Hello

I want to use custmized option for security configuration one contrib
library. Currently customized options are usable only for default
configuration, because everybody can change it. It is substitution of global
variables.

Decision if option is protected or not can be based on name of option. Like:

customized_option = (utl_file)

utl_file.protected.dir = '/aaa:/bbb' .. can be modified by superuser
utl_file.readonly.dir = '/aaa:/mm' .. nobody can modify it

Regards
Pavel Stehule

I dislike making it depend on spelling. There was discussion of this
problem before, and we had a much saner answer: when the module that
defines the variable gets loaded, discard any local setting if the
correct protection level of the variable is SUSET or higher. See the
archives.

Pavel,

Is there any chance you can work on this? I suspect I won't have time.

You can see the original thread here:

cheers
