How To Dynamically Add a Path to the Perl @INC At Compile-Time

Author: erics, April 16th, 2021

The key is to define a variable first, then use the BEGIN block to initialize the variable, then reference the variable in use lib $var; later on ;-} For example, enable a module contained in the same directory as a script called via the PATH:

#!/ussr/bin/env perl
use strict;
use warnings;

our $scriptPath;

BEGIN {
        eval {
                use File::Basename;
                use File::Spec;
                $scriptPath = dirname(File::Spec->rel2abs(__FILE__));
                1;  
        } or do {
                die "$0 use CRASHED: $@";
        };  
}

use lib $scriptPath;

eval {
        use MyModule::ABC;
        1;
} or do {
        die "$0 use CRASHED: $@";
};

#!/ussr/bin/env perl

use strict;

use warnings;

our $scriptPath;

BEGIN {

eval {

use File::Basename;

use File::Spec;

$scriptPath = dirname(File::Spec->rel2abs(__FILE__));

} or do {

die "$0 use CRASHED: $@";

};

}

use lib $scriptPath;

eval {

use MyModule::ABC;

} or do {

die "$0 use CRASHED: $@";

};

How To Protect a WordPress Site Using Basic Auth in Apache 2.4

Author: erics, August 25th, 2016

Apache 2.4 changed the security configuration directives a bit. Here is an example using basic auth:

<Directory "/path/to/your/wordpress">
   AllowOverride All 
   Options +FollowSymLinks +ExecCGI -Indexes
   Order allow,deny
   Allow from all

   <RequireAll>
      AuthType Basic
      AuthName "Protected Resource"
      AuthUserFile /path/to/your/.htpasswd
      Require valid-user
   </RequireAll>

</Directory>

AllowOverride All

Options +FollowSymLinks +ExecCGI -Indexes

Order allow,deny

Allow from all

AuthType Basic

AuthName "Protected Resource"

AuthUserFile /path/to/your/.htpasswd

Require valid-user

</RequireAll>

</Directory>

What tripped me up for a while was that I still had the Require all granted directive inside the container, and that needed to be removed for the auth to work.
