Hello
While understanding how refs work inside nupas, i decided to try to implement
the same function nupas has to find mailbox references in acid langauge, so i
did:
defn findmboxrefs(mb,fids) {
local f, refs;
f=fids;
while f!=0 do {
print("f=", f\X,"\n");
if f->mb==mb then
refs++;
print("f->mb=", f->mb\X," =? mb=",mb\X,"\n");
f=f->next;
}
print("refs ==", refs,"\n");
}
using a Broken nupas (broked by an assert call), i got this:
acid: findmboxrefs(*checkmboxrefs:mb,fids);
f=0x0003a090
f->mb=0x00000000 =? mb=0x0004a468
f=0x0004bf68
f->mb=0x8d1c2444 =? mb=0x0004a468
f=0x89ffffe4
<stdin>:75: (error) indir: can't read address 0x89ffffe4: bad arg in system call
is that related to something wrongly done in the acid function?
that means that there is an f which is pointing to an incorrect place?
or means that as the process is broken, acid cannot read some parts of it?
i forgot another possible issue, the broken process is owned by another user, i
just chmod'ed /proc/pid/*. . . .
thanks
