sentry: Ignore all SuspiciousOperation loggers. django.security.DisallowedHost is only one of a set of exceptions that are "SuspiciousOperation" exceptions; all return a 400 to the user when they bubble up[1]; all of them are uninteresting to Sentry. While they may, in bulk, show a mis-configuration of some sort of the application, such a failure should be detected via the increase in 400's, not via these, which are uninteresting individually. While all of these are subclasses of SuspiciousOperation, we enumerate them explicitly for a number of reasons: - There is no one logger we can ignore that captures all of them. Each of the errors uses its own logger, and django does not supply a `django.security` logger that all of them feed into. - Nor can we catch this by examining the exception object. The SuspiciousOperation exception is raised too early in the stack for us to catch the exception by way of middleware and check `isinstance`. But at the Sentry level, in `add_context`, it is no longer an exception but a log entry, and as such we have no `isinstance` that can be applied; we only know the logger name. - Finally, there is the semantic argument that while we have decided to ignore this set of security warnings, we _may_ wish to log new ones that may be added at some point in the future. It is better to opt into those ignores than to blanket ignore all messages from the security logger. This moves the DisallowedHost `ignore_logger` to be adjacent to its kin, and not on the middleware that may trigger it. Consistency is more important than locality in this case. Of these, the DisallowedHost logger if left as the only one that is explicitly ignored in the LOGGING configuration in `computed_settings.py`; it is by far the most frequent, and the least likely to be malicious or impactful (unlike, say, RequestDataTooBig).
