Hi internals, Building PHP 7.4 against libmysql rather than mysqlnd has been broken for quite a while and only recently noticed in https://github.com/php/php-src/pull/4316. Clearly none of us are using libmysql and none of our CI jobs test it. Now that it compiles again, there are many build warnings, as well as about 10 failing PDO MySQL tests and 20 failing MySQLi tests.
This is not good. I think that we either need an interested party to support these bindings, or else drop support for building against libmysql. Regards, Nikita
