Somewhere around line 1000. I don't think we want shtree to output to
stdout, do we? That would break a few things, and it does. We might want
it to go to stderr or tracefile, but defintely not stdout.
---8<---
static void
showtree(union node *n)
{
trace_puts("showtree called\n");
shtree(n, 1, NULL, stdout);
}
#endif /* DEBUG */
--->8---
And somewhere around line 11847:
---8<---
#if DEBUG
showtree(n);
#endif
--->8---
We might want to do this instead:
#if DEBUG > 2
if (debug && (n != NEOF))
showtree(n);
#endif
Without checking on 'debug', we always get output from showtree. I don't
think we want that.
Without '(n != NEOF)' we may get segfaults.
And 'DEBUG > 2' could be a good idea too. What do you say?
The other thing is that there are a few places where %x should read 0x%x,
maybe; at least for consistancy:
-> 254: bb_error_msg("bug on %d: closing %d(%x)", \
3821: TRACE(("dowait(0x%x) called\n", wait_flags));
3828: TRACE(("wait returns pid=%d, status=0x%x, errno=%d(%s)\n",
3846: "from 0x%x to 0x%x\n",
-> 3990: TRACE(("showjobs(%x) called\n", mode));
-> 4051: TRACE(("getstatus: job %d, nproc %d, status %x, retval %x\n",
5632: TRACE(("evalbackcmd done: fd=%d buf=0x%x nleft=%d jp=0x%x\n",
