WP Multisite doesn't use custom db-error.php or have a hook

  • I suppose this is a feature request. I don’t see a way to configure a Multisite install to use the same wp-content/db-error.php file as a single wp site install uses. Instead where the db is down the page dies on “Error establishing database connection” wrapped in an <h1>.

    It could be a complication of using the HyperDB plugin, but it appears that on line 104 of wp-includes/ms-settings.php when the db is down get_blog_details() obviously fails and wp-includes/ms-load.php:ms_not_installed() is called. Unfortunately ms_not_installed() does not redirect to db-error.php, and instead dies, returning
    $title = /*WP_I18N_FATAL_ERROR*/’Error establishing database connection’/*/WP_I18N_FATAL_ERROR*/;

    Obviously i could hack in a call to wp-includes/functions.php: dead_db() in ms-load.php, but i try to avoid any core hacking to make upgrades easier.

    Does anyone have a suggestion for overriding this behavior cleanly? perhaps something in wp-WP_CONTENT_DIR/sunrise.php ?

    I suppose if somebody else is interested in the dirty hack here it is. In “function ms_not_installed” on line 224 of wp-includes/ms-load.php, insert dead_db();
    like this…

    <br />
function ms_not_installed() {<br />
    dead_db(); //hacked this in so we can get use our custom db-error.php<br />
