Refusing clobbering of {HandleError} installed on externally supplied DBI handle

[onelesd]

Not sure which module to blame here. But the error goes away by commenting this section of Dancer::Plugin::Database::Core.pm

    # To support the database_error hook, use DBI's HandleError option
    #$settings->{dbi_params}{HandleError} = sub {
    #    my ($error, $handle) = @_;
    #    $hook_exec->('database_error', $error, $handle);
    #};

Sorry for the slow response - looks like both Dancer::Plugin::Database and something else in your app are setting HandleError.

Maybe Dancer::Plugin::Database should provide an option to disable the error hook handler if you don't need it?

@bigpresh This just hit me when using DBIx::Class on an existing dbh inside Dancer - I worked around by creating a second dbh connection (which I'm not enamored with, because I don't like doubling my database connections). Going to look into submitting a patch to provide an option to disable the error hook handler. Please let me know if you have input

I get same error. I do not use two connections. I even do not know which module may take precedence to setting up handler second time.
