4d55e1de79 Make saving grace also work against repeated damage sources
For example, being hit by the bounce of a wand of fire means that
the main character could take damage twice in a turn, which would
kill even through saving grace; and scrolls and potions could burn
up after that and finish off the last HP, even if the wand only hit
once. This commit changes it to track all damage done during the
turn, and prevent HP dropping below 1 from damage until the next
player action or the next turn boundary, whichever comes first.

966145a61d item action 'T' against covered armor
Using 'i'+menu choice for suit+'T' to try to take off a suit that is
covered by a cloak (or shirt covered by suit and/or cloak) wouldn't
do anything.  It should report that you need to take off the outer
garment first and then not take the chosen item off.

There is probably a simpler fix.  It took me a long time to figure
where things were going wrong and them cobble this together.

A big chunk of the diff for invent.c is just identation, surrounding
a one-line change there.

695c6ef3ac fix issue #1434 - engulfed gas spore explosion
Issue reported by Umbire:  a gas spore that got swallowed and killed
didn't die but exploded anyway, with the explosion affecting the map
instead of being contained in the swallower.

There was code to handle that but it wasn't being executed.  This fix
feels unclean but seems to work.

I couldn't reproduce the survival of the gas spore but since that
isn't wanted I won't worry about it.

f4a6da2e52 save/restore changes - part 2
This is the second of a series of changes related to save/restore.

    No EDITLEVEL bump has been included, because although the code
    is changed extensively by this, the content of the savefiles have
    not been changed.

    Push the use of the structlevel bwrite() and mread() function use
    out of the core and into sfstruct.c. This is groundwork for upcoming
    changes.

    In the core, replace the bwrite() and mread() calls with the
    use of type-specific savefile output (Sfo) and savefile
    input (Sfi) macros.  The macros are defined in a new header file
    savefile.h, which also contains the prototypes for the sfo_* and
    sfi_* functions that the macros ultimately expand to. The functions
    themselves are in src/sfbase.c.

    On C99, each Sfo or Sfi macro expansion refers directly to the
    corresponding  type-specific sfo_* or sfi_* function.

    If C23 or later is is use, the majority (all but 3 types) of the
    macros refer to a single _Generic output routine sfo(nhfp, dt, tag),
    and a single _Generic input routine sfi(nhfp, dt, tag), which handles
    the dispatch of the type-specific underlying functions. This was
    somewhat experimental, but turned out to be practical because the
    compiler would gripe if the type for a variable was not included in
    the _Generic when passed as an argument, so it could be fixed.

    This alters the savefile verication process by having a common set
    return values for the related functions such as uptodate(),
    check_version(), etc. The new return values return more information
    about savefile incompatibilities, beyond failure/sucess. The
    additional information will be useful for an upcoming addition.
    The expanded return values are:
     SF_UPTODATE                     (0) everything matched and looks good
     SF_OUTDATED                     (1) savefile is outdated
     SF_CRITICAL_BYTE_COUNT_MISMATCH (2) critical size count mismatch
     SF_DM_IL32LLP64_ON_ILP32LL64    (3) Windows x64 savefile on x86
     SF_DM_I32LP64_ON_ILP32LL64      (4) Unix 64 savefile on x86
     SF_DM_ILP32LL64_ON_I32LP64      (5) x86 savefile on Unix 64
     SF_DM_ILP32LL64_ON_IL32LLP64    (6) x86 savefile on Windows x64
     SF_DM_I32LP64_ON_IL32LLP64      (7) Unix 64 savefile on Windows x64
     SF_DM_IL32LLP64_ON_I32LP64      (8) Windows x64 savefile on Unix 64
     SF_DM_MISMATCH                  (9) some other mismatch
    The callers in the core have been adjusted to deal with the expanded
    return values.

    Other miscellaneous inclusions:

       - go.oracle_loc -> svo.oracle_loc.
       - add a bit (1UL << 30) to  called SFCTOOL_BIT as groundwork
         for changes to follow.

a3e12550ea savefile changes - part 1
This is the first of several savefile-related changes to
follow later. This one is groundwork for those later changes.

Remove internal compression schemes (RLECOMP and ZEROCOMP)
and discard the savefile_info struct that was primarily used to
convey which internal compression schemes had been in use.

Relocate some struct definitions into appropriate header files
for use by code to come in later changes.

Remove the two struct size-related fields from version_info and
from the nmakedefs_s. Instead, include a series of bytes near the
beginning of the savefile, representing the size of each
struct or base data type that impacts the historical savefile
content. Those are referred to as the "critical bytes".
(Related note: the "you" struct required two bytes, low and high,
due to its size).

Compare those critical bytes in a savefile against the NetHack
build that is reading the savefile. This allows mismatch detection
early in the savefile-reading process, and a clean exit, rather than
proceeding to read nonsensical values from the file. Include some
feedback on what the first mismatch was when encountering
one.

For arrays stored in the savefile, use loop-logic in the core
to write/read the array elements one at a time, rather than in
a single blob. This will be required for changes to follow later.
(impacts artiexist[], artidisco[], svd.dungeons[], svl.level_info[],
svl.level.locations[][], msrooms[] field of mapseen, svb.bases[],
svb.disco[] objects[], svm.mvitals[], svs.spl_book[], svd.doors[],
go.oracle_loc[], utrack[], wgrowtime[])

This also adds data model to the long version information.

This invalidates existing save and bones files due to the changes in
the information at the start of the file.

57f86662fd try harder to have --showpaths succeed
This helps avoid a potential chicken-and-egg scenario
with the system configuration file (sysconf).

If sysconf wasn't accessible at the expected location, it
caused an immediate exit, without relaying any helpful
information. That happened even when using:
    'nethack --showpaths'

That's particularly unhelpful, because the --showpaths
output might have been useful towards understanding where
NetHack was looking for such things.

That left you without an easy recourse to identify where
the game is looking for the sysconf file. That might be
especially troublesome if you didn't build the game
yourself.

0ce2439e82 github issue #1275: curses init vs pauper
Reported by ars3niy, the curses interface could behave strangely on
the first turn if the 'pauper' option/conduct was specified.

There isn't any definitive flag indicating whether or not the game
has started.  Since 'moves' has traditionally been initialized to 1
rather than to 0, there were several instances of
|  if (moves <= 1 && invent != NULL)
being used to determine the starting state on the assumption that
once hero has inventory, the game has begun.  Introduction of the
'pauper' option made the test for non-Null invent become unreliable.
For paupers, the program would behave as if the game hadn't started
yet until the player finally made a time-consuming move.

This changes compile-time initialization of 'moves' from 1 to 0,
then sets it to 1 when initial inventory would be bestowed (even
when 'pauper' inhibits that).  That's probably not the best place
for it, but testing for 'moves==0' now should produce an identical
effect as 'moves<=1 && invent!=NULL' used to accomplish.

It would have been much simpler just to give paupers 1 gold piece,
or perhaps one rock, in place of usual starting gear so that their
initial inventory wouldn't be empty, but the moves+invent way of
checking for start-of-play has always bothered me.

Should 'pauper' be preventing 'nethack -X' from giving its starting
wand of wishing?  Conducts and explore mode don't really overlap so
maybe it doesn't matter.

6c0ae092c6 distinguish global variables that get written to savefile
The g? structs had a mix of variables that were written to
the savefile, and those that were not.

For better clarity and to distinguish those that end up in
the savefile, relocate some g? variables that get written
directly to the savefile into different structs.

This updates EDITLEVEL, although technically it probably
didn't need to, since savefile contents are not changing.

    gb.bbubbles         -> svb.bbubbles

    gy.ymax             -> svy.ymax
    gy.ymin             -> svy.ymin

Related note:
There are some pointer variables that are heads of chains that were not
moved from 'g?' to 'sv?', because they are not actually written to the
savefile directly, but the objects/monst/trap/lightsource/timer in the
chains they point to are. That can be changed, if desired.
Examples: gi.invent, gm.migrating_objs, gb.billobjs, gm.migrating_mons,

10c85d68bb fix #K4172 - selling all into container
When using #loot to put items into a shop-owned container on a shop's
floor, you are asked "Sell it? [ynaq] (n)" for each item, but the 'a'
and 'q' choices only worked as y or n for the current item.  By the
next one, the preferred answer had been reset to default and ynaq was
asked again.

Set a flag in use_container() to have in_container() set the sell vs
don't sell state for the first item but not for any others.  Reset
the state at the end of use_container() instead of after each item in
in_container().

This bug was present in 3.6.x, also in 3.4.3, and probably earlier.

1a58ed8de9 Rework object deletion
Make object deletion work similarly to monster deletion:
it's marked for deletion (by setting the where-field to OBJ_DELETED
and moved to specific deleted-objects chain), but they're actually
freed at the beginning of turn.

This may need some more tweaking, especially in places that iterate
over object chains, but fuzzing did not find any obvious problems.

Fix a case of accessing freed memory: a monster breathed at hero,
destroying some items.  The code stored the next item in the chain
(a cloak), but a ring of levitation was destroyed, causing hero to
plop down into lava, destroying the cloak.  The item destruction
code then tried to access the destroyed cloak object.
Make the code check the object where-field - which will be different
if the object was marked for deletion.  Also removed an extra loop
going through the whole object chain looking for the items to
destroy.

15db874f71 CHANGE_COLOR palette option adjustments
It was too early to call the windowport change_color() routine
while processing the config file. The windowport was not yet
fully operational.

Now the palette option processing will just place the rgb
value into the appropriate ga.altpalette[CLR_MAX] entry.

init_sound_disp_gamewindows(void) [allmain.c] calls
change_palette() [coloratt.c] and it will call the windowport
change_color() function for each ga.altpalette[] entry that
has been set.

Notes:
The rgb values stored in ga.altpalette[] have the NH_ALTPALETTE bit set
so that the rgb value of 0 can be stored and be distinguishable from
a "not set" entry.

The NH_ALTPALETTE bit is cleared from the rgb value in change_palette()
prior to calling the windowport change_color() function.

The syntax for palette is colorname/r-g-b.
For example: palette:black/12-12-12

colorname must be one of the NH_BASIC_COLOR names or a suitable
alias for one of those 16 entries.

Some of the windowport CHANGE_COLOR functions had the wrong parameters,
perhaps due to bitrot. Those have been corrected to match the prototype.

Do the groundwork for allowing glyph color customizations to
work when any symset is loaded and not restrict it only to
the enhanced1 H_UTF8 symsets.

The customizations in effect are still affiliated with a particular
symset.

Also closes #1224, but the PR itself references a data structure
made obsolete by this commit. The curses comment from the PR was
added into the code.

The PR also made several suggestions, but only the first
one has been included in this commit (and no longer based on
the handler), that being:
"allow defining colors if other symbol handling modes are used
(possibly limited to the standard 16 colors)."

FredrIQ also wrote the following suggestions in PR#1224:

Something I was also contemplating, unrelated to implementation of this
support in curses, would be the ability for the following:

allow defining colors if other symbol handling modes are used (possibly limited to the standard 16 colors)
allow defining attributes (for example: glyph:G_pet_female_kitten:U+0066/red/underline)
allow specifying glyphs as wildcards for defining global color/attribute changes

Something I also want to see are keywords for "don't change the current defined data". If this
were to be added, you could for example do this:
OPTIONS=glyph:G_*_fox:U+0064/blue
OPTIONS=glyph:G_statue_*:basechar/gray/underline
for "make all foxes use a blue color, make all statues gray with underline" without needing
to specify the relevant character for every statue. This ("basechar", "basefg", etc)
should perhaps also be added for MENUCOLORS and statushilites, so that you can, for
example, underline all items being worn without needing to specify a bunch of
near-duplicate rules for combining BUC colors + underline worn items
as per #1064

9ba0cf2ff0 fix memory leaks for #quit while in tutorial
The new change to reset discoveries and monster-stats when exiting
the tutorial used dynamic data which wouldn't be freed if player
used #quit and declined to resume the regular game.

It turns out that such a leak was already present for start-of-game
inventory that gets stashed away during the tutorial.

In both cases, it could happen at most once per game so wasn't a big

78252de3bc fix memory leak in iter_mons_safe()
While hunting for a memory leak in object allocation--which I haven't
found yet--I discovered one in monster movement.  iter_mons_safe()
allocates an array of (monst *) pointers for the monsters on the
current level, loops over that array to call a function for each
one, then frees the array.  But if the game ends while that called
function is running, execution never returns to iter_mons_safe() so
it wasn't able to free the memory.

Since that can happen at most once per game, it wasn't a signifcant
leak.  This fixes it anyway.

There was a second issue:  make sure that iter_mons_safe() doesn't
call alloc(0) to make the temporary array for zero monsters when
there aren't any on the level.  That might not be able to happen for
monster movement but the routine is written to be more general than
just movement.  alloc(0) could confuse the MONITOR_HEAP code.  In
C89/C90 I think malloc(0) is allowed to return NULL (don't recall
for sure; maybe that was just known pre-standard behavior for some
implementations).  Null return would trigger a panic even without
MONITOR_HEAP.  Don't know about C99 and later.

dc8d9d6cd0 Accessibility: Add location info to messages
Adds a new boolean option, accessiblemsg.  If on, some game messages
are prefixed with direction or location information, for example:

   (west): The newt bites!
   (northwest): You find a hidden door.

I added the info to the most common messages, but several are
still missing it.

1cfa966871 pull request #1143 - menustyle:Full 'A' choice
Pull request from entrez:  in the class filtering menu for multi-drop
and for loot in-or-out of a container, make choosing 'A' without any
other filter choices (such as all, specific class(es), cursed, unpaid,
just-picked-up, &c) become a no-op.

I started with the pull request and then undid much of it.  It would
have been simpler to start from scratch.  If you don't have option
paranoid_confirmation:AutoAll set, when choosing 'A' for all-without-
prompting as the only selection, operate as the PR has made things
work:  effectively, 'A' by itself is ignored and the operation ends
with nothing happening.

However, if you do have paranoid_confirm:A set, then continue treating
'A' by itself as if 'A'+'a':  everything.  Since paranoid confirmation
is specified, that will be followed by a confirmation prompt.

This also adds a context-sensitive hint to the menu about how the 'A'
entry works, shown every time when 'cmdassist' is On or just once (per
session) when that is Off.

The documentation probably needs some updating.

Closes #1143

10f29a9760 allow readobjnam arg to be nonnull
Have it key on &do_random_str instead of NULL,
and modify makewish() in zap.c for the new protocol.

3cfd579d37 init NhRect, before passing to selection_getbounds
selection_getbounds() has a check and early return.
Initialization will ensure a known state if that early return
were ever taken.

This is an alternative approach to pr #1163.
