Description

I'm sorry for too late to fix this bug.

Here is an example about the broken of traffic_shell(reported by Esmq<[e-mail]> ):

echo 'show:proxy-stats' | sudo /usr/local/trafficserver/bin/traffic_shell
Successfully Initialized MgmtAPI in /usr/local/trafficserver-4.0.1/var/trafficserver 
trafficserver> 
Document Hit Rate -------- 0.000000 %    *
Ram cache Hit Rate ------- 0.000000 %    *

Client Throughput -------- 18.100512 MBit/Sec

The root cause is that StatBinaryEval() use RecInt type to hold the result of div operation when operands are RecInt.

Issue Links

• is duplicated by: TS-2234 traffic_line query interface lose efficacy
• relates to: TS-1805 Stats: show:proxy-stats in traffic_shell only have Client Throughput, all others '0'
• relates to: TS-1995 After TS-1740, traffic_shell and traffic_line starts to show zero stats in some fields.
