Configuration option `purge_environment` not working in ReFrame 4.3.3

[gkaf89]

We are using in our systems ReFrame 4.3.3, installed with EasyBuild 4.9.1 as a module. We set the purge_environment general configuration option to True to ensure that any modules loaded when ReFrame is launched are removed during the compilation and run phases. However, we noticed that modules remain loaded. This does not happen if we set the command line option --purge-env.

Is this known behavior?

Our relevant configuration options:

site_configuration = {                                                                                                                                        
    'general' : [                                                                                                                                             
        {                                                                                                                                                     
            'use_login_shell': True,                                                                                                                          
            'purge_environment': True,                                                                                                                        
        },                                                                                                                                                    
    ],

Hi @gkaf89, which modules system do you use? Also what's the output of reframe -C path/to/your/config.py --show-config=general/0/purge_environment?

Ok, I was able to confirm the bug:

$ reframe -C /path/to/config.py --show-config=general/0/purge_environment
false
$ reframe -C /path/to/config.py --purge-env --show-config=general/0/purge_environment
true
