14.6. Restricted ExecutionAt one time in Python's history, there was the concept of restricted execution using the rexec and Bastion modules. The first allowed you to modify the built-in objects that were made available to code executing in a sandbox. The second served as an attribute filter and wrapper around your classes. However, due to a well-known vulnerability and the difficulty in fixing the security hole, these modules are no longer used or accessible; their documentation serves only those maintaining old code using these modules. |
