DetailsEdit

This variable was set to empty string in DefaultSettings.php, but it was not an actual setting.

It was used to store a MySQL link identifier (return value of mysql-connect()).

Since MediaWiki 1.2, this variable was unused.

In MediaWiki 1.17 (a060794480fe), it was removed from DefaultSettings.php.
