done_in_by if u.uhp < 1 after losestr, but didn't
handle the Upolyd u.mh case, so could leave a polymorphed hero with
negative health. Add a rehumanize call in that case.
This could also be done by changing losestr to call losehp itself for
the HP loss it deals out, but this would interfere with
cast_wizard_spell's use of done_in_by to generate the death reason:
either all strength loss is described one way ("terminal frailty" or
something -- not great) or else losestr must be passed a death reason
and is described a different way than other attack spells (because it
wouldn't go through done_in_by).
Monster purple worms can now gain intrinsics from swallowing foes whole,
so maybe the hero should be able to do so too. Intrinsics aren't
granted immediately upon swallowing (that would probably have been
easier), but only once a corpse is created and then entirely digested.
I'm not sure if this is too powerful and was being avoided deliberately
for that reason, since it includes potential level gain from wraith
corpses in addition to other intrinsics. That's consistent with monster
purple worms but may be a bit too much in the hands of the hero, though
it is limited by needing the corpse creation roll to succeed.
Issue reported by eakaye: for a 'hugs' attack to succeed, the
monster must have at least three attacks and the two preceding the
hug attack need to both hit. Guardian nagas had three attacks but
the first was melee 'bite' and the second was ranged 'spit'. Those
are mutually exclusive, so they would never both hit and nagas never
grabbed their prey.
Make the spit attack be first, the bite attack be second, insert a
touch attack for 0 damage third, and make the hug be fourth. Also,
change their hug damage type from 'phys' to 'wrap'. The first and
2nd+3rd+4th are still mutually exclusive.
The resulting message feedback left something to be desired and has
been tweaked.
The difficulty-level formula used by deprecated 'makedefs -m' now
generates 17 rather than 16 for guardian naga so I changed revised
monster to match. They are definitely more difficult now that their
constriction attack has a chance to hit.

Reported directly to devteam, mounted hero whose steed got hit
for knockback effect triggered impossible "no monster to remove".
In addition to fixing that, this makes a knockback attempt at a
hero who is stuck to a cursed saddle knock the hero and steed back
instead of knocking the hero out of the saddle.
mhurtle_step() should be able to use u.ux0,u.uy0 to update the
hero's old location after moving the hero in order to move the
steed, but the value was different from what was expected and the
map showed stale steed symbol when I used that. I'm not sure what
is going on there; saving u.ux,u.uy before moving the hero worked
as intended so I didn't pursue it.
Issue reported by eakaye: the alternate hobbit chat message is a
complaint about dungeon conditions, given if its current HP is 10
or more less than its maximum HP. But since hobbits are level 1,
they will almost never have 10 HP so won't be alive to chat when
at max minus 10.
Keep the old behavior if maximum happens to be more than 10, but
give alternate feedback when less than max if max is 10 or less.
Fixes#890
I was trying to reproduce the reported "no monster to remove" warning
from remove_monster() when a mounted hero was knocked off jabberwocky
steed but so far haven't been able to.
While trying, I came across a more minor bug. The hero got knocked
off a flying steed and got feedback of "you fly off" rather than
"you fall off". Flying capability came from the steed and dismount
feedback is aware of that but calls u_locomotion() which isn't. This
commit fixes that.
This adds some groundwork (DISMOUNT_KNOCKED) for better dismount
control. With a map fragment of
|....
|.Du.
|....
I got knocked off my steed by the attacking dragon and ended up with
|..@.
|.Du.
|....
It would be better to prefer spot 1, then the 2s, then 3s, then 4s
(not sure about farther spots if none of those are available)
|.432
|.D@1
|.432
when forced to dismount by knockback. This does _not_ implement that.
Pass the wait-for-response arg when displaying the wishing help text
window. tty, curses, and Qt waited regardless, but X11 honors the
no-wait request. It was showing the text window then letting the
core immediately resume, resulting in reissuing the wish prompt on
top of the help window. Entering a successful wish then dismissed
the prompt but left the help on the screen, possibly obscuring the
map depending on placement.
Reported by eakaye: orcish hero has maximum strength of 18/50 but
hero poly'd into an orc was given 18/100 strength. Also, a comment
from vultur-cadens pointed out that orcish heroes start with poison
resistance while monster orcs lack it.
Even though the boost to 18/100 is only temporary until the poly
times out, make orcs a special case where strongmonst from poly'ing
into them only gives 18/50 strength instead of 18/100. Adopt the
suggestion that Uruk-hai be an exception and continue to give hero
poly'd into them 18/100.
If any gnome becomes strongmonst (currently none are), treat them
as 18/50 too. Elvenking and elf-lord are strongmonst; treat their
forms as plain 18 though, matching the limit of elf heroes. Lesser
monster elves aren't strongmost.
While in there, add another special case so that hero poly'd into a
giant gets 19 strength. Monster giants are still plain strongmonst
so might warrant some sort of adjustment.
Give orcs poison resistance, but eating their corpses doesn't provide
an opportunity to confer it. Note goblins and hobgoblins still don't
have the resistance (to distinguish them from orcs a bit).
Take away strongmonst from orc shamans and give it to orc mummies.
Human mummies should have it too (at least according to movies) but
I didn't alter them becuase they're already pretty dangerous at the
point they start occurring. Take away strongmonst from plain 'elf'
placeholder.
New: when hero polymorphs into a form that lacks the strongmonst
attribute, take away any exceptional strength (drop 18/01 through
18/100 down to 18; as mentioned above, the drop is only temporary).
There's no attempt to set the maximum even lower for wimpy forms.

Suggested by entrez: when you search while engulfed the feedback asks

[sic] should be "engraving in frost mentions dust"
Writing on ice with fingers is described as writing in frost, but if
you overwrite an existing engraving rather than add to it the game
said you wiped out the engraving in the dust (immediately followed
by writing in the frost).
Not mentioned in the report: finishing a multi-turn engraving on
ice had the same problem.
Make the prompt for single genocide be more precise
from: What monster do you want to genocide?
_to_: What type of monster do you want to genocide?
and the re-prompt for it be slightly more verbose
from: What... [type the name of a monster]
_to_: What... [enter the name of a type of monster]
Also, make the already verbose re-prompt for class genocide even
more verbose
from: What class... [type the symbol representing a class]
_to_: What class... [type the symbol or name representing a class]
Possibly should have changed 'type' to 'enter' on the last one to
keep them consistent but I left that as-is.
The "[type the name]" prompt seems appropriate for handling via
cmdassist, so experienced players who don't need the help can hide it.
I also added a corresponding help note for the class genocide prompt.
So that a blank line wouldn't use up one of the player's "tries" for
class genocide, the game would continue to prompt until the input was
non-blank (or the user hit <esc>), with a tight loop around the getlin
call that only exited when it got some non-empty input. This apparently
risked leaving the game endlessly looping under some worst-case-scenario
hangup conditions. It was also inconsistent with normal genocide, which
doesn't have special handling of blank lines. Make the class genocide
prompt behave like the normal genocide prompt by removing the "blank
input" loop (and consequently treating a blank line the same way as any
other attempt to write a name).
The macro (currently unused, I think) for checking whether a particular
index designates a subroom was off by one on the maximum allowable
value.
Because of the dedicated extra space for the g.rooms array terminator
flag (hx == -1), subroom indices in g.rooms are set out in the range
[MAXNROFROOMS+1, MAXNROFROOMS*2], inclusive.
Also some minor formatting tweaks.
Make the token selling prices for unidentified gems not depend on how
many items were defined before FIRST_GEM. Now the unidentified gem
selling prices will depend only on the number and defined order of the
types of gems, and won't inexplicably change when objects are added,
or depend on compile-time options such as MAIL.
Also don't do the regular item price reduction for unidentified gems,
since they are already not based on the actual value. This restores
the pre-3.6 behavior, allowing players to gain a bit more information
from the nominal selling prices of unidentified gems.
Whoever first introduced this special handling for gems probably
intended for players to be able to gain information from gem prices
this way, but probably nobody has been doing it since 3.6.
Pull request #607 by Vivit-R proposed renaming "huge chunk of meat"
to "giant meatball" to better reflect the similarity to meatball.
But an object name that contains a monster name prefix requires extra
work in the wishing code. I considered "huge meatball" which retains
more of the original name but decided to go with "enormous meatball"
becaues it seems more evocative.

The menu to interactively set the windowborders option for curses
uses 'a'..'e' for choosing 0..4. Accept '0'..'4' (via unseen group
accellerator) too.
If environment had TTYINV=4 (perm_invent shows worn/wielded only),
disclosing inventory at end of game only showed worn and wielded
items instead of full inventory. Didn't matter whether perm_invent
is On or which interface is in use or whether game was built with
TTY_PERM_INVENT enabled.
This is an alternate way to deal with pull request #876, where
splitting a stack that has a name assigned updated perm_invent when
cloning the name and ran into trouble with shop billing when trying
to format for persistent inventory display.
The PR#876 fix has been left in place but wouldn't have been needed
if this had gone in first.
Reported by paxed 8 years ago: if a bones file contains a
doppelganger imitating a unique monster, when it gets loaded
that monster ends up being marked as having been created. The
doppelganger itself will shapechange to other forms, but the
unique monster won't be created when it should be because it has
become extinct.
Report involved creating a statue of a unique monster which
yields a doppelganger in that monster's shape, then using stone
to flesh to animate the statue, dying before it changes to some
other shape, and having bones be saved.
Pull request from copperwater: don't give "flash of light" feedback
when activating a level teleporter because it's too much like one of
the outcomes of a magic trap.
This doesn't use the suggested commit. Getting the "you feel
disoriented" feedback before being asked for destination level (when
having teleport control) seemed contradictory. This gives different
feedback and does so after the actual teleport.

Mark alloc()--also dupstr() and re_alloc()--for gcc and clang as
always returning non-Null. This should silence some of the static
analysis complaints.
Almost all the monster and object naming functions (anything that
returns an mbuf or an obuf) should be marked this way too but I'll
leave that for somebody else to deal with.
I didn't attempt to mark alloc() with the 'malloc' attribute because
macro definitions could end up causing trouble. Specifying its
deallocator would probably be useful but is at even bigger risk of
macro interference.
I'm not sure whether gcc 3 is really the right test for whether the
returns_nonnull attribute setting is available.
Year old issue from copperwater: 'open' directed at a non-door told
player that there isn't a door and took no time unless character was
blind and learned what type of terrain it is, applying a key gave
the same message but used a turn and didn't update map to reflect any
terrain discovery.
Attempting to open an adjacent door or applying a key to one while in
a pit had a similar issue: they produced the same "you can't reach
it from here" but had different time vs no-time outcome.
There may be other actions in the same situation.
Closes#581
Noticed that an attempted terrain replacement wasn't taking hold even
though 'w' is supposed to mean "match any stone or wall"; this was
because w converts into non-terrain-type MATCH_WALL and replace_terrain
was doing a simple comparison on whether the potentially replaced
terrain matches that type. Add a special check here for w so it will
match the terrain types it's supposed to.
Note that using replace_terrain with 'w' now WILL match stone, since
this is the documented behavior of w, to match IS_STWALL rather than
just IS_WALL. If a level designer really wants to exclude stone, they
can work around this by either making a selection and filter out stone
terrain, or doing two replace_terrains with '-' and '|'.
Use the level passed in instead of the hero's location when checking
the dungeon branch.
It probably doesn't make any difference, but use the argument that's
already being provided.
Add a comment to the effect that engraving with Fire Brand doesn't
cause it to become dull.
[I'm not sure that is the behavior we really want. It seems like an
unintended side-effect of changing Fire Brand's engrave type to BURN.]
Someone asked whether the 'magr' argument to artifact_hit() can be
Null or not since the code sometimes checks whether it is Null and
other times uses it unconditonally. The answer is "it depends."

The way hole destinations work now theoretically allows for a
cross-branch hole or trap door to move you across branches in a way that
decreases your overall depth. If this happened, it would cause an
impossible when the negative result of (depth(new) - depth(old)) was
used to calculate fall damage. Limit fall damage to 1d6 if dist <= 0.
Missed this way to use the trap door (in a block added in 05761ba) in
previous commits, though I'm a little confused about whether that block
in dodown is even reachable given how various trap scenarios are handled
with dotrap earlier in the function.
