This module implements
file_accessdir inside of Node.js.
open_basedir: Validates that all
require's are inside these directories.
fsmodule methods are verified against these directories.
If a path is not validated, it will throw an error (either throw or err out the callback).
The goal for this module is to help when you are loading 3rd party modules and you need to restrict their access. A few examples of this come to mind:
When you use this module, you
require it and configure it in your controlled script.
Then any call/require after that will be forced to use these predefined scoped directories.
override other methods to gain access. I have tried to prevent this with
on the two
Object's that are modified so that they can't be modified again.
The constructor to
fs-lock can not be called more than once, this means that once the
settings are in place, they can not be overrided (except for testing, view code to see that).
The only overrides available for this are a set of Environment variables that are read at init time. Environment vars where chosen because if you have access to them you probably have access to the script too.
Both of these support the standard
: separator and will be auto processed when
the module is loaded.
