Fix the situation where disabling PANICTRACE, which happened implicitly
when BETA got disabled, caused SYSCF option processing to complain and
quit if the 'sysconf' file contained any PANICTRACE settings.
Now accept all the PANICTRACE options (assuming SYSCF is defined) even
if PANICTRACE is not defined. Their values are recorded in the 'sysopt'
struct, but only validated when the appropriate macros (PANICTRACE,
PANICTRACE_LIB) are defined.
Change
|Bad option line: "foo
|"
to
|Bad option line: "foo"
by stripping away the input line's newline before processing it.
(This doesn't address the PANICTRACE options processing issue.)
With DEBUG suppressed, I started getting
16 warning: empty body in an if-statement
and 2 warning: empty body in an else-statement
from gcc.
Using braces for an empty block instead of just ';' avoids the warning:
if (foo)
debugpline("foo");
is bad,
if (bar) {
debugpline("bar");
}
is good. ;-)
The changes to lint.h are just precautionary.
modified:
include/lint.h
src/attrib.c, bones.c, dbridge.c, dig.c, eat.c,
makemon.c, mkmaze.c, mon.c, sp_lev.c
Shorten a function name in sp_lev.c that exceeded 31 characters.
That's a limit imposed by the VMS linker and the compiler complains
that it will be truncated.
Make all sp_lev.c functions which aren't listed in extern.h be static
and give all of them a declaration at the top of the file. I reordered
the ones already declared there in the same order as they occur in the
source, so the diff is quite a bit bigger than the actual changes.
(Once the one with the long name became static, the length of its name
no longer mattered, but I've shortened it anyway.)
Indent a couple of #pragma directives. Some pre-ANSI compiler didn't
like '#' in column 1 followed by something it didn't understand, even
when that occurred in a conditional block which was in the midst of
being excluded. (util/*_comp.y recently reminded me of that. files.c
should get a fix like this too.)
Reported by a beta tester months ago: it was possible to recognize
your god's temple on the Astral Plane by stepping into its doorway,
since #overview would show "temple of <your god>" (only if just one
temple had been entered and the altar in it was the only one you'd
seen and it was for your own god; #overview doesn't show "temple of
<other god>", just "a temple"). After this fix it will just show
"a temple" even when you can see the temple's altar, so #overview
can't be used as a shortcut to finding the right temple.
While testing the fix I discovered that amnesia wasn't handled when
forgetting the current level's map, only when other levels got
flagged as forgotten. The number of altars, fountains, and so on
are recalculated when #overview is executed, so current-level amnesia
worked for those. But data about known rooms is not recalculated,
so the number of temples and shops you'd visited on the level stayed
instead of being forgotten. The fix is a bit iffy for the case where
you only forget random spots scattered across the level's map rather
than the whole thing; this just wipes #overview memory of every room
even if parts of rooms are still remembered.
How that there's nothing left to trigger it, put in some extra quest
messge debugging code. Could be useful if new roles are added or if
any deliver-by-pline messages get changed to be deliver-by-window.
Another bit prompted by vibrating square testing:
|You see a strange vibration beneath the little dog's rear claws.
Fix up some body parts: dog, cat, and yeti-class (includes sasquatch,
monkey and ape, owlbear) already have "paws" instead of "fore claws".
Take away all 'Y' except owlbear from that list and add rodents to it.
Give them "rear paws" instead of "rear claws" for their feet; for legs,
use "foreleg" instead of "forelimb" and "read leg" instead of "rear limb".
For yeti/sasquatch/monkey/ape/carnivorous-ape, switch from paws to hands
since they have opposable thumbs, and switch to arm, leg, foot instead
of forelimb, rear limb, and rear claw. I've left "fore claw" for finger.
Noticed while testing the look-at vs vibrating square patch: I was
able to cover stairs with a trap via wizard mode wish. That wish can
achieve a lot of irregular things, but prevent this particular one.
When examining a trap with '/' or ';', show
|a trap (arrow trap)
instead of
|a trap or a vibrating square (arrow trap)
outside of Gehennom (unless the trap actually is a vibrating square,
which could happen via wizard mode wish). The extra verbosity is
distracting, and limiting mention of the vibrating square to the region
where it's relevant may give a hint to players getting that far for the
first time.
Preformat SYSCF entry 'WIZARDS' so that it can be displayed during panic
feedback without allocating memory for the formatted list at that time.
It also gets displayed for help's "support information" ('?k').
For panic(), push "it may be possible to rebuild" to a second line since
the formatted usernames might make the line long.
Mark panic() as never returning so that code analysis might be able
to do a smarter job. It required splitting done() into two routines
since the first part really can return (but not if PANICKED was the
reason it got called). done() is now much shorter and ends with a
call to new really_done(), and panic() skips done()'s might-return
part by calling really_done() directly.
Noticed in passing: the "report error to <list of SYSCF WIZARDS>"
code calls a routine which uses alloc(), which won't work very well
if the reason for panic was because malloc() ran out of memory.
On OSX 10.5, save file compression and uncompression fail when I run
under debugger control (for gdb, at least; I don't know why). I used
'#panic' to try something out. panic() calls exit_nhwindows(), then
after some messages calls dosave0(). Saving calls docompress_file()
and when that fails on tty it tries to call clear_nhwindow(WIN_MESSAGE)
but WIN_MESSAGE has been torn down already, leading to a nested panic().
Avoid the call to clear_nhwindow() if windows aren't up.
In the midst of composing a commit message about how I reorganized some
of genl_putmixed()'s code without finding any problem, I realized that
there was a problem. The character immediately after \G12345678 would
be copied directly to the output buffer without examination. If that
was the leading backslash for a second encoded sequence, the G and the
hex digits would follow their backslash as just ordinary chars, which
is not what's intended. Or if instead of a backslash the next character
was the input's terminating '\0', the latter would be copied into the
output and the pointer to the input string would be incremented, then
the next loop iteraction would examined whatever followed. If valgrind
is smart enough--and it seems to be--it would complain about accessing
a character that putmixed()'s caller hadn't initialized.
The only use of putmixed() I'm sure about is the what-is code showing
a screen symbol with its explanation, which doesn't exercise either
\G12345678\G12345678 or \G12345678\0. I didn't go hunting to see if
there was someplace that might have an encoded symbol at the end of the
string. what-is still works after this patch....
The only substantive change is adding ``continue'' but I haven't gone
back and undone the reorg that preceded it.
Fix some more of the complaints from clang's static analyzer. The one
in options.c (manipulating warnings symbols) appears to be an actual bug.
All the rest are either because the analysis isn't quite sophicated
enough or outright bogus.
Two of them appear to be because a static routine is attempting to guard
against callers in the same file failing to pass in required output
pointers. Stripping away the check for missing pointer should convince
the analyzer that those output parameters always receive a value. We'll
see once the analysis is eventually re-run....
I think this should fix one of the valgrind complaints. Traps which
didn't use the trap->vl union field never initialized it, leaving a
bit of random garbage in the malloc'd trap structure. (And traps
which overwrote existing ones that did use it didn't reinitialize it
so kept stale data around.) Since those fields weren't in use by
the traps that don't care about them, this didn't provoke any actual
trouble.
Also reformatting....
This should avoid two of the three bogus clang complaints about
retaining the address of a stack variable after it has gone out of
scope.
Plus a recreation of some formatting I did a while back and then
accidentally clobbered before committing.
Fix a couple of the clang static analyzer's warnings.
muse.c has some reformatting. zap.c wasn't triggering any warning about
possible null pointer, but using MON_AT() to maybe avoid m_at() is not
a useful optimization since m_at() is a macro which starts out by using
MON_AT() itself.
When reading a novel, select a random passage which hasn't been shown
already. Once you've run through all the passages, it resets to get
them all again (with new random order that might happen to the be same
order if there aren't many passages). Switching to a different novel--
even another copy of the same one--will cause the previous passage
selection to be discarded and restarted from scratch if the prior book
is read again. Passage tracking for the most recently read novel is
kept across save and restore. (That means I needed to bump EDITLEVEL,
so it will need to be reset to 0 again before release.)
exit_nhwindows() is called before terminate(), and the tty incarnation
destroys all windows--including 'pickinv_cache_win'--without setting
the various index variables used to access them to WIN_ERR, then
terminate() calls freedynamicdata() which calls free_pickinv_cache()
which tries to destroy 'pickinv_cache_win' since it isn't WIN_ERR (if
the perm_invent option has been enabled during that playing session).
Some of the other <interface>_exit_nhwindows() also tear things down
without resetting the variables used to track them, so fixing this in
exit_nhwindows() would have been pretty messy.
Call free_pickinv_cache() before exit_nhwindows() in done(). At the
moment it's only called from done(), so other exit paths won't release
the small chunk(s) of memory used for the alternate inventory window
(if it got created for perm_invent support).
Replace the code that uses strcat with two pointers into the same buffer.
Treated separately, they point at distinct strings (no overlap possible),
but the C standard does disallow that in order to enable optimizations
using block transfer or such, so the tool that complained about it isn't
wrong. The characters getting appended to the output pointer can end
up overlapping the beginning of the other input pointer, conceivably
breaking an implementation that didn't use simple left-to-right byte-at-
a-time copying.
Also, I noticed that wishing for "luck stone" gave me a random gem.
There's code to strip off " stone" and compare against gem types, but it
prevents other code that accepts "foo bar" as a match for "foobar" and
vice versa from finding a match, since "luck" doesn't match anything
once "stone" is gone. So add the four gray stones into the array of
alternate spellings.
Another bit: it now accepts " gem" in addition to " stone" as optional
gem suffix, so "ruby", "ruby stone", and "ruby gem" all yield ruby.
("luck gem" won't work; you'll end up with a random gem-class object.)
And a last other bit: wishing for "lamp (lit) named foo" would yield
an unlit, unnamed lamp because "(lit)" followed by anything didn't match
"(lit)" and threw away everything past the opening paren. Now it will
produce "lamp named foo (lit)"--a lit lamp named "foo". (Wishing for
"lamp named foo (lit)" produces an unlit lamp named "foo (lit)". That's
acceptable to me... I'm not crawling any farther down this hole. Maybe
object formatting should be changed to keep the lit attribute in front
of the name?)
The memory leak (monst->mextra->edog, monst->mextra->mname,
monst->mextra for some monster were not released) I noticed recently
was due to recording a pet's full monster attributes with its corpse.
During save and restore, obj->oextra->omonst was being treated as a
full-fledged monster so worked as intended, but when freed, omonst
was treated as a black box and its mextra details weren't handled.
