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.
Issue reported by elunna: when a room gets converted into a theme
room with fill type Garden, its walls are changed to trees but any
secret doors in those walls are still displayed as regular walls.
This adds a new D_ARBOREAL flag for secret doors, used to force them
to be displayed as a tree instead of a wall.
Fixes#1309
Grimtooth is now permanently poisoned, protects the wielder from
poison, and can be invoked to throw poison.
Permapoison code comes from xNetHack by copperwater <aosdict@gmail.com>.
Added the silver mace to be the base weapon type of Demonbane. It is appropriate that an artifact weapon designed to slay Demons would be made of (or plated with) silver. This helps to offset the damage reduction when Demonbane was changed from a longsword to a mace and makes it more specialized against silver-haters.
Set the probability to 2, equal to that of a silver spear.
Increased the weight of the silver mace by 120% -- equal to the weight increase from a normal spear to a silver spear. (Assuming the weapon is silver plated rather than made entirely out of silver.)
Increased the base cost to 60, a similar increase as spear to silver spear, to be an even number between silver spear and silver saber.
Monsters will prefer silver maces over regular maces.
Otherwise, identical in function to a normal mace.
There were couple reports of doors being generated in a corner
of a room. This happened for randomly generated irregular rooms,
because the code that was deciding if a corridor starting or
ending location was good did not handle irregular rooms at all.
This changes the corridor code so it can now generate start and
end points properly for any valid position in irregular rooms,
instead of only on the edges. This means the corridor sometimes
meanders a bit more than before, because it tries to find
the end point away from the edge of the room rectangle.
Also added is sanity checking for the randomly generated rooms
and corridors level, testing for door placement and room connectivity.
And another fix for a rare special case where dig_corridor
created a zero-tile long corridor; the entrance door was placed,
but there was nothing behind it.
Fixes github #1269 and #1385
Most recent version of XQuartz, same as before. Unfortunately,
newer version of macOS => newer version of Xcode and its command
line tools => newer version of clang => emulating newer version of
gcc which defaults to a more recent version of StdC, I suppose, or
perhaps our hints are specifying that. Whichever, it has resulted
in a bunch of complaints about XtOffset() used in win/X11/winX.c:
|warning: performing pointer subtraction with a null pointer has\
undefined behavior [-Wnull-pointer-subtraction]
Adding -wno-null-pointer-subtraction to X11FLAGS silences them,
but that would require figuring out which versions of gcc and
clang added -Wnull-pointer-subtraction and its negation. Revising
XtOffset() to include the ptrdiff_t casts eliminates the warnings,
avoiding the need for version conditionals to deal with X11FLAGS.
Instead of packing a coordinate into unsigned long, store the goal in
a coord struct, making the code a bit cleaner. Monster struct is
of course slightly bigger, but that should not really matter.
No change in monster behaviour.
Breaks saves and bones.
Some variants were already using a similar approach
using a struct called 'ebones', so adopt the same naming
so NetHack-3.7, hardfought, and some variants are using
the same name.
As before there are fields in the struct that are not
currently used by NetHack-3.7, but the intent is that
hardfought save and bones files can be loaded by
NetHack-3.7 without code modification, for debugging
bug reports.
This invalidates existing save and bones files.
Issue reported by elunna: the definition of the Mitre of Holiness
specifies that carrying it should confer fire resistance but that
didn't work.
The Mitre's definition (added in 3.1.0) has always included that,
but such a capability had never been implemented. Wearing it didn't
confer fire resistance either--its definition doesn't bother to
specify a 'defend' attribute since the 'carry' one should cover that.
This adds carrying capability for damage types fire, cold, sleep,
disintegration, electrity, poison, acid, and petrification. Fire is
still specified by the Mitre; none of the others are currently used.
Fixes#1362
There are two hardfought code additions that render save and bones files incompatible
with the upstream NetHack-3.7, and that makes testing with hardfought
save and bones files more challenging than it needs to be, when
investigating and troubleshooting bug reports.
Add some unused fields to advance towards achieving save file parity with
hardfought, which is a significant source of play-testing for NetHack-3.7.
1) the elbereth field addition to u_conduct
This adds an unused placeholder field named 'hf_reserved1', at the appropriate
place in u_conduct to achieve struct field parity with the one in use on
hardfought.
2) hardfought adds a field to struct monst:
char former_rank[25]; /* for bones' ghost rank in their former life */
Instead of adding that to every monst, this adds a new mextra struct
named 'former', which currently contains the equivalent 25-character
field called 'rank' which can hold the content that was in the
former_rank[25] field. That way, the field will only be added when it
is needed.
A pull request https://github.com/k21971/NetHack37/pull/2 has been
done on hardfought to do it the same way (untested there as of yet).
Even though NetHack-3.7 does not utilize that information presently,
this will be a further step toward allowing hardfought-generated save
and bones files to be used for troubleshooting, without modification,
on a similar architecture running stock NetHack-3.7 code.
That savefile parity won't be achieved until the after the
hardfought pull-request mentioned above (or equivalent) is merged.
As this change will not be compatible with existing save and bones
files, it will be accompanied with an EDITLEVEL increment.
Commit 1acc2727 helped ensure that the which_armor(mtmp, W_SADDLE)
test at the top of put_saddle_on_mon() wouldn't lead to an obj
leak.
This commit covers off the adjacent can_saddle() test in
put_saddle_on_mon(), because if that failed, it could also lead
to a memory leak of the saddle obj passed by the caller.
- have put_saddle_on_mon() create and use its own saddle obj
if a NULL saddle obj is passed, instead of having to do that
in the caller.
- where an existing saddle obj needs to be passed from the caller,
ensure that the caller has done its own can_saddle(mon) check prior
to calling put_saddle_on_mon(), so that the can_saddle() test
in put_saddle_on_mon() won't fail.
- lastly, add an impossible() to put_saddle_on_mon() to catch
a failure when a saddle obj is passed from the caller and either
test has failed, just in case. That should not happen with any of
the existing cases now, but it will provide some bullet-proofing
for new code, new callers.

Define a macro NH_C to provide a shorter & simpler way to test for
which C standard the build is being carried out under (c99 or c23).
NH_C > 202300L Being compiled under C23 or greater
NH_C > 199900L Being compiled under C99 or greater
NH_C > 198900L Being compiled under C89 or greater,
or C std could not be determined.
While NetHack only requires c99, we've been taking advantage
of some c23 features (attributes), if they are available,
to allow the use of ATTRNORETURN/NORETURN and FALLTHROUGH on
compilers other than gcc.
Also add some comment documentation to tradstdc.h about NetHack's
use of c99.
The sys/unix/Makefile.top change overcomes a warning in the
Makefile-generated nhlua.h. That warning arises under some compilers
that rely on attribute [[noreturn]] ahead of a declaration
(NetHack macro ATTRNORETURN), rather than the trailing gcc
__attribute((noreturn)) (NetHack macro NORETURN). The sed command
is modified to include ATTRNORETURN at the start of the declaration
in addition to the NORETURN at the end of the declaration, in the
generated file. That's the same combination that's used for the
declaration of other functions that don't return.
