So I am trying to convert tables into using opaque of cardinality since thats
more memory efficient (or counting bloomfilters for that matter):
works: if table (0) converted to (1)
errors: if table (2) converted to (3)
Details: I am trying the following, original table (0) converted to (1):
(0) global likely_scanner: table[addr,port] of set[addr] &read_expire=1 day
&synchronized ;
(1) global c_likely_scanner: table[addr] of opaque of cardinality
&default = function(n: any): opaque of cardinality { return
hll_cardinality_init(0.1, 0.95); }
&read_expire=1 day ;
ERRORS:
(2) global likely_scanner: table[addr,port] of set[addr] &read_expire=1 day
&synchronized ;
Converted table:
(3) global c_likely_scanner: table[addr,port] of opaque of cardinality
&default = function(n: any): opaque of cardinality { return
hll_cardinality_init(0.1, 0.95); }
&read_expire=1 day ;
I get this error:
check-knock.bro, line 58: &default function type clash
(&default=anonymous-function{ return (hll_cardinality_init(0.1, 0.95))})
Question:
how do I declare (3) so that I can avoid the "&default function type clash"
error above.
I am not sure what am I doing wrong in the declaration. Any thoughts/advice how
to get past this issue ?
Thanks,
Aashish
