Hello,
I am experiencing problems downloading an email from a POP server using
imap2002e library.
As far as I can tell now the code is looping in rfc822.c
rfc822_parse_content() using up 50% of my cpu
To prevent the hang we are detecting this loop in
rfc822_parse_content() and forcing the code to exit() out:
case TYPETEXT: /* text content */
if (!body->parameter) { /* default parameters */
body->parameter = mail_newbody_parameter ();
body->parameter->attribute = cpystr ("CHARSET");
body->parameter->value = cpystr ("US-ASCII");
}
/* count number of lines */
while (i--) {
if ((SNX (bs)) == '\n') body->size.lines++;
if ( i > bs->size ) {
// this should not happen...
// GOAL: Here, some users force the c-client lib
// to hang forever (but the process gets
killed
// by apache).
// NOTE: I used exit() to flush the log buffers.
mm_fatal("Content length broken");
exit(1);
}
}
break;
The problem is that in the lines before
body->size.bytes = body->contents.text.size = i = SIZE (bs);
SIZE(bs) returned 0xfffffffd.
Exit() was a first shot to detect this problem, as a first workaround I
could probably just break out of the while loop, and continue. Is this
safe to do?
Right now I am debugging the code to see what caused the offsets to be
incorrect.
Any input on this or if this even is a known issue will be appreciated
:-)
Best regards,
Sebastian Voges
