Suppress close to 400 warnings generated by gcc on the win/X11/*.c code,
most due to -Wwrite-strings which makes string literals implicitly have
the 'const' attribute. (Since modifying a string literal results in
undefined behavior, that is an appropriate check to have enabled, but
it can be troublesome since string literals have type 'char *' and code
that uses them that way is correct provided it avoids modifying them.)
113 warning: initialization discards qualifiers from pointer target type
127 warning: assignment discards qualifiers from pointer target type
29 warning: passing argument discards qualifiers from pointer target type
109 warning: unused parameter
12 warning: comparison between signed and unsigned
The nhStr() hack casts to 'char *', explicitly removing 'const', for
situations where it isn't feasible to make code directly honor const.
The vast marjority of uses are for the second parameter to XtSetArg(),
which is a macro that actually performs an assignment with the second
argument rather than passing it in a function. It takes values like
'XtNtop', which doesn't need to be altered (although in many places I
changed that to nhStr(XtNtop) for uniformity with the surrounding code,
and 'XtNbottom', which does need to have the extra const stripping to
avoid a warning. Go figure.
The nhUse() hack actually uses its argument in a meaningless way if the
code is compiled with FORCE_ARG_USAGE defined. When GCC_WARN is defined,
FORCE_ARG_USAGE will be enabled if it hasn't been already. Example:
/*ARGUSED*/
int foo(arg)
int arg; /* not used */
{
+ nhUse(arg);
return 0;
}
The extra line will expand to ';' when FORCE_ARG_USAGE is not defined
or too
nhUse_dummy += (unsigned)arg;
when it is. I figured direct assignment might lead to a different
warning by some compilers in a situation like
nhUse(arg);
nhUse(otherarg);
where the first assignment would be clobbered by the second, and using
bitwise operations or safer '+= (arg != 0)' would most likely generate
more non-useful code. Some tweaking might turn out to be necessary.
modified files: include/hack.h, src/decl.c, sys/unix/Makefile.src
Groundwork for cleaning up the X11 sources, where gcc with the option
settings specified in the OSX hints file currently generates close to
400 warnings for win/X11/*.c.
lint.h is included by hack.h, and I've moved the debugpline stuff from
the latter to the former to hide it better. (By rights it belongs in
debug.h or something of the sort, but I didn't want to go that far.)
Makefile and project dependencies need to catch up.
nhStr() hides a cast to char *, and is intended to by used on string
literals where it isn't feasible to maintain the 'const' attribute.
(A pernicious problem with X11 code, where the include situation can
become very convoluted, and many, MANY string literals are hidden
behind macros to look like keyword-type tokens.)
nhUse() can be used to force a fake usage on something which triggers
an unused parameter warning. There are a 6 or 8 or 10 places in the
core code where that applies, but so far I have't touched any of them.
There's a tradeoff since it will result in some worthless code being
generated and executed, but is much simpler than tacking on compiler-
specific workarounds like '#pragma unused' or gcc's __attribute__ hack.
Handle !fixinv by forcing gold to have slot '$' all the time; that
particular type of object is 'fixed' regardless of user preference.
Also add a couple of checks for non-'$' gold when selecting from
inventory, just in case the issue of multiple gold stacks reappears.
Lit candles and burning potions of oil can be on the migrating objects
list and get deleted before arrival, so they need the same cleanup as
rotting corpses to prevent obfree from complaining that they're worn.
Thinko fix: sanity checking for owornmask was mis-treating
OBJ_MIGRATING as OBJ_MINVENT of migrating monsters rather than as
unattended objects and would have had problems similar to obfree's
inappropriate impossible check.
Sanity checking for objects worn in invalid slots (amulet worn in
a ring slot and so forth) is extended to items worn by monsters.
Also add a check for wielded coins since the loophole that let them
become wielded has been closed.
Migrating objects overload obj->owornmask with a destination code,
so rot_corpse needs to clear that before deleting corpses. (Buried
objects don't touch owornmask, so rot_organic, which does the actual
object deletion, shouldn't need any similar change.)
The corpses with owornmask 3 that have been observed recently were
slated to arrive on the up stairs, so presumeably fell down the down
stairs of the current level and rotted before the hero went down.
Put plainly, it was the [post-3.4.3] impossible() check which was in
error, not the active game data.
'w$' reported "you can't wield gold" but
'w*$', choosing from inventory and picking gold, let you wield gold.
The old code checked whether gold had been picked before checking
whether '?' or '*' had been picked to request selection from inventory.
This wasn't an issue with 3.4.3's !GOLDINV configuration (but probably
was for anyone who explicitly switched to GOLDINV) because getobj()'s
callers only inserted gold into inventory when they intended to accept
it as a valid choice.
Fix is just to swap two adjacent 'if' blocks in getobj() so that '*'
is processed before the test of whether '$' has been chosen. Most of
the diff is indentation and other minor reformatting.
* Add missing entry for include/tile.h to (top)/Files; also
add new entry for generated file util/tiletxt.c (Unix only);
* Add several missing entries for tile utility programs that
can be built by sys/unix/Makefile.utl to util/.gitignore;
* Update sys/unix/Makefile.utl to build 'tilemap' differently so
that it won't leave behind an unwanted subdirectory tree under OSX:
util/tilemap.dSYM/
util/tilemap.dSYM/Contents/
util/tilemap.dSYM/Contents/Info.plist
util/tilemap.dSYM/Contents/Resources/
util/tilemap.dSYM/Contents/Resources/DWARF/
util/tilemap.dSYM/Contents/Resources/DWARF/tilemap
It now generates util/tiletxt.c on the fly, to be compiled into
tiletxt.o, so that tilemap.c can be compiled in the ordinary
manner and tilemap.o can be kept around for dependency checking.
(Creating real source file win/share/tiletxt.c would be a little
bit cleaner, but it's effectively two lines long so seems silly
to be in the source distribution.) I looked to see whether I
could find a linker or compiler option to suppress that stuff but
failed. I'm sure something of the sort must exist but didn't
pursue it. Someday I might actually learn about how OSX works....
wiz_identify (^I) is supposed to bring up the inventory list
with the items identified, in contrast to the regular (I)
inventory, but only for that inventory display.
It is intended that if you then hit ^I again while at that
wiz_identify inventory menu, you'll trigger permanent
identification of itemsand any other key is supposed to
leave them as they were.
In tty however, <space> was doing the same thing as the
second ^I, and permanently identifying everything.
So, for those that like to <space> through menus (like
me) this makes it work as originally intended and
requires a deliberate second ^I at the menu to permanently
identify. (It might also allow trigger permanent ID if you hit
underscore, but nobody "underscores" through menus,
so that's ok.)
