Working through some really annoying case-sensitivity / insensitivity issues with MariaDB 10.x on macOS High Sierra.
It seems as though a simple mysqldump -u root db_name > file.sql works as expected. All tables are dumped with contents, all casing is as-typed, meaning the export file has initial caps on table names.
But as soon as I add a table name to the mysqldump command, the output changes to lowercase on macOS, which is causing havoc when I check in schema.sql to run on TravisCI.
mysqldump -u root db_name > file.sqlwrites table names as expected
mysqldump -u root db_name TABLE_NAME > file.sqlwrites table names all lowercased!
Take the following Activity table:
CREATE TABLE `Activity` ( `id` int(11) NOT NULL AUTO_INCREMENT, `code` varchar(512) NOT NULL DEFAULT '', `methodString` varchar(512) DEFAULT NULL, `description` varchar(512) NOT NULL DEFAULT '', `category` varchar(512) NOT NULL DEFAULT '', `entityModel` varchar(512) DEFAULT NULL, `teamLevel` tinyint(1) DEFAULT NULL, `orderLevel` tinyint(1) DEFAULT NULL, `adminOnly` tinyint(1) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; In the DB as uppercase Activity, all good. If this is the only table in the DB, a mysqldump -u root db_name > file.sql will write out:

Is this just a bug with mysqldump in MariaDB 10.x on macOS? I know macOS is not case-sensitive, but it CAN output as-typed case mysqldump output. Unfortunately we’ve spec’d table names as arguments and now TravisCI is failing because Linux is case-sensitive.
I’d really like to avoid setting lower_case_table_names=1 on travis, and instead make macOS MariaDB mysqldump work with capitals!
