This construct triggered several complaints about passing Null to
Strcpy(simpleoname, obufp = the(simpleoname));
Changing that to
obufp = the(simpleoname);
Strcpy(simpleoname, obufp);
prevents it, but the original complaint is bogus and the "fix"
doesn't do anything to deal with Null arguments.
A couple of other changes introduce different code in order to get
different behavior. I updated from llvm-16 to llvm-19 but didn't
eliminate any of the spurious complaints.
Clear "next" boulder so that when pushing a pile of boulders, only
the first message for each of the 2nd, 3rd, &c will be formatted as
"next boulder". If any of them trigger additional messages, those
messages will use normal "boulder".
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.
makemon() has a 1% chance to bestow a worn saddle when creating any
rideable monster. If that chance kicked in on a knight's starting
pony, an extra saddle would end up being created but not worn nor
in inventory nor on floor so not be freed when the game ended.
That 1% chance also overrode saddle suppression for pauper knights.
There wouldn't be any extra saddle but their pony could start with
one, against intent.
Have makedog() (which is only used for starting pet) tell makemon()
to suppress inventory when creating the initial pet.
Overzealous change yesterday. For use_defensive(), the unicorn
horn case already has guards for Null item and the added one
issues bogus panic() when a unicorn or ki-rin uses its own horn.
I'm not really sure about this one. insert_branch(branch,) is
specified as not accepting a Null pointer and doesn't have any
defense against it, but the know level setup seems to allow a null
pointer through. I'm not sure whether this is the right fix.
If one or more boulders were next to lava and hero broke a wand of digging
next to that location, the boulder(s) stayed over the lava causing a sanity
checking error.
The missing break meant that executation fell through to the default
case and reset xlocale and ylocale to 0. The comment states that
this is for the fuzzer; I have no idea whether this fix matters to it.
Verifying that strlen(string) isn't too long, then allocating and
copying strlen(string)+1 draws a complaint about strcpy() overflowing
its output buffer.
Not an issue for regular play, but could matter for config file and
sysconf manipulation.
Picked arbitrarily; there weren't any unresolved analyzer complaints
for trap.c. I wonder why the onefile analysis isn't complaining here.
'in_sight' may have been relevant before the trapeffect_xyz() code
was split apart, but it isn't useful for trapeffect_hole() despite
the comment about it.
release_holding_trap() is fairly convoluted and the complaints being
addressed here were relevant.
This cleans up analyzer feedback in shk.c, based on the set of
warnings specified by hints/MacOS.370 and the lower level hints it
applies, rather than anything specified during periodic 'onefile'
processing.
shk.c is the only file I've analyzed, to try again to figure out
how to suppress the old complaint that has been causing a special
case in Genonefile. It isn't triggering during my testing but that
might be due to something in use by onefile but not by normal hints.
I'm running ccc-analyzer from llvm-16; I don't know whether that
matches Genonefile.
Casting charm monster with pets nearby could reset the edog struct.
If the pet ate a mimic corpse and was pretending to be something else
when that edog reset happened, the sanity checking would issue an impossible.
The error happened because meating was reset, but the pet appearance was not,
but the edog struct reset is the part being wrong. Lets not do that.
To reproduce, turn on sanity checking, create a tame dog, give it a mimic corpse
to eat, #wizcast charm monster next to it.
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.
