# add variables set via param to $vars for processing
for my $k ( keys %{ $self->{VARS} } ) {
$vars->{$k} = $self->{VARS}->{$k};
}
This loop is not necessary, we could do the same with
$vars = { %$vars, %{ $self->{VARS} } };
After a quick benchmark, it gains 100 microseconds when we pass 170 vars
to the template.
Test plan:
Do some clicks on the interface, everything should be ok.

This function returns the theme and language to be used for rendering the UI.

It also returns the list of themes that should be applied as a fallback. This is

used for the theme overlay feature (i.e. if a file doesn't exist on the requested
|
|
theme, fallback to the configured fallback).
|
|
|
|
Important: this function is used on the webinstaller too, so always consider
|
|
the use case where the DB is not populated already when rewriting/fixing.
