[Maria-discuss] 10.1.x: Got packet bigger than 'max_allowed_packet' bytes
/etc/my.cnf (for many years now) max_allowed_packet = 200M
how can it be that when the whole table file is 54MB large with a setting of 200MB that something is larger then 200MB while obviously it was not too large at insert time at 2016-10-06 but with MariaDB 10.0.x instead 10.1.x?

The particular error message "Got packet bigger than 'max_allowed_packet' bytes" is returned from the client and not the server.
Both the server and the client has a "max_allowed_packet" setting. The client-one is listed here https://dev.mysql.com/doc/refman/5.7/en/mysql-command-options.html.

well, that don't change the fact that i no longer can fetch a base64 encoded binary file uploaded on 2016-10-06 which was already on PHP 7.0, has a count of 32 downloads (not much i know) and the only recent change is MariaDB 10.0.x to 10.1.x

Did you update the MariaDB client bins on the php7 box? I ask because I've always wonder how true the "binary compatible" statement was. I know I have some servers that have the older 10.0 client bins installed talking to a 10.1 server.

besides that PHP is using 'mysqlnd' and so libmysql is not part of the game it MariaDB *is* binary compatible because "symbol versioning" and you don't even need to recompile dbmail, postfix, dovecot and other using libmysql - even if - since i roll my own rpm packages there is no way to have any older binary pieces
however, it smells like https://bugs.php.net/bug.php?id=74021 not only affects fetch_array() but also fetch_assoc() and fetch_row() and is sadly not fixed with 7.1.2 / 7.0.16 released today and already deployed

well, tell that "mysql_upgrade" (part of mariadb) and "myqltuner" (mysqtuner pretends "[!!] Attempted to use login credentials, but they were invalid" when this is ste in the [client] section
mysql_upgrade /usr/bin/mysql_upgrade: unknown variable 'max_allowed_packet=200M'
so currently "mysql" is the only client which a) understands it and b) proceeeds it correctly - what a mess
