<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">for me this would make more sense turning this if around and move the realtime call to the else part.
if we dont have a name and cant get it from *var then destroy var, throw a warning.... Else just go ahead and do the realtime lookup.

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">r1395 broke two things:
- It added warnings for situations that shouldn't get a warning. (Bad placement of the warning.) [schmidts found this]
- It was allowed to have an empty sippeer name. (No check after get_name_from_variable().)
However, both before and after r1395, the following was broken:
- For port-insecure matches, it was allowed to have an empty peer name. (Because of the use of ast_load_realtime_multientry.)
- Realtime lookups for name NULL were attempted with undefined behaviour (res_config_sqlite returns a warning "1 parameter and 1 value at least required" and no results)
This patch does the following:
- Fix the warning to only be emitted when there actually is an empty peername found. (Both in case of sipregs and sippeers.)
- Disallow the empty peername always. Even for port-insecure matches.
Notes:
- For sippeer matching: if name is empty, the match is used and discarded at the end with a warning. (The behaviour as before r1395.)
- For the port-insecure matching of sipregs: if name is empty, the match is discarded and lookup continues. (This wasn't available before r1395.)
- For other matching of sipregs: if name is empty, a warning is emitted, the match is discarded and lookup continues. (This was undefined before r1395; the NULL-name was refused, the empty-name was allowed.)
