Hello.
I am trace looping proc in GDB. And see, that it loop's in unix_check at
unix.c:822.
====================
0x0809dace in unix_check (stream=0x8142738) at unix.c:826
826 in unix.c
(gdb) where
#0 0x0809dace in unix_check (stream=0x8142738) at unix.c:826
#1 0x0809db29 in unix_close (stream=0x8142738, options=0) at unix.c:577
#2 0x080693fa in mail_close_full (stream=0x8142738, options=0) at mail.c:1354
#3 0x08051438 in main (argc=1, argv=0xbffffae4) at imapd.c:383
====================
Step-by-step debuging:
in 'unix_check'(unix.c:826) do:
step1: in 822 str: "unix_rewrite" return 0 and go to 'else'
step2: else unix_unlock (LOCAL->fd,stream,&lock);
step3: mail_unlock (stream); /* unlock the stream */
step4: MM_NOCRITICAL (stream)
==> go to "mm_nocritical (s=0x8142738) at imapd.c:4419"
in 'mm_nocritical':
step5: if (!--critical && (state == LOGOUT)) {; _is TRUE_
step6: if (s && (stream != s) && !s->lock && (s->dtb->flags &
DR_XPOINT)); _is FALSE_
step7: longjmp (jmpenv,1); /* die now */
==> go to "main (argc=1, argv=0xbffffae4) at imapd.c:382"
in 'main':
step8: if (stream && !stream->lock && (stream->dtb->flags &
DR_XPOINT)); _is TRUE_
step9: stream = mail_close (stream);
==> go to "mail_close_full (stream=0x8142738, options=0) at mail.c:135"
in 'mail_close_full':
step10: if (stream) {; _is TRUE_
step11: if (stream->dtb) (*stream->dtb->close) (stream,options);
==> go to: "unix_close (stream=0x0, options=0) at unix.c:571"
in 'unix_close':
step12: int silent = stream->silent;
step13: stream->silent = T; /* go silent */
again
step14: int silent = stream->silent;
step15: stream->silent = T; /* go silent */
again
step16: int silent = stream->silent;
and
step17: if (options & CL_EXPUNGE) unix_expunge (stream,NIL,NIL); _is
FALSE_
step18: else if (LOCAL->dirty) unix_check (stream);
AND WE AGIAN GO to:
unix_check (stream=0x8142738) at unix.c:816
It's looping. Does anybody can help?
