I don't think this solves the recent light source reports,
but it changes a couple of things in an attempt to get more
information.
1. Having gy.youmonst.m_id field always be zero makes it tough
to distinguish it from uninitialized memory, or a random memory
value. This changes the m_id for the hero's gy.youmonst.m_id
to always hold the identifier 1, instead of 0.
2. write_ls was taking the stashed pointer in the light source,
and using it to immediately extract the m_id field and search
for that m_id. This changes the approach slightly, to actually
try and locate the stashed pointer itself in one of the monster
chains. Only if the monster pointer is located, do we dereference
it to obtain the m_id field.
3. For the interim, mark the saved ls with another set bit when
there has been a failure to locate the monst. At this time,
no code is acting on that bit, but it can be seen in a debug
session.
Hopefully, the next report will provide enough information to
understand the scenario a little better.
Using 'f', if hero is wielding a polearm, and a monster is in range,
don't switch away even if we do have ammo in quiver and a launcher
in the inventory.
Merge the recent change in the effect of blessed scroll of taming on
already tame monsters with the earlier change of any taming on already
tame monsters. Non-blessed has a chance of boosting monst->mtame by 1
when it is less than 10, more likely the lower the current value is.
For blessed, boost by 2 after that, so possibly by 3 if it is very low.
Make spell of charm monster when skilled or expert in enchantment
spells behave the same as blessed scroll of taming. [I'm not too sure
about this; it may make the spell too powerful.]
Experience equivalent to killing a monster is gained when starting a turn
adjacent to and being able to see the monster.
Breaks saves.

GNU make looks first for a file called GNUmakefile, ahead of
looking for Makefile and then makefile.
Renaming sys/windows/Makefile.mingw32 to sys/windows/GNUmakefile
allows:
o src/GNUmakefile (for use by GNU make) and src/Makefile (for use
Microsoft nmake) to both reside in the src folder during build.
o src/GNUmakefile will be used by GNU make, without having to
explicitly specify "-f GNUmakefile" on the GNU make command line.
o src/Makefile will be used by Microsoft nmake, without having to
explicitly specify "-f Makefile" on the Microsoft nmake command line.
For the gcc build, the movemement of sys/windows/GNUmakefile needs
to be copied to src/GNUmakefile as part of the build process (see
sys/windows/build-msys2.txt).
For the Microsoft Visual Studio command line build with nmake,
sys/windows/Makefile.nmake needs to be copied to src/Makefile as
part of the build process (see sys/windows/build-nmake.txt).
They are both copied to the src folder from their respective
repository source file names when the nhsetup.bat file is used.
When a mimic in door form is hit by a wand of locking or wand of
opening or corresponding spell, bring it out of concealment like
was recently done for being zapped while in chest form. And give
some feedback rather than just changing the mimic's form to 'm'.
Give more detailed feedback when bumping into a mimic while moving.
Because newsym() would be called only on the head position of the worm,
if hilite_pet was on, the segments and head of a long worm would have
mismatched highlighting in the immediate aftermath of taming or
untaming.
gcc has recognized various "magic comments" for white-listing
occurrences of implicit fallthrough in switch statements for
a long time:
The range and shape of "falls through" comments accepted are
contingent upon the level of the warning. (The default level is =3.)
-Wimplicit-fallthrough=0 disables the warning altogether.
-Wimplicit-fallthrough=1 treats any kind of comment as a "falls through" comment.
-Wimplicit-fallthrough=2 essentially accepts any comment that contains something
that matches (case insensitively) "falls?[ \t-]*thr(ough|u)" regular expression.
-Wimplicit-fallthrough=3 case sensitively matches a wide range of regular
expressions, listed in the GCC manual. E.g., all of these are accepted:
/* Falls through. */
/* fall-thru */
/* Else falls through. */
/* FALLTHRU */
/* ... falls through ... */
etc.
-Wimplicit-fallthrough=4 also, case sensitively matches a range of regular
expressions but is much more strict than level =3.
-Wimplicit-fallthrough=5 doesn't recognize any comments.
Plenty of other compilers did not recognize the gcc comment convention,
and up until now the compiler warning for detecting unintended
fallthrough had to be suppressed on other compilers. That's because the code
in NetHack has been relying on the gcc approach, and only the gcc approach.
The C23 standard introduces an attribute [[fallthrough]] for the
functionality, when implicit fallthrough warnings have been enabled.
Several popular compilers already support that, or a very similar attribute
style approach, today, even ahead of their C23 support:
C compiler whitelist approach
--------------------------- -------------------------------------
C23 conforming compilers [[fallthrough]]
clang versions supporting
standards prior to
C23 __attribute__((__fallthrough__))
Microsoft Visual Studio
since VS 2022 17.4.
The warning C5262 controls
whether the implict
fallthrough is detected and
warned about with
/std:clatest. [[fallthrough]]
This adds support to NetHack for the attribute approach by inserting a
macro FALLTHROUGH to the existing cases that require white-listing, so
other compilers can analyze things too.
The definition of the FALLTHROUGH macro is controlled in include/tradstdc.h.
The gcc comment approach has also been left in place at this time.
Issue reported by elunna: sleeping mimics can grab the hero, and
zapping a concealed mimic with a wand of sleep describes the target
as a mimic but doesn't bring it out of concealment.
The grab-when-asleep case is reasonable. It's a reflexive counter-
attack by a magical creature. And the mimic wakes up in the process.
But the mimic wasn't being brought out of concealment. Do that.
Unconceal mimics hit by wand of sleep unless already sleeping.
Fixes#1299
Issue reported by youkan700: shape change anomalies. Shapechangers
could change shape despite active protection-from-shape-changers if
hero wore two rings of protection from shape changers and took one
off. Shapechangers who migrated to a not-yet-visited level that
eventually got visited with protection from shape changers in effect
would be stuck in their current shape, even if the PfSC attribute
got toggled off and back on.
The issue included suggested fixes and those are what I've used. I
noticed a third case that only applies to wizard mode: if player
used #wizintrinsic to set a timed value for PfSC, monsters wouldn't
resume changing shape after it timed out, unless/until it got toggled
on and back off via a PfSC ring or hero left the level and returned.
Fixes#1312
If a vampire in fog cloud form moves under a closed door and then
before moving further gets killed and revives in vampire form,
destroy the door instead of moving the vampire to a nearby open
spot (which might be a distant spot if the map is crowded). If the
door is trapped, explode the trap. That will damage the vampire but
usually not by enough to kill it.
This probably ought to be generalized to be done for any shape change
at a closed location but I ran out of gas.
Change noit_mon_nam() to work as if it was noit_y_monnam() (without
renaming it or adding yet another monster naming routine) to use
"your <mon>" rather than "the <mon>" when <mon> is a pet that can
be seen (so not the case where "it" gets replaced by "someone" or
"something").
Commit c4a1f298e8 two and a half
months ago gave lawful Angels and Archons a chance to start with
a mace instead of a long sword so that they might get Demonbane.
It was a bit convulted; this redoes it to be more straightforward.
Fix a FIXME in Amulet_off() for removing an amulet of magical
breathing when within a poison gas cloud.
Redo message sequencing for both Amulet_on() and Amulet_off().
Use up an amulet of change if put on while the Unchanging attribute
is active (via #wizintrinsic) instead of wearing it with no effect.
Don't discover amulet of strangulation if put on while already
Strangled (via #wizintrinsic).
Add enlightenment feedback for Sunsword's blocking of becoming blind
from light flashes. It uses an extra property so that wizard mode
can report the reason.
EDITLEVEL is being incremented, so existing save and bones files are
invalidated.
When accessiblemsg is Off, coordiates supplied for various messages
stayed put after becoming stale. If you used 'mO' to toggle that
option On, you could see things like
(2east):'accessiblemsg' option toggled on.
After that, accessibility message coordinates behaved as intended.
Clear a11y.msg_loc.x,y for every pline instead of just when they
are used to augment the current message.
Most players who use accessiblemsg are bound to set it in their
config file rather than toggle it interactively so never noticed.
Misc 1: option.c doesn't need '#include <ctype.h>' because
cstd.h includes it unconditionally. Several other src/*.c are in
the same situation but I didn't touch them.
Misc 2: move set_msg_dir() and set_msg_xy() out of a warning
suppression block that isn't relevant to them.
If eating a tin killed the hero (choked, turned to stone, poly'd into
a new man with new Xp too low to survive) and bones were saved, the
tin remained intact in them.
When hero who is poly'd into metallivore form eats a tin, give a
little extra nutrition for the tin itself. Also, eat it immediately
by skipping the "It smells like <creature>" message and "Eat it? [yn]"
prompt. (The message while eating it also reports <creature>, so
skipping the 'smells' one doesn't end up hiding anything.)
In sys_early_init(), the values for sysopt.gdbpath and
sysopt.greppath were being assigned by calling dupstr()
without ensuring that a value previously assigned by
dupstr() were free()'d.
Also, the sysopt struct definition is changed to sysopt_s,
not because there's anything wrong with the original
struct sysopt sysopt;
but because I couldn't convince the debugger to use the
correct thing when trying to track down the leak.
