mod_ping: Remove ad-hoc command 17:27:40 <Ge0rG> Zash: the Ping thing is absolutely worthless 17:27:55 <Zash> The command provided by mod_ping? 17:27:59 <pep.> To own server? 17:28:14 <Ge0rG> the Ping command in mod_admin_web, whatever it maps to 17:28:29 <Ge0rG> > Pong > 2019-11-07T16:28:16Z What am I supposed to do with that result? 17:28:29 <Zash> Yeah, mod_ping provides that 17:28:41 <Ge0rG> Is it a ping to my own server? Where's the RTT? 17:28:48 <Zash> Dunno if it's useful for more than verifying that the adhoc command system works 17:29:02 <Ge0rG> (it lags, but there is no indication of how much) 17:29:14 <Zash> It can't really test that itself 17:29:52 <Zash> Anyone opposed to deleting it? 17:30:42 <Zash> Half the module 17:42:47 <MattJ> Zash, I'm fine with removing it
