[Rt-devel] RT.pm LoadConfig sub ... is this a logic error?

Hi folks,

kind of new with RT.  I copied RT_Config.pm to RT_SiteConfig.pm and then I
had made a change to my RT_SiteConfig.pm.  I changed

Set($LogToSyslog    , 'debug');
Set($LogToFile      , undef);


Set($LogToSyslog    , undef);
Set($LogToFile      , 'debug');

[Don't ask why ;-) ]

When I did not see the effect of the change I did a trace of the code
dealing with it.

I believe there maybe a "logic" error in the "LoadConfig" sub [see code
snippet below].  As the comments say, first load the "core config" and
then the site.  But the actual code loads the site first and then the
core.  To me that would reset values to the "core" default (due to the
"undef" value in the "Set".

I would have done it differently [unless I am misunderstanding something]
-- remove the "unless defined $_[0]" clause in the "Set" sub, and move the
"if (...)"  clause after the "require $CORE_CONFIG_FILE ..." statement.

For your amusement,

in RT.pm

=head2 LoadConfig

Load RT's config file. First, go after the core config file.
After that, go after the site config.


sub LoadConfig {
     local *Set = sub { $_[0] = $_[1] unless defined $_[0] };
    if ( -f "$SITE_CONFIG_FILE" ) {
        require $SITE_CONFIG_FILE
          || die ("Couldn't load RT config file '$SITE_CONFIG_FILE'\n$@");
    require $CORE_CONFIG_FILE
      || die ("Couldn't load RT config file '$CORE_CONFIG_FILE'\n$@");
