Prevent extremely long command line arguments from overflowing local
buffers in raw_printf or config_error_add. The increased buffer
sizes they recently got to deal with long configuration file values
aren't sufficient to handle command line induced overflows.
choose_windows(core): copy and truncate the window_type argument in
case it gets passed to config_error_add().
process_options(unix): report bad values with "%.60s" so that vsprintf
will implicitly truncate when formatted by raw_printf().
Fix 'Bugs 4, 5, and 6' which all use a similar fix but would have
conflicts over '#define BIGBUFSZ' if committed separately.
Format ("short explanation %s", string_argument), where the
explanation always has modest length but the string is potentially
up to 4*BUFSZ in length, into a 5*BUFSZ buffer. Then truncate the
result to at most BUFSZ-1 characters so that it can be safely passed
to interface-specific putstr() or raw_print().
Applies to pline(), raw_printf(), and config_error_add(). Also done
for impossible() although there's no evidence that its buffer could
be overflowed in a controlled manner.
Fix 'Bug 3' where too long SYMBOL=string in run-time config file could
overflow a local buffer and clobber the stack.
Valid value is only one character long after processing an 'escaped'
encoded character which can be at most 6 characters (plus terminator):
backslash M backslash and up three digits. If/when UTF8 gets added
the number of digits will increase. Use a truncated copy of the input
(substantially bigger than 6+1); ignore any excess.
Fix 'Bug 2' where too long MENUCOLOR=string in run-time config file
could overflow a local buffer and clobber the stack.
Theoretically a menu coloring regular expression could require a
bigger buffer but I don't think we need to try to support that.
255 characters minus the amount needed to specify color and/or
attributes should be ample.
have string_for_opt() return the value string or empty_optstr to
provide some level of crash protection if some future added option
processing misbehaves. Callers of string_for_opt() and
string_for_env_opt() should always check for a match to empty_optstr.
Poly'd hero hiding on the ceiling was told "you can't go down here"
if using '>' at a spot that didn't have down stairs, trap door, hole,
or pit. Let '>' bring a ceiling hider out of hiding; lurker above
resumes flying, piercer falls to floor or whatever is underneath it.
Fix some issues noticed when experimenting with ceiling hiders.
They're all blind (at least without the monks' Eyes) and some of
the behavior while blind seemed to be incorrect (though some that
I thought was wrong turned out to be ok; feel_newsym() won't update
the map if the hero can't reach the floor). Fixing that made me
notice that some terrain side-effects (being underwater or stuck in
lava) weren't getting disabled when the underlying terrain wasn't
the corresponding type anymore.
Allow a way to configure NetHack to run entirely from a USB stick
or other removable device in a way that allows everything to
reside entirely on the USB stick, and nothing on the computer's
hard drive. That could be done in versions prior to 3.6.3.
Sample:
i: is a USB stick
i:\nhdist contains the NetHack Windows distribution and a sysconf
file dropped into that distribution with the following entry in it:
portable_device_top = nethack
No device is included in the portable_device_top entry, the device
is always the device that the nethack exe resides on. If you try
to specify a device in the portable_device_top path, the device
portion will be ignored.
portable_device_top specifies the folder on the device that is writable
by NetHack and as such it cannot be the same folder that the executable
resides in.

Without that sysconf file in the NetHack distribution folder on the

return to the default locations for 3.6.3 on Windows:

Cherry-pick 3.7.0's 565e020573. Again,
conflict because the fixes entry goes into a different file.
When picking up from floor or removing from container fails because
there aren't any inventory slots available, pickup/take-out stops.
But the message
|Your knapsack can't accomodate any more items.
is inaccurate if there is gold beyond the stopping point. Actually
continuing in order to pickup/take-out gold would require substantial
changes, but varying the message to be
|Your knapsack can't accomodate any more items (except gold).
when stopping is a one line fix. The parenthesized remark is only
added if there is actually some gold after the current object and is
given regardless of whether autopickup happens to be targetting it.
Fixes#246
Cherry-pick 3.7.0's 4a3d5f95d9
(github pull request #252). Slightly tricky because the fix entry
nowgoes into a different file. fixes37.0 will need fixing up.
When you ride your steed into a polymorph trap and it changes into a
creature that can still wear the saddle, the message is
|You have to adjust youself in the saddle on <foo>.
which sounds as if the game is telling the player that he or she needs
to do something. Simplify it to
|You adjust yourself in the saddle on <foo>.
Submitted for 3.7.0; all but one also apply to 3.6.3.
I rewrote the curses terminal-too-small message instead of just
fixing the spelling of "minumum".
Changing from BETA to RELEASED resulted in turning off PANICTRACE
and that exposed a minor memory leak. Only applies to program exit
so doesn't impact play.
Taking off no-delay helmets, gloves, and boots were unintentionally
taking off suit instead and stayed worn themselves. As far as I
saw, only helmet types "fedora" and "dented pot" were applicable;
all gloves and boots have a small multi-turn delay. This was an
unintended side-effect of the first "slippery gloves" commit so
happened about three weeks ago.
Performance profiling showed that multiple strcmpi() calls were
occurring each and every time a character was going to the map.
This update:
- honors the WC_COLOR capability
- It allows a window-port to control individual color availability should the window-port wish to do so.
- Makes checking on the individual colors for the active window-port is a straightforward table lookup at the CLR_ offset.
iflags.use_color remains a master on/off switch for use of color, regardless of the capability
compiled into the game (default TRUE).
The has_color() routine, which is now a shared routine in src/windows.c, could likely be made
into a simple macro to eliminate the function call, but this update does not go that far.
This hits a lot of port files due to the window-port interface change, mostly cookie-cutter.

Add 'eating' (synonym 'continue') to the list of things that can be
set via paranoid_confirmation to require "yes" instead of "y" when
the user is prompted about something, in this case "Continue eating?".
dat/opthelp was missing a few of the paranoid_confirmation choices.
When a monster is drawn on the map, remove any "remembered, unseen
monster" glyph being shown at the same spot. Clairvoyance shows
all monsters in vicinty, then ones which can't be seen are replaced
with the 'I' glyph (which is on the object layer or the display,
not the monster layer show is subject to different update behavior).
But subsequent monster refresh didn't get rid of it when a sensed
monster was displayed over it. (3.6.1 included a similar fix for
warned-of monsters.)
Also during clairvoyance, don't draw an 'I' at a spot that will
immediately be refreshed with a monster because 'I' clobbers any
remembered object at the same location.
A reddit thread about an unaligned altar in an aligned temple was
a tipoff that mimics posing as altars didn't have any particular
alignment. The look-at code was misusing an operloaded field of the
underlying terrain. Pick an alignment at random when taking on the
appearance of an altar, store it in the mimic's mon->mextra->mcorpsenm
field, and have look-at use that.
Also, dropping a ring of polymorph into a sink can transform it, and
one possible outcome is an altar. In this case, the alignment is
part of the location's topology, but code setting that up was using
Align2amask(rn2(foo)). That's a macro which evaluates its argument
more than once. The first evaluation was effectively a no-op. If
the second evaluation picked lawful then the result was lawful as
intended. But if the second picked non-lawful and the third picked
lawful, the result would end up as none-of-the-above (a value of 3
when it needs to be a single-bit mask of 1, 2, or 4).
This is similar to the helm of opposite alignment case fixed some
time ago. Deferring the setting of foo->known until an item is fully
worn (because it used to get set earlier but gave away information if
the wear operation was interrupted) didn't take into account that foo
might end up Null in various circumstances. So Boots_on() needs to
validate uarmf before setting uarmf->known in case putting on boots
of levitation while on a sink caused them to come right back off.
I put similar validation into all foo_on() just in case (as far as
I'm aware, only Boots_on() and Helmet_on() actually need that).
I think the previous expression would allow moving (via swapping
places) from a pool to solid rock or closed door which was not what
was intended (but moot since there aren't any pools on the Astral
level). This revised expression does what is intended: can only
swap to a pool location if already located in/over (the Riders fly?
they should probably be non-breathing) another pool.
Don't let Riders swap places with something (fog or ooze, perhaps)
located at a closed door spot because if it gets killed there, there
won't be any corpse and it will stop auto-reviving.
Just avoid moving to spots where mondied() won't place a corpse
instead of worrying about whether a bargethrough creature (if there
ever are any besides the Riders) might be able to survive at the
destination (so ignore pass-walls, door-opening, swimming, &c).
Noticed while testing something: hero drank a potion of see invisible
and nearby invisible monster could now be seen--in theory--but I was
asked what to call the potion while the updated map was buffered. So
I didn't see the invisible monster until after naming the potion.
pline() flushes buffered map updates, but getlin() doesn't. I didn't
change that, but I've made docall() do so since the updated map may
make a difference in what the player can tell about whatever is being
'called'.
