Reported by paxed. A potion of oil, that was already in the midst of exploding,
got picked up through spot_effects(), which led to it merging with
another potion of oil and the freeing of the original obj.
The original obj pointer was still held by breakobj(), and breakobj()
proceeded to delete the obj (again).
Function nesting:
1 spelleffects()
2 -> weffects()
3 -> bhit()
4 -> bhitpile()
5 -> bhito(obj ...)
6 -> hero_breaks(obj ...)
7 -> breakobj(obj ...)
8 -> explode_oil(obj ...)
9 -> splatter_burning_oil()
10 -> explode()
11 -> zap_over_floor()
12 -> melt_ice()
13 -> spot_effects()
14 -> pickup()
15 -> pickup_object(obj ...)
16 -> pick_obj(obj ...)
17 -> addinv(obj ...)
18 -> addinv_core0(obj ...)
19 -> merged(obj ...)
20 -> obfree(obj ...)
21 -> dealloc_obj(obj ...)
8 -> delobj(obj ...)
9 -> delobj_core(obj ...)
10 -> obfree(obj ...)
11 -> dealloc_obj(obj ...)
12 -> impossible("obj already deleted)
This marks the exploding potion with LOST_EXPLODING, so that it won't
get picked up, or merged with another object during the long
sequence of functions, and that should take care of 15-21 above.
Previously, the code for monster healing was repeated every time it
was needed; this commit sends it all through a common function, which
will make it easier to make changes to how monster healing works in
the future.
This is just a code reorganisation and won't have any gameplay
effect unless I made a mistake.
The new EXTRA_SANITY_CHECK for a monster mimicking a monster. It
falsely triggered if the hero was hallucinating. Just add an
assertion that the monster index is within valid range.
The report (sent directly to devteam) stated that the bump-into-mimic
code might crash when bumping into a mimic that is masqueraing as
some other monster. Mimics don't actually do that, but the Wizard
of Yendor mimics another monster via Double Trouble. All I got from
it though is
|Wait! That's <other monster>!
which won't crash but is a fairly useless message.
This changes it to be
|Wait! That <other monster> is <the Wizard of Yendor>!
which seems a bit bland but provides useful information.
Use ESHK(shkp)->bill_p consistently. The bill[] array field is used
to initialize the bill_p pointer field rather than be used directly
when manipulating shop bills.
While in there, get rid of some '#if DUMB' from pre-standard C days.
I couldn't reproduce the reported problem but the backtrace suggests
that defsyms[monst->mappearance] was probably out of bounds so that
nh_snprintf() got bad data. That might conceivably happen if the
glyph didn't match the mimic's mappearance, but I not sure how that
would occur.
This avoids using mappearance as an index into defsyms[] and should
give an impossible if that situation does come up.
This time the no_charge object was being carried by a pet.
To trigger, drop an object into shop, decline to sell it,
pick up an object belonging to shopkeeper, decline to buy it,
wait for your pet to pick up the no_charge object you dropped,
teleport out of the shop, wait for shopkeeper to walk out of
the shop.
- Add a vision sanity checking routine
- Recalc block point when digging a door for temporary clouds
- Add recalc_block_point after cvt_sdoor_to_door, because doorways
on the Rogue level have no doors, and otherwise the sanity checking
would complain. This doesn't actually change how the Rogue level
vision works, as it uses a different vision system
- Monster using a trap in a secret corridor revealed the corridor,
but didn't unblock the vision unless you saw the location
Sanity checking was complaining about a no_charge obj in untended shop.
Angry shopkeeper was accepting thrown items as no_charge objects:
To reproduce the impossible, kick down the shop door angering
the shopkeeper. While the shopkeeper is still in their shop,
throw an item they don't want into the shop. Wait for the shopkeeper
to get out of the shop.
Move the anger checking before the sell auto-accept code,
so the shopkeeper will charge for the object.
remove_object cleared the vision when the last boulder was removed
from a location, without considering temporary [poison] clouds.
This particular case happened when pushing a boulder.
We can't just unconditionally unblock vision for a location when a boulder
falls into a pool, because the location may also have a (poison) cloud on it.
Apparently, restoring of saved games on Windows has been
broken since 1f36b98b, 'selectsaved' extension from Oct 10.
That change was altering the names of the files saved on disk
to a new format introduced at that time, but the game was not
opening a savefile with that same name, and the restore failed.
The code that renamed the savefile to match the internal name
was not part of 1f36b98b, it already existed prior to the new
internally-stored format.
To get things functional, this commit disables the code that
carries out the renaming of the on-disk savefile to match the
internal name in the savefile entirely, at least for now.
This relates to GitHub issue #1346 item 2.
Commit ba731a346b "fix shop steal when
teleporting your engulfer" mentioned that there was no longer any
message given if engulfer+hero got teleported. Add such. It is a
bit lame but the situation is rare enough that it should suffice.
Remove start_screen() and end_screen() from the
Window-port interface.
They were only ever used by tty, and there was a comment
carried to several window-ports about how they "really
should go away. They are tty-specific"
term_start_screen() and term_end_screen() are part of
terminal/NO_TERMS supporting routines now.
Add a note about NO_TERMS to include/wintty.h for clarity.
Rename tty_startup and tty_shutdown to term_startup() and
term_shutdown(). They are found in termcap.c for !NO_TERMS
like most of the other term_ routines, as well as having
versions for several of the NO_TERMS platforms. They aren't
part of the tty_interface called from the core. The tty
implementation does call and rely on them.
Remove some conditional #ifdef's around term_shutdown()
(formerly tty_shutdown()) and just ensure that all the
tty platforms have an implementation that they can link
with, even if it is just a stub presently.
Put the protype for nethack_exit in extern.h to reduce
maintenance to a single spot, and remove it from other
locations. A warning in the msdos cross-compile led to
this change.
Issue reported by ostrosablin: having Kick enabled as one of the
values for the 'autounlock' option succeeded it prompting "kick it?"
when walking into a locked closed door, but answering "yes" behaved
the same as answering "no".
There's bound to be a better way of fixing this, but this works.
Fixes#1360
Noticed when I summoned a quantum mechanic in wizard mode with a
starting character who should have no armor protection against their
teleport attack, but every touch resulted in "You are not affected". It
turns out the if statement checking for armor protection is backwards,
so you were never affected when you have no protection and were almost
always affected when you had good protection.
This appears to date back to when the all-purpose 'negated' variable was
removed and "You are not affected" moved to after the negation check;
the new conditional kept the ! by mistake.
Using #monster to make the steed use the breath weapon often
failed because the steed did not want to breathe at weak or
too strong monsters.
Make #monster force the steed use the breath, and if there is
no targets available, make the steed make some noise as feedback.
The tin-eating context was pointing to a non-existent object,
causing an error when the fuzzer somehow managed to continue eating
the freed tin object.
Clear the pointer when the tin leaves inventory or the object
is deleted.
Picking up a shop item and not paying it, getting swallowed
by a monster, and then teleporting the monster out of the shop
with you in it, the shopkeeper didn't notice the theft.
But the object was not marked as paid either.
Also prevent giving a message of the swallower disappearing
and appearing when it was teleported. (Although now there's
no message given, so something should be added ...)
If water walking boots haven't been discovered yet and underwater
hero rises to the surface when putting a pair on, discover them.
(Sinking while removing such on water already discovers them.)
Options processing can be early, even before ttyDisplay is allocated.
If we find that TTY_PERM_INVENT initialization is happening too early,
just set a marker (iflags.perm_invent_pending) to try again a bit later.
The changes in win/share are just to be able to sucessfully
reproduce the original issue on Windows. It was easily reproduced
on Unix, just by building with TTY_PERM_INVENT in include/config.h
and setting OPTIONS=perm_invent in config file.
This originated with a bug in NerfHack in which the developer specified
an inventory for a quest nemesis, but neglected to include the Bell of
Opening in it. Since monsters' inventory contents from makemon() were
tossed out completely, this caused a situation where the Bell was
deleted and the game was unwinnable. The first part of this change is
guarding against that by adding mdrop_special_objs before discarding the
inventory. This does create a possibility where if the programmer *does*
specify a nemesis get the Bell item in their inventory, while neglecting
to remove its special case generation in makemon.c, it would generate
twice - but two Bells is better than none.
Working on that fix led me to think about a limitation of the current
sp_lev.c behavior. You could either have a monster generate with its
species-typical inventory by not specifying an inventory for it, or you
could have it generate with custom inventory but then have to use that
to clumsily reproduce the normal inventory's complex chances and
conditionals in mongets(). So the remainder of this commit implements
another flag for des.monster(), keep_default_invent, that allows for
more flexibility in two ways:
1. When des.monster() contains an inventory function and
keep_default_invent is true, the monster will retain everything it
gets from makemon() and the objects in the inventory function are in
ADDITION to those. This is useful for augmenting a monster's default
kit with something to make them more threatening, or just more loot.
2. When des.monster contains no inventory function and
keep_default_invent is false, the monster will get NO inventory even
if its species is normally supposed to. I'm not sure where exactly
this would be used, but it doesn't hurt to have it available.
When keep_default_invent is not specified at all, the behavior remains
the same as it is now - if inventory is provided, default items are
discarded, and if not, they are kept.
My commit 82f0b1e8ea to make monsters which had nowhere
to move would panic attack the hero if possible, broke the
special unicorn handling; they avoid being in-line with hero,
so often had nowhere to move...
Fixes#1344
Remove the XP gain for tourist seeing a new type of monster
nearby, as it apparently made tourists a bit harder by forcing
early level gains.
Monsters next to hero are still marked as seen close-up, but
fix the code so it doesn't count undetected monsters.
Tourists still gain XP from "taking photos" of new types of monsters,
but only if they haven't seen the monster close up before.
(No actual photos are taken.)
Aka issue #1339 take II
For hero-owned container with some unpaid items, the itemized
shopping bill had a spurious index into the traditional shopping
bill (since it wasn't in that bill due not being unpaid). When mixed
with unpaid items that weren't in the container, that could cause
bill corruption while updating the traditional bill during payment,
leading to impossible warnings.
Fixes#1339Fixes#1350
Issue reported by ars3niy: with the relatively new container
handling, buying multiple items when some were inside a container
sometimes triggered impossible "unpaid_cost: object wasn't on any
bill" warnings and not buy all intended items. Once that occurred,
subsequent inventory display would repeat the warning.
A couple weeks back, I managed to produce a save file which would
reproduce the problem when 'p' was issued, but failed to figure
out why that was happening. I accidentally deleted that save file
and it took quite a lot of further attempts to get another one.
I still don't understand why this fix is needed, but with it in
place the save file no longer triggers any problems. I'm marking
the issue fixed but that could be premature.
Fixes#1339
