Yunkai Zhang updated TS-2174:
-----------------------------
Description:
I'm sorry for too late to fix this bug.
Here is an example about the broken of traffic_shell(reported by
Esmq<[email protected]> ):
{code}
echo 'show:proxy-stats' | sudo /usr/local/trafficserver/bin/traffic_shell
Successfully Initialized MgmtAPI in
/usr/local/trafficserver-4.0.1/var/trafficserver
trafficserver>

Ram cache Hit Rate ------- 0.000000 % *
Bandwidth Saving --------- 0.000000 % *

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

Since I nearly didn't use traffic_shell, and traffic_line works well for me, I
didn't notice this bug.
The root cause of this issue is that traffic_shell use RecFloat type to read
most stats variables, though these variables are no longer RecFloat type after
applied TS-1740, as a result bad conversion occurred.
We should make traffic_shell works as traffic_line, use the correct conversion
to read stats variables.
> traffic_shell/traffic_line miss some stats value
