I started activating new program_state.saving and discovered that
saving of ball and chain could access freed memory. The change
for the former and fix for the latter are mixed together here (but
easily distinguishable).
The saving flag inhibits status updating and perm_invent updating,
also map updating that goes through flush_screen(). That should
fix the exception triggered after an impossible warning was issued
during a save operation. impossible() goes through pline() which
tries to bring the screen up to date before issuing a message.
During save, data for that update can be in an inconsistent state.
The code to save ball and/or chain when not on floor or in invent
(I think swallowed is the only expected case) was examining the
memory pointed to by uball and uchain even if saving the level had
just freed floor objects and saving invent had just freed carried
objects. So for the usual cases, stale pointer values for uball
and uchain would be present and checking their obj->where field
was not reliable.
Move the core's global restoring flag (not the same as main()'s
local resuming flag) to a more logical place. Add a saving flag
in the process, but it isn't being set or cleared anywhere yet.
(Once in use it will probably fix the exception during save that
was just reported, but before that it would be useful to figure
out what specifically caused the event.)
The program_state struct really ought to be standalone rather
than part of struct g but I haven't made that change.
Removing an unused variable for wishing and some reformatting
that whent along with it got mixed in. Removes some trailing
whitespace in sfstruct.c too.
Only lightly tested...
This tries to fix the problem of the extra message when a tame
golem is completely destroyed (paper or straw golem burned, iron
golem rusted, wood or leather golem rotted) being issued at odd
times. I basically punted on the visibility aspect since the
original logic was strange: you had to be able to see both the
attacker's and defender's spots and at least one of those two
monsters. Now mon-attacks-mon visibility requires that you be
able to see one of the two and if you don't see both, the unseen
one will be referred to as "it". The "may the iron golem rust
in peace" message is independent of that and may be displayed
after "you have a sad feeling", but now that's intentional and
will refer to an unseen pet by name or monster type, not "it".
This needs a lot of testing and hasn't attempted to address
issue #402: only some attacks that should compeletely destroy
a golem actually do so. (So a hit by fire elemental against a
paper golem does, but passive fire counterattack when a paper
golem hits a fire elemental doesn't, nor does a wand of fire
or being hit by Firebrand.)
Fixes#401
"Name of your starting pet when it is a kitten" could be
construed as meaning that it will no longer apply once the
kitten grows into a housecat. Use "if" instead of "when".
The 'other settings' were in alphabetical order except for
"status condition fields" which presumably started out as
"condition fields". Move it into proper place for current
description.
Add a few missing options to dat/opthelp (without worrying about
"if FOO was set at compile time"). No doubt there are lots of
others still missing.
Reword a few options in dat/opthelp and also in the dynamic help
derived from optlist.h, particuarly catname, dogname, horsename
whose descriptions have always been confusing or maybe confused.
The revamped options handling was't doing dynamic help properly.
After listing the booleans, it listed them again amongest the
compound options. Since their description field is Null, that
could be a big problem. sprintf(buf,"%s",NULL) on OSX produces
"(null)" but most sprintf()'s would probably crash instead.
The 'other' options (autopickup exceptions, menucolors, &c) were
not listed at all. (I don't remember whether that was also the
case before the revamp.) Now they're listed but not explained.
The 'msg_window' description was unhelpful; this replaces it.
A couple of others were longer than necessary so they've been
shortened. The rest of optlist.h is reformatting wide lines.
Recently added 'safe_wait' option was included in the Guidebook
but not in dat/opthelp; add it.
Kicking a container that had gold in it took the gold amount
away from hero's credit or added to hero's debt, then didn't
give a refund if the container and its gold landed within the
shop. Throwing behaved likewise, just less verbosely.
The problem is caused by addtobill() treating gold specially
and then subfrombill() not being able to perform a reverse
operation. Actually, it may be possible for subfrombill() to
do that, but verifying all its uses is too much work. This
moves the gold handling for drop+selling into its own routine
and adds calls to that for the throwing and kicking refunds.
The other calls to subfrombill() outside of shk.c appear to be
ok as-is. (The calls inside that file are the ones that still
need evaluation if the gold handling is to move to there.)
bill_dummy_object() now uses the same o_id assignment for its
dummy object as split_object() does for its new partial stack.
I don't know whether the old code led to any price glitches.
Adds sanity checks for mtrapped and mundetected states.
Fixes cases where those were left in wrong state.
1. Trapped monster (eg. a nymph) teleported out of a trap
2. Monster was hiding under ball or chain, which then got removed
3. While restoring a level, a zombie corpse revived while monster
was hiding under it
4. A general case where the only object was deleted off floor and
a monster was hiding under it
Monsters hiding under ball or chain will now get revealed when
the b or c are moved.
When SCORE_ON_BOTL is enabled, you could tell how much gold is
inside a container with unknown contents by having 'showsore' On
and watching how much the score changed on the status line when
picking the container up.
From an old bug report (sent directly to devteam, June of 2017):
wand or scroll of create monster becomes discovered if it makes
a mimic that is concealed as an object or as furniture within
the hero's view. Fixing this in the general case [when does
seeing a mimic as something other than a monster mean that the
mimic is being seen?] is a massive can of worms, but fixing this
specific case is trivial.
Condense the Qt status slightly, moving Alignment field from the
Conditons line to the Characteristics line and the Time and Score
fields from their own possibly blank line to the HP,&c,Gold line.
That's for statuslines:2, which is the default. statuslines:3
restores the previous layout. I tried to make that become the
default for Qt but it got messy fast and I gave up.
I also tried to make changing 'statuslines' back and forth on the
fly work but failed. I left the code in as #if DYNAMIC_STATUSLINES
but that isn't defined anywhere. For the time being at least,
'statuslines' is config file or NETHACKOPTIONS only for Qt, not
changeable via 'O' like for curses and tty.
Change the option description for 'statuslines'. That depended
upon whether curses was compiled in when it should depend on which
interface is active. This moves the alternate info to Guidebook.
I was looking into adding a confirmation prompt for '!' and it
isn't very promising due to sequencing issues. (The check for
whether '!' is allowed should happen before the prompt about
running it but the latter should take place in the core rather
than in the port code.) In the mean time, I noticed that VMS was
ignoring the SHELLERS value from SYSCF.
Untested implementation of a SHELLERS check on VMS. Even if it
works, it should not be using $USER as the user name to verify.
Tweaks the Unix implementation of check_user_string() but doesn't
switch the testing loop to the simpler version used by VMS which
is derived from the generic users test used by Qt.
If we ever want huge maps with COLNO or ROWNO larger than signed char,
this will at least allow the game to compile and start when typedef'ing
xchar to int. Trying to use huge maps exposes more bugs.
