strip local variables in tracebacks
sensitive_variables - strip local variables in tracebacks
sensitive_variables it is independent of the web framework
you use and also does not rely on debugging tools to know about the decorator
for things to work.
from sentry_sdk import init from sensitive_variables import sensitive_variables init() @sensitive_variables('password') def login_user(username, password): print("Logging in " + username + " with " + password) # TypeError: unsupported operand type(s) for +: 'NoneType' and 'str' login_user(None, "secret123")
How does it work?
When the decorated function throws an exception,
sensitive_variables walks through the traceback, removes sensitive data from
frame.f_locals and reraises the exception.
This is usually not problematic because a function that just threw an exception is unlikely to still use its local variables.
Why would I use this over Django's decorator?
Django has a decorator also called
sensitive_variables, which this package is inspired by. It adds an attribute to the function that contains the variable names.
Debugging tools have to know about this attribute and respect it. For anything outside of the Django world, this is unlikely to be the case.
This decorator will always work because it actually modifies your locals.
Why would I use this over Sentry's datascrubbing options?
This decorator does not couple your configuration for what is sensitive data to a specific crash reporting tool.
Behavior of the decorator is easily unit-testable (see
Why would I not use this?
This decorator inherently requires custom code for each Python implementation. Currently this is only tested against CPython 2.7, CPython 3.7 and PyPy 2.7.
