rpn expressions without DEF or CDEF variables SHOULD BE supported

[human]

Use-case for rpn without variables is "smart" HRULE.

rrdtool graph $dir-$hours.png --lazy \
  ...
  CDEF:limit_top=LTIME,$(( 24 * 60 * 60)),%,$(( 8 * 60 * 60)),$(( 20 * 60 * 60)),LIMIT,UN,32000,16000,IF \
  CDEF:limit_mid=limit_top,2,/ \
  "LINE:limit_mid#666600 LINE2:limit_top#666600"

Now I have to use ugly constructions with fake variables:

  CDEF:limit_top=foo,foo,-,LTIME,+,$(( 24 * 60 * 60)),%,$(( 8 * 60 * 60)),$(( 20 * 60 * 60)),LIMIT,UN,32000,16000,IF

So CDEF without variables IS not error.

And one more note, is it possible to hide CC list (and e-mail addresses) from anonymous persons ? That may slow down address crawlers.

a CDEF variable must have a 'resolution' without DEF connection it has no resultion ... changeing that is pretty deep ... in any event, the most efficient way for getting around this is to use

CDEF:x=foo,POP,...

take a look at the code ... implementation ideas for such a change are welcome ...

re your second issue ... I am not aware that there is a way to hide the cc list in trac. cheers tobi
