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.
Supersedes #850

Closes #850
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.
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 '|'.

Fix: prevent traps in shops in the Tourist quest
The Tourist locate and goal levels have 2 shops each, and also have
various traps randomly placed on the level. Unfortunately, this does not
account for placing them in the shops, so it was possible to wind up
with a magic trap or falling rock trap or whatever inside the shop,
which the shopkeeper would not clean up.
This commit makes selections that exclude the shop areas, and picks the
traps from those selections, keeping the shop floors trap-free as their
customers expect.
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."

Fix: antigravity trap doors
Trap doors saved their destinations as an absolute level, rather than a
relative one, so if you loaded bones from a special level their
destinations would reflect the dungeon layout from the bones player's
game. For example, die on the Oracle level, on dlvl5, with a trap door
that goes to dlvl6. Another player gets those bones on their Oracle
level, which is dlvl8... the trap door would still go to dlvl6. Pretty
amazing trap door -- something you might see in a funhouse!
Include relative rather than absolute destinations in save and bones
files, much like stairs do, to avoid this problem.
I bumped EDITLEVEL because although this won't break save files in an
obvious way, it will interpret the (absolute) destinations in existing
save and bones files as relative, leading to some crazy long falls. :)

Fix: starving herbivore pet vs polymorphing corpse
The special handling of polymorphing corpses included an "is acceptable
food if starving" rule which ignored the pet's other food preferences,
so a starving herbivorous pet would become willing to eat a

Along the same lines but latent: if there were a vegan polymorphing
corpse, a carnivorous pet would eat it not only if starving, but also if
maltreated and on the verge of becoming feral.
Instead of trying to fix this by reimplementing all the herbi vs carni
rules specifically for polymorphing corpses, just have a "don't eat
polymorphing corpses if neither starving nor almost untame" rule, and
fall back to the normal palatable corpses tests once it's been
determined that the pet is willing to eat even a polymorphing corpse.

This was tough to reproduce but I finally managed it. The issue
text mentions that it was fixed by copperwater in xNetHack with
commit 8c4af50f0aa3e72522f3eb98df039ff25c2a1ea0 to the repository

the code has been impinged upon by changes, so I ended up applying
the contents of that commit manually.
The commit changes how/when monsters put on new armor rather than
anything directly related to vampires. Circumstances similar to
the example above now yield:
|You kill SpaceMannSpiff!
|The seemingly dead SpaceMannSpiff suddenly transforms and rises as

on one turn, then on the next turn the revived vampire produces:
|SpaceMannSpiff puts on a dwarvish cloak.
My test case only had one item of interest; I assume that the second
item of armor gets worn on a subsequent turn rather than at the same
time as the first one.
Require a free hand when tipping a container into another container.
Presumeably you need to open the destination container and possibly
keep holding it open.
If you try to tip a carried container into an unknown bag of tricks,
apply the bag (once) instead of performing the tip. (To 'open' the
destination as above.) Possibly slightly confusing if bag is empty.
When tipping a container, always ask for the destination instead of
doing that only when carrying other containers. Confirming floor
as destination can be annoying but having to do that sometimes and
skipping that sometimes is aggravating because it is error prone.
And floor is preselected so can be chosen with space or return.
(I wanted to change the selector letter for floor from '-' to '.'
and then keep '-' as an unseen group accelerator, but the latter
doesn't work for PICK_ONE so I've left '-' as-is.)
Don't display "monsters appear" after tipping a bag of tricks.
Monster creation gives feedback these days. (Comparable to recent
"summon nasties" fix.)

When tipping a magic-bag exploder from a sack or box into a bag of
holding, the choice of whether to call useup() or useupf() was
backwards. But nothing bad happened which is fishy.
Reported by k2: tipping one container's contents directly into
another container allowed transferring a wand of cancellation (not
mentioned: or a bag of holding or a bag of tricks) into a bag of
holding without blowing it up.
That's now fixed. There are other issues that this doesn't touch:
I think it's odd that you can transfer stuff from one carried
container to another but not from a carried container to a floor
container nor from one floor container to another one at same spot.
I didn't test shop billing so an not sure what happens when #tip
blows up a bag of holding and there are some unpaid items involved.
Using #tip on horn of plenty treats it like a container, but doing
that when it's carried doesn't offer the chance to tip its contents
directly into a carried container.
Tipping a carried container does not require free hands or even
limbs (for playability) but tipping such into another container
should require at least one free hand.
Renaming got_from_config[] (something that was done in the past)
to set_in_config[] (something to do in the future) is sufficient to
remove any confusion about why it is being set from 'O'. Since that
is the name of an enum value, use opt_set_in_config[] instead.
The definition of enc_stat[] got changed by a pull request nearly a
year ago ('const char *enc_stat[]' -> 'const char *const enc_stat[]')
but the separate declarations for it weren't changed to match.
Make the same change for hu_stat[]. Not sure why the pull request
didn't include it since the old declaration and the usage are same.
Reported seven and a half years ago: if you are in a vault but not

Then if you pick up gold while the guard is still in the wall breach

that gold and follow me!" "Repeat" refers to the follow part but
sounds as if it refers to the drop-gold part which isn't actually
being repeated. Keep track of whether the guard has issued a drop
gold demand and use that to vary the wording of subsequent "I repeat"
message.

Move the guts of doset_simple() into a separate routine. Initially
that was just to avoid having to increase indentation when replacing
'goto' with 'do { ... } until ()'. It ends up making the flow of
control easier to see.
doset() and doset_simple() each had their own static flag indicating
whether 'fmtstr_doset' had been assigned a value. Redundant
assignment produced the same value so it wasn't an actual problem.
doset_simple() probably needs to add menu_tab_sep support for WinGUI.
Qt is able to get by without it, but that's because it forces use of
fixed-width font when any line in a menu or text window has 4 or more
consecutive spaces. I don't think WinGUI does that.
The menu for #herecmdmenu includes "look at map symbol" but if you
choose that it auto-picks the hero's location. Looking at your own
'@' isn't particularly useful so only include that menu option if
the symbol or tile being displayed isn't the normal one.
My /usr/include/curses.h has various A_attribute macros but A_ITALIC
isn't one of them. Compiling cursmisc.c failed because one of the
uses of that wasn't guarded by #ifdef A_ITALIC. Instead of adding the
ommitted #if, substitute A_UNDERLINE for A_ITALIC when that's missing.
The select attribute menu when adding a menu color or a status hilite
now shows an entry for italic that's underlined (as expected) but the
underline entry itself does not display any sort of attribute. I
didn't pursue that.
