MYSQL_OPT_RECONNECT is deprecated since mysql 80034

for my information, do we know why it is deprecated: does mysql automatically reconnect without being explictly told ?

I did some research but I have only found some comments regarding the fact that the automatic reconnect didn't work reliably in all situations and didn't leave the connection in a clean state, it was off by default and AFAIK it has no replacements.

I also tried to write some reconnection logic base when mysql_ping() returns false but I couldn't make it work. I could dig deeper if you think this is important.

no, definitely not worth it. Thanks for the explanation !
