[Cppcms-users] C++DB + MySQL disconnect

This isn't specifically a C++CMS query. I'm using C++DB with C++CMS and
FLTK to query a MariaDB server. With other languages and tools I can tell
the client library to auto-reconnect and it does. From the C++DB docs I
should be able to append ";opt_reconnect=1" to the connection string and it
should auto-reconnect. But this has not been reliable, where in other tools
it is. My test FLTK app, which doesn't use a connection pool, will fail
after the idle timeout set in the server (1hr in this case) and *never*
reconnect. My C++CMS apps which use connection pooling kind of work but I
still get random 500s and logs telling me "MySQL went away". Fortunately it
seems to mostly re-connect if I hit another page and then come back to the
one that broke.

But I *HATE* random fails in my projects. I'm not a "80% of the time it
works 100% of the time" kind of guy. So! Is there an easy fix for this? Am
I misinterpreting the docs and writing that option wrong? Or do I just need
to dig into the source and force that client option? I'm not even sure why
its an option. ;-) Anyhow I can't go live with a real C++CMS website and
have this happening.

Versions:

C++DB: 0.3.1
MariaDB: 10.0.38 & 10.2.25
G++: 4.9.2

TIA,
Jon
