This commit is to fix issue mscdex#181. According to https://github.com/mscdex/node-mariasql/blob/master/lib/Client.js#L633 , The protocol-level pings can be enabled by setting both 'pingInactive' and 'pingWaitRes' variablei as following: a. 'pingInactive' to how many milliseconds to wait before sending a ping when no queries are pending, b. AND 'pingWaitRes' to how many milliseconds to wait for a ping response before assuming a lost/dead connection. For example, If you want to check a connection state per 60 seconds, we have to define both 'pingInactive' and pingWaitRes. It means that the "MySQL server has gone away" issue will be always generated in case that we declare the timout with one between 'pingInactive' and 'pingWaitRes'. Let's support an optional conditional operator instead of "AND" operation conditions. * Example source code: [foo.js] pingInactive: 60000, pingWaitRes: 60000 * Before applying this patch: events.js:160 throw er; // Unhandled 'error' event ^ Error: MySQL server has gone away at Error (native) * How to monitor a sleep time of database on MariaDB server: $ sudo apt-get install mytop [enter] $ mytop -u root -p**** ourjs [enter] MySQL on localhost (10.0.29) load 0.32 0.30 0.26 2/580 9391 up 0+14:33:20 [07:47:10] Queries: 1.7k qps: 0 Slow: 0.0 Se/In/Up/De(%): 02/00/00/00 Sorts: 0 qps now: 1 Slow qps: 0.0 Threads: 3 ( 1/ 2) 00/00/00/00 Key Efficiency: 100.0% Bps in/out: 0.9/127.1 Now in/out: 21.3/ 2.9k Id User Host/IP DB Time Cmd State Query -- ---- ------- -- ---- --- ----- ---------- 754 ourjs localhost:34766 test 38 Sleep $ cat /proc/754/stat $ cat /proc/754/status * How to change a default timeout of Mariadb server: $ sudo vi /etc/mysql/mariadb.conf.d/50-server.cnf [mysqld] wait_timeout = 120 (default value is 28800) interactive_timeout = 120 (default value is 28800) Signed-off-by: Geunsik Lim <[email protected]>

It's stragne. I still have got "MySQL server has gone away" after passing the specified wait_timeout of mariadb server when I defined a "pingInactive" variable to avoid connection time-out state.
How to change a default timeout of Mariadb server:
$ sudo vi /etc/mysql/mariadb.conf.d/50-server.cnf
[mysqld]
wait_timeout = 28800
interactive_timeout = 28800
loge messages:
events.js:160
throw er; // Unhandled 'error' event
^
Error: MySQL server has gone away
at Error (native)
